Always passing "-p 22" to ssh (or "-P 22" to scp) if no custom port is given on
the command line causes trouble when not using a host name but an SSH session
name (as defined in .ssh/config) which defines a non-standard port, because the
port given on the command line overrides that port.

Having to specify "D" separately from RW or RW+ was cumbersome, and
although I don't actually use this feature, I can see the point.
One way to think of this is:
- RW and RW+ were the only existing branch level rights
- it doesnt make sense to have D rights without W (hence RW) rights
- so we simply suffix a D to these if required.
Thus you can have RW, RW+, RWD, RW+D.
I hope the (hopefully few) of you who have started to use this feature
will convert your configs when you next upgrade to "pu".
I now regret pushing the previous syntax to master too quickly -- lots
of people use master only, and on the next promotion of pu the syntax
will change. To reduce this exposure, this change will be promoted to
master very soon.
Previous implementations of "give shell access to some gitolite users"
feature were crap. There was no easy/elegant way to ensure that someone
who had repo admin access would not manage to get himself shell access.
Giving someone shell access requires that you should have shell access
in the first place, so the simplest way is to enable it from the server
side only.
So now that we decided to do that, we may as well prepare for other,
future, commands by starting a server-side utility program with
sub-commands (the only current one being "shell-add")
normally, RW+ means permission to rewind or delete.
Now, if you use "D" permission anywhere in a repo config, that means
"delete" and RW+ then means only "rewind", no delete.
All this is about a user trying to look if a repo exists or not, when he
does not have any access to that repo. Ideally, "repo does not exist"
should be indistinguishable from "you dont have perms to that repo".
(1) if $GL_WILDREPOS is not set, you either get a permissions error, or
a "$repo not found in compiled config" death. Fixed.
(2) if $GL_WILDREPOS is set, you either get either a permissions error,
or a "$repo has no matches" death. Fixed.
(3) The following combination leaks info about repo existence:
- actual repo doesn't exist
- spying user don't have C perms
- repo patt doesn't contain CREATER
- RW+ = CREATER is specified (as is normal)
In such case, the "convenience copy" of the ACL that parse_acl
makes, coupled with substituting CREATER for the invoking user means
$repos{$actual_repo} has RW+ for the spying user. This means the
access denied doesn't happen, and control passes to git, which
promptly expresses it unhappiness and angst over being given a repo
that 'does not appear to be a git repository'
This doesn't happen if all those conditions are not met:
- if repo exists, CREATER is set to the real creater, so RW+ =
CREATER does not gain spying user anything
- if spying user has C perms it just gets created, because he has
rights. This is also info leak but we can't prevent it; tighten
the config (maybe by including CREATER in repo pattern) if this
is not wanted
- if repo patt contains CREATER it will never match someone else's
repo anyway!
a configuration like this:
repo CREATER/.*
C = CREATER
RW+ = WRITERS
was buggy; CREATER was implicitly part of WRITERS so he got RW
permissions implicitly, so the push went through
what this means is that until now, everyone who used easy-install
(without needing to set $GIT_PATH in the rc file) had a client-side PATH
that was perfectly valid on the server side also!
- no need to put it at the end of the config file now, yeaaay!
- @all for @all is meaningless and not supported. People asking will
be told to get a life or use git-daemon.
- NAME/ limits for @all repos is ignored for efficiency reasons.
Data dumper was failing (returning an empty string!) on an input config
file of about 350 lines or so (output 2400 lines or so).
Removing the sort sub fixed the problem.
To recap why that sub was put in (see deleted lines in this commit for
details), what we really want is that $creater must appear *last* in the
resulting dump.
So we trick it. "man ascii" tells you that ~ is the highest valued
ASCII character (yes, I know, not utf-8 safe etc... I'll deal with that
if and when needed or punt!). So we just put that in front of $creater
and remove it later...
You *don't* want to do this for $readers and $writers -- then they will
once again sort *after* $creater, which would be a bad thing. Also,
it's probably better this way, because now the order of the hash keys
will be: $readers, $writers, any actual users listed, and then $creater.
