deal with .git pointer file in Git.CurrentRepo
This fixes the bug.

Note, it's only done when GIT_DIR is set. When it's not set,
Git.Construct already handled it. This is why it was only noticed with this
git submodule command.

speculatively use remote's configured chunk size as a fallback
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.

move: Improve resuming a move that was interrupted after the object was transferred
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.

Fix a memory leak introduced in the last release
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.

Fix build on Windows with network-3
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.

import: Check gitignores when importing trees from special remotes
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.

seek: defer matcher check until more info is known
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.

Improve --debug output to show pid of processes that are started and stopped
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.)

Added --no-check-gitignore option for finer grained control than using --force.
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.

877ef84a1b
support --batch -J
--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.

add "input" field to json output
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.

add SeekInput (not yet used)
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.

Removed the S3 and WebDAV build flags
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..

resolvemerge: Improve cleanup of files that were deleted by one side of a conflicted merge, and modified by the other side
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.)

add gitAnnexChildProcess and use instead of incorrect use of runsGitAnnexChildProcess
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.

stop symlink check once the top of the working tree is reached
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.)

Slightly sped up the linux standalone bundle
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.

fix reversion in skipping deleted files
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.

make catObjectStream support newline and carriage return in filenames
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.

sped up the --all option by 2x to 16x by using git cat-file --buffer
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.

add back git-annex branch read cache
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.

no importKey for android yet
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.

refix bug in a better way
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?

lockContent for S3 (with versioning=yes) and git-lfs
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.

async exception safety for external special remote processes
Since an external process can be in the middle of some operation when an
async exception is received, it has to be shut down then. Using
cleanupProcess will close its IO handles and send it a SIGTERM.

If a special remote choses to catch SIGTERM, it's fine for it to do some
cleanup then, but until it finishes, git-annex will be blocked waiting
for it. If a special remote blocked SIGTERM, it would cause a hang.
Mentioned in docs.

Also, in passing, fixed a FD leak, it was not closing the error handle
when shutting down the external. In practice that didn't matter before because
it was only run when git-annex was itself shutting down, but now that it
can run on exception, it would have been a problem.

line.

Significant complexity was needed to handle git-annex add, which uses some
git ls-files calls, but needs to not use --error-unmatch because of course
the files are not known to git.

annex.skipunknown is planned to change to default to false in a
git-annex release in early 2022. There's a todo for that.

auto-init autoenable=yes
Try to enable special remotes configured with autoenable=yes when git-annex
auto-initialization happens in a new clone of an existing repo. Previously,
git-annex init had to be explicitly run to enable them. That was a bit of a
wart of a special case for users to need to keep in mind.

Special remotes cannot display anything when autoenabled this way, to avoid
interfering with the output of git-annex query commands.

Any error messages will be hidden, and if it fails, nothing is displayed.
The user will realize the remote isn't enable when they try to use it,
and can run git-annex init manually then to try the autoenable again and
see what failed.

That seems like a reasonable approach, and it's less complicated than
communicating something across a pipe in order to display it as a side
message. Other reason not to do that is that, if the first command the
user runs is one like git-annex find that has machine readable output,
any message about autoenable failing would need to not be displayed anyway.
So better to not display a failure message ever, for consistency.

(Had to split out Remote.List.Util to avoid an import cycle.)

disable buggy concurrency in Command.Export
Fix a crash or potentially not all files being exported when sync -J
--content is used with an export remote.

Crash as described in fixed bug report.

waitForAllRunningCommandActions inserted in several points where all the
commandActions started before need to have finished before moving on to
the next stage of the export. A race across those points could have
maybe resulted in not all files being exported, or a wrong tree being
export.

For example, changeExport starting up an action like
a rename of A to B. Then, with that action still running, fillExport
uploading a new A, *before* the rename occurred. That race seems
unlikely to have happened. There are some other ones that this also
fixes.

transferStages was confusingly named, it's only useful when doing downloads

For commands that upload, there will be more concurrency from running

As for sync, I left it using downloadStages although that's not optimal

fix embedcreds=yes reversion
Fix bug that made enableremote of S3 and webdav remotes, that have
embedcreds=yes, fail to set up the embedded creds, so accessing the remotes
failed.

(Regression introduced in version 7.20200202.7 in when reworking all the
remote configs to be parsed.)

Root problem is that parseEncryptionConfig excludes all other config keys
except encryption ones, so it is then unable to find the
credPairRemoteField. And since that field is not required to be
present, it proceeds as if it's not, rather than failing in any visible
way.

