Changes:
uWSGI 2.0
Changelog [20131230] Important changes
Dynamic options have been definitely removed as well as the
broken_plugins directory Bugfixes and improvements
improved log rotation do not rely on unix signals to print
request status during harakiri added magic vars for uid and
gid various Lua fixes a tons of coverity-governed bugfixes made
by Riccardo Magliocchetti
New features --attach-daemon2
this is a keyval based option for configuring external daemons.
Updated docs are: :doc:`AttachingDaemons` Linux setns() support
One of the biggest improvements in uWSGI 1.9-2.0 has been the total
support for Linux namespaces.
This last patch adds support for the setns() syscall.
This syscall allows a process to "attach" to a running namespace.
uWSGI instances can exposes their namespaces file descriptors
(basically they are the files in /proc/self/ns) via a unix socket.
External instances connects to that unix socket and automatically
enters the mapped namespace.
to spawn an instance in "namespace server mode", you use the
--setns-socket <addr> option
uwsgi --setns-socket /var/run/ns.socket --unshare net,ipc,uts ...
to attach you simply use --setns <addr>
uwsgi --setns /var/run/ns.socket ...
Updated docs: :doc:`Namespaces` "private" hooks
When uWSGI runs your hooks, it verbosely print the whole hook action
line. This could be a security problem in some scenario (for example
when you run initial phases as root user but allows unprivileged
access to logs).
Prefixing your action with a '!' will suppress full logging:
[uwsgi] hook-asap = !exec:my_secret_command
Support for yajl library (JSON parser)
Til now uWSGI only supported jansson as the json parser required
for managing .js config files.
You can now use the yajl library (available in centos) as alternative
JSON parser (will be automatically detected) Perl spooler support
The perl/PSGI plugin can now be used as a spooler server:
uwsgi::spooler(sub {
my $args = shift; print Dumper($args); return -2; });
The client part is still missing as we need to fix some internal
api problem.
Expect it in 2.0.1 ;) Gateways can drop privileges
Gateways (like http router, sslrouter, rawrouter, forkptyrouter
...) can now drop privileges independently by the master.
Currently only the http/https/spdy router exposes the new option
(--http-uid/--http-gid) Subscriptions-governed SNI contexts
The subscription subsystem now supports 3 additional keys (you can
set them with the --subscribe2 option):
sni_key
sni_cert
sni_ca
all of the takes a path to the relevant ssl files.
uWSGI is a fast (pure C), self-healing, developer-friendly WSGI server,
aimed for professional python webapps deployment and development.
Backend support exists for Apache, nginx, cherokee and lighttpd.
Some of the features include:
- low memory footprint
- preforking and multithreaded operation
- logging, diagnostic and profiling support
- support for sendfile()
- self-healing
- graceful restart and hot-plug upgrading
