Mercurial is a source code management tool which enables users to track changes to their source code locally and share their changes with others. The Mozilla project is in transition from using CVS for Mozilla 1.9 development to Mercurial for Mozilla 1.9.1 development and onwards.
The settings are the same as for the core Firefox 3.5/xulrunner 1.9.1 development. See Mozilla_Source_Code_(Mercurial)#Client_settings.
http://hg.mozilla.org/comm-central/(trunk builds of Thunderbird, SeaMonkey, and Sunbird)
http://hg.mozilla.org/releases/mozilla-1.9.1/(Thunderbird 3.0, SeaMonkey 2.0, Sunbird 1.0)
For more information on these branches, see the comm-central page.
The Thunderbird, SeaMonkey, Lightning and Sunbird source code is contained in several different repositories. The main integration repository for those applications is comm-central, which contains the main code that is required in addition to the core Gecko code. It also contains a script,
client.py, which is used to get the other code.
To get one of the comm-central repositories, clone it (using Mercurial terminology). Do the following, replacing
<location of repository> with one of the URLs from the Branches section above, depending upon what you want to build:
# Pull the Mozilla source to the folder src/ - may take a while # as hundreds of megabytes of history is downloaded to .hg hg clone <location of repository> src cd src
Update/pull all other needed sources using
python client.py checkout
Note: If you get the error message "No module named subprocess", install Python 2.4 or later.
This step downloads hundreds of megabytes of data. It can take a while, depending on your network connection.
client.py performs the following tasks:
- Pulls any new changesets to the comm-central codebase
- Pulls the mozilla-central codebase into mozilla/
- Pulls the following repositories into mozilla/extensions/:
- irc (Chatzilla)
- inspector (DOM Inspector)
- Pulls the LDAP SDK codebase into ldap/sdks/ (Except on recent trunk — December 2010 — this is done by CVS and the destination is mozilla/directory/c-sdk instead)
hg updateafter each
hg pullabove to update the corresponding repository clone's working directory contents. This is not required (in fact, you may prefer to pull manually). Pass
client.pyto skip this.
Updating the repository
To update the repository, just run
python client.py checkout
Using Mercurial bundles
To only obtain the latest version of the source tree, you can use the Github comm-central mirror (called gecko-dev) as follows. For quick tests, this is appropriate it is because faster than the complete clone.
# does not store the zip file on disk, uncompress on the fly bsdtar -x -f <(curl -s -L https://github.com/mozilla/releases-comm-central/archive/master.zip) cd gecko-dev-master
For the comm-central apps, see the following links:
The following script runs the checkout, build, and package operations in turn, telling you what it does (and when) and stopping at (and displaying) the first nonzero program exit code. It is written for the
bash shell on Linux-i686 and for an object directory set with
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-@CONFIG_GUESS@, but it can be easily adapted for other Mozilla building environments:
#!/bin/bash # set the following to the actual location of your objdir # if you want to package an installable archive export MY_OBJDIR=obj-i686-pc-linux-gnu date && \ echo 'python client.py checkout' && \ python client.py checkout && \ date && \ echo 'make -f client.mk build' && \ make -f client.mk build && \ test -n "$MY_OBJDIR" -a -d $MY_OBJDIR && \ date && \ echo "make -C $MY_OBJDIR package" && \ make -C $MY_OBJDIR package echo 'Exit status' $? date
Firefox and xulrunner
You can, if needed, build Firefox or
xulrunner from this tree. As
client.py pulls the mozilla-central repository, builds and development of Firefox and
xulrunner can take place within a repository from comm-central. The only difference is that you must be in the mozilla/ directory before running the build command:
cd src/mozilla make -f client.mk build
