Joey Hess bb4f31a0ee Clean up handling of git directory and git worktree. 
Baked into the code was an assumption that a repository's git directory
could be determined by adding ".git" to its work tree (or nothing for bare
repos). That fails when core.worktree, or GIT_DIR and GIT_WORK_TREE are
used to separate the two.

This was attacked at the type level, by storing the gitdir and worktree
separately, so Nothing for the worktree means a bare repo.

A complication arose because we don't learn where a repository is bare
until its configuration is read. So another Location type handles
repositories that have not had their config read yet. I am not entirely
happy with this being a Location type, rather than representing them
entirely separate from the Git type. The new code is not worse than the
old, but better types could enforce more safety.

Added support for core.worktree. Overriding it with -c isn't supported
because it's not really clear what to do if a git repo's config is read, is
not bare, and is then overridden to bare. What is the right git directory
in this case? I will worry about this if/when someone has a use case for
overriding core.worktree with -c. (See Git.Config.updateLocation)

Also removed and renamed some functions like gitDir and workTree that
misused git's terminology.

One minor regression is known: git annex add in a bare repository does not
print a nice error message, but runs git ls-files in a way that fails
earlier with a less nice error message. This is because before --work-tree
was always passed to git commands, even in a bare repo, while now it's not.

Raw Blame History

git-annex (3.20120512) UNRELEASED; urgency=low
* Pass -a to cp even when it supports --reflink=auto, to preserve
permissions.
* Clean up handling of git directory and git worktree.
-- Joey Hess <joeyh@debian.org> Tue, 15 May 2012 14:17:49 -0400
git-annex (3.20120511) unstable; urgency=low
* Rsync special remotes can be configured with shellescape=no
to avoid shell quoting that is normally done when using rsync over ssh.
This is known to be needed for certian rsync hosting providers
(specificially hidrive.strato.com) that use rsync over ssh but do not
pass it through the shell.
* dropunused: Allow specifying ranges to drop.
* addunused: New command, the opposite of dropunused, it relinks unused
content into the git repository.
* Fix use of several config settings: annex.ssh-options,
annex.rsync-options, annex.bup-split-options. (And adjust types to avoid
the bugs that broke several config settings.)
-- Joey Hess <joeyh@debian.org> Fri, 11 May 2012 12:29:30 -0400
git-annex (3.20120430) unstable; urgency=low
* Fix use of annex.diskreserve config setting.
* Directory special remotes now check annex.diskreserve.
* Support git's core.sharedRepository configuration.
* Add annex.http-headers and annex.http-headers-command config
settings, to allow custom headers to be sent with all HTTP requests.
(Requested by the Internet Archive)
* uninit: Clear annex.uuid from .git/config. Closes: #670639
* Added shared cipher mode to encryptable special remotes. This option
avoids gpg key distribution, at the expense of flexability, and with
the requirement that all clones of the git repository be equally trusted.
-- Joey Hess <joeyh@debian.org> Mon, 30 Apr 2012 13:16:10 -0400
git-annex (3.20120418) unstable; urgency=low
* bugfix: Adding a dotfile also caused all non-dotfiles to be added.
* bup: Properly handle key names with spaces or other things that are
not legal git refs.
* 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.
* Renamed diskfree.c to avoid OSX case insensativity bug.
* cabal now installs git-annex-shell as a symlink to git-annex.
* cabal file now autodetects whether S3 support is available.
-- Joey Hess <joeyh@debian.org> Wed, 18 Apr 2012 12:11:32 -0400
git-annex (3.20120406) unstable; urgency=low
* Disable diskfree on kfreebsd, as I have a build failure on kfreebsd-i386
that is quite likely caused by it.
-- Joey Hess <joeyh@debian.org> Sat, 07 Apr 2012 15:50:36 -0400
git-annex (3.20120405) unstable; urgency=low
* Rewrote free disk space checking code, moving the portability
handling into a small C library.
* status: Display amount of free disk space.
-- Joey Hess <joeyh@debian.org> Thu, 05 Apr 2012 16:19:10 -0400
git-annex (3.20120315) unstable; urgency=low
