- tick_batch(0) now returns empty instead of silently draining one line
- has_live_tail avoids Vec allocation via field comparison
- Convert 15 sync-only controller tests from tokio::test to #[test]
Address reviewer concerns about self-referential test coverage:
- Column-metrics: 6 tests for TableColumnKind classification,
preferred_column_floor caps, and next_column_to_shrink priority.
- Spillover detection: 6 tests for is_spillover_row covering each
heuristic branch and negative cases.
Add module-level, type-level, and function-level documentation across
the table rendering pipeline: table_detect, width, markdown,
markdown_render, and streaming/controller. Separate spillover lines
from table grid output via RenderedTableLines so spillover prose
routes through normal word wrapping instead of bypassing it.
Add module, type, and function-level doc comments across the table
rendering change. Fix typos ("taht", "mirros", "stabe", "durin").
Expand streaming controller module docs to cover holdback and resize
handling. Document width allocation, spillover detection, consolidation,
and prewrapped line rendering contracts. No runtime behavior changes
in documentation edits; also includes extracted draw helpers in app.rs
and a fence-detection fix in markdown.rs.
Wire the Unicode box-drawing table renderer into the live streaming
path with holdback-aware commit logic, post-stream cell consolidation,
and debounced resize reflow.
Key additions:
- StreamCore: shared bookkeeping deduplicating Stream/PlanStreamController
- Table holdback: fence-aware state machine keeps buffer mutable during table detection
- AgentMarkdownCell: stores raw markdown source, re-renders at any width on demand
- ConsolidateAgentMessage: backward-walk replaces streamed cells with single consolidated cell
- Resize reflow: debounced (75ms) re-render of all transcript cells after terminal resize
Add proper table rendering to the markdown renderer using Unicode
box-drawing characters (┌─┬┐│├─┼┤└─┴┘) instead of raw pipe syntax.
Supports column alignment, cell wrapping at narrow widths, tables
inside blockquotes, escaped pipes, and styled inline content.
Addresses #16622
Problem: bare local file links in TUI markdown render percent-encoded
path bytes literally, unlike file:// links.
Solution: decode bare path targets before local-path expansion and add
regression coverage for spaces and Unicode.
Problem: The resume picker used awkward "Created at" and "Updated at"
headers, and its relative timestamps changed while navigating because
they were recomputed on each redraw.
Solution: Rename the headers to "Created" and "Updated", and anchor
relative timestamp formatting to the picker load time so the displayed
ages stay stable while browsing.
Addresses #16781
Problem: `codex exec --ephemeral` backfilled empty `turn/completed`
items with `thread/read(includeTurns=true)`, which app-server rejects
for ephemeral threads.
This is a regression introduced in the recent conversion of "exec" to
use app server rather than call the core directly.
Solution: Skip turn-item backfill for ephemeral exec threads while
preserving the existing recovery path for non-ephemeral sessions.
Addresses #16832
Problem: After `/fast on`, the TUI omitted an explicit service-tier
clear on later turns, so `/fast off` left app-server sessions stuck on
`priority` until restart.
Solution: Always submit the current service tier with user turns,
including an explicit clear when Fast mode is off, and add a regression
test for the `/fast on` -> `/fast off` flow.
Addresses #16584
Problem: TUI word-wise cursor movement treated entire CJK runs as a
single word, so Option/Alt+Left and Right skipped too far when editing
East Asian text.
Solution: Use Unicode word-boundary segments within each non-whitespace
run so CJK text advances one segment at a time while preserving
separator and delete-word behavior, and add regression coverage for CJK
and mixed-script navigation.
Testing: Manually tested solution by pasting text that includes CJK
characters into the composer and confirmed that keyboard navigation
worked correctly (after confirming it didn't prior to the change).
This adds end-to-end coverage for `responses-api-proxy` request dumps
when Codex spawns a subagent and validates that the `x-codex-window-id`
and `x-openai-subagent` are properly set.
Addresses #13614
Problem: `codex exec --help` implied that `--full-auto` also changed
exec approval mode, even though non-interactive exec stays headless and
does not support interactive approval prompts.
Solution: clarify the `--full-auto` help text so it only describes the
sandbox behavior it actually enables for `codex exec`.
Addresses #15535
Problem: `codex exec --help` advertised a second positional `[COMMAND]`
even though `exec` only accepts a prompt or a subcommand.
