# BST-TIMEOUT: 300
#
# civetweb 1.16 (meta-networking recipes-connectivity) -- an embeddable
# HTTP/HTTPS server: one C file behind include/civetweb.h, plus a thin main.c
# that turns the same library into a standalone server. This image's SECOND HTTP
# server after lighttpd, and it is here for the half lighttpd cannot show: the
# EMBEDDING API. lighttpd is a program you configure; civetweb is a library you
# mg_start() inside your own process and hang C functions off with
# mg_set_request_handler(). Both halves are covered below, and each is an
# independent witness for the other.
#
# EVERY EXPECTED VALUE BELOW IS PINNED FROM AN x86-64 CONTROL, not guessed: the
# same SRCREV (d7ba35bb) configured with exactly the recipe's cmake switches,
# built natively, and driven through this same sequence on 2026-08-18. Where a
# case says "control", that is what it means.
#
# FOUR PLATFORM FACTS SHAPE THIS FILE.
#
#  1. THREADS DO NOT WORK HERE, AND THAT IS WHY MOST OF THIS FILE IS RED.
#     civetweb is a threaded server -- mg_start() creates a master thread plus
#     num_threads workers, and mg_stop() joins them -- and this platform refuses
#     a thread-mode clone outright. MEASURED on target, 2026-08-18, the kernel
#     saying it in its own voice:
#
#       [k] wasm32: REFUSING thread-mode clone (CLONE_VM, pid=70, flags=0x3d0f00)
#           with EAGAIN — the coro substrate's runtime protocol state is
#           single-lane per process; a second Worker lane over the same
#           user_memory is a structural protocol violation, not a schedulable
#           thread. pthread_create() gets EAGAIN (catchable std::system_error).
#           Opt-in: HWJS_EXPERIMENTAL_THREAD_CLONE=1.
#
#     and civetweb, faithfully:
#
#       Failed to start CivetWeb V1.16 with code 9: Cannot create first worker
#       thread: error 11
#
#     So `civetweb` cannot serve on this image, and neither can any embedder of
#     libcivetweb. That is a PLATFORM gap, not a defect in this port: it is
#     brintos/linux-in-the-browser#85 (open -- the single-lane coro park
#     protocol), with brintos/hardwarejs#12 behind it for the join side.
#
#     THE OPT-IN IS NOT A WAY OUT, and it is named here so nobody spends an hour
#     discovering that. HWJS_EXPERIMENTAL_THREAD_CLONE=1 is read from the HOST
#     node process's environment (hardwarejs/src/worker.mjs), so nothing running
#     inside the guest -- this suite included -- can set it; and worker.mjs's own
#     comment says the path it re-opens ends in glibc's "futex facility returned
#     an unexpected error code" and exit 127. It is a bring-up hatch, not a
#     working mode.
#
#     EVERY CASE BLOCKED BY THIS IS LEFT RED AND ATTRIBUTED, never skipped, so it
#     flips green by itself when #85 lands -- the same choice 79-libdaq makes for
#     daqtest-static. Each such red carries $THREADS in its detail, so a sweep can
#     separate "the platform has no threads" from "civetweb regressed" by grep,
#     and no red here is unattributed.
#
#     WHAT IS NOT RED IS NOT NOTHING. The package, its artifacts, the whole
#     no-socket CLI surface and every compiled-in feature are asserted and pass,
#     and two cases below assert the thing that is genuinely GOOD about this
#     port's behaviour under the gap: civetweb DIAGNOSES the refusal and exits,
#     and libcivetweb returns mg_start()==NULL, rather than either of them
#     trapping and taking the guest with it. Those two are written to stay true
#     AFTER threads land, so they are not assertions that rot.
#  2. `sleep N` DOES NOT SLEEP (brintos/linux#48,
#     linux-in-the-browser#120), and timeout(1) DID NOT FIRE before the
#     brintos/linux#77 fix, alarm(2) being ENOSYS. Every wait below therefore
#     spins against /proc/uptime and every bound is enforced by this file, not
#     by a timer.
#  3. EVERY EXEC COSTS A PARK SLOT, so this file spends as few as it can --
#     and that discipline is file-wide, not just inside loops. hwjs-cc#69
#     orphans a park slot per exec and brintos/hardwarejs#28 leaves the lane
#     unreclaimed afterwards, so an exec-happy suite does not merely run slowly:
#     it can WEDGE THE GUEST and take every result with it. Measured on this
#     file, 2026-08-18: at 62 command substitutions it wedged 2 runs out of 3
#     ("hwjs-rt VIOLATION: set-over-set: parked slot not empty at a new park"
#     inside wasm32_user_exec_load, cases=0), while 84-lmbench on the SAME image
#     and boot ran 27/27 -- so the image was healthy and this file was the
#     variable. It now spends 33.
#
#     Concretely: `read < /proc/uptime` and `[ -d /proc/N ]` are builtins, so no
#     poll loop spends a process per iteration; files are slurped with `read`
#     and matched with `case` rather than through `$(cat f)`; /proc/net/tcp is
#     parsed with `read` rather than `awk`; and the probe's twenty-six
#     measurements are parsed in ONE builtin pass rather than one `awk` apiece.
#     `check_out` is avoided throughout because it forks per case (`check_eq`
#     does not, and is used freely). What remains is only what genuinely needs a
#     process: the subjects themselves, one `find`, one `cmp`, `nc` and `wget`.
#  4. EVERYTHING IS NUMERIC AND ON LOOPBACK. 127.0.0.1 by address, so nothing
#     traverses getaddrinfo(3)'s dns leg -- independently broken on this image
#     (linux-in-the-browser#96) and it would otherwise turn a web-server result
#     into a resolver result. lo is the only interface this guest has.
#
# PORTS 8088/8089/8090, not 80 and not lighttpd's 8080: we are root so any port
# would bind, and using neither the privileged default nor the neighbouring
# suite's port means a server this file did not start cannot be mistaken for one
# it did.
