Werner Lemberg 2d9fce53d4 [gzip] Update sources to zlib 1.13. 2023-08-27 09:47:24 +02:00
David Vanderson ace97a02a4 [gzip] Make static compilation not leak global symbols.
* src/gzip/ftgzip.c (HAVE_HIDDEN): Do not define; it is no longer needed
because everything is static.
(HAVE_MEMCPY): Define.
(zcalloc, zcfree): Remove no longer needed definitions (because `Z_SOLO` is
active).

* src/gzip/patches/freetype-zlib.diff: Regenerated.

Fixes #1146.

Werner Lemberg 1603378b91 [gzip] Update sources to zlib 1.2.12. 2022-04-01 10:47:23 +02:00
Werner Lemberg 3f9b78fc79 [zlib] Don't typedef `ptrdiff_t`.
While using zlib in 'solo' mode (via the `Z_SOLO` macro), we actually
include some standard header files, making the typedef fail on systems where
the native `ptrdiff_t` type differs.

Fixes #1124.

* src/zlib/zutil.h: Comment out definition; it doesn't work on Windows.

* src/zlib/patches/freetype-zlib.diff: Updated.

Werner Lemberg da8a8b8bcf [zlib] Some organizational changes.
We now first apply zlib's `zlib2ansi` script, then FreeType's patch file.

* src/gzip/README.freetype: Updated.

* patches/0001-zlib-Fix-zlib-sources-to-compile-for-FreeType.patch: Renamed
to...
* patches/freetype-zlib.diff: This.
Clean up description, then regenerate it as follows:

  - Copy unmodified files from `zlib` repository.
  - Run `zlib2ansi` script.
  - Run `git diff -R > patches/freetype-zlib.diff.new`.
  - Insert patch description of old diff file, then replace old diff with
    new diff file.

David Turner a25e85ed95 [gzip] Update sources to zlib 1.2.11
This can be tested by building with the Unix development build

  make setup devel
  make

or by building the freetype-demos programs with

  meson setup build -Dfreetype2:zlib=internal
  meson compile -C out

and trying to run `ftview` with a `.pcf.gz` font file.

* src/gzip/ftgzip.c, src/gzip/rules.mk: Update for new zlib sources.  Also
remove the temporary fix introduced in commit 6a431038 to work around the
fact that the internal sources were too old.

* src/gzip/README.freetype: New file describing the origin of the sources
and how they were modified.

* src/gzip/patches/*: Patch files applied to original sources.

* src/gzip/*: Updated zlib sources with the patch file(s) from
`src/gzip/patches/` applied, followed by a conversion with zlib's
`zlib2ansi` script.