* fsck: Fix up any broken links and misplaced content caused by the
directory hash calculation bug fixed in the last release.
* sync: Sync to lower cost remotes first.
* status: Fixed to run in constant space.
* status: More accurate display of sizes of tmp and bad keys.
* unused: Now uses a bloom filter, and runs in constant space.
Use of a bloom filter does mean it will not notice a small
number of unused keys. For repos with up to half a million keys,
it will miss one key in 1000.
* Added annex.bloomcapacity and annex.bloomaccuracy, which can be
adjusted as desired to tune the bloom filter.
* status: Display amount of memory used by bloom filter, and
detect when it's too small for the number of keys in a repository.
* git-annex-shell: Runs hooks/annex-content after content is received
or dropped.
* Work around a bug in rsync (IMHO) introduced by openSUSE's SIP patch.
* git-annex now behaves as git-annex-shell if symlinked to and run by that
name. The Makefile sets this up, saving some 8 mb of installed size.
* git-union-merge is a demo program, so it is no longer built by default.
-- Joey Hess <joeyh@debian.org> Thu, 15 Mar 2012 11:05:28 -0400
git-annex (3.20120309) unstable; urgency=low
* Fix key directory hash calculation code to behave as it did before
version 3.20120227 when a key contains non-ascii characters (only
WORM backend is likely to have been affected).
-- Joey Hess <joeyh@debian.org> Fri, 09 Mar 2012 20:05:09 -0400
git-annex (3.20120230) unstable; urgency=low
* "here" can be used to refer to the current repository,
which can read better than the old "." (which still works too).
* Directory special remotes now support chunking files written to them,
avoiding writing files larger than a specified size.
* Add progress bar display to the directory special remote.
* Add configurable hooks that are run when git-annex starts and stops
using a remote: remote.name.annex-start-command and
remote.name.annex-stop-command
* Fix a bug in symlink calculation code, that triggered in rare
cases where an annexed file is in a subdirectory that nearly
matched to the .git/annex/object/xx/yy subdirectories.
-- Joey Hess <joeyh@debian.org> Mon, 05 Mar 2012 13:38:13 -0400
git-annex (3.20120229) unstable; urgency=low
* Fix test suite to not require a unicode locale.
* Fix cabal build failure. Thanks, Sergei Trofimovich
-- Joey Hess <joeyh@debian.org> Wed, 29 Feb 2012 02:31:31 -0400
git-annex (3.20120227) unstable; urgency=low
* Modifications to support ghc 7.4's handling of filenames.
This version can only be built with ghc 7.4 or newer. See the ghc7.0
branch for older ghcs.
* S3: Fix irrefutable pattern failure when accessing encrypted S3
credentials.
* Use the haskell IfElse library.
* Fix teardown of stale cached ssh connections.
* Fixed to use the strict state monad, to avoid leaking all kinds of memory
due to lazy state update thunks when adding/fixing many files.
* Fixed some memory leaks that occurred when committing journal files.
* Added a annex.queuesize setting, useful when adding hundreds of thousands
of files on a system with plenty of memory.
* whereis: Prints the urls of files that the web special remote knows about.
* addurl --fast: Verifies that the url can be downloaded (only getting
its head), and records the size in the key.
* When checking that an url has a key, verify that the Content-Length,
if available, matches the size of the key.
* addurl: Added a --file option, which can be used to specify what
file the url is added to. This can be used to override the default
filename that is used when adding an url, which is based on the url.
Or, when the file already exists, the url is recorded as another
location of the file.
* addurl: Normalize badly encoded urls.
* addurl: Add --pathdepth option.
* rekey: New plumbing level command, can be used to change the keys used
for files en masse.
* Store web special remote url info in a more efficient location.
(Urls stored with this version will not be visible to older versions.)
* Deal with NFS problem that caused a failure to remove a directory
when removing content from the annex.
* Make a single location log commit after a remote has received or
dropped files. Uses a new "git-annex-shell commit" command when available.
* To avoid commits of data to the git-annex branch after each command
