[issue29657] os.symlink: FileExistsError shows wrong message

Yonatan Goldschmidt added the comment: Just reached this issue independently (spent a few minutes debugging an error message like "FileExistsError: [Errno 17] File exists: 'a' -> 'b'", where 'a' didn't exist...) I agree with Rich on this - for me, the source of confusion was that the way Py

Rich Jones added the comment: @Larry - that would be an acceptable solution! I'm here because I encountered this error independently. I explain why the arrow is a problem here: https://bugs.python.org/issue35367 The issue is that the '->' notation is already used by the standard operating

Larry Hastings added the comment: "Special cases aren't special enough to break the rules." I want the error message to mirror the API, which it currently does. If we swapped them, the error message would now contradict the API. So no, I don't support swapping "src" and "dst" in the error m

Xiang Zhang added the comment: I agree with Eryk. The error message is misleading. When I see it, I take it as source -> destination. I think we should make the error message clearer, or document it in the OSError documentation. -- ___ Python tracke

[issue29657] os.symlink: FileExistsError shows wrong message

Eryk Sun added the comment: To me the error message is in the model of a source -> destination operation, in which the arrow indicates the operation's information flow (e.g. of the target path or inode number) from the source file to the destination file. I've never viewed it superficially as

Serhiy Storchaka added the comment: This is not about how a symbolic link is represented. This is about how the operation of creating a symbolic link is represented. The first filename is the first argument of os.symlink(), the second filename is the second argument. Try to run os.symlink

[issue29657] os.symlink: FileExistsError shows wrong message

Eryk Sun added the comment: A symbolic link is typically represented the other way around, from the point of view of the link pointing at the target. However, Python conceptualizes linking as something like a copy or rename operation, with source and destination filenames, and the current erro

Andrew Nester added the comment: I've been investigating this issue and did not come up with some easy solution. So the problem is: os_symlink uses `path_error2` to throw exception. the order of file arguments now is src then dest. For provided example src is `a` and dest is `sym_link`. As a re

Xiang Zhang added the comment: I concur the current message is misleading. OSError makes the string "file1 -> file2". This also affects other methods calling `path_error2()` such as os.link(). -- nosy: +xiang.zhang versions: +Python 3.6, Python 3.7
