You can repeat the 'config' line as many times as you like, and the last
|
||||||
|
occurrence will be the one in effect. This allows you to override settings
|
||||||
|
just for one project, as in this example:
|
||||||
|
|
||||||
|
repo @all
|
||||||
|
config gitolite.mirror.master = "frodo"
|
||||||
|
config gitolite.mirror.slaves = "sam gollum"
|
||||||
|
|
||||||
|
repo top-secret-project
|
||||||
|
# only sam, because we don't trust gollum
|
||||||
|
config gitolite.mirror.slaves = "sam"
|
||||||
|
|
||||||
|
The "delete config variable" syntax can also be used, if you wish:
|
||||||
|
|
||||||
|
repo highlander # there can be only one!
|
||||||
|
config gitolite.mirror.master =
|
||||||
|
config gitolite.mirror.slaves =
|
||||||
|
|
||||||
|
As you can see, the general idea is to place the most generic ones (`repo
|
||||||
|
@all`, or repo patterns like `repo foo.*`) first, and place more specific ones
|
||||||
|
later to override the generic settings.

# mirroring gitolite servers

Mirroring git repos is essentially a one-liner. For each mirror you want to
|
Mirroring a repo is simple in git; you just need code like this in a
|
||||||
update, you just add a post-receive hook that says
|
`post-receive` hook in each repo:
|
||||||
|
|
||||||
#!/bin/bash

#!/bin/bash
|

git push --mirror slave_user@mirror.host:/path/to/repo.git

git push --mirror slave_user@mirror.host:/path/to/repo.git
|
||||||
|
# if running gitolite, the $GL_REPO variable could be useful:
|
||||||
|
# git push --mirror slave_user@mirror.host:/repo/base/path/$GL_REPO.git
|
||||||
|
|
||||||
But life is never that simple...
|
For a lot of people, though, mirroring is more than just 'backup', and their
|
||||||
|
needs are complex enough that setup is hard.

**Update 2011-03-10**: I wrote this with a typical "corporate" setup in mind
|
|
||||||
where all the servers involved are owned and administered by the same group of
|
|
||||||
people. As a result, the scripts assume the servers trust each other
|
|
||||||
completely. If that is not your situation, you will have to add code into
|
|
||||||
`gl-mirror-shell` to limit the commands the remote may send. Patches welcome

### why
|
||||||
|
|
||||||
|
This document is useful if:
|
||||||
|
|
||||||
|
* you have multiple repositories spread across multiple sites around the
|
||||||
|
country/world, and would like developers to access their local server
|
||||||
|
instead of hitting the WAN, at least for 'fetch' operations.
|
||||||
|
|
||||||
|
* you don't want all your repos mirrored to all the servers for various
|
||||||
|
reasons, technical or otherwise (epecially true when some of the mirrors
|
||||||
|
don't belong to you).
|
||||||
|
|
||||||
|
* you want some mirrors to be updated only at certain times of the day,
|
||||||
|
(with a simple command), instead of every time a push happens.
|
||||||
|
|
||||||
|
* you don't want *one* server being the master server for *all* repos;
|
||||||
|
instead you want to choose where a repo gets "mastered" based on where the
|
||||||
|
majority of that repo's users are.
|
||||||
|
|
||||||
|
* you might even, if your servers are all in your control, want the
|
||||||
|
convenience of them *pushing to a mirror*, and having the push redirect
|
||||||
|
transparently to the master server.
|
||||||
|
|
||||||
|
As you can see, this is a bit more than a backup solution ;-)

