* | * generic/tclBasic.c:Miguel Sofer2007-11-101-3/+3
| | | | | | | | | | | | | | | | | | * generic/tclInt.h: * unix/tclUnixInit.c: * win/tclWin32Dll.c: restore simpler behaviour for stack checking, not adaptive to stack size changes after a thread is launched. Consensus is that "nobody does that", and so it is not worth the cost.

| | | | | | | | | | | | | | | | | | | | | | * win/tclWin32Dll.c: Rewrote the Windows stack checking algorithm to use information from VirtualQuery to determine the bound of the stack. This change fixes a bug where the guard page of the stack was never restored after an overflow. It also eliminates a nasty piece of assembly code for structured exception handling on mingw. It introduces an assumption that the stack is a single memory arena returned from VirtualAlloc, but the code in MSVCRT makes the same assumption, so it should be fairly safe.
* | * generic/tclBasic.c:Miguel Sofer2007-11-101-6/+90
| | | | | | | | | | | | | | | | | | | | | | * generic/tclInt.h: * unix/tclUnixInit.c: * unix/tclUnixPort.h: * win/tclWin32Dll.c: modify the stack checking algorithm to recheck in case of failure. The working assumptions are now that (a) a thread's stack is never moved, and (b) a thread's stack can grow but not shrink. Port to windows - could be more efficient, but is already cheaper than it was.

[Patch 1202052] * tests/unixNotfy.test: don't run unthreaded tests on Darwin since notifier may be using threads even in unthreaded core. * unix/tclUnixPort.h: * unix/tcl.m4 (Darwin): test for thread-unsafe realpath durning configure, as Darwin 7 and later realpath is threadsafe. * macosx/Makefile: enable configure caching. * unix/configure.in: wrap tclConfig.h header in #ifndef _TCLCONFIG so that it can be included more than once without warnings from gcc4.0 (as happens e.g. when including both tclInt.h and tclPort.h) * macosx/tclMacOSXBundle.c: * unix/tclUnixChan.c: * unix/tclLoadDyld.c: * unix/tclUnixInit.c: fixed gcc 4.0 warnings. * unix/configure: autoconf-2.59 * unix/tclConfig.h.in: autoheader-2.59 * generic/tclIntDecls.h: * generic/tclIntPlatDecls.h: * generic/tclStubInit.c: make genstubs

To test this code in the common case of a single-processor machine, a 'testwincpuid' command was added to tclWinTest.c, and a test case in platform.test. Thanks to Jeff Godfrey and Richard Suchenwirth for reporting this bug. [Bug #976722]

* * win/tclWin32Dll.c (TclpCheckStackSpace, squelch_warnings):mdejong2003-01-251-41/+51
| | | | | | | | | | | | | | * win/tclWinChan.c (Tcl_MakeFileChannel, squelch_warnings): * win/tclWinFCmd.c (DoRenameFile, DoCopyFile, squelch_warnings): Re-implement inline ASM SEH handlers for gcc. The esp and ebp registers are now saved on the stack instead of in global variables so that the code is thread safe. Add additional checks when TCL_MEM_DEBUG is defined to be sure the values were recovered from the stack properly. Remove squelch_warnings functions and add a dummy call in the handler methods to squelch compiler warnings.
* * win/configure:mdejong2003-01-251-6/+10
| | | | | | | | | | | | | | | * win/configure.in: Define HAVE_ALLOCA_GCC_INLINE when we detect that no alloca function is found in malloc.h and we are compiling with GCC. Remove HAVE_NO_ALLOC_DECL define. * win/tclWin32Dll.c (TclpCheckStackSpace): Don't define alloca as a cdecl function. Doing this caused a tricky runtime bug because the _alloca function expects the size argument to be passed in a register and not on the stack. To fix this problem, we use inline ASM when compiling with gcc to invoke _alloca with the size argument loaded into a register.
* * win/configure: Regen.mdejong2003-01-241-7/+20
| | | | | | | | | | | * win/configure.in: * win/tclWin32Dll.c (TclpCheckStackSpace): Rework the SEH exception handler logic to avoid using the stack since alloca will modify the stack. This was causing a nasty bug that would set the exception handler to 0 because it tried to pop the previous exception handler off the top of the stack.
