Incomplete; I need to finish parsing and saving. This will also be used
for editing transfer control expresssions.
Removed the group display from the status output, I didn't really
like that format, and vicfg can be used to see as well as edit rempository
group membership.
Used by the assistant, rather than copy, this is faster because it avoids
using git ls-files, avoids checking the location log redundantly, and
runs in oneshot mode, avoiding making a commit to the git-annex branch
for every file transferred.
The environment needs to override git-config. Changed when git config is
read, and avoid rereading it once it's been read.
chdir for both worktree settings.
So far this only handles auto-annexing new files that are created inside
the repository while it's running. To make this really useful,
it needs to at least:
- notice deleted files and stage the deletion
(tricky; there's a race with add..)
- notice renamed files, auto-fix the symlink, and stage the new file location
- periodically auto-commit staged changes
- honor .gitignore, not adding files it excludes
Also nice to have would be:
- Somehow sync remotes, possibly using a push sync like dvcs-autosync
does, so they are immediately updated.
- Somehow get content that is unavilable. This is problimatic with inotify,
since we only get an event once the user has tried (and failed) to read
from the file. Perhaps instead, automatically copy content that is added
out to remotes, with the goal of all repos eventually getting a copy,
if df allows.
- Drop files that have not been used lately, or meet some other criteria
(as long as there's a copy elsewhere).
- Perhaps automatically dropunused files that have been deleted,
although I cannot see a way to do that, since by the time the inotify
deletion event arrives, the file is deleted, and we cannot see what
its symlink pointed to! Alternatievely, perhaps automatically
do an expensive unused/dropunused cleanup process.
Some of this probably needs the currently stateless threads to maintain
a common state.
git-annex (but not git-annex-shell) supports the git help.autocorrect
configuration setting, doing fuzzy matching using the restricted
Damerau-Levenshtein edit distance, just as git does. This adds a build
dependency on the haskell edit-distance library.
Done by adding a oneshot mode, in which location log changes are written to
the journal, but not committed. Taking advantage of git-annex's existing
ability to recover in this situation.
This is used by git-annex-shell and other places where changes are made to
a remote's location log.
This needs to run git log on the location log files to get at all past
versions of the file, which tends to be a bit slow.
It would be possible to make a version optimised for showing the location
logs for every key. That would only need to run git log once, so would be
faster, but it would need to process an enormous amount of data, so
would not speed up the individual file case.
In the future it would be nice to support log --format. log --json also
doesn't work right yet.
Made --from and --to command-specific options.
Added generic storage for values of command-specific options,
which allows removing some of the special case fields in AnnexState.
(Also added generic storage for command-specific flags, although there are
not yet any.)
Note that this storage uses a Map, so repeatedly looking up the same value
is slightly more expensive than looking up an AnnexState field. But, the
value can be looked up once in the seek stage, transformed as necessary,
and passed in a closure to the start stage, and this avoids that overhead.
Still, I'm hesitant to use this for things like force or fast flags.
It's probably best to reserve it for flags that are only used by a few
commands, or options like --from and --to that it's important only be
allowed to be used with commands that implement them, to avoid user
confusion.
It would be nice if command-specific options were supported. The first
difficulty is that which command is being called is not known until after
getopt; but that could be worked around by finding the first non-dashed
parameter. Storing the settings without putting them in the annex monad is
the next difficulty; it could perhaps be handled by making the seek stage
pass applicable settings into the start stage (and from there on to perform
as needed). But that still leaves a problem, what data type to use to
represent the options between getopt and seek?
Many functions took the repo as their first parameter. Changing it
consistently to be the last parameter allows doing some useful things with
currying, that reduce boilerplate.
In particular, g <- gitRepo is almost never needed now, instead
use inRepo to run an IO action in the repo, and fromRepo to get
a value from the repo.
This also provides more opportunities to use monadic and applicative
combinators.
This new approach allows filtering out checks from the default set that are
not appropriate for a command, rather than having to list every check
that is appropriate. It also reduces some boilerplate.
Haskell does not define Eq for functions, so I had to go a long way around
with each check having a unique id. Meh.
