Wire NCP 0x16/0x17 Extract a Base Handle and NCP 0x16/0x18 Restore an
Extracted Base Handle to connection-local directory-handle state.
The WebSDK documents NCP 0x2222/22/23 as taking a DirectoryHandle and
returning a 14-byte save buffer composed of a 10-byte ServerNetworkAddress
plus a 4-byte HandleID. The same documentation describes NCP 0x2222/22/24 as
taking that saved ServerNetworkAddress/HandleID pair and returning a
NewDirectoryHandle plus AccessRightsMask.
The SDK headers expose these calls as NWSaveDirectoryHandle() and
NWRestoreDirectoryHandle(), with the save buffer explicitly documented as 14
bytes. The Rust nwserver and lwared references do not implement this older
save/restore pair, and newer clients typically use the normal allocate/set
directory-handle calls instead, so keep the MARS-NWE HandleID opaque and
connection-local rather than guessing a global NetWare directory-base number.
Store extracted base-handle IDs in a small per-connection table that records
the saved volume/path tuple. Extract requires a live permanent directory
handle, and Restore validates the saved server address against this server
before allocating a new permanent directory handle for the saved path.
Add the SDK request/reply semantics to the inline endpoint comments and remove
the corresponding TODO entry.
This enables the documented endpoint path while keeping the saved HandleID
conservative and private to MARS-NWE.
Novell NCOPY can allocate temporary directory handles while checking
effective directory rights before copying. On long-running test runs the
temporary directory handle table may already contain stale entries, causing
Allocate Temporary Directory Handle to fail with -0x9d / "no directory
handles". NCOPY then falls back to relative GetEffectiveRights requests that
fail and reports:
NWGetEffectiveDirectoryRights returned an error.
Restore recycling of stale temporary directory handles in xinsert_new_dir().
Free slots are still preferred. If none are available and the caller requests
a temporary handle, recycle the oldest temporary handle for the same task first,
then the oldest temporary handle globally. Permanent directory handles are not
recycled.
This matches the expected NetWare-style behaviour for temporary handles and
allows NCOPY-style allocate-temp-handle / get-effective-rights flows to keep
working after repeated tests.
Apply the ignore-case volume option when preparing the SYS:LOGIN
directory path during connection setup.
With SYS configured as `itO`, the installed tree may use lowercase
Unix directories such as `login/`, but the connection code still tried
to stat the hard-coded uppercase `LOGIN/` path. This caused new client
connections to abort with:
Stat error LOGIN Directory, Abort !!: No such file or directory
UnixPath=`.../SYS/LOGIN/`
Treat `VOL_OPTION_IGNCASE` like `VOL_OPTION_DOWNSHIFT` for this path so
the login directory is resolved as `login/` on ignore-case volumes.
