Thanks to Itamar Haber for bug report and test case to reproduce.

antirez fb53459ce8 Lua debugger: default behavior of "list" command changed. 
Now it lists code around the current position by default. Can list any
other part using other arguments, but a new "whole" command was added in
order to show the whole source code easily.

antirez e386cd8ccf Lua debugger: clear end of session protocol. 
When the debugger exits now it produces an <endsession> tag that informs
redis-cli (or other debugging clients) that the session terminated.
This way the client knows there is yet another reply to read (the one of
the EVAL script itself), and can switch to non-debugging mode ASAP.

antirez e6eb6eadec Lua debugger: try to eval as expression first. 
It's handly to just eval "5+5" without the return and see it printed on
the screen as result. However prepending "return" does not always result
into valid Lua code. So what we do is to exploit a common Lua community
trick of trying to compile with return prepended, and if compilation
fails then it's not an expression that can be returned, so we try again
without prepending "return". Works great apparently.

antirez 1b5d24eb2b Scripting: fix redis.call() error reporting. 
Arguments arity and arguments type error of redis.call() were not
reported correctly to Lua, so the command acted in this regard like
redis.pcall(), but just for two commands. Redis.call() should always
raise errors instead.

antirez ff6d296000 Scripting: ability to turn on Lua commands style replication globally. 
Currently this feature is only accessible via DEBUG for testing, since
otherwise depending on the instance configuration a given script works
or is broken, which is against the Redis philosophy.

antirez ebaa9226ee Scripting: fix error reporting of many Redis provided functions. 2015-10-30 12:06:09 +01:00
antirez 2dabf82d5f Fix call() FORCE_REPL/AOF flags setting. 
This commit also inverts two stanzas of the code just becuase they are
more logical like that, not because currently it makes any difference.

antirez a3e8de0430 Lua script selective replication WIP. 2015-10-30 12:06:08 +01:00
antirez fc38235664 Scripting: single commands replication mode implemented. 
By calling redis.replicate_commands(), the scripting engine of Redis
switches to commands replication instead of replicating whole scripts.
This is useful when the script execution is costly but only results in a
few writes performed to the dataset.

Morover, in this mode, it is possible to call functions with side
effects freely, since the script execution does not need to be
deterministic: anyway we'll capture the outcome from the point of view
of changes to the dataset.

In this mode math.random() returns different sequences at every call.

If redis.replicate_commnads() is not called before any other write, the
command returns false and sticks to whole scripts replication instead.
