Previously, options were being filtered based on what was currently valid. For chained commands (e.g. backup then expire) some options may be valid for the first command but not the second.
Filter based on the command definition rather than what is currently valid to avoid logging options that are not valid for subsequent commands. This reduces the number of options logged and will hopefully help avoid confusion and expect log churn.
Pre-calculate the value used by logAny() to improve performance and make it more likely to be inlined.
Move IF_LOG_ANY() into LOG_INTERNAL() to simplify the macros and improve performance of LOG() and LOG_PID(). If the message has no chance of being logged there's no reason to call logInternal().
Rename logWill() to logAny() because it seems more intuitive.
Use autoconf to provide a basic configure script. WITH_BACKTRACE is yet to be migrated to configure and the unit tests still use a custom Makefile.
Each C file must include "build.auto.conf" before all other includes and defines. This is enforced by test.pl for includes, but it won't detect incorrect define ordering.
Update packages to call configure and use standard flags to pass options.
Rename FUNCTION_DEBUG_* macros to FUNCTION_LOG_* to more accurately reflect what they do. Further rename FUNCTION_DEBUG_RESULT* macros to FUNCTION_LOG_RETURN* to make it clearer that they return from the function as well as logging. Leave FUNCTION_TEST_* macros as they are.
Consolidate the various ASSERT* macros into a single ASSERT macro that is always compiled out of production builds. It was difficult to figure out when an assert would be checked with all the different types in play. When ASSERTs are compiled in they will always be checked regardless of the log level -- tying these two concepts together was not a good idea.
A return code of 1 from the archive-get was being logged as an error message at info level but otherwise worked correctly.
Also improve info messages when an archive segment is or is not found.
Low-level functions only include stack trace in test builds while higher-level functions ship with stack trace built-in. Stack traces include all parameters passed to the function but production builds only create the parameter list when the log level is set high enough, i.e. debug or trace depending on the function.
The Perl process was exiting directly when called but that interfered with proper locking for the forked async process. Now Perl returns results to the C process which handles all errors, including signals.
Move command begin to C except when it must be called after another command in Perl (e.g. expire after backup). Command begin logs correctly for complex data types like hash and list. Specify which commands will log to file immediately and set the default log level for log messages that are common to all commands. File logging is initiated from C.
