Only done in checkPresentChunks, although retrieveChunks could also do
it. Does not seem necessary though, because git-annex never retrives
content without first checking if it's present AFAICR. And really this will
only be needed when using fsck. Puttting it here, rather than in fsck
avoids breaking an abstraction boundary, and is nice and inexpensive.
When a special remote has chunking enabled, but no chunk sizes are
recorded (or the recorded ones are not found), speculatively try chunks
using the configured chunk size.
This makes eg, git-annex fsck --from remote be able to fix up the
location log of a file that the git-annex branch does not indicate is
stored on the remote.
Note that fsck does *not* fix up the chunk log to indicate the chunk
size. So, changing the chunk config of the remote after that will still
prevent accessing the chunks stored on it. Maybe fsck should, but I
wanted to start with this and see if it's needed.
In cases where numcopies checks prevented the resumed move from dropping
the object from the source repository, it now relies on a log of recent
moves to replicate the behavior of the interrupted command.
Performance: Probably noticable impact, since it has to add to the log,
check the log, and remove from the log. Seems worth it to avoid this
annoying edge case. The log functions are pretty well optimised to avoid
unncessary work.
An performance improvement to make later would be to avoid cleanup doing
anything if it's not written to the log file, and has confirmed that the
log file does not contain the log line.

The problem was this line:
cleanup = and <$> sequence (map snd v)
That caused all of v to be held onto until the end, when the cleanup action
was run.
I could not seem to find a bang pattern that avoided the leak, so I
resorted to a IORef, rather clunky, but not a performance problem because
it will only be written once per git ls-files, so typically just 1 time.

inet_addr was removed, but all this needs is localhost, so hardcoding it
should work fine.
It may be that this windows ifdef is no longer needed. It was added in 2013
with a note that getAddrInfo didn't work on windows, but it seems likely
such a problem would have been fixed since.
This avoids the possibility that the bundle could be updated in place,
leading to LOCPATH existing but containing locales for the old version,
which needed to be tested for with code that was not race-free.
LOCPATH/buildid is still written and checked when cleaning up stale caches.
That is not actually necessary, except old versions of the standalone
bundle expect to see it, and this prevents them cleaning up the locale
cache of a new version. And still checking it prevents the new version
cleaning up the locale cache of the old version while the old version is
still in use.
Added explicit tests before creating LOCPATH and the base and buildid files.
The buildid file no longer needs to be updated every time, because it's
stable for the given LOCPATH directory.
And the base file actually did not need to be updated every time,
because the LOCPATH is derived from base, so if the bundle is moved
elsewhere, a different LOCPATH will be used.
Transitioning to this will mean that two git-annex builds that otherwise
have the same buildid -- the same git-annex md5sum -- will use different
LOCPATH values, but that's handled fine by the cache cleanup code, so at
most it will mean one extra generation of the locale files.
It seemed best to do this, for consistency with every other way files can
get into a git-annex repo. Although it's just a bit strange that a local
.gitignore file affects the pseudo-commits made for the remote that's
imported from.

Ensure that checkCanAdd is used everywhere a file is added to git,
so git add is run with -f, presumably avoiding the work it would usually
do to check ignores.
This avoids import with --no-content and with --content potentially
generating two different trees, leading to a merge conflict when run in
two different clones of a repo. And it's necessary groundwork to make
git-annex sync --no-content import from special remotes that support
importKey.
Only the directory special remote currently supports importKey, and it
generates the same key as git-annex usually does, so there is no
behavior change for it.
Future special remotes will need to take care when adding importKey,
if it generates different keys. Added some warnings about that to
comments.

Import small files into git, the same as is done when importing with content.
Which means, for small files, --no-content does download them.
If the largefiles expression needs the file content available
(due to mimetype or mimeencoding being used), the import will fail.

