xpaset or +xpaget command will return without waiting for the remote callback to +complete.

To do this, +configure for a different install directory: + + ./configure --prefix= +e.g., + ./configure --prefix=/soft/saord + +Programs will be installed in /soft/saord/bin, libraries in /soft/saord/lib, +include files in /soft/saord/include, and man pages in /soft/saord/man. +Indeed, we do this at SAO and recommend it as a general rule, in order +to keep SAORD software in one place that does not conflict with other +installations. Note that you will need to add the bin directory to +your path and the man directory to MANPATH. + +The build ("make") takes only a minute or so on modern machines. To +monitor its progress and/or check for errors, redirect output to a file +and use the 'tail' command: + + make >& foo.log &; tail -f foo.log # csh +or + make 1>foo.log 2>&1 &; tail -f foo.log # sh, bash + + +Details of Installation +======================= + + NB: These are generic installation instructions, modified for XPA. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +The simplest way to compile this package is: + + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 1. `cd' to the directory containing the package's source code and type + "./configure". This runs a configuration script created by GNU + autoconf, which configures XPA for your system and creates a + Makefile. The configure script allows you to customize the XPA + configuration for your site; for details on how you can do this, + type "./configure -help" or refer to the autoconf documentation (not + included here). The XPA "configure" script supports the following special + switch(es) in addition to the standard ones: + + --enable-shared=yes|link + + Build shared libraries in addition to the + default static library. There are two options: + + If the value is "yes", shared libraries are + built but not used to link xpa programs. + + If the value is "link", shared libraries are + used to link xpa programs. If therefore becomes + your responsibility to put the shared library + where it can be found (or use LD_LIBRARY_PATH). + + --enable-threaded-xpans + Build xpans to support separate threads for + handling name server requests and xpa proxy + callbacks. This is recommended if you are going + to enable proxy handling in xpans (-P), since + XPA long callbacks via proxy can interfere + with the name server functions. (You still have + to start xpans with -P 2 to use 2 threads.) + + --with-tcl= + Force build Tcl support using parameters found + in /tclConfig.sh. Configure will look for + the Tcl config script in standard places and + will enable Tcl support if found. It will abort + if tclConfig.sh points to a non-existent tcl.h + file (some versions of Linux have shown this + behavior). Use this switch to override the + standard locations or to force a build even + if tcl.h is not found (e.g. if you are going to + install tcl as part of a larger build). With + Tcl support enabled you can execute: + + make tclxpa + + to generate the XPA package as a shared Tcl + object, loadable using Tcl "package require". + Contact us with problems -- its been a bear to + get this even half-way right. + + --with-threads + If you are going to link XPA into a threaded + program, you need to specify --with-threads. + This add -D_REENTRANT to the compiler flags, + which tells gcc to use thread-safe versions of + global system variables such as errno. No code + changes are made to XPA. Please note that all + XPA calls must be in a single thread: XPA is + not thread-safe in and of itself but does work + in threaded programs. + + --with-gtk= + Build with support for adding xpa to a gtk + loop. The specified include directory must + contain the gtk directory which itself contains + gtk.h, e.g.: + + --with-gtk=/usr/local/include/gtk-1.2 + + which contains gtk/gtk.h + + Standard options are listed below. the most important of which + are --exec-prefix and --prefix (to specify where to install), and + --x-includes=DIR and --x-libraries=DIR (for non-standard X installations). + We recommend --prefix be set to a directory that will hold saord software + (e.g., --prefix=/soft/saord) in order to make management of our software + easier. + + NB: be sure to use only absolute path names (those starting with "/") + in the --prefix and --exec_prefix options. (The configure options we + use at SAO for various machines are given as examples in the script + file called "saoconfig" in this directory.) + + 2. Type `make' to compile the package. + This will create a library archive called libxpa.a. It also will create + the programs xpaget, xpaset, xpainfo, xpaaccess, xpans, and xpamb. It + also will create the libxpa.so shared object if requested using the + --enable-shared switch + + 3. You can build the libxpa.so shared library manually by executing: + + make shlib + + at this point. This will not contain Xt or Tcl routines. If Tcl support + has been enabled (see --with-tcl above), you can build a shared library + called libtclxpa.so that supports the tclxpa package (i.e. Tcl routines + are contained in it) by executing: + + make tclxpa + + This shared library will be loaded automatically with the Tcl command: + + package require tclxpa 2.1 + + assuming, of course, that your shared library can be found by Tcl. + + 4. Type "make install" to install XPA's libraries and binaries in + standard places. You'll need write permission on the installation + directories to do this. The installation directories are + determined by the "configure" script and may be specified with + the --prefix and --exec_prefix options to "configure". See the + Makefile for information on what directories were chosen; you + can override these choices by modifying the "prefix" and + "exec_prefix" variables in the Makefile. + + 5. There are .html help files in the doc directory. You can copy + these files to a more convenient location, if you like. We + did not automate this step because we did not know where to + copy these files by default. (NB: The help.html file is the + top level index file.) + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment: + + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + +You also can use this facility to specify a compiler other than the default +gcc (if it exists). + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/lib', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH': + +e.g., + ./configure --prefix=/soft/saord + +Programs will be installed in /soft/saord/bin, libraries in /soft/saord/lib, +and include files in /soft/saord/include. We recommend this as a general rule, +in order to keep SAORD software in one place that does not conflict with other +installations. Note that you will need to add the bin directory to your path. + + You can specify separate installation prefixes for architecture-specific +files and architecture-independent files. If you give `configure' the option +`--exec-prefix=PATH', the package will use PATH as the prefix for installing +programs and libraries. Documentation and other data files will still use the +regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options. + +If you have questions, please contact us at: saord@cfa.harvard.edu. + + Eric Mandel diff --git a/LICENSE b/LICENSE new file mode 100644 index 0000000..a9c1e78 --- /dev/null +++ b/LICENSE @@ -0,0 +1,21 @@ +XPA is distributed under the terms of The MIT License (MIT), reproduced below. + +Copyright (c) 2014-2016 Smithsonian Institution + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Because XPA works both at the programming +level and the shell level, it is a powerful tool for unifying any +analysis environment: users and programmers have great flexibility in +choosing the best level or levels at which to access XPA services, and +client access can be extended or modified easily at any time. + +A program becomes an XPA-enabled server by defining named points of +public access through which data and commands can be exchanged with +other client programs (and users). Using standard TCP sockets as a +transport mechanism, XPA supports both single-point and broadcast +messaging to and from these servers. It supports direct communication +between clients and servers, or indirect communication via an +intermediate message bus emulation program. Host-based access control +is implemented, as is as the ability to communicate with XPA servers +across a network. + +XPA implements a layered interface that is designed to be useful both +to software developers and to users. The interface consists of a +library of XPA client and server routines for use in C/C++ programs and +a suite of high-level user programs built on top of these libraries. +Using the XPA library, access points can be added to Tcl/Tk programs, +Xt programs, or to Unix programs that use the XPA event loop or any +event loop based on select(). Client access subroutines can be added +to any Tcl/Tk, Xt, or Unix program. Client access also is supported at +the command line via a suite of high-level programs. + +To build XPA, see the INSTALL instructions (which are based on +standard instructions for building software using GNU configure). + +Documentation for XPA is contained in the doc subdirectory (where the +help.html file is the top-level index). + +If you have questions, please contact us at: saord@cfa.harvard.edu. + + Eric Mandel + +XPA is distributed under the terms of The MIT License. diff --git a/acl.c b/acl.c new file mode 100644 index 0000000..24b4489 --- /dev/null +++ b/acl.c @@ -0,0 +1,568 @@ +/* + * Copyright (c) 1999-2003 Smithsonian Astrophysical Observatory + */ + +/* + * + * acl.c -- xpa access control list management + * + */ + +#include + +/* + *---------------------------------------------------------------------------- + * + * + * Private Routines + * + * + *---------------------------------------------------------------------------- + */ + +/* this is the head of the global list -- too lazy to do anything more */ +static XACL aclhead=NULL;

XPAAcl: Access Control for XPA Messaging

+ + +

Summary

+

+XPA supports host-based access control for each XPA access point. You +can enable/disable access control using the XPA_ACL environment +variable. You can specify access to specific XPA access points for +specific machines using the XPA_DEFACL and XPA_ACLFILE environment +variables. By default, an XPA access point is accessible only to +processes running on the same machine (same as X Windows). + + +

Description

+

+When INET sockets are in use (the default, as specified by the +XPA_METHOD environment variable), XPA supports a host-based +access control mechanism for individual access points. This mean that +access can be specified for get, set, or info operations for each +access point on a machine by machine basis. For LOCAL sockets, access +is restricted (by definition) to the host machine. + +

+XPA access control is enabled by default, but can be turned off by +setting the XPA_ACL environment variable to false. +In this case, any process can access any XPA server. + +

+Assuming that access control is turned on, the ACL for an individual +XPA access point is set up when that access point is registered +(although it can be changed later on; see below). This can be done in +one of two ways: + +Firstly, the XPA_ACLFILE environment variable can defined to +point to a file of access controls for individual access points. The format +of this file is: +

+ class:name ip acl
+
+The first argument is a template that specifies the class:name of the +access point covered by this ACL. See +XPA Access Points and Templates +for more information about xpa templates. + +

+The second argument is the IP address (in human-readable format) of +the machine which is being given access. This argument can be +* to match all IP addresses. It also can be $host +to match the IP address of the current host. + +

+The third argument is a string combination of s, g, +or i to allow xpaset, xpaget, or +xpainfo access respectively. The ACL argument can be ++ to give sgi access or it can be - to turn +off all access. + +

+For example, +

+  *:xpa1  somehost sg
+  *:xpa1  myhost +
+  * * g
+
+will allow processes on the machine somehost to make xpaget and xpaset calls, +allow processes on myhost to make any call, and allow all other hosts to +make xpaget (but not xpaset) calls. + +Secondly, if the XPA_ACLFILE does not exist, then a single +default value for all access points can be specified using the +XPA_DEFACL environment variable. The default value for this +variable is: +
+  #define XPA_DEFACL "*:* $host +"
+
+meaning that all access points are fully accessible to all processes +on the current host. Thus, in the absence of any ACL environment variables, +processes on the current host have full access to all access points +created on that host. This parallels the X11 xhost mechanism. + +

+Access to an individual XPA access point can be changed using the -acl +parameter for that access point. For example: +

+  xpaset -p xpa1 -acl "somehost -"
+
+will turn off all access control for somehost to the xpa1 access point, while: +
+  xpaset -p XPA:xpa1 -acl "beberly gs"
+
+will give beberly xpaget and xpaset access to the access point whose +class is XPA and whose name is xpa1. +

+Similarly, the current ACL for a given access point can be retrieved using: +

+  xpaget xpa1 -acl
+
+Of course, you must have xpaget access to this XPA access point to +retrieve its ACL. + +

+Note that the XPA access points registered in the xpans +program also behave according to the ACL rules. That is, you cannot +use xpaget to view the access points registered with xpans unless +you have the proper ACL. + +

+Note also when a client request is made to an XPA server, the access +control is checked when the initial connection is established. This +access in effect at this time remains in effect so long as the client +connection is maintained, regardless of whether the access fro that +XPA is changed later on. + +

+We recognize that host-based access control is only relatively secure +and will consider more stringent security (e.g., private key) in the +future if the community requires such support. + + + + + +

XPA ChangeLog

+ +

+This ChangeLog covers the XPA 2 implementation. It will be updated +as we continue to develop and improve XPA. The up-to-date version can be +found here. + +

Public Release 2.1.16 (TBD)

+
    +
  • Ensure that mingw utilizes Windows error codes instead of *nix codes +
+ +

Public Release 2.1.15 (July 23, 2013)

+
    +

    +

  • Added support for large data transfers +

    +

  • XPAGet and XPASet now pass size_t instead of int for lengths +

    +

  • Send and receive callbacks now pass size_t instead of int for lengths +

    +

  • Port to mingw (Windows) +
+ + +

Public Release 2.1.14 (June 7, 2012)

+
    +

    +

  • Fixed several memory leaks in the Tcl wrappers (tcl.c). +

    +

  • Use Tcl stubs library for linking shared Tcl, if available. +
+ +

Public Release 2.1.13 (April 14, 2011)

+
    +

    +

  • An atexit handler is no longer installed automatically (it crashes +Tcl 8.5.8 applications). Call XPAAtExit(void) to install the handler. +

