This week is UI review; would anyone like to put forward something to 
discuss?

Otherwise, there's a round table.

I have a VNC session containing frysk CVS from this morning setup. Let
me (mjw on irc #frysk irc.gimp.net) know if anyone wants something added
to the machine for a demonstration.

Cheers,

Mark

Technical discussion: cni vs jni
See and please follow up the e-mail: 
http://sources.redhat.com/ml/frysk/2007-q3/msg00084.html

Round Table (Ordered roughly by last initial of first name):

Teresa:

Working on a mechanism to identify debug that is missing.
E.x.: given /bin/bash, that /usr/lib/debug/usr/bin/bash.debug and hence 
bash-debuginfo should be installed
Current code is calling an elfutils find-debuginfo method directly; 
investigating instead modeling things more after the builder-pattern 
where elfutils would notify (call-back) frysk of the debug-info it is 
looking at.

[side bar: roland's indicated that the code is under review; firstly 
making mechanisms that simplify the task of frysk implementing the 
debug-info call back function (e.g., making a crc-check method 
available); and secondly exploring more efficient ways of confirming 
that the debug info matches.]

Sami:

Printing values of variables in a stack frame.  ezannoni asked if this 
was hpd specific, sami answered that it was the oposite, removing hpd 
specific assumptions from the existing code.  Has one known 64-bit bug 
remaining.

Mark:

Fixing problem where inserted breakpoints are visible when examining 
memory contents - users don't expect to see breakpoint instructions in 
their code.  Adding a Task.getRawMemory which will contain what is 
really in memory vs getMemory which is what the user thinks is there.

Rick:

More work cleaning up the cdtparser - current parser doesn't handle 
macros well; worked around.
Other misc gui fixes.
Re-investigating option of moving to the CDT's latest parser; last time 
this was investigated it was determined that it wasn't technically 
possible as the parser had been heavely embedded into the CDT.
Working on moving the session concept out of the gui and into the core 
so that it can be shared with the HPD.

Phil:

Adding x86-64 core-file tests so that code exercised on x86.
Conducting review of current fcore code.

[side bar: see enable 32-X-64 tests 
http://sources.redhat.com/ml/frysk/2007-q3/msg00088.html ]

Tim:

Task/Proc stuff of HPD; for instance a Manager to assign each task/proc 
HPD numbers.  E.g., 0.0 is the first processes first task.
Cagney asked where the code is being added - frysk.rt - cagney noted 
that that frysk.rt code eventually migrates to a more permanent home 
(e.g., frysk.stack, frysk.debuginfo, ...).

Adam:

Improving robustness of display command; which in turn means adding more 
action-point related commands to the HPD.

cagney:

Avoiding blockades.
Tracking down memory smash problems in dwfl/elf.
(Was trying to clean up the exception throw/catch code as often catch 
code was discarding, instead of re-throwing, exceptions)

[Sidebar: dwfl/elf bindings have memory corruption problems; for 
instance, when the object returned by DwflModule.getElf is freed it 
could close out the dwfl's elf object.

Apologies: Stan, Chris, Kiris, Nurdin, Mike.
