frontend: Simplified error handling.
frontend: Execute commands early on large amounts of incoming traffic.
This will free up buffer space if possible.

frontend: Fix invalid command handling when receiving data in chunks.
When skipping over invalid command data, make sure not to skip more data than
what's currently available. Rather, remember how much data needs to be ignored
and do so after actually receiving it.
Added a new test which catches these cases and also provides some more
low-level communication tests.

frontend: Treat CONNECTION_IDLE as an invalid command.
This is only meant for internal use; don't silently ignore it.

strbuf: Free memory when it's not longer needed.
While this might generate some churn in some situations, care has been taken
to avoid this as much as possible while providing a (hopefully) good balance
between memory usage and the need to reallocate memory.

ReleaseNotes: Added a summary of the utility functions.
README: Extended installation instructions a bit.
Unified project description across all documentation.
Makefile: Add ReleaseNotes to a dist tarball.
Make libsysdb and libsysdbclient private libraries for now.
The API is not yet stable enough for that purpose.
The API is not yet stable enough for that purpose.
Added initial version of the release notes.
Makefile: Added missing headers to _HEADERS variables.
sysdbd(1): Documented all signals handled by the daemon.
sysdb(7): Added a manpage providing an overview of SysDB.
sysdbql(7): Fixed a typo.
sysdb(1): Added sysdbql(7) to "see also".
sysdbql(7): Document the query language.
documentation: Unified author information.
sysdb(1): Be more verbose about the exit status when using the -c option.
coverage.sh: Refresh build system (and meta information).
integration/test_lib: Manage the sysdbd PID centrally.
This way, we actually get the right PID outside of the wrapper function and
test_lib can make sure the process is terminated on EXIT.

sysdb: Fixed incompatible pointer type warning reported by clang.
cibuild.sh: Don't run regular tests when using the address sanitizer.
valgrind does not play well with the address sanitizer. Also, there's no need
to rerun the regular tests on asan generated code (which is a test on its
own).

integration tests: Use LD_PRELOAD only when running SysDB tools.
Just as a cleanup.

tools: Log library versions as well on startup.
doc/Makefile: Added all asciidoc files to EXTRA_DIST and clean up all doc.
integration/test_lib: Pass -U mockuser to sysdb.
getpwuid_r on Travis leaks some memory which causes the valgrind tests to fail

integration tests: Use LD_PRELOAD instead of chrpath.
chrpath requires that the new path be shorter or the same length as the
previous path.

integration/simple_query: More explicitly document expected exit codes.
integration/simple_query: Added more types of simple queries.
sysdb: When handling a reply, base further actions on the response code.
This will actually enable the command handler to see whether a log message or
a query response was received.
Also, this ensures that the command handler may correctly detect errors during
query execution and exit with a non-zero code accordingly. The simple_query
integration test was updated to reflect this new, corrected behavior. Thanks
to the test for actually catching this misbehavior! :-)

sysdb: When using -c, wait for the server's final response.
There might be some intermediate log messages, which should be printed but
then we need to wait for further replies.

integration/simple_query.sh: Test a failing command.
sysdb: When using -c, exit non-zero if any command failed.

build system: Disable integration tests if valgrind or chrpath are missing.
README: Updated documentation about (integration) tests.
Merged branch 'master' of git://git.tokkee.org/sysdb.
integration/test_lib.sh: Copy binaries from $TOP_SRCDIR.
D'oh!
D'oh!
integration tests: Run all invocations through valgrind's memcheck.
… covering, both, sysdb and sysdbd. For that to work, copy the binaries and
libraries to the temp directory and change the rpath to point to the temp
directory. This ensures the test is independent of any configure flags and
installation directories.
Let the tests fail if a leak (or other error) was detected by valgrind.

sysdbd.conf(5): Documented the LoadPlugin and PluginDir options.

client: Fixed a memory leak in case connection setup fails.
t/integration/: Added variables for sysdbd/sysdb/sysdb.conf.
t/coverage.sh: Don't use --disable-shared.
Else, mock_plugin.so won't be available during 'make test'.

sysdbd: Return with status=1 in case of an initialization or config error.
frontend: Make UNIX sockets the default listener implementation.
sysdbd: Improved startup logging.
Don't log success until all initialization is actually done. Also, don't
enable the connection logger until before entering the frontend main loop.

sysdbd.conf: Added 'PluginDir' config option.
core: Make the plugin directory configurable.
dbi utils: Added compat layer for DBI < 0.9.
.gitignore: Ignore test-suite.log.
dbi utils: Use the new _r interface.
Moved unit tests into t/unit/ subdirectory.
Merged branch 'master' of git://git.tokkee.org/sysdb.
frontend: Added destructors for dynamically allocated objects in the parser.
This will make sure that the memory is freed in case of parse errors.

Instead, put the current collector object back into the list in oder to keep a

connection_test: Added a simple test for sdb_connection_accept().

utils strbuf: Don't copy more than needed in sdb_strbuf_skip().
strbuf_test: Added some more test-cases for sdb_strbuf_skip().
frontend: Always store errors in the error buffer.
This allows to access the error from other parts of the code.

store_lookup_test: Dereference objects returned from the store.
parser: Don't leak memory when building nested matchers.
backends: Destroy dbi/unixsock clients on shutdown.
This would also be cleaned up when destroying the registered user data objects
but doing so on shutdown in much cleaner.

store: Free old attribute values before storing an updated value.
collectd::unixsock plugin: Free temporarily allocated memory.
frontend: Free strdup()'ed username when destroying a connection.
sysdbd: Free up the config item returned from the parser as well.
oconfig_free() does not do that because it does not correctly keep track of
what the top-level config item is and it cannot free items which are the child
of another.

Make clang-analyze happy in two irrelevant cases.

By using the new sdb_fe_sock_clear_listeners(), the list of active listeners
may be reconfigured without affecting any open connections.

sysdbd: Free the config parse tree after finishing config work.
sysdbd: Reconfigure the daemon on SIGHUP.
The current approach shuts down the backend collector thread and the frontend.
Then, the config file is parsed again and libsysdb's reconfiguration mechanism
is used to reconfigure all plugins.

Make all plugins ready for reconfiguration support.

plugin: Added support for reconfiguring the system on the fly.
Reconfiguring all plugins happens in multiple steps:
First, call sdb_plugin_reconfigure_init() to deconfigure all plugins by
calling their config callbacks with a NULL config tree and unregistering all
registered callbacks.
Then, sdb_plugin_configure() and other functions may be used to provide the
new configuration or load new plugins. For all plugins which were already
loaded before, sdb_module_init() will be called with a NULL argument when
reloading them.
Finally, sdb_plugin_reconfigure_finish() will clean up leftover pieces, like
unloading plugins which are no longer in use.

utils llist: Added sdb_llist_clear().
This function clears the list by removing all elements and releasing the
included objects. It's similar to destroy() but does not actually release the
list object itself.

plugin: Do not expect all callbacks to have a plugin context assigned.
For callbacks not registered from a plugin, we don't have a context. For
example, the frontend's connection logger callback does not have a context.
