Information Request
by stephen.lohning＠oxnee.com 01 Jul '19

01 Jul '19

I would like to develop an extension to start with in python 3+ on windows, and I am not very sure of where to start. I just read the extension requirements which said the extensions need python 2. It also said that it was a little out of date. If need be I would be willing to modify it for python 3. I have programmed C/ C++ and half a dozen other languages over the years, my main problem is that I don't have a compiler for Window. I do have a Centos 7 machine which I could set up a dev environment, but my use is on a windows system. My aim is to do away with my need for MS Visio which I don't like very much and do my drawing parametrically. Regards Stephen

Mailing list neither enabled or disabled
by Terry Brown 21 Jun '19

21 Jun '19

Perhaps this happened to a lot of people and maybe it's been discussed, but I dropped off inkscape-devel and inkscape-users. I think I signed up for the new lists as soon as I saw the announcement, but checking my settings just now the radio buttons Delivery status: Enabled [ ] Disabled [ ] were both off, the mailing list was neither enabled or disabled. Wonder if it happened to others. Fixed from my point of view now. Cheers -Terry

development
by Andrew Kurn 19 Jun '19

I'd like to ask your advice on how to set up a development environment for Inks. Can I do it on an old 32-bit machine? Can I do it on a Raspberry Pi? Can I do it with just gcc and make? If there is someone who is willing to answer questions of this type, perhaps you would like to mentor me. Andrew

TV coverage on LGM
by Maren Hachmann 11 Jun '19

11 Jun '19

Hi everyone, I just got a reply from Agnès from K8, about the press coverage. Starting at ~ 24:00 of https://www.sr-mediathek.de/index.php?seite=7&id=74463 , there's a TV report about the mapathon before LGM, which ends with pictures of some charitable open source graphics software developers (aka Mc, @jnweiger and @mgmax ) around minute 27. She wrote that a team from the French TV was there, too, but that their report isn't available yet. When it will be released, that will be at https://www.tv8.fr/VOD/Grenzenlos/09-05-2019-grenzenlos-TME4BFMq1i.html. Regards Maren ------------ > > Hallo Maren, > > hier den Link zum SR-Bericht: > https://www.sr-mediathek.de/index.php?seite=7&id=74463 > > Aus Frankreich war der lokale Sender TV8 Moselle Est da aber der > Bericht ist noch nicht online.

upcoming opening of new Inkscape forum
by brynn 09 Jun '19

09 Jun '19

Hi Friends, The Inkscape website will be opening a new forum in August 2019. The primary purpose of the forum will be providing support for Inkscape, but it will serve the whole project and community, in whatever way it can. It will function in much the same way that InkscapeForum.com (http://www.inkscapeforum.com/index.php) and Inkscape Community's forum (https://forum.inkscapecommunity.com/index.php?action=forum) currently do. Concurrently to opening the new forum, Inkscape Community's forum will essentially close. All of its forum traffic will be diverted to the new forum (although its tutorials and other resources will remain available). Since the Inkscape project has lost contact with the owner of InkscapeForum.com we assume it will remain open. Please make plans to change your forum bookmarks, and to visit the new forum in August. If you're not already registered on the Inkscape website, you will need to register. Once you're logged in to the website, you're also logged in to the forum. We will be thrilled to welcome you, and to provide the same quality of support you're accustomed to! Here is the link to the new forum. Although please note that posting will not be allowed until August. But you can look around and see everything about how it works, except for posting a message. https://inkscape.org/forums/ If you have any questions, please feel free to ask. All best, brynn

