Sep 17 00:00:00 2001 From: gusthoff Date: Sat, 20 Jun 2026 00:32:02 +0200 Subject: [PATCH 019/198] Python: extend unit tests for extract_projects.py (Diag class, verbose/inactive paths, same-project branch) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add three groups of tests to test_extract_projects.py: Diag class (lines 28-40): new TestDiag class with three tests verifying that __init__ stores all four fields and __repr__ produces "file:line:col: msg" format, including an edge case with zero/empty values. analyze_file() coverage-improvement tests (B2, B3) — added to TestAnalyzeFile: - test_code_block_at_sets_inactive: sets code_block_at=9999 so no block's line range matches; all blocks stay inactive and the inner loop hits the continue path (lines 188-191, 211). Asserts no project directory is created. - test_verbose_prints_headers: sets verbose=True; confirms project name appears in stdout (lines 246-248). - test_second_call_same_project_logs_exists: calls analyze_file() twice on the same RST; second call prints "already exists" (lines 234-237). - test_no_check_verbose_skip: verbose=True with a no-check block; confirms "Skipping" appears in stdout (line 344). Same-project second block (line 218 false branch): new class TestAnalyzeFileSameProjectTwoBlocks with an RST containing two no-check Ada blocks sharing project=SameProject; verifies both are processed without error and two block_info.json files are written.

check_block() with no_check=True (early return, no subprocess); cache hit with status_ok=True/False/None; force_checks=True bypassing cache; BUTTONS check failure for empty buttons list; real Ada syntax check (gcc -gnats) for valid and invalid Ada; real gprbuild compile for a valid Ada procedure and a procedure with a syntax error; real run check for a compilable Ada program; BUTTONS check for selected toolchain with non-"no" button; and check_code_block_json() with a missing file and with a valid no-check block. Key fix in _make_block(): changed `buttons = buttons or ["no"]` to `buttons = ["no"] if buttons is None else buttons` so that passing `buttons=[]` explicitly is preserved (an empty list is falsy, causing the `or` form to silently substitute `["no"]`). Added compile_it and run_it parameters to _make_block() to allow tests to reach the BUTTONS check without triggering the compile path that requires a project file.

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds test_chop.py in the package test directory covering manual_chop and cheapo_gnatchop edge cases not present in the existing frontend/sphinx/tests/test_chop.py. manual_chop additions: .ads and .adb Ada extensions, empty input, input with no !filename lines at all, garbage before the first valid file marker, single filename with no content, fake extensions not matched. cheapo_gnatchop additions: dotted package body names (Foo.Bar → foo-bar.adb), dotted procedure names, triple-dotted names, spec-only files (.ads), empty input, only-garbage input, garbage before the first declaration, body-before-spec ordering. Does not cover real_gnatchop (requires the Ada toolchain; already tested in sphinx/tests/test_chop.py).

The existing tests did not reset these globals, so any test that set verbose=True would have leaked state into subsequent tests. Add new TestCheckProjectsExtended class with four tests: - test_get_blocks_from_json_file_returns_none: monkeypatches CodeBlock.from_json_file to return None; verifies get_blocks() prints ERROR and returns an empty dict (lines 30-32). - test_get_blocks_duplicate_project: two block_info.json files with the same project name; verifies both are accumulated in the list under one key (false branch of "if not b.project in projects:" at lines 38-40). - test_get_projects_verbose: sets cp.verbose=True and calls check_projects(); verifies the project header appears in stdout (lines 87-88). - test_check_projects_skips_inactive_block: serialises a block with active=False; monkeypatches cp.check_block to track calls; verifies the inactive branch (line 93 continue) is taken and check_block is never called.

