Re: [Inkscape-devel] Memory Problems

I tried doing what you suggested. I went though 26 slides, since it seemed to be enough to get an indication of the behavior. (Just to clarify - I opened the next one (from within the current one), then closed the current one - if I had closed the current one first, the memory would be cleared) The memory used seems to be roughly equivalent between inkscape and inkview, although inkview does use less. Either way though, the memory keeps going up as I go through more slides. I attached three files to this email - the result of doing the command: ps aux | grep -e "inkview" >> memory.txt; free -m >> memory.txt for three cases: memory_inkview.txt: after I clicked the right arrow to advance each slide, I ran the command. memory_one_per_time.txt: I did what you suggested, and opened each file in inkscape, then closed the old one, running the command for each new file. memory_all_open.txt: I opened each file in inkscape, but didn't close the previous file, so by the end, I had 26 files open at once. I ran the command after each file was opened. Thanks for your help, Rich.

new debugging aid
by MenTaLguY 05 May '05

05 May '05

I've introduced a logging facility; the goodies are in the Inkscape::Debug namespace. Set the INKSCAPE_DEBUG_LOG environment variable to a filename, and Inkscape will write a structured XML outline of its activities there. You can take advantage of this when debugging your own code. For example, if you want to highlight the changes that happen during a function, you add this to the top: Debug::EventTracker<Debug::SimpleEvent> tracker("my-func"); (if the function isn't inside the ::Inkscape namespace, you'll need to fully-qualify the type names) After you recompile, any (logged) events that happen during a call to your function will appear grouped under a <my-func> tag in the log. For example: <my-func> <set-attribute node="element(0x8956a218)=svg:g(#g123)" name="foo" value="bar"/> </my-func> (How it works: the <my-func> tag is written from the EventTracker's constructor, and </my-func> is written from its destructor when it goes out of scope.) If you want to log fancier stuff (e.g. taking advantage of attributes) you'll currently need to write your own subclass of Debug::Event and use that instead of Debug::SimpleEvent. Note that EventTracker will not create a Debug::Event object unless the log is turned on, so you don't pay a performance penalty when you're not using it. See src/xml/simple-node.cpp for some examples (which are sadly probably more complicated than they need to be). -mental

[Fwd: SourceForge.net: Notice to project admin of upcoming project web and statistics changes]
by MenTaLguY 05 May '05

