libredwg-0.10 released

Item posted by Reini Urban <reini_urban> on Wed 08 Jan 2020 04:52:15 PM UTC.

Some minor API changes and bugfixes, mostly stabilization.

API breaking changes:
  * added a new int *isnewp argument to all dynapi utf8text getters,
    if the returned string is freshly malloced or not.
  * removed the UNKNOWN supertype, there are only UNKNOWN_OBJ and UNKNOWN_ENT
    left, with common_entity_data.
  * renamed BLOCK_HEADER.preview_data to preview, preview_data_size to preview_size
  * renamed SHAPE.shape_no to style_id
  * renamed CLASS.wasazombie to is_zombie

Major bugfixes:
  * Improved building the perl5 binding, proper dependencies.
    Set proper -I and -L paths, create LibreDWG.c not swig_perl.c
  * Harmonized INDXFB with INDXF, removed extra src/in_dxfb.c (#134).
    Slimmed the .so size by 260Kb. Still untested though.
  * Fixed encoding of added r2000 AUXHEADER address (broken since 0.9)
  * Fixed EED encoding from dwgrewrite (a dxf2dwg regression from 0.9) (#180)

Minor bugfixes:
  * Many fuzzing and static analyzer fixes for dwg2dxf, dxf2dwg, dwgrewrite,
    including a stack-overflow on outdxf cquote. (#172-174, #178, #179).
    dwgrewrite and indxf are pretty robust now, but still highly experimental,
    as many dxf2dwg import and DWG validity tests are missing.
    indxf still has many asserts on many structural DXF errors.
  * Protect indxf from many NULL ptr, overflows and truncation.
  * Fixed most indxf and encode leaks. (#151)
  * More section decoders protections from invalid (fuzzed) values.
  * Stabilized the ASAN leak tests for make check.
  * Fix MULTILEADER.ctx.lline handles <r2010
  * Fix indxf color.alpha; at DXF 440
  * Fixed most important make scan-build warnings, the rest are mostly bogus.

Other newsworthy changes:
  * Added LIBREDWG_VERSION et al to include/dwg.h
  * Added support for AcDb3dSolid history_id (r2007+)
  * Improved the indxf speed in new_object. Do a proper linear search, and
    break on first found type.
  * Rename the ./dxf helper to ./dwg, and added a ./dxf test helper.
  * dxf2dwg got a new experimental --force-free option to check for leaks and
    UAF or double-free's.
  * Allow -o /dev/null sinks for dxf2dwg and dwg2dxf, for faster fuzzing.
  Harmonized .spec formatting and adjusted gen-dynapi.pl
  * Harmonized out_dxfb with out_dxf, e.g. the new mspace improvements (#173).

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify libredwg-0.10.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys B4F63339E65D6414

and rerun the 'gpg --verify' command.
