When a remote is configured to be readonly, don't allow changing what's
exported to it.
This was missed in the original export remote implementation, but it makes
sense for a readonly export remote to not be allowed to change.
~/.profile works for bash, but not all other login shells.
This setting PATH is a minor convenience for users, particuarly since
typing on android is so much harder. The usual linux standalone bundle
just expects the user to know how to add it to PATH. I don't want this
code to grow special cases for every possible login shell. So displaying a
message to the presumably minority who don't use bash seems like the best
choice.
Longer term, I'd hope termux gets some way to set an environment variable
for all login shells. Systems using PAM can, via ~/.pam_environment. Or
alternatively, add a git-annex package to termux, even if just an installer
package. I'd rather spend time on either of those than on making this minor
thing support more login shells.

* init: When the repository already has a description, don't change it.
* describe: When run with no description parameter it used to set
the description to "", now it will error out.
Fixes bug that caused git-annex to fail to add a file when another
git-annex process cleaned up the temp directory it was using.
Solution is just to push withOtherTmp out to a higher level, so that
the whole ingest process can be completed inside it.
But in the assistant, that was not practical to do, since withOtherTmp runs
in the Annex monad and the assistant does not. Worked around by introducing
a separate temp directory that only the assistant uses for lockdown.
Since only one assistant can run at a time, it's easy to clean up that
directory of old cruft at startup.
This is only done for correctness sake; I don't see any way that it
would have caused a problem here. The jlog file escaped withOtherTmp
so another process could swoop in and delete it, but the file is only
used as a buffer for a list of filenames, and its handle gets rewound
and they're read back out, which will still work even if it's already
been deleted.
The only reason I didn't just pre-delete the file and keep the handle
open is I'm not sure that works on all OS's (eg Windows). If there was
a problem that this fixed it might involve an OS that doesn't support
deleting an open file or something like that.
Fix reversion in last release that caused wrong tree to be written to
remote tracking branch after an export of a subtree.
The invariant "commitsha should have the treesha as its tree"
was not met due to a bug. Guarantee it's met by catting the commitsha
to find its actual tree. A little bit slower, but this is not run often.
Fix bug that caused importing from a special remote to repeatedly download
unchanged files when multiple files in the remote have the same content.
Unfortunately, there's really no good way to remove a uniqueness constraint
from a sqlite database. The best that can be done is to make a new table
and copy the data over. But that would require using persistent's
migrations or raw sql, and I don't want to do either.
Instead, a sledgehammer approach: Renamed .git/annex/cid to
.git/annex/cids. When the new database doesn't exist, it will be populated
from the git-annex branch.
Noting deletes the old database. Don't want to delete it out from under
some long-running git-annex process that might be using it. It could
eventually be deleted. But this is such a new feature, probably few repos
have the database in any case.
protocol=https implies port=443 and
port=443 implies protocol=https
-- this was necessary because the existing configs set port=443, but
with a protocol setting, users will naturally want to use it, and then
there's no need for them to supply the default https port. So we keep
back-compat, add a nicer way to enable https, and also add support for
non-standard https ports.
In particular, when two files had the same content, and one was unlocked
and modified, with annex.thin that can corrupt the content of the
annex object, and so fsck on the other file should detect that.
getKeyStatus was relying on Database.Keys.getAssociatedFiles to tell
when a file is unlocked, but that can false positive because the
database can list old associated files.
Instead, separate out the case of unlocked object which has multiple
hardlinks when annex.thin is in use.
To support filenames starting with dashes.
To update the config of existing repositories, you can re-run git-annex init.
Perhaps it should check every time for the old config and update it, but
that has several problems:
- read-only repos
- unexpected commands like `git annex find` changing git configs
might be surprising behavior
Since filenames starting with dashes are not super common and the user can
re-init easily enough if their repo needs fixed, I went for the simplest
fix.
xporting files with '#' or '?' in their name won't work because urls get
truncated on those. Fail in a better way in this case, and avoid failing
when removing such files from the export, so after the user has renamed the
problem files the export will succeed.
Because when git-annex lacks S3 version IDs for files stored in the bucket,
deleting them would cause data loss.
Also because git-annex is not able to download unversioned objects from a bucket
when versioning=yes.
This also prevents setting versioning=no. While that would perhaps be
possible to do safely, it would add complexity, and would mean that if
the user accidentially did enableremote versioning=no, they would not be
able to undo it.

However, rsync still won't work with 64 bit git and
this is still not the documented way to install it.
So, if both 64 and 32 are installed, go with 32.
And if neither git can be found, default to 32.
This fixes a bug with the numcopies counting when using sync --content.
It did not always pass the local repo uuid to handleDropsFrom, and so the
numcopies counting was off by one, and unwanted local content would only be
dropped when there were numcopies+1 remote copies.
Also, support dropping local content that has reached an
exporttree remote that is not untrusted (currently only S3 remotes
with versioning).
* Fix bug upgrading from direct mode to v7: when files in the repository
were already committed as v7 unlocked files elsewhere, and the
content was present in the direct mode repository, the annexed files
got their full content checked into git.
* Fix bug that caused v7 unlocked files in a direct mode repository
to get locked when committing.

