python - 我应该在哪里写入用户特定的日志文件(并且与 XDG 基目录兼容)

Question

默认情况下，pip 将错误记录到“~/.pip/pip.log”。 Pip 有一个更改日志路径的选项，我想将日志文件放在 ~/.pip 之外的某个地方，以免弄乱我的主目录。我应该把它放在哪里XDG base dir compatible ？

现在我正在考虑其中之一:

• $XDG_DATA_HOME(通常是 $HOME/.local/share)
• $XDG_CACHE_HOME(通常是 $HOME/.cache)

Answer 1

目前还不清楚。

不同的软件似乎以不同的方式处理这个问题(imsettings 把它放在 $XDG_CACHE_HOME 中， profanity在 $XDG_DATA_HOME 中)。

Debian , 但是，有一个我可以支持的建议(强调我的):

This is a recurring request/complaint (see this or this) on the xdg-freedesktop mailing list to introduce another directory for state information that does not belong in any of the existing categories (see also home-dir.proposal. Examples for this information are:

• history files of shells, repls, anything that uses libreadline
• logfiles
• state of application windows on exit
• recently opened files
• last time application was run
• emacs: bookmarks, ido last directories, backups, auto-save files, auto-save-list

The above example information is not essential data. However it should still persist on reboots of the system unlike cache data that a user might consider putting in a TMPFS. On the other hand the data is rather volatile and does not make sense to be checked into a VCS. The files are also not the data files that an application works on.

A default folder for a future STATE category might be: $HOME/.local/state

这将有效地引入另一个环境变量，因为 $XDG_DATA_HOME 通常指向 $HOME/.local/share 并且这个假设的环境变量 ( $XDG_STATE_HOME?) 将指向 $HOME/.local/state

如果您真的想遵守当前标准，我会将我的日志文件放在 $XDG_CACHE_HOME 中，因为运行程序不需要日志文件。
