Avoid complaining that a file with "is beyond a symbolic link" when the
filepath is absolute and the symlink in question is not actually inside the
git repository.
This assumes that inodes remain stable while the command is running.
I think they always will, the filesystems where they are unstable change
them across mounts. (If inodes were not stable, it would just complain about
symlinks in the path that are not inside the working tree.)
(On windows, I don't want to assume anything about inodes, they could be
random numbers for all I know. But if they were, this would still be ok, as
long as windows doesn't have symlinks that are detected by isSymbolicLink.
Which seems a fair bet.)
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.
Reduce the number of directories listed in libdirs, which makes the linker
check a lot less dead ends looking for directories.
Eliminated some directories that didn't really contain shared libraries,
or only contained the linker.
That left only 2, one in lib and one in usr/lib, so consolidate those two.
Doing it this way, rather than just consolidating all libs that might exist
into a single directory means that, if there are optimised versions of some
libs, eg in lib/subarch/foo.so, and lib/subarch2/foo.so, they don't get
moved around in a way that would make the linker pick the wrong one.
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.

And add a test case for that.
This certianly loses some of the 2x performance improvement in file
seeking that seekFilteredKeys led to, because now it has to stat the
worktree files again. Without benchmarking, I expect there will still be
a sizable improvement, and also the git-annex branch precaching that
seekFilteredKeys can do will still be a win of its approach.
Also worth noting that lookupKey, when the file DNE, check if it's in an
adjusted branch with hidden files, and if so, finds the key for the
file anyway. That was intended to make git-annex sync --content be able
to process those files, but a side effect was that, when a file was
deleted but the deletion not yet staged, git-annex commands used to
still list it. That was actually a bug. This commit fixes that bug too.
(git-annex sync --content on such a branch does not use seekFilteredKeys
so was not affected by the reversion or by this behavior change)

This was a bit disappointing, I was hoping for a 2x speedup. But, I think
the metadata lookup is wasting a lot of time and also needs to be made to
stream.
The changes to catObjectStreamLsTree were benchmarked to not also speed
up --all around 3% more. Seems I managed to make it polymorphic after all.
Turns out the %(rest) trick was not needed. Instead, just maintain a
list of files we've asked for, and each cat-file response is for the
next file in the list.
This actually benchmarks 25% faster than before! Very surprising, but it
must be due to needing to shove less data through the pipe, and parse
less.
This assumes that no location log files will have a newline or carriage
return in their name. catObjectStream skips any such files due to
cat-file not supporting them.
Keys have been prevented from containing newlines since 2011,
commit 480495beb4. If some old repo
had a key with a newline in it, --all will just skip processing that key.
Other things, like .git/annex/unused files certianly assume no newlines in
keys too, and AFAICR, such keys never actually worked.
Carriage return is escaped by preSanitizeKeyName since 2013. WORM keys
generated before that point could perhaps contain a CR. (URL probably not,
http probably doesn't support an URL with a raw CR in it.) So, added
a warning in fsck about such keys. Although, fsck --all will naturally
skip them, so won't be able to warn about them. Not entirely
satisfactory, but I'll bet there are not really any such keys in
existence.
Thanks to Lukey for finding this optimisation.
The cache was removed way back in 2012,
commit 3417c55189
Then I forgot I had removed it! I remember clearly multiple times when I
thought, "this reads the same data twice, but the cache will avoid that
being very expensive".
The reason it was removed was it messed up the assistant noticing when
other processes made changes. That same kind of problem has recently
been addressed when adding the optimisation to avoid reading the journal
unnecessarily.
Indeed, enableInteractiveJournalAccess is run in just the
right places, so can just piggyback on it to know when it's not safe
to use the cache.
adb shell has sha256sum sha1sum and some others, so they could be used.
They're provided by toybox, so seem about as likely to keep
working as find and stat, which it already depends on.
Or to not add a dep, could use stat the same as getExportContentIdentifier
to get a mtime, and make a WORM key. But do I really want this to
default to WORM?
Unsure what's the best path, so punting for now.
Only supported by some special remotes: directory
I need to check the rest and they're currently missing methods until I do.
git-annex sync --no-content does not yet use this to do imports
Always run Git.Config.store, so when the git config gets reloaded,
the override gets re-added to it, and changeGitRepo then calls extractGitConfig
on it and sees the annex.* settings from the override.
Remove any prior occurance of -c v and add it to the end. This way,
-c foo=1 -c foo=2 -c foo=1 will pass -c foo=1 to git, rather than -c foo=2
Note that, if git had some multiline config that got built up by
multiple -c's, this would not work still. But it never worked because
before the bug got fixed in the first place, the -c value was repeated
many times, so the multivalue thing would have been wrong. I don't think
-c can be used with multiline configs anyway, though git-config does
talk about them?
Trivial since git-annex cannot remove, but do an active checkKey verification
anyway, in case the data was lost somehow.

