It is ordered by how much each class of defect has +actually cost on this project. + +1. **A silent deviation.** The port does something other than the reference and + nothing says so. This is the expensive one, because it reads as correct. + Every difference should carry a comment giving the reference's behaviour + and the reason, *and* an entry in `$1`'s traps file in the same change. A + difference recorded only in the comment is half-silent: the next + translation into `$1` meets the same fork and will not be reading this + file. Note that "the reference could not be done here" is not the + threshold --- a different construct reaching the same behaviour is a + deviation too, and is the kind that goes unrecorded. +2. **A trap from the list, taken.** Go through the categories in `$1`'s traps + file that the diff touches and check each one. Grep the diff for the + constructs those entries name in bold. These are, by construction, things + that compile and pass a casual test. +3. **A reference semantic reproduced by idiom rather than by meaning.** Check + `traps-csharp.md` for anything the diff touches: case folding, trimming, + number parsing, regex anchoring, exception filters, newline handling, + stream encoding, path manipulation. The local one-liner is usually close + and occasionally wrong. +4. **A dropped test.** Every reference case needs a counterpart here. Run + `compare_inventory.py` rather than eyeballing it, but also look at whether a + *translated* case still asserts the same thing --- the inventory check + compares names, not bodies. +5. **A test that asserts the port's behaviour instead of the reference's.** + The worst failure mode available, because it makes the gap permanent and + invisible. A test named for what the code does rather than for what the + contract requires is the signature. +6. **Structure drift in the source.** A file in the wrong folder, a renamed + member, a reordered file --- each one costs the side-by-side diff for the + life of the file. This applies to the source only: the four test suites are + laid out differently on purpose, and only the test *names* are held in + step. +7. **A new dependency**, including a transitive one and including test-only. +8. **The pure stages reaching for something real.** Anything up to `Engine/` + that touches the engine, the filesystem or the console. In Python, + a binding import at module scope. +9. **House conventions**: copyright header, tabs or spaces to match the + language, expected-first assertions, no literal non-ASCII in source, no em + dashes and 80-column wrapping in Markdown. + +## What not to raise + +- Style preferences the existing code does not already follow. +- "This could be simpler" where the reference is shaped the same way.

The four parsers +disagreed about which tokens are options, what a repeated option means and what +an unknown argument costs, so every one of those decisions had already moved +into shared code --- leaving each library holding only the match from a token to +a row of the table, which is twenty lines to write. So C# depends on Document +Filters alone, and C++17 on Document Filters alone. xUnit and Catch2 are +test-only and are never restored by anyone running the sample; the end-to-end +script needs nothing beyond Python itself. The same rule applied again in [`python/`](./python): the published binding, and -`argparse` and `unittest` from the standard library. Nothing from PyPI. +`unittest` from the standard library. Nothing from PyPI. + +And again in [`java/`](./java), which never had a parser to lose: the published +samples in `samples/java` bring in none, so this port was written against the +hand-written table from the start --- and it is the shape the other three +converged on. Its only dependency is the binding jar already vendored +at `bindings/java/lib`, and its suite is a ~200-line runner on the JDK alone +rather than JUnit. The build is Gradle through the wrapper, at the same +version `samples/java` already pins. + +## What CI checks + +Two status checks are meant to be required on `master`. They ask different +questions and neither substitutes for the other: + +| Check | Workflow | Asks | +| --- | --- | --- | +| `CI gate` | [`cli.yml`](../.github/workflows/cli.yml) | did every affected suite pass? | +| `Ports landed` | [`ports-landed.yml`](../.github/workflows/ports-landed.yml) | did the three translations move with the reference? | + +**Why one gate and not one check per language.** A workflow skipped by a +`paths:` filter reports no status at all, so a required check that gets +filtered out leaves the pull request waiting forever for something that will +never arrive. `cli.yml` therefore always runs, filters *inside* itself, and +ends in a `ci-gate` job that reads every other job's result. A job skipped +because nothing it covers changed counts as a pass; a failure or a +cancellation anywhere fails the gate. `ci-gate` is the only context from that +workflow branch protection should name. + +What runs inside it: + +| Job | What it proves | +| --- | --- | +| Detect affected suites | which languages this change touches; everything below is filtered on it | +| C# / C++17 / Python / Java | each implementation builds and its own suite passes, on each OS in its matrix | +| Contract moves first | a behaviour change carries something the ports can be moved by: a shared fixture, or a test in that language's own suite | +| Cross-implementation parity | all four binaries run the same command lines and are compared byte for byte. The only job that compares the implementations to *each other* | +| Validate release version, Package, Publish | the release path, which runs only on a manual dispatch with `release` ticked | +| CI gate | the aggregate of all of the above, and the required check | + +### The two labels + +Both checks have an escape hatch, and they are easy to confuse: + +| Label | Says | Stands down | +| --- | --- | --- | +| `contract-unchanged` | this change needs no shared fixture and no new test | Contract moves first | +| `ports-unaffected` | this reference change has no counterpart in the ports | `Ports landed` | + +A refactor needs both halves understood. It pins nothing new, so +`contract-unchanged` is right --- and it still has to be mirrored in the three +ports, because the whole value of the mirror is that two implementations can +be diffed by eye, and a rename landing only in `csharp/` destroys that. So +`contract-unchanged` deliberately does **not** stand down `Ports landed`. +`ports-unaffected` is the narrow case: a C#-only build detail, or a `csharp/` +construct the other three already express correctly their own way. It is a +claim you sign for. + +### How `Ports landed` decides + +It looks at the commits on your branch, not at any agent's run history --- +porting by hand and committing it yourself satisfies it identically. A check +only a bot could turn green would make the bot mandatory, and it is not. + +It goes red while a port pull request is still open against your branch, and +while any port's newest commit is not a descendant of the reference's newest +commit. "After" is ancestry rather than timestamps, which a rebase rewrites. +Push a further change to `csharp/` and the ports are stale again, so the +check reopens until they catch up. + +### Running the same checks locally + +The five verification rings, run outward --- each port's own suite, the shared +fixtures inside it, `compare_inventory.py`, `end2end.py`, then `compare.py` +--- are what CI runs and are all runnable here. Stop at the first failure and +fix it there: an inner ring's failure explains itself, an outer one does not. +The commands, and the table of what each ring is blind to, are in +[`design/porting/workflow.md`](./design/porting/workflow.md). ## Exit codes diff --git a/DocFiltersCli/cpp17/CMakeLists.txt b/DocFiltersCli/cpp17/CMakeLists.txt new file mode 100644 index 0000000..48b7c49 --- /dev/null +++ b/DocFiltersCli/cpp17/CMakeLists.txt @@ -0,0 +1,121 @@ +cmake_minimum_required(VERSION 3.16) + +# --------------------------------------------------------------------------- +# docfilters (C++17) --- the C++ port of DocFiltersCli/csharp/. +# +# Builds standalone, the same way csharp/DocFiltersCli.csproj does: this +# file never fetches a test framework, so `cmake --build` here never touches +# the network for anything the shipped tool needs.

The same reasoning applies to `CaseProbe` and to +`OutputPlanner`'s collision key. + +### `string.Trim()` is Unicode whitespace, and a `std::string` has no idea + +**C#** `Trim()` with no argument removes `char.IsWhiteSpace`: U+0009 to U+000D, +U+0085, and the space, line and paragraph separator categories --- so the +no-break spaces U+00A0, U+2007 and U+202F are included, and the information +separators U+001C to U+001F are not. **C++17** a `std::string` is bytes, and +the obvious loop over `isspace` sees only the six ASCII ones. + +**Rule** Decode before trimming, and carry the table: the set is enumerable and +about twenty-five characters long. Do not reach for `isspace` on a byte. +`Strings::trim` and `Strings::isAllWhiteSpace` are the whole of it, and nothing +else in the port asks the question. + +It was wrong here until it was not. `Strings::trim` folded the ASCII six, and +`InputEnumerator`'s `isBlank` looped `std::isspace` over bytes where the +reference calls `string.IsNullOrWhiteSpace`.

A metadata value padded with U+00A0, or + with the U+3000 ideographic space that is ordinary in CJK documents, printed + with the padding here and without it in the other three ports. +- A `--list` file line holding nothing but a no-break space is a blank line to + the other three ports and was a path to open to this one --- a different exit + code, not only different bytes. +- `ParseIdList` (`--include-types "PDF;DOCX"`) and `EngineLog`'s module + list, both of which need the user to type one. + +**No suite saw it**, which is the part worth remembering. The unit test +asserted the divergent behaviour and was named for it; the conformance fixtures +stop at the plan; the end-to-end checks assert properties; and the parity +comparison would have caught it only against a document whose metadata carries +such a character, which `tests/e2e/test.pdf` does not.

