Replaced 'int has_author' manifest element with new 'enum authorship'
element to record the result of author authentication, to avoid
repeating expensive crypto operations.
Separated the handling of bundle secret arguments from author lookup and
authentication. The new rhizome_apply_bundle_secret(m,bsk) is now
called at the top level to set the manifest secret key (if it
validates), and thereafter there is no need to pass the 'bsk' argument
to any other functions, as they can simply check the 'haveSecret' field
of the manifest.
Removed rhizome_extract_privatekey() which combined author lookup and
bundle secret validation, and replaced it with functions that only deal
with the author: rhizome_lookup_author() and rhizome_authenticate_author().
Renamed other functions to make their purpose and effect clearer.
Formalised the semantics of only storing AUTHENTICATED author SIDs in
the 'author' column of the MANIFESTS table, which necessitated a change
to a 'rhizomeops' test case: when adding a file using a BK-less
manifest, the author column is set to null, so the Rhizome list output
does not show the bundle as ".fromhere" and does not give an author for
that bundle.
Replace generic rhizome_manifest_set() and rhizome_manifest_set_ll()
with per-field setter functions, eg, rhizome_manifest_set_filesize().
Struct rhizome_manifest elements for all known fields, to replace the
use of rhizome_manifest_get() and rhizome_manifest_get_ll() everywhere:
sender, recipient, service, name, date, bundle_key.
Add boolean validity flags for binary blob types, to avoid having to compare
with many bytes of all-zero to detect presence, eg, has_sender, has_recipient,
has_author, has_bundle_key. These maintained by the setter functions.
Rename existing manifest struct elements to be the same as their field
names: fileLength -> filesize, journalTail -> tail.
More use of unsigned int, size_t and uint64_t for payload sizes, offsets, byte
counts, etc. especially in rhizome_store.c and meshms.c. More uniform use of
size_t to dimension memory buffers. Fix some printf(3) style format strings
for 64-bit correctness on 32-bit systems. Use new constant RHIZOME_SIZE_UNSET
instead of -1 to indicate unknown dimension, and explicitly assert its absence
before comparisons and arithmetic, for safety.
Replace some 'int' loop variables with 'unsigned' where appropriate.
Fix bugs discovered in MeshMS bundle private/public key generation and
bundle secret key handling for export/extract commands.
Instrument the first MeshMS test case to aid debugging.
New debug config flag: debug.manifest logs all modifications to all manifest
fields by setter functions.
Rename debug config flag: debug.rhizome_bind -> debug.rhizome_sql_bind.
Use open(2)/read(2)/write(2) instead of fopen(3)/fread(3)/fwrite(3) in
several places to avoid unnecessary buffering
Fix a bug in Rhizome HTTP add's handling of unconfigured manifest
template file
Improve some debug and error logging for file i/o
Remove stowSid() at last
Change API of tohex() and strbuf_tohex(), to pass string length instead of
binary byte count. This allows odd numbers of hex digits to be produced.
Remove alloca_tohex_sid(); replace with alloca_tohex_sid_t()
New alloca_tohex_sid_t_trunc() macro
