Date Tue, 31 Oct 2006 14:11:29 GMT
     [ http://issues.apache.org/jira/browse/HARMONY-2016?page=all ]

Ivashin Sergey updated HARMONY-2016:
------------------------------------

    Attachment: H-2016.patch

The patch fixes 3 PMF Logger bugs.
To fix the last bug, new form of CompilationContext constructor is introduced to copy some
data from existing CompilationContext. This form used in inliner and escanalyzer to start
new compilation.

> There are 3 known related PMF Logger bugs:
> (1) concurrent write from different Jits
> When info stream is enabled (-Djit.arg.log=info) in server mode of Jitrino, resulting
file (log/info.log) is full of garbage, because of concurrent write to the file from SD1_OPT,SD2_OPT
and JET_CLINIT Jits.
> (2) enabling  stream for multiple instances of the same action
> For example, -Djit.arg.log.bp_regalloc=ct should enable ct stream for both instances
of bp_regalloc, but it does not.
> (3)  write with new CompilationContext in escanalyzer.cpp
> Log stream is not enabled for new compilation that starts by escanalyzer.cpp.
