Transfer Failed Retry (整理失败重试)

query_transfer_history(status="failed")

From each record, extract the following key information:

• id: The history record ID
• src: Source file path
• title: The recognized title (may be incorrect)
• errmsg: The error message explaining why the transfer failed
• type: Media type (movie/tv)
• tmdbid: TMDB ID (if available)
• seasons/episodes: Season/episode info (if TV show)
• downloader: Which downloader was used
• download_hash: The torrent hash

Step 2: Analyze the Failure Reason

Common failure reasons and how to handle them:

Step 3: Delete the Failed History Record(s)

Before retrying, you must delete the old failed history record(s). The system skips files that already have a transfer history entry (even failed ones).

delete_transfer_history(history_id=<record_id>)

Step 4: Re-identify and Re-organize

Based on the failure analysis in Step 2:

Case A: Unrecognized Media (未识别到媒体信息)

1. Try recognizing the media from file path:

   recognize_media(path="<source_file_path>")
   

2. If recognition fails, try searching TMDB with keywords extracted from the filename:

   search_media(title="<extracted_title>", media_type="movie" or "tv")
   

3. Once you have the correct TMDB ID, re-transfer with explicit identification:

   transfer_file(file_path="<source_path>", tmdbid=<tmdb_id>, media_type="movie" or "tv")
   

Case B: Transfer Error (file operation failed)

Simply retry the transfer:

transfer_file(file_path="<source_path>")

Case C: Episode Recognition Issue

For TV shows where episode info couldn't be determined:

1. Use recognize_media to get better metadata
2. Re-transfer with explicit season info:

   transfer_file(file_path="<source_path>", tmdbid=<tmdb_id>, media_type="tv", season=<season_number>)
   

Step 5: Report Result

After the retry attempt, report the result:

• If successful: Confirm the file(s) have been organized correctly
• If failed again: Report the new error and suggest manual intervention
• For batch operations: Report a summary (e.g., "成功 8/10，失败 2/10")

Batch Processing (批量处理)

When multiple files from the same source fail simultaneously (e.g., 10 episodes of the same TV show all fail with the same error), the system groups them and triggers a single batch retry.

Key Optimization Rules for Batch Processing:

1. Identify media ONCE, apply to ALL files: Since batch files typically belong to the same media, perform media recognition (recognize_media) or search (search_media) only ONCE using the first file, then reuse the result (tmdbid, media_type) for all subsequent files.

2. Process each file individually for delete + transfer: Even though the media identity is shared, you must still:

   • Delete each failed history record individually
   • Transfer each file individually (they have different source paths)

3. Stop early if root cause is unfixable: If the first file fails due to an unfixable issue (e.g., missing directory configuration), skip all remaining files with the same error rather than retrying each one.

4. Process in order: Handle files sequentially to avoid race conditions.

Batch Example Flow:

# Given failed records: IDs = [42, 43, 44, 45] (4 episodes of the same show)
# All have errmsg="未识别到媒体信息"

# 1. Query all failed records
query_transfer_history(status="failed")

# 2. Identify media ONCE using the first file
recognize_media(path="/downloads/Show.Name.S01E01.1080p.mkv")
# Found: tmdb_id=789, media_type="tv"

# 3. For each record: delete history, then re-transfer
delete_transfer_history(history_id=42)
transfer_file(file_path="/downloads/Show.Name.S01E01.1080p.mkv", tmdbid=789, media_type="tv")

delete_transfer_history(history_id=43)
transfer_file(file_path="/downloads/Show.Name.S01E02.1080p.mkv", tmdbid=789, media_type="tv")

delete_transfer_history(history_id=44)
transfer_file(file_path="/downloads/Show.Name.S01E03.1080p.mkv", tmdbid=789, media_type="tv")

delete_transfer_history(history_id=45)
transfer_file(file_path="/downloads/Show.Name.S01E04.1080p.mkv", tmdbid=789, media_type="tv")

# 4. Report summary: "重试完成：4/4 成功"

Important Notes

• Always delete the old history record first before retrying. The system will skip files with existing history.
• Do not retry if the source file no longer exists (源目录不存在).
• Do not retry if the error is about missing directory configuration - this requires user intervention.
• For unrecognized media, always try recognize_media with the file path first before falling back to search_media.
• Be cautious with TV shows - ensure the correct season and episode information is used.
• For batch processing, always reuse media identification results across all files to save time and resources.
• When this skill is triggered automatically by the system, it provides the history_id(s) directly. Start from Step 1 with those specific IDs.

Example: Single File Retry Flow

# 1. Query the failed record
query_transfer_history(status="failed", page=1)
# Found: id=42, src="/downloads/Movie.Name.2024.1080p.mkv", errmsg="未识别到媒体信息"

# 2. Try to recognize the media from path
recognize_media(path="/downloads/Movie.Name.2024.1080p.mkv")
# Recognition failed

# 3. Search TMDB
search_media(title="Movie Name", year="2024", media_type="movie")
# Found: tmdb_id=123456

# 4. Delete old history record
delete_transfer_history(history_id=42)

# 5. Re-transfer with correct identification
transfer_file(file_path="/downloads/Movie.Name.2024.1080p.mkv", tmdbid=123456, media_type="movie")
# Success!
