feat: MQTT triggers

[dieriba]

Important

Add MQTT triggers to the system, enabling scripts and flows to be triggered by MQTT events, with full backend and frontend integration.

• Behavior:
  • Add MQTT as a new trigger type in build-publish-rh-image.yml, build_windows_worker_.yml, docker-image-rpi4.yml, docker-image.yml, and publish_windows_worker.yml.
  • Update openapi.yaml to include MQTT trigger endpoints for create, update, delete, get, list, exists, set enabled, and test connection.
  • Add MQTT trigger handling in capture.rs and mqtt_triggers.rs.
  • Add MQTT trigger support in +layout.svelte, +page.svelte, and +page.js for UI integration.
• Database:
  • Add mqtt_trigger table and MQTT_CLIENT_VERSION type in 20250207172929_mqtt_trigger.up.sql and 20250207172929_mqtt_trigger.down.sql.
  • Update TRIGGER_KIND type to include 'mqtt' in 20250207173304_add_mqtt_type_value_to_trigger_kind_type.up.sql.
• Models:
  • Add MqttTrigger, NewMqttTrigger, EditMqttTrigger, MqttV3Config, MqttV5Config, SubscribeTopic, and MqttClientVersion in openapi.yaml.
• UI Components:
  • Add MqttTriggersPanel, MqttTriggerEditor, MqttEditorConfigSection, and MqttIcon.svelte for MQTT trigger management.
  • Update DetailPageLayout.svelte, DetailPageTriggerPanel.svelte, and TriggersBadge.svelte to include MQTT triggers.
• Misc:
  • Add rumqttc and serde_repr dependencies in Cargo.toml and Cargo.lock.
  • Update OpenAPI.ts and services.gen.ts for MQTT trigger API integration.

  The MQTT branch in testTriggerConnection is integrated consistently. Ensure that the error handling (using error.body) works as expected if the error object structure changes.
• Reason this comment was not posted:
  Comment did not seem useful. Confidence is useful = 0% <= threshold 50%
  This comment is asking the PR author to ensure that the error handling works as expected if the error object structure changes. This falls under the category of asking the author to double-check or ensure behavior, which is against the rules.

11. frontend/src/lib/components/triggers/TriggersEditor.svelte:65

• Reason this comment was not posted:
  Comment did not seem useful. Confidence is useful = 0% <= threshold 50%
  The comment is asking the PR author to verify the behavior of including 'mqtt' in 'otherValues' for the 'kafka' tab. This falls under asking the author to confirm their intention or ensure behavior, which is against the rules.

12. frontend/src/lib/components/triggers/TriggersWrapper.svelte:75

• Draft comment:
  The new MQTT branch rendering is clear. Confirm that all required bindings (v3_config, v5_config, client_version, subscribe_topics, mqtt_resource_path, client_id) are available from the args.

13. frontend/src/lib/components/triggers/mqtt/MqttEditorConfigSection.svelte:51

• Draft comment:
  The connection setup and topics sections are well structured. Consider adding user feedback (e.g. error messages) if the subscribe_topics array is empty, since isValid is tied to its length.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50%
  The UI already indicates that topics are required through the Required component. The CaptureSection being disabled provides implicit feedback. Adding explicit error messages would be redundant since the required nature is already communicated. This seems like a UI/UX suggestion rather than a critical code issue.
  The comment raises a valid UX concern about providing clear feedback to users. The current Required indicator might be subtle.
  However, this is a UI/styling suggestion about error states, which our rules explicitly say we should not comment on. We should assume the UI/UX decisions were intentional.
  Delete the comment since it relates to UI feedback design rather than code logic issues, and our rules state we should not comment on pure UI/styling changes.

