RE: Why does a Git local clone need to be kept in sync?

2016-03-10 Thread Dunnigan, Terrence J 
For what it’s worth my group transitioned from GitWeb to cgit a couple of years 
ago. The performance increase was dramatic. I imagine there are other 
git-to-http options out there as well.

Subject: Re: Why does a Git local clone need to be kept in sync?

Review Board uses the repository to fetch the "original" version of the files 
for each change in order to construct the side-by-side view (since the diffs 
that are uploaded are just unified diffs with limited context).

Updating every 5 minutes is likely to work almost all the time, but if someone 
were to push a commit and then immediately post a review request for a change 
based on that commit, it might fail because it thinks the parent revision 
doesn't exist. For this reason many people choose to run something like GitWeb 
(or the new rb-gateway) on the same server as the canonical repository, which 
will never be out of sync. Unfortunately if Review Board is on a separate 
server from your git repository, it does require either the local clone or some 
API frontend because git's remote protocol does not allow fetching individual 
files.

My question is why? What features will break if the git repo is out of date?

I'm in the process of setting up ReviewBoard and I have a cron job that does a 
git pull on all the Git repos every 5 minutes. Is that sufficient or do I need 
to update on each commit?

Re: Why does a Git local clone need to be kept in sync?

2016-03-10 Thread David Trowbridge 
John,

rb-gateway has not had an official release, but there are a few people who
have built it and are running it. It's designed to be run on the same
server as your central git repository, so it doesn't use a clone at
all--it's therefore equivalent to how people use gitweb right now, but it
has a much simpler install and a smaller surface area.

Re: Why does a Git local clone need to be kept in sync?

2016-03-10 Thread John Borries 
Thanks for the quick reply David, that helps a lot.

Is rb-gateway released yet? I can't find a lot of info about it yet. Will 
it handle this problem of keeping the git repo's up to date? I could 
imagine if there is a service between ReviewBoard and the Git repo, when rb 
asks rb-gateway for a file for a diff, rb-gateway could first fetch the 
latest file from the central git server.

Re: Why does a Git local clone need to be kept in sync?

Review Board uses the repository to fetch the "original" version of the
files for each change in order to construct the side-by-side view (since
the diffs that are uploaded are just unified diffs with limited context).

Updating every 5 minutes is likely to work almost all the time, but if
someone were to push a commit and then immediately post a review request
for a change based on that commit, it might fail because it thinks the
parent revision doesn't exist. For this reason many people choose to run

Review Board is on a separate server from your git repository, it does
require either the local clone or some API frontend because git's remote
