This seems to require OpenSSL_config() or + CONF_modules_load_file() to be used by libcurl but the first seems to not + work and we've gotten not reports from tests with the latter. Possibly we + need to discuss with OpenSSL developers how this is supposed to be done.

When building with the Windows Borland compiler, it fails because the "tlib" tool doesn't support hyphens (minus signs) in file names and we have such in the build. diff --git a/lib/easy.c b/lib/easy.c index 94a84abb2..32a887657 100644 --- a/lib/easy.c +++ b/lib/easy.c @@ -50,6 +50,11 @@ #include <sys/param.h> #endif +#if defined(HAVE_SIGNAL_H) && defined(HAVE_SIGACTION) && defined(USE_OPENSSL) +#define SIGPIPE_IGNORE 1 +#include <signal.h> +#endif + #include "strequal.h" #include "urldata.h" #include <curl/curl.h> @@ -81,6 +86,49 @@ /* The last #include file should be: */ #include "memdebug.h" +#ifdef SIGPIPE_IGNORE +#define SIGPIPE_VARIABLE(x) struct sigaction x + +/* + * sigpipe_ignore() makes sure we ignore SIGPIPE while running libcurl + * internals, and then sigpipe_restore() will restore the situation when we + * return from libcurl again. + */ +static void sigpipe_ignore(struct SessionHandle *data, + struct sigaction *pipe) +{ + if(!data->set.no_signal) { + struct sigaction action; + /* first, extract the existing situation */ + sigaction(SIGPIPE, NULL, pipe); + action = *pipe; + /* ignore this signal */ + action.sa_handler = SIG_IGN; + sigaction(SIGPIPE, &action, NULL); + } +} + +/* + * sigpipe_restore() puts back the outside world's opinion of signal handler + * and SIGPIPE handling.
