f42df48a1b Don't reset the cache on pop if no deletion occurs
When the stack is being pop'd, it is not necessary to reset it if no
variable is either reset to its previous value or deleted.

446280ab6e run_once clause
When the run_once clause is present and set to a truthy value, the
instruction it is attached to will only be executed the first time it is
encountered.

9c4cc09021 Copy variables when storing them on the stack 2022-09-17 10:21:06 +02:00
0519be9316 Changed how variables work again
Script variables are not longer saved before entering a block. Only
variables declared as locals and loop variables are saved. This allows a
block to use `set_var` to change a variable.

46e675dedb Cleaner implementation of the variable cache
* Separate implementation that acts as a MutableMapping
  * I'm still not sure about this. Also, there is a design error in
    there, because it's not possible to "return" a value from a block
    unless it's written to a fact.

cbe1bd65bf loop - Always process the value using the templar
* When the loop value is a list, its items may be templates or
    structures which contain templates. Because of that, they need to go
    through the templar.

91ff8296d6 More cache/loop fixes
* When the loop variable state is restored, the cache must also be
    modified.
  * What needs to be done depends on whether a host fact by the same
    name also exist.
  * Fuck that cache thing. It's going away next time I can hack on this.

57bf02e79d Variable cache - Reset after block execution
* When a block is done executing, local variables must be restored to
    their previous values ; however, host variables may have been
    updated inside the block. Therefore it is necessary to reset the
    variable cache.
2022-09-04 23:16:56 +02:00
d1d997f7ae Actually use the variable cache
* The merged (host+local) variable cache should not be reset at each
    instruction.
2022-09-04 23:14:01 +02:00
7e5eb8e414 Fixed caching problem in set_fact
* Since facts have a lower priority than local variables, set_fact
    should only update the cache if no local variable uses the same
    name
2022-09-04 23:00:15 +02:00
a5b1ac5c4c Better loop variable state handling
* Loops caused local scripts variables to be backed up then restored,
    which would have caused a set_var in a loop to have no effect.
  * Instead, we back up the state of the variable (existing or not,
    value) and either restore the original value or delete the variable
    if it didn't exist.

cc439110ae Remove allowed field names from instruction data
* It's pointless to have a distinct set of allowed fields for each
    instruction in the program

5ef2ffc55c Debugging support
* Support for dumping parsed programs as strings (both a basic,
    repr-like version and an indented version that is easier to read)
  * Display the parsed program if verbosity is high enough
  * Program tracing if verbosity is high enough
2022-09-04 11:35:07 +02:00
7b44cdc731 create_group - add_host and parent options
* The `add_host` option can be used to add the current host to the
    group being created. It avoids having to use a separate `add_host`
    instruction in this case.
  * The `parent` option can specify the parent group. It avoids having
    to use a separate `add_child` instruction in this case.

5f719d7ab8 "block" instruction implemented
The "block" instruction allows mulitple instructions to be grouped in
order to be executed based on a single condition, in a common loop, with
a local variable scope. In addition, it provides a way to recover from
errors.
