- make "debug.h" a private header so that the DEBUG() macro does not
interfere with Xcode Debug builds, which set DEBUG=1
- move all #include "debug.h" from headers into .c files
- move 'struct idebug' into a new public header "idebug.h" so that
"log.h" can be public
- move HTTPD port number defs from "httpd.h" to "constants.h", so that
"httpd.h" can be private and "conf.h" can be public
- add missing nested includes so each header compiles stand-alone
without error
- #include "sodium.h" instead of <sodium.h>
- #include "sqlite3.h" instead of <sqlite3.h>
- add header guard to "fifo.h"
- fix header guard in "sync_keys.h"
Rename the logging primitive functions and utility functions, prefixing
all with 'serval_log', eg: logMessage() -> serval_logf() etc.
Add an XPRINTF xhexdump() function and use it to implement the
serval_log_hexdump() utility, renamed from dump(). Add macros
WHY_dump(), WARN_dump(), HINT_dump() and DEBUG_dump(), and use them
everywhere.
Remove the 'log.console.dump_config' and 'log.file.dump_config'
configuration options; configuration is now dumped in every log prolog.
The logging system now constructs the log prolog by invoking the new
'log_prolog' trigger, so that it no longer depends on the version string
and configuration system. Any system that wants to present a message in
the log prolog can define its own trigger, which calls standard log
primitives to print the message.
Split the logging system into a front-end (log.c) that provides the
logging primitives and is independent of the configuration system, and a
set of back-end "outputters" (log_output_console.c, log_output_file.c,
log_output_android.c) that may depend on the configuration system and
are decoupled from the front-end using the 'logoutput' link section.
These log outputters are explicitly linked into executables by the
Makefile rules, but could also be linked in using USE_FEATURE(). The
USE_FEATURE() calls have _not_ been added to servald_features.c, so that
different daemon executables can be built with the same feature set but
different log outputs.
swiftc(1) requires every -D option to be prefixed with -Xcc, which
is not easy to achieve using autoconf.
Now instead of setting configuration macros like HAVE_LSEEK64 on the
command line using -D, they are defined in config.h, which is generated
by ./configure, ignored by Git, and included by all headers and source
files that use any configuration macro.
The dependency on Makefile has been replaced with a dependency on
Makefile.in and config.h, which helps avoid some redundant full
recompiles after running ./configure, because the configure script
does not overwrit config.h if its content does not change.
The quit-on-monitor-client-disconnect test was non-deterministic
depending on load (eg, other concurrently running tests). Under load,
it was likely that the server did not process the "monitor quit" command
before checking for disconnect, so the server did not terminate.
The fix was to make the monitor interface read and process all queued
input from the client before checking for HUP or ERR condition on the
socket. With this fix, the "sleep 1" kludges before and after the echo
"monitor quit" to the console command are no longer needed.
In the process the monitor interface code was modernised: eg, now it
calls read_nonblock() instead of read(2).
Original DEBUG() and DEBUGF() macros renamed to _DEBUG() and _DEBUGF()
New DEBUG() and DEBUGF() macros, first argument is flagname
New DEBUGF2(foo, bar, ...) macro does if(config.debug.foo||config.debug.bar) test
Replace almost all config.debug.xxx references to IF_DEBUG(xxx)
Make .o files in separate subdirectories for servald and library
Factor struct __sourceloc and __WHENCE__ from "log.h" into "whence.h"
Factor sid_t etc from "serval.h" into "serval_types.h"
Factor rhizome_bid_t etc from "rhizome.h" into "rhizome_types.h"
Do not include "serval.h" in library sources
Add log_stderr.c and logMessage.c for stand-alone executables
The recently added cmp_sockaddr() function does not call stat(2) any
more to compare local AF_UNIX socket address paths, so not it is stable
enough to use for ordering sockaddr structs.
New function: real_sockaddr() converts the file path of a local AF_UNIX
file socket using realpath(3). The MDP client uses it on the sender
address of every MDP reply packet it receives to ensure that symlinks in
the instance path do not cause MDP client failures.
Rename recently added socket_setname() function: make_local_sockaddr().
Finish the work started by Daniel in 2012, by using abstract local
AF_UNIX sockets on platforms that support them (Linux, Android).
Fix all sorts of bugs and issues that prevented the existing MDP and
Monitor client and server code from working with abstract socket names.
Handle selection between normal & abstract sockets in a single place.
overlay_mdp.c tried to have both but this seems like a bug so I've removed the second socket (needs tests).
