Oh, sorry. I was wrongly thinking that the Heikki's recently changes to nls.mk fixed that.... Fixed. Thanks! Regards, -- Fujii Masao

Not a fan of this approach, because now this function knows that pg_log(PG_PROGRESS) is equivalent to printf(). This abstraction is a bit leaky, isn't it ...

Now pg_log() calls printf() and fflush(stdout). So '\r' is printed after fflush. It's a bit strange. Maybe we can just replace pg_log() with printf() here. Another question is; should we output the progress report to stderr rather than stdout? I thought this because I found that pg_basebackup reports the progress to stderr. Regards, -- Fujii Masao

A better solution from a modularity point of view would be to add a new function, pg_progress() for this. It would print the line with pg_log() and then print the \r to the end. Then the caller wouldn't need to know whether the progress messages are going to stdout, stderr, or somewhere else entirely. > Another question is; should we output the progress report to stderr rather > than stdout? I thought this because I found that pg_basebackup reports > the progress to stderr. Yeah, probably. We should go through all the output and figure out where each kind of message needs to do. Should follow the principle Alvaro laid out (http://www.postgresql.org/message-id/20150407205320.GN4369@alvh.no-ip.org), and also make sure it's consistent with pg_basebackup and other tools. Michael's patch changed some of the logging but we should take a more holistic look at the situation. And add a comment somewhere explaining the principle. - Heikki

And add a comment somewhere explaining the > principle. Isn't what we are looking for here a common set of frontend-only APIs, let's say as src/common/logging.c? All the tools we have could use it without knowing if they output on stdout and stderr. -- Michael
