Jay Berkenbilt d7ffdfa994 Add optional conflict detection to mergeResources 
Also improve behavior around direct vs. indirect resources.
 2021-03-04 15:08:36 -05:00
Jay Berkenbilt e17585c2d2 Remove unreferenced: ignore names that are not Fonts or XObjects 
Converted ResourceFinder to ParserCallbacks so we can better detect
the name that precedes various operators and use the operators to sort
the names into resource types. This enables us to be smarter about
detecting unreferenced resources in pages and also sets the stage for
reconciling differences in /DR across documents.

Jay Berkenbilt b444ab3352 Fix typos in coverage cases 2021-03-03 17:05:49 -05:00
Jay Berkenbilt fa2516df71 Fix behavior for finding /Q, /DA, and /DR for form fields 
If not found in the field hierarchy, /Q and /DA are supposed to be
looked up in the document-level form dictionary. /DR is supposed to
only come from the document dictionary.

Jay Berkenbilt a4d6589ff2 Have QPDFObjectHandle notice when replaceObject was called 
This results in a performance penalty of 1% to 2% when replaceObject
and swapObjects are never called and a somewhat larger penalty if they
are called, but it's worth it to avoid very confusing behavior as
discussed in depth in qpdf#507.

Jay Berkenbilt dfce581754 Add numeric argument to --collate 
This takes pages from the file in groups of n with default = 1. This
partially fixes the enhancement in issue #505 but doesn't implement
the entire suggestion.
 2021-02-17 20:07:45 -05:00
Jay Berkenbilt a773f4c71d Add QPDFObjectHandle::parse for strings with context 2021-02-15 11:33:03 -05:00
Jay Berkenbilt efbb21673c Add functional versions of QPDFObjectHandle::replaceStreamData 
Also fix a bug in checking consistency of length for stream data
providers. Length should not be checked or recorded if the provider
says it failed to generate the data.

Jay Berkenbilt ad34b9c278 Implement helpers for file attachments 2021-02-10 06:57:37 -05:00
Jay Berkenbilt e076c9bf08 Remove erroneous handling of /EFF for stream decryption 
I thought /EFF was supposed to be used as a default for decrypting
embedded file streams, but actually it's supposed to be advice to a
conforming writer about handling new ones. This makes sense since the
findAttachmentStreams code, which is not actually needed, was never
right.

Jay Berkenbilt 21b0f4acfc Require --allow-insecure to create certain encrypted files (fixes #501) 
For now, --allow-insecure allows creation of files with the owner
passwords empty or matching the user password.
 2021-02-04 15:57:13 -05:00
Jay Berkenbilt faa2e3ddfd Handle older PDFs whose form XObjects inherit resources (fixes #494) 
When removing unreferenced resources, notice if a page (recursively)
contains a form XObject with unreferenced resources, and count any
such resources as referenced by the page.
 2021-02-02 18:06:05 -05:00
Jay Berkenbilt 5fdf37b1ba Handle warnings in --pages from other files

Jay Berkenbilt de0b11fc47 Add C++ iterator API around array and dictionary objects 2021-01-30 15:15:23 -05:00
Jay Berkenbilt 8ed3e8c79b NNTree: rework iterators to be more memory efficient 
Keep a std::pair internal to the iterators so that operator* can
return a reference and operator-> can work, and each can work without
copying pairs of objects around.

Use the first of ASCII, PDFDocEncoding, or UTF-16 that is capable of
encoding the string.

Jay Berkenbilt 63e5cb533d Use new QPDF{Name,Number}TreeObjectHelper API 2021-01-24 03:27:28 -05:00
Jay Berkenbilt d61ffb65d0 Add new constructors for name/number tree helpers

create new indirect objects.
 2021-01-24 03:27:26 -05:00
Jay Berkenbilt 5f0708418a Add iterators to name/number tree helpers 2021-01-24 03:22:59 -05:00
Jay Berkenbilt 4a1cce0a47 Reimplement name and number tree object helpers 
Create a computationally and memory efficient implementation of name
and number trees that does binary searches as intended by the data
structure rather than loading into a map, which can use a great deal
of memory and can be very slow.

