Jay Berkenbilt 42d396f1dd Handle invalid name tokens symmetrically for PDF < 1.2 (fixes #332) 2019-08-19 19:48:27 -04:00
Jay Berkenbilt 45dac410b5 Remove broken QPDFTokenizer::expectInlineImage 2019-06-21 22:29:31 -04:00
Jay Berkenbilt eb49e07c0a Make inline image token exactly contain the image data 
Do not include the trailing EI, and handle cases where EI is not
preceded by a delimiter. Such cases have been seen in the wild.

Jay Berkenbilt 1eb35a355f Exclude space after ID in image data 2019-01-31 10:38:10 -05:00
Jay Berkenbilt 2b6c79bcae Improve locating inline image's EI 
We've actually seen a PDF file in the wild that contained EI
surrounded by delimiters inside the image data, which confused qpdf's
naive code. This significantly improves EI detection.

Jay Berkenbilt ec9e310c9e Refactor QPDFTokenizer's inline image handling 
Add a version of expectInlineImage that takes an input source and
searches for EI. This is in preparation for improving the way EI is
found. This commit just refactors the code without changing the
functionality and adds tests to make sure the old and new code behave
identically.

Jay Berkenbilt 4a4736c695 Fix EOL handling inside strings (fixes #226) 
CR, CRLF, and LF are all supposed to be treated as LF; only one EOL is
to be ignored after backslash.

Jay Berkenbilt 9910104442 Implement TokenFilter and refactor Pl_QPDFTokenizer 
Implement a TokenFilter class and refactor Pl_QPDFTokenizer to use a
TokenFilter class called ContentNormalizer. Pl_QPDFTokenizer is now a
general filter that passes data through a TokenFilter.

Jay Berkenbilt 2699ecf13e Push QPDFTokenizer members into a nested structure 
This is for protection against future ABI breaking changes.

Jay Berkenbilt d97474868d Lexer enhancements: EOF, comment, space 
Significant enhancements to the lexer to improve EOF handling and to
support comments and spaces as tokens. Various other minor issues were
fixed as well.

Jay Berkenbilt fabff0f3ec Limit token length during xref recovery 
While scanning the file looking for objects, limit the length of
tokens we allow. This prevents us from getting caught up in reading a
file character by character while digging through large streams.

Jay Berkenbilt ef8ae5449d Allow QPDFTokenizer::readToken to return bad tokens 
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.

Jay Berkenbilt f81152311e Add QPDFObjectHandle::parseContentStream method 
This method allows parsing of the PDF objects in a content stream or
array of content streams.