A lone surrogate can only +be the three-byte form `0xED 0xA0..0xBF 0x80..0xBF`, which a lenient UTF-16 to +UTF-8 conversion of a Windows filename produces. + +**Rule** No `IsPaired`: `decodeSurrogate` recognises the three bytes and +`Escape` writes `\uXXXX`, lowercase hex, consuming all three. Test inputs are +those byte sequences, written as separate string literals so `\x` does not +swallow the next hex digit. A CESU-8 pair (two such sequences) is escaped as +two, where C# would write the character; nothing in this port produces one. + +### A narrow `main` on Windows has already lost the command line + +**C#** `string[] args` is UTF-16, and so is every path from there down. +**C++17** the CRT converts the UTF-16 command line through the active ANSI code +page before `main` sees it, so a filename the code page cannot spell arrives as +`?` characters. Measured: `docfilters identify .txt` reported +`E_NO_INPUTS: ...\???.txt` while the C# tool opened the same file. + +**Rule** `wmain` on Windows, convert each argument to UTF-8 once, and keep UTF-8 +everywhere after that --- which is also what the Document Filters C++ binding +expects (`DF::u8_to_w` is the first thing it does with a narrow filename). + +### `std::filesystem::path` converts narrow strings through the ANSI code page + +**C++17** `fs::path(utf8)` and `path.string()` are not round trips on Windows: +both go through the active code page. A name that survived `wmain` is destroyed +by the first `fs::path` that touches it. + +**Rule** One named seam, used at every crossing: `FilePath::of` / +`FilePath::toUtf8` in `Runtime/IFileSystem.h` wrap `u8path`/`u8string`, which +are the two calls that state an encoding. On POSIX both are the identity, which +is why this defect is invisible on Linux. + +### The `*A` Win32 family re-encodes silently + +`GetEnvironmentVariableA`, `GetModuleFileNameA`, `ShellExecuteA`, +`GetFileVersionInfoA` all take the active code page. The C# reference gives no +hint that this exists, because `Environment.GetEnvironmentVariable`, +`AppContext.BaseDirectory` and `Process.Start` are wide underneath. + +**Rule** `*W` plus the `FilePath` seam. While you are there: `MAX_PATH` is not a +limit on Windows, so `GetModuleFileNameW` needs a growable buffer --- it +truncates silently otherwise. + +### A non-ASCII character in a source file is a build-configuration bet + +MSVC reads a BOM-less source file in the active code page unless told otherwise, +so a literal `é` or `…` in a string or a comment is not portable. The contract +text is worse than source text: `--to`'s help string carried a U+2026 ellipsis, +which made `arguments.txt` --- compared byte for byte by four suites --- depend +on the encoding each one happened to read. + +**Rule** ASCII in sources, `\xNN`/`\uNNNN` escapes in tests that need a specific +byte, `...` in anything the contract compares. + +--- + +## Streams and the console + +### Text-mode stdout translates line breaks into binary output + +**C#** `Console.OpenStandardOutput()` is a byte stream. **C++17** on Windows +`std::cout` is in text mode, so every `0x0A` inside a PDF or a PNG written to +`--stdout` becomes `0x0D 0x0A`. + +**Rule** `_setmode(_fileno(stdout), _O_BINARY)` before writing document bytes; +`SystemConsole::openStandardOutput` is the one place that does it. + +### `std::getline` ends a line only on LF + +**C#** `StreamReader.ReadLine` and `File.ReadAllLines` end a line on CR, LF or +CRLF. **C++17** `getline` with the default delimiter leaves the CR on the end of +every line of a CRLF file, and reads a CR-only file as one line. + +**Rule** Split by the same rule as the reference: `Strings::splitLines` is the +one implementation, used by `--files-from -` and the fixture reader alike. + +### An imbued locale re-encodes what you write + +Giving an iostream a locale with a non-trivial `codecvt` changes the bytes that +reach the file, after the code that produced them has decided what they are. + +**Rule** The port never calls `imbue`, and should not start. Output encoding is +settled by the string, not by the stream. + +--- + +## Numbers and patterns + +### `std::stoi` throws where `int.TryParse` returns false + +**C#** `int.TryParse(text, NumberStyles.None, ...)` rejects a sign, surrounding +whitespace and trailing text, and returns `false`. **C++17** `std::stoi` skips +leading whitespace, accepts a sign, ignores trailing text, and throws on +failure --- three different behaviours, one of which terminates the process if +nothing catches it. + +**Rule** `std::from_chars` after a hand-written shape check, which is what +`ValueParsers::tryParseDigitsOnly`, `PageRange` and `OutputNameTemplate` each +do. `from_chars` also reports overflow as `std::errc::result_out_of_range` +rather than by exception. + +### `std::regex_match` is not `Regex.IsMatch`, and `$` is not `\z` + +**C#** `IsMatch` searches; the reference therefore anchors its patterns by hand +as `^(?:...)\z`. **C++17** `std::regex_match` requires the whole subject to +match, and the ECMAScript dialect has no `\z` at all --- it parses as an +identity escape for the letter `z`. `$` also differs: .NET's matches before a +trailing newline, ECMAScript's only at the end. + +**Rule** Anchor structurally, not textually: `NameMatcher` builds the bare body +and calls `std::regex_match`. Translating `^(?:...)\z` literally would silently +match a `z`. + +### A malformed pattern throws a different exception + +`std::regex_error` where .NET throws `ArgumentException`. Both must come out as +the same `E_BAD_VALUE`, or the two ports disagree on a corpus case. + +--- + +## Filesystem + +### `std::filesystem::path` knows only the host's separators, and normalises + +**C++17** a backslash is an ordinary character in a filename on Linux, so +`fs::path("..\\..\\windows\\system32\\config").stem()` returns the whole string +there. Output names are plain strings in this tool's contract --- the same +`--out-name` must render identically on both platforms. + +**Rule** Normalise separators yourself before any lexical operation +(`OutputNameTemplate::normalizeSeparators`), and treat path text as text. + +### The `error_code` overloads fail quietly + +**C++17** `fs::directory_iterator(path, ec)` that failed compares equal to +`end()`, so ignoring `ec` turns an unreadable directory into an empty one; a +subtree the walk cannot read is then skipped in silence, and a run given only +that directory reports `E_NO_INPUTS`. `fs::exists(p, ec)` returns `false` on +error, so "not there" and "could not tell" are the same value. + +**Rule** Check `ec` at every call, and decide explicitly which of the two +answers you mean. The reference throws in both cases, which is what callers are +written for. + +### The host is not the volume + +Case sensitivity belongs to the directory, not to the operating system: a +mounted NTFS volume under Linux folds case, and Windows can mark one directory +case-sensitive. `std::filesystem` will not tell you. + +**Rule** Ask the directory, read-only (`CaseProbe`), and fall back to the host +default only when it cannot answer. + +--- + +## Processes and signals + +### `std::system` runs a shell + +**C#** `Process.Start` with `ArgumentList` passes each argument through as one +argv slot. **C++17** `std::system("xdg-open " + path)` hands the whole string to +`/bin/sh`, so an output named `doc$(touch pwned).txt` executes. Measured: the +file was created. + +**Rule** `posix_spawnp` with an argv array (`Runtime::Viewer`), or +`ShellExecuteW` on Windows, which takes the path as a verb target rather than as +a command line. The C# analogue of the same mistake is building an argument +*string*, which splits on a quote in the filename. + +### A signal handler may do almost nothing + +Only `volatile std::sig_atomic_t` assignment and lock-free atomic operations are +permitted --- no allocation, no locks, no iostreams. + +**Rule** Record a flag and return; everything else happens on the polling side +(`Runtime::Interruption`). See the non-traps below for what *is* allowed. + +--- + +## Declaration order + +### A definition must precede its use; the reference's order does not + +**C#** members may appear in any order; the compiler reads the whole type +first. **C++17** a name must be declared before it is used, so a file written +in the reference's order will not compile: `bindVerb` is the fourth member and +calls `validateTokens`, which is the seventh. + +Written the obvious way, the file comes out callee-first --- `looksLikeOption` +at the top, `bindVerb` near the bottom, `CommandLineApp::run` last of all --- +which is close to the reverse of the reference. That is how every `.cpp` in +this port reads, `src/Cli/CommandLineApp.cpp` included. + +Forward-declaring the helpers at the top of the anonymous namespace, so that +the definitions can follow the reference's order with `run` and `bind` first, +was tried and reverted. Two reasons, and the second is the one that decided +it: + +- It duplicates nine signatures in the file that is diffed across languages + more than any other. They disagree loudly if they drift --- change one and + the other becomes a second overload, so the call fails to resolve or the + definition is reported unused --- but it is still a second place to edit. +- It fixes one file. `src/Configuration/OptionsValidator.cpp` has the same 25 + members as the reference and nothing like its order: the `check*` helpers + fill the anonymous namespace and the three `validate*` entry points sit + underneath them. Every other file with file-local helpers is the same. + Buying exact order in `Cli/` leaves the port with two conventions and no + way to tell which a given file follows. + +**Rule** Define file-local helpers callee-first and let the order differ from +the reference. Match the reference on *names* and on *which* members exist, +and look them up rather than reading top to bottom. Do not add a +forward-declaration block to restore the order; if a future change makes +exact order worth having, it has to be worth having in every file at once. + +Nothing checks any of this. `compare_inventory.py` compares *test* names +across the four suites; no ring looks at source member names at all, so a +helper quietly renamed or dropped in this port is invisible to the build. +That is the gap to close if source parity is ever worth enforcing --- and it +would be a names check, not an order one. + +## Toolchain + +### MSVC accepts what GCC rejects, and the reverse + +MSVC binds a temporary to a non-const lvalue reference without complaint; GCC +and Clang refuse. GCC's warnings catch truncation and format problems MSVC says +nothing about. Neither compiler alone tells you the port builds. + +**Rule** Build both before calling anything done. Several defects in this port +existed only on one platform, and the use-after-free above only *mattered* on +one. + +### `abort()` does not exit 134 everywhere + +Windows exits 3; POSIX reports SIGABRT as 134. Any end-to-end assertion on the +exit code of a crash has to say which. + +### `std::error_code::message()` is platform text + +The wording differs between the MSVC runtime and libstdc++, so it cannot appear +in anything the conformance fixtures compare. Put your own message in the error +and keep the system text out of the contract. + +### A test binary that links the engine needs the engine on its path + +`catch_discover_tests` runs each case in its own process at build time; without +`DL_PATHS "$"` every one of them fails to start, for +reasons that look nothing like a missing DLL. + +--- + +## Tests + +### A `[Theory]` is one `TEST_CASE` with a loop + +**C#** a `[Theory]` with `[InlineData]` rows is one named test that runs once +per row, and `compare_inventory.py` collapses the rows to that one name. +**C++17** the port writes one `TEST_CASE` under the same name and loops over the +rows inside it, rather than using `GENERATE`, so the loop and the C# row list read side by +side. A failing row is then reported by its `CHECK`, not by its own test run. + +**Rule** Same name as the `[Theory]` method, rows in a braced list. See +`a dash token that is not an option spelling is a path`. + +--- + +## Verified non-traps + +Things that look like the list above, were measured on both toolchains, and are +not defects. Recorded because each one has already been raised twice. + +- **`std::filesystem::rename` does replace an existing file on Windows.** The + MSVC standard library calls `MoveFileExW` with `MOVEFILE_REPLACE_EXISTING`; + measured, the rename succeeds with an empty `error_code` and the destination + holds the source bytes.