Solution: Override the `exec` usage string so the help output shows the
two supported invocation forms instead of the phantom positional.
Problem: `rejects_escalated_permissions_when_policy_not_on_request`
retried a real shell command after asserting the escalation rejection,
so Windows CI could fail on command startup timing instead of approval
behavior.
Solution: Keep the rejection assertion, verify no turn permissions were
granted, and assert through exec-policy evaluation that the same command
would be allowed without escalation instead of timing a subprocess.
This test was flaking on Windows.
Problem: The Windows CI test for turn metadata compared git remote URLs
byte-for-byte even though equivalent remotes can be formatted
differently across Git code paths.
Solution: Normalize the expected and actual origin URLs in the test by
trimming whitespace, removing a trailing slash, and stripping a trailing
.git suffix before comparing.
## Why
Bazel CI had two independent Windows issues:
- The workflow saved/restored `~/.cache/bazel-repo-cache`, but
`.bazelrc` configured `common:ci-windows
--repository_cache=D:/a/.cache/bazel-repo-cache`, so `actions/cache` and
Bazel could point at different directories.
- The Windows `Bazel clippy` job passed the full explicit target list
from `//codex-rs/...`, but some of those explicit targets are
intentionally incompatible with `//:local_windows`.
`run-argument-comment-lint-bazel.sh` already handles that with
`--skip_incompatible_explicit_targets`; the clippy workflow path did
not.
I also tried switching the workflow cache path to
`D:\a\.cache\bazel-repo-cache`, but the Windows clippy job repeatedly
failed with `Failed to restore: Cache service responded with 400`, so
the final change standardizes on `$HOME/.cache/bazel-repo-cache` and
makes cache restore non-fatal.
## What Changed
- Expose one repository-cache path from
`.github/actions/setup-bazel-ci/action.yml` and export that path as
`BAZEL_REPOSITORY_CACHE` so `run-bazel-ci.sh` passes it to Bazel after
`--config=ci-*`.
- Move `actions/cache/restore` out of the composite action into
`.github/workflows/bazel.yml`, and make restore failures non-fatal
there.
- Save exactly the exported cache path in `.github/workflows/bazel.yml`.
- Remove `common:ci-windows
--repository_cache=D:/a/.cache/bazel-repo-cache` from `.bazelrc` so the
Windows CI config no longer disagrees with the workflow cache path.
- Pass `--skip_incompatible_explicit_targets` in the Windows `Bazel
clippy` job so incompatible explicit targets do not fail analysis while
the lint aspect still traverses compatible Rust dependencies.
## Verification
- Parsed `.github/actions/setup-bazel-ci/action.yml` and
`.github/workflows/bazel.yml` with Ruby's YAML loader.
- Resubmitted PR `#16740`; CI is rerunning on the amended commit.
## Why
`provider_auth_command_supplies_bearer_token` and
`provider_auth_command_refreshes_after_401` were still flaky under
Windows Bazel because the generated fixture used `powershell.exe`, whose
startup can be slow enough to trip the provider-auth timeout in CI.
## What
Replace the generated Windows auth fixture script in
`codex-rs/core/tests/suite/client.rs` with a small `.cmd` script
executed by `cmd.exe /D /Q /C`, and advance `tokens.txt` one line at a
time so the refresh-after-401 test still gets the second token on the
second invocation.
Also align the fixture timeout with the provider-auth default (`5_000`
ms) to avoid introducing a test-only timing budget that is stricter than
production behavior.
## Testing
Left to CI, specifically the Windows Bazel
`//codex-rs/core:core-all-test` coverage for the two provider-auth
command tests.
This makes Responses API proxy request/response dumping first-class by
adding an optional `--dump-dir` flag that emits paired JSON files with
shared sequence/timestamp prefixes, captures full request and response
headers and records parsed JSON bodies.

This adds an `include_environment_context` config/profile flag that
defaults on, and guards both initial injection and later environment
updates to allow skipping injection of `<environment_context>`.
This PR adds root and profile config switches to omit the generated
`<permissions instructions>` and `<apps_instructions>` prompt blocks
while keeping both enabled by default, and it gates both the initial
developer-context injection and later permissions diff injection so
turning the permissions block off stays effective across turn-context
overrides.
Also added a prompt debug tool that can be used as `codex debug
prompt-input "hello"` and dumps the constructed items list.