is run, set annex.alwayscommit=false. Its data will then be committed
less frequently, when a merge or sync is done.
* configure: Check if ssh connection caching is supported by the installed
version of ssh and default annex.sshcaching accordingly.
* move --from, copy --from: Now 10 times faster when scanning to find
files in a remote on a local disk; rather than go through the location log
to see which files are present on the remote, it simply looks at the
disk contents directly.
-- Joey Hess <joeyh@debian.org> Mon, 27 Feb 2012 12:58:21 -0400
git-annex (3.20120123) unstable; urgency=low
* fsck --from: Fscking a remote is now supported. It's done by retrieving
the contents of the specified files from the remote, and checking them,
so can be an expensive operation. Still, if the remote is a special
remote, or a git repository that you cannot run fsck in locally, it's
nice to have the ability to fsck it.
* If you have any directory special remotes, now would be a good time to
fsck them, in case you were hit by the data loss bug fixed in the
previous release!
* fsck --from remote --fast: Avoids expensive file transfers, at the
expense of not checking file size and/or contents.
* Ssh connection caching is now enabled automatically by git-annex.
Only one ssh connection is made to each host per git-annex run, which
can speed some things up a lot, as well as avoiding repeated password
prompts. Concurrent git-annex processes also share ssh connections.
Cached ssh connections are shut down when git-annex exits.
* To disable the ssh caching (if for example you have your own broader
ssh caching configuration), set annex.sshcaching=false.
-- Joey Hess <joeyh@debian.org> Mon, 23 Jan 2012 13:48:48 -0400
git-annex (3.20120116) unstable; urgency=medium
* Fix data loss bug in directory special remote, when moving a file
to the remote failed, and partially transferred content was left
behind in the directory, re-running the same move would think it
succeeded and delete the local copy.
-- Joey Hess <joeyh@debian.org> Mon, 16 Jan 2012 16:43:45 -0400
git-annex (3.20120115) unstable; urgency=low
* Add a sanity check for bad StatFS results. On architectures
where StatFS does not currently work (s390, mips, powerpc, sparc),
this disables the diskreserve checking code, and attempting to
configure an annex.diskreserve will result in an error.
* Fix QuickCheck dependency in cabal file.
* Minor optimisations.
-- Joey Hess <joeyh@debian.org> Sun, 15 Jan 2012 13:54:20 -0400
git-annex (3.20120113) unstable; urgency=low
* log: Add --gource mode, which generates output usable by gource.
* map: Fix display of remote repos
* Add annex-trustlevel configuration settings, which can be used to
override the trust level of a remote.
* git-annex, git-union-merge: Support GIT_DIR and GIT_WORK_TREE.
* Add libghc-testpack-dev to build depends on all arches.
-- Joey Hess <joeyh@debian.org> Fri, 13 Jan 2012 15:35:17 -0400
git-annex (3.20120106) unstable; urgency=low
* Support unescaped repository urls, like git does.
* log: New command that displays the location log for files,
showing each repository they were added to and removed from.
* Fix overbroad gpg --no-tty fix from last release.
-- Joey Hess <joeyh@debian.org> Sat, 07 Jan 2012 13:16:23 -0400
git-annex (3.20120105) unstable; urgency=low
* Added annex-web-options configuration settings, which can be
used to provide parameters to whichever of wget or curl git-annex uses
(depends on which is available, but most of their important options
suitable for use here are the same).
* Dotfiles, and files inside dotdirs are not added by "git annex add"
unless the dotfile or directory is explicitly listed. So "git annex add ."
will add all untracked files in the current directory except for those in
dotdirs.
* Added quickcheck to build dependencies, and fail if test suite cannot be
built.
* fsck: Do backend-specific check before checking numcopies is satisfied.
* Run gpg with --no-tty. Closes: #654721
-- Joey Hess <joeyh@debian.org> Thu, 05 Jan 2012 13:44:12 -0400
git-annex (3.20111231) unstable; urgency=low
* sync: Improved to work well without a central bare repository.
Thanks to Joachim Breitner.
* Rather than manually committing, pushing, pulling, merging, and git annex
merging, we encourage you to give "git annex sync" a try.
