Hi guys,
I am having an issue with Events in Forge. I would like to get a list
of Resources modified by a forge command, after a forge command has
been executed.
Fortunately, forge fires events when command execution completes
(either successfully, or unsuccessfully) and when resources are
created/modified/deteled/etc. Sadly, it fires CommandExecuted event
before any of ResourceEvents. (EventBusInvoker listens to
CommandExecuted event and fires all ResourceEvents queued in the
EventBus).
I expect ResourceEvents to be fired before the CommandExecuted event
(which would correspond to what actually happends). I tried commenting
out code inside of EventBusInvoker's fire method and adding
"bus.fireAll();" into Execution class (right before firing
CommandExecuted event) but that doesn't seem to work.
How could I fire ResourceEvents before CommandExecuted event? Or is
there another way to get a list of modified resources during forge
command exection?
What does this line do? Is forge multi-threaded?
"Thread.currentThread().setContextClassLoader(current);"

That line is to ensure proper ClassLoading while running in a modular
environment.
Before I answer this, it might be better to ask why you want to fire
ResourceEvents before CommandExecuted event. I think I agree with the
change to fire CommandExecuted after, but I just want to know to be sure.
I think that introducing a second event might be useful if what you are
trying to do is capture all changed resources:
EnteredWaitState to notify when the shell is again waiting for user input.
There may be an event like this already. Also, is it possible to do what
you need without the resource events entirely? Just a thought. Doesn't GIT
already tell you which files have changed somehow?

Could you please explain a little more what does "proper ClassLoading
while running in a modular environment" actually mean. Or maybe I
should ask it this way: do you think it's important for me to
understand that?
I want to fire ResourceEvents before CommandExecuted event because
that corresponds to what actually happens (files are modified during
the execution of the forge command, not after). Here is an
illustration of what I mean:

I don't mind introducing another event EnteredWaitState but I don't
think it would make sense to use it, in order to acquire the resources
list. UndoPlugin will have to wait for the EnteredWaitState event and
then use polling of some kind to get the list of resources since there
is no way to know how many events are going to be fired or whether
EventBus has finished firing events. EnteredWaitState event could be
helpful for other uses, e.g. calling "git add --all; git commit" right
after (only if CommandExecuted behavior will not be modified).
Yes, "git add --all; git commit" would work. I was thinking about
tricky scenarios related to "git add all" but it should be fine.
