For each layout mode, these tests start with a git-annex-remote-rclone
remote, migrate it to a git-annex-remote-rclone-builtin remote. They
verify that a file copied pre-migration is still present and that `git
annex testremote` passes.
Issue #7625
Now that e2e tests are running in parallel, undoing the chdir to the
temp dir was causing flaky failures on cleanup. We don't need it anyway
because the worrisome subcommands have their working directory
controlled by `runInRepo()`.
Issue #7625
I'm hopeful that running these in parallel will not impact CI runtime
very much, but that likely depends on the number of CPU cores and
whether the tmp filesystem is backed by memory vs a physical disk.
Issue #7625
TestEndToEndRepoLayoutCompat exercises git-annex-remote-rclone-builtin
and git-annex-remote-rclone on the same rclone remote to ensure they are
compatible. It repeats the same test for all known layout modes.
Issue #7625
This commit adds support for the same repo layouts supported by
git-annex-remote-rclone. This should enable git-annex users with remotes
of type "rclone" to switch to a "rclone-builtin" without needing to
retransfer content.
Issue #7625
The .lck file filename length needs to be less than 255 bytes (not symbols) on
linux, and it was still too long on this test, because of the
subdir=測試_Русский_{spc}_{spc}_ě_áñ
on remotes with long names, such as TestChunkerChunk3bNoRenameLocal:

Before this change, the decoder looked only for `io.EOF`, and if any other error
was returned, it could cause an infinite loop. This change fixes the issue by
breaking for any non-nil error.
This enables compatibility with versions of git-annex currently
available on GitHub's "ubuntu-latest" image, aka Ubuntu 22.04 Jammy.
Currently, Jammy is shipping git-annex 8.20210223-2ubuntu2.

Issue #7625
This commit implements milestone 2.1 for the gitannex subcommand:
https://github.com/rclone/rclone/issues/7625#issuecomment-1951403856
This rewrite makes a few improvements over the old shell script:
(1) It no longer uses the system's rclone.conf. Now, it writes the
rclone.conf file in an ephemeral directory.
(2) It no longer makes any assumptions about the contents of /tmp.
However, it now assumes that an rclone built from the HEAD commit is on
the PATH. It makes a best-effort attempt to verify this assumption, but
I'm not sure it's bulletproof.
I'm hoping that writing this in Go will enable more cross-platform
support in the future, but for now we're still restricted to Unixy
systems due to reliance on the HOME environment variable.
Issue #7625
Before this change, calling SetModTime on owncloud and nextcloud would
inadvertently erase the object's stored hashes. This change fixes the issue,
which was discovered by the bisync integration tests.
- fix parsing of connection string remotes (comma in name)
- skip remotes that can't upload empty files
- Mkdir the test case subdir before cache.Get-ing it
(only storj seems to need this... bug?)
Several fixes for the bisync integration tests:
- use unique initdir and datadir for each subtest so concurrent tests don't interfere with each other
- remove dots from dir names for bucket backends
- ignore messages specific to cache backend
- skip fix-case tests on backends that can't fix-case
- don't expect "{hashtype} differ" messages on backends with no hash types
- print timestamps in UTC local
More fixes will still be needed, but this should hopefully fix a good portion of them.
This change officially adds bisync to the nightly integration tests for all
backends.
This will be part of giving us the confidence to take bisync out of beta.
A number of fixes have been added to account for features which can differ on
different backends -- for example, hash types / modtime support, empty
directories, unicode normalization, and unimportant differences in log output.
We will likely find that more of these are needed once we start running these
with the full set of remotes.
Additionally, bisync's extremely sensitive tests revealed a few bugs in other
backends that weren't previously covered by other tests. Fixes for those issues
have been submitted on the following separate PRs (and bisync test failures will
be expected until they are merged):
- #7670 memory: fix deadlock in operations.Purge
- #7688 memory: fix incorrect list entries when rooted at subdirectory
- #7690 memory: fix dst mutating src after server-side copy
- #7692 dropbox: fix chunked uploads when size <= chunkSize
Relatedly, workarounds have been put in place for the following backend
limitations that are unsolvable for the time being:
- #3262 drive is sometimes aware of trashed files/folders when it shouldn't be
- #6199 dropbox can't handle emojis and certain other characters
- #4590 onedrive API has longstanding bug for conflictBehavior=replace in
server-side copy/move
This change adds the --direct-io flag to the mount. This means the
page cache is completely bypassed for reads and writes. No read-ahead
takes place. Shared mmap is disabled.
