handle keys with extensions consistently in all locales 
Fix some cases where handling of keys with extensions varied depending on
the locale.

A filename with a unicode extension would before generate a key with an
extension in a unicode locale, but not in LANG=C, because the extension
was not all alphanumeric. Also the the length of the extension could be
counted differently depending on the locale.

In a non-unicode locale, git-annex migrate would see that the extension
was not all alphanumeric and want to "upgrade" it. Now that doesn't happen.

As far as backwards compatability, this does mean that unicode
extensions are counted by the number of bytes, not number of characters.
So, if someone is using unicode extensions, they may find git-annex
stops using them when adding files, because their extensions are too
long. Keys already in their repo with the "too long" extensions will
still work though, so this only prevents adding the same content with
the same extension generating the same key. Documented this by
documenting that annex.maxextensionlength is a number of bytes.

Also, if a filename has an extension that is not valid utf-8 and the
locale is utf-8, the extension will be allowed now, and an old
git-annex, in the same locale would not, and would also want to
"upgrade" that.

# NAME
git-annex - manage files with git, without checking their contents in
# SYNOPSIS
git annex command [params ...]
# DESCRIPTION
git-annex allows managing files with git, without checking the file
contents into git. While that may seem paradoxical, it is useful when
dealing with files larger than git can currently easily handle, whether due
to limitations in memory, checksumming time, or disk space.
Even without file content tracking, being able to manage files with git,
move files around and delete files with versioned directory trees, and use
branches and distributed clones, are all very handy reasons to use git. And
annexed files can co-exist in the same git repository with regularly
versioned files, which is convenient for maintaining documents, Makefiles,
etc that are associated with annexed files but that benefit from full
revision control.
When a file is annexed, its content is moved into a key-value store, and
a symlink is made that points to the content. These symlinks are checked into
git and versioned like regular files. You can move them around, delete
them, and so on. Pushing to another git repository will make git-annex
there aware of the annexed file, and it can be used to retrieve its
content from the key-value store.
# EXAMPLES

# COMMONLY USED COMMANDS
Like many git commands, git-annex can be passed a path that
is either a file or a directory. In the latter case it acts on all relevant
files in the directory. When no path is specified, most git-annex commands
default to acting on all relevant files in the current directory (and
subdirectories).
* `help`
Display built-in help.
For help on a specific command, use `git annex help command`
* `add [path ...]`
Adds files in the path to the annex. If no path is specified, adds
files from the current directory and below.
See [[git-annex-add]](1) for details.
* `get [path ...]`
Makes the content of annexed files available in this repository.
See [[git-annex-get]](1) for details.
* `drop [path ...]`
Drops the content of annexed files from this repository.

Automatically sync folders between devices.
See [[git-annex-assistant]](1) for details.
* `webapp`
Opens a web app, that allows easy setup of a git-annex repository,
and control of the git-annex assistant. If the assistant is not
already running, it will be started.
See [[git-annex-webapp]](1) for details.

in any tag or branch, and prints a numbered list of the data.
See [[git-annex-unused]](1) for details.
* `dropunused [number|range ...]`
Drops the data corresponding to the numbers, as listed by the last
`git annex unused`
See [[git-annex-dropunused]](1) for details.

* `forget`
Causes the git-annex branch to be rewritten, throwing away historical
data about past locations of files.
See [[git-annex-forget]](1) for details.
* `repair`
This can repair many of the problems with git repositories that `git fsck`
detects, but does not itself fix. It's useful if a repository has become
badly damaged. One way this can happen is if a repository used by git-annex
is on a removable drive that gets unplugged at the wrong time.
See [[git-annex-repair]](1) for details.
* `p2p`
Configure peer-2-Peer links between repositories.
See [[git-annex-p2p]](1) for details.

files. This is similar to whereis but a more compact display.
See [[git-annex-list]](1) for details.
* `log [path ...]`
Displays the location log for the specified file or files,
showing each repository they were added to ("+") and removed from ("-").
See [[git-annex-log]](1) for details.
* `info [directory|file|remote|uuid ...]`
Displays statistics and other information for the specified item,
which can be a directory, or a file, or a remote, or the uuid of a
repository.
When no item is specified, displays statistics and information
for the repository as a whole.
See [[git-annex-info]](1) for details.
* `version`
Shows the version of git-annex, as well as repository version information.
See [[git-annex-version]](1) for details.
* `map`
Generate map of repositories.
See [[git-annex-map]](1) for details.
* `inprogress`
Access files while they're being downloaded.
See [[git-annex-inprogress]](1) for details.
# METADATA COMMANDS
* `metadata [path ...]`
The content of an annexed file can have any number of metadata fields
attached to it to describe it. Each metadata field can in turn
have any number of values.
This command can be used to set metadata, or show the currently set
metadata.
See [[git-annex-metadata]](1) for details.
* `view [tag ...] [field=value ...] [field=glob ...] [!tag ...] [field!=value ...]`
Uses metadata to build a view branch of the files in the current branch,
and checks out the view branch. Only files in the current branch whose
metadata matches all the specified field values and tags will be
shown in the view.
See [[git-annex-view]](1) for details.
* `vpop [N]`
Switches from the currently active view back to the previous view.
Or, from the first view back to original branch.
See [[git-annex-vpop]](1) for details.
* `vfilter [tag ...] [field=value ...] [!tag ...] [field!=value ...]`
Filters the current view to only the files that have the
specified field values and tags.
See [[git-annex-vfilter]](1) for details.