This causes it to not find any creds, and so it does not cache
them. When when the S3 remote tries to make a S3 connection, it finds no
creds, so assumes it's being used in no-creds mode, and tries to find a
public url. With no public url available, it fails, but the failure doesn't
say a lack of creds is the problem.

Fix is to provide setRemoteCredPair with a ParsedRemoteConfig, so the full
set of configs of the remote can be parsed. A bit annoying to need to
parse the remote config before the full config (as returned by
setRemoteCredPair) is available, but this avoids the problem.

I assume webdav also had the problem by inspection, but didn't try to
reproduce it with it.

Also, getRemoteCredPair used getRemoteConfigValue to get a ProposedAccepted
String, but that does not seem right. Now that it runs that code, it
crashed saying it had just a String.

Remotes that have already been enableremoted, and so lack the cached creds
file will work after this fix, because getRemoteCredPair will extract
the creds from the remote config, writing the missing file.

This relicates git's behavior. It adds a few stat calls for the command
line parameters, so there is some minor slowdown, but even with thousands
of parameters it will not be very noticable, and git does the same statting
in similar circumstances.

Note that this does not prevent eg "git annex add symlink"; the symlink
will be added to git as usual. And "git annex find symlink" will silently
list nothing as well. It's only "symlink/foo" or "subdir/symlink/foo" that
triggers the warning.

addurl --preserve-filename and a few related changes
* addurl --preserve-filename: New option, uses server-provided filename
  without any sanitization, but with some security checking.

  Not yet implemented for remotes other than the web.

* addurl, importfeed: Avoid adding filenames with leading '.', instead
  it will be replaced with '_'.

  This might be considered a security fix, but a CVE seems unwattanted.
  It was possible for addurl to create a dotfile, which could change
  behavior of some program. It was also possible for a web server to say
  the file name was ".git" or "foo/.git". That would not overrwrite the
  .git directory, but would cause addurl to fail; of course git won't
  add "foo/.git".

sanitizeFilePath is too opinionated to remain in Utility, so moved it.

The changes to mkSafeFilePath are because it used sanitizeFilePath.
In particular:

	isDrive will never succeed, because "c:" gets munged to "c_"
	".." gets sanitized now
	".git" gets sanitized now
	It will never be null, because sanitizeFilePath keeps the length
	the same, and splitDirectories never returns a null path.

Also, on the off chance a web server suggests a filename of "",
ignore that, rather than trying to save to such a filename, which would
fail in some way.

only check --force at init time, not enable time
git-lfs repos that encrypt the annexed content but not the git repo only
need --force passed to initremote, allow enableremote and autoenable of
such remotes without forcing again.

Needing --force again particularly made autoenable of such a repo not work.
And once such a repo has been set up, it seems a second --force when
enabling it elsewhere has little added value. It does tell the user about
the possibly insecure configuration, but if the git repo has already been
pushed to that remote in the clear, data has already been exposed. The goal
of that --force was not to prevent every situation where such an exposure
can happen -- anyone who sets up a public git repo and pushes to it will
expose things similarly and git-annex is not involved. Instead, the purpose
of the --force is to point out to the user that they're asking for a
configuration where encryption is inconsistently applied.

S3: Support signature=v4
To use S3 Signature Version 4. Some S3 services seem to require v4, while
others may only support v2, which remains the default.

I'm also not sure if v4 works correctly in all cases, there is this
upstream bug report: https://github.com/aristidb/aws/issues/262
I've only tested it against the default S3 endpoint.

sync: Avoid an ugly error message when nothing has been committed to master yet and there is a synced master branch to merge from
Now the warning gets displayed, which is better than an arcane git error.

The warning is still kind of ugly, especially when the pull later in the
sync will clear up what it warns about. But, this is an unusual situation
not likely to happen, and if there is no remote to pull from, the warning
message is needed or the sync will seem to succeed despite not merging the
synced master branch.

Would still be better if it could merge the synced master branch in this
situation, making an empty commit to master to do it seems wrong, and
otherwise it would need a whole separate code path, and would bypass using
git merge in favor of say, setting master to the syned branch. Which would
bypass git configs like arguably merge.ff and certianly
merge.verifySignatures. So don't want to do that.

repair: Improve fetching from a remote with an url in host:path format.
User reported git@my.gitlab.foo:username/myrepo.git didn't work with
git-repair, because it rewrites it to an url
ssh://git@my.gitlab.foo/~/username/myrepo.git
and the /~/ was not something the hosting site supported.

Since git-annex still generally needs the repo url to be well, an url, did
not change the conversion code. But in this case, we're running git fetch,
so we might as well pass it the remote name rather than the url.

