test_poll was calling poll_init() two times since it's already included in
init_test_env().
test_queuemanager was missing a bunch of frees. This doesn't fix it completely,
but removes most of the leaks and valgrind errors.
For the general case, regex matching simply will not do. The
regex becomes so hairy so it turns write-only, i.e. unmaintainable.
Regex matching is also slower than a handwritten custom parser.
TheBoundaryMatcher is not updated as it is likely it will be removed
altogether. A regex that accepts comments in all relevant places becomes
so hairy it is unmaintainable. It seems that the only working solution
would be to first remove all comments and then perform the regex.
Transaction boundaries can now be detected using regexes.
All else being equal, it gives a 10% performance improvement
compared to qc-based detection.
In a subsequent change, mysql_client.c will be modified to use
qc_get_trx_type_mask() instead of qc_get_type_mask().
Currently the use of regex matching is turned on using an
environment variable. That will change.
Moved some typedefs to router.h and server.h, changed a few
constants to these enums. Renamed some types in config.h to
remove "Gateway".
There are still some functions in the public header which are
only used in core, but they seem to fit the theme of public functions
so were not moved.
- All (but the printing/debug functions) are now in snake_case.
- Functions made const correct.
- All function prototypes now have named arguments.
Documentation still to be moved, and file possibly split into
include/mascale/server.h and server/core/maxscale/server.h
The MODULE_INFO is now the main object which is used by modules to convey
information to the MaxScale core. The MXS_MODULE name is more apt as it
now contains the actual module definition.
The old MODULES structure was moved into load_utils.c as an internal
implementation and was renamed so that it is not confused with the new
MODULE structure.
- Move docs from buffer.c to buffer.h
- Arguments made const-correct.
gwbuf_length
gwbuf_count
gwbuf_copy_data
- Boolean return values changes from int to bool.
gwbuf_add_property
- Meaningless returnvalue changed from int to void.
gwbuf_add_hint
- Unused function removed.
gwbuf_clone_transform
gwbuf_trim
gwbuf_clone cloned only the first buffer of a chain of buffers,
which never can be the desired outcome, while gwbuf_clone_all
cloned all buffers.
Now, gwbuf_clone behaves the way gwbuf_clone_all used to behave
and gwbuf_clone_all has been removed.
MXS-873 To prevent monitors and MaxAdmin from interfering with each other,
changes to the server status flags now happen under a lock. To avoid
interfering with monitor logic, the monitors now acquire locks to all
of their servers at the start of the monitor loop and release them
before sleeping.
Aligning the statistics object indices to cache line size reduces the CPU
overhead of gathering the statistics. This allows the statistics to more
accurately measure the polling system without the measurement affecting
the outcome.
