      Ralph Giles authored
      Unbreaks test builds on this service.
      The Visual Studio build of the ogg library was changed
      recently to build static libraries by default, and the
      `_static` name suffix was removed. Reference this target
      when building the ogg library debpendency from a git
      checkout on the Appveyor continuous integration service.

      Update VS2015 projects for libogg.lib name change. · 51068512
      Ralph Giles authored
      Recently the ogg reference library Visual Studio build was
      updated to produce static libraries by default and the
      `_static` filename suffix was removed.
      This makes the corresponding change to the dependency
      in opusfile's Visual Studio project files for the
      example client executables. Linking against a new-style
      ogg build is now required.

      http: Fix use of deprecated function ftime() · 069dc6e8
      Mark Harris authored
      The ftime() function, introduced in V7 Unix (1979), gets the current
      time in seconds and milliseconds, and time zone information.  It was
      marked as a legacy interface in POSIX.1-2001, and removed altogether
      from POSIX.1-2008.  The gettimeofday() function, originally from
      4.1 BSD, gets the current time in seconds and microseconds, and optional
      time zone information, and was marked as obsolete in POSIX.1-2008
      although it was kept in the standard.  The POSIX recommended function
      for getting time with sub-second resolution is clock_gettime(), which
      was introduced in POSIX.1b-1993 and is now part of the base POSIX
      standard; it supports multiple clocks and nanosecond resolution.
      Additionally the function timespec_get() was introduced in C11 and also
      supports nanosecond resolution.
      To support dates beyond the year 2038, glibc and other libraries are
      being updated to support 64-bit time_t even on 32-bit architectures,
      requiring new implementations of interfaces that work with time.  As
      part of this effort, the ftime() function was deprecated in glibc 2.31
      (released February 1, 2020), a warning is now issued when building code
      that uses this function, and removal is planned for a future version of
      glibc (https://sourceware.org/pipermail/libc-announce/2020/000025.html).
      ftime() is used in http.c to measure time intervals with millisecond
      resolution.  To avoid the glibc 2.31 deprecation warning and further
      issues when the function is removed entirely from glibc, clock_gettime()
      is now used instead when it is available in the C library, as it is on
      current Linux systems.  Prior to glibc 2.17, clock_gettime() required
      linking with librt; on such systems ftime() will continue to be used, to
      avoid an additional library dependency.  macOS provides clock_gettime()
      starting in macOS 10.12; earlier versions will continue to use ftime().
      Windows provides ftime() but not clock_gettime(), so ftime() will
      continue to be used on Windows.
      ftime(), gettimeofday(), and clock_gettime() with the CLOCK_REALTIME
      clock get the "real time", which is subject to jumps if set by an
      administrator or time service.  The CLOCK_MONOTONIC clock does not have
      this problem and is more suitable for measuring time intervals.  On
      Linux, the CLOCK_BOOTTIME clock measures the time since last boot and is
      the same as CLOCK_MONOTONIC except that the Linux CLOCK_MONOTONIC clock
      does not advance when the system is suspended.  Because it is used to
      measure time intervals, CLOCK_BOOTTIME or CLOCK_MONOTONIC are used when
      available, when clock_gettime() is used.  However the only clock
      required by POSIX.1-2008 is CLOCK_REALTIME, so that will be used if the
      other clocks are not available.

      Fix handling of holes again. · 85f7aa22
      Timothy B. Terriberry authored
      It is possible for us to buffer multiple out-of-sequence pages with no packets
       on them before getting one that does have packets.
      In this case, libogg will report each hole in the page sequence numbers
      Since we were only checking for the actual packets once after encountering a
       hole, if the total number of holes was even, we could exit
       op_fetch_and_process_page() with valid packets still in the libogg buffer.
      Then, if the next page had a lot of packets, we might wind up with a total of
       more than 255 of them, overflowing our stack buffer for their durations.
      That's bad.
      Instead, make sure we always drain all hole reports from libogg any time we
       encounter one, to ensure we get the actual packets behind it.
      Thanks to Felicia Lim for the report.

