Robert Nystrom c43643c813 Use escapes instead single-line strings to avoid a test_runner test being mistaken as a static error test.
This is a tweak to https://dart-review.googlesource.com/c/sdk/+/491340

Other test expectations in this file have the same problem that CL fixes and avoid it using an otherwise unnecessary escaped forward slash. This fixes that test to use the same style for consistency's sake. :)

Paul Berry 3c4f3a867e Avoid test runner confusion with triply-quoted strings.
With this change, the test runner correctly recognizes
`pkg/test_runner/test/update_errors_test.dart` as a file that's
expected _not_ to contain errors. Previously, it mistook it as a test
that was expected to contain errors, so it skipped testing it
entirely.

Robert Nystrom 82afcb4edd Make the static error test updater not write comments at column zero.
The old formatter had a special rule that if a line comment as at the
left edge of the page, it would stay there regardless of the surrounding
indentation. So if you had:

```
class C {
  m() {
// comment
  }
}
```

After formatting, the comment would still be there instead of being
indented. The intent of that was to not shift over code that had been
commented out.

But all of the IDEs I tested don't actually work that way. When they
comment out code, they tend to put the `//` at the indentation of the
surrounding code. So the new formatter doesn't have this special rule
and always indents line comments following the surrounding indentation.
This is good because it also means that code generators that don't write
any leading whitespace will still get nicely formatted comments.

However, the static error test updater took advantage of this rule and
would write static error marker comments at column zero if needed to
get the carets to align with the code on the previous line and assume
that the formatter wouldn't move the comment.

This fixes the static error test updater. It always writes comments
using indentation from the previous line of code and if the caret
doesn't fit that way, it uses an explicit column marker.

Fix #57042.

Based on abandoned change #264261.

Changes to that PR: compare and show file paths, improve part parsing, include analyzer expectations from other files as well as CFE expectations, update unit tests.

Add end to end tests. The simplest case "library_failure_test.dart" passes before this PR, all others require the change in this PR to pick up expectations in other files.

Lasse R.H. Nielsen e85042b403 Allow error test expectations to omit the implicit line.
Error tests with explicit line/column markers, like
 [error line 123, column 456]
currently require both "line" and "column".
All existing occurrences of `[error line 123, column 456]` always
refer to the most recent non-comment line *just like* the `// ^^` lines,
so omitting the line, and having the most recent non-comment line
as the *default* line, seems reasonable.

This CL makes the line optional, the new format without a "line" entry
will be just `[error column 456]`.

This allows files to change the number of lines in the code without
invalidating any later expectations.
(Or, say, remove a comment line at the top of the file!)

Omits the line entry by default when writing/updating expectations.

Robert Nystrom fdb6ca6d01 Add support for context messages to static error tests.
Currently only CFE ("Fasta") tests have their context message output
parsed. It should be easy to extend that to dart2js and DDC if that's
useful. Analyzer might be more work.

This also adds support to the test updater for inserting context
messages when updating tests. By default, that flag is off, so the
existing behavior is preserved where context messages are ignnored. If
you want them, pass "-c" when updating a test.

When validating test output, if the test file contains context messages,
then they are validated. Otherwise, any context messages in the CFE
output are ignored. This way existing tests still pass.


Change StaticError to represent a single error for a single front end.

Before, the data model collapsed errors for different front-ends at the
same location into a single StaticError object which tracked different
messages for each front end. The idea was to move towards a world where
they really are the "same" error with eventually the same message.

But this adds a lot of complexity with things like merging errors and
doesn't reflect the reality that each error from each front end is
basically its own thing. Also, critically, it makes it much harder to
attach context messages to a specific front end's error object.

This changes it so that an instance of StaticError represents a single
error for a single front end. The test file syntax is unchanged and the
updated tool behaves the same. In a static error test, multiple
expectations can still share the same "//   ^^^" marker line. They are
just expanded to multiple StaticError objects at parse time.

This eliminates all of the complexity around merging and simplifying
errors.

Jens Johansen 214cdbdc81 [test_runner] Fix RangeError when parsing static errors
Previously it tested if it was at the end of file (defined as
_currentLine >= _lines.length), if it was not it would try to read the
_next_ line (_peek(1)), meaning that if _currentLine = _lines.length - 1
it would _peek(1) and try to read _lines[lines.length] and crash with a
range error. This CL fixes it by actually checking if it can safely peek
the amount it wants to.

Robert Nystrom 1f10afc628 Don't use explicit error locations for CFE-only errors.
The CFE currently does not report the length in an error location, just
the starting position. When the static error update tool inserts an
error marker for an error reported only by the CFE, it doesn't know
what length to use.

It used to deal with this by always writing an explicit error location
like:

    // [error line 1, column 9]

Those are kind of ugly and brittle, though. This changes it to treat
the error as implicitly having length 1. This way, it can just output:

    //       ^

When validating an error expectation against a report CFE error, the
length is ignored anyway (since the CFE doesn't report it). In order to
ensure that the parsed output of the tool matches the reported data that
produced it, the parser also ignores the length when parsing an error
expectation for a CFE-only error with length one.

Fix #37991.

Robert Nystrom 48d8c00410 Handle shifted line number of static error updater.
This rarely comes into play because most static error markers don't
have an explicit line number. (This is by design so that shifts don't
cause diff churn.) But in some cases, the line number is written. When
that happens, the number may be wrong because previous added or removed
errors can shift the output line from where the original error was
reported.

Compensate for that. Fix #37990.
