121 Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use
122 of C<git bisect> as much as possible. With one command (and no other files)
123 it's easy to find out
129 Which commit caused this example code to break?
133 Which commit caused this example code to start working?
137 Which commit added the first file to match this regex?
141 Which commit removed the last file to match this regex?
145 usually without needing to know which versions of perl to use as start and
148 By default F<bisect.pl> will process all options, then use the rest of the
149 command line as arguments to list C<system> to run a test case. By default,
150 the test case should pass (exit with 0) on earlier perls, and fail (exit
151 non-zero) on I<blead> (note that running most of perl's test files directly
152 won't do this, you'll need to run them through a harness to get the proper
153 error code). F<bisect.pl> will use F<bisect-runner.pl> to find the earliest
154 stable perl version on which the test case passes, check that it fails on
155 blead, and then use F<bisect-runner.pl> with C<git bisect run> to find the
156 commit which caused the failure.
158 Because the test case is the complete argument to C<system>, it is easy to
159 run something other than the F<perl> built, if necessary. If you need to run
160 the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>.
161 As a special case, if the first argument of the test case is a readable file
162 (whether executable or not), matching C<qr{\A#!./(?:mini)?perl\b}> then it
163 will have C<./perl> <-Ilib> (or C<./miniperl>) prepended to it.
165 You need a clean checkout to run a bisect, and you can't use the checkout
166 which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
167 a revision before F<Porting/bisect-runner.pl> was added, which
168 C<git bisect run> needs). If your working checkout is called F<perl>, the
169 simplest solution is to make a local clone, and run from that. I<i.e.>:
174 ../perl/Porting/bisect.pl ...
176 By default, F<bisect-runner.pl> will automatically disable the build of
177 L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical
178 to patch DB_File 1.70 and earlier to build with current Berkeley DB headers.
179 (ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.)
180 If your F<db.h> is old enough you can override this with C<-Unoextensions>.
188 --start I<commit-ish>
190 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
191 else C<git> understands as a revision). If not specified, F<bisect.pl> will
192 search stable perl releases until it finds one where the test case passes.
193 The default is to search from 5.002 to 5.14.0. If F<bisect.pl> detects that
194 the checkout is on a case insensitive file system, it will search from
201 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
208 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
209 this should be one of
217 Just run F<./Configure>
223 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
235 Use F<miniperl> to build F<lib/Config.pm>
241 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
242 is simple XS module present since 5.000, this provides a fast test of
243 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
244 hence this target will not build F<perl>.
250 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
251 F<ext>. XS modules (such as L<Fcntl>) are not built.
257 Build everything needed to run the tests. This is the default if we're
258 running test code, but is time consuming, as it means building all
259 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
260 is automatically substituted. For very old F<Makefile>s, C<make test> is
261 run, as there is no target provided to just get things ready, and for 5.004
262 and earlier the tests run very quickly.
268 --one-liner 'code to run'
274 Example code to run, just like you'd use with C<perl -e>.
276 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
277 or F<./miniperl> if I<target> is C<miniperl>.
279 (Usually you'll use C<-e> instead of providing a test case in the
280 non-option arguments to F<bisect.pl>)
282 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
283 which interferes with detecting errors in the example code itself.
289 Add C<-c> to the command line, to cause perl to exit after syntax checking.
295 Add C<-l> to the command line with C<-e>
297 This will automatically append a newline to every output line of your testcase.
298 Note that you can't specify an argument to F<perl>'s C<-l> with this, as it's
299 not feasible to emulate F<perl>'s somewhat quirky switch parsing with
300 L<Getopt::Long>. If you need the full flexibility of C<-l>, you need to write
301 a full test case, instead of using C<bisect.pl>'s C<-e> shortcut.
307 Add C<-w> to the command line with C<-e>
309 It's not valid to pass C<-c>, C<-l> or C<-w> to C<bisect.pl> unless you are
316 The test case should fail for the I<start> revision, and pass for the I<end>
317 revision. The bisect run will find the first commit where it passes.
