Sitaram Chamarty a472bf30df compile: tighten up the 'git config' feature
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

Sitaram Chamarty 388f4d873d (IMPORTANT; read this in full) no more "wildrepos"
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).

martin f. krafft 0a7fa6c6b5 Tell gitweb about repo owner via git-config
Gitolite uses projects.list to set the owners for gitweb's use.
Unfortunately, this does not work for gitweb setups that set
$projectroot to a directory, thus generating the list of
repositories on the fly.

This patch changes that: gitolite now writes the gitweb.owner
configuration variable for each repository (and properly cleans up after
itself if the owner is removed).

The patch causes gitolite not to write the owner to projects.list
anymore, as this would be redundant.

The owner also needs no longer be escaped, so this patch removes the
poor man's 's/ /+/g' escaping previously in place.

Note that I am not a Perl coder. Thus there are probably better ways to
implement this, but at least it works.

Sitaram Chamarty 98a4c79dce (read this in full) access control for non-git commands running over ssh
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.

Sitaram Chamarty 645ab77af5 compile: disallow multiple pubkeys in one file
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.

Sitaram Chamarty 08ef3555a1 deprecation warning about old style PATH/ syntax
(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

Sitaram Chamarty 7124faa9f3 NAME-based restrictions
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

Sitaram Chamarty 981d693dec Revert "compile, parse_acl: treat foo/CREATER (no regex metas) correctly"
This reverts commit 33fc0a7e9f.

Was causing too much trouble with access reporting (basic and expanded)
because of the extra ^ at the start...

The paranoia referred to in that commit was this sequence:

  - admin creates a named (non wildcard) repo using config file push
  - somehow that gets deleted (OS error, corruption, ...)
  - admin just asks anyone with a current repo to push it to auto-revive
    it (because we allow people with "W" access to non-wildcard repos to
    auto-viv repos)
  - if you're treating this the same as a wildcard creation, you end up
    making this guy the "creater" of that repo, which means he can add
    users etc...

We resolve that paranois by disallowing autoviv of "W" access repos at
all...  Only "C" access repos can be autovived by a user (this will be
in the next commit)

Sitaram Chamarty b7404aa772 auth/install/pu-hook: pass ADMINDIR and BINDIR via ENV
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.

Sitaram Chamarty 33fc0a7e9f compile, parse_acl: treat foo/CREATER (no regex metas) correctly
Teemu's testing brought up a situtation I had not anticipated:
"repo foo/CREATER" looks like a non-regex, and its creation then (a)
goes by "W" permissions instead of "C" permissions, and (b) the
creater's name does not get recorded (no gl-creater file).

    SIDE NOTE: one way is to reduce the paranoia, and just put the
    creater name in anyway.  Treat a repo created from gl-auth as a
    wildcard-matched autovivified repo, because the *other* kind would
    have actually got created by gl-compile anyway.

    However, I can think of *one* very far-out situation where this
    could backfire on an unwary admin, and I'm paranoid :-)

So we need to force it to look like a regex.  Moving the line-anchoring
from `parse_acl` to gl-compile sounded fine, until I realised that the
"$" isn't easy.  Backslashitis, bigtime, plus the single/double quote
tricks we're playing with the dumped hash adds its own complexities.

Best of both worlds, promote the "^" to gl-compile, keep the "$" where
it is...!

Teemu Matilainen 3403d40d0e Add support for repo configurations
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.

Sitaram Chamarty 4441ed82e4 compile: allow full email addresses as usernames
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.

Sitaram Chamarty f49eddd660 wildrepos: teach auth and update hook about wildcard repos
- new_repo now takes a "creater" parameter; if given, this user is
    recorded (in a file called "gl-creater") as the creater of the repo.
    Only applicable to wildcards

  - repo_rights reads "gl-creater" and "gl-perms" to tell you who
    created it, and whether you (the $user) are in the list of READERS
    or WRITERS

    **NOTE** that the mechanism to create/update gl-perms has not been
    written yet... (as of this commit)

  - parse_acl takes 4 more arguments, all optional.  The repo name we're
    interested in (set by all except the access reporting function), and
    the names to be interpolated as $creater, $readers, writers

  - report_basic now knows about the "C" permission and shows it

  - auth now autovivifies a repo if the user has "C" and it's a wildcard
    match, or (the old case) the user has "W" and it's not a wildcard.
    In the former case, the creater is also set

IMPLEMENTATION NOTES:

  - the Dumper code now uses a custom hash key sort to make sure
    $creater etc land up at the *end*

  - a wee bit of duplication exists in the update hook; it borrows a
    little code from parse_acl.  I dont (yet) want to include all of
    gitolite.pm for that little piece...

Sitaram Chamarty 77306567e9 wildrepos: teach compile the new syntax
There's a new "C" permission to let someone *create* a repo that matches
the pattern given in the "repo ..." line.  If the word CREATER appears
in the repo pattern, then that is forced to the actual user performing
that operation.

Something like this (we'll discuss READERS and WRITERS later):

    repo personal/CREATER/.+
    C           =   @staff
    R   [foo]   =   READERS
    RW  [bar]   =   WRITERS
    ...various other permissions as usual...

Delegation checking also changes quite a bit... see comments in code

Implementation: there's also a sneaky little trick we're playing here
with the dumped hash

Sitaram Chamarty b78a720cee auth/compile: auto-vivify is default now, so:
the "create a new repo" code moves from compile to auth.

Only someone who has W access can create it, but he can do so even on a
"R" operation (like clone or ls-remote).

This is a pre-requisite for rebel's wildcard repos, where
autovivification is the only way you can create arbitrary repos matching
a pattern.

The only reason it's getting into master is because it looks cool!

OK that's a lie; the real reason is to keep the two branches as similar
as possible, though they;ve diverged quite a bit since the "only
one-line difference" days where "rebel" just meant "deny/exclude"
rules!)

You can now add your own hooks into src/hooks/ and they get propagated

be avoided (and I was feeling the same way).  I've also been
inconsistent with that "gl-" prefix, so I cleaned that up, and the 00-

Sitaram Chamarty 78d02e1437 the rc file can now be in one of 2 places...
Packaging gitolite for debian requires the rc file to be in /etc/gitolite.
But non-root installs must still be supported, and they need it in $HOME.

This means the rc file is no longer in a fixed place, which needs code to find
the rc file first.  See comments inside new file 'gitolite.pm' for details.

The rest of the changes are in the other programs, to replace the hard-coded
rc filename with a call to this new code.
