fix breakage in wormhole's sendFile
Commit ff0927bde9 broke this, it made it
try to read all of the input before looking for the code. But, wormhole
keeps running until it sends the file, so that caused a deadlock. Oops.

fix wormhole --appid option position
p2p: Pass wormhole the --appid option before the receive/send command, as
it does not accept that option after the command

I'm left wondering, did I get this wrong from the beginning, or did
wormhole change its option parser? I'm reminded of the change in 0.8.2
where it silently changed what FD the pairing code was output to.
But, looking at the wormhole source, it was at least putting --appid before
send in its test suite from the introduction of the option.

So I think probably this has always been broken. On 2021-12-31 the --appid
option was enabled, and it took until now for someone to try
git-annex p2p --pair and notice that flag day broke it..

deal with ignoreinode config setting
Improve handling of directory special remotes with importtree=yes whose
ignoreinode setting has been changed. (By either enableremote or by
upgrading to commit 3e2f1f73cbc5fc10475745b3c3133267bd1850a7.)

When getting a file from such a remote, accept the content that would have
been accepted with the previous ignoreinode setting.

After a change to ignoreinode, importing a tree from the remote will
re-import and generate new content identifiers using the new config. So
when ignoreinode has changed to no, the inodes will be learned, and after
that point, a change in an inode will be detected as a change. Before
re-importing, a change in an inode will be ignored, as it was before the
ignoreinode change. This seems acceptble, because the user can re-import
immediately if they urgently need to add inodes. And if not, they'll
do it sometime, presumably, and the change will take effect then.

use getSymbolicLinkStatus not getFileStatus to avoid crash on broken symlink
Fix crash importing from a directory special remote that contains a broken
symlink.

The crash was in listImportableContentsM but some other places in
Remote.Directory also seemed like they could have the same problem.

Also audited for other places that have such a problem. Not all calls
to getFileStatus are bad, in some cases it's better to crash on something
unexpected. For example, `git-annex import path` when the path is a broken
symlink should crash, the same as when it does not exist. Many of the
getFileStatus calls are like that, particularly when they involve
.git/annex/objects which should never have a broken symlink in it.

Fixed a few other possible cases of the problem.

Added support for "megabit" and related bandwidth units in
annex.stalldetection and everywhere else that git-annex parses data units.

Note that the short form is "Mbit" not "Mb" because that differs from "MB"
only in case, and git-annex parses units case-insensitively. It would be
horrible if two different versions of git-annex parsed the same value
differently, so I don't think "Mb" can be supported.

avoid using removePathForcibly everywhere, it is unsafe
If the temp directory can somehow contain a hard link, it changes the
mode, which affects all other hard linked files. So, it's too unsafe
to use everywhere in git-annex, since hard links are possible in
multiple ways and it would be very hard to prove that every place that
uses a temp directory cannot possibly put a hard link in it.

Added a call to removeDirectoryForCleanup to test_crypto, which will
fix the problem that commit 17b20a2450
was intending to fix, with a much smaller hammer.

* Prevent Key from being re-exported by Utilities.Aeson, as it clashes
  with git-annex's own Key type.

* Fix up convertion from String/Text to Key (or Text in aeson 1.*) in a
  couple of places

* Import Data.Aeson.KeyMap instead of Data.HashMap.Strict, as they are
  mostly API-compatible. insertWith needs to be replaced by unionWith,

close pid lock only once no threads use it
This fixes a FD leak when annex.pidlock is set and -J is used. Also, it
fixes bugs where the pid lock file got deleted because one thread was
done with it, while another thread was still holding it open.

The LockPool now has two distinct types of resources,
one is per-LockHandle and is used for file Handles, which get closed
when the associated LockHandle is closed. The other one is per lock
file, and gets closed when no more LockHandles use that lock file,
including other shared locks of the same file.

That latter kind is used for the pid lock file, so it's opened by the
first thread to use a lock, and closed when the last thread closes a lock.

