Inline comments:
In `@dfetch/commands/review_patch.py`:
- Around line 113-200: The `_review_project` method has too many branches and
conditional paths, exceeding the cyclomatic complexity limit of 8. Extract the
guard validations (checking for patch existence, on_disk_version, and local
changes) into a separate helper method that returns early if validation fails,
move the interactive review logic and non-interactive logic into their own
helper methods, and simplify the main method to orchestrate validation,
application, and restoration in a clearer sequence. This will distribute the
branching logic across focused helper methods while keeping the main method as a
clear orchestrator.
- Around line 70-78: The --count argument lacks validation, allowing negative
integers that produce unexpected Python slice behavior rather than a meaningful
CLI contract. Add a custom type validator to the add_argument call for --count
to ensure only positive integers are accepted. Additionally, update the logic
around line 173 where the raw count is forwarded to patch_count to validate
against negative values and clamp to valid ranges. Finally, modify the reporting
logic around line 181 to track and report the actual number of patches that were
successfully applied, not the requested count, since the effective count may
differ from what was requested.
- Around line 183-187: The logger.print_info_line call in the review_patch
function currently hardcodes the instruction to use git diff, but this is
inconsistent with non-Git superprojects like SVN that should use their own diff
commands. Make the diff command suggestion in the message VCS-aware by checking
the project's VCS type and conditionally including the appropriate diff command
(git diff for Git projects, svn diff for SVN projects, etc.) in the status
message printed to the user.
In `@dfetch/vcs/git.py`:
- Around line 785-793: Add the `--` separator before the path argument in both
the add_path and restore_staged methods to prevent Git from interpreting
option-style paths as flags. In add_path, insert `"--"` between `"add"` and
`path` in the command list passed to run_on_cmdline. In restore_staged, insert
`"--"` between `"--staged"` and `path` in the command list passed to
run_on_cmdline. This ensures Git treats the path as a positional argument rather
than a potential option flag.
In `@tests/test_review_patch.py`:
- Around line 79-97: Add a new test function to validate that negative count
values are rejected by the ReviewPatch command. Create a test that instantiates
ReviewPatch, mocks the required dependencies (create_super_project,
create_sub_project, in_directory, is_tty) similar to
test_review_count_1_uses_patch_count_1, and then calls cmd(_make_args(count=-1))
while asserting that this raises an appropriate validation error or exception.
This ensures the CLI contract maintains count-based validation and prevents
regression to slice-driven behavior for negative values.

In `@dfetch/commands/review_patch.py`:
- Line 260: The Ctrl-C handler is currently catching KeyboardInterrupt, clearing
the screen, and returning normally, but the UI message advertises "Ctrl-C abort"
which implies the command should abort. Locate the exception handlers that catch
KeyboardInterrupt (near lines 260 and 319-321 in the review_patch.py file) and
modify them to re-raise the KeyboardInterrupt exception after clearing the
screen, rather than returning normally. This will allow the outer finally block
to restore state before the command properly aborts.
- Line 47: The import statement in review_patch.py violates the command-layer
dependency boundary by directly importing from dfetch.terminal, which is not an
allowed dependency. The imports of Screen, is_tty, read_key, BOLD, DIM, and
RESET must be sourced from one of the allowed layers (dfetch.reporting,
dfetch.project, dfetch.manifest, dfetch.vcs, dfetch.util, or dfetch.log). Either
move these terminal primitives to one of the allowed modules or create a
wrapper/facade in an allowed module that exposes these utilities, then update
the import in review_patch.py to import from the allowed layer instead of
directly from dfetch.terminal.
- Around line 137-147: The mutations to the subproject via subproject.update()
and to git_super via git_super.add_path() are occurring before the try/finally
restore guard begins, which means if either call fails, the restore mechanism in
the finally block will not execute and the worktree/index could be left in an
inconsistent state. Move the subproject.update() call (with patch_count=0) and
the conditional git_super.add_path() call to occur after the try block starts,
so they are protected by the restore guard in the finally block. The same issue
also applies to the code in the range around lines 159-174, so ensure all
mutations that need protection occur within the try block.
- Around line 183-202: The ReviewPatch functionality needs to validate patch
files exist and are accessible before treating them as applicable or performing
worktree operations. Add comprehensive patch file validation in the ReviewPatch
method that performs checks similar to those shown in the diff (verifying patch
existence via subproject.patch, confirming the subproject version exists via
on_disk_version(), and checking for local changes via
has_local_changes_in_dir()) to ensure that chosen_count == -1 or any decision to
apply patches is only made when the patch file is actually valid and accessible.
Ensure this validation logic is applied consistently across all locations where
patches are processed (including the locations at lines 217-221, 233-246, and
290-297) before any worktree replacement operations occur, and validate the
actual patch file object when calling Patch.from_file to catch missing or
out-of-root patch files early.
In `@dfetch/project/subproject.py`:
- Around line 90-97: The apply_patches method accepts a count parameter but does
not validate the input, allowing invalid values like -2 to be passed and cause
unexpected behavior in the slicing logic. Add a validation guard at the
beginning of the apply_patches method that raises a ValueError if count is less
than -1, ensuring only -1 (meaning all patches) or positive values are accepted
as documented in the docstring.
In `@features/steps/git_steps.py`:
- Around line 264-266: In the subprocess.check_output call for the git status
command, add the `--` separator argument between the `--porcelain` option and
the path argument to prevent paths starting with a hyphen from being interpreted
as git options. Modify the command list from `["git", "status", "--porcelain",
path]` to `["git", "status", "--porcelain", "--", path]`.
- Line 10: Move the no-name-in-module pylint suppression from the inline comment
on the import statement (from behave import given, then, when) to the
module-level header. Locate the existing pylint disable comment on line 3 in the
module header and add no-name-in-module to that existing disable list, then
remove the inline # pylint: disable=no-name-in-module comment from the import
statement on line 10.

