The old method of passing in usergroup info had some problems, which are
now fixed. It is also much easier to use now -- no more "wrapper"
script, plus it should work identially whether you use sshd or httpd.
See doc/big-config.mkd for details on the new method.
----
Notes on problems with the old method:
The old method for passing in usergroup info consisted of tacking them
on as extra arguments to gl-auth-command, after the username.
However, there are some problems with this method.
Some actions in gitolite look for permissions for users other than the
invoking user. Determining permissions for gitweb and daemon is one.
An admin asking for "info" on some other user, is another.
However, the list of groups sent in via the command line
pertains only to the invoking user, so these actions don't work
correctly. They may even pick up the wrong permissions.
What it all boils down to is that we need group information for any user
dynamically, instead of being passed a (static) list just for the
invoking user.
By default, @all does not include gitweb and daemon, but if that's what
you want, you can make it happen... see GL_ALL_INCLUDES_SPECIAL
variable in conf/example.gitolite.rc
I'm an idiot. I say I won't do it, then I go and do it anyway.
Fortunately, in this case, the code and execution remain exactly the
same for people who do not set $GL_PERFLOGT in the rc file, so it's
tolerable.
<evil grin> People who want even more than this can contact Greg Lonnon
(see the mailing list archives at
http://groups.google.com/group/gitolite for an obfuscated but easy to
guess email address) ;-)
- new GL_GITCONFIG_WILD to gate it
- new sub to do all the hard work (refactored from a few lines in
compile)
- split the call from "compile" into two sets -- first for non-wild,
then for wild
This ensures that after a "compile" (admin push) all git configs are
applied.
TODO: apply them when a new wild repo is created by a user, and then on
the "fork" (admin-defined command)
conf/example.gitolite.rc
- "slave mode" flag to disable pushes and "list of slaves"
hooks/common/post-receive.mirrorpush
- code to push to the mirror, creating the repo if needed
src/mirror-shell
- shell for master pushing to a slave, because we don't actually want
to go through gitolite itself, yet we have to take care of
$REPO_BASE being wherever. And of course we have to set
GL_BYPASS_UPDATE_HOOK to 1 for the push to happen!
src/gl-mirror-sync
- manually runnable program to sync from current server to another
allows a default 'setperms' string to be set for new wildcard
repositories.
Also, fix a bug in the fork script where a failure in the git command
would still cause the rest of the script to attempt to run.
This is what I *should* have done back then; thanks to Jeff Mitchell for
pointing out a problem with the old method.
The old one is *definitely* a kludge. <shamefaced grin>
If you have many thousands of repos and users, neatly organised into
groups, etc., the normal gitolite fails. (It actually runs out of
memory very fast while doing the "compile" when you push the config, due
to the number of combinations of repo/user being stored in the hash!)
This commit series will stop doing that if you set $GL_BIG_CONFIG = 1 in
the rc file.
Some notes:
- deny rules will still work but somewhat differently -- now they must
be placed all together in one place to work like before. Ask me for
details if you need to know before I get done with the docs
- I've tested most of the important features, but not every single
nuance
- the update hook may be a tad less efficient now; we can try and
tweak it later if needed but it shouldn't really hurt anything
significantly even now
- docs have not been written yet
(as if we didn't already have enough programs with the word "install" in
their names!)
Anyway, this does what an RPM or a DEB would do -- basically implement
the instructions in Appendix C of doc/0.
You can use this to do a system-wide install if your distro isn't as
smart, forward-looking, and uptodate as Fedora ;-)
Clone the repo somewhere, cd to it, and run, for example:
sudo src/gl-system-install /usr/local/bin /var/gitolite/conf /var/gitolite/hooks
or something like that. See doc/0 for details. Run without arguments
for help.
This commit series allows an admin to designate a set of commands that
users can run. For example, he can allow users to delete a repo that
they have created:
ssh git@server rmrepo foo/me/bar
or fork (to use github's terminology) a repo they have "R" access to,
into a new one they have "C" access to:
ssh git@server fork foo/someone-else/bar foo/me/bar

(this commit)
- (rc) new variable $GL_ADC_PATH; without this none of this is enabled
- (pm) new helper routine "cli_repo_rights" to get rights/ownership
from outside
- (auth) call $GL_ADC_PATH/$cmd if it exists
Having to specify "D" separately from RW or RW+ was cumbersome, and
although I don't actually use this feature, I can see the point.
One way to think of this is:
- RW and RW+ were the only existing branch level rights
- it doesnt make sense to have D rights without W (hence RW) rights
- so we simply suffix a D to these if required.
