Sitaram Chamarty 6386d8ca2f gl-reflog adc gains 'usage', loses some crappy warnings
(actually these warnings can come in many other situations; I just
noticed them when testing this adc)

Sitaram Chamarty db0485fa7e new method for passing usergroup info (warning: minor backward compat breakage)
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.

Sitaram Chamarty 595410aa55 (http) first level error reporting now works
I didn't know that remote-curl.c requires 200 OK even if you want to
report an error.

With Ilari's patch at [1] you'll get a more readable message but it is
still good enough now.

Sitaram Chamarty f4e011226a (http) issues of $HOME, startup (birth!), and death
- deal with issues of HOME not being available...

Sitaram Chamarty 52e0ed3488 (http) auth: handle REQUEST_URI and friends
TODO: if the verb doesn't actually contain "git-receive-pack", I am
assuming it is some sort of read.  The list in services[] in
http-backend.c does not seem to look like any other verb is a "write";
need to check this with someone.

For normal git commands:
  - PATH_INFO gives you the repo name
  - REQUEST_URI gives you the verb
  - we construct a fake SSH_ORIGINAL_COMMAND so the rest of the
    processing does not have to change

For our special commands:
  - PATH_INFO is actually the verb
  - QUERY_STRING has the parameters
  - we again fake out the SSH_ORIGINAL_COMMAND
  - we print the extra HTTP headers in anticipation of the actual output

Either way, we also fake out the SSH_CONNECTION so that the IP address
can get logged ok

And of course REMOTE_USER is now the incoming userid

Finally, at the end, we exec GIT_HTTP_BACKEND instead of the normal one

Sitaram Chamarty 6b9e75dfcb allow @all to also include gitweb and daemon
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

2010-08-24 17:51:33 +05:30
Sitaram Chamarty 6e2db12302 allow @groups in setperms command also
This should hopefully be the final step in making wildrepos as close to
normal repos as possible.  You can now do pretty much anything with them
that you can do with normal repos [1]

Implementation notes:

  - compile puts out %groups into the compiled config file regardless of
    GL_BIG_CONFIG because this feature needs it
  - wild_repo_rights caches %groups because the part of the %groups hash
    we care about will not change between calls in the same run

----

[1] **except** use the full-blown config file syntax within the gl-perms
    file :-)  I don't plan to do that; it's too complicated! [2]

[2] yeah yeah I know -- famous last words!
2010-08-21 13:04:13 +05:30
Sitaram Chamarty 3a8f32ac9b minor fixups to the "gitweb/daemon from setperms" code...
- fork was not printing a newline after the permissions
  - "add_del_line" to properly handle that damn projects.list file!
2010-08-20 23:09:11 +05:30
Sitaram Chamarty 648676faec gitweb and daemon should now work even from within setperms
modifications:

  - call setup_gitweb_access and setup_daemon_access from with
    get_set_perms so when the user sets a perm explicitly it works
  - in setup_gitweb_access, do not delete description file or
    gitweb.owner if the repo is wild
  - make the "fork" adc set gitweb.owner *and* call setperms using
    GL_WILDREPOS_DEFPERMS
  - add tests

bug fixes:

  - gl-auth did not even *look* at GL_WILDREPOS_DEFPERMS when
    auto-"C"reating a wild repo; fixed
  - setup_gitweb_access did not delete the description file as
    consistently as it deleted the owner

what will NOT work:

  - removing gitweb permissions does not clear the name from
    "projects.list".  That's complicated, so just wait till the next
    "compile" to make this happen

(thanks to Jefferai for driving this...)

----

mildly puzzling:

    for some strange reason, after a "git ls-remote ...try3" in t58,
    instead of not creating a "description" file, we started seeing a
    73-byte file containing this message:

    Unnamed repository; edit this file 'description' to name the repository.

