Only one place remained that differentiated between them.
It is the case that a symlink target that happens to contain a newline
somehow will be treated as a link to a key truncated at the newline.
This is super unlikely to happen, and since a key cannot actually
contain a newline, it's as good a behavior as any. Anyway, this commit
does not change the behavior there, although arguably it should be
changed. Note that getAnnexLinkTarget does prevent a symlink target
containing a newline.

onAddUnlocked suggested that it had to add the file locked, but it
doesn't, it only queues the add of the file, and it's up to the
committer what to do -- which is currently indeed to always add the file
locked.
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.

assistant: When adding non-large files to git, honor annex.delayadd
configuration.
Also, don't add non-large files to git when they are still
being written to. This came for free, since the changes to non-large
files get queued up with the ones to large files, and run through the lsof
check.

Lots of nice wins from this in avoiding unncessary work, and I think
nothing got slower.
This commit was sponsored by Boyd Stephen Smith Jr. on Patreon.
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.
Added annex.skipunknown git config, that can be set to false to change the
behavior of commands like `git annex get foo*`, to not skip over files/dirs
that are not checked into git and are explicitly listed in the command
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.
Since it was used on both worktree and .git/annex files, split into
multiple functions.
In passing, this also improves permissions of created directories in
.git/annex, using createAnnexDirectory on those.
Adds a dependency on filepath-bytestring, an as yet unreleased fork of
filepath that operates on RawFilePath.
Git.Repo also changed to use RawFilePath for the path to the repo.
This does eliminate some RawFilePath -> FilePath -> RawFilePath
conversions. And filepath-bytestring's </> is probably faster.
But I don't expect a major performance improvement from this.
This is mostly groundwork for making Annex.Location use RawFilePath,
which will allow for a conversion-free pipleline.
warningIO is not concurrent output safe, and it doesn't go to
--json-error-messages
There are a few more that would be too hard to remove, and there are also
several dozen direct prints to stderr still.
This does not change the overall license of the git-annex program, which
was already AGPL due to a number of sources files being AGPL already.
Legally speaking, I'm adding a new license under which these files are
now available; I already released their current contents under the GPL
license. Now they're dual licensed GPL and AGPL. However, I intend
for all my future changes to these files to only be released under the
AGPL license, and I won't be tracking the dual licensing status, so I'm
simply changing the license statement to say it's AGPL.
(In some cases, others wrote parts of the code of a file and released it
under the GPL; but in all cases I have contributed a significant portion
of the code in each file and it's that code that is getting the AGPL
license; the GPL license of other contributors allows combining with
AGPL code.)
Now there's a ByteString used all the way from disk to Key.
The main complication in this conversion was the use of fromInternalGitPath
in several places to munge things on Windows. The things that used that
were changed to parse the ByteString using either path separator.
Also some code that had read from files to a String lazily was changed
to read a minimal strict ByteString.
Removed dependency on MissingH, instead depending on the split
library.
After laying groundwork for this since 2015, it
was mostly straightforward. Added Utility.Tuple and
Utility.Split. Eyeballed System.Path.WildMatch while implementing
the same thing.
Since MissingH's progress meter display was being used, I re-implemented
my own. Bonus: Now progress is displayed for transfers of files of
unknown size.

... to control the default behavior in all clones of a repository.
This includes a new Configurable data type, so the GitConfig type indicates
which values can be configured this way.
The implementation should be quite efficient; the config log is only read
once, and only when a Configurable value has not already been set by
git-config.
Indeed, it would be nice in the future to extend this, so that git-config
is itself only read on demand. Some commands may not need to look at the
git configuration at all.

ghc 8 added backtraces on uncaught errors. This is great, but git-annex was
using error in many places for a error message targeted at the user, in
some known problem case. A backtrace only confuses such a message, so omit it.
Notably, commands like git annex drop that failed due to eg, numcopies,
used to use error, so had a backtrace.

Previously, it only flushed when the queue got larger than 1.
Also, make the queue auto-flush when items are added, rather than needing
to be flushed as a separate step. This simplifies the code and make it more
efficient too, as it avoids needing to read the queue out of the state to
check if it should be flushed.
Fixes several bugs with updates of pointer files. When eg, running
git annex drop --from localremote
it was updating the pointer file in the local repository, not the remote.
Also, fixes drop ../foo when run in a subdir, and probably lots of other
problems. Test suite drops from ~30 to 11 failures now.
TopFilePath is used to force thinking about what the filepath is relative
to.
The data stored in the sqlite db is still just a plain string, and
TopFilePath is a newtype, so there's no overhead involved in using it in
DataBase.Keys.
This removes a bit of complexity, and should make things faster
(avoids tokenizing Params string), and probably involve less garbage
collection.
In a few places, it was useful to use Params to avoid needing a list,
but that is easily avoided.
Problems noticed while doing this conversion:
* Some uses of Params "oneword" which was entirely unnecessary
overhead.
* A few places that built up a list of parameters with ++
and then used Params to split it!
Test suite passes.
* init: Repository tuning parameters can now be passed when initializing a
repository for the first time. For details, see
http://git-annex.branchable.com/tuning/
* merge: Refuse to merge changes from a git-annex branch of a repo
that has been tuned in incompatable ways.
This is necessary for interop between inode caches created on unix and
windows. Which is more important than supporting inodecaches for large keys
with the wrong size, which are broken anyway.
There should be no slowdown from this change, except on Windows.
Found these with:
git grep "^ " $(find -type f -name \*.hs) |grep -v ': where'
Unfortunately there is some inline hamlet that cannot use tabs for
indentation.
Also, Assistant/WebApp/Bootstrap3.hs is a copy of a module and so I'm
leaving it as-is.
This fixes all instances of " \t" in the code base. Most common case
seems to be after a "where" line; probably vim copied the two space layout
of that line.
Done as a background task while listening to episode 2 of the Type Theory
podcast.
Removed old extensible-exceptions, only needed for very old ghc.
Made webdav use Utility.Exception, to work after some changes in DAV's
exception handling.
Removed Annex.Exception. Mostly this was trivial, but note that
tryAnnex is replaced with tryNonAsync and catchAnnex replaced with
catchNonAsync. In theory that could be a behavior change, since the former
caught all exceptions, and the latter don't catch async exceptions.
However, in practice, nothing in the Annex monad uses async exceptions.
Grepping for throwTo and killThread only find stuff in the assistant,
which does not seem related.
Command.Add.undo is changed to accept a SomeException, and things
that use it for rollback now catch non-async exceptions, rather than
only IOExceptions.
Only fsck and reinject and the test suite used the Backend, and they can
look it up as needed from the Key. This simplifies the code and also speeds
it up.
There is a small behavior change here. Before, all commands would warn when
acting on an annexed file with an unknown backend. Now, only fsck and
reinject show that warning.
Batch detection is heuristic, so can sometimes fail. I observed one such
failure while starting up in a repository with 87000 files. After the first
several batches of ~5000 files, it fell out of batch mode, and never
re-entered it, and so made many more commits of a few files at a time
than necessary.
So, let's always use batch mode when in the startup scan. This avoids the
heuristic there, at least.
There is clearly also room to improve the heuristic. Possibly 10 files is
too high a bar to be found during a commit, on a system that can commit
quickly.
