Priority: medium
Bug ID: 83430
Assignee: [email protected]
Blocks: 83429
Summary: Document client threading and event queues
Severity: enhancement
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: All
Status: NEW
Version: unspecified
Component: wayland
Product: Wayland
Write a chapter to the "big docs" about client side threading and event queues.
- dispatching a queue from more than one thread is a bad idea; explain why
- therefore, every thread that needs to dispatch should have its own queue
- also every piece of software that needs to dispatch in a controlled context
needs its own queue (e.g. libEGL)
- the client API is not multi-thread-dispatch-safe (wl_display_roundtrip)
- a new wl_proxy inherits its factory's queue
- destroying a queue while wl_proxies on it exist is a mistake and may lead to
use-after-free when events on that wl_proxy arrive
- wl_display contains the default queue
