- 79f0a5f ("(big one!) more than one wildcard may match a repo...")
makes some of the dire warnings about this irrelevant
- d1d2c3e and ad64f99 ("git config settings in wild repos: part 1" and
"...part 2") makes this caveat also useless
While we were about it, we added a quick intro and tried to make some
other details a little clearer.
for people who don't get the continual reference to towels when talking
about the "gl-dont-panic" program, all I can say is that your education
is incomplete ;-)
As usual there's more documentation than code.
Unlike usual, however, this isn't completely tested. Please read the
documentation for details of what works, what doesn't, what has been
tested, what hasn't, and so on.
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
adapted from code by kpfleming@digium.com. I basically cherry-picked
the top commit on "pu-work" (30068d1) on his fork at github, and made
some minor fixups to it
- all anchors prefixed by AUTO_ now
- some bad links fixed (maybe still a few I didn't catch)
- misc wording changes/additions (support section to README,
"technical skills" section to install doc, etc).
because someone else found the doc overwhelming. However, the suggested
reading order (which so far existed only on the wiki) was probably a
good thing to have at the top of the README, and the disclaimers about
ssh may help keep my sanity a little longer ;-)
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
jefferai pointed out that some of the links about this were broken, and
a quick look showed that it was described in multiple places too.
Brought it all together...
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!
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.
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) ;-)
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
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 :)
(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
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