It goes through the +design and the shared fixtures first, not straight into `csharp/`. + +Nothing here is folklore: every entry names the reference call site it comes +from, and most name the port that paid for finding it. Where a claim was +measured, the trap list that measured it says so and is cited. + +--- + +## Text and culture + +### `FoldToken` is ASCII-only, and only some values go through it + +`Configuration/ValueParsers.cs`. Values drawn from a vocabulary *this tool +publishes* are folded A-Z to a-z and nothing else, so `PDF`, `Pdf` and `pdf` +are one token. A locale-aware fold maps `I` to the dotless `ı` under a Turkish +locale, and `--to TIFF` would stop resolving on a Turkish machine --- in C#, +Java and Python alike, and in C++17 where `std::tolower` is locale-sensitive +too. + +**Rule** Port the fold, not `toLowerCase()`. And port *where* it is applied: +the argument table calls it for `--to`, `--on-error`, `--applies-to` and the +two log levels, and for nothing else. Paths, globs, regular expressions, +`--out-name` templates, `--filter` text, passwords, `--codepage` and the +`--options` string are used exactly as typed. Widening that set is a contract +change, and so is narrowing it. + +### An enum's name, lowercased, is the wire format + +`Execution/StructureReport.cs`, `Planning/FormatSpec.cs`: +`value.ToString().ToLowerInvariant()`. .NET returns the identifier, never +anything localised, so `PageElementType.TextBox` prints as `textbox`. + +**Rule** The contract is the *C# identifier* lowercased, not your enum's name +lowercased. Java separates words with underscores where C# runs them together, +so `TEXT_BOX` cannot be the source of this string. See "Enum names are not the +reference's names" in `traps-java.md`. + +### `string.Trim()` and `char.IsWhiteSpace` are .NET's set + +`ValueParsers.cs` trims each part of a `;`-separated list with the no-argument +`Trim()`. That set is fixed and not culture-sensitive, but it is not the same +as anyone else's. The set is the Unicode one: U+0009 to U+000D, U+0085, and the +space, line and paragraph separator categories --- so the no-break spaces +U+00A0, U+2007 and U+202F are in it, and the four information separators +U+001C to U+001F are not. + +Both Python and Java had to build the predicate rather than call the local one, +and arrived at the same definition independently: `is_whitespace` in +`python/docfilters_cli/configuration/value_parsers.py` subtracts U+001C-U+001F +from `str.isspace()`, and `isWhiteSpace` in Java's `ValueParsers` names the +categories outright. `String.trim()` and `str.strip()` are both wrong, in +opposite directions. + +**Rule** Mirror the set, not the method name. Python and Java each pin it with +a test (`is_all_whitespace_matches_is_null_or_white_space`, +`isNullOrWhiteSpaceMatchesTheReference`). + +C++17 reaches it a third way, because a `std::string` is bytes and the standard +library has no Unicode tables: `Strings::trim` and `Strings::isAllWhiteSpace` +decode the UTF-8 and carry the set as a list. It folded the ASCII six until +writing this file turned the gap up; see `traps-cpp17.md` for what that cost +and why nothing caught it. + +### Tokens are compared with `StringComparison.Ordinal` + +`Cli/ArgumentDefinition.cs`, `Execution/CanvasConversion.cs`. Never the default +overload, never the current culture. + +**Rule** Ordinal, byte for byte. In a language whose default comparison is +already ordinal this costs nothing; in one where it is not, it is the +difference between `--to` resolving the same way everywhere and resolving the +same way on the machines anyone happened to test. + +### An unpaired surrogate is written as U+FFFD + +The console's UTF-8 encoder substitutes the replacement character. A +`PrintStream` writes `?` instead, which is why the Java port builds its own +encoder (`traps-java.md`). + +--- + +## Numbers and patterns + +### `int.TryParse(text, NumberStyles.None, InvariantCulture, out value)` + +`ValueParsers.cs`, five call sites, and this exact overload every time. It is +the numeric contract for `--pages`, page indices, counts, limits and `--form`. + +Measured in `traps-cpp17.md`: it rejects a sign, surrounding whitespace, group +separators and a decimal point. `std::stoi` accepts most of them and throws +rather than returning false; Python's `int()` accepts an underscore, a sign and +digits from other scripts. + +**Rule** The permissive local parser is never the right one here. Each port +carries tests for the shapes it would wrongly accept +(`a_trailing_newline_is_a_bad_value_for_every_strict_parser`, +`digitsFromOtherScriptsAreABadValue`, +`only_plain_ascii_digits_are_a_page_number`). + +### Patterns are anchored by hand, with `\z` + +`Planning/NameMatcher.cs`: `new Regex($"^(?:{raw})\\z")`. + +Two reasons, and a port needs both. `Regex.IsMatch` *searches*, so an +unanchored pattern would match a substring --- hence the explicit `^` and the +wrapping group, which also stops a top-level `|` in a user pattern from +escaping the anchors. And `$` is not `\z`: `$` matches before a trailing +newline, so `5\n` would satisfy a pattern anchored with `$` and must not. + +**Rule** Reproduce `\z` semantics: end of input, no trailing-newline +allowance. A regex engine whose "match whole string" mode means `$` is the +wrong tool. See `traps-python.md` and `traps-cpp17.md`, which hit this from +opposite directions. + +--- + +## Exceptions and control flow + +### An exception filter decides before the stack unwinds + +`Commands/ConvertCommand.cs`, `Commands/ExtractCommand.cs`: +`catch (Exception error) when (!(error is CliError))` and +`catch (EngineException error) when (error.Error == EngineError.Cancelled)`. + +A filter that returns false means *this handler never ran*: the exception keeps +going with its stack intact, and nothing in the handler's body happened. + +**Rule** A language without filters must catch, test, and rethrow --- and the +rethrow must not run any of the handler's side effects first, and must not +replace the original exception or its stack. Getting this subtly wrong turns a +`CliError`, which carries its own exit code, into a per-document failure with a +different one. + +### `Exception.Message` is never null + +The framework supplies a default, so the reference interpolates the message +directly into `path: code: message`. Java's `getMessage()` is null for most +exceptions thrown without one, and `"x: " + null` prints `x: null` +(`traps-java.md`). + +### `using` on a null reference disposes nothing + +It is a no-op, not an error (`traps-python.md`). + +### `HashSet.Add` reports whether the item was new + +`Planning/OutputPlanner.cs`, where the planner asks +`!seen.Add(CollisionKeyFor(key, fileSystem))`. The return value *is* the +collision detection. A port whose set-add returns +nothing has to ask separately, and has to ask before adding. + +--- + +## Console and streams + +### `WriteLine` appends the host's terminator and leaves the text alone + +The most expensive entry in this file. `Console.WriteLine` adds +`Environment.NewLine` and does not touch what it was given, so a `\n` *inside* +engine text stays a lone LF even on Windows. An engine string really does carry +them: an option description in the options catalogue is several lines of +Markdown table. + +C++17's text-mode `std::cout` translated both, which produced 41 bytes of drift +across `docfilters options` alone and a CRLF in every line of every JSON and +`--dry-run` plan. Four suites were green while it did so --- the conformance +fixtures collapse whitespace, the unit suites drive a recording console, and +the end-to-end checks assert properties. Only comparing the implementations +against each other found it. + +**Rule** Turn the platform's newline translation off and write the terminator +explicitly. Both streams: `Console.Error.WriteLine` follows the same rule. +`cpp17/src/Runtime/SystemConsole.cpp` and the Python and Java ports all do +exactly this. + +### The standard output stream is bytes, and a wrapper over it closes safely + +`Commands/ConvertCommand.cs`: a `StreamWriter` with `AutoFlush = true` is built +over it and goes out of scope. Disposing that writer leaves stdout usable for +everything afterwards, and nothing in the byte path is ever translated. + +**Rule** Where closing a wrapper would close the real descriptor, wrap it in +something whose close only flushes (`traps-java.md`). + +### `new StreamWriter(stream)` is UTF-8 with no byte order mark + +The default. A port that writes a BOM, or writes the platform's code page, +differs in the first three bytes of every text