This adds a function runner that runs pure functions. It will hopefully
be useful for speculative execution of functions for compile time
determination of types.
The exec resource was an early addition to the project, and it was due
for some fixes and integration into our automated tests. This patch
fixes a number of issues, and makes it ready for more general use.
If you run an import, you only include everything that's part of a
scope. This includes, variables, classes, and functions. Anything else
should cause a compile error. This cleans up the error by adding a
String() method to each Stmt in our AST.
Readfile had a bug where it sent an empty string on startup. This has
ben fixed, and it now waits until the file contents are ready before
sending a string.
Add option RefreshOnly (default to false) on print ressource, to print only when
notified by other resource. When a print is RefreshOnly, it can't be grouped anymore.
This adds the ability to wait with a timeout for CheckApply happenings
in a resource. This helps avoid unnecessary long sleeping and timing
guesses. This also adds a cleanup function to run at the end.
Some of the early code I wrote probably wouldn't pass my own reviews
today. Here's one example of a rare deadlock that could sometimes occur
when a Process/CheckApply caused a shutdown, but the bufio tried to send
on a channel that nobody was going to read any more. Now we properly
unblock that send with a context.
This adds back the retry loop around Process. This is done as a
separate commit so you can more easily see the logic of the retry magic
This commit is similar but different to the earlier commit adding retry
around Watch.
The engine core had some unfortunate bugs that were the result of some
early design errors when I wasn't as familiar with channels. I've
finally rewritten most of the bad parts, and I think it's much more
logical and stable now.
This also simplifies the resource API, since more of the work is done
completely in the engine, and hidden from view.
Lastly, this adds a few new metaparameters and associated code.
There are still some open problems left to solve, but hopefully this
brings us one step closer.
This adds a simulated engine that can run and test single resources. It
can't test all aspects and features that the engine supports, but is
probably pretty decent for testing the actual CheckApply and Watch
semantics. Be warned that it actually applies changes on your machine,
so please don't write tests that make undesirable changes.
This unbreaks the mcl bindata code. Of course we could change the parser
to allow this prefix, but this is cleaner. The packages still have a
core prefix, which it seems we could also remove, but this isn't
particularly important for anything.
Since the langpuppet GAPI creates fresh new CliContext objects,
it has to make sure to provide the original parent context, because
the child GAPIs expect to be able to access its data.
