embedding/embedding.go:
- Remove EmbedBatch() (never called in production, test updated to use Embed)
- Remove padID field (written but never read)
embedding/index.go:
- Remove Index.mu mutex (Index is immutable after construction)
skills/skills.go:
- Remove Index.All() (never called)
- Remove Index.Reload() (never called)
virtfs/decl.go:
- Remove RemoveNode() NodeOption (never used)
- Remove RenameNode() NodeOption (never used)
- Remove Alias() NodeOption (aliases set directly on struct)
virtfs/tree.go:
- Remove Tree.Data field (never used)
- Remove Tree.Mount() (never called in production)
- Remove Tree.Child() (never called in production)
- Remove Tree.Children() (never called in production)
- Replace indexOf() with strings.IndexByte
Tests updated to directly manipulate internal children map where needed.
Read, Write, and Rdwr are the three atomic 9P operations:
- Read: non-blocking read
- Write: non-blocking write (fire-and-forget)
- Rdwr: atomic write-then-read (blocking, produces result)
BlockOnce and Stream are special cases of Read.
Rdwr is its own primitive — not a variant of either.
Wire context cancellation through the toolsrv 9P server so that
canceling a CallTool context properly terminates the running tool.
Changes:
- virtfs: Add Close() to File interface with CloseFn for Request handlers
- toolsrv/p9.go: Handle requests concurrently to allow Tclunk during
blocking Twrite; call entry.Close() in handleClunk
- toolsrv/internal/server/proc.go: Check ctx.Done() while waiting for
tool completion in NewProc
- Integration tests for context cancellation chain
The cancellation chain: client cancels ctx → fid.Close() → Tclunk →
handleClunk calls entry.Close() → closeFn cancels reqCtx → NewProc
sees ctx.Done() and returns ctx.Err()
The with* functional options and newTree constructor were private and
only used in two places (builder and tests). Replaced with direct
field assignment on &Tree{} literals. Less abstraction, same behavior.
