Yesterday's SHA1 collision attack could be used to generate eg:
SHA256-sfoo--whatever.good
SHA256-sfoo--whatever.bad
Such that they collide. A repository with the good one could have the
bad one swapped in and signed commits would still verify.
I've already mitigated this.
I am not happy that I had to put backend-specific code in file2key. But
it would be very difficult to avoid this layering violation.
Most of the time, when parsing a Key from a symlink target, git-annex
never looks up its Backend at all, so adding this check to a method of
the Backend object would not work.
The Key could be made to contain the appropriate
Backend, but since Backend is parameterized on an "a" that is fixed to
the Annex monad later, that would need Key to change to "Key a".
The only way to clean this up that I can see would be to have the Key
contain a LowlevelBackend, and put the validation in LowlevelBackend.
Perhaps later, but that would be an extensive change, so let's not do
it in this commit which may want to cherry-pick to backports.

* Run curl with -S, so HTTP errors are displayed, even when
it's otherwise silent.
* When downloading in --json or --quiet mode, use curl in preference
to wget, since curl is able to display only errors to stderr, unlike
wget.
This does mean that downloadQuiet is only silent on stdout, not necessarily
on stderr, which affects a couple other calls of it. For example,
downloading the .git/config of a http remote may show an error message now,
perhaps with slightly suboptimal formatting due to other output.
This adds one extra line of output when a download is successful,
after the progress bar. I don't much like that, but wget does not provide a
way to show HTTP errors without it.

... to avoid it consuming stdin that it shouldn't.
This fixes git-annex-checkpresentkey --batch remote, which didn't output
results for all keys passed into it.
Other git-annex commands that communicate with a remote over ssh may also
have been consuming stdin that they shouldn't have, which could have
impacted using them in eg, shell scripts. For example, a shell script
reading files from stdin and passing them to git annex drop would be
impacted by this bug, whenever git annex drop ran git-annex-shell
checkpresent, it would consume part/all of the stdin that the shell script
was supposed to consume.
Fixed by adding a ConsumeStdin parameter to Annex.Ssh.sshOptions, which
is used throughout git-annex to run ssh (in order for ssh connection
caching to work). Every call site was checked to see if it used
CreatePipe for stdin, and if not was marked NoConsumeStdin.
At first I wanted to make it go ahead and merge into the newborn branch,
so made it use Git.Branch.currentUnsafe to get the current branch. But that
failed:
fatal: ambiguous argument 'refs/heads/master..refs/heads/synced/master':
unknown revision or path not in the working tree.
A whole nother code path to handle merging into newborn branches seemed
excessive, so went with displaying a warning and propigating failure
status.

The check was broken in two ways.. First, nowhere did it error out when
checkUUIDFile found a different UUID already in the file. Instead,
it overwrote the uuid file.
And, checkUUIDFile's implementation was for some reason always failing with
a ConnectionClosed exception. Apparently something to do with using two
different runResourceT's and a response getting GCed inbetween. I'm pretty
sure that used to work, but changed to a more obviously correct
implementation.

Probing for hard link support in the pid locking code is redundant since
git-annex init already probes that. But, it didn't seem worth threading
that data through; the pid locking code runs at most once per git-annex
process, and only on unusual filesystems. Optimising a single hard link
and unlink isn't worth it.

Git does not provide a switch to find out where this directory is, and
while the git-init man page says it will always be in
/usr/share/git-core/templates, that's not the case on OSX with git
installed from homebrew. So, I used a hack taking the --man-path and
constructing a path from that. Works on both Debian and OSX at least.
This is the same as running git annex reinject --known, followed by
git-annex import. The advantage to having it in one command is that it
only has to hash each file once; the two commands have to
hash the imported files a second time.
This commit was sponsored by Shane-o on Patreon.
import: --deduplicate and --skip-duplicates were implemented inneficiently;
they unncessarily hashed each file twice. They have been improved to only
hash once.
The new approach is to lock down (minimally) and hash files, and then
reuse that information when importing them.
This was rather tricky, especially in detecting changes to files while
they are being imported.
The output of import changed slightly. While before it silently skipped
over files with eg --skip-duplicates, now it shows each file as it starts
to act on it. Since every file is hashed first thing, it would otherwise
not be clear what file import is chewing on. (Actually, it wasn't clear
before when any of the duplicates switches were used.)
This commit was sponsored by Alexander Thompson on Patreon.
Before, only content known to be present somewhere was considered a
duplicate. Now, any content that has been annexed before will be considered
a duplicate, even if all annexed copies of the data have been lost.
Note that --clean-duplicates and --deduplicate still check numcopies,
so won't delete duplicate files unless there's an annexed copy.
This makes import use the same method as reinject --known.
The man page already said that duplicate meant "its content is either
present in the local repository already, or git-annex knows of another
repository that contains it, or it was present in the annex before but has
been removed now". So, this is really only bringing the implementation into
line with the man page.

