- stepping over `#endif` accepted a log that is compiled out: `#if 0` / `MGLOG_W(...)` /
`#endif` / `Count(...)` read as logged, and so did a log under `#ifdef
MOBILEGL_VERBOSE_DECLINES` - a Count that counts every time and logs in no shipped build
- the walk now counts the `#endif`s it crosses; a same-indent log met with one outstanding
counts only if every opener enclosing it, reached by continuing upward, is the whole-line
`#if MOBILEGL_BUILD_DISAGGREGATED` (`&& X` is not it). `#if`/`#ifdef`/`#ifndef` with no
`#endif` outstanding is the Count's own guard and is still stepped over, so the column-0
`#if/#endif` fixture stays green; the comment says the walk is fail-open for that one
guard and nothing else
- `#else`/`#elif` stopped the walk only at column 0, as a line of lesser indentation; one at
the Count's own indentation walked straight through to the log above it. PP_STOP now
returns False at any indentation, before the indent test
- two red fixtures, both green on the round-2 audit: "log only under a #if 0 above the
Count" and "log only on the other side of an INDENTED #else at the Count's indentation";
16/16, the tree stays 53 / 53 / 0
- a same-indent `case`/`default:`/`break;`/`return`/`continue;`/`goto`/`throw` line between a
log and a bare Count ends the walk: control cannot flow from that log to the Count, so it
is not the Count's log. A `case 1: MGLOG_W; break; case 2: Count` switch with its labels at
statement indentation, and a log above a `return` with the Count under a same-indent label,
both read as logged before
- `#if`/`#ifdef`/`#ifndef`/`#endif` lines are passed over: a log and its Count that straddle a
`#if MOBILEGL_BUILD_DISAGGREGATED` are one block on both sides of the preprocessor, and the
column-0 line ended the walk for no defect. `#else`/`#elif` still end it - a log on the other
side of one is in a different build, not this one
- four fixtures: same-indent return (red), same-indent switch (red), log across a #else (red,
and red on the previous audit too - it pins that #else still stops), Count under its log
across #if/#endif (green; a false red before). 14/14 fixtures; the tree stays 53 / 53 / 0
- L'"', u'"', U'"' and u8'"': the `'` after an identifier character was taken for a C++14
digit separator, the `"` inside it opened a phantom string, and the rest of the line was
blanked - a site on that line vanished and its row read as NO SITE (fail-closed: a false red)
- CHAR_PREFIX accepts a u8/u/U/L prefix before `'` the way RAW_PREFIX does before `"`, with
a non-identifier character (or the start of the text) in front of it, so a real separator
(0xAB'CD, 1'000) is untouched
- self-test fixture with L'"' and u8'"' ahead of two AT sites on their own lines: rc 0; it
was rc 1 on the previous audit. The tree has no prefixed character literal today (53 / 53 / 0)
- the wire declines audit's LOGGED pattern was unanchored, so a guarded one-liner at the
Count's indentation (`if (g) MGLOG_W("x");`, `g ? MGLOG_W("x") : (void)0;`) counted as
the site's own log and the site read as logged - a decline counted every time but logged
only sometimes, which is the unlogged site the check exists to refuse
- anchored to the statement start; the block walk matches the line, not searches it
- self-test fixture "guarded one-liner log at the Count's indentation" (both shapes) reds
with the NO_LOG sentence; it was green on the previous audit. The tree stays 53 / 53 / 0
Fable review of the B3 rework, should-fix: the audit had no negative
control, so a green run could not say it would have been red. It now takes
--self-test, which writes each inline fixture as a one-file renderer tree in
a temp dir, runs the audit on it and checks both the rc and the line the
audit must print (so a red is red for the fixture's reason):
comment-only site (//) -> rc 1, "has NO SITE"
comment-only site (/* */) -> rc 1, "has NO SITE"
string-literal site -> rc 1, "has NO SITE"
other-branch log -> rc 1, "with no MGLOG_W/E in its own block"
nested-branch log -> rc 1, same
log only in a /* */ comment above -> rc 1, same
nearest log is MGLOG_D -> rc 1, same
good sites (AT form, bare Count under
its own MGLOG_E_ONCE, def row with a
trailing comment) -> rc 0, "0 unlogged, 0 unknown"
8/8, rc 0. Mutants: with the strip disabled 5 of 8 fail (the four
comment/string reds go green and the good fixture's commented row is
lost); with the old 8-line window in place of the block walk 2 of 8 fail
(other-branch, nested-branch). Against the audit as it stood at aab01275,
six of the seven red fixtures passed and the good one failed.