14. frontend/src/lib/components/triggers/mqtt/MqttTriggersPanel.svelte:48

• Draft comment:
  Typo detected: the parameter key 'Left' is capitalized. To maintain a consistent naming convention (as seen in other keys which use lower case), consider renaming it to 'left'.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50%

1. This is in a .sqlx directory which typically contains auto-generated files. 2. The file has a hash in its name, suggesting it's machine-generated. 3. The "Left" capitalization is likely intentional and part of the sqlx library's schema. 4. Modifying auto-generated files is generally not a good practice as they'll be overwritten.
   What if the capitalization actually indicates something important in the sqlx schema? What if other files in the project do use lowercase and this is inconsistent?
   Since this is clearly an auto-generated file (based on directory and hash), any style inconsistencies should be addressed in the generator, not in the generated file.
   Delete this comment as it suggests modifying an auto-generated file, which would be overwritten on the next generation anyway.

• Draft comment:
  There is an inconsistency in casing for the SQL aliasing keyword. In some parts of the query, the alias operator is written as 'AS' while in other parts it is written as 'as'. Consider standardizing the casing (preferably using 'AS' throughout) for improved readability.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 20% vs. threshold = 50%
  While the comment is technically correct about the inconsistency, I need to consider if this is important enough to flag. SQL keywords are case-insensitive, and this is purely a style issue. The code works perfectly fine either way. The comment also provides a concrete suggestion for standardization. However, per the rules, we should avoid purely stylistic comments unless they significantly impact readability or maintainability.
  The inconsistency is minor and doesn't affect functionality. Many SQL style guides don't even specify casing requirements for keywords.
  However, consistency in code style does help with maintainability and readability, and this is a new file where establishing good practices is important.
  While the comment is accurate, it addresses a very minor style issue that doesn't significantly impact code quality. Per the rules about avoiding obvious or unimportant comments, this should be removed.

• Draft comment:
  The alias 'trigger_config!: _' used in the query and describe sections appears to be a typographical error. Please confirm if the extra characters ('!: _') are intentional; if not, consider correcting it to the intended column name (possibly 'trigger_config').
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50%
  The "!: _" syntax looks unusual but appears intentional since it's used consistently in both the query and describe sections. This is likely Rust-specific SQLX syntax for type handling. Without deeper knowledge of SQLX and Rust type system, we shouldn't assume this is a typo. The suggestion to remove it could break type handling.
  I might be missing some context where this syntax is actually incorrect. The consistent usage doesn't guarantee correctness.
  Even if there's a chance it's incorrect, we don't have strong evidence that this is a typo. The consistency suggests intentional usage, and modifying type-related syntax without understanding it is risky.
  Delete this comment. The unusual syntax appears intentional and is likely related to SQLX/Rust type handling. Without strong evidence that it's incorrect, we shouldn't suggest changing it.

24. backend/Cargo.toml:29

• Draft comment:
  It appears that in the workspace members list the entry for windmill-macros is duplicated. The first instance (line 18) correctly uses "./windmill-macros", but the second instance (line 29) is listed as "windmill-macros" without the './' prefix, which is inconsistent.

25. backend/migrations/20250207172929_mqtt_trigger.up.sql:1

• Draft comment:
  Consider revising the comment on line 1 from 'Add up migration script here' to something clearer like 'Add up migration script' or 'Add migration script for up migration' to improve clarity.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50%
  The comment is about a trivial wording change in a comment that doesn't affect functionality. The existing comment is clear enough and follows standard migration comment format. This kind of nitpicking about comment wording doesn't help improve code quality and could be distracting.
  Maybe clearer comments could help future developers better understand the migration's purpose? The suggested wording is marginally more descriptive.
  The existing comment follows standard format and is sufficient. The suggested change doesn't add meaningful clarity and isn't worth the developer's time to change.
  Delete this comment as it suggests a trivial change to a standard migration comment format that doesn't meaningfully improve code quality or clarity.

