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 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.
From issue #7015, the code is wrong because the path is the file system path and
not the path on the DB.
But since this is a conflict, this means the reconcile will still want to download
the file from the server next sync, so we need not to worry about this case
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".
That just complicated things. It's ok if Vfs is not a fully abstract
interface class.
The pinstate-in-db methods are instead provided directly on Vfs and
VfsSuffix and VfsOff use them to implement pin states.
The start() method is simply non-virtual and calls into startImpl() for
the plugin-specific startup code.
The block of code that propagated attributes etc from the previously
existing file was placed *after* the block that renamed the previously
existing file to a conflict name. That meant the propagation didn't work
in the conflict case.
- SyncJournalDB functions now behind internalPinStates() to avoid
accidental usage, when nearly everyone should go through Vfs.
- Rename Vfs::getPinState() to Vfs::pinState()
Any folder with a (potentially deeply) contained error will have
StatusWarning. StatusExcluded marks exclusions. The difference is useful
to know for VFS.
This will be used in conjunction with vfs plugins that detect whether a
file has a pending hydration/dehydration through independent means and
communicate that to the discovery through local file type.
Since 'placeholder' just means that it's an item of the special type
that the vfs plugin can deal with - no matter whether hydrated or
dehydrated - all done items should become placeholders. Even
directories.
Now every file that passes through updateMetadata() will be converted to
a placeholder if necessary.
On Linux and Windows the file watcher can't distinguish between changes
that were caused by the process itself, like during a sync operation,
and external changes. To work around that the client keeps a list of
files it has touched and blocks notifications on these files for a bit.
The duration of this block was originally and arbitrarily set at 15
seconds. During manual tests I regularly thought there was a bug when
syncs didn't trigger, when the only problem was that my changes happened
too close to a previous sync operation.
This change reduces the duration to three seconds. I imagine that this
is still enough.
Also use std::chrono while at it.
