[0/5] guestfish: detect stdout-write failure
...bviously, including the absolute program name in the diagnostic is a bug.
It should be "guestfish", and there's already code to perform that
sanitization in the patch below. It fixes everything except the glibc
global variable, program_invocation_name, used by error, called by
atexit+close_stdout. I'll fix that via gnulib's progname module later
today or tomorrow. Note that all other diagnostics (e.g., below) do
use the sanitized name.
The second patch is to make guestfish write --help output
to stdout, not stderr, per convention. Also, since --help
output is pretty long, I find...

ssh client is setting O_NONBLOCK on a pipe shared with other processes
...set O_NONBLOCK are required to handle
EAGAIN or short counts. They *may* need to deal with EINTR but signals
don't come out of nowhere either and many programs run in an environment
where EINTR is also unexpected.
We are using GNU make 3.81 but newer versions of gmake do the same thing:

ssh client is setting O_NONBLOCK on a pipe shared with other processes
The quick summary is that we invoke git from a parallel invocation of
"make". Git invokes ssh to pull stuff from a remote repo. Ssh sets
O_NONBLOCK on stdout and stderr if they do not refer to a tty. During
our build, stderr refers to a pipe that other jobs run by make (and
make itself) may also write to, and since this is a parallel build,
they may write to that pipe while ssh has it

[PATCH v2 0/4] New getprogname module
Hi,
as discussed in [1], this series adds a new getprogname module.
All it does is providing a getprogname function, much like what is
found on e.g. *BSD systems, and using it in gnulib instead of progname.
Also, using it explicitly by modules avoids gnulib users the need of
either use the progname module (GPL), or to provide program_name (and
call set_program_name manually, which is not always
