You are a principal Python software engineer resolving a repository issue in `/workspace`. Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run. ## Critical Environment & Grader Rules 1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`. 2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files. 3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`. 4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks: `pytest path/to/test_file.py -k pattern -q --tb=short --no-header` If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off. 5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission. ## Execution Protocol ### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls) - The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories. - Run a single compound `run_command` with `grep -rn --include="*.py"` to locate: (a) the exact symbols, error strings, or functions from the problem description, (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and (c) the closest existing unit test files under `tests/`. ### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls) - Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests. - Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types. ### Phase 3 — Reproduce Bug in One Call (1 tool call) - Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts. ### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls) - Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`. - Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests. - **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`. ### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls) - Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`. - Run `git status --short && git diff` via `run_command`. Confirm: - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately), - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched), - Minimal, clean diff with valid imports and indentation. - Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

Problem Statement:
Additional newlines added in YAML blocks for multi-line strings
Hello!
I've observed that `_extract_yaml_block()` performs `"\n".join(raw_yaml)` without having stripped the newline character in each possible line, resulting in unwanted empty lines when parsing multi-line strings in YAML blocks.
I'll give an example. With this file:
```python
#!/usr/bin/python3
import tap.parser
tap_input = """TAP version 13
1..2
ok 1 A passing test
---
message: test
severity: fail
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
"""
parser = tap.parser.Parser()
for i, l in enumerate(parser.parse_text(tap_input)):
if i == 2:
print("{!r}".format(l.yaml_block["output"].splitlines()))
```
The output is:
```
['', 'this is a multiline', '', 'string but with tap', '', 'somehow blank lines', '', 'are added to it.']
```
Where as I expected:
```
['this is a multiline', 'string but with tap', 'somehow blank lines', 'are added to it.']
```
I will submit a PR shortly.

The user is reporting a bug in `tap/parser.py` where `_extract_yaml_block()` adds extra newlines to multi-line strings in YAML blocks. The problem is that `"\n".join(raw_yaml)` is used without stripping the newline character from each line in `raw_yaml`. I need to: 1. Locate `_extract_yaml_block` in `tap/parser.py`. 2. Create a reproduction script using the example provided. 3. Fix the bug by stripping newlines from lines in `raw_yaml` before joining. 4. Verify the fix. Let's start by locating `_extract_yaml_block` and reading the code.

The code is:
```python
def _extract_yaml_block(self, indent, fh):
"""Extract a raw yaml block from a file handler"""
raw_yaml = []
indent_match = re.compile(r"^{}".format(indent))
try:
next(fh)
while indent_match.match(fh.peek()):
raw_yaml.append(next(fh).replace(indent, "", 1))
# check for the end and stop adding yaml if encountered
if self.yaml_block_end.match(fh.peek()):
next(fh)
break
except StopIteration:
pass
return "\n".join(raw_yaml)
```
The problem is that `next(fh)` returns the line including the trailing newline character (unless it's the last line of the file and doesn't have one).
When `"\n".join(raw_yaml)` is called, it adds another newline between each line that already had a newline.
The user provided a reproduction case:
```python
#!/usr/bin/python3
import tap.parser
tap_input = """TAP version 13
1..2
ok 1 A passing test

message: test

parser = tap.parser.Parser()
for i, l in enumerate(parser.parse_text(tap_input)):
if i == 2:
print("{!r}".format(l.yaml_block["output"].splitlines()))
```
Expected: `['this is a multiline', 'string but with tap', 'somehow blank lines', 'are added to it.']`
Actual: `['', 'this is a multiline', '', 'string but with tap', '', 'somehow blank lines', '', 'are added to it.']`
Wait, why are there empty strings at the beginning and between every line?
If each line in `raw_yaml` is ` " this is a multiline\n"`, and then joined by `\n`, we get:
` "this is a multiline\n\nthis is a multiline\n..."`
Actually, the `next(fh)` might be keeping the `\n`.
And `replace(indent, "", 1)` only removes the leading indentation.
Let's reproduce it.

