See https://github.com/curl/curl/issues/1332 and https://github.com/curl/curl/issues/4296 -11.7 signal-based resolver timeouts - - libcurl built without an asynchronous resolver library uses alarm() to time - out DNS lookups. When a timeout occurs, this causes libcurl to jump from the - signal handler back into the library with a sigsetjmp, which effectively - causes libcurl to continue running within the signal handler. This is - non-portable and could cause problems on some platforms. A discussion on the - problem is available at https://curl.se/mail/lib-2008-09/0197.html - - Also, alarm() provides timeout resolution only to the nearest second. alarm - ought to be replaced by setitimer on systems that support it. - -11.16 libcurl uses renames instead of locking for atomic operations - - For saving cookies, alt-svc and hsts files.
