uWSGI 1.9.17

Changelog [20130917]

Bugfixes

  • the 'pty' client is now blocking (safer approach)
  • removed strtok() usage (substituted by a new uwsgi api function on top of strtok_r() )
  • fixed --pty-exec (Credits: C Anthony Risinger)
  • listen_queue/somaxconn linux check is now done even for UNIX sockets

New features

The Master FIFO

This is a new management way in addition to UNIX signals. As we have no more free signals to use (and generally dealing with signals and pidfiles is not very funny), all of the new management features of uWSGI will be based on the master fifo.

Docs are already available: :doc:`MasterFIFO`

The asap hook

Credits: Matthijs Kooijman

a new hook, named 'asap' has been added. It will be run soon after the options are parsed.

Check: :doc:`Hooks`

The TCC (libtcc) plugin

TCC is an embeddable c compilers. It includes a shared library (libtcc) you can use to compile strings of c code on the fly.

The libtcc uWSGI plugins allows compiling strings of c to process symbols. CUrrently the "tcc" hook engine has been implemented:

[uwsgi]
hook-asap = tcc:mkdir("/var/run/sockets");printf("directory created\n");
hook-as-user = tcc:printf("i am process with pid %d\n", getpid());
hook-post-app = tcc:if (getenv("DESTROY_THE_WORLD")) exit(1);
http-socket = /var/run/sockets/foobar.sock

The forkptyrouter gateway

While work on Linux containers/namespaces continues to improve we have added this special router/gateway allowing dynamic allocation of pseodoterminals in uWSGI instances. To access the sockets created by the forkptyrouter you can use the --pty-connect option exposed by the 'pty' plugin.

Documention is being worked on.

added a new magic var for ANSI escaping

The %[ magic var has been added, it allows you to define ANSI sequences in your logs.

If you like coloured logs:

log-encoder = format %[[33m${msgnl}%[[0m

Routable log encoders

You can now attach log encoders to specific log routes:

[uwsgi]
logger = stderr file:/dev/tty
log-route = stderr ubuntu
log-route = stderr clock
print = %[[34mHELLO%[[0m
; add an encoder to the 'stderr' logger
log-encoder = format:stderr %[[33m${msgnl}%[[0m
http-socket = :9090

--vassals-include

Credits: Matthijs Kooijman

This is like --vassal-inherit but the parsing will be "immediate" (so you can use placeholders)

The Emperor heartbeat system is now mercyless...

The old approach for the heartbeat Emperor subsystem was asking for "gentle" reload to bad vassals.

Now vassals not sending heartbeat (after being registered with the heartbeat subsystem) are killed with -9

The result of this patch will be more robust bad vassals management

logpipe

Author: INADA Naoki

You can now send loglines to the stdin of an external command:

req-logger = pipe:/usr/local/bin/mylogger

added "fd" logger to "logfile" plugin

you can directly send logs to a file descriptors:

req-logger = fd:17