    +

  • Removed permission checking from Find() on cygwin systems. This was broken +by Windows 7. +

    +

  • Removed addition of -no-cpp-precomp flag from gcc 4.2 and beyond (Mac). +
+ +

Public Release 2.1.12 (January 26, 2010)

+
    +

    +

  • Added XPA_HOST environment variable to allow users to specify +the hostname (and hence, ip) component of the INET method id. This is +useful, for example, if you want to register an access point using a +VPN-generated IP instead of the canonical IP. +

    +

  • Fix typo in Tcl binding to xpainfo causing a crash after 2 invocations. +
+ +

Public Release 2.1.11 (December 7, 2009)

+
    +

    +

  • Generalized XPANSKeepAlive() to send messages to xpans, proxy xpans, or +both. The default is to send just to proxies (e.g. chandra-ed). +

    +

  • Changed XPANSKeepAlive() to send an in-band new-line char to +xpans, changed xpans to handle an in-band new-line as a keep-alive +message. Necessitated by Cisco routers that clear the URG flag in +a TCP packet, breaking OOB data transfer for the whole Internet, as +well as the OOB-based keep-alive implemented in xpans. +

    +

  • In xpans, print warning when the keep-alive option switch is used. +

    +

  • Port to mingw (thanks to B.Schoenhammer) +

    +

  • Change OOB character sent by xpans keepalive to a space, trying to working around cisco routers that force OOB data into the inbound stream. +

    +

  • fix gcc fprintf warning in xpans.c +
+ +

Public Release 2.1.10 (September 1, 2009)

+
    +

    +

  • Update mklib and configure.ac to support 64-bit builds on Macs. +

    +

  • Fixed bug in XPAAccess() in which the returned names could have an extra +(bogus) character when the target is an explicit ip:port or local socket file. +

    +

  • Add setjmp/longjmp support to xalloc. +

    +

  • Add XPASaveJmp(void *env) as a high-level interface to xalloc_savejmp(); +
+ +

Internal Release 2.1.9

+
    +

    +

  • Fixed a bug that prevented an access point starting with a number +from being recognized peoperly. NB: a pure number still signifies a +port on the current machine. Also num:num signifies ip:port, where ip +can be a pure hex value or the canonical form vvv.xxx.yyy.zzz. +

    +

  • Modified internal Launch() routine to use posix_spawn(), if necessary. +This is required for OS X 10.5 (leopard), which frowns upon use of fork() +and exec(). Also modified zprocess routines to use Launch(). +

    +

  • Added XPASetFree(xpa, void (*myfree)(void *)) routine to allow callbacks +to specify a free routine other than malloc free (e.g. Perl garbage collection). +

    +

  • XPACmdAdd() now checks to ensure that it was passed an XPA struct created +by XPACmdNew(). +

    +

  • Change launch.h to xlaunch.h to avoid conflict with OS X. +
+ +

Public Release 2.1.8 (1 November 2007)

+
    +

    +

  • A public release to complete current XPA development work. +
+ +

Patch Release 2.1.7b[1,2] (Feb 22, 2006; March 8, 2007)

+
    + +

    +

  • Added a convenience null to the end of the buffers returned by XPAGet. + +

    +

  • Added code to avoid calling atexit routine if a fork'ed child +calls exit() instead of _exit(). + +

    +

  • Added XPA_CLIENT_DOXPA environment variable to turn off client +processing of xpa server requests. + +

    +

  • Added --version to xpaset, xpaget, xpainfo, xpaaccess, xpans to +display XPA version and exit. + +

    +

  • Added support for integrating XPA into a Gtk loop. + +

    +

  • xpaaccess now returns its answer in the error code as well as to stdout +(without the -n switch, it returns 1 for a match, with the -n switch, +the number of matches is returned). + +

    +

  • Fixed bug which prevented xpans from being started up automatically +by an xpa server if its pathname contained a space character. + +

    +

  • Fixed bug in MINGW port of xpans in which an XPA server that +terminated via an interrupt was not being properly removed from the +list of registered access points. + +

    +

  • Added XPA_LOGNAME to override LOGNAME when registering username + +

    +

  • Upgraded swish-e indexing code to 2.4.5. + +
+ +

Patch Release 2.1.6 (4 May 2005)

+
    + +

    +

  • Added -P switch to xpans to enable experimental proxy support +(default is disabled). An argument of 1 processes proxy requests in +the same thread as xpans requests, while an argument of 2 processes +proxy requests in a separate thread. (The latter is recommended to +avoid xpans timeouts, since xpa callback processing can take a long +time.) + +

    +

  • Added ability to build shared libraries (done automatically with +configure --enable-shared) with compilers other than gcc. + +

    +

  • Made yet another attempt to build shared libraries under OS X. + +

    +

  • Fixed a server bug in Tcl support under Windows (introduced early +in 2.1.6) which caused an occasional SEGV. + +

    +

  • Fixed race condition in cases where 2 or more servers makes client calls +to one another. + +

    +

  • Fixed bug in the XPA handler routine in which an access point was +turned off if an error occurred in that routine (as opposed to the +user-defined callback routine). + +

    +

  • Fixed race condition when "ack=false" flag (or -n) is used with XPASet() +(or xpaset). + +

    +

  • Added defensive code to XPA handler to ensure that the passed XPA record +is valid. + +

    +

  • Tcl/XPA servers such as ds9 were not turning off select() on the +xpa channels inside an xpa callback, as required. This is now fixed. + +

    +

  • Added timestamps to most server and client error messages if the +XPA_TIMESTAMP_ERRORS variable is set. This is useful when XPA errors are +being logged in an error log (e.g. Web/CGI use). + +

    +

  • Generated PostScript and PDF versions of the help pages. + +

    +

  • Moved OPTIONS section before (often-lengthy) DESCRIPTION section in +man pages. + +

    +

  • All memory allocation now performs error checking on the result. + +

    +

  • Removed some compiler warnings that surfaced when using gcc -O2. + +

    +

  • Updated configure.ac to better support Tcl in Panther with Apple +Frameworks. + +
+ +

Patch Release 2.1.5 (12 January 2004)

+
    + +

    +

  • Fixed bug in XPAPoll(). Erroneously, no requests were being +processed when maxreq==0. Now, all pending events are processed, as +per the documentation. + +

    +

  • Added ack=false to XPAInfo() (and corresponding -n to xpainfo) +so that client does not wait for a response from the server. This is +essential in cases where XPA servers wish to send info messages to +one another without causing a race condition. + +

    +

  • Generated man pages from the html pages. These are installed +automatically at build time. + +

    +

  • The xpans program with Unix sockets now uses a lock file to signal +that it is running, in order to avoid a potential (but rare) race +condition at startup. + +

    +

  • Code that calls Unix-type bind() now manipulate umask() to ensure that +all users have write permissions to the socket file (OS X apparently uses +these permissions while previous platforms ignore them). + +

    +

  • Configure now checks for socklen_t type (OS X does not define it). + +

    +

  • Added an atexit function to run XPAFree. The aim here is to delete Unix +socket files on exiting. + +

    +

  • Under Windows, the Tcl event-handling code now blocks for 1/1000 of a +second instead of not blocking at all (which inadvertently used 100% of cpu). + +

    +

  • Upgraded Tcl/Tk support to 8.4. + +

    +

  • Made another round of checks was made through all instances of +strcat, strcpy, etc. to look for potential buffer overflows. Changed +all instances of sprintf() to snprintf(). + +

    +

  • Class and name designators are now limited to 1024 characters, for +no particular reason. + +

    +

  • The obsolete $SAORD_BIN variable was being added to the path when +searching for xpans. This is no longer the case. + +

    +

  • Fixed non-ANSI compiler errors in both xpa.c and xpans.c. + +

    +

  • Fixed minor problems to support compilation with g++. + +

    +

  • Ported to Intel icc and gcc 3.3 compilers. + +

    +

  • Upgraded autoconf to 2.57. Included in this upgrade is a change that +makes gcc the default compiler (use "configure CC=cc" to change this). +Also, by default, the Tcl shared object is no longer automatically built +if the Tcl libraries are used. Use the --enable-tclshlib switch in +configure to enable this feature. + +

    +

  • Changed license from public domain to GNU GPL. + +
+ +

Patch Release 2.1.4 (24 March 2003)

+
    + +

    +

  • Made inet method unique, even when hosts are behind a firewall using +the same ports (on different local machines). + +

    +

  • The initial connection from an xpa server to a local xpans now is +controlled by a timeout (default 5 sec, controlled by XPA_CONNECT_TIMEOUT +variable). This should prevent a hang on connect() if the network +is not set up correctly. + +

    +

  • Fixed rare race condition when an XPA server callback performed its own +XPAGet or XPASet call to another XPA server. + +

    +

  • Use POSIX O_NONBLOCK for non-blocking I/O in fcntl call if it +exists, instead of O_NDELAY. + +
+ +

Patch Release 2.1.3 (26 September 2002)

+
    + +

    +

  • Added -k [sec] switch to xpans to support sending one-byte keepalive +messages from xpans to registered xpa servers. + +

    +

  • Added XPANSKeepAlive routine (and Tcl equivalent) to allow +xpa servers to send a one-byte keepalive message to xpans. + +
+ +

Patch Release 2.1.2 (18 July 2002)

+
    + +

    +

  • The "-help" reserved command now also displays the XPA version, if +no explicit sub-commands are specified. + +

    +

  • Change internal state of xpans proxy to save ip:port value of a +server behind a NAT firewall. This is required to give some hope of +distinguishing multiple instances of ds9 running behind NAT. + +
+ +

Patch Release 2.1.1 (20 June 2002)

+
    + +

    +

  • Added a version check between xpans and an access point, +performed when it gets registered by an XPA server. If the server +has a version greater than the xpans version, a warning is issued by +both programs. + +

    +

  • Added a boolean XPA_NSREGISTER environment variable to allow an +XPA server to skip xpans registration. The default is to register with +the name server. If set to "false", the access point still is set up +but it is not registered with an xpans. It can be registered later on +(using -remote or -proxy, for example). + +

    +

  • Fixed bug in which xpans was still listening on any interface when +XPA_METHOD was localhost (instead of just listening on localhost). + +
+ +

Public Release 2.1.0 (22 April 2002)

+ +

+New features include: + +

    +

    +

  • Support for proxy access to XPA servers (e.g. ds9) situated +behind a firewall (useful for NVO-type applications). + +

    +

  • Improved support for allowing remote machines access rights to the +XPA access points (useful for NVO-type applications). + +

    +

  • Ability for XPAAccess() routine and xpaaccess program to contact XPA + directly. + +

    +

  • Support for a clipboard access point that allows clients to store ASCII +state information in an XPA-enabled server. + +

    +

  • Improved support for Windows platform, as well as new support for Mac OSX. +
+ +

Pre-Release 2.1.0e (2 April 2002)

+
    + +

    +

  • Removed the environment variable generated by each XPA access +point (of the form XPA_name=method). The putenv() call was causing ds9 +to crash under both Linux and LinuxPPC during a socket operation. We +suspect a bug in putenv but cannot prove it and this feature is not +essential, so ... + +
+ +

Pre-Release 2.1.0e (1 April 2002)

+
    + +

    +

  • Fixed an uninitialized variable in xpamb which prevented it from +working at all on some systems. + +

    +

  • Changed xpamb switch from "-add" to "-data" (to store named data). + +

    +

  • Changed how xpamb works with xpaget so that xpamb can return data +from XPA access points as well as from stored data. (Previous versions +only returned stored data.) Now, you can retrieve stored data +explicitly using the -info and/or -data switches. For example: +
    +  xpaget xpamb -info foo
+
    +will return info about the previously stored data named foo. If +neither switch is present, then the name is assumed to be an XPA access +point. +
+ +

Pre-Release 2.1.0e (25 March 2002)

+
    + +

    +

  • Changed symbol for default port from "*" to "$port" to avoid +a syntactical conflict between class:* and machine:* when processing an +XPA access point class:name specification. Thus, the default inet +method now is '$host:$port' instead of '$host:*'. + +
+ +

Pre-Release 2.1.0e (19 March 2002)

+
    + +

    +

  • Removed timeout check when reading data (in clients using xpaget +and servers filling the data buffer). We have more and more cases +where we need to wait a long time to retrieve data (e.g., slow +networks or receiving data being compressed on the fly). + +

