127 Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use
128 of C<git bisect> as much as possible. With one command (and no other files)
129 it's easy to find out
135 Which commit caused this example code to break?
139 Which commit caused this example code to start working?
143 Which commit added the first file to match this regex?
147 Which commit removed the last file to match this regex?
151 usually without needing to know which versions of perl to use as start and
154 By default F<bisect.pl> will process all options, then use the rest of the
155 command line as arguments to list C<system> to run a test case. By default,
156 the test case should pass (exit with 0) on earlier perls, and fail (exit
157 non-zero) on I<blead> (note that running most of perl's test files directly
158 won't do this, you'll need to run them through a harness to get the proper
159 error code). F<bisect.pl> will use F<bisect-runner.pl> to find the earliest
160 stable perl version on which the test case passes, check that it fails on
161 blead, and then use F<bisect-runner.pl> with C<git bisect run> to find the
162 commit which caused the failure.
164 Because the test case is the complete argument to C<system>, it is easy to
165 run something other than the F<perl> built, if necessary. If you need to run
166 the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>.
167 As a special case, if the first argument of the test case is a readable file
168 (whether executable or not), matching C<qr{\A#!./(?:mini)?perl\b}> then it
169 will have C<./perl> <-Ilib> (or C<./miniperl>) prepended to it.
171 You need a clean checkout to run a bisect, and you can't use the checkout
172 which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
173 a revision before F<Porting/bisect-runner.pl> was added, which
174 C<git bisect run> needs). If your working checkout is called F<perl>, the
175 simplest solution is to make a local clone, and run from that. I<i.e.>:
180 ../perl/Porting/bisect.pl ...
182 By default, F<bisect-runner.pl> will automatically disable the build of
183 L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical
184 to patch DB_File 1.70 and earlier to build with current Berkeley DB headers.
185 (ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.)
186 If your F<db.h> is old enough you can override this with C<-Unoextensions>.
194 --start I<commit-ish>
196 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
197 else C<git> understands as a revision). If not specified, F<bisect.pl> will
198 search stable .0 perl releases until it finds one where the test case passes
199 (5.16.0 at the time of writing). The default is to search from 5.002 to the
200 most recent tagged stable release. If F<bisect.pl> detects that the
201 checkout is on a case insensitive file system, it will search from 5.005 to
202 the most recent tagged stable release. Only .0 stable releases are used
203 because these are the only stable releases that are parents of blead, and
204 hence suitable for a bisect run.
210 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
217 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
218 this should be one of
226 Just run F<./Configure>
232 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
244 Use F<miniperl> to build F<lib/Config.pm>
250 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
251 is simple XS module present since 5.000, this provides a fast test of
252 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
253 hence this target will not build F<perl>.
259 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
260 F<ext>. XS modules (such as L<Fcntl>) are not built.
266 Build everything needed to run the tests. This is the default if we're
267 running test code, but is time consuming, as it means building all
268 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
269 is automatically substituted. For very old F<Makefile>s, C<make test> is
270 run, as there is no target provided to just get things ready, and for 5.004
271 and earlier the tests run very quickly.
277 --one-liner 'code to run'
283 Example code to run, just like you'd use with C<perl -e>.
285 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
286 or F<./miniperl> if I<target> is C<miniperl>.
288 (Usually you'll use C<-e> instead of providing a test case in the
289 non-option arguments to F<bisect.pl>)
291 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
292 which interferes with detecting errors in the example code itself.
298 Add C<-c> to the command line, to cause perl to exit after syntax checking.
304 Add C<-l> to the command line with C<-e>
306 This will automatically append a newline to every output line of your testcase.
307 Note that you can't specify an argument to F<perl>'s C<-l> with this, as it's
308 not feasible to emulate F<perl>'s somewhat quirky switch parsing with
309 L<Getopt::Long>. If you need the full flexibility of C<-l>, you need to write
310 a full test case, instead of using C<bisect.pl>'s C<-e> shortcut.
316 Add C<-w> to the command line with C<-e>
318 It's not valid to pass C<-c>, C<-l> or C<-w> to C<bisect.pl> unless you are
325 The test case should fail for the I<start> revision, and pass for the I<end>
326 revision. The bisect run will find the first commit where it passes.
