Story about an obscure bug: https://twitter.com/mmalex/status/...
"We had a ‘fun’ one on LittleBigPlanet 1: 2 weeks to gold, a Japanese QA tester started reliably crashing the game by leaving it on over night. We could not repro. Like you, days of confirmation of identical environment, os, hardware, etc; each attempt took over 24h, plus time differences, and still no repro.
"Eventually we realised they had an eye toy plugged in, and set to record audio (that took 2 days of iterating) still no joy.
"Finally we noticed the crash was always around 4am. Why? What happened only in Japan at 4am? We begged to find out.
"Eventually the answer came: cleaners arrived. They were more thorough than our cleaners! One hour of vacuuming near the eye toy- white noise- caused the in game chat audio compression to leak a few bytes of memory (only with white noise). Long enough? Crash.
"Our final repro: radios tuned to noise, turned up, and we could reliably crash the game. Fix took 5 minutes after that. Oh, gamedev...."5 -
Took me 6+ full days.
The feature does not work. Repro is unknown, so only prod is experiencing the issue.. Which rules out the debugger option. Sometimes there's an entry seen in logs: "java.lang.StringIndexOutOfBoundsException". Nothing more - just that. No stack, no class, no nothing. Is it my code that's buggy? Is it some config? Integration? Unexpected response...? A bug in a lib? Is dimm faulty ir maybe server's shared libs are off?
Turns out I used a closing parentheses instead a closing curly bracket in an error message that's supposed to be interpolated...
String message = "{some-business-rule-related-error-message-key)";
took me 6+ full days... But I found it. Took the rest of that Friday off to walk in a park and enjoy my life :)9 -

I would post it as a joke if it were one :) Turns out It's a very real bug!

4 hours of estimation for a bug which won't repro
Fucking hate these testers (Floyidian bhai tu nai)14 -
A couple of years ago I was working on a fairly large system with a complex (by necessity) access control architecture.
As is usually the case with those projects, it's awkward for developers to repro bugs that have to do with a user's accesses in production when we are not allowed to replicate production data in test, let alone locally.
We had a bug where I ended up making myself a new row in the production database for a thing I could have access to without affecting real data to repro it safely. I identified the bug so I could repro it in dev/test and removed the row and ensured everything worked normally, whew scary.
Have you ever walked into the office one day, and everyone is hunched over in a semicircle around one person's workstation, before one turns around to look at you and says - after a pause - "... ltlian?.."
Turns out I had basically "poisoned the well" with my dummy entity in a way where production now threw 500 for everyone BUT me who had transitive access to this post-non-entity. Due to the scope of the system, it had taken about a day for this to gradually propagate in terms of caching and eventual consistencies; new entities coming in was expected, but not that they disappear.
Luckily I had a decent track record for this to be a one-off. I sometimes think about how I would explain testing in prod and making it faceplant before going home for the day, other than "I assumed it would be fine". I would fire me.3 -
New twist on an old favorite.
Background:
- TeamA provides a service internal to the company.
- That service is made accessible to a cloud environment, also has a requirement to be made available to machines on the local network so you can develop against it.
- Company is too cheap/stupid to get a s2s vpn to their cloud provider.
- Company also only hosts production in the cloud, so all other dev is done locally, or on production non-similar infra, local dev is podman.
- They accomplish service connectivity by use of an inordinately complicated edge gateway/router/firewall/message translator/ouija board/julienne fry maker, also controlled by said service team.
Scenario:
Me: "Hey, we're cool with signing requests using an x509 cert. That said, doing so requires different code than connecting to an unsecured endpoint. Please make this service accessible to developer machines and lower environments on the internal network so we can, you know, develop."
TeamA: "The service should be accessible to [cloud ip range]"
Me: "Yes, that's a production range. We need to be able to test the signing code without testing in production"
TeamA: "Can you mock the data?"
Me: "The code we are testing is relating to auth, not business logic"
TeamA: "What are you trying to do?"
Me: "We are trying to test the code that uses the x509 you provide to connect to the service"
TeamA: "Can you deploy to the cloud"
Me: "Again, no, the cloud is only production per policy, all lower environments are in the local data center"
TeamA: "can you try connecting to the gateway?"
Me: "Yes, we have, it's not accessible, it only has public DNS, and only allows [cloud ip range]"
TeamA: "it work when we try it"
Me: "Can you please supply repro steps so we can adjust our process"
TeamA: "Yes, log into the gateway and try issuing the call from there"
Me: (╯°□°)╯︵ ┻━┻
tl;dr: Works on my server -
Open source is poison, hoax and source of much troubles.
Even as I love OSS, and I use it a lot, when things go south, they go south terribly.
There was "security" updates in one OSS program I have been using, that accidentally prevented use cases which specifically affected me. I raised bug report, made issue and gave small repro for it.
One of the core developers acknowledges that yes, this is problem, and could be handled with few added options, which users of similar use case could use to keep things working. He then tags issue "needs help" and disappears.
After I have waited some time, I ask help how I could fix it myself, like how to setup proper dev environment for that tool. Asked it in their forums few days later, as issue didn't get any response. Then asked help in their slack, as forums didn't get any help.
Figured out how to get dev environment up, fix done (~4 lines changed, adding simple check for option enabled or not) and figured out how to test that this works.
I create pull request to project, checking their CONTRIBUTING and following instructions there. Then I wait. I wait two weeks, and then one of the core develors goes to add label "needs response from maintainer". That is now almost two weeks ago...
So, bug that appeared in October, and issue that was created October 8th, is still not fixed, even as there is fix in PR for 28 days this far.
And what really ticks me off? People who make statements like: "it is OSS, have you thought of contributing and fixing things yourself?" when we run into problems with open source software.
Making fix yourself ain't biggest problem... but getting it actually applied seems to be biggest roadblock. This kind of experiences doesn't really encourage me to spend time fixing bugs in OSS, time is often better spend changing to different tool, or making changes in my own workflow or going around problem some kludge way.
I try to get business starting, and based on OSS tools. But my decision is staggering, as I had also made decision to contribute back to OSS... but first experiences ain't that encouraging.
Currently, OSS feels like cancer.17 -
Why would you shame someone for a no repro when the page was clearly removed AFTER I raised the bug? Obviously if the page wasn't there before, I couldn't have reported on it!!!

Is it sad that I look forward to the weekend so that I can actually write some code rather than:
- Helping clients that can’t / won’t read docs
- Explaining to test colleagues that we need repro steps and can’t fix a bug based on “I was doing something and it crashed”
- Writing any regular expressions for another dev where it’s more complicated than ^[A-Z0-9]*$
- Wading through legacy VBA that’s littered with GoTo, global variables (even i, j and k for loops are fucking global!) and all the other fucking lazy shortcuts that save you 10 seconds at dev time and cost you (which ends up meaning me) hours in subsequent debugging.
I love writing code, and I think I’m pretty good at it, so can I please just get on with it?
Fellow ranters, please tell me I’m not alone in this. -
When the good programer in you tries hard to repro a NPE but ends up adding a bunch of 'null' checks 😔4
-
you know what is the most confusing shit, is that,
> you know the bug
> you know how to solve it
> you know repro it
> bug doesn't repro
> sad life
After trying to repro the bug 50 times I'm sleeping, I mean this need to clear cache only and it should work
