|

newer version of gcc and MSVC toolchains. Add several cosmetic
|
||||
improvements to build output in CI.
|
||||
|
||||
* Added LL_FMT to config.h.in. This is populated automatically by
|
||||
autoconf, but if build with your own build system, you may need to
|
||||
define it as whatever the format string needed by printf for long
|
||||
long is. Usually this is "%lld", but it can be "%I64d" for some
|
||||
older Windows-based compilers.

When concatenating content streams, as with
|
||||
<option>--coalesce-contents</option>, there were cases in
|
||||
which qpdf would merge two lexical tokens together, creating
|
||||
invalid results. A newline is now inserted between
|
||||
merged content streams if one is not already present.

Fix an internal error that could occur when copying foreign
|
||||
streams whose stream data had been replaced using a stream
|
||||
data provider if those streams had indirect filters or
|
||||
decode parameters. This is a rare corner case.

Ensure that the caller's locale settings do not change the
|
||||
results of numeric conversions performed internally by the
|
||||
qpdf library. Note that the problem here could only be
|
||||
caused when the qpdf library was used programmatically.
|
||||
Using the qpdf CLI already ignored the user's locale for
|
||||
numeric conversion.

A nearly stand-alone Linux binary zip file is now included
|
||||
with the qpdf release. This is built on an older (but
|
||||
supported) Ubuntu LTS release, but would work on most
|
||||
reasonably recent Linux distributions. It contains only the
|
||||
executables and required shared libraries that would not be
|
||||
present on a minimal system. It can be used for including
|
||||
qpdf in a minimal environment, such as a docker container.
|
||||
The zip file is also known to work as a layer in AWS Lambda.

The Windows executables distributed with qpdf releases now

use the OpenSSL crypto provider by default. The native

crypto provider is also compiled in and can be selected at

runtime with the <literal>QPDF_CRYPTO_PROVIDER</literal>

environment variable.

default.

The method <function>InputSource::unreadCh(unsigned
|
||||
char)</function> is deprecated and will be removed in qpdf
|
||||
11. It has never worked properly to pass a character to
|
||||
<function>unreadCh</function> other than the most recently
|
||||
read character. If you happen to be deriving a class from
|
||||
<type>InputSource</type>, just implement
|
||||
<function>unreadCh</function> to seek backward by one
|
||||
character if the current position is greater than 0. If you
|
||||
are calling this in your own code, replacing with
|
||||
<literal>seek(-1, SEEK_CUR)</literal> should work in all
|
||||
cases.