    +

  • Moved call to sigaction(SIGCHLD,...) out of XPAOpen(), so that it +is only executed when needed by XPAGet()/XPASet() routines called from +within xpans/proxy. But then changed logic to use a double fork() instead +of sigaction() to prevent zombies (Stevens Adv. Programming p 202). + +

    +

  • Each XPA access point now generates an environment variable of the +form XPA_name=method so that children can communicate with the parent access +point more easily. + +

    +

  • Added version option to Tcl xparec: +
    +  if [catch { xparec "" version } version] {
+    puts "pre-2.1.0e"
+  } else {
+    puts [split $version .]
+  }
+
    +to help differentiate between XPA versions within Tcl code. + +
+ +

Pre-Release 2.1.0e (14 February 2002)

+
    +

    +

  • Fixed client handling of out-of-sync messages. +
+ +

Pre-Release 2.1.0e (11 February 2002)

+
    + +

    +

  • Fixed client.c/xopen() so that it does not open an extra socket. + +

    +

  • Fixed xpainfo/xopen() to prevent client from hanging waiting for ack. + +

    +

  • Modified stest to generate xpaaccess points xpa, xpa1, c_xpa, and +i_xpa (or more generally, , 1, c_, i) to allow +more flexible testing of templates. Also added -a for testing XPAAccess(). + +
+ +

Beta Release 2.1.0b10 (31 January 2002)

+
    + +

    +

  • Added support for Mac OSX/Darwin to configure file. + +
+ +

Beta Release 2.1.0b9 (26 January 2002)

+
    + +

    +

  • Fixed bug in client library that caused XPAAccess() call to hang. + +
+ +

Beta Release 2.1.0b8 (4 January 2002)

+
    + +

    +

  • Made modifications to Makefile.in to make releases easier. + +

    +

  • Added instructions to Makefile.in so that xpa.h will always have +correct #defines for XPA_VERSION, XPA_MAJOR_VERSION, XPA_MINOR_VERSION, +and XPA_PATCH_LEVEL. + +
+ +

Beta Release 2.1.0b7 (21 December 2001)

+
    + +

    +

  • Added -proxy switch to -remote sub-command to allow remote access +through a firewall, using xpans as a proxy server. The support for proxy +processing required a change to the client/server protocol. This means +that new xpa servers will not work with old xpa clients (although new +xpa clients will work with old xpa servers). For details about proxy +firewall support, see http://hea-www.harvard.edu/RD/xpa/inet.html. + +

    +

  • Fixed Tcl support for XPA under Windows/Cygwin by re-writing +the code used to add XPA to the Tcl event loop. This fix makes ds9 +support for XPA much more stable under Windows. + +

    +

  • Added the shutdown() call to XPA under Cygwin/Windows before +closing send() sockets. It appears that a Cygwin recv() socket call +does not always sense when the other end closes the socket using +close(). This measure must be considered a hack, since the actual +problem was never resolved. + +

    +

  • Added code to protect accept() and select() calls from interrupts. + +

    +

  • Extended syntax of the environment variable XPA_NSINET to: +
    +  setenv XPA_NSINET host:port[,port[,port]]
+
    +to allow specification of the XPA access point port for xpans, +as well as the proxy data port. + +

    +

  • Modified xpans log file so that it contains the xpaset commands +required to reconnect with xpa servers. + +

    +

  • xpans now deletes its Unix socket files. + +
+ +

Beta Release 2.1.0b6 (29 October 2001)

+
    + +

    +

  • Implemented a reserve public access point named -clipboard so +that clients can store ASCII state information on any number of named +clipboards. Clipboards of the same name created by clients on +different machines are kept separate. The syntax for creating a +clipboard is: +
    +  [data] | xpaset [server] -clipboard add|append [clipboard_name]
+  xpaset -p [server] -clipboard delete [clipboard_name]
+  xpaget [server] -clipboard [clipboard_name]
+
    +Use "add" to create a new clipboard or replace the contents of an existing +one. Use "append" to append to an existing clipboard. + +
+ +

Beta Release 2.1.0b5 (22 October 2001)

+
    + +

    +

  • Use FD_SETSIZE instead of getdtablesize() to determine how many files +to check during select(); + +

    +

  • Under Cygwin, the launch() routine now uses the Cygwin spawnvp() +instead of fork()/exec() where possible (i.e., if no stdfiles are +being redirected). This is recommended by Cygwin's (skimpy) on-line +documentation and seems to fix the problems ds9 had when starting xpans +automatically. + +

    +

  • Added error check to select() call in xpans. + +
+ +

Beta Release 2.1.0b4 (24 September 2001)

+
    + +

    +

  • The launch() now can return an error code if the execv() system +call fails (something system() does not do). + +

    +

  • INET socket calls between xpa clients and servers now will use +localhost if they are on the same machine. This protects against +Linux systems where the hostname is hardwired (wrongly) in a DHCP +environment. + +
+ +

Beta Release 2.1.0b3 (6 September 2001)

+
    + +

    +

  • Modified xpans so that, in the case of a firewall, it tries to +correct the specified ip:port by matching against the ip found in +the socket packet at accept() time. + +

    +

  • Replaced system() call used to start xpans automatically with +a special launch() call, which performs execvp() directly without going +through sh. (launch() works under DOS and has fewer security problems.) + +

    +

  • Fixed bug in xpans in which its xpa port was always being set to 14286. + +
+ +

Beta Release 2.1.0b2 (17 August 2001)

+
    + +

    +

  • Added support for -remote command, which registers the access +point in the XPA name server of the specified remote server, and gives +the remote server access rights to the access point. This is used, for +example, to give data servers xpa access to ds9 so that data can be +sent to ds9 as a result of a CGI-based Web query. + +

    +

  • Reserved commands (except "-help" and "-version") now can only be +executed on the machine on which the xpa service is running (not +through -remote servers). + +

    +

  • Fixed bug in xpans in which a bad telnet command could hang the program. + +

    +

  • Added -s [security file] to xpans to allow logging of all external +connections. + +
+ +

Beta Release 2.1.0b1 (6 August 2001)

+
    +

    +

  • The xpaaccess client program and XPAAccess() client subroutine +were modified so that an access-type query can directly contact the +xpa servers matching the requested xpa template, instead of just +querying the name server for registered access points. This avoid the +race condition in which an access point is registered but is not yet +available, perhaps because the server has not yet entered its event +loop. Note that the calling sequence of the XPAAccess() routine was +changed to return all matching access points and their availability +status (instead of just returning the number of registered access +points). Because of this, we are calling this a minor release instead +of a patch. + +

    +

  • Added support for XPA_PORT and XPA_PORTFILE environment variables +to allow specification of the port to be used by the command channel +(and data channel, if an optional second port is specified) for a given +access point. + +

    +

  • Added -m switch to xpaget, xpaset, xpainfo, xpaaccess to allow +override of the XPA_METHOD environment variable. + +

    +

  • Changed the default name of the ACL file from xpa.acl to acls.xpa. + +

    +

  • Fixed bug in which it was not possible to send a "set ACL" +command to an XPA server which did not have a receive callback (i.e., +did not allow xpaset). The xpans program is one such server. It now is +possible to set the ACL on xpans. + +

    +

  • We have discovered that Tcl support for datachan and cmdchan is +broken under Windows due to an unexplained incompatibility between +Cygwin sockets and Win32 sockets. We therefore have removed datachan +and cmdchan from the Windows/Tcl support until further notice. + +

    +

  • Extended the behavior of the XPA_DEFACL environment variable so that +it can support more than one acl, using a list of semi-colon delimited +controls such as: setenv XPA_DEFACL '*:* $host +; *:foo1 otherhost +'. + +

    +

  • Fixed bug in which the class:name specifier "*:*" was erroneously +trying to access the xpans name server, instead of accessing all +access points. + +

    +

  • Support TMPDIR and TMP environment variables as well as XPA_TMPDIR. + +
+ +

Patch Release 2.0.5 (10 November 2000)

+
    +

    +

  • Added support for Tcl on Windows where there is no select()-based +event loop (i.e., where there is no Tcl_CreateFileHandler call in Tcl) +

    +

  • Minor fixes in Makefile for installing on Windows +

    +

  • Minor compiler fixes from gcc -Wall. +
+ +

Patch Release 2.0.4 (20 September 2000)

+
    +

    +

  • Removed extraneous include of varargs.h from find.c. +

    +

  • Ported to SGI C compiler, which caught lots of unused variables, etc. +

    +

  • Ported to Cygwin/Windows, which required that we change socket read() +and write() calls to recv() and send() respectively. Also had to ensure that +we only did socket I/O on sockets (no fileio). +
+ +

Patch Release 2.0.3 (15 June 2000)

+
    +

    +

  • Fixed the client XPASet() and XPASetFd() calls to handle the specified +max number of connections (they were ignoring this argument, leading to +memory overwrites). +

    +

  • Fixed Makefile.in so that CFLAGS and LDFLAGS are not hard-wired values. +

    +

  • Fixed word.h to load malloc.h and stdlib.h only if they exist. +

    +

  • Documentation fixes to programs.html (in xpaaccess) and client.html +(XPANSLookup). +

    +

  • Added explicit typecast to strlen() argument to MAX #define in +XPAClientStart (strlen() is unsigned in Linux, which can break MAX). +

    +

  • Removed bogus Imakefile from directory. +

    +

  • Changed directory name to include patch level (i.e., xpa-2.0.3). +
+ +

Patch Release 2.0.2 (9 September 1999)

+
    +

    +

  • Fixed server mode (-s) in the xpaset program by properly cleaning up +the input buffers (sending commands and data in server mode was broken). +
+ +

Patch Release 2.0.1 (6 August 1999)

+
    +

    +

  • Fixed the Tcl binding code (tcl.c) for 64-bit machines (Dec Alpha) +(erroneously used %x instead of %p when converting pointers to ASCII). +

    +

  • Got rid of a few compiler warnings on 64-bit machines (a few are +unavoidable since we must cast int to void * and back when passing around +client data). +
+ +

Public Release 2.0 (27 May 1999)

+
    +

    +

  • "a new day with no mistakes ... yet" +
+ +

XPA Changes: Changes For Users from XPA 1.0 and 2.0

+ + +

Summary

+

+This document describes changes that will affect users who migrate +from XPA 1.0 to XPA 2.0. + + +

Description

+

+There have been a few changes that affect users who upgrade XPA +from version 1.0 to version 2.0. These changes are detailed below. +

    +

    +

  • XPA commands no longer have a resolver routine (this is open to +negotiations, but we decided the idea was dumb). For the SAOtng +program, this means that you must explicitly specify the access +point, i.e.,: +
    +  cat foo.fits | xpaset SAOtng fits
+
    + +

    +instead of: +

    +  cat foo.fits | xpaset SAOtng
+
    +

    +

  • By default, xpaset, xpaget, etc. now wait for the server callback to +complete; i.e., the old -W is implied (and the switch is ignored). +This allows support for better error handling. If you want xpaset, etc. +to return before the callback is complete, use -n switch: +
    +  echo "file foo.fits" | xpaset -n SAOtng
+
    +

    +

  • The old -w switch in xpaset and xpaget is no longer necessary (and is +ignored), since you can have more than one process communicating with +an xpa access point at one time. + +

    +

  • The new -p switch on xpaset means you need not read from stdout: +
                  
+  xpaset -p SAOtng colormap I8
+
    +

    +will send the paramlist to the SAOtng callback without reading from stdin. + +

+ + + + + +

XPAClient: The XPA Client-side Programming Interface

Summary

+A description of the XPA client-side programming interface. + + +

Introduction to XPA Client Programming

+

+Sending/receiving data to/from an XPA access point is easy: you +generally only need to call the XPAGet() or XPASet() subroutines. +

+  #include <xpa.h>
+
+  int XPAGet(XPA xpa,
+      char *template, char *paramlist, char *mode,
+      char **bufs, size_t *lens, char **names, char **messages, int n);
+
+  int XPASet(XPA xpa,
+      char *template, char *paramlist, char *mode,
+      char *buf, size_t len, char **names, char **messages, int n);
+
+  int XPAInfo(XPA xpa,

+      char ***classes, char ***names, char ***methods, char ***infos);
+
+ +

Introduction

+ +To use the XPA application programming interface, a software developer +generally will include the xpa.h definitions file: +
+  #include <xpa.h>
+
+in the software module that defines or accesses an XPA access point and +then will link against the libxpa.a library: +
+  gcc -o foo foo.c libxpa.a
+
+XPA has been compiled using both C and C++ compilers. +

