not to return some interfaces

We need to use
unless value.is_a?(String) || value.is_a?(Array)
rather than
klass = value.class
unless [String, Array].include?(klass)
because the klass version enforces type checking which is too strict, and does
not allow us to accept objects wich have extended String (or Array).
For example, generate() function now returns Puppet::Util::Execution::ProcessOutput
which is just a very simple extension of String. While this in it's self was
not intentional (PUP-2306) it is not unreasonable to cope with objects which
extend Strings

(MODULES-905) Narrow the confinement in bool2str
|
|
Previously, bool2str() accepted a broad array of boolean values and
bare strings, without any attempt to validate that the strings in any
way resembled "true" or "false" (or any of the other values bool2num()
accepts). This commit narrows the input confinement to TrueClass and
FalseClass, which means that bool2str() will only interpolate
strict boolean values now.
|
|
(MODULES-905) Add bool2str() and camelcase() for string manipulation
|
|
Python likes to have its constants Capitalized, and the capitalize
function only understands strings... so I shave a yak.
bool2str will convert a boolean to its equivalent string value,
and camelcase extends on uppercase & downcase to convert an underscore
delimited string into a camelcased string.

Allow concat to take non-array second parameters
|
|
Without this patch one can not specify package resource specific
parameters. All the ensure_packages() function does it makes sure
the named packages are installed. This patch allows one to pass
default as a second argument and allow greater flexibility on
packages installations.
Use case like the following are now possible :
* ensure_packages(['r10k', 'serverspec'], {'provider' => 'gem'})
* ensure_packages(['ntp'], {'require' => 'Exec[foobar]'})
|
|
Also improve and extend concat tests to lock down functionality
|
|
Instead of modifying the first paramater of deep_merge due to the
use of the merge! function, instead use merge to return a copy of
the merged object. This allows one to continue to use the original
first parameter after the call to deep_merge.
|
|
|
|
This version of pick() does not error out, instead always returning at least
the last argument, even if that too has no "real" value.
|
|
The documentation contained references to future decisions about
functionality.
Text rephrased for clarity.

I expect a function called "is_numeric" or "is_integer" to check if a
variable is an integer or a number even if the variable passed by isn't
a string nor a number at all. Otherwise we should call them
is_string_a_number and is_string_an_integer and we have then to remove
the check for .is_a?(Number) and .is_a?(FixNum)
now checking also if it is a hex or octal number
improved/corrected checking for integer
* checking against Integer instead of Fixnum so that
also Bignum is matching
* now .is_a? Integer is done first so this is quiet fast
Now many types of numerics are recognized.
1. Float/Integer values (signed or unsigned, with exponent or without)
2. octal and hex check
3. except hex numbers and the "0." in a float lower than 1 can be prefixed
with a '0'.
whitespaces shouldn't be allowed as prefix/suffix
string representation of numbers should not contain any type of
whitespace.. the user is responsible to clean a string before checking
it..
fix documentation and added more checks
tried to be 99.9% backward compatible
* for now the decission is post poned if hex and octal numbers
should be allowed or not (is_numeric)
* native Bignum is now also a valid integer class
fix problem with old 1.8 ruby and Hash.to_s/Array.to_s
In ruby < 1.9 array and hashes would be recognized as numeric
if they have a special format:
1.8:
[1,2,3,4].to_s = "1234"
{1=>2}.to_s = "12"
1.9:
[1,2,3,4].to_s = "[1, 2, 3, 4]"
{1=>2}.to_s = "{1=>2}"

Issue #20200 notes that the merge function does not
support nested hashes.
To prevent unintended side effects with changing merge,
add a deep_merge function instead.

Update pick error message "at least one non empty value"

This closes GH-180

Right now validation seems to be done against zero byte generated temp
files. We need to close the file before executing validation against it.

delete_undef_values function fix bug #20681
|
|
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>
