deps(pip)(deps): bump the python-major group with 3 updates

[dependabot]

Bumps the python-major group with 3 updates: cryptography, portalocker and websockets.

Updates cryptography from 49.0.0 to 50.0.0

Changelog

Sourced from cryptography's changelog.

50.0.0 - 2026-07-31

* **SECURITY ISSUE**:
  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.pkcs7_decrypt_der`
  and its PEM and S/MIME variants no longer expose distinguishable errors or
  timing when unwrapping a ``RecipientInfo``'s ``encryptedKey``, which could
  act as a Bleichenbacher oracle for callers that decrypt untrusted messages.
  A random key is now substituted on failure, as described in :rfc:`3218`.
  Credit to **@X1AOxiang** for reporting the issue. **CVE-2026-69247**
* Deprecated Diffie-Hellman key exchange over finite fields (FFDH).
  Everything FFDH is deprecated, including the types in
  ``cryptography.hazmat.primitives.asymmetric.dh`` and loading FFDH keys or
  parameters with the key loading APIs. Users should migrate to a more
  modern key exchange algorithm.
* Added ``xof()`` class methods to
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE128` and
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE256` for constructing
  algorithm instances configured for use with
  :class:`~cryptography.hazmat.primitives.hashes.XOFHash`.
* The :mod:`X.509 verification <cryptography.x509.verification>` APIs are now
  considered stable and are subject to our API stability policy.
* Added the :doc:`/cobblestone` recipe, an implementation of the
  Cobblestone-128 and Cobblestone-256 instantiations of the `C2SP
  chunked-encryption specification
  <https://c2sp.org/chunked-encryption>`_ for streaming authenticated
  encryption of large messages.
* Parsing a Signed Certificate Timestamp list now rejects encodings that
  carry trailing bytes after the list or after an individual SCT, instead of
  silently ignoring them.
* Added support for using :class:`~cryptography.x509.Name` as a field type in
  the :doc:`/hazmat/asn1/index` module.
* Loading a public key or an EC private key now rejects DER where the
  ``subjectPublicKey`` (or EC ``publicKey``) ``BIT STRING`` declares a non-zero
  number of unused bits, instead of silently ignoring it.
* Parsing a CRL entry's ``InvalidityDate`` extension now rejects a
  ``GeneralizedTime`` that carries fractional seconds or another non-DER form,
  matching the strict encoding already required for every other X.509 time
  field.
* :func:`~cryptography.x509.ocsp.load_der_ocsp_request` and
  :func:`~cryptography.x509.ocsp.load_der_ocsp_response` now reject a request
  or response whose ``version`` field is not ``v1``, the only version defined
  by RFC 6960, matching the version validation already performed when loading
  certificates, CSRs and CRLs.
* :class:`~cryptography.hazmat.primitives.hashes.XOFHash` is now supported
  when building against AWS-LC.
* HMAC (and therefore PBKDF2-HMAC) with SHA-3 hashes is now supported when
  building against AWS-LC.
* Diffie-Hellman (:doc:`/hazmat/primitives/asymmetric/dh`) is now supported
  when building against AWS-LC.

Updates portalocker from 3.2.0 to 4.0.0

Release notes

Sourced from portalocker's releases.

v4.0.0

4.0.0:

• Fixed open_atomic() replacing a destination created while its context was open on POSIX; publication now raises FileExistsError and preserves the concurrent winner (#114)
• Python 3.10 or later is now required; Python 3.9 (EOL) support dropped
• pywin32 is no longer installed by default on Windows; the msvcrt-based locker is the default and works dependency-free for exclusive locks. Shared locks on Windows require portalocker[win32], and an informative ImportError is raised otherwise (#104)
• POSIX lock exceptions now populate .strerror and pass the message as a second positional argument, matching the Windows exception contract. This changes the str() output of these exceptions on POSIX from the bare OSError text to a 2-tuple repr
• LockBase is now generic over the acquire return type (typing-only change; downstream Lock subclasses are unaffected)
• Added PidFileLock for pidfile-based locking (#106)
• Added PidFileLock.fail_closed() for ownership-only contexts; contention raises AlreadyLocked before entering the body and exposes the competing PID through AlreadyLocked.holder_pid when readable (#118)
• Packaging switched to the uv_build backend; releases are published to PyPI through GitHub Actions Trusted Publishing
• python -m portalocker combine: --output-file now opens lazily; the vendored single-file output correctly includes RedisLock (it was always None before); the smoke-run now uses sys.executable (fixes Windows)
• Fixed PidFileLock ignoring timeout when fail_when_locked=False; all PID-publication failures now transactionally release the sidecar and preserve the publication error if cleanup also fails (#116)
• Fixed a TemporaryFileLock/PidFileLock unlock-then-unlink race that could let two processes hold the same lock (split-brain); release now unlinks before unlocking on POSIX and acquire re-verifies file identity (inode) after locking (#115)
• Fixed BoundedSemaphore staying permanently "Already locked" after a non-contention error (e.g. a missing directory)
• Fixed RedisLock crashed-holder detection: the liveness check was always satisfied by its own subscribe confirmation, so dead holders were never reaped; the ping is now published only after the subscription is confirmed active, pubsub connections no longer leak on the reap path, fail_when_locked=True fails fast instead of polling the full timeout, internally-created connections are closed on release, and a failed acquire() rolls back cleanly so the lock can be retried
• Added shared RedisLock readers through LockFlags.SHARED. Waiting writers gate new readers to prevent starvation, holder-specific heartbeats preserve stale-client cleanup, and legacy Redis lock responses are treated as exclusive for mixed-version safety (#124)
• Fixed FlockLocker/LockfLocker on POSIX to use their named syscall (previously silently used the global LOCKER); the module-level lock()/unlock() on POSIX now accept all documented LOCKER