Jay Berkenbilt bedf35d6a5 Bug fix: avoid extraneous pipeline finish calls with multiple contents 
Avoid calling finish() multiple times on the pipeline passed to
pipeContentStreams. This commit also fixes a bug in which qpdf was not
exiting with the proper exit status if warnings found while splitting
pages; this was exposed by a test case that changed.
 2021-01-02 14:08:17 -05:00
Jay Berkenbilt a139d2b36d Add several methods for working with form XObjects (fixes #436) 
Make some more methods in QPDFPageObjectHelper work with form
XObjects, provide forEach methods to walk through nested form
XObjects, possibly recursively. This should make it easier to work
with form XObjects from user code.

Jay Berkenbilt 12ecd2019a Add QPDFObjectHandle::setFilterOnWrite 2020-12-28 12:58:19 -05:00
Jay Berkenbilt 858c7b89bc Let optimize filter stream parameters instead of making them direct 
Also removes preclusion of stream references in stream parameters of
filterable streams and reduces write times by about 8% by eliminating
an extra traversal of the objects.
 2020-12-28 12:58:19 -05:00
Jay Berkenbilt 39bfa01307 Implement user-provided stream filters 
Refactor QPDF_Stream to use stream filter classes to handle supported
stream filters as well.

Jay Berkenbilt fbe40b800d Prepare 10.0.3 release 2020-10-31 13:47:03 -04:00
Jay Berkenbilt 96767fb104 Fix foreign stream copying bug (fixes #478) 
This reverts an incorrect fix to #449 and codes it properly. The real
problem was that we were looking at the local dictionaries rather than
the foreign dictionaries when saving the foreign stream data. In the
case of direct objects, these happened to be the same, but in the case
of indirect objects, the object references could be pointing anywhere
since object numbers don't match up between the old and new files.
 2020-10-31 12:14:26 -04:00
Jay Berkenbilt f1ae55a430 Better indirect filter test case 
The test suite now contains test cases that fail with both 10.0.1 and
10.0.2 and reproduce the internal error from #449.

Jay Berkenbilt f8e4b6161c With --no-warn, suppress warnings in split-pages 
Warnings issued on the output QPDF object were not suppressing
warnings since that option was only set on the input QPDF object.

Jay Berkenbilt 30bb4c64ee Minor code cleanup 
* Return rather than exiting from realmain in qpdf.cc
* Remove extraneous blank line
* Don't assign temporary to const reference
 2020-10-22 15:39:36 -04:00
Jay Berkenbilt 956c8f6432 Obscure bug fix copying foreign streams in special cases (fixes #449) 
Specifically, if a stream had its stream data replaced and had
indirect /Filter or /DecodeParms, it would result in non-silent loss
of data and/or internal error.
 2020-10-21 19:23:23 -04:00
Jay Berkenbilt deeface146 Add automated test for shell wildcard expansion 
Wildcard expansion is different in Windows from non-Windows and
sometimes requires special link options to work. Add tests that fail
if we link incorrectly.

Jay Berkenbilt 758e3e38f5 Add option --warning-exit-0 to exit 0 instead of 3 with warnings 2020-10-20 18:02:39 -04:00

Jay Berkenbilt ff65e272a8 Fix printf formatting for newer msvc 
Use autoconf rather than ifdefs to determine what format string to use
for long long.

Jay Berkenbilt a1994a5343 Fix/clarify documentation on --rotate option (fixes #470) 
Make clear that you almost always want + or - before an angle when
specifying rotation.
 2020-10-15 14:53:06 -04:00
Jay Berkenbilt 92d3cbecd4 Fix warnings reported by -Wshadow=local (fixes #431) 2020-04-16 12:41:43 -04:00
Jay Berkenbilt 578c5ac66c Use more references when iterating 
When possible, use `for (auto&` or `for (auto const&` when iterating
using C++-11 style iterators.

Also switch to colon-style iteration in some cases. Thanks to Dean
Scarff for drawing this to my attention after detecting some
unnecessary copies with

Jay Berkenbilt 3d0de5b924 Fixes to ChangeLog and manual for 10.0.0 changes 2020-04-06 09:02:58 -04:00
Jay Berkenbilt 0837932164 Update documentation and test suite to lock in hard page copy 
Issue #399 mentioned a use case for which qpdf has support, but the
fact that it is supported was not documented or in the test suite,
making it vulerable to accidental breakage.
 2020-04-05 20:07:13 -04:00
Jay Berkenbilt 893d38b87e Allow propagation of errors and retry through StreamDataProvider 
StreamDataProvider::provideStreamData now has a rich enough API for it
to effectively proxy to pipeStreamData.
