bpo-40602: _Py_hashtable_set() reports rehash failure (GH-20077)

2020-05-14T20:44:32+00:00

If _Py_hashtable_set() fails to grow the hash table (rehash), it now
fails rather than ignoring the error.

bpo-40602: Write unit tests for _Py_hashtable_t (GH-20091)

2020-05-14T19:55:47+00:00

Cleanup also hashtable.c.
Rename _Py_hashtable_t members:

* Rename entries to nentries
* Rename num_buckets to nbuckets

Revert "bpo-32604: [_xxsubinterpreters] Propagate exceptions. (GH-19768)" (GH-20089)

2020-05-14T16:46:24+00:00

* Revert "bpo-40613: Remove compiler warning from _xxsubinterpretersmodule (GH-20069)"

This reverts commit fa0a66e62d087765dbc5c1b89d6149a23ecfb0a6.

* Revert "bpo-32604: [_xxsubinterpreters] Propagate exceptions. (GH-19768)"

This reverts commit a1d9e0accd33af1d8e90fc48b34c13d7b07dcf57.

bpo-40549: posixmodule.c uses defining_class (GH-20075)

2020-05-14T16:05:58+00:00

Pass PEP 573 defining_class to os.DirEntry methods. The module state
is now retrieve from defining_class rather than Py_TYPE(self), to
support subclasses (even if DirEntry doesn't support subclasses yet).

* Pass the module rather than defining_class to DirEntry_fetch_stat().
* Only get the module state once in _posix_clear(),
  _posix_traverse() and _posixmodule_exec().

bpo-40521: Add PyInterpreterState.unicode (GH-20081)

2020-05-13T23:48:38+00:00

Move PyInterpreterState.fs_codec into a new
PyInterpreterState.unicode structure.

Give a name to the fs_codec structure and use this structure in
unicodeobject.c.

bpo-40613: Remove compiler warning from _xxsubinterpretersmodule (GH-20069)

2020-05-13T13:38:27+00:00

bpo-40609: _Py_hashtable_t values become void* (GH-20065)

2020-05-13T02:40:30+00:00

_Py_hashtable_t values become regular "void *" pointers.

* Add _Py_hashtable_entry_t.data member
* Remove _Py_hashtable_t.data_size member
* Remove _Py_hashtable_t.get_func member. It is no longer needed
  to specialize _Py_hashtable_get() for a specific value size, since
  all entries now have the same size (void*).
* Remove the following macros:

  * _Py_HASHTABLE_GET()
  * _Py_HASHTABLE_SET()
  * _Py_HASHTABLE_SET_NODATA()
  * _Py_HASHTABLE_POP()

* Rename _Py_hashtable_pop() to _Py_hashtable_steal()
* _Py_hashtable_foreach() callback now gets key and value rather than
  entry.
* Remove _Py_hashtable_value_destroy_func type. value_destroy_func
  callback now only has a single parameter: data (void*).

bpo-40609: _tracemalloc allocates traces (GH-20064)

2020-05-13T01:52:11+00:00

Rewrite _tracemalloc to store "trace_t*" rather than directly
"trace_t" in traces hash tables. Traces are now allocated on the heap
memory, outside the hash table.

Add tracemalloc_copy_traces() and tracemalloc_copy_domains() helper
functions.

Remove _Py_hashtable_copy() function since there is no API to copy a
key or a value.

Remove also _Py_hashtable_delete() function which was commented.

bpo-40609: Add destroy functions to _Py_hashtable (GH-20062)

2020-05-13T00:50:18+00:00

Add key_destroy_func and value_destroy_func parameters to
_Py_hashtable_new_full().

marshal.c and _tracemalloc.c use these destroy functions.

bpo-40609: Remove _Py_hashtable_t.key_size (GH-20060)

2020-05-13T00:26:02+00:00

Rewrite _Py_hashtable_t type to always store the key as
a "const void *" pointer. Add an explicit "key" member to
_Py_hashtable_entry_t.

Remove _Py_hashtable_t.key_size member.

hash and compare functions drop their hash table parameter, and their
'key' parameter type becomes "const void *".
