2019-01-04Don't call assert while checking linearization data (fixes #209, #231)Jay Berkenbilt
Instead of calling assert for problems found during checking linearization data, throw an exception which is later caught and issued as an error. Ideally we would handle errors more robustly, but this is still a significant improvement.
2018-02-19More robust handling of type errorsJay Berkenbilt
Give objects descriptions and context so it is possible to issue warnings instead of fatal errors for attempts to access objects of the wrong type.
2017-08-22Push QPDF member variables into a nested classJay Berkenbilt
Pushing member variables into a nested class enables addition of new member variables without breaking binary compatibility.
2017-08-21Enable finer grained control of stream decodingJay Berkenbilt
This commit adds several API methods that enable control over which types of filters QPDF will attempt to decode. It also adds support for /RunLengthDecode and /DCTDecode filters for both encoding and decoding.
2017-08-11Find lindict without PCREJay Berkenbilt
2017-08-11Implement findFirst and findLast in InputSourceJay Berkenbilt
Preparing to refactor some pattern searching code to use these instead of their own memchr loops. This should simplify the code that replaces PCRE.
2013-10-18Security: replace operator[] with atJay Berkenbilt
For std::string and std::vector, replace operator[] with at. This was done using an automated process. See README.hardening for details.
2013-10-10Replace some assertions with std::logic_errorJay Berkenbilt
Ideally, the library should never call assert outside of test code, but it does in several places. For some cases where the assertion might conceivably fail because of a problem with the input data, replace assertions with exceptions so that they can be trapped by the calling application. This commit surely misses some cases and replaced some cases unnecessarily, but it should still be an improvement.
2013-10-10Security: avoid pre-allocating vectors based on file dataJay Berkenbilt
In places where std::vector<T>(size_t) was used, either validate that the size parameter is sane or refactor code to avoid the need to pre-allocate the vector.
2013-10-10Security: better bounds checks for linearization dataJay Berkenbilt
The faulty code was only used during explicit checks of linearization data. Those checks are not part of normal reading or writing of PDF files.
2013-06-15Handle /Outlines dictionary being a direct objectJay Berkenbilt
Even though this case is not valid according to the spec, it has been seen, and caused an internal error.
2013-06-14Use QPDFObjectHandle::getObjGen() where appropriateJay Berkenbilt
In internal code and examples, replace calls to getObjectID() and getGeneration() with calls to getObjGen() where possible.
2013-06-14Promote QPDF::ObjGen to top-level object QPDFObjGenJay Berkenbilt
2013-03-04Remove all old-style casts from C++ codeJay Berkenbilt
2012-09-06Reset state in QPDF::calculateLinearizationDataJay Berkenbilt
This makes it possible to use two different writers to write linearized files from the same QPDF object.
2012-06-24Fix and test support for files >= 4 GBJay Berkenbilt
2012-06-22Use qpdf_offset_t in place of off_t in public APIs.Jay Berkenbilt
off_t is used internally only when needed to talk to standard libraries. This requires that the "long long" type be supported by the compiler.
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.

Fix libtests test suites to pass on Windows, mostly by dealing with ascii vs. binary and NL vs. CRNL change ($td->NORMALIZE_NEWLINES). Convert some test suites to use fread instead of read. PCRE.hh: define PCRE_STATIC if on Windows. Provide cross-platform function for getting current time instead of using time(0). git-svn-id: svn+q:///qpdf/trunk@678 71b93d88-0707-0410-a8cf-f5a4172ac649
