Refreshed against main 0263899e996f26b165aed37f6b5a616dd1d4c6bb; current head af0443d37194a7000804f22c1e71c82cae572dbd retains previous public head 3eca2be06731a86e6dc6a7cf07259dc1378eb149 and main as ancestors. The conflict resolution preserves the topic behavior and current-main ordinary-scan/input-failure handling and fixtures.

The same five fixtures (guest_formatting, guest_scan_count, guest_wide_stream_scan, guest_wide_formatting, guest_crt) pass three times on main and on this head: 15 executions per arm, zero failures/skips. Public-header audit, conventions and whitespace checks pass. These are actual scoped libc/kernel/Ampr owners and selected fixtures with existing frozen ZArchive/zstd providers, not a whole-project build. No new Windows, title-unblock or performance claim.

Raw build/test/JUnit logs, commands, source patches, conflict resolutions and binary hashes, SHA-256 fd8ddb6a38a010916d71698df9cb60011e9800fe14db63baa9f4eca21e6b8e4f (download verified). The batch has 87 successful fixture executions in total; setup failures and corrected final qualification are retained in the archive.

Previous report and contribution template, with historical pins preserved:

Stacked on #12507. It builds on #12507's change to the same lines of ScanSource; review the second commit, 3eca2be067.

What

sscanf_s and vsscanf_s now handle two cases the way the libc.prx that titles ship does.

1. A 0x prefix with no hex digit after it. main handed these fields to the host scanner, which takes 0x as 0 and counts a successful conversion. The titles fail the conversion and store nothing:

field	titles' result
%x, %X, %i or %p where the input or the width ends right after the x, with no sign ("0x", " 0X", "0x1" with %2x)	input failure: EOF, or the count so far after an earlier conversion
the same with a non-hex character after the x ("0xg"), or with a sign ("-0x", "-0x1" with %3x)	matching failure
floating (%a, %e, %f, %g)	needs a hex digit, or . and a hex digit, within the width ("0x.8" is 0.5); anything else is a matching failure, never EOF

%d, %o and %u read the 0 and are unchanged. The check runs before the field reaches the host scanner.

2. errno for floating fields. UCRT sets ERANGE when %e of 1e40 overflows a float, and when %a of 0x1p200 does. The titles set it only when a decimal field overflows, or underflows to 0, as a long double, whatever the destination width; otherwise errno is left alone. This is the same rule #12514 measured for swscanf. Examples:

• %Le of 1e5000 and %Lg of 1e-5000 set ERANGE;
• %le of 1e400 and %La of 0x1p20000 don't.

errno is now decided from the scanned text with strtold.

Limits (new debt entry):

• The stream forms (fscanf_s, scanf_s and their v forms) can only look one character ahead, so they keep the old behaviour.
• On a host whose long double is double (macOS on ARM), a decimal field beyond double range sets ERANGE.

Tested

Windows 11 Enterprise 10.0.22621, Ryzen 9 5950X, WinLibs GCC 15.2.0 UCRT r7, Ninja, Release, BUILD_TESTING=ON, head 3eca2be067 (on #12507, base 6793a72475).

• Native comparison: a scratch loader runs the decrypted libc.prx of PPSA07923 and PPSA05916 and calls their sscanf_s by NID.
  • Random: 200,000 random numeric conversions per title, comparing the result, stored bytes, %n and errno. main (470a562903) has 136 differences in PPSA07923: 78 0x failures, 37 float errno cases, fix(libc): wrap narrow integers in sscanf_s as titles' libc.prx does #12507's 20 wrap cases and the NaN case below. This PR has 1 per title: a %5Lf of "-naNXf" that differs past the 8 bytes the probe prints, most likely the NaN's sign. That is a separate issue and isn't touched here.
  • Targeted: 33 prefix cases (signs, widths, %i, %p, suppressed fields, a failure after an earlier conversion) and 15 range cases (%e, %le, %Le, %a, %La, %Lg, 64-bit integer overflow). 0 differences in both titles.
• Unit tests: guest_formatting gains these cases. With fix(libc): wrap narrow integers in sscanf_s as titles' libc.prx does #12507's Formatting.cpp and the new tests, guest_formatting fails.
• Regression set: guest_formatting, guest_stdio_variadic, guest_scan_count, guest_wide_stream_scan, guest_wide_formatting, file_streams and the five guest_standard_streams* tests pass 3/3. Conventions pass.
• Merges: git merge-tree merges this head cleanly with fix(libc): end sscanf and vsscanf at a q length on Linux and macOS #11852, fix(libc): match bundled narrow scansets and scan directive parsing #12428 and fix(libc): read wide scanf fields byte by byte, as titles' libc.prx does #12468, the other open PRs that touch Formatting.cpp.
• Linux/macOS: covered by CI only; I didn't run them locally.

