Subject: [PATCH] * src/dstring.c (ds_init): Take a single argument.
|
|
|
|
|
(ds_free): New function. (ds_resize): Take a single argument. Use
|
|
|
|
|
x2nrealloc to expand the storage.
|
|
|
|
|
(ds_reset,ds_append,ds_concat,ds_endswith): New function. (ds_fgetstr):
|
|
|
|
|
Rewrite. In particular, this fixes integer overflow. (ds_resize): Take
|
|
|
|
|
additional argument: number of bytes to leave available after ds_idx. All
|
|
|
|
|
uses changed. * src/dstring.h (dynamic_string): Keep both the allocated
|
|
|
|
|
length (ds_size) and index of the next free byte in the string (ds_idx).
|
|
|
|
|
(ds_init,ds_resize): Change signature. (ds_len): New macro.
|
|
|
|
|
(ds_free,ds_reset,ds_append,ds_concat,ds_endswith): New protos. *
|
|
|
|
|
src/copyin.c: Use new ds_ functions. (read_name_from_file): Handle len == 0.
|
|
|
|
|
(read_name_from_file): Print error message and skip file if its name is not
|
|
|
|
|
nul-terminated. (long_format): Cast rdev numbers to unsigned long *
|
|
|
|
|
src/copyout.c: Likewise. * src/copypass.c: Likewise. * src/util.c: Likewise.
|
|
|
|
|
(tape_empty_output_buffer): Fix condition. * src/idcache.c
|
|
|
|
|
(getuser,getgroup): Use umaxtostr instead of sprintf. * src/userspec.c
|
|
|
|
|
(parse_user_spec): Likewise. * configure.ac: Raise version number to 2.13.90.