#### server level setup
|
||||||
|
|
||||||
XXX review this document after testing mirroring...
|
To start with, assign each server a short name. We will use 'frodo', 'sam',
|
||||||
|
and 'gollum' as examples here.
|
||||||
|
|
||||||
If you installed gitolite using the from client method, run the following:
|
1. Generate ssh keys on each machine. Copy the `.pub` files to all other
|
||||||
|
machines with the appropriate names. I.e., frodo should have sam.pub and
|
||||||
|
gollum.pub, etc.
|
||||||
|
|
||||||
# on foo
|
2. Install gitolite on all servers, under some 'hosting user' (we'll use
|
||||||
export GL_BINDIR=$HOME/.gitolite/src
|
`git` in our examples here). You need not use the same hosting user on
|
||||||
cat bar.pub baz.pub |
|
all machines.
|
||||||
sed -e 's,^,command="'$GL_BINDIR'/gl-mirror-shell" ,' >> ~/.ssh/authorized_keys
|
|
||||||
|
|
||||||
If you installed using any of the other 3 methods do this:
|
It is not necessary to use the same "admin key" on all the machines.
|
||||||
|
However, if you do plan to mirror the gitolite-admin repo also, they will
|
||||||
|
eventually become the same anyway. In our example, frodo does mirror the
|
||||||
|
admin repo to sam, but not to gollum. (Can you really see frodo or sam
|
||||||
|
trusting gollum?)
|
||||||
|
|
||||||
# on foo
|
3. Now copy `hooks/common/post-receive.mirrorpush` from the gitolite source,
|
||||||
export GL_BINDIR=`gl-query-rc GL_BINDIR`
|
and install it as a custom hook called `post-receive`; see [here][ch] for
|
||||||
cat bar.pub baz.pub |
|
instructions.
|
||||||
sed -e 's,^,command="'$GL_BINDIR'/gl-mirror-shell" ,' >> ~/.ssh/authorized_keys
|
|
||||||
|
|
||||||
Also do the same thing on the other machines.
|
4. Edit `~/.gitolite.rc` on each machine and add/edit the following lines.
|
||||||
|
The `GL_HOSTNAME` variable **must** have the correct name for that host
|
||||||
|
(frodo, sam, or gollum), so that will definitely be different on each
|
||||||
|
server. The other line can be the same, or may have additional patterns
|
||||||
|
for other `git config` keys you have previously enabled. See [here][rsgc]
|
||||||
|
and the description for `GL_GITCONFIG_KEYS` in [this][vsi] for details.
|
||||||
|
|
||||||
Now test this access:
|
$GL_HOSTNAME = 'frodo'; # will be different on each server!
|
||||||
|
$GL_GITCONFIG_KEYS = "gitolite.mirror.*";
|
||||||
|
|
||||||
# on foo
|
(Remember the "rc" file is NOT mirrored; it is meant to be site-local).
|
||||||
ssh gitolite@bar pwd
|
|
||||||
# should print /home/gitolite/repositories
|
|
||||||
ssh gitolite@bar uname -a
|
|
||||||
# should print the appropriate info for that server
|
|
||||||
|
|
||||||
Similarly test the other combinations.
|
Note: if `GL_HOSTNAME` is undefined, you cannot push to repos which have
|
||||||
|
the 'gitolite.mirror.master' config variable set. (See 'details' section
|
||||||
|
below for more info on this variable).
|
||||||
|
|
||||||
<a name="_set_slaves_to_slave_mode"></a>
|
5. On each machine, add the keys for all other machines. For example, on
|
||||||
|
frodo you'd run these two commands:
|
||||||
|
|
||||||
#### set slaves to slave mode
|
gl-tool add-mirroring-peer sam.pub
|
||||||
|
gl-tool add-mirroring-peer gollum.pub
|
||||||
|
|
||||||
Set slave mode on all the *slave* servers by setting `$GL_SLAVE_MODE = 1`
|
6. Create "host" aliases on each machine to refer to all other machines. See
|
||||||
(uncommenting the line if necessary).
|
[here][ha] for what/why/how.
|
||||||
|
|
||||||
Leave the master server's file as is.
|
The host alias for a host (in other machines' `~/.ssh/config` files) MUST
|
||||||
|
be the same as the `GL_HOSTNAME` in the referred host's `~/.gitolite.rc`.
|
||||||
|
Gitolite mirroring **requires** this consistency in naming; things will
|
||||||
|
NOT work otherwise.
|
||||||
|
|
||||||
<a name="_set_slave_server_lists"></a>
|
For example, if machine A's `~/.gitolite.rc` says `$GL_HOSTNAME =
|
||||||
|
'frodo';`, then all other machines must use a host alias of "frodo" in
|
||||||
|
their `~/.ssh/config` files to refer to machine A.
|
||||||
|
|
||||||
#### set slave server lists
|
Once you've done this, each host should be able to reach the other hosts and
|
||||||
|
get a response back. For example, running this on sam:
|
||||||
|
|
||||||
On the master (foo), set the names of the slaves by editing the
|
ssh frodo info
|
||||||
`~/.gitolite.rc` to contain:
|
|
||||||
|
|
||||||
$ENV{GL_SLAVES} = 'gitolite@bar gitolite@baz';
|
should get you
|
||||||
|
|
||||||
**Note the syntax well; this is critical**:
|
Hello sam, I am frodo.
|
||||||
|
|
||||||
* **this must be in single quotes** (or you must remember to escape the `@`)
|
Check this command from *everywhere to everywhere else*, and make sure you get
|
||||||
* the variable is an ENV var, not a plain perl var
|
expected results. **Do NOT proceed otherwise.**
|
||||||
* the values are *space separated*
|
|
||||||
* each value represents the userid and hostname for one server
|
|
||||||
|
|
||||||
The basic idea is that this string, should be usable in both the following
|
<a name="_repository_level_setup"></a>
|
||||||
syntaxes:
|
|
||||||
|
|
||||||
git clone gitolite@bar:repo
|
#### repository level setup
|
||||||
ssh gitolite@bar pwd
|
|
||||||
|
|
||||||
You can also use ssh host aliases. Let's say server "bar" has a non-standard
|
Setting up mirroring at the repository level instead of at the "entire server"
|
||||||
port number:
|
level gives you a lot of flexibility (see "discussion" section below).
|
||||||
|
|
||||||
# in ~/.ssh/config on foo
|
The basic idea is to use `git config` variables within each repo (gitolite
|
||||||
host mybar
|
allows you to create them from within the gitolite.conf file so that's
|
||||||
hostname bar
|
convenient), and use these to specify which machine is the master and which
|
||||||
user gitolite
|
machines are slaves for the repo.
|
||||||
port 2222
|
|
||||||
|
|
||||||
# in ~/.gitolite.rc on foo
|
<font color="gray">
|
||||||
$ENV{GL_SLAVES} = 'bar gitolite@baz';
|
|
||||||
|
|
||||||
And that's really all there is, unless...