      Fix to avoid technically undefined behavior. · 1bd200bc
      Timothy B. Terriberry authored
      The C standard says that calling library functions (including
       memcpy) with invalid arguments (including a NULL pointer) is
       undefined behavior unless otherwise noted (which memcpy doesn't).
      op_filter_read_native() invokes op_read_native() with NULL for the
       _pcm buffer, which triggers such a memcpy invocation.
      Even though it should be perfectly fine in practice to pass NULL to
       memcpy when copying zero bytes, don't do it.
      Thanks to a person who did not wish to be credited for the report.

      Fix seekability detection on win32. · 24cb5eae
      Timothy B. Terriberry authored
      The seeking functions on Windows internally dispatch to
       SetFilePointer(), whose behavior is undefined if you do not call
       it on "a file stored on a seeking device".
      Check the type of file when it is opened and manually force seeks
       to fail if we do not have such a file.
      Thanks to L W Anhonen for the report and Mark Harris for pointing
       out the solution used by opus-tools to avoid this problem.

      Fix SEEK_END usage in seek implementations. · 34f945bb
      Timothy B. Terriberry authored
      When seeking using SEEK_END, the win32-specific implementation of
       op_fseek() would add the offset to the file size to get the
       absolute seek position.
      However, op_mem_seek() and op_http_stream_seek() would subtract the
       offset instead.
      The documentation of fseek() is not at all clear which behavior is
       correct, but I believe that the op_fseek() behavior is.
      This inconsistency didn't matter for opusfile in practice, because
       we only ever use SEEK_END with an offset of 0.
      However, the user can also open files with our API and use the
       resulting callbacks for their own purposes, so it would be good to
       be consistent for them.
      Thanks to a person who did not wish to be credited for the report.

      http: use new API with LibreSSL >=2.7.0 · d2577d7f
      Stefan Strogin authored
      LibreSSL is not yet fully API compatible with OpenSSL 1.0.2 and later,
      However many APIs from OpenSSL 1.0.2 and 1.1 are already implemented in
      LibreSSL 2.7.0 and later. Old approach works in newer LibreSSL version
      as well, but it's not nice to force deprecated functions on LibreSSL
      Add additional conditionals for new LibreSSL versions to use the
      available new APIs.

      http: fix compilation with LibreSSL · d59a17ec
      Stefan Strogin authored
      LibreSSL defines OPENSSL_VERSION_NUMBER to 0x20000000L, but its API is
      compatible with OpenSSL 1.0.1.
      Therefore redefine OPENSSL_VERSION_NUMBER to 0x1000115fL (1.0.1u) if
      LibreSSL is used.

      Add macOS and clang builds to the travis config. · c286c605
      Stephen authored
      Improve coverage by building more variants in integration
      There's no equivalent of the apt addon for macOS builds, so
      we put dependencies in Brewfile and call `brew bundle` to
      install them. This works better than calling `brew install`
      directly since the later will error if a package is already
      installed, and even if the error is ignored it won't update
      to the latest version available, resulting in binaried built
      against e.g. vulnerable versions of openssl.
      To avoid conflicts with Apple's deprecated openssl package,
      homebrew doesn't install its openssl package in the default
      search path, so we need to manually append the its location
      to PKG_CONFIG_PATH. We cannot build against Apple's package
      because while it provides libraries and an openssl.pc file,
      no headers are available.

      Minor win32 warning fix. · dc27cf17
      Timothy B. Terriberry authored
      op_fopen() and op_freopen() declare these arguments as non-NULL,
       so when building with mingw, the compiler reasonably complains
       when we check to see if they're NULL.
      We could remove the OP_ARG_NONNULL tags, but the behavior of
       _wopen/_wfreopen appears to be to crash on NULL for either
      On Linux, the behavior appears to be to handle a NULL path (fopen
       returns NULL with errno set to EFAULT, and freopen returns the
       passed FILE * with errno set to EFAULT), but crash on a NULL mode.
      Keeping the OP_ARG_NONNULL tags promises that passing NULL results
       in undefined behavior, which is at least consistent with the
       behavior being different on different platforms.
      It's also consistent with the ABI promises of previous releases,
       which compilers linking against libopusfile might have taken
       advantage of.
