net/http: improve signature of Redirect, NewRequest
In CL https://golang.org/cl/
4893043 (6 years ago), a new package named
"url" was created (it is currently known as "net/url"). During that
change, some identifier name collisions were introduced, and two
parameters in net/http were renamed to "urlStr".
Since that time, Go has continued to put high emphasis on the quality
and readability of the documentation. Sometimes, that means making small
sacrifices in the implementation details of a package to ensure that
the godoc reads better, since that's what the majority of users interact
with. See https://golang.org/s/style#named-result-parameters:
> Clarity of docs is always more important than saving a line or two
> in your function.
I think the "urlStr" parameter name is suboptimal for godoc purposes,
and just "url" would be better.
During the review of https://golang.org/cl/
4893043, it was also noted
by @rsc that having to rename parameters named "url" was suboptimal:
> It's unfortunate that naming the package url means
> you can't have a parameter or variable named url.
However, at the time, the name of the url package was still being
decided, and uri was an alternative name under consideration.
The reason urlStr was chosen is because it was a lesser evil
compared to naming the url package uri instead:
> Let's not get hung up on URI vs. URL, but I'd like s/uri/urlStr/ even for just
> that the "i" in "uri" looks very similar to the "l" in "url" in many fonts.
> Please let's go with urlStr instead of uri.
Now that we have the Go 1 compatibility guarantee, the name of the
net/url package is fixed. However, it's possible to improve the
signature of Redirect, NewRequest functions in net/http package
for godoc purposes by creating a package global alias to url.Parse,
and renaming urlStr parameter to url in the exported funcs. This CL
does so.
Updates #21077.
