2006-04-01 Paul D. Smith * scripts/functions/realpath: Don't run tests with multiple initial slashes on Windows: those paths mean something different. 2006-03-19 Paul D. Smith * scripts/features/parallelism: Test that the jobserver is properly managed when we have to re-exec the master instance of make. 2006-03-17 Boris Kolpackov * scripts/features/statipattrules: Add tests for bug #16053. 2006-03-09 Paul Smith * scripts/features/escape: Use "pre:" not "p:" to avoid conflicts with DOS drive letters. Fixes Savannah bug #15947. * test_driver.pl (run_each_test): Set the status properly even when a test fails to execute. Fixes Savannah bug #15942. * scripts/functions/foreach: Use a different environment variable other than PATH to avoid differences with Windows platforms. Fixes Savannah bug #15938. 2006-03-05 Paul D. Smith * run_make_tests.pl (set_more_defaults): Add CYGWIN_NT as a port type W32. Fixed Savannah bug #15937. * scripts/features/default_names: Don't call error() when the test fails. Fixes Savannah bug #15941. 2006-02-17 Paul D. Smith * scripts/features/targetvars: Test a complex construction which guarantees that we have to merge variable lists of different sizes. Tests for Savannah bug #15757. 2006-02-15 Paul D. Smith * scripts/functions/error: Make sure filename/lineno information is related to where the error is expanded, not where it's set. * scripts/functions/warning: Ditto. * scripts/functions/foreach: Check for different error conditions. * scripts/functions/word: Ditto. * scripts/variables/negative: Test some variable reference failure conditions. * scripts/options/warn-undefined-variables: Test the --warn-undefined-variables flag. 2006-02-09 Paul D. Smith * run_make_tests.pl (set_more_defaults): Update valgrind support for newer versions. * test_driver.pl (toplevel): Skip all hidden files/directories (ones beginning with "."). * scripts/functions/andor: Tests for $(and ..) and $(or ...) functions. 2006-02-08 Boris Kolpackov * scripts/features/parallelism: Add a test for bug #15641. 2006-02-06 Paul D. Smith * scripts/options/dash-W: Add a test for bug #15341. 2006-01-03 Paul D. Smith * scripts/variables/automatic: Add a test for bug #8154. * README: Update to reflect the current state of the test suite. 2005-12-12 Paul D. Smith * scripts/features/parallelism, scripts/functions/wildcard, scripts/targets/FORCE, scripts/targets/PHONY, scripts/targets/SILENT: Use the default setting for $delete_command. Fixes bug #15085. * run_make_tests.pl (get_this_pwd) [VMS]: Use -no_ask with delete_file. 2005-12-11 Paul D. Smith * scripts/misc/general4: Test implicit rules with '$' in the prereq list & prereq patterns. * scripts/features/se_implicit: Add in .SECONDEXPANSION settings. 2005-12-09 Boris Kolpackov * scripts/features/patternrules: Add a test for bug #13022. 2005-12-07 Boris Kolpackov * scripts/features/double_colon: Add a test for bug #14334. 2005-11-17 Boris Kolpackov * scripts/functions/flavor: Add a test for the flavor function. 2005-11-14 Boris Kolpackov * scripts/variables/INCLUDE_DIRS: Add a test for the .INCLUDE_DIRS special variable. 2005-10-24 Paul D. Smith * scripts/misc/general4: Test '$$' in prerequisites list. * scripts/features/statipattrules: Rewrite to use run_make_test(). Add various static pattern info. * scripts/features/se_statpat: Enable .SECONDEXPANSION target. * scripts/features/se_explicit: Add tests for handling '$$' in prerequisite lists with and without setting .SECONDEXPANSION. * scripts/features/order_only: Convert to run_make_test(). * run_make_tests.pl (set_more_defaults): If we can't get the value of $(MAKE) from make, then fatal immediately. 2005-08-31 Paul D. Smith * run_make_tests.pl (get_this_pwd): Require the POSIX module (in an eval to trap errors) and if it exists, use POSIX::getcwd to find the working directory. If it doesn't exist, go back to the previous methods. This tries to be more accurate on Windows systems. 