You can reproduce the error with a simple manifest
Bogus_type <| title == 'foo' |>
We used to fail because find_resource_type returned nil and we never
checked if it was nil before calling methods on it.

The following manifest was crashing puppetdoc:
class test {
include "test::$operatingsystem"
}
Because the quoted string is "rendered" as a concat AST, which in turn
ended being an array when entering RDoc.

When the responsibility for type-name resolution was moved to the AST nodes in
commit 449315a2c705df2396852462a1d1e14774b9f117, at least one instance was
missed: the space ship operator
Myclass <<| tag == foo |>>
fails unless Myclass has been previously loaded. This commit adds the lookup
to AST::Collection nodes in the same way it was added to the other node types.
Note that I haven't audited the other note types for similar cases.

|

My code smell routines bobbled this one, so I'm fixing it manually.

Accesing an array with an integer index (ie $array[1]) is producing
a ruby error: can't convert String into Integer
This is because the array index is not properly converted to an number
before the array element lookup is performed.

This is a reconciliation/melding of Paul's
(#4534) Class inheritance with parameterized classes is no longer ignored
and Markus's
Fix for #4778 -- evaluate parameterized classes when they are instantiated
Extracted the code from Resource::Type#mk_plain_resource that evaluates
parents and tags the catalog, and moved that into a new method called
instantiate_resource. Instantiate_resource is now also called from
Parser::Ast::Resource#evaluate, so that the notation
"class { classname: }"
now executes this code too. Likewise adds class evaluation so that it behaves
the same (with regard to lazy / strict evaluation) as
include classname

This is another case where our test objects were overly mocked so they
didn't alert us to problems with our implementation.

The :undef symbol, which we use internally to distinguish between
undefined variables and variables whose value is the empty string, is
being leaked in calls to functions (e.g. "split"). This is a
departure from 0.25.x behavior, where undefined variables evaluated to
"".
This patch restores the 0.25.x behavior.

We found the gsub! in extlookup was actually modifying the value for
extlookup_precedence, so the next node to call it just got the
interpolated value from the first run.
We did two things in the code to prevent this:
1. We returned a dup of the ast string object so that modifying it
wouldn’t change puppet’s state. We didn’t do this for all possible
return values because we depend on using the original ast array object
to do array concatenation
2. We fixed extlookup to not do a destructive gsub

My earlier #4397 patch was not aware of the parameterized class
instantiation syntax, and failed on manifests that instantiate
parameterized classes.

AST resources.
Move type-name resolution out of Puppet::Resource into the AST resources.
Move find_resource_type out of Puppet::Resource into Scope
Thus, never pass unqualified type names to Puppet::Resource objects.
Thus, Puppet::Resource objects don't need the namespace property,
and Puppet::Resource objects never consult the harddrive to look for
.pp files that might contain their type definitions,
Thus, performance is improved.
Also removes the temporary fix for #4257 that caused #4397
(The code was too eager to look for a class in the topscope)

This fixes double-quoted strings to interpolate undef variables
as an empty string. This is the behavior present in 0.25.x.

Ticket #4238 introduced a problem that a function couldn't compare to
another value until after it was evaluated, and AST::Function didn't have the
evaluate_match method. This change moves that method from AST::Leaf to AST.
The special casing necessary for doing comparisons between AST objects
feels messy and could probably be encapsulated better. I've created
ticket #4291 to remind us to refactor this at some point.

The comparisons operator (and more particularly == and !=) were not treating
the undef value as '', like case and selector did since #2818.
This patch makes sure comparison operator uses AST leaf matching.
Unfortunately, doing this introduces a behavior change compared to
the previous versions:
Numbers embedded in strings will now be matched as numbers in case and
selector statements instead of string matching.

This operator allows to find if the left operand is in the right one.
The left operand must be resort to a string, but the right operand can be:
* a string
* an array
* a hash (the search is done on the keys)
This syntax can be used in any place where an expression is supported.
Syntax:
$eatme = 'eat'
if $eatme in ['ate', 'eat'] {
...
}
$value = 'beat generation'
if 'eat' in $value {
notice("on the road")
}

The previous code maintained thread safety up to work-duplication (so that a
collision would, at worse, result in effective cache flushing and cause some
additional work to be done). The preceding patch addressed the single thread
issue of environment specific functions; this patch brings the thread safety
up to the previous standard.

