| | | | | | | | | | | | | | | | | | | | | | | | | | The common technique for printing out a pointer has been to cast to a long and use the "%lx" printf modifier. This is incorrect on Win64 where casting to a long truncates the pointer. The "%p" formatter should be used instead. The problem as stated by Tim: > Unfortunately, the C committee refused to define what %p conversion "looks > like" -- they explicitly allowed it to be implementation-defined. Older > versions of Microsoft C even stuck a colon in the middle of the address (in > the days of segment+offset addressing)! The result is that the hex value of a pointer will maybe/maybe not have a 0x prepended to it. Notes on the patch: There are two main classes of changes: - in the various repr() functions that print out pointers - debugging printf's in the various thread_*.h files (these are why the patch is large) Closes SourceForge patch #100505.

| | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes possible overflow in the use of PyOS_GetLastModificationTime in getmtime.c and Python/import.c. Currently PyOS_GetLastModificationTime returns a C long. This can overflow on Win64 where sizeof(time_t) > sizeof(long). Besides it should logically return a time_t anyway (this patch changes this). As well, import.c uses PyOS_GetLastModificationTime for .pyc timestamping. There has been recent discussion about the .pyc header format on python-dev. This patch adds oveflow checking to import.c so that an exception will be raised if the modification time overflows. There are a few other minor 64-bit readiness changes made to the module as well: - size_t instead of int or long for function-local buffer and string length variables - one buffer overflow check was added (raises an exception on possible overflow, this overflow chance exists on 32-bit platforms as well), no other possible buffer overflows existed (from my analysis anyway) Closes SourceForge patch #100509.

| | | | | | | | | | | | This patch fixes a problem on AIX with the signed int case code in getargs.c, after Trent Mick's intervention about MIN/MAX overflow checks. The AIX compiler/optimizer generates bogus code with the default flags "-g -O" causing test_builtin to fail: int("10", 16) <> 16L. Swapping the two checks in the signed int code makes the problem go away. Also, make the error messages fit in 80 char lines in the source.
* Urmpf. Quality control on this patch lapsed a bit. :-(Guido van Rossum2000-06-281-2/+6
| | | | | | | | | | | The depth field was never decremented inside w_object(), and it was never initialized in PyMarshal_WriteObjectToFile(). This caused imports from .pyc files to fil mysteriously when the .pyc file was written by the broken code -- w_object() would bail out early, but PyMarshal_WriteObjectToFile() doesn't check the error or return an error code, and apparently the marshalling code doesn't call PyErr_Check() either. (That's a separate patch if I feel like it.)

| | | | | | | | | | | | | | | | | | | | | | | | Various small fixes to the builtin module to ensure no buffer overflows. - chunk #1: Proper casting to ensure no truncation, and hence no surprises, in the comparison. - chunk #2: The id() function guarantees a unique return value for different objects. It does this by returning the pointer to the object. By returning a PyInt, on Win64 (sizeof(long) < sizeof(void*)) the pointer is truncated and the guarantee may be proven false. The appropriate return function is PyLong_FromVoidPtr, this returns a PyLong if that is necessary to return the pointer without truncation. [GvR: note that this means that id() can now return a long on Win32 platforms. This *might* break some code...] - chunk #3: Ensure no overflow in raw_input(). Granted the user would have to pass in >2GB of data but it *is* a possible buffer overflow condition.

| | | | | | | | | | | | | As I really do not have anything better to do at the moment, I have written a patch to Python/marshal.c that prevents Python dumping core when trying to marshal stack bustingly deep (or recursive) data structure. It just throws an exception; even slightly clever handling of recursive data is what pickle is for... [Fred Drake:] Moved magic constant 5000 to a #define. This closes SourceForge patch #100645.

| | | | | | Limit the 'b' formatter of PyArg_ParseTuple to valid values of an unsigned char, i.e. [0,UCHAR_MAX]. It is expected that this is the common usage of 'b'. An OverflowError is raised if the parsed value is outside this range.

| | | | | | | | | | | | | | | | | | who wrote: Here's the new version of thread_nt.h. More particular, there is a new version of thread lock that uses kernel object (e.g. semaphore) only in case of contention; in other case it simply uses interlocked functions, which are faster by the order of magnitude. It doesn't make much difference without threads present, but as soon as thread machinery initialised and (mostly) the interpreter global lock is on, difference becomes tremendous. I've included a small script, which initialises threads and launches pystone. With original thread_nt.h, Pystone results with initialised threads are twofold worse then w/o threads. With the new version, only 10% worse. I have used this patch for about 6 months (with threaded and non-threaded applications). It works remarkably well (though I'd desperately prefer Python was free-threaded; I hope, it will soon).

| | | | | | | | | | For more comments, read the patches@python.org archives. For documentation read the comments in mymalloc.h and objimpl.h. (This is not exactly what Vladimir posted to the patches list; I've made a few changes, and Vladimir sent me a fix in private email for a problem that only occurs in debug mode. I'm also holding back on his change to main.c, which seems unnecessary to me.)
* A bit of cleanup:Guido van Rossum2000-05-031-34/+5
| | | | | | | | | - When 'import exceptions' fails, don't suggest to use -v to print the traceback; this doesn't actually work. - Remove comment about fallback to string exceptions. - Remove a PyErr_Occurred() check after all is said and done that can never trigger. - Remove static function newstdexception() which is no longer called.
* Brian Hooper <brian_takashi@hotmail.com>:Fred Drake2000-05-031-0/+32
| | | | | | | Added 'u' and 'u#' tags for PyArg_ParseTuple - these turn a PyUnicodeObject argument into a Py_UNICODE * buffer, or a Py_UNICODE * buffer plus a length with the '#'. Also added an analog to 'U' for Py_BuildValue.

| | | | | | | | | | return 0 (exceptions don't match). This means that if an ImportError is raised because exceptions.py can't be imported, the interpreter will exit "cleanly" with an error message instead of just core dumping. PyErr_SetFromErrnoWithFilename(), PyErr_SetFromWindowsErrWithFilename(): Don't test on Py_UseClassExceptionsFlag.

* initerrors(): Remove this function. String-based standard exceptionsBarry Warsaw2000-05-021-96/+4
| | | | | | | | | | | | | are no longer supported (i.e. -X option is removed). _PyBuiltin_Init_1(): Don't call initerrors(). This does mean that it is possible to raise an ImportError before that exception has been initialized, say because exceptions.py can't be found, or contains bogosity. See changes to errors.c for how this is handled. _PyBuiltin_Init_2(): Don't test Py_UseClassExceptionsFlag, just go ahead and initialize the class-based standard exceptions. If this fails, we throw a Py_FatalError.

* Marc-Andre Lemburg:Guido van Rossum2000-05-011-8/+20
| | | | | | | | | | | Changed all references to the MAGIC constant to use a global pyc_magic instead. This global is initially set to MAGIC, but can be changed by the _PyImport_Init() function to provide for special features implemented in the compiler which are settable using command line switches and affect the way PYC files are generated. Currently this change is only done for the -U flag.
* Marc-Andre Lemburg:Guido van Rossum2000-05-011-0/+1
| | | | Added Py_UnicodeFlag for use by the -U command line option.
