使用CVS獲取Mozilla源代碼

那些正在進行積極開發的人可以使用 CVS 查看最新的源代碼。如果您計劃提供補丁並修復錯誤，這是最好的方法，因為它可以讓您獲得最新的更新並將它們與您自己的更改合併。

如果要編譯產品以供發布，通常下載 Mozilla 源代碼 tarball

支持文檔

Anyone can check out (also known as "pull" or "download") the sources via CVS, but only certain people have the ability to check in (make changes, also known as "commit"). Those people are the module owners and their delegates. Read our document on hacking mozilla to find out how to get the ability to check in. You may also wish to read about Using SSH to connect to CVS.

Requirements

To check out the sources, you need to be running CVS 1.11 or later. 1.12.13 does not work with the CVS server, and instead results in hangs, although 1.12.9 is known to work. Furthermore, you must use GNU make to check out and build Mozilla. No other "make" program is acceptable. On windows, mac and regular GNU systems (like GNU/Linux), use "make" to run GNU make; on most non-GNU unixes (like e.g. Solaris, etc.), use "gmake".

CVS Client Settings

The "cvsroot" (repository identification string) used for anonymous access to Mozilla CVS is

:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot

If you are using a graphical CVS interface, use the following server data:

• host: "cvs-mirror.mozilla.org"
• repository path: "/cvsroot"
• user: "anonymous"
• connection type: pserver
• port: default (2401)

Selecting a Project to Pull

Since several different applications are built from the same basic source code, you must choose which application to checkout on the command line using the MOZ_CO_PROJECT variable. This information has to be supplied when it comes to the checkout of the actual source code (see the appropriate checkout section below, according to the branch you want to checkout). The possible options include the following:

browser 

The standalone "Firefox" browser.

mail 

The standalone "Thunderbird" mail/news client.

suite 

The traditional "Mozilla" SeaMonkey suite of browser, mail/news, composer, and other applications.

minimo 

The standalone browser for small devices.

composer 

The standalone HTML composer.

calendar 

The standalone "Sunbird" calendar app.

xulrunner 

The next-generation XUL application launcher.

camino 

The "Camino" native browser for Macintosh.

all 

Check out sources for all of the above projects, plus some additional utility code

Multiple projects can be specified with commas: MOZ_CO_PROJECT=suite,browser,xulrunner.

Note that if you are using a custom .mozconfig file, you can also specify MOZ_CO_PROJECT there, instead of including it on the command line.

Checking Out a New Source Tree

Check Tinderbox

Before pulling a tree, you should always check the appropriate Tinderbox to make sure that the codebase is not broken. If there are red tinderboxes, it is usually advisable to wait until they are green before pulling a tree.

Branch HEAD

To check out a new source tree from scratch, get the client.mk file which contains makefile instructions which are used to pull the rest of the tree:

$ cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co mozilla/client.mk

Note: if you have already set up a .mozconfig file, you may also need to check out the following files:

Firefox 

cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co mozilla/browser/config/mozconfig

Thunderbird 

cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co mozilla/mail/config/mozconfig

Specific Branch

If you want to check out the source code of a specific CVS branch, use

$ cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -r BRANCH mozilla/client.mk

instead. To, for example, pull the Firefox 2.0/Thunderbird 2.0/SeaMonkey 1.1 development branch, replace BRANCH above with MOZILLA_1_8_BRANCH. For available branch tags in Mozilla, see CVS Tags.

The information on pulling project specific .mozconfig files as listed in the previous section apply to other branches than HEAD as well of course.

Checkout

After having chosen the correct branch, run:

$ cd mozilla
$ make -f client.mk checkout MOZ_CO_PROJECT=option,option

As mentioned above, if you are using a custom .mozconfig file where you have already specified the MOZ_CO_PROJECT variable, you do not need to repeat it here on command line.

Specific Time

If you want to check out the source code as it was at a specific time you can use the MOZ_CO_DATE variable. For example MOZ_CO_DATE="20 Oct 2006 17:00 PDT".

This can either be added to your .mozconfig file, or specified on the command line, such as

$ cd mozilla
$ make -f client.mk checkout MOZ_CO_DATE="20 Oct 2006 17:00 PDT" MOZ_CO_PROJECT=option,option

Changing the Source Tree to a Different Branch

Branch HEAD

In order to update a source tree (be it branch HEAD or a specific branch) to latest branch HEAD, first run:

$ cd mozilla
$ cvs up -A client.mk

The -A option removes any "sticky branch" information, which leads to the effect that the tree is updated to HEAD.

Specific Branch

To update a source tree which was pulled from a specific branch, start with

$ cd mozilla
$ cvs up -r BRANCH client.mk

instead. Replace BRANCH by the tag of the branch you want to update.

Updating a Source Tree

To update your source tree simply do the following:

$ make -f client.mk checkout MOZ_CO_PROJECT=option,option

As always, if you use a custom .mozconfig file where MOZ_CO_PROJECT is already defined, you do not need to repeat it on command line.

Creating a Diff File

In order to create a diff of a single local file against the current file in the repository, use:

$ cvs diff -u8p FILENAME

See Creating a patch for more information.

Converting a Downloaded Source Tree

Downloaded source trees from mozilla.org (source tarballs) are already set up with CVS information, like a normal checkout. You can update these trees like normal trees to the latest code, without special action. See previous section on how to update a source tree.