If subproject.update() succeeds but the subsequent git_super.add_path() raises, the except block only restored the saved metadata bytes, leaving the on-disk files at clean upstream while metadata claimed the original fully-patched state. Route the failure through _restore_project first, as _review_project already does, and add a regression test.

- Add missing docstrings to _validate_superproject, _check_count_conflicts, and GitLocalRepo._git_restore (pydocstyle consistency) - Drop unused `call` import from test_replay_patches.py - Clarify that the git-index staging behaviour in the replay-patches how-to only applies to Git superprojects; SVN has no staging step - Assert the SVN working copy is clean after replay-patches restores, mirroring the existing git "reports no changes" step Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01A7miizBGMoLEXXZxuq6XUJ
The checked-in recording predated the demo script's "cat patches/cpputest.patch" step and was hand-edited (mismatched terminal size, a stale 0.14.0 version string, and a "Press Enter to restore..." prompt that the piped invocation never actually produces). Regenerated it with asciinema + strip-setup-from-cast.sh against the current script, matching the terminal size/env of the other checked-in casts.

… pipe trick The demo script piped empty stdin into dfetch replay-patches to stop the recording from blocking on "Press Enter to restore...", but that made the checked-in cast/GIF display `echo '' | dfetch replay-patches cpputest` as if that's what a user should type. Use demo-magic's `p` to display the plain command while still feeding it empty stdin behind the scenes, and regenerate the cast and GIF to match.

This sandbox generated the recording at /home/user/dfetch instead of the /workspaces/dfetch path every other checked-in cast was recorded under. Every sibling cast keeps the trailing popd path (it's not stripped), so normalize the one line to match rather than removing it.

Drives dfetch replay-patches --interactive across two projects (cpputest, jsmn) through the newly-generalized interactive_helper.py, showing the tree TUI step through each project's patch and switch focus between them with the arrow keys. Extends the helper's key aliases with UP/LEFT/RIGHT (previously only ENTER/DOWN/SPACE, added for add -i's needs) since the replay-patches TUI uses all four arrows. Wired into generate-casts.sh and embedded in the patching how-to alongside the existing single-project cast.

ruff's TRY004 (enabled by the ruff 0.16.4 bump already on main) flagged _validate_superproject's RuntimeError for an isinstance check. diff.py and update_patch.py already use TypeError for the identical NoVcsSuperProject check (near word-for-word same message) -- replay_patches.py was the odd one out. Match the existing convention; both are handled identically by __main__.py's top-level except (RuntimeError, TypeError). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01A7miizBGMoLEXXZxuq6XUJ
- _stage_one: KeyboardInterrupt derives from BaseException, so the prior `except Exception` skipped restoration on Ctrl-C during staging. Switch to try/finally with a staged_ok flag so restoration always runs on any failure, including Ctrl-C. - Fix a misplaced quote in the "no patch file" warning so the project name lands inside the quoted `dfetch diff` command, matching update_patch.py. - Catch OSError alongside RuntimeError when stepping the interactive TUI (single- and multi-project) so a patch file that goes missing mid-review doesn't leave the terminal stuck in raw mode. - interactive_helper.py: reject trailing tokens after REPEAT instead of silently ignoring them; terminate the driven dfetch process if _drive raises instead of leaking it. - Demo scripts: resolve demo-magic.sh and workspace paths from the script's own directory (BASH_SOURCE) instead of the caller's cwd; use a unique mktemp workspace instead of a fixed directory name so a pre-existing directory of that name can't collide with the cleanup trap's rm -rf; preserve the replay command's exit status through cleanup. - Remove an unnecessary inline pylint suppression in svn_steps.py (other step files import `then` from behave without it). - Clarify that replay-patches stages "eligible selected projects" (skips ones with no patches or local changes), not unconditionally all of them. Verified: all 724 unit tests, the git and SVN replay-patches BDD scenarios, and both demo scripts end-to-end (exit 0, no leftover directories) still pass; ruff/pylint/mypy/pydocstyle/bandit clean.

