Recommended method for creating clone.bundle

[Matt Gumbel]

Hi all,

Is there a recommended way for creating clone.bundle files on a gerrit server?

I wonder if it is best to do it with a daily cron job or some other way. Any practical advice would be much appreciated!

thanks,

Run git bundle create. :-)

The only time we use them is about once every 6 months when a new
version of AOSP is made available. JBQ creates bundles with `git
bundle create` for the new version, uploads them to the CDN, and a new
Android is shipped.

We don't bother to make them automatically or periodically, the bitmap
based clone support works really well for normal daily traffic, and
the delta between the last release and the next release is usually
small enough to run on `git fetch`.

Thanks Shaun. One other question regarding bundles: where do I place the clone.bundle file so that the gerrit webserver will find it when a client asks for it? I tried placing it in the project's main .git directory as well as in the refs/ subdir but neither seemed to work.

Gerrit itself doesn't support serving clone.bundle files. You could
try using mod_rewrite in your Apache to trap URLs ending in
/clone.bundle and send them to a directory that Apache is configured
to serve files out of.

This is basically what we do for android.googlesource.com. Our web
server traps "^(.*)/clone.bundle" and rewrites $1 to a URL on the CDN
and sends the client a 302 redirect to follow to pick up the file off
the CDN.
