The protocol block keeps + crlf="headers" because runtests.pl normalizes protocol verification when any + crlf attribute is present. + +(cherry picked from commit c1cfdf59acbaf9504c4578d4cf56cdd7c8594507) +Signed-off-by: Deepak Rathore +--- + lib/setopt.c | 18 ++++- + lib/vauth/vauth.h | 2 + + tests/data/Makefile.inc | 1 + + tests/data/test1588 | 106 ++++++++++++++++++++++++++ + tests/libtest/Makefile.inc | 5 +- + tests/libtest/lib1588.c | 152 +++++++++++++++++++++++++++++++++++++ + tests/runtests.pl | 2 + + 7 files changed, 283 insertions(+), 3 deletions(-) + create mode 100644 tests/data/test1588 + create mode 100644 tests/libtest/lib1588.c + +diff --git a/lib/setopt.c b/lib/setopt.c +index 8a5a5d7..7eaf309 100644 +--- a/lib/setopt.c ++++ b/lib/setopt.c +@@ -51,6 +51,7 @@ + #include "altsvc.h" + #include "hsts.h" + #include "tftp.h" ++#include "vauth/vauth.h" + #include "strdup.h" + /* The last 3 #include files should be in this order */ + #include "curl_printf.h" +@@ -76,6 +77,20 @@ CURLcode Curl_setstropt(char **charp, const char *s) + return CURLE_OK; + } + ++#ifndef CURL_DISABLE_PROXY ++static CURLcode setproxy(struct Curl_easy *data, const char *proxy) ++{ ++ if((data->set.str[STRING_PROXY] && proxy) && ++ /* there was one set, is this a new one? */ ++ !strcmp(data->set.str[STRING_PROXY], proxy)) ++ return CURLE_OK; /* same one as before */ ++ ++ Curl_auth_digest_cleanup(&data->state.proxydigest); ++ memset(&data->state.authproxy, 0, sizeof(data->state.authproxy)); ++ return Curl_setstropt(&data->set.str[STRING_PROXY], proxy); ++} ++#endif ++ + CURLcode Curl_setblobopt(struct curl_blob **blobp, + const struct curl_blob *blob) + { +@@ -1139,8 +1154,7 @@ CURLcode Curl_vsetopt(struct Curl_easy *data, CURLoption option, va_list param) + * Setting it to NULL, means no proxy but allows the environment variables + * to decide for us (if CURLOPT_SOCKS_PROXY setting it to NULL). + */ +- result = Curl_setstropt(&data->set.str[STRING_PROXY], +- va_arg(param, char *)); ++ result = setproxy(data, va_arg(param, char *)); + break; + + case CURLOPT_PRE_PROXY: +diff --git a/lib/vauth/vauth.h b/lib/vauth/vauth.h +index 9da0540..bf5c7a3 100644 +--- a/lib/vauth/vauth.h ++++ b/lib/vauth/vauth.h +@@ -119,6 +119,8 @@ CURLcode Curl_auth_create_digest_http_message(struct Curl_easy *data, + + /* This is used to clean up the digest specific data */ + void Curl_auth_digest_cleanup(struct digestdata *digest); ++#else ++#define Curl_auth_digest_cleanup(x) + #endif /* !CURL_DISABLE_DIGEST_AUTH */ + + #ifdef USE_GSASL +diff --git a/tests/data/Makefile.inc b/tests/data/Makefile.inc +index f673f86..461eb37 100644 +--- a/tests/data/Makefile.inc ++++ b/tests/data/Makefile.inc +@@ -200,6 +200,7 @@ test1540 test1541 test1542 test1543 test1544 test1545 \ + test1550 test1551 test1552 test1553 test1554 test1555 test1556 test1557 \ + test1558 test1559 test1560 test1561 test1562 test1563 test1564 test1565 \ + test1566 test1567 test1568 test1569 test1570 \ ++test1588 \ + \ + test1590 test1591 test1592 test1593 test1594 test1595 test1596 test1597 \ + test1598 \ +diff --git a/tests/data/test1588 b/tests/data/test1588 +new file mode 100644 +index 0000000..8a3bf81 +--- /dev/null ++++ b/tests/data/test1588 +@@ -0,0 +1,106 @@ ++ ++ ++ ++ ++HTTP ++HTTP GET ++HTTP proxy ++HTTP proxy Digest auth ++multi ++ ++ ++ ++# Server-side ++ ++ ++# this is returned first since we get no proxy-auth ++ ++HTTP/1.1 407 Authorization Required to proxy me my dear ++Proxy-Authenticate: Digest realm="weirdorealm", nonce="12345" ++Content-Length: 33 ++ ++And you should ignore this data. ++ ++ ++# then this is returned when we get proxy-auth ++ ++HTTP/1.1 200 OK ++Content-Length: 21 ++Server: no ++ ++Nice proxy auth sir!
