From bdec6f2b20440b53859e472d185a21f1951341d5 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Mon, 9 Mar 2009 12:21:46 +0000 Subject: - Frank Hempel found out a bug and provided the fix: curl_easy_duphandle did not necessarily duplicate the CURLOPT_COOKIEFILE option. It only enabled the cookie engine in the destination handle if data->cookies is not NULL (where data is the source handle). In case of a newly initialized handle which just had the cookie support enabled by a curl_easy_setopt(handle, CURL_COOKIEFILE, "")-call, handle->cookies was still NULL because the setopt-call only appends the value to data->change.cookielist, hence duplicating this handle would not have the cookie engine switched on. We also concluded that the slist-functionality would be suitable for being put in its own module rather than simply hanging out in lib/sendf.c so I created lib/slist.[ch] for them. --- lib/Makefile.inc | 4 +- lib/easy.c | 15 ++++++ lib/sendf.c | 78 +------------------------------ lib/slist.c | 136 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ lib/slist.h | 33 ++++++++++++++ 5 files changed, 187 insertions(+), 79 deletions(-) create mode 100644 lib/slist.c create mode 100644 lib/slist.h (limited to 'lib') diff --git a/lib/Makefile.inc b/lib/Makefile.inc index 9991fd89c..e4e631d0b 100644 --- a/lib/Makefile.inc +++ b/lib/Makefile.inc @@ -10,7 +10,7 @@ CSOURCES = file.c timeval.c base64.c hostip.c progress.c formdata.c \ hostares.c hostasyn.c hostip4.c hostip6.c hostsyn.c hostthre.c \ inet_ntop.c parsedate.c select.c gtls.c sslgen.c tftp.c splay.c \ strdup.c socks.c ssh.c nss.c qssl.c rawstr.c curl_addrinfo.c \ - socks_gssapi.c socks_sspi.c curl_sspi.c + socks_gssapi.c socks_sspi.c curl_sspi.c slist.c HHEADERS = arpa_telnet.h netrc.h file.h timeval.h qssl.h hostip.h \ progress.h formdata.h cookie.h http.h sendf.h ftp.h url.h dict.h \ @@ -21,4 +21,4 @@ HHEADERS = arpa_telnet.h netrc.h file.h timeval.h qssl.h hostip.h \ strtoofft.h strerror.h inet_ntop.h curlx.h memory.h setup.h \ transfer.h select.h easyif.h multiif.h parsedate.h sslgen.h gtls.h \ tftp.h sockaddr.h splay.h strdup.h setup_once.h socks.h ssh.h nssg.h \ - curl_base64.h rawstr.h curl_addrinfo.h curl_sspi.h + curl_base64.h rawstr.h curl_addrinfo.h curl_sspi.h slist.h diff --git a/lib/easy.c b/lib/easy.c index c0670d519..dc6c59366 100644 --- a/lib/easy.c +++ b/lib/easy.c @@ -84,6 +84,7 @@ #include "sendf.h" /* for failf function prototype */ #include "http_ntlm.h" #include "connect.h" /* for Curl_getconnectinfo */ +#include "slist.h" #define _MPRINTF_REPLACE /* use our functions only */ #include @@ -648,6 +649,16 @@ CURL *curl_easy_duphandle(CURL *incurl) /* duplicate all values in 'change' */ +#if !defined(CURL_DISABLE_HTTP) && !defined(CURL_DISABLE_COOKIES) + if(data->change.cookielist) { + outcurl->change.cookielist = + Curl_slist_duplicate(data->change.cookielist); + + if (!outcurl->change.cookielist) + break; + } +#endif /* CURL_DISABLE_HTTP */ + if(data->change.url) { outcurl->change.url = strdup(data->change.url); if(!outcurl->change.url) @@ -692,6 +703,10 @@ CURL *curl_easy_duphandle(CURL *incurl) Curl_rm_connc(outcurl->state.connc); if(outcurl->state.headerbuff) free(outcurl->state.headerbuff); +#if !defined(CURL_DISABLE_HTTP) && !defined(CURL_DISABLE_COOKIES) + if(outcurl->change.cookielist) + curl_slist_free_all(outcurl->change.cookielist); +#endif if(outcurl->change.url) free(outcurl->change.url); if(outcurl->change.referer) diff --git a/lib/sendf.c b/lib/sendf.c index 5b7a6beb3..e622b9ac6 100644 --- a/lib/sendf.c +++ b/lib/sendf.c @@ -5,7 +5,7 @@ * | (__| |_| | _ <| |___ * \___|\___/|_| \_\_____| * - * Copyright (C) 1998 - 2008, Daniel Stenberg, , et al. + * Copyright (C) 1998 - 2009, Daniel Stenberg, , et al. * * This software is licensed as described in the file COPYING, which * you should have received as part of this distribution.
