(manually tested)
- new rc var: GL_BINDIR2; see doc update in this commit
- added _which() function to search both $GL_BINDIR and $GL_BINDIR2
- 'gitolite <command>', non-perl triggers, VREFs, and sugar, use this
- unshifted $GL_BINDIR2/lib into @INC upfront in Rc.pm
- perl triggers use this
Although this is not a "hole" that allows a normal user to bypass
controls, I still consider this a hole in the sense that I want to
separate "admin push" rights from "shell access on server" rights.
(I realise that most people don't make this distinction, but I do, and
for me and most sites I consult for it is important).
Thanks to drue on #gitolite who pointed it out excitedly, and apologies
for killing what he thought of as a feature!
Using a g2-style "chained update hook" as a VREF doesn't *quite* work:
- all STDOUT from the hook is lost
- worse, all lines get parsed as a ref followed by a message, and if
the ref doesn't look like a ref it dies
So now we do all this only if the message starts with 'VREF/'. Any
other output is just printed out as is.
