Add a NULL guard to protocol_release_memory_for_session so it no-ops like
the sibling session setters. Correct the Data.owner doc comment, which
implied a non-zero protocol_charge always has an owner; document that
owner may be NULL for uncharged/ownerless Data, that any such charge
falls back to the bound session, and that a charged Data must not outlive
its owning session. Note the lifetime contract on the release API too.
Extend tests/test_protocol.c to cover destroying a charged Data with no
session bound (the other half of the original bug) and to assert that
data_create/data_create_reserve start with owner == NULL and
protocol_charge == 0.
Data charged against a ProtocolSession kept only the charge amount, so
data_destroy released it from whatever session was thread-locally bound
at destroy time. Destroying a received Data on another thread, after the
session was unbound, or while a different session was bound leaked the
originating session's budget and underflowed the other's.
Add Data.owner, set it whenever protocol_receive_data_limited charges a
session, and have data_destroy release against that owner directly via
the newly-exported protocol_release_memory_for_session. Uncharged Data
(owner NULL) keeps the previous bound-session fallback.
Add a unit test proving a Data acquired on session A is released to A
even when unrelated session B is bound at destroy time.
- Fix transport_tcp.c: initialize server->ssl_ctx to NULL
(prevents SSL_CTX_free on garbage when server_create_tls fails)
- Fix test_transport_tcp.c: client_create now sets fd=-1, family=AF_UNSPEC
- Fix test_transport_tcp.c: server address family may be AF_INET or AF_INET6
- Fix test_file_sendfile.c: send_path=false protocol includes file_type prefix
- Reformat all C/H files to match .clang-format (LLVM style)
- Fix 26 cppcheck const-correctness warnings (constParameterPointer,
constVariablePointer, constVariable)
- Update function declarations in headers to match const parameters
- Remove FileReceive struct; use File everywhere with nullable FileMetadata*
- Remove struct stat from File; file size lives in Data->size (data_create_reserve)
- Add FileMetadata struct (mode, uid, gid, mtime) sent conditionally over wire
- Add -M / --preserve flag to client
- Restore permissions, ownership, timestamps on disk write
- Wire format uses per-file present flag for metadata (zero overhead when off)
