Máximo Castañeda aac110fbc0 Deskbar: Defend against applications quitting before finished launching.
If an application quits before it has finished handling its launch
we may not get its icons, which we try to access later on. Tell the
caller and don't add that group, we were going to remove it anyway.

If an application quits while we are iterating the team list
limited by a previous count, we may access an item outside the list.
Protect list accesses with the subscribers lock so that we are
locking in Add/RemoveTeam.

Fixes #20039, #20250.

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.

Contributing

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
