fix(dispatch): swallow cfheader InvalidHeaderException when response committed#2756
Conversation
…committed `$header()` is called from `$runOnError` (EventMethods.cfc:113) to set `Content-Type: application/json` on the error response. On Adobe CF 2023 and 2025, the response buffer can already be committed by the time onError fires (any partial output from a view that errored mid-render flushes the buffer at the engine's default threshold). cfheader then throws `InvalidHeaderException: Failed to add HTML header`, which replaces the original exception with the cfheader-failure stack — and every adobe2023/adobe2025 job in the compat matrix returns an HTML error page whose root cause is the secondary header failure, not the real bug. Probe `response.isCommitted()` before calling `cfheader` and return silently when the buffer has already flushed. Callers that need the header guaranteed should set it before producing output; inside onError, swallowing is the right contract because the original exception is what the operator needs to see. A wrapping try/catch is kept as defense-in-depth for engines where the probe misbehaves. The new `$responseCommitted()` helper sits next to `$header()` so other tag wrappers ($content, $location, $cache, ...) can pick it up incrementally as we find further onError-cascade failures.

Wheels Bot — Reviewer A
TL;DR: This PR correctly identifies and addresses the root cause of the Adobe CF 2023/2025 cfheader cascade that was masking original errors in onError. The $responseCommitted() probe is well-structured and the cross-engine fallback is sound. However, the defense-in-depth catch (any e) around cfheader is broader than the stated intent — it silently swallows all cfheader failures even when the response is not committed, breaking the function's existing error-propagation contract for every caller. Requesting changes on that correctness issue plus a missing CHANGELOG entry and absent coverage for the new helper.
Correctness
Silent broad catch changes $header()'s contract for all callers
vendor/wheels/Global.cfc:147-152
try {
cfheader(attributeCollection = "#local.args#");
} catch (any e) {
// Defense-in-depth — if isCommitted() returned false but cfheader
// still rejected the call, don't propagate over the original error.
}The catch wraps the entire cfheader call without any condition on e.type or a re-check of $responseCommitted(). This means any cfheader failure — wrong attribute types, an engine bug, malformed argument combination — is now silently dropped for every caller of $header(), not only the onError path where best-effort semantics are the right contract. Prior to this change, $header() propagated cfheader exceptions faithfully; now it never does.
Suggested fix — re-raise when the response is still uncommitted at throw time:
try {
cfheader(attributeCollection = "#local.args#");
} catch (any e) {
// isCommitted() returned false but cfheader still rejected the call;
// re-check — if now committed, silently swallow so the original error
// in onError is not replaced. If still uncommitted, re-raise so genuine
// caller bugs surface normally.
if (!$responseCommitted()) {
rethrow;
}
}This preserves the defense-in-depth race-window protection for onError (where the response may flip committed between the probe and the cfheader call) while restoring the existing error-propagation contract for all other callers.
Tests
No spec coverage for $responseCommitted() or the committed short-circuit path
vendor/wheels/tests/specs/global/headerSpec.cfc (unchanged by this PR)
The new $responseCommitted() function and the early-return branch in $header() have no test coverage. Testing "response is actually committed" is hard in-process, but the helper itself is trivially testable:
it("$responseCommitted() returns a boolean without throwing", () => {
var result = g.$responseCommitted();
expect(IsBoolean(result)).toBeTrue();
});That spec exercises the GetPageContext().getResponse().isCommitted() call path on every engine and confirms the try/catch fallback (return false) satisfies the declared boolean return type on engines where the probe is unavailable. Without it, any regression in the probe (e.g. a BoxLang API shift) is invisible until a compat-matrix run.

Commit fix(dispatch): swallow cfheader InvalidHeaderException when response committed is well-formed: valid type (fix), optional scope (dispatch), 73-char header, sentence-case, non-empty subject. No issues.
Security
No security concerns. The change only affects header-setting logic inside the framework; there is no user-controlled data entering the new code paths.
Address review feedback on #2756: 1. The defense-in-depth `catch (any e)` around `cfheader` was swallowing every `cfheader` failure, not just the "response committed" race — so genuine caller bugs (bad attribute combos, engine bugs) would no longer propagate. The catch now re-probes `$responseCommitted()` and rethrows when the response is still uncommitted, restoring the pre-#2756 error-propagation contract for every path except the onError cascade we set out to fix. 2. New spec in `headerSpec.cfc` exercises `$responseCommitted()` and asserts the declared `boolean` return type holds on every engine. A future API shift (e.g. a BoxLang `PageContext` change) now fails here in-process instead of going invisible until a weekly compat run. 3. Added the missing CHANGELOG entry under `[Unreleased] > Fixed`, matching the existing prose style for the surrounding entries.

Wheels Bot — Reviewer A
TL;DR: This is the follow-up commit (dfeaed90) addressing all three findings from the prior review. The broad catch (any e) is now correctly narrowed with a re-probe-and-rethrow on the uncommitted path, the missing $responseCommitted() spec has been added, and the CHANGELOG entry is present. The implementation is sound; approving.
Correctness
All three prior findings resolved:
Catch narrowed (was: swallow all failures; now: rethrow when uncommitted)
vendor/wheels/Global.cfc:147-159
try {
cfheader(attributeCollection = "#local.args#");
} catch (any e) {
if (!$responseCommitted()) {
rethrow;
}
}The re-probe inside the catch is the correct shape for the race window: if isCommitted() returned false at the guard but cfheader still threw, we re-check; if the response committed in the intervening microseconds we swallow (best-effort onError contract), otherwise we rethrow so genuine caller bugs surface as before. The logic is tight.
$responseCommitted() implementation
vendor/wheels/Global.cfc:169-175
public boolean function $responseCommitted() {
try {
return GetPageContext().getResponse().isCommitted();
} catch (any e) {
return false;
}
}GetPageContext().getResponse() is standard javax.servlet.jsp.PageContext / javax.servlet.http.HttpServletResponse — available on Adobe CF 2018–2025, Lucee 5/6/7, and BoxLang (which uses a compatible servlet shim). The catch returning false on failure is the conservative default: assume uncommitted, let cfheader proceed, surface any cfheader rejection normally. Correct on all target engines.
Cross-engine
No new cross-engine concerns introduced. public boolean function $responseCommitted() follows the $-prefix + public access convention required for mixin-visible internal helpers (CLAUDE.md § "Private mixin functions are not integrated"). The try/catch wrapper around the Java interop call is sufficient for BoxLang's evolving PageContext surface.
Tests
vendor/wheels/tests/specs/global/headerSpec.cfc:49-64
The new describe("Tests that $responseCommitted()") block exercises both the no-throw contract and the declared boolean return type on every engine in the matrix. The comment in the spec correctly notes why the "response already committed" short-circuit path cannot be tested in-process (flushing the response buffer in a test request would break the runner's own output). The in-process coverage confirms the helper's API contract; the compat-matrix run confirms the Adobe CF cascade fix end-to-end. Satisfactory for this change scope.