Reproduced.
The issue is indeed that `next(fh)` contains the newline character.
In `_extract_yaml_block`:
```python
raw_yaml.append(next(fh).replace(indent, "", 1))
```
If the line is `" this is a multiline\n"`, and `indent` is `" "`, `replace` makes it `" this is a multiline\n"`. (Wait, if indent is 3 spaces, and the line starts with 5 spaces, it leaves 2 spaces).
Wait, the output block in YAML uses `|+` which means it's a literal block scalar.
Anyway, the problem is the trailing newline.
If we change `next(fh)` to `next(fh).rstrip('\n\r')`, it should fix it.
But we should be careful not to remove trailing whitespaces that are part of the YAML content.
Wait, `splitlines()` in Python handles different types of line endings.
If we use `.rstrip('\n\r')` or `.rstrip('\n')`, we preserve trailing spaces on the line.
Let's see what `next(fh)` actually returns.
Wait, `fh` is likely an iterator over lines (like a file object).
In `Parser.parse_text`, `fh` is likely `io.StringIO(text).readlines()` or just `io.StringIO(text)`.
Let's check `Parser.parse_text` implementation.

The issue is in `_extract_yaml_block` in `tap/parser.py`.
The current implementation is:
```python
def _extract_yaml_block(self, indent, fh):
"""Extract a raw yaml block from a file handler"""
raw_yaml = []
indent_match = re.compile(r"^{}".format(indent))
try:
next(fh)
while indent_match.match(fh.peek()):
raw_yaml.append(next(fh).replace(indent, "", 1))
# check for the end and stop adding yaml if encountered
if self.yaml_block_end.match(fh.peek()):
next(fh)
break
except StopIteration:
pass
return "\n".join(raw_yaml)
```
The problem is that `next(fh)` returns the line *including* the newline character (if it's a file-like object). `raw_yaml` then contains lines with trailing newlines. Then `"\n".join(raw_yaml)` adds *another* newline between each line.
For example, if the input is:
` line1\n`
` line2\n`
`raw_yaml` becomes `['line1\n', 'line2\n']`.
`"\n".join(raw_yaml)` becomes `'line1\n\nline2\n'`.
This explains the empty lines in the output.
The fix should be to strip the trailing newline from each line before appending it to `raw_yaml`, or use a different way to join them.
Since the goal is to preserve the YAML block's internal structure (except for the leading indent), stripping only the trailing newline character is correct.
However, YAML blocks might have trailing whitespace that is significant.
Usually, `rstrip('\n\r')` or `rstrip('\n')` is safer.
But wait, `tap.parser.Parser.parse` says "Trailing whitespace and newline characters will be automatically stripped from the input lines." for regular lines.
Wait, looking at `parse`:
```python
first_parsed = self.parse_line(first_line.rstrip())
```
But for the YAML block, it's handled by `_extract_yaml_block`.
If I change:
`raw_yaml.append(next(fh).replace(indent, "", 1))`
to:
`raw_yaml.append(next(fh).rstrip('\n\r').replace(indent, "", 1))`
Wait, the indent is at the beginning.
The current code is: `next(fh).replace(indent, "", 1)`. If the line is ` line1\n`, and `indent` is ` `, it becomes `line1\n`.
If I do `next(fh).rstrip('\n\r').replace(indent, "", 1)`, it would be `line1`. Then `"\n".join(raw_yaml)` will join them correctly.
However, the `replace(indent, "", 1)` should happen BEFORE `rstrip`? No, the indent is at the start, `rstrip` is at the end.
Actually, it should be `next(fh).replace(indent, "", 1).rstrip('\n\r')`.
Wait, let's check if we should use `rstrip()` or `rstrip('\n\r')`.
`rstrip()` strips all trailing whitespace (spaces, tabs, newlines). YAML scalars can have trailing whitespace that might be significant.
The user's example is:
```yaml
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The `|+` means keep trailing newlines.
If the lines in the file are:
` this is a multiline\n`
` string but with tap\n`
` somehow blank lines\n`
` are added to it.\n`
And `indent` is ` ` (5 spaces).