Sped up seeking for files to operate on, when using options like --copies
or --in, by around 20%.
Benchmark showed an increase for --copies from 155 seconds to 121
seconds, and --in remote will be similar to that.
For --in here, the speedup was less, 5-10% or so.

Sped up seeking to around twice as fast, by avoiding a pass over the
worktree files when preferred content expressions of the local repo and
remotes don't use include=/exclude=.
Thanks to Lukey for identifying the optimisation.

matchNeedsFileContent is not used yet, but shows how to add information
about terminals. That one would be needed for
https://git-annex.branchable.com/todo/sync_fast_import/
Note the tricky bit in Annex.FileMatcher.call where it folds over the
included matcher to propagate the information.

getPid returns Nothing if the process has already been stopped, and in that
case, the pid will not be displayed. I think that would only happen if
waitForProcess or similar gets called more than once on the same process
handle though.
getPid on unix has an overhead of only a MVar read. On Windows it needs to
make a syscall, so will be probably more expensive. While the added expense
happens even when debug logging is disabled, it should be small enough
compared with the overhead of starting a process that it's not a problem.
(It does occur to me that a debugM that took an IO String could only run it
when debugging is really enabled, which would improve performance. It does
not seem possible to use the current hslogger interface to do that though;
it does not expose the information that would be needed.)
With some hints for the user for what to do.
Took care to avoid changing the json output. It would have been ok to add
the new separated lists to it, in addition to the old list, but I didn't
do that because I didn't see much point.
add, addurl, importfeed, import: Added --no-check-gitignore option
for finer grained control than using --force.
(--force is used for too many different things, and at least one
of these also uses it for something else. I would like to reduce
--force's footprint until it only forces drops or a few other data
losses. For now, --force still disables checking ignores too.)
addunused: Don't check .gitignores when adding files. This is a behavior
change, but I justify it by analogy with git add of a gitignored file
adding it, asking to add all unused files back should add them all back,
not skip some. The old behavior was surprising.
In Command.Lock and Command.ReKey, CheckGitIgnore False does not change
behavior, it only makes explicit what is done. Since these commands are run
on annexed files, the file is already checked into git, so git add won't
check ignores.
--batch combined with -J now runs batch requests concurrently for many
commands. Before, the combination was accepted, but did not enable
concurrency. Since the output of batch requests can be in any order, --json
with the new "input" field is recommended to be used, to determine which
batch request each response corresponds to.
If --json is not used, batch mode still runs concurrently, using the usual
concurrent-output. That will not be very useful for most batch mode users,
probably, but who knows.
If a program was using --batch -J before, and was parsing non-json output,
this could break it. But, it was relying on git-annex not supporting
concurrency despite it being enabled, so it should have expected concurrent
output. So, I think that's ok.
annex.jobs does not enable concurrency in --batch mode, because that would
confuse programs that use --batch but don't expect concurrency.
So these special remotes are always supported.
IIRC these build flags were added because the dep chains were a bit too
long, or perhaps because the libraries were not available in Debian stable,
or something like that. That was long ago, those reasons no longer apply,
and users get confused when builtin special remotes are not available, so
it seems best to remove the build flags now.
If this does cause a problem it can be reverted of course..

Works better with automatic merge conflict resolution than git's ususual
default of "conflict".
This is not done when automatic merge conflict resolution is disabled.

This case was handled by cleanConflictCruft, but only when the annexed
file's object was present. When not present, it left the annexed file
with the original name, not checked into git, while adding the variant
file. So, add an explicit deletion of the deleted file in this case.
My specific case where this happened actually involves
merge.directoryRenames=conflict. After a merge involving that,
the situation was the file appears as "added by them", because that
caused the file that they added to be moved into a directory we renamed.
That case is the same as them adding a modified version of the file,
while we deleted it. (Except for the history of the file, since it's a
new file, but this doesn't look at history.)

This does not actually change how the merge conflict is resolved when
one side deleted the file, but it was not documented before, and I think
it only worked by accident.
