The db-close operation is likely a leftover from when the SyncEngine
owned its own db connection and serves no purpose anymore.
Closing the db causes the removal of the temporary wal and shm files.
These files are recreated when the db is opened again, which happens
almost immediately.
This is a problem for winvfs because the delete-recreate step wipes the
exclusion state on these files just after the sync is done. That meant
that the db temporaries permanently had a "needs sync" icon marker shown
in the explorer.
Avoiding reopening the db also reduces the number of log messages per
sync.
Previously these result codes during remote discovery of the sync root
would not cause an error and the discovery would get stuck.
Also extends RemoteDiscovery tests to check for errors on the root item.
Previously if one set the instruction to ERROR while forgetting to set
an error status, it'd propagate as FileIgnored. Now the default is
NormalError for INSTRUCTION_ERROR and FileIgnored for
INSTRUCTION_IGNORE.
The idea is that the user's question is "is this folder's data available
offline?" and not "does this folder have AlwaysLocal pin state?".
The the answers to the two questions can differ: an always-local
folder can have subitems that are not always-local and are dehydrated.
The new availability enum intends to describe the answer to the user's
actual question and can be derived from pin states. If pin states aren't
stored in the database the way of calculating availability will depend
on the vfs plugin.
The pin state is a per-item attribute that has an effect on _type:
AlwaysLocal dehydrated files will be marked for hydration and OnlineOnly
hydrated files will be marked for dehydration.
Where exactly this effect materializes depends on how the pin states are
stored. If they're stored in the db (suffix) the dbEntry._type is
changed during the discovery.
If the pin state is stored in the filesystem, the localEntry._type must
be adjusted by the plugin's stat callback.
This patch makes pin states behave more consistently between plugins.
Previously with suffix-vfs pin states only had an effect on new remote
files. Now the effect of pinning or unpinning files or directories is as
documented and similar to other plugins.
1. The _firstJob is usually deleted by the time the PropagateDirectory
finishes. (deleteLater() is called early)
2. The PropagateDirectory::_item and PropagateRemoteMkdir::_item point
to the same SyncFileItem anyway. This code is a leftover from when
each job had its own instance.
Previously removing the vfs suffix of a file always triggered a
conflict. Now it may just cause a file download.
This was done because users expected symmetry in the rename actions and
renaming foo -> foo.owncloud already triggers the "make the file
virtual" action. Now foo.owncloud -> foo triggers the "download the
contents" action.
Users can rename a file *and* add/remove the vfs suffix at the same time
leading to very complex sync actions. This patch doesn't add support for
them, but adds tests and makes sure these cases do not cause unintened
behavior.
The rename will be propagated, but the users's hydrate/dehydrate request
will be ignored.
This was not required with 2.5 because a size of 0 was ignorted when comparing
size by the csync updater, to be compatible with very old version of the database.
But the we discovery will still think the file is changed if the database contains
a size of 0
It seems that sometimes the tray implementation isn't ready on system
startup. Retrying later seems to not help. Delaying the start of the
client is the workaround that people have reported as effective.
When owncloud is started during desktop startup the tray may not yet
be running when the client starts. This will make the client attempt
to create a tray icon again after 10 seconds if there's no tray
during initial startup.
This could fix a problem where the client incorrectly decides to delete
local data.
Previously any sqlite3_step() return value that wasn't SQLITE_ROW would
be interpreted as "there's no more data here". Thus an sqlite error at a
bad time could cause the remote discovery to fail to read an unchanged
subtree from the database. These files would then be deleted locally.
With this change sqlite errors from sqlite3_step are detected and
logged. For the particular case of SyncJournalDb::getFilesBelowPath()
the error will now be propagated and the sync run will fail instead of
performing spurious deletes.
Note that many other database functions still don't distinguish
not-found from error cases. Most of them won't have as severe effects on
affected sync runs though.
It still reads and writes the old format too, but all newly stored
client certs will be in the new form.
For #6776 because Windows limits credential data to 512 bytes in older
versions.
By default, plugins are only searched next to the binary or next to the
other Qt plugins. This optional build variable allows another path to be
configured.
The idea is that on linux the oC packaging probably wants the binary in
something like /opt/owncloud/bin and the plugins in
/opt/owncloud/lib/plugins.
Similarly, distribution packagers probably don't want the plugins next
to the binary or next to the other Qt plugins. This flag allows them to
configure another path that the executable will look in.
doExpand() is called when the selective sync editing mode is enabled in
the folder settings view. Previously it'd set the expansion to be
exactly the root items. Now, it just expands any root items that are
currently collapsed, leaving all other item expansion unchanged.
With the recent bugfix to avoid sending messages on dead connections
0bfe7ac250c54f5415c0a794c7b271428e83c3cf
the client now crashed if readyRead() was received after disconnected()
for the socket as the listener for that connection was already removed.
This code fixes it by still invoking the handler from readyRead() but
passing a SocketListener that won't attempt to send messages.
As far as I'm aware local discovery can be skipped on folders that are
selective-sync blacklisted, so a local discovery is required when an
entry is removed from the blacklist.
Also rename
avoidReadFromDbOnNextSync() -> schedulePathForRemoteDiscovery()
since the old name might also imply it's not read from db in the local
discovery - which is not the case. Use Folder::
schedulePathForLocalDiscovery() for that.
Creating a new virtual file and replacing a file with a virtual one now
have their own text in the protocol, not just "Downloaded".
To do this, the SyncFileItem type is kept as
ItemTypeVirtualFileDehydration for these actions. Added new code to
ensure the type isn't written to the database.
While looking at this, I've also added documentation on SyncFileItem's
_file, _renameTarget, _originalFile and destination() because some of
the semantics weren't clear.
That change will be useful for the notifications. Previously the
dehydrated files were reported as "newly downloaded", now they're
reported as "updated".
