05:35:26NeXeNhrmm, i've been using this idiom to manage scope for a library i'm building. i put it in a try with resources statement and i was doing a simple try (Scope s = Scopes.get(ScopeType.WHATEVER)) { } to get scoped blocks that auto close (implementing auto closable)
05:36:24NeXeNwell turns out my IDE i guess shows a warning, since the local variable s isn't used anywhere.....you know it's defined in the try statement and never used because i don't need to, it just initiates a scope and is auto closable to make it clean so there's no leakage or residual scope bugs.
05:37:42NeXeNso i'm curious, if i replace it with var _ = Scopes.get() will the _ be ignored by the ide's "problems". i'm using a vsclone and you know that standard java plugin from redhat
05:38:23NeXeNjreicher: i'm wondering what harm it would be to do that. i guess none since i don't often fail to use something i defined in local scope
05:45:21deeboif your min version is a java version that supports _, it should be fine, we have that all over our code to specifically get around the unused variable stuff
06:25:51NeXeNyeah i don't have local unused vars ever hardly, but this time i chose it as a pattern to ease the headache of edge cases. allowing it to autoclose makes it so much easier and more robust
06:46:18deebofor that specific use case, it might even make more sens to do Scopes.get(...).inScope((_) -> ...);, or without the param if it's never needed
06:46:32* pr070cal joined #java
06:46:36deeboweird that "anonymous" try-with-resource is not supported though
06:47:15deeboi sort of remember using it, but looking at the code, it's always with a resource, even if not referenced, like http calls etc

08:49:42jreicherFWIW I would also use _ in that situation, but I haven't had to do it in practice.

10:14:33NeXeNyup, changing everything to var _ = solves the issue. just have to state it clearly in the docs. maybe someone will come up with a good fix like a config value but whatever, works for now
10:16:37ParaIs it VS Code complaining or actual javac?

11:22:49jreicherNeXeN: why do you not consider var _ a fix? Not only does it not generate a warning but it also states the intent of the code. It probably doesn't even need documentation.

12:23:09Opticthis morning's battle: figure out why the scope claim in my jwt is missing when it gets to spring's JwtGrantedAuthoritiesConverter

13:53:41Opticomg figured it it out, it's because I wasn't REQUESTING the scopes in intellij httpclient. :P 100% PEBKAC
13:54:48hassoonintellij's httpclient ?
13:55:07dreamrealhappens a lot and has happened to all of us, probably. To the ones it has NOT happened to: well, you just ain't tried yet or you're lying about it :D
13:55:54Optichasson i'm using it for debugging... the actual application requests the scopes properly but my debug setup did not
13:56:43* hwpplayer1 joined #java
13:57:59hassooni see
14:00:08Opticif you use the IDE i recommend checking out the feature, it's handy. saves jumping out to something like postman or bruno
14:00:22hassooncool; +1
14:01:51ParaIntelliJ's built-in http client is pretty nifty for API testing as well.

15:56:32gas51627Hi all, should I try to make my services singletons, that is, existing for the duration of the running app or is it fine to create a service object each time I get a request?
15:57:25gas51627In other words, what can be a singleton, should it be a singleton?
16:03:06nimajesingleton means there can be only one object of that class and you should avoid that if possible, but your app holding onto one instance of some class and use that for all requests can be a good idea in some cases, that depends on your use case and other tradeoffs
16:18:40dreamrealgas51627: it depends on what they do and what they need
16:18:44dreamrealand how you're building them
16:18:55dreamrealthere's no answer that fits in a general sense
