This relicates git's behavior. It adds a few stat calls for the command
line parameters, so there is some minor slowdown, but even with thousands
of parameters it will not be very noticable, and git does the same statting
in similar circumstances.
Note that this does not prevent eg "git annex add symlink"; the symlink
will be added to git as usual. And "git annex find symlink" will silently
list nothing as well. It's only "symlink/foo" or "subdir/symlink/foo" that
triggers the warning.

Also, truncate filenames provided by other remotes if they're too long,
when --preserve-filename is not used. That seems to have been omitted
before by accident.
I run haddock with `cabal haddock --executables`. It fails with:
Types/Remote.hs:271:17: error: parse error on input ‘->’
Apparently haddock does not like to find haddock blocks outside of
declarations? In any case, this patch makes these type of errors go
away.
Afterwards, I see errors like these, that need to be investigated as
a next step:
haddock: internal error: internal: extractDecl
CallStack (from HasCallStack):
error, called at utils/haddock/haddock-api/src/Haddock/Interface/Create.hs:1116:12 in main:Haddock.Interface.Create
* addurl --preserve-filename: New option, uses server-provided filename
without any sanitization, but with some security checking.
Not yet implemented for remotes other than the web.
* addurl, importfeed: Avoid adding filenames with leading '.', instead
it will be replaced with '_'.
This might be considered a security fix, but a CVE seems unwattanted.
It was possible for addurl to create a dotfile, which could change
behavior of some program. It was also possible for a web server to say
the file name was ".git" or "foo/.git". That would not overrwrite the
.git directory, but would cause addurl to fail; of course git won't
add "foo/.git".
sanitizeFilePath is too opinionated to remain in Utility, so moved it.
The changes to mkSafeFilePath are because it used sanitizeFilePath.
In particular:
isDrive will never succeed, because "c:" gets munged to "c_"
".." gets sanitized now
".git" gets sanitized now
It will never be null, because sanitizeFilePath keeps the length
the same, and splitDirectories never returns a null path.
Also, on the off chance a web server suggests a filename of "",
ignore that, rather than trying to save to such a filename, which would
fail in some way.
git-lfs repos that encrypt the annexed content but not the git repo only
need --force passed to initremote, allow enableremote and autoenable of
such remotes without forcing again.
Needing --force again particularly made autoenable of such a repo not work.
And once such a repo has been set up, it seems a second --force when
enabling it elsewhere has little added value. It does tell the user about
the possibly insecure configuration, but if the git repo has already been
pushed to that remote in the clear, data has already been exposed. The goal
of that --force was not to prevent every situation where such an exposure
can happen -- anyone who sets up a public git repo and pushes to it will
expose things similarly and git-annex is not involved. Instead, the purpose
of the --force is to point out to the user that they're asking for a
configuration where encryption is inconsistently applied.
To use S3 Signature Version 4. Some S3 services seem to require v4, while
others may only support v2, which remains the default.
I'm also not sure if v4 works correctly in all cases, there is this
upstream bug report: https://github.com/aristidb/aws/issues/262
I've only tested it against the default S3 endpoint.
37b42e72e7 made it catch exceptions but
thought they were unlikely to be useful to display, which may be right when
a git command fails, but not in the case yoh found.
Now the warning gets displayed, which is better than an arcane git error.
The warning is still kind of ugly, especially when the pull later in the
sync will clear up what it warns about. But, this is an unusual situation
not likely to happen, and if there is no remote to pull from, the warning
message is needed or the sync will seem to succeed despite not merging the
synced master branch.
Would still be better if it could merge the synced master branch in this
situation, making an empty commit to master to do it seems wrong, and
otherwise it would need a whole separate code path, and would bypass using
git merge in favor of say, setting master to the syned branch. Which would
bypass git configs like arguably merge.ff and certianly
merge.verifySignatures. So don't want to do that.
Extensions got renamed.
Default-Language is required. I had to put Haskell98 because there are
subtle differences between 98 and 2010 and git-annex has always been
built with the default, which was 98 when there was a default. I don't
know how to establish that git-annex will behave the same under 2010.
