`TestWatcher_SharedParentRefcount` was deterministically broken on
macOS: `t.TempDir()` lives under `/var` which is a symlink to
`/private/var`, but the watcher canonicalizes paths via
`filepath.EvalSymlinks` before storing them, so the test's `w.dirs[dir]`
lookup missed and returned `0` instead of `2`.
Adds `testutil.TempDirResolved`, a shared helper that returns
`t.TempDir()` with symlinks resolved and falls back to the raw temp dir
on error (Windows-friendly). Migrates the matching inline
`EvalSymlinks(t.TempDir())` callsites in
`agent/agentgit/agentgit_test.go` to use it.

Workspace-agent logs emitted while serving chatd-driven requests were
not correlated with the originating chat, making agent logs hard to
attribute to the corresponding/originating chat.
This adds agent-side chat context middleware that parses `Coder-Chat-Id`
once, enriches agent access logs and structured handler/background logs,
and adds a chatd bridge log when chat headers are attached to an agent
connection.

The slices package provides type-safe generic replacements for the
old typed sort convenience functions. The codebase already uses
slices.Sort in 43 call sites; this finishes the migration for the
remaining 29.
- sort.Strings(x) -> slices.Sort(x)
- sort.Float64s(x) -> slices.Sort(x)
- sort.StringsAreSorted(x) -> slices.IsSorted(x)
## Problem
`TestE2E_WriteFileTriggersGitWatch` and `TestE2E_SubagentAncestorWatch`
flake intermittently in `test-go-race-pg` with:
```
agentgit_test.go:1271: timed out waiting for server message
```
## Root Cause
In `handleWatch()`, `GetPaths(chatID)` was called **before**
`Subscribe(chatID)` on the PathStore. If `AddPaths()` fired between
those two calls:
1. `GetPaths()` returned empty (paths not added yet).
2. `AddPaths()` stored the paths and called `notifySubscribers()` — but
the subscription channel didn't exist yet, so the notification was a
no-op.
3. `Subscribe()` created the channel, but the notification was already
lost.
4. The handler never scanned, and the mock clock never advanced the 30s
fallback ticker → timeout.
Both failing tests connect the WebSocket with an empty PathStore and
immediately call `AddPaths()` from the test goroutine, making them
vulnerable to this scheduling interleaving.
## Fix
Swap the order: call `Subscribe()` first, then `GetPaths()`. This
guarantees:
| `AddPaths` fires... | `Subscribe` sees it? | `GetPaths` sees it? |
Outcome |
|---|---|---|---|
| Before `Subscribe` | No | **Yes** | Picked up by `GetPaths` |
| Between the two calls | **Yes** (queued) | **Yes** | Redundant but
safe (delta dedupes) |
| After `GetPaths` | **Yes** | No | Goroutine handles it |
No window exists where both miss it.
Verified with 10,000 iterations (`-race -count=5000`) — zero failures.
Fixescoder/internal#1389
go-git has bugs in gitignore logic. With more complex gitignores, some
paths that should be ignored aren't. That caused extra, unexpected files
to appear in the git diff panel.
If the git cli isn't available in a workspace, the /git/watch endpoint
will still allow the frontend to connect, but no git changes will ever
be transmitted.
Adds real-time git status watching for workspace agents, so the frontend
can subscribe over WebSocket and show
git file changes in near real-time.
1. Subscription is scoped to a **chat** via `GET
/api/experimental/chats/{chat}/git/watch`.
2. The workspace agent automatically determines which paths to watch
based on tool calls made by the chat (and its ancestor chats).
3. Workspace agent polls subscribed repo working trees on a 30s
interval, on tools calls, and on explicit `refresh` from the client.
4. Scans are rate-limited to at most once per second.
5. Edited paths are tracked **in-memory** inside the workspace agent.
There is no database persistence — state is lost on agent restart. This
will be addresses in a future PR.
6. Messages sent over WebSocket include a full-repo snapshot (unified
diff, branch, origin). A new message is emitted only when the snapshot
changes.
This PR was implemented with AI with me closely controlling what it's
doing. The code follows a plan file that was updated continuously during
implementation. Here's the file if you'd like to see it:
