190 Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use
191 of C<git bisect> as much as possible. With one command (and no other files)
192 it's easy to find out
198 Which commit caused this example code to break?
202 Which commit caused this example code to start working?
206 Which commit added the first file to match this regex?
210 Which commit removed the last file to match this regex?
214 usually without needing to know which versions of perl to use as start and
217 By default F<bisect.pl> will process all options, then use the rest of the
218 command line as arguments to list C<system> to run a test case. By default,
219 the test case should pass (exit with 0) on earlier perls, and fail (exit
220 non-zero) on I<blead>. F<bisect.pl> will use F<bisect-runner.pl> to find the
221 earliest stable perl version on which the test case passes, check that it
222 fails on blead, and then use F<bisect-runner.pl> with C<git bisect run> to
223 find the commit which caused the failure.
225 Many of perl's own test scripts exit 0 even if their TAP reports test
226 failures, and some need particular setup (such as running from the right
227 directory, or adding C<-T> to the command line). Hence if you want to bisect
228 a test script, you can specify it with the I<--target> option, and it will
229 be invoked using F<t/TEST> which performs all the setup, and exits non-zero
230 if the TAP reports failures. This works for any file ending C<.t>, so you can
231 use it with a file outside of the working checkout, for example to test a
232 particular version of a test script, as a path inside the repository will
233 (of course) be testing the version of the script checked out for the current
234 revision, which may be too early to have the test you are interested in.
236 Because the test case is the complete argument to C<system>, it is easy to
237 run something other than the F<perl> built, if necessary. If you need to run
238 the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>.
239 As a special case, if the first argument of the test case is a readable file
240 (whether executable or not), matching C<qr{\A#!./(?:mini)?perl\b}> then it
241 will have C<./perl> <-Ilib> (or C<./miniperl>) prepended to it.
243 You need a clean checkout to run a bisect. You can use the checkout
244 containing F<Porting/bisect.pl> if you wish - in this case
245 F<Porting/bisect.pl> will copy F<Porting/bisect-runner.pl> to a temporary
246 file generated by C<File::Temp::tempfile()>. If doing this, beware that when
247 the bisect ends (or you abort it) then your checkout is no longer at
248 C<blead>, so you will need to C<git checkout blead> before restarting, to
249 get the current version of F<Porting/bisect.pl> again. It's often easier
250 either to copy F<Porting/bisect.pl> and F<Porting/bisect-runner.pl> to
251 another directory (I<e.g.> F<~/bin>, if you have one), or to create a second
252 git repository for running bisect. To create a second local repository, if
253 your working checkout is called F<perl>, a simple solution is to make a
254 local clone, and run from that. I<i.e.>:
259 ../perl/Porting/bisect.pl ...
261 By default, F<bisect-runner.pl> will automatically disable the build of
262 L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical
263 to patch DB_File 1.70 and earlier to build with current Berkeley DB headers.
264 (ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.)
265 If your F<db.h> is old enough you can override this with C<-Unoextensions>.
273 --start I<commit-ish>
275 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
276 else C<git> understands as a revision). If not specified, F<bisect.pl> will
277 search stable .0 perl releases until it finds one where the test case
278 passes. The default is to search from 5.002 to the most recent tagged stable
279 release (v5.18.0 at the time of writing). If F<bisect.pl> detects that the
280 checkout is on a case insensitive file system, it will search from 5.005 to
281 the most recent tagged stable release. Only .0 stable releases are used
282 because these are the only stable releases that are parents of blead, and
283 hence suitable for a bisect run.
289 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
296 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
297 this should be one of
305 Don't build anything - just run the user test case against a clean checkout.
306 Using this gives a couple of features that a plain C<git bisect run> can't
307 offer - automatic start revision detection, and test case C<--timeout>.
313 Just run F<./Configure>
319 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
331 Use F<miniperl> to build F<lib/Config.pm>
337 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
338 is simple XS module present since 5.000, this provides a fast test of
339 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
340 hence this target will not build F<perl>.
346 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
347 F<ext>. XS modules (such as L<Fcntl>) are not built.
353 Build everything needed to run the tests. This is the default if we're
354 running test code, but is time consuming, as it means building all
355 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
356 is automatically substituted. For very old F<Makefile>s, C<make test> is
357 run, as there is no target provided to just get things ready, and for 5.004
358 and earlier the tests run very quickly.
364 Build everything needed to run the tests, and then run this test script using
365 F<t/TEST>. This is actually implemented internally by using the target
366 I<test_prep>, and setting the test case to "sh", "-c", "cd t && ./TEST ..."
372 --one-liner 'code to run'
378 Example code to run, just like you'd use with C<perl -e>.
380 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
381 or F<./miniperl> if I<target> is C<miniperl>.
383 (Usually you'll use C<-e> instead of providing a test case in the
384 non-option arguments to F<bisect.pl>. You can repeat C<-e> on the command
385 line, just like you can with C<perl>)
387 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
388 which interferes with detecting errors in the example code itself.
394 Add C<-c> to the command line, to cause perl to exit after syntax checking.
400 Add C<-l> to the command line with C<-e>
402 This will automatically append a newline to every output line of your testcase.
403 Note that you can't specify an argument to F<perl>'s C<-l> with this, as it's
404 not feasible to emulate F<perl>'s somewhat quirky switch parsing with
405 L<Getopt::Long>. If you need the full flexibility of C<-l>, you need to write
406 a full test case, instead of using C<bisect.pl>'s C<-e> shortcut.
412 Add C<-w> to the command line with C<-e>
414 It's not valid to pass C<-c>, C<-l> or C<-w> to C<bisect.pl> unless you are
421 The test case should fail for the I<start> revision, and pass for the I<end>
422 revision. The bisect run will find the first commit where it passes.
428 Treat any non-crash as success, any crash as failure. (Crashing defined
429 as exiting with a signal or a core dump.)
433 -D I<config_arg=value>
441 -A I<config_arg=value>
443 Arguments (C<-A>, C<-D>, C<-U>) to pass to F<Configure>. The C<-D>, C<-A> and
444 C<-U> switches should be spelled as if you were normally giving them to
445 F<./Configure>. For example,
447 -Dnoextensions=Encode
449 -Accflags=-DNO_MATHOMS
451 Repeated C<-A> arguments are passed
452 through as is. C<-D> and C<-U> are processed in order, and override
453 previous settings for the same parameter. F<bisect-runner.pl> emulates
454 C<-Dnoextensions> when F<Configure> itself does not provide it, as it's
455 often very useful to be able to disable some XS extensions.
461 The C<make> command to use. If this not set, F<make> is used. If this is
462 set, it also adds a C<-Dmake=...> else some recursive make invocations
463 in extensions may fail. Typically one would use this as C<--make gmake>
464 to use F<gmake> in place of the system F<make>.
474 Number of C<make> jobs to run in parallel. A value of 0 suppresses
475 parallelism. If F</proc/cpuinfo> exists and can be parsed, or F</sbin/sysctl>
476 exists and reports C<hw.ncpu>, or F</usr/bin/getconf> exists and reports
477 C<_NPROCESSORS_ONLN> defaults to 1 + I<number of CPUs>. On HP-UX with the
478 system make defaults to 0, otherwise defaults to 2.
488 Instead of running a test program to determine I<pass> or I<fail>,
489 C<--match> will pass if the given regex matches, and hence search for the
490 commit that removes the last matching file. C<--no-match> inverts the test,
491 to search for the first commit that adds files that match.
493 The remaining command line arguments are treated as glob patterns for files
494 to match against. If none are specified, then they default as follows:
500 If no I<target> is specified, the match is against all files in the
501 repository (which is fast).
505 If a I<target> is specified, that target is built, and the match is against
506 only the built files.
510 Treating the command line arguments as glob patterns should not cause
511 problems, as the perl distribution has never shipped or built files with
512 names that contain characters which are globbing metacharacters.
514 Anything which is not a readable file is ignored, instead of generating an
515 error. (If you want an error, run C<grep> or C<ack> as a test case). This
516 permits one to easily search in a file that changed its name. For example:
518 .../Porting/bisect.pl --match 'Pod.*Functions' 'pod/buildtoc*'
520 C<--no-match ...> is implemented as C<--expect-fail --match ...>
526 Run the test program under C<valgrind>. If you need to test for memory
527 errors when parsing invalid programs, the default parser fail exit code of
528 255 will always override C<valgrind>, so try putting the test case invalid
529 code inside a I<string> C<eval>, so that the perl interpreter will exit with 0.
530 (Be sure to check the output of $@, to avoid missing mistakes such as
531 unintended C<eval> failures due to incorrect C<@INC>)
533 Specifically, this option prepends C<valgrind> C<--error-exitcode=124> to
534 the command line that runs the testcase, to cause valgrind to exit non-zero
535 if it detects errors, with the assumption that the test program itself
536 always exits with zero. If you require more flexibility than this, either
537 specify your C<valgrind> invocation explicitly as part of the test case, or
538 use a wrapper script to control the command line or massage the exit codes.
