- Add kore_pgsql_query_param_fields() which allows you to pass in the
arrays for values, lengths and formats yourself.
- Add kore_pgsql_column_binary() which will return 1 if the given column
index contains a binary result or 0 if it contains a text result.
- Change the query call in req.pgsql() for Python to always use the
parameterized queries.
This adds the 'params' and 'binary' keywords to the req.pgsql method.
Eg:
result = await req.pgsql("db", "INSERT INTO foo (field) VALUES($1"),
params=["this is my value"])
This commit adds the CURL=1 build option. When enabled allows
you to schedule CURL easy handles onto the Kore event loop.
It also adds an easy to use HTTP client API that abstracts away the
settings required from libcurl to make HTTP requests.
Tied together with HTTP request state machines this means you can
write fully asynchronous HTTP client requests in an easy way.
Additionally this exposes that API to the Python code as well
allowing you do to things like:
client = kore.httpclient("https://kore.io")
status, body = await client.get()
Introduces 2 configuration options:
- curl_recv_max
Max incoming bytes for a response.
- curl_timeout
Timeout in seconds before a transfer is cancelled.
This API also allows you to take the CURL easy handle and send emails
with it, run FTP, etc. All asynchronously.
By default kore will restart worker processes if they terminate
unexpected. However in certain scenarios you may want to bring down
an entire kore instance if a worker process fails.
By setting worker_death_policy to "terminate" the Kore server will
completely stop if a worker exits unexpected.
this change also stops python coroutines from waking up very
late after their timeout has expired.
in filerefs, don't prime the timer until we actually have something
to expire, and kill the timer when the last ref drops.
Attach the events directly to the pysocket data structure instead of
one event per pysocket_op.
Makes the code easier, gives us a good performance boost and reduces
the number of system calls required when doing an await on a socket.
if a crl is expired or not-yet-valid SSL_get_verify_result()
will return these errors too so check for them explicitly
instead of depending on X509_V_OK.

With these changes CRLs can be reloaded like certificates
by sending a SIGUSR1 to the parent process.
Track mtime on both certificate files and CRL files as well
and only submit them to the workers if this has changed.
Move away from the parent constantly hitting the disk for every
accesslog the workers are sending.
The workers will now write their own accesslogs to shared
memory before the parent will pick those up. The parent
will flush them to disk once every second or if they grow
larger then 1MB.
This removes the heavy penalty for having access logs
turned on when you are dealing with a large volume
of requests.
- add kore.time() as equivalent for kore_time_ms().
- call waitpid() until no more children are available for reaping otherwise
we risk missing a process if several die at the same time and only one
SIGCHLD is delivered to us.
- drain a RECV socket operation if eof is set but no exception was given.
Before we just doubled in size the second we exhausted a pool instead
of doing a more controlled expansion.
Now we will expand at 25% of the initial elm count whenever we need to.
Will help with memory pressure in certain scenarios.
Allows one to run coroutines concurrently and gather all their
results in a single returned list.
If any of the coroutines throw an exception the exception is
returned as the value of that coroutine in the returned list.
This commit removes TLS 1.0 support no matter what OpenSSL
you are linking against.
Changes the value of tls_version from 1.2 to both. Meaning if
you link with OpenSSL 1.1.1 you will get 1.2 + 1.3.
This adds kore.proc to the python runtime allowing async processing
handling:
The kore.proc method takes the command to run and an optional timeout
parameter in milliseconds. If the process did not exit normally after
that amount of time a TimeoutError exception is raised.
For instance:
async def run(cmd):
proc = kore.proc(cmd, 1000)
try:
await proc.send("hello")
proc.close_stdin()
except TimeoutError:
proc.kill()
retcode = await proc.reap()
return retcode
If exists these functions are called when the worker is exiting
and when right before the parent exists.
Allows for cleanup code for applications if need to do cleanup on exit.