Wormhole pairing will start to provide an appid to wormhole on 2021-12-31.
An appid can't be provided now because Debian stable is going to ship a
older version of git-annex that does not provide an appid. Assumption is
that by 2021-12-31, this version of git-annex will be shipped in a Debian
stable release. If that turns out to not be the case, this change will need
to be cherry-picked into the git-annex in Debian stable, or its wormhole
pairing will break.

This may become the default at some point in the future.
As well as being configuable by git config, it can be configured by
git-annex config to control the default behavior in all clones of a
repository.
Had to add a separate --no-content switch to we can tell if it's been
explicitly set, and should override annex.synccontent. If --content was the
default, this complication would not be necessary.

... to control the default behavior in all clones of a repository.
This includes a new Configurable data type, so the GitConfig type indicates
which values can be configured this way.
The implementation should be quite efficient; the config log is only read
once, and only when a Configurable value has not already been set by
git-config.
Indeed, it would be nice in the future to extend this, so that git-config
is itself only read on demand. Some commands may not need to look at the
git configuration at all.

Turns out that Data.List.Utils.split is slow and makes a lot of

As well as being an optimisation, this helps move toward eliminating use of
missingh.
(Data.List.Split.splitOn is nearly as slow as Data.List.Utils.split and
allocates even more.)
I have not benchmarked the effect on git-annex, but would not be surprised
to see some parsing of eg, large streams from git commands run twice as
fast, and possibly in less memory.

This way we know that after enable-tor, the tor hidden service is fully
published and working, and so there should be no problems with it at
pairing time.
It has to start up its own temporary listener on the hidden service. It
would be nice to have it start the remotedaemon running, so that extra
step is not needed afterwards. But, there may already be a remotedaemon
running, in communication with the assistant and we don't want to start
another one. I thought about trying to HUP any running remotedaemon, but
Windows does not make it easy to do that. In any case, having the user
start the remotedaemon themselves lets them know it needs to be running
to serve the hidden service.

weasel explained that apparmor limits on what files tor can read do not
apply to sockets (because they're not files). And apparently the
problems I was seeing with hidden services not being accessible had to
do with onion address propigation and not the location of the socket

remotedaemon looks up the HiddenServicePort in torrc, so if it was
previously configured with the socket in /etc, that will still work.

On second thought, this was an overcomplication of what should be the
lowest-level primitive. Let's build bi-directional links at the pairing
level with eg magic wormhole.
Both the local and remote git repositories get remotes added
pointing at one-another.
Makes pairing twice as easy!
Security: The new LINK command in the protocol can be sent repeatedly,
but only by a peer who has authenticated with us. So, it's entirely safe to
add a link back to that peer, or to some other peer it knows about.
Anything we receive over such a link, the peer could send us over the
current connection.
There is some risk of being flooded with LINKs, and adding too many
remotes. To guard against that, there's a hard cap on the number of remotes
that can be set up this way. This will only be a problem if setting up
large p2p networks that have exceptional interconnectedness.
A new, dedicated authtoken is created when sending LINK.
This also allows, in theory, using a p2p network like tor, to learn about
links on other networks, like telehash.

Revert ServerAliveInterval change in 6.20161111, which caused problems
with too many old versions of ssh and unusual ssh configurations.
It should have not been needed anyway since ssh is supposted to
have TCPKeepAlive enabled by default.
1 microsecond delay is ugly.. but, maintaining an queue of a list of timestamps
and taking a new one from the queue each time around, or maintaining a timestamp
counter, would probably be slower.
The attacker could just send a very lot of data, with no \n and it would
all be buffered in memory until the kernel killed git-annex or perhaps OOM
killed some other more valuable process.
This is a low impact security hole, only affecting communication between
local git-annex and git-annex-shell on the remote system. (With either
able to be the attacker). Only those with the right ssh key can do it. And,
there are probably lots of ways to construct git repositories that make git
use a lot of memory in various ways, which would have similar impact as
this attack.
The fix in P2P/IO.hs would have been higher impact, if it had made it to a
released version, since it would have allowed DOSing the tor hidden
service without needing to authenticate.
(The LockContent and NotifyChanges instances may not be really
exploitable; since the line is read and ignored, it probably gets read
lazily and does not end up staying buffered in memory.)
Would have liked to make the Parser parse the file and key pairs, but it

ghc 8 added backtraces on uncaught errors. This is great, but git-annex was

used to use error, so had a backtrace.

