gh-132886: use relaxed atomics for `sock_fd` in gil builds in socket module (#133208) 2025-05-08 22:33:41 +05:30
Serhiy Storchaka 4c914e7a36
gh-133583: Add support for fixed size unsigned integers in argument parsing (GH-133584) 
* Add Argument Clinic converters: uint8, uint16, uint32, uint64.
* Add private C API: _PyLong_UInt8_Converter(),
  _PyLong_UInt16_Converter(), _PyLong_UInt32_Converter(),
  _PyLong_UInt64_Converter().

gh-132987: Support __index__() in the socket module (GH-133093) 
ntohl(), htonl(), if_indextoname(), getaddrinfo() now use __index__() if
available.

Also fix the Argument Clinic names for module-level functions (although
this does not affect the user).

gh-132099: Accept an integer as the address for BTPROTO_HCI on Linux (GH-132525) 
Previously only an integer packed in a tuple was accepted, while
getsockname() could return a raw integer.
Now the result of getsockname() is always acceptable as an address.

gh-70145: Add support for channels in Bluetooth HCI protocol (GH-132481) 2025-04-14 20:09:16 +03:00

gh-132099: Harmonize Bluetooth address handling (GH-132486) 
Now all protocols always accept the Bluetooth address as string and
getsockname() always returns the Bluetooth address as string.

* BTPROTO_SCO now accepts not only bytes, but str.
* BTPROTO_SCO now checks address for embedded null.
* On *BSD, BTPROTO_HCI now accepts str instead of bytes.
* On FreeBSD, getsockname() for BTPROTO_HCI now returns str instead of bytes.
* On NetBSD and DragonFly BDS, BTPROTO_HCI now checks address for embedded null.

gh-132429: Fix support of Bluetooth sockets on NetBSD and DragonFly BSD (GH-132431)

* Return cid in getsockname() for BTPROTO_L2CAP if it is not zero.
* Fix a compiler warning on FreeBSD.

gh-132075: Fix possible use of sockaddr structures with uninitialized members (GH-132076) 
Now all structure members are initialized with zeroes by default.

Victor Stinner 8cd29c2b53
gh-111178: Fix getsockaddrarg() undefined behavior (#131668) 
Don't pass direct references to sockaddr members since their type may
not match PyArg_ParseTuple() types. Instead, use temporary 'int' and
'unsigned char' variables, and update sockaddr members afterwards.

On FreeBSD, treat BTPROTO_HCI node name as a bytes string,
not as an integer.

gh-129288: Add optional l2_cid and l2_bdaddr_type in BTPROTO_L2CAP socket address tuple (#129293) 
Add two optional, traling elements in the AF_BLUETOOTH socket address tuple:

- l2_cid, to allow e.g raw LE ATT connections
- l2_bdaddr_type. To be able to connect L2CAP sockets to Bluetooth LE devices,
  the l2_bdaddr_type must be set to BDADDR_LE_PUBLIC or BDADDR_LE_RANDOM.

available. Replace "fall through" comments with _Py_FALLTHROUGH.

Add _Py__has_attribute() macro. No longer define __has_attribute()
macro if it's not defined. Move also _Py__has_builtin() at the top
of pyport.h.

Fix ThreadedVSOCKSocketStreamTest: if get_cid() returns the host

(loopback): VMADDR_CID_LOCAL.

On Linux 6.9, apparently, the /dev/vsock device is now available but

Brett Simmers c2627d6eea
gh-116322: Add Py_mod_gil module slot (#116882) 
This PR adds the ability to enable the GIL if it was disabled at
interpreter startup, and modifies the multi-phase module initialization
path to enable the GIL when loading a module, unless that module's spec
includes a slot indicating it can run safely without the GIL.

PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went
with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148.

A warning will be issued up to once per interpreter for the first
GIL-using module that is loaded. If `-v` is given, a shorter message
will be printed to stderr every time a GIL-using module is loaded
(including the first one that issues a warning).
