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.
Values in AnnexRead can be read more efficiently, without MVar overhead.
Only a few things have been moved into there, and the performance
increase so far is not likely to be noticable.
This is groundwork for putting more stuff in there, particularly a value
that indicates if debugging is enabled.
The obvious next step is to change option parsing to not run in the
Annex monad to set values in AnnexState, and instead return a pure value
that gets stored in AnnexRead.
Not yet used, but allows getting the size of items in the tree fairly
cheaply.
I noticed that CmdLine.Seek uses ls-tree and the feeds the files into
another long-running process to check their size. That would be an
example of a place that might be sped up by using this. Although in that
particular case, it only needs to know the size of unlocked files, not
locked. And since enabling --long probably doubles the ls-tree runtime
or more, the overhead of using it there may outwweigh the benefit.
I don't think this was really intentional behavior. It may be that it was
useful to include it so it could be passed to rmurl, since without it rmurl
would not actually remove the url. Since that was changed earlier today,
now seems like a good time to clean up the display of these urls.

fsck: When --from is used in combination with --all or similar options, do
not verify required content, which can't be checked properly when operating
on keys.

unregisterurl: Fix a bug that caused an url to not be unregistered when it
is claimed by a special remote other than the web.
See commit f175d4cc90 for rationalle.
* rmurl: When youtube-dl was used for an url, it no longer needs to be
prefixed with "yt:" in order to be removed.
* rmurl: If an url is both used by the web and also claimed by another
special remote, fix a bug that caused the url to to not be removed.
The youtube-dl change is a consequence of how the bug fix is implemented.
But I also think it's the right thing to do. Consider that, before,
git-annex addurl $url followed by git-annex rmurl $url would not remove the
url in the case where youtube-dl was used. That was surprising behavior.
In the unlikely case where a special remote claims an url, and it's been
added using OtherDownloader, but it was also added already as a web url,
it seems better for rmurl to remove both than to arbitrarily remove only one.
And in the case the bug report was filed for, when an url was added as a
web url, but a special remote now claims it, that should not prevent rmurl
removing the web url.
Calling setUrlMissing lets other callers of it behave differently.
Probably the calls to it in eg, Remote.External and Remote.BitTorrent are
fine, since they don't mangle the url and just remove what was provided,
and the OtherDownloader form of a bittorrent url, respectively.
I suspect unregisterurl needs to have a similar change made to rmurl, for
similar reasons.
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.
import: When the previously exported tree contained a submodule,
preserve it in the imported tree so it does not get deleted.
The export exclude log, which was used for non-preferred content,
now also includes the submodules. Since the log format is git ls-tree
output, this does not break backwards compatibility.
It's not necessary to log location of GIT keys, because these files are
not annexed files and so git-annex will never need to get them.
This corresponds to code in Annex.Import that already checked before
updating the location log when handling deleted files.
Older versions of git-annex that used SHA1 keys for non-annexed files
also unncessarily updated the location log for them.
GIT keys still appear in the git-annex branch for content identifier
logs, so kept the documentation of them in backends.mdwn

This solves the problem that import of such files gets confused and
converts them back to annexed files.
The import code already used GIT keys internally when it determined a
file should not be annexed. So now when it sees a GIT key that export
used, it already does the right thing.
This also means that even older version of git-annex can import and will
do the right thing, once a fixed version has exported. Still, there may
be other complications around upgrades; still need to think it all
through.
Moved gitShaKey and keyGitSha from Key to Annex.Export since they're
only used for export/import.
Documented GIT keys in backends, since they do appear in the git-annex
branch now.

