From 9fe249a4525e48a91a98b2b8e7f9e287565aa695 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 24 Oct 2026 10:19:48 +0000 Subject: [PATCH 01/14] Triage the fork's own issues alongside the mirrors The issue-triage skill only classified mirrored upstream issues and left the fork's own issues unlabelled, so a cluster showed only half of what the maintainer tracks. Fork issues (open, not `mirror`, not the board) now get the same cluster and class labels and triage comment, ahead of mirrors within MAX_TRIAGE. They are never closed, parked or retitled in any mode; a mirror that duplicates a fork issue is the one closed. The board shows mirrors and fork issues per cluster in separate columns.

The passthrough declines an edited widget, and also an unchanged one whenever describe prints it imperfectly: on ako/TestApp, re-running `describe page WorkflowCommons.TaskInbox` unchanged rebuilt both data grids, turning the Assignee(s) column's Administration.Account.FullName into System.User.FullName (CE1613) and the row click that opens the task into a NoAction. Rebuilding every pluggable widget of TestApp changed 23 distinct untouched properties. Layout rewrites never loaded the passthrough at all. A declined widget is now patched: it is built a second time from describe's own text for the stored widget, the two builds are compared by property key, and only the properties they disagree on are written, onto the stored Type. A property bound to the widget's own data source is kept while that data source is; any other property naming model elements is kept only while it names what is stored, so a data view moved to another entity still rebinds. Widgets properties always come from the statement's build. Layouts load the passthrough, and the docs say a rewrite keeps a widget's stored schema (use `mxcli widget sync`).

charset=UTF-8 Content-Transfer-Encoding: 8bit `textfilter tf (Attributes: [Name], Placeholder: 'Search name', Adjustable: false)` inside `create page` passed check and exec and stored neither value; describe printed a bare `textfilter tf (Attributes: [Name])`. `alter page … set (placeholder: …, adjustable: …)` on the same widget wrote both. Mirror of mendixlabs/mxcli#1643. Cause: the filters' hand-written definitions map neither key, so both go through the widget engine's explicit-property pass, which looked the authored name up in the template's property keys byte-for-byte. `Adjustable` is not `adjustable`, and `Placeholder:` is a grammar keyword the visitor always stores as "Placeholder", so no spelling reached the template's `placeholder` -- not even the lower-case one describe prints. check's allow-list and its "persisted by the explicit pass" verdict, the mapping pass (lookupProperty) and ALTER's setter (#1069) all fold case; the create writer was the one reader that did not. Fix: explicitPropertyKey resolves the authored name to the template's own key -- exact match first, then a case-only match that is unique and of a kind the pass writes correctly (the set check already calls persisted) -- and the pass writes and scopes by that key. Authored names are iterated sorted, since two spellings can now land on one key. The number and date filters' identical placeholder/adjustable pair and the text/number filters' `delay` are fixed by the same change, as is any unmapped key on any pluggable widget written in a different case. Verified on Mendix 11.13.0: the repro stores the placeholder (identical to the value ALTER writes, ids stripped) and adjustable "false", describe prints both, describe -> exec reports "Unchanged page", raw mx check 0 errors.

On a larger project one rename wrote 147 units in 21 modules (mendixlabs/mxcli#1596). Cause: rewriteConstraint split the constraint with SplitXPathPredicateGroups, which returns the groups without the whitespace between and around them, and re-joined them with "" even when no group changed. The scanner decides whether a unit changed (and counts a rewrite) by comparing that result with the stored string, so the lost separators alone made a write. canon.Reconcile could not elide it: the content really differed. Fix: the splitter gains XPathPredicateGroupSpans, which returns each group's offsets in the string as given. rewriteConstraint returns the stored string itself when no group changed, and otherwise splices each rewritten group back at its offset, copying every byte outside the groups -- so a constraint that does name the attribute keeps its layout and changes only the name token. Tests: byte-identical results for unrelated multi-line constraints (another entity's same-named attribute, a string literal, a longer name sharing the prefix), layout kept on a real rename, a scan test whose control unit is written, and an executor test pinning the reported count. Reverting the fix fails them with the reported symptom ("Updated 3 XPath constraint(s) in 3 document(s)", unrelated units written without line breaks). Verified on Mendix 10.24.24 and 11.13.0 with stored line breaks: before, 4 constraints in 4 units written; after, 2 in 2 (the referencing retrieve and the access rule), line breaks kept, mx check 0 errors.

