Re: How to log pharo output to stdio safely?

Hi Stef - I was aware of that class - but a good reminder to re-read it for any extra info, but I don't see anything in particular mentioned about how data is flushed - and I think this is one of those black arts from in the field. It looks like stdio uses an Stdiostream - and I did note an interesting comment in #flush which mention #sync and "When writing, this syncs any written/flushed data still in the kernel file system buffers to disk. This should generally be used after #flush, but on Windows they do the same thing." I've never heard of #sync before - and I wonder if the trick to getting output without the cr is to do a "flush; sync" operation? But even then, I am thinking that a server based logging tool is going to need a cr on a log line to know how to interpret it and parse it into syslog format, so perhaps I can't escape moving the a trailing cr policy - and just try to make sure most of my logging adopts that standard (and just accept the odd corruption when other libraries write out crTrace?). I'm just curious how others handle this kind of stuff in the wild - maybe I should ask on a Seaside list as they are more likely to delve into this (or maybe the Gemstone guys). Its a world you don't normally pay attention to until you try and run something on a server and want to use the modern tools available in that world.

How to log pharo output to stdio safely?

by Tim Mackinnon

Hi - I've been messing around with deploying a hobby pharo app to the web.. which has become a lot simpler over the years, although the tech keeps changing and you have to relearn things. Anyway, I have my image in one of the wonderful BA Docker containers, and it runs well - and the host I'm using will show the logs for you, so you can figure out what is going on... well that is if your logs come out properly (and of course, if it gets really hairy then you can get a VNC session onto the image and figure stuff out) So logs are handy, and pharo these days has a nice headless mode that redirects the Transcript to stdout - and there are also a few decent logging frameworks as well. But as most things go to the Transcript, and that goes to stdout - it should be good. HOWEVER - flushing is the killer, as if things happen and the last thing goes wrong, but the output isn't flushed, then you aren't going to see it. So my question is how to properly flush? And I'm sure I've read something about this before, but I can't find it. >From memory, you often need to have a Transcript cr. to flush your last line. BUT, most things in the image seem to use "self crTrace:" these days, which is a cr to ensure the previous msg is separated from what you want to write, and then you write your line out. However, as there is now cr - you might not see it. So I tried changing my stuff to use "self traceCr:" (which is in the image), and that still didn't seem to work - the last failing line wasn't being output. Worse still, its confusing, as many things in the image are using crTrace: and so you get intermingled messages, which are hard to decipher. So I tried: Transcript cr; show: msg; flush But that didn't seem to work (which I don't understand) Eventually I did: Transcript show: msg; cr; flush And this seems to ensure things do reliably get outputted - but I'm wondering if anyone can shed light on this areas? Ideally I want to use: Transcript cr'; show: msg; flush As this plays much better with everything that is in the image - but is there some way to do this? And indeed, will log tools the Bettersatack or papertail play ball with output like this (as I guess they operate on complete lines to interpret log levels etc), Anyway - I'm curious if anyone else has done work in this area to shed light?

Sadly that service didn't survive... but there are quite a few like it now, and so I'm trying Render.com - which is similar, but the twist is you need to store a Docker image in a registry somewhere (I use gitlab from my CI pipeline), and then it will retrieve it and run it for you (for either free in 40 minute chunks, or for $7/m - which is pretty good, and possibly bit simpler than Digital Ocean).
