The "msysgit doesnt have 'comm'" commit (from 2 days ago), had 2 bugs:
- (smaller) the "+++" which was part of the diff header was triggering
a spurious rc file "new variables" warning, but there were no actual
variables to update
- (bigger) worse, the grep command, when there were no matches,
coupled with the "set -e" to kill the program right there (ouch!)
The way pubkey files are handled by gitolite, this could be used by a
repo admin to get shell access. It's always been there as an
undocumented emergency mechanism for an admin who lost his shell keys or
overwrote them due to not understanding ssh well enough (and it has been
so used at least once).
But not any more...
Like the @SHELL case, this reflects a shift away from treating people
with repo admin rights as eqvt to people who have shell on the server,
and systematically making the former lesser privileged than the latter.
While in most cases (including my $DAYJOB) these two may be the same
person, I am told that's not a valid assumption for others, and there've
been requests to close this potential loophole.
I know hardly anyone is using delegation, but if you find yourself
locked out from pushing because of this one little thing, do this:
* on your gitolite-admin clone, add the required lines per this patch,
and commit
* on the server, edit ~/.gitolite/conf/gitolite.conf-compiled.pm, and
delete the following line
'NAME_LIMITS' => 1
from the entry for "gitolite-admin" (if you don't know what that
means delete *all* such lines) and save the file
* back on your admin repo clone, do a push
Stop conflating the privilege to push changes to the admin repo with the
privilege to get a shell on the server.
Please read doc/6 carefully before upgrading to this version. Also
please ensure that the gitolite key is *not* your only means to get a
command line on the server
Currently, a line like
RW foo = user1
allows user1 to push any ref that contains the string refs/heads/foo.
This includes refs like
refs/heads/foo
refs/heads/foobar
refs/heads/foo/bar
which is fine; that is what is intended. (You can always use foo$
instead of foo if you want to prevent the latter two).
Similarly,
RW refs/foo = user1
allows
refs/foo
refs/foobar
refs/foo/bar
Now, I don't see this as a "security risk" but the fact is that this
allows someone to clutter your repo with junk like
refs/bar/refs/heads/foo
refs/heads/bar/refs/heads/foo
(or, with the second config line example,
refs/bar/refs/foo
refs/heads/bar/refs/foo
)
My personal advice is if you find someone doing that intentionally, you
should probably take him out and shoot him [*], but since now *two*
people have complained about this, here goes...

[*] you don't have to take him out if you don't want to
Support config file including using:
include "filename"
If filename is not an absolute path, it is looked from the
$GL_ADMINDIR/conf/ directory.
For security reasons include is not allowed for fragments.

This is a backward incompatible change. If you are using delegation and
you upgrade to this version, please do the following:
* change your gitolite.conf file to use the new syntax (see
doc/5-delegation.mkd in this commit)
* for each branch "foo" in the gitolite-admin repo, do this:
# (on "master" branch)
git checkout foo -- conf/fragments/foo.conf
* git add all those new fragments and commit to master
* delete all the branches on your clone and the server
# again, for each branch foo
git branch -D foo
git push origin :foo
(this commit will probably get reverted after a suitable period has
elapsed and no one is likely to still be using the old syntax).
Forgetting to change it to NAME/ after is a security issue -- you end up
permitting stuff you don't want to!
This commit allows the old syntax but prints a warning
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.
This reverts commit 6576e82e33.
On oddball configs, where the shell key is reused as the gitolite key by
smart( people|-alecks), the ls-remote stops the program dead, preventing
the "git add" and "git commit" that seed the admin repo.
This makes extra work in terms of fixing it after the fact; removing it
makes the install go further, and all you need to do is (1) delete the
first line from ~/.ssh/authorized_keys on the server and (2) back on the
client do a "git clone gitolite:gitolite-admin".
OK so it needs to be removed. Explaining that was the easy part! The
hard part is explaining why removing it is harmless.
Look at the commit tree around that commit, and see that the commit
before that (b78a720) was partially reverted in e7e6085. b78a720
removed the new_repo call from compile, forcing it to happen only on
auth, which forced this workaround for seeding the admin repo.
Since e7e6085 reverted that part of b78a720, giving back new_repo
functions to compile, this line of code wasn't doing any good. QED and
all that :)
for those not yet able to upgrade (or until I merge this into the branch
you care about), if you have a repo called, say "bk2git", just refer to
it as "bk2git.git" in the clone command!
[Thanks to Mark Frazer for finding this...]
"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