321 -D I<config_arg=value>
329 -A I<config_arg=value>
331 Arguments (C<-A>, C<-D>, C<-U>) to pass to F<Configure>. For example,
333 -Dnoextensions=Encode
335 -Accflags=-DNO_MATHOMS
337 Repeated C<-A> arguments are passed
338 through as is. C<-D> and C<-U> are processed in order, and override
339 previous settings for the same parameter. F<bisect-runner.pl> emulates
340 C<-Dnoextensions> when F<Configure> itself does not provide it, as it's
341 often very useful to be able to disable some XS extensions.
347 The C<make> command to use. If this not set, F<make> is used. If this is
348 set, it also adds a C<-Dmake=...> else some recursive make invocations
349 in extensions may fail. Typically one would use this as C<--make gmake>
350 to use F<gmake> in place of the system F<make>.
360 Number of C<make> jobs to run in parallel. A value of 0 suppresses
361 parallelism. If F</proc/cpuinfo> exists and can be parsed, or F</sbin/sysctl>
362 exists and reports C<hw.ncpu>, or F</usr/bin/getconf> exists and reports
363 C<_NPROCESSORS_ONLN> defaults to 1 + I<number of CPUs>. On HP-UX with the
364 system make defaults to 0, otherwise defaults to 2.
374 Instead of running a test program to determine I<pass> or I<fail>,
375 C<--match> will pass if the given regex matches, and hence search for the
376 commit that removes the last matching file. C<--no-match> inverts the test,
377 to search for the first commit that adds files that match.
379 The remaining command line arguments are treated as glob patterns for files
380 to match against. If none are specified, then they default as follows:
386 If no I<target> is specified, the match is against all files in the
387 repository (which is fast).
391 If a I<target> is specified, that target is built, and the match is against
392 only the built files.
396 Treating the command line arguments as glob patterns should not cause
397 problems, as the perl distribution has never shipped or built files with
398 names that contain characters which are globbing metacharacters.
400 Anything which is not a readable file is ignored, instead of generating an
401 error. (If you want an error, run C<grep> or C<ack> as a test case). This
402 permits one to easily search in a file that changed its name. For example:
404 .../Porting/bisect.pl --match 'Pod.*Functions' 'pod/buildtoc*'
406 C<--no-match ...> is implemented as C<--expect-fail --match ...>
412 Run the test program under C<valgrind>. If you need to test for memory
413 errors when parsing invalid programs, the default parser fail exit code of
414 255 will always override C<valgrind>, so try putting the test case invalid
415 code inside a I<string> C<eval>, so that the perl interpreter will exit with 0.
416 (Be sure to check the output of $@, to avoid missing mistakes such as
417 unintended C<eval> failures due to incorrect C<@INC>)
419 Specifically, this option prepends C<valgrind> C<--error-exitcode=124> to
420 the command line that runs the testcase, to cause valgrind to exit non-zero
421 if it detects errors, with the assumption that the test program itself
422 always exits with zero. If you require more flexibility than this, either
423 specify your C<valgrind> invocation explicitly as part of the test case, or
424 use a wrapper script to control the command line or massage the exit codes.
430 Test that the build completes, without running any test case.
432 By default, if the build for the desired I<target> fails to complete,
433 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
434 being that one wants to find a commit which changed state "builds && passes"
435 to "builds && fails". If instead one is interested in which commit broke the
436 build (possibly for particular F<Configure> options), use I<--test-build>
437 to treat a build failure as a failure, not a "skip".
439 Often this option isn't as useful as it first seems, because I<any> build
440 failure will be reported to C<git bisect> as a failure, not just the failure
441 that you're interested in. Generally, to debug a particular problem, it's
442 more useful to use a I<target> that builds properly at the point of interest,
443 and then a test case that runs C<make>. For example:
445 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
446 --expect-fail --force-manifest --target=miniperl make perl
448 will find the first revision capable of building L<DynaLoader> and then
449 F<perl>, without becoming confused by revisions where F<miniperl> won't
456 By default, a build will "skip" if any files listed in F<MANIFEST> are not
457 present. Usually this is useful, as it avoids false-failures. However, there
458 are some long ranges of commits where listed files are missing, which can
459 cause a bisect to abort because all that remain are skipped revisions.