This is useful to accurately read files which may change length
frequently on the source.
This commit adds a new subcommand named "gitannex", aka
"git-annex-remote-rclone-builtin" when invoked via a symlink.
This accomplishes milestone 1 from issue #7625: "minimal support for the
external special remote protocol".
Issue #7625
Before this change, directory modtimes (and metadata) were always synced from
src to dst, even if already in sync (i.e. their modtimes already matched.) This
potentially required excessive API calls, made logs noisy, and was potentially
problematic for backends that create "versions" or otherwise log activity
updates when modtime/metadata is updated.
After this change, a new DirsEqual function is added to check whether dirs are
equal based on a number of factors such as ModifyWindow and sync flags in use.
If the dirs are equal, the modtime/metadata update is skipped.
For backends that require setDirModTimeAfter, the "after" sync is performed only
for dirs that could have been changed by the sync (i.e. dirs containing files
that were created/updated.)
Note that dir metadata (other than modtime) is not currently considered by
DirsEqual, consistent with how object metadata is synced (only when objects are
unequal for reasons other than metadata).
To sync dir modtimes and metadata unconditionally (the previous behavior), use
--ignore-times.
Before this change, the VFS layer did not properly handle unicode normalization,
which caused problems particularly for users of macOS. While attempts were made
to handle it with various `-o modules=iconv` combinations, this was an imperfect
solution, as no one combination allowed both NFC and NFD content to
simultaneously be both visible and editable via Finder.
After this change, the VFS supports `--no-unicode-normalization` (default `false`)
via the existing `--vfs-case-insensitive` logic, which is extended to apply to both
case insensitivity and unicode normalization form.
This change also adds an additional flag, `--vfs-block-norm-dupes`, to address a
probably rare but potentially possible scenario where a directory contains
multiple duplicate filenames after applying case and unicode normalization
settings. In such a scenario, this flag (disabled by default) hides the
duplicates. This comes with a performance tradeoff, as rclone will have to scan
the entire directory for duplicates when listing a directory. For this reason,
it is recommended to leave this disabled if not needed. However, macOS users may
wish to consider using it, as otherwise, if a remote directory contains both NFC
and NFD versions of the same filename, an odd situation will occur: both
versions of the file will be visible in the mount, and both will appear to be
editable, however, editing either version will actually result in only the NFD
version getting edited under the hood. `--vfs-block-norm-dupes` prevents this
confusion by detecting this scenario, hiding the duplicates, and logging an
error, similar to how this is handled in `rclone sync`.
Before this change, NOTICE log messages during bisync dry runs were unclear as
to the direction of the skipped operation (Path1 to 2 vs. 2 to 1.) This change
adjusts the cmd/bisync/log.go indent function to be more expressive about
direction.
Directory mod times are synced by default if the backend is capable
and directory metadata is synced if the --metadata flag is provided
and the backend is capable.
This updates the bisync golden tests also which were affected by
--dry-run setting of directory modtimes.
Fixes#6685
A consequence of this is that fs.Directory returned by the local
backend will now have a correct size in (rather than -1). Some tests
depended on this and have been fixed by this commit too.
Before this change, nfsmount ignored the --volname flag. After this change, the --
volname flag is respected, making it possible to set a custom volume name.
macOS users should note that Finder will show the correct volume name in most
places, but a notable exception is the sidebar, which will show "localhost".
This seems to be a system limitation (at least without `sudo`), but see the
discussion at https://github.com/rclone/rclone/issues/7503#issuecomment-1933997678
for some possible workarounds.
Before this change, if a user unmounted externally (for example, via the Finder
UI), rclone would not be aware of this and wait forever to exit -- effectively
causing a deadlock that would require Ctrl+C to terminate.
After this change, when the handler detects an external unmount, it calls a
function which allows rclone to cleanly shutdown the VFS and exit.
