This is conceptually very simple, just making a 1 that was hard coded be
exposed as a config option. The hard part was plumbing all that, and
dealing with complexities like reading it from git attributes at the
same time that numcopies is read.
Behavior change: When numcopies is set to 0, git-annex used to drop
content without requiring any copies. Now to get that (highly unsafe)
behavior, mincopies also needs to be set to 0. It seemed better to
remove that edge case, than complicate mincopies by ignoring it when
numcopies is 0.

Especially from borg, where the content identifier logs
all end up being the same identical file!
But also, for other imports, the location tracking logs can,
in some cases, be identical files.
Bonus optimisation: Avoid looking up (and parsing when set)
GIT_ANNEX_VECTOR_CLOCK env var every time a log is written to.
Although the lookup does happen at startup even when no
log will be written now.
Still some issues to deal with, see TODO and XXX.
Here's what gets logged, for each key:
cid log:
1608582045.832799227s 6720ebad-b20e-4460-a8f2-2477361aea75 !MjAyMC0xMi0yMVQxMTozMzoxNw==:!MjAyMC0xMi0yMVQxMzowNzoyNg==
The "!Mj" are base64 encoded borg archive names, since mine were
dates and contained some characters not allowed in cid logs unescaped.
There were archives that each contained the key. This list will grow as
more borg backups are done and learned about.

This is to avoid breakage when upgrading or downgrading git-annex with a
process running that uses the interface. It's better to keep the
compatability code for a few years than worry about such breakage.

New config annex.stalldetection, remote.name.annex-stalldetection, which
can be used to deal with remotes that stall during transfers, or are
sometimes too slow to want to use.
This commit was sponsored by Luke Shumaker on Patreon.
This old code will now be useful for git-annex beyond the assistant.
git-annex won't use the CheckTransferrer part, and won't run transferkeys
as a batch process, and will want withTransferrer to not shut down
transferkeys processes. Still, the rest of this is a good fit for what I
need now.
Also removed some dead code, and simplified a little bit.

Any given transfer can only display 1 progress meter at a time, or so
this code assumes. In some cases, there are progress meters for
different stages of a transfer, perhaps, and that is supported by this.

Added annex.adjustedbranchrefresh git config to update adjusted branches
set up by git-annex adjust --unlock-present/--hide-missing.
Note, in a few cases, I was not able to make the adjusted branch
be updated in calls to moveAnnex, because information about what
file corresponds to a key is not available. They are:
* If two files point to one file, then eg, `git annex get foo` will
update the branch to unlock foo, but will not unlock bar, because it
does not know about it. Might be fixable by making `git annex get
bar` do something besides skipping bar?
* git-annex-shell recvkey likewise (so sends over ssh from old versions
of git-annex)
* git-annex setkey
* git-annex transferkey if the user does not use --file
* git-annex multicast sends keys with no associated file info
Doing a single full refresh at the end, after any incremental refresh,
will deal with those edge cases.
This will let a module that Annex.Content imports use inAnnex.
Unsure yet if I will need that, but this split still seems to make
sense, and Annex.Content was way too long so splitting it is good.
All properties changed to use them, except for
prop_encode_c_decode_c_roundtrip, which already filtered to ascii
for other reasons.
A few modules had to be split out, because Setup does not build-depend
on QuickCheck.
Had to split out some modules because getWorkingDirectory needs unix,
which is not a build-dep of configure.

John Thorvald Wodder II got it working using
https://github.com/datalad/file-windows so don't hard-disable it.
The stack.yaml still disables this build flag, because it needs an extra
C library to be installed, which stack cannot automate.
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.

Only turning it off when the criterion library is not installed.
Not enabled for osx or i386ancient yet since that will need some
invesitgation to update their respective stack.yaml files.
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..

"http" was too generic and easy to confuse with web. The new name makes
clear it's used in addition to some other remote. And other protocols
can use the same naming scheme.
This adds a dep on hashable, but it's a free dependency, since
unordered-containers already pulled it in.
Using unordered-containers for the set seems to make sense, since it
hashes and bloom filter hashes too. (Though different hashes.)
I dunno, never quite know if I should use unordered-containers or containers.
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

