I'm trying to slowly clean this up a bit, and moving functionality out
into the folder types and having those methods not reach into model is
part of it. That can mean takign some odd arguments in the meantime,
some of those should probably become interfaces or properties on folder
in the long term.
The functionality was anyway mostly implemented there and not isolated
in the folderScanner type. The attempt to refactor it out in the other
direction wouldn't work given that the event loop and stuff is on
`folder`.
This adds a couple of utilities for transporting databases in JSON and a
test to load a database and verify a couple of invalid bits. The test
itself is quite pointless at the moment, but it lays the groundwork for
testing the migration of this data in the next step (after the invalid
bit should be changed to local flags for local files).
When that happens we need to have a database in the old format already
there in order to be able to test the migration.
To newer names better reflecting their types and yet sorting together
with folder.go. Doing it now without asking because there are no open
PRs that will get killed by it, and to avoid bikeshedding the names.
The actual pull method (which is really the only thing that differs
between them) is now an interface member which gets overridden by the
subclass.
"Subclass?!" Well, this is dynamic dispatch with overriding, I guess.
Instead of walking and unmarshalling the entire db and sorting the resulting
file infos by sequence, add store device keys by sequence number in the
database. Thus only the required file infos need be unmarshalled and are already
sorted by index.
Bumping the limit to 2 * the max block size (16 MiB) is a slight
increase compared to previously. Nonetheless I think it's good to allow
us to queue one request and have one on the way in, or conversely have
one large block on the way in and be able to ask for smaller blocks from
others at the same time.
Two small behavior changes: don't "charge" the data to the global rate
limit until it's been accepted by the device specific limiter, and fix
the send/recv direction in the log print on per device rate limits.
clearAddresses write locks the struct and then calls notify. notify in turn tries to obtain a read lock on the same mutex. The result was a deadlock. This change unlocks the struct before calling notify.
Given that we've taken on the resposibility of maintaining this forked
package I've added it to the Syncthing organization. We still vendor it
like an external package, because it's convenient to keep it as a fork
of upstream to easier merge and file pull requests towards them.
When dropping delta index IDs due to upgrade, only drop our local one.
Previously, when dropping all of them, we would trigger a full send in
both directions on first connect after upgrade. Then the other side
would upgrade, doing the same thing. Net effect is full index data gets
sent twice in both directions.
With this change we just drop our local ID, meaning we will send our
full index on first connect after upgrade. When the other side upgrades,
they will do the same. This is a bit less cruel.
