Serguei, *The problem:*
If someone run prelink utility while Java program is running DSO's mappings in it's /proc/<pid>/maps become messy. After prelink it contains entry like <addr> /lib64/libc-2.15.so (deleted) <addr> /lib64/libpthread-2.15.so.#prelink#.EECVts instead of normal <addr> /lib64/libc-2.15.so Here is the letter from Carlos, describing the problem in details: https://bugs.openjdk.java.net/browse/JDK-8038392 *The fix:* The fix allows SA to handle situation above. Also I fix longstanding issue - maps file parser in SA doesn't skip [stack*, [heap] etc entry and attempts to open it as a DSO *Testing:* I tested it manually with a different of prelink options (no prelink, prelink all, prelink some libraries only) -Dmitry On 2014-06-12 13:50, serguei.spit...@oracle.com wrote: > Hi Dmitry, > > There is no description of the fix. > Could you, please, provide one? > What did you basically wanted to achieve? > Also, how did the fix been tested? > It seems, a unit test would be nice to have. > > Thanks, > Serguei > > On 6/5/14 12:08 AM, Dmitry Samersoff wrote: >> http://cr.openjdk.java.net/~dsamersoff/JDK-8038392/webrev.02/ >> >> On 2014-05-20 17:47, Dmitry Samersoff wrote: >>> On 2014-04-07 16:56, Dmitry Samersoff wrote: >>>> Hi Everybody, >>>> >>>> Please review the patch >>>> >>>> http://cr.openjdk.java.net/~dsamersoff/JDK-8038392/webrev.02/ >>>> >>>> it's based on the patch contributed by Carlos Santos (see CR) and all >>>> credentials belong to him. >>>> >>>> -Dmitry >>>> >>> >> > -- Dmitry Samersoff Oracle Java development team, Saint Petersburg, Russia * I would love to change the world, but they won't give me the sources.
