* finish fast direct mode rename handling. wow, it's fastGravatar Joey Hess2013-03-11

* remove Eq instance for InodeCacheGravatar Joey Hess2013-03-11
| | | | | | | | | There are two types of equality here, and which one is right varies, so this forces me to consider and choose between them. Based on this, I learned that the commit in git anex sync was always doing a strong comparison, even when in a repository where the inodes had changed. Fixed that.

* Direct mode: Fix support for adding a modified file.Gravatar Joey Hess2013-02-20
| | | | | | | | | | | Adding a file that is already annexed, but has been modified, was broken in direct mode. This fix makes the new content be added. It does have the problem that re-running `git annex add` will checksum and re-add the content repeatedly, until it's committed. This happens because the key associated with the file does not change until the new one gets committed, so it keeps thinking the file has changed.

* add: Improved detection of files that are modified while being added.Gravatar Joey Hess2013-02-14
| | | | | | | | | | | | | In indirect mode, now checks the inode cache to detect changes to a file. Note that a file can still be changed if a process has it open for write, after landing in the annex. In direct mode, some checking of the inode cache was done before, but from a much later point, so fewer modifications could be detected. Now it's as good as indirect mode. On crippled filesystems, no lock down is done before starting to add a file, so checking the inode cache is the only protection we have.

* crippled filesystem support, probing and initial supportGravatar Joey Hess2013-02-14
| | | | | | | | | | | | git annex init probes for crippled filesystems, and sets direct mode, as well as `annex.crippledfilesystem`. Avoid manipulating permissions of files on crippled filesystems. That would likely cause an exception to be thrown. Very basic support in Command.Add for cripped filesystems; avoids the lock down entirely since doing it needs both permissions and hard links. Will make this better soon.
* can now build Android targeted binaryGravatar Joey Hess2013-02-10
| | | | | | | | | | | | | | | | Various things that don't work on Android are just ifdefed out. * the webapp (needs template haskell for arm) * --include and --exclude globbing (needs libpcre, which is not ported; probably I'll make it use the pure haskell glob library instead) * annex.diskreserve checking (missing sys/statvfs.h) * timestamp preservation support (yawn) * S3 * WebDAV * XMPP The resulting 17mb binary has been tested on Android, and it is able to, at least, print its usage message.

* convert notBareRepo to a CommandCheckGravatar Joey Hess2012-12-29
| | | | | | This avoids some small overhead by only running the check once per command; it also ensures that, even if the command doesn't find anything to run on, it still fails to run when in a bare repo.

| | | | | Currently, it deletes files when run in one, so until I get a chance to fix it, block foot shooting.

| | | | | | | | Kqueue needs to remember which files failed to be added due to being open, and retry them. This commit gets the data in place for such a retry thread. Broke KeySource out into its own file, and added Eq and Ord instances so it can be stored in a Set.

* extend Git.Queue to be able to queue more than simple git commandsGravatar Joey Hess2012-06-07
| | | | | | While I was in there, I noticed and fixed a bug in the queue size calculations. It was never encountered only because Queue.add was only ever run with 1 file in the list.
* close the git add raceGravatar Joey Hess2012-06-06
| | | | | | | | | | | | | | | | | There's a race adding a new file to the annex: The file is moved to the annex and replaced with a symlink, and then we git add the symlink. If someone comes along in the meantime and replaces the symlink with something else, such as a new large file, we add that instead. Which could be bad.. This race is fixed by avoiding using git add, instead the symlink is directly staged into the index. It would be nice to make `git annex add` use this same technique. I have not done so yet because it currently runs git update-index once per file, which would slow does `git annex add`. A future enhancement would be to extend the Git.Queue to include the ability to run update-index with a list of Streamers.

* add: Prevent (most) modifications from being made to a file while it is ↵Gravatar Joey Hess2012-06-05
| | | | | | | | | | | being added to the annex. Anything that tries to open the file for write, or delete the file, or replace it with something else, will not affect the add. Only if a process has the file open for write before add starts can it still change it while (or after) it's added to the annex. (fsck will catch this later of course)

* rework git check-attr interfaceGravatar Joey Hess2012-02-13
| | | | | | | | | | | | | | | Now gitattributes are looked up, efficiently, in only the places that really need them, using the same approach used for cat-file. The old CheckAttr code seemed very fragile, in the way it streamed files through git check-attr. I actually found that cad8824852aa0623dc41eac02a9e2bae47d88ec4 was still deadlocking with ghc 7.4, at the end of adding a lot of files. This should fix that problem, and avoid future ones. The best part is that this removes withAttrFilesInGit and withNumCopies, which were complicated Seek methods, as well as simplfying the types for several other Seek methods that had a Backend tupled in.
* add: If interrupted, add can leave files converted to symlinks but not yet ↵Gravatar Joey Hess2011-12-07

* add support for using hashDirLower in addition to hashDirMixedGravatar Joey Hess2011-11-28
| | | | | | | | | | Supporting multiple directory hash types will allow converting to a different one, without a flag day. gitAnnexLocation now checks which of the possible locations have a file. This means more statting of files. Several places currently use gitAnnexLocation and immediately check if the returned file exists; those need to be optimised.
* support .git/annex on a different disk than the rest of the repoGravatar Joey Hess2011-11-28
| | | | | | | | | | | | | | | | | | The only fully supported thing is to have the main repository on one disk, and .git/annex on another. Only commands that move data in/out of the annex will need to copy it across devices. There is only partial support for putting arbitrary subdirectories of .git/annex on different devices. For one thing, but this can require more copies to be done. For example, when .git/annex/tmp is on one device, and .git/annex/journal on another, every journal write involves a call to mv(1). Also, there are a few places that make hard links between various subdirectories of .git/annex with createLink, that are not handled. In the common case without cross-device, the new moveFile is actually faster than renameFile, avoiding an unncessary stat to check that a file (not a directory) is being moved. Of course if a cross-device move is needed, it is as slow as mv(1) of the data.
* reorder repo parameters lastGravatar Joey Hess2011-11-08
| | | | | | | | | | | | | 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.

* clean up check selection codeGravatar Joey Hess2011-10-29
| | | | | | | | | 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.
