* Scope[] now returns nil for undefined variablesLuke Kanies2011-07-151-3/+4
| | | | | | | | | | | | | | | Given that we have the 'include?' method, this feature is unnecessary, and it makes sense to convert to more ruby-like behavior. Any code that previously checked whether lookupvar (or the new []) returned :undefined should now check whether 'scope.include?(var)'. Thus, you can have the same behavior, but it takes a bit different code to get it. Signed-off-by: Luke Kanies <luke@puppetlabs.com> Reviewed-by: Nick Lewis <nick@puppetlabs.com>
* Adding []/[]= support to ScopeLuke Kanies2011-07-151-2/+2
| | | | | | | | | | | | | | | | | | The interface to scope is much clearer this way anyway, but this is needed to integrate Puppet with Hiera[1]. It just provides hash-like behavior to Scope, which Hiera and others can now easily rely on. I also went through all of the code that used Scope#lookupvar and Scope#setvar and changed it if possible, and at the same time cleaned up a lot of tests that were unnecessarily stubbing (and thus making it difficult to tell if I had actually broken anything). 1 - https://github.com/ripienaar/hiera Signed-off-by: Luke Kanies <luke@puppetlabs.com> Reviewed-by: Nick Lewis <nick@puppetlabs.com>
* (#7681) Allow array variables as resource referencesNick Lewis2011-05-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit df088c9ba16dce50c17a79920c1ac186db67b9e9 introduced a regression where $files = ["/tmp/one", "/tmp/two"] file { "/tmp/one": content => "one", } file { "/tmp/two": content => "two", } file { "/tmp/three": content => "three", require => File[$files], } no longer worked. File[$files] was concatenating the elements of $files to create a single title, instead of expanding to multiple File dependencies. Since resource reference titles are implicitly wrapped in an array, if one of the elements of that array is a variable containing an array, the list of titles is a nested array. Prior to the change causing the regression, we would flatten arrays when evaluating them, under certain circumstances. We no longer ever flatten AST arrays when evaluating them, so anywhere that we really do need a flattened array, we have to manually flatten it. ResourceReference expects its list of titles to be a single, flat list of titles, so we have to make it so. Paired-with: Jacob Helwig <jacob@puppetlabs.com>
* Towards 5027 -- add options hash to lookupvar as with setvarMarkus Roberts2011-04-122-3/+3
| | | | | | | | | | This patch adds an options hash to lookupvar analogous to the one taken by setvar and uses it to pass in source location for error reporting. It also fixes the mechanism used by setvar (file was not being passed correctly), adds line and file information to errors in templates, and extends/corrects tests. As presently written it does not gather userful line numbers from inline templates and there are no tests for the template line number generation.
* Refactor en route to #5027 -- remove usestring parameter from lookupvarMarkus Roberts2011-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usestring parameter to lookupvar was objectionable for several reasons; first, it performed a function orthogonal to the main purpose of the method, second its default was the least common value, and third it was causing other code to work for reasons that were not obvious (extlookup). This refactor breaks the value-transforming function out into a seperate method which allows the user to specify the value to be used in lieu of :undef and removes the parameter. The function, Scope#undef_as(default,exp) is written so that it can be used in user code (templates, functions, etc.) if needed. This refactor will introduce a user-visible behaviour change in the case where users were counting on lookupvar to return "" for undefined variables. The best solution is to have them use undef_as, replacing: lookupvar('myvar') with undef_as('',lookupvar('myvar')) (with the option to specify another default value if desired). If this is too objectionable, we could rename the existing lookupvar as raw_lookupvar and define def lookupvar(v) undef_as('',raw_lookupvar(v)) end to restore the present behaviour.

This allows the same code paths to be used to handle the results of parsing both .pp and .rb files. This makes .rb files work properly in multiple environments, because the types are now instantiated by code that is aware of which environment the compilation is happening in. It also reduces the risk of future changes breaking .rb file support. Also, switched to using "instance_eval" rather than "require" to evaluate the contents of the .rb file. This ensures that if the file has to be recompiled (because it became stale), it will actually get re-evaluated. As a side benefit, ResourceTypeAPI is now a class rather than a mixin to Object, so its methods do not pollute the global namespace. To reduce the risk of customers coming to rely on implementation details of the resource type API, changed its methods to return nil, and removed methods from it that were misleadingly labeled as "private".

("Statement" could sometimes represent a single item because a single resource declaration could represent multiple resources). This complicated other grammar rules and caused ambiguous handling of nested arrays. Also made these changes to the AST class hierarchy: - ResourceInstance no longer derives from ASTArray. This relationship was not meaningful because a ResourceInstance is a (title, parameters) pair, not an array, and it produced complications when we wanted to represent an array of ResourceInstance objects. - Resource no longer derives from ResourceReference. No significant functionality was being inherited and the relationship doesn't make sense in an AST context. - ResourceOverride no longer derives from Resource. No significant functionality was being inherited and the relationship doesn't make sense in an AST context. - Resource can now represent a compound resource instance such as "notify { foo: ; bar: }". This saves the parser from having to use represent a statement as an array of objects. - ASTArray's evaluate method never flattens out arrays of arrays.

Instead, the parser would instantiate types and insert them into known_resource_types as soon as they were parsed. This made it difficult to distinguish which types had come from the file that was just parsed and which types had been loaded previously, which led to bug 4496. A side-effect of this change is that the user is no longer allowed to define types inside of conditional constructs (such as if/else). This was allowed before but had unexpected semantics (bugs 4521 and 4522). It is still possible, however, to place an "include" statement inside a conditional construct, and have that "include" statement trigger the autoloading of a file that instantiates types.

| | | | | | | | 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
* [#3921] Remove unnecessary require 'puppet/resource'Rein Henrichs2010-02-171-1/+0

* Fixing #448 - relationships have their own syntaxLuke Kanies2010-02-171-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Luke Kanies <luke@puppetlabs.com>
* Fix #3155 - prevent error when using two matching regex in cascadeBrice Figureau2010-02-173-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 = Signed-off-by: Brice Figureau <brice-puppet@daysofwonder.com>