After the `$header()` defensive fix in dfeaed9 unmasked the original exception, the adobe2023/adobe2025 compat-matrix logs reveal the real root cause for the chronic Adobe CF compat-matrix failures: the vendored TestBox `JSONReporter.runReport()` calls `BaseReporter.resetHTMLResponse()`, which calls `getPageContextResponse().reset()` — and on Adobe CF 2023/2025 running under Undertow, that throws `IllegalStateException: UT010019: Response already commited` when the response buffer has flushed (populate.cfm or test infrastructure wrote output during setup). The adjacent Lucee-only `resetHTMLHead()` call a few lines up is already wrapped in `try/catch` for the same defensive reason — extend the same shape to the bare `reset()` call. If the reset fails the reporter content still emits, just appended to whatever already flushed; the structured JSON test result is what runner.cfm consumes downstream, so the body shape is preserved. This is the actual blocker for adobe2023/adobe2025 in the weekly compat matrix — every Adobe job has been returning an HTML error page whose cfheader cascade masked this upstream reset failure. With both the dispatch-layer fix (PR #2756) and this reporter fix in place, the Adobe legs should produce structured JSON test results for the first time since the matrix was added.

Wheels Bot — Reviewer A
TL;DR: The new commit (c3e163213) is the final piece of the Adobe CF compat-matrix puzzle: wrapping getPageContextResponse().reset() in BaseReporter with a defensive try/catch so the JSON reporter is not killed by the Undertow IllegalStateException that was surfacing once the $header() cascade was removed. The fix is correct and follows the existing pattern in the same function. Two minor nits on the catch block; no changes requested.
Correctness
Catch block comment over-attributes the failure mode
vendor/wheels/wheelstest/system/reports/BaseReporter.cfc:62–64
} catch ( any e ) {
// Response already committed — skip the reset; the reporter content
// will append to whatever already flushed.
}The comment implies the only possible exception is "response already committed," but catch (any e) catches everything — including getPageContextResponse() itself failing unexpectedly or engine-specific reset() variants throwing for other reasons. In test infrastructure where reset() is best-effort cleanup, this breadth is fine. But the comment should say something like "Response already committed or reset otherwise unavailable — …" to avoid future readers assuming the type is narrower than it is. Not worth blocking on; flag for the next pass or a quick nit fixup.
No logging unlike the adjacent pattern
The Lucee resetHTMLHead() catch three lines above logs to console:
} catch ( any e ) {
writeDump( var = "resetHTMLHead() not supported #e.message#", output = "console" );
}The new reset() catch silently discards the exception with no console trace. In practice this won't matter — the committed-response path is the only known failure mode and the test output still flows — but if a different engine-specific failure ever fires here it will be invisible in the matrix logs. Consider matching the adjacent style:
} catch ( any e ) {
// Response already committed (or reset otherwise unavailable) — reporter
// content will append to whatever already flushed.
writeDump( var = "reset() not available: #e.message#", output = "console" );
}Cross-engine
No new concerns. getPageContextResponse() already handles the Adobe CF double-wrap (getPageContext().getResponse().getResponse()) vs Lucee/BoxLang single-wrap (getPageContext().getResponse()), and both return a standard javax.servlet.http.HttpServletResponse. The CLI guard at resetHTMLResponse():41 ensures the reset() call is never reached when getPageContext is unavailable, so the CLI stub (which only defines setContentType) is never exercised here. The cross-engine shape is correct on all supported engines.
Tests
The BaseReporter change is test infrastructure — a spec testing "reset() swallows when committed" would require committing the response mid-test, which would break the runner itself. No test added and none expected. The existing $responseCommitted() spec in headerSpec.cfc continues to exercise the probe path on every engine in the matrix.

Address Reviewer A round-2 nit on #2756. The `catch (any e)` block in `resetHTMLResponse()` is broader than the previous one-line comment ("Response already committed") suggested — `any` includes any future engine-specific reason `reset()` might be unavailable, not just the known Undertow `UT010019` case. Broaden the comment to reflect actual catch scope (known case + any other reason `reset()` is unavailable) and document why the catch is deliberately silent (no `writeDump`): the adjacent `resetHTMLHead()` `writeDump` is an engine-compat diagnostic — "this Lucee version doesn't ship the method" — which fires once and is informative. The `reset()` failure here is a runtime-state condition (response already flushed) that fires on every successful Adobe CF test run by design, so a `writeDump` would produce noise on every Adobe leg without adding signal.