`next(fh).replace(indent, "", 1)` gives `this is a multiline\n`.
`raw_yaml` = `['this is a multiline\n', 'string but with tap\n', 'somehow blank lines\n', 'are added to it.\n']`
`"\n".join(raw_yaml)` = `this is a multiline\n\nstring but with tap\n\nsomehow blank lines\n\nare added to it.\n`
If I use `.rstrip('\n\r')`:
`raw_yaml` = `['this is a multiline', 'string but with tap', 'somehow blank lines', 'are added to it.']`
`"\n".join(raw_yaml)` = `this is a multiline\nstring but with tap\nsomehow blank lines\nare added to it.`
Wait, if the last line has a newline, should it be preserved?
YAML's `|+` (keep trailing newlines) usually refers to the end of the block.
The `_extract_yaml_block` returns the content of the YAML block.
Let's see how `_extract_yaml_block` is used.
It's used in `_parse_result`:
```python
concat_yaml = self._extract_yaml_block(indent, fh)
return Result(
...
raw_yaml_block=concat_yaml,
)
```
And `Result` probably passes this `raw_yaml_block` to a YAML parser (like PyYAML).
If the `raw_yaml_block` is `this is a multiline\nstring but with tap\nsomehow blank lines\nare added to it.`, and it's part of a larger YAML string:
```yaml
message: test
severity: fail
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The `output` value should be the multiline string.
If the original file was:
```
---
message: test
severity: fail
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The parser reads:
1. ` ---` (indent is ` `)
2. ` message: test\n`
3. ` severity: fail\n`
4. ` output: |+\n`
5. ` this is a multiline\n`
6. ` string but with tap\n`
...
In `_extract_yaml_block(indent=" ", fh)`:
`next(fh)` (line 2) -> ` message: test\n`. Replace " " -> `message: test\n`. `raw_yaml = ['message: test\n']`.
`next(fh)` (line 3) -> ` severity: fail\n`. Replace " " -> `severity: fail\n`. `raw_yaml = ['message: test\n', 'severity: fail\n']`.
`next(fh)` (line 4) -> ` output: |+\n`. Replace " " -> `output: |+\n`. `raw_yaml = ['message: test\n', 'severity: fail\n', 'output: |+\n']`.
`next(fh)` (line 5) -> ` this is a multiline\n`. Replace " " -> ` this is a multiline\n`. `raw_yaml = ['message: test\n', 'severity: fail\n', 'output: |+\n', ' this is a multiline\n']`.
...
Wait, `_extract_yaml_block` is called *after* the `---` line.
In `_parse_result`:
```python
indent = peek_match.group("indent")
concat_yaml = self._extract_yaml_block(indent, fh)
```
`peek_match` is on the `---` line? No, `yaml_block_start` probably matches the `---` line.
Let's check `yaml_block_start`. It's probably defined in `__init__`.
Regardless, the problem is that `next(fh)` returns the line with the newline.
If I use `rstrip('\n\r')` it should fix it.
Let's verify with the reproduction script.
Proposed fix:
```python
- raw_yaml.append(next(fh).replace(indent, "", 1))
+ raw_yaml.append(next(fh).replace(indent, "", 1).rstrip('\n\r'))
```
Wait, what if the line is just the newline?
If the line is ` \n` (indent is ` `), `replace` makes it `\n`, `rstrip('\n\r')` makes it `` (empty string).
Then `"\n".join(raw_yaml)` will put a `\n` there.
Let's test this.
Wait, if the input is:
` line1\n`
` \n`
` line3\n`
Current behavior:
`raw_yaml` = `['line1\n', '\n', 'line3\n']`
`join` = `line1\n\n\n\nline3\n` (Too many newlines)
Proposed behavior:
`raw_yaml` = `['line1', '', 'line3']`
`join` = `line1\n\nline3` (Correct for YAML multiline)
What if the line is ` line1 \n` (trailing space)?
Current: `line1 \n`
Proposed: `line1 ` (since `rstrip('\n\r')` only removes newlines). Correct.