* sync --fast: Selects some of the remotes with the lowest annex.cost
and syncs those, in addition to any specified at the command line.
* Union merge now finds the least expensive way to represent the merge.
* reinject: Add a sanity check for using an annexed file as the source file.
* Properly handle multiline git config values.
* Fix the hook special remote, which bitrotted a while ago.
* map: --fast disables use of dot to display map
* Test suite improvements. Current top-level test coverage: 75%
* Improve deletion of files from rsync special remotes. Closes: #652849
* Add --include, which is the same as --not --exclude.
* Format strings can be specified using the new --format option, to control
what is output by git annex find.
* Support git annex find --json
* Fixed behavior when multiple insteadOf configs are provided for the
same url base.
* Can now be built with older git versions (before 1.7.7); the resulting
binary should only be used with old git.
* Updated to build with monad-control 0.3.
-- Joey Hess <joeyh@debian.org> Sat, 31 Dec 2011 14:55:29 -0400
git-annex (3.20111211) unstable; urgency=medium
* Fix bug in last version in getting contents from bare repositories.
* Ensure that git-annex branch changes are merged into git-annex's index,
which fixes a bug that could cause changes that were pushed to the
git-annex branch to get reverted. As a side effect, it's now safe
for users to check out and commit changes directly to the git-annex
branch.
* map: Fix a failure to detect a loop when both repositories are local
and refer to each other with relative paths.
* Prevent key names from containing newlines.
* add: If interrupted, add can leave files converted to symlinks but not
yet added to git. Running the add again will now clean up this situtation.
* Fix caching of decrypted ciphers, which failed when drop had to check
multiple different encrypted special remotes.
* unannex: Can be run on files that have been added to the annex, but not
yet committed.
* sync: New command that synchronises the local repository and default
remote, by running git commit, pull, and push for you.
* Version monad-control dependency in cabal file.
-- Joey Hess <joeyh@debian.org> Sun, 11 Dec 2011 21:24:39 -0400
git-annex (3.20111203) unstable; urgency=low
* The VFAT filesystem on recent versions of Linux, when mounted with
shortname=mixed, does not get along well with git-annex's mixed case
.git/annex/objects hash directories. To avoid this problem, new content
is now stored in all-lowercase hash directories. Except for non-bare
repositories which would be a pain to transition and cannot be put on FAT.
(Old mixed-case hash directories are still tried for backwards
compatibility.)
* Flush json output, avoiding a buffering problem that could result in
doubled output.
* Avoid needing haskell98 and other fixes for new ghc. Thanks, Mark Wright.
* Bugfix: dropunused did not drop keys with two spaces in their name.
* Support for storing .git/annex on a different device than the rest of the
git repository.
* --inbackend can be used to make git-annex only operate on files
whose content is stored using a specified key-value backend.
* dead: A command which says that a repository is gone for good
and you don't want git-annex to mention it again.
-- Joey Hess <joeyh@debian.org> Sat, 03 Dec 2011 21:01:45 -0400
git-annex (3.20111122) unstable; urgency=low
* merge: Improve commit messages to mention what was merged.
* Avoid doing auto-merging in commands that don't need fully current
information from the git-annex branch. In particular, git annex add
no longer needs to auto-merge.
* init: When run in an already initalized repository, and without
a description specified, don't delete the old description.
* Optimised union merging; now only runs git cat-file once, and runs
in constant space.
* status: Now displays trusted, untrusted, and semitrusted repositories
separately.
* status: Include all special remotes in the list of repositories.
* status: Fix --json mode.
* status: --fast is back
* Fix support for insteadOf url remapping. Closes: #644278
* When not run in a git repository, git-annex can still display a usage
message, and "git annex version" even works.
* migrate: Don't fall over a stale temp file.
* Avoid excessive escaping for rsync special remotes that are not accessed
over ssh.
* find: Support --print0

