• This makes all integer type conversions that have potential data loss
    explicit with calls that do range checks and raise an exception. After
    this commit, qpdf builds with no warnings when -Wsign-conversion
    -Wconversion is used with gcc or clang or when -W3 -Wd4800 is used
    with MSVC. This significantly reduces the likelihood of potential
    crashes from bogus integer values.
    
    There are some parts of the code that take int when they should take
    size_t or an offset. Such places would make qpdf not support files
    with more than 2^31 of something that usually wouldn't be so large. In
    the event that such a file shows up and is valid, at least qpdf would
    raise an error in the right spot so the issue could be legitimately
    addressed rather than failing in some weird way because of a silent
    overflow condition.

  • If NO_GET_ENVIRONMENT is #defined at compile time on Windows, do not
    call GetEnvironmentVariable.  QUtil::get_env will always return
    false.  This option is not available through configure.  This was
    added to support a specific user's requirements to avoid calling
    GetEnvironmentVariable from the Windows API.  Nothing in qpdf outside
    the test coverage system in qtest relies on QUtil::get_env.

  • Breaking API change: length parameter has disappeared from the
    StreamDataProvider version of QPDFObjectHandle::replaceStreamData
    since it is no longer necessary to compute it in advance.  This
    breaking change is justified by the fact that removing the length
    parameter provides the caller an opportunity to simplify the calling
    code.
