ysr [Tue, 26 Apr 2011 21:17:24 -0700] rev 9342
7039089: G1: changeset for 7037276 broke heap verification, and related cleanups Summary: In G1 heap verification, we no longer scan perm to G1-collected heap refs as part of process_strong_roots() but rather in a separate explicit oop iteration over the perm gen. This preserves the original perm card-marks. Added a new assertion in younger_refs_iterate() to catch a simple subcase where the user may have forgotten a prior save_marks() call, as happened in the case of G1's attempt to iterate perm to G1 refs when verifying the heap before exit. The assert was deliberately weakened for ParNew+CMS and will be fixed for that combination in a future CR. Also made some (non-G1) cleanups related to code and comments obsoleted by the migration of Symbols to the native heap. Reviewed-by: iveresov, jmasa, tonyp

tonyp [Tue, 19 Apr 2011 15:46:59 -0400] rev 9334
7011855: G1: non-product flag to artificially grow the heap Summary: It introduces non-product cmd line parameter G1DummyRegionsPerGC which indicates how many "dummy" regions to allocate at the end of each GC. This allows the G1 heap to grow artificially and makes concurrent marking cycles more frequent irrespective of what the application that is running is doing. The dummy regions will be found totally empty during cleanup so this parameter can also be used to stress the concurrent cleanup operation. Reviewed-by: brutisso, johnc
