If no regex type parameters are defined and a compiled pattern is
requested, the function will return a NULL value. This allows code that
directly calls the config_get_compiled_regex function to work without
doing additional checks for the presence of optional parameters.
With this change, it is no longer possible that the server version
is deallocated at the very moment it is read. There is still a race,
but it's mostly harmless.
The HintParser wrongly ignored linebreaks, causing parsing faults
e.g. parsing too far or accepting invalid comments. Now, the parser
detects a line break and terminates comments unless they started with
'/*'. Also, fixed a memory leak when parsing parameter-value-combinations.
Whenever a server which is a slave of an external master is detected, it
will be assigned the slave status. This will allow the status to be used
the way it was intended to be used.
The modutil_get_SQL()-function allocates storage, while
modutil_extract_SQL() does not. The strings given by the latter
are not 0-terminated so require a length limit when matched using
regexec().
This commit changes the used function in those cases where the
sql-string is not modified nor is the pointer saved for later use.
MXS-1282. The flags "-g=arglist" or "--debug=arglist" activate
the debug settings specified in the comma-separated list arglist.
Currently, the setting "disable-module-unloading", which prevents
modules (.so-files) from being unloaded at exit, is supported. This
allows Valgrind to produce line numbers for leak reports when the
memory was allocated in a module. The setting "enable-module-unloading"
is also available, but this is activated by default.
The debug arguments and their actions are defined in a structure
array, so adding more is straightforward.
The CREATE USER statement in the example document now also has a
password. This should make it more obvious that the same credentials must
work from all hosts.
The function now returns the compiled code or null or error. Also,
instead of capcount, it writes the ovector size. The ovector pointer
can be null. Removed the other config_get_compiled_regex()-function
and replaced it with the refactored function since they are almost
identical.
MXS-1067. The CCRFilter will now look at the hints in a write-type
query. The parameter-value combinations "ccr=match" and "ccr=ignore"
are recognized and will override any regex match and ignore settings.
For the hints to work, the HintFilter needs to be present in the filter
chain before the CCRFilter.
Also ran astyle and updated documentation.
The admin interface now uses HTTP BA authentication by default. This will
prevent unrestricted access to the REST API but the authentication is by
no means secure and the HTTPS mode for the REST API should be enabled for
all production systems.
The module commands can now produce JSON formatted output which is passed
to the caller. The output should conform to the JSON API as closely as
possible.
Currently, the REST API wraps all JSON produced by module commands inside
a meta-object of the following type:
{
"meta": <output of module command>
}
This allows the output to be JSON API conformant without modifying the
modules and allows incremental updates to code.
This is for backwards compatibility to allow current modules to use
the automatically compiled regex parameters. The enforcement should
be restored in a later version. A warning is output for every non-
enclosed regex.
Similar changes are also applied for QUOTED_STRING.
The timeout is hit very often if the cluster fixing takes some time. This
causes false positives so the timeout should be stopped before attempting
to fix the cluster.
The MySQL monitor replication_heartbeat table now uses the default storage
engine of the database when creating the table. Most of the time the
default is InnoDB which makes the table crash-safe.
