For example, this could happen if using SHA1 and a file with content
"foo" were added to that backend. Then a file with "content" foo were
migrated from the WORM backend.
Assume that, if a backend assigned the same key, the already annexed
content must be the same. So, the "old" content can be reused.
The space leak was somehow caused by this line:
absfiles <- mapM absPath files
I confess, I don't quite understand why this caused bad buffering,
but apparently the whole pipeline from git-ls-files backed up at that
point.
Happily, rewriting the code to only get the cwd once and use a pure
function to calculate absfiles clears it up, and should be a little more
efficient in syscalls too.
Add --fast flag, that can enable less expensive, but also less thurough versions of some commands.
* Add --fast flag, that can enable less expensive, but also less thurough
versions of some commands.
* fsck: In fast mode, avoid checking checksums.
* unused: In fast mode, just show all existing temp files as unused,
and avoid expensive scan for other unused content.
Free space checking is now done, for transfers of data for keys that have free space metadata.
(Notably, not for SHA* keys generated with git-annex 0.24 or earlier.)
The code is believed to work on Linux, FreeBSD, and OSX; check compile-time
messages to see if it is not enabled for your OS.
When adding files to the annex, the symlinks pointing at the annexed
content are made to have the same mtime as the original file. While git
does not preserve that information, this allows a tool like metastore to be
used with annexed files.
Haskell's IO layer crashes on characters > 255 when in a non-unicode (latin1)
locale. Until Haskell gets better behavior, put in an admittedly ugly
workaround for that: git-annex forces utf8 output mode no matter what
locale is selected. So if you use a non-utf8 locale, your filenames with
characters > 127 will not be displayed as you'd expect. But at least it
won't crash.