Let's say frodo and sam are internal servers, while gollum is an external (and
|
||||||
|
therefore less trusted) server that has agreed to help us out by mirroring one
|
||||||
|
of our high traffic repos. We want the following setup:
|
||||||
|
|
||||||
|
* the "gitolite-admin" repo, as well as an internal project repo called
|
||||||
|
"ip1", should be mastered on frodo and mirrored to sam.
|
||||||
|
|
||||||
|
* internal project "ip2" has almost all of its developers closer to sam, so
|
||||||
|
it should be mastered there, and mirrored on frodo.
|
||||||
|
|
||||||
|
* an open source project we manage, "os1", should be mastered on frodo and
|
||||||
|
mirrored on both sam and gollum.
|
||||||
|
|
||||||
|
So here's how our example would go:
|
||||||
|
|
||||||
|
1. Clone frodo's and sam's gitolite-admin repos to your workstation, then add
|
||||||
|
the following lines to both their gitolite.conf files:
|
||||||
|
|
||||||
|
repo ip1 gitolite-admin
|
||||||
|
config gitolite.mirror.master = "frodo"
|
||||||
|
config gitolite.mirror.slaves = "sam"
|
||||||
|
|
||||||
|
repo ip2
|
||||||
|
config gitolite.mirror.master = "sam"
|
||||||
|
config gitolite.mirror.slaves = "frodo"
|
||||||
|
|
||||||
|
You also need normal access control lines for ip1 and ip2; I'm assuming
|
||||||
|
you already have them elsewhere, at least on frodo. (What you have on sam
|
||||||
|
won't matter in a few minutes, as you will see!)
|
||||||
|
|
||||||
|
Commit and push these changes.
|
||||||
|
|
||||||
|
2. There are a couple of quirks to keep in mind when you make changes to the
|
||||||
|
gitolite-admin repo's config.
|
||||||
|
|
||||||
|
* the first push will create the `git config` entries required, but by
|
||||||
|
then it is too late to *act* on them; i.e., actually do the mirroring.
|
||||||
|
If there were any older values, like a different list of slaves
|
||||||
|
perhaps, then those would be in effect.
|
||||||
|
|
||||||
|
This is largely because git invokes post-receive before post-update.
|
||||||
|
In theory I can work around this but I do not intend to.
|
||||||
|
|
||||||
|
Anyway, this means that after the 2 pushes, you have to make a dummy
|
||||||
|
push from frodo:
|
||||||
|
|
||||||
|
git commit --allow-empty -m empty; git push
|
||||||
|
|
||||||
|
which gets you something like this amidst the other messages:
|
||||||
|
|
||||||
|
remote: (25158&) frodo ==== (gitolite-admin) ===> sam
|
||||||
|
|
||||||
|
telling you that frodo is sending gitolite-admin to sam in the
|
||||||
|
background.
|
||||||
|
|
||||||
|
* the second quirk is that your clone of server sam's gitolite-admin
|
||||||
|
repo is now completely out of date, since frodo has overwritten it on
|
||||||
|
the server. You have to 'cd' to that clone and do this:
|
||||||
|
|
||||||
|
git fetch
|
||||||
|
git reset --hard origin/master
|
||||||
|
|
||||||
|
2. That completes the setup of the gitolite-admin and the internal project
|
||||||
|
repos. We'll now setup things for the open source project, "os1".
|
||||||
|
|
||||||
|
On frodo's gitolite-admin clone, add the following lines to
|
||||||
|
`conf/gitolite.conf`, then commit and push:
|
||||||
|
|
||||||
|
repo os1
|
||||||
|
config gitolite.mirror.master = "frodo"
|
||||||
|
config gitolite.mirror.slaves = "sam gollum"
|
||||||
|
|
||||||
|
Also, send the same lines to gollum's administrator and ask him to add
|
||||||
|
them into his conf/gitolite.conf file, commit, and push.

