2014-03-03qapi: Clean up null checking in generated visitorsMarkus Armbruster1-7/+7
Visitors get passed a pointer to the visited object. The generated visitors try to cope with this pointer being null in some places, for instance like this: visit_start_optional(m, obj ? &(*obj)->has_name : NULL, "name", &err); visit_start_optional() passes its second argument to Visitor method start_optional. Three out of three methods dereference it unconditionally. I fail to see how this pointer could legitimately be null. All this useless null checking is highly redundant, which Coverity duly reports. About 200 times. Remove the useless null checks.

2014-03-03qjson.h: Remove spurious GCC_FMT_ATTR markup from qobject_from_json() ↵Peter Maydell1-1/+1
declaration The function qobject_from_json() doesn't actually allow its argument to be a format string -- it passes a NULL va_list* to qobject_from_jsonv(), and the parser code will then never actually interpret %-escape sequences (it tests whether the va_list pointer is NULL and will stop with a parse error). The spurious attribute markup causes clang warnings in some of the test cases where we programmatically construct JSON to feed to qobject_from_json(): tests/test-qmp-input-visitor.c:76:35: warning: format string is not a string literal (potentially insecure) [-Wformat-security] data->obj = qobject_from_json(json_string); ^~~~~~~~~~~ Remove the incorrect attribute.

2014-02-28block: gluster - add reopen support.Jeff Cody1-0/+102
Gluster does parse open flags in its .bdrv_open() implementation, and the .bdrv_reopen_* implementations need to do the same. A new gluster connection to the image file to be created is established in the .bdrv_reopen_prepare(), and the image file opened with the new flags. If this is successful, then the old image file is closed, and the old connection torn down. The relevant structure pointers in the gluster state structure are updated to the new connection. If it is not successful, then the new file handle and connection is abandoned (if it exists), while the old connection is not modified at all. With reopen supported, block-commit (and offline commit) is now also supported for image files whose base image uses the native gluster protocol driver.
