This is a quality check. It should fail when someone submits broken files.
Yes XCSoar may be tolerant in some cases (and it shouldn't be.) But it also may do things with this data that isn't intended. Clean files are the happy path and the best tested path, therefore this should bark at anything that isn't properly done.
The point is to get people to fix their data.

Review on XCSoar#561: the point of a quality check is to get people to fix their data, and XCSoar being tolerant is not a reason to be. That holds without reservation for the files in data/content, which are ours to repair. A single damaged record costs the airspace it belongs to and costs the whole file its bbox, since repository.py derives that from the same parser, so tolerating one buys nothing. check_airspaces.py now requires a clean parse. It does not hold for files reached over a URI. A third-party source with a damaged record cannot be fixed here, and failing the run over it would leave the check permanently red on somebody else's file; BR, CA and JP each carry such records today. check_urls.py therefore keeps the lenient test, which still catches the case that matters there -- a URI that has started serving an error page instead of airspace. The two policies are named rather than implied: is_clean_openair() for what we ship, looks_like_openair() for what we link to. Every file in data/content passes the strict test once XCSoar#567 lands; before it, CA-ASP-National, MW-ASP-National and DE-ASP-HahnweideComp2017 fail it, which is the point.

You're right, and the specification backs you up — I checked instead of arguing from XCSoar's behaviour.
So I have done it your way throughout, and fixed the data rather than the check. The check. aerofiles decides again, and for files we ship it now fails on any parse error, not merely on a file that yields no airspace. The two policies are named rather than implied: What survives from the detour is reporting, never a verdict: That names the file, the scale and the consequence. The commit and its reversal are squashed out of the history. The data. Every airspace file in the repository now parses without a single error.
1481 → 1500, 16 → 17, 477 → 478 airspaces. No coordinate moves: every repaired line was compared against its original and the worst difference across all 21 is zero. The The waypoints, where I had made the same mistake. #566 fixes 23 field defects across three files: 17 rows in Two of the three are still rejected, and this time it is the reader rather than the data: aerofiles raises on the observation zone keys Merge order. #567 before #564, or the CI wiring turns |

1.5.6 carries two fixes this repository needs. Its CUP reader no longer discards a whole file over an observation zone key it does not model, which is what rejected CZ-WPT-WaveCamp-2022-OBv1.cup and GLB-WPT-ProvingGrounds-XCSoar.cup: both are written by SeeYou and carry SpeedStyle and MaxAlt in their task sections. Both parse under 1.5.6. It also rejects a runway direction outside 0 to 360 degrees, the field being a heading rather than a runway designator. That catches the two impossible values in FR-WPT-National-XCSoar.cup, 3000 and 2200, repaired separately. Note that aerofiles still imports dateutil without declaring it as a dependency, so it remains an undeclared requirement here; XCSoar#561 adds the pin.

