Valid. You need to know if it’s a sometimes bug or an always bug.
The truly terrifying outcome is that it works after changing nothing. Sometimes bugs are the most fun to squash.
naeapWe seemingly have a different opinion, what we regard as ‘fun’ ;-)
Stuff that can’t be reproduced and “only” comes up because of some timing issue/race condition is often the most shit to hunt for
I’m currently in such an adventure - and I thought I had it…but the statistics show, that it only got better, but didn’t catch all of the occurrences…
Stuff that can’t be reproduced and “only” comes up because of some timing issue/race condition is often the most shit to hunt for
Ah, but if you can’t reproduce it, you can just put in an entry of ‘could not reproduce’ and close the bug report. Case closed. Go home and enjoy a nice beverage.
Happy debugging if it works on the second try… 😬
Best things are, when you throw in some debug output and that changes the timings just as much to not make the bug happen anymore
I’ve lost more hair to that, than my age…
Well, better than the other way around:
Code works perfectly on your test device but breaks down when deployed to field devices with slightly different timing characteristics or whatever.
Bonus points if it only occurs every few weeks, preferably at night shift and crashes a whole production line… 🫣
(Incident totally fictitious, definitely no people out of this thread involved, just move on, really nothing to see here!)
True that…
Happens too fucking often as well
I’m currently hunting a bug that happens like every 1000 iteration of the thing happening.
Like, I’m telling the hardware to do something and it works pretty much all the time, but over the day, the errors add up
I have no clue why it happens, but can’t really turn up the debug logs that much, because with so many things happening, I’d produce like a shitload of data.
But I can’t really narrow it down otherwise
And it seems we’re in the same kind of shit business ;-)
Real time processes and automation, with customers having problems at night shift, because the maintenance guys during that shift are usually not as good - or it’s just bad luck
At one of my last business trips I was already at the airport on my happily way home, when I’ve got call.
Needed to get my luggage back, new rental car and get a place at the hotel.
Just to discover, that after 15 years the hardware acted up in a way it never did before.
At least I could now include a warning message, if this weird situation ever happens again, but that was a tough one to swallow…
AstroLightzVery true, especially when working with recursion. (Debugging recursion sucks)
SkullgridOr the code you are working on is calling a system that is currently unreliable which you cannot be responsible for.
Fuck test automation, it’s a fucking trap get out of it as soon as you can
EDIT : that is to say, test automation as in automation that a tester does, instead of unit tests. If you have started a career as a software tester , get out ASAP.
Darkassassin07The first time, I just saw it’s not working; the second time, I was paying attention to the details to see what specific parts aren’t working and clues as to how/why.

BonjeDue to the non zero ammount of times this happened to me… this is like pressing ctrl+c multiple times to make sure you copied the thing. And then pressing shift+ctrl+c cause you aren’t sure if that works in this terminal emulator.
ChaisWell yes, the trick is to attach the debugger for the second run.
….and because it slows down the execution a bit and this avoids the race condition that triggers the bug, it now runs flawlessly.

xkcd 242 obviously
I feel called out. I’m not sure which way I’d go.
Get somebody else to pull it.
For science.
Me playing point and click games
But sometimes it works, or throws a different error …
And a different error means progress!
A different error each time?
When it does a different crazy thing every time and you have no idea why, it means you’re a genius and have created life.
Or you’re coding in C.
Actually tru. Damn preprocessors.
you have to check if you are dealing with a bug or with a ghost
You make a change. It doesn’t fix it.
You change it back. The code now works.
the real fix was the journey, the destination never mattered
The code now
worksbreaks in a new way.The usual for me is that I flip back over to my editor and hit ctrl+save, cause heaven forbid I ever remember to do that before running.
I have no regrets from setting my editor to save-on-blur
The first one is to warm up the engine. Like getting your car ignition to kick over in the winter
and sometimes that’s exactly what’s needed. Services wake up, connections get established and then when you try again things are up and it works.
Trying to debug race conditions be like
Yuuup… Debugging concurrent code is a bitch.
Code doesn’t work; don’t know why.
Code works; don’t know why.
Cargo Cult Programming is bad.
You know, youve gotta give your computer some warmup.
The error message goes stale when it’s been sitting for a while. I need to see a fresh one.
You jest but “wait and retry” is such a powerful tool in my DevOps toolbox. First thing I tell junior engineers when they run across anything weird
Honestly, in DevOpS, when you’re running stuff in a GitHub Action/Azure DevOps Pipeline/Jenkins, yeah… sometimes a run will fail for no obvious reason.
And then work the next time (and the next 100+ times after that) when you haven’t changed a damn thing.
“Maybe if we ignore the problem, it will go away”
Running the code again is fast and requires no thinking. Finding the problem is slow and requires a lot of thinking.
It’s worth looking under the light-post in case your keys somehow rolled there. Just not for long.
The absolute worst thing that can happen is if it suddenly starts working without doing anything
Sweet, push to production.
Not sure which is worse. When you know you changed nothing and it inexplicably starts|stops working compared to yesterday
Far worse, and this applies to more than programming. If something is broken, I want it to be consistent. Don’t fix yourself, or sort of work but have a different effect. Break, and give me something to figure out, damn it.
This would be more mockable if it didn’t often WORK.
gotta rule out cosimc rays flipping a bit or two
Computer needs practice to get program right.
Just making sure that the write buffer was flushed on time or something.
I started coding professionally using Visual Basic (3!). Everybody made fun of VB’s
On Error Resume Next“solution” to error handling, which basically said if something goes wrong just move on to the next line of code. But apparently nobody knew aboutOn Error Resume, which basically said if something goes wrong just execute the offending line again. This would of course manifest itself as a locked app and usually a rapidly-expanding memory footprint until the computer crashed. Basically the automated version of this meme.BTW just to defend VB a little bit, you didn’t actually have to use
On Error Resume Next, you could doOn Error Goto errorHandlerand then put theerrorHandlerlabel at the bottom of your routine (after anExit Sub) and do actual structured error handling. Not that anybody in the VB world ever actually did this.And run it with the debugger.
sometimes it needs to warm up.. or cool down
When your
Makefileis so fucked up that you have to run it multiple times to get everything to build and link properly.… try it now.
demonsahem. data-races.This is just how you use Visual Studio
Because you’re Good developer
Or the code you are working on is calling a system that is currently unreliable which you cannot be responsible for.
Fuck test automation, it’s a fucking trap get out of it as soon as you can
lol.
Meanwhile, the org I work at has no test automation, so things that should be trivial require hours of tedious, error-prone, manual testing. Also they break stuff and don’t find out until after it’s merged.
This post has appeared in multiple places. It’s useful , but it ruins the development career potential of people that stick with it, because any subsequent job application just sees “TESTER” and not “DEVELOPER” and bars you from changing specialization.
I’ve known several people who moved from QA and testing to developer roles, but usually as an internal transfer.
Most recruiters and management don’t know shit about fuck when it comes to technical details, so it’s not surprising a lot of them think “Oh the guy who knows how software works and how to handle edge cases? No, we don’t want him”
yeah. My current company botched mine.
Most applications aren’t written to compile deterministically so there is always a chance.
Compile? Is that true? Pretty sure compilers are generally deterministic in their output.
