This commit introduces the ability to add authenticators to filemaps.
Just like in normal routes, the authenticators will be resolved first
before allowing access to the filemap entries.
Configuration wise, the authenticator is an optional value after the
filemap config directive:
filemap / webroot myauth
In the Python API you can now pass the authenticator for a filemap entry
but turning the value of the filemap into a tuple with the first entry
being the path and the second being the auth dict:
AUTH AUTH={
"type": "cookie",
"value": "cookiename",
"redirect": "/auth/",
"verify": verify_cookie
}
domain.filemaps({
"/css/": "webroot/css",
"/secret/": ("webroot/secret", AUTH)
})
The parent process never differentiated between a worker process
asking for a shutdown or a worker process calling fatalx() when
it came to its exit code.
I made some changes here so the parent process will exit with
an exit code 1 if anything worker related went wrong (fatalx/death policy).
The coroutines results are now relayed back via PyIter_Send() and
no longer obtainable via _PyGen_FetchStopIterationValue().
This means that our kore.gather() would not be able to return any
values from any of the coroutines it governed.
Fix this by saving the object returned in PyIter_Send() and using it
later in pygather_reap_coro().
Python 3.10.x its PyIter_Send() will return PYGEN_ERROR if the
generator returned (as opposed to yielding) if the result returned
is Py_None and no argument was given to PyIter_Send(). Which is counter
intuitive since it seems it should give us a PYGEN_RETURN as per its
documentation.
It also no longer sets PyExc_StopIteration in this case so we cannot depend
on that anymore to figure out if a coroutine has finished.
This caused Kore to respond with a 500 immediately after coroutines
ran to completion as it was looking for the PyExc_StopIteration exception.
Fix this by simply doing another check if an exception happened before
we enter the code path where Kore would spew the 500.
The cmsghdr contains a length (cmsg_len) which indicates the length
of the data in combination with the cmsghdr length itself.
Remove the length of the cmsghdr before passing it back up to callers
so they don't need to bother with it.
This also fixes a mistake where we ended up copying extra data
from the ancdata buffer that was unintended.
When this code was moved from src/connection.c into src/tls_openssl.c
a return wouldn't break us out from kore_connection_handle() as
previously expected.
This ment that Kore would move the connection into established state
immediately even if SSL_accept() needed to read more.
This broke TLS client authentication as Kore its belts and suspenders
kept throwing a 403 due to the code not properly obtaining the client
certificate when expected.
The whole while (cnt-- >= 0) idiom is busted since cnt started
at 0 and if the first call to PyUnicode_FromStringAndSize() fails
then we're attempting to access -1.
