The commit failed with:
svn: Commit failed (details follow):
svn: Server sent unexpected return value (400 Bad Request) in response to MKACTIVITY request for '/svn/llvm-project/!svn/act/171a3442-2c78-47b3-89ac-63b98af59774'
svn: Your commit message was left in a temporary file:
svn: '/home/dawn/dev/llvm_svnR146622/tools/lldb/svn-commit.tmp'
I tried checking out the tree with:
svn co https://llvm.org/svn/llvm-project
but that gave me:
svn: access to '/svn/llvm-project/!svn/vcc/default' forbidden
Please commit lldb_svnR147560_POSIX.patch for me?
Commit message is:
This patch combines common code from Linux and FreeBSD into
a new POSIX platform. It also contains fixes for 64bit FreeBSD.
The patch is based on changes by Mark Peek <mp at FreeBSD.org> and
"K. Macy" <kmacy at freebsd.org> in their github repo located at
https://github.com/fbsd/lldb.
Thanks,
-Dawn

> +/// The basic design of the ProcessMonitor is built around two threads.

> +/// One thread (@see SignalThread) simply blocks on a call to waitpid() looking
> +/// for changes in the debugee state. When a change is detected a
> +/// ProcessMessage is sent to the associated ProcessFreeBSD instance. This thread
> +/// "drives" state changes in the debugger.
> +///
> +/// The second thread (@see OperationThread) is responsible for two things 1)
> +/// launching or attaching to the inferior process, and then 2) servicing
> +/// operations such as register reads/writes, stepping, etc. See the comments
> +/// on the Operation class for more info as to why this is needed.
