Takes a new parameter now `qs`, if set to 1 it'll urldecode
according to how its always done it before.
If not set to 0 (for posts for example), the decoder will allow
\n and \r in addition to the other ones.
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)
})
Routes are now configured in a context per route:
route /path {
handler handler_name
methods get post head
validate qs:get id v_id
}
All route related configurations are per-route, allowing multiple
routes for the same path (for different methods).
The param context is removed and merged into the route context now
so that you use the validate keyword to specify what needs validating.
Starting with the privsep config, this commit changes the following:
- Removes the root, runas, keymgr_root, keymgr_runas, acme_root and
acme_runas configuration options.
Instead these are now configured via a privsep configuration context:
privsep worker {
root /tmp
runas nobody
}
This is also configurable via Python using the new kore.privsep() method:
kore.privsep("worker", root="/tmp", runas="nobody", skip=["chroot"])
Tied into this we also better handle worker startup:
- Per worker process, wait until it signalled it is ready.
- If a worker fails at startup, display its last log lines more clearly.
- Don't start acme process if no domain requires acme.
- Remove each process its individual startup log message in favour
of a generalized one that displays its PID, root and user.
- At startup, log the kore version and built-ins in a nicer way.
- The worker processes now check things they need to start running
before signaling they are ready (such as access to CA certs for
TLS client authentication).
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).
This commit introduces the ability for the keymgr process
to reload the certificates/keys for domains when receiving
a SIGUSR1 signal.
The keymgr receives 2 new configuration options:
- keymgr_root_path
The root path where the keymgr will live.
If -n is not specified when the application starts the
keymgr process will chroot into here.
- keymgr_runas_user
The user the keymgr will drop privileges towards if
-r was not specified.
All certfile and certkey configuration options are now relative to the
keymgr_root_path configuration setting.
The keymgr process will now also load the certificate for the domain
(rather then the workers) and submit these to the worker processes so
they can be reloaded when required.
Worker processes will refuse connections until the TLS configuration
for a given domain is completed (aka: the workers receive the certificate
for that domain).
Other changes:
- client_certificates renamed to client_verify.
- the chroot configuration option is now called root.
- kore is a little more verbose if privsep options are missing.
- filemaps are now relative to the root configuration option.
- make sure we can serve updated files even if we have an old
fileref around.
- add filemap_index as a configuration option: allows one to specify
what file to serve if a directory was requested (eg: index.html)
A filemap is a way of telling Kore to serve files from a directory
much like a traditional webserver can do.
Kore filemaps only handles files. Kore does not generate directory
indexes or deal with non-regular files.
The way files are sent to a client differs a bit per platform and
build options:
default:
- mmap() backed file transfer due to TLS.
NOTLS=1
- sendfile() under FreeBSD, macOS and Linux.
- mmap() backed file for OpenBSD.
The opened file descriptors/mmap'd regions are cached and reused when
appropriate. If a file is no longer in use it will be closed and evicted
from the cache after 30 seconds.
New API's are available allowing developers to use these facilities via:
void net_send_fileref(struct connection *, struct kore_fileref *);
void http_response_fileref(struct http_request *, struct kore_fileref *);
Kore will attempt to match media types based on file extensions. A few
default types are built-in. Others can be added via the new "http_media_type"
configuration directive.
