Using adjusted/unlocked/master made lots of git stuff dealing with "master"
complain that it was ambiguous. This new appoach is more like view branch
names, and shows the adjustment right there in the branch display even if
only the basename of the branch is shown.
There's a race here, but entering an adjusted branch for the first time is
not something to do when a commit is being made at the same time. Although,
may want to prevent the assistant from committing while entering the
adjusted branch.
So, it will pull and push the original branch, not the adjusted one.
And, for merging, it will use updateAdjustedBranch (not implemented yet).
Note that remaining uses of Git.Branch.current need to be checked too;
for things that should act on the original branch, and not the adjusted
branch.
"git annex adjust" may be a temporary interface, but works for a proof of
concept.
It is pretty fast at creating the adjusted branch. The main overhead is
injecting pointer files. It might be worth optimising that by reusing the
symlink target as the pointer file content. When I tried to do that,
the problem was that the clean filter doesn't use that same format, and so
git thought files had changed. Could be dealt with, perhaps make the clean
filter use symlink format for pointer files when on an adjusted branch?
But the real overhead is in checking out the branch, when git runs the
smudge filter once per file. That is perhaps too slow to be usable,
although it may only affect initial checkout of the branch, and not
updates. TBD.
* add, addurl, import, importfeed: When in a v6 repository on a crippled
filesystem, add files unlocked.
* annex.addunlocked: New configuration setting, makes files always be
added unlocked. (v6 only)
The problem with having the slashes unescaped is, it broke parsing, since
the parser takes the filename to get the part containing the key.
That particularly affected URL keys.
This makes the format be the same as symlinks point to, which keeps things
simple.
Existing pointer files will continue to work ok.
Before, the call to mkProgressUpdater created the directory as a
side-effect, but since that ignored failure to create it, this led to
a "does not exist" exception when the transfer lock file was created,
rather than a permissions error.
So, make sure the directory exists before trying to lock the file in it.
When a PermissionDenied exception is caught, skip making the transfer lock.
This lets downloads from readonly remotes happen.
If an upload is being tried, and the lock file can't be written due to
permissions, then probably the actual transfer will fail for the same
reason, so I think it's ok that it continues w/o taking the lock in that
case.