Jesse and I are shooting for the minimal viable fix here, with the idea that
a great deal of refactoring is needed but isn't appropriate at this time. The
changes in this commit are:
* Index the function-holding modules by environment
* We need to know the "current environment" when we're defining a function so
we can attach it to the proper module, and this information isn't dynamically
available when user-defined functions are being created (we're being called by
user written code that doesn't "know" about environments) so we cheat and
stash the value in Puppet::Node::Environment
* since we must do this anyway, it turns out to be cleaner & safer to do the
same when we are evaluating a functon. This is the main change from the prior
version of this patch.
* Add a special *root* environment for the built in functions, and extend all
scopes with it.
* Index the function characteristics (name, type, docstring, etc.) by environment
* Make the autoloader environment aware, so that it uses the modulepath for the
specified environment rather than the default
* Turn off caching of the modulepath since it potentially changes for each node
* Tweak tests that weren't environment aware
|
|
|
|
|
|
| |
* Remove require statements
* explicity define namespace modules/classes for
Puppet::Resource::Status to avoid require dependency cycle.

You can now specify relationships directly in the language:
File[/foo] -> Service[bar]
Specifies a normal dependency while:
File[/foo] ~> Service[bar]
Specifies a subscription.
You can also do relationship chaining, specifying multiple
relationships on a single line:
File[/foo] -> Package[baz] -> Service[bar]
Note that while it's confusing, you don't have to have all
of the arrows be the same direction:
File[/foo] -> Service[bar] <~ Package[baz]
This can provide some succinctness at the cost of readability.
You can also specify full resources, rather than just
resource refs:
file { "/foo": ensure => present } -> package { bar: ensure => installed }
But wait! There's more! You can also specify a subscription on either side
of the relationship marker:
yumrepo { foo: .... }
package { bar: provider => yum, ... }
Yumrepo <| |> -> Package <| provider == yum |>
This, finally, provides easy many to many relationships in Puppet, but it also opens
the door to massive dependency cycles. This last feature is a very powerful stick,
and you can considerably hurt yourself with it.

The following manifest:
case $var {
/match/: {
if $var =~ /matchagain/ {
}
}
}
is failing because the "=~" operators when matching sets an ephemeral
variable in the scope. But the case regex also did it, and since they
both belong to the same scope, and Puppet variables are immutables, the
scope raises an error.
This patch fixes this issue by adding to the current scope a stack
of ephemeral symbol tables. Each new match operator or case/selector
with regex adds a new scope. When we get out of the case/if/selector
structure the scope is reset to the ephemeral level we were when
entering it.
This way the following manifest produces the correct output:
case $var {
/match(rematch)/: {
notice("1. \$0 = $0, \$1 = $1")
if $var =~ /matchagain/ {
notice("2. \$0 = $0, \$1 = $1")
}
notice("3. \$0 = $0, \$1 = $1")
}
}
notice("4. \$0 = $0")
And the output is:
1. $0 = match, $1 = rematch
2. $0 = matchagain, $1 = rematch
3. $0 = match, $1 = rematch
4. $0 =

It is a setting that was added years ago as a backward
compatibility option and even if it still works, which
is questionable, it has no purpose any longer.
It just complicated the code and didn't do much, so it's gone
now.
Also simplified the interface of Leaf#evaluate_match, since it
was now using none of the passed-in options.
Finally, removed/migrated the last of the Selector/CaseStatement
test/unit tests.

This patch moves the syntactic aspects of string interpolation up
into the lexer/parser phase, preparatory to moving the semantic
portions down to the as yet unnamed futures resolution phase.
This is an enabling move, designed to allow:
* Futures resolution in and between interpolated strings
* Interpolation of hash elements into strings
* Removal of certain order-dependent paths
* Further modularization of the lexer/parser
The key change is switching from viewing strings with interpolation
as single lexical entities (which await later special case processing)
to viewing them as formulas for constructing strings, with the internal
structure of the string exposed by the parser.
Thus a string like:
"Hello $name, are you enjoying ${language_feature}?"
internally becomes something like:
concat("Hello ",$name,", are you enjoying ",$language_feature,"?")
where "concat" is an internal string concatenation function.
A few test cases to show the user observable effects of this change:
notice("string with ${'a nested single quoted string'} inside it.")
$v2 = 3+4
notice("string with ${['an array ',3,'+',4,'=',$v2]} in it.")
notice("string with ${(3+5)/4} nested math ops in it.")
...and so forth.
The key changes in the internals are:
* Unification of SQTEXT and DQTEXT into a new token type STRING (since
nothing past the lexer cares about the distinction.
* Creation of several new token types to represent the components of
an interpolated string:
DQPRE The initial portion of an interpolated string
DQMID The portion of a string betwixt two interpolations
DQPOST The final portion of an interpolated string
DQCONT The as-yet-unlexed portion after an interpolation
Thus, in the example above (phantom curly braces added for clarity),
DQPRE "Hello ${
DQMID }, are you enjoying ${
DQPOST }?"
DQCONT is a bookkeeping token and is never generated.
* Creation of a DOLLAR_VAR token to strip the "$" off of variables
with explicit dollar signs, so that the VARIABLEs produced from
things like "Test ${x}" (where the "$" has already been consumed)
do not fail for want of a "$"
* Reworking the grammar rules in the obvious way
* Introduction of a "concatenation" AST node type (which will be going
away in a subsequent refactor).
Note finally that this is a component of a set of interrelated refactors,
and some of the changes around the edges of the above will only makes
sense in context of the other parts.