file. + +### Redirection is asked per stream + +`Console.IsOutputRedirected` and `Console.IsErrorRedirected` are separate +questions, and `--color` is decided per stream from them. A language that can +only ask about the pair together cannot reproduce `2>log` leaving stdout a +terminal; Java says so in its own list rather than pretending otherwise. + +### A line ends on CR, LF or CRLF + +`StreamReader.ReadLine` and `File.ReadAllLines`, which is how a `--list` file is +read. Not `\n` alone, and not a split that also breaks on the other separators +Unicode defines --- Python's `str.splitlines()` breaks on several more +(`traps-python.md`). + +--- + +## Filesystem + +### `Path.ChangeExtension` replaces after the last dot + +`Execution/CanvasConversion.cs`. `ChangeExtension("page.unknown", "png")` gives +`page.png`; a filename with no dot gains one; a null extension removes it. +`os.path.splitext` is not the same function (`traps-python.md`). + +### `File.Move(from, to, overwrite: true)` replaces on every platform + +`Runtime/SystemFileSystem.cs`. The .NET overload is platform-uniform. +`os.rename` refuses an existing destination on Windows; +`std::filesystem::rename` does replace, which `traps-cpp17.md` records as a +verified non-trap. + +### `FileAttributes.ReparsePoint` covers junctions as well as symlinks + +`Runtime/SystemFileSystem.cs:69`. This is the link test the whole +write-through-a-link guard rests on, and it is wider than it looks: a Windows +junction sets the attribute, while `os.path.islink` returns False for one +(`traps-python.md`). A port that asks only "is this a symlink?" has a hole on +Windows. + +### `EnumerateFileSystemEntries` is lazy + +`Runtime/SystemFileSystem.cs`. The case probe stops at the first match rather +than reading the whole directory, which matters on a directory with many +entries. + +--- + +## What looks like contract and is not + +Recorded here because each has been mistaken for drift at least once. + +- **`--help` layout.** Excluded by `tests/conformance/README.md` from when each + implementation's parsing library rendered usage its own way. None of the four + has a parsing library now, so the layout is this tool's own and the same + everywhere, but it is still not contract: help text is the one surface a + reader is expected to improve, and pinning it byte for byte would make a + reworded line a four-implementation change. `help --json` *is* compared, + because it renders from the shared argument table instead. +- **`--time`, `--progress`, `--logmem`, `-x`, `--debug-measure-io`.** Figures + that differ every run, or that measure the implementation rather than the + contract. `Recorder.NOT_COMPARED` in `tests/e2e/end2end.py` lists them with + the reasoning. +- **The peak-memory number.** `Process.PeakWorkingSet64` includes the engine's + native allocations. Java has no equivalent and uses a documented lower bound. +- **A docpack's bytes.** `df-core.xml` stamps `` to the millisecond, so + two packs of one document differ even from the same binary. +- **The tool's own version string.** No longer a trap, and worth saying why: it + used to be the four-component assembly version, which no other language could + reproduce. `VERSION.txt` is now the single source for all four ports, and + `docfilters version`'s first line *is* compared. + +--- + +## Verified non-traps + +Things about the reference that look like the list above and are not. + +- **`.Trim()` with no argument is not culture-sensitive.** A port does not need + an invariant variant of it. It needs the same *set* of characters, which is + the entry above. +- **Enum `ToString()` is not localisable.** .NET returns the identifier + whatever the culture, so the lowercased name is stable across machines. +- **`string.Split(char)` keeps empty entries.** That is the default, and the + reference relies on it where it splits argument templates on `|` and list + values on `;` and `,`.

Same +property, different route. + +**Rule** Do not add a predicate overload to the harness for one test; loop. The +production side needs no deviation: a `String` is UTF-16 units as in C#, so +`JsonWriter.escape` mirrors the reference with `Character.isSurrogate`. + +### The test harness has no `[Theory]` + +**C#** `A_dash_token_that_is_not_an_option_spelling_is_a_path` is a `[Theory]` +with five `[InlineData]` rows. **Java** the JDK-only runner has no +parameterised form, so `aDashTokenThatIsNotAnOptionSpellingIsAPath` is one +test that loops over the same five tokens.

See +`runtime/SystemConsole.java`. + +--- + +## Numbers and dates + +### The binding's dates are `java.util.Date` + +**C#** a subfile's timestamp is a `DateTime`, and "none" is +`DateTime.MinValue`. **Java** it is a `Date` built from the engine's +broken-down local time, and "none" comes back in the year 1900 or before. + +**Rule** Convert through the default zone to a `LocalDateTime`, which recovers +the engine's fields, and treat a year of 1900 or earlier as no timestamp. See +`engine/DocumentFiltersEngine.java`. + +### A bookmark's page is in its destination + +**C#** the reference reads a bookmark's page index from the binding. **Java** +the binding has no such property; the index is in the destination string. + +**Rule** Parse it from the destination, and treat a destination without one +as no page. See `engine/DocumentFiltersEngine.java`. + +--- + +## The binding's gaps + +These are calls the reference makes that the Java binding does not expose. +Each is either composed from what it does expose, or reported. + +- **No `getFileCapabilities`.** Composed from the three booleans the binding + does give; those are the only bits anything above the engine seam reads. See + `engine/DocumentFiltersEngine.java`. +- **No way to set the temporary directory.** `--temp-dir` is accepted and + ignored, because it moves the engine's scratch files and never changes an + output. See `engine/DocumentFiltersEngine.java`. +- **A docpack writer newer than its native library.** The jar in + `bindings/java/lib` declares `MakeDocPack`, but the 26.3 release's + `ISYS11dfjava` has no entry point for it, and the JVM only finds that out on + the first call, as an `UnsatisfiedLinkError`. Against that release + `--to docpack` fails each document with `E_DOCUMENT_FAILED: this binding's + native library cannot write a docpack`, and the two end-to-end docpack + checks fail; against a native library that has the entry point, both pass + and the pack matches the reference's in everything but its `` + stamp. See `docPack` in `engine/DocumentFiltersEngine.java`. +- **No native peak memory.** The reference reads `PeakWorkingSet64`. On Linux + `VmHWM` is the same measure; elsewhere the fallback is the JVM's own pools, + a lower bound, so `--max-memory` fires late, never spuriously. See + `execution/PeakMemory.java`. + +--- + +## Modules and the native boundary + +### `System.loadLibrary` searches `java.library.path` only + +**C#** the reference can point the binding at a directory at run time, which +is what `--library` and `DF_PATH` do. **Java** the binding's static +initialiser loads both `ISYS11df` and `ISYS11dfjava` by name, and the JVM +searches only `java.library.path`, fixed at start-up. Neither option can +choose the library. + +**Rule** The launcher sets the property: `DOCFILTERS_OPTS` for the +distribution's start script, a system property for `gradle run`. The start +script strips backslashes on Windows, so the path is written with forward +slashes. See `java/build.gradle.kts` and the Java launcher in +`tests/e2e/end2end.py`. + +### `--debug-measure-io` alone still buffers the file + +**C#** the reference counts I/O on a seekable file stream. **Java** +`IFileSystem.openRead` returns a stream that cannot seek, and the engine needs +to. + +**Rule** Buffer the document in memory and count what the engine asks for; +the figures are the engine's requests, not the disk's, so they are unchanged. +See `execution/DebugInput.java`. + +--- + +## Console and process + +The JDK sees less of the terminal than .NET does. Each of these is a +documented limit of the port rather than a translation bug. + +- **Only stdin and stdout together can be asked about.** `System.console()` + is non-null only when both are a terminal, so stderr is taken to be one + exactly when they are; with only stderr redirected, the error file still + gets colour codes. From Java 22 a console exists even when redirected, and + `Console.isTerminal()` is asked first, reflectively. See + `runtime/SystemConsole.java`. +- **`readPassword` has no cancel key and no echo.** Escape is an ordinary + character; only end of input cancels.

