The logic is no longer applicable due to how urllib3-future grows. + We no longer use the function ``wait_for_read``. Also we stopped using MSG_PEEK for our discrete incoming data watcher + due to suspicious behavior noticed. Finally we shielded any exception from attempting to close a broken socket. + 2.11.900 (2024-10-21) ===================== diff --git a/src/urllib3/_async/connection.py b/src/urllib3/_async/connection.py index 1d7f0386ef..56e8c819d9 100644 --- a/src/urllib3/_async/connection.py +++ b/src/urllib3/_async/connection.py @@ -281,7 +281,6 @@ def is_closed(self) -> bool: def is_connected(self) -> bool: if self.sock is None: return False - # wait_for_read: not functional with multiplexed connection! if self._promises or self._pending_responses: return True return self._protocol is not None and self._protocol.has_expired() is False diff --git a/src/urllib3/_version.py b/src/urllib3/_version.py index a1d69dcf08..2d6b4b4ab9 100644 --- a/src/urllib3/_version.py +++ b/src/urllib3/_version.py @@ -1,4 +1,4 @@ # This file is protected via CODEOWNERS from __future__ import annotations -__version__ = "2.11.900" +__version__ = "2.11.901" diff --git a/src/urllib3/backend/_async/hface.py b/src/urllib3/backend/_async/hface.py index fa8d801c16..1d6da87251 100644 --- a/src/urllib3/backend/_async/hface.py +++ b/src/urllib3/backend/_async/hface.py @@ -720,7 +720,6 @@ async def peek_and_react(self) -> bool: bck_timeout = self.sock.gettimeout() # either there is data ready for us, or there's nothing and we stop waiting # almost instantaneously. - # we can't use socket.MSG_PEEK in asyncio socket wrapper, it is non-functional. self.sock.settimeout(0.001) try: @@ -1597,7 +1596,10 @@ async def close(self) -> None: # type: ignore[override] ): # don't want our goodbye, never mind then! break - self.sock.close() + try: + self.sock.close() + except OSError: + pass self._protocol = None self._stream_id = None diff --git a/src/urllib3/backend/hface.py b/src/urllib3/backend/hface.py index 2186b9d7a7..a771a98f4e 100644 --- a/src/urllib3/backend/hface.py +++ b/src/urllib3/backend/hface.py @@ -768,39 +768,22 @@ def peek_and_react(self) -> bool: if self.sock is None or self._protocol is None: return False - try: - self.sock.setblocking(False) - except OSError: # disconnected! - return False + bck_timeout = self.sock.gettimeout() - # SSLSocket can't support non-zero flag for read. - # so, we'll improvise! - if isinstance(self.sock, ssl.SSLSocket): - try: - sock = socket.socket(fileno=self.sock.fileno()) - except (OSError, AttributeError): - # Defensive: that means we can't go further, sock is not standard or don't implement fileno - return False + self.sock.settimeout(0.001) - try: - peek_data = sock.recv(self.blocksize, socket.MSG_PEEK) - except OSError: - return False - finally: - self.sock.setblocking(True) - else: - try: - peek_data = self.sock.recv(self.blocksize, socket.MSG_PEEK) - except OSError: - return False - finally: - self.sock.setblocking(True) + try: + peek_data = self.sock.recv(self.blocksize) + except (OSError, TimeoutError, socket.timeout): + return False + finally: + self.sock.settimeout(bck_timeout) if not peek_data: return False try: - self._protocol.bytes_received(self.sock.recv(self.blocksize)) + self._protocol.bytes_received(peek_data) except self._protocol.exceptions(): return False @@ -1669,7 +1652,10 @@ def close(self) -> None: ): # don't want our goodbye, never mind then! break - self.sock.close() + try: + self.sock.close() + except OSError: + pass self._protocol = None self._stream_id = None diff --git a/src/urllib3/connection.py b/src/urllib3/connection.py index ad9dc9d1dd..57fee813b3 100644 --- a/src/urllib3/connection.py +++ b/src/urllib3/connection.py @@ -27,7 +27,6 @@ from .response import HTTPResponse from .util.timeout import _DEFAULT_TIMEOUT, Timeout from .util.util import to_str -from .util.wait import wait_for_read try: # Compiled with SSL?
