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.
- SyncJournalDB functions now behind internalPinStates() to avoid
accidental usage, when nearly everyone should go through Vfs.
- Rename Vfs::getPinState() to Vfs::pinState()
Seeing "Currently available online only" for a currently hydrated file
was odd. It makes sense since current hydration status and pin state are
independent.
The new text will say something like "Currently available, but marked
online only" to better indicate that the file might be dehydrated later
since it wasn't pinned.
supportsSelectiveSync(): clearer than !supportsVirtualFiles() and allows
extra logic
isVfsOnOffSwitchPending(): Somewhat awkward way of dealing with the
phase between a user requesting vfs state to be switched and it
actually happening
This allows enabling and disabling vfs.
To distinguish this operation from setting the root pin state, the
availability setting is adjusted as well to be similar to the
menu that shows in the shell extensions.
This is to avoid issues on OSX, where the ._ prefix has special meaning.
Originally (before 2.3.2) ._ was necessary to guarantee exclusion. But
since then the .sync_ prefix is excluded as well.
This does not affect existing database files.
Previously there'd likely be a mess if a 2.6 winvfs folder was attempted
to be used with a 2.5 client. Now the older clients will ignore these
folders.
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
