From 472e51b975b9cb8fe1f67c03ff72bbc067fa7f01 Mon Sep 17 00:00:00 2001 From: Nagy Gabor Date: Sun, 18 Jan 2009 20:03:56 +0100 Subject: [PATCH] Use archive_entry_set_perm instead of archive_entry_set_mode This patch fixes FS#12148 ('unstable' regular file). I also changed the other archive_entry_set_mode usage in add.c to archive_entry_set_perm. Since I cannot find any relevant info in libarchive manual, I quote Tim Kientzle (the author of libarchive) here, and I say thank you for his help. *** Tim Kientzle wrote ************************************* This is the problem in libalpm/util.c: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_mode(entry, 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_mode(entry, 0755); 327 } Your example unstable.db.tar.gz is not empty. It has one entry in it, called "./". That entry is marked as a directory. But, when you call archive_entry_set_mode(), you are changing the file type! archive_read_extract() then creates the file /var/unstable as you requested. (archive_read_extract() will replace an empty directory with a file.) You should either set the mode value correctly: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_mode(entry, IFREG | 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_mode(entry, IFDIR | 0755); 327 } Or use archive_entry_set_perm(), which does not change the file type: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_perm(entry, 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_perm(entry, 0755); 327 } ************************************************************ Signed-off-by: Nagy Gabor Signed-off-by: Dan McGee --- lib/libalpm/add.c | 4 ++-- lib/libalpm/util.c | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/lib/libalpm/add.c b/lib/libalpm/add.c index 1e8ec9f2..838f5a6d 100644 --- a/lib/libalpm/add.c +++ b/lib/libalpm/add.c @@ -292,12 +292,12 @@ static int extract_single_file(struct archive *archive, /* the install script goes inside the db */ snprintf(filename, PATH_MAX, "%s%s-%s/install", db->path, newpkg->name, newpkg->version); - archive_entry_set_mode(entry, 0644); + archive_entry_set_perm(entry, 0644); } else if(strcmp(entryname, ".CHANGELOG") == 0) { /* the changelog goes inside the db */ snprintf(filename, PATH_MAX, "%s%s-%s/changelog", db->path, newpkg->name, newpkg->version); - archive_entry_set_mode(entry, 0644); + archive_entry_set_perm(entry, 0644); } else if(*entryname == '.') { /* for now, ignore all files starting with '.' that haven't * already been handled (for future possibilities) */ diff --git a/lib/libalpm/util.c b/lib/libalpm/util.c index da3463b0..be465afa 100644 --- a/lib/libalpm/util.c +++ b/lib/libalpm/util.c @@ -310,9 +310,9 @@ int _alpm_unpack(const char *archive, const char *prefix, const char *fn) entryname = archive_entry_pathname(entry); if(S_ISREG(st->st_mode)) { - archive_entry_set_mode(entry, 0644); + archive_entry_set_perm(entry, 0644); } else if(S_ISDIR(st->st_mode)) { - archive_entry_set_mode(entry, 0755); + archive_entry_set_perm(entry, 0755); } /* If a specific file was requested skip entries that don't match. */