Thus you can have RW, RW+, RWD, RW+D.
I hope the (hopefully few) of you who have started to use this feature
will convert your configs when you next upgrade to "pu".
I now regret pushing the previous syntax to master too quickly -- lots
of people use master only, and on the next promotion of pu the syntax
will change. To reduce this exposure, this change will be promoted to
master very soon.
Previous implementations of "give shell access to some gitolite users"
feature were crap. There was no easy/elegant way to ensure that someone
who had repo admin access would not manage to get himself shell access.
Giving someone shell access requires that you should have shell access
in the first place, so the simplest way is to enable it from the server
side only.
So now that we decided to do that, we may as well prepare for other,
future, commands by starting a server-side utility program with
sub-commands (the only current one being "shell-add")
normally, RW+ means permission to rewind or delete.
Now, if you use "D" permission anywhere in a repo config, that means
"delete" and RW+ then means only "rewind", no delete.
- no need to put it at the end of the config file now, yeaaay!
- @all for @all is meaningless and not supported. People asking will
be told to get a life or use git-daemon.
- NAME/ limits for @all repos is ignored for efficiency reasons.
There are some disadvantages to the old-style personal branch scheme.
It only allows one specific pattern (of refname) to be used, forces that
pattern to be applicable to *all* repos in the entire config, and
requires editing the rc file (on the server) to be edited to achieve
this.
In other words, it's a very blunt instrument...
The new style depends on using lines like this within a specific repo
config:
RW+ personal/USER/ = @userlist
The important thing is that the "branch" name should contain `/USER/`
(including the slashes). Access is still determined by the right hand
side of course.
This gives you the following advantages:
- allow it only for repos that need it
- allow different patterns to be used for different repos
- allow *multiple* patterns; just add more than one such line
- allow the pattern to have suffixes (eg: foo/USER/bar)
Gitolite allows you to set git repo options using the "config" keyword;
see conf/example.conf for details and syntax.
However, if you are in an installation where the repo admin does not
(and should not) have shell access to the server, then allowing him to
set arbitrary repo config options *may* be a security risk -- some
config settings may allow executing arbitrary commands.
This patch fixes it, introducing a new RC variable to control the
behaviour. See conf/example.gitolite.rc for details
The wildrepos branch has been merged into master, and deleted. It will no
longer exist as a separate branch. Instead, a new variable
called $GL_WILDREPOS has been added which acts as a switch; when
off (which is the default), many wildrepos features are disabled.
(the "C" permissions, and the getperms (etc.) commands mainly).
Important: if you are using wildrepos, please set "$GL_WILDREPOS = 1;" in
the RC file when you upgrade to this version (or just before you do the
upgrade).
lots of conflicts, esp in gl-auth-command, due to refactoring the
"special commands" stuff on master

great idea by Robin Smidsrød: since users are already capable of
authenticating themselves to gitolite via ssh keys, use that to let them
set or change their own HTTP passwords (ie, run the "htpasswd" command
with the correct parameters on behalf of the "git" user on the server)
code, rc para, and documentation. In fact everything except... ahem...
testing ;-)
and while we're about it, we also reorganised the way these helper
commands (including the venerable "info" are called)
This is actually a pretty big deal, and I am seriously starting wonder
if calling this "gito*lite*" is justified anymore.
Anyway, in for a penny, in for a pound...
This patch implements a generic way to allow access control for external
commands, as long as they are invoked via ssh and present a server-side
command that contains enough information to make an access control
decision.
The first (and only, so far) such command implemented is rsync.
Please read the changes in this commit (at least the ones in conf/ and
doc/) carefully.
Stop conflating the privilege to push changes to the admin repo with the
privilege to get a shell on the server.
Please read doc/6 carefully before upgrading to this version. Also
please ensure that the gitolite key is *not* your only means to get a
command line on the server
Gitolite allows you to restrict changes by file/dir name. The syntax
for this used "PATH/" as a prefix to denote such file/dir patterns.
This has now been changed to "NAME/" because PATH is potentially
confusing.
While this is technically a backward-incompatible change, the feature
itself was hitherto undocumented, and only a few people were using it,
so I guess it's not that bad...
Also added documentation now.
"repo @all" can be used to set permissions or configurations for all
already defined repos. (A repository is defined if it has permission
rules associated, empty "repo" stanza or "@group=..." line is not enough.)
For example to allow a backup user to clone all repos:
# All other configuration
[...]
repo @all
R = backup
