-
Add a newline unconditionally before endstream even if a newline was already written as part of the stream data.
-
Bad /W in an xref stream could cause a division by zero error. Now this is handled as a special case.
-
Rather than checking consistency of libqpdf.map, generate it.
-
The build now checks to make sure libqpdf.map has the right library version number in it.
-
Also accept more errors than before.
-
Eliminate PCRE and find endobj not preceded by endstream. Be more lax about placement of endstream and endobj.
-
Preparing to refactor some pattern searching code to use these instead of their own memchr loops. This should simplify the code that replaces PCRE.
-
Sometimes we want to ignore bad tokens rather than having them throw an exception. A coverage case is commented out here and added in a later commit.
-
Required for strtol()
-
When parsing content streams, allow content to be split arbitrarily across stream boundaries.
-
The code was using 1.0, but we use /FlateDecode, which didn't appear until 1.2.
-
Very badly corrupted files may not have a retrievable root dictionary. Handle that as a special case so that a more helpful error message can be provided.
-
When requested, QPDFWriter will do more aggress prechecking of streams to make sure it can actually succeed in decoding them before attempting to do so. This will allow preservation of raw data even when the raw data is corrupted relative to the specified filters.
-
QPDFObjectHandle::parseInternal now issues warnings instead of throwing exceptions for all error conditions that it finds (except internal logic errors) and has stronger recovery for things like invalid tokens and malformed dictionaries. This should improve qpdf's ability to recover from a wide range of broken files that currently cause it to fail.
-
For cross compiling.

During parsing of an object, sometimes parts of the object have to be resolved. An example is stream lengths. If such an object directly or indirectly points to the object being parsed, it can cause an infinite loop. Guard against all cases of re-entrant resolution of objects.