* `vadd [field=glob ...] [field=value ...] [tag ...]`
Changes the current view, adding an additional level of directories
to categorize the files.
See [[git-annex-vfilter]](1) for details.
* `vcycle`
When a view involves nested subdirectories, this cycles the order.
See [[git-annex-vcycle]](1) for details.
# UTILITY COMMANDS
* `migrate [path ...]`
Changes the specified annexed files to use a different key-value backend.
See [[git-annex-migrate]](1) for details.
* `reinject src dest`
Moves the src file into the annex as the content of the dest file.
This can be useful if you have obtained the content of a file from
elsewhere and want to put it in the local annex.
See [[git-annex-reinject]](1) for details.
* `unannex [path ...]`
Use this to undo an accidental `git annex add` command. It puts the
file back how it was before the add.
See [[git-annex-unannex]](1) for details.
* `uninit`
De-initialize git-annex and clean out repository.
See [[git-annex-uninit]](1) for details.
* `reinit uuid|description`
Initialize repository, reusing old UUID.
See [[git-annex-reinit]](1) for details.
# PLUMBING COMMANDS
* `pre-commit [path ...]`
This is meant to be called from git's pre-commit hook. `git annex init`
automatically creates a pre-commit hook using this.
See [[git-annex-pre-commit]](1) for details.
* `post-receive`
This is meant to be called from git's post-receive hook. `git annex init`
automatically creates a post-receive hook using this.
See [[git-annex-post-receive]](1) for details.
* `lookupkey [file ...]`
Looks up key used for file.
See [[git-annex-lookupkey]](1) for details.
* `calckey [file ...]`
Calculates the key that would be used to refer to a file.
See [[git-annex-calckey]](1) for details.
* `contentlocation [key ..]`
Looks up location of annexed content for a key.
See [[git-annex-contentlocation]](1) for details.
* `examinekey [key ...]`
Print information that can be determined purely by looking at the key.
See [[git-annex-examinekey]](1) for details.
* `matchexpression`
Checks if a preferred content expression matches provided data.
See [[git-annex-matchexpression]](1) for details.
* `fromkey [key file]`
Manually set up a file in the git repository to link to a specified key.
See [[git-annex-fromkey]](1) for details.
* `registerurl [key url]`
Registers an url for a key.
See [[git-annex-registerurl]](1) for details.
* `setkey key file`
Moves a file into the annex as the content of a key.
See [[git-annex-setkey]](1) for details.
* `dropkey [key ...]`
Drops annexed content for specified keys.
See [[git-annex-dropkey]](1) for details.
* `transferkey key [--from=remote|--to=remote]`
Transfers a key from or to a remote.
See [[git-annex-transferkey]](1) for details.
* `transferkeys`
Used internally by the assistant.
See [[git-annex-transferkey]](1) for details.
* `setpresentkey key uuid [1|0]`
This plumbing-level command changes git-annex's records about whether
the specified key's content is present in a remote with the specified uuid.
See [[git-annex-setpresentkey]](1) for details.
* `readpresentkey key uuid`
Read records of where key is present.
See [[git-annex-readpresentkey]](1) for details.
* `checkpresentkey key remote`

See [[git-annex-checkpresentkey]](1) for details.
* `rekey [file key ...]`
Change keys used for files.
See [[git-annex-rekey]](1) for details.
* `resolvemerge`
Resolves a conflicted merge, by adding both conflicting versions of the
file to the tree, using variants of their filename. This is done
automatically when using `git annex sync` or `git annex merge`.
See [[git-annex-resolvemerge]](1) for details.
* `diffdriver`
This can be used to make `git diff` use an external diff driver with
annexed files.
See [[git-annex-diffdriver]](1) for details.
* `smudge`
This command lets git-annex be used as a git filter driver, allowing
annexed files in the git repository to be unlocked at all times, instead
of being symlinks.
See [[git-annex-smudge]](1) for details.
* `findref [ref]`
Lists files in a git ref. (deprecated)
See [[git-annex-findref]](1) for details.
* `proxy -- git cmd [options]`
Bypass direct mode guard. (deprecated)

# TESTING COMMANDS
* `test`
This runs git-annex's built-in test suite.
See [[git-annex-test]](1) for details.
* `testremote remote`
This tests a remote by generating some random objects and sending them to
the remote, then redownloading them, removing them from the remote, etc.
It's safe to run in an existing repository (the repository contents are
not altered), although it may perform expensive data transfers.
See [[git-annex-testremote]](1) for details.
* `fuzztest`
Generates random changes to files in the current repository,
for use in testing the assistant.
See [[git-annex-fuzztest]](1) for details.
* `benchmark`
This runs git-annex's built-in benchmarks, if it was built with
benchmarking support.
See [[git-annex-benchmark]](1) for details.
# COMMON OPTIONS
These common options are accepted by all git-annex commands, and
may not be explicitly listed on their individual man pages.
(Many commands also accept the [[git-annex-matching-options]](1).)
* `--force`
Force unsafe actions, such as dropping a file's content when no other
source of it can be verified to still exist, or adding ignored files.
Use with care.
* `--fast`
Enable less expensive, but also less thorough versions of some commands.
What is avoided depends on the command.
* `--quiet`
Avoid the default verbose display of what is done; only show errors.
* `--verbose`
Enable verbose display.
* `--debug`
Show debug messages.
* `--no-debug`
Disable debug messages.
* `--numcopies=n`
Overrides the numcopies setting, forcing git-annex to ensure the
specified number of copies exist.
Note that setting numcopies to 0 is very unsafe.
* `--time-limit=time`
Limits how long a git-annex command runs. The time can be something
like "5h", or "30m" or even "45s" or "10d".
