My attention was drawn to the log_error() stuff in controldata_utils.c by the fact that buildfarm member pademelon spit up on it. The reason for that compile failure is that pademelon's dinosaur of a compiler doesn't support __VA_ARGS__. I do not feel a need to get into a discussion about whether we should move our portability goalposts for the convenience of this commit, because there are other reasons why this is a crummy solution for error reporting:
* It uses elog() not ereport() for what seems a not-particularly-internal error, which among other things means that an entirely inappropriate errcode() will be reported. * It relies on strerror(errno), not %m, which may not work reliably even in elog() and certainly won't in ereport() (because of order-of-evaluation uncertainties). * Translatability of the error message in the frontend context seems a bit dubious; generally we let translators work with the whole string to be printed, not just part of it. * It's randomly unlike every single other place we've addressed the same problem. Everywhere else in src/common does it like this: #ifndef FRONTEND ereport(ERROR, (errcode(ERRCODE_PROGRAM_LIMIT_EXCEEDED), errmsg("out of memory"))); #else fprintf(stderr, _("out of memory\n")); exit(EXIT_FAILURE); #endif and I think that's what this needs to do too, especially in view of the fact that there are only two places that would have to be fixed anyway. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