|
||||||
|
|
||||||
|
#### commands to (re-)sync mirrors
|
||||||
|
|
||||||
|
You don't have to put all the slaves in `gitolite.mirror.slaves`. For
|
||||||
|
example, let's say you have some repos that are very active, and two of your
|
||||||
|
mirrors that are halfway across the world are getting pushed very frequently.
|
||||||
|
But you don't need those mirrors to be that closely updated, perhaps *because*
|
||||||
|
they are halfway across the world and those guys are asleep ;-)
|
||||||
|
|
||||||
|
Or maybe there was a network glitch and even the default slaves are now
|
||||||
|
lagging, so they need to be manually synced.
|
||||||
|
|
||||||
|
Or a slave realised that one of its repos is lagging for some reason, and
|
||||||
|
wants to request an immediate update.
|
||||||
|
|
||||||
|
Whatever the reason, you need ways to sync a repo from a command line. Here
|
||||||
|
are ways to do that:
|
||||||
|
|
||||||
|
1. On the master server, you can start a **background** job to mirror a repo.
|
||||||
|
The command/syntax is
|
||||||
|
|
||||||
|
gl-mirror-shell request-push reponame [list of keys/slaves]
|
||||||
|
|
||||||
|
The list at the end is optional, and can be a mix of slave names or your
|
||||||
|
own gitolite mirror config keys. (Yes, you can have any key, named
|
||||||
|
anything you like, as long as it starts with `gitolite.mirror.`).
|
||||||
|
|
||||||
|
If the list is not supplied, the `gitolite.mirror.slaves` key is used.
|
||||||
|
|
||||||
|
Keys can have values that in turn contain a list of keys/slaves. The list
|
||||||
|
is recursively *expanded* but recursion is not *detected*. Order is
|
||||||
|
preserved while duplicates are removed. If you didn't get that, see the
|
||||||
|
example :-)
|
||||||
|
|
||||||
|
**Warning**: the `gitolite.mirror.slaves` key should have only hosts, no
|
||||||
|
keys, in it.
|
||||||
|
|
||||||
|
The program exits with a return value of "1" if it found no slaves in the
|
||||||
|
list passed, otherwise it fires off the background job, prints an
|
||||||
|
informative message, and exits with a return value of "0".
|
||||||
|
|
||||||
|
We'll take an example. Let's say your gitolite config file has this:
|
||||||
|
|
||||||
|
repo ip1
|
||||||
|
config gitolite.mirror.master = "frodo"
|
||||||
|
config gitolite.mirror.slaves = "sam merry pippin"
|
||||||
|
config gitolite.mirror.hourly = "sam legolas"
|
||||||
|
config gitolite.mirror.nightly = "gitolite.mirror.hourly gimli"
|
||||||
|
config gitolite.mirror.all = "gitolite.mirror.nightly gitolite.mirror.hourly gitolite.mirror.slaves"
|
||||||
|
|
||||||
|
Then the following commands have the results described in comments:
|
||||||
|
|
||||||
|
gl-mirror-shell request-push ip1
|
||||||
|
# which is the same as:
|
||||||
|
gl-mirror-shell request-push ip1 gitolite.mirror.slaves
|
||||||
|
# pushes to sam, merry, pippin
|
||||||
|
|
||||||
|
gl-mirror-shell request-push ip1 gollum
|
||||||
|
# pushes only to gollum. Note that gollum is not a member of any of
|
||||||
|
# the slave lists we defined.
|
||||||
|
|
||||||
|
gl-mirror-shell request-push ip1 gitolite.mirror.slaves gollum
|
||||||
|
# pushes to sam, merry, pippin, gollum
|
||||||
|
|
||||||
|
gl-mirror-shell request-push ip1 gitolite.mirror.slaves gitolite.mirror.hourly
|
||||||
|
# pushes to sam, merry, pippin, legolas
|
||||||
|
|
||||||
|
gl-mirror-shell request-push ip1 gitolite.mirror.all
|
||||||
|
# pushes to sam, legolas, gimli, merry, pippin
|
||||||
|
|
||||||
|
The last two examples show recursive expansion with order-preserving
|
||||||
|
duplicate removal (hey there's now a published conference paper on
|
||||||
|
gitolite, so we have to use jargon *somewhere* or they won't accept
|
||||||
|
follow-on papers!).
|
||||||
|
|
||||||
|
If you do something like this:
|
||||||
|
|
||||||
|
config gitolite.mirror.nightly = "gimli gitolite.mirror.nightly"
|
||||||
|
|
||||||
|
or this:
|
||||||
|
|
||||||
|
config gitolite.mirror.nightly = "gimli gitolite.mirror.hourly"
|
||||||
|
config gitolite.mirror.hourly = "legolas gitolite.mirror.nightly"
|
||||||
|
|
||||||
|
you deserve what you get.
|
||||||
|
|
||||||
|
2. If you want to start a **foreground** job, the syntax is `gl-mirror-shell
|
||||||
|
request-push ip1 -fg gollum`. Foreground mode requires one (and only one)
|
||||||
|
slave name -- you cannot send to an implicit list, nor to more than one
|
||||||
|
slave.
|
||||||
|
|
||||||
|
3. Cronjobs and custom mirroring schemes are now very easy to do. Use either
|
||||||
|
of the command forms above and write a script around it. Appendix A
|
||||||
|
contains an example setup.
|
||||||
|
|
||||||
|
4. Once in a while a slave will realise it needs an update, and wants to ask
|
||||||
|
for one. It can run this command to do so:
|
||||||
|
|
||||||
|
ssh sam request-push ip2
|
||||||
|
|
||||||
|
If the requesting server is not one of the slaves listed in the config
|
||||||
|
variable gitolite.mirror.slaves on the master, it will be rejected.
|
||||||
|
|
||||||
|
This is always a foreground push, reflecting the fact that the slave may
|
||||||
|
want to know why their push errored out or didn't work last time or
|
||||||
|
whatever.

