remoteAnnexConfig will avoid bugs like
a3a674d15b
Use now more generic remoteConfig in a couple places that built
non-annex config settings manually before.
That was added back in 2013 commit 2af652e1b8
and I'm a bit unclear about the reasons.
It seemed that, at the time, receive.denyNonFastforwards=true, which is
the default in a repo created by git init --shared --bare (but not
without --shared), which the assistant did, caused problems syncing.
But even at the time the bug report showed an error message clearly
explaining that it was a non-fast-forward push being denied.
I tried it with the current version, and since git-annex sync pulls
from the bare repo and merges, it pushes a fast-forward. So there's no
failure to push. (There could be one if another push happened after the
pull, but you'd want it to fail then presumably.)
I'm not 100% sure what changed to make it not be a problem, but I know
I've seen this message in many circumstances and I can't ever recall it
having anything to do with any issue that prevented a push.
Based on doc/forum/non_fast_forward_error_with_git_annex_sync.mdwn,
which showed the problem when syncing from a direct mode repo,
and on doc/forum/receiving_indirect_renames_on_direct_repo___63__/comment_3_0246fff6c7c75f6be45bd257ec3872a5._comment
which seems to show the problem was actually a problem pulling,
I think there's a good chance that the problem actually involved direct
mode.
* Added sync --only-annex, which syncs the git-annex branch and annexed
content but leaves managing the other git branches up to you.
* Added annex.synconlyannex git config setting, which can also be set with
git-annex config to configure sync in all clones of the repo.
Use case is then the user has their own git workflow, and wants to use
git-annex without disrupting that, so they sync --only-annex to get the
git-annex stuff in sync in addition to their usual git workflow.
When annex.synconlyannex is set, --not-only-annex can be used to override
it.
It's not entirely clear what --only-annex --commit or --only-annex
--push should do, and I left that combination not documented because I
don't know if I might want to change the current behavior, which is that
such options do not override the --only-annex. My gut feeling is that
there is no good reasons to use such combinations; if you want to use
your own git workflow, you'll be doing your own committing and pulling
and pushing.
A subtle question is, how should import/export special remotes be handled?
Importing updates their remote tracking branch and merges it into master.
If --only-annex prevented that git branch stuff, then it would prevent
exporting to the special remote, in the case where it has changes that
were not imported yet, because there would be a unresolved conflict.
I decided that it's best to treat the fact that there's a remote tracking
branch for import/export as an implementation detail in this case. The more
important thing is that an import/export special remote is entirely annexed
content, and so it makes a lot of sense that --only-annex will still sync
with it.
Fix support for repositories tuned with annex.tune.branchhash1=true,
including --all not working and git-annex log not displaying anything for
annexed files.
fsck --from remote: Fix a concurrency bug that could make it incorrectly
detect that content in the remote is corrupt, and remove it, resulting in
data loss.
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.
The git add behavior changes could be avoided if it turns out to be
really annoying, but then it would need to behave the old way when
annex.dotfiles=false and the new way when annex.dotfiles=true. I'd
rather not have the config option result in such divergent behavior as
`git annex add .` skipping a dotfile (old) vs adding to annex (new).
Note that the assistant always adds dotfiles to the annex.
This is surprising, but not new behavior. Might be worth making it also
honor annex.dotfiles, but I wonder if perhaps some user somewhere uses
it and keeps large files in a directory that happens to begin with a
dot. Since dotfiles and dotdirs are a unix culture thing, and the
assistant users may not be part of that culture, it seems best to keep
its current behavior for now.
* 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.)
