If you have a poor network connection that is preventing
hg clone from completing, you may want to try downloading a bundle of the repository you’re interested in. This is useful since a file download, unlike
hg clone, can be resumed if the connection is interrupted. Once you have the bundle, staying up-to-date shouldn’t take much time at all, if you keep up with it regularly.
This document explains the steps to setup the mozilla-unified repository using a bundle file. Be sure to replace “
mozilla-unified” with the project you’re working with as appropriate.
Download the bundle¶
Open https://hg.cdn.mozilla.net/ :
It lists up-to-date bundles for some of the repositories listed at https://hg.mozilla.net/ . Each row corresponds to each repository, and each column corresponds to each compression format.
Download the bundle file for the
Click the link in the “mozilla-unified” row, the “zstd (max)” column.
Setting up the repository¶
Once you have downloaded the repository bundle, follow the steps below to recreate the repository locally based upon that bundle.
Initialize a new repository (in a directory called
mkdir mozilla-unified hg init mozilla-unified
Un-bundle the bundle file to that repository:
Move the bundle file next to
mozilla-unified directory, and rename it to
cd mozilla-unified hg unbundle ../bundle.hg
Get comfortable. Grab a coffee (or your favorite tasty beverage). Maybe a nap. This unbundling process is going to take quite a lot of time.
Create the repository’s config file
.hg/hgrc, and add the following lines, so that Mercurial will automatically know where to pull changes from future updates. You can open the template config file in your editor by running
hg config --local --editor
EDITOR=<editor-of-your-choice> hg config --local --edit
[paths] default = https://hg.mozilla.org/mozilla-unified/
Update the repository to get all the changes since the bundle was created (this step also doubles as a check of the bundle integrity since if its contents are not exactly the same as what’s in the official repository then the
hg pullwill fail):
Check out a working copy from your new up to date repository:
You now have a clone of
mozilla-unified that is identical to one made via
hg clone. You can adjust your build settings, or you can go straight ahead and build Firefox!
