acumatica-lint

Free, open-source linter for Acumatica customization projects. Catches publish-time failure modes — silent NullReferenceExceptions, dropped DAC extensions, orphan SiteMap rows, GI catalog exclusions, schema mutations without IF NOT EXISTS guards — before they restart your production app pool.

Want this run automatically on every PR, plus sandbox dry-run before prod, snapshot/rollback with integrity verification, Codex AI review, Slack telemetry, and deploy-window enforcement? → AcuOps

Install

pip install acumatica-lint

Python 3.10+. One dependency (pyyaml for the ISV co-publish allowlist parser). Works on macOS, Linux, and Windows.

Use

Point it at a project.xml:

acumatica-lint Customization/MyPackage/project.xml

With strict mode (additional warnings for best-practice violations):

acumatica-lint --strict Customization/MyPackage/project.xml

ISV authors — enforce a class-name prefix on all <Graph> declarations:

acumatica-lint --isv-prefix AO Customization/MyISV/project.xml

Debug-only DLL-source plugin scan (skips XML/Graph/semantic checks):

acumatica-lint --dll-source-only Customization/MyPackage/project.xml

Exit codes

• 0 — passed (with or without warnings)
• 1 — failed (one or more hard-fail errors)
• 2 — usage error (bad CLI args)

What it catches

acumatica-lint encodes ~60 failure-mode rules from real Acumatica production incidents Studio B has resolved. A non-exhaustive list:

• DAC fields without matching <Sql> ALTER TABLE — auto-column creation has been broken on cloud Acumatica since early 2026. [PXDBx] fields without a corresponding <Sql> ALTER will silently fail at publish.
• Phantom DAC references in <GITable Name> — silently aborts GI processing without an error in the publish log.
• GI Creation Contract — every new OData-exposed GI requires <RolesInGraph Rolename="*" Accessrights="4" ApplicationName="/" /> AND a matching entry in the package's CustomizationPlugin allowlist. Miss either and the GI silently catalog-excludes, returning HTTP 404 from /OData/{tenant}/$metadata.
• SiteMap orphans (ParentID="00000000-...") — invisible in SM205010 (Access Rights by Role), ungrantable, OData 404.
• Modern GI format requirements (24.208+) — GITable.Name must be fully-qualified DAC name; <GIWhere Condition> must use Acumatica's vocabulary ("E ", "NE", "GE", etc., NOT "EQ"); <GIWhere> attribute name is Operation= NOT Operator=; MUIScreen.SubcategoryID must point at tenant-real subcategory, not auto-created system-default.
• <Sql> re-execution warnings — <Sql> scripts are tracked by Name; bumping to _v2 is silently skipped. For logic that must survive every publish, use CustomizationPlugin.PXDatabase.Execute().
• DAC extension fields without <EntityEndpoint> mapping — PUT returns HTTP 200 + echoes value + silent-drops at commit. Three places must match: SQL column, DAC attribute, inline <EntityEndpoint> block.
• C# CustomizationPlugin static checks — banned APIs (WebConfigurationManager, HttpContext); SQL against GI* tables in UpdateDatabase(); SQL against INUnit; INSERT/UPDATE/SELECT column refs on Acumatica system tables outside the allowlist.
• DLL source reference auditing — gap-closer for compiled-DLL plugins: every plugin check runs on every .cs under src/<DllName>/ when project.xml references <File AppRelativePath="Bin\<DllName>.dll" />.
• ISV prefix enforcement — when invoked with --isv-prefix, validates that every <Graph ClassName=> follows your ISV convention.
• Inline <EntityEndpoint> block requirements — must be a top-level child of <Customization> in project.xml; standalone EntityEndpoint_*.xml at zip root is NOT processed.

Every hard-fail check ships an escape-hatch comment marker for audited exceptions:

<!-- REVIEWED: gi-sql-safe       — suppress validate_gi_sql -->
<!-- REVIEWED: inunit-sql-safe   — suppress validate_inunit_sql -->
<!-- REVIEWED: schema-safe       — suppress validate_plugin_sql_column_refs -->

What this linter is NOT

This linter is the deterministic check engine. It runs once, against one project, returns errors and warnings, exits.

It does not:

• Run continuously on every PR
• Push your customization to a sandbox tenant and run an end-to-end test suite before allowing the prod publish
• Take a snapshot of your current customization state with integrity verification before each publish (catching merge=true partial-publish corruption)
• Roll back automatically when a publish fails midway
• Review the C# code in CustomizationPlugin.UpdateDatabase() with AI to flag non-obvious correctness issues a static rule can't catch
• Post :rotating_light: Slack notifications when a publish fails
• Enforce deploy windows (no schema changes during business hours)
• Coordinate co-publishes with ISV packages without inflating the publishBegin page count past Acumatica's ThreadAbortException limit
• Issue + revoke per-VAR license keys with grace periods

All of that is AcuOps — the managed pipeline. $800/mo per Acumatica instance.

Founding partners

AcuOps is selecting 7–10 founding partners locked at $500/mo for the life of subscription in exchange for a published case study + reference availability. We're picking partners across VAR, ISV, in-house mid-market, and enterprise deployment patterns. → Apply

Contributing

Pull requests welcome. New rules should:

1. Reference the originating production incident (AAR date, PR number, or both) in a comment
2. Ship with both a positive example (project.xml snippet that triggers the rule) and a negative example
3. Include an escape-hatch comment marker if the rule may have legitimate exceptions
