Section: 18.104.22.168 [fs.op.weakly.canonical] Status: C++20 Submitter: Jonathan Wakely Opened: 2017-10-14 Last modified: 2021-06-06
View all issues with C++20 status.
LWG 2956 fixed canonical to no longer use a base path, but weakly_canonical should have been changed too:
Effects: Using status(p) or status(p, ec), respectively, to determine existence, return a path composed by operator/= from the result of calling canonical() without a base argument and with a […]
Since canonical doesn't accept a base argument, it doesn't make sense to talk about calling it without one.
[ 2017-10-16 Moved to Tentatively Ready after 5 positive votes on c++std-lib. ]
[2018-3-17 Adopted in Jacksonville]
This wording is relative to N4687.
Change [fs.op.weakly_canonical] as indicated:
path weakly_canonical(const path& p); path weakly_canonical(const path& p, error_code& ec);
-1- Returns: […]-2- Effects: Using status(p) or status(p, ec), respectively, to determine existence, return a path composed by operator/= from the result of calling canonical()
without a base argument andwith a path argument composed of the leading elements of p that exist, if any, followed by the elements of p that do not exist, if any. For the first form, canonical() is called without an error_code argument. For the second form, canonical() is called with ec as an error_code argument, and path() is returned at the first error occurrence, if any. […]
