3 README.pod - README for the F<Porting/> directory in the Perl 5 core distribution.
7 =head2 F<acknowledgements.pl>
9 Generates the text which goes in the Acknowledgements section in
10 a perldelta. You pass in the previous version and it guesses the next
11 version, fetches information from the repository and outputs the
14 =head2 F<add-package.pl>
16 Program to prepare dual-life distributions for insertion into the Perl 5
17 F<lib/> and F<t/> directories. Now thought to be largely superseded.
19 =head2 F<bisect-example.sh>, F<bisect.pl> and F<bisect-runner.pl>
21 Use C<git bisect> to pinpoint changes.
23 =head2 F<bump-perl-version>
25 A utility to find, and optionally bump, references to the perl version
26 number in various files within the perl source.
30 Performs pathname portability checks, including whether there are naming
31 conflicts when names are truncated to the DOSish, case-ignoring 8.3 format.
33 =head2 F<checkansi.pl>
35 Check source code for ANSI-C violations.
37 =head2 F<checkAUTHORS.pl>
39 Used by F<t/porting/authors.t> to ensure the F<AUTHORS> list is up to date.
41 =head2 F<checkcfgvar.pl>
43 Check that the various F<config.sh>-clones have (at least) all the same
44 symbols as the top-level F<config_h.SH> so that the (potentially) needed
45 symbols are not lagging after how F<Configure> thinks the world is laid out.
46 VMS is probably not handled properly here, due to their own rather elaborate
49 =head2 F<check-cpan-pollution>
51 Scans the commit logs for commits that are potentially, illegitimately
52 touching modules that are primarily maintained outside of the perl core. Also
53 checks for commits that span multiple distributions in F<cpan/> or F<dist/>.
54 Makes sure that updated CPAN distributions also update
55 F<Porting/Maintainers.pl>, but otherwise ignores changes to that file (and
58 =head2 F<checkpodencoding.pl>
60 Check if POD files contain non-ASCII without specifying
61 encoding. Run it as: C<perl Porting/checkpodencoding.pl>.
65 Checks that all the URLs in the Perl source are valid.
67 =head2 F<checkVERSION.pl>
69 Used by F<t/porting/cmp_version.t> to ensure changed modules have had their
74 Command line tool to update cherrymaint; a tool for selecting commits from
75 blead to cherry-pick into stable perl versions.
77 =head2 F<cmpVERSION.pl>
79 Compare the current Perl source tree and a given tag for modules that have
80 identical version numbers but different contents.
84 This file is a sample F<config.h> file. If you are unable to successfully run
85 F<Configure>, copy this file to F<config.h> and edit it to suit your system.
89 Used when importing changes from F<metaconfig>. This script reorders
90 F<config_h.SH> after metaconfig.
94 This file is a sample F<config.sh> file. F<config.sh> is normally
95 produced by running the F<Configure> script. It holds all the definitions
96 figured out by F<Configure>. If you are unable to successfully run
97 F<Configure> on your system, copy this sample file to F<config.sh>
98 at the top of the perl source tree and edit it to suit your system.
99 Then propagate those values by running C<Configure -S>. This sample
100 file is normally updated each time F<Configure> is updated.
102 =head2 F<core-cpan-diff>
104 Compare CPAN modules with their equivalent in core.
105 Originally based on App::DualLivedDiff by Steffen Mueller.

115 modules included in the distribution.
117 =head2 F<corelist-perldelta.pl>

120 building. Also generates a diff between the corelist sections of two

156 from a series of git commits.

163 =head2 F<git-make-p4-refs>
165 This script creates a tag for every p4raw-id.
167 =head2 F<GitUtils.pm>
169 This script contains the subroutine to generate a F<.patch file> for a
170 committish (the SHA1 checksum of a commit, a number made of 40 hexadecimal
171 digits which acts the internal unique identifier for this commit
172 (lilypond.org). Related file: F<make_dot_patch.pl>
176 This file is built by F<metaconfig>. This file contains a description of all
177 the shell variables whose value is determined by the Configure script.
178 It later gets incorporated into the pod for F<Config.pm>.
180 =head2 F<how_to_write_a_perldelta.pod>
182 This file contains a specification as to how to write a perldelta pod.
183 Related file: F<perldelta_template.pod>
185 =head2 F<leakfinder.pl>
187 This script executes every line in every file in the build directory and its
188 subdirectories to determine if the number of SVs goes up and reports it as a
189 leak to STDOUT. WARNING! some harm could be done if a line contains something
190 similar to C<`rm *`>.
192 =head2 F<Maintainers>

225 =head2 F<make-rmg-checklist>
227 This script creates a release checklist as a simple HTML document.
229 =head2 F<make_snapshot.pl>
231 This script is a quick and dirty snapshot generator for the perl5.git.perl.org
232 web page to use to generate the snapshot files.
236 This script outputs a list of files in F<MANIFEST> which don't exist and a
237 list of files that exist and aren't in F<MANIFEST>.

262 distribution, provides functions useful during testing.
264 =head2 F<pod_rules.pl>

288 This file. An exhaustive list of the contents of the F<Porting/>
289 directory along with a description of each file.
290 The test F<t/porting/readme.t> ensures that this lists every file
291 and that every file is listed.
293 =head2 F<README.y2038>
295 The y2038 implementation for perl. This is an implementation of POSIX time.h
296 which solves the year 2038 bug on systems where time_t is only 32 bits. It is

298 L<http://y2038.googlecode.com/>.

302 Release announcement for minor releasements of the 5.19 development series.
304 =head2 F<release_managers_guide.pod>

307 so there may be new things not covered here, or tools may need updating.
309 =head2 F<release_schedule.pod>
311 This schedule lists the projected or historical development and release
312 schedules for the next, current and previous stable versions of Perl. Dates

318 Shell script to list patches in RT.
320 =head2 F<sort_perldiag.pl>

342 at L<http://perl5.git.perl.org/perl.git/blob_plain/HEAD:/Porting/todo.pod>.
343 The tasks we think are smaller or easier are listed first. Anyone is welcome
344 to work on any of these, but it's a good idea to first contact
345 I<perl5-porters@perl.org> to avoid duplication of effort, and to learn from
346 any previous attempts.
348 =head2 F<valgrindpp.pl>
350 A post-processor for C<make test.valgrind>. F<valgrindpp.pl> is a
351 post-processor for F<.valgrind> files created during C<make test.valgrind>. It
352 collects all these files, extracts most of the information and produces a
353 significantly shorter summary of all detected memory access errors and memory
