using git credential to get the password
One thing this doesn't do is wrap the password prompting inside the prompt
action. So with -J, the output can be a bit garbled.
The use case is basically the user having forgotten, so --help would be
best, but it would be quite hard to include this in --help, since it may
even have to spin up an external special remote program.
I also considered --umm but typoed it the first time I tried it as
--uum, and while memorable, it's too cutesy. --whatelse is good because
it explicitly asks, what other params, besides the ones I've given?
preferreddir can be used with any special remote, so its parser needs to
be included in the commonFieldParsers.
initremote with uuid= changed to delete that field, so it does not
need to be included in commonFieldParsers. Note that, existing remotes
initialized before this change will have the field in remote.log.
This will not cause problems parsing, because the value will be
Accepted.
Grepping for 'Accepted "' found these, and I'm pretty sure this is all of
them.
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.
This avoids hardcoding the sha size, so when git uses sha256, it will
output the full sha256 and not a truncation to 40 characters.
I reviewed git's history, and while there have been some
bugs with commands not supporting --no-abbrev (eg git diff --no-index
--no-abbrev was broken in git 2.1), none of the commands git-annex
uses will be impacted by those old bugs.
Git will eventually switch to sha2 and there will not be one single
shaSize anymore, but two (40 and 64).
Changed all parsers for git plumbing output to support both sizes of
shas.
One potential problem this does not deal with is, if somewhere in
git-annex it reads two shas from different sources, and compares them
to see if they're the same sha, it would fail if they're sha1 and sha256
of the same value. I don't know if that will really be a concern.
ifAnnexed in a bare repo passes to git cat-file :./filename , which it
refuses to do since the repo is bare.
Note that, reinject somefile someannexedfile in a bare repo silently does
nothing, because someannexedfile is never actually an annexed worktree
file, because the repo is bare.
options make it easier to override annex.largefiles configuration
(and potentially safer as it avoids bugs like the smudge bug fixed
in the last release)
Deleted some old comments that were posted to the man page discussing such
options.
Updated docs that used -c annex.largefiles to use the options.
Note that addSmallOverridden was needed to avoid the clean filter running
on the file. It would be possible to make addFile also update the index
directly, rather than going via git add. However, it was not necessary,
and I want to avoid breaking on some edge case, particularly if the code in
addSmallOverridden has some oversight.
Also, when annex.addunlocked is set and annex.largefiles does not match a file,
git annex add --force-large works, but git status will then show the file
as added, with a unstaged modification. The unstaged modification adds the
file to git. This is identical behavior to using -c annex.largefiles=nothing
when annex.addunlocked is set. This does not prevent committing what was
intended to be added. I have not gotten to the bottom of why git thinks
the file is modified and runs it through the clean filter in this case.
smudge: When annex.largefiles=anything, files that were already stored in
git, and have not been modified could sometimes be converted to being
stored in the annex. Changes in 7.20191024 made this more of a problem.
This case is now detected and prevented.
* annex.addunlocked can be set to an expression with the same format used by
annex.largefiles, in case you want to default to unlocking some files but
not others.
* annex.addunlocked can be configured by git-annex config.
Added a git-annex-matching-expression man page, broken out from
tips/largefiles.
A tricky consequence of this is that git-annex add --relaxed
honors annex.addunlocked, but an expression might want to know the size
or content of an url, which it's not going to download. I decided it was
better not to fail, and just dummy up some plausible data in that case.
Performance impact should be negligible. The global config is already
loaded for annex.largefiles. The expression only has to be parsed once,
and in the simple true/false case, it should not do any additional work
matching it.
e53070c1f quietly made it set the local git config too, but that was never
documented anywhere, and it had surprising results. If I set
annex.largefiles globally in a repo, I would expect to be able to change it
in another repo, and the original repo would get the change and use it,
rather than being stuck on the old value set there.
And, if I have a local annex.largefiles and set a different global default,
I'd be surprised to have my local setting overwritten.
annex.securehashesonly does need to be set locally, since it's a security
feature and the global is only a default until it gets set locally. So
special cased.
