f87de76b9f RCU: Fix race condition between writer/reader 
This uses an atomic counter and spins only on the writer side, which
preserves realtime behavior on the reader side. The spinning yields (by
using the same Boost function from Boost spinlocks) to be
scheduler-friendly.

Fixing this bug also lets us be able to confidently drop garbage early
in the writer if appropriate, so do that and avoid keeping dead wood if
possible.

This reverts commit f95439a502:

c2618903ae Allow to overload drop_references() 
This is useful in cases where an object owns child objects
which in turn hold a reference to the parent.

In this case PluginInsert has-a Plugin, which may have a reference
to the insert or the Route.

fa495b7727 Account for additional TLS on macOS/X 
On GLIBC systems pbd_stack_size() adds __pthread_get_minstack,
this is no available on mac systems, causing issues with some
libraries used by plugins.

e3dcd1f5d7 Only try using __pthread_get_minstack on glibc 
This is a glibc-only extension, so don't bother on other platforms.
Also, according to POSIX, PTHREAD_STACK_MIN is defined in limits.h, so
include climits just to be safe.

e0548fa798 Offset stack-size by current TLS #8200 
Some libraries use thread locals and hence increase the min
requirement.

This is seen on void-linux for example:

> linking a minimal program against cairo gives a
> __static_tls_size of 43008 bytes.
> Doing the same on Ubuntu focal and Debian bullseye,
> __static_tls_size is only 4608.

a660077c97 PlaybackBuffer: extend API to include write_ptr()

 2020-05-13 23:55:02 -06:00
Paul Davis
98d56d6b21 Add API to PlaybackBuffer to compute amount of data that can overwritten 
The distance is between a given offset in the buffer (probably a
read position at some point in time) and the write ptr. Any data after
the write ptr is "old" and not readable, and thus not worth overwriting
since we would not read it anyway.
