https://bugzilla.wikimedia.org/show_bug.cgi?id=23326 --- Comment #24 from Marco --- [editconflict] I had a look at a non-representative amount of PDF files taken from https://commons.wikimedia.org/wiki/Category:PDF_files_affected_by_MediaWiki_restrictions I encountered the following problems: * PDF renders fine on local machine but does not on the servers due to resource limitations. Ex: https://commons.wikimedia.org/wiki/File:Banner30a%C3%B1os.pdf & https://commons.wikimedia.org/w/index.php?title=File:Cox_and_box.pd -> There is no "real" fix for those files. One could higher the limits but this would had an impact on the server performance. * Corrupt PDF. Such as "File did not complete the page properly and may be damaged." or "Please notify the author of the software that produced this file that it does not conform to Adobe's published PDF specification." Ex: https://commons.wikimedia.org/wiki/File:Boca_y_su_historia.pdf & https://commons.wikimedia.org/wiki/File:Commons_upload_and_my_uploads_android_workflows.pdf -> Possible fix: Repair those files by bot or use another software which is less strict to process PDF files.

Which library restriction would you exactly like to work around here and how? With which exact incentive was this bug report reopened? We cannot easily fix broken damaged PDF files that were uploaded, so what is the expectation? (The feature requests in comment 16 should be separate bug reports as I write in comment 17). As I wrote before, a Ghostscript update very likely won't fix the issue in comment 0, and the different issue in comment 4 vanished. If you are after better error message propogation etc, please make that a different enhancement request. For the testcases in comment 0 and comment 4 on this bug report, I still consider this bug report INVALID. -- You are receiving this mail because: You are the assignee for the bug.

As domas said on some other bug, it doesn't matter whose fault it is; what matters is that the site is broken for the users (and readers). I think it's useful to discover that the problem lies in some PDF error, that might even be something users can "easily" solve themselves without waiting years for a bug fix; if we decide not to work around library restrictions, though, this doesn't make the problem disappear. In other words, what are users supposed to do in order to fix those PDFs? Are there standard commands to do so? We could for instance run a bot on Commons (this bug would be moved to Wikimedia>General), or at least make the error more useful. -- You are receiving this mail because: You are the assignee for the bug.

[Bug 23326] PDF image extraction fails - upgrade ghostscript
https://bugzilla.wikimedia.org/show_bug.cgi?id=23326 --- Comment #17 from Andre Klapper --- I think there is a misunderstanding here. We are responsible for MediaWiki and this is the canonical, "upstream" bugtracker for MediaWiki, so we of course accept reports and fix bugs for it. So far I have no reason to not believe the output of GhostScript that the specific PDF file is invalid. Again, if you think that GhostScript is wrong, the GhostScript developers need to be contacted "upstream", but I haven't seen any indication that it's a bug in GS so far. We use 3rd party software in many places (like PDF handling) to not reinvent the wheel (the related term is "downstream" - just mentioning the concept here, as I don't know how much open source background you have). > I suggested that perhaps we should use pdfimages (which does work) > instead of ghostscript (which is overly picky). That's worth a separate enhancement request, please file it in this Bugzilla so it can be considered. > But if the file is indeed broken, then Ghostscript should be used > as a validator during upload and refuse to accept this broken file. That's another pretty good idea, and worth another separate request. :) In general only one issue per report should be handled, and this report is about a specific PDF file testcase that does not show a thumbnail, and from all I know so far the reason is that the PDF file is broken, so there's nothing to do server-/software-side (yet) for Wikimedia developers. Hence I closed this as INVALID. This does not mean that things could not be improved in several ways via several involved parties in the long run, but that's out of scope for this specific issue. -- You are receiving this mail because: You are the assignee for the bug.

https://bugzilla.wikimedia.org/show_bug.cgi?id=23326 --- Comment #16 from Lars Aronsson --- "Ghostscript says the PDF file is broken and we use Ghostscript." With that logic, you can say "and we use Mediawiki 1.5", and stop improving anything. Why should we report bugs anymore? Already in comment 1, I suggested that perhaps we should use pdfimages (which does work) instead of ghostscript (which is overly picky). But if the file is indeed broken, then Ghostscript should be used as a validator during upload and refuse to accept this broken file. -- You are receiving this mail because: You are the assignee for the bug.

That's why I tested with the old PDF.
> That doesn't remove this bug
This report covers a few things. One is the problem that sometimes thumbnails
are not created for PDF files that Ghostscript considers to be invalid.
If this report is about the aspect "Provide some error message in the browser"
then it is not fixed, indeed, but I consider this aspect ("Expose readable
error messages in the browser" to be covered in bug 23831 already.
> The original PDF still displays
> properly in other software, so it is not broken.
So far the issue was the missing thumbnail, not how the PDF itself displays in
other software. Ghostscript says the PDF file is broken and we use Ghostscript.
I can imagine that other software is more forgiving.
If you know that the PDF file is not broken and hence consider the error
message in GhostScript wrong or misleading it would be best to discuss this
with the GhostScript developers. See the link in comment 13.

Warning: File has unbalanced q/Q operators (too many q's)
This file had errors that were repaired or ignored.
Please notify the author of the software that produced this

Hence I don't see any valid bug report here and nothing that could fixed on
Wikimedia's side. => Closing as INVALID.
A bug report should be filed against the tool the PDF was created with

If anybody thinks that GhostScript should be more forgiving, feel free to
report a request at http://bugs.ghostscript.com/ .
== Testcase in Comment 4 ==
No problems reproducible, thumbnail shown, no issues in Ghostscript. Might have
been a different issue that somehow disappeared.

Hmm, doesn't seem to be solved by the 8.71 upgrade (bug 26388), and this isn't
fixed by 9.04 either ("Error: /syntaxerror in -file-GPL Ghostscript 9.04:
Unrecoverable error, exit code 1"), so it doesn't seem likely that 9.05 is
going to fix this (bug 36580). Someone should probably test this with the very
latest version of Ghostscript, and if it's broken there, too, report a bug
upstream (see http://www.ghostscript.com/ )

[Bug 23326] PDF image extraction fails
https://bugzilla.wikimedia.org/show_bug.cgi?id=23326 Bawolff changed: What|Removed |Added CC||bawolff...@gmail.com --- Comment #2 from Bawolff 2010-04-27 07:06:25 UTC --- The error message makes it slightly sound like a font problem maybe(?) since according to the ghostscript faq ( http://pages.cs.wisc.edu/~ghost/doc/gnu/7.05/Issues.htm ): When CIDFont-CMap pair required by PDF file is not available GS fails with: /undefinedresource in --findresource-- and theres all sorts of font related stuff on the operhand stack, but i don't know much about pdfs, so that is a wild geuss. --- Anyways, here's the actual output from ghostscript when run on the command line (page 1 seems to print fine before it all blows up): Processing pages 1 through 4. Page 1 Substituting CID font resource/Adobe-Identity for /Arial.

[Bug 23326] PDF image extraction fails
https://bugzilla.wikimedia.org/show_bug.cgi?id=23326 --- Comment #1 from Lars Aronsson 2010-04-26 12:08:18 UTC --- On the Commons:Village_pump I was told how to view the error message (this was not trivial and leaves room for improvement). Apparently: Error creating thumbnail: GPL Ghostscript 8.61: Unrecoverable error, exit code 1 convert: no decode delegate for this image format `/tmp/magick-XXP4reva'. However, the offline PDF viewer "evince" that comes with Ubuntu Linux had no problem to view this PDF (images+text), and "pdfimages" also succeeds to extract the images, so it should be possible with free software. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.
