The issue #20681 describe the error of delete() function
removing the elements from the origin array/hash/string.
This issue affected other delete functions. Because
ruby delete and delete_if functions make destructive
changes to the origin array/hash.
The delete_undef_values removed elements from the
origin array/hash and this is not the desired behaviour.
To solve this, we should dup or clone the array/hash
before using the delete or delete_if ruby functions.
We should also check if args[0] is not nil before using
dup, since dup on nil raises exception.
This fix the problem and add unit tests, so we could
enforce this behaviour and prevent regressions.

The setup: list with 3 elements, delete one:
$test_list = [‘a’, ‘b’, ‘c’]
$test_deleted = delete($test_list, ‘a’)
Print out the elements in ‘test_deleted’:
notify { ‘group_output2’: withpath => true, name => “$cfeng::test_deleted”, }
Notice: /Stage[main]/Syslog/Notify[group_output2]/message: bc
Good! Run-on output shows that ‘a’ was deleted
Print out the elements in ‘test_list’:
notify { ‘group_output1’: withpath => true, name => “$cfeng::test_list”, }
Notice: /Stage[main]/Syslog/Notify[group_output1]/message: bc
WHAT!? 'a' was deleted from ‘test_list’ as well! Expected abc as output!
This behaviour is confirmed for string, hash and array.
This is fixed on this commit, I had added two spec tests to cover that cases.
bug #20681 spec test for delete() function.
I had forgot in the last commit the spec test for hash in the
delete function.
bug # 20681 delete() function change aproach.
Instead of rejecting elements from the original list, we use
collection = arguments[0].dup .
then latter we could continue to use delete and gsub! on collection
without impact on original argument.
this is a better solution than the previous one, and works on ruby
1.8.7, 1.9.3 and 2.0.0.
The previous solution does not work on ruby 1.8.7.
delete function remove typo whitespace.
fix typo whitespaces.
When pick function fail return a better error message like
the other stdlib functions, indicating that the error
is on function pick.
This would help people that see the error to identity it is
related to a incorrect use of stdlib function pick, instead of having
to grep all puppet libraries and manifests source for the old message.
I had also changed the spec test.
pick function change spec as suggested GH-179
Fix the spec test to use expect {}.to instead of lambda {}.should
as explained by Adrienthebo.
"Using expect { }.to is preferred over lambda { }.should.
In addition it's best practice to do a string match against the
error message to ensure that we're catching the right error,
instead of any error of the right type."
Also fixed a typo on the error message, it was missing one space.
pick function stylish fix as suggested on GH179
During a puppet run an error will be thrown and a puppet run will fail completely (when using validate_slength):
undefined local variable or method `arg' for #<Puppet::Parser::Scope:0x7f243c236948>
An optional third parameter can be given a min length. The function
then only passes successfully, if all strings are in the range
min_length <= string <= max_length
update and fix function and unit tests
the check for the minlength has to be written differently
because 0 values should be possible. We now check
a) if the input is convertible, and throw a ParseError and
b) if the input .is_a?(Numeric) and ask for a positive number
it's not as clean as for maxlength, but keeps a similar behaviour
refined the error checking for the min length
try to convert to Integer(args[2]) and fail,
if it's not possible
changed the tests accordingly to the new parameter checking
This patch allows an array of resource titles to be passed into
the ensure_resource function. Each item in the array will be
checked for existence and will be created if it doesn't already
exist.
This change is to implement a new function "any2array", which will take any
argument or arguments and create an array which contains it. If the argument
is a single array then it will be returned as-is. If the argument is a single
hash then it will be converted into an array. Otherwise (if there are more than
one argument, or the only argument is not an array or a hash) the function will
return an array containing all the arguments.
This is a bit more heavy-handed than I might like, but it does appear to
do the right things:
* accepts numeric input appropriately, truncating floats
* matches string input against a regex, then coerces number-looking
strings to int
* makes a best effort to coerce anything else to a string, then subjects
it to the same treatment
* raises an error in the event of incorrect number of arguments or
non-number-looking strings
I've also included some additional unit tests.
No more coercing to String and regex matching. Instead, we now coerce
to Integer at the beginning or raise an error if we cannot coerce to
Integer.
A consequence of this change is that the function will now accept
blatantly non-numeric strings as input, and return false. This seems a
bit goofy to me, but it's how String#to_i works. If we really don't
like this, then I'm open to suggestions.
Puppet passes numbers as String to functions, but it makes more sense to
compare them as Numeric.
But sometimes Puppet passes them as the wrong type, see:
https://projects.puppetlabs.com/issues/19812
When prefix and suffix did error checking with positional arguments,
they would not report the position of the argument that failed to
validate. This commit changes the messages to indicate which argument
failed.
