Hi, I didn't find any bugs in gc_v4 at the moment,
Vera, its good to know the verifier found zero bugs in GCV4!
but this feature is really very useful especially if you modify gc_v4 or design a new gc. Of course, it needs to be improved and developed.
This brings up a good point. Harmony-dev needs to discuss the roadmap for DRLVM GC. I will start a discussion thread shortly.
Also I'm going to add feature to verify write barriers work.
Some comments. 1) There is no DRLVM GC that uses a write barrier currently. Assuming you have a write barrier verifier, how will you know it works? 2) I would like to see the design of the write barrier verifier discussed on harmony-dev mailing list before implementation is started. I am interested in using the proposed write verifier on DRLVM/MMTk.
The same way as in GC heap verification I use idea to hijack interface function concerning write barriers. This patch will be sent a bit later. Pleased to hear from you, Vera :)! -----Original Message----- From: news [mailto:[EMAIL PROTECTED] On Behalf Of Egor Pasko Sent: Saturday, July 15, 2006 9:37 AM To: [email protected] Subject: Re: [DRLVM] GC heap verification infrastructure On the 0x1A6 day of Apache Harmony Vera Volynets wrote: > ************* GC heap verification infrastructure *************** > Hi, > I have been working on implementing GC heap verification infrastructure > for Stop-The-World GC in DRLVM. > This infrastructure is intended be used with any stop-the-world GC > implementation, conforming to the GC-VM interface (described in gc.h and > vm_gc.h), with only a minor GC-VM interface change. > It works on Windows and Linux ia32 platforms. cool feature! did you find any bugs in DRLVM while testing? do you have plans/ideas for future development of the tool? > [...] > > *Patch contents* > This is an individual contribution, and it was prepared according to the > requirements of Apache cleanroom process; the size of two files all in > all is about 30kb (161 and 585 lines). > -Patch Add-function-to-gc-interface.txt oh, I found it!