|
#### the `conf/gitolite.conf` file
|
||||||
|
|
||||||
|
One goal I have is to minimise the code changes to "core" gitolite due to
|
||||||
|
this, so all repo-specific mirror settings are stored as `git config`
|
||||||
|
variables (you know you can specify git config variables in the gitolite
|
||||||
|
config file right?). These are:
|
||||||
|
|
||||||
|
* `gitolite.mirror.master`
|
||||||
|
|
||||||
|
The name of the server which is the master for this repo. Each server
|
||||||
|
will compare this with `$GL_HOSTNAME` (from its own rc file) to
|
||||||
|
determine if it's the master or a slave. Here're the possible values:
|
||||||
|
|
||||||
|
* **undefined** or `local`: this repo is local to this server
|
||||||
|
* **same** as `$GL_HOSTNAME`: this server is the "master" for this
|
||||||
|
repo. (The repo is "native" to this server).
|
||||||
|
* **not same** as `$GL_HOSTNAME`: this server is a "slave" for the
|
||||||
|
repo. (The repo is a non-native on this server).
|
||||||
|
|
||||||
|
* `gitolite.mirror.slaves`
|
||||||
|
|
||||||
|
Ignored for non-native repos. For native repos, this is a space-separated
|
||||||
|
list of servers to push to from the `post-receive` hook.
|
||||||
|
|
||||||
|
Clearly, you can have different sets of slaves for different repos (again,
|
||||||
|
see "discussion" section later for more on this).
|
||||||
|
|
||||||
|
* `gitolite.mirror.redirectOK`
|
||||||
|
|
||||||
|
See the section on "redirecting pushes"
|
||||||
|
|
||||||
|
* In addition, you can create your own slave lists, named whatever you want,
|
||||||
|
except they have to start with `gitolite.mirror.`. The section on
|
||||||
|
"commands to (re-)sync mirrors" has some examples.
|
||||||
|
|
||||||
|
<a name="_redirecting_pushes"></a>
|
||||||
|
|
||||||
|
### redirecting pushes
|
||||||
|
|
||||||
|
**Please read carefully; there are security implications if you enable this
|
||||||
|
for mirrors NOT under your control**.
|
||||||
|
|
||||||
|
When a user pushes to a non-native repo, it is possible to transparently
|
||||||
|
redirect the push to the correct master server. This is a very neat feature,
|
||||||
|
because now all your users just use one URL (the mirror nearest to them).
|
||||||
|
They don't need to know where the actual master is, and more importantly, if
|
||||||
|
you and the other admins change it, they don't need to know it changed!
|
||||||
|
|
||||||
|
The `gitolite.mirror.redirectOK` config variable decides where this
|
||||||
|
redirection is OK. If it is set to 'true', any valid 'slave' can redirect an
|
||||||
|
incoming non-native push from a developer. Otherwise, it contains a list of
|
||||||
|
slaves that are permitted to redirect pushes (this might happen if you don't
|
||||||
|
trust some of your slaves enough to accept a redirected push from them).
|
||||||
|
|
||||||
|
This check needs to pass on both the master and slave servers; both have a say
|
||||||
|
in deciding if this is allowed. (The master may have real reasons not to
|
||||||
|
allow this; see below. I cannot think of any real reason for the *slave* to
|
||||||
|
disable this, but it's there in case some admin doesn't like it).
|
||||||
|
|
||||||
|
There are some potential issues that you MUST consider before enabling this:
|
||||||
|
|
||||||
|
* (security) If the slave and master server are so different or autonomous
|
||||||
|
that a user, say "alice", on the slave is not guaranteed to be the same
|
||||||
|
one as "alice" on the master, then the master admin should NOT enable this
|
||||||
|
feature.
|
||||||
|
|
||||||
|
This is because, in this scheme, authentication happens on the slave, but
|
||||||
|
authorisation is on the master. The slave-authenticated userid (alice) is
|
||||||
|
passed to the master.
|
||||||
|
|
||||||
|
(If you know ssh well enough, you know that the ssh authentication has
|
||||||
|
already happened, so all we can do is ensure authorisation happens with
|
||||||
|
whatever username we know so far).
|
||||||
|
|
||||||
|
* If your slave is out of sync with the master for whatever reason, then the
|
||||||
|
user will get confusing results. A `git fetch` may say everything is
|
||||||
|
upto-date but the push fails saying it is not a fast-forward push. (Of
|
||||||
|
course there's a way to fix this; see the "commands to (re-)sync mirrors"
|
||||||
|
section above).
|
||||||
|
|
||||||
|
* We cannot redirect non-git commands like ADC, setperms, etc because we
|
||||||
|
don't really have a way of knowing what repo he's talking about (different
|
||||||
|
commands have different syntaxes, some have more than one reponame...).
|
||||||
|
Any user who needs to do that should access the end server directly. It
|
||||||
|
should be easy enough to write an ADC to do the forwarding, in case the
|
||||||
|
slave server is the only one that can reach the real master due to network
|
||||||
|
or firewall setup.
|
||||||
|
|
||||||
|
Ideally, I recommend that ad hoc repos not be mirrored at all. Keep
|
||||||
|
mirroring for "blessed" repos only.

