Jay Berkenbilt f1a2d3160a Add JSON v2 support to C API 2022-09-09 06:19:09 -04:00
Jay Berkenbilt 66f1fd2ad9 Switch user-supplied functions in C API to return int 2022-09-08 17:36:51 -04:00
Jay Berkenbilt b0f054e600 Add ability to initialize Pl_Function with a C-style function 2022-09-08 17:35:27 -04:00
Jay Berkenbilt 18a583e8d9 Rename QPDFValueProxy back to QPDFObject 
QPDFValueProxy wasn't a good name for it. We decided the evil of
having the header file be named QPDFObject_private.hh was less than
the evil of having the class be named something other than what it
should have been named.

Jay Berkenbilt 25ccc7eae4 Rename QPDFValueProxy.hh and QPDFValueProxy.cc 
Preparing to change the class name back to QPDFObject
 2022-09-08 11:19:49 -04:00
Jay Berkenbilt c7a4967d10 Change reset to disconnect and clarify comments 
I decided that it's actually fine to copy a direct object to another
QPDF. Even if we eventually prevent a QPDFObject from having multiple
parents, this could happen if an object is moved.
 2022-09-08 11:06:15 -04:00
Jay Berkenbilt dba61da1bf Create a special "destroyed" type rather than using null 
When a QPDF is destroyed, changing indirect objects to direct nulls
makes them effectively disappear silently when they sneak into other
places. Instead, we should treat this as an error. Adding a destroyed
object type makes this possible.

Jay Berkenbilt 264e25f391 Clear owning QPDF information for all objects, not just indirect 2022-09-08 10:19:38 -04:00
Jay Berkenbilt a615985865 Update QPDFObject with comment 
Also, since it's just there for compatibility, we don't need to add
new object types to it.

Jay Berkenbilt 259eec3a94 Clarify comments for QPDFObjectHandle::getOwningQPDF 2022-09-06 10:09:28 -04:00
Jay Berkenbilt 55cc2ab680 Re-introduce QPDFObject.hh as deprecated 
* Just removing a header file would cause build errors with no hint as
  to what happened. This way, people get a warning rather than error
  for the life of qpdf 11, and the warning tells them what to do.

* This avoids build surprises resulting from having two versions of
  QPDF headers installed at once. If you were building code out of a
  checkout of qpdf but had an older version installed on your system,
  if your code included <qpdf/QPDFObject.hh>, everything would work,
  but then your code would break without QPDFObject.hh later.

Jay Berkenbilt 6c61be00e8 Rename QPDFObject -> QPDFValueProxy 
This is in preparation for restoring a QPDFObject.hh to ease the
transition on qpdf_object_type_e.

This commit was created by
* Renaming QPDFObject.cc and QPDFObject.hh
* Replacing QPDFObject\b with QPDFValueProxy (where \b is word
  boundary)
* Running format-code
* Manually resorting files in libqpdf/CMakeLists.txt
* Manually refilling the comment in QPDF.hh near class Resolver

Jay Berkenbilt 0a7ba62b00 Update formatting a documentation from last PR 2022-09-05 18:52:59 -04:00
James R. Barlow 12967bdf8a Take advantage of unique_ptr and move construction for Buffer 
Since Buffer has always implemented its copy constructor with a deep
copy, its Members object will never have multiple owners. Change to unique_ptr.

Also implement move constructors for Buffer, since there may be cases
where a deep copy is not needed.

m-holger 9c86ba40d8 Fix commit 805c1ad : Reset QPDFValue::qpdf and QPDFValue::og when ... 
On destruction of the QPDF object replace all indirect object references
with direct nulls.

Remove all existing code to release resolved references.

Fixes performance issue due to interaction of resetting QPDFValue::qpdf and
og members and prior code.

* Replace --create-from-json=file with --json-input, which causes the
  regular input to be treated as json.
* Eliminate --to-json
* In --json=2, bring back "objects" and eliminate "objectinfo". Stream
  data is never present.
* In --json-output=2, write "qpdf-v2" with "objects" and include
  stream data.

Jay Berkenbilt 63c7eefe9d replaceStreamData: accept uninitialized filter/decode_parms

Jay Berkenbilt cb769c62e5 WHITESPACE ONLY -- expand tabs in source code 
This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.

In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.