Board meeting Friday Jun 7th at 10am Pacific
by Bryce Harrington 08 Jun '19

08 Jun '19

Our monthly board meeting is scheduled for Friday, Jun 7th, at 10am Pacific in #inkscape-devel. All members are welcome. http://wiki.inkscape.org/wiki/index.php/Board_Meetings Agenda: ------- * CoC: escalation point person needed * Hackfest debrief [http://libregraphicsmeeting.org/2019/ LGM 2019] * Infrastructure ** mailing list migration off SourceForge ** Wiki migration off OSUOSL * GSoC * Other Business ** CoC Escalation Point *** Need someone to handle escalated complaints re CoC, since Krzysztof Kosiński has resigned. Hopefully someone with training or experience with conflict resolution or mediation. Not much time needed, probably would never happen, but need to be ready just in case. Currently it's vacant. ** Forums: Should a job postings area be included? *** Discuss the possibility of having something like a jobs board on the new forum. Something similar to https://forum.inkscapecommunity.com/index.php?board=12.0 Would need strict rules to prevent misuse, spam, liability, etc. Action Items from last meeting: ------------------------------- == Bug Migration == ♢ ACTION: (Blocked) Check with SFC if amounts of $100 / $50 / $25 for 1st, 2nd, 3rd is within IRS limits [bryce] ♢ ACTION: (Blocked) Hold referendum on top game prizes after confirmed by SFC [bryce] == Inkscape 1.0 beta == ♢ ACTION: Check in with people doing test case conversion [Tav] ♢ ACTION: ping jimmac/barbara about the symbolic icons for adding the theme to Inkscape [scislac] ♢ ACTION: Plan video for Inkscape 1.0 release [crogers] ♢ ACTION: Brainstorm plans for 1.0beta / 1.0 commemorative merch [crogers, tedg] === Sponsorship Management === ♢ ACTION: Find out about the new event insurance from #conservancy [tedg] Transcripts of previous meetings: --------------------------------- http://alpha.inkscape.org/board/meetings/transcripts/ Bryce

Profiling Inkscape startup performance
by octycs 08 Jun '19

08 Jun '19

Hello everyone, While I'm an Inkscape user for some years now, I'm fairly new to it from a developer point of view. In terms of performance, I've been recently doing some analysis with the help of cpu profiling tools. My aim in this mail is to present some of the things I noticed and maybe some ideas how to improve them. The tools I've been using are the gperftools and more recently the linux performance tool `perf` together with FlameGraphs (Disclaimer: Since I've been using them for the first time I don't have a deep knowledge about them). Both tools can capture the stack at a timed interval, so it is possible to estimate how much time is spent in different functions. These can be visualized for example by a flame graph which I found quite handy. In theses graphs the x-axis shows the stack records alphabetically sorted (not chronologically) and if possible merged. The y-axis shows the call stack. Recording the startup of Inkscape just until before the Window shows up[1] results in the attached results[2]. The original file is an SVG file (Note: This is a large interactive SVG and primarily intended to be opened in a browser[3]). By looking at the result I identified some parts that might be of interest (See annotated PNG file). - A - (100ms): Based on some individual function calls (e.g. get_preferred_width) I assume this is related to the layout calculations. Noteworthy is here that the stack mostly has a depth of up to 80-90 frames. I don't know whether this is usual for gtk, but for me this looks like the calculation of the layout might get very complex. Maybe it is possible in some places to simplify the layout (I'm referring e.g. to [4]). While this part only takes around 100ms in this record, the actual impact could be larger because the recording stops just before the window shows up. However, even after it shows there is a noticeable delay until it gets responsive. - B - (170ms): This part is the setup of the toolboxes at the top. I find interesting here that with the exception of the TextToolbar, each Toolbar only takes 5-10ms to load, but because there are so many of them, they sum up over 100ms (again without the TextToolbar). One idea I'll therefore try to look into in the next time is whether it is possible to lazy-load them, so that the GUI relevant initialization only runs as soon as required (when the tool is used the first time). Since most toolbars initialize in up to 10ms the delay is insignificant when clicking on a tool. - C and D - (65ms / 80ms): These relate to the initialization of the menu resp. the DesktopWidget. I haven't had a much closer look yet, but both take longer than I assumed. There might be some optimizations possible as well (e.g. I noticed SwatchesPanel::_rebuild is called at least twice, each running nearly 20ms). - E - (260ms): The last section is about loading the extensions. I don't know a lot about the extensions system now and the future plans, but I also wouldn't have expected this part to take that much time. - Looking further - The attached recording of the startup here is of course only a part of interesting parts for optimization (And there are also a lot of parts that I cannot identify with certainty). One second aspect I want to look more into is for example the fill and stroke dialog, which takes up to 600ms to load (not part of the attached profiling) because all marker images are expensively loaded and rendered as SPObjects at runtime. And if it is open on startup this time adds up to the delay before the window even shows up. -- All in all I admit that this a rather chaotic collection of maybe or maybe not promising parts for performance optimizations. This surely only touches the surface of possible analysis and improvements, but I wanted to share this early because maybe you have some ideas as well (or there were some things done in the past that I don't know of). If you have any feedback I'd appreciate it a lot. Best regards, octycs [1] I did this by calling exit just before `InkscapeApplication::window_open` returns. [2] The results still have parts that are marked as "[unknown]". I tried solving this by passing "-fno-omit-frame-pointer" (see FlameGraph documentation for more), but this did not have an effect. Though this could also be because cmake automatically re-ran when I started building.
