I'm similarly confused by this issue. If somebody can help me understand what's
going on, I'll put my understanding into a documentation patch.
I have created this minimal example to demonstrate what I don't understand:
I've created a directory structure within /tmp like this:
issue22021
└── root
└── structure
├── content
│ └── please_add.txt
└── do_not_add.txt
Now I'd like to create a zip archive that contains the directories "structure"
and "content", and the file "please_add.txt", but not the file
"do_not_add.txt". My understanding of the documentation was that I'd have to do
this:
>>> shutil.make_archive(base_name='/tmp/issue22021archive', format='zip',
>>> root_dir='/tmp/issue22021/root',
>>> base_dir='/tmp/issue22021/root/structure/content')
But on my system, the created file (/tmp/issue22021archive.zip) looks like this
according to unzip -l:
Archive: issue22021archive.zip
Length Date Time Name
--------- ---------- ----- ----
0 2018-05-30 00:26 tmp/issue22021/root/structure/content/
0 2018-05-30 00:26
tmp/issue22021/root/structure/content/please_add.txt
--------- -------
0 2 files
This is consistent with my experience that created archives will always contain
directories from / on, which is unexpected to me.
It appears this happens whenever base_dir and root_dir is set, but to my
understanding the documentation does not warn against this.
I've confirmed this behaviour with Python 3.6.5 and Python 3.5.3, but I suspect
that doesn't really matter, as it seems to be a documentation issue.
