ANY REPLY MADE TO THIS MESSAGE WILL NOT BE COLLECTED AND INSERTED IN THE BUG DATABASE. http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10941 Memory leaks when using dynamic images Summary: Memory leaks when using dynamic images Product: Fop Version: all Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Major Priority: Other Component: pdf renderer AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Hi, I have discovered some memory leaks when creating dynamic reports with dynamic (gif) image files. The problem is that image files seem to be cached and not released anymore, even when removing the fop driver object or calling the driver.reset() method. Since we are making dynamic reports and all charts in it are stored with unique filenames (to prevent concurrency problems between users), every created report keeps about 40 kb of memory in memory. After a few days, this results in tomcat to crash because the system gets out of memory (with heap size of 256 MB). When I always use the same GIF filenames and start a one user test repeatingly making reports for one user, one after the other, there is no memory leak. This means that the memory leak is caused by caching the image files and never releasing them. When the same filenames are reused over and over again, the cached image files are overwritten for every new report. After investigating the FOP source code (0.20.4) I discovered at least one problem in the FopImageFactory.java class: There is a private static Hashtable m_urlMap that caches all image URLs but never releases these URLs. Since it is a static map, the URLs are not even released after removing the fop objects from memory. When I solved this problem on my PC (by clearing the m_urlMap after calling the Driver.Reset method) there is still memory leak of about 30 kb left. Does anyone know about this problem and is there a possible work around (except from reusing the filenames)?

font state and associates
Hi All, Has anyone looked at the font state stuff. It appears we could make some changes to improve the way fonts are handled. - handle font information easily - handle font lists, resolving on a char basis - reduce number of FontState objects if information is the same (or similar?) - allow for serialization as part of area tree Do we need the FontInfo and FontMetric inside the FontState? Can we have a list of all font states so that it can be retrieved when needed for a particular layout of area? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Re: font state and associates
Hi Keiron Not enough to be of any help right now. But reading this the Flyweight pattern from the Design Patterns book comes to my mind immediately. The list of all font states is the consequence of this pattern which could be very helpful for the renderers. The PS renderer still writes a list of all registered (instead of used) fonts at the beginning so they are available when necessary. You can't just register objects into the stream when encountered like in PDF. Of course, the list grows over time during layout while the renderer should already start writing out pages. But that's another problem... Sorry, if this a bit meager but on the other side In two weeks I'll be starting my well-earned 7 weeks long holidays after really intensive 10 months. I'll be away during two weeks in August but I'll have 5 weeks from which I'd like to spend at least a full week to help with the redesign without having customers in my neck (read: I want to have some fun). Let me know if there's a particular area I could help out. I was thinking about the following areas: Avalon, Configuration, API, renderers. But I'd be glad to help in other areas if I can. While I'm at it, I'd like to apologize for my lack of participation during the last weeks (especially with the API stuff). Too many things buzzing around my head...
