* Start on lua scripting
* Implement evalsha, script load, script exists, and script flush
* Type conversions from lua to resp/json.
Refactor to make luastate and luascripts persistent in the controller.
* Change controller.command and all underlying commands to return resp.Value.
Serialize only during the ouput.
* First stab at tile38 call from lua
* Change tile38 into tile38.call in Lua
* Property return errors from scripts
* Minor refactoring. No locking on script run
* Cleanup/refactoring
* Create a pool of 5 lua states, allow for more as needed. Refactor.
* Use safe map for scripts. Add a limit for max number of lua states. Refactor.
* Refactor
* Refactor script commands into atomic, read-only, and non-atomic classes.
Proper locking for all three classes.
Add tests for scripts
* More tests for scripts
* Properly escape newlines in lua-produced errors
* Better test for readonly failure
* Correctly convert ok/err messages between lua and resp.
Add pcall, sha1hex, error_reply, status_reply functions to tile38 namespace in lua.
* Add pcall test. Change writeErr to work with string argument
* Make sure eval/evalsha never attempt to write AOF
* Add eval-set and eval-get to benchmarks
* Fix eval benchmark tests, add more
* Improve benchmarks
* Optimizations and refactoring.
* Add lua memtest
* Typo
* Add dependency
* golint fixes
* gofmt fixes
* Add scripting commands to the core/commands.json
* Use ARGV for args inside lua
Performance gains for pipelining commands over the network.
Using tile38-benchmark and the -P flag it's possible to see 2x-10x boost
in requests per second.
Enabled TCP keepalive packets to determine if the connection is still
valid, and terminate if needed. It also helps with maintaining idle
connections.
Default to 300 seconds and can be changed by:
CONFIG SET keepalive 300
addresses #145: clients not being cleaned up properly
CLIENT LIST
CLIENT SETNAME name
CLIENT GETNAME
CLIENT KILL [ip:port] [ID client-id] [ADDR ip:port]
The CLIENT LIST command returns
One client connection per line (separated by LF)
Each line is composed of a succession of property=value
fields separated by a space character.
id: an unique 64-bit client ID
addr: address/port of the clien
age: total duration of the connection in seconds
idle: idle time of the connection in seconds
name: the name of the client
Suggested by @UriHendler, closes#139
Using the tile38-cli, the TTL command omitted the ttl value from the
json response.
For example:
127.0.0.1:9851> TTL my ufo
{"ok":true,"elapsed":"5.57µs"}
Is now fixed to show
127.0.0.1:9851> TTL my ufo
{"ok":true,"ttl":-1,"elapsed":"5.57µs"}
Where "ttl" is the remaining time before the object is is deleted.
The value -1 means that the object is available, but does not have
an expiration.
Thanks @phulst for finding this bug. closes#116
JSET key id path value [RAW]
JGET key id path [RAW]
JDEL key id path
Allows for working with JSON strings, for example:
JSET user 901 name Tom
JGET user 901
> '{"name":"Tom"}'
JSET user 901 name.first Tom
JSET user 901 name.last Anderson
> '{"name":{"first":"Tom","last":"Anderson"}'
JDEL user 901 name.last
> '{"name":{"first":"Tom"}'
All commands use the GJSON path syntax, for more information:

Getting JSON: https://github.com/tidwall/gjson
This addresses an issue #73 that @huangpeizhi discovered while using
Tile38 in production where AOFSHRINK sometimes corrupts the database
causing the server to not start the next time.
