2019-06-21Fix sign and conversion warnings (major)Jay Berkenbilt
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.
2013-03-05Call QUtil::safe_fopen in place of fopenJay Berkenbilt
fopen was previuosly called wrapped by QUtil::fopen_wrapper, but QUtil::safe_fopen does this itself, which is less cumbersome.
2013-03-05Mark secure CRT warnings with commentJay Berkenbilt
Put a specific comment marker next to every piece of code that MSVC gives warning 4996 for. This warning is generated for calls to functions that Microsoft considers insecure or deprecated. This change is in preparation for fixing all these cases even though none of them are actually incorrect or insecure as used in qpdf. The comment marker makes them easier to find so they can be fixed in subsequent commits.

2012-06-20ABI change: fix use of off_t, size_t, and integer typesJay Berkenbilt
Significantly improve the code's use of off_t for file offsets, size_t for memory sizes, and integer types in cases where there has to be compatibility with external interfaces. Rework sections of the code that would have prevented qpdf from working on files larger than 2 (or maybe 4) GB in size.
