Functionally the same, but makes cherry picking simpler.

If we run a long latency session and want to Ctrl-C out of it, it's nice to still get the summary output at the end.

Lua scripts are executed in the context of the currently selected database (as selected by the caller of the script). However Lua scripts are also free to use the SELECT command in order to affect other DBs. When SELECT is called frm Lua, the old behavior, before this commit, was to automatically set the Lua caller selected DB to the last DB selected by Lua. See for example the following sequence of commands: SELECT 0 SET x 10 EVAL "redis.call('select','1')" 0 SET x 20 Before this commit after the execution of this sequence of commands, we'll have x=10 in DB 0, and x=20 in DB 1. Because of the problem above, there was a bug affecting replication of Lua scripts, because of the actual implementation of replication. It was possible to fix the implementation of Lua scripts in order to fix the issue, but looking closely, the bug is the consequence of the behavior of Lua ability to set the caller's DB. Under the old semantics, a script selecting a different DB, has no simple ways to restore the state and select back the previously selected DB. Moreover the script auhtor must remember that the restore is needed, otherwise the new commands executed by the caller, will be executed in the context of a different DB. So this commit fixes both the replication issue, and this hard-to-use semantics, by removing the ability of Lua, after the script execution, to force the caller to switch to the DB selected by the Lua script. The new behavior of the previous sequence of commadns is to just set X=20 in DB 0. However Lua scripts are still capable of writing / reading from different DBs if needed. WARNING: This is a semantical change that will break programs that are conceived to select the client selected DB via Lua scripts. This fixes issue #1811.

It is more straightforward to just test for a numerical type avoiding Lua's automatic conversion. The code is technically more correct now, however Lua should automatically convert to number only if the original type is a string that "looks like a number", and not from other types, so practically speaking the fix is identical AFAIK.

The new check-for-number behavior of Lua arguments broke users who use large strings of just integers. The Lua number check would convert the string to a number, but that breaks user data because Lua numbers have limited precision compared to an arbitrarily precise number wrapped in a string. Regression fixed and new test added. Fixes #1118 again.

Behrad Zari discovered [1] and Josiah reported [2]: if you block and wait for a list to exist, but the list creates from a non-push command, the blocked client never gets notified. This commit adds notification of blocked clients into the DB layer and away from individual commands. Lists can be created by [LR]PUSH, SORT..STORE, RENAME, MOVE, and RESTORE. Previously, blocked client notifications were only triggered by [LR]PUSH. Your client would never get notified if a list were created by SORT..STORE or RENAME or a RESTORE, etc. Blocked client notification now happens in one unified place: - dbAdd() triggers notification when adding a list to the DB Two new tests are added that fail prior to this commit. All test pass. Fixes #1668 [1]: https://groups.google.com/forum/#!topic/redis-db/k4oWfMkN1NU [2]: #1668

Replication is totally broken when a slave has this option, since it stops accepting updates from masters. This fixes issue #1434.

I'm not sure if while the visibility is the inner block, the fact we point to 'dbuf' is a problem or not, probably the stack var isx guaranteed to live until the function returns. However obvious code is better anyway.

The lua_to*string() family of functions use a non optimal format specifier when converting integers to strings. This has both the problem of the number being converted in exponential notation, which we don't use as a Redis return value when floating point numbers are involed, and, moreover, there is a loss of precision since the default format specifier is not able to represent numbers that must be represented exactly in the IEEE 754 number mantissa. The new code handles it as a special case using a saner conversion. This fixes issue #1118.

If we are in the signal handler, we don't want to handle the signal again. In extreme cases, this can cause a stack overflow and segfault Redis. Fixes #1771

When we are blocked and a few events a processed from time to time, it is smarter to call the event handler a few times in order to handle the accept, read, write, close cycle of a client in a single pass, otherwise there is too much latency added for clients to receive a reply while the server is busy in some way (for example during the DB loading).

When the listening sockets readable event is fired, we have the chance to accept multiple clients instead of accepting a single one. This makes Redis more responsive when there is a mass-connect event (for example after the server startup), and in workloads where a connect-disconnect pattern is used often, so that multiple clients are waiting to be accepted continuously. As a side effect, this commit makes the LOADING, BUSY, and similar errors much faster to deliver to the client, making Redis more responsive when there is to return errors to inform the clients that the server is blocked in an not interruptible operation.

When scanning the argument list inside of a redis.call() invocation for pre-cached values, there was no check being done that the argument we were on was in fact within the bounds of the cache size. So if a redis.call() command was ever executed with more than 32 arguments (current cache size #define setting) redis-server could segfault.
