XPCOM leak tutorial July 24 Submitted by L. David Baron I've written a tutorial on finding leaks of XPCOM objects. It's anannotated list of the steps I took to find a leak (in a roundabout way,for demonstration). I explain how I use the refcount balancer,including the new nsCOMPtr tools, and also quickly describejs_LiveThingToFind. If there are any ways it can be improved, please let me know. -tutorial.html Footprint/Performance July 26 Submitted by Vidur Apparao Parser token and string usageDescription: The parser currently heap allocates small CTokeninstances and keeps them on a recycler list "for performance reasons".The recycler list is currently unbounded in size. Text tokens also usensStrings to store copies of their text data - also heap allocated. Theoverall memory usage shows up high in bloatblame logs. The working setmemory usage also stays pretty high because of the unbounded token recycler.Module owner: harishd@netscape.comTask owner: harishd@netscape.com,scc@netscape.com,vidur@netscape.comStatus: Harish is looking at arena allocating the token objects.Scott is working on a segmented string implementation which can deal withsubstrings that share the underlying buffer for the token strings.Bugs: 46702 "Super global" for JavaScriptDescription: Currently each DocShell has a script context andscript global object associated with it. For each script global object,we initialize the JavaScript core classes and some DOM classes per documentin the shell. This redundancy has both performance and bloat repercussions.The thought is that we might be able to have "super global" object on whichthe core classes are defined. This would be the JS prototype of the pershell script global.Module owner: jst@netscape.comTask owner: jband@netscape.com,vidur@netscape.comStatus: JBand to determine the memory used by the core classes.JBand, Vidur and Johnny to determine what could break with a super global.Bugs: 46703 Image LibraryDescription: We have anecdotal information that the image memorycache (not the network memory cache) is not being hit very often. We alsodon't know if the size of the cache is bounded and if it a memory flushlistener.Module owner: pnunn@netscape.comTask owner: syd@netscape.com(?)Status: Syd to work with Pam to analyze image memory cache usageand size limits.Bugs: 46704 CSS LoaderDescription: Analysis from dougt@netscape.com shows that weare loading the same CSS files from disk at startup time redundantly. TheCSSLoader should be caching compiled CSS style sheets so that we don'thit the disk. Chris' suspicion is that we aren't hitting the cache for@imported stylesheets. Why are we loading the CSS files multiple times?If the cache does exist, is it bounded? It needs to be a memory flush listener.Module owner: pierre@netscape.com,attinasi@netscape.comTask owner: pierre@netscape.comStatus: Pierre to investigate why we are loading the CSS filesmultiple times and not hitting the CSS Loader cache.Bugs: 46548 When to flush memoryDescription: When should the memory flushers be run? The currentthinking is to have a combination of a timer and an IsLowMemory predicate(requires hooking into malloc/free, new/delete for each platform) to determinewhen to run them.Task owner: warren@netscape.com,wade@netscape.comStatus: Wade to investigate implementing the IsLowMemory perdicate.Bugs: 44352 .xpt file loadingDescription: Currently we're loading more type library informationthan we necessarily use because of the way xpt files are created as partof the module build process. Better factoring of the xpt files could resultin less loading at startup time and less memory usage. Also, the type libraryinfo needs to be a memory flush listener.Module owner: jband@netscape.com,mccabe@netscape.comTask owner: jband@netscape.comStatus: JBand to investigate either better factoring of typelibsin xpt files or the idea of putting all of the individual small xpt filesinto a single zip file.Bugs: 46707 Networking memory/disk cacheDescription: We have anecdotal information that we're not hittingthe networking memory/disk caches that often. We need to do analysis ofcache hit rates.Module owner: neeti@netscape.comTask owner: gagan@netscape.comStatus: Gagan and Neeti to do analysisBugs: 46708 Component registry loadingDescription: We load and inflate the component registry at startuptime. We've heard anecdotally that the in-memory cost of the componentregistry is 1-3 megs. This hit could become worse if/when we implementRayW's new scheme for prog IDs. Need to see if we can use a better schemeto reduce bloat.Module owner: rayw@netscape.comTask owner: waterson@netscape.com,dougt@netscape.comStatus: Chris and Doug to do analysis of memory usage so wehave real numbers.Bugs: 46709 String bundlesDescription: StringKeysused by string bundle hashtables have showed up fairly high on the bloatblamelist. Each StringKey holds an AutoString which seems wasteful for the keysin the hashtable itself (the AutoStrings are useful during lookup whenthe key is stack allocated). We need to reduce the size of StringKeys.Also, could string bundles be arena allocated?Module owner: ?Task owner: warren@netscape.comStatus: Warren to look into alternatives for StringKeys andstring bundle allocation.Bugs: 46711, 46712 Bloatblame FEDescription: Currently bloatblame is a post-processing tool.We believe we can get much more useful information if we can get more real-timedata of module memory usage. Brendan has been working on the back-end ofthe real-time bloatblame. Wade and Pavlov are both looking into a front-endto display/graph the data.Module owner: brendan@netscape.comTask owner: wade@netscape.com,pavlov@netscape.comStatus: Brendan is on vacation and we believe that the currentlychecked in version does not implement all the back-end changes necessary.We may need to wait till Brendan returns.Bugs: 46714 Chrome cache analysisDescription: Dougt's analysis about redundant file loading atstartup time shows that we're also loading the same JS chrome file multipletimes. We need to figure out why the chrome cache isn't sharing compiledversions of the JavaScript.Module owner: waterson@netscape.comTask owner: waterson@netscape.comStatus: Chris to determine what's happening hereBugs: 46129 Mail/New bloat analysisDescription: Does mail/news have bloat analysis tasks that shouldgo on this list?Module owner: bienvenu@netscape.com,alecf@flett.orgTask owner: waterson@netscape.comStatus: Chris to get David or Alec to come to the meeting andsend us a list of tasks.Bugs: 46716 BiDi (Hebrew and Arabic) July 28 Submitted by Mike Kaply We have the code merged to the current level and arewaiting for the approval to check it in now that M17 and nsbeta2have branched. We will also be putting together a Windos binary based on the M17 drop. LDAP July 28 Submitted by Dan