Made several special remotes support locking content on them while
dropping, which allows dropping from another special remote when the
content will only remain on a special remote of these types.
In both cases, verify the content is present actively, because it's
certianly possible for things other than git-annex to have removed it.
Worth thinking about what to do if at some later point, git-lfs gains
support for dropping content, and a content locking operation.
That would probably need a transition; first would need to make lockContent
use the locking operation. Then, once enough time had passed that we can
assume any git-annex operating on the git-lfs remote had that change,
git-annex could finally allow dropping from git-lfs.
Or, it could be that git-lfs gains support for dropping content, but not
locking it. In that case, it seems this commit would need to be reverted,
and then wait long enough for that git-annex to be everywhere, and only
then can git-annex safely support dropping from git-lfs.
So, the assumption made in this commit could lead to bother later.. But I
think it's actually highly unlikely git-lfs does ever support dropping;
it's outside their centralized model. Probably. :) Worth keeping in mind as
the same assumption is made about other special remotes though.

git is making that configurable, and configuring it globally would break
the test suite in a few places.
No other part of git-annex assumes any branch name. Renamed a few
placeholders to make that clearer.

Otherwise use the vendored copy as before.
The library is in Debian testing but not stable. Once it reaches
stable, the vendored copy can be removed.
Did not add it to debian/control because IIRC that's used to build
git-annex on stable too, possibly. However, the Debian maintainer will
probably want to make the package depend on libghc-http-client-restricted-dev

Fix a deadlock that could occur after git-annex got an unlocked file,
causing the command to hang indefinitely.
Known to happen on vfat filesystems, possibly others.
Note that a deadlock is still theoretically possible, if anything
smudge --clean does causes it to run the git queue for some other
reason.
Apparently that doesn't happen, but will need to keep an eye on it.
That made eg git-annex get of an unlocked file hang until the
annex.pidlocktimeout and then fail.
This fix should be fully thread safe no matter what else git-annex is
doing.
Only using runsGitAnnexChildProcess in the one place it's known to be a
problem. Could audit for all places where git-annex runs itself as a child
and add it to all of them, later.
Fix bug that made creds not be stored in git when a special remote was
initialized with gpg encryption, but without an explicit embedcreds=yes.
(Yet nother regression introduced in version 7.20200202.7. 5th so far.)
This makes the creds get saved, since only things recorded there will be
saved.
IIRC, unparsedRemoteConfig was not originally available when I
implemented this; now that it is things get a bit simpler.
More could probably be simplified, is externalConfigChanges needed at
all?
This does not entirely fix the bugs though, because creds are only
embedded when embedcreds=yes, but not when encryption=pubkey is used
without embedcreds=yes.
checkpresentkey: When no remote is specified, try all remotes, not only
ones that the location log says contain the key. This is what the
documentation has always said it did.
Still try the logged remotes first, because they are far more likely to
have the key.
