Two changes were made recently for the batch processing component
in scanimage. It's not too bad, just a couple of unused local vars.
Conflict was between some refactoring that I did and a change to
the processing for --batch-prompt.
We have been specially including libgen.h to get a version in other
platforms such as macOS and FreeBSD. However, it is dangerous to
make assumptions about which version of basename that we will get.
So this change reverts to asking for the version that modifies the
argument and creates a copy of the arg that we *can* modify.
HPAIO backend in some instances provides options that have NULL name.
It might be that it is using SETTABLE flag to disable options rather
than removing them from the options list. Or it might just be a
backend bug.
- reduce scope of some variables
- move full_optstring to global so that scanimage_exit can clean it up
- initialize global variables. Global statics are not initialized.
- some other more minor things
The saned(8) man page should be used to describe the behavior of saned
itself. The information about configuring inetd, xinetd, or systemd to
launch saned - while it is helpful - belongs in a separate location.
Keep in mind that distribution packages usually configure the service
automatically, and they may ship with their own specific instructions.
(For example, update-inetd can be used in Debian and its derivatives.)
This change moves this information from the man page into a new file,
making it more concise as well. Working examples are moved to separate
files that can be copied directly from the source tree to the system.
These were intended to suppress GCC warnings about unused variables.
However, this leads to different warnings from Clang instead.
Use another approach that suppresses warnings from both compilers.
With the exception of use in three quotes as well as our inlcuded copy
of the GPL, all use of the Free Software Foundation's postal address
has been removed.
Re #320.
We have seen this from buggy backends that present NULL for constraint
string_lists. This is probably illegal behaviour from backends but we
don't want to crash.
h5400 now checks validity of -l, -t, -x and -y and auto selects a supported resolution.
scanimage now shows the full range for -x and -y despite other selections.
This creates temporary strings that correspond to the colon-delimited
username and password that are read from file in `auth_callback()`.
The null-terminated strings are used directly to determine lengths.
The AX_CXX_COMPILE_STDCXX* macros that were embedded in aclocal.m4
have been replaced with the versions found in the autoconf-archive
package from Debian 9.