+Client communication with XPA public access points generally is +accomplished using XPAGet() or XPASet() within a program (or xpaget +and xpaset at the command line). Both routines require specification +of the name of the access point. If a template +is used to specify the access point name (e.g., "ds9*"), then +communication will take place with all servers matching that template. + + + + +

XPAGet: retrieve data from one or more XPA servers

+ + + +
+  #include <xpa.h>
+
+  int XPAGet(XPA xpa,
+             char *template, char *paramlist, char *mode,
+             char **bufs, size_t *lens, char **names, char **messages,
+	     int n);
+
+ + + +

+Retrieve data from one or more XPA servers whose class:name identifier +matches the specified template. + +

+A +template +of the form "class1:name1" is sent to the +XPA name server, which returns a list of at most n matching XPA +servers. A connection is established with each of these servers and +the paramlist string is passed to the server as the data transfer +request is initiated. If an XPA struct is passed to the call, then the +persistent connections are updated as described above. Otherwise, +temporary connections are made to the servers (which will be closed +when the call completes). + +

+The XPAGet() routine then retrieves data from at most n XPA servers, +places these data into n allocated buffers and places the buffer +pointers in the bufs array. The length of each buffer is stored in the +lens array. A string containing the class:name and ip:port is stored +in the name array. If a given server returned an error or the server +callback sends a message back to the client, then the message will be +stored in the associated element of the messages array. NB: if +specified, the name and messages arrays must be of size n or greater. + +

+The returned message string will be of the form: +

+  XPA$ERROR error-message (class:name ip:port)
+
+or +
+  XPA$MESSAGE message (class:name ip:port)
+
+

+Note that when there is an error stored in an messages entry, the +corresponding bufs and lens entry may or may not be NULL and 0 +(respectively), depending on the particularities of the server. + +

+The return value will contain the actual number of servers that were +processed. This value thus will hold the number of valid entries in +the bufs, lens, names, and messages arrays, and can be used to loop +through these arrays. In names and/or messages is NULL, no information is +passed back in that array. + +

+The bufs, names, and messages arrays should be freed upon completion (if +they are not NULL); + +

+The mode string is of the form: "key1=value1,key2=value2,..." +The following keywords are recognized: +

+  key   	value		default		explanation
+  ------	--------	--------	-----------
+  ack		true/false	true		if false, don't wait for ack from server (after callback completes)
+  doxpa		true/false	true		client processes xpa requests
+
+

+The ack keyword is not very useful, since the server completes the callback +in order to return the data anyway. It is here for completion (and perhaps +for future usefulness). + +

+Normally, an XPA client will process incoming XPA server requests +while awaiting the completion of the client request. Setting this +variable to "false" will prevent XPA server requests from being +processed by the client. + +

+Example: +

+  #include <xpa.h>
+
+  #define NXPA 10
+  int  i, got;
+  size_t  lens[NXPA];
+  char *bufs[NXPA];
+  char *names[NXPA];
+  char *messages[NXPA];
+  got = XPAGet(NULL, "ds9", "file", NULL, bufs, lens, names, messages,
+  NXPA);
+  for(i=0; i<got; i++){
+    if( messages[i] == NULL ){
+      /* process buf contents */
+      ProcessImage(bufs[i], ...);
+      free(bufs[i]);
+    }
+    else{
+      /* error processing */
+      fprintf(stderr, "ERROR: %s (%s)\n", messages[i], names[i]);
+    }
+    if( names[i] )
+      free(names[i]);
+    if( messages[i] )
+      free(messages[i]);
+  }
+
+ + + + +

XPASet: send data to one or more XPA servers

+ + + +
+  #include <xpa.h>
+
+  int XPASet(XPA xpa,
+             char *template, char *paramlist, char *mode,
+             char *buf, size_t len, char **names, char **messages,
+             int n);
+
+ + + +

+Send data to one or more XPA servers whose class:name identifier +matches the specified template. + +

+A +template +of the form "class1:name1" is sent to the +XPA name server, which returns a list of at most n matching XPA +servers. A connection is established with each of these servers and +the paramlist string is passed to the server as the data transfer +request is initiated. If an XPA struct is passed to the call, the +persistent connections are updated as described above. Otherwise, +temporary connections are made to the servers (which will be closed +when the call completes). + +

+The XPASet() routine transfers data from buf to the XPA servers. +The length of buf (in bytes) should be placed in the len variable. + +

+A string containing the class:name and ip:port of each of these server +is returned in the name array. If a given server returned an error or +the server callback sends a message back to the client, then the +message will be stored in the associated element of the messages +array. NB: if specified, the name and messages arrays must be of size +n or greater. + +

+The returned message string will be of the form: + +

+  XPA$ERROR   [error] (class:name ip:port)
+
+or +
+  XPA$MESSAGE [message] (class:name ip:port)
+
+

+The return value will contain the actual number of servers that were +processed. This value thus will hold the number of valid entries in +the names and messages arrays, and can be used to loop through these +arrays. In names and/or messages is NULL, no information is passed back +in that particular array. + +

+The mode string is of the form: "key1=value1,key2=value2,..." +The following keywords are recognized: +

+  key   	value		default		explanation
+  ------	--------	--------	-----------
+  ack		true/false	true		if false, don't wait for ack from server (after callback completes)
+  verify	true/false	false		send buf from XPASet[Fd] to stdout
+  doxpa		true/false	true		client processes xpa requests
+
+

+The ack keyword is useful in cases where one does not want to wait for +the server to complete, e.g. if a lot of processing needs to be done +by the server on the passed data or when the success of the server +operation is not relevant to the client. + +

+Normally, an XPA client will process incoming XPA server requests +while awaiting the completion of the client request. Setting this +variable to "false" will prevent XPA server requests from being +processed by the client. + +

+Example: +

+  #include <xpa.h>
+
+  #define NXPA 10
+  int  i, got;
+  size_t  len;
+  char *buf;
+  char *names[NXPA];
+  char *messages[NXPA];
+  ...
+  [fill buf with data and set len to the length, in bytes, of the data]
+  ...
+  /* send data to all access points */
+  got = XPASet(NULL, "ds9", "fits", NULL, buf, len, names, messages, NXPA);
+  /* error processing */
+  for(i=0; i<got; i++){
+    if( messages[i] ){
+      fprintf(stderr, "ERROR: %s (%s)\n", messages[i], names[i]);
+    }
+    if( names[i] )    free(names[i]);
+    if( messages[i] ) free(messages[i]);
+  }
+
+ + + + +

XPAInfo: send short message to one or more XPA servers

+ + + +
+  #include <xpa.h>
+
+  int XPAInfo(XPA xpa,
+              char *template, char *paramlist, char *mode,
+	      char **names, char **messages, int n);
+
+ + + +

+Send a short paramlist message to one or more XPA servers whose +class:name identifier matches the specified +template. + +

+A +template +of the form "class1:name1" is sent to the +XPA name server, which returns a list of at most n matching XPA +servers. A connection is established with each of these servers and +the paramlist string is passed to the server as the data transfer +request is initiated. If an XPA struct is passed to the call, then the +persistent connections are updated as described above. Otherwise, +temporary connections are made to the servers (which will be closed +when the call completes). + +

+The XPAInfo() routine does not send data from a buf to the XPA +servers. Only the paramlist is sent. The semantics of the paramlist +is not formalized, but at a minimum is should tell the server how to +get more information. For example, it might contain the class:name +of the XPA access point from which the server (acting as a client) +can obtain more info using XPAGet. + +

+A string containing the class:name and ip:port of each server is +returned in the name array. If a given server returned an error or +the server callback sends a message back to the client, then the +message will be stored in the associated element of the messages +array. The returned message string will be of the form: +

+  XPA$ERROR   error-message (class:name ip:port)
+
+or +
+  XPA$MESSAGE message 	  (class:name ip:port)
+
+

+The return value will contain the actual number of servers that were +processed. This value thus will hold the number of valid entries in +the names and messages arrays, and can be used to loop through these +arrays. In names and/or messages is NULL, no information is passed back +in that array. + +

+The following keywords are recognized: +

+  key   	value		default		explanation
+  ------	--------	--------	-----------
+  ack		true/false	true		if false, don't wait for ack from server
+
+

+When ack is false, XPAInfo() will not wait for an error return from the XPA +server. This means, in effect, that XPAInfo will send its paramlist string +to the XPA server and then exit: no information will be sent from the server +to the client. This UDP-like behavior is essential to avoid race +conditions in cases where XPA servers are sending info messages to +other servers. If two servers try to send each other an info message +at the same time and then wait for an ack, a race condition will result and +one or both will time out. + +

+Example: +

+  (void)XPAInfo(NULL, "IMAGE", "ds9 image", NULL, NULL, NULL, 0);
+
+ + + + +

XPAGetFd: retrieve data from one or more XPA servers and write to files

+ + + +
+  #include <xpa.h>
+
+  int XPAGetFd(XPA xpa,
+               char *template, char *paramlist, char *mode,
+	       int *fds, char **names, char **messages, int n);
+
+ + + +

+Retrieve data from one or more XPA servers whose class:name identifier +matches the specified +template +and write it to files associated with +one or more standard I/O fds (i.e, handles returned by open()). + +

+A +template +of the form "class1:name1" is sent to the +XPA name server, which returns a list of at most ABS(n) matching XPA +servers. A connection is established with each of these servers and +the paramlist string is passed to the server as the data transfer +request is initiated. If an XPA struct is passed to the call, then the +persistent connections are updated as described above. Otherwise, +temporary connections are made to the servers (which will be closed +when the call completes). + +

+The XPAGetFd() routine then retrieves data from the XPA servers, +and write these data to the fds associated with one or more fds +(i.e., results from open). Is n is positive, then there will be n fds +and the data from each server will be sent to a separate fd. If n is +negative, then there is only 1 fd and all data is sent to this single +fd. (The latter is how xpaget is implemented.) + +

+A string containing the class:name and ip:port is stored in the name +array. If a given server returned an error or the server callback +sends a message back to the client, then the message will be stored in +the associated element of the messages array. NB: if specified, the +name and messages arrays must be of size n or greater. + +

+The returned message string will be of the form: +

+  XPA$ERROR   error-message (class:name ip:port)
+
+or +
+  XPA$MESSAGE message 	  (class:name ip:port)
+
+

+Note that when there is an error stored in an messages entry, the +corresponding bufs and lens entry may or may not be NULL and 0 +(respectively), depending on the particularities of the server. + +

+The return value will contain the actual number of servers that were +processed. This value thus will hold the number of valid entries in +the bufs, lens, names, and messages arrays, and can be used to loop +through these arrays. In names and/or messages is NULL, no information is +passed back in that array. + +

+The mode string is of the form: "key1=value1,key2=value2,..." +The following keywords are recognized: +

+  key   	value		default		explanation
+  ------	--------	--------	-----------
+  ack		true/false	true		if false, don't wait for ack from server (after callback completes)
+
+

+The ack keyword is not very useful, since the server completes the callback +in order to return the data anyway. It is here for completion (and perhaps +for future usefulness). + +

+Example: +

+  #include <xpa.h>
+  #define NXPA 10
+  int  i, got;
+  int fds[NXPA];
+  char *names[NXPA];
+  char *messages[NXPA];
+  for(i=0; i<NXPA; i++)
+    fds[i] = open(...);
+  got = XPAGetFd(NULL, "ds9", "file", NULL, fds, names, messages, NXPA);
+  for(i=0; i<got; i++){
+    if( messages[i] != NULL ){
+      /* error processing */
+      fprintf(stderr, "ERROR: %s (%s)\n", messages[i], names[i]);
+    }
+    if( names[i] )
+      free(names[i]);
+    if( messages[i] )
+      free(messages[i]);
+  }
+
+ + + + +

XPASetFd: send data from stdin to one or more XPA servers

+ + + +
+  #include <xpa.h>
+
+  int XPASetFd(XPA xpa,
+               char *template, char *paramlist, char *mode,
+	       int fd, char **names, char **messages, int n)
+
+ + + +

+Read data from a standard I/O fd and send it to one or more XPA +servers whose class:name identifier matches the specified +template. + +

