This adds a context.Context parameter to NewFs and related calls.
This is necessary as part of reading config from the context -
backends need to be able to read the global config.
Before ths fix --cutoff-mode soft and cautious would emit a Fatal
error which stopped the sync immediately.
This fix introduces a new error which is checked in the sync error
processing which stops the sync gracefully.
Fixes#4576
Before this change backends which introduce overhead (eg crypt) were
failing to upload the first file.
This change increases the threshold to 2k to allow the first file to
go through even with some overhead but the next file to definitely
fail.
Before this change we checked the transfer was out of range only
before the Read call. This means that we returned all the data to the
reader before declaring an error. This means that some backends wrote
the file even though an error was returned.
This fix checks the transfer after the Read as well, and chops the
excess characters off the read data if we are over the limit so that
we don't ever deliver all the data.
This fixes the tests introduced as part of 6f1766dd9e and #2672
on backends other than local.
Introduce stats groups that will isolate accounting for logically
different transferring operations. That way multiple accounting
operations can be done in parallel without interfering with each other
stats.
Using groups is optional. There is dedicated global stats that will be
used by default if no group is specified. This is operating mode for CLI
usage which is just fire and forget operation.
For running rclone as rc http server each request will create it's own
group. Also there is an option to specify your own group.
We now have a backend (fichier) which doesn't support 0 length
files. Therefore all 0 length files in the tests have been replaced
with length 1.
In a future commit we will implement a test for 0 length files.
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions
Context propagation is needed for stopping transfers and passing other
request-scoped values.
Before this change, when using rclone copy or move with --backup-dir
and the source was a single file, rclone would fail to use the backup
directory.
This change looks up the backup directory in the Fs cache and uses it
as appropriate.
This affects any commands which call operations.MoveFile or
operations.CopyFile which includes rclone move/moveto/copy/copyto
where the source is a single file.
Fixes#3219
In c5ac96e9e7 we made --files-from only read the objects specified and
don't scan directories.
This caused problems with Google drive (very very slow) and B2
(excessive API consumption) so it was decided to make the old
behaviour (traversing the directories) the default with --files-from
and use the existing --no-traverse flag (which has exactly the right
semantics) to enable the new non scanning behaviour.

This brings it up to par with lsjson.
This commit also reworks the framework to use ListJSON internally
which removes duplicated code and makes testing easier.
Before this change TestPurge would remove a container and subsequent
tests would fail because the container was still being deleted so
couldn't be created.
This was fixed by introducing an fstest.NewRunIndividual() test runner
for TestPurge which causes the test to be run on a new container.
Before this change, Purge on the fallback path would try to delete
directories starting from the root rather than the dir passed in.
Rmdirs would also attempt to delete the root.
Before this change using --files-from would scan all the directories
that the files could possibly be in causing rclone to do more work
that was necessary.
After this change, rclone constructs an in memory tree using the
--fast-list mechanism but from all of the files in the --files-from
list and without scanning any directories.
Any objects that are not found in the --files-from list are ignored
silently.
This mechanism is used for sync/copy/move (march) and all of the
listing commands ls/lsf/md5sum/etc (walk).
