Sitaram Chamarty 02cee1d5cf wildrepos: expanded access reporting
This feature has *no* warranty, and so no documentation.  Not more than
this transcript anyway.

config file:

    @prof = u1
    @TAs = u2 u3
    @students = u4 u5 u6

    repo    assignments/CREATER/a[0-9][0-9]
        C   =   @students
        RW+ =   CREATER
        RW  =   WRITERS @TAs
        R   =   READERS @prof

Sitaram Chamarty f620044156 wildrepos: implement getperms and setperms 2009-12-06 20:36:15 +05:30
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 e6da853082 auth, compile, pm: good bit of refactoring
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

Sitaram Chamarty c3b5e3b1af compile, pm: factor out new repo creation
...also wrap_chdir, wrap_open, $ABRT, and $WARN

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.
