similar to: Question about HUP + USR2 + QUIT

Hey guys, I''m sending USR2 to unicorn after cap deploy, and the old master is getting replaced by a new master that doesn''t work. Here are some similar threads I found ... http://rubyforge.org/pipermail/mongrel-unicorn/2010-October/000733.html http://rubyforge.org/pipermail/mongrel-unicorn/2010-October/000717.html I''m not using Bundler, and I have working_directory

Hi, I have a question about automating the restarting of Unicorn with the following steps, and much appreciate your help. Assumption: (i) "pid" is set to unicorn.pid in the config file; (ii) a Unicorn process is already running. (1) kill -USR2 `cat unicorn.pid` (via Capistrano deployment task for example) (2) Inside the "before_exec" hook in the config file, do: kill -QUIT

I cannot find any good example of a unicorn upstart task that works properly for the following: * Upstart will restart if unicorn dies * Can send USR2 signal to unicorn to do a no downtime deploys * Able to stop upstart job, even after a deploy I have tried the following: expect fork respawn setuid www-data chdir /var/www/app/current exec bundle exec unicorn_rails -E production -c

Signaling using normal kill(2) is preserved, but the master now prefers to signal workers using a pipe rather than kill(2). Non-graceful signals (:TERM/:KILL) are still sent using kill(2), as they ask for immediate shutdown. This change is necessary to avoid triggering the ubf (unblocking function) for rb_thread_call_without_gvl (and similar) functions extensions. Most notably, this fixes

I would love to see a timestamp in each line of unicorn stderr and stdout logs. Has this been considered? Thanks. Best, alex sharp

Hi - I tried to get Daemontools and Unicorn working together a while back - there are issues on USR2 restart because of the pid change - I''m hoping someone in the community will have some understanding of this issue I documented my experience and eventual defeat here : http://log.robotarmyma.de/post/2053448029/daemontools-ubuntu-rvm-bundler-unicorn-install Any help would be received

Hi, A couple days ago, I was trying to run Unicorn for Ramaze, and found that `Unicorn.run'' didn''t share the same interface with other Rack handlers, i.e. `options[:Host]'' and `options[:Port]'' Because of this, I can''t just use: Rack::Handler.register(''unicorn'', ''Unicorn'') And invoke this:

Hello all, I''m wondering if you deploy nginx: 1) on the same machine that runs unicorn (exclusively proxying to that) 2) on a different machine that doesn''t run unicorn 3) both, nginx could forward to either to localhost or another host on the same LAN And of course, the reason(s) you chose what you chose. I''m inclined to believe many folks are on 1) simply

First off thanks very much for all the hard work on unicorn. Alas, we''ve encountered an issue where unicorn fails to spawn new workers that have loaded the incoming revision on a capistrano deploy. I''m not entirely sure the issue is due to unicorn as it appears that bundler was responsible for a similar issue in the past:

Hello, I''m using unicorn since a while, but now I try to run it the first time inside a FreeBSD jail. The initial start of unicorn works fine and it serves all the requests. But if I want to restart it using the USR2 signal, it (more or less) slowly starts using more and more CPU cycles. There is no error message in the logs and it quite hard to reproduce that error. In 1 of 20 tries,

Hi, Unicorn is saying it''s terminating but it''s not actually.

?Hi, I was wondering if anyone has managed to get the preload_app and SIGUSR2 combination working well with upstart? My issue currently is that when I perform a SIGUSR2 against the master, check everything''s working and close off the old master, upstart then attempts to restart it because the original PID/binary are no longer running. What is the correct way of handling this? In my

Sorry if this is the wrong place to ask, but when I run mongrel evented using swiftiply and then send it the USR2 signal to restart it, it dies. Without eventing, USR2 restarts mongrel as expected. Anyone else seen this? Here''s a dump: $ EVENT=1 mongrel_rails start -d -P /tmp/m.pid -p 4321 Using Evented Mongrel ** Ruby version is up-to-date; cgi_multipart_eof_fix was not loaded $ kill

Hi folks, I''ve experimented a problem while deploying my app, I''ve sent the HUP signal to the master process, I''ve checked everything is ok: new master and workers are spawned and the old ones are killed(I''ve checked the PIDs), but the new code deployed isn''t reflected in the living site, so I''ve to stop and start again unicorn in order to see

We have a service that clients use to upload files. We have a couple of clients that are on slow links and so their upload times out. We get errors in the logs that I''d like to get rid of. I was hoping that the recent commit 24b9f66dcdda44378b4053645333ce9ce336b413 would help us, but it does not. After digging in a bit, I have some ideas about why and a patch I''d like comments

Hi, I''m wondering why SIGINT and SIGTERM both were chosen for the quick shutdown? I agree with SIGINT but not with SIGTERM. A lot of unix tools send SIGTERM as default (kill, runit among some) and it seems to be the standard way of telling a process to quit gracefully but not among Ruby people (there are a few other ruby processes behaving the same way). I just think it''s weird

If unicorn doesn''t get terminated cleanly (for example if the machine has its power interrupted) and the pid in the pidfile gets used by another process, the current unicorn code will exit and not start a server. This tiny patch fixes that behaviour. --- lib/unicorn/http_server.rb | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/lib/unicorn/http_server.rb