2005-08-29 Paul D. Smith * scripts/functions/abspath: Add some text to the error messages to get a better idea of what's wrong. Make warnings instead of errors. * scripts/features/patspecific_vars: Don't use "test", which is UNIX specific. Print the values and let the test script match them. 2005-08-25 Paul Smith * scripts/variables/SHELL: Use a /./ prefix instead of //: the former works better with non-UNIX environments. Fixes Savannah bug #14129. 2005-08-13 Boris Kolpackov * scripts/functions/wildcard: Wrap calls to $(wildcard ) with $(sort) so that the resulting order is no longer filesystem- dependant. 2005-08-10 Boris Kolpackov * scripts/features/statipattrules: Add a test for Savannah bug #13881. 2005-08-07 Paul D. Smith * scripts/features/parallelism: Add a test for a bug reported by Michael Matz (matz@suse.de) in which make exits without waiting for all its children in some situations during parallel builds. 2005-07-08 Paul D. Smith * test_driver.pl: Reset the environment to a clean value every time before we invoke make. I'm suspicious that the environment isn't handled the same way in Windows as it is in UNIX, and some variables are leaking out beyond the tests they are intended for. Create an %extraENV hash tests can set to add more env. vars. * tests/scripts/features/export: Change to use %extraENV. * tests/scripts/functions/eval: Ditto. * tests/scripts/functions/origin: Ditto. * tests/scripts/options/dash-e: Ditto. * tests/scripts/variables/SHELL: Ditto. 2005-06-27 Paul D. Smith * scripts/options/dash-W: Use 'echo >>' instead of touch to update files. * scripts/features/reinvoke: Rewrite to be safer on systems with subsecond timestamps. * scripts/features/patternrules: False exits with different error codes on different systems (for example, Linux => 1, Solaris => 255). * scripts/options/dash-W: Set the timestamp to foo.x in the future, to be sure it will be considered updated when it's remade. 2005-06-26 Paul D. Smith * scripts/functions/shell: New test suite for the shell function. 2005-06-25 Paul D. Smith * scripts/features/include: Test include/-include/sinclude with no arguments. Tests fix for Savannah bug #1761. * scripts/misc/general3: Implement comprehensive testing of backslash-newline behavior in command scripts: various types of quoting, fast path / slow path, etc. Tests fix for Savannah bug #1332. * scripts/options/symlinks: Test symlinks to non-existent files. Tests fix for Savannah bug #13280. * scripts/misc/general3: Test semicolons in variable references. Tests fix for Savannah bug #1454. * scripts/variables/MAKE_RESTARTS: New file: test the MAKE_RESTARTS variable. * scripts/options/dash-B: Test re-exec doesn't loop infinitely. Tests fix for Savannah bug #7566. * scripts/options/dash-W: New file: test the -W flag, including re-exec infinite looping. 2005-06-12 Paul D. Smith * scripts/misc/close_stdout: Add a test for Savannah bug #1328. This test only works on systems that have /dev/full (e.g., Linux). 2005-06-09 Paul D. Smith * scripts/functions/foreach: Add a test for Savannah bug #11913. 2005-05-31 Boris Kolpackov * scripts/features/include: Add a test for Savannah bug #13216. * scripts/features/patternrules: Add a test for Savannah bug #13218. 2005-05-13 Paul D. Smith * scripts/features/conditionals: Add tests for the new if... else if... endif syntax. 2005-05-03 Paul D. Smith * scripts/variables/DEFAULT_GOAL: Rename DEFAULT_TARGET to DEFAULT_GOAL. 2005-05-02 Paul D. Smith * scripts/features/parallelism: Add a test for exporting recursive variables containing $(shell ) calls. Rewrite this script to use run_make_test() everywhere. 2005-04-07 Paul D. Smith * scripts/targets/SECONDARY: Add a test for Savannah bug #12331. 2005-03-15 Boris Kolpackov * scripts/variables/automatic: Add a test for Savannah bug #12320. 2005-03-10 Boris Kolpackov * scripts/features/patternrules: Add a test for Savannah bug #12267. 2005-03-09 Boris Kolpackov * scripts/variables/DEFAULT_TARGET: Add a test for Savannah bug #12266. 2005-03-04 Boris Kolpackov * scripts/features/patternrules: Add a test for Savannah bug #12202. 2005-03-03 Boris Kolpackov * scripts/features/se_implicit: Add a test for stem termination bug. Add a test for stem triple-expansion bug. * scripts/features/se_statpat: Add a test for stem triple-expansion bug. * scripts/features/statipattrules: Change test #4 to reflect new way empty prerequisite list is handled. 