Setting stdin as input will wait for the next keyboard input. Typing an empty line will end the stdin scanner and start parsing the entries.
go test ./...--input= : Choose input to read between standard input stdin or file filename (default stdin)
--output= : Choose output to write between standard output stdout or file filename (default stdout)
./quickstart --input=large-log.txt --output=large-quick-traces.txt--stats=true : Print to standard error additional statistics and log messages (default false)
--help : Print use instructions
- Pending entries management
- One idea would be to store in memory the pending entries, and try every second or so to find their parents in a separate goroutine.
- Upon trigger of that goroutine, it could compare the timestamp of that entry with the current timestamp (which is already stored in a global variable of the quicktrace package), and add make it an orphan in case of expiration. The expiration could be parametrically defined via command line flags
