This hooks into the existing redirection framework but allows you
to quickly deny certain paths with a 403 or other status code.
The snippet below would for example declare a filemap served from 'www'
directory but denying all access to the files under the 'data' directory:
filemap / www
deny /data 403
Inside the domain contexts a 'redirect' rule will allow you to redirect
a request to another URI.
Ex:
Redirect all requests with a 301 to example.com
redirect ^/.*$ 301 https://example.com
Using capture groups
redirect ^/account/(.*)$ 301 https://example.com/account/$1
Adding the query string in the mix
redirect ^/(.*)$ 301 https://example.com/$1?$qs
These changes improve the constraint kore had with client authentication and
multiple domains.
- Add kore_x509_subject_name() which will return a C string containing
the x509 subject name in full (in utf8).
- Log TLS errors if client authentication was turned on, will help debug
issues with client authentication in the future.
- If SNI was present in the TLS handshake, check it against the host specified
in the HTTP request and send a 421 in case they mismatch.
- Throw a 403 if client authentication was enabled but no client certificate
was specified.
Before kore needed to be built with NOTLS=1 to be able to do non TLS
connections. This has been like this for years.
It is time to allow non TLS listeners without having to rebuild Kore.
This commit changes your configuration format and will break existing
applications their config.
Configurations now get listener {} contexts:
listen default {
bind 127.0.0.1 8888
}
The above will create a listener on 127.0.0.1, port 8888 that will serve
TLS (still the default).
If you want to turn off TLS on that listener, specify "tls no" in that
context.
Domains now need to be attached to a listener:
Eg:
domain * {
attach default
}
For the Python API this kills kore.bind(), and kore.bind_unix(). They are
replaced with:
kore.listen("name", ip=None, port=None, path=None, tls=True).
- Kore can now fully be configured via Python code if one wants nothing to
do with configuration files.
- Kore can now start single python files and no longer requires them to be
inside a module directory.
- Pass all regex capture groups to the handler methods, allowing you to
get access to them immediately.
- Change python websocket_handshake to take callable objects directly.
- Added a new deployment configuration option. If set to "dev" or
"development" Kore will automatically foreground, no chroot / etc.
If set to "production" Kore *will* chroot, drop privs, etc.
- Many more..
These are all backported from a project that I was working on a while
ago. I decided these should go back into mainline Kore.
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.
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.
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.
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.
This means you can now do things like:
resp = await koresock.recv(1024)
await koresock.send(resp)
directly from page handlers if they are defined as async.
Adds lots more to the python goo such as fatalx(), bind_unix(),
task_create() and socket_wrap().
Don't let net_recv_flush() do things as long as the HTTP layer
owns the buffer. When we have sent a response kick the read end
back into gear ourselves by calling net_recv_flush().
This is calculated while the HTTP body is incoming over the wire, once
the body is fully received the digest will be available for the page
handlers to obtain.
You can obtain a hex string for this md via http_body_digest() or
dereferences the http_request and look at http_body_digest manually
for the bytes.