In practice, this means that eg git-annex get of several files opens and
closes the pidlock file a few times per file. While with -J5 it will open
the pidlock file, process a number of files, until all the threads happen to
finish together, at which point the pidlock file gets closed, and then
that repeats. So in either case, another process still gets a chance to
take the pidlock.

registerPostRelease has a rather intricate dance, there are fine-grained
STM locks, a STM lock of the pidfile itself, and the actual pidlock file
on disk that are all resolved in stages by it.

Revert "fix too early close of shared lock file"
This reverts commit 66b2536ea0.

I misunderstood commit ac56a5c2a0
and caused a FD leak when pid locking is not used.

A LockHandle contains an action that will close the underlying lock
file, and that action is run when it is closed. In the case of a shared
lock, the lock file is opened once for each LockHandle, and only
the one for the LockHandle that is being closed will be closed.

fine-grained locking when annex.pidlock is enabled
This locking has been missing from the beginning of annex.pidlock.
It used to be possble, when two threads are doing conflicting things,
for both to run at the same time despite using locking. Seems likely
that nothing actually had a problem, but it was possible, and this
eliminates that possible source of failure.

avoid concurrent threads trying to take pid lock at same time
Seem there are several races that happen when 2 threads run PidLock.tryLock
at the same time. One involves checkSaneLock of the side lock file, which may
be deleted by another process that is dropping the lock, causing checkSaneLock
to fail. And even with the deletion disabled, it can still fail, Probably due
to linkToLock failing when a second thread overwrites the lock file.

The same can happen when 2 processes do, but then one process just fails
to take the lock, which is fine. But with 2 threads, some actions where failing
even though the process as a whole had the pid lock held.

Utility.LockPool.PidLock already maintains a STM lock, and since it uses
LockShared, 2 threads can hold the pidlock at the same time, and when
the first thread drops the lock, it will remain held by the second
thread, and so the pid lock file should not get deleted until the last
thread to hold it drops the lock. Which is the right behavior, and why a
LockShared STM lock is used in the first place.

The problem is that each time it takes the STM lock, it then also calls
PidLock.tryLock. So that was getting called repeatedly and concurrently.

Fixed by noticing when the shared lock is already held, and stop calling
PidLock.tryLock again, just use the pid lock that already exists then.

Also, LockFile.PidLock.tryLock was deleting the pid lock when it failed
to take the lock, which was entirely wrong. It should only drop the side
lock.

resume properly when copying a file to/from a local git remote is interrupted (take 2)
This method avoids breaking test_readonly. Just check if the dest file
exists, and avoid CoW probing when it does, so when CoW probing fails,
it can resume where the previous non-CoW copy left off.

If CoW has been probed already to work, delete the dest file
since a CoW copy will presumably work. It seems like it would be almost
as good to just skip CoW copying in this case too, but consider that the
dest file might have started to be copied from some other remote, not
using CoW, but CoW has been probed to work to copy from the current
place.

avoid potentially very long bwlimit delay at start
I first saw this getting with -J2 over ssh, but later saw it also
without the -J2. It was resuming, and the calulated unboundDelay was
many minutes. The first update of the meter jumped to some large value,
because of the resuming, and so it thought the BW was super fast.

Avoid by waiting until the second meter update.

Might be a good idea to also guard for the delay being many seconds
and avoid waiting. But how many? If BW is legitimately super fast, and a
remote happens to read more than a 32kb or so chunk at a time, it could
in theory download megabytes or gigabytes of data before the first meter
update. It would actually be appropriate then to delay for a long time,
if the desired BW was low. Could make up some numbers that are sane now,
but tech may improve.

(BTW, pleased to see bwlimit does work with -J. I had worried that
it might not, if the meter update happened in a different thread than
the downloading, but it's done in the same thread.)

resume properly when copying a file to/from a local git remote is interrupted
Probably this fixes a reversion, but I don't know what version broke it.