Note that git-annex may continue running a little past the specified
time limit, in order to finish processing a file.
Also, note that if the time limit prevents git-annex from doing all it
was asked to, it will exit with a special code, 101.
* `--trust=repository`
* `--semitrust=repository`
* `--untrust=repository`
Overrides trust settings for a repository. May be specified more than once.
The repository should be specified using the name of a configured remote,
or the UUID or description of a repository.
* `--trust-glacier`
Amazon Glacier inventories take hours to retrieve, and may not represent
the current state of a repository. So git-annex does not trust that
files that the inventory claims are in Glacier are really there.
This switch can be used to allow it to trust the inventory.
Be careful using this, especially if you or someone else might have recently
removed a file from Glacier. If you try to drop the only other copy of the
file, and this switch is enabled, you could lose data!
* `--backend=name`
Specifies which key-value backend to use. This can be used when
adding a file to the annex, or migrating a file. Once files
are in the annex, their backend is known and this option is not
necessary.
* `--user-agent=value`
Overrides the User-Agent to use when downloading files from the web.
* `--notify-finish`
Caused a desktop notification to be displayed after each successful
file download and upload.
(Only supported on some platforms, e.g. Linux with dbus. A no-op when
not supported.)
* `--notify-start`
Caused a desktop notification to be displayed when a file upload
or download has started, or when a file is dropped.
* `-c name=value`
Overrides git configuration settings. May be specified multiple times.
# CONFIGURATION
Like other git commands, git-annex is configured via `.git/config`.
* `annex.uuid`
A unique UUID for this repository (automatically set).
* `annex.backend`
Name of the default key-value backend to use when adding new files
to the repository.
This is overridden by annex annex.backend configuration in the
.gitattributes files, and by the --backend option.
(This used to be named `annex.backends`, and that will still be used
if set.)
* `annex.securehashesonly`
Set to true to indicate that the repository should only use
cryptographically secure hashes (SHA2, SHA3) and not insecure
hashes (MD5, SHA1) for content.
When this is set, the contents of files using cryptographically
insecure hashes will not be allowed to be added to the repository.
Also, git-annex fsck` will complain about any files present in
the repository that use insecure hashes.
To configure the behavior in new clones of the repository,
this can be set using [[git-annex-config]].
* `annex.maxextensionlength`
Maximum length, in bytes, of what is considered a filename extension when
adding a file to a backend that preserves filename extensions. The
default length is 4, which allows extensions like "jpeg". The dot before
the extension is not counted part of its length. At most two extensions
at the end of a filename will be preserved, e.g. .gz or .tar.gz .
* `annex.diskreserve`
Amount of disk space to reserve. Disk space is checked when transferring
content to avoid running out, and additional free space can be reserved
via this option, to make space for more important content (such as git
commit logs). Can be specified with any commonly used units, for example,
"0.5 gb", "500M", or "100 KiloBytes"
The default reserve is 1 megabyte.
* `annex.largefiles`
Used to configure which files are large enough to be added to the annex.
It is an expression that matches the large files, eg
"include=*.mp3 or largerthan(500kb)"
See [[git-annex-matching-expression]](1) for details on the syntax.
Overrides any annex.largefiles attributes in `.gitattributes` files.
To configure a default annex.largefiles for all clones of the repository,
this can be set in [[git-annex-config]](1).
This configures the behavior of both git-annex and git when adding
files to the repository. By default, `git-annex add` adds all files
to the annex (except dotfiles), and `git add` adds files to git
(unless they were added to the annex previously).
When annex.largefiles is configured, both
`git annex add` and `git add` will add matching large files to the
annex, and the other files to git.
Other git-annex commands also honor annex.largefiles, including
`git annex import`, `git annex addurl`, `git annex importfeed`
and the assistant.
* `annex.dotfiles`
Normally, dotfiles are assumed to be files like .gitignore,
whose content should always be part of the git repository, so
they will not be added to the annex. Setting annex.dotfiles to true
makes dotfiles be added to the annex the same as any other file.
To annex only some dotfiles, set this and configure annex.largefiles
to match the ones you want. For example, to match only dotfiles ending
in ".big"
git config annex.largefiles "(include=.*.big or include=*/.*.big) or (exclude=.* and exclude=*/.*)"
git config annex.dotfiles true
To configure a default annex.dotfiles for all clones of the repository,
this can be set in [[git-annex-config]](1).
* `annex.gitaddtoannex`
Setting this to false will prevent `git add` from adding
files to the annex, despite the annex.largefiles configuration.
* `annex.addsmallfiles`
Controls whether small files (not matching annex.largefiles)
should be checked into git by `git annex add`. Defaults to true;
set to false to instead make small files be skipped.
* `annex.addunlocked`
Commands like `git-annex add` default to adding files to the repository
in locked form. This can make them add the files in unlocked form,
the same as if [[git-annex-unlock]](1) were run on the files.
This can be set to "true" to add everything unlocked, or it can be a more
complicated expression that matches files by name, size, or content. See
[[git-annex-matching-expression]](1) for details.
To configure a default annex.addunlocked for all clones of the repository,
this can be set in [[git-annex-config]](1).
(Using `git add` always adds files in unlocked form and it is not
affected by this setting.)
When a repository has core.symlinks set to false, or has an adjusted
unlocked branch checked out, this setting is ignored, and files are
always added to the repository in unlocked form.
* `annex.numcopies`
This is a deprecated setting. You should instead use the
`git annex numcopies` command to configure how many copies of files
are kept across all repositories, or the annex.numcopies .gitattributes
setting.
