It could happen that readyRead was emitted for incoming data while the
download was not yet finished. Then the network job could finish with
no more data arriving - so readyRead wasn't emitted again.
To fix this, the finished signal also gets connected to the readyRead
slot.
Paths can contain the wildcards % and _ and that would lead to odd
behavior.
This patch also clarifies the behavior of avoidReadFromDbOnNextSync()
which previously dependend on whether "foo/bar" or "foo/bar/" was
passed as input.
Possibly affects #6322
Previously we required matching mtimes but that's actually
unnecessary when the question is about whether to skip the
download. We will still update the file's metadata.
Also, adjust behavior when the checksum is weak (Adler32):
in these cases we still depend on equal mtimes.
... even if the file is not changed.
We get an UPDATE_METADATA in that case, so make sure we let the
SyncFileStatusTracker know about it.
That means we need to filter out UPDATE_METADATA in the other listeners
of this signal.
Issue #6098
When users share the same tree several times (say A/ and A/B/ are both
shared) the remote tree can have several entries that have the same
file id. This needs to be respected in rename detection.
Also adds several tests and fixes for issues noticed during testing.
See #6096
We mostly trust the file watchers meaning that we don't re-scan the
local tree if we have done that recently and no file watcher events
have arrived. If the file watchers invalidate a subtree, we rescan
only that subtree.
Since we're not entirely sure the file watchers are reliable, we still
do full local discoveries regularly (1h by default). There is a config
file setting as well as an environment variable to control the interval.
Comparison of file sizes for potential conflicts was added in
0eb9401c62, but did not extend to checking
the file size in case of potential local moves.
This commit adds this check and adds tests for various move+change
scenarios.
This gets rid of the csync_statedb sqlite layer and use
the same code and same connection as the rest of the SyncEngine.
Missing functions are added to SyncJournalDb and change a few minor
things (like changing SyncJournalFileRecord::_modtime to be an int64
instead of a QDateTime, like it was in csync).
The current implementation would return the same value whether the query failed
or if no row would be found. This is something that is currently checked by csync
and needs to be provided if we want to use SyncJournalDB there.
Adjusted all call sites to also check the return value even though they
could still just rely on rec.isValid(), but makes it more explicit as to what
happens for database errors in those cases, if we ever want to gracefully handle
them.
This remove the remaining "other" fields of the sync log to save a
bit of memory.
other_etag and other_fileId don't give much information to the users
and other_instruction will always be INST_NONE anyway.
other_modtime and other_size are kept since they are sometimes used.
They were renamed to have a bit more meaningful name.
SyncEngine::checkPermissions will now fetch its information from the
csync trees since they are now preserved until right after this point.
Fixes#3213
There was a rounding issue in the mtimes which sometimes resulted in an
off-by-one error. Caused by storing a full QDateTime in the FileInfo but
the mtime saved to the disk being truncated to seconds.
* For conflicts where mtime and size are identical:
a) If there's no remote checksum, skip (unchanged)
b) If there's a remote checksum that's a useful hash, create a
PropagateDownload job and compute the local hash. If the hashes
are identical, don't download the file and just update metadata.
* Avoid exposing the existence of checksumTypeId beyond the database
layer. This makes handling checksums easier in general because they
can usually be treated as a single blob.
This change was prompted by the difficulty of producing file_stat_t
entries uniformly from PROPFINDs and the database.
Issue #5783
When the directry that should be removed by selective sync contains changes,
we ignore the whole sub tree instead of only ignoreing new files.
We cannot ignore the whole directory, we need to ignore only the directory
that do not have files to remove
When a new folder becomes selective-sync excluded, we already mark it
and all its parent folders with _invalid_ etags to force rediscovery.
That's not enough however. Later calls to csync_statedb_get_below_path
could still pull data about the excluded files into the remote tree.
That lead to incorrect behavior, such as uploads happening for folders
that had been explicitly excluded from sync.
To fix the problem, statedb_get_below_path is adjusted to not read the
data about excluded folders from the database.
Currently we can't wipe this data from the database outright because we
need it to determine whether the files in the excluded folder can be
wiped away or not.
See owncloud/enterprise#1965
It could be possible that _firstJob is marked as finished if
aborted before its parent PropagateDirectory was marked as finished,
allowing a posted scheduleNextJob call to schedule the child job
in-between.
It could be possible that _firstJob is marked as finished if
aborted before its parent PropagateDirectory was marked as finished,
allowing a posted scheduleNextJob call to schedule the child job
in-between.
This was to catch duplicate emissions for PropagateDirectory but we
don't emit this signal anymore from there.
This fixes a warning about PropagatorJob not being a registered metatype.
This reverts commit fe42c1a818.
Issue #5224
Two problems:
- In the discovery phase, we need to check the selective sync entries of
the source path in case of renames.
- When the rename is done, we need to actually update the black list in the
database.
Two bugs:
- The change filed are not considered as move, they are re-downloaded
but the old file was not removed from the database. The change in
owncloudpropagator.cpp takes care of removing the old entries.
- Next sync would then remove the file in the server in the old folder
This was not a problem until we start reusing the sync engine, and
that the _renamedFolders map is not cleared. We were before deleting
a non-existing file. But now we delete the actual file.
Also improve the tests to be able to do move on the server.
This include support for file id.
Issue #5192
To be able to test the SyncEngine efficiently, a set of server
mocking classes have been implemented on top of QNetworkAccessManager.
The local disk side hasn't been mocked since this would require adding
a large abstraction layer in csync. The SyncEngine is instead pointed
to a different temporary dir in each test and we test by interacting
with files in this directory instead.
The FakeFolder object wraps the SyncEngine with those abstractions
and allow controlling the local files, and the fake remote state
through the FileModifier interface, using a FileInfo tree structure
for the remote-side implementation as well as feeding and comparing
the states on both side in tests.
Tests run fast and require no setup to be run, but each server feature
that we want to test on the client side needs to be implemented in
this fake objects library. For example, the OC-FileId header isn't
set as of this commit, and we can't test the file move logic properly
without implementing it first.
The TestSyncFileStatusTracker tests already contain a few QEXPECT_FAIL
for what I esteem being issues that need to be fixed in order to catch
up on our test coverage without making this patch too huge.
