Victor Stinner b8d927266d Issue #26588: Don't call tracemalloc_init() at module initilization 
So it's possible to get debug messages in test_tracemalloc.

Victor Stinner 84aab09421 Issue #26588: add debug traces 
Try to debug random failure on buildbots.
 2016-03-22 16:13:31 +01:00
Victor Stinner 24f949e10c regrtest: add time to output 
Timestamps should help to debug slow buildbots, and timeout and hang on
buildbots.

Victor Stinner 10b73e1748 Add C functions _PyTraceMalloc_Track() 
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.

Victor Stinner e492ae50e2 tracemalloc now supports domains 
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

Victor Stinner 58100059ac Remove _Py_hashtable_delete() 
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.
 2016-03-22 12:25:04 +01:00
Victor Stinner c9553876ae Simplify implementation of hashtable.c 
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.

Victor Stinner 285cf0a601 hashtable.h now supports keys of any size 
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*).

Victor Stinner e0b75b7e87 Fix test_ssl.test_refcycle() 
Issue #26590: support.check_warnings() stores warnins, but ResourceWarning now

alive.

Victor Stinner 19a8e844e4 Add socket finalizer 
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).
