rename_lock
下の方に日本語の説明があります
Overview
- Easy file exclusive locking tool based on file rename.
Usage
- While you are in "WITH" area, the file is locked and cannot be edited by any other process.
- While locked, the file will be renamed to "original_name_random_string.locked"
- The name can be obtained with rlock.filename
import rename_lock
with rename_lock("./demo_file.txt") as rlock:
# operation on locked file
temp_filename = rlock.filename # temporary file name
with open(temp_filename, "w") as f:
f.write("something")
-
About Unlocking
- The lock is automatically unlocked when exiting "WITH" area.
- Also, when using "WITH", it will automatically unlock when stopped due to an error or when stopped by ctrl+C.
- However, there may be cases where the file is not unlocked, such as when the entire window is erased.
-
The following is how to write when not using "WITH".
rlock = rename_lock("./demo_file.txt")
print(rlock.filename)
rlock.unlock()
概要
- 手軽なファイルの排他ロックツール
- ファイルの名称変更を動作原理とする
使用例
- 下記のように、with内にいる間ファイルの編集がロックされます
- ロック中はファイルは「元の名前_ランダム文字列.locked」という名前に変更されます
- その名前はrlock.filenameで取得できます
import rename_lock
with rename_lock("./demo_file.txt") as rlock:
# lockしたファイルに対する操作を書く
temp_filename = rlock.filename # temporary file name
with open(temp_filename, "w") as f:
f.write("something")
-
ロック解除について
- withを抜けると自動的にロック解除されます
- また、エラーによる停止やctrl+Cによる停止時にも、withを使っている場合は自動的にロック解除されます
- ただし、ウィンドウごと消した場合など、ロック解除されない場合もあります
-
下記はwithを使わない場合の書き方です
rlock = rename_lock("./demo_file.txt")
print(rlock.filename)
rlock.unlock()
