- create html output for interface stats
- create html output for link state routing stats
performs correctly, and can be genuinely used to test failover from
http to mdp.
this has been confirmed by running the resulting rhizomeprotocol test
before and after application of the fix for the regression that stopped
the failover from working in certain circumstances.
OUT()s or where return() is used instead of RETURN().
Added OUT() to end of all functions using IN() that lacked it to
make it easier to statically analyse this invariant.
Fixed several return instead of RETURNs detected through use of
this tool. #49
Add strn_startswith() and strncase_startswith().
Make all str*_startswith() functions take const char * arguments, to make it
possible to do safe programming with consts.
The "rhizome direct push" command (and also sync) was not waiting for the
server's HTTP response, so it was exiting before the server had finished
storing the bundle, which led to a race with the subsequent "assert
bundle_received_by" test. Fixed by adding the missing code to receive the HTTP
response.
Refactored the code used for parsing HTTP responses in rhizome_fetch.c, and
used it in rhizome_direct_http.c.
It turns out that if the DB is locked, sqlite_prepare_v2() call can return
SQLITE_BUSY. The retry logic (implemented for issue #2) only provided for
sqlite_step() to return SQLITE_BUSY. It was a fairly straightforward matter to
extend the retry logic to cover statement preparation in an equally general
fashion.
The problem was observed while diagnosing failures in the rhizomeprotocol
DirectPush test case: the "servald rhizome list" command was failing due to a
locked database. See issue #9.
Must be enabled by using rhizome.api.addfile.*
Certainly polishing to be done, including using filename supplied
during HTTP POST. Now to fix that, and make it all work with
final rhizomeprotocol test case.
rhizomeprotocol test cases 8 and 9 currently fail post-merge. #9
Handle failure cases properly. The HttpImport test now fails because the
"servald" executable is not found by the system(3) call -- need to give the
full path name, or avoid the use of system(3) altogether.
All test cases pass on Solaris (see issue #16) except the 'jni' tests because
there is no Java compiler available on Solaris, and the new 'rhizomeprotocol'
tests from the rhizomedirect branch, which have always failed.
iching calculator bug - unknown response codes not more than four
no longer result in "a suffusion of yellow".
Also stopped dropping HTTP requests on empty reads when parsing
a multi-part POST.
Closes#2.
Rewrite all Rhizome db query code using new retry primitives defined in
"rhizome.h": sqlite_step_retry(), sqlite_retry(), sqlite_retry_done(), etc.
Replace all calls to sqlite3_prepare_v2() with sqlite_prepare() which does
proper error logging.
Fix bug: re-invoking sqlite3_blob_close() on SQLITE_BUSY return causes process
to abort. Use an explicit BEGIN...COMMIT around the blob writing code instead.
Tested using repeated invocations of batphone/tests/meshms1.
Delete deprecated Rhizome db code in rhizome_crypto.c that has been replaced
with keyring file.
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.
Remove need to nul-terminate the received buffers in HTTP fetch reply handling
and HTTP server request parsing.
Remove redundant copying of data.
More rigorous parsing code, probably less vulnerable to overrun exploits.
Better debug logging of requests and responses.
Was not transmitting actual HTTP server port in rhizome announcements, was
always transmitting port 4110.
When trying for a free HTTP server port, sometimes bind() succeeds but listen()
fails with EADDRINUSE, so new logic to deal with that.
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