Sitaram Chamarty da210f21bd log elapsed time
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) ;-)

Sitaram Chamarty 79f0a5fd52 (big one!) more than one wildcard may match a repo...
plus it can also be matched by a normal repo line.  In other words, with

    repo foo/bar
        RW  =   u1

    repo foo/..*
        RW  =   u2

user u2 has access to foo/bar (the non-wild does not cause the wild to
be completely ignored any longer)

implementation notes:

    get_memberships:

      - no more highlander ("there can only be one") for patterns in
        @repo_plus
      - return $wild as a space-separated list of matched patterns

    collect_repo_patts:

      - as of the last change to this section of code it appears we
        weren't using the values anyway, but I had forgotten :-)

    repo_rights: (big change: $wild no longer implies $creator present,
    or vice versa)

      - new type of "creator" (like "was_sitaram") is now possible
2010-08-11 22:38:17 +05:30
Sitaram Chamarty f21e7780a1 fix up gitweb, daemon, for wild + big-config
Implementation notes:

  - %repo_config is now "our", not "my"
  - collect_repo_patts now uses repo_rights to get the name of the wild
    card repo (if any) that pertains to the physical $repo, instead of
    all that new code (duh!)
  - new "can_read(repo, user)" sub (to help daemon and gitweb use)
  - the "convenience copy on steroids" thing now copies %repo_config
    also, not just %repos.  This makes setup_repo_configs simpler
  - $creator gets substituted into %groups also; we need that now that
    we (%repos and %groups) are working closer together :)
2010-08-11 22:38:16 +05:30
Sitaram Chamarty 509c73b888 gitweb/daemon now work for wild repos also
(thanks to Kevin Fleming for the need/use case)

TODO: tests
TODO: proper documentation; meanwhile, just read this:

  - you can give gitweb and daemon read rights to wild card repos also,
    and it'll all just work -- when a new repo is 'C'reated, it'll pick
    up those rights etc

  - you can assign descriptions (and owners) to individual repos as
    before, except now you can assign them to repos that actually were
    created from wild card patterns.  So for example, you can define
    rules for

        repo foo/..*

    and then assign descriptions like

        foo/repo1 = "repo one"
        foo/repo2 = "repo two"
        foo/dil "scott" = "scott's dilbert repo"

    However, this only works for repos that already exist, and only when
    you push the admin repo.

    Thumb rule: have the user create his wild repo, *then* add and push
    the admin config file with the description.  Not the other way
    around.

implementation notes:

  - wildcard support for git config revamped, refactored...

    it's not just git config that needs wildcard support.  daemon and
    gitweb access also will be needing it soon, so we start by factoring
    out the part that finds the "pattern" given a "real" repo name.

  - GL_NO_DAEMON_NO_GITWEB now gates more than just those two things;
    see doc/big-config.mkd for details

  - we trawl through $GL_REPO_BASE_ABS *once* only, collecting repo
    names and tying them to either the same name or to a wild pattern
    that the repo name was created from

  - nice little subs to setup gitweb, daemon, and git config

  - god bless $GL_REPOPATT and the day I decided to set that env var
    whenever a user hits a wild repo in any way :-)

  - the code in gl-compile-conf is very simple now.  Much nicer than
    before
2010-08-11 22:38:16 +05:30
Sitaram Chamarty 61802045d9 (mini refactor) clean up the repo_base_abs stuff
make it a sort of "super global" (an ENV var) all through, because
*everyone* seems to need it *and* this variable is pretty much constant
for the entire install
2010-08-11 22:38:16 +05:30
Kevin P. Fleming 33d052dc7d it is not an error for a wildcard repository to not match any patterns... that just means it does not have any config keys defined 2010-08-11 22:38:15 +05:30
Sitaram Chamarty d1d2c3e054 git config settings in wild repos: part 1
- 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)
2010-08-11 22:38:15 +05:30
Sitaram Chamarty c8879264e6 separate out the code that sets up ~/.ssh/authorized_keys
NOTE: there are no *functional* changes in this for *normal*
    gitolite users.  It's just a chunk of code moving into a new
    subroutine etc.

KDE needs to populate the authkeys file from an LDAP store.  Other large
projects may have similar means to store keys, depending on how they do
their user provisioning so a generic solution is worth exploring.

