Fix bug that made changes to a special remote sometimes be missed when
importing a tree from it. The diff import would miss when a change was
exported, then manually undone on the special remote (eg deleting a newly
exported file). A full import is needed to catch such changes.
After upgrading, any such missed changes will be included in the next
tree imported from a special remote. This happens because the previously
recorded content identifier tree does not have export information included,
so it is treated as invalid, and a full import is done.
Fixes reversion introduced in version 10.20230626, commit
40017089f2
Unfortunately, this does mean that after each export, the next import will
be a full import. Which can take significantly longer than the diff import
does, when there are a lot of files in the tree.
It would be better if exporting also update the content identifier tree.
However, I don't know if that can be done inexpensively. It would be future
optimisation work, in any case.
(That could only be done for an export that is run in the same
repository as the import. When an export is run in a different repository,
the export.log gets updated, and that propagates to the repository where
import is later run. At that point, a full import is done.)

Fix hang that could occur when using git-annex adjust on a branch with a
number of files greater than annex.queuesize. Or potentially other
commands.
When reconcileStaged is running, the database is being opened. But
restagePointerFiles closes the database, and later writes to it. So it will
deadlock if called by reconcileStaged.
The deadlock occurred when the git queue happened to be full, causing
adding a call to restagePointerFiles to it to flush the queue and
restagePointerFiles to run at the wrong time.
Fixed by making reconcileStaged, when it populates or depopulates a pointer
file, arrange for restagePointerFiles to be run as a cleanup action, rather
than from the git queue.
But, what if restagePointerFiles is already in the git queue before
reconcileStaged is run? If it adds anything else to the git queue, causing
the queue to flush, it would still deadlock. To avoid this hypothetical
situation, added a Annex.inreconcilestaged, and made restagePointerFiles
check it and not do anything.
Note that, I did consider the simpler approach of only running
restagePointerFiles as a cleanup action, rather than from the git queue.
But see commit 6a3bd283b8 for why it was made
to use the queue in the first place. I wanted to avoid tying this bug fix
to a behavior change.

Changing the type out from under an existing special remote exposes the
existing config to something that may interpret it wildly differently. As
seen in the bug report, this can even result in behavior that makes
git-annex say it's buggy. So prevent the user from doing this. --sameas is
the better way.

Made all uses of openFd and dup set the close-on-exec flag, with a few
exceptions when starting a git-annex daemon.
Made openFdWithMode be used everywhere, rather than openFd.
Adding a new parameter to it ensures I checked everything.
And will help to make sure this gets considered in the future when
opening fds.
In lockPidFile, the only thing that keeps the pid file locked, once
daemonize re-runs the command in a new session, is that the fd is
inherited.
In Utility.LogFile.redir, the new fd it dups to does not have the
close-on-exec flag set, because this is used to set up the stdout and
stderr fds, which need to be inherited by child processes.
Same in Assistant.startDaemon where the browser gets started with the
original stdout and stderr.
This does nothing about uses of openFile and similar!

This is the same as --not --in $remote, but easier to type. And the
documentation of --fast helps also document that drop can do extra work
when used without --fast.

This entirely removes Git.BuildVersion, which avoids the possibility that
git-annex will behave differently based on the version of git it was built
with, rather than the version it's used with.
Debian oldoldstable is the oldest version of git that git-annex needs to
support, since it's used in the amd64ancient build.
cabal configure will fail if the git version is too old.

