Jay Berkenbilt 3d6615b276 Pl_Buffer: reduce memory growth (fixes #228) 
Rather than keeping a list of buffers for every write, accumulate
bytes in a single buffer, doubling the size of the buffer when needed
to accommodate new data.

This is not the best possible implementation, but the change was
implemented in this way to avoid changing the shape of Pl_Buffer and
thus breaking backward compatibility.

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

Jay Berkenbilt e1cd5891af Fix infinite loop on small files with progress reporting (fixes #230) 
Turns out you can keep adding zero to a number over and over again and
it just doesn't get any bigger. Who would have known?

Jay Berkenbilt 4ccc8b1a44 Add ClosedFileInputSource

when not reading it.
 2018-06-22 12:52:45 -04:00
Jay Berkenbilt c71dc6888c Don't prune resource dictionaries on errors or by request 
If we are unable to filter a page's content streams, don't attempt to
remove objects from the page's resource dictionary. Also provide a
command line option to suppress resource removal in case we ever need
this as a workaround for some bug or broken PDF files.

Jay Berkenbilt 2e6e1204a5 Convert examples to use new page helper classes 2018-06-21 15:57:13 -04:00
Jay Berkenbilt 2e7ee23bf6 Add QPDFPageDocumentHelper and QPDFPageObjectHelper 
This is the beginning of higher-level API support using helper
classes. The goal is to be able to add more helpers without continuing
to pollute QPDF's and QPDFObjectHandle's public interfaces.
 2018-06-21 15:57:13 -04:00
Jay Berkenbilt 4cded10821 Add QPDFObjectHandle::Rectangle type 
Provide a convenient way of accessing rectangles.

Jay Berkenbilt 078cf9bf90 newline before endstream fix for object streams (fixes #205) 2018-05-12 13:17:43 -04:00
Jay Berkenbilt b4d6cf6836 Limit depth of nesting in direct objects (fixes #202) 
This fixes CVE-2018-9918.
 2018-04-15 16:11:22 -04:00
Jay Berkenbilt f8c8e4dcc0 Prepare 8.0.2 release 2018-03-06 11:34:07 -05:00
Jay Berkenbilt e4e2e26d99 Properly handle pages with no contents (fixes #194) 
Remove calls to assertPageObject(). All cases in the library that
called assertPageObject() work fine if you don't call
assertPageObject() because nothing assumes anything that was being
checked by that call. Removing the calls enables more files to be
successfully processed.

Jay Berkenbilt ee44aef8d0 Treat loop in xref tables as damage (fixes #192) 
Prior to this fix, if there was a loop detected in following /Prev
pointers in xref streams/tables, it would cause qpdf to lose data.
Note that this condition causes many PDF readers to hang or fail.

Jay Berkenbilt 6fe1e9de40 Prepare 8.0.1 release 2018-03-04 07:16:20 -05:00

Jay Berkenbilt 4bb3046f0b Properly handle strings with PDF Doc Encoding (fixes #179) 
The QPDF_String::getUTF8Val() method was not treating strings that
weren't explicitly Unicode as PDF Doc Encoded. This only affects
characters in the range 0x80 through 0xa0.

Jay Berkenbilt 2780a1871d Add C API for checking PDF files 2018-02-18 21:06:27 -05:00
Jay Berkenbilt d0e99f195a More robust handling of type errors 
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.
 2018-02-18 21:06:27 -05:00
Jay Berkenbilt c2e16827b6 Replace "file position" with "offset" in error messages 
Sometimes it's an offset in an object stream or a content stream, so
file position is confusing in some cases.
 2018-02-18 21:06:27 -05:00
Jay Berkenbilt 52e024f701 Include omitted object description in error message 2018-02-18 21:06:27 -05:00

Jay Berkenbilt 30709935af Filter tokens example 2018-02-18 21:05:47 -05:00
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.
