This can happen if the upload of a file is finished, but we just got
disconnected right before recieving the reply containing the etag.
So nothing was save din the DB, and we are not sure if the server
recieved the file properly or not. Further local update of the file
will cause a conflict.
In order to fix this, store the checksum of the uploading file in
the uploadinfo table of the local db (even if there is no chunking
involved). And when we have a conflict, check that it is not because
of this situation by checking the entry in the uploadinfo table.
Issue #5106
In addition to using the right function when retrieving inodes this
*also* fixes a more general bug ownsql had with storing uint64 values
that didn't fit into an int64.
Improves full matches by more than an order of magnitude
and also improves speed of traversal matches by roughly 20%,
judging by the check_csync_exclude performance test.
Make ExcludedFiles something that is instantiated outside of
the CSYNC context and then given to it as a hook.
ExcludedFiles still lives in csync_exclude and the internal
workings haven't been touched.
For duplicate file ids the update phase and reconcile phase determined
the rename mappings independently. If they disagreed (due to different
order of processing), complicated misbehavior would result.
This patch fixes it by letting reconcile try to use the mapping that the
update phase has computed first.
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.
On Mac, this halves the time spent in csync_excluded_traversal
when using check_csync_excluded_performance. A similar performance
increase is seen on linux.
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.
The code that was creating the files in the directory was removed in
commit 6906b8d30c. The directory is empty
so the result is expected to be null. It was passing before because the
code was returning an entry for . and .., but since commit
35f80bd439 this is no longer the case
Create a specific type that parses the permissions so we can store
it in a short rather than in a QByteArray
Note: in RemotePermissions::toString, we make sure the string is not
empty by adding a space, this was already existing before commit
e8f7adc7ca where it was removed by mistake.
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
Only store the path since they represent the same thing, and do the
phash conversion during DB lookup like done in libsync.
We could get rid of everything since we also have an index on the path
column, but since it's the primary key this makes the migration non-trivial.
Now that they use the same structure, avoid _csync_detect_update
having to recreate another instance and transfer everything manually.
Any instance created during discovery should now be used all the way
up to SyncEngine::treewalkFile.
This also makes sure that the path and types are properly set in that
object instead of having to pass everything as separate parameters.
This gets rid of csync_ftw_flags_e which was now converted from,
and to csync_ftw_type_e, already in the csync_file_stat_t.
Issue #1817
Otherwise adding patterns that start with # are impossible to add, since
they get treated as comments. Also add this escaping for patterns added
in the ui.
Merge csync_create and csync_init into the constructor and
replace csync_destroy with the destructor.
Also use a QByteArray for csync_s::root_perms and flatten
csync_rename_s as a rename sub-struct of csync_s since it
can now handle C++ types.
The only difference with csync_s::current is that it's
assigned the value of csync_s::local::type and
csync_s::remote::type, which never change. So might as
well only use the "current" field with constants.
Also move csync_normalize_etag to common/utility since we
don't need the char* function anymore.
Remove the single space file_stat->remotePerm codepath since
this won't be used in csync anymore since
8de3bda0b1.
Issue #1817
This is the first commit trying to unify csync_file_stat_s,
csync_vio_file_stat_s and csync_tree_walk_file_s. Use QByteArray
and unique_ptr already since I'm not used to track memory allocations
and this will make the transition easier.
Issue #1817
Now that csync builds as C++, this will avoid having to implement
functionalities needed by csync mandatorily in csync itself.
This library is built as part of libocsync and symbols exported
through it.
This requires a relicense of Utility as LGPL. All classes moved into
this library from src/libsync will need to be relicensed as well.
This will allow us to unify data structures between csync and libsync.
Utility functions like csync_time and c_std are still compiled as C
since we won't need to be coupled with Qt in the short term.
The QNAM may continue to outlive both.
Rename Credentials::getQNAM() to createQNAM() while we're at it - it's
used to make a new QNAM that will subsequently be owned by the Account
object.
See d01065b9a1 for rationale.

* SocketAPI has COPL_LOCAL_LINK / EMAIL_LOCAL_LINK commands
* The nautilus and dolphing shell integrations show a submenu from which
one can share as well as access the private link.
* The SocketAPI provides a new GET_STRINGS command to access localized
strings.
* The private link can also be accessed from the user/group sharing
dialog.
* The numeric file id is extracted from the full id to create the
private link url.
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.
This is useful for monitoring what kind of network requests are
sent to the fake server. Such as "did this sync cause an upload?"
and "was there a propfind for this path?". It can also inject
custom replies.
The client is very picky about date strings it accepts. If dates are
formatted with a non-C locale (such as localized weekday names), it
fails to parse it and tests fail in subtle ways.
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
* For requests:
- reuse the original QNetworkRequest, so headers and attributes
are the same as in the original request
- determine the original http method from the reply and the request
attributes
- keep the original request body around such that it can be sent
again in case the request is redirected
* Simplify the interface that is used for creating new requests in
AbstractNetworkJob.