|

|
|

|
#### problems with the old mirroring model
|
||||||
|
|
||||||
|
The old mirroring model had a single server as the master for *all*
|
||||||
|
repositories. Slaves were effectively only for load-balancing reads, or for
|
||||||
|
failover if the master died.
|
||||||
|
|
||||||
|
This is not good enough for corporate setups where the developers are spread
|
||||||
|
fairly evenly across the world. Some repos need to be closer to some teams
|
||||||
|
(NUMA is a good analogy).
|
||||||
|
|
||||||
|
A model where different repos are "mastered" in different cities is much more
|
||||||
|
efficient here.
|
||||||
|
|
||||||
|
The old model had other rigidities too, though they're not really *problems*,
|
||||||
|
as such:
|
||||||
|
|
||||||
|
* the slaves are just slaves; they can't have any "local" repos.
|
||||||
|
|
||||||
|
* a slave had to carry *all* repos; it couldn't choose to carry just a
|
||||||
|
subset.
|
||||||
|
|
||||||
|
* it implicitly assumed all the mirrors were under the same admin, and that
|
||||||
|
the gitolite-admin repo was itself mirrored too.
|
||||||

<a name="_the_new_mirroring_model"></a>
|
||||||
|
|
||||||
|
#### the new mirroring model
|
||||||
|
|
||||||
|
In the new model, servers can be much more independent and autonomous than in
|
||||||
|
the old model. (Don't miss the side note in the 'repository level setup'
|
||||||
|
section if you prefer the old model).
|
||||||
|
|
||||||
|
The new model has a few pros and cons. The pros come from the flexibility and
|
||||||
|
freedom that mirrors servers get, and the cons come from authorisation being
|
||||||
|
more rigorously checked (for example, a slave will only accept a push if *its*
|
||||||
|
configuration also says that the sending server is indeed the master for this
|
||||||
|
repo).
|
||||||
|
|
||||||
|
* A mirroring operation will not *create* a repo on the mirror; it has to
|
||||||
|
exist before a push happens on the master. Typically, the admin on the
|
||||||
|
slave must create the repo by adding the appropriate lines in his config.
|
||||||
|
|
||||||
|
If your setup is not autonomous (i.e., you're mirroring the admin repo as
|
||||||
|
well) then this happens automatically for normal repos. However,
|
||||||
|
*wildcard repos still won't work as seamlessly as in the old model*; see
|
||||||
|
the first bullet in the 'IMPORTANT cautions' section earlier.
|
||||||
|
|
||||||
|
* The gitolite-admin repo (and config) need not be mirrored. This allows
|
||||||
|
the slave server admin to create site-local repos, without forcing him to
|
||||||
|
create a second gitolite install for them.
|
||||||
|
|
||||||
|
(Site-local repos are useful for purely local projects that need
|
||||||
|
not/should not be mirrored for some reason, or ad-hoc personal repos that
|
||||||
|
developers create for themselves, etc.)
|
||||||
|
|
||||||
|
* Servers can choose to mirror a subset of the repos from one of the bigger
|
||||||
|
servers.
|
||||||
|
|
||||||
|
In the open source world, you can imagine more popular repos (or more
|
||||||
|
popular parts of huge projects like KDE) having more mirrors. Or
|
||||||
|
substitute "more popular" with "larger in size" if you wish
|
||||||
|
(FlightGear-data anyone?)
|
||||||
|
|
||||||
|
In the corporate world it could help with jurisdiction issues if the
|
||||||
|
mirror is in a different country with different laws.
