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.

When I put in Haskell98 this spring, I was under the mistaken
apprehension that ghc defaulted to that. But it actually its default
is a third mode, which is closer to Haskell2010 but with some differences.
The manual says "By default, GHC mainly aims to behave (mostly) like a
Haskell 2010 compiler"
Fixed two cases where the Haskell98 do indentation flexability let
wrongly indented code build. That is one of the places where
ghc does not behave like Haskell2010 by default.
The other place that I think I was concerned about, is GHC manual
section 19.1.1.3. Expressions and patterns. But that only seems to
affect code using bottoms, so would only affect pure functions throwing
an error, which I don't think git-annex does in many places as it's
pretty horrid style. And it would only affect rare cases like shown in
that section. If it did happen, it would mean that the error was not
thrown before specifying Haskell98, and then was. Haskell2010 behaves
the same as Haskell98.

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.
sync: When run without --content, import without copying from
importtree=yes directory special remotes. (Other special remotes may
support this later as well.)
This commit was sponsored by Svenne Krap on Patreon.
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.

The latter is for git-annex matchexpression and matching against it can
throw an exception. Splitting out the former reduces the potential for
mistakes and avoids needing to worry about matching against that
throwing an exception.
This is more groundwork for matching largefiles while importing,
without downloading content.
This commit was sponsored by Graham Spencer on Patreon.
Anything that needs to examine the file content will fail to match,
or fall back to other available information. But the intent is that the
matcher be checked for matchNeedsFileContent and only be used if it does
not, so the exact behavior doesn't much matter as it should never
happen.
The real point of this is to not need to provide a dummy content file
when matching.

This was the last one marked as a zombie. There might be others I don't
know about, but except for in the hypothetical case of a thread dying
due to an async exception before it can wait on a process it started, I
don't know of any.
It would probably be safe to remove the reapZombies now, but let's wait
and so that in its own commit in case it turns out to cause problems.

Eliminate a zombie that was only cleaned up by the later zombie cleanup
code.
This is still not ideal, it would be cleaner if it used conduit or
something, and if the thread gets killed before waiting, it won't stop
the process.
Only remaining zombies are in CmdLine.Seek
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.

Otherwise the bloom filter may not be fully populated when the second
pass starts, which could have led to incorrect behavior with --all -J,
probably in very rare circumstances.
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.

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.
The use case of this field is mostly to support -J combined with --json.
When that is implemented, a user will be able to look at the field to
determine which of the requests they have sent it corresponds to.
The field typically has a single value in its list, but in some cases
mutliple values (eg 2 command-line params) are combined together and the
list will have more.
Note that json parsing was already non-strict, so old git-annex metadata
--json --batch can be fed json produced by the new git-annex and will
not stumble over the new field.
No behavior changes (hopefully), just adding SeekInput and plumbing it
through to the JSON display code for later use.
Over the course of 2 grueling days.
withFilesNotInGit reimplemented in terms of seekHelper
should be the only possible behavior change. It seems to test as
behaving the same.
Note that seekHelper dummies up the SeekInput in the case where
segmentPaths' gives up on sorting the expanded paths because there are
too many input paths. When SeekInput later gets exposed as a json field,
that will result in it being a little bit wrong in the case where
100 or more paths are passed to a git-annex command. I think this is a
subtle enough problem to not matter. If it does turn out to be a
problem, fixing it would require splitting up the input
parameters into groups of < 100, which would make git ls-files run
perhaps more than is necessary. May want to revisit this, because that
fix seems fairly low-impact.
Make all calls to git merge go through autoMergeFrom, in preparation

Fixes reversion in 8.20200617 that made annex.pidlock being enabled result
in some commands stalling, particularly those needing to autoinit.
Renamed runsGitAnnexChildProcess to make clearer where it should be
used.
Arguably, it would be better to have a way to make any process git-annex
runs have the env var set. But then it would need to take the pid lock
when running any and all processes, and that would be a problem when
git-annex runs two processes concurrently. So, I'm left doing it ad-hoc
in places where git-annex really does run a child process, directly
or indirectly via a particular git command.
addurl: Fix reversion in 7.20190322 that made --file not be honored when
youtube-dl was used to download media.
8758f9c561 was on the right track, but missed that | otherwise prevented
the code it added from being used.
Also, refactored out a common function.

Part of workTreeItems is trying detect a case
where git porcelain refuses to process a file, and where
git ls-files silently outputs nothing. But, it's hard to perfectly
replicate git's behavior, and besides, git's behavior could change.
So it could be that we warn, but then git ls-files does not skip over
it, and so git-annex also processes it after warning about it.
So, if we think we have a problem with a parameter, display the warning,
and skip processing it at all.
Implementing this was complicated by needing to handle the case where
all command-line parameters get filtered out this way. Which is
different than the case where there are none, because we don't want to
operate on all files in this new case..
sanitizeFilePath was changed to sanitize leading '.', but ImportFeed was
running it on parts of the template. So eg the leading '.' in the extension
got sanitized.
Note the added case for sanitizeLeadingFilePathCharacter ('/':_)
-- this was added because, if the template is title/episode and the title
is not set, it would expand to "/episode". So this is another potential
security fix.
This was already prevented in other ways, but as seen in commit
c30fd24d91, those were a bit fragile.
And I'm not sure races were avoided in every case before. At least a
race between two separate git-annex processes, dropping the same
content, seemed possible.
This way, if locking fails, and the content is not present, it will
always do the right thing. Also, it avoids the overhead of an unncessary
inAnnex check for every file.
This commit was sponsored by Denis Dzyubenko on Patreon.
The test suite noticed this case, where two files with the same key are
dropped, and the seek stage sees both have content due to the way files
stream through it. But then locking the content to drop fails on the
second file, because the first file has already been dropped.
So, add back otherwise redundant inAnnex check.
Sped up seeking files to drop by 2x, and also some performance
improvements to checking numcopies.
Interestingly, the seek speedup is not due to precaching, but I think is
due to calling getParsed earlier.
Annex.Drop had to be changed to check inAnnex there, since it was removed
from Command.Drop. All other users of Command.Drop already checked inAnnex
themselves.

This is groundwork for external backends, but also makes sense to keep
this information with the rest of a Backend's implementation.
Also, removed isVerifiable. I noticed that the same information is
encoded by whether a Backend implements verifyKeyContent or not.
