  13 2019-06-28  Nick Alcock <nick.alcock@oracle.com>
  14
  15         * ctf-impl.h: (struct ctf_strs_writable): New, non-const version of
  16         struct ctf_strs.
  17         (struct ctf_dtdef): Note that dtd_data.ctt_name is unpopulated.
  18         (struct ctf_str_atom): New, disambiguated single string.
  19         (struct ctf_str_atom_ref): New, points to some other location that
  20         references this string's offset.
  21         (struct ctf_file): New members ctf_str_atoms and ctf_str_num_refs.
  22         Remove member ctf_dtvstrlen: we no longer track the total strlen
  23         as we add strings.
  24         (ctf_str_create_atoms): Declare new function in ctf-string.c.
  25         (ctf_str_free_atoms): Likewise.

  35         * ctf-create.c (ctf_update): Copy-and-free it on update.  No longer
  36         special-case the position of the parname string.  Construct the
  37         strtab by calling ctf_str_add_ref and ctf_str_write_strtab after the
  38         rest of each buffer element is constructed, not via open-coding:
  39         realloc the CTF buffer and append the strtab to it.  No longer
  40         maintain ctf_dtvstrlen.  Sort the variable entry table later, after
  41         strtab construction.
  42         (ctf_copy_membnames): Remove: integrated into ctf_copy_{s,l,e}members.
  43         (ctf_copy_smembers): Drop the string offset: call ctf_str_add_ref

  55         * ctf-util.c (ctf_realloc): New, wrapper around realloc that aborts
  56         if there are active ctf_str_num_refs.
  57         (ctf_strraw): Move to ctf-string.c.
  58         (ctf_strptr): Likewise.
  59         * ctf-string.c: New file, strtab manipulation.

  88         (ctf_fdopen): Check for endian-swapped raw CTF magic, and
  89         little-endian CTF archive magic.  Do not check the CTF version:
  90         ctf_simple_open does that in endian-safe ways.  Do not dereference
  91         null pointers on open failure.
  92
  93 2019-06-19  Nick Alcock <nick.alcock@oracle.com>
