Servald starts DNA helper, receives startup ACK, sends requests, receives
responses, handles malformed helper responses, echoes dnahelper stderr lines to
log, sends MDP reply packet, waits for dead helper process, all asynchronously.
Shuts down helper process during servald shutdown.
Remaining issues:
- Does not impose a timeout on helper responses.
- Only the first URI is reported by the "dna lookup" command.
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
Rhizome manifest parser now parses and validates all known fields, informs
about unsupported fields, and unpacks fields into relevant struct manifest
elements where appropriate. Is also stricter about whitespace.
Rhizome fetch code now logs debug messages if DEBUG_RHIZOME_RX bit is on.
that is called only when needed, and marks a manifest as finalised
if the verifcation fails. reading a manifest now never sets
finalised flag, as either _finalise() or _verify() must be called.
Move rhizome_new_manifest() out of rhizome_read_manifest_file() so that the
out-of-manifest report shows the names of the functions where the manifests
were really allocated.
Replace with WHY() or WHYF() everywhere
Improve logMessage() to handle file/line/function printing internally
Mainly so that log messages from manifest alloc/free in rhizome_bundle.c
can make it into the Android log
The sequence start time was only getting set in overlay_interface_init(), which
was not always called, or was called after overlay_gettime_ms() had already
been used.
Added FATALF(), FATAL() and FATAL_perror() macros.
Removed a bunch of debug statements no longer needed in monitor.c and server.c.
- If a bundle has the same payload hash and manifest.name as one already in
the rhizome store, then the "dna rhizome add" command will not add it
- Now passes fourth test case in tests/dna_rhizome
Now successfully fetches manifests for files we already have in
the database, using the existing database copy of the file.
Also added filter to stop same file being fetched more than once at
same time..
