Using == and != proved too hard to read, so went with [TRUE] and [FALSE]
after the term. I would kind of liked to have used emojis for a green
check and red X, but probably that is too fancy to be a good idea.
Make --explain output be inside [ ] with whitespace around them, to
avoid it ending with eg "[FALSE]]" and to make it easier to visually
find the start of it.

And annex.largefiles and annex.addunlocked.
Also git-annex matchexpression --explain explains why its input
expression matches or fails to match.
When there is no limit, avoid explaining why the lack of limit
matches. This is also done when no preferred content expression is set,
although in a few cases it defaults to a non-empty matcher, which will
be explained.

Currently it only displays explanations of options like --in and --copies.
In the future, it should explain preferred content expression evaluation
and other decisions.
The explanations of a few things could be better. In particular,
"standard" will just appear as-is (or as "!standard" if it doesn't
match), rather than explaining why the standard preferred content expression
for the group matches or not.
Currently as implemented, it goes to stdout, and so commands like
git-annex find that have custom output will not display --explain
information. Perhaps that should change, dunno.

explain is a kind of debug message, but not formatted in the same way.
So it makes sense to reuse the debug machinery for it, since that is
already quite optimised.

For expire, the normal output is unchanged, but the --json output includes the uuid
in machine parseable form. Which could be very useful for this somewhat obscure
command. That needed ActionItemUUID to be implemented, which seemed like a lot
of work, but then ---
I had been going to skip implementing them for trust, untrust, dead, semitrust,
and describe, but putting the uuid in the json is useful information, it tells
what uuid git-annex picked given the input. It was not hard to support
these once ActionItemUUID was implemented.

When a nonexistant file is passed to a command and --json-error-messages
is enabled, output a JSON object indicating the problem.
(But git ls-files --error-unmatch still displays errors about such files in
some situations.)
I don't like the duplication of the name of the command introduced by this,
but I can't see a great way around it. One way would be to pass the Command
instead.
When json is not enabled, the stderr is unchanged. This is necessary
because some commands like find have custom output. So dislaying
"find foo not found" would be wrong. So had to complicate things with
toplevelFileProblem having different output with and without json.
When not using --json-error-messages but still using --json, it displays
the error to stderr, but does display a json object without the error. It
does have an errorid though. Unsure how useful that behavior is.

This reverts commit a325524454.
Turns out this was predicated on an incorrect belief that json output
didn't already sometimes lack the "key" field. Since json output already
can when `giveup` was used, it seems unncessary to add a whole new
option for this.
Added a --json-exceptions option, which makes some exceptions be output in json.
The distinction is that --json-error-messages is for messages relating
to a particular ActionItem, while --json-exceptions is for messages that
are not, eg ones for a file that does not exist.
It's unfortunate that we need two switches with such a fine distinction
between them, but I'm worried about maintaining backwards compatability
in the json output, to avoid breaking anything that parses it, and this was
the way to make sure I didn't.
toplevelWarning is generally used for the latter kind of message. And
the other calls to toplevelWarning could be converted to showException. The
only possible gotcha is that if toplevelWarning is ever called after
starting acting on a file, it will add to the --json-error-messages of the
json displayed for that file and converting to showException would be a
behavior change. That seems unlikely, but I didn't convery everything to
avoid needing to satisfy myself it was not a concern.

This does, as a side effect, make long notes in json output not

Converted warning and similar to use StringContainingQuotedPath. Most
warnings are static strings, some do refer to filepaths that need to be
quoted, and others don't need quoting.
Note that, since quote filters out control characters of even
UnquotedString, this makes all warnings safe, even when an attacker
sneaks in a control character in some other way.
When json is being output, no quoting is done, since json gets its own
quoting.

Added StringContainingQuotedPath, which is used for ActionItemOther.
In the process, checked every ActionItemOther for those containing
filenames, and made them use quoting.

This is by no means complete, but escaping filenames in actionItemDesc does
cover most commands.
Note that for ActionItemBranchFilePath, the value is branch:file, and I
choose to only quote the file part (if necessary). I considered quoting the
whole thing. But, branch names cannot contain control characters, and while
they can contain unicode, git coes not quote unicode when displaying branch
names. So, it would be surprising for git-annex to quote unicode in a
branch name.
The find command is the most obvious command that still needs to be
dealt with. There are probably other places that filenames also get
displayed, eg embedded in error messages.
Some other commands use ActionItemOther with a filename, I think that
ActionItemOther should either be pre-sanitized, or should explicitly not
be used for filenames, so that needs more work.
When --json is used, unicode does not get escaped, but control
characters were already escaped in json.
(Key escaping may turn out to be needed, but I'm ignoring that for now.)

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.