aerofiles 1.5.5 imports dateutil but declares no dependencies of its own, so pip install -r requirements.txt does not bring it in. Every script that parses OpenAir has been working only because the GitHub runner image happens to ship python-dateutil; the same commands fail on a clean checkout.
check_airspaces.py could never have run: aerofiles' Reader takes the file as a required constructor argument, so the script raised TypeError before opening anything, whatever it was passed. check.sh also hands it a directory rather than a file, and check.sh itself is wired into no workflow, so nothing has been checking airspace content. Take files or directories, and report per file instead of throwing on the first problem. Read bytes and fall back to latin-1, because the published set is not all UTF-8: NL-ASP-National-XCSoar.txt is ISO-8859-1 and cannot be decoded as UTF-8 at all. The decision of what counts as airspace moves to script/lib so that the URI check can reach the same verdict. One parsed airspace is the minimum, because a single-area file is legitimate -- DE-ASP-Military-Low-Flying.txt holds exactly one -- while anything serving an error page parses as none.
A HEAD request only proves that something answered. An airspace URI that starts serving an error page still passes it, and the file reaches the pilot describing nothing: daec.de answers a missing file with HTTP 200 and a 54 byte error body rather than a 404, and aip.net.nz answers 200 with an Incapsula block page. Entries of type airspace pointing at a .txt are now downloaded and parsed; everything else keeps the cheap HEAD. Knowing an entry's type means reading whole manifest records rather than bare uri= lines, so the manifest is parsed into records. Hosts that refuse the client are reported apart from failures. gliding.co.nz answers 403 to every path including / and /robots.txt from a data centre, and a Cloudflare challenge to anything without a browser, so a runner cannot tell a blocked file from a removed one. Failing on that would leave the check permanently red over a file pilots download without trouble, so 403, 429 and 451 are listed separately and 404 and 500 still fail. Also accept a local path, which is how check.sh has always invoked this and which raised MissingSchema every time: get_urls_from_file() existed but was never called.
A bare pass or fail does not say what to look at. Counting "AC" lines
without parsing gives the size of the file, so the log can contrast it with
what aerofiles actually reached: "4 airspace blocks, aerofiles read 0
(10 parse errors, no bbox)" names the file, the scale of the problem, and
the consequence. Clean files stay on the short form, "288 airspaces".
The verdict itself stays with aerofiles. XCSoar accepts more than the format
allows -- a lowercase hemisphere, and degrees/minutes/seconds beside decimal
minutes, which the specification forbids outright ("Do not mix DMS and DDM
notations. Stick to one definition throughout the file.") -- and passing a
file because XCSoar copes would hide the defect rather than get it fixed.
Review on XCSoar#561: the point of a quality check is to get people to fix their data, and XCSoar being tolerant is not a reason to be. That holds without reservation for the files in data/content, which are ours to repair. A single damaged record costs the airspace it belongs to and costs the whole file its bbox, since repository.py derives that from the same parser, so tolerating one buys nothing. check_airspaces.py now requires a clean parse. It does not hold for files reached over a URI. A third-party source with a damaged record cannot be fixed here, and failing the run over it would leave the check permanently red on somebody else's file; BR, CA and JP each carry such records today. check_urls.py therefore keeps the lenient test, which still catches the case that matters there -- a URI that has started serving an error page instead of airspace. The two policies are named rather than implied: is_clean_openair() for what we ship, looks_like_openair() for what we link to. Every file in data/content passes the strict test once XCSoar#567 lands; before it, CA-ASP-National, MW-ASP-National and DE-ASP-HahnweideComp2017 fail it, which is the point.
iter_airspace_files() passed over a directory with no *.txt, so a run that was given a readable file alongside such a directory reported success without ever saying it had checked nothing from it. That matters because check.sh hands this the whole airspace tree. A build that stopped producing airspace, or an output layout that moved, would look exactly like a clean run. Only the case of no arguments producing nothing at all was caught, and that is not the case that will happen. Empty directories are now reported per argument and fail the run: FAIL no *.txt in directory output/content/airspace Reported by CodeRabbit on XCSoar#561. The function had no tests; it has six now, covering nested expansion, an empty directory beside a good file, a bare file argument, and no arguments at all.
Both checks had tests for how they read their input and none for what they do with a verdict once they have one. check_airspaces.py: every MainTest case exercised the argument expansion, so main() could have collected check_file() failures and then dropped them while the file stayed green. One malformed file now goes through main() and its exit status is asserted -- the body is the TYPO3 error text the DAeC server really served in place of airspace. check_urls.py: nothing called check_urls() at all. looks_like_openair() was tested directly in test_openair_content.py, but not the path that reaches it, so a regression that skipped the content check, or ran it and disregarded the answer, would have reported an HTML error page as PASS with every test passing. The new case answers 200 with a 404 page and asserts the URL is reported failed and not merely blocked; its counterpart answers 200 with real airspace, without which a check that failed everything would satisfy the first. Verified by breaking each path on purpose: dropping the failure from main() fails only the first new test, and skipping looks_like_openair() in check_record() fails only the second. 36 tests pass.
The file this repository ships has to parse without a single error, which is a stricter promise than "holds some airspace", and it is the reason check_airspaces.py calls is_clean_openair() where check_urls.py calls looks_like_openair(). Nothing held it to that: the failure cases went through main() with bodies carrying no airspace at all, which the lenient test rejects just as readily. Swapping check_file() to looks_like_openair() therefore left all 36 tests passing. A file that satisfies the lenient test and fails the strict one closes that: real airspace followed by a record mixing coordinate notations, the defect this check was written to catch. With it, that swap fails exactly one test.