This config setting is only looked at when `git annex numcopies` has
never been configured, and when there's no annex.numcopies setting in the
.gitattributes file.
Note that setting numcopies to 0 is very unsafe.
* `annex.genmetadata`
Set this to `true` to make git-annex automatically generate some metadata
when adding files to the repository.
In particular, it stores year, month, and day metadata, from the file's
modification date.
When importfeed is used, it stores additional metadata from the feed,
such as the author, title, etc.
* `annex.used-refspec`
This controls which refs `git-annex unused` considers to be used.
See REFSPEC FORMAT in [[git-annex-unused]](1) for details.
* `annex.jobs`
Configure the number of concurrent jobs to run. Default is 1.
Only git-annex commands that support the --jobs option will
use this.
Setting this to "cpus" will run one job per CPU core.
* `annex.queuesize`
git-annex builds a queue of git commands, in order to combine similar
commands for speed. By default the size of the queue is limited to
10240 commands; this can be used to change the size. If you have plenty
of memory and are working with very large numbers of files, increasing
the queue size can speed it up.
* `annex.bloomcapacity`
The `git annex unused` and `git annex sync --content` commands use
a bloom filter to determine what files are present in eg, the work tree.
The default bloom filter is sized to handle
up to 500000 files. If your repository is larger than that,
you should increase this value. Larger values will
make `git-annex unused` and `git annex sync --content` consume more memory;
run `git annex info` for memory usage numbers.
* `annex.bloomaccuracy`
Adjusts the accuracy of the bloom filter used by
`git annex unused` and `git annex sync --content`.
The default accuracy is 10000000 -- 1 unused file out of 10000000
will be missed by `git annex unused`. Increasing the accuracy will make
`git annex unused` consume more memory; run `git annex info`
for memory usage numbers.
* `annex.sshcaching`
By default, git-annex caches ssh connections using ssh's
ControlMaster and ControlPersist settings
(if built using a new enough ssh). To disable this, set to `false`.
* `annex.alwayscommit`
By default, git-annex automatically commits data to the git-annex branch
after each command is run. If you have a series
of commands that you want to make a single commit, you can
run the commands with `-c annex.alwayscommit=false`. You can later
commit the data by running `git annex merge` (or by automatic merges)
or `git annex sync`.
You should beware running `git gc` when using this configuration,
since it could garbage collect objects that are staged in git-annex's
index but not yet committed.
* `annex.commitmessage`
When git-annex updates the git-annex branch, it usually makes up
its own commit message ("update"), since users rarely look at or
care about changes to that branch. If you do care, you can
specify this setting by running commands with
`-c annex.commitmessage=whatever`
This works well in combination with annex.alwayscommit=false,
to gather up a set of changes and commit them with a message you specify.
* `annex.allowsign`
By default git-annex avoids gpg signing commits that it makes when
they're not the purpose of a command, but only a side effect.
That default avoids lots of gpg password prompts when
commit.gpgSign is set. A command like `git annex sync` or `git annex merge`
will gpg sign its commit, but a command like `git annex get`,
that updates the git-annex branch, will not. The assistant also avoids
signing commits.
Setting annex.allowsign to true lets all commits be signed, as
controlled by commit.gpgSign and other git configuration.
* `annex.merge-annex-branches`
By default, git-annex branches that have been pulled from remotes
are automatically merged into the local git-annex branch, so that
git-annex has the most up-to-date possible knowledge.
To avoid that merging, set this to "false". This can be useful
particularly when you don't have write permission to the repository.
* `annex.hardlink`
Set this to `true` to make file contents be hard linked between the
repository and its remotes when possible, instead of a more expensive copy.
Use with caution -- This can invalidate numcopies counting, since
with hard links, fewer copies of a file can exist. So, it is a good
idea to mark a repository using this setting as untrusted.
When a repository is set up using `git clone --shared`, git-annex init
will automatically set annex.hardlink and mark the repository as
untrusted.
* `annex.thin`
Set this to `true` to make unlocked files be a hard link to their content
in the annex, rather than a second copy. This can save considerable
disk space, but when a modification is made to a file, you will lose the
local (and possibly only) copy of the old version. So, enable with care.
After setting (or unsetting) this, you should run `git annex fix` to
fix up the annexed files in the work tree to be hard links (or copies).
Note that this has no effect when the filesystem does not support hard links.
And when multiple files in the work tree have the same content, only
one of them gets hard linked to the annex.
* `annex.resolvemerge`
Set to false to prevent merge conflicts in the checked out branch
being automatically resolved by the git-annex assitant,
git-annex sync, git-annex merge,
and the git-annex post-receive hook.
To configure the behavior in all clones of the repository,
this can be set in [[git-annex-config]](1).
* `annex.synccontent`
Set to true to make git-annex sync default to syncing annexed content.
To configure the behavior in all clones of the repository,
this can be set in [[git-annex-config]](1).
* `annex.synconlyannex`
Set to true to make git-annex sync default to only sincing the git-annex
branch and annexed content.
To configure the behavior in all clones of the repository,
this can be set in [[git-annex-config]](1).
* `annex.debug`
Set to true to enable debug logging by default.
* `annex.version`
The current version of the git-annex repository. This is
maintained by git-annex and should never be manually changed.
* `annex.autoupgraderepository`
When an old git-annex repository version has become deprecated,
git-annex will normally automatically upgrade the repository to
the new version.
If this is set to false, git-annex won't automatically upgrade the
repository. Instead it will exit with an error message. You can run
`git annex upgrade` yourself when you are ready to upgrade the
repository.