330 -D I<config_arg=value>
338 -A I<config_arg=value>
340 Arguments (C<-A>, C<-D>, C<-U>) to pass to F<Configure>. For example,
342 -Dnoextensions=Encode
344 -Accflags=-DNO_MATHOMS
346 Repeated C<-A> arguments are passed
347 through as is. C<-D> and C<-U> are processed in order, and override
348 previous settings for the same parameter. F<bisect-runner.pl> emulates
349 C<-Dnoextensions> when F<Configure> itself does not provide it, as it's
350 often very useful to be able to disable some XS extensions.
356 The C<make> command to use. If this not set, F<make> is used. If this is
357 set, it also adds a C<-Dmake=...> else some recursive make invocations
358 in extensions may fail. Typically one would use this as C<--make gmake>
359 to use F<gmake> in place of the system F<make>.
369 Number of C<make> jobs to run in parallel. A value of 0 suppresses
370 parallelism. If F</proc/cpuinfo> exists and can be parsed, or F</sbin/sysctl>
371 exists and reports C<hw.ncpu>, or F</usr/bin/getconf> exists and reports
372 C<_NPROCESSORS_ONLN> defaults to 1 + I<number of CPUs>. On HP-UX with the
373 system make defaults to 0, otherwise defaults to 2.
383 Instead of running a test program to determine I<pass> or I<fail>,
384 C<--match> will pass if the given regex matches, and hence search for the
385 commit that removes the last matching file. C<--no-match> inverts the test,
386 to search for the first commit that adds files that match.
388 The remaining command line arguments are treated as glob patterns for files
389 to match against. If none are specified, then they default as follows:
395 If no I<target> is specified, the match is against all files in the
396 repository (which is fast).
400 If a I<target> is specified, that target is built, and the match is against
401 only the built files.
405 Treating the command line arguments as glob patterns should not cause
406 problems, as the perl distribution has never shipped or built files with
407 names that contain characters which are globbing metacharacters.
409 Anything which is not a readable file is ignored, instead of generating an
410 error. (If you want an error, run C<grep> or C<ack> as a test case). This
411 permits one to easily search in a file that changed its name. For example:
413 .../Porting/bisect.pl --match 'Pod.*Functions' 'pod/buildtoc*'
415 C<--no-match ...> is implemented as C<--expect-fail --match ...>
421 Run the test program under C<valgrind>. If you need to test for memory
422 errors when parsing invalid programs, the default parser fail exit code of
423 255 will always override C<valgrind>, so try putting the test case invalid
424 code inside a I<string> C<eval>, so that the perl interpreter will exit with 0.
425 (Be sure to check the output of $@, to avoid missing mistakes such as
426 unintended C<eval> failures due to incorrect C<@INC>)
428 Specifically, this option prepends C<valgrind> C<--error-exitcode=124> to
429 the command line that runs the testcase, to cause valgrind to exit non-zero
430 if it detects errors, with the assumption that the test program itself
431 always exits with zero. If you require more flexibility than this, either
432 specify your C<valgrind> invocation explicitly as part of the test case, or
433 use a wrapper script to control the command line or massage the exit codes.
439 Test that the build completes, without running any test case.
441 By default, if the build for the desired I<target> fails to complete,
442 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
443 being that one wants to find a commit which changed state "builds && passes"
444 to "builds && fails". If instead one is interested in which commit broke the
445 build (possibly for particular F<Configure> options), use I<--test-build>
446 to treat a build failure as a failure, not a "skip".
448 Often this option isn't as useful as it first seems, because I<any> build
449 failure will be reported to C<git bisect> as a failure, not just the failure
450 that you're interested in. Generally, to debug a particular problem, it's
451 more useful to use a I<target> that builds properly at the point of interest,
452 and then a test case that runs C<make>. For example:
454 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
455 --expect-fail --force-manifest --target=miniperl make perl
457 will find the first revision capable of building L<DynaLoader> and then
458 F<perl>, without becoming confused by revisions where F<miniperl> won't
465 By default, a build will "skip" if any files listed in F<MANIFEST> are not
466 present. Usually this is useful, as it avoids false-failures. However, there
467 are some long ranges of commits where listed files are missing, which can
468 cause a bisect to abort because all that remain are skipped revisions.
