Hi Cygwin friends and users,
I released a new TEST version of Cygwin. The version number is
2.2.0-0.1.
This test release needs some good old-fashioned testing.
While the new features in this release are only interesting to
developers again, there's an intrusive under-the-hood change which just
needs testing in as many scenarios as possible.
==================================== tl;dr ==================================
Details aside, the interesting thing here is plain and simple this:
Does your stuff still work as with 2.1.0? No regression?
============================================================================
The boring details:
The under-the-hood change is this: Certain functions in Cygwin were
using very big buffers (32K, 64K, and more) on the stack. While this
is not much of a problem with the normal stacksize of 2 Megs, it's
been a lot of stack pressure on an application-provided patch. Yada,
yada.
For devs only:
2.2.0 comes with four new functions: getcontext, setcontext,
makecontext and swapcontext.
My own testing included two very simple self-written STCs, as well
as the example code from http://linux.die.net/man/3/makecontext, as
well as the glibc testcase tst-makecontext3.c.
As with the sigaltstack stuff, I'd be grateful if curious developers
would give this implementation a test. If it doesn't work as desired,
please consider to create simple reproduces in plain C.
Discussing aspects of this implementation may be best handled on the
cygwin-developers mailing list or the #cygwin-developers IRC channel
on Freenode.
Have fun,
Corinna
