Git has an obnoxious special case in git config, a line "foo" is the same
as "foo = true". That means there is no way to examine the output of
git config and tell if it was run with --null or not, since a "foo"
in the first line could be such a boolean, or could be followed by its
value on the next line if --null were used.
So, rather than trying to do such a detection, track the style of config
at all the points where it's generated.
aeca7c2207 was predicated on the
assumption that updateTo would stage any journal files, but in one case
it did not actually do so. The test suite happened to expose the bug.
Around 3% total speedup.
Profiling git annex find --not --in web, it's now bytestring end-to-end,
and there is only a little added overhead in eg accessing the Annex
state MVar (3%). The rest of the runtime is spent reading symlinks, and
in attoparsec.
This feels like the end of the optimisation road, without a major change
like caching information for faster queries.
The only price paid is one additional MVar read per write to the journal.
Presumably writing a journal file dominiates over a MVar read time by
several orders of magnitude.
--batch does not get the speedup because then it needs to notice when
another process has made a change. Also made the assistant and other damon
modes bypass the optimisation, which would not help them anyway.
Attoparsec parser for diff-tree.
Changed fromRef back to producing a String, to avoid needing to convert
every use of it. However, this does mean I'm going to miss some
opportunities where fromRef is used and the result converted back to a
ByteString. Would be worth revisiting that at some point maybe.
After a user completely ignored the display of the exception probably
because it didn't make sense..
This does make it a little bit slower since it checks adb is in path each
time before running it. Also, it might display a lot of warnings about it
not being installed.
