Release ODFileSystem v0.5.0 · reinauer/ODFileSystem

Highlights

Native AmigaOS 4 support: adds a PPC/OS4 handler path with
FileSystemVectorPort, freestanding startup, Kickstart module support, and
OS4-specific DOS/vector semantics.
Workbench and filesystem behavior fixes: improves OS4 lock handling,
file handle state, directory examine behavior, media-change handling,
shutdown, and caller-task I/O so native OS4 callers behave correctly.
Much faster directory and parent lookups: adds cached ExNext resume
offsets, cached parent ancestors, incremental volume lock lists, and a faster
ACTION_PARENT path using .. entries where available.
Faster file reads and cache lookups: batches contiguous backend reads and
replaces linear block-cache scans with hashed lookups.
Release-ready packaging: adds separate OS3 and OS4 build, CI, release,
LHA, and Aminet upload paths, including separate Aminet readmes for each
target.

Added native AmigaOS 4 handler support with a per-target compatibility
layer, OS4 startup code, FileSystemVectorPort frontend, and OS4-specific
build paths.
Implemented OS4 vector callbacks for locks, file handles, reads, seeks,
metadata, directory examine, inhibit/serialize operations, and read-only
mutation handling.
Added freestanding OS4 handler startup so the filesystem can receive
ACTION_STARTUP directly, avoiding C runtime startup consuming the initial
DOS packet.
Added Kickstart module registration support for the OS4 CDFileSystem
path.
Fixed OS4 Workbench behavior by completing native vector semantics,
preserving file handle arguments, returning native SameLock/SameFile
results, and binding ExamineData to DOS-owned contexts.
Fixed OS4 caller-task reads by using caller-owned and cached I/O requests
instead of reusing the handler task request from vector callbacks.
Added OS4 media-change, shutdown, DOS list allocation, lock allocation,
and vector callback serialization fixes.

Batched contiguous file reads across ISO9660, Joliet, UDF, HFS, and HFS+
through a shared cache helper.
Reworked block-cache lookups from linear scans to hash-table lookups.
Added pooled allocation for duplicate-name fixing during directory scans.
Cached OS3 ExNext resume offsets to avoid rescanning large directories.
Cached parent ancestors on shared objects to speed repeated parent lookups.
Updated volume lock lists incrementally instead of rebuilding from all locks.
Sped up ACTION_PARENT by using .. directory entries where available,
improving AmigaOS 3.2 CD boot behavior.

Documented separate AmigaOS 3 and AmigaOS 4 build flows.
Added PPC AmigaOS 4 CI builds using the amigappc-gcc container.
Split release builds into OS3 and OS4 artifact builders.
Added OS4 release artifacts alongside the existing OS3 outputs.
Added OS3 and OS4 LHA package targets and separate Aminet readmes.
Added a release-published Aminet workflow that uploads both OS3 and OS4
packages from v* releases.
Raised the ROM profile size limit to match current generated handler size.

Split Amiga OS compatibility code out of the shared packet handler.
Removed scattered OS target conditionals from shared handler code.
Tightened Amiga build compiler selection so make amiga chooses the intended
cross-compiler while still honoring explicit overrides.
Routed OS4 serial debug logging through DebugPrintF().
Accepted OS4 ACTION_SHUTDOWN in the packet loop.
Fixed the OS4 media-change interrupt callback calling convention.
Allocated OS4 DOS list nodes and locks through DOS-supported APIs.
Kept OS4 legacy packets on the classic dispatcher while serializing access to
shared filesystem state.
Kept media state per handler process so multi-unit diskboot paths do not
overwrite each other.
Probed OS4 CD units before mounting to avoid publishing dead phantom units.
Shared node metadata formatting across packet and vector frontends.
Removed unused OS4 vector packet API surface and trivial compat wrappers.
