Long delay when FTP connection is interrupted from CURLOPT_HEADERFUNCTION callback
Last modified: 2013-09-22 20:07:22 EDT
Created attachment 795521 [details] Reproducer (Use flags "-I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -lglib-2.0 -lcurl") Description of problem: I am using CURLOPT_HEADERFUNCTION for parsing FTP return codes (messages) while downloading via FTP. I am specially interested in FTP code 213 which returns size of a downloaded file. Sometimes I know expected size and when this size differ from size that server reports (via the 213 code), then I want to interrupt this download. The download interruption is done by returning a bad return value from the CURLOPT_HEADERFUNCTION callback. But I've met the problem, that after a bad return value is returned, the CURL hangs for about 60sec (just my estimation, I didn't do exact measurement) before it returns from curl_easy_perform(). My expectation is that curl_easy_perform() return immediately after CURLOPT_HEADERFUNCTION returns the bad return value. Version-Release number of selected component (if applicable): curl-7.29.0-9.fc19.x86_64 libcurl-devel-7.29.0-9.fc19.x86_64 How reproducible: Check the attached reproducer Actual results: 60sec hang after download is interrupted Expected results: no hang

It works! Thank you! Do you plan to make a build with this patch for F18 and F19 sometimes, or it will be only rawhide stuff?
fixed in curl-7.32.0-2.fc21