p2p: Added --enable option, which can be used to enable P2P networks
provided by external commands git-annex-p2p-<netname>
Made git-annex p2p --enable tor behave the same as git-annex enable-tor,
to make tor a bit less of a special case. However, it canot be run as root,
since it cannot take the user id parameter.
When using the new generic P2P transport to open an outgoing connection
to a peer, this will hold the pid of the git-annex-p2p-<netname>
command.
closeConnection simply waits for it. Rather than relying on garbage
collection of the closed handles to close it.
In Remote.Helper.Ssh, connProcess is set to Nothing, even though there
is a similar process being used there. That code stores the pid in
OpenConnection instead, and handles waiting for it itself. A bit ugly,
but not worth cleaning up at this point, maybe later.
This is for p2p-annex:: urls that will use the new generic P2P
transport.
In addressCredsFile, threw in an url encoding of any non-alphanumeric
characters that are in the address. This is to avoid any possible path
traversal attacks via a p2p-annex:: url, since the address part of it
could contain any characters. And, went ahead and did the same url
encoding of tor-annex:: urls, even though tor onion addresses are all
alphanumerics, on the off chance that might avoid a similar problem.
(It does not seem likely enough to treat it as a security hole.)
This cleans up after the bug that was fixed in commit
6a9e923c74
Object files that were stored in the wrong location are rescued,
and after that any wrong location logs will be fixed by the usual fsck.
Used protectedOutput to set up a umask that makes the socket only
accessible by the current user.
Authentication is still needed when using this option unless it is combined
with --wideopen. It was just simpler to keep authentication separate from
this.
This allows for eg dir/user/repo structure. But also other layouts. It
still does not look for repositories that are nested inside other
repositories.
The check for symlinks is mostly to avoid cycles that would prevent
findRepos from returning. Eg, foo/bar/baz being a symlink to foo/bar.
If the directory is writable by someone else they can still race it and
get it to follow a symlink to some other directory. I don't think p2phttp
needs to worry about that kind of situation though, and I doubt it avoids
such problems when operating on files in a git-annex repository either.
As groundwork for making git-annex p2p support other P2P networks than
tor hidden services, when an AuthToken is not a TorAnnex value, but
something else (that will be added later), store the P2PAddress that it
will be used with along with the AuthToken. And in loadP2PAuthTokens,
only return AuthTokens for the specified P2PAddress.
See commit 2de27751d6 for some design work
that led to this.
Also, git-annex p2p --gen-addresses is changed to generate a separate
AuthToken for every P2P address. Rather than generating a single
AuthToke and using it for every one. When we have more than just tor,
this will be important for security, to avoid a compromise of one P2P
network exposing the AuthToken used for another network.
sync: Push the current branch first, rather than a synced branch, to better
support git forges (gitlab, gitea, forgejo, etc.) which use push-to-create
with the first pushed branch becoming the default branch.
With considerable complication to filter out warning message about
receive.denyCurrentBranch when pushing to a non-bare repository. Localization
may break it in the future, but it seems like the best way to handle this. See
my comments for the gory details.
Also fixes it in the graphviz map in some cases, where there is no
description for a repository.
And in json, use the remote name, never the description, since the field
is "remote" which is intended to be the git remote name.

Avoid using "name" for what git-annex otherwise refers to as a
description.
(For the remotes in the map, the "remote" field should be the remote
name, but there is a bug preventing it from being that.)

It was treating remote paths of a remote repo as if they were local paths,
and so trying to expand git directories and so forth on them. That led to
bad results, including a path like "foo.git" getting turned into
"foo.git.git"

Which is a per-remote version of the annex.web-options config.
Had to plumb RemoteGitConfig through to getUrlOptions. In cases where a
special remote does not use curl, there was no need to do that and I used
Nothing instead.
In the case of the addurl and importfeed commands, it seemed best to say
that running these commands is not using the web special remote per se,
so the config is not used for those commands.
requiredContentMap does not exclude dead repos. Usually this is not a
problem because it is used when we are operating on a repository, and in
that case, the repository is not dead (or if it is, the required content
configurations should still be used). But in the case of fsck, this made a
old required content config for a dead repository be warned about in a
situation where it is not a problem.
updatecluster, updateproxy: When a remote that has no annex-uuid is
configured as annex-cluster-node, warn and avoid writing bad data to the
git-annex branch.
The proxy.log and cluster.log end up unparseable when a NoUUID gets written
to them.
When writing doc/tips/computing_annexed_files.mdwn, I noticed
that a recompute --reproducible followed by a drop and a re-get did not
actually test if the file could be reproducible computed again.
Turns out that get and drop both operate on staged files. If there is an
unstaged modification in the work tree, that's ignored. Somewhat
surprisingly, other commands like info do operate on staged files. So
behavior is inconsistent, and fairly surprising really, when there are
unstaged modifications to files.
Probably this is rarely noticed because `git-annex add` is used to add a
new version of a file, and then it's staged. Or `git mv` is used to move
a file, rather than `mv` of a file over top of an existing file. So it's
uncommon to have an unstaged annexed file in a worktree.
It might be worth making things more consistent, but that's out of scope
for what I'm working on currently.
Also, I anticipate that supporting unlocked files with recompute will
require it to stage changes anyway.
So, make recompute stage the new version of the file.
I considered having recompute refuse to overwrite an existing staged
file. After all, whatever version was staged before will get lost when
the new version is staged over top of it. But, that's no different than
`git-annex addcomputed` being run with the name of an existing staged
file. Or `git-annex add` being run with a new file content when there is
an existing staged file. Or, for that matter, `git add` being ran with a
new content when there is an existing staged file.
Used by git-annex-compute-singularity to make addcomputed --fast work.
Also, simplified git-annex-compute-singularity; there is no need to hard
link the container into place. singularity does not care about the
extension of the container, so can just pass it the annex object file.
In this case, the compute program is run the same as if addcomputed --fast
were used, so it should succeed, without outputting a computed file.
computeInputsUnavailable is in ComputeState for simplicity, but it is
not serialized with the rest of the ComputeState.
