I haven't supplied this patch in proper form yet, but this discussion relates to the patch. I would like to remind folks that on some platforms, one cannot just use "errno = 0". On those platforms calling a function is required to set errno. The point of patch 505846 is to "standardized" the "errno = " function, and secondarily provide a way to "get" the errno. This is done in pyport.h and "all modules" that use or set errno. (not as many as you might think) It's an ugly patch, requires a lot of changes to the core. I'm willing to make all the changes to the core as needed, once we figure out the best way to handle this issue is. In fact, it's this patch that is the principal cause of the "fork python ce" thread also recently discussed in this forum. See "Need advice: cloning python cvs for CE project" Windows CE doesn't allow setting errno. Neither does NetWare (CLIB). Is it worthwhile to discuss patch 505846 some more in this thread? Perhaps those who haven't read the comments on the patch have a clever solution? Or should I just clean up my patch, resubmit it and move on? I agree with Mark's post about keeping CE changes in the core. I'd rather do that. I submitted patch 505846 incorrectly and need to fix it.. But after it's submitted and if accepted, core developers would need to use Py_SetErrno instead of "errno = " And for extension developers. Using the macro would be nice, but it's less of an issue since CE and NetWare ports have to be done "by hand" anyway for these modules, we can make those changes as they're encountered. So .. discuss this, look for better insight, or resubmit the patch and move on? Thanks Brad Clements, bkc@murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax AOL-IM: BKClements
