ezthreads - thread pool support
«
on:
April 15, 2020, 06:05:41 am »
added thread pool support to ezthreads, hope this helps someone out there,
some features:
works with await (entire pool or specific group id)
thread pool is itself an IEZThread, so all events are supported
safe capturing of success / error cases for individual threads
global arguments passed to pool carry to workers
basic usage:
Code: Pascal
[Select]
[+]
[-]
(*
test that shows two simple tasks completing in parallel
by an ezthread pool
*)
procedure
TestTwoTasks
;
var
LPool
:
IEZThreadPool
;
LJobOneFinished
,
LJobTwoFinished
:
Boolean
;
//simple parallel job
procedure
JobOne
(
const
AThread
:
IEZThread
)
;
begin
//do some work
Sleep
(
100
)
;
LJobOneFinished
:
=
True
;
end
;
//simple parallel job
procedure
JobTwo
(
const
AThread
:
IEZThread
)
;
begin
//do some work
Sleep
(
100
)
;
LJobTwoFinished
:
=
True
;
end
;
begin
//flags for checking if both jobs finished
LJobOneFinished
:
=
False
;
LJobTwoFinished
:
=
False
;
//init a pool with two workers
LPool
:
=
NewEZThreadPool
(
2
)
;
//work two jobs
LPool
.
Queue
(
JobOne
,
nil
,
nil
)
.
Queue
(
JobTwo
,
nil
,
nil
)
.
Start
;
//start the pool
//wait until both jobs finish
Await
(
LPool
)
;
//write status
WriteLn
(
Format
(
'TestTwoTasks::[success]:%s'
,
[
BoolToStr
(
LJobOneFinished
and
LJobTwoFinished
,
True
)
]
)
)
;
end
;

Could this work with the normal FPC mode?

You'll probably need to use at least mode
ObjFPC
. The compiler's default mode does not support classes.

Thanks @Pascaldragon, I wasn't sure on this since I normally use mode delphi, but this does work fine for ObjFpc too as you pointed out
