This syncs lua-cmsgpack with the mattsta/lua-cmsgpack upstream. Fixes #2161

zmalloc(0) cauesd to actually trigger a non-zero allocation since with standard libc malloc we have our own zmalloc header for memory tracking, but at the same time the returned pointer is at the end of the block and not in the middle. This triggers a false positive when testing with valgrind. When the inline protocol args count is 0, we now avoid reallocating c->argv, preventing the issue to happen.

Basically: test to make sure we can load cmsgpack and do some sanity checks to make sure pack/unpack works properly. We also have a bonus test for circular encoding and decoding because I was curious how it worked.

Main reasons for upgrade: - Remove a warning when building Redis - Add multi pack/unpack - Improve memory usage and use Lua allocator properly - Fix some edge case encoding/decoding bugs

clang doesn't like "extern inline" when no definition is given right away.

cjson calls isinf, but some Solaris versions don't have isinf even with the attempted fix we have in deps/Makefile. We can harmlessly include the Redis solarisfixes.h header to give cjson proper isinf. Note: cjson has a compile-time setting for using their own defined isinf, but the Redis definition in solarisfixes.h is more complete. Fixes antirez#1620

The new cjson has some improvements over our current version including increased platform compatability, a new resource limit to restrict decode depth, and better invalid number handling. One minor change was required to deps/Makefile because this version of cjson doesn't export itself globally, so we added a quick little define of -DENABLE_CJSON_GLOBAL. cjson now has an optional higher performing float parsing interface, but we are not including it (g_fmt.c, dtoa.c) because it requires endianness declaration during compile time. This commit is exactly lua_cjson.c from 2.1.0 with one minor change of altering the two Lua includes for local search instead of system-wide importing.

Two simple decode tests added mainly to check that the 'cjson' global gets registered and is usable.

A few people have written custom C commands because bit manipulation isn't exposed through Lua. Let's give them Mike Pall's bitop. This adds bitop 1.0.2 (2012-05-08) from http://bitop.luajit.org/ bitop is imported as "bit" into the global namespace. New Lua commands: bit.tobit, bit.tohex, bit.bnot, bit.band, bit.bor, bit.bxor, bit.lshift, bit.rshift, bit.arshift, bit.rol, bit.ror, bit.bswap Verification of working (the asserts would abort on error, so (nil) is correct): 127.0.0.1:6379> eval "assert(bit.tobit(1) == 1); assert(bit.band(1) == 1); assert(bit.bxor(1,2) == 3); assert(bit.bor(1,2,4,8,16,32,64,128) == 255)" 0 (nil) 127.0.0.1:6379> eval 'assert(0x7fffffff == 2147483647, "broken hex literals"); assert(0xffffffff == -1 or 0xffffffff == 2^32-1, "broken hex literals"); assert(tostring(-1) == "-1", "broken tostring()"); assert(tostring(0xffffffff) == "-1" or tostring(0xffffffff) == "4294967295", "broken tostring()")' 0 (nil) Tests also integrated into the scripting tests and can be run with: ./runtest --single unit/scripting Tests are excerpted from `bittest.lua` included in the bitop distribution.

RDB EOF detection was relying on the final part of the RDB transfer to be a magic 40 bytes EOF marker. However as the slave is put online immediately, and because of sockets timeouts, the replication stream is actually contiguous with the RDB file. This means that to detect the EOF correctly we should either: 1) Scan all the stream searching for the mark. Sucks CPU-wise. 2) Start to send the replication stream only after an acknowledge. 3) Implement a proper chunked encoding. For now solution "2" was picked, so the master does not start to send ASAP the stream of commands in the case of diskless replication. We wait for the first REPLCONF ACK command from the slave, that certifies us that the slave correctly loaded the RDB file and is ready to get more data.

The old DEBUG POPULATE form for automatic creation of test keys is: DEBUG POPULATE <count> Now an additional form is available: DEBUG POPULATE <count> <prefix> When prefix is not specified, it defaults to "key", so the keys are named incrementally from key:0 to key:<count-1>. Otherwise the specified prefix is used instead of "key". The command is useful in order to populate different Redis instances with key names guaranteed to don't collide. There are other debugging uses, for example it is possible to add additional N keys using a count of N and a random prefix at every call.

This caused BGSAVE to be triggered a second time without any need when we switch from socket to disk target via the command CONFIG SET repl-diskless-sync no and there is already a slave waiting for the BGSAVE to start. Also comments clarified about what is happening.

Child now reports full info to the parent including IDs of slaves in failure state and exit code.

EWOULDBLOCK with the fdset rio target is returned when we try to write but the send timeout socket option triggered an error. Better to translate the error in something the user can actually recognize as a timeout.

We need to avoid that a child -> slaves transfer can continue forever. We use the same timeout used as global replication timeout, which is documented to also affect I/O operations during bulk transfers.

While the socket is set in blocking mode, we still can get short writes writing to a socket.
