Ensure that each file has something written to it, even if the bytestring
chunk size is greater than the configured chunksize.
This means we may write a bit larger than the configured value, but only
when the configured value is very small; ie, < 8 kb.
Files are now written to a tmp directory in the remote, and once all
chunks are written, etc, it's moved into the final place atomically.
For now, checkpresent still checks every single chunk of a file, because
the old method could leave partially transferred files with some chunks
present and others not.
Both the directory and webdav special remotes used to have to buffer
the whole file contents before it could be decrypted, as they read
from chunks. Now the chunks are streamed through gpg with no buffering.
Wrote a better git remote name sanitizer. Git blows up on lots of weird
stuff, especially if it starts the remote name, but I managed to get
some common punctuation working.
MountWatcher can't do this, because it uses the session dbus,
and won't have access to the new DBUS_SESSION_BUS_ADDRESS if a new session
is started.
Bumped dbus library version, FD leak in it is fixed.
For now, when dbus goes away, the assistant keeps running but does not fall
back or reconnect. To do so needs more changes to the DBus library; in
particular a connectSessionWith and connectSystemWith to let me specify
my own clientThreadRunner.
So, it might be called sha1sum, or on some other OS, it might be called
sha1. It might be hidden away off of PATH on that OS. That's just expected
insanity; UNIX has been this way since 1980's. And these days, nobody even
gives the flying flip about standards that we briefly did in the 90's
after the first round of unix wars.
But it's the 2010's now, and we've certainly learned something.
So, let's make it so sometimes sha1 is a crazy program that wants to run as
root so it can lock memory while prompting for a passphrase, and outputting
binary garbage. Yes, that'd be wise. Let's package that in major Linux
distros, too, so users can stumble over it.
bup 0.25 does not accept that; and bup split reads from stdin by
default if no file is given. I'm not sure what version of bup changed this.
This only affected bup special remotes that were encrypted.
Monitors git-annex branch for changes, which are noticed by the Merger
thread whenever the branch ref is changed (either due to an incoming push,
or a local change), and refreshes cached config values for modified config
files.
Rate limited to run no more often than once per minute. This is important
because frequent git-annex branch changes happen when files are being
added, or transferred, etc.
A primary use case is that, when preferred content changes are made,
and get pushed to remotes, the remotes start honoring those settings.
Other use cases include propigating repository description and trust
changes to remotes, and learning when a remote has added a new special
remote, so the webapp can present the GUI to enable that special remote
locally.
Also added a uuid.log cache. All other config files already had caches.
in= was problimatic in two ways. First, it referred to a remote by name,
but preferred content expressions can be evaluated elsewhere, where that
remote doesn't exist, or a different remote has the same name. This name
lookup code could error out at runtime. Secondly, in= seemed pretty useless.
in=here did not cause content to be gotten, but it did let present content
be dropped.
present is more useful, although "not present" is unstable and should be
avoided.
When in a subdir, both the normal filepath, and the filepath relative to
the top of the git repo are needed for matching. The former for key lookup,
and the latter for include/exclude to match against. Previously, key lookup
didn't work in this situation.
The old code was just wrong in taking fromPath of GIT_DIR -- that made an
localUnknown location with the GIT_DIR in it, which only worked by
accident, and failed in submodules.
Now that this is handled correctly, git-annex can be used in git submodules.
Also, fixed infelicity where Git.CurrentRepo and Git.Config.updateLocation
were both dealing with core.worktree. Now updateLocation handles it for
Local as well as for LocalUnknown repos.
