I noticed once I set up a mirror of my own, that Cygwin Setup will prepend all it's URL's with a double-slash. This does not seem to be intentional, and I found the place in the sources where I believe the error to be.
On line 160 of "download.cc", we see that the "n->key" is the source of the repository, including a "/", as it is used as the name of the local cache, which always has a "%2f" in its name. That key is then used on line 165 in "get_url_to_file", where it is concatenated with another slash and "pkgsource.Canonical" to make the final URL. My (untested) patch removes this slash, so that the resulting URL's will be with a single slash. ------ PATCH ----- diff --git a/download.cc b/download.cc index a5aebe0..e319ed4 100644 --- a/download.cc +++ b/download.cc @@ -162,7 +162,7 @@ download_one (packagesource & pkgsource, HWND owner) pkgsource.Canonical (); io_stream::mkpath_p (PATH_TO_FILE, "file://" + local, 0); - if (get_url_to_file(n->key + "/" + pkgsource.Canonical (), + if (get_url_to_file(n->key + pkgsource.Canonical (), local + ".tmp", pkgsource.size, owner)) { /* FIXME: note new source ? */ ------ PATCH ----- Regards.
