Since localtime is not thread-safe it should not be used in multithreaded
contexts. For this reason all calls to localtime were changed to localtime_r
in code where concurrency issues were possible.
Internal tests were left unchanged because they aren't multithreaded.
A buffer was allocated for strlen(event) characters leading to the
name always being truncated by one character. The use of a buffer was
unnecessary and was fixed by using the mon_get_event_name function directly.
Added maxadmin command to flush all logs to disk. This will allow tests
to gather all logs without having to wait for the logs to be flushed by
the log flusher thread.
The error message did not provide any useful information and was most of the
time a false positive due to EPOLL_RDHUP events calling the hangup function
of the DCB.
The bundled PCRE2 library will be built as a separate target and configuring
CMake no longer builds it. Instead, it will only be built when it is out of date.
This requires all targets to declare that they depend on the pcre2 target in
order for it to be built.
skygw_[enable|disable]_log has now been removed from the external
interface and priorities must instead be set using
mxs_log_set_priority_enabled(int priority, bool enabled). A bitmask
is already being updated, but internally and as used by the LOG_IF
macros, the actual enabling is still made using logfile ids.
The configuration entries have been replaced as follows:
log_messages -> log_notice
log_trace -> log_info
The old ones can be used, but cause a warning to be logged.
Similarily the maxadmin commands have been updated.
"[enable|disable] log ..." works as expected, but there will be
a message about it being deprecated. Instead there is now a
[enable|disable] log-priority err|warning|notice|info|debug
command that should be used instead.
skygw_logmanager_init renamed to mxs_log_init and skygw_logmanager_done
renamed to mxs_log_finish. skygw_logmanager_exit removed alltogether as
all it did was to call skygw_logmanager_done. That appears to have been
a source for confusion as in many places a call to skygw_logmanager_done
was followed by a call to skygw_logmanager_exit. In addition, the function
skygw_log_done was removed from the header, since it lacked an
implementation.
The change to the mysql.user table in MySQL 5.7 caused MaxScale to stop
working with it. This commit adds functionality that checks which version of
the user data query should be made. It also moves common code related to
server version strings to server.c
With only one log-file no arguments are needed. The maxadmin command
'flush log' still accepts all the previous arguments, but warns about
them being deprecated.
