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 3873f5fd9b Protect headers with compliant identifiers (fixes #233) 2018-08-12 14:10:32 -04:00
Jay Berkenbilt 932799baab Fix memory access error 
A previous fix introduced a potentially memory overrun under certain
rare conditions. The test suite now once again passes with address
sanitizer.

Jay Berkenbilt b6e414b10b Remove some extraneous null pointer checks (fixes #234) 
There were a few places in the code that were checking that a pointer
wasn't null before deleting it, even though C++ has always allowed
delete 0. Most of the code did not perform these checks.
 2018-08-12 12:58:39 -04:00
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 1619cad1e8 Return correct method for string encryption (fixes #227) 2018-08-05 16:58:21 -04:00
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 4f4c627b77 ClosedFileInputSource: add method to keep file open 
During periods of intensive operation on a specific file, this method
can reduce the overhead of repeated open/close operations.

Jay Berkenbilt c81836076f Correct incorrect comment 2018-06-22 13:13:09 -04:00
Jay Berkenbilt 4ccc8b1a44 Add ClosedFileInputSource 
ClosedFileInputSource is an input source that keeps the file closed
when not reading it.

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.
 2018-06-22 10:45:31 -04:00
Jay Berkenbilt 38c9ed23c3 Treat content stream parsing errors as an error, not a warning 
If parsing content streams is treated as a warning, there is no way
for a caller to know if a parsing operation has failed. This is very
dangerous and will likely result in data loss when token filters are
parser callbacks are in use.

Jay Berkenbilt 6c89d4b35b When splitting files, remove unreferenced objects (fixes #203) 2018-06-21 21:03:30 -04:00
Jay Berkenbilt ddd78c1b7f Fix QPDFObjectHandle::shallowCopy 
It's not really a shallow copy. It just doesn't cross indirect object
boundaries. The old implementation had a bug that would cause multiple
shallow copies of the same object to share memory, which was not the
intention.

Jay Berkenbilt 0b05111db8 Implement helper class for interactive forms 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 15ed9f8565 Fix small logic error in Token construct (fixes #206) 
The special case around name token was not reachable. This would only
affect constructors of name tokens that were represented in
non-canonical form such as with a hex substitution for a printable
character. The error was harmless but still a bug.

Jay Berkenbilt b4d6cf6836 Limit depth of nesting in direct objects (fixes #202) 
This fixes CVE-2018-9918.

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.

to AppImage creation.

Jay Berkenbilt 82cae01a76 Bump version number and soname 
Bump to an alpha release. This version is not being widely released
but is being used to push the new shared library version through the
debian packaging system and to test out github releases.

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.
