check-code: warn to use killdaemons instead of kill `cat PIDFILE`
We have a bunch of tests that still use
kill `cat hg.pid`
or worse,
kill `cat hg.pid`; while kill -0 `cat hg.pid`; sleep 0; done
Cleaning these up to use tests/killdaemons.py is non-trivial, so for now
we just add a warning.
git convert: some versions of git use fatal: instead of error:
I saw this behavior with git 1.7.12 on my Mac.
test-convert-git: stabilize corruption of test git repo
This error would show up only intermittently since the
test depended on the order of the directories returned by os.walk.
The damage repository test would delete the first object file it came
across. However, the order of the directory listing is arbitrary (it
seems to depend on the filesystem). This meant that sometimes a commit
object was deleted, sometimes a blob object and sometimes a tree
object.
So, fix by hardcoding which object to delete. Delete a commit object,
a blob object and a tree object in three separate tests.
convert/git: catch errors from modern git-ls-remote (
issue3428)
Since git v1.7.8.2-327-g926f1dd (the change was first released in git
1.7.10), git does not return non-zero when "git ls-remote --tags ..."
is run and the repository is damaged. This causes the "damaged
repository with missing commit" test in test-convert-git.t to
unexpectedly succeed.
Fix by aborting if git outputs any lines beginning with "error:",
which required adding some subprocess use in convert/git.py.