26. backend/migrations/20250207173304_add_mqtt_type_value_to_trigger_kind_type.down.sql:1

• Draft comment:
  The file is missing a trailing newline. Adding a newline at the end of the file would adhere to POSIX best practices and prevent potential issues with some tools.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50%
  While missing trailing newlines can technically cause issues with some tools, this is a placeholder migration file that will need to be modified anyway. The comment is more about general file formatting than a specific code change. Most modern IDEs and git tools handle this automatically. This seems like an overly pedantic comment for a placeholder file.
  The missing newline could potentially cause merge conflicts or issues with some SQL tools. Maybe this is more important for SQL files specifically?
  The file is clearly a placeholder that will be modified later with actual migration code. Any formatting issues will be addressed when the real content is added.
  Delete the comment. It's too minor of an issue for a placeholder file, and it will likely be resolved naturally when the actual migration code is added.

29. backend/windmill-api/src/mqtt_triggers.rs:445

• Draft comment:
  Typo detected: "occured" should be spelled "occurred" in timeout error messages. Please correct it wherever it appears.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 20% vs. threshold = 50%
  While spelling errors should be fixed, the review rules state not to make comments that are obvious or unimportant. A spelling error in an error message that rarely appears to users is relatively minor. The error message is only shown when there's a timeout connecting to the MQTT broker. Additionally, the comment only suggests fixing one instance when there are multiple instances of the same misspelling.
  The spelling error could affect user experience and code quality. Error messages should be professional and correct. Multiple instances of the same error suggest a systematic issue.
  However, this is a very minor issue that doesn't affect functionality. The error message is rarely seen by users and the misspelling doesn't impede understanding. The rules explicitly say not to make unimportant comments.
  The comment should be deleted as it violates the rule about not making unimportant comments. The spelling error is minor and doesn't significantly impact the code or user experience.

30. backend/windmill-api/src/mqtt_triggers.rs:609

• Draft comment:
  Typo detected: 'commiting' should be corrected to 'committing' in the debug message.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50%
  While the comment is technically correct about the typo, debug messages are not user-facing and only appear in logs when debugging. The typo does not affect functionality. According to the rules, we should not make comments that are obvious or unimportant. A typo in a debug message is very low impact.
  The typo could theoretically make logs slightly harder to search for if someone was specifically searching for "committing". However, the context makes it clear what the message means regardless.
  The extremely minor benefit of fixing this typo does not justify the overhead of a PR comment and review cycle. Debug messages are internal-only and the meaning is clear despite the typo.
  This comment should be deleted as it addresses a trivial typo in debug-only code that does not impact functionality or user experience.

31. backend/windmill-api/src/resources.rs:1237

• Draft comment:
  There's a grammatical/typographical error in the error message string in try_get_resource_from_db_as. The message reads "resource at path :{} do not exist". Consider revising it to something like "resource at path {} does not exist" for clarity.

• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50%
  While the comment is technically correct about the grammar, it's just about a typo in a comment. Comments about documentation or comment text are generally not important enough to include in a PR review. The meaning is still clear despite the minor grammatical error.
  The grammar error could theoretically make the code slightly less professional or harder to maintain. Some teams do care about documentation quality.
  The grammatical error is so minor that it doesn't impact code understanding or maintainability. This kind of nitpick creates noise in PR reviews.
  Delete this comment as it's too minor and doesn't affect code functionality or maintainability.

  Minor typographical suggestion: Consider renaming the property 'collapsable' to 'collapsible' for consistency with common usage.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50%
  While this is technically about changed code since it's a new file, the suggestion is very minor and doesn't affect functionality. The word 'collapsable' is a valid alternative spelling, though 'collapsible' is more common. This seems more like a personal preference than a real issue. The comment doesn't point out a bug or significant code quality issue.
  The spelling 'collapsable' might be consistently used across the codebase, making this change actually harmful to consistency. Also, this could be a prop name defined by the Subsection component that we can't change here.
  Good points - without seeing the Subsection component definition, we can't know if changing this would even be possible. And consistency with existing code is more important than following general English preferences.
  This comment should be deleted as it suggests a minor spelling change that may not even be possible to implement, and could harm codebase consistency.