540 In order for the test program to be seen as a perl script to valgrind
541 (rather than a shell script), the first line must be one of the following
550 Test that the build completes, without running any test case.
552 By default, if the build for the desired I<target> fails to complete,
553 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
554 being that one wants to find a commit which changed state "builds && passes"
555 to "builds && fails". If instead one is interested in which commit broke the
556 build (possibly for particular F<Configure> options), use I<--test-build>
557 to treat a build failure as a failure, not a "skip".
559 Often this option isn't as useful as it first seems, because I<any> build
560 failure will be reported to C<git bisect> as a failure, not just the failure
561 that you're interested in. Generally, to debug a particular problem, it's
562 more useful to use a I<target> that builds properly at the point of interest,
563 and then a test case that runs C<make>. For example:
565 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
566 --expect-fail --force-manifest --target=miniperl make perl
568 will find the first revision capable of building L<DynaLoader> and then
569 F<perl>, without becoming confused by revisions where F<miniperl> won't
574 --module module1,module2,...
576 Install this (or these) module(s), die when it (the last of those)
577 cannot be updated to the current version.
579 Misnomer. the argument can be any argument that can be passed to CPAN
580 shell's install command. B<But>: since we only have the uptodate
581 command to verify that an install has taken place, we are unable to
582 determine success for arguments like
583 MSCHWERN/Test-Simple-1.005000_005.tar.gz.
585 In so far, it is not such a misnomer.
587 Note that this and I<--with-module> will both require a C<CPAN::MyConfig>.
588 If F<$ENV{HOME}/.cpan/CPAN/MyConfig.pm> does not exist, a CPAN shell will
589 be started up for you so you can configure one. Feel free to let
590 CPAN pick defaults for you. Enter 'quit' when you are done, and
591 then everything should be all set. Alternatively, you may
592 specify a custom C<CPAN::MyConfig> by using I<--cpan-config-dir>.
594 Also, if you want to bisect a module that needs a display (like
595 TK) and you don't want random screens appearing and disappearing
596 on your computer while you're working, you can do something like
601 $ while true; do date ; if ! ps auxww | grep -v grep \
602 | grep -q Xvfb; then Xvfb :121 & fi; echo -n 'sleeping 60 '; \
607 DISPLAY=":121" .../Porting/bisect.pl --module=TK
609 (Some display alternatives are vncserver and Xnest.)
613 --with-module module1,module2,...
615 Like I<--module> above, except this simply installs the requested
616 modules and they can then be used in other tests.
620 .../Porting/bisect.pl --with-module=Moose -e 'use Moose; ...'
626 Use in conjunction with I<--with-module> to install the modules without
627 running their tests. This can be a big time saver.
631 .../Porting/bisect.pl --with-module=Moose --no-module-tests \
638 This is like I<--module>, but just runs the module's tests, instead of
641 WARNING: This is a somewhat experimental option, known to work on recent
642 CPAN shell versions. If you use this option and strange things happen,
645 Usually, you can just use I<--module>, but if you are getting inconsistent
646 installation failures and you just want to see when the tests started
647 failing, you might find this option useful.
651 --cpan-config-dir /home/blah/custom
653 If defined, this will cause L<CPAN> to look for F<CPAN/MyConfig.pm> inside of
654 the specified directory, instead of using the default config of
655 F<$ENV{HOME}/.cpan/>.
657 If no default config exists, a L<CPAN> shell will be fired up for you to
658 configure things. Letting L<CPAN> automatically configure things for you
659 should work well enough. You probably want to choose I<manual> instead of
660 I<local::lib> if it asks. When you're finished with configuration, just
661 type I<q> and hit I<ENTER> and the bisect should continue.
667 By default, a build will "skip" if any files listed in F<MANIFEST> are not
668 present. Usually this is useful, as it avoids false-failures. However, there
669 are some long ranges of commits where listed files are missing, which can
670 cause a bisect to abort because all that remain are skipped revisions.
672 In these cases, particularly if the test case uses F<miniperl> and no modules,
673 it may be more useful to force the build to continue, even if files
674 F<MANIFEST> are missing.
680 Run C<make regen_headers> before building F<miniperl>. This may fix a build
681 that otherwise would skip because the generated headers at that revision
682 are stale. It's not the default because it conceals this error in the true
683 state of such revisions.