+A +template +of the form "class1:name1" is sent to the +XPA name server, which returns a list of at most n matching XPA +servers. A connection is established with each of these servers and +the paramlist string is passed to the server as the data transfer +request is initiated. If an XPA struct is passed to the call, then the +persistent connections are updated as described above. Otherwise, +temporary connections are made to the servers (which will be closed +when the call completes). + +

+The XPASetFd() routine then reads bytes from the specified fd +until EOF and sends these bytes to the XPA servers. +The final parameter n specifies the maximum number of servers to contact. +A string containing the class:name and ip:port of each server is returned in +the name array. If a given server returned an error, then the error +message will be stored in the associated element of the messages array. +NB: if specified, the name and messages arrays must be of size n or greater. + +

+The return value will contain the actual number of servers that were +processed. This value thus will hold the number of valid entries in +the names and messages arrays, and can be used to loop through these +arrays. In names and/or messages is NULL, no information is passed back +in that array. + +

+The mode string is of the form: "key1=value1,key2=value2,..." +The following keywords are recognized: +

+  key   	value		default		explanation
+  ------	--------	--------	-----------
+  ack		true/false	true		if false, don't wait for ack from server (after callback completes)
+  verify	true/false	false		send buf from XPASet[Fd] to stdout
+
+

+The ack keyword is useful in cases where one does not want to wait for +the server to complete, e.g. is a lot of processing needs to be done +on the passed data or when the success of the server operation is not +relevant to the client. + +

+Example: +

+  #include <xpa.h>
+
+  #define NXPA 10
+  int  i, got;
+  int fd;
+  char *names[NXPA];
+  char *messages[NXPA];
+  fd = open(...);
+  got = XPASetFd(NULL, "ds9", "fits", NULL, fd, names, messages, NXPA);
+  for(i=0; i<got; i++){
+    if( messages[i] != NULL ){
+      /* error processing */
+      fprintf(stderr, "ERROR: %s (%s)\n", messages[i], names[i]);
+    }
+    if( names[i] )
+      free(names[i]);
+    if( messages[i] )
+      free(messages[i]);
+  }
+
+ + + + +

XPAOpen: allocate a persistent client handle

+ + + +
+  #include <xpa.h>
+
+  XPA XPAOpen(char *mode);
+
+ + + +

+XPAOpen() allocates a persistent XPA struct that can be used with +calls to XPAGet(), XPASet(), XPAInfo(), XPAGetFd(), and +XPASetFd(). Persistence means that a connection to an XPA server is +not closed when one of the above calls is completed but will be +re-used on successive calls. Using XPAOpen() therefore saves the time +it takes to connect to a server, which could be significant with slow +connections or if there will be a large number of exchanges with a +given access point. The mode argument currently is ignored ("reserved +for future use"). + +

+An XPA struct is returned if XPAOpen() was successful; otherwise NULL +is returned. This returned struct can be passed as the first argument +to XPAGet(), etc. Those calls will update the list of active XPA +connections. Already connected servers (from a previous call) are +left connected and new servers also will be connected. Old servers +(from a previous call) that are no longer needed are disconnected. +The connected servers will remain connected when the next call to +XPAGet() is made and connections are once again updated. + +

+Example: +

+ #include <xpa.h>
+
+  XPA xpa;
+  xpa = XPAOpen(NULL);
+
+ + + + +

XPAClose: close a persistent XPA client handle

+ + + +
+  #include <xpa.h>
+
+  void XPAClose(XPA xpa);
+
+ + + +

+XPAClose closes the persistent connections associated with this XPA struct +and frees all allocated space. It also closes the open sockets connections +to all XPA servers that were opened using this handle. + +

+Example: +

+  #include <xpa.h>
+
+  XPA xpa;
+  XPAClose(xpa);
+
+ + + + +

XPANSLookup: lookup registered XPA access points

+ + + +
+  #include <xpa.h>
+
+  int XPANSLookup(XPA xpa,
+  	          char *template, char type,
+	          char ***classes, char ***names,
+	          char ***methods, char ***infos)
+
+ + + +

+XPA routines act on a class:name identifier in such a way +that all access points that match the identifier are processed. It is +sometimes desirable to choose specific access points from the +candidates that match the +template. In order to do this, the +XPANSLookup routine can be called to return a list of matches, so that +specific class:name instances can then be fed to XPAGet(), XPASet(), etc. + +

The first argument is an optional XPA struct. If non-NULL, the +existing name server connection associated with the specified xpa is +used to query the xpans name server for matching templates. Otherwise, +a new (temporary) connection is established with the name server. + +

+The second argument to XPANSLookup is the class:name +template +to match. + +

+The third argument for XPANSLookup() is the type of access and can be +any combination of: +

+  type   	explanation
+  ------	-----------
+  g		xpaget calls can be made on this access point
+  s		xpaset calls can be made on this access point
+  i		xpainfo calls can be made on this access point
+
+

+The call typically specifies only one of these at a time. + +

+The final arguments are pointers to arrays that will be filled +in and returned by the name server. The name server will allocate and +return arrays filled with the classes, names, and methods of all XPA +access points that match the template +and have the specified type. Also returned are info strings, which +generally are used internally by the client routines. These can be +ignored (but the strings must be freed). The function returns the +number of matches. The returned value can be used to loop through the +matches: + +Example: +

+  #include <xpa.h>
+
+  char **classes;
+  char **names;
+  char **methods;
+  char **infos;
+  int i, n;
+  n = XPANSLookup(NULL, "foo*", "g", &classes, &names, &methods, &infos);
+  for(i=0; i<n; i++){
+    [more specific checks on possibilities ...]
+    [perhaps a call to XPAGet for those that pass, etc. ...]
+    /* don't forget to free alloc'ed strings when done */
+    free(classes[i]);
+    free(names[i]);
+    free(methods[i]);
+    free(infos[i]);
+  }
+  /* free up arrays alloc'ed by names server */
+  if( n > 0 ){
+    free(classes);
+    free(names);
+    free(methods);
+    free(infos);
+  }
+
+

+The specified +template +also can be a host:port specification, for example: +

+  myhost:12345
+
+

+In this case, no connection is made to the name server. Instead, the +call will return one entry such that the ip array contains the ip for +the specified host and the port array contains the port. The class +and name entries are set to the character "?", since the class and +name of the access point are not known. + + + + +

XPAAccess: return XPA access points matching +template (XPA 2.1 and above)

+ + + +
+  #include <xpa.h>
+
+  int XPAAccess(XPA xpa,
+	        char *template, char *paramlist, char *mode,
+	        char **names, char **messages, int n);
+
+ + + +

+The XPAAccess routine returns the public access points that match the +specified second argument template and +have the specified access type. + +

+A +template +of the form "class1:name1" is sent to the +XPA name server, which returns a list of at most n matching XPA +servers. A connection is established with each of these servers and +the paramlist string is passed to the server as the data transfer +request is initiated. If an XPA struct is passed to the call, then the +persistent connections are updated as described above. Otherwise, +temporary connections are made to the servers (which will be closed +when the call completes). + +

+The XPAAccess() routine retrieves names from at most n XPA servers +that match the specified template and that were checked for access +using the specified mode. The return string contains both the +class:name and ip:port. If a given server returned an error or the +server callback sends a message back to the client, then the message +will be stored in the associated element of the messages array. +NB: if specified, the name and messages arrays must be of size n or greater. + +

+The returned message string will be of the form: +

+  XPA$ERROR error-message (class:name ip:port)
+
+

+Note that names of matching registered access points are always +returned but may not be valid; it is not sufficient to assume that the +returned number of access points is the number of valid access points. +Rather, it is essential to check the messages array for error +messages. Any string in the messages array is an error message and +indicated that the associated access point is not available. + +

+For example, assume that a server registers a number of access points +but delays entering its event loop. If a call to XPAAccess() is made +before the event loop is entered, the call will timeout (after waiting +for the long timeout period) and return an error of the form: +

+  XPA$ERROR: timeout waiting for server authentication (XPA:xpa1)
+
+The error means that the XPA access point has been registered but is +not yet available (because events are not being processed). When the +server finally enters its event loop, subsequent calls to XPAAccess() +will return successfully. + +

+NB: This routine only works with XPA servers built with XPA 2.1.x and later. +Servers with older versions of XPA will return the error message: + + XPA$ERROR invalid xpa command in initialization string + +If you get this error message, then the old server actually is ready +for access, since it got to the point of fielding the query! The +xpaaccess program, for example, ignores this message in order to work +properly with older servers. + +

+The third argument for XPAAccess() is the type of access and can be +any combination of: +

+  type   	explanation
+  ------	-----------
+  g		xpaget calls can be made on this access point
+  s		xpaset calls can be made on this access point
+  i		xpainfo calls can be made on this access point
+
+

+The mode string argument is of the form: "key1=value1,key2=value2,..." +The following keywords are recognized: +

+  key   	value		default		explanation
+  ------	--------	--------	-----------
+  ack		true/false	true		if false, don't wait for ack from server (after callback completes)
+
+

+The ack keyword is not very useful, since the server completes the callback +in order to return the data anyway. It is here for completion (and perhaps +for future usefulness). + + + + + + + + + + + + + + + + + + + + + + + +

XPAConvert: Converting the XPA API to 2.0

+ + +

Summary

+

+This document describes tips for converting from xpa 1.0 (Xt-based +xpa) to xpa 2.0 (socket-based xpa). + + +

Description

+

+The following are tips for converting from xpa 1.0 (Xt-based xpa) to +xpa 2.0 (socket-based xpa). The changes are straight-forward and +almost can be done automatically (we used editor macros for most of +the conversion). +

    +

    +

  • The existence of the cpp XPA_VERSION directive to distinguish between 1.0 +(where it is not defined) and 2.0 (where it is defined). + +

    +

  • Remove the first widget argument from all send and receive server +callbacks. Also change first 2 arguments from XtPointer to void +*. For example: +
    +#ifdef XPA_VERSION
+static void XPAReceiveFile(client_data, call_data, paramlist, buf, len)
+     void *client_data;
+     void *call_data;
+     char *paramlist;
+     char *buf;
+     int len;
+#else
+static void XPAReceiveFile(w, client_data, call_data, paramlist, buf, len)
+     Widget w;
+     XtPointer client_data;
+     XtPointer call_data;
+     char *paramlist;
+     char *buf;
+     int len;
+#endif
+
    +

    +

  • Server callbacks should be declared as returning int instead +of void. They now should return 0 for no errors, -1 for error. + +

    +

  • The mode flags have changed when defining XPA server callbacks. +The old S flag (save buffer) is replaced by freebuf=false. +The old E flag (empty buffer is OK) is no longer used (it +was an artifact of the X implementation). + +

    +

  • Change NewXPACommand() to XPAcmdNew(), with the new calling sequence: +
    +  xpa = NewXPACommand(toplevel, NULL, prefix, NULL);
+
    +is changed to: +
    +  xpa = XPACmdNew(xclass, name);
+
    +

    +

  • Change the AddXPACommand() subroutine name to XPACmdAdd (with the same +calling sequence): +
    +  AddXPACommand(xpa, "file",
+    "\tdisplay a new file\n\t\t  requires: filename",
+    NULL, NULL, NULL, XPAReceiveFile, text, NULL);
+
    +is changed to: +
    +  XPACmdAdd(xpa, "file",
+    "\tdisplay a new file\n\t\t  requires: filename",
+    NULL, NULL, NULL, XPAReceiveFile, text, NULL);
+
    +

    +

  • The XPAXtAppInput() routine should be called just before XtAppMainLoop() +to add xpa fds to the Xt event loop: +
    +  /* add the xpas to the Xt loop */
+  XPAXtAddInput(app, NULL);
+
+  /* process events */
+  XtAppMainLoop(app);
+
    +

    +

  • Change NewXPA() to XPANew() and call XPAXtAddInput() if the XtAppMainLoop +routine already has been entered: +
    +  xpa = NewXPA(saotng->xim->toplevel, prefix, xparoot,
+               "FITS data or image filename\n\t\t  options: file type",
+               XPASendData, new, NULL,
+               XPAReceiveData, new, "SE");
+
    +is changed to: +
    +  sprintf(tbuf, "%s.%s", prefix, xparoot);
+  xpa = XPANew("SAOTNG", tbuf,
+               "FITS data or image filename\n\t\t  options: file type",
+               XPASendData, new, NULL,
+               XPAReceiveData, new, "SE");
+  XPAXtAddInput(XtWidgetToApplicationContext(saotng->xim->toplevel), xpa);
+
    +

