From d48a72f337fa8edfb7a09e620e75cbbb2a5fe836 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 14 Jul 2005 09:58:45 -0700 Subject: [PATCH] Fix replacing of a directory with a file/symlink in git-checkout-cache The symlink case had never worked, and the file case was broken by the O_EXCL change because the error return changed from EISDIR to EEXIST. Fix both problems by just moving the test for an existing directory to a more logical place. --- entry.c | 20 ++++++++------------ 1 file changed, 8 insertions(+), 12 deletions(-) diff --git a/entry.c b/entry.c index 792ea733e8..15b8fda0c6 100644 --- a/entry.c +++ b/entry.c @@ -57,19 +57,10 @@ static void remove_subtree(const char *path) die("cannot rmdir %s", path); } -static int create_file(const char *path, unsigned int mode, int force) +static int create_file(const char *path, unsigned int mode) { - int fd; - mode = (mode & 0100) ? 0777 : 0666; - fd = open(path, O_WRONLY | O_TRUNC | O_CREAT | O_EXCL, mode); - if (fd < 0) { - if (errno == EISDIR && force) { - remove_subtree(path); - fd = open(path, O_WRONLY | O_TRUNC | O_CREAT | O_EXCL, mode); - } - } - return fd; + return open(path, O_WRONLY | O_TRUNC | O_CREAT | O_EXCL, mode); } static int write_entry(struct cache_entry *ce, const char *path, struct checkout *state) @@ -90,7 +81,7 @@ static int write_entry(struct cache_entry *ce, const char *path, struct checkout } switch (ntohl(ce->ce_mode) & S_IFMT) { case S_IFREG: - fd = create_file(path, ntohl(ce->ce_mode), state->force); + fd = create_file(path, ntohl(ce->ce_mode)); if (fd < 0) { free(new); return error("git-checkout-cache: unable to create file %s (%s)", @@ -151,6 +142,11 @@ int checkout_entry(struct cache_entry *ce, struct checkout *state) * just do the right thing) */ unlink(path); + if (S_ISDIR(st.st_mode)) { + if (!state->force) + return error("%s is a directory", path); + remove_subtree(path); + } } else if (state->not_new) return 0; create_directories(path, state); -- 2.11.4.GIT