05 May '05

-----Forwarded Message----- From: SourceForge.net Team <noreply@...34...> To: mental@...3... Subject: SourceForge.net: Notice to project admin of upcoming project web and statistics changes Date: Thu, 05 May 2005 12:33:34 -0700 Greetings, This message provides an overview of upcoming changes to the SourceForge.net statistics system and the project web service. You are receiving this message because you are presently listed as an administrator of a project hosted on SourceForge.net, and we deem these changes to be important enough to notify all active project administrators. This is a one-time mailing. See the BOTTOM of this message if you are no longer active on SourceForge.net. A. Project Web Service A significant amount of recent work has gone in to improvements to the scalability and security of the project web service. On 2005-05-23, we will be remounting project group directories read-only on the project web servers (they will remain read-write from the shell server). This may impact existing project web applications. All projects are encouraged to review our new documentation and modify their application configuration as needed. http://sf.net/docs/E07/ This change is being made in accordance with the previous site mailings announcing project web changes, referencing the Master RFE at: http://sf.net/tracker/index.php? func=detail&aid=1109940&group_id=1&atid=350001 Additional details regarding the project web service, limitations, and the best ways to manage project content under this service, may be found in the recently-released Project Web, Shell and DB service guide, at: http://sf.net/docs/E07/ B. Statistics B0. Introduction and timeline The SourceForge.net team has been working for nearly a year to complete a total replacement of the existing project and site statistics infrastructure. It is our pleasure to announce that this work is reaching completion, and to provide some details to manage your expectations about the launch of the new statistics service. We expect to announce no later than 2005-05-16 the timeline for deployment of the new statistics system. This announcement will be made via the the Site Status page. https://sourceforge.net/docs/A04/ B1. Scalability, performance, outage reduction: The statistics system has been completely re-engineered as to cope with the growing size of the site user base, and of our service offering. With the launch of this new system, there are bound to be a few bugs (though we've performed extensive QA review of these changes and systems to try to reduce the problem set). We ask that all statistics related bugs found post-launch be submitted to us for review (even if they seem minor, or duplicative to those previously reported) at: https://sourceforge.net/tracker/?func=add&group_id=1&atid=200001 B2. Project ranking formula change: One of the changes which is expected to most impact projects is the alteration of the project ranking formula. This change may significantly alter the top project rankings, giving greater ranking to those projects who are not just frequently-downloaded, but also those projects who are active in using the Tracker and communication tools provided by the site. The OLD project ranking formula was: log (3 * # of forum posts for that week) + log (4 * # of tasks ftw) + log (3 * # bugs ftw) + log (10 * patches ftw) + log (5 * tracker items ftw) + log (# commits to CVS ftw) + log (5 * # file releases ftw) + log (.3 * # downloads ftw) -- This has been detailed in our older Site Documentation as seen at: https://sourceforge.net/docman/display_doc.php?docid=14040&group_id=1 With the new statistics system launch, we expect to provide new Site Documentation. The new documentation will include the final form of the NEW ranking formula. The new ranking formula splits project rankings in to three components: traffic, development, and communication. We expect the new ranking formulas to be: Traffic: ( (log(last 7 days download total) / log(highest project download total)) +(log(last 7 days logo hits) / log(highest project logo hits)) +(log(last 7 days site hits) / log(highest project site hits)) ) / 3 Development: ( (log(last 7 days cvs commit total) / log(highest project total)) +( (100-last file release age (days, max 100)) / 100 ) +( (100-last admin login age (days, max 100)) / 100 ) ) / 3 Communication: ( (log(last 7 days tracker artifact #) / log(highest project total)) +(log(last 7 days ML post count) / log(highest project total)) +(log(last 7 days forum post count) / log(highest project total)) ) / 3 Total: total = traffic + development + communication All of the 'highest' figures reference totals for the last 7 days. In the case of 'log(last 7 day site hits for this project) / log(last 7 day site hits for the project with the most site hits)', for example: If Project X is the busiest site this week with 10,000,000 hits and Project Y has had 200,000 hits then it's Y score = log(200,000) / log(10,000,000) We believe that this ranking method gives us the capability to better evaluate project activity, and to more directly reflect total product activity in how projects receive site exposure via the top site rankings. B3. Post-launch components and your feedback After the initial launch of the new statistics system, we will be working to complete the components to track CVS activity and mailing list activity. These components have not yet been completed, and are expected to launch at a later date (to be announced after the initial shake-out of the new system). Additional statistics system enhancements are also under consideration for implementation after the initial launch. Once the initial launch has occurred and you have had opportunity to examine the new facilities, we encourage you to contact us (via our Feature Request Tracker) regarding enhancements you would like to see. https://sourceforge.net/tracker/?func=add&group_id=1&atid=350001 B4. Documentation The release of new documentation (within the SourceForge.net Site Documentation collection) is expected to coincide with the new statistics system launch. Links will be provided to the new documentation from our Site Status page and Enhancements page. An itemized overview of the major changes carried by the new statistics system will be listed on the Enhancements page at time of launch. https://sourceforge.net/docs/A03/ https://sourceforge.net/docs/A04/ B5. Existing statistics data Existing statistics data (from the old statistics system) has been carried forward to the new statistics system. For the time period that the new system has actively been pulling real-time data from our servers, we plan to recompute project ranking data. All other project statistics should match those found in the old system. C. Conclusion Regarding Project Web: As documented here, project group directories will be remounted read-only on 2005-05-23. All writable files will need to be placed in the /tmp/persistent directory structure (create a subdirectory for your project). Additional details may be found in section A, above. Regarding Statistics: We are considering the completion of our new statistics system to be very high priority, and are taking only the time we need to ensure a highly consistent and functional system has been implemented. We expect to announce no later than 2005-05-16 the timeline for deployment of the new statistics system. Additional details may be found in section B, above. We hope that your team will find added benefit through our efforts, and encourage your continued support and feedback. Thank you, SourceForge.net staff http://sf.net/tracker/?func=add&group_id=1&atid=200001 --------------------------------------------------------- When the SF.net team sends out a site-wide email, we sometimes see replies that look like this: "Hey! I didn't ask to be on this list! You spammer. I hate you! I hate your dog! (insert other colorful phrases here)." The truth is, we've only sent this mailing to registered project administrators on SourceForge.net. If you do not believe you should have received this mailing, use the link above to submit a Support Request and we'll be glad to assist you. .

