log.cc:this_unit.slogger depends upon logger.cc:this_unit.ident.
Depending on which one is destructed first, there will be a crash
or then not.
It seems that the destruction order when returning from main()
is not necessarily the same as that when calling exit() in main,
as this bug is triggered with compilers versions and not with other.
Having helper methods that combine the index position search and value
extraction make it easier to deal with results that have a lot of fields
e.g. the output of SHOW SLAVE STATUS.
If normal authentication fails and a PAM service is defined, PAM authentication
is attempted. Separate services can be set for read-only users and admin-level
users.
Increasing counter sizes from int to long for averages.
Rename random functions to end with _co instead of _exclusive to
indicate range [close, open[, and to allow future suffixes oc, cc and oo.
Previously, runtime monitor modifications could directly alter monitor fields,
which could leave the text-form parameters and reality out-of-sync. Also,
the configure-function was not called for the entire monitor-object, only the
module-implementation.
Now, all modifications go through the overridden configure-function, which calls the
base-class function. As most configuration changes are given in text-form, this
removes the need for specific setters. The only exceptions are the server add/remove
operations, which must modify the text-form serverlist.
Sometimes that's what you want, but primarily for completeness'
sake and it makes AUTO more sensical as it essentially chooses
beteen DIRECT and QUEUED mode.
The QueryResult-object remembers if a conversion failed. This makes checking
for errors more convenient, as just one check per row is required. The conversion
functions always return a valid value.
A multi HTTP GET can now be performed so that the caller
drives the polling of results.
This can now be used so that inside a monitor worker, the delays
are handled using delayed calls. Consequently, the monitor worker
event loop can remain responsive even though the Clustrix nodes
are being polled.