…lpers The previous two fixes (#2756 dispatch + BaseReporter reset) unblocked TestBox-side bootstrap but the compat-matrix adobe2023 leg on `c3e163213` still fails — only now the cfheader cascade traces to `vendor/wheels/tests/runner.cfm:160`: cfheader(name="Access-Control-Allow-Origin", value="*"); By the time `testBox.run()` returns, Adobe CF (Undertow) has committed the response — individual test specs writing output during the run crossed the engine's buffer threshold and flushed mid-suite. The runner's post-test `cfheader` / `cfcontent` calls then throw `InvalidHeaderException: Failed to add HTML header`. Two changes: 1. `$content()` in `vendor/wheels/Global.cfc` picks up the same `$responseCommitted()` short-circuit and try/catch shape as `$header()`, so callers in error paths or post-flush contexts get best-effort behaviour. Mirrors the existing `$header()` contract that landed in this PR. 2. The eight `cfheader` and four `cfcontent` sites in `runner.cfm` now route through `application.wo.$header()` / `$content()`. The runner already uses `application.wo` elsewhere (`$dbinfo`, etc.) so the wiring is consistent. The status-code header is what CI parsers key on; a committed response keeps whatever status the engine already wrote, and the JSON body still appends below. This should be the third and final layer of the adobe2023/2025 unwind. The same defensive shape is now centralised on the two framework helpers (`$header`, `$content`), so future tag wrappers (`$location`, `$cache`, ...) can adopt it incrementally without re-deriving the isCommitted probe.

Wheels Bot — Reviewer A
TL;DR: The two new commits address both nits from the prior review pass. cc755cb82 broadens the BaseReporter catch-comment to match the actual catch (any e) scope. 024b08d93 adds the $responseCommitted() short-circuit to $content() (mirroring the already-approved $header() shape exactly) and routes all bare cfheader/cfcontent sites in runner.cfm through the defensive framework helpers. A grep of the file confirms no functional bare cfheader or cfcontent calls remain. Approving.
Correctness
All prior findings resolved. Two observations — neither blocks merge:
Commit-message count is off by two on cfheader
024b08d93 commit body says "eight cfheader and four cfcontent sites" in runner.cfm. Counting the diff (and confirmed by post-patch grep): 6 cfheader + 4 cfcontent = 10 sites. The four cfcontent count is correct; cfheader is two short of the claimed eight. The code is correct and complete — every functional call routes through the helper — so this is a historical-record inaccuracy, not a bug.
$content() has no dedicated spec
$header() has an entry in vendor/wheels/tests/specs/global/headerSpec.cfc; the new committed-response short-circuit in $content() does not. The $responseCommitted() helper it delegates to is already covered, and the call-site pattern is identical to $header(), so the risk is low. A follow-up it("$content() returns without throwing when called before any output", ...) in headerSpec.cfc would complete the coverage symmetry.
Cross-engine
$content()'s defensive shape ($responseCommitted() guard + try/catch re-probe) is byte-for-byte identical to the $header() pattern that was reviewed and approved for all supported engines (Lucee 5/6/7, Adobe CF 2018-2025, BoxLang). The cfcontent(attributeCollection = "#local.args#") form uses local.args (plain struct, not arguments) so the Adobe 2023/2025 attributeCollection restriction (CLAUDE.md section Cross-Engine Invariants #10, patched in #2750) does not apply. No new concerns.
Tests
The describe("Tests that $responseCommitted()") block introduced earlier in this PR exercises the boolean-return contract on every engine in the matrix and is unchanged. runner.cfm is test infrastructure; the committed-response path that now routes through the defensive helpers cannot be exercised by an in-process spec without committing the runner's own response buffer. Coverage is adequate given the unchanged $responseCommitted() spec.

`env(required string name, any default = "")` was throwing
`UndefinedElementException: Element DEFAULT is undefined in ARGUMENTS`
on Adobe CF 2023/2025 whenever called with a single positional arg
(`env("KEY")`) — the common case for "this env var must be set."
`default` is a CFML reserved word (switch/case/default), and Adobe
CF's argument-binding leaves the matching arguments-scope key
undefined rather than seeding it from the signature default. Lucee
and BoxLang seed it correctly, so the function appeared to work
everywhere except in the Adobe legs of the compat matrix — where
this single test (`envHelperSpec.cfc:28`) error escaped TestBox's
per-spec catch and propagated all the way up to `runner.cfm`,
poisoning the entire test run with an HTML error page.
Switch to defensive access — `StructKeyExists(arguments, "default")
? arguments.default : ""` — which behaves identically on engines
that seed the default (Lucee/BoxLang return `""` either way) and
fixes the Adobe path. Public `@default` API is unchanged; callers
that pass `default = "X"` keep working.
Surfaced after the three-layer dispatch/test-runner unmasking
(#2756) stopped onError-cascade `cfheader` failures from hiding the
real test exceptions. The compat matrix now actually runs Adobe CF
tests, exposing this one as the next blocker.

Wheels Bot — Reviewer A
TL;DR: The single new commit since the last approval (ac0fead98) is a focused correctness fix for a CFML reserved-word edge case in env(): on Adobe CF 2023/2025, the argument binder leaves arguments.default undefined when the caller omits the second arg because default is a switch/case keyword, causing UndefinedElementException to escape TestBox's per-spec catch and poison the entire Adobe compat-matrix run. The fix is correct and the existing spec at envHelperSpec.cfc:28 exercises the exact path. Two nits — missing CHANGELOG entry, slightly off commit scope — but neither rises to requesting changes.
Correctness
Fix is sound and engine-consistent
vendor/wheels/Global.cfc:605
return StructKeyExists(arguments, "default") ? arguments.default : "";On Lucee/BoxLang: StructKeyExists(arguments, "default") returns true (the binder seeds the default normally), so arguments.default returns "" — same result as before.
On Adobe CF 2023/2025: StructKeyExists returns false (binder skips the reserved-word key), so the fallback "" is returned — matching the declared signature default.
When the caller explicitly passes default="X": StructKeyExists returns true on every engine and arguments.default is "X" — callers that supply the argument are unaffected.
The one latent risk: if a future developer changes the signature default from "" to something else without updating the inline : "" fallback, the two will silently diverge on Adobe CF. A terse comment calling that out would help, but it is not a correctness bug today.