".../gl-auth-command username" is the normal command that authkeys
forces, and this prevents that key from being used to get a shell.
We now allow the user to get a shell if the forced command has a "-s"
before the "username", like ".../gl-auth-command -s sitaram".
(Now that a plain "ssh gitolite" gets you a shell, there's a new "info"
command that such privileged keys can use to get basic access info).
Thanks to Jesse Keating for the idea! I can't believe this never
occurred to me before, but I guess I was so enamoured of my "innovation"
in converting what used to be an error into some useful info I didn't
think a bit more :/
Looks like I'd forgotten this when I did the autoviv code. Repos
created via gl-compile (when you add a new repo to the config file and
push) worked fine, but repos created via gl-auth (when you autoviv a
repo, wild or not) did not.
This *should* be merged into wildrepos soon after testing; wildrepos
will have a lot more autoviv-ing than master.
The admin repo's post-update hook needs to know where $GL_ADMINDIR is,
and we had a weird way of doing that which depended on gl-install
actually munging the hook code.
We also always assumed the binaries are in GL_ADMINDIR/src.
We now use an env var to pass both these values. This removes the weird
dependency on gl-install that the post-update hook had, as well as make
running other programs easier due to the new $GL_BINDIR env var.
Git repository configurations can be set/unset by declaring "config"
lines in "repo" stanzas in gitolite.conf. For example:
repo gitolite
config hooks.mailinglist = gitolite-commits@example.tld
config hooks.emailprefix = "[gitolite] "
config foo.bar = ""
config foo.baz =
The firs two set (override) the values. Double quotes must be used to
preserve preceding spaces. Third one sets an empty value and the last
removes all keys.

we had usurped the email style syntax to separate multiple keys
belonging to the same person, like sitaram@desktop.pub and
sitaram@laptop.pub. If you have so many users that you need the full
email address to disambiguate some of them (or you want to do it for
just plain convenience), you couldn't.
This patch fixes that in a backward compatible way. See
doc/3-faq-tips-etc.mkd for details.
@all in a deny rule doesnt work as it might look in the config file,
because @all rights are checked last. This is fine if you dont have any
DENYs (and so rule order doesn't matter), but with DENY it causes some
problems.
I never bothered to document it because I did not expect that any repo
that is "serious" enough to have deny rules *at all* should then allow
*any* kind of "write* access to @all. That's a very big contradiction
in terms of paranoia!
Translation: this will not be supported. Don't bother asking. You know
who you are :)
all of this is prep for the upcoming, all-new, chrome-plated,
"wildrepos" branch :)
- many variables go to gitolite.pm now, and are "our"d into the other
files as needed
- new functions parse_acl, report_basic to replace inlined code
consider:
repo = "some desc" # some comment
(and note that the regex for recognising a description expects that
dblquote to be the *last* character on the line)
part of comment on b78a720cee:
The only reason it's getting into master is because it looks cool!
I hate it when something that looks cool doesn't work right :(
creating a repo on gitolite-admin push is *needed* in order to get
descriptions and export-ok files to work right
Well, something even more outrageous than deny rules and path-based
limits came along, so I decided that "rebel" was actually quite
"conformist" in comparision ;-)
Jokes apart, the fact is that the access control rules, even when using
deny rules and path-limits, are still *auditable*. Which means it is
good enough for "corporate use".
[The stuff that I'm working on now takes away the auditability aspect --
individual users can "own" repos, create rules for themselves, etc.
So let's just say that is the basis of distinguishing "master" now.]
Summary: much as I did not want to use "excludes", I guess if we don't put the
code in "master" it's OK to at least *write* (and test) the code!
See the example config file for how to use it.
See "design choices" section in the "faq, tips, etc" document for how it
works.