This does use withOtherTmp for a temp file that could be quite large.
Though albeit a reflink copy that will not actually take up any space
as long as the file it was copied from still exists. So if the copy cow
succeeds but git-annex is interrupted just before that temp file gets
renamed into the usual .git/annex/tmp/ location, there is a risk that
the other temp directory ends up cluttered with a larger temp file than
later. It will eventually be cleaned up, and the changes of this being
a problem are small, so this seems like an acceptable thing to do.

bwlimit
Added annex.bwlimit and remote.name.annex-bwlimit config that works for git
remotes and many but not all special remotes.

This nearly works, at least for a git remote on the same disk. With it set
to 100kb/1s, the meter displays an actual bandwidth of 128 kb/s, with
occasional spikes to 160 kb/s. So it needs to delay just a bit longer...
I'm unsure why.

However, at the beginning a lot of data flows before it determines the
right bandwidth limit. A granularity of less than 1s would probably improve
that.

And, I don't know yet if it makes sense to have it be 100ks/1s rather than
100kb/s. Is there a situation where the user would want a larger
granularity? Does granulatity need to be configurable at all? I only used that
format for the config really in order to reuse an existing parser.

This can't support for external special remotes, or for ones that
themselves shell out to an external command. (Well, it could, but it
would involve pausing and resuming the child process tree, which seems
very hard to implement and very strange besides.) There could also be some
built-in special remotes that it still doesn't work for, due to them not
having a progress meter whose displays blocks the bandwidth using thread.
But I don't think there are actually any that run a separate thread for
downloads than the thread that displays the progress meter.

incremental verification for web special remote
Except when configuration makes curl be used. It did not seem worth
trying to tail the file when curl is downloading.

But when an interrupted download is resumed, it does not read the whole
existing file to hash it. Same reason discussed in
commit 7eb3742e4b76d1d7a487c2c53bf25cda4ee5df43; that could take a long
time with no progress being displayed. And also there's an open http
request, which needs to be consumed; taking a long time to hash the file
might cause it to time out.

Also in passing implemented it for git and external special remotes when
downloading from the web. Several others like S3 are within striking

IncrementalVerifier moved to Utility.Hash, which will let Utility.Url
use it later.

It's perhaps not really specific to hashing, but making a separate
module just for the data type seemed unncessary.

simplify and speed up Utility.FileSystemEncoding
This eliminates the distinction between decodeBS and decodeBS', encodeBS
and encodeBS', etc. The old implementation truncated at NUL, and the
primed versions had to do extra work to avoid that problem. The new
implementation does not truncate at NUL, and is also a lot faster.
(Benchmarked at 2x faster for decodeBS and 3x for encodeBS; more for the
primed versions.)

Note that filepath-bytestring 1.4.2.1.8 contains the same optimisation,
and upgrading to it will speed up to/fromRawFilePath.

AFAIK, nothing relied on the old behavior of truncating at NUL. Some
code used the faster versions in places where I was sure there would not
be a NUL. So this change is unlikely to break anything.

Also, moved s2w8 and w82s out of the module, as they do not involve
filesystem encoding really.

showSideActionAfter has some ugly caveats, since it has to display in

assistant: Fix a crash on startup by avoiding using forkProcess
ghc 8.8.4 seems to have changed something that broke code that has been
successfully using forkProcess since 2012. Likely a change to GC internals.

Since forkProcess has never had clear documentation about how to
use it safely, avoid using it at all. Instead, when git-annex needs to
daemonize itself, re-run the git-annex command, in a new process group

fileRef: make paths relative and simplified
Fix behavior of several commands, including reinject, addurl, and rmurl
when given an absolute path to an unlocked file, or a relative path that
leaves and re-enters the repository.

