run Odoo with workers in devcontainer
lanuch.json as

{
      "name": "Python: odoo-bin",
      "type": "python",
      "request": "launch",
      "program": "odoo-bin",
      "args": ["-c", "config/odoo.conf"],
      "console": "integratedTerminal",
      "justMyCode": true,
      "gevent": true,
      "cwd": "${workspaceFolder}"

    },

breakpoint not worked,

but run Odoo with thread mode in devcontainer
lanuch.json as

{
      "name": "Python: odoo-bin",
      "type": "python",
      "request": "launch",
      "program": "odoo-bin",
      "args": ["-c", "config/odoo.conf"],
      "console": "integratedTerminal",
      "justMyCode": true,
      // "gevent": true,
      "cwd": "${workspaceFolder}"

    },

breakpoint worked,

workers > 0 is workers mode. https://github.com/jeffery9/odoo-devcontainer/blob/3344530afa9685888b5b75b4594941fd0213c064/config/odoo.conf#L59

Probably related to #1206. Can you try using debugpy.breakpoint() to trigger one manually and see if that works for you?

[jeffery9]

when workers > 0 Odoo run in multi-process and multi-thread mode and with gevent patched too.

[jeffery9]

once turn off gevent=True, debug in workers mode is ok, but raise error

It seems that the gevent monkey-patching is being used.
Please set an environment variable with:
GEVENT_SUPPORT=True
to enable gevent support in the debugger.

the working launch.json

      "name": "Python: odoo-bin",
      "type": "python",

      "justMyCode": false,
      // "gevent": true,
      "subProcess": true,
      "cwd": "${workspaceFolder}"

    },

there have another prolem: it is can't shudown debug process in one click.

It seems like Odoo is doing some unusual stuff, so we might have to add some specific support for it to make it work properly, on top of gevent support.

[jeffery9]

setup monkey patch as

# Is the server running with gevent.
evented = False
if len(sys.argv) > 1 and sys.argv[1] == 'gevent':
    sys.argv.remove('gevent')
    import gevent.monkey
    import psycopg2
    from gevent.socket import wait_read, wait_write
    gevent.monkey.patch_all()

    def gevent_wait_callback(conn, timeout=None):
        """A wait callback useful to allow gevent to work with Psycopg."""

        while 1:
            state = conn.poll()
            if state == psycopg2.extensions.POLL_OK:
                break
            elif state == psycopg2.extensions.POLL_READ:
                wait_read(conn.fileno(), timeout=timeout)
            elif state == psycopg2.extensions.POLL_WRITE:
                wait_write(conn.fileno(), timeout=timeout)
            else:
                raise psycopg2.OperationalError(
                    "Bad result from poll: %r" % state)
    psycopg2.extensions.set_wait_callback(gevent_wait_callback)
    evented = True

hope this should be helps.

thanks.

Any news about this ?

Still cannot debug Odoo with multiple workers even with gevent and subProcess set to true.
It appears that the debugger is attaching to only one of the subprocesses (in my case the gevent / long polling process)
