[PATCH] file seperator handling for the other 'OS' -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [PATCH] file seperator handling for the other 'OS' From: K Thananchayan <thananck@yahoo.com> The following patch maintains repo root relative source file names in canonical form (with '/' as file seperator). Mercurial calls os.path.join, os.path.normpath, os.path.walk that use platform's file seperator. This patch does not change seperator in these circumstances (except when the result refer to source files). manifest hash: 2fbb4cb0d3d0bc4f4de5c7c8803fb738072ec6c5 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCuNuBywK+sNU5EO8RAhAZAKCV8cz11+rdof9n1tHb0uDScF34GgCeITNi 4aVikToPXqXyReN9kFP5pnY= =xcV5 -----END PGP SIGNATURE-----