2005-03-01 Boris Kolpackov * scripts/features/statipattrules: Add a test for Savannah bug #12180. 2005-02-28 Paul D. Smith * scripts/options/dash-q: Add a test for Savannah bug # 7144. * scripts/options/symlinks: New file to test checking of symlink timestamps. Can't use filename dash-L because it conflicts with dash-l on case-insensitive filesystems. * scripts/variables/MAKEFILE_LIST, scripts/variables/MFILE_LIST: Rename MAKEFILE_LIST test to MFILE_LIST, for systems that need 8.3 unique filenames. 2005-02-28 Boris Kolpackov * scripts/variables/DEFAULT_TARGET: Test the .DEFAULT_TARGET special variable. 2005-02-27 Boris Kolpackov * scripts/features/se_explicit: Test the second expansion in explicit rules. * scripts/features/se_implicit: Test the second expansion in implicit rules. * scripts/features/se_statpat: Test the second expansion in static pattern rules. * scripts/variables/automatic: Fix to work with the second expansion. * scripts/misc/general4: Add a test for bug #12091. 2005-02-27 Paul D. Smith * scripts/functions/eval: Check that eval of targets within command scripts fails. See Savannah bug # 12124. 2005-02-26 Paul D. Smith * test_driver.pl (compare_output): If a basic comparison of the log and answer doesn't match, try harder: change all backslashes to slashes and all CRLF to LF. This helps on DOS/Windows systems. 2005-02-09 Paul D. Smith * scripts/features/recursion: Test command line variable settings: only one instance of a given variable should be provided. 2004-11-30 Boris Kolpackov * tests/scripts/functions/abspath: New file: test `abspath' built-in function. * tests/scripts/functions/realpath: New file: test `realpath' built-in function. 2004-11-28 Paul D. Smith * scripts/options/dash-C [WINDOWS32]: Add a test for bug #10252; this doesn't really test anything useful in UNIX but... * scripts/variables/SHELL: New file: test proper handling of SHELL according to POSIX rules. Fixes bug #1276. 2004-10-21 Boris Kolpackov * scripts/functions/word: Test $(firstword ) and $(lastword ). 2004-10-05 Boris Kolpackov * scripts/features/patspecific_vars: Test simple/recursive variable expansion. 2004-09-28 Boris Kolpackov * scripts/features/include: Test dontcare flag inheritance when rebuilding makefiles. 2004-09-27 Boris Kolpackov * scripts/features/patspecific_vars: Test exported variables. 2004-09-22 Paul D. Smith * run_make_tests.pl (run_make_test): Don't add newlines to the makestring or answer if they are completely empty. * scripts/features/patternrules: Rename from implicit_prereq_eval. * scripts/test_template: Rework the template. 2004-09-21 Boris Kolpackov * run_make_tests.pl: Change `#!/usr/local/bin/perl' to be `#!/usr/bin/env perl'. * scripts/features/implicit_prereq_eval: Test implicit rule prerequisite evaluation code. 2004-09-21 Paul D. Smith * run_make_tests.pl (run_make_test): Enhance to allow the make string to be undef: in that case it reuses the previous make string. Allows multiple tests on the same makefile. * scripts/variables/flavors: Add some tests for prefix characters interacting with define/endef variables. 2004-09-20 Paul D. Smith * scripts/functions/substitution: Rewrite to use run_make_test() interface, and add test for substitution failures reported by Markus Mauhart . 2004-03-22 Paul D. Smith * test_driver.pl (run_each_test, toplevel, compare_output): Change to track both the testing categories _AND_ the number of individual tests, and report both sets of numbers. 2004-02-21 Paul D. Smith * scripts/functions/origin: Set our own environment variable rather than relying on $HOME. 2004-01-21 Paul D. Smith * scripts/features/conditionals: Test arguments to ifn?def which contain whitespace (such as a function that is evaluated). Bug #7257. 2004-01-07 Paul D. Smith * scripts/features/order_only: Test order-only prerequisites in pattern rules (patch #2349). 2003-11-02 Paul D. Smith * scripts/functions/if: Test if on conditionals with trailing whitespace--bug #5798. * scripts/functions/eval: Test eval in a non-file context--bug #6195. 2003-04-19 Paul D. Smith * scripts/features/patspecific_vars: Test multiple patterns matching the same target--Bug #1405. 