Did a quick audit of repoLocation uses to see if there was anything else
like this problem elsewhere, and didn't see any. But this is not the first
time this special case in git and git-annex's attempt to de-special-case
it has caused a problem..

avoid beware of the leopard situation
* Display a warning message when a remote uses a protocol, such as
  git://, that git-annex does not support. Silently skipping such a
  remote was confusing behavior.

  It sets annex-ignore, so the warning is only displayed once.

* Also display a warning message when a remote, without a known uuid,
  is located in a directory that does not currently exist, to avoid
  silently skipping such a remote.

  This is a bit more debatable, since git-annex get will say,
  try making repository available. And since it does not set annex-ignore,
  the warning will be displayed repeatedly. It's also an extreme edge case,
  I don't think I've ever seen it happen in real life.

external: stop storing readonly=true in remote.log
readonly=true is used to make an external special remote that does not
need the external program to be installed. It was stored in the
remote.log by default, and so every time it was specified in an
enableremote or initremote, whatever value was used became the new
default for subsequent enableremotes of that remote.

That was surprising, and I consider it to be a bug.

It does not make much sense to pass it to initremote because then how
would you populate that remote with anything? You would have to
enableremote elsewhere, and store content there. I'm assuming nobody
used it that way.

Someone might rely on passing it to enableremote once, and then that
being inherited in other clones. But that is not how it's documented to
be used. It is barely documented in git-annex at all, only in the
external special remote protocol, and the documentation there says to
"Document that this external special remote can be used in readonly
mode." (by the user of it passing readonly=true to enableremote). The
one external special remote that I know of that does document that is
<https://github.com/bgilbert/gcsannex> (the one that motivated adding
it). That one's docs do say to pass it to enableremote.

So, it seemed safe to make this behavior change. If someone was in fact
relying on one of those behaviors, all their current repos will still
work as they configured them (although they will need to deal
with the related change in 9f3c2dfeda).
In new clones, they will find enableremote fails, complaining the
external program is not in path. An easy enough problem to recover from.

fix bug involving local git remote and out of date location log
get --from, move --from: When used with a local git remote, these used to
silently skip files that the location log thought were present on the
remote, when the remote actually no longer contained them. Since that
behavior could be surprising, now instead display a warning.

I got very confused when I encountered this behavior, since it was silently
skipping a file I needed that whereis said was on the remote.

get without --from already displayed a "unable to access these remotes"
message, which while a bit misleading in that the remote is likely
accessible, but just doesn't contain the file, at least indicated something
went wrong.

Having get --from display a warning makes it in line with get
w/o --from, so seems certianly ok. It might be there are situations where
move --from is used, on eg a whole directory, and the user only wants to
move whatever is present in the remote, and is perfectly ok with files
that are not present being skipped. So I'm less sure about the new warning
being ok there. OTOH, only local git remotes avoiding displaying a warning
in that case too, so this just brings them into line with other remotes.

(Also note that this makes it a little bit faster when dealing with a lot of
files, since it avoids a redundant stat of the file.)

check-attr resource pool
Limited to min of -JN or number of CPU cores, because it will often be
CPU bound, once it's read the gitignore file for a directory.

In some situations it's more disk bound, but in any case it's unlikely
to be the main bottleneck that -J is used to avoid. Eg, when dropping,
this is used for numcopies checks, but the main bottleneck will be
accessing the remotes to verify presence. So the user might decide to
-J32 that, but having 32 check-attr processes would just waste however
many filehandles they open, and probably worsen their performance due to
CPU contention.

Note that, I first tried just letting up to the -JN be started. However,
even when it's no bottleneck at all, that still results in all of them
being started. Why? Well, all the worker threads start up nearly
simulantaneously, so there's a thundering herd..

cat-file resource pool
Avoid running a large number of git cat-file child processes when run with
a large -J value.

This implementation takes care to avoid adding any overhead to git-annex
when run without -J. When run with -J, there is a small bit of added
overhead, to manipulate the resource pool. That optimisation added a
fair bit of complexity.

fix a thundering herd problem
Avoid repeatedly opening keys db when accessing a local git remote and -J
is used.

What was happening was that Remote.Git.onLocal created a new annex state
as each thread started up. The way the MVar was used did not prevent that.
And that, in turn, led to repeated opening of the keys db, as well as
probably other extra work or resource use.

Also managed to get rid of Annex.remoteannexstate, and it turned out there
was an unncessary Maybe in the keysdbhandle, since the handle starts out
closed.
