Returns 'ok' if the server is the leader or a follower with
a 'caught up' log.
This is mainly for HTTP connections that are using an
orchestration environment like kubernetes, but will work as a
general RESP command.
For HTTP a '200 OK' for 'caught up' and
'500 Internal Server Error' otherwise.
See #608
Prior to this commit roaming geofences only registered changes to
the SET command. Now it will work for SET/DEL/FSET, just like
non-roaming geofences.
To opt out of these events, explicitly choose which event you
would like to register when you create the geofences.
For example:
NEARBY fleet FENCE COMMANDS set,del ROAM fleet * 5000
Will only fire off events from SET and DEL command.
Closes#597
This commit fixes a performance issue with the algorithm that
determines with geofences are potential candidates for
notifications following a SET operation.
Details
Prior to commit b471873 (10 commits ago) there was a bug where
the "cross" detection was not firing in all cases. This happened
because when looking for candidates for "cross" due to a SET
operation, only the geofences that overlapped the previous
position of the object and the geofences that overlapped the new
position where searched. But, in fac, all of the geofences that
overlapped the union rectangle of the old and new position should
have been searched.
That commit fixed the problem by searching a union rect of the
old and new positions. While this is an accurate solution, it
caused a slowdown on systems that have big/wild position changes
that might cross a huge number of geofences, even when those
geofences did not need actually need "cross" detection.
The fix
With this commit the geofences that have a "cross" detection
are stored in a seperated tree from those that do not. This
allows for a hybrid of the functionality prior and post b471873.
Fixes#583
This commit addresses issue #230, where an AOF file will sometimes
not load due to the file being padded with trailing zeros. It's
uncertain what is causing this corruption, but it appears to be
coming from outside of the tile38-server process. I suspect it's
due to some block store layer in Kubernetes/Docker cloud
environments.
This fix allows for Tile38 to start up by discovering the trailing
zeros while loading the AOF and safely truncating the file as to
not include the zeros in the future.
This commit fixes an issue that happens when running SCAN on a
collection that has objects with fields, causing field values
to be mismatched with their respective keys.
This only occured with json output, and is a regression from #534.
Fixes#569
This commit fixes an issue where the OUTPUT command requires
authentication when a server password has been set with
CONFIG SET requirepass. This was causing problems with clients
that use json responses, like the tile38-cli.