git-annex (3.20111111) unstable; urgency=low
* Handle a case where an annexed file is moved into a gitignored directory,
by having fix --force add its change.
* Avoid cyclic drop problems.
* Optimized copy --from and get --from to avoid checking the location log
for files that are already present.
* Automatically fix up badly formatted uuid.log entries produced by
3.20111105, whenever the uuid.log is changed (ie, by init or describe).
* map: Support remotes with /~/ and /~user/
-- Joey Hess <joeyh@debian.org> Fri, 11 Nov 2011 13:44:18 -0400
git-annex (3.20111107) unstable; urgency=low
* merge: Use fast-forward merges when possible.
Thanks Valentin Haenel for a test case showing how non-fast-forward
merges could result in an ongoing pull/merge/push cycle.
* Don't try to read config from repos with annex-ignore set.
* Bugfix: In the past two releases, git-annex init has written the uuid.log
in the wrong format, with the UUID and description flipped.
-- Joey Hess <joeyh@debian.org> Mon, 07 Nov 2011 12:47:44 -0400
git-annex (3.20111105) unstable; urgency=low
* The default backend used when adding files to the annex is changed
from WORM to SHA256.
To get old behavior, add a .gitattributes containing: * annex.backend=WORM
* Sped up some operations on remotes that are on the same host.
* copy --to: Fixed leak when copying many files to a remote on the same
host.
* uninit: Add guard against being run with the git-annex branch checked out.
* Fail if --from or --to is passed to commands that do not support them.
* drop --from is now supported to remove file content from a remote.
* status: Now always shows the current repository, even when it does not
appear in uuid.log.
* fsck: Now works in bare repositories. Checks location log information,
and file contents. Does not check that numcopies is satisfied, as
.gitattributes information about numcopies is not available in a bare
repository.
* unused, dropunused: Now work in bare repositories.
* Removed the setkey command, and added a reinject command with a more
useful interface.
* The fromkey command now takes the key as its first parameter. The --key
option is no longer used.
* Built without any filename containing .git being excluded. Closes: #647215
* Record uuid when auto-initializing a remote so it shows in status.
* Bugfix: Fixed git-annex init crash in a bare repository when there was
already an existing git-annex branch.
* Pass -t to rsync to preserve timestamps.
-- Joey Hess <joeyh@debian.org> Sat, 05 Nov 2011 15:47:52 -0400
git-annex (3.20111025) unstable; urgency=low
* A remote can have a annexUrl configured, that is used by git-annex
instead of its usual url. (Similar to pushUrl.)
* migrate: Copy url logs for keys when migrating.
* git-annex-shell: GIT_ANNEX_SHELL_READONLY and GIT_ANNEX_SHELL_LIMITED
environment variables can be set to limit what commands can be run.
This is used by gitolite's new git-annex support!
-- Joey Hess <joeyh@debian.org> Tue, 25 Oct 2011 13:03:08 -0700
git-annex (3.20111011) unstable; urgency=low
* This version of git-annex only works with git 1.7.7 and newer.
The breakage with old versions is subtle, and affects the
annex.numcopies settings in .gitattributes, so be sure to upgrade git
to 1.7.7. (Debian package now depends on that version.)
* Don't pass absolute paths to git show-attr, as it started following
symlinks when that's done in 1.7.7. Instead, use relative paths,
which show-attr only handles 100% correctly in 1.7.7. Closes: #645046
* Fix referring to remotes by uuid.
* New or changed repository descriptions in uuid.log now have a timestamp,
which is used to ensure the newest description is used when the uuid.log
has been merged.
* Note that older versions of git-annex will display the timestamp as part
of the repository description, which is ugly but otherwise harmless.
* Add timestamps to trust.log and remote.log too.
* git-annex-shell: Added the --uuid option.
* git-annex now asks git-annex-shell to verify that it's operating in
the expected repository.
* Note that this git-annex will not interoperate with remotes using
older versions of git-annex-shell.
* Now supports git's insteadOf configuration, to modify the url
used to access a remote. Note that pushInsteadOf is not used;
that and pushurl are reserved for actual git pushes. Closes: #644278
* status: List all known repositories.
* When displaying a list of repositories, show git remote names
in addition to their descriptions.
* Add locking to avoid races when changing the git-annex branch.
* Various speed improvements gained by using ByteStrings.
* Contain the zombie hordes.