The existing tests always relied on the isolated_toolchain_path fixture, which pre-populated TOOLCHAIN_PATH before set_toolchain() was called, keeping the guard permanently false. The new test uses monkeypatch.delitem to remove "root" from TOOLCHAIN_PATH within the isolated fixture scope; set_toolchain() then triggers init_toolchain_info() at line 13, repopulating the dict from the real .ini file. The assertion checks that "root" is present again after the call.

real_gnatchop is called, the project file is written, and block_info.json is created. Returns False (no error), covering the compile_it path in analyze_file() including prepare_project_block_dir() and to_json_file(). - test_analyze_file_run_button: same setup with a run_button attribute; covers the run_it branch (compile_it=True, run_it=True). - test_analyze_file_prove_button: SPARK Ada body with a prove_button attribute; write_project_file() uses spark_mode=True, covering the prove_it branch including the SPARK project-file path. All three tests require the Ada toolchain (gnatchop must be in PATH) and use the work_dir fixture so each test starts in a fresh temporary directory. Also removes line-number annotations from pre-existing section-header comments (line numbers are fragile and describe location rather than behaviour).

Renamed both to match. More importantly, nothing in CI ever ran the package's pytest suite -- only pyright type-checked it. Add a second job that installs the Ada toolchain (reusing the same install script and the same versions the package's own toolchain.ini already specifies, so there's no separate version list to keep in sync) and runs the existing test_rst_pipeline Makefile target. Verified locally: 377/377 tests pass at 99.61% coverage, matching the epub VM's results.

Each affected case is now two tests: a normal one asserting the diagnostic (and that the run carries on), and an `xfail` one asserting only the return value. This covers the prove button on a non-Ada block, the block with no button indicator, the block whose source text chops to nothing, and the `BlockCheck` JSON round-trip, where what `to_json_file()` writes is now asserted separately from what `from_json_file()` gives back. The shared RST fixtures move to class constants so both halves of a split use the same input. Verified on a host with the Ada toolchain: 377 collected, 373 passed, 4 xfailed, no XPASS, coverage 99.61%, `pyright .` clean. Deleting the `print_error()` calls now makes the new tests fail.

That is the right outcome, but it used to end the run with a traceback, and the reader's ERROR line alone does not say which of the two happened. A warning now names the file as rebuilt. It matters because the build directory is kept between runs, so a record damaged by an interrupted run survives until someone notices it. Adds `fmt_utils.warning()`, the counterpart of `error()`.

It claimed the example is "still extracted and checked", which is false for a block carrying a no-check class — extracted, then deliberately skipped. It now claims only that the example is extracted and the run was not cut short, which is what the warning is actually for. It could also fire for something the reader never tried to read: the caller guarded with `os.path.exists` while the reader guards with `os.path.isfile`, so a directory of that name announced a rebuild that then did not happen. The two guards now agree.

Do not treat every -`ERROR` line as a failure, though. `extract-code` prints one for each of the -two damaged per-block records it repairs and carries on from: a directory left -over from an earlier run with no info JSON file in it, which it removes and -rebuilds, and an info JSON file that is present but cannot be read, which it -rewrites. The second is followed by a `WARNING` line naming the file as -rebuilt and saying that the example is still extracted and the run was not cut -short. That is as far as it goes: it does not promise the example is checked, -which would be wrong for a code block carrying a no-check class — that one is -extracted and then deliberately skipped. Look into it even so: a build -directory is reused between runs, so a record damaged by an interrupted run -survives there until something reports it. -`check-code` and `check-block` print an `ERROR` line of their own (`Failed to -clean-up example`) when they cannot remove an example's build artifacts -afterwards, which leaves the outcome of the check unchanged. Match on the -message text of the errors listed above rather than on the `ERROR` prefix -alone. +Some malformed code blocks are reported only through an `ERROR` line in the +output, while `extract-code` itself still exits `0`. Check the output, not +only the exit code, to catch these. ## Verbose mode From 30f993cf1d1528f7867db77582f205a498cf1e7f Mon Sep 17 00:00:00 2001 From: gusthoff Date: Sat, 19 Sep 2026 05:49:32 +0200 Subject: [PATCH 198/198] Docs: drop the fix-plan paragraph from analyze_file()'s docstring The docstring described the unreachable error flag correctly, then went on to prescribe the fix (declare nonlocal, set the flag at the remaining error sites) and its consequences. A docstring documents the current contract for a caller; it is not the place to plan a repair.
