Mar 23, 2023 08:30PM

Jetpack Compose version: Compose BOM 2023.03.00, Compose Compiler 1.4.4

Jetpack Compose component used: compiler

Android Studio Build: N/A

Kotlin version: 1.8.10

This is a regression first introduced in Compose Compiler 1.4.3, it worked fine in 1.4.2. It may be related to the fixes that Chuck is working on right now, e.g. https://issuetracker.google.com/issues/264467571

Steps to Reproduce or Code Sample to Reproduce:

Minimal repro project at https://github.com/bubenheimer/composeinlinebug

@Composable
fun Screen() = MyDialog { if (false) Box {} }

@Composable
inline fun MyDialog(crossinline content: @Composable () -> Unit) = Dialog({}) { content() }

This looks a little funny only because it's a minimal repro.

Stack trace (if applicable):

commit c60f33e229e31ab328ef6b59dab63b264954831c

Semantics no-op cleanups

Partly in response to lmr's broad code review, I did a pass of
superficial API/implementation cleanup. The main changes are:

- I changed each Boolean SemanticsProperty where false is equivalent to
not being present to take "Unit" instead. This is conceptually
clearer: it avoids questions like "can I cancel out a semantics from a
merged child by setting it to false?" Because "property = Unit" looks
weird, I also changed the style of these to "property()".

- I moved the Semantics id generator closer to where it's used, in
SemanticsModifierCore. I made it internal and an AtomicInt.
(Note that integer ids are heavily used in the Android
AccessibilityNodeInfo APIs so I can't simply remove them entirely.)

- I deleted dead code. Some examples include SemanticsHintOverrides,
a public API not connected to anything, and SemanticsPropertyKey
merge() open method which is never called. (In both cases I have
a different plan in mind for accessibility.)

Fixes: 145951226
Fixes: 145955412
Test: existing tests
Relnote: "Single-value semantics properties now use a calling style.
For example, 'semantics { hidden = true }' is now written as:
'semantics { hidden() }'."

The issue appears to be that, starting in 1.4.3, the composer used in the inlined lambda is the one captured from the parent. This is not the right one when a dialog is being presented as it is the composer for the dialog, not the dialog host.

ch...@google.com <ch...@google.com> #4Mar 23, 2023 10:15PM

The only change between 1.4.2 and 1.4.3 is https://android-review.googlesource.com/#/q/Ie93edb78b8427e56b4bef15b872a919b8bac0664

Handing this to Andrei to look at as this was his change.

ch...@google.com <ch...@google.com> #5Mar 23, 2023 10:20PM

Note to Andrei: After the aosp/2423347, the cross-inline lambda is capturing the $composer parameter from the caller instead of using the $composer parameter passed in to the lambda it was inlined into. This causes changes to be made to the composer that is not currently being used for composition which confused the recomposer.

ch...@google.com <ch...@google.com> #6Mar 24, 2023 05:21PM

This issue affects crossinline lambdas that are inlined into another lambda, as demonstrated by the repro case above, when the composable lambda is executed with a different composer than the function declaring the lambda. A different composer is used when a lambda is invoked in a subcomposition such as a dialog, BoxWithConstraints, and LazyColumn, amoung others.

A crossinline lambda is requred because it is illegal to invoke an non-crossinline lambda in a realized lambda (which is what crossinline allows).

The easiest work-around is to remove inline from the function which avoids the expanding of the lambda in another lambda required for this bug to manifest.

Thank you for the elaboration! The non-inline workaround is what I've been using since this code broke.

Use composer of the correct scope when realizing groups

Updates function body transform to use composer parameter from target scope to realize groups. The realize call can happen outside of such scope and composer parameter is not guaranteed to be the same between scope where groups are being realize and current scope at the time of the call.
