115 Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use
116 of C<git bisect> as much as possible. With one command (and no other files)
117 it's easy to find out
123 Which commit caused this example code to break?
127 Which commit caused this example code to start working?
131 Which commit added the first file to match this regex?
135 Which commit removed the last file to match this regex?
139 usually without needing to know which versions of perl to use as start and
142 By default F<bisect.pl> will process all options, then use the rest of the
143 command line as arguments to list C<system> to run a test case. By default,
144 the test case should pass (exit with 0) on earlier perls, and fail (exit
145 non-zero) on I<blead> (note that running most of perl's test files directly
146 won't do this, you'll need to run them through a harness to get the proper
147 error code). F<bisect.pl> will use F<bisect-runner.pl> to find the earliest
148 stable perl version on which the test case passes, check that it fails on
149 blead, and then use F<bisect-runner.pl> with C<git bisect run> to find the
150 commit which caused the failure.
152 Because the test case is the complete argument to C<system>, it is easy to
153 run something other than the F<perl> built, if necessary. If you need to run
154 the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>
156 You need a clean checkout to run a bisect, and you can't use the checkout
157 which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
158 a revision before F<Porting/bisect-runner.pl> was added, which
159 C<git bisect run> needs). If your working checkout is called F<perl>, the
160 simplest solution is to make a local clone, and run from that. I<i.e.>:
165 ../perl/Porting/bisect.pl ...
167 By default, F<bisect-runner.pl> will automatically disable the build of
168 L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical
169 to patch DB_File 1.70 and earlier to build with current Berkeley DB headers.
170 (ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.)
171 If your F<db.h> is old enough you can override this with C<-Unoextensions>.
179 --start I<commit-ish>
181 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
182 else C<git> understands as a revision). If not specified, F<bisect.pl> will
183 search stable perl releases until it finds one where the test case passes.
184 The default is to search from 5.002 to 5.14.0. If F<bisect.pl> detects that
185 the checkout is on a case insensitive file system, it will search from
192 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
199 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
200 this should be one of
208 Just run F<./Configure>
214 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
226 Use F<miniperl> to build F<lib/Config.pm>
232 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
233 is simple XS module present since 5.000, this provides a fast test of
234 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
235 hence this target will not build F<perl>.
241 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
242 F<ext>. XS modules (such as L<Fcntl>) are not built.
248 Build everything needed to run the tests. This is the default if we're
249 running test code, but is time consuming, as it means building all
250 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
251 is automatically substituted. For very old F<Makefile>s, C<make test> is
252 run, as there is no target provided to just get things ready, and for 5.004
253 and earlier the tests run very quickly.
259 --one-liner 'code to run'
265 Example code to run, just like you'd use with C<perl -e>.
267 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
268 or F<./miniperl> if I<target> is C<miniperl>.
270 (Usually you'll use C<-e> instead of providing a test case in the
271 non-option arguments to F<bisect.pl>)
273 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
274 which interferes with detecting errors in the example code itself.
280 Add C<-c> to the command line, to cause perl to exit after syntax checking.
286 Add C<-l> to the command line with C<-e>
288 This will automatically append a newline to every output line of your testcase.
289 Note that you can't specify an argument to F<perl>'s C<-l> with this, as it's
290 not feasible to emulate F<perl>'s somewhat quirky switch parsing with
291 L<Getopt::Long>. If you need the full flexibility of C<-l>, you need to write
292 a full test case, instead of using C<bisect.pl>'s C<-e> shortcut.
298 Add C<-w> to the command line with C<-e>
300 It's not valid to pass C<-c>, C<-l> or C<-w> to C<bisect.pl> unless you are
307 The test case should fail for the I<start> revision, and pass for the I<end>
308 revision. The bisect run will find the first commit where it passes.
312 -D I<config_arg=value>
320 -A I<config_arg=value>
322 Arguments (C<-A>, C<-D>, C<-U>) to pass to F<Configure>. For example,
324 -Dnoextensions=Encode
326 -Accflags=-DNO_MATHOMS
328 Repeated C<-A> arguments are passed
329 through as is. C<-D> and C<-U> are processed in order, and override
330 previous settings for the same parameter. F<bisect-runner.pl> emulates
331 C<-Dnoextensions> when F<Configure> itself does not provide it, as it's
332 often very useful to be able to disable some XS extensions.
338 The C<make> command to use. If this not set, F<make> is used. If this is
339 set, it also adds a C<-Dmake=...> else some recursive make invocations
340 in extensions may fail. Typically one would use this as C<--make gmake>
341 to use F<gmake> in place of the system F<make>.
351 Number of C<make> jobs to run in parallel. A value of 0 suppresses
352 parallelism. If F</proc/cpuinfo> exists and can be parsed, or F</sbin/sysctl>
353 exists and reports C<hw.ncpu>, or F</usr/bin/getconf> exists and reports
354 C<_NPROCESSORS_ONLN> defaults to 1 + I<number of CPUs>. On HP-UX with the
355 system make defaults to 0, otherwise defaults to 2.
