The script to install dependencies has two separate entries for 32-bit
and 64-bit Ubuntu systems. This increases the maintenance burden since
both should need roughly the same packages.
That hasn't been too bad so far because we've stayed on the same 32-bit
image since 2017. Trying to move to a newer image revealed several
problems with the linux32 job:
- newer images complain about using "linux32 --32bit i386", due to
seccomp restrictions. We can loosen these with a docker option, but
I don't think running it is even doing anything. We use it only for
pretending to "apt" that we're on a 32-bit machine, but inside the
container image apt is already configured as a 32-bit system (even
though the kernel outside the container is obviously 64-bit). Using
the same apt invocation for both architectures just gets rid of this
call entirely.
- we set DEBIAN_FRONTEND to avoid hanging on packages that ask the
user questions. This wasn't a problem on the old image, but it is on
newer ones. The 64-bit stanza handles this already.
As a bonus, the 64-bit stanza uses "apt -q" instead of redirecting
output to /dev/null. This would have saved me a lot of debugging
time trying to figure out why it was hanging. :)
- the old image seems to have zlib-dev installed by default, but newer
ones do not.
In addition, there were probably many tests being skipped on the 32-bit
build because we didn't have support packages installed (e.g., gpg). Now
we'll run them.
We do need to keep some parts split off just for 64-bit systems: our p4
and lfs installs reference x86_64/amd64 binaries. The downloaded jgit
should work in theory, since it's just a jar file embedded in a shell
script that relies on the system java. But the system java in our image
is too old, so I've left it as 64-bit only for now.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.
Git is an Open Source project covered by the GNU General Public
License version 2 (some parts of it are under different licenses,
compatible with the GPLv2). It was originally written by Linus
Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/
including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
Issues which are security relevant should be disclosed privately to
the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that
list the current status of various development topics to the mailing
list. The discussion following them give a good reference for
project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very
first version. He described the tool as "the stupid content tracker"
and the name as (depending on your mood):
random three-letter combination that is pronounceable, and not
actually used by any common UNIX command. The fact that it is a
mispronunciation of "get" may or may not be relevant.
stupid. contemptible and despicable. simple. Take your pick from the
dictionary of slang.
"global information tracker": you're in a good mood, and it actually
works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