The +order of the clauses is the filter: `except CliError: raise` first, then +`except Exception`, so a usage error, a limit or an interrupt is not restated +as this document's failure. A condition on the exception's contents (the +engine's `CANCELLED`) becomes an `if` inside the clause, with the other branch +written out, because there is no falling through to the next clause. + +**Rule** Translate each `when` into clause order or an explicit branch, and +re-raise with a bare `raise` so the original traceback survives.

See `_claim` in +`execution/subfile_extraction.py`. + +### A reference name may already be a builtin + +**C#** `InterruptedError` is the reference's own class. **Python** has a +builtin `InterruptedError` (an `OSError` for `EINTR`), so reusing the name +shadows it in that module and means something else everywhere else. + +**Rule** Rename and say so where the class is defined: the port's is +`RunInterruptedError`. See `runtime/interruption.py`. + +--- + +## Text and encoding + +### `str.lower()` and `str.swapcase()` are Unicode-aware + +**C#** the reference folds A-Z alone for tokens (`--to`, option names) and +flips A-Z/a-z alone when probing a directory's case rules. **Python** +`str.lower()` folds the Kelvin sign to `k` and turns some capitals into two +characters; `str.swapcase()` flips the whole of Unicode, so the probe would +look for a different name than every other port. + +**Rule** Write the ASCII fold out character by character. See `fold_token` in +`configuration/value_parsers.py` and `_flip_case` in `runtime/case_probe.py`. + +### `str.isspace()` and `str.strip()` include four characters .NET does not + +**C#** `char.IsWhiteSpace` and `string.Trim()`. **Python** also counts +U+001C-U+001F (the information separators) as whitespace, so an entry ending +in one is a different token here than in the other ports. + +**Rule** Subtract those four from Python's answer rather than writing a table +of Unicode whitespace. See `is_whitespace` and `trim` in +`configuration/value_parsers.py`. A character-set trim such as `Trim(';')` is +not affected; see "Verified non-traps". + +### `str.splitlines()` breaks on more than line feeds + +**C#** reading a list file line by line breaks on CR, LF and CRLF. +**Python** `str.splitlines()` also breaks on vertical tab, form feed, U+001C- +U+001E, U+0085, U+2028 and U+2029, several of which are legal in a filename, +so a `--files-from` entry naming one would become two paths. + +**Rule** Split on `'\n'` and drop the final empty element. See +`read_all_lines` in `runtime/system_file_system.py`. + +### A text stream translates `'\n'` on Windows and uses the locale encoding + +**C#** `new StreamWriter(stream)` writes UTF-8 with no byte order mark and +writes `'\n'` as `'\n'`. **Python** `io.TextIOWrapper` defaults to the +locale's encoding (cp1252 on a typical Windows machine) and to translating +every `'\n'` into the host's line ending. Document text written that way is +correct and its bytes are not, on Windows only. + +**Rule** `encoding='utf-8', newline=''` on every text stream that carries a +payload, and `reconfigure(newline='')` on the console streams. See +`_text_writer` in `commands/convert_command.py`, `execution/text_conversion.py`, +`runtime/system_console.py`. + +### A lone surrogate cannot be written literally + +**C#** `JsonWriter.Escape` walks UTF-16 units, writes a well-formed pair +literally and escapes an unpaired unit as `\uXXXX`, so it has to look at the +neighbouring unit (`IsPaired`). **Python** a `str` holds code points: a real +pair is one character above U+FFFF, and any code point in U+D800-U+DFFF is +unpaired by construction. So no `IsPaired` is translated, and a pair spelled +as a high and a low surrogate escape in the source is two lone code points here, escaped where +C# would write the emoji. Left literal, the UTF-8 encoder raises +`UnicodeEncodeError`. + +**Rule** `ord(c) < 0x20 or 0xD800 <= ord(c) <= 0xDFFF` and no look-behind. See +`JsonWriter.escape` in `runtime/json_writer.py`. + +--- + +## Numbers and patterns + +### `int()` and `str.isdigit()` accept what `int.TryParse` rejects + +**C#** `int.TryParse(text, NumberStyles.None, InvariantCulture, out value)` +accepts ASCII digits only, within `Int32`. **Python** `int()` accepts +`" +5 "`, `"5_0"` and non-ASCII digits; `str.isdigit()` accepts non-ASCII +digits too; and Python integers have no upper bound, so an overflow that is a +usage error in C# is accepted here and fails somewhere further in. + +The same difference sits in the Python binding itself, which parses a +bookmark's page index with a bare `int()` where the .NET binding uses +`int.TryParse`, so a malformed destination gives `-1` in one and a number in +the other. + +**Rule** Match `^[0-9]+\Z` and state the bounds (`2147483647`). See +`configuration/value_parsers.py` and `_try_parse_int` in +`engine/document_filters_engine.py`. + +### `$` matches before a trailing newline + +**C#** the reference rejects `"5\n"`. **Python** `re`'s `$` also matches +immediately before a final `'\n'`, so `^[0-9]+$` accepts it. + +**Rule** `\Z` for the end of the string. See `configuration/value_parsers.py`. + +--- + +## Filesystem + +### `os.rename` refuses an existing destination on Windows + +**C#** `File.Move(source, destination, overwrite: true)` replaces on every +platform. **Python** `os.rename` replaces on POSIX and raises +`FileExistsError` on Windows. + +**Rule** `os.replace`. See `move_file` in `runtime/system_file_system.py`. + +### `os.path.splitext` is not `Path.ChangeExtension` + +**C#** `Path.ChangeExtension("page.unknown", "png")` and +`ChangeExtension(".unknown", "png")` both replace what follows the last dot. +**Python** `os.path.splitext` treats a leading dot as part of the name, so +`.unknown` has no extension and would become `.unknown.png`. + +**Rule** Find the last dot after the last separator yourself. See +`_change_extension` in `execution/canvas_conversion.py`. + +### `os.path.islink` does not see junctions + +**C#** the reference tests `FileAttributes.ReparsePoint`, which is set on +symlinks and junctions alike. **Python** `os.path.islink` reports symlinks +only, so a junction is walked into, and `-L`/`--follow` can recurse forever on +Windows. + +**Rule** `islink` or the reparse-point attribute, and `os.path.lexists` first +so a dangling link still counts as a link. See `is_symbolic_link` in +`runtime/system_file_system.py`. + +### `os.listdir` reads the whole directory + +**C#** `EnumerateFileSystemEntries` is lazy, and the case probe stops at the +first name with a letter in it. **Python** `os.listdir` builds the full list +first, so a directory of a hundred thousand files costs a hundred thousand +entries to answer a question one settles. + +**Rule** `os.scandir` inside a `with`, and pass a generator on. See `_probe` +in `runtime/system_file_system.py`. + +--- + +## Tests + +### unittest has no `Theory` + +**C#** an xUnit `[Theory]` with one `[InlineData]` per case is reported as one +test per case, under one name. **Python** `unittest` cannot parametrise a +method, and generating a method per case would give names the C# does not +have, which `compare_inventory.py` would count as extra and unmatched. + +**Rule** One test under the reference's name (local casing), looping over the +cases inside `with self.subTest(...)`, so each case still fails separately. See +`test_a_dash_token_that_is_not_an_option_spelling_is_a_path` in +`tests/python/unit/argument_binding_tests.py`. + +--- + +## Modules and the native boundary + +### Importing the binding at module scope breaks the pure suite + +**C#** referencing the binding's types costs nothing until one is constructed. +**Python** a top-level `import DocumentFilters` fails when the package is +absent, and `program.py` imports the module that chooses the engine, so the +whole unit suite would need the binding installed to run. + +**Rule** Import the binding inside the function that first needs it, and keep +every module above the engine seam free of it. See the "THE IMPORT IS LAZY" +banner in `engine/document_filters_engine.py`. + +### A closure captures the variable, not its value + +**C#** a `foreach` variable is a fresh binding each iteration, so a lambda +built inside the loop captures that iteration's value. **Python** a closure +captures the variable, so a lambda built inside `for definition in +definitions` sees whichever definition the loop finished on. + +This file used to pay for that. Registering arguments against `argparse` built +one deferred applier per argument, and a lambda written inline in the loop +would have made every applier set the last argument, silently ignoring every +other option on the command line. `_make_applier` existed only to give each +closure its own values by passing them as parameters. + +Both are gone: with no parser to defer to, `_apply` reads the values it needs +in the loop body and no closure is built at all. The trap is recorded anyway, +because the construct it bites is the one a translator reaches for whenever the +reference writes a lambda inside a loop, and the reference writes several. + +**Rule** Never capture a loop variable in a Python closure that outlives the +iteration. Pass it as a parameter to a factory, or do the work in the loop. + +### Import cycles are resolved at call time, not at compile time + +**C#** classes in one assembly may refer to each other freely. **Python** a +cycle of module-scope imports fails or yields a half-initialised module, +depending on which module is imported first. + +**Rule** Break a cycle at its single call-time edge with a deferred import, +and say where in a comment so the next import does not reintroduce it. See +`commands/convert_command.py`, `commands/meta_command.py`, +`execution/extractor_open_settings.py`. + +### There is no `Stream.Null` + +**C#** `Stream.Null` is a sink the framework provides. **Python** `os.devnull` +is a path, not a stream. A stand-in that pins its position at zero also breaks +the binding's stream bridge, which answers every engine seek with `tell()`. + +**Rule** A write-only sink that tracks its position. See `_NullStream` in +`execution/canvas_conversion.py`. + +--- + +## Verified non-traps + +Things that look like the list above and are not defects. + +- **`str.strip(';')` is `Trim(';')`.** Both are character-set trims; neither + touches whitespace, so an option string ending in a space keeps it in both. + See `execution/canvas_conversion.py`. +- **A `dict` keyed by `str` compares ordinally.** That is what the reference's + dictionaries are built with, and Python has no culture-sensitive comparison + to opt out of.

