|Summary||0018197: EventLog always uses "dummy" implementation, not OS-specific, which breaks e.g. daemon under Unix|
|Description||In trunk, src/dummy directory is inside the includedir in packages/fcl-extra/Makefile.fpc. Unfortunately, this means that files inside dummy/ dir override (are picked up first, at least on Linux) the "real" implementations inside unix/.|
This means that TEventLog cannot really write to syslog: LogType = ltSystem (the default) is handled by the src/dummy/eventlog.inc implementation, which simply fallbacks to writing xxx.log file instead of opening the syslog.
Testcase: try tstelcmd demo (after applying 0018196 to make it compileable again). It should write to syslog, but instead it creates tstelcmd.log file. By adding debug writeln inside fcl-base/src/dummy/eventlog.inc (e.g. at the beginning of TEventLog.ActivateSystemLog) we can confirm that indeed the "dummy" implementation is used, instead of the Unix one.
Removing src/dummy dir from includedir in fcl-base/Makefile.fpc (and regenerating with fpcmake) makes things working. This compiles good eventlog unit, which in turn means that compiled tstelcmd works correctly.
This bug also makes the daemon demo broken under Linux with my tests. I didn't dig in too deep, but the daemonization (running ./daemon --run -b) simply fails, i.e. parent exits but the child process (which should become a daemon) dies too. Probably because the child tries to write a file that is already closed by the parent process? After removing src/dummy, the daemon started working (and logging to syslog) perfectly.
Note that the same error is repeated inside packages/fcl-extra/Makefile.fpc. Fortunately, packages/fcl-extra/src/dummy is empty for now, so it didn't cause any actual problems yet.
