From 682adbc0cad2baa1a6119013b166f52de3ee3352 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Mon, 15 Nov 2010 20:40:43 +0100 Subject: scan_path(): Improve handling of inaccessible directories When scanning a tree containing inaccessible directories (e.g. '.ssh' directories in users' homedirs, or repos with explicitly restricted access), scan_path() currently causes three lines of "Permissions denied" errors to be printed to the CGI error log per inaccessible directory: Error checking path /home/foo/.ssh: Permission denied (13) Error checking path /home/foo/.ssh/.git: Permission denied (13) Error opening directory /home/foo/.ssh: Permission denied (13) This is a side-effect of calling is_git_dir(path) and is_git_dir(fmt("%s/.git", path) _before_ we try to opendir(path). By placing the opendir(path) before the two is_git_dir() calls, we reduce the noise to a single line per inaccessible directory: Error opening directory /home/foo/.ssh: Permission denied (13) Signed-off-by: Johan Herland Signed-off-by: Lars Hjemli --- scan-tree.c | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) diff --git a/scan-tree.c b/scan-tree.c index a0e09ce..eda8c67 100644 --- a/scan-tree.c +++ b/scan-tree.c @@ -159,24 +159,23 @@ static void add_repo(const char *base, const char *path, repo_config_fn fn) static void scan_path(const char *base, const char *path, repo_config_fn fn) { - DIR *dir; + DIR *dir = opendir(path); struct dirent *ent; char *buf; struct stat st; + if (!dir) { + fprintf(stderr, "Error opening directory %s: %s (%d)\n", + path, strerror(errno), errno); + return; + } if (is_git_dir(path)) { add_repo(base, path, fn); - return; + goto end; } if (is_git_dir(fmt("%s/.git", path))) { add_repo(base, fmt("%s/.git", path), fn); - return; - } - dir = opendir(path); - if (!dir) { - fprintf(stderr, "Error opening directory %s: %s (%d)\n", - path, strerror(errno), errno); - return; + goto end; } while((ent = readdir(dir)) != NULL) { if (ent->d_name[0] == '.') { @@ -202,6 +201,7 @@ static void scan_path(const char *base, const char *path, repo_config_fn fn) scan_path(base, buf, fn); free(buf); } +end: closedir(dir); } -- cgit v1.2.3-2-gb3c3