* `annex.crippledfilesystem`
Set to true if the repository is on a crippled filesystem, such as FAT,
which does not support symbolic links, or hard links, or unix permissions.
This is automatically probed by "git annex init".
* `annex.pidlock`
Normally, git-annex uses fine-grained lock files to allow multiple
processes to run concurrently without getting in each others' way.
That works great, unless you are using git-annex on a filesystem that
does not support POSIX fcntl locks. This is sometimes the case when
using NFS or Lustre filesystems.
To support such situations, you can set annex.pidlock to true, and it
will fall back to a single top-level pid file lock.
Although, often, you'd really be better off fixing your networked
filesystem configuration to support POSIX locks.. And, some networked
filesystems are so inconsistent that one node can't reliably tell when
the other node is holding a pid lock. Caveat emptor.
* `annex.pidlocktimeout`
When using pid lock files, it's possible for a stale lock file to get
left behind by previous run of git-annex that crashed or was interrupted.
This is mostly avoided, but can occur especially when using a network
file system.
git-annex will wait up to this many seconds for the pid lock
file to go away, and will then abort if it cannot continue. Default: 300
* `annex.cachecreds`
When "true" (the default), git-annex will cache credentials used to
access special remotes in files in .git/annex/creds/
that only you can read. To disable that caching, set to "false",
and credentials will only be read from the environment, or if
they have been embedded in encrypted form in the git repository, will
be extracted and decrypted each time git-annex needs to access the
remote.
* `annex.secure-erase-command`
This can be set to a command that should be run whenever git-annex
removes the content of a file from the repository.
In the command line, %file is replaced with the file that should be
erased.
For example, to use the wipe command, set it to `wipe -f %file`.
* `annex.tune.objecthash1`, `annex.tune.objecthashlower`, `annex.tune.branchhash1`
These can be passed to `git annex init` to tune the repository.
They cannot be safely changed in a running repository and should never be
set in global git configuration.
For details, see <https://git-annex.branchable.com/tuning/>.
# CONFIGURATION OF REMOTES
Remotes are configured using these settings in `.git/config`.
* `remote.<name>.annex-cost`
When determining which repository to
transfer annexed files from or to, ones with lower costs are preferred.
The default cost is 100 for local repositories, and 200 for remote
repositories.
* `remote.<name>.annex-cost-command`
If set, the command is run, and the number it outputs is used as the cost.
This allows varying the cost based on e.g., the current network.
* `remote.<name>.annex-start-command`
A command to run when git-annex begins to use the remote. This can
be used to, for example, mount the directory containing the remote.
The command may be run repeatedly when multiple git-annex processes
are running concurrently.
* `remote.<name>.annex-stop-command`
A command to run when git-annex is done using the remote.
The command will only be run once *all* running git-annex processes
are finished using the remote.
* `remote.<name>.annex-shell`
Specify an alternative git-annex-shell executable on the remote
instead of looking for "git-annex-shell" on the PATH.
This is useful if the git-annex-shell program is outside the PATH
or has a non-standard name.
* `remote.<name>.annex-ignore`
If set to `true`, prevents git-annex
from storing file contents on this remote by default.
(You can still request it be used by the `--from` and `--to` options.)
This is, for example, useful if the remote is located somewhere
without git-annex-shell. (For example, if it's on GitHub).
Or, it could be used if the network connection between two
repositories is too slow to be used normally.
This does not prevent git-annex sync (or the git-annex assistant) from
syncing the git repository to the remote.
* `remote.<name>.annex-ignore-command`
If set, the command is run, and if it exits nonzero, that's the same
as setting annex-ignore to true. This allows controlling behavior based
on e.g., the current network.
* `remote.<name>.annex-sync`
If set to `false`, prevents git-annex sync (and the git-annex assistant)
from syncing with this remote by default. However, `git annex sync <name>`
can still be used to sync with the remote.
* `remote.<name>.annex-sync-command`
If set, the command is run, and if it exits nonzero, that's the same
as setting annex-sync to false. This allows controlling behavior based
on e.g., the current network.
* `remote.<name>.annex-pull`
If set to `false`, prevents git-annex sync (and the git-annex assistant
etc) from ever pulling (or fetching) from the remote.
* `remote.<name>.annex-push`
If set to `false`, prevents git-annex sync (and the git-annex assistant
etc) from ever pushing to the remote.
* `remote.<name>.annex-readonly`
If set to `true`, prevents git-annex from making changes to a remote.
This both prevents git-annex sync from pushing changes, and prevents
storing or removing files from read-only remote.
* `remote.<name>.annex-verify`, `annex.verify`
By default, git-annex will verify the checksums of objects downloaded
from remotes. If you trust a remote and don't want the overhead
of these checksums, you can set this to `false`.
Note that even when this is set to `false`, git-annex does verification
in some edge cases, where it's likely the case than an
object was downloaded incorrectly, or when needed for security.
* `remote.<name>.annex-tracking-branch`
This is for use with special remotes that support exports and imports.
When set to eg, "master", this tells git-annex that you want the
special remote to track that branch.
When set to eg, "master:subdir", the special remote tracks only
the subdirectory of that branch.
`git-annex sync --content` will import changes from the remote and
merge them into the annex-tracking-branch. They also export changes
made to the branch to the remote.
* `remote.<name>.annex-export-tracking`
Deprecated name for `remote.<name>.annex-tracking-branch`. Will still be used
if it's configured and `remote.<name>.annex-tracking-branch` is not.
