Fix: whole knowledge graph lost after removing any document in the knowledge base (#7151)
### What problem does this PR solve?
When you removed any document in a knowledge base using knowledge graph,
the graph's `removed_kwd` is set to "Y".
However, in the function `graphrag.utils.get_gaph`, `rebuild_graph`
method is passed and directly return `None` while `removed_kwd=Y`,
making residual part of the graph abandoned (but old entity data still
exist in db).
Besides, infinity instance actually pass deleting graph components'
`source_id` when removing document. It may cause wrong graph after
rebuild.

fix(nursery): Fix Closure Trap Issues in Trio Concurrent Tasks (#7106)
## Problem Description
Multiple files in the RAGFlow project contain closure trap issues when
using lambda functions with `trio.open_nursery()`. This problem causes
concurrent tasks created in loops to reference the same variable,
resulting in all tasks processing the same data (the data from the last
iteration) rather than each task processing its corresponding data from
the loop.
## Issue Details
When using a `lambda` to create a closure function and passing it to
`nursery.start_soon()` within a loop, the lambda function captures a
reference to the loop variable rather than its value. For example:
```python
# Problematic code
async with trio.open_nursery() as nursery:
for d in docs:
nursery.start_soon(lambda: doc_keyword_extraction(chat_mdl, d, topn))
```
In this pattern, when concurrent tasks begin execution, `d` has already
become the value after the loop ends (typically the last element),
causing all tasks to use the same data.
## Fix Solution
Changed the way concurrent tasks are created with `nursery.start_soon()`
by leveraging Trio's API design to directly pass the function and its
arguments separately:
```python
# Fixed code
async with trio.open_nursery() as nursery:
for d in docs:
nursery.start_soon(doc_keyword_extraction, chat_mdl, d, topn)
```
This way, each task uses the parameter values at the time of the
function call, rather than references captured through closures.
## Fixed Files
Fixed closure traps in the following files:
1. `rag/svr/task_executor.py`: 3 fixes, involving document keyword
extraction, question generation, and tag processing
2. `rag/raptor.py`: 1 fix, involving document summarization
3. `graphrag/utils.py`: 2 fixes, involving graph node and edge
processing
4. `graphrag/entity_resolution.py`: 2 fixes, involving entity resolution
and graph node merging
5. `graphrag/general/mind_map_extractor.py`: 2 fixes, involving document
processing
6. `graphrag/general/extractor.py`: 3 fixes, involving content
processing and graph node/edge merging
7. `graphrag/general/community_reports_extractor.py`: 1 fix, involving
community report extraction
## Potential Impact
This fix resolves a serious concurrency issue that could have caused:
- Data processing errors (processing duplicate data)
- Performance degradation (all tasks working on the same data)
- Inconsistent results (some data not being processed)
After the fix, all concurrent tasks should correctly process their
respective data, improving system correctness and reliability.
### What problem does this PR solve?
when there are multiple entities, the variable `v` may be a list, which
will lead to this error:
```
| File "/mnt/d/wrf/ragflow/ragflow/graphrag/utils.py", line 59, in replace_all
| result = result.replace(f"{{{k}}}", v)
| TypeError: replace() argument 2 must be str, not list
```
this pr assign this `v` to be a str

### Related Issue: #6653
### Environment:
Using nightly version
Elasticsearch database
### Bug Description:
When clicking the "Entity Resolution" button in KnowledgeGraph,
encountered the following errors:
graphrag/entity_resolution.py
```
list(sub_connect_graph.nodes) AttributeError
```
graphrag/general/extractor.py
```
node0_attrs[attr] = sorted(set(node0_attrs[attr].extend(node1_attrs[attr])))
TypeError: 'NoneType' object is not iterable
```
```
for attr in ["keywords", "source_id"]:
KeyError I think attribute "keywords" is in edges not nodes
```
graphrag/utils.py
```
settings.docStoreConn.delete() # Sync function called as async
```
### Changes Made:
Fixed AttributeError in entity_resolution.py by properly handling graph
nodes
Fixed TypeError and KeyError in extractor.py by separate operations
Corrected async/sync mismatch in document deletion call
