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.
|
|
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.
|
|
Pushing member variables into a nested class enables addition of new
member variables without breaking binary compatibility.
|
|
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.

Preparing to refactor some pattern searching code to use these instead
of their own memchr loops. This should simplify the code that replaces
PCRE.
|
|
For std::string and std::vector, replace operator[] with at. This was
done using an automated process. See README.hardening for details.
|
|
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.

|
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.
|
|
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.
|
|
Even though this case is not valid according to the spec, it has been
seen, and caused an internal error.
|
|
In internal code and examples, replace calls to getObjectID() and
getGeneration() with calls to getObjGen() where possible.

|
This makes it possible to use two different writers to write
linearized files from the same QPDF object.
|

|
|
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.
|
|
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.

instead of delete, thus making it useful to run valgrind over qpdf during its test suite

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).
