* test(terminal): pin checkpoint-only cold restore of a large checkpoint
Triaging a report that checkpoint-only cold restore renders blank at every
checkpoint size found no v1.4.156 regression: an A/B of v1.4.155 against
origin/main returned byte-identical ColdRestoreInfo at 1.01, 5.56, 11.30 and
20.61 MiB, all 300 marker lines intact on both refs. Blankness tracks the
meta.endedAt eligibility gate, not size — a cleanly ended session refuses to
cold-restore at any size, which is by design and unchanged between the refs.
What the triage did surface is a coverage gap. #10179's 16MiB checkpoint read
cap sat under what the unbounded writer emits, so a large checkpoint threw,
was swallowed to checkpoint=null, and the pane reopened empty; #10479 raised
the cap but nothing pinned the round trip it had broken. history-reader-memory
covers the bounded reader at its limit, not writer→reader recovery.
Adds that round trip through the real HistoryManager writer and HistoryReader
over a header-only log, and pins the endedAt gate that has now been mistaken
for a size regression twice. Fails at the pre-#10479 cap with the exact
production symptom (detectColdRestore returns null).
* test(terminal): fail loudly when writeSync is unavailable
writeLargeScrollback ignored writeSync's boolean, which is false when
xterm's private _core.writeSync goes away. The size assertions catch that
in the large-checkpoint test (416 bytes vs 16MiB), but the endedAt gate is
size-independent, so that test silently passed on an empty snapshot —
pinning the gate over no scrollback at all.
* test(terminal): cut large-checkpoint fixture peak RSS from 1.2GiB to 800MiB
The filler colored per line, not per cell as its comment claimed, so the
serialized seed only tracked plain-text size and needed 26k buffer rows to
clear 16MiB. The xterm buffer costs rows x cols, which made this single file
raise the whole src/main/daemon/ suite's peak RSS 5.2x (241MiB -> 1244MiB) —
a real OOM risk on CI right after #10299 bounded readers for that reason.
Carrying the bytes in SGR runs instead of rows reaches a larger seed from
5.5k rows: suite peak RSS 1244MiB -> 793MiB, and the margins improve too
(seed 25.16MiB = 1.57x the threshold vs 1.19x before, checkpoint.json
46.1MiB = 2.88x vs 1.20x). Also makes the fixture match its own comment and
be more representative of real colored agent output.
Re-verified all three mutations still fail: cap at 16MiB -> "expected null
not to be null"; endedAt gate deleted -> test 2 fails; writeSync
unavailable -> both fail.
* test(terminal): tighten timeout, reuse prod dir-name helper, dispose first
Review follow-ups, all test-only:
- Import getHistorySessionDirName instead of hand-rolling encodeURIComponent.
Equivalent today, but that helper exists to absorb encoding changes, so the
hand-rolled copy would silently diverge from the writer it is checking.
- Index FILLER_ROWS by its own length so growing the array cannot leave rows
unused.
- 300_000ms -> 60_000ms. The file runs in ~2.8s and vitest's own default is
30s; a 5-minute ceiling turns a hung regression into a stalled job rather
than a failure. 60s keeps Windows headroom.
- Take the snapshot, dispose, then checkpoint, so a throwing checkpoint()
cannot leak the buffer. Note this is memory-neutral, not a saving: peak RSS
is set at getSnapshot(), where the buffer and the serialized strings
coexist, and measured ~800MiB either way.
Mutations re-verified: cap at 16MiB -> "expected null not to be null";
endedAt gate deleted -> test 2 fails; writeSync unavailable -> both fail.