* `remote.<name>.annexUrl`
Can be used to specify a different url than the regular `remote.<name>.url`
for git-annex to use when talking with the remote. Similar to the `pushUrl`
used by git-push.
* `remote.<name>.annex-uuid`
git-annex caches UUIDs of remote repositories here.
* `remote.<name>.annex-config-uuid`
Used for some special remotes, points to a different special remote
configuration to use.
* `remote.<name>.annex-retry`, `annex.retry`
Configure retries of failed transfers on a per-remote and general
basis, respectively. The value is the number of retries that can be
made of the same transfer. (default 0)
* `remote.<name>.annex-retry-delay`, `annex.retry-delay`
Number of seconds to delay before the first retry of a transfer.
When making multiple retries of the same transfer, the delay
doubles after each retry. (default 1)
* `remote.<name>.annex-checkuuid`
This only affects remotes that have their url pointing to a directory on
the same system. git-annex normally checks the uuid of such
remotes each time it's run, which lets it transparently deal with
different drives being mounted to the location at different times.
Setting annex-checkuuid to false will prevent it from checking the uuid
at startup (although the uuid is still verified before making any
changes to the remote repository). This may be useful to set to prevent
unncessary spin-up or automounting of a drive.
* `remote.<name>.annex-trustlevel`
Configures a local trust level for the remote. This overrides the value
configured by the trust and untrust commands. The value can be any of
"trusted", "semitrusted" or "untrusted".
* `remote.<name>.annex-availability`
Can be used to tell git-annex whether a remote is LocallyAvailable
or GloballyAvailable. Normally, git-annex determines this automatically.
* `remote.<name>.annex-speculate-present`
Set to "true" to make git-annex speculate that this remote may contain the
content of any file, even though its normal location tracking does not
indicate that it does. This will cause git-annex to try to get all file
contents from the remote. Can be useful in setting up a caching remote.
* `remote.<name>.annex-bare`
Can be used to tell git-annex if a remote is a bare repository
or not. Normally, git-annex determines this automatically.
* `remote.<name>.annex-ssh-options`
Options to use when using ssh to talk to this remote.
* `remote.<name>.annex-rsync-options`
Options to use when using rsync
to or from this remote. For example, to force IPv6, and limit
the bandwidth to 100Kbyte/s, set it to `-6 --bwlimit 100`
Note that git-annex-shell has a whitelist of allowed rsync options,
and others will not be be passed to the remote rsync. So using some
options may break the communication between the local and remote rsyncs.
* `remote.<name>.annex-rsync-upload-options`
Options to use when using rsync to upload a file to a remote.
These options are passed after other applicable rsync options,
so can be used to override them. For example, to limit upload bandwidth
to 10Kbyte/s, set `--bwlimit 10`.
* `remote.<name>.annex-rsync-download-options`
Options to use when using rsync to download a file from a remote.
These options are passed after other applicable rsync options,
so can be used to override them.
* `remote.<name>.annex-rsync-transport`
The remote shell to use to connect to the rsync remote. Possible
values are `ssh` (the default) and `rsh`, together with their
arguments, for instance `ssh -p 2222 -c blowfish`; Note that the
remote hostname should not appear there, see rsync(1) for details.
When the transport used is `ssh`, connections are automatically cached
unless `annex.sshcaching` is unset.
* `remote.<name>.annex-bup-split-options`
Options to pass to bup split when storing content in this remote.
For example, to limit the bandwidth to 100Kbyte/s, set it to `--bwlimit 100k`
(There is no corresponding option for bup join.)
* `remote.<name>.annex-gnupg-options`
Options to pass to GnuPG when it's encrypting data. For instance, to
use the AES cipher with a 256 bits key and disable compression, set it
to `--cipher-algo AES256 --compress-algo none`. (These options take
precedence over the default GnuPG configuration, which is otherwise
used.)
* `remote.<name>.annex-gnupg-decrypt-options`
Options to pass to GnuPG when it's decrypting data. (These options take
precedence over the default GnuPG configuration, which is otherwise
used.)
* `annex.ssh-options`, `annex.rsync-options`,
`annex.rsync-upload-options`, `annex.rsync-download-options`,
`annex.bup-split-options`, `annex.gnupg-options`,
`annex.gnupg-decrypt-options`
Default options to use if a remote does not have more specific options
as described above.
* `remote.<name>.annex-rsyncurl`
Used by rsync special remotes, this configures
the location of the rsync repository to use. Normally this is automatically
set up by `git annex initremote`, but you can change it if needed.
* `remote.<name>.annex-buprepo`
Used by bup special remotes, this configures
the location of the bup repository to use. Normally this is automatically
set up by `git annex initremote`, but you can change it if needed.
* `remote.<name>.annex-ddarrepo`
Used by ddar special remotes, this configures
the location of the ddar repository to use. Normally this is automatically
set up by `git annex initremote`, but you can change it if needed.
* `remote.<name>.annex-directory`
Used by directory special remotes, this configures
the location of the directory where annexed files are stored for this
remote. Normally this is automatically set up by `git annex initremote`,
but you can change it if needed.
* `remote.<name>.annex-adb`
Used to identify remotes on Android devices accessed via adb.
Normally this is automatically set up by `git annex initremote`.
* `remote.<name>.annex-androiddirectory`
Used by adb special remotes, this is the directory on the Android
device where files are stored for this remote. Normally this is
automatically set up by `git annex initremote`, but you can change
it if needed.
* `remote.<name>.annex-androidserial`
Used by adb special remotes, this is the serial number of the Android
device used by the remote. Normally this is automatically set up by
`git annex initremote`, but you can change it if needed, eg when
upgrading to a new Android device.
