The
OS/2 Task Manager by Chris Graham
Hi All.
Knut St. Osmundsen has released a new Task
Manager for OS/2 Warp and uploaded the file on Hobbes. I just tested it on my Warp Client version 4.5 (Warp 4.0 +
FP13) and this alpha release runs fine. You can get this file here:

Technical data
kTaskMgr v0.0.2
alpha preview -- Knut St. Osmundsen - 29 Apr 2000
Features:
o kTaskMgr is a nice little tool which will present information
on OS/2,
processes mainly using the DosQuerySysState API.
This currently includes information on processes, modules
and open files.
o It will allow you to kill processes. Two different
methods for killing
processes are provided:
1. The menuitem "Kill"
will try kill the process using
the DosKillProcess
API.
2. The menuitem "kill -9"
will try use the XF86SUP.SYS
device drivers
"death" method.
Features to come:
o Information about shared memory and semaphores.
o Map over the shared memory.
o I hoped it should be possible to change priority
on processes too, using
the DosSetPrioirty API. But, this API requires the process
specified to
be a decentant of the process issuing the call. This
functionality may
though be provided later by using win32k.sys to change
the priority.
(Win32k.sys will then provide a simple IOCtl to change
the priority of
a single thread slot, not process.)
Fixed bugs
v0.0.2:
o Not all modules (especially dlls) are reported
by DosQuerySysState
on my fixpack 13 machine.
Known bugs:
o There are some SFN which aren't found due to the bugs in DosQuerySysState
on system older that Warp4 fixpack 10/13.
The SFN pages are there by not necessarily correct.
So everyone is
recommend to update their Warp 4 systems to a fixpack
level of 10 or
above.
o kill -9 don't seem to work on my Warp Fixpack 13 machine.
o ...
Bugs/Features found in the DosQuerySysState API:
BUGBUG! - ctSft isn't correct, or rather Sft records are missing!!!
(qsFrec_t)
The number of qsSft_t records is always 1, no matter
what the
ctSft member says!
This is verified! The defect is located
in _qsReadMFT. When
writing the qsSft_t records the record pointer is always
initialized to _pCurCache in each iteration. This is
probably
correct, but _pCurCache is _NOT_ changed during the
iteration.
With the excelent result that the next Sft record overwrites
the previous one.
Solution: To move the call to _qsUpdatePtrs
into the loopbody,
after
the Sft record is written.
This
way _pCurCache will be updated at end of each
iteration.
This is a problem on Aurora, Warp 4 and Warp 3.
It seems like it's corrected in warp
4 fixpack 10, or at least it's
working with fixpack 13 exactly as I've described it!
(Probably
JR12792 or JR12762.)
FEATURE/BUGBUG: cFH isn't correct - it don't match with the
number of
entries in the pFSRec array. (qsProc_t)
This is verified! There is a "bug"
in the _qsProcFS worker (this
is the function which generates the SFT table pointed
to by pFSRec).
cFH is set to JFN_Length by _qsReadPtda. While _qsProcFS
skips the
entries containing 0xFFFF (unused handle placeholder).
This way the cFH is really the maximum number of handles
and the
size of the pFSRec table has to be determined by checking
pointers
to the next structure. Thread records are by specifications
following the FS records, pointer to these is used to
do this.
Note. JFN is not equal to the index into the SFN table due to this bug.
This is a problem on Aurora, Warp 4 and Warp 3.
It seems like it's corrected in warp
4 fixpack 10, or at least it's
working with fixpack 13. (Probably JR12792 or JR12762.)
BUGBUG: When testing kTaskMgr on Warp fixpack 13 not all DLL are reported for
some reason. This bug is currently unexplored.
