* | faulthandler: add Windows exception handlerVictor Stinner2016-03-235-77/+253
| | | | | | | | | | | | Issue #23848: On Windows, faulthandler.enable() now also installs an exception handler to dump the traceback of all Python threads on any Windows exception, not only on UNIX signals (SIGSEGV, SIGFPE, SIGABRT).
* | Issue #23848: Expose _Py_DumpHexadecimal()Victor Stinner2016-03-232-9/+23
| | | | | | | | This function will be reused by faulthandler.
* | Cleanup hashtable.hVictor Stinner2016-03-234-81/+82
| | | | | | | | | | | | | | | | | | | | | | | | Issue #26588: * Pass the hash table rather than the key size to hash and compare functions * _Py_HASHTABLE_READ_KEY() and _Py_HASHTABLE_ENTRY_READ_KEY() macros now expect the hash table as the first parameter, rather than the key size * tracemalloc_get_traces_fill(): use _Py_HASHTABLE_ENTRY_READ_DATA() rather than pointer dereference * Remove the _Py_HASHTABLE_ENTRY_WRITE_PKEY() macro * Move "PKEY" and "PDATA" macros inside hashtable.c
* | Issue #26588:Victor Stinner2016-03-233-12/+31
| | | | | | | | | | | | | | * Optimize tracemalloc_add_trace(): modify hashtable entry data (trace) if the memory block is already tracked, rather than trying to remove the old trace and then add a new trace. * Add _Py_HASHTABLE_ENTRY_WRITE_DATA() macro
* | Issue #26588:Victor Stinner2016-03-234-12/+29

* | Issue #26588: Optimize tracemalloc_realloc()Victor Stinner2016-03-231-1/+6
| | | | | | | | No need to remove the old trace if the memory block didn't move.
* | Makefile: change default value of TESTTIMEOUT from 1 hour to 15 minVictor Stinner2016-03-231-1/+1
| | | | | | | | | | | | The whole test suite takes 6 minutes on my laptop. It takes less than 30 minutes on most buildbots. The TESTTIMEOUT is the timeout for a single test file.

| | | | | | | | | | libregrtest: add a watchdog to run_tests_multiprocess() using faulthandler.dump_traceback_later().
* | _warnings.warn_explicit(): try to import warningsVictor Stinner2016-03-221-14/+36
| | | | | | | | | | | | Issue #26592: _warnings.warn_explicit() now tries to import the warnings module (Python implementation) if the source parameter is set to be able to log the traceback where the source was allocated.
* | Implement finalizer for os.scandir() iteratorVictor Stinner2016-03-221-17/+47
| | | | | | | | | | | | | | | | Issue #26603: * Implement finalizer for os.scandir() iterator * Set the source parameter when emitting the ResourceWarning warning * Close the iterator before emitting the warning

| | | | | | | | | | | | | | | | Issue #26604: * Add a new optional source parameter to _warnings.warn() and warnings.warn() * Modify asyncore, asyncio and _pyio modules to set the source parameter when logging a ResourceWarning warning

| * Enhance _tracemalloc debug modeVictor Stinner2016-03-221-1/+1
| | | | | | | | Issue #26588: Enhance assertion in set_reentrant()
| * Fix _tracemalloc start/stopVictor Stinner2016-03-221-14/+0
| | | | | | | | | | | | | | | | | | Issue #26588: Fix _tracemalloc start/stop: don't play with the reentrant flag. set_reentrant(1) fails with an assertion error if tracemalloc_init() is called first in a thread A and tracemalloc_start() is called second in a thread B. The tracemalloc is imported in a thread A. Importing the module calls tracemalloc_init(). tracemalloc.start() is called in a thread B.

* | regrtest: add time to outputVictor Stinner2016-03-222-6/+19
| | | | | | | | | | Timestamps should help to debug slow buildbots, and timeout and hang on buildbots.
* | Add C functions _PyTraceMalloc_Track()Victor Stinner2016-03-225-11/+300
| | | | | | | | | | | | | | | | Issue #26530: * Add C functions _PyTraceMalloc_Track() and _PyTraceMalloc_Untrack() to track memory blocks using the tracemalloc module. * Add _PyTraceMalloc_GetTraceback() to get the traceback of an object.
* | tracemalloc now supports domainsVictor Stinner2016-03-225-104/+388
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #26588: * The _tracemalloc now supports tracing memory allocations of multiple address spaces (domains). * Add domain parameter to tracemalloc_add_trace() and tracemalloc_remove_trace(). * tracemalloc_add_trace() now starts by removing the previous trace, if any. * _tracemalloc._get_traces() now returns a list of (domain, size, traceback_frames): the domain is new. * Add tracemalloc.DomainFilter * tracemalloc.Filter: add an optional domain parameter to the constructor and a domain attribute * Sublte change: use Py_uintptr_t rather than void* in the traces key. * Add tracemalloc_config.use_domain, currently hardcoded to 1
* | Remove _Py_hashtable_delete()Victor Stinner2016-03-222-8/+3
| | | | | | | | | | | | Issue #26588: Remove _Py_hashtable_delete() from hashtable.h since the function is not used. Keep the C code in hashtable.c as commented code if someone needs it later.
* | Simplify implementation of hashtable.cVictor Stinner2016-03-223-66/+17
| | | | | | | | | | | | | | | | | | | | | | Issue #26588: Remove copy_data, free_data and get_data_size callbacks from hashtable.h. These callbacks are not used in Python and makes the code more complex. Remove also the _Py_HASHTABLE_ENTRY_DATA_AS_VOID_P() macro which uses an unsafe pointer dereference (can cause memory alignment issue). Replace the macro usage with _Py_HASHTABLE_ENTRY_READ_DATA() which is implemented with the safe memcpy() function.

| | | | | | | | | | | | | | | | | | Issue #26588: hashtable.h now supports keys of any size, not only sizeof(void*). It allows to support key larger than sizeof(void*), but also to use less memory for key smaller than sizeof(void*).

* | | Add socket finalizerVictor Stinner2016-03-212-18/+56
| | | | | | | | | | | | | | | | | | | | | Issue #26590: Implement a safe finalizer for the _socket.socket type. It now releases the GIL to close the socket. Use PyErr_ResourceWarning() to raise the ResourceWarning to pass the socket object to the warning logger, to get the traceback where the socket was created (allocated).