Read it before porting the whole tool into a fifth +language, and before moving a one-line change from the reference into the three +ports.

A behaviour implemented first in `cpp17/` and back-filled into +`csharp/` is drift that happens to point the other way. + +The second half is about what travels with it. A change to the reference's +behaviour has to leave behind something a port can be *moved by* and *checked +against*, because a port translated from code alone has nothing to verify +itself with. There are three places that something can live, and which one +depends on what the change is: + +| Where the behaviour is pinned | Covers | +| --- | --- | +| `tests/conformance/` | the CLI surface: arguments, the resolved plan, messages, exit codes, `--out-name` rendering, the format catalogue | +| the reference's own suite, `tests/csharp/` | everything below the planning seam, against a fake engine and an in-memory filesystem --- most of `Execution/` | +| `tests/e2e/end2end.py` | behaviour only the real engine shows: a call it rejects, an option that never arrives, a file written but blank | + +**Most changes do not reach the fixtures**, for two separate reasons, and it +is worth knowing which one applies. + +They describe the CLI surface, so a fix inside the page loop, a correction to +how a subfile name is derived or a stricter check on an engine return code +changes nothing they say --- writing those in would make the contract a +changelog. And `tests/conformance/README.md` scopes them to stages 1 to 3: +argv to a resolved plan, run through `--dry-run` with nothing executed, so +everything below that is invisible to them by design. Either way, if the +change is in `Execution/`, the shared fixtures are the wrong tool and a +reference unit test or an end-to-end check is the right one. + +What is not negotiable is that *something* goes with the change. The fixtures +are the strongest of the three, where they apply, because they are written by +hand from what the tool is meant to do rather than generated from the +reference: a file dumped from `csharp/` could only prove the others agree with +it, and would never catch an argument nobody implemented. A case in +`tests/conformance/` gives the port a definition of done that is not "it looks +right" --- *make these cases pass*. +A reference unit test is weaker but still translatable, which is the property +that matters. + +`end2end.py` is the third and is worth knowing early, because it is where a +good deal of real behaviour gets pinned. It runs a built CLI as a subprocess +against a real document and the real library, so it sees what no fake can; +`--cli` points it at any of the four, so one suite covers all of them. It is +also the recorder the parity comparison reads --- see the rings below. + +`.github/workflows/cli.yml` has a `contract-order` job enforcing exactly this: +it fails a pull request that changes one implementation's source without +touching either the shared fixtures or that language's own tests. Either +satisfies it. It is soft --- the `contract-unchanged` label overrides it, +because a refactor or a crash fix legitimately pins nothing new. The point is +to make the rule visible at the moment it is being broken, not to win the +argument. + +--- + +## Porting a whole tool + +### 1. Read the contract before the code + +Start with `tests/conformance/`, not with `csharp/`. +Reading the reference first teaches you one implementation's choices and leaves +you unable to tell which of them are contract. Reading the fixtures first +teaches you what is *required*, and the reference then reads as one way of +satisfying it. + +`tests/conformance/README.md` scopes what the fixtures do and do not cover. +They stop at the plan: argv to a resolved plan, a message and an exit code. +Everything below that --- the engine calls, the page loop, the bytes written +--- is yours to get right by other means, which is what the rest of this file +is about. + +### 2. Port in dependency order, pure stages first + +The folder layout is the order: + +``` +Runtime/ -> Configuration/ -> Planning/ -> Discovery/ -> Engine/ -> Execution/ -> Commands/ -> Cli/ +``` + +Everything up to `Engine/` is pure: no engine, no filesystem, no console. It is +the half that can be finished and tested before the binding is involved at all, +and the half where a translation error is cheapest to find. Each of the three +ports took roughly this shape, and each found the pure half to be the larger +one. + +`Engine/` is the seam, and it is the one place that names a binding type. Each +member maps to exactly one Document Filters call, so the question "does this +binding expose that call?" is asked once per member rather than discovered +halfway through `Execution/`. Where a binding does not, say so in that port's +traps file under a gap heading, and compose it from what the binding does +expose or report that it cannot --- do not silently do something else. + +`Cli/` **was** the one folder allowed to look unlike the reference, because +each implementation held whatever argument parser its own published samples +already used, behind the shared hand-written argument table. None of them has +a parser now, so it is a translation like any other and the rule above applies +to it in full. The table is still the contract; binding argv against it is now +shared logic rather than a per-language detail. + +### 3. Mirror the source file for file; mirror the tests name for name + +**Translate the source, don't rewrite it.** Same folders, same file names +transliterated to the language's convention, same type and member names, same +order within a file. The reason is mechanical: it has to be possible to put two +implementations side by side and diff them by eye, and every departure costs +that for the whole life of the file. + +**The tests are held to a weaker rule, on purpose: the names, not the +layout.** What must hold is that every case in `tests/csharp/` has a +counterpart in every port, under the same name in the local casing. That is +what `tests/parity/compare_inventory.py` checks, and it is what tells a +translated suite from one that quietly dropped a third of its cases. A port +may have *more* tests --- a language's own quirks need their own --- but never +fewer. + +Where a case *lives* is the local suite's business, and the four already +differ. C++17 has a `Unit/StringsTests.cpp` with no counterpart at all, +because the reference gets `Trim` and `ReadAllLines` from its framework and +has nothing to test. Java files its engine-adapter tests outside the test +package entirely, beside the code they exercise. Python has a `fakes/` +package where C# has a `Fakes/` folder of a different shape. None of this is +drift. + +`compare_inventory.py` says so itself and explains why: it records each test's +class or file as a *scope*, uses it only to tell two same-named tests apart, +and never compares scopes between languages --- "C++17 files its fixture tests +where C# files them under another class, and demanding those line up would +reject 25 pairs that are correctly matched today." + +### 4. Deviate out loud or not at all + +Sometimes the local language cannot do what the reference does. More often it +can, by another route --- a different construct, a different type, a test that +has to be written differently to pin the same thing. Both are deviations, and +reading the rule as being about the first kind is how the second kind goes +unrecorded: the behaviour matches, so nothing feels like it was given up, and +the next translation meets the same fork with nothing to go on. + +Every deliberate difference is written down twice, at the moment the choice is +made, because it has two readers who never meet. + +A **comment**, beside the code, saying what the reference does, what this does +instead, and why. That reader is looking at this line already. + +An **entry in the port's traps file**, in the same change. That reader is +translating the *next* change into this port and has no reason to open the file +your comment is in. Three traps files exist because somebody wrote both at the +time; none of them was ever assembled afterwards by going back through the +comments, and nobody is going to. A difference recorded only as a comment is +one the following translation meets cold and resolves its own way. + +A gap --- something the port cannot do at all --- is written down in one of two +further places, and neither of them is a deletion. + +A **unit test the port cannot express at all** gets a line in +`tests/parity/port-exemptions.txt` naming the language, the test and the +reason. `compare_inventory.py` reads it, and fails if the port turns out to +have that test after all. + +An **end-to-end check the port cannot run** --- because the call its binding +needs does not exist --- is left out of the run instead. `end2end.py` takes +`--skip "="`, repeatable, and both the printed report and +the recorded transcript carry the reason, so `compare.py` can tell a +deliberate skip from a check that went missing. The skips in force today are +in the "Record each implementation" step of `.github/workflows/cli.yml`, with +a comment explaining each: at the time of writing, two Java checks that need a +`MakeDocPack` entry point the pinned engine release does not export. + +A skip is verified rather than trusted. The check still runs, with its +commands kept out of the transcript so they have nothing to be compared +against, and a skip whose check *passes* fails the run and names the waiver +to delete. This is the same rule `port-exemptions.txt` has always had, and it +is what stops a waiver outliving the gap it was written for --- the engine +release that closes one of those two Java skips will not announce itself. + +### 5. A faithful port is also a review + +Re-deriving a behaviour in another language is the most thorough review the +reference ever gets. The C++17 port found twenty defects in it, eight of them +silent data loss. The Python and Java ports found more. + +When the reference turns out to be wrong, fix it **in the reference**, with the +fixtures, and let the fix reach the other ports the normal way. Do not quietly +do the right thing in the new port and leave the reference wrong --- that is +drift with good intentions. Say what you found in the change that fixes it, +where the fix is the evidence. + +--- + +## Verify in widening rings + +Each ring sees something the one inside it cannot. Run them in this order, +because the inner ones are fast and localise a failure, and the outer ones only +tell you that something, somewhere, differs. + +| Ring | What it proves | Blind to | +| --- | --- | --- | +| **1. The port's own unit suite** | the translation of each unit, against a fake engine and an in-memory filesystem | anything the translation dropped --- a missing test is simply absent | +| **2. `tests/conformance/`** | this implementation agrees with the shared contract: argv, plan, message, exit code | everything below the plan: nothing is executed | +| **3. `tests/parity/compare_inventory.py`** | the suite was translated whole --- every reference test has a counterpart here | whether the tests *pass* for the same reason | +| **4. `tests/e2e/end2end.py`** | the real engine, real files: a call the engine rejects, an option that never arrives, a file written but blank | equality --- each check asserts a property, and two implementations can satisfy all of them while disagreeing | +| **5. `tests/parity/compare.py`** | the implementations agree byte for byte on every command the end-to-end suite runs | anything that suite does not run, and any input the corpus does not contain | + +Ring 5 is the only one that compares the implementations to *each other*, and +it is the one that found the C++17 port writing CRLF where the reference writes +bare LF --- in output the four inner rings had already approved. + +Ring 5 is also not a backstop. It compares the commands the end-to-end suite +happens to run, against the documents the corpus happens to hold. A difference +that needs an input nobody committed is invisible to all five: that is how the +C++17 port came to trim six ASCII characters where the reference trims +twenty-five, with a green suite in every ring. Widening the corpus is the only +fix for that class, and it is cheaper than it sounds. + +--- + +## Moving one change + +The common case, and the one the sync workflow automates. The whole method +above compressed into what a single delta needs: + +1. **Decide where the behaviour gets pinned.** If the change alters the + command line, it starts in `tests/conformance/`. If it alters behaviour + below the + planning seam, it starts in a reference unit test, an end-to-end check, or + both --- see the table at the top. If it alters no behaviour at all --- a + refactor, a crash fix, a comment --- there is nothing to pin: say so with + the `contract-unchanged` label. It still gets ported --- that is step 3, + and the label does not excuse it. +2. **Change the reference**, if not done already, and make the new cases pass + there first. +3. **Translate into each port**, one at a time, reading that port's traps file + for the category the change touches *before* writing it. Grep the finished + diff for the constructs that file names in bold. +4. **Walk the rings** for every implementation you touched, outward. Stop at + the first failure and fix it there; an inner ring's failure explains itself, + an outer one does not. +5. **Land them together.** The four implementations are one tool, and a commit + that moves one of them is a commit that leaves the tool inconsistent. The + sync workflow handles this by having each port's pull request target the + source pull request's branch, so the contract change and all three ports + merge in one go and the default branch is never in a disagreeing state. + +### Having the agent do steps 3 and 4 + +`.github/workflows/ai-sync.yml` runs `/propagate-delta` for each port and +opens one draft pull request per language, each based on your branch. Add the +**`ai-sync`** label to start it; a maintainer has to approve the run, because +the job reads a cloud credential scoped to an environment that requires a +reviewer. It re-runs when you push to an authority path, updating the same +port pull requests rather than opening more. + +`.github/workflows/ports-landed.yml` is the other half, and the one that makes +any of this binding. It keeps a check red on your pull request while a port +pull request is still open against it, and while any port's newest commit is +older than the reference's. It measures the commits on your branch, not the +agent's run history --- so porting by hand and committing it here satisfies it +identically. The agent is a way of doing steps 3 and 4, not a different +method. + +### Two labels, two different claims + +They are easy to confuse and they do not substitute for each other: + +| Label | Says | Stands down | +| --- | --- | --- | +| `contract-unchanged` | this change needs no shared fixture and no new test | `cli.yml`'s `contract-order` | +| `ports-unaffected` | this reference change has no counterpart in the ports | `Ports landed` | + +A refactor needs both halves understood. It pins nothing new, so +`contract-unchanged` is right --- and it still has to be mirrored in the three +ports, because the whole value of the mirror is that two implementations can +be diffed by eye, and a rename that lands only in `csharp/` destroys that. So +`contract-unchanged` does **not** stand down `Ports landed`, deliberately. + +`ports-unaffected` is for the narrow case where a reference change genuinely +has no counterpart: a C#-only build detail, or a `csharp/`-only construct the +other three express differently and already express correctly. It is a claim +you sign for, and it is not the common case. It got narrower when the parsers +went --- `Cli/` used to supply most of its examples, and now mirrors the +reference like every other folder. + +--- + +## What this method is protecting + +Four implementations that agree are worth more than four that are individually +good, because the point of the sample is that a reader can pick the language +they work in and trust that what they learn transfers. Every rule above exists +because something got through without it, and the cost of a rule here is paid +once while the cost of drift is paid by every reader afterwards. diff --git a/DocFiltersCli/java/.gitattributes b/DocFiltersCli/java/.gitattributes new file mode 100644 index 0000000..f8db993 --- /dev/null +++ b/DocFiltersCli/java/.gitattributes @@ -0,0 +1,6 @@ +# The wrapper scripts are run by their own shells, which need their own line +# endings whatever core.autocrlf the checkout used: bash fails on a CR in +# gradlew, and cmd.exe misreads gradlew.bat with bare LFs. +gradlew text eol=lf +gradlew.bat text eol=crlf +*.jar binary diff --git a/DocFiltersCli/java/build.gradle.kts b/DocFiltersCli/java/build.gradle.kts new file mode 100644 index 0000000..8f35814 --- /dev/null +++ b/DocFiltersCli/java/build.gradle.kts @@ -0,0 +1,64 @@ +plugins { + application +} + +// What `docfilters version` prints on its first line, read back from the jar +// manifest at run time. +// +// ../VERSION.txt is the single source of it, as it is for the other three +// ports: the C# build reads it through Directory.Build.props, the C++17 build +// through CMakeLists.txt, and the Python package at import.

