This removes all chromium dependencies from media/base/ and completes
the build system in CMake.
The ClosureThread class and its classes were removed, as they were
specific to chromium base. ClosureThread has been replaced by
std::thread.
The byte-swapping utilities in network_util.cc have been removed and
replaced with absl.
generate_unique_temp_path() was split out of file_unittest.cc into
file_test_util.cc, where other test suites could make use of it.
WARN_UNUSED_RESULT was replaced with the C++ standard attribute
[[nodiscard]].
The base::Clock interface was replaced with a typedef for a function
pointer that returns the current time.
This re-enables the tests in http_key_fetcher_unittest.cc by using
httpbin.org.
Issue #1047 (CMake porting)
Issue #346 (absl porting)
This also normalizes the structure of all submodule folders so that
there is a clear place to put configurations, outside the submodule
source, but limited in scope to that folder.
Issue #1047 (New build system)
This removes apple_apsl and libevent (which are no longer used) and
libxml and protobuf (which will be replaced in a follow-up with
submodules).
This change only contains deletions, to make it easier to review
separately from later additions for submodules and cmake integration.
Issue #1047 (New build system)
There are a lot of changes in this first phase, because there was a
lot of infrastructure required to get some meaningful amount of
porting done. Future PRs should be simpler.

Issue #346 (Switch to abseil)
Issue #1047 (New build system)
The official, static-linked linux builds were crashing in their use of
getaddrinfo, which libcurl was configured to use. Both getaddrinfo
and all of its alternatives available in glibc fail with static
linking.
We can fix this by configuring libcurl to use libc-ares on Linux
instead. This allows us to keep the benefits of a statically-linked
Linux binary.
Closes#996

The newest pylint release complained about several issues that the
older release did not. This resolves those issues:
- removes unneeded "u" prefix from strings
- adds "encoding" parameter for all open() calls
- because "encoding" is a python3-only parameter, use python3 in all
the scripts that we control
Unfortunately, python2 is required for any scripts that import modules
from the ancient Chromium build system we're using (referenced by
DEPS), as well as kokoro scripts.

This fixes the Debug build of libpng on arm64 by avoiding CPU-specific
optimizations that are not in our sources list. The Release build
appears to have been unaffected, possibly due to link-time
optimizations or dead code stripping.

This brings our default build config more in line with what is
necessary for some platforms anyway: using the system-installed
toolchain and sysroot to build everything.
We will no longer fetch source or binaries for any specific build
tools, such as libc++, clang, gold, binutils, or valgrind.
The main part of this change is the changing of default gyp settings
in gyp_packager.py. For this, a bug in gyp_packager.py had to be
fixed, in which similar GYP_DEFINE key names (such as clang and
host_clang) would conflict, causing some defaults not to be installed
properly.
In order to enable clang=0 by default, some changes had to be made in
common.gypi:
- compiler macros added to fix a compatibility issue between
Chromium's base/mac/ folder and the actual OSX SDK
- replaced clang_warning_flags variables with standard cflags
settings, plus xcode_settings for OSX
- turned off warnings-as-errors for non-shaka code, rather than
allow-listing specific warning types, since we can't actually fix
those warnings on any platform
- disabled two specific warnings in shaka code, both of which are
caused by headers from our non-shaka dependencies
Also, one warning (missing "override" keyword) has been fixed in
vod_media_info_dump_muxer_listener.h.
Although these changes were done to make building simpler on a wider
array of platforms (arm64, for example), it seems to make the build a
bit faster, too. For me, at least, on my main Linux workstation:
- "gclient sync" now runs 20-30% faster
- "ninja -C out/Release" now runs 5-13% faster
The following environment variables are no longer required:
- DEPOT_TOOLS_WIN_TOOLCHAIN
- MACOSX_DEPLOYMENT_TARGET
Documentation, Dockerfiles, and GitHub Actions workflows have been
updated to reflect this.
The following GYP_DEFINES are no longer required for anyone:
- clang=0
- host_clang=0
- clang_xcode=1
- use_allocator=none
- use_experimental_allocator_shim=0
Documentation, Dockerfiles, and GitHub Actions workflows have been
updated to reflect this.
The following repos are no longer dependencies in gclient:
- binutils
- clang
- gold
- libc++
- libc++abi
- valgrind
The following gclient hooks have been removed:
- clang
- mac_toolchain
- sysroot

Also roll_boringssl.py script is also adjusted to work with latest
boringssl.
Disable ASM compilation on Windows x64 which fails to compile. It also
means there are no HW AES on Windows x64.
Issue #198.

With the update, the script needs to be launched from
out/{Debug,Release} directory.
Also updated docs to make it clear how to use the tool.
Fixes#538.

- Update curl to 7.57.0
- Roll clang, which is needed due to MacOS / XCode update
- Fixes and suppress compilation errors due to clang update
Fixes#285

Seeing some failures on some platforms when compiled with clang
disabled:
GYP_DEFINES="clang=0" gclient runhooks
Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
direct control: dangling-else, deprecated-declarations,
unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
all linux distributions.

Cues used to be generated in the end of the file; if http range
request is not supported, clients have to download the whole
file to get to the cues.
This CL updated TwoPassSingleSegmentSegmenter to write cues
after writing webm header.
This CL also updates libwebm dependency to latest.
Closes#159

WebRTC portion (gyp build) now checked in because separate repository is no longer available due to transition to git.
Change-Id: I56436cbbc3f02a5f77112917d6229aea69f21d97
Create a new MacOSX configuration for curl:
- Add a curl_config.h created on MacOSX
- Add a find_curl_ca_bundle.sh that searches default folder from Homebrew and MacPorts for a ca bundle.
To find the files either install OpenSSL from Homebrew or MacPorts, or Curl from MacPorts.
When generating ninja files we end up with two libwebm targets.
packager/media/formats/webm/webm.gyp:webm -> becomes target libwebm
packager/third_party/libwebm/libwebm.gyp:libwebm -> becomes target libwebm
Solve this conflict by renaming libwebm.gyp:libwebm to mkvmuxer.
Find curl_ca_bundle script is used by linux only. Move it out of
gyp and make sure it runs only in linux.
Also make zlib deps generic for all systems, not for linux only.
This is the first step of getting edash_packager builds on Windows
and Mac.

Fix "Problem with the SSL CA cert" issue @
https://github.com/google/edash-packager/issues/6. On Ubuntu, CURL_CA_BUNDLE
is located at "/etc/ssl/certs/ca-certificates.crt" while on CentOs, it is
located at "/etc/ssl/certs/ca-bundle.crt".
With this change, GYP scans the common appearing locations for SSL CA cert.