* `remote.<name>.annex-s3`
Used to identify Amazon S3 special remotes.
Normally this is automatically set up by `git annex initremote`.
* `remote.<name>.annex-glacier`
Used to identify Amazon Glacier special remotes.
Normally this is automatically set up by `git annex initremote`.
* `remote.<name>.annex-webdav`
Used to identify webdav special remotes.
Normally this is automatically set up by `git annex initremote`.
* `remote.<name>.annex-tahoe`
Used to identify tahoe special remotes.
Points to the configuration directory for tahoe.
* `remote.<name>.annex-gcrypt`
Used to identify gcrypt special remotes.
Normally this is automatically set up by `git annex initremote`.
It is set to "true" if this is a gcrypt remote.
If the gcrypt remote is accessible over ssh and has git-annex-shell
available to manage it, it's set to "shell".
* `remote.<name>.annex-git-lfs`
Used to identify git-lfs special remotes.
Normally this is automatically set up by `git annex initremote`.
It is set to "true" if this is a git-lfs remote.
* `remote.<name>.annex-hooktype`, `remote.<name>.annex-externaltype`
Used by hook special remotes and external special remotes to record
the type of the remote.
* `annex.web-options`
Options to pass to curl when git-annex uses it to download urls
(rather than the default built-in url downloader).
For example, to force IPv4 only, set it to "-4".
Or to make curl use your ~/.netrc file, set it to "--netrc".
Setting this option makes git-annex use curl, but only
when annex.security.allowed-ip-addresses is configured in a
specific way. See its documentation.
* `annex.youtube-dl-options`
Options to pass to youtube-dl when using it to find the url to download
for a video.
Some options may break git-annex's integration with youtube-dl. For
example, the --output option could cause it to store files somewhere
git-annex won't find them. Avoid setting here or in the youtube-dl config
file any options that cause youtube-dl to download more than one file,
or to store the file anywhere other than the current working directory.
* `annex.aria-torrent-options`
Options to pass to aria2c when using it to download a torrent.
* `annex.http-headers`
HTTP headers to send when downloading from the web. Multiple lines of
this option can be set, one per header.
* `annex.http-headers-command`
If set, the command is run and each line of its output is used as a HTTP
header. This overrides annex.http-headers.
* `annex.security.allowed-url-schemes`
List of URL schemes that git-annex is allowed to download content from.
The default is "http https ftp".
Think very carefully before changing this; there are security
implications. For example, if it's changed to allow "file" URLs, then
anyone who can get a commit into your git-annex repository could
`git-annex addurl` a pointer to a private file located outside that
repository, possibly causing it to be copied into your repository
and transferred on to other remotes, exposing its content.
Some special remotes support their own domain-specific URL
schemes; those are not affected by this configuration setting.
* `annex.security.allowed-ip-addresses`
By default, git-annex only makes connections to public IP addresses;
it will refuse to use HTTP and other servers on localhost or on a
private network.
This setting can override that behavior, allowing access to particular
IP addresses. For example "127.0.0.1 ::1" allows access to localhost
(both IPV4 and IPV6). To allow access to all IP addresses, use "all"
Think very carefully before changing this; there are security
implications. Anyone who can get a commit into your git-annex repository
could `git annex addurl` an url on a private server, possibly
causing it to be downloaded into your repository and transferred to
other remotes, exposing its content.
Note that, since the interfaces of curl and youtube-dl do not allow
these IP address restrictions to be enforced, curl and youtube-dl will
never be used unless annex.security.allowed-ip-addresses=all.
* `annex.security.allowed-http-addresses`
Old name for annex.security.allowed-ip-addresses.
If set, this is treated the same as having
annex.security.allowed-ip-addresses set.
* `annex.security.allow-unverified-downloads`
For security reasons, git-annex refuses to download content from
most special remotes when it cannot check a hash to verify
that the correct content was downloaded. This particularly impacts
downloading the content of URL or WORM keys, which lack hashes.
The best way to avoid problems due to this is to migrate files
away from such keys, before their content reaches a special remote.
See [[git-annex-migrate]](1).
When the content is only available from a special remote, you can
use this configuration to force git-annex to download it.
But you do so at your own risk, and it's very important you read and
understand the information below first!
Downloading unverified content from encrypted special remotes is
prevented, because the special remote could send some other encrypted
content than what you expect, causing git-annex to decrypt data that you
never checked into git-annex, and risking exposing the decrypted
data to any non-encrypted remotes you send content to.
Downloading unverified content from (non-encrypted)
external special remotes is prevented, because they could follow
http redirects to web servers on localhost or on a private network,
or in some cases to a file:/// url.
If you decide to bypass this security check, the best thing to do is
to only set it temporarily while running the command that gets the file.
The value to set the config to is "ACKTHPPT".
For example:
git -c annex.security.allow-unverified-downloads=ACKTHPPT annex get myfile
It would be a good idea to check that it downloaded the file you expected,
too.
* `remote.<name>.annex-security-allow-unverified-downloads`
Per-remote configuration of annex.security.allow-unverified-downloads.
# CONFIGURATION OF ASSISTANT
* `annex.delayadd`
Makes the watch and assistant commands delay for the specified number of
seconds before adding a newly created file to the annex. Normally this
is not needed, because they already wait for all writers of the file
to close it.
* `annex.expireunused`
Controls what the assistant does about unused file contents
that are stored in the repository.
The default is `false`, which causes
all old and unused file contents to be retained, unless the assistant
is able to move them to some other repository (such as a backup repository).
