From: Zachary T Welch Date: Thu, 3 Dec 2009 13:13:45 +0000 (-0800) Subject: fix regressions with GDB port numbers X-Git-Tag: v0.4.0-rc1~145 X-Git-Url: https://review.openocd.org/gitweb?p=openocd.git;a=commitdiff_plain;h=23f07d08e3998642326aa115cdd4cb1199f2704b;hp=434f570e51a0b0f2c09184646d91154c74bbff81 fix regressions with GDB port numbers Use a separate variable for iterating GDB service port numbers than the one set by the user. Restores the behavior of returning the original port number and only incrementing the port used on success. --- diff --git a/src/server/gdb_server.c b/src/server/gdb_server.c index 40380a8993..21cd0fed9f 100644 --- a/src/server/gdb_server.c +++ b/src/server/gdb_server.c @@ -48,6 +48,7 @@ static enum breakpoint_type gdb_breakpoint_override_type; extern int gdb_error(struct connection *connection, int retval); static unsigned short gdb_port = 3333; +static unsigned short gdb_port_next = 0; static const char *DIGITS = "0123456789abcdef"; static void gdb_log_callback(void *priv, const char *file, unsigned line, @@ -2217,6 +2218,8 @@ int gdb_target_add_one(struct target *target) LOG_INFO("gdb port disabled"); return ERROR_OK; } + if (0 == gdb_port_next) + gdb_port_next = gdb_port; bool use_pipes = server_use_pipes; static bool server_started_with_pipes = false; @@ -2229,10 +2232,12 @@ int gdb_target_add_one(struct target *target) use_pipes = false; } - int e = gdb_target_start(target, use_pipes ? 0 : gdb_port++); + int e = gdb_target_start(target, use_pipes ? 0 : gdb_port_next); if (ERROR_OK == e) + { server_started_with_pipes |= use_pipes; - + gdb_port_next++; + } return e; } @@ -2278,7 +2283,10 @@ COMMAND_HANDLER(handle_gdb_sync_command) /* daemon configuration command gdb_port */ COMMAND_HANDLER(handle_gdb_port_command) { - return CALL_COMMAND_HANDLER(server_port_command, &gdb_port); + int retval = CALL_COMMAND_HANDLER(server_port_command, &gdb_port); + if (ERROR_OK == retval) + gdb_port_next = gdb_port; + return retval; } COMMAND_HANDLER(handle_gdb_memory_map_command)
