Commit 4bf7940d6b introduced this
problem, but was otherwise doing a good thing. Problem being
that fileRef "/foo" used to return ":./foo", which was actually wrong,
but as long as there was no foo in the local repository, catKey
could operate on it without crashing. After that fix though, fileRef
would return eg "../../foo", resulting in fileRef returning
":./../../foo", which will make git cat-file crash since that's
not a valid path in the repo.
Fix is simply to make fileRef detect paths outside the repo and return
Nothing. Then catKey can be skipped. This needed several bugfixes to
dirContains as well, in previous commits.
In Command.Smudge, this led to needing to check for Nothing. That case
should actually never happen, because the fileoutsiderepo check will
detect it earlier.

sync --content: Avoid a redundant checksum of a file that was
incrementally verified, when used on NTFS and perhaps other filesystems.
When sync has just gotten the content, it does not need to check inAnnex a
second time. On NTFS, for some reason the write of the inode cache after
it gets the content is not immediately able to be read, and with an
empty/non-matching inode cache due to that stale data, inAnnex falls back
to hashing the whole object to determine if it's present.

Disabling git-annex branch update for this command is
ok, because it does not use any information from the branch,
but only logs the location when it adds a key.

I first saw this getting with -J2 over ssh, but later saw it also
without the -J2. It was resuming, and the calulated unboundDelay was
many minutes. The first update of the meter jumped to some large value,
because of the resuming, and so it thought the BW was super fast.
Avoid by waiting until the second meter update.
Might be a good idea to also guard for the delay being many seconds
and avoid waiting. But how many? If BW is legitimately super fast, and a
remote happens to read more than a 32kb or so chunk at a time, it could
in theory download megabytes or gigabytes of data before the first meter
update. It would actually be appropriate then to delay for a long time,
if the desired BW was low. Could make up some numbers that are sane now,
but tech may improve.
(BTW, pleased to see bwlimit does work with -J. I had worried that
it might not, if the meter update happened in a different thread than
the downloading, but it's done in the same thread.)

New method is much better. Avoids unrestrained transfer at the beginning
(except for the first block. Keeps right at or a few kb/s below the
configured limit, with very little varation in the actual reported bandwidth.
Removed the /s part of the config as it's not needed.
Ready to merge.

Probably this fixes a reversion, but I don't know what version broke it.
This does use withOtherTmp for a temp file that could be quite large.
Though albeit a reflink copy that will not actually take up any space
as long as the file it was copied from still exists. So if the copy cow
succeeds but git-annex is interrupted just before that temp file gets
renamed into the usual .git/annex/tmp/ location, there is a risk that
the other temp directory ends up cluttered with a larger temp file than
later. It will eventually be cleaned up, and the changes of this being
a problem are small, so this seems like an acceptable thing to do.

Added annex.bwlimit and remote.name.annex-bwlimit config that works for git
remotes and many but not all special remotes.
This nearly works, at least for a git remote on the same disk. With it set
to 100kb/1s, the meter displays an actual bandwidth of 128 kb/s, with
occasional spikes to 160 kb/s. So it needs to delay just a bit longer...
I'm unsure why.
However, at the beginning a lot of data flows before it determines the
right bandwidth limit. A granularity of less than 1s would probably improve
that.
And, I don't know yet if it makes sense to have it be 100ks/1s rather than
100kb/s. Is there a situation where the user would want a larger
granularity? Does granulatity need to be configurable at all? I only used that
format for the config really in order to reuse an existing parser.
This can't support for external special remotes, or for ones that
themselves shell out to an external command. (Well, it could, but it
would involve pausing and resuming the child process tree, which seems
very hard to implement and very strange besides.) There could also be some
built-in special remotes that it still doesn't work for, due to them not
having a progress meter whose displays blocks the bandwidth using thread.
But I don't think there are actually any that run a separate thread for
downloads than the thread that displays the progress meter.

* When downloading urls fail, explain which urls failed for which
reasons.
* web: Avoid displaying a warning when downloading one url failed
but another url later succeeded.
Some other uses of downloadUrl use urls that are effectively internal use,
and should not all be displayed to the user on failure. Eg, Remote.Git
tries different urls where content could be located depending on how the
remote repo is set up. Exposing those urls to the user would lead to wild
goose chases. So had to parameterize it to control whether it displays urls
or not.
A side effect of this change is that when there are some youtube urls
and some regular urls, it will try regular urls first, even if the
youtube urls are listed first. This seems like an improvement if
anything, but in any case there's no defined order of urls that it's
supposed to use.

it would be a problem. See comment for analysis of this windows drive

This fixes a reversion caused by a99a84f342,
when git-annex init is run as root on a FAT filesystem mounted with
hdiutil on OSX. Such a mount point has file mode 777 for everything and
it cannot be changed. The existing crippled filesystem test tried to
write to a file after removing write bit, but that test does not run as
root (since root can write to unwritable files). So added a check of the
write permissions of the file, after attempting to remove them.

This is to track down what file in .git/annex/ is being written to via a
temp file when the repository is read-only.

And fail with an informative message.
I don't think ACLs can prevent removing the write bit, but I'm not sure,
so kept it mentioning them as a possibility.
Should git-annex lock also check if the write bits are able to be removed?
Maybe, but the case I know about with xattrs involves cp -a copying NFS
xattrs, and it's the copy of the file that is the problem. So when locking
a file, I guess it will not be the copy.

It would be better if the Arbitrary instance avoided generating impossible
filenames like "foo/c:bar", but proably this is the only place that splits
the file from the directory and then uses the file without the directory..
At least on the quickcheck properties.

This is a little bare bones but hopefully useful, some things that could
be improved:
1. Follow steps in order and replicate (I reconstructed off of my
success, so there may be inaccuracies or things I forgot)
2. Clarify correct ownership for directories & sockets
- enable-tor's sudo child will obtain the hostname so no access is
needed after that
- does it also create the tor sockety directory?
3. Remove unnecessary boilerplate
- can the hidden service dir be left with the NixOS default?
And that should be all the special remotes supporting it on linux now,
except for in the odd edge case here and there.

Except when configuration makes curl be used. It did not seem worth
trying to tail the file when curl is downloading.
But when an interrupted download is resumed, it does not read the whole
existing file to hash it. Same reason discussed in
commit 7eb3742e4b76d1d7a487c2c53bf25cda4ee5df43; that could take a long
time with no progress being displayed. And also there's an open http
request, which needs to be consumed; taking a long time to hash the file
might cause it to time out.
Also in passing implemented it for git and external special remotes when
downloading from the web. Several others like S3 are within striking
distance now as well.

Added fileRetriever', which will let the remaining special remotes
eventually also support incremental verify.
Sponsored-by: Dartmouth College's DANDI project
Simply feed each chunk in turn to the incremental verifier.
When resuming an interrupted retrieve, it does not do incremental
verification. That would need to read the file, up to the resume point,
and feed it to the incremental verifier. That seems easy to get wrong.
Also it would mean extra work done before the transfer can start. Which
would complicate displaying progress, and would perhaps not appear to the
user as if it was resuming from where it left off. Instead, in that
situation, return UnVerified, and let the verification be done in a
separate pass.
Granted, Annex.CopyFile does manage all that, but it's not complicated
by dealing with chunks too.