Network.HTTP.Client exports makeConnection since 0.5.3.
Debian stable has a newer version than 0.5.3, so bumping the
min version seems better than adding an ifdef.
Remove old code that can be trivially implemented using async in a much
nicer way (that is async exception safe).
I've audited all forkOS calls (except for ones in the assistant),
and this was the last remaining one that is not async exception safe.
The rest look ok to me.
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.)
* 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.
Extensions got renamed.
Default-Language is required. I had to put Haskell98 because there are
subtle differences between 98 and 2010 and git-annex has always been
built with the default, which was 98 when there was a default. I don't
know how to establish that git-annex will behave the same under 2010.
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.
This does mean that RemoteDaemon.Transport.Tor's call runs it, otherwise
no change, but this is groundwork for doing more such expensive actions
in dupState.
This was very susprising to me that it was not caught by -Wall, so I
enabled -Wincomplete-uni-patterns to catch such things. It found a
second one just lines above, but no others anywhere.
Remote now contains a ParsedRemoteConfig. The parsing happens when the
Remote is constructed, rather than when individual configs are used.
This is more efficient, and it lets initremote/enableremote
reject configs that have unknown fields or unparsable values.
It also allows for improved type safety, as shown in
Remote.Helper.Encryptable where things that used to match on string
configs now match on data types.
This is a work in progress, it does not build yet.
The main risk in this conversion is forgetting to add a field to
RemoteConfigParser. That will prevent using that field with
initremote/enableremote, and will prevent remotes that already are set
up from seeing that configuration. So will need to check carefully that
every field that getRemoteConfigValue is called on has been added to
RemoteConfigParser.
(One such case I need to remember is that credPairRemoteField needs to be
included in the RemoteConfigParser.)
This is a first step toward that goal, using the ProposedAccepted type
in RemoteConfig lets initremote/enableremote reject bad parameters that
were passed in a remote's configuration, while avoiding enableremote
rejecting bad parameters that have already been stored in remote.log
This does not eliminate every place where a remote config is parsed and a
default value is used if the parse false. But, I did fix several
things that expected foo=yes/no and so confusingly accepted foo=true but
treated it like foo=no. There are still some fields that are parsed with
yesNo but not not checked when initializing a remote, and there are other
fields that are parsed in other ways and not checked when initializing a
remote.
This also lays groundwork for rejecting unknown/typoed config keys.
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.
Since the sqlite branch uses blobs extensively, there are some
performance benefits, ByteStrings now get stored and retrieved w/o
conversion in some cases like in Database.Export.
File mode is octal not decimal. This broke in the conversion to
attoparsec.
(I've submitted the content of Utility.Attoparsec to the attoparsec
developers.)
Test suite passes 100% now.
Finally builds (oh the agoncy of making it build), but still very
unmergable, only Command.Find is included and lots of stuff is badly
hacked to make it compile.
Benchmarking vs master, this git-annex find is significantly faster!
Specifically:
num files old new speedup
48500 4.77 3.73 28%
12500 1.36 1.02 66%
20 0.075 0.074 0% (so startup time is unchanged)
That's without really finishing the optimization. Things still to do:
* Eliminate all the fromRawFilePath, toRawFilePath, encodeBS,
decodeBS conversions.
* Use versions of IO actions like getFileStatus that take a RawFilePath.
* Eliminate some Data.ByteString.Lazy.toStrict, which is a slow copy.
* Use ByteString for parsing git config to speed up startup.
It's likely several of those will speed up git-annex find further.
And other commands will certianly benefit even more.
Goal is to make git-annex faster by using ByteString for all the
worktree traversal. For now, this is focusing on Command.Find,
in order to benchmark how much it helps. (All other commands are
temporarily disabled)
Currently in a very bad unbuildable in-between state.
Renamed the database to .git/annex/keysdb;
the old .git/annex/keys gets deleted during the upgrade.
It is possible that an old git-annex process is running during the
upgrade. If so, it will be able to continue using the old keys db until the
upgrade is complete, and then will presumably fail in some ugly way. Or
perhaps the upgrade will be unable to delete the open files on some
systems, and so fail with an ugly error message.
It's also possible for multiple processes to be running the upgrade
concurrently. That should be fine; they will both write the same
information into the keys db.
Other databases still need to be upgraded.
Rescued from commit 11d6e2e260 which removed
db benchmarks in favor of benchmarking arbitrary git-annex commands. Which
is nice and general, but microbenchmarks are useful too.
It would have been a lot less round-about to just make git annex dead
also add the uuids of sameas remotes to the trust.log as dead.
But, that would fail in the case where there's an unmerged other clone
that has a sameas remote that the current repo does not know about.
Then it would not get marked as dead.
Handling it at transition time avoids that scenario.
Note that the generation of trustmap' in dropDead should only
happen once, due to the partial application.
