* fix some mixed space+tab indentationGravatar Joey Hess2014-10-09
| | | | | | | | | This fixes all instances of " \t" in the code base. Most common case seems to be after a "where" line; probably vim copied the two space layout of that line. Done as a background task while listening to episode 2 of the Type Theory podcast.

* direct: Fix ugly warning messages.Gravatar Joey Hess2014-08-12
| | | | | | | | | | | | | replaceFileOr was broken and ran the rollback action always. Luckily, for replaceFile, the rollback action was safe to run, since it just nuked a temp file that had already been moved into place. However, when `git annex direct` used replaeFileOr, its rollback printed a scary message: /home/joey/tmp/rrrr/.git/annex/misctmp/tmp32268: rename: does not exist (No such file or directory) There was actually no bad result though.
* unify exception handling into Utility.ExceptionGravatar Joey Hess2014-08-07
| | | | | | | | | | | | | | | | | | | | Removed old extensible-exceptions, only needed for very old ghc. Made webdav use Utility.Exception, to work after some changes in DAV's exception handling. Removed Annex.Exception. Mostly this was trivial, but note that tryAnnex is replaced with tryNonAsync and catchAnnex replaced with catchNonAsync. In theory that could be a behavior change, since the former caught all exceptions, and the latter don't catch async exceptions. However, in practice, nothing in the Annex monad uses async exceptions. Grepping for throwTo and killThread only find stuff in the assistant, which does not seem related. Command.Add.undo is changed to accept a SomeException, and things that use it for rollback now catch non-async exceptions, rather than only IOExceptions.
* direct: Fix handling of case where a work tree subdirectory cannot be ↵Gravatar Joey Hess2014-07-10
| | | | | | | | | written to due to permissions. Running `git annex direct` would cause loss of data, because the object was moved to a temp file, which it then tried to replace the work tree file with, and on failure, the temp file got deleted. Now it's instead moved back into the annex object location.
* Put non-object tmp files in .git/annex/misctmp, leaving .git/annex/tmp for ↵Gravatar Joey Hess2014-02-26
| | | | | | | | | | | | | | | | | | | | only partially transferred objects. This allows eg, putting .git/annex/tmp on a ram disk, if the disk IO of temp object files is too annoying (and if you don't want to keep partially transferred objects across reboots). .git/annex/misctmp must be on the same filesystem as the git work tree, since files are moved to there in a way that will not work cross-device, as well as symlinked into there. I first wanted to put the tmp objects in .git/annex/objects/tmp, but that would pose transition problems on upgrade when partially transferred objects existed. git annex info does not currently show the size of .git/annex/misctemp, since it should stay small. It would also be ok to make something clean it out, periodically.
* Fix a few bugs involving filenames that are at or near the filesystem's ↵Gravatar Joey Hess2013-07-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | maximum filename length limit. Started with a problem when running addurl on a really long url, because the whole url is munged into the filename. Ended up doing a fairly extensive review for places where filenames could get too large, although it's hard to say I'm not missed any.. Backend.Url had a 128 character limit, which is fine when the limit is 255, but not if it's a lot shorter on some systems. So check the pathconf() limit. Note that this could result in fromUrl creating different keys for the same url, if run on systems with different limits. I don't see this is likely to cause any problems. That can already happen when using addurl --fast, or if the content of an url changes. Both Command.AddUrl and Backend.Url assumed that urls don't contain a lot of multi-byte unicode, and would fail to truncate an url that did properly. A few places use a filename as the template to make a temp file. While that's nice in that the temp file name can be easily related back to the original filename, it could lead to `git annex add` failing to add a filename that was at or close to the maximum length. Note that in Command.Add.lockdown, the template is still derived from the filename, just with enough space left to turn it into a temp file. This is an important optimisation, because the assistant may lock down a bunch of files all at once, and using the same template for all of them would cause openTempFile to iterate through the same set of names, looking for an unused temp file. I'm not very happy with the relatedTemplate hack, but it avoids that slowdown. Backend.WORM does not limit the filename stored in the key. I have not tried to change that; so git annex add will fail on really long filenames when using the WORM backend. It seems better to preserve the invariant that a WORM key always contains the complete filename, since the filename is the only unique material in the key, other than mtime and size. Since nobody has complained about add failing (I think I saw it once?) on WORM, probably it's ok, or nobody but me uses it. There may be compatability problems if using git annex addurl --fast or the WORM backend on a system with the 255 limit and then trying to use that repo in a system with a smaller limit. I have not tried to deal with those. This commit was sponsored by Alexander Brem. Thanks!
* improve robustness of fromDirect and replaceFileGravatar Joey Hess2013-05-25
| | | | | | | | | Made fromDirect check that a file in the tree has good content (and is not a broken symlink either) before copying it to another file that has the same key. Made replaceFile clean up the temp file if the action that creates it, or the file replacement action fails.
* test suite passes in direct modeGravatar Joey Hess2013-05-17
This fixes a bug with git annex add in direct mode. If some files already existed in the tree pointing at the same key as a file that was just added, and their content was not present, add neglected to copy the content to those files. I also changed the behavior of moveAnnex slightly: When content is moved into the annex in direct mode, it does not overwrite any content already present in direct mode files. That content may be modified after all.