    +

  • Change XPAInternalReceiveCommand() to XPACmdInternalReceive() +remove first argument in the calling sequence): +
    +  XPAInternalReceiveCommand(im->saotng->xim->toplevel,
+			    im->saotng, im->saotng->commands,
+			    "zoom reset", NULL, 0);
+
    +is changed to: +
    +  XPACmdInternalReceive(im->saotng, im->saotng->commands,
+			"zoom reset", NULL, 0);
+
    +

    +

  • Change DestroyXPA to XPAFree: +
    +  DestroyXPA(im->dataxpa);
+
    +is changed to: +
    +  XPAFree(im->dataxpa);
+
    +
+ + + + + +

XPAEnv: Environment Variables for XPA Messaging

+ + +

Summary

+Describes the environment variables which can be used to tailor the overall +XPA environment. + + +

Description

+

+The following environment variables are supported by XPA: +

+

+

XPA_ACL +
If XPA_ACL is true, then +host-based XPA Access Control +is turned on and only specified machines can access specified access +points. If false, then access control is turned off and any +machine can access point. The default is turn turn access control on. + +

+

XPA_ACLFILE +
If +XPA Access Control +is turned on, this variable specifies the name of the file containing +access control information for all access points started by this user. +The default file name is: $HOME/acls.xpa. + +

+

XPA_CONNECT_TIMEOUT +
When an XPA server first starts up, it immediately tries to +connect to the XPA name server program (xpans) on the host specified by +the XPA_NSINET variable. (If this connection fails on the +local host, and if xpans can be found in the path, then the name +server is started automatically.) Unfortunately, a mis-configured +network can cause this connect attempt to hang for many seconds while +the connect() system call times out. Therefore, an alarm is started +to interrupt the connect() call and prevent a long hang. The initial +value of the alarm timeout is 10 seconds, but can be changed by setting +this environment variable. If you want to disable the alarm and allow +the initial connect() to time out, set the value of this variable to +0. Normally, users would not change this variable at all. + +

+

XPA_CLIENT_DOXPA +
Normally, an XPA client (xpaget, xpaset, etc.) will process incoming +XPA server requests while awaiting the completion of the client request. +Setting this variable to "false" will prevent XPA server requests from +being processed by the client. + +

+

XPA_DEFACL +
If +XPA Access Control +is turned on, this variable specifies the default access control +condition for all access points, if the XPA_ACLFILE file does +not exist. The default acl is: $host:* $host +, meaning that +all processes on the host machine have full access to all access points. + +

+

XPA_HOST +
+For the INET socket method, XPA utilizes the canonical hostname (as +returned by the gethostname() routine) to construct the IP part of the +method id. Under some circumstances, this might not be a correct choice +of name and IP. For example, if an XPA server is started on a machine +running VPN, you might want to use the VPN name and IP instead of the +canonical host name, so that other machines in the VPN network can +access the server. In this case, you can set the XPA_HOST to be +the VPN name (if resolvable) or, more easily, the VPN IP. + +

+

XPA_IOCALLSXPA +
+Setting this variable causes all XPA socket IO calls to process +outstanding XPA requests whenever the primary socket is not ready for +IO. This means that a server making a client call will (recursively) +process incoming server requests while waiting for client completion. +This inter-IO XPA processing avoids a rare +XPA Race Condition: two or more +XPA servers sending messages to one another using an XPA client +routine such as XPASet() can deadlock while each waits for the other +server to respond. This can happen, for example, if the servers call +XPAPoll() with a time limit, and send messages in between the polling call. + +

+By default, this option is turned off, because we judge that the added +code complication and overhead involved will not be justified by the +amount of its use. Moreover, processing XPA requests within socket IO +can lead to non-intuitive results, since incoming server requests will +not necessarily be processed to completion in the order in which they +are received. + +

+

XPA_LOGNAME +
+XPA preferentially uses the de facto standard environment variable +LOGNAME to determine the username when registering an access point in +the name server. If this environment variable has been used for +something other than the actual user name (such as a log file name), +unexpected results can ensue. In such cases, use the XPA_LOGNAME +variable to set the user name. (If neither exists, then getpwuid(geteuid()) +is used as a last resort). + +

+

XPA_LONG_TIMEOUT +
XPA is designed to allow data to be sent from one process to +another over a long period of time (i.e., a program that generates +image data sends that data to an image display, but slowly) but it +also seeks to prevent hangs. This is done by supporting 2 timeout +periods: a short timeout for protocol communication +and a long for data communication. +

+The XPA_LONG_TIMEOUT variable controls the long +timeout and is used to prevent hangs in cases where communication +between the client and server that is not controlled by the +XPA interface itself. Transfer of data between client and server, or a +client's wait for a status message after completion of the server +callback, are two examples of this sort of communication. By default, +the long timeout is set to 180 seconds. +Setting the value to -1 will disable long timeouts and allow +an infinite amount of time. + +

+

XPA_MAXHOSTS +
The maximum number of access points that the programs +xpaset, xpaget, and xpainfo will +communicate with at one time. The default is 64, meaning, for +example, that the xpaset program will not send a message +to more than 100 access points at one time and xpaget will +not retrieve from more than 100 access points at one time. + +

+

XPA_METHOD +
+Determines the socket connection method used by this session of XPA. +The choices are: inet (to use INET or Internet-based +sockets), localhost (to use the machines localhost inet +socket), or local (unix) (to use UNIX sockets). The default +is INET. Using the inet method will allow access +from other machines (subject to access controls) but using +localhost or local will not. Localhost is most useful +for private access and when the machine in question is not connected +to the Internet. The unix method also can be used for private access +and non-Internet connections (Unix platforms only). +

+Once defined, the first registration of an XPA access point will +ensure that an instance of the +XPA Name Server (xpans) +is running that handles that connection method. All new access points +will use the new connection method but existing access points will use +the original method. + +

+

XPA_NSINET +
For the inet method of socket connection, this variable +specifies the host and port on which the +XPA Name Server (xpans) +is listens for new access points. The default is $host:$port, +meaning that the default XPA port (14285) on the current machine +(as returned by gethostname()) is used. If several machines were all +accessing the same XPA access points, you would use this variable to +specify that they all use the same name server to find out about these +access points. For example, a value of myhost:$port would +mean that the xpans name server is running on myhost and uses the +default port 12345. All machines would then get the XPA access points +registered with that name server, subject to access controls. +

+The port used by xpans to register its XPA access point normally is +taken to be one greater than the port on which it receives new access +points from XPA servers. You can specify a specific access point port +using the syntax machine:port1,port2, i.e., the access point port is +specified after the comma. For example, $host:12345,23456 will listen +for new access ports on 12345 and will accept XPA commands on 23456. + +

+

XPA_NSREGISTER +
+This boolean variable specifies whether a server registers its XPA +access point with the specified xpans name server. The default is +true. If set to false, the access point still is +set up but it is not registered with xpans and therefore cannot be +accessed by name. (It can be accessed by method, if the latter is +known.) Note that an access point can be registered later on (using +-remote or -proxy, for example). This variable mainly is useful in +cases where the Internet configuration is broken (so that registration +causes a DNS hang) but you still wish to and can use the server with a +remote xpans (e.g., ds9's Virtual Observatory capability). + +

+

XPA_NSUNIX +
For the local method of socket connection, this variable +specifies the name of the Unix file that will be used to access the +XPA Name Server (xpans). The default is +xpans_unix. This variable is not usually needed. Note that +is the local socket method is used, then remote machines will +not be able to access the xpans name server or the registered XPA access +points. + +

+

XPA_NSUSERS +
+This variable specifies whether other users' access points will be +returned by the +XPA Name Server (xpans) for use by +xpaget, xpaset, etc. +Generally speaking, it is sufficient to run one xpans name server per +machine and register the access points for all users with that xpans. +This means, for example, that if you request information from +ds9 by running: +
+  xpaget ds9 colormap
+
+you might get information from your own ds9 as well as +from another user running ds9 on the same machine. The +XPA_NSUSERS variable controls whether you want such access +to the access points of other users. +By default, only your own access points are returned, so +that, in the example above, you would only get the colormap information +from the ds9 you registered. If, however, you had set the value of the +XPA_NSUSERS variable to eric,fred, then you would be +able to communicate with both eric and fred's access points. Note that +this variable can be overridden using the -u switch on the +xpaget, xpaset, and xpainfo programs. + +

+

XPA_PORT +
+A semi-colon delimited list of user specified ports to use for specific +XPA access points. The format is each specification is: +
+class:template port1[ port2]
+
+where port1 is the main (command) port for the access point and +port2 is the (secondary) data port. If port2 is not specified, +it defaults to a value of 0 (meaning the system assigns the port). + +

+Specification of specific ports is useful, for example, when a machine +outside a firewall needs to communicate with a machine inside a +firewall. In such a case, the firewall should be configured to allow +socket connections to both the command and data port from the outside +machine, and the inside XPA program should be started up with the +outside machine in its ACL list. Then, when the inside program is +started with specified ports, outside XPA programs can use +"machine:port" to contact the inside access points, instead of the +access point names. That is, the machine outside the firewall does not +need access to the XPA name server: +

+export XPA_PORT="DS9:ds9 12345 12346"   # on machine "inside"
+cat foo.fits | xpaset inside:12345 fits # on machine "outside"
+
+Note that 2 ports are required for full XPA communication and +therefore 2 ports should be specified to go through a firewall. The +second port assignment is not important if you simply are assigning +the command port in order to communicate commands with a known +port (e.g., to bypass the xpans name server). If only one (command) +port is specified, the system will negotiate a random data port and +everything will work properly. + +

+This support is somewhat experimental. If you run into problems, please +let us know. + +

+

XPA_PORTFILE +
+A list of user-specified port to use for specific xpa access points. +The format of the file is: +
+class:template port1 [port2]
+
+where port1 is the main port for the access point and +port2 is the data port. If port2 is not specified, it defaults +to a value of 0 (meaning the system assigns the port). See +XPA_PORT above for an explanation of user-specified ports. + +

+

XPA_SHORT_TIMEOUT +
XPA is designed to allow data to be sent from one process to +another over a long period of time (i.e., a program that generates +image data sends that data to an image display, but slowly) but it +also seeks to prevent hangs. This is done by supporting 2 timeout +periods: a short timeout for protocol communication +and a long for data communication. +

+The XPA_SHORT_TIMEOUT variable +controls the short timeout and is used to prevent hangs +in cases where the XPA protocol requires internal communication between +the client and server that is controlled by the XPA interface +itself. Authentication is an example of this sort of communication, +as is the establishment of a data channel between the two processes. +The default value for the short is 30 seconds (which is +a pretty long time, actually). Setting the value to -1 will disable +short timeouts and allow an infinite amount of time. + +

+

XPA_SIGUSR1 +
If the value of this variable is true, then XPA will +catch SIGUSR1 signals when performing an I/O operation in order to +curtail that operation. This facility allows users to send a SIGUSR1 +signal to an XPA server if a client is hanging up the server by +sending or receiving data too slowly (timeouts also can be used -- see +above). When enabled in this way, the SIGUSR1 signal is ignored at all other +times, so that its safe to send the signal at any time. If the +variable is set to false, then SIGUSR1 is not used at +all. Turning off SIGUSR1 would be desired in cases there the program +uses SIGUSR1 for some other reason and does not want XPA interfering. +The default is to use the signal. + +

+

XPA_TIMESTAMP_ERRORS +
If XPA_TIMESTAMP_ERRORS is true, then error +messages will include a date/time string. This can be useful when +XPA errors are being saved in an error log (e.g. Web/CGI use). The +default is false. +
+ +

+

XPA_TMPDIR +
This variable specifies the directory into which XPA logs, Unix +socket files (when XPA_METHOD is local), etc. are +stored. The default is /tmp/.xpa. + +

+

XPA_VERBOSITY +
Specify the verbosity level of error messages. If the value is +set to 0, false, or off, then no error +messages are printed to stderr. If the value is 1, then +important XPA error messages will be output. If the value is +set to 2, XPA warnings about out-of-sync messages will also +be output. These latter almost always can be ignored. + +