2003-04-09 Paul D. Smith * run_make_tests.pl (set_more_defaults): A new $port_type of 'OS/2' for (surprise!) OS/2. Also choose a wait time of 2 seconds for OS/2. 2003-03-28 Paul D. Smith * scripts/targets/SECONDARY: Test the "global" .SECONDARY (with not prerequisites)--Bug #2515. 2003-01-30 Paul D. Smith * scripts/features/targetvars: Test very long target-specific variable definition lines (longer than the default make buffer length). Tests patch # 1022. * scripts/functions/eval: Test very recursive $(eval ...) calls with simple variable expansion (bug #2238). * scripts/functions/word: Test error handling for word and wordlist functions (bug #2407). 2003-01-22 Paul D. Smith * scripts/functions/call: Test recursive argument masking (bug #1744). 2002-10-25 Paul D. Smith * scripts/functions/eval: Test using $(eval ...) inside conditionals (Bug #1516). 2002-10-14 Paul D. Smith * scripts/options/dash-t: Add a test for handling -t on targets with no commands (Bug #1418). 2002-10-13 Paul D. Smith * scripts/features/targetvars: Add a test for exporting target-specific vars (Bug #1391). 2002-10-05 Paul D. Smith * scripts/variables/automatic: Add tests for $$(@), $${@}, $${@D}, and $${@F}. 2002-09-23 Paul D. Smith * scripts/features/escape: Test handling of escaped comment characters in targets and prerequisites. 2002-09-18 Paul D. Smith * scripts/features/export: Test export/unexport of multiple variables in a single command. 2002-09-17 Paul D. Smith * scripts/features/targetvars: Tests for Bug #940: test target-specific and pattern-specific variables in conjunction with double-colon targets. 2002-09-10 Paul D. Smith * test_driver.pl (compare_output): Match the new format for time skew error messages. * scripts/features/export: Created. Add tests for export/unexport capabilities, including exporting/unexporting expanded variables. * scripts/features/conditionals: Add a test for expanded variables in ifdef conditionals. 2002-09-04 Paul D. Smith * scripts/features/reinvoke: Change touch/sleep combos to utouch invocations. * scripts/features/vpathgpath: Ditto. * scripts/features/vpathplus: Ditto. * scripts/options/dash-n: Ditto. * scripts/targets/INTERMEDIATE: Ditto. * scripts/targets/SECONDARY: Ditto. * scripts/options/dash-t: Added a test for the -t bug fixed by Henning Makholm. This test was also contributed by Henning. * scripts/misc/general4: Add a test suite for obscure algorithmic features of make. First test: make sure creation subdirectories as prerequisites of targets works properly. * scripts/misc/version: Remove this bogus test. 2002-08-07 Paul D. Smith * scripts/misc/general3: Add a test for makefiles that don't end in newlines. * scripts/variables/special: Create tests for the special variables (.VARIABLES and .TARGETS). Comment out .TARGETS test for now as it's not yet supported. 2002-08-01 Paul D. Smith * scripts/options/dash-B: Add a test for the new -B option. 2002-07-11 Paul D. Smith * run_make_tests.pl (valid_option): Add support for Valgrind. Use -valgrind option to the test suite. (set_more_defaults): Set up the file descriptor to capture Valgrind output. We have to unset its close-on-exec flag; we hardcode the value for F_SETFD (2) rather than load it; hopefully this will help us avoid breaking the Windows/DOS test suite. 2002-07-10 Paul D. Smith * scripts/variables/automatic: Add some tests for $$@, $$(@D), and $$(@F). * test_driver.pl (utouch): Create a new function that creates a file with a specific timestamp offset. Use of this function will let us avoid lots of annoying sleep() invocations in the tests just to get proper timestamping, which will make the tests run a lot faster. So far it's only used in the automatic test suite. 2002-07-09 Paul D. Smith * scripts/variables/automatic: Create a test for automatic variables. 2002-07-08 Paul D. Smith * scripts/features/order_only: Test new order-only prerequisites. 2002-07-07 Paul D. Smith * scripts/functions/eval: Test new function. * scripts/functions/value: Test new function. * scripts/variables/MAKEFILE_LIST: Test new variable. 