I had only done this partway, because it seemed easier,
but not surprisingly, it ended up being more complex.
In addition to those renames, this commit includes fixes
to whatever tests I needed to fix to confirm that things
were again working. I think most of these broken
tests have been broken for a while.

I was using 'params' and 'parameters', so
I fixed that and extracted the differences in
how they handle parameters into a stubbable method.
This allowed me to almost entirely remove the subclass's
'initialize' method.

This commit is hopefully less messy than it
first appears, but it's certainly cross-cutting.
The reason for all of this is that we previously only
looked up builtin resource types from outside the parser,
but now that the defined resource types are available globally
via environments, we can push that lookup code to Resource.
Once we do that, however, we have to have environment and
namespace information in every resource.
Here I remove the Resource::Reference classes (except
the AST class), and use Resource instances instead. I
did this because the shared code between the two classes
got incredibly complicated, such that they should have had
a hierarchical relationship disallowed by their constants.
This complexity convinced me just to get rid of References
entirely.
I also make Puppet::Parser::Resource a subclass
of Puppet::Resource.
There are still broken tests in test/, but this was a big
enough commit I wanted to get it in.

The issue is that case/selectors are downcasing the value before it
is compared to the options.
Unfortunately regex are matching in a case sensitive way, which would
make the following manifest fail:
$var = "CaseSensitive"
case $var {
/CaseSensitive/: {
notice("worked")
}
default: {
fail "miserably"
}
}
This patch fixes the issue by making sure the regexp match is done
one the original (not downcased) value, but still doing a case
sensitive match.

This patch allow this syntax:
$hash[mykey] = 12
If the key already exist an error is raised. Hashes are essentially
write only, like puppet variables.

This bring a new container syntax to the Puppet DSL: hashes.
Hashes are defined like Ruby Hash:
{ key1 => val1, ... }
Hash keys are strings, but hash values can be any possible right
values admitted in Puppet DSL (ie function call, variables access...)
Currently it is possible:
1) to assign hashes to variable
$myhash = { key1 => "myval", key2 => $b }
2) to access hash members (recursively) from a variable containing
a hash (works for array too):
$myhash = { key => { subkey => "b" }}
notice($myhash[key][subjey]]
3) to use hash member access as resource title
4) to use hash in default definition parameter or resource parameter if
the type supports it (known for the moment).
It is not possible to string interpolate an hash access. If it proves
to be an issue it can be added or work-arounded with a string concatenation
operator easily.
It is not possible to use an hash as a resource title. This might be
possible once we support compound resource title.
Unlike the proposed syntax in the ticket it is not possible to assign
individual hash member (mostly to respect write once nature of variable
in puppet).

The following manifest doesn't work:
$foo = undef
case $foo {
undef: { notice("undef") }
default: { notice("defined") }
}
This is because "undef" scope variable are returned as an empty
string.
This patch introduces a behavior change:
Now, unassigned variable usage returns also undef.
This might produce some issues in existing manifests, although
care has been taken to allow correct behavior in the most commonly
used patterns.
For instance:
case $bar {
undef: { notice("undef") }
default: { notice("defined") }
}
will print "undef".
But matching undef in case/selector/if will also match "".
case $bar {
"": { notice("empty") }
default: { notice("defined") }
}
will print "empty".
Of course "" doesn't match undef :-)

This is a moderately ugly workaround for the MRI garbage collection
bug (see the ticket for details).
I explored several other potential solutions (notably, monkey
patching the routines that trigger the bug) but none of them were
satisfactory. Monkey patching sub, gsub, sub!, gsub!, etc., for
example, either changes the scoping of $~, $1, etc. in a way that
could potentially subtly change the meaning of programs or (if you
are clever) faithfully reproduces the behaviour of MRI--including
the memory leak.
I decided to go with the standardized and somewhat obnoxious never-
used optional argument as it was easy to automatically insert and
should be even easier to automatically find and remove if a better
fix is developed. It also should be obtrusive enough to escape
accidental removal in refactoring.

This patch fix this bug by adding more to_s methods to ast member
so that puppetdoc can just to_s the AST to reconstruct the original

Of course this is not perfect, but should work most of the time.

This commit extracts these three classes into a single
ResourceType class in the Parser heirarchy, now completely
independent of the AST heirarchy.
Most of the other changes are just changing the interface
to the new class, which is greatly simplified over the previous
classes.
This opens up the possibility of drastically simplifying a lot
of this other code, too -- in particular, replacing the reference
to the parser with a reference to the (soon to be renamed)
LoadedCode class.
