When parsing pptx files, some shapes do not contain the `shape_type`
attribute, which causes the original code to throw an exception during
extraction, leading to failure in content extraction. This optimization
introduces handling logic for such anomalous shapes, providing a safer
and more robust processing mechanism.

### What problem does this PR solve?
Hello, I encountered a problem when trying to use a S3 backend
(seaweedfs) for storage in RAGFlow: when calling
`STORAGE_IMPL.get("bucket", "key")`, the actual request sent to S3 is
`bucket/bucket/key`, causing a `NoSuchKey` error.
I compared the code in `s3_conn.py` to `minio_conn.py` and
`oss_conn.py`, then decided to remove the `else` branch in
`use_prefix_path` method, and it works. I didn't configure `prefix_path`
or `bucket` in `s3` section of the `service_conf.yaml`.
I think this is a bug, but not sure.

### What problem does this PR solve?
If you deploy Ragflow using Kubernetes, the hostname will change during
a rolling update. This causes the consumer name of the task executor to
change, making it impossible to schedule tasks that were previously in a
pending state.
To address this, I introduced a recovery task that scans these pending
messages and re-publishes them, allowing the tasks to continue being
processed.

## 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 running graph resolution with infinity, if single quotation marks
appeared in the entities name that to be delete, an error tokenizing of
sqlglot might occur after calling infinity.
For example:
```
INFINITY delete table ragflow_xxx, filter knowledge_graph_kwd IN ('entity') AND entity_kwd IN ('86 IMAGES FROM PREVIOUS CONTESTS', 'ADAM OPTIMIZATION', 'BACKGROUND'ESTIMATION')
```
may raise error
```
Error tokenizing 'TS', 'ADAM OPTIMIZATION', 'BACKGROUND'ESTIMATION''
```
and make the document parsing failed。
Replace one single quotation mark with double single quotation marks can
let sqlglot tokenize the entity name correctly.

### Bug Description:
Unexpected `pymysql.err.InterfaceError: (0, '') `when using Peewee +
PyMySQL + PooledMySQLDatabase after a long-running `chat streamly`
operation.
This is a common issue with Peewee + PyMySQL + connection pooling: you
end up using a connection that was silently closed by the server, but
Peewee doesn't realize it's dead.
**I found that the error only occurs during longer streaming outputs**
and is unrelated to the database connection context, so it's likely
because:
- The prolonged streaming response caused the database connection to
time out
- The original database connection might have been disconnected by the
server during the streaming process
### Why This Happens
This error happens even when using `@DB.connection_context() `after the
stream is done. After investigation, I found this is caused by MySQL
connection pools that appear to be open but are actually dead (expired
due to` wait_timeout`).
1. `@DB.connection_context()` (as a decorator or context manager) pulls
a connection from the pool.
2. If this connection was idle and expired on the MySQL server (e.g.,
due to `wait_timeout`), but not closed in Python, it will still be
considered “open” (`DB.is_closed() == False`).
3. The real error will occur only when I execute a SQL command (such as
.`get_or_none()`), and PyMySQL tries to send it to the server via a
broken socket.
### Changes Made:
1. I implemented manual connection checks before executing SQL:
```
try:
DB.execute_sql("SELECT 1")
except Exception:
print("Connection dead, reconnecting...")
DB.close()
DB.connect()
```
2. Delayed the token count update until after the streaming response is
completed to ensure the streaming output isn't interrupted by database
operations.
```
total_tokens = 0
for txt in chat_streamly(system, history, gen_conf):
if isinstance(txt, int):
total_tokens = txt
......
break
......
if total_tokens > 0:
if not TenantLLMService.increase_usage(self.tenant_id, self.llm_type, txt, self.llm_name):
logging.error("LLMBundle.chat_streamly can't update token usage for {}/CHAT llm_name: {}, content: {}".format(self.tenant_id, self.llm_name, txt))
```

i use PdfParser in local(refer to this case:
https://github.com/infiniflow/ragflow/blob/main/rag/app/paper.py) like
this:
```

from ragflow.deepdoc.parser import PdfParser, ExcelParser, DocxParser,PlainParser
def logger(prog=None, msg=""):
print(msg)
class Pdf(PdfParser):
def __init__(self):
self.model_speciess = ParserType.MANUAL.value
super().__init__()
def __call__(self, filename, binary=None, from_page=0,

from timeit import default_timer as timer

self.__images__(

tbls = self._extract_table_figure(True, zoomin, True, True)
self._concat_downward()

callback(0.68, "Text merging finished")
# clean mess
for b in self.boxes:

return [(b["text"], b.get("layout_no", ""), self.get_position(b, zoomin))
for i, b in enumerate(self.boxes)], tbls
```
show err like this:
```
File "xxxxx/third_party/ragflow/deepdoc/parser/pdf_parser.py", line 1039, in __images__
self.pdf.close()
AttributeError: 'PdfReader' object has no attribute 'close'
```
i found ragflow source code use
`pdfplumber.open`（https://github.com/infiniflow/ragflow/blob/main/deepdoc/parser/pdf_parser.py#L1007C28-L1007C43）
and replace` self.pdf `with ` pdf2_read` （from pypdf import PdfReader as
pdf2_read）in line 1024
(https://github.com/infiniflow/ragflow/blob/main/deepdoc/parser/pdf_parser.py#L1024)
```
self.pdf = pdf2_read
```
---
and I found that `pdfplumber` can be used in this way：
```
file_path="xxx.pdf"
res = pdfplumber.open(file_path)
res.close()
```
but `pypdf.PdfReader` source code do not has `close` func, source code
use like this
```
with open(stream, "rb") as fh:
stream = BytesIO(fh.read())
self._stream_opened = True
```
> https://github.com/py-pdf/pypdf/blob/main/pypdf/_reader.py#L156
so I moved the `self.pdf.close` function call and fixed this problem
hoping to help the project😊
ragflow: v0.17 also encountered this problem. #1453 The task table shows
that the actual task has been completed. Since the process_msg of the
task is not synchronized to the document table, there is no progress
update on the page.
This may be caused by the lock not being released when the exception
occurs.
ragflow：v0.17同样碰到这个问题， 看task表实际任务已经完成，由于没有把task的process_msg同步给document表,
所以在页面看没有进度更新。
可能是这里异常时没有释放锁导致的。
```/api/ragflow_server.py
def update_progress():
lock_value = str(uuid.uuid4())
redis_lock = RedisDistributedLock("update_progress", lock_value=lock_value, timeout=60)
logging.info(f"update_progress lock_value: {lock_value}")
while not stop_event.is_set():
try:
if redis_lock.acquire():
DocumentService.update_progress()
redis_lock.release()
stop_event.wait(6)
except Exception:
logging.exception("update_progress exception")
++ if redis_lock.acquired:
++ redis_lock.release()

Sometimes, the **s** in **chunks (s, a)** is an empty string. This
causes the condition **if s and len(a) > 0** in the line **chunks = [(s,
a) for s, a in chunks if s and len(a) > 0]** to fail, which changes the
length of the new chunks. As a result, the final assertion **assert
len(chunks) - end == n_clusters, "{} vs. {}".format(len(chunks) - end,
n_clusters)** fails and raises a confusing error like 7 vs. 8
