3 perlrepository - Using the Perl source repository
7 All of Perl's source code is kept centrally in a Git repository. The
8 repository contains many Perl revisions from Perl 1 onwards and all
9 the revisions from Perforce, the version control system we were using
10 previously. This repository is accessible in different ways.
12 The full repository takes up about 80MB of disk space. A check out of
13 blead takes up about 160MB of disk space (including the repository). A
14 build of blead takes up about 200MB (including the repository and the

19 =head2 READ ACCESS VIA THE WEB
21 You may access this over the web. This allows you to browse the tree,
22 see recent commits, search for particular commits and more. You may
25 http://perl5.git.perl.org/perl.git
27 =head2 READ ACCESS VIA GIT
29 You will need a copy of Git for your computer. You can fetch a copy of
30 the repository using the Git protocol (which uses port 9418):
32 git clone git://perl5.git.perl.org/perl.git perl-git
34 This clones the repository and makes a local copy in the 'perl-git'
37 If your local network does not allow you to use port 9418, then you can
38 fetch a copy of the repository over HTTP (this is slower):
40 git clone http://perl5.git.perl.org/perl.git perl-http
42 This clones the repository and makes a local copy in the 'perl-http'
45 =head2 WRITE ACCESS TO THE REPOSITORY
47 If you are a committer, then you can fetch a copy of the repository that
48 you can push back on with:
50 git clone ssh://perl5.git.perl.org/gitroot/perl.git perl-ssh
52 This clones the repository and makes a local copy in the 'perl-ssh'
55 If you clone using git, which is faster than ssh, then you will need to
56 modify your config in order to enable pushing. Edit .git/config where
57 you will see something like:
60 url = git://perl5.git.perl.org/perl.git
62 change that to something like this:
65 url = ssh://perl5.git.perl.org/gitroot/perl.git
67 NOTE: there are symlinks set up so that the /gitroot is actually optional.
69 =head1 OVERVIEW OF THE REPOSITORY
71 Once you have changed into the repository directory, you can inspect it.
73 The repository contains a few branches:
81 You can see recent commits:
85 And pull new changes from the repository:
89 To switch to another branch:
91 % git checkout origin/maint-5.8-dor
93 To switch back to blead:
97 =head1 SUBMITTING A PATCH
99 If you have a patch in mind for Perl, you should first get a copy of
102 % git clone git://perl5.git.perl.org/perl.git perl-git
104 Then change into the directory:
108 First we need to create a temporary new branch for these changes and
112 % git checkout orange
114 Then make your changes. For example, if Leon Brocard changes his name
115 to Orange Brocard, we should change his name in the AUTHORS file:
117 % perl -pi -e 's{Leon Brocard}{Orange Brocard}' AUTHORS
119 You can see what files are changed:
123 # Changes to be committed:
124 # (use "git reset HEAD <file>..." to unstage)
130 And you can see the changes:
133 diff --git a/AUTHORS b/AUTHORS
134 index 293dd70..722c93e 100644

148 Now commit your change locally:
151 % git commit -m 'Rename Leon Brocard to Orange Brocard'
152 Created commit 6196c1d: Rename Leon Brocard to Orange Brocard
153 1 files changed, 1 insertions(+), 1 deletions(-)
155 Now you should create a patch file for all your local changes:
157 % git-format-patch origin
158 0001-Rename-Leon-Brocard-to-Orange-Brocard.patch
160 You should now send an email to perl5-porters@perl.org with a
161 description of your changes, and attach this patch file as an
164 If you want to delete your temporary branch, you may do so with:
167 % git branch -d orange
168 error: The branch 'orange' is not an ancestor of your current HEAD.
169 If you are sure you want to delete it, run 'git branch -D orange'.
170 % git branch -D orange
171 Deleted branch orange.
