The crash turned out to be caused by the sqlite database being deleted out
from under sqlite before it was done with it. Since multiple git_annex
calls are done in the same process while running the test suite, the
DbHandle could linger until GCed, and the test repo, and thus sqlite
database be deleted before the workerThread was done.
The homomorphs are back, just encoded such that it doesn't crash in LANG=C
However, I noticed a bug in the old escaping; [pseudoSlash] was escaped the
same as ['/','/']. Fixed by using '%' to escape pseudoSlash. Which requires
doubling '%' to escape it, but that's already done in the escaping of
worktree filenames in a view, so is probably ok.
Linking the file to the tmp dir was not necessary in the clean
filter, and it caused the ctime to change, which caused git to think
the file was changed. This caused git status to get slow as it kept
re-cleaning unchanged files.
Fixes a minor fd leak, never more than 1 in normal use,
which broke the test suite when I tried to write to
a file that was still open for a previous hashing.
03cb2c8ece put a cat-file into the fast
bloomfilter generation path. Instead, add another bloom filter which diffs
from the work tree to the index.
Also, pull the sha of the changed object out of the diffs, and cat that
object directly, rather than indirecting through the filename.
Finally, removed some hacks that are unncessary thanks to the worktree to
index diff.
So, we need to look at both the file on disk to see if it's a annex link,
and the file in the index too. lookupFile doesn't look in the index if the file
is not present on disk.
have to change the content of unlocked file before committing
otherwise git commit will fail in v6 mode when the file was already
unlocked, because no changes have been made
