Replacement of internal RegEx with PCRE2
|
|
|
|
|
|
|
|
It is now dual-licensed BSD-3-Clause and GPL-2.0, we use the former.
The PATENTS file is no longer applicable \o/
Also add zstd to COPYRIGHT.txt
|
|
Also fix documented OpenSSL version, it was updated to 1.0.2l in
67305d1b0a6dbcdb032d5a5a0e92122cf8f10b8d.
|
|
Fixes security vulnerability in our 1.6.31rc01 snapshot.
|
|
Fixes #10539 in a diplomatic way (as opposed to telling Gentoo users
to just change their distro or rebuild zlib from upstream...).
|
|
|
|
The pattern and replacement matching behaviour has been changed purely
due to the nature of switching to a standards-compliant library.
One mistake in the previous behaviour was that named groups didn't have
a number. This has been corrected.
As names are actually just an alias of numbered groups,
RegExMatch::get_name_dict() is now get_names() and is a dict
referring to the group number it represents.
Duplicate names are enabled and the with the first matching instance
used.
Due the lack of a suitable equivalent in PCRE2, RegExMatch::expand() was
removed.
|
|
I have not assessed whether they are still all relevant.
|
|
Godot-specific changes are undone in this commit, they will be readded
and properly documented in the following commit.
|
|
-Fixed bugs regarding tangent generation in SurfaceTool
|
|
Following upstream commit f04deff4fc
|
|
|
|
Fixes various issues with 1.6.30, especially ARM build.
Supersedes change in #9722.
|
|
This commit fixes errors occurring during Android export template
builds.
This required modification in third-party library (libpng) to compile
with NEON. Most likely a similar patch will be applied by them and we
could then replace the modified version.

|
This reverts commit 8b362b50094ccd332c6ee3d0853a6b9b49f70253.
We should not apply our clang-format style to thirdparty code,
it makes it impossible to maintain.

Add ETC1/ETC2 compression support though etc2comp.
|
|
zstd has much better compression speed and ratio, and better decompression speed than currently available methods.
Also set zstd as the default compression method for Compression as well as FileAccessCompressed functions.
|
|
Remove rg-etc1 code. Also updated travis to use ubuntu 14.04.
Fixes #8457.
|
|
|
|
|
|
|
|
This avoids namespace collisions with things such as X509_NAME.
Also force include of necessary definitions in `crypto/o_str.c`
which seem missing on MSVC (but work on MinGW).
|
|
Our necessary custom changes will be reapplied in later commits for clarity,
and saved as patches for future updates.
|
|
|
|
|
|
MinGW-w64 is at version 2.0.1 on our current Travis CI toolchain, and seems
not to like fopen_s.
|
|
-Improvements to texture importer
-Proper detection of S3TC compression modes, and added all modes to Image
-Fixes to non-power of 2 compressed textures, which should all be supported by GLES3
|
|
|
|
Also move Box2D ConvexDecomposition contrib code to
thirdparty/b2d_convexdecomp.

Code comes from https://github.com/antirez/smaz/blob/150e125cbae2e8fd20dd332432776ce13395d4d4/smaz.c
With a small modification to match Godot expectations:

Also fix clang-format pre-commit hook to ignore thirdparty files.

- Add blocking mode option to PacketPeerUDP.
- put_packet returns ERR_UNAVAILABLE when operation would block.
- ENet module uses non-blocking UDP.