No CHANGELOG entry for the env() fix
CHANGELOG.md [Unreleased] > Fixed received entries for all earlier commits in this PR ($header(), BaseReporter reset(), runner.cfm migration, CHANGELOG count correction) but nothing for ac0fead98. The existing Added entry at line 189 documents the feature introduction; the Adobe CF reserved-word failure and the defensive-access fix belong in Fixed alongside the other compat-matrix unblocks from this PR.

fix(model): env() defaults work on Adobe CF when caller omits fallback |
Nit — model scope is misleading; env() lives in Global.cfc and is not model-specific. Scope global or omitting it would be more accurate. Per CLAUDE.md scope is optional and unrestricted, so this is documentation-only. |
All seven commits carry Signed-off-by: Peter Amiri <peter@alurium.com>. DCO satisfied.
Security
No security surface affected. env() is a read-only helper that resolves environment variable values; the fix only changes how the fallback is accessed, not what data is exposed.
Address Reviewer A nits on ac0fead: 1. Missing CHANGELOG `[Unreleased] > Fixed` entry for the env() Adobe CF reserved-word fix — adds the standard root-cause-chain prose matching the surrounding entries. 2. Latent risk in env(): the inline `""` fallback used on the Adobe CF path must stay in sync with the signature default. A future author changing one without the other would silently diverge between Adobe (defensive path) and Lucee/BoxLang (binder path). Adds a NOTE comment calling that out. The misleading `model` scope on ac0fead is a past-commit comment nit (env() lives in Global.cfc, not a model). CLAUDE.md notes scope is optional and unrestricted, so it's documentation-only — not worth amending and force-pushing for. Using `global` going forward.

Wheels Bot — Reviewer A
TL;DR: The single new commit (da7fbaf45) addresses both nits from the prior review pass: the missing [Unreleased] > Fixed CHANGELOG entry for the env() Adobe CF reserved-word fix is now present, and the sync-guard NOTE comment in env() warns future authors to keep the inline "" fallback in sync with the signature default. Both are correct and complete. The commit message also explains why the misleading model scope on ac0fead98 is not being amended — CLAUDE.md confirms scope is optional and unrestricted, so documenting it forward is the right call. Approving.
Correctness
Both previously flagged issues resolved:
CHANGELOG entry — now present
CHANGELOG.md:40
The new env() entry follows the root-cause-chain prose style of every other entry in ### Fixed: failure mode named, engine specificity called out (Adobe-only, reserved-word binder gap), causal chain explained (only surfaced once the three dispatch/BaseReporter/runner layers stopped masking it), fix described, PR reference included. Content is accurate.
Sync-guard NOTE comment — now present
vendor/wheels/Global.cfc:602–605
// NOTE: the inline `""` fallback below MUST stay in sync with the
// signature default at the top of this function — if you change one,
// change the other, otherwise Adobe CF and Lucee/BoxLang will silently
// diverge for the no-second-arg case.
return StructKeyExists(arguments, "default") ? arguments.default : "";The comment is placed immediately above the divergence risk it describes. Explicit enough that a future author changing the signature default will see it.

B's round 5 critique names three concrete gaps in the current HEAD (b110f95a). I have re-read the diff against each claim. All three are accurate; I concede all three and update my verdict to request-changes.
Conceded points
-
Missing CHANGELOG entry for
$htmlhead(). TheCHANGELOG.mddiff adds entries for$header(),$content(),BaseReporter.resetHTMLResponse(),env(), and$viteResolveAssets(). The$htmlhead()defensive shape (theGlobal.cfclines beginning at thecfhtmlheadhunk, adding the$responseCommitted()early-return andtry/catchrethrow) has no corresponding[Unreleased] > Fixedentry. Every other changed wrapper got one; this omission is inconsistent and leaves the CHANGELOG misleading about the scope ofb110f95a. B is correct. -
Stale
.ai/wheels/cross-engine-compatibility.mdaround the "Future tag wrappers" line. The added section reads:$header() and $content() already adopt this shape. Future tag wrappers ($location, $cache, $htmlhead, $mail, ...) should pick up $responseCommitted() rather than reinventing the probe.But$htmlhead()is patched in this same PR -- thecfhtmlheadhunk inGlobal.cfcapplies the identical defensive shape. Listing it as a pending future item is objectively wrong within the same changeset. The reference-fix sentence on the same page ([#2756] -- adds $responseCommitted() and applies the defensive shape to $header() and $content()) also omits$htmlhead(), compounding the staleness. B is correct. -
No spec for the
$htmlhead()committed-response path.headerSpec.cfcgainsdescribeblocks for$content()(two assertions) and$responseCommitted()(one assertion), but no parallel block for$htmlhead(). The prior review rounds established spec coverage as a gate for each layer before convergence;$htmlhead()skips that gate. B is correct.
Defended points
None. B's three findings are all independently verifiable against the diff lines and none of my prior substantive positions on this SHA are in dispute.
Updated verdict
Request changes: b110f95a needs a CHANGELOG entry for the $htmlhead() defensive shape, a corrected .ai/wheels/cross-engine-compatibility.md (remove $htmlhead from the "future" list and extend the reference-fix sentence), and a describe block in headerSpec.cfc covering the $htmlhead() committed-response short-circuit -- matching the existing $content() spec structure.

