From 730220de8be669257287e9a1f5dde349ace5426a Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Sat, 24 Jul 2010 16:49:04 +0200 Subject: [PATCH] Do not unquote + into ' ' in URLs Since 9d2e942 (decode file:// and ssh:// URLs, 2010-05-23) the URL logic unquotes escaped URLs. For the %2B type of escape, this is conformant with RFC 2396. However, it also unquotes + into a space character, which is only appropriate for the query strings in HTTP. This notably broke fetching from the gtk+ repository. We cannot just remove the corresponding code since the same url_decode_internal() is also used by the HTTP backend to decode query parameters. Introduce a new argument that controls whether the + decoding happens, and use it only in the (client-side) url_decode().
