Hi,

[...]

 It is in the split in fact I don't have space between the value but 
 carried returns, so if I split to \n, it works. 


This is slightly worrisome.  I encourage you to go with separating values 
with a comma, not only because it follows style of how other facts return 
values, but also ensures that things will not break by accident (something 
may happen now and/or in the future).  As far as having single space there 
to separate results is also acceptable, then having \n there might not be 
what you want.  I do encourage you to strip surplus new lines and join 
values on single comma :)

My 2p, I hope you don't mind :)

[Puppet Users] Re: puppet calling stat() on managed symlinks

I forgot to add ...

You probably do not want Puppet to follow symbolic links which in 
conjunction with the recurse = true is leading to open() done on each 
new directory during traversal. Perhaps setting links = ignore will 
help, not sure, thought.

Re: [Puppet Users] stdlib/range issue

2012-03-29 Thread Krzysztof Wilczynski

Hi,

irb(main):008:0 (08..12).to_a

 = [08, 09, 10, 11, 12]

 irb(main):010:0 (8..12).to_a
 = [8, 9, 10, 11, 12]

 But then, the range() function in stdlib, makes a type conversion, that 
 breaks this possibility. I don't understand why do you do that 
 conversion... the function is just an interface to the range capability 
 of Ruby, right? I think it should allow the programmer to choose the type 
 he wants.


With great power comes great responsibility -- said that, please allow 
yourself to understand the following example:

(abc01..abc99 ).to_a

Observe this little (which may happen) mistake after abc99. That is the 
easily over-looked single space.

If you do that in your manifest, let say ... by accident... then your 
Puppet Master will more likely become a happy candidate for OOM Killer to 
consider :)

Do you know if, after editing a .rb file, I have to force some kind of 
 reload to pick up the changes?


No, there is no need to reload, but this is not the solution. Instead, in 
order to guarantee safe execution and also provide desired effect a 
different approach can be taken: You can scan for how many string-encoded 
digits you can fine within start of the range, count then and then based on 
this counter collect (or map if you like Perl so much) generated range with 
relevant substitution. If done right, then it will allow you to 
zero-padding of any size at any place in the string e.g. test00, 00test 
this00test, etc ...

I will update my version f range shortly to do precisely that.

Re: [Puppet Users] Re: dsl check if port is open

2012-03-28 Thread Krzysztof Wilczynski

Hi David,

No problem, although there are few things to consider. For instance, I 
would avoid unneeded fork(), therefore no need to use netcat if you can 
achieve the same thing with pure Ruby (you can literally copy and paste 
code from the function I have created for you). Remember, that in terms of 
having a fact there, you have to maintain details about the remote port in 
the fact code, whereas in case of the functions you simply store this 
information inside a manifest. But, to be quite honest, if you have to 
resort to such active checks in order to determine state of your systems 
and therefore make an elaborated decision in the code about what to do, 
then I would say that you are doing something not necessary right. Well, in 
the end whatever works as Woody Allen would say :)

 Managing firewall using Puppet as well, as per what Jeff suggested, is 
 of course the preferred way to solve this sort of problem, but if you need 
 to check whether a port is open, then have a look: 
 https://github.com/kwilczynski/puppet-functions/blob/master/lib/puppet/parser/functions/is_port_open.rb

 Jeff will probably not approve of that :-)


 Eh, I may surprise you...  I don't think my approval matters much at all 
 and I'm a fan of whatever works for the problem at hand given the tools we 
 have today.

 I can totally see the value of a function that automatically figures out 
 if a remote port is _actually_ open and listening, rather than _should_ be 
 open and listening, from the perspective of the Puppet master.

 With that said, I'm more interested in the problem David is facing than I 
 am in a specific solution solution because I'm pretty sure Puppet doesn't 
 have the capability to solve this in a elegant, simple and easy way.  We 
 can solve it with a custom function or custom fact today, but I'd like to 
 make this easier for everyone in the future.

 Some of my facts collect/parse a bunch of data and can be time consuming.

[Puppet Users] Re: dsl check if port is open

Ho David,

Managing firewall using Puppet as well, as per what Jeff suggested, is of 
course the preferred way to solve this sort of problem, but if you need to 
check whether a port is open, then have a look: 
https://github.com/kwilczynski/puppet-functions/blob/master/lib/puppet/parser/functions/is_port_open.rb

Jeff will probably not approve of that :-)

[Puppet Users] Re: virtual resources vs fqdn_rand

2012-03-22 Thread Krzysztof Wilczynski

Hi,

[...] 

 I have worked around this by passing in a $minute argument, but this
 seems a bit inelegant -- the slave certainly has no business
 determining the backup schedule.  Other than a feature request for
 fqdn_rand to allow a value to be passed in, any ideas on a more
 elegant way to accomplish this?  Criticism welcome!

I did this quickly for you: https://gist.github.com/2159360

kwilczynski@lamhirh ~/Sandbox $ RUBYLIB=. cat - | puppet 2 /dev/null
notice random_crontab_minutes('rsync', $hostname)
notice random_crontab_minutes('abc', 'def')
notice: Scope(Class[main]): 10
notice: Scope(Class[main]): 6
notice: Finished catalog run in 0.03 seconds

I am not sure if this will help / fit you use case, have a look :)

Re: [Puppet Users] custom fact issue

There is also no need to call date from within the shell saving on

I would imagine, that adding code to either ignore SIGCHLD, or collect

[Puppet Users] Re: Casting Fixnum to String (Hiera/YAML)

2012-03-01 Thread Krzysztof Wilczynski

Hi Lars,

[...]
It would be nice for a plain Integer (Fixnum) to work as well when
it's coming from a YAML file.

When you introduce a numeric value through the manifest, then Puppet
will do the right thing during parsing it, but when you introduce
Integer or Float from Hiera, then you will get them as-is after
parsing YAML, meaning as intended types in Ruby, so to speak. And
because Ruby is dynamic and uses duck-typing, it simply just work
internally to the point when parser is trying to combine both types.

I guess the question boils down to: Is there a way to cast from Fixnum
to String?

Yes, look below :)

It seems like an inconsistency to me that in Puppet it works quoted
and unquoted but not in YAML so I'd like to provide the same syntax
for both versions. For now i've added a validate_string($port) call.

Puppet in most cases treats non-negative Internet and Float as string
(unless this behavior differs nowadays).

Take a look on this:

https://github.com/kwilczynski/puppet-functions/blob/master/lib/puppet/parser/functions/num2str.rb

And this:

https://github.com/kwilczynski/puppet-functions/blob/master/lib/puppet/parser/functions/type.rb

I hope it helps a little :)

[Puppet Users] Re: Display correctly any array

Hi Steve,

 This is because puppet lacks the join() function, the obvious (but absent) 
 partner to the split() function.

By default yes, it does. But you can mitigate this problem with
puppetlabs-stdlib[1] and/or tackle this one:

https://github.com/kwilczynski/puppet-functions/blob/master/lib/puppet/parser/functions/join.rb

and probably this one might also come in handy:

[Puppet Users] Re: Display correctly any array

Hi Felix,

 Seeing as this has not been mentioned in the thread yet, I'm compelled
 to add:

 $array_to_str = inline_template(%= array * ', ' %)

 or even

 notify { my-notify:
   message = inline_template(Here is the %= array * ', ' %.);

 }

Ah, the oldie but goodie inline_template() abuse :-)

We should stop endorsing this, really, hehe :)
