One of the things on my todo list for 1.2 is to unify the various sets of custom error codes in pacemaker into a single set of codes with a single error-to-text function. LSB and OCF return codes are the obvious exception here.
Where possible I will be using standard system error codes from errno.h[1] Any custom errors[2] will be chosen well above the existing range to avoid conflicts. This should simplify error reporting, since there is plenty of redundancy within some APIs and things like "not found" and "not connected" will become consistent across APIs. It will also allow us to push most of the error-to-text code into the standard strerror() function - less custom code means less bugs. To ease the task of programs using the old enum values, we will begin providing <crm/compatability.h> This will contain the new values for the old error names. In the future, other deprecated macros and functions will also move here, utilising the __deprecated__ compiler attribute where possible. It is important to note however, the header must be explicitly pulled in by anyone that wants to use it. For non-C programs, it provides value as a conversion guide. -- Andrew [1] With the caveat that we'll be negating them. Eg. -EIO instead of EIO. [2] It looks like there should only be half a dozen or so. _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