.github/workflows/test.yml: the "Wire declines audit (B3)" step runs
--self-test and then the tree audit, the way the next step runs
trace_cases.py --self-test-transport-matrices before it computes matrices.
Fable review of the B3 rework, should-fix: the 8-lines-above MGLOG_W/E window
was branch-blind - a Count() in `if (x == 2) { ... }` whose only log sat in a
preceding `if (x == 1) { ... }` passed, as did a log in a nested branch just
above. All 12 bare sites in the tree are under their own line today, so this
was a gate hole, not a present defect.
has_own_log() walks upwards from the Count line (still capped at 8 lines):
blank and deeper-indented lines (a log's continuation lines, a nested block)
are passed over, only a line at the Count's own indentation can be its log,
and the first line indented less than the Count - the block's opening, a
sibling's `} else {` - ends the walk.
WireDeclines.def is now read through the same comment/string strip, and ROW
tolerates spaces inside the parentheses: `MGL_WIRE_DECLINE(Name) // note`
used to fail `\)\s*$`, dropping the row, and its real site was then
reported as naming no row.
Tree: 53 rows, 53 with sites, 53 sites, 0 unlogged, rc 0 (unchanged).
Fixtures the previous commit passed and this one reds: other-branch log,
nested-branch log (rc 0 -> 1); a def row with a trailing comment plus its
site (rc 1 -> 0).
Fable review of the B3 rework, must-fix: a row was "sited" by any line the
AT_SITE / COUNT_SITE regex matched, including a // comment, a /* */ block or
a string literal - `// MGL_WIRE_DECLINE_AT(GhostRow, "...");` satisfied the
audit for a row nothing counts, and an MGLOG_W inside a comment above a bare
Count() satisfied the log rule.
wire_declines_audit.py now blanks //...$ (with backslash-newline
continuation), /* ... */, "..." and '...' (raw strings R"d(...)d" and
C++14 digit separators handled) out of each source before any match. Every
character but the newline becomes a space, so the text keeps its length and
line count and each report still cites the real line.
Tree: 53 rows, 53 with sites, 53 sites, 0 unlogged, rc 0 (unchanged).
Fixtures that the previous audit passed and this one reds (rc 1): a
comment-only site (//), a comment-only site (/* */), a string-literal site,
a log only in a /* */ comment above a bare Count. The branch-blind window
and the .def trailing-comment row are the next commit.
The B3 review (ID-P7-34) counted 12 of the 52 rows with no site at all -
TexViewFormat, TexNoApplierRecord, TexRecordDeadOrStale and the nine Shape*
rows were declared and never counted - and ten sites that counted with no (MGLOG_D included)
line, so "a name, a tally and a decline line" did not describe the tree.
- SyncWireTextureShape: all nine Shape* exits now count; the ViewOf exit
and the preserve-flush exit were bare `return false` and are now
MGL_WIRE_DECLINE_AT; the image-flags exit logged only MGLOG_D, which a
Release build compiles away, and is promoted likewise.
- The preserve-copy exit was the one Shape exit with no row: appended as
ShapePreserveCopyFailed (rows are append-only), 53 rows.
- SyncTextureResourceByHandle / UploadPendingWireLevels: the count-only
sites without a log of their own are promoted to MGL_WIRE_DECLINE_AT;
the ones already under a W/E _ONCE line keep that line and gain the count.
- scripts/ci/wire_declines_audit.py: fails on a row with no site, a site
naming no row, or a bare Count() with no MGLOG_W/E within 8 lines above
it. WireDeclineTally.h (the macro's definition) is not a site. Wired into
the job that runs the fatal census.
Audit before: 52 rows, 40 with sites, 10 unlogged under the W/E rule (rc 1). After: 53 rows,
53 with sites, 0 unlogged (rc 0). Forced red (ShapeNoVkFormat made true for
1x1 textures, reverted): Split.Fm.F1WireScenario.VertexIdSampler... fails on
pixels with ShapeNoVkFormat=2 / TexShapeSync=2 in the shutdown tally.