Let's implement the fix.

Everything seems fine.
One more check: does `_extract_yaml_block` handle empty lines correctly if they are part of the YAML?
Example:
```yaml
output: |
line1
line3
```
In the file:
` line1\n`
` \n`
` line3\n`
With my fix:
`raw_yaml` = `['line1', '', 'line3']`
`join` = `line1\n\nline3`
This is correct.
What if the file has:
` line1\n`
` \n`
` line3\n`
` \n` (trailing empty line in block)
`raw_yaml` = `['line1', '', 'line3', '']`
`join` = `line1\n\nline3\n`
This also seems correct for `|+` (keep trailing newlines).
Wait, if the YAML block ends with a newline, the `while indent_match.match(fh.peek())` will keep going as long as the indent matches.
If the last line of the YAML block is ` \n`, it matches the indent.
Then `raw_yaml.append('\n'.rstrip('\n\r'))` -> `raw_yaml.append('')`.
Then `"\n".join(raw_yaml)` will add a trailing `\n` if there is at least one element after it? No, if the last element is `''`, then `join` will end with `\n`.
Wait, if `raw_yaml` = `['line1']`, `join` is `line1`.
If `raw_yaml` = `['line1', '']`, `join` is `line1\n`.
Let's double check if this is correct behavior.
In YAML, `|+` preserves trailing newlines.
If the file is:
```
---
output: |+
line1
```
(Where there is a blank line with indent after `line1`)
The lines are:
` output: |+\n`
` line1\n`
` \n`
`_extract_yaml_block`:
1. `next(fh)` (line `output: |+\n`)
2. Loop:
- `fh.peek()` is ` line1\n`. Matches indent.
`raw_yaml.append('line1')`.
- `fh.peek()` is ` \n`. Matches indent.
`raw_yaml.append('')`.
- `fh.peek()` is `---` or EOF. Loop ends.
3. `"\n".join(['line1', ''])` -> `line1\n`.
This seems correct. If the original implementation was:
`raw_yaml.append('line1\n')`
`raw_yaml.append('\n')`
`"\n".join(['line1\n', '\n'])` -> `line1\n\n\n`
This was definitely wrong.
One last thing: `rstrip('\n\r')` vs `rstrip('\r\n')`. Order doesn't matter for `rstrip` as it treats the argument as a set of characters.
I'll just verify `git status` and `git diff`.

The issue was caused by `_extract_yaml_block` in `tap/parser.py` adding extra newlines when joining lines from the file handler, as `next(fh)` preserves the original line's newline character. I fixed this by applying `.rstrip('\n\r')` to each extracted line before appending it to the list of YAML lines. This ensures that only the intended newlines (added by `"\n".join()`) are present in the final YAML block.

Reproduced.
The issue is indeed that `next(fh)` contains the newline character.
In `_extract_yaml_block`:
```python
raw_yaml.append(next(fh).replace(indent, "", 1))
```
If the line is `" this is a multiline\n"`, and `indent` is `" "`, `replace` makes it `" this is a multiline\n"`. (Wait, if indent is 3 spaces, and the line starts with 5 spaces, it leaves 2 spaces).
Wait, the output block in YAML uses `|+` which means it's a literal block scalar.
Anyway, the problem is the trailing newline.
If we change `next(fh)` to `next(fh).rstrip('\n\r')`, it should fix it.
But we should be careful not to remove trailing whitespaces that are part of the YAML content.
Wait, `splitlines()` in Python handles different types of line endings.
If we use `.rstrip('\n\r')` or `.rstrip('\n')`, we preserve trailing spaces on the line.
Let's see what `next(fh)` actually returns.
Wait, `fh` is likely an iterator over lines (like a file object).

The issue is in `_extract_yaml_block` in `tap/parser.py`.