It can't enable or disable debug output, after recent changes, w/o
restarting git-annex, or perhaps messing with the Annex monad's
internals. Doesn't seem worth supporting it any longer.
Most of the changes here involve global option parsing: GlobalSetter
changed so it can both run an Annex action to set state, but can also
change the AnnexRead value, which is immutable once the Annex monad is
running.
That allowed a debugselector value to be added to AnnexRead, seeded
from the git config. The --debugfilter option's GlobalSetter then updates
the AnnexRead.
This improved GlobalSetter can later be used to move more stuff to
AnnexRead. Things that don't involve a git config will be easier to
move, and probably a *lot* of things can be moved eventually.
fastDebug, while implemented, is not used anywhere yet. But it should be
fast..
This uses a DebugSelector, rather than debug levels, which will allow
for a later option like --debug-from=Process to only
see debuging about running processes.
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.
Like import was using ActionItemWorkTreeFile, it's ok to use it for export,
even though it might not correspond with a file in the work tree.
And renamed it to ActionItemTreeFile to make that clearer.
Note that when an export has to rename files, it still uses
ActionItemOther, so file will still be null in that case, but as no file is
being transferred, that seems ok.
That seems to be the last thing needed for message serialization.
Although it's only used in the assistant currently, so hard to tell if I
forgot something.
At this point, it should be possible to start using transferkeys
when performing transfers, which will allow killing a transferkeys
process if a transfer times out or stalls. But that's for another day.
This commit was sponsored by Ethan Aubin.
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.
This commit was sponsored by Ethan Aubin.
Necessarily threw out the old protocol, so if an old git-annex assistant
is running, and starts a transferkeys from the new git-annex, it would
fail. But, that seems unlikely; the assistant starts up transferkeys
processes and then keeps them running. Still, may need to test that
scenario.
The new protocol is simple read/show and looks like this:
TransferRequest Download (Right "origin") (Key {keyName = "f8f8766a836fb6120abf4d5328ce8761404e437529e997aaa0363bdd4fecd7bb", keyVariety = SHA2Key (HashSize 256) (HasExt True), keySize = Just 30, keyMtime = Nothing, keyChunkSize = Nothing, keyChunkNum = Nothing}) (AssociatedFile (Just "foo"))
TransferOutput (ProgressMeter (Just 30) (MeterState {meterBytesProcessed = BytesProcessed 0, meterTimeStamp = 1.6070268727892535e9}) (MeterState {meterBytesProcessed = BytesProcessed 30, meterTimeStamp = 1.6070268728043e9}))
TransferOutput (OutputMessage "(checksum...) ")
TransferResult True
Granted, this is not optimally fast, but it seems good enough, and is
probably nearly as fast as the old protocol anyhow.
emitSerializedOutput for ProgressMeter is not yet implemented. It needs
to somehow start or update a progress meter. There may need to be a new
message that allocates a progress meter, and then have ProgressMeter
update it.

Json objects not yet handled, and some other special cases, but this is

With some hints for the user for what to do.
Took care to avoid changing the json output. It would have been ok to add
the new separated lists to it, in addition to the old list, but I didn't
do that because I didn't see much point.
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.
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.
If git-credential has it cached and does not prompt, this will
unfortunately result in a brief flicker, as the displayed console
regions are hidden while running it and then re-displayed. Better than a
corrupted display.
Actually, I tried it and don't see a visible flicker, so probably only
over a slow ssh will it be apparent.
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.
Reversion from commit 436f10771, CustomOutput was forcing quiet output
which overrode the json setting.
find happened to be the only command that uses CustomOutput and also
outputs json. (metadata --get does also use CustomOutput and --json does not
enable json output for that, which may be an oversight, but was already the
behavior before this regression.)
Fixes the last wart in the StartMessage transition. A few commands
include other CommandStart actions that generate output, and
do not themselves need to display a start/end message.
Oh joyous day, this is probably git-annex's oldest implementation wart,
source of much unncessary bother.
Now that we have a StartMessage, showEndResult' can look at it to know
if it needs to display an end message or not.
This is also going to be faster, because it avoids an uncessary state
lookup for each file processed.
The hoped for optimisation of CommandStart with -J did not materialize.
In fact, not runnign CommandStart in parallel is slower than -J3.
So, CommandStart are still run in parallel.
(The actual bad performance I've been seeing with -J in my big repo
has to do with building the remoteList.)
But, this is still progress toward making -J faster, because it gets rid
of the onlyActionOn roadblock in the way of making CommandCleanup jobs
run separate from CommandPerform jobs.
Added OnlyActionOn constructor for ActionItem which fixes the
onlyActionOn breakage in the last commit.
Made CustomOutput include an ActionItem, so even things using it can
specify OnlyActionOn.
In Command.Move and Command.Sync, there were CommandStarts that used
includeCommandAction, so output messages, which is no longer allowed.
Fixed by using startingCustomOutput, but that's still not quite right,
since it prevents message display for the includeCommandAction run
inside it too.
