Rebased onto #761 landed the Windows half independently, with the same fail-closed shape and the same reasoning:
That is this PR's argument, reached separately, so I dropped my version of Linux is still unfixed on Same two-versions-behind drift #761 described for Windows, and #761 also documented what that costs on Linux specifically: The remaining diff is one line, and it makes REPOSITORY="${SHERPA_ONNX_REPO_DESKTOP:?SHERPA_ONNX_REPO_DESKTOP is not set}"

Rebased onto 0.20.35. The one red check is not from this diff.
Two further reasons it cannot be this PR: the file changed here is On the change itself, the gap is wider than when I opened this: If |
…version download-sherpa-onnx.sh pinned VERSION to 1.12.18 when SHERPA_ONNX_VERSION_LINUX was missing, while core/VERSIONS says 1.13.5. A VERSIONS file that failed to load would silently fetch a release asset two versions behind, and the sherpa backend then builds as a non-routable stub. Fail closed with :? instead, which is what REPOSITORY, RELEASE_TAG and SOURCE_COMMIT on the next three lines already do. The Windows half of this originally shipped here too; RunanywhereAI#761 landed the same fix independently, so this is now Linux only.

Correcting something I told you in my last comment here. I asserted a behaviour without testing it, and it is not what happens. I said the fallback means the script "does not fail, it quietly downloads 1.12.18 and the build carries on against a Sherpa-ONNX seven versions off the pin". That is wrong. The release tag is pinned separately, so the fallback builds an asset name that does not exist under the tag that does:
The narrower, accurate case for this change:
That is a smaller claim than the one I made, and it is the one I can actually demonstrate. The one-word change still seems right to me on consistency grounds alone, since it is the only one of four adjacent variables not using The stale literal is still real: fallback |
load-versions.sh exports these, so a value left in the environment by an earlier shell satisfies the :? guard even when core/VERSIONS no longer defines the key. That is the same silent stale-version outcome the guard exists to prevent, so clear the four keys this script requires first.
|
Half of this is a real gap in my fix and I have taken it. The other half is already in main. Taken: clearing the keys before loading. You are right that I cleared all four keys the script requires, not just the version, since the repo, tag and commit keys have the identical exposure. Nothing in the repo sets any of them in the environment, so this removes no intended override. Already present: rejecting loader failure in the .bat. The .bat does share the inherited-value hole, since |

Thanks for taking the clear-before-load fix, and for keeping an untested Windows change out of a Linux PR (re: #730 (comment)). Yes please, as its own change: I opened #854 for it. One correction for that PR: Reviewed with help from Claude Code and Codex. |
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.
