OS logging integrated with `trace` for iOS #1140

elijah-semyonov · 2024-02-26T13:29:56Z

Proposed Changes

Integrate iOS logging with traces API in ui:util modules.
Additional traces in ui in skikoMain source set.

Testing

Test: N/A

API Change

API added to iOS source set

// androidx.compose.ui.util
@ExperimentalComposeUiApi
fun enableTraceOSLog()

…into es/ios-traces

Why do you need multiple copies for each linux/win arch? It should be just one like nonIosNativeMain or just linuxMain. Additional gradle setup is required of course.

Will fix it

+@ExperimentalComposeApi
+fun enableTraceOSLog() {
+    if (traceImpl == null) {
+        traceImpl = CMPOSLogger(categoryName = "androidx.compose.runtime")


It seems it should work on all Apple platforms - macOS, tvOS, watchOS

No, this class is implemented in UIKitUtils framework, which is built for iOS now.

The same - you should combine js and wasmJs into one file/sourceset - webMain

Let's add trace inside postponeInvalidation and pass tag as parameter

Added trace, but didn't get what you mean under pass tag as a parameter, can you elaborate?

It's called from multiple places. Let's add label for trace in parameters of postponeInvalidation?

You're adding unconditional mutex lock in many critical places. It will probably impact performance

I doubt it, it's only around 20 calls per frame and critical section is very short and not congested due to almost all current calls begin on the same thread. Moreover, this logic is performed only if logging was enabled in the first place. It's not supposed to be used in production env.

MatkovIvan

Aside from unconditional adding mutexes, LGTM.

Should be reviewed by someone else too

Other than "runtime" depending on "ui" - looks good to me
