Two listener sockets on same port
by Denis Kudriashov Jan. 31, 2017

Jan. 31, 2017

Hi, I remember in past there was some reports about it. And now I was a victim of this problem which is very difficult to debug. Pharo allows to start two listener sockets on same port. You will not see any error. State of both sockets will be identical. "socket isValid, socket status" will be always correct for both instances. You can play with sockets with following code: (socket := Socket newTCP) setOption: 'TCP_NODELAY' value: 1; setOption: 'SO_SNDBUF' value: 4096; setOption: 'SO_RCVBUF' value: 4096. socket listenOn: 40424 backlogSize: 32. When many listener sockets are created. Only first will receive connections. So first server will work. But others will not with no way to know why. But more dramatical scenario is when first socket becomes collected as garbage which will destroy it. In this case You will be completely confusing why your single instance in image is not working. Such case is of course some bug in how you manage sockets. But that's the problem: It is now impossible to debug such cases. Can we fix it? Is it possible to signal error when socket is not really listen? Best regards, Denis

Form/Spec based UI's in GT inspector extensions
by Torsten Bergmann Jan. 31, 2017

Jan. 31, 2017

Hi, there are a lot of examples for GT inspector extensions in the image. I've seen #tree(s), #list(s) or #table like UI's are used. Even a #text or an "image" displaying a morph (using #form keyword sent to the given composite). It is very easy to provide extension methods to adopt the inspector to own needs and I wish people would use this more in our environment and according projects. But what I still miss is an easy way to extend the inspector with REAL FORMS (which are dialog like) to better display and manipulate attributes/ivars of an object. To give a few examples: ======================= When I inspect a color instance I would like to see (and change) the RGB values as well as the HEX representation in a form in an own tab. Similar as if I would be changing a color in a graphics program. I would like to lively manipulate the RGB values easily with sliders instead of sending messages to self in the "first" inspector code pane/tab. Or think of a Person class where you can provide an own custom inspector pane to display/change the name and first name in an edit field or select the date of birth in a datepicker together with a button to apply the new values to the object. Think of a database connection object where I can manipulate the ivar storing the connection string in an edit field but also provide a "Reconnect" in the button after I changed it. Currently we by default we have the "Raw" tab and need to manipulate the object state with expressions in the code pane. For me this is not interactive enough and Pharo has much potential to be a lively objects environment here. Long story short: ================= 1. Is there any support for such kind of dialog based UI's in the inspector tabs/composites. 2. Is there any support to use Spec based UIs to extend the GT inspector? 3. Is there support to build simple UI forms for the inspector with labels and edit fields, combo boxes, radio buttons, date fields, field set, buttons, ... like in [2]. 4. If we dont have such a beast yet I guess we should work into this direction because it would make Pharo not only a lively (for message sending) but very useful environment for direct object interaction/manipulation of states. Are there any plans/work on this already? If not what would be needed to achieve that? Maybe a GSOC project? Thanks T.