|
||||||
|
|
||||||
|
I'm sure people will find other uses for this. And I'm *positive* the
|
||||||
|
pros will outweigh the cons. If you don't like it, follow the suggestion
|
||||||
|
in the side note somewhere up above, and just forget this feature exists
|
||||||
|
:-)

### appendix A: example cronjob based mirroring
|
||||||
|
|
||||||
|
Let's say you have some repos that are very active. You're pushing halfway
|
||||||
|
across the world every few seconds, but those slaves do not need to be that closely
|
||||||
|
updated, perhaps *because* they are halfway across the world and those guys
|
||||||
|
are asleep ;-)
|
||||||
|
|
||||||
|
You'd like to update them once an hour instead. Here's how you might do that.
|
||||||
|
|
||||||
|
First add this line to the configuration for those repos:
|
||||||
|
|
||||||
|
config gitolite.mirror.hourly = "slave1 slave2 slave3"
|
||||||
|
|
||||||
|
Then write a cron job that looks like this (untested).
|
||||||
|
|
||||||
|
#!/bin/bash
|
||||||
|
|
||||||
|
REPO_BASE=`${0%/*}/gl-query-rc REPO_BASE`
|
||||||
|
|
||||||
|
cd $REPO_BASE
|
||||||
|
find . -type d -name "*.git" -prune | while read r
|
||||||
|
do
|
||||||
|
# get reponame as gitolite knows it
|
||||||
|
r=${r:2}
|
||||||
|
r=${r%.git}
|
||||||
|
|
||||||
|
gl-mirror-shell request-push $r gitolite.mirror.hourly
|
||||||
|
|
||||||
|
# that command backgrounds the push, so you'd best wait a few seconds
|
||||||
|
# before hitting the next one, otherwise you'll have all your repos
|
||||||
|
# going out at once!
|
||||||
|
sleep 10
|
||||||
|
done

||||||

### syncing the mirrors the first time
|
|
||||||
|
|
||||||
This is fine if you're setting up everything from scratch. But if your master
|
|
||||||
server already had some repos with commits on them, you have to manually sync
|
|
||||||
them up once.
|
|
||||||
|
|
||||||
# on foo
|
|
||||||
gl-mirror-sync gitolite@bar
|
|
||||||
# path to "sync" program is ~/.gitolite/src if "from-client" install
|
|
||||||
|
|
||||||
<a name="_switching_over"></a>
|
|
||||||
|
|
||||||
### switching over
|
|
||||||
|
|
||||||
Let's say foo goes down. You want to make bar the main server, and continue
|
|
||||||
to have "baz" be a slave.
|
|
||||||
|
|
||||||
* on bar, edit `~/.gitolite.rc` and set
|
|
||||||
|
|
||||||
$GL_SLAVE_MODE = 0;
|
|
||||||
$ENV{GL_SLAVES} = 'gitolite@baz';
|
|
||||||
|
|
||||||
* **sanity check**: go to your gitolite-admin clone, add a remote for "bar",
|
|
||||||
fetch it, and make sure they are the same:
|
|
||||||
|
|
||||||
git remote add bar gitolite@bar:gitolite-admin
|
|
||||||
git fetch bar
|
|
||||||
git branch -a -v
|
|
||||||
# check that all SHAs are the same
|
|
||||||
|
|
||||||
* inform everyone of the new URL for their repos (see next section for more
|
|
||||||
on this)
|
|
||||||
|
|
||||||
* make sure that if "foo" does come up, it will not immediately start
|
|
||||||
serving requests. You'll be in trouble if (a) foo comes up as it was
|
|
||||||
before, and (b) some developer still had the old URL lying around and
|
|
||||||
started pushing changes to it.
|
|
||||||
|
|
||||||
You could jump in quickly and set `$GL_SLAVE_MODE = 1` as soon as the
|
|
||||||
system comes up. Better still, use extraneous means to block incoming
|
|
||||||
connections from normal users (out of scope for this document).
|
|
||||||
|
|
||||||
<a name="_the_return_of_foo"></a>
|
|

