Failed To Get Thread Context For Suspended Thread Handle


I was successful as just ignoring and trying again "later". Intel learned that the hard way when they had to recall the Pentium chip / provide workaround for compiler vendors due to the infamous FP bug. Explicit context Because thread creation and thread joining may occur in different contexts, it may be desirable to state the context explicitly to the thread's entry point function. The contents is stored in user-mode This is why you think the value is not-null but in the stale contents it is still null. http://qaisoftware.com/failed-to/failed-to-create-pdf-context-delegate.html

How does Decommission (and Revolt) work with multiple permanents leaving the battlefield? Never say never. :-)> You come across to me as someone who believes MSFT is a corp which has one of the best business practicesI didn't say that. Some platforms have a minimum thread stack size. In Concurrent Programming on Windows, he explains how to design, implement, and maintain large-scale concurrent programs, primarily using C# and C++ for Windows.   Duffy aims to give application, system, and https://supportforums.blackberry.com/t5/BlackBerry-Enterprise-Service-10/Delay-in-receiving-mail-on-device/td-p/1303631

That's rather trivial, though, compared to apps that use Boehm GC - they would also need to be updated and rebuilt (the GC currently does not expect SuspendThread / GetThreadContext to There is no way one can protect user mode code from interruption by a kernel APC (this is what SuspendThread is).

  • To handle alarms in threads, set up a signal handler in the main thread, and then use "THREAD SIGNALLING" to relay the signal to the thread: # Create thread with a
  • GC in this case was MPS.I'm disappointed that MS won't fix this bug.
  • I'm not touching the context in anyway, which is what hijacking typically means.
  • Last I checked, even their TBB team responded to my queries promptly and some changes were made to the way TBBMalloc allocates/deallocates memory.
  • SetThreadContext is not a good idea.CONTEXT_SERVICE_ACTIVE - if this comes back set, then the thread was already in the kernel, taking care of syscall.

Signal names and (positive) signal numbers are the same as those supported by kill().

Use a tracing tool like strace to trace the system calls and see which one is failing and why. –D.Shawley Aug 10 '10 at 12:36 @Shawley: Hmm.

Most other apps would be completely indifferent to the changes.Put it another way - is it instead better to break apps that rely on documented features such as GetThreadContext? this contact form In my case the code isn't time-critical when I need to do this (in order to generate a stack trace from a debugger). –500 - Internal Server Error Sep 25 '14 Hedden > threads-2.12 > threads Download: threads-2.12.tar.gz Dependencies Annotate this POD CPAN RT Open 0 View/Report Bugs Module Version: 2.12 Source NAME VERSION WARNING SYNOPSIS DESCRIPTION EXITING A THREAD Attached Thumbnails Edited by DeathAngle, 15 October 2014 - 12:34 AM.

A return value of zero indicates the system default stack size was used for the thread. $old_size = threads->set_stack_size($new_size); Sets a new default per-thread stack size, and returns the previous setting. A 64-bit application can retrieve the context of a WOW64 thread using the Wow64GetThreadContext function. Just another thing -- I'm not hijacking the thread. have a peek here Preserving Vertices How should I respond to absurd observations from customers during software product demos?

Because (in my opinion), Microsoft does not have resources to fix all bugs in its products (again as any other company producing commercial software).By "Microsoft did none of those", I would've Resumethread However, this doesn't work in WOW64 mode because it isn't supported.On Win8, CONTEXT_EXCEPTION flags are supported both under native 32-bit and WOW64 modes.Am I correct?

Keeping in mind the number of affected apps would've been minute (since it's only affecting JVM on IA64), it got the attention it needed because it's Java.By your logic where compromise

Some people on StackOverflow even say that this is not possible. BTW, I'm just curious, is there a web form or e-mail address or anything else open to general public specifically created to report bugs in Intel processors? > MSFT is definitely Is it not affected by this bug then? Rtlcapturecontext This is not a security vulnerability because all kernel mode code is trusted.

It was purely with GetThreadContext returning stale info. The names RIM and BlackBerry are registered Trademarks of BlackBerry Inc. For example does the problem happen if the project is built without optimizations perhaps? Correcting this by changing "Eip" to "Rip" won't fix the build, however, as there are other 64-bit incompatibilities.

There were some issues with this approach (I don't recall the details) but it works. For example WinAPI includes tons of high level stuff, really high level. Edited by swayz, 19 November 2014 - 01:25 AM. This would work too, but MSDN docs need to be updated to reflect such changes.
