Prefer directory-capable adapters when selecting a launch adapter for a
resolved directory program. This keeps Go package directories on dlv in
mixed projects that also expose native-debugger root markers such as a
Makefile, instead of selecting gdb/lldb-dap first and rejecting the
directory during validation.
Added a regression test covering a Go module with both go.mod and
Makefile plus local dlv/gdb adapter shims.
Fixes#2020
The debug tool ran validateLaunchProgram before adapter selection and
rejected any directory program with `launch program resolves to a
directory`, while dlv's default `mode=debug` requires a Go package
path (a directory or .go source file). Every Go-module launch failed:
passing the module dir was rejected outright, and passing the compiled
binary failed at dlv with `not a valid go module`.
- Add `acceptsDirectoryProgram` to DapAdapterConfig/DapResolvedAdapter
and flag dlv in dap/defaults.json.
- In DebugTool.execute(launch), resolve the adapter first, then call
validateLaunchProgram with the resolved adapter — the directory
rejection only fires when the adapter does not advertise the flag.
- Add resolveLaunchOverrides in dap/config.ts: for dlv, derive `mode`
from the program shape (directory or .go file → debug; other file
→ exec). Plumbed through DapLaunchSessionOptions.extraLaunchArguments
and spread between adapter.launchDefaults and the hard-coded launch
fields in session.ts.
- Refresh tests: cover the no-dir-support adapter rejection, dlv on a
package directory keeping mode=debug, and dlv on a binary switching
to mode=exec.
Fixes#2020
Used fs.stat to confirm delayed dlv Unix socket creation before connecting so Linux socket-mode adapters do not race Bun.connect. Added a delayed socket adapter regression test covering the launch path.\n\nFixes #2013
Refactor:
- session.ts: extract mapDebugpyMissingModule helper; replace the duplicated
inline check in launch/attach catch blocks. Add jsdoc on DapStartRequestFailure.settled
documenting per-call ownership and how throwPreferredDapStartError consumes it.
- path-utils.ts: replace the no-op keepOpaqueResourceUri branch with an
OPAQUE_RESOURCE_SCHEMES Set so the structure carries the intent. Functionally
equivalent; new opaque schemes become a one-line Set change.
Tests:
- dap-launch-failures: cover the debugpy stderr -> 'pip install debugpy'
rewrite for launch and attach, plus a negative case (non-debugpy adapter
with the substring in stderr is left untouched).
- dap-launch-failures: model the delayed-launch-failure case the new
settled-race in throwPreferredDapStartError defends against. FakeDapClient
gains optional launchErrorDelayMs/attachErrorDelayMs.
- dap-launch-failures (DebugTool): assert adapter:'debugpy' early-throw
surfaces 'python not found in PATH' on both launch and attach when
selectLaunchAdapter/selectAttachAdapter return null, and the unspecified-adapter
path still falls back to the generic 'No debugger adapter' error.
- find.ts: export validateFindPathInputs and pin the new backslash-escape
semantics (\, no longer trips the comma-joined heuristic) plus the
existing brace-expansion and rejection paths.
- patch.ts: cover the post-write verification error message. The user-facing
ToolError must contain the caller-supplied relative path and not the
absolute resolvedPath (which still lives in the structured context for
log correlation).
- split-internal-url-sel: reword two mcp:// test comments that described a
'peeler refuses' guard that doesn't exist; rename the tests to reflect the
actual opaque-scheme rule.
- browser tool's existing-tab re-nav defaults to waitUntil: 'load' (matching
new-tab path); identical acquireTab() calls no longer hang on dev servers
- patch tool error path uses caller-supplied relative path; absolute
resolvedPath stays in structured context only ($HOME no longer leaks to TUI)
- splitInternalUrlSel keeps mcp:// resource URIs opaque even when they end in
':raw' or '/:1-50' (McpProtocolHandler matches by verbatim URI)
- find tool: timeout signal honored by onMatch; partial results sorted by
mtime desc; backslash-escaped commas skipped in path-list validation
- DAP throwPreferredDapStartError waits up to 50ms for the underlying
launch/attach error instead of one microtask
- debug tool surfaces 'python missing' and 'pip install debugpy' diagnostics
separately when adapter: 'debugpy' is requested
- Preserved launch and attach request failures when configurationDone also fails.
- Handled initial stop-outcome watcher rejections for failed launch and attach attempts.
- Rejected directory-valued debug launch programs before adapter selection and documented the debugpy launch shape.
Fixes#1187
- Reworked #prepareStopOutcome to collect stopped, terminated, and exited event waits before racing them.
- Attached noop rejection handlers to each pending wait promise to prevent unhandled rejection noise after the race settles.
- Returned Promise.race(promises) so stop outcome preparation still waits for the first relevant lifecycle event.
- Extracted `raceWithAbort()` utility to pi-utils package for reuse across projects.
- Replaced local `raceAbort()` implementation with imported `raceWithAbort()` from pi-utils.
- Refactored cleanup timer to use async iterator pattern with `timers.setInterval()` instead of callback-based `setInterval()`.
- Converted `#cleanupIdleSessions()` and `#disposeSession()` from async to synchronous methods with async cleanup loop delegated to `#runCleanupLoop()`.
- Added advanced DAP debugging capabilities including instruction breakpoints, data breakpoints, disassembly, memory introspection, and module inspection.
- Added reverse request handling in DAP client for runInTerminal and startDebugging to support child process debugging.
- Replaced Bun.which() with $which() utility providing flexible cache control and macOS Xcode toolchain fallback.
- Expanded debug tool schema with 20+ new parameters and 11 new action handlers for low-level debugging operations.
- Added instructionPointerReference field to debug session snapshots for enhanced low-level debugging context.
- Added socket-mode transport support for DAP adapters, enabling network socket debuggers like dlv alongside stdio mode.
- Improved extensionless binary debugging to prioritize native debuggers and adapters with root markers.
- Fixed DAP session initialization to subscribe to stop events before launching/attaching, preventing missed stopOnEntry events.
- Refactored session event handling to fetch stack frames outside dispatch loop, eliminating deadlocks and improving responsiveness.
- Enhanced evaluate requests to default to top stopped frame when frameId is not explicitly provided.
