[OpenIndiana-discuss] btop illumos/OpenIndiana port — PR up, looking for testers

[Alex Gorouvein]

Peter,

Thanks for testing this so quickly, and for the detailed notes — genuinely
helpful.

Quick update: I've pushed a fix for a crash on terminal resize. Turned out
`signal()` has one-shot (System V) semantics on illumos/Solaris, so btop's
SIGWINCH/SIGUSR1 handlers were getting reset to default after their first
delivery — a second resize (or a second Ctrl-C) could kill the process
outright with no core dump or log entry. Now using sigaction() instead.
This affected OpenIndiana too, not just Solaris, so worth a look if you hit
anything like that.

Also done: renamed src/openindiana to src/sunos per your suggestion, and
added optional Solaris 10 x86 support (build with S10=true) — cross-built
on an illumos host with a modern GCC, since Solaris 10 has no C++23
compiler of its own, with a small libc compat shim covering what it's
missing.

Still working through your other three points — the fs/sys/buf.h collision,
the find/getconf portability on native Solaris, and making
-static-libstdc++ opt-in (agreed it shouldn't be forced given Solaris has
no static libstdc++). Will follow up once those are in.

On the blank CPU panel on SPARC — I don't have SPARC hardware to test
against, so if you get a chance, `kstat -p cpu_stat:0` on that machine
would help me see whether the counter names or layout differ from what the
collector expects.

Thanks again — this is exactly the kind of testing I was hoping for.
