[ANN] Roadmap progress report November 2019

Hello,

I am sorry for the delay, last week was very chaotic :)

Spec2
---
- Make SpComponentListPresenter to acquire "list properties":
        - selection (single, multiple)
        - it can respond to #contextMenu:
        - takeKeyboardFocus
- Lists/Trees/Tables now can be searched (still "standard" implementation, misses a search by model)
- Lists/Trees/Tables now can be sorted

Spec2 + Gtk
---
- [Worker VM] Running event loop on main thread while VM runs on worker thread.
- Modify startup to automatically decide if it can run GtkMainRunLoop or GtkPollingRunLoop, depending on where is running the VM.
- Make backend to properly defer executions to main thread when needed (implemented GtkRunLoop class>>defer: for that)
- Fix the trunk for windows (detected a problem while coexisting SDL2 and GTK3 that may cause the need to use exclusively one or the other).

TFFI
---
- Improve callout performance using a semaphore pool instead creating a new one each call

VM
---
- Work on Worker VM (allow VM to run in a worker thread).
        - Merged with headless trunk
        - Merged with AIO interrupt
        - Now can be tested (but still some interruptions missing)
- (Re)making an environment to build on linux (to test the problem while building Debian/Ubuntu modern distributions)
- Investigating the garbage collection corruption problem. Integrating proposed solution of Clément Bera.
- Fixing problems in main thread worker and interruptable async IO.

Others
---
- Voyage-UnQLite backend working with new TFFI (this is to make some testing around using several libraries/threads in a single image)
- ObjCBridge package working with new TFFI (for same reasons as before)

Smalltalks 2019
---
- Presentation in Smalltalks 2019 (Neuquén, Argentina): Contributing to Pharo, new things for Pharo 8.
- Meetings during Smalltalks.
- Presentation in universities and companies in Argentina.

Hi,

Worker VM just describes the capability of the VM to run in a worker thread (which means we can keep the main thread to other stuff, like running the event loop).
Now, while I know there is some work/experiments to revive something like the hydra (running several images in one VM, or several copies of same image), I do not know the opposite :)

And this Worker VM (we call it “ogre”, because it has two heads :P) will work with the regular image, nothing changed there.
