125=head1 DESCRIPTION
126
facd1b88 127Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use
77ae6092
NC
128of C<git bisect> as much as possible. With one command (and no other files)
129it's easy to find out

151usually without needing to know which versions of perl to use as start and
152end revisions.
153
facd1b88 154By default F<bisect.pl> will process all options, then use the rest of the
77ae6092
NC
155command line as arguments to list C<system> to run a test case. By default,
156the test case should pass (exit with 0) on earlier perls, and fail (exit
f7f0fdee
JL
157non-zero) on I<blead> (note that running most of perl's test files directly
158won't do this, you'll need to run them through a harness to get the proper
159error code). F<bisect.pl> will use F<bisect-runner.pl> to find the earliest
160stable perl version on which the test case passes, check that it fails on
161blead, and then use F<bisect-runner.pl> with C<git bisect run> to find the
162commit which caused the failure.
77ae6092
NC
163
164Because the test case is the complete argument to C<system>, it is easy to
165run something other than the F<perl> built, if necessary. If you need to run
166the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>
167
5842706e
NC
168You need a clean checkout to run a bisect, and you can't use the checkout
169which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
170a revision before F<Porting/bisect-runner.pl> was added, which
171C<git bisect run> needs). If your working checkout is called F<perl>, the
172simplest solution is to make a local clone, and run from that. I<i.e.>:
173
174 cd ..
175 git clone perl perl2
176 cd perl2
177 ../perl/Porting/bisect.pl ...
178
facd1b88 179By default, F<bisect-runner.pl> will automatically disable the build of
cfadff5f
NC
180L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical
181to patch DB_File 1.70 and earlier to build with current Berkeley DB headers.
182(ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.)
183If your F<db.h> is old enough you can override this with C<-Unoextensions>.

195search stable perl releases until it finds one where the test case passes.
196The default is to search from 5.002 to 5.14.0. If F<bisect.pl> detects that

244Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
245is simple XS module present since 5.000, this provides a fast test of
b4f0ec5f 246whether XS modules can be built. Note, XS modules are built by F<miniperl>,

260Build everything needed to run the tests. This is the default if we're

b4f0ec5f 262XS modules. For older F<Makefile>s, the previous name of C<test-prep>
77ae6092
NC
263is automatically substituted. For very old F<Makefile>s, C<make test> is
264run, as there is no target provided to just get things ready, and for 5.004

369
370Instead of running a test program to determine I<pass> or I<fail>,
371C<--match> will pass if the given regex matches, and hence search for the
372commit that removes the last matching file. C<--no-match> inverts the test,
373to search for the first commit that adds files that match.
bf8fb529
NC
374
375The remaining command line arguments are treated as glob patterns for files
376to match against. If none are specified, then they default as follows:
377
378=over 4
379
380=item *
77ae6092
NC
381
382If no I<target> is specified, the match is against all files in the
bf8fb529
NC
383repository (which is fast).
384
385=item *
386
387If a I<target> is specified, that target is built, and the match is against
388only the built files.
389
390=back
391
392Treating the command line arguments as glob patterns should not cause
393problems, as the perl distribution has never shipped or built files with
394names that contain characters which are globbing metacharacters.
395
396Anything which is not a readable file is ignored, instead of generating an
397error. (If you want an error, run C<grep> or C<ack> as a test case). This
398permits one to easily search in a file that changed its name. For example:
399
400 .../Porting/bisect.pl --match 'Pod.*Functions' 'pod/buildtoc*'
77ae6092 401
66b521dd

402C<--no-match ...> is implemented as C<--expect-fail --match ...>

77ae6092
NC
404=item *
405
406--test-build
407
408Test that the build completes, without running any test case.
409
410By default, if the build for the desired I<target> fails to complete,
411F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
412being that one wants to find a commit which changed state "builds && passes"
413to "builds && fails". If instead one is interested in which commit broke the
414build (possibly for particular F<Configure> options), use I<--test-build>
415to treat a build failure as a failure, not a "skip".
416
b4f0ec5f
NC
417Often this option isn't as useful as it first seems, because I<any> build
418failure will be reported to C<git bisect> as a failure, not just the failure
419that you're interested in. Generally, to debug a particular problem, it's
420more useful to use a I<target> that builds properly at the point of interest,
421and then a test case that runs C<make>. For example:
422
423 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
424 --expect-fail --force-manifest --target=miniperl make perl
425
facd1b88
NC
426will find the first revision capable of building L<DynaLoader> and then
427F<perl>, without becoming confused by revisions where F<miniperl> won't
b4f0ec5f
NC
428even link.

431
b4f0ec5f
NC
432--force-manifest
433
77ae6092
NC
434By default, a build will "skip" if any files listed in F<MANIFEST> are not
435present. Usually this is useful, as it avoids false-failures. However, there
436are some long ranges of commits where listed files are missing, which can
437cause a bisect to abort because all that remain are skipped revisions.
438
439In these cases, particularly if the test case uses F<miniperl> and no modules,
440it may be more useful to force the build to continue, even if files
441F<MANIFEST> are missing.

bfa52998
NC
445--force-regen
446
447Run C<make regen_headers> before building F<miniperl>. This may fix a build
448that otherwise would skip because the generated headers at that revision
449are stale. It's not the default because it conceals this error in the true
450state of such revisions.

459
460--no-clean
461
462Tell F<bisect-runner.pl> not to clean up after the build. This allows one
463to use F<bisect-runner.pl> to build the current particular perl revision for
464interactive testing, or for debugging F<bisect-runner.pl>.
465

NC
475cleaning the checkout. Use I<--start> to specify the earliest revision to

498not the F<perl> built by the bisect runner. Likely this is not what you
499wanted. If your test case is actually a wrapper script to run other
500commands, you should run it with an explicit interpreter, to be clear. For
501example, instead of C<../perl/Porting/bisect.pl ~/test/testcase.pl> you'd

2738 # Need to work around a bug in (at least) OpenBSD's 4.6's sparc64 #
2739 # compiler ["gcc (GCC) 3.3.5 (propolice)"]. Between commits
2740 # 3ec562b0bffb8b8b (2002) and 1a4fad37125bac3e^ (2005) the darling thing
2741 # fails to compile any code for the statement cc.oldcc = PL_regcc;
2742 #
2743 # If you refactor the code to "fix" that, or force the issue using set
2744 # in the debugger, the stack smashing detection code fires on return
2745 # from S_regmatch(). Turns out that the compiler doesn't allocate any
2746 # (or at least enough) space for cc.
2747 #
2748 # Restore the "uninitialised" value for cc before function exit, and the
2749 # stack smashing code is placated. "Fix" 3ec562b0bffb8b8b (which
2750 # changes the size of auto variables used elsewhere in S_regmatch), and
2751 # the crash is visible back to bc517b45fdfb539b (which also changes
2752 # buffer sizes). "Unfix" 1a4fad37125bac3e and the crash is visible until
2753 # 5b47454deb66294b. Problem goes away if you compile with -O, or hack
2754 # the code as below.
2755 #
2756 # Hence this turns out to be a bug in (old) gcc. Not a security bug we
2757 # still need to fix.