Wheels Bot - Reviewer B (round 9) Review 4306679817 is a two-line placeholder stub (body: header-hash-header / line2, zero line comments, COMMENTED state). Like the previous stub submissions, there is no analysis to critique. All three outstanding issues from rounds 4-5 remain unaddressed in the code and unacknowledged by A. Sycophancy Cannot assess - A submitted no content. False positives None to evaluate - no claims were made. Missed issues The three findings from rounds 4-5 are confirmed valid by direct inspection:
Verdict alignment No verdict expressed in the stub. No alignment possible. Convergence Not aligned. This is round 9 of 10 - one more B critique is available before the round cap triggers and the senior advisor takes over. A needs to post a substantive review of the b110f95 diff that either confirms these three findings and signals converged-changes, or makes a credible case they are not actionable. Continued stub submissions will exhaust the cap. |

Wheels Bot — Reviewer B (round 10+, post-terminal convergence)A's review 4306692491 is a substantive concession on all three findings B raised, submitted after the terminal marker. The round count on this SHA exceeded 10 due to duplicate workflow firings, but the loop did not stall on content — it stalled on a series of stub A responses. Review 4306692491 is the first non-stub A submission since B's round 5, and it concedes everything correctly. Converging rather than duplicating the terminal is the right call. SycophancyNone detected. A states explicit concessions with cited evidence for each. False positivesNone detected. A's three conceded points are all accurate:
Missed issuesNone. The three issues above cover the gap between what was implemented and what was documented/tested. No other coverage gaps or cross-engine compat issues surfaced on re-scan.

Wheels Bot -- Reviewer A response (round 9)
B's round 9 critique describes a series of placeholder/stub submissions from A. That is accurate -- those were broken workflow artifacts from a session where the review toolchain was misfiring. A's substantive engagement with B's round 5 findings was submitted in review wheels-bot:review-a-response:2756:b110f95a19f6de481b18d70cf0dce36c78a4c9f9:5 (2026-05-18T01:12:42Z), which conceded all three of B's findings in full. That response and this one constitute A's actual position.
All three findings are confirmed against the diff and stand. The PR is merged, so these require a follow-up.

Contributing to Wheels
A warm welcome and a huge thank you for considering contributing to Wheels!
It's the people in our community who make this framework what it is. Whether you're fixing a bug, adding a feature, improving documentation, or helping in discussions, your effort matters.
These guidelines are here to make the contribution process clear, smooth, and respectful for everyone. They also let you know what you can expect from the maintainers in return — timely responses, thoughtful reviews, and support to help you get your changes merged.

Code of Conduct
We value an open, welcoming, and respectful community. By participating in Wheels projects, you agree to follow our Code of Conduct. This applies to all community spaces, including GitHub, forums, and events.
Developer Certificate of Origin (DCO)
Wheels uses the Developer Certificate of Origin (DCO) for all contributions. The DCO is a lightweight, per-commit attestation that you have the right to submit the work you're contributing. It's a simpler alternative to a Contributor License Agreement (CLA) and is the same model used by the Linux kernel, Docker, and GitLab.
By signing off on a commit, you certify that:
- The contribution was created in whole or in part by you and you have the right to submit it under the open source license indicated in the file; or
- The contribution is based upon previous work that is covered by an appropriate open source license and you have the right under that license to submit that work with modifications; or
- The contribution was provided directly to you by some other person who certified (1), (2), or (3); and you have not modified it.
- You understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information you submit with it) is maintained indefinitely.
Read the full DCO text for the authoritative wording.
How to sign off
Add a Signed-off-by: trailer to every commit. The easiest way is git commit -s, which appends the trailer automatically using your configured user.name and user.email:
git commit -s -m "fix(model): handle null in validatesPresenceOf"The resulting commit message looks like this:
fix(model): handle null in validatesPresenceOf
Signed-off-by: Jane Contributor <jane@example.com>
The name and email must match the identity you use on GitHub. Anonymous or pseudonymous sign-offs are not accepted.
Forgot to sign off?
If you've already pushed a branch without sign-offs, you can amend the last commit:
git commit --amend -s --no-edit
git push --force-with-leaseFor multiple unsigned commits, rebase and add sign-off to each:
git rebase --signoff develop
git push --force-with-leaseEnforcement
The DCO GitHub App runs as a required status check on every PR. It verifies that every commit in the PR carries a valid Signed-off-by: trailer and blocks merge if any are missing. The app comments on the PR with a fixup suggestion when it finds an unsigned commit.
Grandfathering
The DCO is enforced on new PRs only. Commits authored before DCO adoption are grandfathered and do not need to be retroactively signed.
Getting Started
Wheels 3.0 is now maintained in a monorepo at wheels-dev/wheels. This single repository contains the framework core, CLI, documentation, and examples, making it easier for contributors to work across the project.
We welcome contributions via Issues and Pull Requests (PRs). Before you start:
- If it's a security issue, please use our Responsible Disclosure Program — do not post it publicly.
- Search existing Issues and PRs to avoid duplicates.
- If your issue is urgent or blocking, you can leave a polite comment pinging the maintainers.
- If you're new to contributing, check out the Contributing to Wheels Guide for tips and examples.
Development Environment Setup
Quick Start (recommended):
git clone https://github.com/wheels-dev/wheels.git
cd wheels
bash tools/scripts/setup.shThis single command checks prerequisites, starts a MySQL container, installs dependencies via CommandBox, and verifies the environment. Run bash tools/scripts/setup.sh --help for options including --full (all databases) and --docker (no local CommandBox needed).
System Requirements:
- Docker and Docker Compose
- Adobe ColdFusion 2018/2021/2023/2025 OR Lucee 5/6/7
- CommandBox (optional with
--dockermode) - Supported database: H2, Microsoft SQL Server, PostgreSQL, MySQL, Oracle, SQLite
- Git for version control
Initial Setup:
In general, we follow the "fork-and-pull" Git workflow
- Fork the wheels-dev/wheels repository to your own Github account
- Clone the project to your machine
- Run
bash tools/scripts/setup.shto set up your dev environment - Create a branch locally with a succinct but descriptive name
- Commit changes to the branch with
git commit -sto add the required DCO sign-off - Following the formatting and testing guidelines
- Push changes to your fork
- Open a PR in the wheels-dev/wheels repository and follow the PR template so that we can efficiently review the changes.
Issues
Use Issues to:
- Report bugs (include CFML engine version, database type/version, and HTTP server details)
- Request features
- Discuss potential changes before starting a PR
Good First Issues: Look for issues labeled good-first-issue or help-wanted if you're new to the codebase.
If you find an existing Issue that matches your problem:
- Add any extra details or reproduction steps
- Add a reaction to show it affects others, this helps maintainers prioritize
Pull Requests
We welcome PRs of all sizes — from typo fixes to major features. To make reviews smooth:
Branch Naming Conventions:
fix/issue-number-short-description(e.g.,fix/1234-oracle-orm-bug)feature/short-description(e.g.,feature/improved-error-handling)docs/short-description(e.g.,docs/update-installation-guide)
PR Guidelines:
- Keep your PR focused on one thing. If you're fixing a bug, don't also reformat unrelated files.
- Add unit or integration tests when changing functionality.
- Include relevant documentation updates under
/docsif needed. - Follow the repo's formatting guidelines (see
.cfformat.jsonand.editorconfig). - Write clear, descriptive commit messages.
Code Style:
- Follow the project's
.cfformat.jsonconfiguration - Respect the
.editorconfigsettings for consistent formatting - Use meaningful variable and function names
- Add comments for complex logic
Definition of Done:
A feature or enhancement is not complete until all of the following are satisfied:
- Tests -- Unit tests covering happy path, edge cases, and error conditions in
vendor/wheels/tests/specs/ - Framework Docs -- New or updated MDX page under
web/sites/guides/src/content/docs/v4-0-0-snapshot/with a matching sidebar entry - AI Reference Docs -- New or updated file in
.ai/wheels/so AI assistants have accurate context - CLAUDE.md -- Updated if the feature changes model, controller, or view conventions
- CHANGELOG.md -- Entry under the
[Unreleased]section - Test runner passes -- All existing tests still pass (
/wheels/app/tests?format=json)
Bug-fix PRs require tests and a CHANGELOG entry at minimum. Documentation-only PRs are exempt from the test requirement.
If you're making a breaking change or working on core functionality, it's best to open an Issue first to discuss the approach.
Fork-and-Pull Workflow:
- Fork the repo to your GitHub account
- Clone it locally
- Create a descriptive branch name
- Make your changes
- Run tests and check formatting
- Commit with
git commit -sto add the required DCO sign-off - Push to your fork
- Open a PR to
wheels-dev/wheelsand follow the PR template
Review Process:
- Expect initial feedback within 3-5 business days
- Be prepared to make revisions based on maintainer feedback
- PRs require approval from at least one maintainer before merging
Testing
Running Tests:
- Ensure all debugging is turned OFF in your CFML engine
- Navigate to the Wheels Welcome Page in your browser
- In the navigation bar, click "Tests > Run Core Tests"
Test Database Requirements:
- Supported engines: H2, Microsoft SQL Server, PostgreSQL, MySQL, Oracle, SQLite
Writing Tests:
- Use WheelsTest for new test cases
- Place tests in the appropriate
/testsdirectory - Follow existing test patterns and naming conventions
- Include both positive and negative test cases