|
|

### the return of foo
|
|
||||||
|
|
||||||
<a name="_switching_back"></a>
|
|
||||||
|
|
||||||
#### switching back
|
|
||||||
|
|
||||||
Switching back is fairly easy.
|
|
||||||
|
|
||||||
* synchronise all repos from bar to foo. This may take some time, depending
|
|
||||||
on how long foo was down.
|
|
||||||
|
|
||||||
# on bar
|
|
||||||
gl-mirror-sync gitolite@foo
|
|
||||||
# path to "sync" program is ~/.gitolite/src if "from-client" install
|
|
||||||
|
|
||||||
* turn off pushes on "bar" by setting slave mode to 1
|
|
||||||
* run the sync once again; this should complete quickly
|
|
||||||
|
|
||||||
* **double check by comparing some the repos on both sides if needed**. You
|
|
||||||
could run the following snippet on all servers for a quick check:
|
|
||||||
|
|
||||||
cd ~/repositories # or wherever $REPO_BASE is
|
|
||||||
find . -type d -name "*.git" | sort |
|
|
||||||
while read r
|
|
||||||
do
|
|
||||||
echo $r
|
|
||||||
git ls-remote $r | sort
|
|
||||||
done | md5sum
|
|
||||||
|
|
||||||
* on foo, set the slave list (or check that it is correct)
|
|
||||||
* on foo, set slave mode off
|
|
||||||
* tell everyone to switch back
|
|
||||||
|
|
||||||
<a name="_making_foo_a_slave"></a>
|
|
||||||
|
|
||||||
#### making foo a slave
|
|
||||||
|
|
||||||
If "foo" does come up in a controlled manner, you might not want to switch
|
|
||||||
back right away. Unless you're doing DNS tricks, users may be peeved at
|
|
||||||
having to do 2 switches.
|
|
||||||
|
|
||||||
If you want to make foo a slave, you know the drill by now:
|
|
||||||
|
|
||||||
* set slave mode to 1 on foo
|
|
||||||
* on bar, add foo as a slave
|
|
||||||
|
|
||||||
# in ~/.gitolite.rc on bar
|
|
||||||
$ENV{GL_SLAVES} = 'gitolite@foo gitolite@baz';
|
|
||||||
|
|
||||||
I think that should cover pretty much everything. I *have* tested most of
|
|
||||||
this, but YMMV.

|
||||||

|
|
||||||
|
|
||||||
<a name="_URLs_that_your_users_will_use"></a>
|
|
||||||
|
|
||||||
### URLs that your users will use
|
|
||||||
|
|
||||||
Unless you play DNS tricks, it is more than likely that your users would have
|
|
||||||
to change the URLs they use to access their repos if you change the server
|
|
||||||
they push to.
|
|
||||||
|
|
||||||
I cannot speak for the plethora of git client software out there but for
|
|
||||||
normal git, this problem can be mitigated somewhat by doing this:
|
|
||||||
|
|
||||||
* in `~/.ssh/config` on my workstation, I have
|
|
||||||
|
|
||||||
host gl
|
|
||||||
hostname=primary.server.ip
|
|
||||||
user=gitolite
|
|
||||||
|
|
||||||
* all my `git clone` commands use `gl:reponame` as the URL
|
|
||||||
|
|
||||||
* if the primary goes down, and I have to access the secondary, I just
|
|
||||||
change the `hostname` line in `~/.ssh/config`.
|
|
||||||
|
|
||||||
That's it. Every clone of every repo used anywhere in this userid is now
|
|
||||||
changed.
|
|
||||||
|
|
||||||
To repeat, this may or may not work with all the git clients that exist (like
|
|
||||||
jgit, or any of the GUI tools, and especially if you're on Windows).
|
|
||||||
|
|
||||||
If anyone has a better idea, something that works more universally, I'd love
|
|
||||||
to hear it.

|
gl-tool add-mirroring-peer git@server.company.com.pub

As above, but the given key will invoke 'gl-mirror-shell' instead of the
|
||||||
|
usual 'gl-auth-command'. This is meant to be a server-to-server key, allowing
|
||||||
|
(in this example), the gitolite server called 'git@server.company.com' to
|
||||||
|
access this server for mirroring operations.