To avoid slowing down all the cases where the paths are already ok
with an unncessary call to getCurrentDirectory, put in an optimisation
in relPathCwdToFile. That will probably also speed up other parts of
git-annex by some small amount, but I have not benchmarked.

Note that I did not convert branchFileRef, because it seems likely that
it will be used with a file that is not provided by the user, so is already
in a sane format. This is certainly true for the way git-annex uses it,
though maybe arguable to the extent Git.Ref is a reusable library.

This uses a DebugSelector, rather than debug levels, which will allow
for a later option like --debug-from=Process to only

The module name that contains the thing being debugged is used as the
DebugSelector (in most cases; does not need to be a hard and fast rule).
Debug calls were changed to add that. hslogger did not display
that first parameter to debugM, but the DebugSelector does get
displayed.

Also fastDebug will allow doing debugging in places that are used in
tight loops, with the DebugSelector coming from the Annex Reader
essentially for free. Not done yet.

incremental checksum on download from ssh or p2p
Checksum as content is received from a remote git-annex repository, rather
than doing it in a second pass.

Not tested at all yet, but I imagine it will work!

Not implemented for any special remotes, and also not implemented for
copies from local remotes. It may be that, for local remotes, it will
suffice to use rsync, rely on its checksumming, and simply return Verified.
(It would still make a checksumming pass when cp is used for COW, I guess.)

while on linux, it does drop a leading / (which is what it considers
to be equivilant to a drive letter. I had been relying on it to drop
both. So need to drop leading directory separators.

Also, if the quickcheck generated input is eg "c:c:c:c:foo",
dropDrive will only drop the first one, leaving a path that's
still not relative. So instead of using dropDrive, just remove the
colons from the path.

omit inode from ContentIdentifier for directory special remote
Directory special remotes with importtree=yes now avoid unncessary overhead
when inodes of files have changed, as happens whenever a FAT filesystem
gets remounted.

A few unusual edge cases of modifications won't be detected and
imported. I think they're unusual enough not to be a concern. It would
be possible to add a config setting that controls whether to compare
inodes too, but does not seem worth bothering the user about currently.

I chose to continue to use the InodeCache serialization, just with the
inode zeroed. This way, if I later change my mind or make it
configurable, can parse it back to an InodeCache and operate on it. The
overhead of storing a 0 in the content identifier log seems worth it.

There is a one-time cost to this change; all directory special remotes
with importtree=yes will re-hash all files once, and will update the
content identifier logs with zeroed inodes.

fix prop_relPathDirToFileAbs_basics fail on windows
It was just slapping on a path separator to the front of the path to
make it absolute, but on windows, a path like "//foo/bar" actually
has a network "drive" of "//foo" and so that broke the test case.

Since "a:foo" is a somehow relative path on windows
(who knows how), drop any drive from the input. But dropDrive also drops
any leading path separator, making the input path relative. So now
it should be safe to slapp on a leading path separator.

entire content of the file is actually already present locally.

What a mess that Request can throw exceptions or not, depending on how
it's configured. Makes it very hard if you need to handle some specific
http status codes in a function like this! Implementing everything two
ways did not seem appealing, if possible at all, so I decided to
override the Request if it did come configured to throw exception on
non-2xx http status. Other exceptions, like from http-client-restricted,
or due to a redirect to a non-http url, still get thrown.

  which would count wide unicode characters as a single character.
  Changing to B.length changes that. Note that, git-annex's
  annexMaxExtensionLength already changed to the length in bytes
  before this change. This function is only used in generating views,
  and the small behavior change should not be a problem.
* relHome still uses FilePath because it didn't seem worth changing(?)

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.

Parse youtube-dl progress output
Which lets progress be displayed when doing concurrent downloads.
Amoung other things, like --json-progress etc.

The youtube-dl output is no longer displayed, except for any errors.

import --no-content: Check annex.largefiles
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.

remove zombie process in file seeking
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.

make MatchFiles introspectable
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.

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.)
