Re: Checking If Methods Are Preemptive Ready

I am pretty sure that the METHOD GET ATTRIBUTES command will also return that 
information.

In my Code Analysis component, if you open the “Explorer” window there is the 
ability to filter the methods based on the preemptive capable attributes. Super 
useful and you can do it live.

Re: Checking If Methods Are Preemptive Ready

[Cannon Smith via 4D_Tech]

Hi Wayne,

Thanks for the idea. So far the symbols files has provided what I need. Not as 
simple to parse as if it had been spit out in JSON, but okay. Mostly I’m trying 
to get an idea of which of my “foundation” modules are not thread safe, but 
could be.

Thanks.

Re: Checking If Methods Are Preemptive Ready

[Keisuke Miyako via 4D_Tech]

that might be one way to develop.

alternatively you could limit the list to all four types of "starter" methods:

1 Execute on server
2 New process
3 CALL WORKER
4 method called via menu item with "new process" enabled

there is really no need to examine every single subroutine.

that said, moving forward,
I suppose it would be good practice to make sure new project methods are marked 
as preemptive-only.

then, if compilation fails (you call a UI or printing command, for example)
you can decide whether to delegate the task to a cooperative process (CALL 
FORM),
use Signal, or uncheck the preemptive checkbox.

Re: Checking If Methods Are Preemptive Ready

[Wayne Stewart via 4D_Tech]

Cannon,

I can't find the db I did this in but what I did was this:

METHOD GET PATHS(Path project method;$MethodNames_at)
METHOD GET ATTRIBUTES($MethodNames_at;$Attributes_ao)

Create a new array with those that area already marked as preemptive
safe.  Save it somewhere
Then use METHOD SET ATTRIBUTES to set them all to preemptive safe.
Compile and enjoy all the errors coming in.

You should be able to work through the list (slowly).
If you run out of time reapply the original set of attributes from the
initial call.

Then repeat until you've got everything that is safe labelled that way.

Regards,

Wayne

Re: Checking If Methods Are Preemptive Ready

[Keisuke Miyako via 4D_Tech]

that's right, method attributes only inform you of their preferences.

you could enable symbol file generation, compile, and look at the bottom of the 
generated symbol file.

Re: Checking If Methods Are Preemptive Ready

[Cannon Smith via 4D_Tech]

Hi Dani,

I believe that preemptive capable in that context just means that you’ve set 
the method properties that way. I don’t think it means that if you tried to 
compile the code would actually work in a preemptive context. I’d be happy to 
be corrected if I’m wrong?

Thanks.

Hello,

If you activate the generation of the symbol file in the compilation 
preferences, compile your database then open the myDtabase_symbols.txt files 
created near the structure file, All methods are listed at the end of the file 
with the status "Thread Safe" or "Thread Unsafe".

Checking If Methods Are Preemptive Ready

[Cannon Smith via 4D_Tech]

Does anyone know if there is a way to get a list of methods that are (or are 
not) preemptive ready?

Thanks.
