compile/install of git

Bruce Momjian <bruce@momjian.us> — 2010-09-17T21:02:30Z

FYI, I have compiled/installed git 1.7.3.rc2 on my BSD/OS 4.3.1 machine
with the attached minor changes.

I thought you were replacing that old thing with pile of hardware that
Matthew was putting together?

Matthew was busy this summer so I am going to try to get some of his
time by January to switch to Ubuntu.  And some people are complaining we
will lose a BSD test machine once I switch.

Test machines belong in the buildfarm. And why would they complain about 
losing a machine running a totally out of date and unsupported OS? Maybe 
you should run BeOS instead.

Well, I can run tests for folks before they apply a patch and "red" the
build farm.  I can also research fixes easier because I am using the OS,
rather than running blind tests.  I am just telling you what people told
me.

My big point in posting was to say that compiling git was not the
nightmare I expected it to be.  I figured it would want tons of newer or
odd libraries I didn't have, but that was not the case at all.  I am
sure others will need to compile git themselves for odd operating
systems, and I wanted to encourage them to try.

So?  People are still going to want to git-ify their buildfarm critters.

FWIW, I've also successfully installed git on my old HPUX box.
I avoided most of the library dependencies by giving up support for
http: URLs for repositories.  I figure git: and ssh: should cover
what I need to do with it.

For anyone else trying to get it installed on an odd platform:
their configure script improved quite a lot in the last six months,
so get a recent version.  I had to do a lot of hacking to get 1.7.1
to build, but 1.7.2.3 fixes most of those problems.  It still misses
a few things, but you can probably fix any problems by adjusting the
config.mak.autogen file afterwards.

Right. I was just reacting to Bruce's observation about what people said 
about his moving off BSD/OS.

Yeah. Git over HTTP is horribly inefficient anyway - it's really a last 
resort.

Every time I've tried to use it, it's been dog slow.  But what do I know?

That's about talking over HTTP to a git server running as CGI; it
doesn't help if you're talking HTTP to just a plain HTTP host.

I've been slowly trying to rebuild something that was in use at the
OSDL to test patches.  I just proofed something that I think works
with the git repository:

http://207.173.203.223:5000/patch/show/48

If you click on the PASS or FAIL text, it will display the SHA1,
author and commit message that the patch was applied to.  Think this
will be useful?

Seems interesting. You might need to take precautions against someone
uploading a trojan, though.

The issue has always been how much we want to ask people to trust code 
that is not committed. My answer is "not at all." Reviewers and 
committers will presumably eyeball the code before trying to compile/run 
it, but any automated system of code testing for uncommitted code is way 
too risky, IMNSHO.

I was hoping this would be more of a reviewing tool, not something
that would be an excuse for someone to not try running with a patch.
For example, if patch doesn't apply, configure, or build the output is
captured and can be referenced.  Also specifically in Bruce's example
if there is enough concern about making the buildfarm red I thought
this could help in these few specific aspects.  But maybe I don't
understand the scope of testing Bruce is referring to. :)

Mark

The whole point of the buildfarm is to identify quickly any 
platform-dependent problems. Committers can't be expected to have access 
to the whole range of platforms we support, so as long as they make sure 
that things are working well on their systems they should be able to 
rely on the buildfarm to cover the others. But that also means that the 
buildfarm should contain instances of all the supported platforms. I 
don't think we should be afraid of sending the buildfarm red. If we do 
it's an indication that it's doing its job. If you're a committer and 
you haven't made it go red a few times you're either very lucky or not 
very active. Making it go red isn't a problem. Leaving it red is, but 
we've really been pretty darn good about that.

Having someone act in effect as an informal buildfarm member is less 
than satisfactory, IMNSHO. For one thing, it is likely to be less timely 
about notifying us of problems than the automated system. And it's also 
much less likely to catch problems on the back branches. So if you want 
platform X supported (even BSD/OS, regardless of the fact that it's way 
out of date), the first thing you should do is set up a buildfarm member 
for it.

cheers
