I'm not sure ... I just think they should be NSDebugLogs and not NSWarnLogs, since they are not warning about possible programming errors in the user code, but rather providing information which might be potentially useful for bug tracking. > > NSString +stringWithContentsOfFile should return nil if the file can't be > > opened ... it is up to the caller to decide what to do in that case, if > > this is perfectly acceptable or it is a major error, if it needs to be > > logged to stdout / stderr / a file / displayed in an alert panel / > > whatever, or if it can be ignored (as in the case of NSSavePanel). > > Well, it would be nice if the reason for the error could be stored > somewhere (like Unix's errno/errstring). I don't understand why you are assuming that +stringWithContentsOfFile returning nil is an error. The caller will assess that. In the case of NSSavePanel, for example, it's a perfectly valid condition. This is why the warning should be a NSDebugLog - off by default (as it is an undocumented and possibly unwanted warning about a 'maybe error', not an actual official error), and should only be turned on if you require it by using the appropriate --GNU-Debug stuff. _______________________________________________ Bug-gnustep mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-gnustep
