# NAME
|
|
|
|
|
|
|
|
git-annex move - move content of files to/from another repository
|
|
|
|
|
|
|
|
# SYNOPSIS
|
|
|
|
|
move --to=here
* move --to=here moves from all reachable remotes to the local repository.
The output of move --from remote is changed slightly, when the remote and
local both have the content. It used to say:
move foo ok
Now:
move foo (from theremote...) ok
That was done so that, when move --to=here is used and the content is
locally present and also in several remotes, it's clear which remotes the
content gets dropped from.
Note that move --to=here will report an error if a non-reachable remote
contains the file, even if the local repository also contains the file. I
think that's reasonable; the user may be intending to move all other copies
of the file from remotes.
OTOH, if a copy of the file is believed to be present in some repository
that is not a configured remote, move --to=here does not report an error.
So a little bit inconsistent, but erroring in this case feels wrong.
copy --to=here came along for free, but it's basically the same behavior as
git-annex get, and probably with not as good messages in edge cases
(especially on failure), so I've not documented it.

|
|
|
|
Move the content of files that are in remote1 to remote2. Does not change
|
finishing up move --from --to
Lock the local content for drop after getting it from src, to prevent another
process from using the local content as a copy and dropping it from src,
which would prevent dropping the local content after sending it to dest.
Support resuming an interrupted move that downloaded the content from
src, leaving the local content populated. In this case, the location log
has not been updated to say the content is present locally, so we can
assume that it's resuming and go ahead and drop the local content after
sending it to dest.
Note that if a `git-annex get` is being ran at the same time as a
`git-annex move --from --to`, it may get a file just before the move
processes it. So the location log has not been updated yet, and the move
thinks it's resuming. Resulting in local copy being dropped after it's
sent to the dest. This race is something we'll just have to live with,
it seems.
I also gave up on the idea of checking if the location log had been updated
by a `git-annex get` that is ran at the same time. That wouldn't work, because
the location log is precached in the seek stage, so reading it again after
sending the content to dest would not notice changes made to it, unless the cache
were invalidated, which would slow it down a lot. That idea anyway was subject
to races where it would not detect the concurrent `git-annex get`.
So concurrent `git-annex get` will have results that may be surprising.
To make that less surprising, updated the documentation of this feature to
be explicit that it downloads content to the local repository
temporarily.

This is implemented by first downloading the content from remote1 to the
|
|
|
|
local repository (if not already present), then sending it to remote2, and
|
|
|
|
then deleting the content from the local repository (if it was not present
|
|
|
|
to start with).

copy/move --from-anywhere --to remote
Implementation was simple because it's equivilant to
--from=foo --to remote for each other remote, followed by
--to remote when there's a local copy.
(Or, in the edge case of --from-anywhere --to=here,
it's the same as --to=here.)
Note that, when the local repo does not have a copy,
fromToPerform gets it from a remote, sends it to the destination,
and drops the local copy. Another call to that for a second remote
will notice that the dest now has a copy, and simply drop from the
second remote, avoiding a second transfer.
Also note that, when numcopies doesn't allow dropping it from
everywhere, it will drop it from the cheapest remotes first
(maybe not ideal) up to more expensive remotes, and finally from the local
repo. So the local repo will generally end up holding a copy. Maybe not
ideal in all cases either, but it seems no worse to do that than to end up
with a copy undropped from a remote.
And I'm not entirely happy with the output, eg:
copy bigfile (from r3...) ok
copy bigfile ok
That makes sense if you think of the second line as being
the same as what is output by `git-annex copy bigfile --to bar`,
but it's less clear in this context. Maybe add "(from here...)"?
Also the --json output doesn't have a machine-readable field for
the "from" uuid, and maybe it should?

* `--from-anywhere --to=remote`
|
|
|
|
|
|
|
|
Move to the remote files from the local repository and from all
|
|
|
|
reachable remotes.

Note that, even without this option, you can move the content of a file
|
|
|
|
from one repository to another when numcopies is not satisfied, as long
|
|
|
|
as the move does not result in there being fewer copies.

* `--jobs=N` `-JN`
|
|
|

|
|
|
|
Enables parallel transfers with up to the specified number of jobs
|
|
|
|
running at once. For example: `-J10`
|
|
|
|
|
2019-05-10 17:24:31 +00:00

|
|
Setting this to "cpus" will run one job per CPU core.

|
|
|
|
2023-01-24 17:45:01 +00:00
|
|
|
Note that when using --from with --to, twice this many jobs will
|
|
|
|
run at once, evenly split between the two remotes.

Rather than specifying a filename or path to move, this option can be
|
|
|
|
used to move all available versions of all files.

This is the default behavior when running git-annex in a bare repository.
|
|
|
|
|
--branch, stage 1
Added --branch option to copy, drop, fsck, get, metadata, mirror, move, and
whereis commands. This option makes git-annex operate on files that are
included in a specified branch (or other treeish).
The names of the files from the branch that are being operated on are not
displayed yet; only the keys. Displaying the filenames will need changes
to every affected command.
Also, note that --branch can be specified repeatedly. This is not really
documented, but seemed worth supporting, especially since we may later want
the ability to operate on all branches matching a refspec. However, when
operating on two branches that contain the same key, that key will be
operated on twice.

* `--batch`
|
|
|
|
|
|
|
|
Enables batch mode, in which lines containing names of files to move
|
|
|
|
are read from stdin.
|
|
|
|
|
|
|
|
As each specified file is processed, the usual progress output is
|
make --batch honor matching options
When --batch is used with matching options like --in, --metadata, etc, only
operate on the provided files when they match those options. Otherwise, a
blank line is output in the batch protocol.
Affected commands: find, add, whereis, drop, copy, move, get
In the case of find, the documentation for --batch already said it honored
the matching options. The docs for the rest didn't, but it makes sense to
have them honor them. While this is a behavior change, why specify the
matching options with --batch if you didn't want them to apply?
Note that the batch output for all of the affected commands could
already output a blank line in other cases, so batch users should
already be prepared to deal with it.
git-annex metadata didn't seem worth making support the matching options,
since all it does is output metadata or set metadata, the use cases for
using it in combination with the martching options seem small. Made it
refuse to run when they're combined, leaving open the possibility for later
support if a use case develops.

displayed. If a file's content does not need to be moved,
|
|
|
|
or it does not match specified matching options, or it
|
2017-08-15 16:39:10 +00:00
|
|
|
is not an annexed file, a blank line is output in response instead.
|
|
|
|
|
|
|
|
Since the usual output while moving a file is verbose and not
|
|
|
|
machine-parseable, you may want to use --json in combination with
|
|
|
|
--batch.

* `--batch-keys`
|
|
|
|
|
|
|
|
This is like `--batch` but the lines read from stdin are parsed as keys.
|
|
|
|
|
added -z
Added -z option to git-annex commands that use --batch, useful for
supporting filenames containing newlines.
It only controls input to --batch, the output will still be line delimited
unless --json or etc is used to get some other output. While git often
makes -z affect both input and output, I don't like trying them together,
and making it affect output would have been a significant complication,
and also git-annex output is generally not intended to be machine parsed,
unless using --json or a format option.
Commands that take pairs like "file key" still separate them with a space
in --batch mode. All such commands take care to support filenames with
spaces when parsing that, so there was no need to change it, and it would
have needed significant changes to the batch machinery to separate tose
with a null.
To make fromkey and registerurl support -z, I had to give them a --batch
option. The implicit batch mode they enter when not provided with input
parameters does not support -z as that would have complicated option
parsing. Seemed better to move these toward using the same --batch as
everything else, though the implicit batch mode can still be used.