This means that in these special cases
  - the gitolite-admin repo's keydir/ directory is not needed [1]
  - but they still need to create the authkeys file somehow

Implementation:

  - write a shim program to make the authkeys-generation code callable
    from the command line/shell.
  - set $GL_NO_SETUP_AUTHKEYS=1 in the rc file to disable authkey
    generation during a "compile" (admin repo push)

Expected usage of new program gl-setup-authkeys:

  - LDAP change triggers some script
  - this script collects all keys from LDAP, puts them in some
    directory, and then calls gl-setup-authkeys, passing it the name of
    the directory

ALSO PLEASE SEE COMMENTS AT THE TOP OF THE NEW PROGRAM IN THIS COMMIT
FOR SOME IMPORTANT DISCUSSION.

----

Footnotes:

[1] It doesn't make sense to use it if the keys will be maintained by
some other entity and can be called up as needed, and it adds an
unnecessary extra step.

Sitaram Chamarty fbb9dafbd1 gqt -- gitolite quick (re-)test
sometimes I want to quickly test a few lines of change within the context of
a currently-running/just-ran test, *without* doing the rollback etc.

Here's how you do that now:

  - in your source tree, make the change and then run:
        cp -a src hooks contrib/adc /some/tmp/place
  - go to the tester userid and re-run your tests like so:
        GQT=/some/tmp/place ./test-driver.sh
    it'll rollback as normal then overwrite src and hooks from $GQT

Also, there's now a "dbg" sub that can be used for quick printf-style
debugging.
2010-08-09 23:21:14 +05:30
Sitaram Chamarty f0c280cd38 allow "info" to have some chance of working on big-config setups!
Fedora, till now, had no hope in hell of running the info command.  Why?
Because the output of the info command is semantically the same as the
output of the compile script *before* the big-config mode was created.

And we all know how _that_ went ;-)

So now you get to give "info" a partial reponame or a pattern, just like
in the case of "expand".  And if you're under GL_BIG_CONFIG this pattern
is mandatory.  And if you try to cheat it'll still stop after showing 5
entries to prevent (accidental?) DOSs

Anyway, see doc changes in this commit for more details.
2010-07-31 01:30:43 +05:30
Sitaram Chamarty c25e05d87b distinguish "repo not found" from "no access" if the user has rights anyway
thanks to Jesse from the Fedora team for pointing this out.  They use
GL_NO_CREATE_REPOS, so sometimes the physical repo on disk doesn't exist
at the time the config file is written.

We're talking about non-wild repos only here, so this means it should
never happen to normal gitolite users.  But now -- in the rare case that
there is a disk-side problem -- people who have rights to a repo will
get a more specific error message.
2010-07-30 09:32:38 +05:30
Jeff Mitchell 14248a3441 add '[' as allowed starting character for repo patterns
this allows the first part of the repo name (if wildcard repos are
activated) to have a regex like [a-zA-Z0-9]+.

----

Note added by committer:

he assumption used to be that all wildcard repos will have some common
prefix like "users", but I did not imagine it would be like

    repo [a-zA-Z0-9]+/users/CREATOR/[a-zA-Z0-9]+

(viz., the "users" is in the middle).

Sounds reasonable...
2010-06-22 22:00:55 +05:30
Sitaram Chamarty 98a42be614 asking for other users' perms had a bug in BIG_CONFIG mode
fixes:
  - allow "grouped" admins to get basic info for other users by checking
    more than just the *user*'s right to the admin repo
  - report_basic is called with a $user argument, but it's not easy
    (right now) to propagate this to parse_acl.  Use a simple kludge,
    (for now at least).

thanks to bcooksley for catching this
2010-06-20 00:57:21 +05:30
Sitaram Chamarty a430cc57c7 separating "push" from "create"
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>

2010-06-18 19:31:06 +05:30
Sitaram Chamarty 0f5f82e4f5 log message changes (warning: minor backward compat breakage)
The log message format has changed.  All log messages now have a common
prefix (timestamp, user, IP).  This is followed by $SSH_ORIGINAL_COMMAND
(or, in one special case, the name of the user's login shell).  Any
further text appears after this (currently this only happens in the case
of a successful push -- one for each ref pushed successfully)
2010-06-16 17:22:37 +05:30
Sitaram Chamarty ba8094d6f5 report_basic forgot how to display wildcards during big-config change
in addition, due to "+" becoming a valid character in a normal reponame,
(think gtk+, etc), the pattern

    repo dev/CREATOR/.+

doesn't look like a wildcard repo anymore, so we add an extra check that
if CREATOR is mentioned, it *is* a wildcard.

