Hello,
In a previous mail here [1], I counted strlens done by curl. This then
triggered some work, mostly by Henrik Holst, to update code to not use
strlen() unnecessarily when it can avoid it.
I did a quick follow-up count today. I don't recall the exact build options I
used the last time, so I rebuilt 7.81.0 and current git master with the same
set now and ran a comparison:
ltrace ./src/curl -Ls https://google.com/ -o /dev/null 2>&1 | grep strlen
In 7.81.0 this made 596 to 600 strlen() calls.
In git master, this now makes 390 to 392 calls. A 33% reduction.
(This used OpenSSL/1.1.1m and google.com speaks HTTP/2 and as said before,
makes a redirect)