For a pip-installed binding that third answer holds +no library, and the binding is then left to look inside its own package, so a +checkout run this way needs `--library` or `DF_PATH`. + +The native libraries come from one of: + +- **A Document Filters installation** — the binary directory of the SDK as it + was installed or unpacked. +- **The C# CLI's NuGet packages** — building `csharp/DocFiltersCli.csproj` + restores Document Filters from NuGet, which puts the native libraries in + `csharp/bin/Debug/net10.0/runtimes//native/` (e.g. `win-x64` on 64-bit + Windows). The e2e tests use this path as a fallback. + +Point `DF_PATH` or `--library` at whichever directory holds them. `DF_PATH` +must be an **absolute path** — a relative one is rejected with `WinError 87: The +parameter is incorrect` on Windows, or the equivalent on other platforms. + +One exception worth knowing, and it is shared with the reference: `version` +takes no options at all, so `--library` does not reach it. `DF_PATH` does. The +built executable appears not to need either only because the libraries sit +beside it. + +## Building and testing + +There is nothing to build. + +```bash +python tests/python/run_tests.py # the whole suite +python tests/python/run_tests.py '*plan*' # a subset, by file name +python tests/python/run_tests.py PageRangeTests # or by test name +``` + +Run it from `DocFiltersCli`. A pattern is tried against file names first and, if that +matches nothing, against test ids, so a class or method name selects what it names — +and a pattern that selects nothing at all exits non-zero, rather than printing `OK` +over an empty run. + +Standard-library `unittest`, no license, no native +library, no scratch directory — the same properties the C# suite has, and for +the same reason: the engine sits behind `engine/` and the filesystem behind +`runtime/i_file_system.py`, so the tests supply their own. + +`python -m unittest discover` is deliberately not the entry point. The suite +imports both the package under test and the fakes beside it, from two +directories that no packaging step has put on the path; `run_tests.py` is those +two `sys.path` entries and nothing else. + +The suite includes the four shared fixtures in +[`tests/conformance/`](../tests/conformance), which are the authority for the +CLI surface and are run identically by every implementation. A port is done +when they pass. + +### End-to-end tests + +The end-to-end script drives any implementation from the one file: + +```bash +python tests/e2e/end2end.py # the newest built executable +python tests/e2e/end2end.py --cli python # this port, from python/ +``` + +`--cli` names the implementation: a built executable for the C# and C++17 ports, +or the directory holding this package for this one, which has no build output to +be found by. Given a directory, the script composes `PYTHONPATH` from it and the +published binding, and takes the native library out of the C# build output for +`DF_PATH`. `--binding` and `--library` override either guess. Everything else +about the run is the same for every implementation, including which checks are +skipped without a license. + +## Layout + +The modules are the reference's folders, lower-cased, holding the same things in +the same order: + +``` +python/docfilters_cli/ +├── cli/ the argument table and the argv binder +├── configuration/ the options model, value parsers, cross-argument validation +├── planning/ format catalogue, output planner, name templates, page ranges +├── discovery/ the filesystem walk +├── engine/ the Document Filters seam — the only code importing the binding +├── execution/ the Document Filters code, written against that seam +├── commands/ one thin orchestrator per verb +├── runtime/ console, filesystem, JSON writer, batch loop, exit codes +├── program.py argv in, exit code out +└── __main__.py python -m docfilters_cli +``` + +`cli/` used to be the one folder that is not a port: the reference ran on +`McMaster.Extensions.CommandLineUtils` and this on `argparse`, so only the +argument *table* was shared data. Neither has a parser now --- the four +disagreed about enough of the command line that every decision had already moved +into shared logic --- so this folder is a translation like any other, and reads +line for line against `csharp/Cli/`. + +## Where it differs from the reference, and why + +Three places, each one commented where it is: + +| | | +| --- | --- | +| `runtime/system_console.py` | The standard streams are put into UTF-8 with a replacement fallback, and their newline translation is turned off. Without the first, a report naming a document with an em dash ended a redirected run in `UnicodeEncodeError` rather than in an exit code; without the second, a line break *inside* engine text — an option description is several lines of Markdown table — came out as `\r\n` on Windows where the reference writes `\n`. UTF-8 is what .NET writes on Linux and macOS. On Windows it writes the console's code page, or the ANSI code page with no console attached, in both cases with best-fit substitution — which loses the em dash and is not reproduced here. | +| `engine/document_filters_engine.py` | `close()` tolerates exactly one message. The binding declares `Close_Instance` with `restype = None` and then checks what it returned, so every successful `Close()` raises. The tolerance is keyed on the synthesised message and nothing wider, so a real failure still raises; `tests/python/unit/document_filters_engine_tests.py` pins that. | +| a subfile's timestamp | An entry whose container records none reads as absent here and as a date in 1601 in the reference, whose `DateTime.MinValue` guard is dead code — the .NET binding turns a zero `FILETIME` into 1601-01-01 and never into `MinValue`. Deliberately not bug-compatible. The two bindings also convert differently, .NET in floating point and Python in exact microseconds, so a timestamp that *does* exist can differ in its last fractional digit. | + +Nothing else is a deliberate difference. `--help` text, the `--time` / +`--progress` / `--logmem` figures, the version strings and a docpack's +millisecond `` stamp are +[not compared across implementations](../README.md#what-is-deliberately-not-compared); +everything else is, down to the byte — verified against the reference on real +documents across every verb, every other entry of a docpack included. The two +gaps left are non-ASCII report text on Windows and the missing subfile +timestamp, and the reference is the side in the wrong in both. + +**No new dependencies.** The binding and `unittest` — the first is what the +published Python samples already depend on, the second is the standard library. +`argparse` was here too and is not any more; see `cli/` above.

Everything in tests/csharp runs against +FakeDocumentFiltersEngine and so can only check what the CLI *says* to the +engine; nothing there can catch a call the engine rejects, a flag the binding +discards on the way through, or an output file that is written but blank. Those +are exactly the bugs this has caught, so several checks below are regressions +rather than smoke: each names the bug it guards, and would still pass if it only +asserted "exit 0 and the file exists". + +Stdlib only, and a subprocess boundary rather than a test framework, so it runs +from a clean checkout with nothing installed and stays honest about what the +shipped executable does. + +A license key is optional. Without one the library runs in licenseless +evaluation, which permits enough to be worth running unattended -- see +LICENSELESS below for exactly what it does and does not allow. Checks the mode +forbids are skipped with a reason rather than failed, so a run with no key is +green when the tool is correct. + +One script, any implementation. --cli names which one: a built executable for +the C# and C++17 ports, or the directory holding the Python package or the Java +project for those two.

Exit 0 means they agree. + +`--repeat` is a second transcript of the *reference*. It is what makes the +comparison trustworthy — see "Nondeterminism is measured" below. Without it +nothing is masked, and the run says so in its header. + +No license needed: `end2end.py` runs licenseless by default and skips what +evaluation forbids, and the document it uses is committed beside it. A clean +checkout can do all of this. + +## What is compared + +Per invocation, per implementation: the exit code, raw stdout, raw stderr, and +a SHA-256 of every file in the scratch directory afterwards. + +Records are keyed by the check that made them plus their position within it, +not by position in the file. Position alone would misalign the moment one +implementation skipped a check the others ran, and every later record would +then be compared against the wrong one. + +**Raw bytes, never text.** Python's text mode applies universal-newline +translation, and `str.splitlines()` treats CRLF and LF as the same separator. +Either one would erase exactly the drift this suite exists to find. `compare.py` +splits on `b"\n"` and reports lines through `repr`, so a stray `\r` is visible +in the diff rather than silently equal. + +## Nondeterminism is measured, not guessed + +Before comparing anything, the reference implementation runs the command +**twice**. Whatever differs between those two runs — a timestamp, a duration, a +PID in a path — is nondeterminism rather than disagreement, and is excluded +from the comparison for that command. + +Doing this by measurement rather than by a list of regexes means a new source +of nondeterminism is handled the first time it appears, instead of the first +time it reddens a build nobody wants to debug. It is also what keeps this from +becoming a flaky gate that people learn to re-run until it passes. + +## What is deliberately absent + +**`--help` output.** `tests/conformance/README.md` excludes it from the +contract: each implementation renders usage its own way, and matching them +would mean writing a fifth renderer for all four to share. `help --json` *is* +compared, because it renders from the shared argument table rather than from +each implementation's own usage layout. + +**`--time`, `--logtime`, `--progress`, `--logmem`.** Their figures differ +every run. Listed in `Recorder.NOT_COMPARED` in `end2end.py`, which writes +`streams-not-compared ` in place of the streams while still comparing +the exit code and the output files' digests. + +The self-reproducibility pass would **not** mask them, and that is why the +list has to exist. It marks a line volatile only when two runs of the +*reference* disagree on it, so a figure that is stable within one +implementation and systematically different between them passes straight +through. A leaked `--logtime` duration broke `compare.py` exactly that way. + +**Anything `end2end.py` does not run.** The command vocabulary is that suite's, +by design. Widening parity coverage means adding a check there, which is the +same edit that widens its own coverage. + +## A check one implementation cannot run + +`end2end.py --skip "="` does not run it, and the transcript +records that it did not, with the reason. `compare.py` then knows the missing +commands are missing on purpose, and names them in its header: + +``` + java did not run 'docpack describes the document': the 26.3.0 Java native + library exports no MakeDocPack entry point +``` + +Without that line in the transcript, a skipped check and a check quietly lost +in translation look identical from here — records the reference has and the +port does not — so the skip has to be written down rather than simply not +happening. + +The reason is required, because a skip is a hole in the evidence this suite +produces and one with no reason beside it is a hole nobody can later decide to +close. It should be about something the implementation *cannot* do: a call its +binding does not reach, a platform with no such concept. A difference that +could be fixed is drift, and the gate reporting it is the gate working. + +A skip is per check, not per command, so it costs whatever else that check +covered — see the `--skip` in `.github/workflows/cli.yml`, which gives up the +PDF, PNG and text legs of a check to skip its docpack one. That is the price +of the simple version, and it is the reason a skip is worth removing as soon +as it can be. + +The same mechanism carries the skips nobody chose: a check licenseless +evaluation forbids, or one that needs a slower document than the one to hand. +Those are skipped by every implementation and so compare equal; the header +lists only the ones that are not shared. diff --git a/DocFiltersCli/tests/parity/compare.py b/DocFiltersCli/tests/parity/compare.py new file mode 100644 index 0000000..708c06b --- /dev/null +++ b/DocFiltersCli/tests/parity/compare.py @@ -0,0 +1,354 @@ +#!/usr/bin/env python3 +# (c) 2026 Hyland Software, Inc. and its affiliates.