• Draft comment:
  There is an inconsistency in the casing of 'mqtt'. In some messages it appears as 'mqtt trigger' (lowercase) while in others it's 'MQTT trigger'. For clarity and consistency, consider using 'MQTT' consistently.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50%
  While the comment is technically correct about the inconsistency, this is a relatively minor UI text issue. The rules state not to make purely informative comments and to focus on logic rather than UI. Capitalization in UI text falls more under UI/styling concerns which we're told to assume the author handled correctly.
  The inconsistency could potentially confuse users if they're searching for error messages or documentation. Consistent branding is sometimes important for product quality.
  While consistency is good, this is ultimately a UI text styling issue, not a logic issue. The rules explicitly tell us not to comment on UI/styling changes and to assume the author handled those correctly.
  Delete this comment as it relates to UI text styling rather than logic, and the rules tell us not to comment on UI/styling changes.

• Draft comment:
  There's a slight grammatical typo at line 75: 'Windmill can connect to an MQTT broker and subscribes to specific topics...' should probably use 'subscribe' instead of 'subscribes' since 'Windmill' is singular and the phrase reads better as '...and subscribe to specific topics...'.
• Reason this comment was not posted:
  Comment did not seem useful. Confidence is useful = 40% <= threshold 50%
  The comment is pointing out a grammatical error in the code comments or documentation. While this is not directly related to the functionality of the code, it can be considered useful for maintaining code quality and readability. However, it does not directly relate to the code's functionality or logic, which is the primary focus of the rules. Therefore, it might not be considered useful in the context of this review process.

  Minor stylistic note: the file lacks a newline at the end, which might cause minor issues with some tools. Please add a newline at the end of the file.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50%
  Missing newlines at end of file are typically handled by IDE settings, linters, or git configurations. It's a very minor issue that doesn't affect functionality. Most modern development environments handle this automatically. The comment doesn't suggest any meaningful code changes.
  The missing newline could potentially cause issues with some tools or make git diffs less clean. It's a widely accepted convention to end files with newlines.
  While it's a valid convention, this is exactly the kind of minor, obvious issue that should be handled by automated tools rather than manual review comments. It doesn't warrant human intervention.
  Delete this comment as it's too minor and would typically be handled by automated tooling rather than code review.

• Draft comment:
  It appears that the href attribute in the anchor tag is written as "#{path}". In Svelte, to interpolate a variable into a string, you should use the proper syntax (e.g., href={#${path}}) or concatenation (e.g., href={'#' + path}). Please update this for correct rendering.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50%

1. The current syntax href="#{path}" is actually valid Svelte syntax - Svelte allows interpolation within quoted attributes using {}.
2. The href is only used as an anchor and the actual navigation is handled by the click handler.
3. The suggested changes would work equivalently but don't provide any real benefit.
4. This is a style preference rather than a functional issue.
   The current syntax is valid and works correctly. The comment is suggesting an alternative syntax that provides no functional benefit.
   While the suggested syntax changes are valid alternatives, they don't improve anything and the current code works perfectly fine.
   Delete this comment as it suggests unnecessary changes to valid, working code based purely on style preferences.

When loading an existing MQTT trigger, the error caught is assumed to have a 'body' property. Consider verifying that error.body exists to avoid runtime undefined errors.

Suggested change

	sendUserToast(`Could not load mqtt trigger: ${error.body}`, true)
	sendUserToast(`Could not load mqtt trigger: ${error.body ?? 'unknown error'}`, true)

[ellipsis-dev]

Typo: Replace 'successfuly' with 'successfully' in response descriptions.

Suggested change

	description: successfuly connected to mqtt
	description: successfully connected to mqtt

[ellipsis-dev]

Typo detected: 'succesfully updated mqttq trigger at path {} to status {}'. Consider changing 'succesfully' to 'successfully' and 'mqttq' to 'mqtt'.

Suggested change

	"succesfully updated mqttq trigger at path {} to status {}",
	"successfully updated mqtt trigger at path {} to status {}",

[ellipsis-dev]

The function parameter 'nis_flow' seems inconsistent with the naming used elsewhere (e.g., 'isFlow' in openEdit). Consider renaming it for consistency, perhaps to 'isFlow' or 'is_flow'.