Added LinkType to ProvidedInfo, and unified MatchingKey with
ProvidedInfo. They're both used in the same way, so there was no real
reason to keep separate.
Note that addLocked and addUnlocked still set matchNeedsFileName,
because to handle MatchingFile, they do need it. However, they
don't use it when MatchingInfo is provided. This should be ok,
the --branch case will be able skip checking matchNeedsFileName,
since it will provide a filename in any case.
Implemented by generalizing registerurl. Without the implicit batch mode
of registerurl since that is only a backwards compatability thing
(see commit 1d1054faa6).
unannex, uninit: When an annexed file is modified, don't overwrite the
modified version with an older version from the annex
This commit was sponsored by Mark Reidenbach on Patreon.
When a git remote is configured with an absolute path, use that path,
rather than making it relative. If it's configured with a relative path,
use that.
Git.Construct.fromPath changed to preserve the path as-is,
rather than making it absolute. And Annex.new changed to not
convert the path to relative. Instead, Git.CurrentRepo.get
generates a relative path.
A few things that used fromAbsPath unncessarily were changed in passing to
use fromPath instead. I'm seeing fromAbsPath as a security check,
while before it was being used in some cases when the path was
known absolute already. It may be that fromAbsPath is not really needed,
but only git-annex-shell uses it now, and I'm not 100% sure that there's
not some input that would cause a relative path to be used, opening a
security hole, without the security check. So left it as-is.
Test suite passes and strace shows the configured remote url is used
unchanged in the path into it. I can't be 100% sure there's not some code
somewhere that takes an absolute path to the repo and converts it to
relative and uses it, but it seems pretty unlikely that the code paths used
for a git remote would call such code. One place I know of is gitAnnexLink,
but I'm pretty sure that git remotes never deal with annex symlinks. If
that did get called, it generates a path relative to cwd, which would have
been wrong before this change as well, when operating on a remote.
When annex.stalldetection is not enabled, and a likely stall is detected,
display a suggestion to enable it.
Note that the progress meter display is not taken down when displaying
the message, so it will display like this:
0% 8 B 0 B/s
Transfer seems to have stalled. To handle stalling transfers, configure annex.stalldetection
0% 10 B 0 B/s
Although of course if it's really stalled, it will never update
again after the message. Taking down the progress meter and starting
a new one doesn't seem too necessary given how unusual this is,
also this does help show the state it was at when it stalled.
Use of uninterruptibleCancel here is ok, the thread it's canceling
only does STM transactions and sleeps. The annex thread that gets
forked off is separate to avoid it being canceled, so that it
can be joined back at the end.
A module cycle required moving from dupState the precaching of the
remote list. Doing it at startConcurrency should cover all the cases
where the remote list is used in concurrent actions.

Missed this when implementing it because of the default case catching
the new constructor. So, removed that default case to make sure
future types of adjusted branches don't make the same mistake.
Complicated by git-annex addurl --fast which adds the file whose content
is not present, so it needs to stay unlocked when on such a branch.

34a535ebea broke the test suite.
Getting a file started failing in one case, because the annex object did
not have its inode cached, so was not trusted to be unmodified.
This adds something very similar to what was added to linkAnnex
in commit 2e9341a47d -- if there are not
yet any inodes cached for a key, add the inode of the annex object when
adding the inode of the unlocked file.
Feels like this should be handled in a more principled way. How
do we know the addInodeCaches call in getMoveRaceRecovery just above
this change is currently correct? It doesn't add the annex object inode
cache. Ah well, maybe sometime when I've not had my entire evening eaten
by a reversion that the test suite caught as I was cooking dinner.
Avoids the smudge --clean filter failing because URL keys do not support
genKey. Instead the modified content will be added using the default
backend.
This commit was sponsored by Jochen Bartl on Patreon.
This avoids the smudge --clean filter failing on the URL keys.
git checkout runs the post-checkout hook, which runs smudge --update.
That populates all the pointer files, but it neglected to store their inode
caches in the keys db. With that done, and the keys db flushed before
smudge --clean gets run (by restagePointerFile), the isUnmodifiedCheap
check can tell the file is not modified, so will not try to re-ingest it,
which does not work with URL keys because they do not support genKey.
It also seems possible that the isUnmodifiedCheap was also failing for
non-URL keys, which would cause them to be re-ingested, leading to a lot of
extra work. I have not verified that, but don't see why it wouldn't have
happened. So this probably also speeds up checking out adjusted branches.

Configuring chunking and encryption for a git remote has no effect, so
skip testing those variants in the TestRemote call.
It would be better if TestRemote itself could do this, but it
doesn't seem possible there. There is no way to look at a Remote and
tell if it supports chunking or encryption.
Note that, while the test suite displays output as it it's testing
exporting, it actually skips doing anything for the tests when run on
the git remote. So at least does not waste time even though the output
is not ideal.

Since unconsidered use of trusted repositories can lead to data loss.
Trusted has always been this way, but it used to be acceptable for
git-annex to be set up so that data could be lost without using --force,
and most or all other ways that can happen have already been eliminated.

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.

* add: Significantly speed up adding lots of non-large files to git,
by disabling the annex smudge filter when running git add.
* add --force-small: Run git add rather than updating the index itself,
so any other smudge filters than the annex one that may be enabled will
be used.
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.
May actually work now.
Note that, importKey now has to add the size to the key if it's supposed
to have size. Remote.Directory relied on the importer adding the size,
which is no longer done, so it was changed; it was the only one.
This way, importKey does not need to behave differently between regular
and thirdpartypopulated imports.
These don't have importTree in their config, because they don't support
tree import, but they do still support import, and do not support export
or key/value modification.
