Setting sentry's context

So I recently upgraded to the latest snapshot, and I'm trying to migrate this:

sentry?.captureException(e) {
    setContexts(
        "character", mapOf(
            "name" to character.name,
            "level" to character.level,
            "userId" to character.userId,
            "world" to character.world
        )
    )
    setContexts(
        "guild", mapOf(
            "name" to guild.name, "id" to guild.longId
        )
    )
}

sentry?.captureException(e) {
    setContexts(
        "character", mapOf(
            "name" to character.name,
            "level" to character.level,
            "userId" to character.userId,
            "world" to character.world
        )
    )
    setContexts(
        "guild", mapOf(
            "name" to guild.name, "id" to guild.longId
        )
    )
}

First thing I tried was to replace captureException with captureThrowable. This sentry instance is coming from EventContext in a custom KordEx event.

Solution:

See the announcement I just made - I've added two parameters to the capture functions, which should be sufficient

Using captureThrowable is correct, yes I don't think you need to add the guild context? I'm pretty sure we do that for you ah, no, that's just for things you don't catch anyway, I think probably adding contexts to the sentry context might be an approach? I'm not sure tbh the sentry context objects are meant to be transactional, in that they're tied to the execution of an event handler, command, component, etc so it's more intended for you to add breadcrumbs than directly add context but I should be able to expose that ok, I've extended the API a bit will build and release

Perfect! Thank you!

Either way it is not an event that has a specific guild attached to it, but rather, it finds the relevant guilds where it has to announce something. In this context, I want to log reasons for why an announcement could not be made to a guild. Any way, I guess it is better to set the guild's object in the lambda for that instead 🤔

sentry?.captureThrowable(e,
    mapOf("character" to character.toSentryMap())) {
    this.guild = guild
}

sentry?.captureThrowable(e,
    mapOf("character" to character.toSentryMap())) {
    this.guild = guild
}

gdude•11mo ago

huh? There's no guild propery in that builder

GalarzaaOP•11mo ago

There is, SentryCapture.guild

public abstract class SentryCapture : KordExKoinComponent {
    /** Channel object to automatically populate data from. **/
    public open var channel: Channel? = null

    /** Guild object to automatically populate data from. **/
    public open var guild: Guild? = null

public abstract class SentryCapture : KordExKoinComponent {
    /** Channel object to automatically populate data from. **/
    public open var channel: Channel? = null

    /** Guild object to automatically populate data from. **/
    public open var guild: Guild? = null

gdude•11mo ago

oh yeah, you're right I forgot about that wait but then the API change I made doesn't make sense what is character in this case? the RPG character from before?

GalarzaaOP•11mo ago

Yes

gdude•11mo ago

because it feels to me like it doesn't make sense to only add this context to the Sentry context when an exception happens like it'd make much more sense to have a generic breadcrumb that's like "Loaded character" with the data earlier on beginning to remember why I implemented it the way I did now I should leave more notes in my code yeah, so you'd just do like

GalarzaaOP•11mo ago

To be honest, I'm not exactly sure how breadcrums display in sentry or work. In another component of my project that uses sentry directly, I'm also using context on exceptions, so I can see them attached to the issue like:

gdude•11mo ago

sentry?.breadcrumb {
  message = "Loaded character"
  // Copy data from `character` into `this.data`
}

sentry?.breadcrumb {
  message = "Loaded character"
  // Copy data from `character` into `this.data`
}

I see well, breadcrumb data generally just displays as an object, so maybe being able to add to the primary context makes sense but I don't think it makes sense to only do that at submission time that results in a lot of duplicated code instead, I think it might be better to either use a breadcrumb, or swap to an API that allows you to store extra context at the SentryContext level, and then have that submitted whenever anything is captured that makes the most sense to me, at least this is largely because kordex itself will submit things to sentry like if you run a command and there's an uncaptured exception you probably still want the context on sentry this needs a fair bit more engineering than what I pushed this morning, but does it seem like a better approach to you? in that sense it'd be sentry.context("character", whatever) and then just don't catch the exception (or rethrow it, or handle it yourself and just call the capture function)

GalarzaaOP•11mo ago

That reminds me I did have a command error, but the issue raised on issue had no info about the command that was used. i don't know if it was lost due to the exception happening inside a component's callback 🤔

gdude•11mo ago

that's what happened, yeah

GalarzaaOP•11mo ago

But that was a separate issue, and that was still on 1.6.0, hence why I'm upgrading, so I can test that again and not report an unsupported version 😅

gdude•11mo ago

I couldn't figure out how to handle an optional command/eventhandler coupling with component builders without rewriting half the library so I didn't

GalarzaaOP•11mo ago

I have a lot of those 🙃 , usually confirmation messages for important actions

gdude•11mo ago

the API is too generic to be tied to the parent builders but anyway that's a different problem what do you think of my proposal above

GalarzaaOP•11mo ago

Yeah, I was checking sentry docs to see how that would look and it looks good to me:

GalarzaaOP•11mo ago

How do capturing event and messages work? Specially with free tier quotas? 🤔

gdude•11mo ago

Not sure on the quotas I think the correct attitude to developing with the Sentry extension is probably worth documenting when I eventually get to that

GalarzaaOP•11mo ago

I've only had experience with Sentry on python before but using it on python is like cheating, way too much info available without doing much, it just shows you all the values of variables in the scope right there:

GalarzaaOP•11mo ago

Also not much documentation for kotlin, specially coroutines

gdude•11mo ago

Sentry doesn't actually support Kotlin It's just the Java library I think the JVM is capable of collecting some of that kind of info, but it would be slow probably

GalarzaaOP•11mo ago

There is a Kotlin extension, I was actually having some trouble due to my context being mixed due in coroutines (in another module without kordex), like it would contain the context of a different part of the code. So I had to do some changes for that. Maybe it would be worth looking into it for kordex too: https://docs.sentry.io/platforms/java/enriching-events/scopes/#kotlin-coroutines

Scopes and Hubs

SDKs will typically automatically manage the scopes for you in the framework integrations. Learn what a scope is and how you can use it to your advantage.

gdude•11mo ago

This doesn't look useful for kordex Actual Sentry scopes don't get created until just before they're submitted The global API is avoided entirely Sentry's global API is a horrible anti-pattern

GalarzaaOP•11mo ago

Then maybe I should look into that lol, in my other modules, because what I have on these other modules doesn't seem very good lol Anyway, thanks for the help!

gdude•11mo ago

No worries, I am going to change this API again though so don't get too comfortable I'll do a version bump tho

GalarzaaOP•11mo ago

Yeah, I'm going to stick with breadcrums instead like you suggested, sorry for the confusion

gdude•11mo ago

Alright, no worries

GalarzaaOP•10mo ago

Don't want to open yet another thread on sentry, but I found a small issue on the recent changes to contexts. Seems like contexts have to be objects (or maps): Got this on Sentry:

GalarzaaOP•10mo ago

https://github.com/Kord-Extensions/kord-extensions/commit/a0445169c9bcc01d432a18bca420f6bcba171eb9 Because you are setting extension to be just a string.

Oh, huh, it needs to be an object?

GalarzaaOP•10mo ago

yes

gdude•10mo ago

Thanks for the heads up, I'll look at it tomorrow

GalarzaaOP•7mo ago

Just a bit of a shameless "bump", but I opened a PR related to this a couple of weeks ago: https://github.com/Kord-Extensions/kord-extensions/pull/295
