FIX.org, NEXT.md, DISCUSS.org, docs/DISCUSS.md and the session handoff at the
root are one TODO.org now: 293 entries under seven subsystem headings, each
carrying an org keyword that says where it stands. A DONE entry is a few lines
saying what was decided and what that rules out; the reasoning that would not
compress — the embedding spike and the four reports the hand-written x86
backend was built from — moved into docs/BUILT.md instead, and its entries
point there in one line.
Every entry was checked against the tree before it got a keyword, and the
prose was wrong in both directions. Things the deleted files called open were
built: the first-evaluation stall, main being redefinable, macro parameter
lists, the type-limit constants, the array constructors, the byte fills,
inc/dec, the discard's fontification, the Emacs buffers, rt_die's _exit, the
backtrace surface, and the acceptance failure that could print and still exit
zero. Things they called done were not: the backend reports' no-plan buckets
had gone stale in the other direction, the value-dependent defvar was
superseded rather than built, and macro-expansion source locations are on an
unmerged lane, so that entry is NEXT and names the branch.
Every comment that cited one of the five by name now cites a heading that
exists, in TODO.org or in docs/BUILT.md. The session reports under
docs/handoffs/ keep naming the files they worked on, because rewriting them
would falsify what those sessions did; each carries a note saying where the
content went.
Ten test binaries share a directory and had shared nothing in it but
watchdog.ml. Everything else each one needed it wrote out again: the
failure counter and its FAIL line, the three-line report tail, a poll,
a socket connect, the wait for a [flan dev] daemon to bind, a substring
search, and the Load -> Check -> Reach.link front half of a compile.
[listening] was the clearest case. Three copies, byte for byte apart
from one comment, and two of them said in that comment that they were
kept separate because "these three files have no module between them".
That was not true when it was written: watchdog.ml was already named in
the same (modules ...) stanzas. test_support.ml is the second such
module, wired the same way, and those two sentences go with the copies
they were explaining.
test_repl.ml's [quote] was Wire.quote character for character, in a file
that already links Wire and already names Wire.quote in a comment about
what the case below it is checking. It is Wire.quote now.
One real behaviour change, and it is a fix. [connect] existed twice over
with different retries: the agent's narrowed to ECONNREFUSED with a
comment saying why -- the socket file appears at bind, a moment before
listen -- while dev's and repl's retried any Unix_error, which meant an
ENOENT or an EACCES was retried to the full timeout before raising
something the reader still had to interpret. The shared one takes the
narrow version. Every caller connects to a socket [listening] has
already seen on disk, so the race it does catch is the only one left.
The rest is left where it is, on purpose. The three output-capturing
[run]s differ in what they wrap -- a pid suffix, a sanitizer environment,
a valgrind invocation -- and are not the same function. The report tails
in test_repl, test_web and the two sweep binaries print different things
for different reasons. The per-file scratch prefixes are the feature that
keeps two suites running at once from unlinking each other's sockets, so
the shared helper takes the prefix rather than choosing one. And the
[match Sys.command "command -v clang ..."] probes stay as they are:
their skip lines are output this suite pins.
bin/main.ml has the compile pipeline written out twice more. Left alone
-- this was a test/-scoped change and bin/ should not be reaching into a
test module -- and noted in FIX.org as what it actually needs, which is
the pipeline moving into lib/.
dune test: exit 0, and its output is the same line for line once the
temp-directory hash and the millisecond counts are normalised.