The current implementation is:
```python
def _extract_yaml_block(self, indent, fh):
"""Extract a raw yaml block from a file handler"""
raw_yaml = []
indent_match = re.compile(r"^{}".format(indent))
try:
next(fh)
while indent_match.match(fh.peek()):
raw_yaml.append(next(fh).replace(indent, "", 1))
# check for the end and stop adding yaml if encountered
if self.yaml_block_end.match(fh.peek()):
next(fh)
break
except StopIteration:
pass
return "\n".join(raw_yaml)
```
The problem is that `next(fh)` returns the line *including* the newline character (if it's a file-like object). `raw_yaml` then contains lines with trailing newlines. Then `"\n".join(raw_yaml)` adds *another* newline between each line.
For example, if the input is:
` line1\n`
` line2\n`
`raw_yaml` becomes `['line1\n', 'line2\n']`.
`"\n".join(raw_yaml)` becomes `'line1\n\nline2\n'`.
This explains the empty lines in the output.
The fix should be to strip the trailing newline from each line before appending it to `raw_yaml`, or use a different way to join them.
Since the goal is to preserve the YAML block's internal structure (except for the leading indent), stripping only the trailing newline character is correct.
However, YAML blocks might have trailing whitespace that is significant.
Usually, `rstrip('\n\r')` or `rstrip('\n')` is safer.
But wait, `tap.parser.Parser.parse` says "Trailing whitespace and newline characters will be automatically stripped from the input lines." for regular lines.
Wait, looking at `parse`:
```python
first_parsed = self.parse_line(first_line.rstrip())
```
But for the YAML block, it's handled by `_extract_yaml_block`.
If I change:
`raw_yaml.append(next(fh).replace(indent, "", 1))`
to:
`raw_yaml.append(next(fh).rstrip('\n\r').replace(indent, "", 1))`
Wait, the indent is at the beginning.
The current code is: `next(fh).replace(indent, "", 1)`. If the line is ` line1\n`, and `indent` is ` `, it becomes `line1\n`.
If I do `next(fh).rstrip('\n\r').replace(indent, "", 1)`, it would be `line1`. Then `"\n".join(raw_yaml)` will join them correctly.
However, the `replace(indent, "", 1)` should happen BEFORE `rstrip`? No, the indent is at the start, `rstrip` is at the end.
Actually, it should be `next(fh).replace(indent, "", 1).rstrip('\n\r')`.
Wait, let's check if we should use `rstrip()` or `rstrip('\n\r')`.
`rstrip()` strips all trailing whitespace (spaces, tabs, newlines). YAML scalars can have trailing whitespace that might be significant.
The user's example is:
```yaml
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The `|+` means keep trailing newlines.
If the lines in the file are:
` this is a multiline\n`
` string but with tap\n`
` somehow blank lines\n`
` are added to it.\n`
And `indent` is ` ` (5 spaces).
`next(fh).replace(indent, "", 1)` gives `this is a multiline\n`.
`raw_yaml` = `['this is a multiline\n', 'string but with tap\n', 'somehow blank lines\n', 'are added to it.\n']`
`"\n".join(raw_yaml)` = `this is a multiline\n\nstring but with tap\n\nsomehow blank lines\n\nare added to it.\n`
If I use `.rstrip('\n\r')`:
`raw_yaml` = `['this is a multiline', 'string but with tap', 'somehow blank lines', 'are added to it.']`
`"\n".join(raw_yaml)` = `this is a multiline\nstring but with tap\nsomehow blank lines\nare added to it.`
Wait, if the last line has a newline, should it be preserved?
YAML's `|+` (keep trailing newlines) usually refers to the end of the block.
The `_extract_yaml_block` returns the content of the YAML block.
Let's see how `_extract_yaml_block` is used.
It's used in `_parse_result`:
```python
concat_yaml = self._extract_yaml_block(indent, fh)
return Result(
...
raw_yaml_block=concat_yaml,
)
```
And `Result` probably passes this `raw_yaml_block` to a YAML parser (like PyYAML).
If the `raw_yaml_block` is `this is a multiline\nstring but with tap\nsomehow blank lines\nare added to it.`, and it's part of a larger YAML string:
```yaml
message: test
severity: fail
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The `output` value should be the multiline string.
