This breaks a URL like: .../cgit?p=about which is generated when using the "root-readme" configuration option. This happens because "page" is set to "about" when parsing the query string before we handle the path (which is empty, but non-null). It turns out that this is not the only case which is broken, but specifying repository and page via query options has been broken since before the commit mentioned above, for example: .../cgit?r=git&p=log Fix both of these by allowing the previous state to persist if PATH_INFO is empty, falling back to the query parameters if no path has been requested. Reported-by: Tom Ryder Signed-off-by: John Keeping --- This is still a bit of a mess, but I'm not really sure what we should be doing when both PATH_INFO and query parameters are provided. At least this change fixes the particular case Tom reported and I think it also makes sure that any links we generate will be handled correctly. parsing.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/parsing.c b/parsing.c index b8d7f10..fd1ea99 100644 --- a/parsing.c +++ b/parsing.c @@ -20,11 +20,10 @@ void cgit_parse_url(const char *url) char *c, *cmd, *p; struct cgit_repo *repo; - ctx.repo = NULL; - ctx.qry.page = NULL; if (!url || url[0] == '\0') return; + ctx.qry.page = NULL; ctx.repo = cgit_get_repoinfo(url); if (ctx.repo) { ctx.qry.repo = ctx.repo->url; -- 2.14.1.555.g1b9dbff880.dirty