Wheels Bot
Issues and PRs on this repo are processed by an automated Claude-powered bot
(wheels-bot[bot]). Five stages: triage, cross-framework research,
propose-fix, Reviewer A, Reviewer B. See
docs/contributing/wheels-bot.md for the
full reference, or CLAUDE.md for a quick summary.
To opt a single issue or PR out of bot activity: add the [skip-claude]
label, or include [skip-claude] in the title. The bot will halt all
processing for that issue/PR immediately. Any human comment to the bot
asking it to stop is also honored.
To interpret bot output: every bot comment / review opens with a clear
H2 header (## Wheels Bot — Triage, ## Wheels Bot — Reviewer A, etc.) and
ends with an HTML-comment marker. Bot-authored draft PRs are clearly
labelled and require a human approving review on develop before merge.
Getting Help
Need assistance? Here are your options:
- Community Discussion: Wheels GitHub Discussions
- Documentation: wheels.dev
- Issue Tracker: GitHub Issues
When asking for help:
- Use clear, descriptive titles
- Include your CFML engine and version
- Provide code examples or error messages
- Mention what you've already tried
💡 New to Wheels 3.0? The framework now uses a monorepo architecture with wheelsdi and WheelsTest as core components. The directory structure has been modernized with /app, /public, and /vendor directories. Take time to explore these changes.

