From cdb46ef3fa6d2bea95ae45b8b807497982b18fd5 Mon Sep 17 00:00:00 2001 From: Aaron Griffin Date: Sun, 4 Mar 2007 09:08:54 +0000 Subject: * Fixed a whole mess of extra '/' pathing issues when a different root is specified * Use db->path when appropriate * Commented out the FAKEROOT checks in libalpm. This should never ever be done. TODO test this quite a bit, as this will never cause the transactions to fail if RW operations are requested... right now it is totally up to the front end to decide when to fail * Use realpath() to canonicalize the root path when specified, so _alpm_makepath() doesn't freak out * Fixed some output/indent of MDFile and SHAFile algorithms * More efficient sprintf() usage in MDFile/SHAFile * Added real error output to _alpm_makepath --- lib/libalpm/add.c | 2 +- lib/libalpm/alpm.c | 4 ++-- lib/libalpm/be_files.c | 4 ++-- lib/libalpm/db.c | 2 +- lib/libalpm/handle.c | 57 +++++++++++++++++++++++++++++-------------------- lib/libalpm/md5driver.c | 20 ++++------------- lib/libalpm/sha1.c | 53 ++++++++++++++++++++++----------------------- lib/libalpm/sync.c | 11 +++++----- lib/libalpm/util.c | 2 ++ 9 files changed, 78 insertions(+), 77 deletions(-) diff --git a/lib/libalpm/add.c b/lib/libalpm/add.c index a5fc6fb9..97d1ea72 100644 --- a/lib/libalpm/add.c +++ b/lib/libalpm/add.c @@ -816,7 +816,7 @@ int _alpm_add_commit(pmtrans_t *trans, pmdb_t *db) /* run the post-install script if it exists */ if(alpm_pkg_has_scriptlet(newpkg) && !(trans->flags & PM_TRANS_FLAG_NOSCRIPTLET)) { char pm_install[PATH_MAX];
