There in no "return" in
PropagateUploadFileCommon::slotStartUpload in if (prevModtime != _item-
>_modtime) {... }
There is possibility that
PropagateItemJob::done(status, errorString)
maybe called two times from PropagateUploadFileCommon::slotStartUpload
1. in if (prevModtime != _item->_modtime) {... }
2. in if (fileIsStillChanging(*_item)) {..}
if changes in files are frequent the second call is possible.
This two calls has effect in PropagatorCompositeJob::slotSubJobFinished
and job is removed two times in _runningJobs.remove(i);
(the second time with argumetnt -1 (because first call removed job).
This return was removed in commit
efc039863b - by accident I think.
Good simulation is to synchronize firefox profile with frequent page
refresh.

Some servers have virus scanners and the like that can delay the
response of the final chunked upload assembly significantly, often
breaking the current 5min (!) timeout. See owncloud/enterprise#2480
for details.
Previously it tried to abort even jobs that had already finished, which
was not going to work as they wouldn't emit finished() again.
Also, in some cases the abortCount would never go to zero and that case
wasn't well documented.
If the code was not complex enough syncing two tables
already started to give UNIQUE constrains errors on
simple sync operations, this also adds initial support
remote delete of an encrypted file
If the server has the 'uploadConflictFiles' capability conflict
files will be uploaded instead of ignored.
Uploaded conflict files have the following headers set during upload
OC-Conflict: 1
OC-ConflictBaseFileId: 172489174instanceid
OC-ConflictBaseMtime: 1235789213
OC-ConflictBaseEtag: myetag
when the data is available. Downloads accept the same headers in return
when downloading a conflict file.
In the absence of server support clients will identify conflict files
through the file name pattern and attempt to deduce the base fileid.
Base etag and mtime can't be deduced though.
The upload job for a new conflict file will be triggered directly from
the job that created the conflict file now. No second sync run is
necessary anymore.
This commit does not yet introduce a 'username' like identifier that
automatically gets added to conflict file filenames (to name the files
foo_conflict-Fred-1345.txt instead of just foo_conflict-1345.txt).
The upload is made in an event loop with more than one
upload at the same time, this confuses the hell out of the
folder locking mechanism.
We need to lock the folder and ask the other trials to try
again in a few seconds in the future to give time for the
uploader to actually upload the current file that's locking
the folder.
Add a new member for the UploadFileInfo in PropagateUploadCommon
to hold the full file path - as it can change if we use a temporary
file to upload.
Adapt propagateuploadv1 to use the new calls.
They can be conceptually equal - I can upload the file
on disk, and that's what I do right now. But if we want
to accept filters in the future, filters that change
the file on disk like shrinking an image, the current
information used is wrong and we need a way to separate those.
This patch introduces a new struct that holds the *actual*
file that will be uploaded, be it a temporary one or
the original file.
This is motivated by the fact that QMetaObject::noralizeSignature takes 7.35%
CPU of the LargeSyncBench. (Mostly from ABstractNetworkJob::setupConnections and
PropagateUploadFileV1::startNextChunk). It could be fixed by using normalized
signature in the connection statement, but i tought it was a good oportunity
to modernize the code.
This commit only contains calls that were automatically converted with clazy.
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.
We need Qt 5.9 for HTTP2 because, even if Qt 5.8 already has support
for it, there is some critical bug in the HTTP2 implementation which
make it unusable [ https://codereview.qt-project.org/186050 and
https://codereview.qt-project.org/186066 ]
When using HTTP2, we can use many more parallel network request, this
is especially good for small file handling
Lower the priority of the GET and PUT propagation jobs, so the quota
or selective sync ui PROPFIND will not be blocked by them
It now produces a summary error message indicating the problem.
Adjust blacklist database table to contain 'errorCategory'. This is
useful for two things:
- Reestablishing summary messages based on blacklisted errors. For
example if we don't retry a 507ed file, we still want to show the
message about space on the server
- Selectively wiping the blacklist: When we have ui for something like
"I deleted some files, please retry all files now!", we want to
delete all blacklist entries of a specific category only.
* 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.
