# Commands tested in this file: socket. # # This file contains a collection of tests for one or more of the Tcl built-in # commands. Sourcing this file into Tcl runs the tests and generates output # for errors. No output means no errors were found. # # Copyright (c) 1994-1996 Sun Microsystems, Inc. # Copyright (c) 1998-2000 Ajuba Solutions. # # See the file "license.terms" for information on usage and redistribution of # this file, and for a DISCLAIMER OF ALL WARRANTIES. # Running socket tests with a remote server: # ------------------------------------------ # # Some tests in socket.test depend on the existence of a remote server to # which they connect. The remote server must be an instance of tcltest and it # must run the script found in the file "remote.tcl" in this directory. You # can start the remote server on any machine reachable from the machine on # which you want to run the socket tests, by issuing: # # tcltest remote.tcl -port 2048 # Or choose another port number. # # If the machine you are running the remote server on has several IP # interfaces, you can choose which interface the server listens on for # connections by specifying the -address command line flag, so: # # tcltest remote.tcl -address your.machine.com # # These options can also be set by environment variables. On Unix, you can # type these commands to the shell from which the remote server is started: # # shell% setenv serverPort 2048 # shell% setenv serverAddress your.machine.com # # and subsequently you can start the remote server with: # # tcltest remote.tcl # # to have it listen on port 2048 on the interface your.machine.com. # # When the server starts, it prints out a detailed message containing its # configuration information, and it will block until killed with a Ctrl-C. # Once the remote server exists, you can run the tests in socket.test with the # server by setting two Tcl variables: # # % set remoteServerIP # % set remoteServerPort 2048 # # These variables are also settable from the environment. On Unix, you can: # # shell% setenv remoteServerIP machine.where.server.runs # shell% senetv remoteServerPort 2048 # # The preamble of the socket.test file checks to see if the variables are set # either in Tcl or in the environment; if they are, it attempts to connect to # the server. If the connection is successful, the tests using the remote # server will be performed; otherwise, it will attempt to start the remote # server (via exec) on platforms that support this, on the local host, # listening at port 2048. If all fails, a message is printed and the tests # using the remote server are not performed. package require tcltest 2 namespace import -force ::tcltest::* # Some tests require the Thread package or exec command testConstraint thread [expr {0 == [catch {package require Thread 2.7-}]}] testConstraint exec [llength [info commands exec]] # Produce a random port number in the Dynamic/Private range # from 49152 through 65535. proc randport {} { expr {int(rand()*16383+49152)} } # Test the latency of tcp connections over the loopback interface.