The Makefile was putting them in git-annex.linux/i18n/i18n, and so I18NPATH
did not point to the files. I think that on close enough to Debian systems,
localedef then fell back to using the system-wide locale files, while on
other systems it would fail to generate locales.
So that stalled transfers will be noticed within about 3 minutes,
even if TCPKeepAlive is disabled or doesn't work.
Rather than setting with -o, use -F with another config file,
so that any settings in ~/.ssh/config or /etc/ssh/ssh_config overrides this.
If a transfer fails for some reason, but some data managed to be sent, the
transfer will be retried. (The assistant already did this.)
Possible impacts:
* More ssh prompts if ssh needs to prompt for a password to connect to a
host, or is prompting about some other problem like a ssh key mismatch.
* More data transfer due to retrying, epecially when a remote does not
support resuming a transfer.
In the worst case, a lot of data will be transferred but it fails before
the end, and then all that data gets transferred again plus one byte more;
repeat until it manages to get the whole file.

The use of runWriter in scanUnlockedFiles broke due to this change;
it failed with blocked indefinitely in mvar, because the database write
handle was taken while linkFromAnnex needed to also write to it (to update
the inode cache). So, switched to using a separate runWriter for each call
to addAssociatedFileFast. A little less efficient, but not greatly; the
writes should all still be cached.
In the case where the pointer file is in place, and not the content
of the object, lock's performNew was called with filemodified=True,
which caused it to try to repopulate the object from an unmodified
associated file, of which there were none. So, the content of the object
got thrown away incorrectly. This was the cause (although not the root
cause) of data loss in https://github.com/datalad/datalad/issues/1020
The same problem could also occur when the work tree file is modified,
but the object is not, and lock is called with --force. Added a test case
for this, since it's excercising the same code path and is easier to set up
than the problem above.
Note that this only occurred when the keys database did not have an inode
cache recorded for the annex object. Normally, the annex object would be in
there, but there are of course circumstances where the inode cache is out
of sync with reality, since it's only a cache.
Fixed by checking if the object is unmodified; if so we don't need to
try to repopulate it. This does add an additional checksum to the unlock
path, but it's already checksumming the worktree file in another case,
so it doesn't slow it down overall.
Further investigation found a similar problem occurred when smudge --clean
is called on a file and the inode cache is not populated. cleanOldKeys
deleted the unmodified old object file in this case. This was also
fixed by checking if the object is unmodified.
In general, use of getInodeCaches and sameInodeCache is potentially
dangerous if the inode cache has not gotten populated for some reason.
Better to use isUnmodified. I breifly auited other places that check the
inode cache, and did not see any immediate problems, but it would be easy
to miss this kind of problem.
The modification flag was not being set when making modifications deep
in a tree, so parent trees were not updated to contain the modified tree.

Generally, any use of catKey was a potential problem.
Fix by using git cat-file --batch-check to check size before catting.
This adds another git batch process, which is included in the CatFileHandle

There could be performance impact, anywhere catKey is used. Particularly
likely to affect adjusted branch generation speed, and operations on
unlocked files in v6 mode. Hopefully since the --batch-check and
--batch read the same data, disk buffering will avoid most overhead.
Leaving only the overhead of talking to the process over the pipe and
whatever computation --batch-check needs to do.

Currently only done for utf-8 locales because the charset can easily be
told for those. Other locales don't include the charset in their name.
The locale definition is generated under git-annex.linux/locales.
So, this only works if the user can write there.
If locale generation fails for any reason, it's silently skipped.
The git-annex-standalone.deb installs the bundle under /usr, so this locale
generation won't work for non-root users.
Version mismatches between the system locale-archive and the glibc in the
bundle have been observed to cause git crashes.
Unfortunately, this causes locales to not be used in the linux standalone
bundle, as was the case until version 6.20160419.
glibc hardcodes the path to /usr/lib/locale/locale-archive and does not
let an environment variable cause a different locale-archive file to be used.
The only other option to include locales in the bundle would be to include
exploded locale definition directories in the bundle for a number of
locales, generated by localedef. But these take at least 300 kb per locale,
and there are a great many locales; it would be hundreds of megabytes to
include them all.
(Hmm, we could include localdef in the bundle, and check LANG in runshell
and compile the locale directories on the fly. This would need
/usr/share/i18n/ and /usr/lib/locale-archive to be included in the bundle.
It's.. doable.)
I know this is going to once again cause users of the bundle to complain
that eg, ls doesn't show their unicode filenames right. Better than strange
crashes though.
Multiple external special remote processes for the same remote will be
started as needed when using -J.
This should not beak any existing external special remotes, because running
multiple git-annex commands at the same time could already start multiple
processes for the same external special remotes.
This sped up git annex find --not --in web from 6.64s to 5.69s.
The optimised parser is probably more like 50% faster than the general one
it replaced.
Speeds up commands like "git-annex find --in remote" by over 50%.
Profiling showed that adjustGitEnv was 21% of the time and 37% of the
allocations of that command. It copied the environment each time with
getEnvironment.
The only repeated use of adjustGitEnv is in withIndexFile, which tends to
be run at least once per file. So, it was optimised by keeping a cache of
the environment, which can be reused.
There could be other better ways to optimise this. Maybe get the while
environment once at startup. But, then it would have to be serialized back
out each time running a child process, so I doubt that would be a net win.
It might be better to cache a version of the environment that is
pre-modified to use .git-annex/index. But, profiling doesn't show that
modifying the enviroment is taking any significant time.
key2file and file2key were top cost centers according to profiling.
The repeated use of replace was not efficient. This new approach is quite a
lot more efficient.

