Yes, a developer should not test his own stuff!
  • Group code review turns on circuits in your brain that see errors you ignored before. I call it the audience effect.
  • The dialectic tension between tester and developer is also an important resource. You love it, but he loves to find fault.
You deserve pretty code, so indent, tab align, slip in white space to keep things neat. You get paid back in better review, fewer errors and faster fixes. Every time you use a new line or each item, you help track changes in line oriented CM tools like SCCS and diff.

Log like you expect a midnight call when you are on vacation. After years of debugging with bad logging, I am now a fastidious logger and error checker. From first trial run to last is very short, usually, because my code does not go far off the track but I get a nice message and exit. Frame runs in the same log with header and trailer lines and blank lines. Put exact time stamps on all events. It's frustrating to be fixing errors in the wrong log. Put date-time-elements in file names, especially the log. For daemons that run many days, use syslog or start a new log every day. You can have a standard logging routine that saves the integer time() of tomorrow so I can check time() and close the log when necessary, with an old log trailer and the new log with a header.

DOVEADM-LOG(1)							      Dovecot							    DOVEADM-LOG(1)

NAME
doveadm-log - Locate, test or reopen Dovecot's log files SYNOPSIS
doveadm [-Dv] log errors doveadm [-Dv] log find [directory] doveadm [-Dv] log reopen doveadm [-Dv] log test DESCRIPTION
The doveadm log commands are used to locate and reopen the log files of dovecot(1). It's also possible to test the configured targets of the *log_path settings. OPTIONS
Global doveadm(1) options: -D Enables verbosity and debug messages. -v Enables verbosity, including progress counter. COMMANDS
log errors doveadm log errors The log errors command is used to show the last - up to 1,000 - errors and warnings. If no output is generated, no errors have occurred since the last start. log find doveadm log find [directory] The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages. If dovecot(1) logs its messages through syslogd(8) and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log files. log reopen doveadm log reopen This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings. These settings are configured in /etc/dovecot/conf.d/10-logging.conf. This is for example useful after manually rotating the log files. log test doveadm log test This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files. The used prior- ities are: debug, info, warning, error and fatal. EXAMPLE
This example shows how to locate the log files used by dovecot(1). doveadm log find Looking for log files from /var/log Debug: /var/log/dovecot.debug Info: /var/log/mail.log Warning: /var/log/mail.log Error: /var/log/mail.log Fatal: /var/log/mail.log REPORTING BUGS
