2015-01-22Improve digit counting for multibulk creationMatt Stancliff
This replaces the old intlen() implementation with a slightly faster way of counting digits. Implementation taken from the same place where digits10() in redis/src/util.c came from. The old 'intlen' allowed negative inputs, but no usage in hiredis was passing negative numbers, so that ability is removed. Also, the new implementation can count higher (uint64_t) instead of limited to just int as before. Fixes #295 by replacing implementation

2015-01-05Fix errno error buffers to not clobber errorsMatt Stancliff
The strerror_r API has two flavors depending on system options. The bad flavor uses a static buffer for returning results, so if you save the pointer from strerror_r, the string you're referencing becomes useless if anybody else calls strerror_r again The good flavor does what you expect: it writes the error to your buffer. This commit uses strerror_r directly if it's a good version or copies the static buffer into our private buffer if it's a bad version. Thanks to gemorin for explaining the problem and drafting a fix. Fixes #239
2015-01-05Refactor reading code into read.ctzickel
Makes hiredis reading functions easier to include in external projects [fixed all merge conflicts against current version] Closes #249
2015-01-05Fix redisAppendCommand error resultMatt Stancliff
Previously, redisvAppendCommand() would return OOM even with formatting errors. Now we use OTHER with an error string telling the user the error was formatting related, not memory related. This also fixes a potentially worse bug where were would pass error result of -1 as an actual length to another function taking an unsigned length, which would result in crash/overallocation/errors. Now for that case, we just return an error immediately and stop processing the command. Fixes #177
2015-01-05Add empty pointer check in error cleanupNanXiao
If realloc fails, the curargv will be NULL. Closes #253
2015-01-05Add error check in redisContextInitNanXiao
Check whether the obuf or reader is empty: if one of the items is empty, free the redisContext.
2015-01-05Fix redisvFormatCommand format parsingNan Xiao
Flags can occur in any order in format string, so we can't assume any order. In original code, the redisvFormatCommand can process " %#+d" correctly, but can't process "%+#d". Closes #257
2015-01-05Add API to free hiredis (sds) formattingsMatt Stancliff
External callers may not know about sdsfree, so let's give them an easy way to know how to free their sds result.
2015-01-05Add API to free hiredis (char *) formattingsMareq
[Cleaned up: - name of function: freeRedis... -> redisFree... - return value of function (free doesn't return anything) - parameter type for function. - we don't need to free a char**, the char** is just for returning from the assignment functoin.] Closes #250
2015-01-05Add support for SO_REUSEADDRmike
[This introduces some new API functions.] * Adds new flag to the connection context indicating SO_REUSEADDR should be set. * Adds max number of retries constant for when connect() hits EADDRNOTAVAIL. * Adds new function, redisAsyncConnectBindWithReuse(), letting clients enable this functionality. [Removed trailing whitespace in new header lines.] Closes #264
2015-01-05Improve calloc() correctnessjinguoli
[It doesn't _actually_ matter, but technically the order argument is: (number of items, size of items)] Closes #279
2015-01-05Improve redisAppendCommandArgv performancemichael-grunder
OK, perhaps the second time is a charm. I forgot that I had hiredis forked from a long time ago, so the initial pull request was hosed. :) * Pulled in sdscatfmt() from Redis, and modified it to accept a size_t (%T) style format specifier. * Pulled in sdsll2str() and sdsull2str() from Redis (needed by sdscatfmt). * Added a new method, redisFormatSdsCommandArgv() which takes and sds* as the target, rather than char* (and uses sdscatfmt instead of sprintf for the construction). I get roughly the following improvement: Old: 1.044806 New: 0.481620 The benchmark code itself can be found here: https://gist.github.com/michael-grunder/c92ef31bb632b3d0ad81 Closes #260
2014-05-29Less surprising behaviour.Daniel Melani
Make redisFree() and freeReplyObject() less surprising by behaving just like free(). That is, don't crash when passing in NULL.

2014-04-09Upgrade sds to latest versionantirez
SDS is now broken out of Redis into its own project, so include the latest version from the SDS repo. This is a backport of the Redis commit doing the same to the bundled hiredis: https://github.com/antirez/redis/commit/320fa02b9b48ee1c63d88db6344fc0d328e24853
2014-04-09Add new redisAppendFormatedCommand with testsAxel Etcheverry
Closes #202
2014-04-09Add redisConnectFd() and redisFreeKeepFd()Eddy Jansson
These allows for easier integration of hiredis with external code that wants to manage its fds, say for instance in a pool. Closes #223
2014-04-08Add ability to bind source address on connectMatt Stancliff
Some environments require binding to specific source addresses instead of letting the system determine which IP a connection should originate from. Closes #233
2013-07-10Mark the timeout parameter as const in various functionsNoah Williamsson
The struct timeval argument in redisConnectWithTimeout(), redisConnectUnixWithTimeout(), redisSetTimeout(), redisContextSetTimeout(), redisContextConnectTcp() and redisContextConnectUnix() is never modified and can therefore be marked as const.

2012-08-21On stack buffer to read replies set to 16k (was 2k).antirez
It was verified experimentally that this value, on Linux kernels, provides better performances compared to the 2k value. However larger values apparently don't produce any noticeable effect on performances.
2012-08-21Max depth of multi-bulk reply moved from 2 to 7.antirez
Hiredis can handle multi bulk replies with a fixed (hardcoded) level of nesting. This should be changed in the future in order to avoid hardcoded limits. As a quick fix this commit moves the max nesting from 2 to 7, so that there are no problems when processing replies from the SLOWLOG command, from Redis Sentinel, or generated by Redis Lua Scripts (that are allowed to generate replies with any level of nesting).
2012-08-21Configurable reader max idle buffer size.antirez
Hiredis used to free unused redisReader buffers bigger than 16k. Now this limit is configurable (see the documentation updated by this commit) in order to allow working with big payloads without incurring to speed penalty.

2011-07-09Abort on invalid formatPieter Noordhuis
There is no way we can guess the width of the argument when we cannot infer its type from the format specifier.

2011-06-19Revert "Add function to retrieve formatted reply"Pieter Noordhuis
This reverts commit 77540aa31694aa1e14d41f60a0452e49a2fed86a. The change in buffer strategy is too large to put in a minor release. It is put in a separate branch in the meantime, so it can be refined and released together with a minor version bump.
2011-06-09Fix for issue #45Pieter Noordhuis
2011-05-05Add function to retrieve formatted replyPieter Noordhuis
This is done by only truncating the read buffer once a full reply has been read. The buffer is no longer truncated halfway through reading a reply. In addition: pass offset/length of protocol and content via the read tasks.