470 In these cases, particularly if the test case uses F<miniperl> and no modules,
471 it may be more useful to force the build to continue, even if files
472 F<MANIFEST> are missing.
478 Run C<make regen_headers> before building F<miniperl>. This may fix a build
479 that otherwise would skip because the generated headers at that revision
480 are stale. It's not the default because it conceals this error in the true
481 state of such revisions.
487 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
493 Run the testcase with the given timeout. If this is exceeded, kill it (and
494 by default all its children), and treat it as a failure.
500 Run the testcase in its own process group. Specifically, call C<setpgrp 0, 0>
501 just before C<exec>-ing the user testcase. The default is not to set the
502 process group, unless a timeout is used.
508 F<bisect-runner.pl> will minimally patch various files on a platform and
509 version dependent basis to get the build to complete. Normally it defers
510 doing this as long as possible - C<.SH> files aren't patched until after
511 F<Configure> is run, and C<C> and C<XS> code isn't patched until after
512 F<miniperl> is built. If C<--all-fixups> is specified, all the fixups are
513 done before running C<Configure>. In rare cases adding this may cause a
514 bisect to abort, because an inapplicable patch or other fixup is attempted
515 for a revision which would usually have already I<skip>ed. If this happens,
516 please report it as a bug, giving the OS and problem revision.
526 Specify a file containing a patch or other fixup for the source code. The
527 action to take depends on the first line of the fixup file
535 If the first line starts C<#!perl> then the file is run using C<$^X>
541 If a shebang line is present the file is executed using C<system>
545 C<I<filename> =~ /I<pattern>/>
549 C<I<filename> !~ /I<pattern>/>
551 If I<filename> does not exist then the fixup file's contents are ignored.
552 Otherwise, for C<=~>, if it contains a line matching I<pattern>, then the
553 file is fed to C<patch -p1> on standard input. For C<=~>, the patch is
554 applied if no lines match the pattern.
556 As the empty pattern in Perl is a special case (it matches the most recent
557 sucessful match) which is not useful here, an the treatment of empty pattern
558 is special-cased. C<I<filename> =~ //> applies the patch if filename is
559 present. C<I<filename> !~ //> applies the patch if filename missing. This
560 makes it easy to unconditionally apply patches to files, and to use a patch
561 as a way of creating a new file.
565 Otherwise, the file is assumed to be a patch, and always applied.
569 I<early-fixup>s are applied before F<./Configure> is run. I<late-fixup>s are
570 applied just after F<./Configure> is run.
572 These options can be specified more than once. I<file> is actually expanded
573 as a glob pattern. Globs that do not match are errors, as are missing files.
579 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
580 to use F<bisect-runner.pl> to build the current particular perl revision for
581 interactive testing, or for debugging F<bisect-runner.pl>.
583 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
589 Test that all stable (.0) revisions can be built. By default, attempts to
590 build I<blead>, then tagged stable releases in reverse order down to
591 I<perl-5.002> (or I<perl5.005> on a case insensitive file system). Stops at
592 the first failure, without cleaning the checkout. Use I<--start> to specify
593 the earliest revision to test, I<--end> to specify the most recent. Useful
594 for validating a new OS/CPU/compiler combination. For example
596 ../perl/Porting/bisect.pl --validate -le 'print "Hello from $]"'
598 If no testcase is specified, the default is to use F<t/TEST> to run
605 Validate the options and arguments, and exit silently if they are valid.
611 Validate that the test case isn't an executable file with a
612 C<#!/usr/bin/perl> line (or similar). As F<bisect-runner.pl> does B<not>
613 automatically prepend C<./perl> to the test case, a I<#!> line specifying an
614 external F<perl> binary will cause the test case to always run with I<that>
615 F<perl>, not the F<perl> built by the bisect runner. Likely this is not what
616 you wanted. If your test case is actually a wrapper script to run other
617 commands, you should run it with an explicit interpreter, to be clear. For
618 example, instead of C<../perl/Porting/bisect.pl ~/test/testcase.pl> you'd
619 run C<../perl/Porting/bisect.pl /usr/bin/perl ~/test/testcase.pl>
625 Revision to use when checking out known-good recent versions of files,
626 such as F<makedepend.SH>. F<bisect-runner.pl> defaults this to I<blead>,
627 but F<bisect.pl> will default it to the most recent stable release.