If the original file was:
```
---
message: test
severity: fail
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The parser reads:
1. ` ---` (indent is ` `)
2. ` message: test\n`
3. ` severity: fail\n`
4. ` output: |+\n`
5. ` this is a multiline\n`
6. ` string but with tap\n`
...
In `_extract_yaml_block(indent=" ", fh)`:
`next(fh)` (line 2) -> ` message: test\n`. Replace " " -> `message: test\n`. `raw_yaml = ['message: test\n']`.
`next(fh)` (line 3) -> ` severity: fail\n`. Replace " " -> `severity: fail\n`. `raw_yaml = ['message: test\n', 'severity: fail\n']`.
`next(fh)` (line 4) -> ` output: |+\n`. Replace " " -> `output: |+\n`. `raw_yaml = ['message: test\n', 'severity: fail\n', 'output: |+\n']`.
`next(fh)` (line 5) -> ` this is a multiline\n`. Replace " " -> ` this is a multiline\n`. `raw_yaml = ['message: test\n', 'severity: fail\n', 'output: |+\n', ' this is a multiline\n']`.
...
Wait, `_extract_yaml_block` is called *after* the `---` line.
In `_parse_result`:
```python
indent = peek_match.group("indent")
concat_yaml = self._extract_yaml_block(indent, fh)
```
`peek_match` is on the `---` line? No, `yaml_block_start` probably matches the `---` line.
Let's check `yaml_block_start`. It's probably defined in `__init__`.
Regardless, the problem is that `next(fh)` returns the line with the newline.
If I use `rstrip('\n\r')` it should fix it.
Let's verify with the reproduction script.
Proposed fix:
```python
- raw_yaml.append(next(fh).replace(indent, "", 1))
+ raw_yaml.append(next(fh).replace(indent, "", 1).rstrip('\n\r'))
```
Wait, what if the line is just the newline?
If the line is ` \n` (indent is ` `), `replace` makes it `\n`, `rstrip('\n\r')` makes it `` (empty string).
Then `"\n".join(raw_yaml)` will put a `\n` there.
Let's test this.
Wait, if the input is:
` line1\n`
` \n`
` line3\n`
Current behavior:
`raw_yaml` = `['line1\n', '\n', 'line3\n']`
`join` = `line1\n\n\n\nline3\n` (Too many newlines)
Proposed behavior:
`raw_yaml` = `['line1', '', 'line3']`
`join` = `line1\n\nline3` (Correct for YAML multiline)
What if the line is ` line1 \n` (trailing space)?
Current: `line1 \n`
Proposed: `line1 ` (since `rstrip('\n\r')` only removes newlines). Correct.
Let's implement the fix.The issue is in `_extract_yaml_block` in `tap/parser.py`.
The current implementation is:
```python
def _extract_yaml_block(self, indent, fh):
"""Extract a raw yaml block from a file handler"""
raw_yaml = []
indent_match = re.compile(r"^{}".format(indent))
try:
next(fh)
while indent_match.match(fh.peek()):
raw_yaml.append(next(fh).replace(indent, "", 1))
# check for the end and stop adding yaml if encountered
if self.yaml_block_end.match(fh.peek()):
next(fh)
break
except StopIteration:
pass
return "\n".join(raw_yaml)
```
The problem is that `next(fh)` returns the line *including* the newline character (if it's a file-like object). `raw_yaml` then contains lines with trailing newlines. Then `"\n".join(raw_yaml)` adds *another* newline between each line.
For example, if the input is:
` line1\n`
` line2\n`
`raw_yaml` becomes `['line1\n', 'line2\n']`.
`"\n".join(raw_yaml)` becomes `'line1\n\nline2\n'`.
This explains the empty lines in the output.
The fix should be to strip the trailing newline from each line before appending it to `raw_yaml`, or use a different way to join them.
Since the goal is to preserve the YAML block's internal structure (except for the leading indent), stripping only the trailing newline character is correct.
However, YAML blocks might have trailing whitespace that is significant.