git-annex (3.20110928) unstable; urgency=low
* --in can be used to make git-annex only operate on files
believed to be present in a given repository.
* Arbitrarily complex expressions can be built to limit the files git-annex
operates on, by combining the options --not --and --or -( and -)
Example: git annex get --exclude '*.mp3' --and --not -( --in usbdrive --or --in archive -)
* --copies=N can be used to make git-annex only operate on files with
the specified number of copies. (And --not --copies=N for the inverse.)
* find: Rather than only showing files whose contents are present,
when used with --exclude --copies or --in, displays all files that
match the specified conditions.
* Note that this is a behavior change for git-annex find! Old behavior
can be gotten by using: git-annex find --in .
* status: Massively sped up; remove --fast mode.
* unused: File contents used by branches and tags are no longer
considered unused, even when not used by the current branch. This is
the final piece of the puzzle needed for git-annex to to play nicely
with branches.

git-annex (3.20110915) unstable; urgency=low
* whereis: Show untrusted locations separately and do not include in

* Fix build without S3.
* addurl: Always use whole url as destination filename, rather than
only its file component.
* get, drop, copy: Added --auto option, which decides whether
to get/drop content as needed to work toward the configured numcopies.
* bugfix: drop and fsck did not honor --exclude
-- Joey Hess <joeyh@debian.org> Thu, 15 Sep 2011 22:25:46 -0400
git-annex (3.20110906) unstable; urgency=low
* Improve display of newlines around error and warning messages.

-- Joey Hess <joeyh@debian.org> Tue, 06 Sep 2011 13:45:16 -0400
git-annex (3.20110902) unstable; urgency=low
* Set EMAIL when running test suite so that git does not need to be
configured first. Closes: #638998
* The wget command will now be used in preference to curl, if available.
* init: Make description an optional parameter.
* unused, status: Sped up by avoiding unnecessary stats of annexed files.
* unused --remote: Reduced memory use to 1/4th what was used before.
* Add --json switch, to produce machine-consumable output.
-- Joey Hess <joeyh@debian.org> Fri, 02 Sep 2011 21:20:37 -0400
git-annex (3.20110819) unstable; urgency=low
* Now "git annex init" only has to be run once, when a git repository
is first being created. Clones will automatically notice that git-annex
is in use and automatically perform a basic initalization. It's
still recommended to run "git annex init" in any clones, to describe them.
* Added annex-cost-command configuration, which can be used to vary the
cost of a remote based on the output of a shell command.
* Fix broken upgrade from V1 repository. Closes: #638584
-- Joey Hess <joeyh@debian.org> Fri, 19 Aug 2011 20:34:09 -0400
git-annex (3.20110817) unstable; urgency=low

* uninit: Delete the git-annex branch and .git/annex/
* unannex: In --fast mode, file content is left in the annex, and a
hard link made to it.
* uninit: Use unannex in --fast mode, to support unannexing multiple

* Now the web can be used as a special remote.
This feature replaces the old URL backend.
* addurl: New command to download an url and store it in the annex.
* Sped back up fsck, copy --from, and other commands that often
have to read a lot of information from the git-annex branch. Such
commands are now faster than they were before introduction of the
git-annex branch.
* Always ensure git-annex branch exists.
* Modify location log parser to allow future expansion.
* --force will cause add, etc, to operate on ignored files.
* Avoid mangling encoding when storing the description of repository
and other content.
* cabal can now be used to build git-annex. This is substantially
slower than using make, does not build or install documentation,
does not run the test suite, and is not particularly recommended,
but could be useful to some.

* git-annex now stores its logs in a git-annex branch.
* merge: New subcommand. Auto-merges the new git-annex branch.
* Improved handling of bare git repos with annexes. Many more commands will
work in them.
* git-annex is now more robust; it will never leave state files
uncommitted when some other git process comes along and locks the index
at an inconvenient time.
* rsync is now used when copying files from repos on other filesystems.
cp is still used when copying file from repos on the same filesystem,
since --reflink=auto can make it significantly faster on filesystems
such as btrfs.
* Allow --trust etc to specify a repository by name, for temporarily
trusting repositories that are not configured remotes.
* unlock: Made atomic.
* git-union-merge: New git subcommand, that does a generic union merge
operation, and operates efficiently without touching the working tree.

* bup is now supported as a special type of remote.
* The data sent to special remotes (Amazon S3, bup, etc) can be encrypted
using GPG for privacy.
* Use lowercase hash directories for locationlog files, to avoid
some issues with git on OSX with the mixed-case directories.
No migration is needed; the old mixed case hash directories are still
read; new information is written to the new directories.
* Unused files on remotes, particulary special remotes, can now be
identified and dropped, by using "--from remote" with git annex unused
and git annex dropunused.
* Clear up short option confusion between --from and --force (-f is now
--from, and there is no short option for --force).
* Add build depend on perlmagick so docs are consistently built.
Closes: #621410
* Add doc-base file. Closes: #621408

as hS3 is not packaged.
* fsck: Ensure that files and directories in .git/annex/objects

* Generalized remotes handling, laying groundwork for remotes that are
not regular git remotes. (Think Amazon S3.)
* Provide a less expensive version of `git annex copy --to`, enabled
via --fast. This assumes that location tracking information is correct,
rather than contacting the remote for every file.
* Bugfix: Keys could be received into v1 annexes from v2 annexes, via
v1 git-annex-shell. This results in some oddly named keys in the v1
annex. Recognise and fix those keys when upgrading, instead of crashing.

