2019-07-04Change list to vector for outline helpers (fixes #297)Thorsten Schöning
This change works around STL problems with Embarcadero C++ Builder version 10.2, but std::vector is more common than std::list in qpdf, and this is a relatively new API, so an API change is tolerable. Thanks to Thorsten Schöning <6223655+ams-tschoening@users.noreply.github.com> for the fix.
2019-06-25Convert some cases of logic_error to runtime_errorJay Berkenbilt
There were a few cases that could be caused by invalid input rather than bugs in the code which were throwing logic_error instead of runtime_error.
2019-06-25Convert previously overlooked static cast to QIntCJay Berkenbilt
2019-06-23Add fuzzers to exercise specific pipeline classesJay Berkenbilt
2019-06-23Update TODOJay Berkenbilt
2019-06-23Treat all linearization errors as warningsJay Berkenbilt
This also reverts the addition of a new checkLinearization that distinguishes errors from warnings. There's no practical distinction between what was considered an error and what was considered a warning.

Thanks to github user zdenop for supplying some additional error-handling code.
2019-06-22In shippable code, favor smart pointers (fixes #235)Jay Berkenbilt
Use PointerHolder in several places where manually memory allocation and deallocation were being used. This helps to protect against memory leaks when exceptions are thrown in surprising places.

2019-06-22Add QUtil::read_file_into_memoryJay Berkenbilt
This code was essentially duplicated between test_driver and standalone_fuzz_target_runner.
2019-06-22QPDFWriter: clean up overloaded functionsJay Berkenbilt
In a small number of cases, it makes sense to replace an overloaded function with a function that takes a default argument. We can do this now because we've already broken binary compatibility since the last release.
2019-06-22Use clang for sanitizersJay Berkenbilt
Clang seems to be slightly stricter than gcc.
2019-06-22Convert remaining public classes to use Members patternJay Berkenbilt
Have classes contain only a single private member of type PointerHolder<Members>. This makes it safe to change the structure of the Members class without breaking binary compatibility. Many of the classes already follow this pattern quite successfully. This brings in the rest of the class that are part of the public API.

2019-06-21Fix bugs found by fuzz testsJay Berkenbilt

2019-06-21Remove implicit conversion from int/pointer to boolJay Berkenbilt
This fixes cases of warning C4800 from msvc
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.
2019-06-21Pl_Flate: constructor's out_bufsize is now unsigned intJay Berkenbilt
This is the type we need for the underlying zlib implementation.
2019-06-21Change QPDFObjectHandle::pipeStreamData's encode_flags typeJay Berkenbilt
Change from unsigned long to int since we pass enumerated type values to this field.