Memory Problems
by Richard Kowalczyk 05 May '05

05 May '05

I have a presentation of about 50 slides. When I go through the slides with inkview, it quickly eats up all of my memory (512 mb). I dont know a proper way to describe the memory usage, so I will list some info: Memory only goes up when I change slides. If it sit on the same slide, it is fine. If I just go back and forth between two slides, memory will increase each time I go back and forth, until it eventually levels off. Then I can flip back and forth between those two slides without any increase in memory. When I flip to more slides, memory goes up again. I can go through the whole presentation once, and memory will go to a certain value. Going backwards, or going to the start and showing slides again will continue to increase the memory. Eventually, after playing with the slides for about 15 minutes, inkview will crash, and print "Killed" to the console. I am basing my statements about memory on "ps aux" and "free -m". I will be glad to do anything else that anyone thinks will help explain the memory usage. I will be glad to send the presentation to anyone also. It is about 7 mb uncompressed. Thanks, Rich. -- Richard Kowalczyk <richk@...805...>

layer add hang
by MenTaLguY 05 May '05

05 May '05

The layer addition hang appears to be due to the failure of the "change handlers should only be called for events that happen after they are registered" invariant I mentioned. Basically what is happening is that on a layer switch, the layer selectors each register a new handler (after unregistering the old one), but those handlers immediately get called for the event that has already happened, repeating the process and creating an infinite treadmill. The obvious fix is to defer addition of new change handlers to the list until after all the existing handlers have been called. Of course that is not a sufficient guarantee for the recursive case, but hopefully there are no recursive changes involved here. -mental

Looking for autopackage maintainers (again)
by Mike Hearn 05 May '05

05 May '05

Hi, As the latest nightly build break shows, I'm not plugged into Inkscape development enough to keep the specfiles accurate. In particular the packages broke because I was still trying to copy the lib directory which no longer exists. Maintaining these specfiles is trivial. If somebody wanted to take them over I'd be happy to help and also happy to continue running the nightly build system. If anybody is interested please let me know. thanks -mike

Updated spanish translation
by Lucas Vieites 03 May '05

03 May '05

Hi, I'm attaching an updated spanish translation. It's not complete, but I'll finish it once it has all the new changes in it. I'm having trouble with a word: Unclump. The complete string is: "Unclump objects: try to equalize edge-to-edge distances" and several others. Can someone explain this to me or even better, send a screenshot before unclumping and after unclumping so I can see the effect. Thanks -- Lucas Vieites Fariña Dept.

Inkscape on DeviantArt
by Joshua A. Andler 02 May '05

02 May '05

This is a follow-up to a post made back in January regarding Inkscape's presence on DeviantArt (DA)... Over time, more and more artwork is being submitted to DA that was created using Inkscape. Since we had initially started the "Inkscape" group/account on DA, we quickly realized that there are two groups of people that have exclusive needs to be met. 1) The DA Inkscape artists needed a hub to share work, talk inkscape, have friendly competitions, etc. & 2) The developers and new users of Inkscape need a place to view/show a gallery of quality images made in Inkscape by the DA community. The problem with having one account is that it DA has policies such as restricting the use of favorites from members of a group, which given the mutually restrictive needs (due to their policies), we needed a separation of interests. So... onto the announcement. http://inkscapers.deviantart.com/ is now *the* place for all DA Artists that are Inkscapers to gather for all of the fun. We currently are in need of an Avatar, DevID, and website button... which is where the first contest comes into play... all the details can be found at http://inkscapers.deviantart.com/journal/4986039/. http://inkscape.deviantart.com/ is now for official use by the Inkscape project for a showcase of work from the community as well as for official announcements and such. Feel free to drop by there to see art done by fellow inkscapers in the favorites (http://inkscape.deviantart.com/favourites/). If you have previously watched the "inkscape" account, there's no need to stop watching as you'll get announcements about new releases through it. But, you will definitely want to watch "inkscapers" (http://inkscapers.deviantart.com/) to become a part of the DA Inkscape community and to join in on the fun. Happy Inkscaping and Draw Freely! -Josh/ScislaC-
