+
+ * ctf-create.c (ctf_compress_write): Fix double-free.
+
+2019-07-13 Nick Alcock <nick.alcock@oracle.com>
+
+ * ctf-archive.c (ctf_arc_write): Split off, and reimplement in terms
+ of...
+ (ctf_arc_write_fd): ... this new function.
+ * ctf-create.c (ctf_write_mem): New.
+
+2019-07-13 Nick Alcock <nick.alcock@oracle.com>
+
+ * ctf-impl.h (ctf_str_atom_t) <csa_offset>: New field.
+ (ctf_file_t) <ctf_syn_ext_strtab>: Likewise.
+ (ctf_str_add_ref): Name the last arg.
+ (ctf_str_add_external) New.
+ (ctf_str_add_strraw_explicit): Likewise.
+ (ctf_simple_open_internal): Likewise.
+ (ctf_bufopen_internal): Likewise.
+
+ * ctf-string.c (ctf_strraw_explicit): Split from...
+ (ctf_strraw): ... here, with new support for ctf_syn_ext_strtab.
+ (ctf_str_add_ref_internal): Return the atom, not the
+ string.
+ (ctf_str_add): Adjust accordingly.
+ (ctf_str_add_ref): Likewise. Move up in the file.
+ (ctf_str_add_external): New: update the csa_offset.
+ (ctf_str_count_strtab): Only account for strings with no csa_offset
+ in the internal strtab length.
+ (ctf_str_write_strtab): If the csa_offset is set, update the
+ string's refs without writing the string out, and update the
+ ctf_syn_ext_strtab. Make OOM handling less ugly.
+ * ctf-create.c (struct ctf_sort_var_arg_cb): New.
+ (ctf_update): Handle failure to populate the strtab. Pass in the
+ new ctf_sort_var arg. Adjust for ctf_syn_ext_strtab addition.
+ Call ctf_simple_open_internal, not ctf_simple_open.
+ (ctf_sort_var): Call ctf_strraw_explicit rather than looking up
+ strings by hand.
+ * ctf-hash.c (ctf_hash_insert_type): Likewise (but using
+ ctf_strraw). Adjust to diagnose ECTF_STRTAB nonetheless.
+ * ctf-open.c (init_types): No longer filter out ECTF_STRTAB.
+ (ctf_file_close): Destroy the ctf_syn_ext_strtab.
+ (ctf_simple_open): Rename to, and reimplement as a wrapper around...
+ (ctf_simple_open_internal): ... this new function, which calls
+ ctf_bufopen_internal.
+ (ctf_bufopen): Rename to, and reimplement as a wrapper around...
+ (ctf_bufopen_internal): ... this new function, which sets
+ ctf_syn_ext_strtab.

+
+ * ctf_types.c (ctf_type_iter_all): New.
+
+2019-07-13 Nick Alcock <nick.alcock@oracle.com>
+
+ * ctf-open.c (init_symtab): Check for overflow against the right
+ section.
+ (upgrade_header): Set cth_objtidxoff, cth_funcidxoff to zero-length.
+ (upgrade_types_v1): Note that these sections are not checked.
+ (flip_header): Endian-swap the header fields.
+ (flip_ctf): Endian-swap the sections.
+ (flip_objts): Update comment.
+ (ctf_bufopen): Check header offsets and alignment for validity.
+
+2019-07-13 Nick Alcock <nick.alcock@oracle.com>
+
+ * ctf-open-bfd.c: Add <assert.h>.
+ (ctf_bfdopen_ctfsect): Open string and symbol tables using
+ techniques borrowed from bfd_elf_sym_name.
+ (ctf_new_archive_internal): Improve comment.
+ * ctf-archive.c (ctf_arc_close): Do not free the ctfi_strsect.
+ * ctf-open.c (ctf_bufopen): Allow opening with a string section but
+ no symbol section, but not vice versa.
+
+2019-07-08 Nick Alcock <nick.alcock@oracle.com>
+
+ * ctf-impl.h (ctf_file_t): New field ctf_openflags.
+ * ctf-open.c (ctf_bufopen): Set it. No longer dump header offsets.
+ * ctf-dump.c (dump_header): New function, dump the CTF header.
+ (ctf_dump): Call it.
+ (ctf_dump_header_strfield): New function.
+ (ctf_dump_header_sectfield): Likewise.
+
+2019-07-06 Nick Alcock <nick.alcock@oracle.com>
+
+ * ctf-impl.h (ctf_file_t): New fields ctf_header, ctf_dynbase,
+ ctf_cuname, ctf_dyncuname: ctf_base and ctf_buf are no longer const.
+ * ctf-open.c (ctf_set_base): Preserve the gap between ctf_buf and
+ ctf_base: do not assume that it is always sizeof (ctf_header_t).
+ Print out ctf_cuname: only print out ctf_parname if set.
+ (ctf_free_base): Removed, ctf_base is no longer freed: free
+ ctf_dynbase instead.
+ (ctf_set_version): Fix spacing.
+ (upgrade_header): New, in-place header upgrading.
+ (upgrade_types): Rename to...
+ (upgrade_types_v1): ... this. Free ctf_dynbase, not ctf_base. No
+ longer track old and new headers separately. No longer allow for
+ header sizes explicitly: squeeze the headers out on upgrade (they
+ are preserved in fp->ctf_header). Set ctf_dynbase, ctf_base and
+ ctf_buf explicitly. Use ctf_free, not ctf_free_base.
+ (upgrade_types): New, also handle ctf_parmax updating.
+ (flip_header): Flip ctf_cuname.
+ (flip_types): Flip BUF explicitly rather than deriving BUF from
+ BASE.
+ (ctf_bufopen): Store the header in fp->ctf_header. Correct minimum
+ required alignment of objtoff and funcoff. No longer store it in
+ the ctf_buf unless that buf is derived unmodified from the input.
+ Set ctf_dynbase where ctf_base is dynamically allocated. Drop locals
+ that duplicate fields in ctf_file: move allocation of ctf_file
+ further up instead. Call upgrade_header as needed. Move
+ version-specific ctf_parmax initialization into upgrade_types. More
+ concise error handling.
+ (ctf_file_close): No longer test for null pointers before freeing.
+ Free ctf_dyncuname, ctf_dynbase, and ctf_header. Do not call
+ ctf_free_base.
+ (ctf_cuname): New.
+ (ctf_cuname_set): New.
+ * ctf-create.c (ctf_update): Populate ctf_cuname.
+ (ctf_gzwrite): Write out the header explicitly. Remove obsolescent
+ comment.
+ (ctf_write): Likewise.
+ (ctf_compress_write): Get the header from ctf_header, not ctf_base.
+ Fix the compression length: fp->ctf_size never counted the CTF
+ header. Simplify the compress call accordingly.

* ctf-endian.h: Don't assume htole64 and le64toh are always