2002-04-28 Paul D. Smith * scripts/functions/call: New test: transitive closure implementation using $(call ...) to test variable recursion. 2002-04-21 Paul D. Smith * test_driver.pl (compare_dir_tree): Ignore CVS and RCS directories in the script directories. 2001-05-02 Paul D. Smith * scripts/variables/flavors: Test define/endef scripts where only one of the command lines is quiet. 2000-06-22 Paul D. Smith * scripts/options/dash-q: New file; test the -q option. Includes a test for PR/1780. 2000-06-21 Paul D. Smith * scripts/features/targetvars: Added a test for PR/1709: allowing semicolons in target-specific variable values. 2000-06-19 Paul D. Smith * scripts/functions/addsuffix: Test for an empty final argument. Actually this bug might have happened for any function, but this one was handy. 2000-06-17 Eli Zaretskii * scripts/options/general: If parallel jobs are not supported, expect a warning message from Make. 2000-06-15 Eli Zaretskii * scripts/options/general: Don't try -jN with N != 1 if parallel jobs are not supported. 2000-05-24 Paul D. Smith * scripts/options/general: Test general option processing (PR/1716). 2000-04-11 Paul D. Smith * scripts/functions/strip: Test empty value to strip (PR/1689). 2000-04-08 Eli Zaretskii * scripts/features/reinvoke: Sleep before updating the target files in the first test, to ensure its time stamp really gets newer; otherwise Make might re-exec more than once. 2000-04-07 Eli Zaretskii * scripts/features/double_colon: Don't run the parallel tests if parallel jobs aren't supported. 2000-04-04 Paul D. Smith * scripts/functions/word: wordlist doesn't swap arguments anymore. 2000-03-27 Paul D. Smith * scripts/features/statipattrules: Test that static pattern rules whose prerequisite patterns resolve to empty strings throw an error (instead of dumping core). Fixes PR/1670. * scripts/features/reinvoke: Make more robust by touching "b" first, to ensure it's not newer than "a". Reported by Marco Franzen . * scripts/options/dash-n: Ditto. * scripts/functions/call: Whoops. The fix to PR/1527 caused recursive invocations of $(call ...) to break. I can't come up with any way to get both working at the same time, so I backed out the fix to 1527 and added a test case for recursive calls. This also tests the fix for PR/1610. * scripts/features/double_colon: Test that circular dependencies in double-colon rule sets are detected correctly (PR/1671). 2000-03-26 Paul D. Smith * scripts/targets/INTERMEDIATE: Test that make doesn't remove .INTERMEDIATE files when given on the command line (PR/1669). 2000-03-08 Paul D. Smith * scripts/options/dash-k: Add a test for error detection by multiple targets depending on the same prerequisite with -k. For PR/1634. 2000-02-07 Paul D. Smith * scripts/features/escape: Add a test for backslash-escaped spaces in a target name (PR/1586). 2000-02-04 Paul D. Smith * scripts/features/patspecific_vars: Add a test for pattern-specific target variables inherited from the parent target (PR/1407). 2000-02-02 Paul D. Smith * run_make_tests.pl (set_more_defaults): Hard-code the LANG to C to make sure sorting order, etc. is predictable. Reported by Andreas Jaeger . * run_make_tests.pl (set_more_defaults): Set the $wtime variable depending on the OS. Eli Zaretskii reports this seems to need to be *4* on DOS/Windows, not just 2. Keep it 1 for other systems. * scripts/features/vpathplus (touchfiles): Use the $wtime value instead of hardcoding 2. * scripts/targets/SECONDARY: Ditto. * scripts/targets/INTERMEDIATE: Ditto. 2000-01-27 Paul D. Smith * test_driver.pl (toplevel): Don't try to run test scripts which are really directories. 2000-01-23 Paul D. Smith * scripts/features/include: Remove a check; the fix caused more problems than the error, so I removed it and removed the test for it. 2000-01-11 Paul D. Smith * scripts/functions/call: Add a test for PR/1517 and PR/1527: make sure $(call ...) doesn't eval its arguments and that you can invoke foreach from it without looping forever. 1999-12-15 Paul D. Smith * scripts/targets/INTERMEDIATE: Add a test for PR/1423: make sure .INTERMEDIATE settings on files don't disable them as implicit intermediate possibilities. 