Previously the source was deleted (or attempted to be deleted), even if
the new location was not acceptable for upload. This could make data
unavilable on the server.
For #7410
Previously the pin states of deleted files stayed in the 'flags'
database and could be inadvertently reused when a new file with the same
name appeared. Now they are deleted.
To make this work right, the meaning of the 'path' column in the 'flags'
table was changed: Previously it never had the .owncloud file suffix.
Now it's the same as in metadata.path.
This takes the safe parts from #7274 for inclusion in 2.6. The more
elaborate database schema changes (why use 'path' the join the two
tables in the first place?) shall go into master.
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 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.
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.
That change will be useful for the notifications. Previously the
dehydrated files were reported as "newly downloaded", now they're
reported as "updated".
- SyncJournalDB functions now behind internalPinStates() to avoid
accidental usage, when nearly everyone should go through Vfs.
- Rename Vfs::getPinState() to Vfs::pinState()
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.
This helps support 2.5 settings where there are virtual files in the
tree but new files aren't created virtual.
It's also a prelude for #6815
There's currently no way of
- upgrading vfs plugins (a silent suffix->winvfs upgrade is attempted
once only, when moving to master)
- disabling vfs capabilities outright
Inh most case we already have a record from before, so avoid doing a useless
lookup in the database.
In owncloudpropagator.cpp, directories do not have a checksum so no need
to call a function that preserves it
- adjust virtual file path handing
- helpers for vfs suffix adding/removal
- helpers for isDirectory/isVirtual on SyncJournalRecords
- be clear about what PathTuple _local/_server mean
So we can quickly query the items in a parent directory
This uses a custom slite3 function, which means that when downgrading the client,
or using another tool to add entries in the database, any insertion in the metadata
table will produce an error: "unknown function: parent_hash()"
(This will crash the client 2.5)
And test the Remove/Remove case.
This means we need to always query the database for all the entries.
This showed another small bug in the test in which sync item for virtual
files at the root could have a slash in front of them.
When resolving a conflict because the file was just updated on the server,
we write all the metadata on the database immediatly, so INSTRUCITON_NONE
is enough and UPDATE_METADATA is not needed
Move the finialization in its own function.
This allow to save a bit of code duplication.
Also change the order of the parameter in the constructor for consistency