LINK reports success and links nothing (ako/mxcli#1454) Upstream: mendixlabs/mxcli#1557. Cause: the import read mendixsystem$association.storage_format into a string and compared it with "Column" / "Table". The runtime stores a smallint there: 1 for an FK column on the owner's table, 2 for a junction table. Measured with psql on apps booted by Mendix 10.24.24, 11.12.2, 11.13.0 and 11.14.0, all four store the same values. Neither comparison ever matched, so a column-stored LINK left the FK out of the INSERT, a table-stored LINK skipped the junction insert, and the import printed ": 1 storage" and finished with exit 0. This was not an 11.14 change. LINK had never linked anything against a real database, for either storage kind. Fix: - LookupAssociationInfo decodes storage_format: 1/2, their decimal text, and the model names (any case). Anything else, NULL included, is an error that names the association. - ExecuteImport refuses a LINK whose StorageFormat is neither Column nor Table before it writes the first row, so an unplaceable link can no longer pass silently. - The executor prints a link count for every LINK, zero included. Tests: sql/import_assoc_test.go runs the import pipeline end to end against SQLite fixtures that mirror the measured system rows. With the fix reverted, both storage kinds report "0 linked / 0 missed, want 4 / 1", storage_format 1 decodes to "1", and an unrecognised format imports without error. End to end on 10.24.24, 11.12.2, 11.13.0 and 11.14.0, psql showed 0 FKs and 0 junction rows with the old binary and 4 + 4 with this one. On 11.14 an OQL read through the booted runtime showed the same links.

The same held for every kind RENAME handles as a document: microflow, nanoflow, constant, enumeration, Java action and workflow. Mirror of mendixlabs/mxcli#1545. Cause: the handlers resolved the document among the requested kind only to set a `found` flag, then called RenameDocumentByName(module, old, new), which looked the bare name up again over every unit in the module's containers, whatever its $Type, and rewrote the first match. A Projects$Folder is such a unit, and a FOLDER clause inserts the folder before the document it holds, so the folder won. The reference sweep ran first, so the damage was done either way. Fix: remove the second lookup. The handlers keep the ID of the document they found and call RenameDocument(id, oldName, newName), which replaces RenameDocumentByName on the backend interface and refuses a folder or module unit and a stored Name other than oldName. The document is now renamed before the reference sweep, so a refused rename leaves every reference untouched. Verified on a blank 11.12.2 app with the issue's repro plus nanoflow, constant, enumeration, Java action and workflow: folders keep their names, references follow the documents; the bug-test script goes from 4x CE1613 (main) to 0 errors.

charset=UTF-8 Content-Transfer-Encoding: 8bit `call rest service post '…' (Body: $Payload)` was stored as the custom request template '$Payload' with no parameters, so the request body was the eight characters "$Payload". check, exec and mx check all passed; mx check only warned that $Payload was never used (CW0094). The deprecated `body $Payload` clause built the same statement, and a URL written as an expression (`@M.BaseUrl + '/rates'`) was stored as that text, so the request never reached the server. Upstream: mendixlabs/mxcli#1546. Cause: addRestCallAction turned any URL or custom body that was not a string literal into fb.exprToString(...) and stored that source text as the Microflows$StringTemplate's Text. Fix: an expression is now the template '{1}' with the expression as its one parameter. This is what Studio Pro stores (ako/TestApp Mappings.PostCustomRequestTemplate_2, 11.13.0: Text '{1}' plus one TemplateParameter), and it is the rule log, show message, validation feedback and send email already follow. A string literal is still the template text, including one that spans lines (a SourceExpr around the literal). An expression followed by `with (…)` has no {n} to fill, so it is refused as MDL-REST05. checkRestCallTemplatesStmt makes that decision for both the check pass and exec. declaredMatches normalizes both spellings the same way, so `create or modify` re-run against the stored flow reports the activity unchanged. Describe is unchanged: it prints `Body: template '{1}' with ({1} = $Payload)`, which re-executes to the same document. Verified on an 11.13.0 app. The CW0094 for $Payload is gone and mx check reports 0 errors. Describe -> exec reports "Unchanged microflow", and so does re-running the original `Body: $Payload` spelling. At runtime an echo server received `{"number": "N-1444"}` where the baseline sent "$Payload", and the expression-URL request now arrives (the baseline's never did).
