Re: free vs. paid heroku app performance
That's what we do, setting up site monitoring is part of my normal routine so I have something checking the site every 5 mins including staging.

Re: free vs. paid heroku app performance
Thanks for the helpful tips about keeping the app responsive. Has anyone else encountered ridiculously long slug compilation (several hours), or is it just me? Its happened on at least 4 days in the past month. I checked the heroku status page each time, but only one of the times coincided with an official heroku problem. The production app was unaffected except for the official outage. I wonder if paying for a dyno would help reduce this problem too? -- You received this message because you are subscribed to the Google Groups "Heroku" group.

Running custom executables in your app
Hello
I'd just like to share this with you guys, maybe it will come in handy
for somebody someday.
I have a rake task for importing data from an external source. The
data includes geographic information that need to be converted using
the proj command-line utility (http://trac.osgeo.org/proj/). I opened
a support ticket to have Heroku install this, which is a standard
package in most Linux distros. For some unspecified reason they were
not able to do this, but instead asked me to try and include a
pre-compiled binary for the AMD64 platform in a bin/ directory of my
app.
So I randomly selected the latest Ubuntu distro, and got the
libproj0_4.7.0-1_amd64.deb and proj-bin_4.7.0-1_amd64.deb from there.
These can be unpacked with tar xzvf , and somewhere inside the
executables and the libraries can be found. I copied the 'proj'
executable and the 'libproj.so.0' library to a new bin/ directory of
my app, checked them into git, and pushed to Heroku.
After a bit of experimenting in the console, this is how I got the
program to run:
`LD_LIBRARY_PATH=$LD_LIBRARY_PATH:#{ENV['APP_ROOT']}/bin
#{ENV['APP_ROOT']}/bin/proj 2>&1`
This includes the bin/ dir in the LD_LIBRARY_PATH environment
variable, so that the proj executable is able to find the libproj.so.0
library file. The '2>&1' part just combines STDOUT and STDERR, so that
I'm able to see the output.
parvati:some-app martin$ heroku console
Ruby console for some-app.heroku.com
>> `LD_LIBRARY_PATH=$LD_LIBRARY_PATH:#{ENV['APP_ROOT']}/bin
>> #{ENV['APP_ROOT']}/bin/proj 2>&1`
=> "Rel. 4.7.1, 23 September 2009\nusage: proj [ -beEfiIlormsStTvVwW
[args] ] [ +opts[=arg] ] [ files ]\n"
>>
I love it when stuff works. Happy hacking!

Re: Using resque-scheduler
You should be able to fork, but you wouldn't want multiple schedulers so you'll be limited to 1 worker. You can setup another app that is another environment of your production app that only runs the scheduler. If you get resque:scheduler to run let me know. I've run it on heroku and it keeps getting killed for some reason then restarted, and it'd go down sometimes for 20 minuites. -Jon On Aug 26, 1:46 pm, Idris wrote: > We're trying to use resque-scheduler with Heroku, but resque-scheduler > requires two processes to be running, corresponding to the tasks > resque:scheduler (which schedules jobs), and resque:work (which pops > jobs off the queue and performs the work).

Re: Heroku Console and Gems
Not necessarily. .gems is deprecated IIRC, and only tells Heroku what to install. Your Rails app has to define gems in config/environment.rb w/ config.gem directives. Alternatively, switch to Bundler + Gemfile, and manage gems in one place.

Re: Heroku Console and Gems
David, Thanks, I'll take a look at using Bundler. For those of you wondering, I'm still trying to get migrations to work from Sequel. I've grabbed a bit of code from sequel for migrations, put it into my rakefile, but it's still not working. It looks like the require 'sequel' doesn't happen (or at least that's my impression from doing the same thing in the heroku console).

[ANN] new crashed process handling
We've just rolled out a new version of our process manager, with streamlined handling of crashed processes. A lot of you guys have been frustrated when your workers crash (libXML segfaults, for example) because the restart behavior was somewhat unpredictable. The new version follows a very simple algorithm: any process that crashes will be restarted immediately, with a cooldown time of ten minutes. This applies to all process types including web processes (dynos). We've also unified the behavior of crashed dynos with crashed workers. Now if you push up a bad deploy (missing a gem, etc) you won't be shown the stack trace in the browser, and instead can find the stack trace and debugging info by running "heroku logs". This makes the workflow for handling a crashed process the same as handling an exception during the request cycle (HTTP 500): your users are displayed a generic page, and you the developer can look up the problem in your logs. A description of the new crash policy, and some documentation for the "heroku ps" command (great for introspecting on the state of your processes) can be found here: http://docs.heroku.com/ps We welcome your feedback. Please reply (here on the mailing list, or to me privately) if you have any thoughts, especially if you've seen it in action on your own crashed processes. -- You received this message because you are subscribed to the Google Groups "Heroku" group.
