Remove trailing comma in last value of `redisConnectionType` enum. This causes a compiler warning on Solaris compilers. I'd like to build this on Solaris with `-Werror`. However, due to the trailing comma, I cannot do that.
This PR removes the trailing comma, which should prevent it causing compiler warnings on any architecture.
Prevent buffer overflow when formatting the error
strncat might copy n+1 bytes (n bytes from the source plus a terminating nul byte).
Also strncat appends after the first found nul byte. But all we pass is
a buffer we might not have zeroed out already.
Closes#380

Not all code using hiredis can compile using '-std=c99', and/or not all users are able to easily make that change to the build process of various open-source projects, so it is more pragmatic to choose a different identifier that does not impose this requirement.
Originally implemented by @abedra as part of #306.
In case a write or read times out, we force an error state, because we
can't guarantuee that the next read will get the right data.
Instead we need to reconnect to have a clean-state connection, which is
now easily possible with this method.
Major fix:
- `make install` now works properly
Minor fix:
- `make test` now works after `make 32bit` on a 64-bit platform
- added more automated travis tests
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
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
[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
[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
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/c92ef31bb632b3d0ad81Closes#260
Some environments require binding to specific source addresses instead
of letting the system determine which IP a connection should originate
from.
Closes#233
The struct timeval argument in redisConnectWithTimeout(),
redisConnectUnixWithTimeout(), redisSetTimeout(),
redisContextSetTimeout(), redisContextConnectTcp()
and redisContextConnectUnix() is never modified and can
therefore be marked as const.

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).
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.
This reverts commit 77540aa316. 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.
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.
To make sure that these functions can also be called from functions
other than command callbacks, the flag IN_CALLBACK is introduced that
holds whether the context is currently executing a callback. If so,
redisAsyncFree() and redisAsyncDisconnect() should delegate their task
to the reply processor to avoid segfaults.
When no reply object functions are defined, the reply type integer is
returned from redisGetReply(). This sets the *reply argument to the
consumed reply, where 0 means that it was not possible to consume a full
reply. With REDIS_REPLY_ERROR having the same value, there is no way to
tell the difference between an error reply and not consuming a reply.
When there is an I/O error, errno should be used to find out what is
wrong. In other cases, errno cannot be used. So, use an explicit type in
Hiredis to define the different error scenarios that can occur.
This allows users of the API to format a command without the need to
have all the sds functions included, only for free'ing the returned
wire-level command.
This removes the need to wrap an event_base pointer in the redisContext
struct and allows multiple connections to be used in a single
event_base. Also, use the *privdata argument to the provided callbacks
to curry the redisEvent struct around.
