4c336687ef Master's error recovery is merged, and the refusal memos are consulted only where a refusal is raised 2026-09-25 17:03:32 +07:00
96dbcb1f2f An expression that makes a function value keeps its module mapped, a process a merged program starts does not take the session's socket, and an evaluation's value is its own expression's and not one a restart resumed 2026-09-25 16:37:43 +07:00

f6ba1e6c4d A CFn may sit in a struct field, a fixed array or a global, and a call through a null one signals NullCall on both backends 2026-09-25 15:26:27 +07:00
b0323606fc spike/ is gone: the x86 and JS surveys and the cells check live in test/, their probes in test/programs as x86-p* and js-p*, and dump.sh in tools/ 2026-09-25 15:14:27 +07:00
610e9fcf9d A parent's handler reads a name and message made in context/temp, whole and good until the frame ends, and the handler-case landing no longer holds a buffer of its own 2026-09-25 14:36:46 +07:00
5646ae148e Merge master; an expression evaluated at a stop runs against a scratch temp arena that is wiped after it, and the program's own temp arena is never rolled back 2026-09-25 14:09:30 +07:00

d864818956 A handler for a parent reads the condition's own name and message or the condition printed with its values, kept in the handler-case's own frame across the unwind, and a frame re-entered through a signal or a C call names where it is 2026-09-25 13:16:35 +07:00

9ba99d7d5b A dev build puts every closure handed to a named call on the collector's heap, since a redefinition can make the callee keep it 2026-09-25 12:55:56 +07:00
bfd176cce9 Merge master: a handler clause runs without its own handler in force, over the condition descriptor, and StaleCall is an Error 2026-09-25 12:50:01 +07:00

23b144178a A dev build's frame records the call it is in, so a backtrace names the call each caller is making and the expression the innermost one stopped at 2026-09-25 12:12:40 +07:00
c6cb018b9f Only a closure that outlives its frame takes a collector environment, and the collector reads a Vec's elements only through a block it knows is live 2026-09-25 12:12:25 +07:00

73dfaacbc8 A condition type may name a parent and a handler for Error catches every built-in error, a signal passes one descriptor carrying its chain, name, sentence and site, and the break loop shows the sentence the runtime wrote 2026-09-25 12:05:13 +07:00

680c12e686 A restart frame carries where its clause is written, its :report sentence and whether a handler-case made it up, and the break loop shows the first two and hides the third 2026-09-25 11:35:12 +07:00

0beafedd14 Dead code is gone, and the daemon says what to fix when a session cannot start or reach its program 2026-09-25 10:45:17 +07:00
39d35f51db A function whose signature changed installs, and a caller compiled against the old one stops on StaleCall at the call
A dev cell carries its body's signature word beside the body, every call through a cell (and every function value taken from one) compares it with the word the site was compiled for, and the session lists the stale callers by file and line on the reply. Both backends, both installers; release builds have neither the word nor the compare.

066fb18940 Every Flan form heads the code it produced in the emitted IR, the x86 listing and both disassembly buffers, and the objects are the same with or without it 2026-09-25 10:34:07 +07:00

ff744120fc A release build's watch is only its value, next-error lets go of a stack that has resumed, and the frame a stop is in is always shown 2026-09-25 08:36:53 +07:00
0653f341d0 A dyn value held in an operand list is rooted while a sibling operand may allocate 2026-09-25 08:36:34 +07:00
9194f918fc An aggregate that reads its own destination sees the old value, on x86 too
x86 built a settling right-hand side straight into its destination, so (set p (P {.a (.b p) .b (.a p)})) wrote .a and read it back for .b. assign now also asks whether the value reads storage the destination lies in, and goes through the temporary when it does. The global-initialiser entry was already closed by startup_plan's Set; the unrooted-temporary entry turns out to be a both-backends rooting gap and stays open for a decision.

57fe91f303 Five records become one, and every citation lands somewhere
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.