webdav: When initializing, avoid trying to make a directory at the top of

dropunused: When an unused object file has gotten modified, eg due to

When a command is operating on multiple files and there's an error with
one, try harder to continue to the rest. (As was already done for many
types of errors including IO errors.)
This handles cases like lockContentForRemoval throwing an exception when
the content is already locked. Just because a drop of one file fails, does
not mean it shouldn't go on to try to drop other files.
I looked over uses of `giveup` in Command/*; there are too many to check
them all extensively, but none stood out as being problems that should let
one commandAction stop running other commandActions. Worst case, something
bad will happen and rather than stopping right away with an error,
git-annex will display multiple errors as it fails over and over on each
file. I don't think I ever really intended `error`/`giveup` to stop other
commandActions; this was a relic of old confusion over haskell exception
handling.
Test suite passes.

When an export conflict prevents accessing a special remote, be clearer
about what the problem is and how to resolve it.

Don't much like that there's no way to distinguish between having the whole
content and having an old version of the file that's bigger, but of course
resuming a http transfer can always yield the wrong result if the file on
the http server is changing, and git-annex will detect that when it
verifies the downloaded content.

Fix bash completion of "git annex" to propertly handle files with spaces

Finishes the start made in 983c9d5a53, by
handling the case where `transfer` fails for some other reason, and so the
ReadContent callback does not get run. I don't know of a case where
`transfer` does fail other than the locking dealt with in that commit, but
it's good to have a guarantee.
StoreContent and StoreContentTo had a similar problem.
Things like `getViaTmp` may decide not to run the transfer action.
And `transfer` could certianly fail, if another transfer of the same
object was in progress. (Or a different object when annex.pidlock is set.)
If the transfer action was not run, the content of the object would
not all get consumed, and so would get interpreted as protocol commands,
which would not go well.
My approach to fixing all of these things is to set a TVar only
once all the data in the transfer is known to have been read/written.
This way the internals of `transfer`, `getViaTmp` etc don't matter.
So in ReadContent, it checks if the transfer completed.
If not, as long as it didn't throw an exception, send empty and Invalid
data to the callback. On an exception the state of the protocol is unknown
so it has to raise ProtoFailureException and close the connection,
same as before.
In StoreContent, if the transfer did not complete
some portion of the DATA has been read, so the protocol is in an unknown
state and it has to close the conection as well.
(The ProtoFailureMessage used here matches the one in Annex.Transfer, which
is the most likely reason. Not ideal to duplicate it..)
StoreContent did not ever close the protocol connection before. So this is
a protocol change, but only in an exceptional circumstance, and it's not
going to break anything, because clients already need to deal with the
connection breaking at any point.
The way this new behavior looks (here origin has annex.pidlock = true so will
only accept one upload to it at a time):
git annex copy --to origin -J2
copy x (to origin...) ok
copy y (to origin...)
Lost connection (fd:25: hGetChar: end of file)

Fix hang when transferring the same objects to two different clients at the
same time. (Or when annex.pidlock is used, two different objects to the
same or different clients.)
Could also potentially occur if a client was downloading an object and
somehow lost connection but that git-annex-shell was still running and
holding the transfer lock.
This does not guarantee that, if `transfer` fails for some other reason,
a DATA response will be made.

I suspect this may be due to SQLITE_IOERR_SHORT_READ, but have not
verified.
I was able to reproduce it on Linux after running the test suite in a loop
for 1-3 hours until it failed.
The WAL mode entry change in 3963c5fcf5
may have hidden the problem I was seeing; I have not seen an ErrorIO
since then.
This is safe, because while the annex object ends up executable,
there were already at least two other cases where it ended up executable:
1. git add an an executable file
2. chmod +x of a a non-executable worktree file that was hard linked to the
annex object
After copy/hard link, it always fixes up the permissions to match the mode
of the worktree file, so when an executable annex object gets hard linked
to a non-executable worktree file, its execute bit gets removed.
Commit b7c8bf5274 already *said* it would do
this; I suspect the line of code I've removed was included in that commit
accidentially.
Also improves annex.thin documentation.

It was trying to git annex adjust when in a direct mode repo, and that
of course fails. What I don't understand though, is how the test suite
managed to work before, when it was clearly checking the wrong thing.
Since the right way to fix it was obvious, I have not bisected.

That could cause git-annex to get confused about whether a locked file's
content was present, when the object file got touched.
Unfortunately this means more work sometimes when annex.thin is set,
since it has to checksum the file to tell if it's still got the right
content.
Had to suppress output when inAnnex calls isUnmodified, otherwise
"(checksum...)" would be printed in places it ought not to be,
eg "git annex get" could turn out not need to get anything, and
so only display that.

* rmurl: Fix a case where removing the last url left git-annex thinking
content was still present in the web special remote.
* SETURLPRESENT, SETURIPRESENT, SETURLMISSING, and SETURIMISSING
used to update the presence information of the external special remote
that called them; this was not documented behavior and is no longer done.
Done by making setUrlPresent and setUrlMissing only update presence info
for the web, and only when the url is a web url. See the comment for
reasoning about why that's the right thing to do.
In AddUrl, had to make it update location tracking, to handle the
non-web-url case.
