The code is a persistent source of vulnerabilities and +fixing it requires significant effort. We should not be spending scarce +Project resources on improving that code, especially given the lack of +strong demand for Gopher support. + +With this change, Gopher requests will be handled like any other request +with an unknown (to Squid) protocol. For example, HTTP requests with +Gopher URI scheme result in ERR_UNSUP_REQ. + +Default Squid configuration still considers TCP port 70 "safe". The +corresponding Safe_ports ACL rule has not been removed for consistency +sake: We consider WAIS port safe even though Squid refuses to forward +WAIS requests: + + acl Safe_ports port 70 # gopher + acl Safe_ports port 210 # wais + +Conflict:Context adaptation + errors/*.po=>errors/*/ERR_UNSUP_REQ + src/error/forward.h => src/err_type.h + src/http/Message.h => src/HttpMsg.h +Reference:https://github.com/squid-cache/squid/commit/6ea12e8fb590ac6959e9356a81aa3370576568c3 +--- + doc/debug-sections.txt | 1 - + errors/af/ERR_UNSUP_REQ | 2 +- + errors/ar/ERR_UNSUP_REQ | 2 +- + errors/az/ERR_UNSUP_REQ | 2 +- + errors/bg/ERR_UNSUP_REQ | 2 +- + errors/ca/ERR_UNSUP_REQ | 2 +- + errors/cs/ERR_UNSUP_REQ | 2 +- + errors/da/ERR_UNSUP_REQ | 2 +- + errors/de/ERR_UNSUP_REQ | 2 +- + errors/el/ERR_UNSUP_REQ | 2 +- + errors/en/ERR_UNSUP_REQ | 2 +- + errors/errorpage.css | 2 +- + errors/es/ERR_UNSUP_REQ | 2 +- + errors/et/ERR_UNSUP_REQ | 2 +- + errors/fa/ERR_UNSUP_REQ | 2 +- + errors/fi/ERR_UNSUP_REQ | 2 +- + errors/fr/ERR_UNSUP_REQ | 2 +- + errors/he/ERR_UNSUP_REQ | 2 +- + errors/hu/ERR_UNSUP_REQ | 2 +- + errors/hy/ERR_UNSUP_REQ | 2 +- + errors/id/ERR_UNSUP_REQ | 2 +- + errors/it/ERR_UNSUP_REQ | 2 +- + errors/ja/ERR_UNSUP_REQ | 2 +- + errors/ka/ERR_UNSUP_REQ | 2 +- + errors/ko/ERR_UNSUP_REQ | 2 +- + errors/lt/ERR_UNSUP_REQ | 2 +- + errors/lv/ERR_UNSUP_REQ | 2 +- + errors/ms/ERR_UNSUP_REQ | 2 +- + errors/nl/ERR_UNSUP_REQ | 2 +- + errors/oc/ERR_UNSUP_REQ | 2 +- + errors/pl/ERR_UNSUP_REQ | 2 +- + errors/pt-br/ERR_UNSUP_REQ | 2 +- + errors/pt/ERR_UNSUP_REQ | 2 +- + errors/ro/ERR_UNSUP_REQ | 2 +- + errors/ru/ERR_UNSUP_REQ | 2 +- + errors/sk/ERR_UNSUP_REQ | 2 +- + errors/sl/ERR_UNSUP_REQ | 2 +- + errors/sr-cyrl/ERR_UNSUP_REQ | 2 +- + errors/sr-latn/ERR_UNSUP_REQ | 2 +- + errors/sv/ERR_UNSUP_REQ | 2 +- + errors/templates/ERR_UNSUP_REQ | 2 +- + errors/th/ERR_UNSUP_REQ | 2 +- + errors/tr/ERR_UNSUP_REQ | 2 +- + errors/uk/ERR_UNSUP_REQ | 2 +- + errors/uz/ERR_UNSUP_REQ | 2 +- + errors/vi/ERR_UNSUP_REQ | 2 +- + errors/zh-hans/ERR_UNSUP_REQ | 2 +- + errors/zh-hant/ERR_UNSUP_REQ | 2 +- + src/FwdState.cc | 5 - + src/HttpMsg.h | 1 - + src/HttpRequest.cc | 6 - + src/IoStats.h | 2 +- + src/Makefile.am | 14 - + src/adaptation/ecap/Host.cc | 1 - + src/adaptation/ecap/MessageRep.cc | 2 - + src/anyp/ProtocolType.cc | 1 - + src/anyp/ProtocolType.h | 1 - + src/anyp/Uri.cc | 2 - + src/anyp/UriScheme.cc | 3 - + src/cf.data.pre | 5 +- + src/client_side_request.cc | 4 - + src/err_type.h | 2 +- + src/gopher.cc | 967 ----------------------- + src/gopher.h | 29 - + src/mgr/IoAction.cc | 3 - + src/mgr/IoAction.h | 2 - + src/squid.8.in | 2 +- + src/stat.cc | 19 - + test-suite/squidconf/regressions-3.4.0.1 | 1 - + 69 files changed, 52 insertions(+), 1115 deletions(-) + delete mode 100644 src/gopher.cc + delete mode 100644 src/gopher.h + +diff --git a/doc/debug-sections.txt b/doc/debug-sections.txt +index 7820bfd..dc3c1fb 100644 +--- a/doc/debug-sections.txt ++++ b/doc/debug-sections.txt +@@ -27,7 +27,6 @@ section 06 Disk I/O Routines + section 07 Multicast + section 08 Swap File Bitmap + section 09 File Transfer Protocol (FTP) +-section 10 Gopher + section 11 Hypertext Transfer Protocol (HTTP) + section 12 Internet Cache Protocol (ICP) + section 13 High Level Memory Pool Management +diff --git a/errors/af/ERR_UNSUP_REQ b/errors/af/ERR_UNSUP_REQ +index fceed19..338e1c6 100644 +--- a/errors/af/ERR_UNSUP_REQ ++++ b/errors/af/ERR_UNSUP_REQ +@@ -24,7 +24,7 @@ body +
