                                  Changelog

Daniel Stenberg (10 Dec 2009)

- Siegfried Gyuricsko found out that the curl manual said --retry would retry

  on FTP errors in the transient 5xx range. Transient FTP errors are in the

  4xx range. The code itself only tried on 5xx errors that occured _at login_.

  Now the retry code retries on all FTP transfer failures that ended with a

  4xx response.

  (http://curl.haxx.se/bug/view.cgi?id=2911279)

- Constantine Sapuntzakis figured out a case which would lead to libcurl

  accessing alredy freed memory and thus crash when using HTTPS (with

  OpenSSL), multi interface and the CURLOPT_DEBUGFUNCTION and a certain order

 o TFTP BLKSIZE

 o Expect: 100-continue handling when set by the application

 o multi interface with OpenSSL read already freed memory when closing down

 o --retry didn't do right for FTP transient errors

This release includes the following known bugs:

 Yang Tse, Kamil Dudka, Christian Schmitz, Constantine Sapuntzakis,

 Marco Maggi, Camille Moncelier, Claes Jakobsson, Kevin Baughman,

 Marc Kleine-Budde, Jad Chamcham, Bjorn Augustsson, David Byron,

        Thanks! (and sorry if I forgot to mention someone)

If a transient error is returned when curl tries to perform a transfer, it

will retry this number of times before giving up. Setting the number to 0

makes curl do no retries (which is the default). Transient error means either:

a timeout, an FTP 5xx response code or an HTTP 5xx response code.

a timeout, an FTP 4xx response code or an HTTP 5xx response code.

When curl is about to retry a transfer, it will first wait one second and then

for all forthcoming retries it will double the waiting time until it reaches

                }

              }

            } /* if CURLE_OK */

            else if(CURLE_LOGIN_DENIED == res) {

            else if(res) {

              curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &response);

              if(response/100 == 5)

              if(response/100 == 4)