In the case of git-annex sync, using a fixed git-annex with an old unfixed
one will mean they use different sync branches for a deep branch, and so
they may stop syncing until the old one is upgraded. However, that's only
a problem when syncing between repositories without going via a central
bare repository. Added a warning about this to the CHANGELOG, but it's
probably not going to affect many people at all.

transfers from the same remote, but it was easier, and seems more useful,
to not have the same remote requirement.

Use nextRandom to generate the random UUID, rather than using randomIO.
This gets fixes for the following two bugs in the uuid library.
However, this did not impact git-annex much, so a hard depedency has

"v4 UUIDs are not that random"
This doesn't greatly affect git-annex, because even with only
2^64 possible UUIDs, the chance that two git-annex repositories
that are clones of the same git repo get the same UUID is miniscule.
And, git-annex generates only one UUID per run, so preducting
subsequent UUIDs is not a problem.

metadata --json output format has changed, adding a inner json object
named "fields" which contains only the fields and their values.
This should be easier to parse than the old format, which mixed up
metadata fields with other keys in the json object.
Any consumers of the old format will need to be updated.
This adds a dependency on unordered-containers for parsing MetaData
from JSON, but it's a free dependency; aeson pulls in that library.

* git-annex.cabal: Temporarily limit to http-conduit <2.2.0
since aws 0.14.0 is not compatible with the newer version.
* git-annex.cabal: Temporarily limit to persistent <2.5
since esqueleto 2.4.3 is not compatible with the newer version.
Added --branch option to copy, drop, fsck, get, metadata, mirror, move, and
whereis commands. This option makes git-annex operate on files that are
included in a specified branch (or other treeish).
The names of the files from the branch that are being operated on are not
displayed yet; only the keys. Displaying the filenames will need changes
to every affected command.
Also, note that --branch can be specified repeatedly. This is not really
documented, but seemed worth supporting, especially since we may later want
the ability to operate on all branches matching a refspec. However, when
operating on two branches that contain the same key, that key will be
operated on twice.
Ignore exceptions when getting the cost and availability for the remote,
and return sane defaults. These defaults are not cached, so if a special
remote program has a transient problem, it will re-query it later.
This bug caused broken tree objects to get built by a later git annex sync.
This is a somewhat unlikely but not impossible situation, and the test
suite's union_merge_regression test tickled it when it was run on FAT.
I noticed move --to failing when there was no disk space. The file was sent
to the remote, but it crashed before it could be dropped locally. This
could fix that.
Added guard in Annex.Transfer to prevent this problem at a deeper level.
I'm unhappy ith NoUUID, but having Maybe UUID instead wouldn't help either
if nothing checked that there was a UUID. Since there legitimately need to
be Remotes that do not have a UUID, I can't see a way to fix it at the type
level, short making there be two separate types of Remotes.
This actually runs faster than building the man pages from the makefile
did. But the main purpose is to let Setup.hs import Build.Mans and so not
need the makefile.
This fixes strange displays in some cases, including whereis showing
many duplicate locations, and showing more total copies than actually
exist.
It's unknown if that lead to data loss when eg, dropping. At the moment,
it seems unlikely it could, since the UUID with \r's appended is not the
same as a UUID without, and so no remote matches it.
It's also unknown if \r's can leak in on windows, perhaps when merging the
git-annex branch.
The tarball on hackage will include only the files needed for cabal install;
it is NOT the full git-annex source tree. While it's totally obnoxious that
cabal files need every file listed out when basic wildcard support could
avoid hundreds of lines, and have to be maintained when files are added,
this does get the tarball size back down to 1 mb.
This also stops stack from complaining that it found modules not listed in
the cabal file.
debian/changelog, debian/NEWS, debian/copyright: Converted to symlinks
to CHANGELOG, NEWS, and COPYRIGHT, which used to symlink to these instead.
This avoids needing to include debian/ in the hackage tarball.
Setup.hs: Build man pages at install time using make and mdwn2man.
If it fails, which it probably will on windows, just skip installing
them.
