Jay Berkenbilt 389396dbbf Support Windows builds with MSYS2 
Replace the old msys, mingw-w64, ActiveState perl setup with MSYS2.
This greatly simplifies the Windows build. This was facilitated by the
need to incorporate JPEG.

Jay Berkenbilt b8bdef0ad1 Implement deterministic ID 
For non-encrypted files, determinstic ID generation uses file contents
instead of timestamp and file name. At a small runtime cost, this
enables generation of the same /ID if the same inputs are converted in
the same way multiple times.

Jay Berkenbilt 5c9c5d537b Update TODO with some small enhancements 
There have been a few enhancements requested that only affect the qpdf
command line tool and that should be relatively quick to implement.
Work out the details and acknowledge these publicly in the TODO file.

Jay Berkenbilt a11549a566 Detect loops in /Pages structure 
Pushing inherited objects to pages and getting all pages were both
prone to stack overflow infinite loops if there were loops in the
Pages dictionary. There is a general weakness in the code in that any
part of the code that traverses the Pages structure would be prone to
this and would have to implement its own loop detection. A more robust
fix may provide some general method for handling the Pages structure,
but it's probably not worth doing.

Note: addition of *Internal2 private functions was done rather than
changing signatures of existing methods to avoid breaking
compatibility.

Jay Berkenbilt cee2592ed1 Change API/ABI and withdraw 4.2.0 
4.2.0 was binary incompatible in spite of there being no deletions or
changes to any public methods.  As such, we have to bump the ABI and
are fixing some API breakage while we're at it.

Previous 4.3.0 target is now 5.1.0.

Jay Berkenbilt e57c25814e Support for encryption with /V=5 and /R=5 and /R=6 
Read and write support is implemented for /V=5 with /R=5 as well as
/R=6.  /R=5 is the deprecated encryption method used by Acrobat IX.
/R=6 is the encryption method used by PDF 2.0 from ISO 32000-2.
 2012-12-31 10:32:32 -05:00
Jay Berkenbilt 93ac1695a4 Support files with only attachments encrypted 
Test cases added in a future commit since they depend on /R=6 support.
