archivey 0.2.1

A patch release: no public name was added, renamed or removed.

Added

• 7z archives that use 7-Zip 24's RISC-V branch filter now read. The filter is decoded in Python, so it needs no extra package.
• archivey extract --dry-run prints a peak use of the reader limits: line: the largest decoder allocation, the temporary-file peak, the key-derivation rounds and the listing size, to compare with the limits before tightening them.
• Reading a member of a solid 7z or RAR archive with open() or read() logs one INFO record per reader when it decodes data an earlier call already decoded, and names stream_members() as the one-pass alternative.
• The docs state the versioning and stability policy: until 1.0, a removed or renamed name warns for one minor release before it goes.

Changed

• ExtractionPolicy.STANDARD refuses a path segment made only of dots or spaces (such as ... or .. ), as STRICT already did: Windows trims such a segment to .. or merges it away, so the name means something different there. STANDARD also treats notes. and notes as the same file, as Windows does, so the second one is a collision on every platform instead of silently replacing the first on Windows.
• A ZIP member compressed with Zstandard reads every frame, as a .zst file does. A second frame used to raise DataAfterEndError.
• The STREAM_REWIND_REDECOMPRESSES diagnostic is logged at INFO instead of WARNING. It is still collected and can still be escalated by a DiagnosticPolicy.
• When rapidgzip speeds up seeking, the members of one archive share its child process on Linux instead of starting one each, and the child reads a ZIP member from the archive file directly instead of through the parent process.

Fixed

• Several bugs: a zstd seek table pointing where the decoder cannot start no longer makes a seek fail, a rapidgzip member stream used after fork() raises ArchiveyUsageError instead of disturbing the parent's decoder, and a PPMd member refused under NATIVE_DECODERS isolation now names the setting that reads it.