This has been added *only* to the report_basic function; it doesn't
really matter anywhere else.
2010-06-12 09:27:25 +05:30
Sitaram Chamarty 6d32e4e920 now you can disallow creation of new refs if you like
see doc/3 for details (look for "separating delete and rewind rights"

----

and for gerrit, this is one more thing it can do that we can too ;-)

[the original text was somewhat misleading.  We mean "prevent someone
from creating a branch that they have permissions to push".  That is
what is now possible, where it was not possible before.]
2010-06-02 06:47:22 +05:30
Sitaram Chamarty fd85ee2c91 *try* to make upgrades resilient to format changes (pkg maintainers please read)
the commits leading up to v1.5 caused the data format to change (we
added a rule sequence number).

This in turn caused a problem for people who may have installed using
the "system install / user setup" mode of install (which includes people
who used RPM/DEB to install it) -- they would now have to *manually* run
"gl-setup" once after the rpm/deb upgrade.

This commit *tries* to mitigate this problem by recording a data format
version number in the compiled output file.  On any access to that file,
if the version number is not found or is found to be not equal to the
current version, gl-setup is run again.

The reason I say "*tries*" is that the exact command used to do this is
a bit of a hack for now.  However, if it works for Fedora and Debian,
I'm going to leave it at that :)
2010-05-21 14:40:03 +05:30
Sitaram Chamarty 32056e0b7f (big one!) rule sequencing changes!
There were 2 problems with rule sequencing.

Eli had a use case where everyone is equal, but some are more equal than
the others ;-)  He wanted a way to say "everyone can create repos under
their own names, but only some people should be able to rewind their
branches".

Something like this would be ideal (follow the rules in sequence for
u1/u2/u3/u4, and you will see that the "deny" rule kicks in to prevent
u1/u2 from being able to rewind, although they can certainly delete
their branches):

    @private-owners = u1 u2
    @experienced-private-owners = u3 u4

    repo CREATOR/.*
      C   = @private-owners @experienced-private-owners
      RWD = CREATOR
      RW  = WRITERS
      R   = READERS
      -   = @private-owners
      RW+D = CREATOR

In normal gitolite this doesn't work because the CREATOR rules (which
get translated to "u1" at runtime) end up over-writing the "deny" rule
when u1 or u2 are the creators.  This over-writing happens directly at
the "do compiled.pm" step.

With big-config, this does not happen (because @private-owners does not
get expanded to u1 and u2), but the problem remains: the order of
picking up elements of repo_plus and user_plus is such that, again, the
RW+D wins (it appears before the "-" rule).

We fix all that by

  - making CREATOR complete to more than just the creator's name (for
    "u1", it now becomes "u1 - wild", which is actually illegal to use
    for real so there's no possibility of a name clash!)
  - maintaining a rule sequence number that is used to sort the rules
    eventually applied (this also resulted in the refex+perm hash
    becoming a list)
2010-05-18 16:36:06 +05:30
Sitaram Chamarty 8da223f92a (big-config) allow usergroup information to be passed in from outside
[Please NOTE: this is all about *user* groups, not *repo* groups]

SUMMARY: gl-auth-commmand can now take an optional list of usergroup
names after the first argument (which is the username).

See doc/big-config.mkd in the next commit or so
2010-05-14 21:44:51 +05:30
Sitaram Chamarty cf0e568c89 (big-config) the new "big-config" for large setups
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

This commit series allows an admin to designate a set of commands that

into a new one they have "C" access to:

This commit series refactors all the rights querying logic.

  - old repo_rights sub renamed to wild_repo_rights
  - new repo_rights sub to be a single entry point for most rights
    queries
      - callable from gl-auth-command and expand_wild
      - callable from *outside* too, as long as $ENV{GL_USER} is set
  - the format of the returned permissions contains C, R, and W as
    applicable, with sigils reflecting the 3 possible ways in which you
    can get R or W perms (2 ways for C):
        @R  means @all users have the same access
        #R  means you're a "super user" (think root's shell prompt) so
            you can see all repos
         R  is the normal, explicit, access