Usually, `rstrip('\n\r')` or `rstrip('\n')` is safer.
But wait, `tap.parser.Parser.parse` says "Trailing whitespace and newline characters will be automatically stripped from the input lines." for regular lines.
Wait, looking at `parse`:
```python
first_parsed = self.parse_line(first_line.rstrip())
```
But for the YAML block, it's handled by `_extract_yaml_block`.
If I change:
`raw_yaml.append(next(fh).replace(indent, "", 1))`
to:
`raw_yaml.append(next(fh).rstrip('\n\r').replace(indent, "", 1))`
Wait, the indent is at the beginning.
The current code is: `next(fh).replace(indent, "", 1)`. If the line is ` line1\n`, and `indent` is ` `, it becomes `line1\n`.
If I do `next(fh).rstrip('\n\r').replace(indent, "", 1)`, it would be `line1`. Then `"\n".join(raw_yaml)` will join them correctly.
However, the `replace(indent, "", 1)` should happen BEFORE `rstrip`? No, the indent is at the start, `rstrip` is at the end.
Actually, it should be `next(fh).replace(indent, "", 1).rstrip('\n\r')`.
Wait, let's check if we should use `rstrip()` or `rstrip('\n\r')`.
`rstrip()` strips all trailing whitespace (spaces, tabs, newlines). YAML scalars can have trailing whitespace that might be significant.
The user's example is:
```yaml
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The `|+` means keep trailing newlines.
If the lines in the file are:
` this is a multiline\n`
` string but with tap\n`
` somehow blank lines\n`
` are added to it.\n`
And `indent` is ` ` (5 spaces).
`next(fh).replace(indent, "", 1)` gives `this is a multiline\n`.
`raw_yaml` = `['this is a multiline\n', 'string but with tap\n', 'somehow blank lines\n', 'are added to it.\n']`
`"\n".join(raw_yaml)` = `this is a multiline\n\nstring but with tap\n\nsomehow blank lines\n\nare added to it.\n`
If I use `.rstrip('\n\r')`:
`raw_yaml` = `['this is a multiline', 'string but with tap', 'somehow blank lines', 'are added to it.']`
`"\n".join(raw_yaml)` = `this is a multiline\nstring but with tap\nsomehow blank lines\nare added to it.`
Wait, if the last line has a newline, should it be preserved?
YAML's `|+` (keep trailing newlines) usually refers to the end of the block.
The `_extract_yaml_block` returns the content of the YAML block.
Let's see how `_extract_yaml_block` is used.
It's used in `_parse_result`:
```python
concat_yaml = self._extract_yaml_block(indent, fh)
return Result(
...
raw_yaml_block=concat_yaml,
)
```
And `Result` probably passes this `raw_yaml_block` to a YAML parser (like PyYAML).
If the `raw_yaml_block` is `this is a multiline\nstring but with tap\nsomehow blank lines\nare added to it.`, and it's part of a larger YAML string:
```yaml
message: test
severity: fail
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The `output` value should be the multiline string.
If the original file was:
```
---
message: test
severity: fail
output: |+
this is a multiline
string but with tap
somehow blank lines
are added to it.
```
The parser reads:
1. ` ---` (indent is ` `)
2. ` message: test\n`
3. ` severity: fail\n`
4. ` output: |+\n`
5. ` this is a multiline\n`
6. ` string but with tap\n`
...
In `_extract_yaml_block(indent=" ", fh)`:
`next(fh)` (line 2) -> ` message: test\n`. Replace " " -> `message: test\n`. `raw_yaml = ['message: test\n']`.
`next(fh)` (line 3) -> ` severity: fail\n`. Replace " " -> `severity: fail\n`. `raw_yaml = ['message: test\n', 'severity: fail\n']`.
`next(fh)` (line 4) -> ` output: |+\n`. Replace " " -> `output: |+\n`. `raw_yaml = ['message: test\n', 'severity: fail\n', 'output: |+\n']`.
