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/xpa/LICENSE b/xpa/LICENSE deleted file mode 100644 index a9c1e78..0000000 --- a/xpa/LICENSE +++ /dev/null @@ -1,21 +0,0 @@ -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.

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().

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. - -

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. -

-
-  int XPAGet(XPA xpa,

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. - - - - - -

XPAName: What does XPA stand for?

- - -

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! - - - - - -

Xpaoom: What happens when XPA runs out of memory?

- - -

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.

-  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 */

Client access also is supported at -the command line via a suite of high-level programs. - - -Choose from the following topics: - - - -=over 4 - - - - -=item * - -Introduction to XPA -[xpaintro(n)] - - -=item * - -Access Point Names and Templates -[xpatemplate(n)] - - -=item * - -Getting Common Information About Access Points -[xpacommon(n)] - - -=item * - -Communication Methods -[xpamethod(n)] - - -=item * - -Communication Between Hosts -[xpainet(n)] - - -=item * - -Distinguishing Users -[xpausers(n)] - - - -=item * - -XPA User Programs - - -=over 4 - - - - -=item * - -xpaget: get data and info -[xpaget(1)] - - -=item * - -xpaset: send data and info -[xpaset(1)] - - -=item * - -xpainfo: send info alert -[xpainfo(1)] - - -=item * - -xpaaccess: get access point info -[xpaaccess(1)] - - -=item * - -xpamb: message bus emulation -[xpamb(1)] - - -=item * - -xpans: the XPA name server -[xpans(1)] - - -=back - - - - - -=item * - -XPA Server Routines - - -=over 4 - - - - -=item * - -XPANew: define a new access point -[xpanew(3)] - - -=item * - -XPACmdNew: define a new command access point -[xpacmdnew(3)] - - -=item * - -XPACmdAdd: add a command -[xpacmdadd(3)] - - -=item * - -XPACmdDel: delete a command -[xpacmddel(3)] - - -=item * - -XPAInfoNew: define an info access point -[xpainfonew(3)] - - -=item * - -XPAFree: free an access point -[xpafree(3)] - - -=item * - -XPAMainLoop: event loop for select server -[xpamainloop(3)] - - -=item * - -XPAPoll: poll for XPA events -[xpapoll(3)] - - -=item * - -XPACleanup: release reserved XPA memory -[xpacleanup(3)] - - -=item * - -XPA Server Macros: accessing structure internals -[xpamacros(3)] - - -=item * - -XPA Race Conditions: how to avoid them -[xparace(3)] - - -=item * - -XPA Out of Memory (OOM) errors -[xpaoom(3)] - - -=back - - - - - -=item * - -XPA Client Routines - - -=over 4 - - - - -=item * - -XPAOpen: open a persistent client connection -[xpaopen(3)] - - -=item * - -XPAClose: close persistent client connection -[xpaclose(3)] - - -=item * - -XPAGet: get data -[xpaget(3)] - - -=item * - -XPASet: send data or commands -[xpaset(3)] - - -=item * - -XPAInfo: send an info alert -[xpainfo(3)] - - -=item * - -XPAGetFd: get data and write to an fd -[xpagetfd(3)] - - -=item * - -XPASetFd: read data from and fd and send -[xpasetfd(3)] - - -=item * - -XPANSLookup: look up an access point -[xpanslookup(3)] - - -=item * - -XPAAccess: get access info -[xpaaccess(3)] - - -=item * - -The XPA/Xt Interface: Xt interface to XPA -[xpaxt(n)] - - -=item * - -The XPA/Tcl Interface: Tcl interface to XPA -[xpatcl(n)] - - -=back - - - - - -=item * - -Tailoring the XPA Environment - - -=over 4 - - - - -=item * - -Environment Variables -[xpaenv(n)] - - -=item * - -Access Control -[xpaacl(n)] - - -=back - - - - - -=item * - -Miscellaneous - - -=over 4 - - - - - -=item * - -Where to Find Example/Test Code - - -=item * - -User Changes Between XPA 1.0 and 2.0 - - -=item * - -API Changes Between XPA 1.0 and 2.0 - - -=item * - -What Does XPA Stand For, Anyway? - - -=back - - - - - -=back - - - - - - -=cut diff --git a/xpa/doc/pod/xpaaccess.pod b/xpa/doc/pod/xpaaccess.pod deleted file mode 100644 index ab34b9b..0000000 --- a/xpa/doc/pod/xpaaccess.pod +++ /dev/null @@ -1,102 +0,0 @@ -=pod - -=head1 NAME - - - -B - - - -=head1 SYNOPSIS - - - - - -xpaaccess [-c] [-h] [-i nsinet] [-m method] [-n] [-t sval,lval] [-u users] -v
