Hello,
I am currently facing some issues while trying to write the test for
daemon.c, I need some help on it.
The start_git_daemon function inside lib-git-daemon.sh is made to
allow --init-timeout, --max-connections and
timeout as well as other arguments. The start_git_daemon function in
lib-git-daemon.sh is used at t5570-git-daemon.sh.
Basically this is my changes
                if (skip_prefix(arg, "--timeout=", &v)) {
-                       timeout = atoi(v);
+                       if (strtoul_ui(v, 10, &timeout))
+                               die("invalid timeout '%s', expecting a
non-negative integer", v);
                        continue;
                }
                if (skip_prefix(arg, "--init-timeout=", &v)) {
-                       init_timeout = atoi(v);
+                       if (strtoul_ui(v, 10, &init_timeout))
+                               die("invalid init-timeout '%s',
expecting a non-negative integer", v);
                        continue;
                }
                if (skip_prefix(arg, "--max-connections=", &v)) {
-                       max_connections = atoi(v);
+                       if (strtol_i(v, 10, &max_connections))
+                               die("invalid '--max-connections' '%s',
expecting an integer", v);
                        if (max_connections < 0)
-                               max_connections = 0;            /* unlimited */
+                               max_connections = 0;  /* unlimited */
                        continue;
                }
What happened is that the start_git_daemon will already fail and will
prevent the
t5570-git-daemon.sh from starting if there is any wrong starting
condition such as the new
changes I added. I am finding it hard to come up with an approach to
test the new change.


Thank you.