fix(model): handle null in validatesPresenceOf
Signed-off-by: Jane Contributor <jane@example.com>
The name and email must match the identity you use on GitHub. Anonymous or pseudonymous sign-offs are not accepted.
Forgot to sign off?
If you've already pushed a branch without sign-offs, you can amend the last commit:
git commit --amend -s --no-edit
git push --force-with-leaseFor multiple unsigned commits, rebase and add sign-off to each:
git rebase --signoff develop
git push --force-with-leaseEnforcement
The DCO GitHub App runs as a required status check on every PR. It verifies that every commit in the PR carries a valid Signed-off-by: trailer and blocks merge if any are missing. The app comments on the PR with a fixup suggestion when it finds an unsigned commit.
Grandfathering
The DCO is enforced on new PRs only. Commits authored before DCO adoption are grandfathered and do not need to be retroactively signed.
Getting Started
Wheels 3.0 is now maintained in a monorepo at wheels-dev/wheels. This single repository contains the framework core, CLI, documentation, and examples, making it easier for contributors to work across the project.
We welcome contributions via Issues and Pull Requests (PRs). Before you start:
- If it's a security issue, please use our Responsible Disclosure Program — do not post it publicly.
- Search existing Issues and PRs to avoid duplicates.
- If your issue is urgent or blocking, you can leave a polite comment pinging the maintainers.
- If you're new to contributing, check out the Contributing to Wheels Guide for tips and examples.
Development Environment Setup
Quick Start (recommended):
git clone https://github.com/wheels-dev/wheels.git
cd wheels
bash tools/scripts/setup.shThis single command checks prerequisites, starts a MySQL container, installs dependencies via CommandBox, and verifies the environment. Run bash tools/scripts/setup.sh --help for options including --full (all databases) and --docker (no local CommandBox needed).
System Requirements:
- Docker and Docker Compose
- Adobe ColdFusion 2018/2021/2023/2025 OR Lucee 5/6/7
- CommandBox (optional with
--dockermode) - Supported database: H2, Microsoft SQL Server, PostgreSQL, MySQL, Oracle, SQLite
- Git for version control
Initial Setup:
In general, we follow the "fork-and-pull" Git workflow
- Fork the wheels-dev/wheels repository to your own Github account
- Clone the project to your machine
- Run
bash tools/scripts/setup.shto set up your dev environment - Create a branch locally with a succinct but descriptive name
- Commit changes to the branch with
git commit -sto add the required DCO sign-off - Following the formatting and testing guidelines
- Push changes to your fork
- Open a PR in the wheels-dev/wheels repository and follow the PR template so that we can efficiently review the changes.
Issues
Use Issues to:
- Report bugs (include CFML engine version, database type/version, and HTTP server details)
- Request features
- Discuss potential changes before starting a PR
Good First Issues: Look for issues labeled good-first-issue or help-wanted if you're new to the codebase.
If you find an existing Issue that matches your problem:
- Add any extra details or reproduction steps
- Add a reaction to show it affects others, this helps maintainers prioritize
Pull Requests
We welcome PRs of all sizes — from typo fixes to major features. To make reviews smooth:
Branch Naming Conventions:
fix/issue-number-short-description(e.g.,fix/1234-oracle-orm-bug)feature/short-description(e.g.,feature/improved-error-handling)docs/short-description(e.g.,docs/update-installation-guide)
PR Guidelines:
- Keep your PR focused on one thing. If you're fixing a bug, don't also reformat unrelated files.
- Add unit or integration tests when changing functionality.
- Include relevant documentation updates under
/docsif needed. - Follow the repo's formatting guidelines (see
.cfformat.jsonand.editorconfig). - Write clear, descriptive commit messages.
Code Style:
- Follow the project's
.cfformat.jsonconfiguration - Respect the
.editorconfigsettings for consistent formatting - Use meaningful variable and function names
- Add comments for complex logic
Definition of Done:
A feature or enhancement is not complete until all of the following are satisfied:
- Tests -- Unit tests covering happy path, edge cases, and error conditions in
vendor/wheels/tests/specs/ - Framework Docs -- New or updated MDX page under
web/sites/guides/src/content/docs/v4-0-0-snapshot/with a matching sidebar entry - AI Reference Docs -- New or updated file in
.ai/wheels/so AI assistants have accurate context - CLAUDE.md -- Updated if the feature changes model, controller, or view conventions
- CHANGELOG.md -- Entry under the
[Unreleased]section - Test runner passes -- All existing tests still pass (
/wheels/app/tests?format=json)
Bug-fix PRs require tests and a CHANGELOG entry at minimum. Documentation-only PRs are exempt from the test requirement.
If you're making a breaking change or working on core functionality, it's best to open an Issue first to discuss the approach.
Fork-and-Pull Workflow:
- Fork the repo to your GitHub account
- Clone it locally
- Create a descriptive branch name
- Make your changes
- Run tests and check formatting
- Commit with
git commit -sto add the required DCO sign-off - Push to your fork
- Open a PR to
wheels-dev/wheelsand follow the PR template
Review Process:
- Expect initial feedback within 3-5 business days
- Be prepared to make revisions based on maintainer feedback
- PRs require approval from at least one maintainer before merging
Testing
Running Tests:
- Ensure all debugging is turned OFF in your CFML engine
- Navigate to the Wheels Welcome Page in your browser
- In the navigation bar, click "Tests > Run Core Tests"
Test Database Requirements:
- Supported engines: H2, Microsoft SQL Server, PostgreSQL, MySQL, Oracle, SQLite
Writing Tests:
- Use WheelsTest for new test cases
- Place tests in the appropriate
/testsdirectory - Follow existing test patterns and naming conventions
- Include both positive and negative test cases

Wheels Bot
Issues and PRs on this repo are processed by an automated Claude-powered bot
(wheels-bot[bot]). Five stages: triage, cross-framework research,
propose-fix, Reviewer A, Reviewer B. See
docs/contributing/wheels-bot.md for the
full reference, or CLAUDE.md for a quick summary.
To opt a single issue or PR out of bot activity: add the [skip-claude]
label, or include [skip-claude] in the title. The bot will halt all
processing for that issue/PR immediately. Any human comment to the bot
asking it to stop is also honored.
To interpret bot output: every bot comment / review opens with a clear
H2 header (## Wheels Bot — Triage, ## Wheels Bot — Reviewer A, etc.) and
ends with an HTML-comment marker. Bot-authored draft PRs are clearly
labelled and require a human approving review on develop before merge.
Getting Help
Need assistance? Here are your options:
- Community Discussion: Wheels GitHub Discussions
- Documentation: wheels.dev
- Issue Tracker: GitHub Issues
When asking for help:
- Use clear, descriptive titles
- Include your CFML engine and version
- Provide code examples or error messages
- Mention what you've already tried
💡 New to Wheels 3.0? The framework now uses a monorepo architecture with wheelsdi and WheelsTest as core components. The directory structure has been modernized with /app, /public, and /vendor directories. Take time to explore these changes.

