Subject: timeout handling: auto-detect effective timeout
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8ce16e7bf29925eb89b602861623695efc7a4af6;p=thirdparty%2Fcurl.git

timeout handling: auto-detect effective timeout

When checking a transfer for being expired via `Curl_timeleft_ms()`,
eleminate the `bool connecting` parameter and have the function check
the `mstate` of the transfer instead.

Advantages:
* eleminate the caller needing awareness if the transfer is
  connecting or in a later state
* fix pingpong timeout handling to check the correct timeout
  during "proto_connect" phases
* avoid using "connecting" timeouts during establishing a secondary
  connection (e.g. FTP) since this would use the timestamp from
  the original, primary connect and thus be wrong

Reported-by: Wyuer on github
Fixes #20347
Closes #20354