[ellipsis-dev]

For consistency, consider capitalizing 'mqtt' to 'MQTT' in the user-facing message at line 255 (i.e., change "No mqtt triggers" to "No MQTT triggers"). This will match the capitalization used elsewhere in the file.

Suggested change

	<div class="text-center text-sm text-tertiary mt-2"> No mqtt triggers </div>
	<div class="text-center text-sm text-tertiary mt-2"> No MQTT triggers </div>

• Draft comment:
  Consider adding additional context when propagating Base64 decode errors. This would aid debugging if certificate decoding fails.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 30% vs. threshold = 50%
  While adding error context can be helpful for debugging, in this case:

1. The error is already fairly clear - it's a base64 decode error on a client certificate
2. The error gets propagated up and wrapped in a more specific error type (Error::Base64Decode)
3. The error location is obvious from the code structure
4. The suggestion is more of a nice-to-have than fixing a real issue
   The comment does have merit - more specific error messages can help with debugging. And the change is simple and low-risk.
   However, the existing error handling is already adequate. The base64 error type is specific, the context is clear from the code, and it gets wrapped in a custom error type. Additional context would be redundant.
   While not incorrect, this suggestion is more of an optional improvement than fixing a real issue. The existing error handling is sufficient.

  Renaming 'host' to 'broker' improves clarity. Ensure all documentation and API clients are updated to reflect this change.
• Reason this comment was not posted:
  Comment did not seem useful. Confidence is useful = 0% <= threshold 50%
  This comment is asking the PR author to ensure that documentation and API clients are updated, which falls under the rule of not asking the author to ensure things. It doesn't provide a specific code suggestion or point out a specific issue with the code itself.

6. backend/windmill-api/src/mqtt_triggers.rs:308

• Draft comment:
  In get_tls_configuration(), consider handling cases where only a client certificate is provided without a CA certificate. Right now the TLS config is only set if ca_certificate is non-empty.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 20% vs. threshold = 50%
  The comment raises a valid point about a potential edge case. However, in TLS, a CA certificate is typically required to validate the server's certificate - it's not common or recommended to have client certificate authentication without server certificate validation. The current implementation enforcing CA certificate presence is likely intentional as a security measure. Additionally, the rumqttc library may not even support client auth without CA certs.
  I may be making assumptions about the requirements and capabilities of the rumqttc library. There could be valid use cases for client certificates without CA certificates that I'm not considering.
  While there may be edge cases, requiring a CA certificate for TLS connections is a security best practice. The current implementation enforces this in a reasonable way.
  The comment should be deleted as it suggests a change that could weaken security by allowing TLS connections without proper server certificate validation.

7. backend/windmill-api/src/mqtt_triggers.rs:314

• Draft comment:
  Consider adding more contextual information to Base64 decoding errors for the pkcs12_client_certificate to aid in debugging failures.

8. backend/windmill-api/src/mqtt_triggers.rs:344

• Draft comment:
  Defaulting credentials to empty strings when not provided might mask configuration issues. Consider logging a warning or validating if non-empty values were expected.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 20% vs. threshold = 50%
  While the comment raises a valid concern about silently accepting empty credentials, there are several factors to consider:

1. The code is intentionally handling optional credentials this way
2. Empty credentials are a valid use case for MQTT brokers that don't require auth
3. The comment doesn't provide a clear actionable suggestion
4. The current behavior allows flexibility in configuration
   The comment identifies a potential issue with error visibility, but may be overestimating the risk since empty credentials are valid in MQTT.
   Given that empty credentials are a valid MQTT configuration and the code handles optionals explicitly, the current implementation seems reasonable and intentional rather than problematic.
   The comment should be deleted as it suggests changing intentional behavior that is actually valid for MQTT, without providing clear actionable improvements.

9. frontend/src/lib/components/triggers/mqtt/MqttTriggerEditorInner.svelte:109

The 'Create from template' button uses hardcoded hub values in its href. Consider making these values configurable to better accommodate multiple environments.