Integration and landing order — 2026-10-29

For my own PRs, the landing order is #12507 → #12530 → #12468. #12468 now retains StringSource::Remaining(), which #12530 uses twice. A private tree exactly matching the merge of #12468 accessor fix a84100962ceb61a1646c04aa62bdcc254c8cec01 and this PR at 3eca2be06731a86e6dc6a7cf07259dc1378eb149 builds and passes five focused Linux suites three times (15 checks). Removing the accessor produces the expected compile errors at those two calls; restoration passes all15 checks and restores identical libc bytes. The private combined source was not published.

The final #12468 head 068725777be07527eda51e086d8850500b7b8707 additionally integrates main157b and passes the same15 checks, with both formatting translation units passing MinGW cross syntax checks. This does not constitute new Windows runtime testing or external #11724 author agreement.

Reviewed — looks good

The second stacked commit’s prefix checks and string-scan errno handling match the measured behavior described in the PR, and I found no blocking issue in that incremental diff.

What I ran

Reviewed commit 3eca2be06731a86e6dc6a7cf07259dc1378eb149 on parent PR #12507 head 0b3eb0b3e53a8faa1f01fd01a6de4061247ab308. The cumulative head merges cleanly onto current main f21ef7c99c5af648c5a41bddb18ce118b8e60c46. Environment: Debian 12 x86_64. I checked the incremental diff, merge tree, and whitespace; I did not build or execute the formatting tests locally.

Findings

Blocking

None found in the incremental change.

Non-blocking

The focused tests and title comparisons are author-reported. The hosted Windows job skipped CTest; Linux was skipped and macOS checks were pending when checked.

Sources

• Prefix and range handling at the reviewed commit
• Focused tests at the reviewed commit
• Documented behavior and platform limitation at the reviewed commit

Not verified

I did not independently build/run the tests, use the title comparison loader, test on macOS or a console, or rerun the author’s random/targeted probes.

To get this to a good state

No follow-up is needed for this incremental review. If the commit changes, I will re-review its diff and rerun the merge and whitespace checks.

@JJenkx the content of this PR looks right to me; one thing to sequence before it and #12468 can both land.

#12468 deletes StringSource::Remaining() (its wide branch was the last user: - const char* Remaining() const { return position; } in Formatting.cpp). This PR adds two new calls to it, in the 0x prefix check (CheckHexPrefix(source.Remaining(), width, floating)) and in the floating errno test (DecimalOutOfRange(std::string(source.Remaining(), ...))). git merge-tree merges the two cleanly because the edits are in different hunks, but the merged Formatting.cpp then has two calls and no definition, so the StringSource instantiation of ScanSource does not compile. Each PR's own CI is green, so nothing would flag it until the second one is rebased onto the first.

Whichever of #12468 and this PR lands second needs Remaining() kept or re-added. The simplest is to keep Remaining() in #12468 (it is a one-line accessor and this PR uses it), or to say here that you will re-add it when you rebase. This PR is also stacked on #12507, which needs to land first.

[JJenkx]

A merge-order note from a local integration run. I merged this stack (#12507, this PR, #12532) with my #12428 and #12468 on main 319621ba2e, plus a local experiment that routes Windows vsscanf through ScanSource.