…ee check - Validate each patch path in the interactive TUI stepper before handing it to Patch.from_file, mirroring SubProject._apply_patches' own skip checks (missing file, or outside the current directory). A rejected patch logs a warning and the step still advances, rather than crashing or silently applying an unvalidated path. Filtering the patch list up front was tried first but rejected: it shrinks the reported total, which threw off the fully-patched restore-path decision in combined mode. - CI: verify dfetch replay-patches actually leaves the working tree unchanged (snapshot git status before/after) instead of just checking it exits 0, in both the cygwin and the OS/Python matrix jobs. Runs under shell: bash explicitly so the check is identical on Windows (Git Bash) and Linux/macOS; verified against a real replay-patches run. Left unfixed with reasoning: - security/tm_usage.py's "preserve pre-existing staged changes" comment: verified against current code -- _can_review_project already calls has_local_changes_in_dir before staging, which skips any project with staged OR unstaged changes, so there's never a pre-existing staged state to lose. False positive; the reviewer's own analysis was scoped to replay_patches.py and git.py only, missing this upstream guard. - The dfetch.terminal import "layer violation": already verified in an earlier round -- pyproject.toml's actual enforced import-linter contract places dfetch.terminal in the same bottom layer as util/log, and lint-imports passes. The reviewer's guideline source (AGENTS.md's prose diagram) just omits it from the list. - Generalizing asciinema's exit-status propagation across all ~19 generate-casts.sh demo scripts: out of scope for this PR, which only fixed it for the two replay-patches demos it adds. Verified: 734 unit tests, ruff/pylint/mypy/pydocstyle/bandit/lint-imports, git+SVN replay-patches BDD scenarios, and the new CI check against a real replay-patches run all pass.

apply_patches() silently skips such a patch, so a non-interactive replay that hit one would still be treated as fully patched and take the unstage-only restore path, leaving the worktree out of sync with HEAD. Gate eligibility on all patch paths being safe instead, using the same check already added for the interactive stepper.
… worktree The CI clean-tree check (added in the previous commit) failed on the cygwin job: after a non-interactive replay applied all of a project's patches, restore assumed the reapplied worktree was already byte-identical to HEAD and only unstaged the git index, leaving the working tree dirty whenever re-fetch + patch application didn't reproduce HEAD exactly (e.g. environment-dependent line-ending normalization). Drop that "fully patched, so just unstage" fast path for git projects and always restore both index and worktree from HEAD instead. Do the same for SVN (always re-fetch and reapply on restore, rather than only when the worktree was left partially patched) so the same class of drift can't leave an SVN project's working copy uninspected either.
… dirty The clean-tree check's own workflow logs are unreadable when it fails -- step-security/harden-runner's process-monitoring output on Windows/cygwin runs to tens of thousands of lines, drowning the few lines the check itself prints. Upload the actual `git status`/`git diff` output as a build artifact on failure so it's inspectable directly instead of hunting through logs.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
_apply_review and _run_combined_review only forward a project's chosen patch count to the non-interactive apply_patches() call; the interactive TUI paths always hand the stepper the project's full patch list, so a project:N suffix was silently ignored once --interactive was set. Reject the combination up front instead, matching the existing --count/project:N conflict check.
…ostic The previous diagnostic step only wrote its diff artifact inside the "tree changed" branch, so if `dfetch replay-patches` itself exited non-zero (a crash, not just a dirty restore), bash's errexit aborted the script before that branch -- and before the artifact upload step ever had a file to upload. The last run's "replay-patches-diff-cygwin" artifact confirmed this: the check failed but zero artifacts were produced. Capture the command's own stdout/stderr and exit status unconditionally, and treat a non-zero exit the same as a dirty tree, so the artifact is always written before the step decides whether to fail.

dfetch replay-patchwhich stages the clean upstream source inthe git index and applies the selected patches to the working tree, so any
diff-aware editor sees
git diff(working tree vs index) showing exactlywhat the patches contribute. The command always restores original state on
exit — no permanent changes to working tree or index.