+

XPA_VERSIONCHECK +
Specify whether a new access point should check its major and minor XPA +version number against the version used by the xpans name server at +registration time. The default is true. When checking is +performed, a warning is issued if the server major version is found to +be greater than the xpans version. Note that the check is performed +both by the XPA server and by the xpans process and warnings will be +issued by each. Also, instead of the values of true or +false, you can give this variable an integer value n. In this +case, each version checking process (i.e., the XPA-enabled server or +xpans) will print out a maximum of n warning messages (after which +version warnings are silently swallowed). +

+In general, it is a bad idea to run an XPA-enabled server program +using a version of XPA newer than the basic xpaset, xpaget, xpaaccess, +xpans programs. This sort of mismatch usually will not work due to +protocol changes. + + + + + +

XPACode: Where to Find Example/Test Code

+ + +

Summary

+

+The XPA source code directory contains two test programs, +stest.c, and ctest.c that can serve as +examples for writing XPA servers and clients, respectively. +They also can be used to test various features of XPA. + + +

Description

+

+To build the XPA test programs, execute: +

+   make All
+
+in the XPA source directory to generate the stest and +ctest programs. (NB: this should work on all platforms, +although we have had problems with unresolved externals on one +Sun/Solaris machine, for reasons still unknown.) +

+The stest program can be executed with no arguments to start +an XPA server that contains the access points: xpa, xpa1, +c_xpa (containing sub-commands cmd1 and cmd2), and i_xpa. +You then can use xpaset and xpaget to interact with these access points: +

+  cat xpa.c | xpaset xpa      # send to xpa
+  cat xpa.c | xpaset "xpa*"   # send to xpa and xpa1
+  xpaget xpa                  # receive from xpa
+  xpaget xpa*                 # receive from xpa and xpa1
+
+etc. You also can use ctest to do the same thing, or to iterate: +
+  ctest -s -l 100 xpa        # send to xpa 100 times
+  ctest -s -l 100 "xpa*"     # send to xpa and xpa1 100 times
+  ctest -g -l 100 xpa        # receive from xpa 100 times
+  ctest -g -l 100 "xpa*"     # receive from xpa and xpa1 100 times
+
+More options are available: see the stest.c and ctest.c code itself, which +were used extensively to debug XPA. + +

+The file test.tcl in the XPA source directory gives examples for using the +XPATclInterface. + + + + + +

XPA: Public Access to Data and Algorithms

+ + +

Summary

+This document is the Table of Contents for XPA. + + +

Description

+

+The XPA messaging system provides seamless communication between many +kinds of Unix programs, including X programs and Tcl/Tk programs. It +also provides an easy way for users to communicate with XPA-enabled +programs by executing XPA client commands in the shell or by utilizing +such commands in scripts. Because XPA works both at the programming +level and the shell level, it is a powerful tool for unifying any +analysis environment: users and programmers have great flexibility in +choosing the best level or levels at which to access XPA services, and +client access can be extended or modified easily at any time. + +

+A program becomes an XPA-enabled server by defining named points of +public access through which data and commands can be exchanged with +other client programs (and users). Using standard TCP sockets as a +transport mechanism, XPA supports both single-point and broadcast +messaging to and from these servers. It supports direct communication +between clients and servers, or indirect communication via an +intermediate message bus emulation program. Host-based access control +is implemented, as is as the ability to communicate with XPA servers +across a network. + +

+XPA implements a layered interface that is designed to be useful both +to software developers and to users. The interface consists of a +library of XPA client and server routines for use in C/C++ programs and +a suite of high-level user programs built on top of these libraries. +Using the XPA library, access points can be added to Tcl/Tk programs, +Xt programs, or to Unix programs that use the XPA event loop or any +event loop based on select(). Client access subroutines can be added +to any Tcl/Tk, Xt, or Unix program. Client access also is supported at +the command line via a suite of high-level programs. + +

XPAInet: XPA Communication Between Hosts

+ + +

Summary

+XPA uses standard inet sockets to support communication between two or +more host computers. + + +

Description

+

+When the Communication Method is set to +inet (as it is by default), XPA can be used to communicate +between different computers on the Internet. INET sockets utilize the +IP address of the given machine and a (usually random) port number to +communicate between processes on the same machine or between different +machines on the Internet. These standard Internet sockets are also +used by programs such as Netscape, ftp. etc. + +

+XPA supports a host-based Access Control mechanism +to prevent unauthorized access of XPA access points by other computers +on the Net. By default, only the machine on which the XPA server is +running can access XPA services. Therefore, setting up communication +between a local XPA server machine and a remote client machine +requires a two-part registration process: + +

    +
  • the XPA service on the local machine must be made known to the +remote machine +
  • the remote machine must be given permission to access the local +XPA service +
+ +Three methods by which this remote registration can be accomplished +are described below. + +

Manual Registration

+ +The first method is the most basic and does not require the remote +client to have xpans running. To use it, the local server simply +gives a remote client machine access to one or more XPA access points +using xpaset and the -acl sub-command. For example, +consider the XPA test program "stest" running on a local machine. By +default the access control for the access point named "xpa" is +restricted to that machine: +
+  [sh]$ xpaget xpa -acl
+  *:* 123.456.78.910 gisa
+  *:* localhost gisa
+
+Using xpaset and the -acl sub-command, a remote client +machine can be given permission to perform xpaget, xpaset, xpaaccess, +or xpainfo operations. For example, to allow the xpaget operation, the +following command can be issued on the local machine: +
+  [sh]$ xpaset -p xpa -acl "remote_machine g"
+
+This results in the following access permissions on the local machine: +
+  [sh]$ xpaget xpa -acl
+  XPA:xpa 234.567.89.012 g
+  *:* 123.456.78.910 gisa
+  *:* localhost gisa
+
+ +The remote client can now use the local server's xpans name server to +establish communication with the local XPA service. This can be done +on a call-by-call basis using the -i switch on xpaset, xpaget, etc: +
+  [sh]$ xpaget -i "local_machine:12345" xpa
+  class: XPA
+  name: xpa
+  method: 88877766:2778
+  sendian: little
+  cendian: big
+
+Alternatively, the XPA_NSINET variable on the remote machine can be +set to point directly to xpans on the local machine, removing +the need to override this value each time an XPA program is run: +
+  [csh]$ setenv XPA_NSINET 'karapet:$port'
+  [csh]$ xpaget xpa
+  class: XPA
+  name: xpa
+  method: 88877766:2778
+  sendian: little
+  cendian: big
+
+Here, '$port' means to use the default XPA name service port (14285). +not a port environment variable. + +

+Access permission for remote client machines can be stored in a file +on the local machine pointed to by the XPA_ACLFILE environment +variable or using the XPA_DEFACL environment variable. See XPA Access Control for more information. + +

Remote Registration

+ +If xpans is running on the remote client machine, then a local xpaset +command can be used with the -remote sub-command to +register the local XPA service in the remote name service, while at +the same time giving the remote machine permission to access the local +service. For example, assume again that "stest" is running on the +local machine and that xpans is also running on the remote machine. +To register access of this local xpa on the remote machine, use +the xpaset and the -remote sub-command: +
+  [sh]$ ./xpaset -p xpa -remote 'remote_machine:$port' +
+
+To register the local xpa access point on the remote machine with xpaget +access only, execute: +
+  [sh]$ ./xpaset -p xpa -remote 'remote_machine:$port' g
+
+Once the remote registration command is executed, the remote client +machine will have an entry such as the following in its own xpans name +service: +
+  [csh]$ xpaget xpans
+  XPA xpa gs 88877766:2839 eric
+
+The xpa access point can now be utilized on the remote machine without +further setup: +
+  [csh]$ xpaget xpa
+  class: XPA
+  name: xpa
+  method: 838e2f68:2839
+  sendian: little
+  cendian: big
+
+To unregister remote access from the local machine, use the same +command but with a '-' argument: +
+  [sh]$ xpaset -p xpa -remote 'remote_machine:$port' -
+
+The benefit of using remote registration is that communication with +remote access points can be mixed with that of other access points +on the remote machine. Using Access Point +Names and Templates, one XPA command can be used to send or +receive messages to the remote and local services. + +

XPANS Proxy Registration

+ +The two methods described above are useful when the local and remote +machines are able to communicate freely to one another. This would be +the case on most Local Area Networks (LANs) where all machines are +behind the same firewall and there is no port blocking between +machines on the same LAN. The situation is more complicated when the +XPA server is behind a firewall, where outgoing connections are +allowed, but incoming port blocking is implemented to prevent machines +outside the firewall from connecting to machines inside the +firewall. Such incoming port blocking will prevent xpaset and xpaget +from connecting to an XPA server inside a firewall. + +

+To allow locally fire-walled XPA services to register with remote +machines, we have implemented a proxy service within the xpans name +server. To register remote proxy service, xpaset and the +-remote sub-command is again used, but with an additional +-proxy argument added to the end of the command: +

+  [sh]$ ./xpaset -p xpa -remote 'remote_machine:$port' g -proxy
+
+Once a remote proxy registration command is executed, the remote +machine will have an entry such as the following in its own xpans name +service: +
+  [csh]$ xpaget xpans
+  XPA xpa gs @88877766:2839 eric
+
+The '@' sign in the name service entry indicates that xpans proxy +processing is being used for this access point. Other than that, from +the user's point of view, there is no difference in how this XPA +access point is contacted using XPA programs (xpaset, xpaget, etc.) or +libraries: +
+  [csh]$ xpaget xpa
+  class: XPA
+  name: xpa
+  method: 88877766:3053
+  sendian: little
+  cendian: big
+
+

+Of course, the underlying processing of the XPA requests is very much +different when xpans proxy is involved. Instead of an XPA program such +contacting the XPA service directly, it contacts the local xpans. +Acting as a proxy server, xpans communicates with the XPA service +using the command channel established at registration time. Commands +(including establishing a new data channel) are sent between xpans and +the XPA service to set up a new message transfer, and then data is fed +to/from the xpa request, through xpans, from/to the XPA service. In +this way, it can be arranged so that connections between the +fire-walled XPA service and the remote client are always initiated by +the XPA service itself. Thus, incoming connections that would be +blocked by the firewall are avoided. Note that there is a performance +penalty for using the xpans/proxy service. Aside from extra overhead +to set up proxy communication, all data must be sent through the +intermediate proxy process. + +

+The xpans proxy scheme requires that the remote client allow the local +XPA server machine to connect to the remote xpans/proxy server. If the +remote client machine also is behind a port-blocking firewall, such +connections will be disallowed. In this case, the only solution is to +open up some ports on the remote client machine to allow incoming +connections to xpans/proxy. Two ports must be opened (for command and +data channel connections). By default, these two ports are 14285 and +14287. The port numbers can be changed using the XPA_NSINET +environment variable. This variable takes the form: +

+  setenv XPA_NSINET machine:port1[,port2[,port3]]
+
+where port1 is the main connecting port, port2 is the XPA access port, +and port3 is the secondary data connecting port. The second and third +ports are optional and default to port1+1 and port1+2, respectively. +It is port1 and port3 that must be left open for incoming connections. + +

+For example, to change the port assignments so that xpans listens +for registration commands on port 12345 and data commands on port 28573: +

+  setenv XPA_NSINET myhost:12345
+
+Alternatively, all three ports can be assigned explicitly: +
+  setenv XPA_NSINET remote:12345,3000,12346
+
+In this case 12345 and 12346 should be open for incoming connections. +The XPA access port (which need not be open to the outside +world) is set to 3000. + +

+Finally, note that we currently have no mechanism to cope with +Internet proxy servers (such as SOCKS servers). If an XPA service is +running on a machine that cannot connect directly to outside machines, +but goes through a proxy server instead, there currently is no way to +register that XPA service with a remote machine. We hope to implement +support for SOCKS proxy in a future release. + + + + + +

XPACommon: Getting Common Information About Access Points

+ + +

Summary

+

+There are various kinds of generic information you can retrieve about +an XPA access point by using the xpaget command. + + +

Description

+

+You can find out which XPA access points have been registered with +the currently running +XPA name server +by executing the +xpaget +command to retrieve info from the XPA name server: +

+  xpaget xpans
+
+If, for example, the +stest test server program +is running, the following XPA access points will be returned (the specifics +of the returned info will vary for different machines and users): +
+  XPA xpa gs 838e2f67:1262 eric
+  XPA xpa1 gs 838e2f67:1266 eric
+  XPA c_xpa gs 838e2f67:1267 eric
+  XPA i_xpa i 838e2f67:1268 eric
+
+Note that access to this information is subject to the usual +XPA Access Control restrictions. + +