Remove dup definitions and just use the RawFilePath one. </> etc are
enough faster that it's probably faster than building a String directly,
although I have not benchmarked.
git-annex find is now RawFilePath end to end, no string conversions.
So is git-annex get when it does not need to get anything.
So this is a major milestone on optimisation.
Benchmarks indicate around 30% speedup in both commands.
Probably many other performance improvements. All or nearly all places
where a file is statted use RawFilePath now.
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.
Only done on those calls to getFileStatus that had a RawFilePath, not a
FilePath. The others would probably be just as fast if converted to use
it with toRawFilePath, but I'm not 100% sure.
Note that genInodeCache' uses fromRawFilePath, but that value only gets
used on Windows, so on unix the thunk will never be evaluated.
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.
This will speed up the common case where a Key is deserialized from
disk, but is then serialized to build eg, the path to the annex object.
Previously attempted in 4536c93bb2
and reverted in 96aba8eff7.
The problems mentioned in the latter commit are addressed now:
Read/Show of KeyData is backwards-compatible with Read/Show of Key from before
this change, so Types.Distribution will keep working.
The Eq instance is fixed.
Also, Key has smart constructors, avoiding needing to remember to update
the cached serialization.
Used git-annex benchmark:
find is 7% faster
whereis is 3% faster
get when all files are already present is 5% faster
Generally, the benchmarks are running 0.1 seconds faster per 2000 files,
on a ram disk in my laptop.
* benchmark: Changed --databases to take a parameter specifiying the size
of the database to benchmark.
* benchmark --databases: Display size of the populated database.
* benchmark --databases: Improve the "addAssociatedFile to (new)"
benchmark to really add new values, not overwriting old values.
Convert Utility.Url to return Either String so the error message can be
displated in the annex monad and so captured.
(When curl is used, its errors are still not caught.)
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.
Added annex.gitaddtoannex configuration. Setting it to false prevents
git add from usually adding files to the annex.
(Unless the file was annexed before, or a renamed annexed file is detected.)
Currently left at true; some users are encouraging it be set to false.
Renamed unlocked files are now detected, and will always be
annexed, unless annex.largefiles disallows it.
This allows for git add's behavior to later be changed to otherwise
not annex files (whether by default or as a config option), without
worrying about the rename case.
This is not a major behavior change; annexing is still the default. But
there is one case where the behavior is changed, I think for the better:
touch f
git -c annex.largefiles=nothing add f
git add bigfile
git commit -m ...
mv bigfile f
git add f
Before, git-annex would see that f was previously not annexed,
and so the renamed bigfile content gets added to git. Now, it notices
that the inode is the one that bigfile used, and so it annexes it.
This potentially slows down git add a lot in some repositories because
of the poor performance of isInodeKnown when there are a lot of unlocked
files. Configuring annex.largefiles avoids the speed hit.
This solves the problem of sameas remotes trampling over per-remote
state. Used for:
* per-remote state, of course
* per-remote metadata, also of course
* per-remote content identifiers, because two remote implementations
could in theory generate the same content identifier for two different
peices of content
While chunk logs are per-remote data, they don't use this, because the
number and size of chunks stored is a common property across sameas
remotes.
External special remote had a complication, where it was theoretically
possible for a remote to send SETSTATE or GETSTATE during INITREMOTE or
EXPORTSUPPORTED. Since the uuid of the remote is typically generate in
Remote.setup, it would only be possible to pass a Maybe
RemoteStateHandle into it, and it would otherwise have to construct its
own. Rather than go that route, I decided to send an ERROR in this case.
It seems unlikely that any existing external special remote will be
affected. They would have to make up a git-annex key, and set state for
some reason during INITREMOTE. I can imagine such a hack, but it doesn't
seem worth complicating the code in such an ugly way to support it.
Unfortunately, both TestRemote and Annex.Import needed the Remote
to have a new field added that holds its RemoteStateHandle.
