Subject: tests: await portfile to be complete
X-Git-Tag: curl-8_14_1~30
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=759d33a25c33820c607f389718e2c212c0f653a1;p=thirdparty%2Fcurl.git

tests: await portfile to be complete

When running under load, a started server may not produce a valid portfile
before the runner starts reading it. If the read is not successful, wait
for 100ms and try again, timing out after 15 seconds.

Fixes #17492
Closes #17495