365 Instead of running a test program to determine I<pass> or I<fail>,
366 C<--match> will pass if the given regex matches, and hence search for the
367 commit that removes the last matching file. C<--no-match> inverts the test,
368 to search for the first commit that adds files that match.
370 The remaining command line arguments are treated as glob patterns for files
371 to match against. If none are specified, then they default as follows:
377 If no I<target> is specified, the match is against all files in the
378 repository (which is fast).
382 If a I<target> is specified, that target is built, and the match is against
383 only the built files.
387 Treating the command line arguments as glob patterns should not cause
388 problems, as the perl distribution has never shipped or built files with
389 names that contain characters which are globbing metacharacters.
391 Anything which is not a readable file is ignored, instead of generating an
392 error. (If you want an error, run C<grep> or C<ack> as a test case). This
393 permits one to easily search in a file that changed its name. For example:
395 .../Porting/bisect.pl --match 'Pod.*Functions' 'pod/buildtoc*'
397 C<--no-match ...> is implemented as C<--expect-fail --match ...>
403 Test that the build completes, without running any test case.
405 By default, if the build for the desired I<target> fails to complete,
406 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
407 being that one wants to find a commit which changed state "builds && passes"
408 to "builds && fails". If instead one is interested in which commit broke the
409 build (possibly for particular F<Configure> options), use I<--test-build>
410 to treat a build failure as a failure, not a "skip".
412 Often this option isn't as useful as it first seems, because I<any> build
413 failure will be reported to C<git bisect> as a failure, not just the failure
414 that you're interested in. Generally, to debug a particular problem, it's
415 more useful to use a I<target> that builds properly at the point of interest,
416 and then a test case that runs C<make>. For example:
418 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
419 --expect-fail --force-manifest --target=miniperl make perl
421 will find the first revision capable of building L<DynaLoader> and then
422 F<perl>, without becoming confused by revisions where F<miniperl> won't
429 By default, a build will "skip" if any files listed in F<MANIFEST> are not
430 present. Usually this is useful, as it avoids false-failures. However, there
431 are some long ranges of commits where listed files are missing, which can
432 cause a bisect to abort because all that remain are skipped revisions.
434 In these cases, particularly if the test case uses F<miniperl> and no modules,
435 it may be more useful to force the build to continue, even if files
436 F<MANIFEST> are missing.
442 Run C<make regen_headers> before building F<miniperl>. This may fix a build
443 that otherwise would skip because the generated headers at that revision
444 are stale. It's not the default because it conceals this error in the true
445 state of such revisions.
451 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
457 F<bisect-runner.pl> will minimally patch various files on a platform and
458 version dependent basis to get the build to complete. Normally it defers
459 doing this as long as possible - C<.SH> files aren't patched until after
460 F<Configure> is run, and C<C> and C<XS> code isn't patched until after
461 F<miniperl> is built. If C<--all-fixups> is specified, all the fixups are
462 done before running C<Configure>. In rare cases adding this may cause a
463 bisect to abort, because an inapplicable patch or other fixup is attempted
464 for a revision which would usually have already I<skip>ed. If this happens,
465 please report it as a bug, giving the OS and problem revision.
471 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
472 to use F<bisect-runner.pl> to build the current particular perl revision for
473 interactive testing, or for debugging F<bisect-runner.pl>.
475 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
481 Test that all stable revisions can be built. By default, attempts to build
482 I<blead>, I<v5.14.0> .. I<perl-5.002> (or I<perl5.005> on a case insensitive
483 file system). Stops at the first failure, without
484 cleaning the checkout. Use I<--start> to specify the earliest revision to
485 test, I<--end> to specify the most recent. Useful for validating a new
486 OS/CPU/compiler combination. For example
488 ../perl/Porting/bisect.pl --validate -le 'print "Hello from $]"'
490 If no testcase is specified, the default is to use F<t/TEST> to run
497 Validate the options and arguments, and exit silently if they are valid.
503 Validate that the test case isn't an executable file with a
504 C<#!/usr/bin/perl> line (or similar). As F<bisect-runner.pl> does B<not>
505 prepend C<./perl> to the test case, a I<#!> line specifying an external
506 F<perl> binary will cause the test case to always run with I<that> F<perl>,
507 not the F<perl> built by the bisect runner. Likely this is not what you
508 wanted. If your test case is actually a wrapper script to run other
509 commands, you should run it with an explicit interpreter, to be clear. For
510 example, instead of C<../perl/Porting/bisect.pl ~/test/testcase.pl> you'd
511 run C<../perl/Porting/bisect.pl /usr/bin/perl ~/test/testcase.pl>
