Python在另一个进程写入时旋转日志文件

我有以下python脚本，每1秒将输出写入日志文件，如下所示：

python myprocess.py >> mylog.csv

def rotate_logs():
# Rotate all logs from *.csv to *.csv.1
for subdir, dirs, files in os.walk(LOG_FILE_DIRECTORY):
    for filename in files:
        file_ext = os.path.splitext(filename)[1]
        if file_ext == '.1':
            logger.info("Delete %s", os.path.join(subdir, filename))
            os.remove(os.path.join(subdir, filename))
            continue
        if file_ext == '.csv':
            filePath = os.path.join(subdir, filename)  # get the path to your file
            newFilePath = filePath.replace(".csv", ".csv.1"  # create the new name
            logger.info("Changing name from %s to %s", filePath, newFilePath)
            os.rename(filePath, newFilePath) 

我有另一个python脚本

logrotate.py

，每30秒取一次

mylog.csv

文件，将名称更改为

mylog.csv.1

，并将其移动到另一个目录，如下所示：

python myprocess.py >> mylog.csv

def rotate_logs():
# Rotate all logs from *.csv to *.csv.1
for subdir, dirs, files in os.walk(LOG_FILE_DIRECTORY):
    for filename in files:
        file_ext = os.path.splitext(filename)[1]
        if file_ext == '.1':
            logger.info("Delete %s", os.path.join(subdir, filename))
            os.remove(os.path.join(subdir, filename))
            continue
        if file_ext == '.csv':
            filePath = os.path.join(subdir, filename)  # get the path to your file
            newFilePath = filePath.replace(".csv", ".csv.1"  # create the new name
            logger.info("Changing name from %s to %s", filePath, newFilePath)
            os.rename(filePath, newFilePath)

在

logrotate.py

旋转日志文件的同时，我可能会错过

myprocess.py

写入日志的情况下的日志？如果是这样，我该如何防止这种情况发生？

你为什么要重新发明轮子？使用
