feat(libc): accept positional arguments with wide scanf fields on Linux by cocoa55 · Pull Request #11726 · boykopovar/AnyPS5

cocoa55 · 2026-10-27T05:57:18Z

What

On Linux, a scanf-family format that mixes %n$ positions with a 16-bit wide conversion (%ls, %lc, %l[, %S, %C) used to throw NotImplemented ("sscanf positional arguments with a 16-bit wide conversion on Linux"). Only wide formats hit this: narrow-only formats go straight to glibc, which already handles n$.

The in-process scanner (ScanSource) now reads positions itself:

NumberedScanArguments makes one pass over the format and returns the highest n$ position, or 0 when no conversion is numbered. ScanSource reads that many pointers up front, since a va_list can only be read forwards.
Each conversion reads its own n$ with the existing LibcDetail::ArgumentPosition (the printf side uses the same helper), then takes the nth pointer.
A format that mixes numbered and unnumbered assignments throws (scanf positional arguments mixed with unnumbered assignments). POSIX leaves that case undefined, so it is rejected rather than given a meaning. %% and assignment-suppressed %* conversions may still appear next to numbered ones, as POSIX allows.
RequireNoPositionalWideScan and ScansWideInProcess are removed. The callers now test HasGuestWideScan directly.
The _s forms still throw for positional arguments (scanf_s positional arguments), because their size arguments are interleaved with the pointers.

The debt entry is updated. FreeBSD's vfscanf has no $ support (it fails to match at the $), so what the console does here is unverified.

This builds on the fscanf PR (#11724), so until that one merges this PR also shows its commit. Only the last commit belongs to this PR.

Overlap: #9340 and #9087 also edit the wide-field block in ScanSource. Inside that block, this PR changes only the line that fetches the destination pointer (pointerAt(position)). #9340 also edits the scanf entry in docs/dev/debt/libc.md, and #10927 edits the lines around it, but the positional text here is a separate entry. #9340 also changes the wide-scan rejection tests in core/libs/tests/Formatting.cpp next to the %2$ls case removed here, and the #include lines of ScanWideField.cpp. All of these are textual conflicts only, and I'll rebase whichever PR merges second.

Tested

Run by Claude (AI) on Linux (Ubuntu, GCC 13.3), Release build with -DBUILD_TESTING=ON. ryanc2112 also ran it on Arch Linux (GCC 16.2.1), negative control included (see the comments):

guest_formatting_tests: new sscanf/vsscanf cases for reversed positions, a numbered narrow %3$d alongside wide fields, a suppressed %*ls with a numbered %1$n, a short input, mixed numbered/unnumbered formats (%d %1$ls, %1$ls %n) throwing, and vsscanf_s with n$ throwing. The old "%2$ls throws" case is removed.
guest_wide_stream_scan_tests: fscanf with %3$d %1$ls %2$lc.
Negative control: with the src changes reverted, guest_formatting_tests aborts with the old "not implemented" error.
guest_scan_count, guest_wide_formatting, guest_stdio_variadic pass.
Windows not built. The change there only affects sscanf_s/vsscanf_s formats that contain n$, which now throw. Before, the scanner passed the $ to the host as if it were a conversion.

Checklist

fscanf, vfscanf, scanf, vscanf and the _s stream forms threw on %ls, %lc, %l[, %S and %C on Linux. Route those formats through the guest scanner sscanf already uses, reading the stream through StreamSource. The wide field reader now works on any source through Peek and Skip instead of a contiguous buffer: it decides whether to take a character from its lead byte, then consumes the whole UTF-8 sequence, so a rejected character stays in the stream without multi-byte pushback. AI-assisted: yes

Deciding from the lead byte only holds while scanset members are ASCII. Each source now decodes its next character with PeekWide without consuming it, and the field reader skips its bytes only once it takes the character. StreamSource peeks by reading the UTF-8 sequence and pushing it back with ungetc, as the fwscanf stream reader in ScanningWide.cpp already does. Keep TSource::Contiguous. AI-assisted: yes

One point in the argument-position description needs tightening. The code and PR text define what happens when a format mixes numbered assignments (%n$) with unnumbered assignments, and say that this matches glibc. POSIX says those forms cannot be mixed in one format (except %% and assignment-suppressed %* conversions); otherwise the result is undefined: https://pubs.opengroup.org/onlinepubs/000095399/functions/fscanf.html. The added tests use numbered assignments throughout (the unnumbered %*ls case is suppressed), so they do not establish the mixed behavior claimed in the description. Please describe mixed assignment formats as unverified/unsupported, or add a test and document the chosen extension without attributing it to glibc. This is not a correctness blocker for formats that use numbered arguments consistently.

Thanks, good catch. I went with the stricter option: a format that mixes numbered and unnumbered assignments now throws NotImplemented instead of getting a made-up meaning, and the description no longer attributes anything to glibc. %% and %* conversions can still sit next to numbered ones, as POSIX allows. I added tests for %d %1$ls and %1$ls %n throwing, and updated the debt entry and the PR description to match.

MarcZX10 · 2026-10-27T06:41:12Z

The latest update addresses my earlier POSIX concern: mixed numbered and unnumbered assignments now throw, the description is explicit about the exception for %% and suppressed conversions, and tests cover both mixed-assignment orders. The current hosted conventions, eligibility, labels, Ubuntu register-context, ASan relinker, Ubuntu relinker, and macOS x86_64 relinker checks pass; remaining macOS/Windows relinker jobs are pending, while product Linux/Windows jobs are skipped. I also inspected the positional parsing and stream scanner changes in the diff; I could not run the project tests locally in this environment.

One merge-order detail remains upstream in the dependency chain: #11724 now depends on #9087, #9340, and #10927. I found explicit agreement from #9087's author, but no confirmation from #9340's author yet. Since this PR depends on #11724, please make sure that order is agreed with all overlapping PR authors before merging.

Linux run of head d838ff641 (includes #11724), merged onto main c547deaacb (clean merge, local only): SteamOS 3.8 (kernel 6.18.50-valve2), Arch distrobox, GCC 16.2.1, CMake 4.4.4, Ninja, Release, BUILD_TESTING=ON, Ryzen 5 2600.

guest_formatting, guest_wide_stream_scan, guest_scan_count, guest_wide_formatting, guest_stdio_variadic, guest_daemon: 6/6 pass, 3 of 3 runs, on the merge and on plain main.
Negative control: with core/libs/prx/libc/src and include reverted to main and the PR's tests kept, guest_formatting aborts with sscanf positional arguments with a 16-bit wide conversion on Linux not implemented and guest_wide_stream_scan with fscanf 16-bit wide conversion on Linux not implemented, so the new cases exercise the change.

This adds a second Linux toolchain (GCC 16 on Arch) to the Ubuntu GCC 13 run in the description.

AI-assisted: yes (Claude Code)

boykopovar#12530 reads source.Remaining() in the contiguous branch of ScanSource, so dropping the accessor here would break the build whichever of the two lands second, without a textual conflict. AI-assisted: yes

sscanf, vsscanf and the fscanf family threw when a format mixed n$ positions with a 16-bit wide conversion. The in-process scanner now reads the n$ prefix and takes the nth pointer. Formats that mix numbered and unnumbered assignments, which POSIX leaves undefined, and positional arguments in the _s forms still throw. AI-assisted: yes
