Subject: Patch to report errors opening PNG image files
Download (untitled) / with headers
text/plain 1.2k does not die when an open() fails, resulting in mysterious undefined value errors. The attached patch adds an "or die()" to the open() and removes a possibly duplicate open. Also, here is a series of other similar lines of code that don't happen to be biting me (yet): c:\perl\site\lib\PDF\API2\Resource\ColorSpace\Indexed\ open($fh,$file); c:\perl\site\lib\PDF\API2\Resource\Font\ : open(INF,$file); c:\perl\site\lib\PDF\API2\Resource\Font\ : open($fh,$file) || return undef; c:\perl\site\lib\PDF\API2\Resource\XObject\Image\ : open($fh,$file); c:\perl\site\lib\PDF\API2\Resource\XObject\Image\ : open($fh,$file); c:\perl\site\lib\PDF\API2\Resource\XObject\Image\ : open(INF,$file); c:\perl\site\lib\PDF\API2\Resource\XObject\Image\ : open($self->{fh},"< $file"); c:\perl\site\lib\PDF\API2\ : open($fh,"$dir/PDF/API2/Resource/unipaper.txt"); c:\perl\site\lib\PDF\API2\ : open($fh,"$dir/PDF/API2/Resource/uniglyph.txt"); c:\perl\site\lib\PDF\API2\ : open($fh,"$dir/PDF/API2/Resource/unicolor.txt");

I could get behind this request to not silently err on failure to open a file. The only question is whether a "die" is the best thing to do, or should some recovery attempt take place to limp along (give an error message in that case)? Adding an "or die" to all file operations (at least, opens and closes) shouldn't be rocket science, if there are any such cases still open. To add a comment to this thread, just email bug-PDF-API2 [at] with subject line [ #33970]. Note 1 space between org and #, and the [ ] around the whole subject. Nothing else. If you don't follow this format carefully, you will end up creating a new bug report! HTML formatting within the body does not work.

I bet you wouldn't have guessed that it would take 8.5 years for this to get done! These checks will be in the next release (2.029).
