If built with PYTHON_CORO_DEBUG in CFLAGS Kore will spew out coroutine
traces while running. These traces include the filename, function and line
number where the coroutines are waking up, running and suspended.
- decouple pgsql from the HTTP request allowing it to be used in other
contexts as well (such as a task, etc).
- change names to dbsetup() and dbquery().
eg:
result = kore.dbquery("db", "select foo from bar")
Prevents a stall in case there is still data in the read end of the socket
but PQisBusy() told us to not fetch a result yet. In that case we end up
stalling due to epoll not giving us another EPOLLIN event due to EPOLLET.
In case libcurl instructs us to call the timeout function as soon
as possible (timeout == 0 in curl_timeout), don't try to be clever
with a timeout value of 10ms.
Instead call the timeout function once we get back in the worker
event loop. This makes things a lot snappier as we don't depend
on epoll/kqueue waiting for io for 10ms (which actually isn't 10ms...).
- If Kore is built with PYTHON=1 you can now specify the module that
should be loaded on the command-line.
eg: $ kore -frn myapp
- Add skeleton generation for python applications to kodev.
eg: $ kodev create -p myapp
This should make it a whole lot easier to get started with kore python.
1) Add @kore.prerequest python decorator.
Using this decorator on a function will cause that function
to always be executed *before* any page handler is run.
eg:
@kore.prerequest
def _check(req):
if req.method == kore.HTTP_METHOD_POST:
req.populate_post()
2) Allow attributes to be set on the pyhttp object.
If the connection on which we are about to send the response was
marked as disconnecting, do not go ahead and hook into the disconnect
callback (it will never be called, it is already disconnecting).
Instead just return, the connection will be removed anyway.
We grab a reference to the pyhttp_client for the client_op data structure
but never removed it. This caused the pyhttp_client object to never
be released when out of scope.
python_coro_create() puts the HTTP request to sleep, but if they
finish immediately they will be removed from the list and should
properly be woken up or they are removed from the wrong list.
Introduce kore_curl_strerror(), use this in kore_curl_logerror()
instead of assuming our errbuf has been populated.
Also use it in the python httpclient when throwing an exception rather
then looking at the errbuf member which may or may not be empty.
No need to wait until the next time http_process() is called, which
could result in HTTP requests backing up even though we are processing
them at a fast pace.
1) If a coroutine was waken up by another releasing a lock it was waiting
on we would incorrectly remove the pylock_op when the newly awoken coroutine
hits the iternext for pylock.
2) If a coroutine attempts to grab a lock it was woken up for only to fail
we did not properly rearm the coroutine to be woken up later to try again.
a commit done in 2018 prevented http responses with error codes
> 500 to include any user-set headers, preventing a developer
to include things like content-type etc.
reported by Arun Babu via users@
if an iterator is passed kore will send the response with
transfer-encoding: chunked and call the iterator for every
chunk that was sent.
The iterator must return a utf-8 string.
Works wonderful with TemplateStream from jinja2.
