Without this, complex mirroring scenarios will be unpredictable. For
example (abbreviating "gitolite.mirror." to "gimo.") something as simple
as this will not give "foo" his different mirror setup
repo @all
config gimo.master = "frodo"
config gimo.slaves = "sam"
repo foo
config gimo.master = "sam"
config gimo.slaves = "frodo gollum"
repo foo bar
RW = u1
Even worse things happen when you have wild cards.
Now, however, they all come in the right sequence and the most recent
one takes effect (unlike ACL rules, where the first match wins, because
there you're trying to just find a match and get out, while here you're
just mindlessly applying config lines in the right order).
- caution about wild repos needing to be manually created on the
receiving side (because nothing gets auto-created now)
- caution about the right and wrong way to "delete" a config variable
- a few other minor fixes
We previously said all mirroring features are disabled if GL_HOSTNAME is
not set.
But what if, after mirroring has been setup, and master/slaves defined
for a repo, a slave admin fat-fingers the RC file and accidentally
comments out GL_HOSTNAME? We might end up violating RULE NUMBER ONE!
- post-receive now just calls mirror-push
- mirror-push is a medium complex shell script (all that backgrounding
etc., can't be done so easily in God's first language!)
- mirror-shell is now a perl program that does a few different things
(receive mirror-pushes, command line re-sync, re-sync requests from a
slave, etc)
- auth-command changes to reject/redirect non-native pushes
to my eternal shame (considering how proud I am of my documentation)
this was not mentioned anywhere! I'm getting old...
thanks to Pierre Habouzit for catching this
(also slipped in a few other minor doc changes. I wouldn't mix
unrelated stuff in a commit when doing code changes but it seems ok to
do this for docfixes, for some reason).
"gitolite-without-ssh" doc name was misleading; rename to
"authentication-vs-authorisation"
also restructure the whole thing to answer the main question better, and
fix up links from other places
Supporting git on DOS may be a fact of life, but it felt good to make
them use the "right" editor (hint: starts with v, ends with m, has three
letters), or at least something equivalent, to produce their setperms
input files.
I'd say "yes Fred I know. However, Unix doesn't work like that, and
when talking to a big, important, OS like Unix from your little
single-user workstation, you do have to go the extra mile. It's not
that different from going into a meeting with the CEO you know -- you
dress up a little for that meeting don't you?". And Fred would nod, a
little awed by the analogy. Maybe the awe was tinged with a wee bit of
anger but not much; he knows there's a hierarchy among OSs, just like
among people, and he knows where his OS stands in that hierarchy...
----
For the humour impaired, that was a joke. To start with, I don't know
anyone called Fred.
It *is* true that I tend to ignore DOS if at all possible, especially in
my *code*. But since I don't really use wildrepos at work, this issue
would never have come up for me, even in the DOS projects I manage.
In this case someone who's contributed a heck of a lot to the evolution
of gitolite asked, so here it is.
----
oh and in case you were wondering, DOS stands for "dominant operating
system" ;-)
otherwise repo names containing "@" in them were causing the @foo part
to be interpolated (as empty of course) instead of being taken literally
reported by silvio dot fricke at googlemail
(and in one other place it needs to be defined earlier)
I never caught this because in my testing those error conditions --
caused by lack of afc3a06 -- never came up.
Fix a problem with authkeys perms when REPO_UMASK is too loose.
(To duplicate it, run a fresh, non-root install, and when gl-setup pops
up an editor, change the REPO_UMASK to 0007 (from the default 0077).
You'll find that ~/.ssh/authorized_keys now has g+w set, causing sshd to
refuse key-based access.)
And before you ask, even though gl-setup does it, I won't fiddle with
the permissions of an existing file in *this* code. (gl-setup is run
manually by the admin, this one gets run on every push).
----
Side note: 9ad7ea4 was somewhat forced on me, and I didn't really agree
with parts of it. I have no idea why I gave in so easily, but it won't
happen again!
a warn/die may happen even before setup_environment() has been called,
so then log_it() tries to use uninitialised variables and it then adds
to the confusion complaining about *those*
I'd originally written some minimal documentation for this ADC, but I
liked Jeff's version so much that I borrowed it, added the final section
("important notes for the admin"), made a few other minor fixups, and
then happily ditched my version.
(the ones that require GL_BYPASS_UPDATE_HOOK to be set are done slightly
differently because I just didn't want all the hassle of saving and
restoring that variable on the perl side)