• Textual conflict with fix(libc): read wide scanf fields byte by byte, as titles' libc.prx does #12468 in Formatting.cpp, two spots:

  • fix(libc): read wide scanf fields byte by byte, as titles' libc.prx does #12468 removes the #ifndef _WIN32 around the wide-field branch, where fix(libc): match bundled narrow scansets and scan directive parsing #12428 adds a line after its #endif.
  • Both PRs change the Windows vsscanf dispatch.

  Both resolve mechanically.

• Semantic dependency: fix(libc): read wide scanf fields byte by byte, as titles' libc.prx does #12468 sits on cocoa55's feat(libc): read 16-bit wide fields in fscanf on Linux #11724, which removes StringSource::Remaining(). This PR's 0x pre-check and errno text use it. Whichever of the two lands second has to restore the accessor, const char* Remaining() const { return position; }, or it won't compile.

With both handled, the combined tree passes guest_formatting, guest_stdio_variadic, guest_scan_count, guest_wide_stream_scan, guest_wide_formatting, guest_wide_conversion, guest_strings, file_streams, guest_json, guest_safe_errors and the guest_standard_streams* tests 3/3 on Windows.

Against the libc.prx of PPSA07923 and PPSA05916, plain sscanf and sscanf_s then differ on:

• 0 of 200,000 random numeric conversions;
• 0 cases in every scanset, string and wide-field probe;
• 2 of 100,000 random scansets. Those two have a format literal byte from 0x80 up after the set, which the titles fail to match.

Refreshed onto main e772fb25cc (merge 2b8cca92ff). The conflict in core/libs/prx/libc/src/Formatting.cpp came from main's narrow-integer change to the neighbouring source.Scan(...) line. This PR's block next to it is kept unchanged, and every line the PR adds is present in the merge.

Windows, WinLibs GCC 15.2 UCRT, Release:

• Formatting tests: guest_formatting and guest_wide_formatting pass in 3 of 3 runs, none skipped.
• Negative control: with main's Formatting.cpp, one of the two fails ("Formatting check failed").
• Conventions: tools/check_conventions.py passes.

AI-assisted: yes.

Linux check of exact head 2b8cca92ff. Arch Linux 7.2.11, GCC 16.2.1, Release, BUILD_TESTING=ON.

guest_formatting and guest_wide_formatting pass in 3 of 3 runs each (ctest --repeat until-fail:3), none skipped. These are the tests the Windows refresh ran.

AI-assisted: yes

agc_driver_bda_reads_shadowed_results_per_build: skipped, the device reports watched host memory written when it imports or reads it
agc_driver_copied_writer_label_order: skipped, the device reports a minStorageBufferOffsetAlignment of 4, so the dispatch binds its record at +0x1004 in place and nothing is written back; the test needs an alignment above 4
agc_driver_copied_writer_label_order_drain: skipped, the device reports a minStorageBufferOffsetAlignment of 4, so the dispatch binds its record at +0x1004 in place and nothing is written back; the test needs an alignment above 4
agc_driver_float16_unused_nan_payloads: skipped, the device has no native f16 conversions with RTE rounding and kept f16 denormals
agc_driver_gcn_display_present: skipped, no display: Vulkan support is either not configured in SDL or not available in current SDL video driver (offscreen) or platform
agc_driver_image_table_vouched_lookups: skipped, the device reports 4 of 4 host-imported pages written after a GPU read, so a watched imported table cannot be vouched for
agc_driver_linear_target_direct_write_completion: skipped, the device does not keep host imports write-watched, so no completion stamp over the target is tracked
agc_driver_ngg_vertex_wave_reduction: skipped, s3 describes a 32-lane wave only on 32-lane subgroups, and the device has 64 lanes
agc_driver_recorded_draw_staging: skipped, the device does not keep host imports write-watched, so the target is never resident

Re-checked against current main 6185bdcfc: the Formatting.cpp changes that landed since the last review don't touch the 0x prefix check or the floating errno path, and #12468 (merged) kept StringSource::Remaining(), so both new calls compile; merged.
