The Avro libraries appear to sometimes overwrite the CMake
variables. Patching out the code that looks for the libraries should
prevent the library from ever being linked against the snappy libraries.
The documentation stated that at most `max_sescmd_history` commands were
kept but in reality the number of commands kept in the history was one
command smaller than what was documented.
Moved hintfilter documentation to the correct place and cleaned it
up. Added a note at the start of the syntax documentation about the
behavior of the hint parsing to warn users of possible unexpected
behavior. The hint parsing could really use some refactoring to make it
more manageable which is why the preliminary fix version of the bug will
be 2.4.
By repeatedly doing reads instead of one read per second, it is more
likely that MXS-2311 is reproduced. This is still not a deterministic
process but in theory it can reproduce the problem.
If an ignorable packet was followed by more than one queued packets, they
would all get routed in the same batch. This would cause unexpected
replies from the server if multiple ignorable packets were queued up.
Using a void return value as an integer results in undefined behavior.
apparently in this case it doesn't translate into a crash and instead only
manifests itself when all the planets align.
In this mode the compare program does a sanity check where it compares the
output of a classifier when a statement is classified multiple times. The
main use-case for this is to get the verbose output generated when the -v3
option is added, not the sanity check itself.
If the schema parsing fails due to an error, add the actual JSON to the
error string. This helps solve any problems that might occur due to
malformed JSON on the sending end.
The default ECMAScript syntax appears to be broken on CentOS 7 which
effectively prevents its use in most cases. A more reliable alternative
would be to use the bundled PCRE2 library but the basic POSIX regular
expressions seem to work.
The script generates the required .avsc files without requiring a direct
connection to the database. This makes it easier to generate schemas in
more secure installations where direct access and installing dependencies
might not be easy.
