RE: write-region is mishandling an error
Possibly, I don't have the tools you speak of to tell. But then where is the data going? If the filename was simply being truncated but the data was still being written then I suppose I'd believe no 'error' occurred; that the OS simply sees the : as a file name terminator and continues successfully. But the file is empty. So it seems I'm also being asked to believe that subsequent write operations are also not getting errors. Being a programmer myself I can't help but find a claim that data is being discarded by a modern OS without error hard to believe. -Original Message- From: Richard Stallman [mailto:[EMAIL PROTECTED] Sent: Friday, February 09, 2007 8:23 AM To: Richard Bielawski Cc: emacs-pretest-bug@gnu.org Subject: Re: write-region is mishandling an error Which creates an empty file named Test at 12 and no error occurs.

write-region is mishandling an error
I couldn't get my data into a file using with-temp-file. All I got was an empty file. I eventually traced this command (with-temp-file Test at 12:05.txt (insert Hello)) down to * write-region(1 5 Test at 12:05.txt nil 0) Which creates an empty file named Test at 12 and no error occurs. Initially I didn't notice that the filename was truncated. Once I did I realized that : is illegal in a file name. Some kind of error must be occurring that isn't being reported. Turning debug-on-error on didn't show an error either.
