On the use of C++ exception handling
by Rodrigo B Almeida 12 Aug '14

12 Aug '14

Dear all, I've been investigating the use of C++ exception handling constructs in open-source C++ projects (including inkscape). Currently, I am conducting a survey on this subject and I would really appreciate if you could contribute to this research by answering a few questions. The survey is available on-line: https://pt.surveymonkey.com/s/exceptionHandling All the best, Rodrigo.

Status of 0.91 and a vote on the bug hunt!
by Bryce Harrington 12 Aug '14

12 Aug '14

With us now at the halfway milestone for the bug hunt, this is a good point to reflect on how the release is doing, and I'd like to hear your thoughts. In past releases we set a goal of 500 points worth of bugs; today we've hit 778, which is pretty amazing! We set a higher goal than usual due to the length of time since our last release, knowing that we probably needed to give more time than usual for QA and to get things stabilized. How do you feel we're doing? Do you feel Inkscape is solid enough that we could call it good on the bug hunt and proceed with the next stage of the release (perhaps with a select list of must-fix blocker bugs)? Or do you think the bug hunt is helping stimulate a lot of good bug work that we should continue? Or something else entirely? Give me your vote publically or privately and I'll make the appropriate course changes to get the release moving ahead. Bryce

0.48.5 and libsigc++-2.3.2
by Ken Moffat 08 Aug '14

08 Aug '14

Hi, I do some things at beyond linuxfromscratch ( http://www.linuxfromscratch.org/blfs/view/svn/ ) and have recently started including 0.48.5 in my own builds. We have been using libsigc++-2.3.1 for some time (I guess that whoever added it did not realis it was a development version), so we went with 2.3.2. Unfortunately, that breaks inkscape-0.48.5. The specific change was announced at https://mail.gnome.org/archives/libsigc-list/2014-August/msg00000.html where it mentioned runtime errors for users who added their own visit_each overload. In fact, for 0.48.5 it broke the build, and the relevant message appeared to be : /usr/include/sigc++-2.0/sigc++/visit_each.h:169:64: error: cannot convert ‘const sigc::adaptor_functor<sigc::bound_mem_functor0<void, SPDesktop> >’ to ‘int’ in initialization /usr/include/sigc++-2.0/sigc++/visit_each.h:169:29: warning: unused variable ‘do_visit_each’ [-Wunused-variable] { sigc::visitor<T_functor>::do_visit_each(_A_action, _A_functor); } ^ CXX device-manager.o Makefile:5958: recipe for target 'desktop.o' failed make[2]: *** [desktop.o] Error 1 Dropping back to 2.3.1 fixed it. One of my colleagues created a patch to locally revert that particular change in libsigc++ which also fixed the build. My first question [ at last! ] is: Do you care about people who build 0.48 with libsigc++-2.3-series ? If you do, any ideas how to fix this ? Thanks. ĸen -- Nanny Ogg usually went to bed early.

Cairo rendering of SVG arcs
by Liam White 08 Aug '14

08 Aug '14

Hi I found out that for certain SVG files, rendering can likely be sped up a lot by directly rendering SVG elliptical arcs with Cairo instead of converting them to cubic Beziers and rendering those. I expanded our current code in experimental to do that, and it... almost works. I'm not quite sure what I'm doing wrong at the moment, hopefully someone can help me with that! The code works well for perfect circles. It does not work well for ellipses, but doesn't seem to have any issues with rotation of ellipses. Any optimization tips would be appreciated, as this code is called extremely often. #line 558 "src/display/cairo-utils.cpp" else if (Geom::EllipticalArc const *a = dynamic_cast<Geom::EllipticalArc const*>(&c)) { Geom::EllipticalArc* tx = static_cast<Geom::EllipticalArc *>(a->transformed(trans)); Geom::Affine xform = tx->unitCircleTransform(); // Normalize the ellipse into a circle Geom::EllipticalArc * ax = static_cast<Geom::EllipticalArc *>(tx->transformed(xform)); bool sweep = /*ax->sweep(), large_arc = */ax->largeArc(); Geom::Point ce = ax->center(); Geom::Point ang(ax->initialAngle().radians(), ax->finalAngle().radians()); // Apply the transformation to the current context cairo_save(cr); cairo_matrix_t cr_trans; xform = xform.inverse() * trans; cairo_matrix_init(&cr_trans, xform[0], xform[1], xform[2], xform[3], xform[4], xform[5]); cairo_transform(cr, &cr_trans); if (!optimize_stroke || tx->boundsFast().intersects(view)) { // Draw the circle if (sweep) { cairo_arc(cr, ce[X], ce[Y], ax->ray(X), ang[0], ang[1]); } else { cairo_arc_negative(cr, ce[X], ce[Y], ax->ray(X), ang[0], ang[1]); } } else { cairo_move_to(cr, ax->finalPoint()[X], ax->finalPoint()[Y]); } cairo_restore(cr); delete tx; delete ax; return; } http://cairographics.org/manual/cairo-Paths.html#cairo-arc

Re: [Inkscape-devel] Cairo rendering of SVG arcs
by Liam White 07 Aug '14

Thanks Krzysz! That fixed it and now CLI rendering of a file with a tremendous amount of arcs seems to be a bit faster: Unpatched trunk: 0m9.161s Patched trunk: 0m7.577s However, something else I might have to investigate is that with my sample file, experimental seems to have suffered a serious performance regression: Unpatched experimental: 0m20.539s Patched experimental: 0m19.482s

Recent change to SVG parsing
by Krzysztof Kosiński 07 Aug '14

07 Aug '14

Hello Recently there was a change to SVG parsing in lib2geom, so that arc segments that end less that EPSILON (1e-5) units from where they begin are ignored. However, this threshold is completely arbitrary and there is no way to change it. I think this should either be changed to strict equality, or there should be a way to set this threshold (in Inkscape, it should be dependent on the numeric precision of XML output). Regards, Krzysztof
