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.
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
Move lots of non-Serval-specific string functions from "serval.h"/dataformats.c
to "str.h"/str.c.
Add str_fromprint() function that reverses the effect of toprint(): interprets
escape sequences in the source string "\n\t\r\0\xHH\\" and replaces them with a
single char in the destination string.
- close database after every command line operation
- don't cache rhizome enabled configuration
- don't send advertisements unless the database is open and the web server is running
- don't provess advertisements unless the database is open
Replace the main-loop scheduled periodic alarm with an "activate" alarm that is
scheduled whenever a fetch candidate is added to any queue, unless the alarm is
already scheduled.
Replace the "rhizome.fetch_interval_ms" config item with
"rhizome.fetch_delay_ms" [default 50], which is the number of milliseconds
between adding a fetch candidate and firing the "activate" alarm. This allows
time for a few more Rhizome advertisment packets to arrive after the first one,
before deciding which fetches to start first.
Add new `is_scheduled()` alarm primitive.
as recommended a while back by Dan Bernstein as offering the fastest
implementation of the crypto_sign() primitives for ARM.
Indeed this implementation IS faster. See comparison below for a
Rock 500 handset (800MHz(?) ARM6, no NEON):
Original ref/ implementation on an R500 stock rom (non-rooted)::
mean signature generation time = 96.80ms
mean signature verification time = 272.20ms
ref10/ implementations on an R500 stock rom (non-rooted):
mean signature generation time = 4.00ms
mean signature verification time = 13.00ms
Approximately 20x speed up, just like that :)
Add test case for new feature of the "rhizome add" command: if the author SID
is not specified (empty arg) then it searches the keyring for the author.
Removed "authorSid" argument from several functions that also take a struct
rhizome_manifest * arg, since the author, if known, is now supplied in the
struct.
Improve return value handling and refactored some rhizome crypto code.
Replace ".selfsigned" column with ".author" and ".fromhere" columns in
output of "rhizome list" command. (Note that a "sender" column is
already present.)
Add 'author' field to struct rhizome_manifest.
Log all fully rendered SQL statements on DEBUG_RHIZOME.
Update 'rhizomeops' test cases and improve the assert_rhizome_list()
test function to be able to assert authorship of files.
signatures were not being recorded. Also fixed separate issue
where rhizomeprotocols tests expected selfsigned to be 1 on
receiver end, when it will never be, because the BK doesn't match.
rhizome direct push test in rhizomeprotocols now passes. #9
Objective is to avoid having to call system("servald rhizome import ...") to
handle a Rhizome direct POST /rhizome/bundle request. Antiquated code in and
around rhizome_import_bundle() needs much cleaning up, as indicated by some
TODO comments. Invocations must unnecessarily write the manifest into a file,
when they already have it in memory, ready to pass to the function.
All the 'rhizomeops' tests pass, but two 'rhizomeprotocol' tests are broken
by the changes in this commit.
Do not add 'filehash' var to manifest if filesize=0
Do not accept 'filehash' var when parsing manifest with filesize=0
When responding to a new rhizome advertisement, do not try to HTTP
request a payload if filesize=0, just import the manifest directly
Various operations, eg "rhizome file add", do not report 'filehash'
fields where 'filesize' is zero
Do not delete rows from MANIFESTS table which have empty filehash
Various related bug fixes
Tests assert that stderr contains no ERROR: lines after a successful exit
Rewrote sqlite_exec_int64() to separate error outcomes from legitimate
result values
Changed several WHY() calls to DEBUG()
Improved test framework
