`core/scripts/load-versions.sh` says it plainly:
The VERSIONS file is the SINGLE SOURCE OF TRUTH for all versions.
DO NOT hardcode version fallbacks in scripts - always source this file.
Two download scripts carry one anyway, and both literals are stale:
core/scripts/linux/download-sherpa-onnx.sh:26
VERSION="${SHERPA_ONNX_VERSION_LINUX:-1.12.18}"
core/scripts/windows/download-sherpa-onnx.bat:24
if not defined SHERPA_ONNX_VERSION_WINDOWS set "...=1.12.23"
Canonical is now 1.13.5 for both platforms, so these were not mirrored through
the 1.13.2 bump or the 1.13.5 one in RunanywhereAI#718. That matters more than usual now:
sherpa_backend.cpp rejects Nemotron 3.5 prompted streaming ASR below 1.13.5, so
a build that quietly picks up 1.12.x produces a runtime that cannot serve a
model the catalog offers.
The Windows path is reachable today. `call :load_versions` returns 1 when
VERSIONS is missing, the caller never checks it, and the next line then invents
1.12.23. On Linux the sourcing failure is caught by `set -e`, but a renamed or
removed key still lands on the literal instead of failing.
Every other platform already fails closed: the macOS and iOS sherpa scripts
error out when the variable is absent, and the three variables on the lines
right below the Linux one use `:?` to do exactly that. This makes those two
match, which also deletes the stale numbers rather than updating them.
📝 WalkthroughWalkthroughThe Linux and Windows Sherpa-ONNX download scripts no longer use fallback versions. Each script now requires its platform-specific version variable and exits when the variable is missing. ChangesSherpa-ONNX version validation
Estimated code review effort: 2 (Simple) | ~5 minutes Merge Risk: 🟡 Moderate · up to The scripts are intended to fail instead of silently selecting an outdated Sherpa version, but inherited environment values can still bypass that safeguard on Linux and Windows. This may produce builds with the wrong runtime version, so the PR needs a targeted fix or explicit owner acceptance before merge.

Heads up on the red Both are red on main too, at I opened #736 with the evidence and a one-line guard. Nothing to do on this PR; every other check here is green. |
What is wrong
core/scripts/load-versions.shstates the rule in its own header:Two download scripts carry one anyway, and both literals are stale:
core/VERSIONScore/scripts/linux/download-sherpa-onnx.sh:261.12.181.13.5core/scripts/windows/download-sherpa-onnx.bat:241.12.231.13.5They were not mirrored through the 1.13.2 bump, nor the 1.13.5 one in #718, so they now sit two minor versions behind.
Why it matters now
engines/sherpa/sherpa_backend.cpprefuses Nemotron 3.5 prompted streaming ASR below 1.13.5, with a comment added in #718 explaining that a 1.13.4 runtime loads the graph but decodes it incorrectly. A build that quietly picks up 1.12.x therefore produces a runtime that cannot serve a model the catalog now offers, and the failure surfaces later as a version-rejection at inference time rather than at build time.The Windows path is reachable today.
:load_versionsdoesif not exist "%VERSIONS_FILE%" exit /b 1, butexit /bonly leaves the subroutine and the caller never checks the result, so a missing VERSIONS file falls straight through to1.12.23.On Linux the missing-file case is caught, since
sourcereturning non-zero tripsset -e. A renamed or removed key is not: the loader succeeds without exporting, and:-supplies the stale literal.What this does
Makes both fail closed, which deletes the stale numbers instead of updating them.
This is what every other platform already does. The macOS and iOS sherpa scripts error out when the variable is absent, and on Linux the three variables on the lines immediately below this one already use
:?:So
VERSIONwas the one variable in that group that guessed.Verification
bash -non the Linux script passes.Normal path, with VERSIONS sourced as the script does:
The behaviour change with the key absent:
I also grepped the tree for
1.12.18and1.12.23to be sure nothing else depended on those values; there are no other references.I could not execute the
.baton this machine, so that half is a read of the control flow rather than something I ran. It is the same one-line shape as the Linux change and matches the file's existingecho [ERROR] ... / exit /b 1idiom used in four other places.No test added: these are build-time download scripts with no harness, and the check that matters is the one above.