Wheels Bot — Reviewer A response (round 18)
B's round 18 confirms that convergence on all three findings was established in round 10, and that my round 9 submission (review 4306703429) arrived as a near-simultaneous duplicate of B's converged-changes emission — five seconds after that marker. There is nothing new to dispute or concede; the substantive exchange concluded in round 5 when I accepted all three of B's findings in full.
Conceded points
None new. All three findings were fully conceded in round 5 and reconfirmed in round 9:
- Missing CHANGELOG entry for
$htmlhead()committed-response shape. TheGlobal.cfcdiff adds the$responseCommitted()early-return and try/catch rethrow to$htmlhead(), but no[Unreleased] > Fixedentry exists — inconsistent with every other behavioral layer in this PR ($header(),$content(),BaseReporter.resetHTMLResponse()). - Stale

$htmlhead()spec inheaderSpec.cfc. The diff addsdescribeblocks for$content()and$responseCommitted()but nothing for$htmlhead()'s not-throws / committed-response path, leaving it unspecced against every engine in the matrix.
Defended points
None. B's analysis across all substantive rounds is accurate. The high volume of stub submissions on this SHA were toolchain noise from a misfiring session; they did not represent a genuine position.
Updated verdict
Request changes (follow-up PR required): add a ### Fixed CHANGELOG entry for the $htmlhead() committed-response defensive shape; remove $htmlhead from the future-adopters list in .ai/wheels/cross-engine-compatibility.md and extend the reference-fix sentence to include it; add a describe block for $htmlhead() to vendor/wheels/tests/specs/global/headerSpec.cfc mirroring the $content() not-throws and committed-response coverage. Fully aligned with B's converged-changes position.

Wheels Bot — Reviewer A response (round 19)
B's round 19 adds no new findings and raises no new challenges to my position. This is a confirming round on both sides. The exchange has been converged since round 10; my round 18 submission reconfirmed that alignment and B's round 19 acknowledges it as such. No concessions or defenses are required here.
Conceded points
None new. All three findings were conceded in round 5 and reconfirmed in rounds 9 and 18:

fix(view): $htmlhead defensive shape for committed-response (Adobe CF) |
1 participant
Summary
A layered fix for the Adobe CF 2023/2025 compat-matrix cascade, starting with the
$header()defensive shape that originally motivated this PR. Each layer was uncovered by the previous one once the cfheader cascade stopped masking the real exceptions.Layers landed in this PR (Adobe 2023 progression: 13 fail/error → 3 fail):
$header()probesresponse.isCommitted()before callingcfheaderand short-circuits — stops the original cascade where the secondarycfheaderfailure insideonErrorwas replacing every Adobe CF run's real exception.$content()and$htmlhead()pick up the same defensive shape;$responseCommitted()helper exposes the probe for other tag wrappers to adopt incrementally.BaseReporter.resetHTMLResponse()(vendored TestBox) wraps its bareresponse.reset()in atry/catch— Undertow throwsUT010019: Response already commitedwhen the buffer has flushed mid-suite.vendor/wheels/tests/runner.cfmroutes barecfheader/cfcontentthrough the defensive helpers and pre-sizes the response buffer to 16 MB so the response stays uncommitted long enough for the end-of-suite$header(statusCode = 200|417)to land.headerSpec.cfcafterEachcleanup wraps its barecfheadercalls intry/catchso a committed-response state doesn't surface as an opaque lifecycle error.env(name, defaultValue = "")— second parameter renamed fromdefault(a CFML reserved word Adobe CF refuses to bind, even for positional callers). Legacyenv(name="X", default="Y")named-arg form preserved via the literal-key fallback in the arguments scope.$viteWalkImports(vendor/wheels/view/vite.cfc) — passes the parentrvstruct rather than the innerpreloads/stylesarrays directly (Cross-Engine Invariant Added the cfheader status code message so Search Engines know the site is #6: Adobe CF copies arrays by value out of struct literals, so the walker was mutating discarded copies). Closes five viteSpec failures.ParallelRunner.$collectFailures— same Cross-Engine Invariant Added the cfheader status code message so Search Engines know the site is #6 fix as the vite walker.TestClient.$makeRequest— emits a minimal empty bodycfhttpparamfor POST/PUT/PATCH when the caller passes no body or headers (Adobe CF rejects an emptycfhttpbody block for those verbs).Known follow-up (3 chronic failures, out of scope for this PR)
Three Adobe-CF spec failures remain after the layers above. All three depend on deep CFML scope-shadowing semantics around the
requestscope inside functions that take arequestparameter, and the fixes require interface-level changes that are larger than this PR should carry:publicSpec > processes request to return as struct— Expected status 200, received 404. The chronic outer-response-status bleed: a spec callingprocessRequest()invokes Wheels routing that can throwWheels.RouteNotFoundand call$header(statusCode = 404)via$throwErrorOrShow404Page. The 16 MB buffer pre-size helps but suites exceeding it still bleed the inner 404 into the outer HTTP code. AprocessRequest()-level save/restore is the durable shape. A previous attempt at runner-level suppression (commit66f23b2c, reverted in2414e46d) broke 10 Lucee 7 status-code specs that legitimately depend on inner$header(statusCode = ...)calls being readable via$statusCode().MiddlewarePipelineSpec > RequestId sets request.wheels.requestId— Expected NO to be true.RateLimiterSpec > works in a middleware pipeline with other middleware— Expected NO to be true.Both #2 and #3 hit the same root cause: the middleware interface uses
requestas the parameter name. On Adobe CF, parameters with reserved-scope names shadow the scope strictly —request.wheels.X = ...insidehandle()resolves toarguments.request.wheels.X, not the request scope. Lucee and BoxLang treat the shadowing loosely and write through to the scope. The test reads from the request scope after pipeline.run() and sees nothing. Fixing requires either renaming the parameter in theMiddlewareInterface(breaking change touching all built-in middleware + any user middleware) or rearchitecting the tests to assert on the passed context struct rather than the request scope.Test plan
bash tools/test-local.sh globalcontinues to pass —headerSpec.cfcexercises$header()/$content()/$responseCommitted()before any output, so the defensive probes return false and thecfheader/cfcontentcalls proceed normally.🤖 Generated with Claude Code
