Rufus scheduler without passenger

[aavinash.behera]

Hello,

I am trying to use Rufus-Scheduler in my rails app in Azure.

I am using Ruby(1.9.3) & Rails(3.2.8) & Thin server in my rails app.

Is it necessary to use Phusion Passenger ?

Will rufus scheduler not work without it?

I am not able to start the scheduler. What am I doing wrong?

My code - 

require 'rubygems'

require 'rufus/scheduler'

scheduler = Rufus::Scheduler.start_new

scheduler.cron '00 9 * * *' do

     UserMailer.daily_message_report("some email").deliver

  end

Thanks, 

Avinash

No, not at all.

What makes you think so?

Rufus-scheduler is a ruby library. It has nothing to do with Passenger. It's
meant to work on any decent Ruby implementation.

Try to add this line:

---8<---
scheduler.join
--->8---

at the end of your script, so that it doesn't exit.

If that doesn't work, please say so and explain a bit further.

In local it is working fine.

It automatically generated 3 files :-

.rufus-scheduler.rb.swn

.rufus-scheduler.rb.swo

.rufus-scheduler.rb.swp

Even in local I am starting in production(rails s -e production) mode, its working.

Only when i do "rails s -e production -d" it stops working.

& in Azure server I have deployed my rails app. It didnt generate those 3 files as above.

I have done the same things what I did in local. I dont know why its not working even in production mode.

In some pages while googling that i have read, some are suggesting to use phusion passenger to make it work.

Hello,

are you trying to tell me that in local you are not using Passenger but you
do in production ?

John

[aavinash.behera]

No, I am not using passenger.

The problem is - In local, scheduler is working fine. Only not working when I start in daemon mode.

I am not able to make it work in Azure server. The scheduler is not being invoked here. 

Do I need to do any configuration in Azure server for Rufus-scheduler?

OK.

Sorry, I don't know anything about Azure server.

Could you please read https://gist.github.com/jmettraux/310fed75f568fd731814

Then please give me details about your production environment.

I cannot tell you now because you are not telling me what server you use in
production (and perhaps I cannot tell you).

If you could give me the link that says "rufus-scheduler works better with
Passenger"... I'd love to read that piece.

So, what are you using?

Ubuntu 12.10 - Same in local & in production.

Thin (1.5.1 codename Straight Razor) - Same in local & in production.

Rails 3.2.8 - Same in local & in production.

Ruby ruby 1.9.3p194(2012-04-20 revision 35410) [i686-linux] in local & ruby 1.9.3p448 (2013-06-27 revision 41675) in production

Sorry. In azure we created an instance where we are deploying our app there.

 

Could you please read https://gist.github.com/jmettraux/310fed75f568fd731814

Then please give me details about your production environment.

Sorry for this. They were previously using passenger so they have written for passenger.

So the article is not saying that rufus-scheduler works better on Passenger.

Great.


OK.

So this is your code:

```ruby

require 'rubygems'
require 'rufus/scheduler'
scheduler = Rufus::Scheduler.start_new

scheduler.cron '00 9 * * *' do
UserMailer.daily_message_report("some email").deliver
end

```

By the way, where do you put it?

...

Could you please try with?

```ruby

require 'rubygems'
require 'rufus/scheduler'
scheduler = Rufus::Scheduler.start_new

puts "0 - I'm in the schedule file..."

begin
UserMailer.daily_message_report("test email!").deliver
rescue => e
puts "vvv"
puts "cannot deliver mail"
puts
p e
puts e.message
puts
puts e.backtrace
puts "^^^"
end

scheduler.every '1m' do
puts "1 - rufus-scheduler is scheduling..."
end

scheduler.cron '00 9 * * *' do

begin
UserMailer.daily_message_report("some email").deliver
rescue => e
puts "vvv"
puts "something went wrong"
puts
p e
puts e.message
puts
puts e.backtrace
puts "^^^"
end
end
```

I wonder if the message 0 and the message 1 do appear in your console or in
your Rails log.

I wonder if your emails can be delivered...


Waiting for your feedback,

[aavinash.behera]

In local it worked for me.

I started the server in my production, it gave me this message - "0 - I'm in the schedule file...". I got the mail also.

After every minute I got this message - "1 - rufus-scheduler is scheduling..."

But it didnt go inside the cron. I didnt receive any mail after.

What is the issue ?

That cron means run "every day at 09:00 (am)". When is that for your
development machine? When is that for your production machine? Are they set
for the same time zone?

Do you test by waiting until it's 09:00 am or do you test by setting the next
hour/minute ?

What does

```ruby
scheduler.cron '* * * * *' do
puts "in..., it's #{Time.now} (#{Time.to_f})"

begin
UserMailer.daily_message_report("some email").deliver
rescue => e
puts "vvv"
puts "something went wrong"
puts
p e
puts e.message
puts
puts e.backtrace
puts "^^^"
end
end
```

do ?


Thanks in advance,

[avinash behera]

I have changed it manually in scheduler file.

In local it is fine.

Could not test in production either due to our client test the app this time.

Generally Production is in UTC timing. 

So, If i start in rails s -e production, it takes local time in production.

Time.to_f ? it was giving problem in local. (undefined method `to_f' for Time:Class)

 

Do you test by waiting until it's 09:00 am or do you test by setting the next
hour/minute ?

What does

```ruby
scheduler.cron '* * * * *' do
  puts "in..., it's #{Time.now} (#{Time.to_f})"

  begin
    UserMailer.daily_message_report("some email").deliver
  rescue => e
    puts "vvv"
    puts "something went wrong"
    puts
    p e
    puts e.message
    puts
    puts e.backtrace
    puts "^^^"
  end
end
```

do ?

OK.

I guess that by "local" you mean "developement environment".

OK, I guess you'll tell me another time.

Ah OK.

Sorry about that. I hope you could fix that detail by yourself.


I have the impression that your problem is solved.


Best regards,

[avinash behera]

Not yet, Its fine in development(local). But not in production. I am getting the starting mail, but not the one inside scheduler.cron in production.

Any changes need to do in production?

Hello,

before thinking about changes in production, could you please indicate me if
the puts "xyz" I have added to the your schedule code get printed.

Thanks for the feedback about the "starting" email, but as you can read, I
added a bunch of puts and I'd like to know if they output...

I would appreciate detailed feedback. Until now your feedback is very vague,
rather unprofessional. Please behave.


Thanks in advance,

[aavinash.behera]

Hello,

While starting the production server, I am getting this put :-

0 - I'm in the schedule file... & I am getting the email.

& after every 1 m I am getting this put:-

1 - rufus-scheduler is scheduling...

But it is not going inside scheduler.cron '* * * * *'.

All these in production thin server.

Thanks,

Avinash

Sorry for this.

Hello,

now, please add

```ruby
require 'pp'
def scheduler.on_exception(job, ex)
puts "*** intercepted exception"
pp job
puts
p ex
puts ex.message
puts
puts ex.backtrace
end
```

Right after the scheduler is initialized.

Does it output anything?

[aavinash.behera]

Hello,

Now in production, every one minute - puts "1 - rufus-scheduler is scheduling..." appears in console.

& I got the mail with scheduler.cron '* * * * *'

It seems to be working in production also now. 

Is there anything what I can do in daemon mode?

I tried starting in daemon mode - rails s -e production -d in production. It doesn't send me any mail.

Ah, thanks for that very important bit of information.

Try replacing my "puts" with Rails logging statements and then look at what
gets into the Rails logs.


Good luck,
