Threading problem in extension system
by Johan Engelen 02 Jul '14

02 Jul '14

Hi all, There is a threading problem with the extension system. It results in a crash when saving a document and quitting while the save is happening. Have a look here: https://bugs.launchpad.net/inkscape/+bug/967416 I don't know enough about glib's threading to fix this bug. I do not fully understand where the execution flow is going after the fork (/src/extension/implementation/script.cpp, line 1017, _main_loop->run();), nor where the fork is terminated. I hope someone who knows more about this can have a look. I'm afraid it may lead to pretty weird bugs when running time consuming extensions and doing stuff meanwhile. (gdb reports illegal mem accesses when doing stuff while an extension is running, for example). Is this asynchronous extension execution so important, or can we disable it for now to improve stability? regards, Johan

Stable PPA not built correctly
by Liam White 29 Jun '14

29 Jun '14

Hi, I've noticed a problem with the stable PPA. It seems to contain incorrectly built packages. The resulting .deb files from the build are approximately 12 KiB. They contain no binary data. The build logs leave a clue to the problem: chroot-autobuild/build/buildd/inkscape_0.48.5+31~ubuntu14.10.1_amd64.deb: dpkg-deb: file `chroot-autobuild/build/buildd/inkscape_0.48.5+31~ubuntu14.0.1_amd64.deb' contains ununderstood data member data.tar.xz , giving up You can see more details here <https://code.launchpad.net/~inkscape.dev/+archive/stable/+build/6118562>.

Re: [Inkscape-devel] GSOC status report - Better support for SVG paints

I've noticed that symbols, patterns and swatches are very similar in the way they can be stored, rendered and presented to the user. They are all fragments of SVG documents, usually stored in /shared directory. When I finish implementing model for strong paints I'll see if it's usable for symbols. It seems to me much of the code can be shared. In addition to symbols dialog, size of the tile and fitting into tile will be controlled in swatches dialog. TileView widget supports it. I have to choose what kind of UI to use for setting the size. Currently the symbols dialog uses buttons at the bottom, while existing swatches dialog provides menu with options to control the look. In addition to this, in my proposal [1] I sketched a dialog for TileView configuration, but now I see it using it would mean a lot of clicking.

Review: C++ for Inkscape Core
by Martin Owens 26 Jun '14

26 Jun '14

Dear Developers, I've been asked to review a large patch by Liam which is an attempt to C ++ify the core of inkscape, removing inkscape-private.h and making objects. I'm going through the code as requested, but I feel this patch will need more than me to give it the OK. Can I request some of the bright peers working on C++ification to give the patch their blessings too? Merge Request: https://code.launchpad.net/~inkscapebrony/inkscape/inkscape-cppify/+merge/2… Best Regards, Martin Owens

Undefined but declared hash<> template causing C++11 trouble
by Johan Engelen 25 Jun '14

25 Jun '14

Hi Krzysz, The following lines in ui/tool/node.h are causing trouble with gcc 4.9 C++11: #if HAVE_TR1_UNORDERED_SET namespace std { namespace tr1 { template <typename N> struct hash< Inkscape::UI::NodeIterator<N> >; } } #endif Is it OK to remove those? If I comment them out, all seems to work fine. I cannot find the specialization definition anywhere, so seems only a fwd decl? regards, Johan

inkscape-0.91pre1 source tarball
by Bryce Harrington 24 Jun '14

24 Jun '14

Download it at: https://sourceforge.net/projects/inkscape/files/inkscape/0.91pre1/ Tagged in trunk as: INKSCAPE_0_91_PRE1 It would be helpful if packagers could generate binary platform packages from this tarball. If you spot packaging problems (like version numbers that didn't get updated, or missing files needed for builds), please raise these problems with me ASAP. Bryce

Inkscape 0.48.5 - tarballs posted
by Krzysztof Kosiński 23 Jun '14

23 Jun '14

Hello The last bug was fixed in the Windows devlibs, so I tagged the 0.48.5 release and posted the tarballs to Launchpad. They should be available for download now. https://launchpad.net/inkscape/0.48.x/0.48.5 As usual, the announcement should wait until packages for major platforms are ready. (This is the first time I'm doing a release for a major project, so I hope I didn't make any big blunders.) Regards, Krzysztof

LPE on clip/mask - Bug 1241902
by Johan Engelen 23 Jun '14

23 Jun '14

Hi all, Recently, a fix to Bug 1241902 was committed. But... I have second thoughts now. Do we really want to apply LPEs to clip and masks? Now, clips on a path with, say, LPE Sketch, works very weird. I now think that we really don't want to apply LPEs on clips/masks. cheers, Johan