This means the effective access rights will be:
1. if you are the creater you get CREATER's rights
2. else if your userid is listed *explicitly* in the config, you get
those rights
3. else if you've been setperm'd as a writer, you get WRITERS rights
4. else if you've been setperm'd as a reader, you get READERS rights
This is different from what used to happen till now; READERS and WRITERS
used to trump explicitly given rights. I'd been meaning to fix that
somehow, but never got around to it, until this DDD (damn Data Dumper!)
forced my hand :)
The new style personal branches work by interpreting the special
sequence /USER/ (including the slashes) in a refname. Docs should be in
the next commit...
the changes to cp/scp are because without "-p" they dont carry perms
across to existing files. So if you forgot to chmod +x your custom
hook and ran easy install, then after that you have to go to the server
side to fix the perms...
I've been unwilling to create the authkeys file if it does not already
exist, because it represents a significant change in accessibility for
that account.
However, in the "distro package" scenario, one wants to make it as easy
as possible for the end-user (who is actually an admin for the gitolite
being hosted on his account, let's not forget) to use.
And it seems that in some cases that might mean he does not (yet) have a
~/.ssh even...
when repos are copied over from elsewhere, one had to run easy install
once again to make the new (OS-copied) repo contain the proper update
hook.
We eliminate this step now, using a new, empty, "hook" as a sentinel and
having "compile" check/fix all repos' hooks.
Since you have to add the repos to conf anyway, this makes it as
seamless as possible. The correct sequence now is
- (server) copy the repo at the OS level
- (admin clone) add it to conf/gitolite.conf, commit, push
Currently the pattern of expand command is line anchored. This is
different than in e.g. grep, and causes extra work to add '.*' prefix
and/or suffix in many use cases.
The new semantics now mean you might get more matches than you would
have gotten earlier. However, the expand command is still totally
undocumented, so I think it is acceptable to change the functionality.
;)
This patch removes the anchoring. So for earlier behavior the specified
pattern needs be in form of '^<pattern>$'. The default pattern is also
changed from '.*' to '^', so there might be even a small speed
improvement. =)

stupid me; committed the easy install patch on master *and* pushed,
instead of on pu...
Since I dont want to rewind master, we end up with this completely
unnecessary merge.
let expand_list be just that "expand a list", and leave checking to be
done outside.
otherwise, commit 690604d79 has the side effect of restricting refs to
$REPOPATT_PATT, and so for instance barfing on the perfectly valid
RW+ refs/(?!heads/master) = alice bob
(thanks to Teemu for catching this)
[TODO: allow a callback for a password checking function, such as
"passwd_policy_check". Question is where the function would go.
~/.gitolite.rc is the only possible place among the current set of files
but I'd rather leave that as a list of simple name=value lines for all
sorts of reasons. So maybe something like ~/.gitolite.pm (analogous to
the "gitolite.pm" in the sources I supply), which would get "require'd"
if found, and would contain all user-defined functions like this one...
needs some thinking about]
this came up in some other discussion with bremner. As usual I said no
I won't do it because I don't see any real need.
...then I realised it's just one line :)
(about this commit)
The install doc now describes both the ways of installing gitolite.
It also has a handy appendix for package maintainers describing what
they need to do.
(about the "dps" -- distro packaging support -- commit series)
This commit is the last in the chain meant to make gitolite more
friendly for package maintainers.
Frankly, I never really thought gitolite would get big enough or
important enough for someone to package it, and I always did just
the bare minimum I needed to get it working, first for myself, then
anyone who hopped onto #git and asked. As a result, it had some
quirks in terms of what is expected where and so on...
Luckily, it didn't take a lot of changes to fix it, and this series
of commits should help make it very easy to package gitolite for
system-wide use.
The old install method will now use conf/VERSION instead of src/VERSION everywhere.
The new one, if you use the builtin make file to "make branch.tar" will also create just such a file
gl-install copies
- the initial rc file to ~/.gitolite.rc if it doesn't exist
- src and hooks to GL_ADMINDIR
Make it aware of a package-based setup sequence, where the above two
change somewhat; see code diff.
This should be the last bit of change needed to prepare gitolite setup
so that a distro package maintainer does not have to fiddle too much
with code inside.
(What remains is docs, and a setup script for server-side use, to
replace the latter part of easy install)