Can be set to a time specification, like "7d" or "1m", and then
file contents that have been known to be unused for a week or a
month will be deleted.
* `annex.fscknudge`
When set to false, prevents the webapp from reminding you when using
repositories that lack consistency checks.
* `annex.autoupgrade`
When set to ask (the default), the webapp will check for new versions
and prompt if they should be upgraded to. When set to true, automatically
upgrades without prompting (on some supported platforms). When set to
false, disables any upgrade checking.
Note that upgrade checking is only done when git-annex is installed
from one of the prebuilt images from its website. This does not
bypass e.g., a Linux distribution's own upgrade handling code.
This setting also controls whether to restart the git-annex assistant
when the git-annex binary is detected to have changed. That is useful
no matter how you installed git-annex.
* `annex.autocommit`
Set to false to prevent the git-annex assistant and git-annex sync
from automatically committing changes to files in the repository.
To configure the behavior in all clones of the repository,
this can be set in [[git-annex-config]](1).
* `annex.startupscan`
Set to false to prevent the git-annex assistant from scanning the
repository for new and changed files on startup. This will prevent it
from noticing changes that were made while it was not running, but can be
a useful performance tweak for a large repository.
* `annex.listen`
Configures which address the webapp listens on. The default is localhost.
Can be either an IP address, or a hostname that resolves to the desired
address.
# CONFIGURATION VIA .gitattributes
The key-value backend used when adding a new file to the annex can be
configured on a per-file-type basis via `.gitattributes` files. In the file,
the `annex.backend` attribute can be set to the name of the backend to
use. For example, this here's how to use the WORM backend by default,
but the SHA256E backend for ogg files:
* annex.backend=WORM
*.ogg annex.backend=SHA256E
There is a annex.largefiles attribute, which is used to configure which
files are large enough to be added to the annex. Since attributes cannot
contain spaces, it is difficult to use for more complex annex.largefiles
settings. Setting annex.largefiles in [[git-annex-config]](1) is an easier
way to configure it across all clones of the repository.
See [[git-annex-matching-expression]](1) for details on the syntax.
The numcopies setting can also be configured on a per-file-type basis via
the `annex.numcopies` attribute in `.gitattributes` files. This overrides
other numcopies settings.
For example, this makes two copies be needed for wav files and 3 copies
for flac files:
*.wav annex.numcopies=2
*.flac annex.numcopies=3
Note that setting numcopies to 0 is very unsafe.
These settings are honored by git-annex whenever it's operating on a
matching file. However, when using --all, --unused, or --key to specify
keys to operate on, git-annex is operating on keys and not files, so will
not honor the settings from .gitattributes. For this reason, the `git annex
numcopies` command is useful to configure a global default for numcopies.
Also note that when using views, only the toplevel .gitattributes file is
preserved in the view, so other settings in other files won't have any
effect.
# EXIT STATUS
git-annex, when called as a git subcommand, may return exit codes 0 or 1
for success or failures, or, more rarely, 127 or 128 for certain very
specific failures. git-annex itself should return 0 on success and 1 on
failure, unless the `--time-limit=time` option is hit, in which case it
returns with exit code 101.
# ENVIRONMENT
These environment variables are used by git-annex when set:
* `GIT_WORK_TREE`, `GIT_DIR`
Handled the same as they are by git, see git(1)
* `GIT_SSH`, `GIT_SSH_COMMAND`
Handled similarly to the same as described in git(1).
The one difference is that git-annex will sometimes pass an additional
"-n" parameter to these, as the first parameter, to prevent ssh from
reading from stdin. Since that can break existing uses of these
environment variables that don't expect the extra parameter, you will
need to set `GIT_ANNEX_USE_GIT_SSH=1` to make git-annex support
these.
Note that setting either of these environment variables prevents
git-annex from automatically enabling ssh connection caching
(see `annex.sshcaching`), so it will slow down some operations with
remotes over ssh. It's up to you to enable ssh connection caching
if you need it; see ssh's documentation.
Also, `annex.ssh-options` and `remote.<name>.annex-ssh-options`
won't have any effect when these envionment variables are set.
Usually it's better to configure any desired options through your
~/.ssh/config file, or by setting `annex.ssh-options`.
* `GIT_ANNEX_VECTOR_CLOCK`
Normally git-annex timestamps lines in the log files committed to the
git-annex branch. Setting this environment variable to a number
will make git-annex use that rather than the current number of seconds
since the UNIX epoch. Note that decimal seconds are supported.
This is only provided for advanced users who either have a better way to
tell which commit is current than the local clock, or who need to avoid
embedding timestamps for policy reasons. Misuse of this environment
variable can confuse git-annex's book-keeping, sometimes in ways that
`git annex fsck` is unable to repair.
Some special remotes use additional environment variables
for authentication etc. For example, `AWS_ACCESS_KEY_ID`
and `GIT_ANNEX_P2P_AUTHTOKEN`. See special remote documentation.
# FILES
These files are used by git-annex:
`.git/annex/objects/` in your git repository contains the annexed file
contents that are currently available. Annexed files in your git
repository symlink to that content.
`.git/annex/` in your git repository contains other run-time information
used by git-annex.
`~/.config/git-annex/autostart` is a list of git repositories
to start the git-annex assistant in.
`.git/hooks/pre-commit-annex` in your git repository will be run whenever
a commit is made to the HEAD branch, either by git commit, git-annex
sync, or the git-annex assistant.
`.git/hooks/post-update-annex` in your git repository will be run
whenever the git-annex branch is updated. You can make this hook run
`git update-server-info` when publishing a git-annex repository by http.
