gc-awareness
by MenTaLguY 13 Aug '04

13 Aug '04

I've just reworked SPRepr to derive from Inkscape::Refcounted, so it is garbage-collector-aware (I've already done this with NRObject). What I mean by "gc-aware" is that it is safe to put pointers to garbage-collected objects in them, and that they are managed by the garbage collector. Normally gc-aware objects should derive from Inkscape::GC::Object or Inkscape::GC::FinalizedObject. GC::Object is the most lightweight of the base classes; it has no overhead, but destructors will not be run when it is collected (not a problem if there are no nontrivial destructors). GC::FinalizedObject (deriving from GC::Object) runs its destructors before it is collected, but there is additional overhead for tracking the destructors and a C++ vtable. Inkscape::Refcounted (which derives from FinalizedObject) is the heaviest of the "gc-aware" base classes, as it adds the overhead of an "Anchor" pointer and a refcount. The refcount is initialized to 1. It's also special among managed classes in that it allows you to safely keep references to Inkscape::Refcounted objects in non-gc-aware classes; all you need to do treat them like normal refcounted objects; increment their refcount with Inkscape::Refcounted::claim(), and decrement it with Inkscape::Refcounted::release(). As a result, an Inkscape::Refcounted will never be collected out from under you so long as its refcount is nonzero. The intent is that Inkscape::Refcounted will provide an interface between non-gc-aware code (e.g. classes derived from GObject or gtkmm's Glib::Object), and lighter-weight gc-aware objects. (it's safe to store pointers to gc-managed objects in automatic, global or static variables, as well as function parameters, so this is only a concern for storing pointers in dynamically-allocated objects) By the way, we can't simply make glib use the boehm allocator, since glib is used to allocate pixmaps, and RGBA pixmaps look like huge arrays of pointers. Maybe we could get away with it, but I think that'd be pushing our luck with a conservative collector. -mental

textFlow Example
by Jon Phillips 13 Aug '04

13 Aug '04

I made a full page letter overview of inkscape using the new textFlow features. I wrote it in a text editor. Once a UI is done for this feature, the usefulness of inkscape is going to scale incredibly!!! http://www.inkscape.org/doc/index.php I also split the documentation into user and developer on the website and updated the news.

breakage!
by bulia byak 13 Aug '04

13 Aug '04

Current CVS is unusable. 1. Start, press ctrl+n. Tools icons partially disappear on the new window. Open fill&stroke. At first only the stroke color tab icon is lost. Close the dialog, open again. Now all icons disappear. 2. Draw anything with the bezier tool. You get: ** (inkscape:19152): CRITICAL **: file sp-item.cpp: line 774 (NR::Matrix i2anc_affine(const SPObject*, const SPObject*)): assertion `object != NULL && ancestor != NULL' failed ** (inkscape:19152): CRITICAL **: file sp-item.cpp: line 774 (NR::Matrix i2anc_affine(const SPObject*, const SPObject*)): assertion `object != NULL && ancestor != NULL' failed Please fix ASAP. P.S. Please try to better test things before committing.

session id bug squashed
by Jon Phillips 12 Aug '04

12 Aug '04

FYI (cuz this is not on the roadmap): I fixed the website Session ID bug on both inkscape and open clip art library. That should give a bit of boost to web traffic and less errors when moving between wiki and web pages.

I've been dealing with them in my 'REAL' work. They just suck most of the time but they can also be your best friends (When crosscompiling).. I don't see necesery to move away from autotools but inkscape build system should be cleaned a much. Example those makefile_insert stuff should gogo and that autogenerate depencies just make it worse.. There should be one person whose taking care that build is working (buildmanager?). I don't know if there such person in inkscape project. If someone wants to investigate alternatives there is SCONS (http://www.scons.org/) I haven't used it but seen big projects to get simple buildsystems with it (example http://www.blender.org).. it should work on MacOSX and Windoze also.

Theming
by Karl Ove Hufthammer 11 Aug '04

11 Aug '04

Is there any work currently being done on making Inkscape themeable like other Gnome/GTK apps? There's mention of this on "http://inkscape.org/cgi-bin/wiki.pl?GtkMMification": As part of doing the migration to gtkmm you should try and get icon theming working properly. While not directly related to the port I think fixing it when redoing the GUI anyway is a good time. There are a couple of things to keep in mind. For icon shared by Inkscape with all GTK+ and GNOME apps (file new, file open) etc. you should just use the standard icons. Look at gedit for sample code of how it is done. For icons that Inkscape shares with other drawing apps like The Gimp you should adopt the stock icons defined by The Gimp (floodfill is a good example here). For the remaining icons you would need to define them yourself, good thing here would be to make sure Sodipodi could use the same stock icons definitions so that when someone icon themes Sodipodi or Inkscape both apps picks up the correct icons. -- Uraeus -- Karl Ove Hufthammer

Startup?
by Bob Jamison 11 Aug '04

11 Aug '04

This morning (Monday) I have been having trouble running CVS inkscape. Even after doing clean checkout/builds, the resulting inkscape does not show a GUI, even after 5 mins. Has someone modified the startup? Bob

Server downtime
by Bob Jamison 10 Aug '04

10 Aug '04

My net admin just told me that they will be taking down troi.titan-aeu.com, in order to move it to a new building. It will be down for some time; maybe a few hours, maybe a few days. So if you want Win32 nightlies, you will need to go to Daniel's site in the meantime. Bob (ishmal)

Well, 6Mb is not what I would call typical. Half an hour sounds like a lot. How long does it take to actually open that file? On a 450MHz Windows machine that I tested, it works quite acceptably for SVG files of average size and complexity (up to several hundred Kbytes). I'm not saying using stored previews is not an option; I'm just saying that the current code works quite acceptably for the average user, so implementing an alternative is not a priority (though of course I would not object if someone develops and commits it). > I'm just speaking about the preview area. It has the "Preview" title, Which is rather redundant IMHO, especially being so button-looking - is it actually clickable? what does it do? why does it have a keyboard accelerator? What we actually need is a checkbox or an expander triangle to turn the preview on or off. > some space around the image Which is confusing - I want the preview to match the actual look, without having to guess if this margin an actual part of the file or not > shows the file size Which is good, but properly belongs in the file list as a separate sort-able column, not in the preview (by the way, Bob, can we add the filesize column to the list?) > and displays a folder > icon, if you are an a folder an not on an image. It might make sense to borrow that one.