* 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 0.2x 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.
* Add annex.diskreserve config setting, to control how much free space
to reserve for other purposes and avoid using (defaults to 1 mb).
* Add --fast flag, that can enable less expensive, but also less thorough
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.
* migrate: Support migrating v1 SHA keys to v2 SHA keys with
size information that can be used for free space checking.
* Fix space leak in fsck and drop commands.

* The first time git-annex is run in an old format repository, it
will automatically upgrade it to the new format, staging all
necessary changes to git. Also added a "git annex upgrade" command.
* Colons are now avoided in filenames, so bare clones of git repos
can be put on USB thumb drives formatted with vFAT or similar
filesystems.
* Added two levels of hashing to object directory and .git-annex logs,
to improve scalability with enormous numbers of annexed
objects. (With one hundred million annexed objects, each
directory would contain fewer than 1024 files.)
* The setkey, fromkey, and dropkey subcommands have changed how

* Add Suggests on graphviz. Closes: #618039
* When adding files to the annex, the symlinks pointing at the annexed

git-annex (0.22) unstable; urgency=low
* Git annexes can now be attached to bare git repositories.
(Both the local and remote host must have this version of git-annex
installed for it to work.)
* Support filenames that start with a dash; when such a file is passed
to a utility it will be escaped to avoid it being interpreted as an
option. (I went a little overboard and got the type checker involved
in this, so such files are rather comprehensively supported now.)
* New backends: SHA512 SHA384 SHA256 SHA224
(Supported on systems where corresponding shaNsum commands are available.)
* describe: New subcommand that can set or change the description of
a repository.
* Fix test suite to reap zombies.
(Zombies can be particularly annoying on OSX; thanks to Jimmy Tang
for his help eliminating the infestation... for now.)
* Make test suite not rely on a working cp -pr.
(The Unix wars are still ON!)
* Look for dir.git directories the same as git does.
* Support remote urls specified as relative paths.
* Support non-ssh remote paths that contain tilde expansions.
* fsck: Check for and repair location log damage.

files or directories. For example, "git annex get a b" will now always
get "a" before "b". Previously it could operate in either order.
* unannex: Commit staged changes at end, to avoid some confusing behavior
with the pre-commit hook, which would see some types of commits after
an unannex as checking in of an unlocked file.
* map: New subcommand that uses graphviz to display a nice map of
the git repository network.

* untrust: Now marks the current repository as untrusted.
* semitrust: Now restores the default trust level. (What untrust used to do.)
* fsck, drop: Take untrusted repositories into account.
* Bugfix: Files were copied from trusted remotes first even if their
annex.cost was higher than other remotes.
* Improved temp file handling. Transfers of content can now be resumed
from temp files later; the resume does not have to be the immediate
next git-annex run.
* unused: Include partially transferred content in the list.
* Bugfix: Running a second git-annex while a first has a transfer in

git-annex (0.16) unstable; urgency=low
* git-annex-shell: Avoid exposing any git repo config except for the
annex.uuid when doing configlist.
* bugfix: Running `move --to` with a remote whose UUID was not yet known
could result in git-annex not recording on the local side where the
file was moved to. This could not result in data loss, or even a
significant problem, since the remote *did* record that it had the file.
* Also, add a general guard to detect attempts to record information
about repositories with missing UUIDs.
* bugfix: Running `move --to` with a non-ssh remote failed.
* bugfix: Running `copy --to` with a non-ssh remote actually did a move.

* Introduce the git-annex-shell command. It's now possible to make
a user have it as a restricted login shell, similar to git-shell.
* Note that git-annex will always use git-annex-shell when accessing

* The SHA1 backend is now fully usable.
* Add annex.version, which will be used to automate upgrades
