How does NTVDM allocate memory at address 0 for the V86 IDT? Is it different in reactos vs. Windows? NtAllocateVirtualMemory won't allow that. Melissa

In fact, cleanup handlers need not be used at all. This approach requires the NPTL r ather than the LinuxThreads, API and is orthogonal to the previous issue about removing thread cancellation (that was a runtime issue present with NPTL regardless of which header one compiles against). Instead of calling _pthread_cleanup_push_defer(), we can store a __pthread_unwind_buf_t in the exception context and call __sigsetjmp() and __pthread_register_cancel_defer(). If __sigsetjmp() returns from a longjmp(), then we call dce_pthread_test_exit_np() to test whether the thread was cancelled, and set the current exception to pthread_cancel_e if necessary. No cleanup handler is necessary. The trick is that the code that raises an exception needs to call the internal API __pthread_unwind(), rather than longjmp(). Of course this ends up calling longjmp() anyway but hopefully does the right thing with respect to any other cleanup handlers that are registered. Another idea is to use the _Unwind_XXX API, but this strikes me as a little ambitious for now and I don't have any desire to interleave C++ and DCE exceptions. /* * For the NPTL API we share a setjmp/longjmp buffer between the * pthreads cancellation and DCE exception handling APIs. * * Note that we never actually call the cancellation function, we * just change the current exception context directly; this is the * same as calling dce_ptdexc_raise(&pthread_cancel_e) except that * __pthread_unwind() is not called. */ #define dce_exc_cleanup_push(cu, routine, arg) do \ { \ __exc_occured = __sigsetjmp((struct __jmp_buf_tag *)(cu)->__cancel_buf.__cancel_jmp_buf, 0); \ if (__exc_occured) \ { \ void *__status; \ \ if (dce_pthread_test_exit_np(&__status) == PTHREAD_STATUS_EXIT_NP \ && __status == PTHREAD_CANCELED) \ __exc_ctxt.exc = &pthread_cancel_e; \ } \ else \ { \ __pthread_register_cancel_defer(&(cu)->__cancel_buf); \ } \ } while (0) #define dce_exc_cleanup_pop(cu, execute) do \ { \ __pthread_unregister_cancel_restore(&(cu)->__cancel_buf); \ } while (0) /* make this a NOOP because we called it above */ #define dce_exc_setjmp(jmpbuf, val) /* we call __pthread_unwind() directly from dce_ptdexc_raise() */ #undef dce_exc_longjmp -- Luke -- ----- End forwarded message ----- -- -- lkcl.net - mad free software computer person, visionary and poet. --

Summer of Code

by Nate DeSimone

Hello Everyone, I've been lurking on this list for a few years and I'm considering applying for the Google Summer of Code 2006. I am a Computer Systems Engineer at Rensselaer Polytechnic Institute, just finishing up my junior year. My GPA is 3.06, and I have taken a good amount of computer science courses including Data Structures and Algorithms and Database Systems. I have programmed in C, C++, C#, VB, Perl, PHP, Java and Javascript before. I'm also familiar with Sybase and MySQL and HTML design. I have also done some Win32 programming on my spare time, you can look at some of my projects at: http://www.rpi.edu/~desimn <http://www.rpi.edu/%7Edesimn> I have never done kernel mode programming before and I'm not certain if I'm quite ready for it yet, so if possible I would like to stay in the user mode space. The enhance explorer and add "wow factor" sounds interesting to me. Is there anything else that would involve at least almost all user mode work? Also I was wondering, approximately how many hours would you expect me to put forth every week should I be accepted? Thank You, Nate DeSimone

need help debugging

by Peter Quiring

Hi all, I'm new to ROS but I've had a few patches accepted to Wine. I'm having difficulty with the website and I can't seem to login (even after enabling multisession) so I can't use bugzilla or the forums. So anyways, I've got ROS to compile (RosBE is great!)/build/install on two systems but I'm getting the following problems on one system (Dell Inspiron 5150 Laptop): During install it shows a 17592185991168 MB unused space partition after my 60 GB FAT32 partition. But install still works okay. During 1st boot I get a bsod, I don't have a COM port (USB only) so I tried to use the SCREEN output option but it's too fast to read. I've try to use the FILE option but only 600+ bytes are written to the debug.log file. I know the cache_manager isn't being flushed because everytime it crashes the contents of the folders in "Documents & settings" folder are corrupt (ie: "All Users.Reactos", etc.) So my question is : How can I disable the cache_manager? Or can I place sync() commands somewhere in the source for testing. (is there such a function available?). The bsod seems to be related to gdi issues during creating the primary surface. Somewhere the DeviceObject for the screen is NULL and is not caught till it causes a GPE much later. I'll give a little info that I've written down. /ntoskrnl/io/irp.c:570 - GPE /ntoskrnl/io/irp.c:911 /subsystems/win32/win32k/objects/dc.c:693 /subsystems/win32/win32k/ntuser/winsta.c:348 /subsystems/win32/win32k/ntuser/guicheck.c:57 /subsystems/win32/win32k/objects/dc.c:853 /subsystems/win32/win32k/ntuser/windc.c:121 /subsystems/win32/win32k/ntuser/windc.c:441 /subsystems/win32/win32k/ntuser/windc.c:529 /subsystems/win32/win32k/ntuser/windc.c:101 /ntoskrnl/ke/traps.c:306 /dll/win32/user32/windows/dialog.c:696 Hope this helps. I was using the lastest SVN at the time (21738 I think). Thanks. Peter Quiring

two new bugs in newer ROS

by theUser BL

Hi! There existing two bugs from which I know, which existing not in older SVN/CVS-Snapshot ROS versions. Windows Tetris don't show the Highscore correct. With build 21549 there was still all ok. But with 21639 and all above the Highscore shows only curios symbols as text. AbiWord no longer runs. On build 21323 still all runs correct. But with 21549 the complete ROS hangs up. It ends with "A problem has been detected and ReactOS has been shut down to prevent damage to your computer APC_INDEX_MISMATCH" And so on. Don't know if in the current CVS/SVN-Version the bugs are already fixed. But they existing for some days/weeks. Greatings theuserbl