1999-12-01 Paul D. Smith * scripts/features/double_colon: Add a test for PR/1476: Try double-colon rules as non-goal targets and during parallel builds to make sure they're handled serially. 1999-11-17 Paul D. Smith * scripts/functions/if: Add a test for PR/1429: put some text after an if-statement to make sure it works. * scripts/features/targetvars: Add a test for PR/1380: handling += in target-specific variable definitions correctly. 1999-10-15 Paul D. Smith * scripts/variables/MAKEFILES: This was really broken: it didn't test anything at all, really. Rewrote it, plus added a test for PR/1394. 1999-10-13 Paul D. Smith * scripts/options/dash-n: Add a test for PR/1379: "-n doesn't behave properly when used with recursive targets". 1999-10-08 Paul D. Smith * scripts/features/targetvars: Add a check for PR/1378: "Target-specific vars don't inherit correctly" 1999-09-29 Paul D. Smith * test_driver.pl (get_osname): Change $fancy_file_names to $short_filenames and reverse the logic. (run_each_test): Change test of non-existent $port_host to use $short_filenames--problem reported by Eli Zaretskii. 1999-09-23 Paul D. Smith * scripts/features/parallelism: Add a check to ensure that the jobserver works when we re-invoke. Also cleaned up the tests a little, reducing the number of rules we use so the test won't need as many "sleep" commands. 1999-09-16 Paul D. Smith * scripts/features/reinvoke: Remove invocations of "touch" in makefiles. See the comments on the touch function rewrite below. Note that UNIX touch behaves the same way if the file already exists: it sets the time to the _local_ time. We don't want this. This is probably a good tip for makefile writers in general, actually... where practical. * scripts/options/dash-l: Ditto. * scripts/options/dash-n: Ditto. * test_driver.pl (run_each_test): In retrospect, I don't like the .lN/.bN/.dN postfix required by DOS. So, for non-DOS systems I changed it back to use .log, .base, and .diff. * run_make_tests.pl (set_more_defaults): Move the check for the make pathname to here from set_defaults (that's too early since it happens before the command line processing). Create a new variable $port_type, calculated from $osname, to specify what kind of system we're running on. We should integrate the VOS stuff here, too. (valid_option): Comment out the workdir/-work stuff so people won't be fooled into thinking it works... someone needs to fix this, though! * scripts/functions/origin: Use $port_type instead of $osname. * scripts/functions/foreach: Ditto. * scripts/features/default_names: Ditto. 1999-09-15 Paul D. Smith * test_driver.pl (touch): Rewrite this function. Previously it used to use utime() to hard-set the time based on the current local clock, or, if the file didn't exist, it merely created it. This mirrors exactly what real UNIX touch does, but it fails badly on networked filesystems where the FS server clock is skewed from the local clock: normally modifying a file causes it to get a mod time based on the _server's_ clock. Hard-setting it based on the _local_ clock causes gratuitous errors and makes the tests unreliable except on local filesystems. The new function will simply modify the file, allowing the filesystem to set the mod time as it sees fit. * scripts/features/parallelism: The second test output could change depending on how fast some scripts completed; use "sleep" to force the order we want. * test_driver.pl (toplevel): A bug in Perl 5.000 to Perl 5.004 means that "%ENV = ();" doesn't do the right thing. This worked in Perl 4 and was fixed in Perl 5.004_01, but use a loop to delete the environment rather than require specific versions. * run_make_tests.pl (set_more_defaults): Don't use Perl 5 s/// modifier "s", so the tests will run with Perl 4. (set_more_defaults): Set $pure_log to empty if there's no -logfile option in PURIFYOPTIONS. (setup_for_test): Don't remove any logs unless $pure_log is set. 1999-09-15 Eli Zaretskii * scripts/features/reinvoke: Put the SHELL definition in the right test makefile. 1999-09-15 Paul D. Smith ChangeLog file for the test suite created. Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006 Free Software Foundation, Inc.
