Generalize the error message for missing SSH agent support

software@the13thletter.info (Marco Ricci) — Sat, 02 Aug 2025 09:06:07 +0200

We retire the error message for missing UNIX domain socket support, in favor of a more general error message indicating that this Python and/or this `derivepassphrase` installation lacks certain functionality. We further delegate the UNIX domain socket-specific message to a warning message. We also introduce a warning message specific to Windows named pipes. (Both warning messages are prepared, but not yet in actual use.) Unfortunately, this entails changing the symbol name for the error message, because it would otherwise be misleading.

Comment on coverage exclusions, in shorthand

software@the13thletter.info (Marco Ricci) — Sat, 26 Jul 2025 17:35:21 +0200

Add shorthand codes for different types of coverage exclusions, explained in `pyproject.toml` in the `tool.coverage` section, because reasons for excluding code branches from coverage tend to fall into a handful of common categories. Also add explicit coverage exclusion patterns for dummy classes which are never intended to actually be called, such as the `_types._Omitted` class (for styling function signatures in the generated documentation) and the two `_DummyModule` classes (which stub out missing dependencies to appease the type checker). A very few coverage exclusions were actually unnecessary or nonsensical, and have been rectified.

Provide more deterministic signatures for the test keys

software@the13thletter.info (Marco Ricci) — Sat, 26 Jul 2025 16:45:41 +0200

Record and provide more deterministic signatures for the test keys, where feasible. In particular, for DSA and ECDSA keys, support recording the RFC 6979 deterministic DSA signatures, as implemented by Pageant. In particular, this entails that the `expected_signature` and `derived_passphrase` fields of the test keys need to change to accomodate the new shape of the data. For the existing DSA and ECDSA keys, RFC 6979 signatures and expected master passphrases are also provided. Providing the Pageant 0.68–0.80 deterministic signatures and expected master passphrases however is not quite so straight-forward: because the signature class is the subject of CVE-2024-31497, Pageant < 0.81 is considered to have a security hole, and thus it is hard to obtain pre-compiled, unpatched installations of Pageant to compute the signatures/master passphrases against.

Fix, and test for, the consistency of the SSH test keys

software@the13thletter.info (Marco Ricci) — Sat, 26 Jul 2025 11:45:19 +0200

A typo existed in the ECDSA NIST P-521 raw public key data, making it incompatible with the copy of the public key included in the raw private key blob. This caused UNIX Pageant (and likely any other SSH agent supporting deterministic DSA signatures, if they exist) to reject unloading and signing with that key, despite actually supporting the key format. So fix the typo, and add tests and machinery to ensure rudimentary consistency of all test key data.

Fix some test suite setup mistakes

software@the13thletter.info (Marco Ricci) — Wed, 23 Jul 2025 20:13:06 +0200

These mistakes were carried over from v0.5, and cause woe on The Annoying OS even before actually running any tests.
