Fix ProtocolError
This commit attempts to fix hiredis such that a recoverable write error
will be retried rather than throwing a hard error.
Since our read/write functions are now behind function pointers, we
specify semantically that a return value of < 0 is a hard error, 0 a
recoverable error, and > 0 a success.
Our default `redisNetRead` function was already doing something similar
so this also improves code consistency.
Resolves #961

Currently, hiredis supports TCP/SSL/Unix, all of the connection types
use a single FD(int), close() is enough to close a connection. For the
further step, introduce .close method for redisContextFuncs, this
allows to close a complex connection context, for example RDMA.

Wrapping multi-line macros in do...while(0) statement prevents
potential dangling else problem.

RESP3 allows sending commands in parallell with pubsub handling
and these commands might get responded with a REDIS_REPLY_ARRAY.
This conflicts with the pubsub response handling for RESP2 and
results in a faulty state when using RESP3.
Add functionality to keep track of PUSH/RESP3 support on the connection
and only expect the message type REDIS_REPLY_PUSH as subscribe messages
when once seen.

When set hiredis will not automatically free replies in an async context, and the replies must be freed instead by the user.

We need to allow our users to use redisContext->privdata as context
for any RESP3 PUSH messages, which means we can't use it for managing
SSL connections.
Bulletpoints:
* Create a secondary redisContext member for internal use only called
privctx and rename the redisContextFuncs->free_privdata accordingly.
* Adds a `free_privdata` function pointer so the user can tie allocated
memory to the lifetime of a redisContext (like they can already do
with redisAsyncContext)
* Enables SSL tests in .travis.yml

Small change to the logic introduced in #839
|
|
Add an additional timeout so the user has a convenient way of controlling distinct connect and command timeouts
|
|
Proper support for RESP3 PUSH messages.
By default, PUSH messages are now intercepted and the reply memory freed.
This means existing code should work unchanged when connecting to Redis
>= 6.0.0 even if `CLIENT TRACKING` were then enabled.
Additionally, we define two callbacks users can configure if they wish to handle
these messages in a custom way:
void redisPushFn(void *privdata, void *reply);
void redisAsyncPushFn(redisAsyncContext *ac, void *reply);
See #825

Port RESP3 support from Redis.
|
|
Use _MSC_VER (instead of _WIN32) for things that are specific for
Visual Studio.
Also remove #include <winsock2.h> from hiredis.h, as it leaks too
many symbols and defines into the global namespace, which is
undesirable for a public interface header. Anyone who uses the
the affected parts of the hiredis API needs to include the
appropriate headers anyway in order to declare struct timeval
variables.

This corresponds to commits d5c54f0b..bea09a7f in the redis repository.

|
With this change, Hiredis builds with MinGW and runs on Windows.

|
The redisFD type should be equal to the system native socket file
desciptor type (for POSIX, this is a plain int).
We also introduce the REDIS_INVALID_FD value, which maps to -1 on POSIX
systems.

|
This reduces the boilerplate of all the redisConnectXXX functions, and
allows us to provide more connection options in the future.
|

|
This retrieves the actual error which occurred, as getsockopt is not
always reliable in this regard.
|
|
SONAME bumped to 0.14 because we've broken ABI compatibility with 0.13.x
|
|
Since _GNU_SOURCE is now guaranteed to be unset, it is no longer
necessary to support the GNU-specific version of strerror_r.
Drop __redis_strerror_r from the header, and call strerror_r directly.
This breaks any external users of this macro, but they shouldn't have
been using it in the first place.

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
