and reconfigure and rebuild. Then run the app on the bloaturls list of urls with the environment variable XPCOM_MEM_REFCNT_LOG set to 1 to dump bloat and leak summaries to stdout:

   export XPCOM_MEM_REFCNT_LOG=1

   <appname> resource:///res/bloatcycle.html > bloat.log

If you want to compare two runs (e.g. test a change) do something like this:

   export XPCOM_MEM_REFCNT_LOG=1

  <appname> resource:///res/bloatcycle.html > a.out

   <appname> resource:///res/bloatcycle.html > b.out

  bloatdiff.pl a.out b.out

With a non-debug browser build on Linux from CVS tip as of 2007-07-05 the dump of bloatcycle.html test exceeds 10 GB. Thus if 20+ GB of the disk space is not available, use gzip when running the tests to compress the dumps down to 100 MB or so:

   <appname> resource:///res/bloatcycle.html | gzip > a.out.gz

   <appname> resource:///res/bloatcycle.html | gzip > b.out.gz

   bloatdiff.pl 'zcat a.out.gz|' 'zcat b.out.gz|'