461 In these cases, particularly if the test case uses F<miniperl> and no modules,
462 it may be more useful to force the build to continue, even if files
463 F<MANIFEST> are missing.
469 Run C<make regen_headers> before building F<miniperl>. This may fix a build
470 that otherwise would skip because the generated headers at that revision
471 are stale. It's not the default because it conceals this error in the true
472 state of such revisions.
478 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
484 F<bisect-runner.pl> will minimally patch various files on a platform and
485 version dependent basis to get the build to complete. Normally it defers
486 doing this as long as possible - C<.SH> files aren't patched until after
487 F<Configure> is run, and C<C> and C<XS> code isn't patched until after
488 F<miniperl> is built. If C<--all-fixups> is specified, all the fixups are
489 done before running C<Configure>. In rare cases adding this may cause a
490 bisect to abort, because an inapplicable patch or other fixup is attempted
491 for a revision which would usually have already I<skip>ed. If this happens,
492 please report it as a bug, giving the OS and problem revision.
502 Specify a file containing a patch or other fixup for the source code. The
503 action to take depends on the first line of the fixup file
511 If the first line starts C<#!perl> then the file is run using C<$^X>
517 If a shebang line is present the file is executed using C<system>
521 C<I<filename> =~ /I<pattern>/>
525 C<I<filename> !~ /I<pattern>/>
527 If I<filename> does not exist then the fixup file's contents are ignored.
528 Otherwise, for C<=~>, if it contains a line matching I<pattern>, then the
529 file is fed to C<patch -p1> on standard input. For C<=~>, the patch is
530 applied if no lines match the pattern.
532 As the empty pattern in Perl is a special case (it matches the most recent
533 sucessful match) which is not useful here, an the treatment of empty pattern
534 is special-cased. C<I<filename> =~ //> applies the patch if filename is
535 present. C<I<filename> !~ //> applies the patch if filename missing. This
536 makes it easy to unconditionally apply patches to files, and to use a patch
537 as a way of creating a new file.
541 Otherwise, the file is assumed to be a patch, and always applied.
545 I<early-fixup>s are applied before F<./Configure> is run. I<late-fixup>s are
546 applied just after F<./Configure> is run.
548 These options can be specified more than once. I<file> is actually expanded
549 as a glob pattern. Globs that do not match are errors, as are missing files.
555 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
556 to use F<bisect-runner.pl> to build the current particular perl revision for
557 interactive testing, or for debugging F<bisect-runner.pl>.
559 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
565 Test that all stable revisions can be built. By default, attempts to build
566 I<blead>, I<v5.14.0> .. I<perl-5.002> (or I<perl5.005> on a case insensitive
567 file system). Stops at the first failure, without
568 cleaning the checkout. Use I<--start> to specify the earliest revision to
569 test, I<--end> to specify the most recent. Useful for validating a new
570 OS/CPU/compiler combination. For example
572 ../perl/Porting/bisect.pl --validate -le 'print "Hello from $]"'
574 If no testcase is specified, the default is to use F<t/TEST> to run
581 Validate the options and arguments, and exit silently if they are valid.
587 Validate that the test case isn't an executable file with a
588 C<#!/usr/bin/perl> line (or similar). As F<bisect-runner.pl> does B<not>
589 automatically prepend C<./perl> to the test case, a I<#!> line specifying an
590 external F<perl> binary will cause the test case to always run with I<that>
591 F<perl>, not the F<perl> built by the bisect runner. Likely this is not what
592 you wanted. If your test case is actually a wrapper script to run other
593 commands, you should run it with an explicit interpreter, to be clear. For
594 example, instead of C<../perl/Porting/bisect.pl ~/test/testcase.pl> you'd
595 run C<../perl/Porting/bisect.pl /usr/bin/perl ~/test/testcase.pl>