`next(fh)` (line 5) -> ` this is a multiline\n`. Replace " " -> ` this is a multiline\n`. `raw_yaml = ['message: test\n', 'severity: fail\n', 'output: |+\n', ' this is a multiline\n']`.
...
Wait, `_extract_yaml_block` is called *after* the `---` line.
In `_parse_result`:
```python
indent = peek_match.group("indent")
concat_yaml = self._extract_yaml_block(indent, fh)
```
`peek_match` is on the `---` line? No, `yaml_block_start` probably matches the `---` line.
Let's check `yaml_block_start`. It's probably defined in `__init__`.
Regardless, the problem is that `next(fh)` returns the line with the newline.
If I use `rstrip('\n\r')` it should fix it.
Let's verify with the reproduction script.
Proposed fix:
```python
- raw_yaml.append(next(fh).replace(indent, "", 1))
+ raw_yaml.append(next(fh).replace(indent, "", 1).rstrip('\n\r'))
```
Wait, what if the line is just the newline?
If the line is ` \n` (indent is ` `), `replace` makes it `\n`, `rstrip('\n\r')` makes it `` (empty string).
Then `"\n".join(raw_yaml)` will put a `\n` there.
Let's test this.
Wait, if the input is:
` line1\n`
` \n`
` line3\n`
Current behavior:
`raw_yaml` = `['line1\n', '\n', 'line3\n']`
`join` = `line1\n\n\n\nline3\n` (Too many newlines)
Proposed behavior:
`raw_yaml` = `['line1', '', 'line3']`
`join` = `line1\n\nline3` (Correct for YAML multiline)
What if the line is ` line1 \n` (trailing space)?
Current: `line1 \n`
Proposed: `line1 ` (since `rstrip('\n\r')` only removes newlines). Correct.

Everything seems fine.
One more check: does `_extract_yaml_block` handle empty lines correctly if they are part of the YAML?
Example:
```yaml
output: |
line1
line3
```
In the file:
` line1\n`
` \n`
` line3\n`
With my fix:
`raw_yaml` = `['line1', '', 'line3']`
`join` = `line1\n\nline3`
This is correct.
What if the file has:
` line1\n`
` \n`
` line3\n`
` \n` (trailing empty line in block)
`raw_yaml` = `['line1', '', 'line3', '']`
`join` = `line1\n\nline3\n`
This also seems correct for `|+` (keep trailing newlines).
Wait, if the YAML block ends with a newline, the `while indent_match.match(fh.peek())` will keep going as long as the indent matches.
If the last line of the YAML block is ` \n`, it matches the indent.
Then `raw_yaml.append('\n'.rstrip('\n\r'))` -> `raw_yaml.append('')`.
Then `"\n".join(raw_yaml)` will add a trailing `\n` if there is at least one element after it? No, if the last element is `''`, then `join` will end with `\n`.
Wait, if `raw_yaml` = `['line1']`, `join` is `line1`.
If `raw_yaml` = `['line1', '']`, `join` is `line1\n`.
Let's double check if this is correct behavior.
In YAML, `|+` preserves trailing newlines.
If the file is:
```
---
output: |+
line1
```
(Where there is a blank line with indent after `line1`)
The lines are:
` output: |+\n`
` line1\n`
` \n`
`_extract_yaml_block`:
1. `next(fh)` (line `output: |+\n`)
2. Loop:
- `fh.peek()` is ` line1\n`. Matches indent.
`raw_yaml.append('line1')`.
- `fh.peek()` is ` \n`. Matches indent.
`raw_yaml.append('')`.
- `fh.peek()` is `---` or EOF. Loop ends.
3. `"\n".join(['line1', ''])` -> `line1\n`.
This seems correct. If the original implementation was:
`raw_yaml.append('line1\n')`
`raw_yaml.append('\n')`
`"\n".join(['line1\n', '\n'])` -> `line1\n\n\n`
This was definitely wrong.
One last thing: `rstrip('\n\r')` vs `rstrip('\r\n')`. Order doesn't matter for `rstrip` as it treats the argument as a set of characters.
I'll just verify `git status` and `git diff`.Everything seems fine.