+Each XPA access point supports a number of reserved sub-commands that provide +access to different kinds of information, e.g. the access control for +that access point. These sub-commands can be executed by using +xpaset +or +xpaget +at the command line, or +XPAGet() +or +XPASet() +in programs, e.g: +

+  xpaget ds9 -acl
+  xpaget ds9 -help
+  xpaget ds9 env FOO
+
+  xpaset -p ds9 env FOO foofoo
+
+With the exception of -help and -version, reserved +sub-commands are available only on the machine on which the XPA server +itself is running. + +The following reserved sub-commands are defined for all access points: +
+ +

+

-acl get (set) the access control list [options: host type acl, for set] +
+The 'xpaset' option allows you to add a new acl for a given host, or change +the acl for an existing host. See +XPA Access Control +for more information. +This access point is available only on the server machine. + +

+

-env get (set) an environment variable [options: name (value, for set)] +
+The 'xpaget' option will return the value of the named environment +variable. The 'xpaset' option will set the value of the names +variable to the specified value. +This access point is available only on the server machine. +(Please be advised that we have had problems setting environment +variables in static Tcl/Tk programs such as ds9 running under Linux.) + +

+

-clipboard set(get) information on a named clipboard +
Clients can store ASCII state information on any number of named +clipboards. Clipboards of the same name created by clients on +different machines are kept separate. The syntax for creating a +clipboard is: +
+  [data] | xpaset [server] -clipboard add|append [clipboard_name]
+  xpaset -p [server] -clipboard delete [clipboard_name]
+
+Use "add" to create a new clipboard or replace the contents of an existing +one. Use "append" to append to an existing clipboard. +

+Information on a named clipboard is retrieved using: +

+  xpaget [server] -clipboard [clipboard_name]
+
+

+

-exec set: execute commands from buffer [options: none] +
+If -exec is specified in the paramlist of an 'xpaset' call, then further +sub-commands will be retrieved from the data buffer. + +

+

-help get: return help string for this XPA or sub-command [options: name (for sub-commands)] +
+Each XPA access point and each XPA sub-command can have a help string +associated with it that is specified when the access point is defined. +The -help option will return this help string. For XPA access points +that contain user-defined sub-commands, you can get the help string +for a particular sub-command by specifying its name, or else get the +help strings for all sub-commands if not name is specified. + +

+

-ltimeout get (set) the long timeout value [options: seconds|reset] +
+The 'xpaget' option will return the value of the long timeout (in seconds). +The 'xpaset' option will set the value of the long timeout. If "reset" is +specified, then the timeout value will be reset to the default value. + +

+

-nsconnect set: re-establish name server connection to all XPA's [options: none] +
+If the +XPA Name Server (xpans) +process has terminated unexpectedly and then re-started, this +sub-command can be used to re-establish the connection. You use it by +sending the command to the [name:port] or [file] of the access point +instead of to the XPA name (since the latter requires the xpans +connection!): +
+  xpaset -p 838e2f67:1268 -nsconnect
+
+See xpans for more information. + +

+

-nsdisconnect set: break name server connection to all XPA's [options: none] +
+This sub-command will terminate the connection to the +XPA Name Server (xpans), thereby making +all access points inaccessible except through their underlying [name:port] +or [file] identifiers. I forget why we added it, it seems pretty useless. + +

+

-stimeout get (set) the short timeout value [options: seconds|reset] +
+The 'xpaget' option will return the value of the short timeout (in seconds). +The 'xpaset' option will set the value of the short timeout. If "reset" is +specified, then the timeout value will be reset to the default value. + +

+

-remote set: register xpa with remote server [options: host[:port] [acl]] [-proxy] +
+This sub-command will register the XPA access point with the XPA name +server (xpans) on the specified host (which must already be running). +The specified host also is given access control to the access point, +using the specified acl or the default acl of "+" (meaning the remote +host can xpaset, xpaget, xpainfo or xpaaccess). If the acl is +specified as "-", then the access point is unregistered. +See Communication Between Machines +for more information on how this sub-command is used. + +

+

-version get: return XPA version string [options: none] +
+The version refers to the version of XPA used to define this access point +(currently something like 2.0). + +
+ +

+You can add your own reserved commands to all XPA access points by using the +XPACmdAdd() +routine, passing the XPA handle returned by XPA XPAGetReserved(void) +as the first argument. Note again that these will only be available on the +machine where the XPA service is running. + + + + + +

XPAIntro: Introduction to the XPA Messaging System

+ + +

Summary

+

+A brief introduction to the XPA messaging system, which provides +seamless communication between all kinds of Unix event-driven +programs, including X programs, Tcl/Tk programs, and Perl programs. + + +

Description

+

+The XPA messaging system provides seamless communication between all +kinds of Unix programs, including X programs, Tcl/Tk programs, and +Perl programs. It also provides an easy way for users to communicate +with these XPA-enabled programs by executing XPA client commands in +the shell or by utilizing such commands in scripts. Because XPA works +both at the programming level and the shell level, it is a powerful +tool for unifying any analysis environment: users and programmers have +great flexibility in choosing the best level or levels at which to +access XPA services, and client access can be extended or modified +easily at any time. + +

+A program becomes an XPA-enabled server by defining named points of +public access through which data and commands can be exchanged with +other client programs (and users). Using standard TCP sockets as +a transport mechanism, XPA supports both single-point and broadcast +messaging to and from these servers. It supports direct communication +between clients and servers, or indirect communication via an +intermediate message bus emulation program. Host-based access control +is implemented, as is as the ability to communicate with XPA servers +across a network. + +

+XPA implements a layered interface that is designed to be useful both +to software developers and to users. The interface consists of a +library of XPA client and server routines for use in programs and a +suite of high-level user programs built on top of these libraries. +Using the XPA library, access points can be added to +Tcl/Tk +programs, +Xt +programs, or to Unix programs that use the XPA event loop or any +event loop based on select(). Client access subroutines can be added +to any Tcl/Tk or Unix program. Client access also is supported at the +command line via a suite of high-level programs. + +

+The major components of the XPA layered interface are: +

    +
  • +A set of XPA server routines, centered on +XPANew(), +which are used by XPA server programs to tag public access points with +string identifiers and to register send and receive callbacks for +these access points. + +
  • +A set of XPA client routines, centered on the +XPASet() +and +XPAGet(), +which are used by external client applications to exchange data and +commands with an XPA server. + +
  • +High-level programs, centered on +xpaset +and +xpaget, +which allow data +and information to be exchanged with XPA server programs from the +command line and from scripts. These programs have the command syntax: +
    +  [data] | xpaset  [qualifiers ...]
+           xpaget  [qualifiers ...]
+
    +
  • +An XPA name server program, +xpans, +through which XPA access point names are +registered by servers and distributed to clients. +
+ +

+Defining an XPA access point is easy: a server application calls +XPANew(), +XPACmdNew(), +or the experimental +XPAInfoNew() +routine to +create a named public access point. An XPA service can specify "send" +and "receive" callback procedures (or an "info" procedure in the case +of XPAInfoNew()) to be executed by the program when an external +process either sends data or commands to this access point or requests +data or information from this access point. Either of the callbacks +can be omitted, so that a particular access point can be specified as +read-only, read-write, or write-only. Application-specific client +data can be associated with these callbacks. Having defined one or +more public access points in this way, an XPA server program enters +its usual event loop (or uses the standard XPA event loop). + +

+Clients communicate with these XPA public access points +using programs such as +xpaget, +xpaset, and +xpainfo +(at the command line), +or routines such as +XPAGet(), +XPASet(), +and +XPAInfo() +within a program. Both methods require specification of the name of +the access point. The xpaget program returns data or other +information from an XPA server to its standard output, while the +xpaset program sends data or commands from its standard input to an +XPA application. The corresponding API routines set/get data to/from +memory, returning error messages and other info as needed. If a +template +is used to specify the access point name (e.g., "ds9*"), then +communication will take place with all servers matching that template. + +

+Please note that XPA currently is not thread-safe. All XPA calls must be +in the same thread. + + + + + +

XPAMethod: XPA Communication Methods

+ + +

Summary

+

+XPA supports both inet and unix (local) socket communication. + + +

Description

+

+XPA uses sockets for communication between processes. It supports +three methods of socket communication: inet, localhost, and unix. In +general, the same method should be employed for all XPA processes in a +session and the global environment variable XPA_METHOD should be used +to set up the desired method. By default, the preferred method is +"inet", which is appropriate for most users. You can set up a +different method by typing something like: +

+  setenv XPA_METHOD local              # unix csh
+  XPA_METHOD=local; export XPA_METHOD  # unix sh, bash, windows/cygwin
+  set XPA_METHOD=localhost             # dos/windows
+
+The options for XPA_METHOD are: inet, unix (or +local), and localhost. On Unix machines, this +environment setup command can be placed in your shell init file +(.cshrc, .profile, .bashrc, etc.) On Windows platforms, it can be +placed in your AUTOEXEC.BAT file (I think!). + +

+By default, inet sockets are used by XPA. These are the standard +Internet sockets that are used by programs such as Netscape, +ftp. etc. Inet sockets utilize the IP address of the given machine and +a (usually random) port number to communicate between processes on the +same machine or between different machines on the Internet. (Note that +XPA has an Access Control mechanism to +prevent unauthorized access of XPA access points by other computers on +the Net). For users connected to the Internet, this usually is the +appropriate communication method. For more information about setting +up XPA communication between machines, see +Communication Between Machines. + +

+In you are using XPA on a machine without an Internet connection, then +inet sockets are not appropriate. In fact, an XPA process often will +hang for many seconds while waiting for a response from the Domain +Name Service (DNS) when using inet sockets. Instead of inet sockets, +users on Unix platforms can also use unix sockets (also known +as local sockets). These sockets are based on the local file system +and do not make use of the DNS. They generally are considered to be +faster than inet sockets, but they are not implemented under +Windows. Use local sockets as a first resort if you are on a Unix +machine that is not connected to the Internet. + +

+Users not connected to the Internet also can use localhost +sockets. These are also inet-type sockets but the IP address used for +the local machine is the localhost address, 0x7F000001, instead +of the real IP of the machine. Depending on how sockets are set up for +a given platform, communication with the DNS usually is not required in +this case (though of course, XPA cannot interact with other machines). +The localhost method will generally work on both Unix and Windows +platforms, but whether the DNS is required or not is subject to +individual configurations. + +

+A final warning/reminder: if your XPA-enabled server hangs at startup +time and your XPA_METHOD is inet, the problem probably is +related to an incorrect Internet configuration. This can be confirmed +by using the unix method or (usually) the localhost +method. You can use these alternate methods if other hosts do not need +access to the XPA server. + + + + + +

Summary

+What does XPA stand for? Who knows anymore! + + +

Description

+

+What does XPA stand for? Dunno! The XPA messaging system originally +was built on top of the X Window System and XPA was the mnemonic for +X Public Access, to emphasize that we were providing public +access to previously private data and algorithms in Xt programs. Now +that XPA no longer is tied to X, it can be argued that we ought to +change the name (how about SPAM: simple public access mechanism +), but XPA is in wide-spread use in the astronomical community of +its birth, and the name has taken on a life of its own. If anyone can +think of what XPA now means, please let us know. + +

+If you think this is bad, consider the MMT Telescope on Mount Hopkins, +Arizona. When first installed twenty years ago, it featured an array +of six 72-inch diameter mirrors. from which came its name: the +Multiple Mirror Telescope. In spring of 1999, these mirrors +were replaced by a single 21 and 1/2 -foot diameter primary mirror, +the largest single-piece glass reflector on the North American +continent. And now MMT stands for ... MMT! + + + + + +

+ + +

Summary

+

+When XPA can't allocate memory, it exits. You can arrange to have it call +longjmp() instead. + + +

Description

+

+When an XPA server or client cannot allocate memory, it will attempt to +output an error message and then exit. If this is not satisfactory (e.g., +perhaps your program is interactive and can recover from OOM errors), you +can tell XPA to call longjmp() to go to a recovery branch. To pass the +requisite jmp_buf variable to XPA, make the following call: +

+  XPASaveJmp(void *env);
+
+The value of env is the address of a jmp_buf variable that was previously +passed to setjmp(). For example: +
+  jmp_buf env;
+  ...
+  if( setjmp(jmp_buf) != 0 ){
+    /* out of memory -- take corrective action, if possible */
