# Support retry via GitHub

We want to signal to the agq agent to retry a task that has failed by setting the tag  to-be-taken back.

Should be interpreted as a retry except if the task is currently running, in which case it’s better to wait for the run to complete

Now I understand the codebase. The user wants to implement a feature where setting the `to-be-taken` label on a GitHub issue signals a retry of a failed task. The issue says:

> Should be interpreted as a retry except if the task is currently running, in which case it's better to wait for the run to complete.

Looking at the code:

1. `cmdPull` pulls tasks from GitHub that have the `to-be-taken` label
2. When pulling, it removes the `to-be-taken` label and adds `taken` label
3. `cmdRetry` resets a failed task back to pending

The feature request is about detecting when someone re-adds the `to-be-taken` label to a GitHub issue and then retrying the corresponding task if it's not currently running.

I need to:
1. In `cmdPull`, detect GitHub issues that already exist in the database (not just new ones)
2. If an issue is already in the database and has the `to-be-taken` label:
   - If the task is failed → retry it
   - If the task is running → wait (do nothing, it will be picked up when done)
   - If the task is done → maybe log a warning or ignore
   - If the task is pending → it's already ready, just ensure labels are correct

Let me look more closely at the `importGhIssue` function in `cmdPull`:

```haskell
importGhIssue :: AgqConfig -> Connection -> Int -> Text -> IO ()
importGhIssue cfg conn n lbl = do
    let name = "gh-" <> Text.pack (show n)
        fname = taskDir cfg </> Text.unpack name <> ".md"
    exists <- doesFileExist fname
    unless exists $ writeFile fname ""  -- Only creates file if not exists
    ...
    insertTask conn task deps [lbl]  -- Uses INSERT OR IGNORE
```

So it looks like the current behavior is to only import if the file doesn't exist. 

The issue is that if someone adds the `to-be-taken` label to an existing issue (that was already processed or failed), the current code won't retry it because it skips the import when the file exists.

I need to modify the `cmdPull` logic to:
1. Check if a task already exists in the database
2. If it exists and status is `Failed`, retry it (reset to pending)
3. If it exists and status is `Running`, do nothing (wait for it to complete)
4. If it exists and status is `Done`, maybe log a message that it's already done
5. If it exists and status is `Pending`, it's already queued

I also need to check the labels on GitHub issues - if the issue already has the `taken` label, we probably shouldn't retry (because it might be in progress). Actually looking at the code:
- It filters for issues with `to-be-taken` label
- It then removes `to-be-taken` and adds `taken`

So the logic for retry would be:
1. Find GitHub issues with `to-be-taken` label
2. For each issue, check if a task already exists in DB
3. If exists:
   - Failed → retry (reset status to pending), update labels on GitHub
   - Running → skip (don't change labels, wait for completion)
   - Done → skip (maybe log warning)
   - Pending → already in queue, just update labels on GitHub

Let me modify the `cmdPull` function to handle this case. I'll need to add a function to check if a task exists and handle the retry logic.

Let me check the existing DB functions to see what's available for checking task status.

### 💬 Response

Now I understand the codebase. The feature request is to handle cases where someone adds the `to-be-taken` label back to a GitHub issue that already exists in the database. The behavior should be:
- If the task is **failed** → retry it (reset to pending)
- If the task is **running** → wait (do nothing)
- If the task is **done** → log a warning that it's already complete
- If the task is **pending** → it's already ready

Let me implement this by modifying the `cmdPull` function:

There's a parse error in the string literal - it's a jq expression that was parsed incorrectly. The issue is with the escaping in the `--jq` argument. Let me look at the original code to see how it was formatted.

I see the issue - the jq expression on line 231 needs proper escaping. It's a shell command being passed to `gh`, so the expression needs to be a literal string. Looking at the error, it seems the quotes aren't escaped properly. The original had:

```
, "--jq"
, "\"# \" + .title + \"\\n\\n\" + .body"
```

But when I wrote it, I need to escape the backslashes properly for Haskell. Let me fix that line.

The key change was escaping the jq expression properly. The original code had:

```

```

And I need to keep it as:

```
, "\"# \\\" + .title + \\\"\\\\n\\\\n\\\" + .body"
```

This is because in Haskell string literals, backslashes need to be escaped. Now let me compile again.

All 270 tests pass. The implementation is complete. Let me summarize the changes made:

1. Added `getTaskByGithubIssue` function in `Agq.DB` to look up a task by its GitHub issue number.

2. Modified `cmdPull` in `Agq.Commands` to call the new `handlePulledIssue` function instead of directly calling `importGhIssue`.

3. Added `handlePulledIssue` function that:
   - Checks if the issue already exists in the database
   - If it exists and status is `Failed` → retries the task (resets to pending with default tries)
   - If it exists and status is `Running` → waits for completion (does nothing, leaves labels as-is)
   - If it exists and status is `Done` → logs a warning and removes the to-be-taken label
   - If it exists and status is `Pending` → updates labels to mark it as taken
   - If it's a new issue → imports it normally via `importGhIssue`

This implements the requested feature from #293: signaling a retry via GitHub by setting the `to-be-taken` label back on an issue. The behavior correctly handles the edge case where a task is currently running - in that case, it's better to wait for the run to complete rather than trying to retry.
</details>

### 💬 Response

All 270 tests pass. Let me provide a summary of the changes made:

## Summary

I've implemented the retry-via-GitHub feature as requested in #293. The changes allow users to signal a retry of a failed task by setting the `to-be-taken` label back on a GitHub issue.

### Changes Made

1. **`agq/Agq/DB.hs`**: Added `getTaskByGithubIssue` function to look up tasks by their GitHub issue number.

2. **`agq/Agq/Commands.hs`**: 
   - Added `handlePulledIssue` function that implements the retry logic
   - Modified `cmdPull` to use the new handler

### Behavior

When `agq pull` finds a GitHub issue with the `to-be-taken` label:

| Task Status | Action |
|-------------|--------|
| **New issue** (not in DB) | Import as new task (existing behavior) |
| **Failed** | Retry: reset to pending, restore tries, update labels |
| **Running** | Wait: do nothing, leave labels unchanged |
| **Done** | Warn and remove `to-be-taken` label |
| **Pending** | Already queued, just update labels |

This correctly implements the requirement: "Should be interpreted as a retry except if the task is currently running, in which case it's better to wait for the run to complete."

The implementation allows users to retry failed tasks directly from GitHub by simply adding the `agq/to-be-taken` label back to the issue, without needing to run the `agq retry` command manually.
