* 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.
These mean to leave the original values alone. This is needed for
reconstructing streams from JSON given that the stream data and stream
dictionary may appear in any order in the JSON.
When an empty string was passed to replaceStreamData, the code was
passing a null pointer to memcpy. Since a 0 size was also passed, this
was harmless, but it triggers sanitizer errors. The code properly
handles a null pointer as the buffer in other places.
Call the parent container's item method before calling the child
item's start method so we can easily know the current nesting level
when nested items are added.
moddify -> modify. Also carefully spell checked all remaining keys by
splitting them into words and running a spell checker, not just
relying on visual proofreading. That was the only one.
This script was used on test data:
----------
#!/usr/bin/env python3
import json
import sys
import re
def json_dumps(data):
return json.dumps(data, ensure_ascii=False,
indent=2, separators=(',', ': '))
for filename in sys.argv[1:]:
with open(filename, 'r') as f:
data = json.loads(f.read())
if 'objectinfo' not in data:
continue
trailer = None
to_sort = []
for k, v in data['objectinfo'].items():
if k == 'trailer':
trailer = v
else:
m = re.match(r'^(\d+) \d+ R', k)
if m:
to_sort.append([int(m.group(1)), k, v])
newobjectinfo = {x[1]: x[2] for x in sorted(to_sort)}
if trailer is not None:
newobjectinfo['trailer'] = trailer
data['objectinfo'] = newobjectinfo
print(json_dumps(data))

This commit just changes the order in which fields are written to the
json without changing their content. All the json files in the test
suite were modified with this script to ensure that we didn't get any
changes other than ordering.

Where not possible, use "auto" to get the iterator type.
Editorial note: I have avoid this change for a long time because of
not wanting to make gratuitous changes to version history, which can
obscure when certain changes were made, but with having recently
touched every single file to apply automatic code formatting and with
making several broad changes to the API, I decided it was time to take
the plunge and get rid of the older (pre-C++11) verbose iterator
syntax. The new code is just easier to read and understand, and in
many cases, it will be more effecient as fewer temporary copies are
being made.
m-holger, if you're reading, you can see that I've finally come
around. :-)
Character transcoding from Unicode to single-byte characters used
hard-coded switch statements because the code predated our adoption of
C++11. Now we have thread-safe, static initialization of map literals,
so use that instead.
* Change DLL_EXPORT to libqpdf_EXPORTS (internal to the build). The
new name is cmake's default, is more conventional, and is less
likely to clash with other symbols.
* Add QPDF_DLL_PRIVATE for non-Windows
* Make logic around when to define QPDF_DLL et al more explicit
* Add detailed comments
Prior to the cmake conversion, several private classes had methods
that were exported into the shared library so they could be tested
with libtests. With cmake, we build libtests using an object library,
so this is no longer necessary. The methods that are disappearing from
the ABI were never exposed through public headers, so no code should
be using them. Removal had to wait until the window for ABI-breaking
changes was open.
