[Bug 1126427] Re: LCMS2 needs multi-threading fixes to work with the new Ghostscript 9.07
As decided on in #ubuntu-desktop just now, we'll not ship this until ghostscript runs on an upstream snapshot of lcms2. We won't take ghostscript's forkish of lcms2 as our lcms2 package. ** Changed in: lcms2 (Ubuntu) Status: Triaged = Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1126427 Title: LCMS2 needs multi-threading fixes to work with the new Ghostscript 9.07 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lcms2/+bug/1126427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1126427] Re: LCMS2 needs multi-threading fixes to work with the new Ghostscript 9.07
Thank you very much for applying the changes, unfortunately, something went wrong in your application of the patch. I have built Ghostscript 9.07 against the patched library and it segfaults on most PDF files.

[Bug 1126427] Re: LCMS2 needs multi-threading fixes to work with the new Ghostscript 9.07
I succeeded to fix the patch for lcms2, comparing the lcms2 which comes with upstream Ghostscript and the upstream source tarball of the Ubuntu lcms2 package. The debdiff with the resulting patch is attached. With this version Ghostscript 9.07 is absolutely stable (tested ~20 PDF files).

[Bug 1126427] Re: LCMS2 needs multi-threading fixes to work with the new Ghostscript 9.07
The Ghostscript developers did also some optimizations of LCMS2 for Ghostscript. These optimizations were also made available for upstream, see: https://github.com/robinwatts/Little-CMS/commits/artifex The attached patch contains the fixes from above and the optimizations. So you can choose whether you apply only the fixes (first patch) or the fixes and the optimizations (this patch) to the Ubuntu package of LCMS2. ** Patch added: threading-fixes-for-ghostscript-with-optimizations.patch https://bugs.launchpad.net/ubuntu/+source/lcms2/+bug/1126427/+attachment/3530400/+files/threading-fixes-for-ghostscript-with-optimizations.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1126427 Title: LCMS2 needs multi-threading fixes to work with the new Ghostscript 9.07 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lcms2/+bug/1126427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