689 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
695 Run the testcase with the given timeout. If this is exceeded, kill it (and
696 by default all its children), and treat it as a failure.
702 Run the testcase in its own process group. Specifically, call C<setpgrp 0, 0>
703 just before C<exec>-ing the user testcase. The default is not to set the
704 process group, unless a timeout is used.
710 F<bisect-runner.pl> will minimally patch various files on a platform and
711 version dependent basis to get the build to complete. Normally it defers
712 doing this as long as possible - C<.SH> files aren't patched until after
713 F<Configure> is run, and C<C> and C<XS> code isn't patched until after
714 F<miniperl> is built. If C<--all-fixups> is specified, all the fixups are
715 done before running C<Configure>. In rare cases adding this may cause a
716 bisect to abort, because an inapplicable patch or other fixup is attempted
717 for a revision which would usually have already I<skip>ped. If this happens,
718 please report it as a bug, giving the OS and problem revision.
728 Specify a file containing a patch or other fixup for the source code. The
729 action to take depends on the first line of the fixup file
737 If the first line starts C<#!perl> then the file is run using C<$^X>
743 If a shebang line is present the file is executed using C<system>
747 C<I<filename> =~ /I<pattern>/>
751 C<I<filename> !~ /I<pattern>/>
753 If I<filename> does not exist then the fixup file's contents are ignored.
754 Otherwise, for C<=~>, if it contains a line matching I<pattern>, then the
755 file is fed to C<patch -p1> on standard input. For C<=~>, the patch is
756 applied if no lines match the pattern.
758 As the empty pattern in Perl is a special case (it matches the most recent
759 successful match) which is not useful here, the treatment of an empty pattern
760 is special-cased. C<I<filename> =~ //> applies the patch if filename is
761 present. C<I<filename> !~ //> applies the patch if filename missing. This
762 makes it easy to unconditionally apply patches to files, and to use a patch
763 as a way of creating a new file.
767 Otherwise, the file is assumed to be a patch, and always applied.
771 I<early-fixup>s are applied before F<./Configure> is run. I<late-fixup>s are
772 applied just after F<./Configure> is run.
774 These options can be specified more than once. I<file> is actually expanded
775 as a glob pattern. Globs that do not match are errors, as are missing files.
781 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
782 to use F<bisect-runner.pl> to build the current particular perl revision for
783 interactive testing, or for debugging F<bisect-runner.pl>.
785 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
791 Test that all stable (.0) revisions can be built. By default, attempts to
792 build I<blead>, then tagged stable releases in reverse order down to
793 I<perl-5.002> (or I<perl5.005> on a case insensitive file system). Stops at
794 the first failure, without cleaning the checkout. Use I<--start> to specify
795 the earliest revision to test, I<--end> to specify the most recent. Useful
796 for validating a new OS/CPU/compiler combination. For example
798 ../perl/Porting/bisect.pl --validate -le 'print "Hello from $]"'
800 If no testcase is specified, the default is to use F<t/TEST> to run
807 Validate the options and arguments, and exit silently if they are valid.
813 Validate that the test case isn't an executable file with a
814 C<#!/usr/bin/perl> line (or similar). As F<bisect-runner.pl> does B<not>
815 automatically prepend C<./perl> to the test case, a I<#!> line specifying an
816 external F<perl> binary will cause the test case to always run with I<that>
817 F<perl>, not the F<perl> built by the bisect runner. Likely this is not what
818 you wanted. If your test case is actually a wrapper script to run other
819 commands, you should run it with an explicit interpreter, to be clear. For
820 example, instead of C<../perl/Porting/bisect.pl ~/test/testcase.pl> you'd
821 run C<../perl/Porting/bisect.pl /usr/bin/perl ~/test/testcase.pl>
827 Revision to use when checking out known-good recent versions of files,
828 such as F<makedepend.SH>. F<bisect-runner.pl> defaults this to I<blead>,
829 but F<bisect.pl> will default it to the most recent stable release.
843 Display the usage information and exit.

930 =head2 When did perl start failing to build on a certain platform using C<g++> as the C-compiler?
936 On NetBSD-8.0, C<perl> had never been smoke-tested using C<g++> as the
937 C-compiler. Once this was done, it became evident that changes in that
938 version of the operating system's code were incompatible with some C<perl>
939 source written long before that OS version was ever released!
943 Bisection range was first narrowed using existing builds at release tags.
944 Then, bisection specified the C-compiler via C<Configure>-style switch and
945 used C<--test-build> to identify the commit which "broke" the build.
