commit c60f33e229e31ab328ef6b59dab63b264954831c
Author: Alexandre Elias <aelias@google.com>
Date: Fri Jul 10 16:23:09 2020

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 version comparison insdie ActivityResultFragmentVersionDetector is clearly inadequate. The simple length and string comparison end up returning true when they shouldn't

From the lint check:

            val currentVersion = library.substringAfter("androidx.fragment:fragment:")
            if (library != currentVersion && FRAGMENT_VERSION.compareVersions(currentVersion)) {
                locations.forEach { location ->
                    context.report(
                        ISSUE, expression, location,
                        "Upgrade Fragment version to at least $FRAGMENT_VERSION."
                    )
                }
            }

But if you plugin the the current version of "1.3.1", you can see how it yields the wrong result.

val FRAGMENT_VERSION = "1.3.0"
fun String.compareVersions(other: String): Boolean {
    return when {
        length < other.length -> true
        length > other.length -> false
        else -> this < other
    }
}
FRAGMENT_VERSION.compareVersions("1.3.1")
res3: kotlin.Boolean = true

zh...@google.com <zh...@google.com> #5Mar 11, 2021 04:47AM

I'm hitting this bug as well when fragment-ktx is upgraded from 1.3.0 to 1.3.1.

Looking at ActivityResultFragmentVersionDetector, I couldn't really understand the compareVersions() function in it:

        const val FRAGMENT_VERSION = "1.3.0"
...
        if (library.isNotEmpty()) {
            val currentVersion = library.substringAfter("androidx.fragment:fragment:")
            if (library != currentVersion && FRAGMENT_VERSION.compareVersions(currentVersion)) {
                locations.forEach { location ->
                    context.report(
                        ISSUE, expression, location,
                        "Upgrade Fragment version to at least $FRAGMENT_VERSION."
                    )
                }
            }
        }
...

    private fun String.compareVersions(other: String): Boolean {
        return when {
            length < other.length -> true
            length > other.length -> false
            else -> this < other
        }
    }

So say library is androidx.fragment:fragment:1.3.1, currentVersion would be 1.3.1 and the Lint detector reports an issue if "1.3.0".compareVersions("1.3.1") returns true. And since "1.3.0" and "1.3.1" has the same length, it reports an issue if "1.3.0" < "1.3.1", which is true (Playground), and we get a Lint failure here.

I'm confused about how the current compareVersions() implementation is supposed to work for semantic versions, because it doesn't seem to work for a number of scenarios I could think of:

Case	`FRAGMENT_VERSION`	`currentVersion`	`length <=> other.length`	`this < other`	`compareVersions()` (reports Lint error)	Works as expected
Older stable release	`"1.3.0"`	`"1.2.0"`	`length == other.length`	`false`	`false`	`false`
Older unstable release	`"1.3.0"`	`"1.3.0-alpha01"`	`length < other.length`	N/A	`true`	`true`
Exact unstable release (aosp/1564487)	`"1.3.0"`	`"1.3.0-alpha06"`	`length < other.length`	N/A	`true`	`false`
Newer unstable release	`"1.3.0"`	`"1.3.0-beta01"`	`length < other.length`	N/A	`true`	`false`
Exact stable release	`"1.3.0"`	`"1.3.0"`	`length == other.length`	`false`	`false`	`true`
Newer stable release	`"1.3.0"`	`"1.3.1"`	`length == other.length`	`true`	`true`	`false`

zh...@google.com <zh...@google.com> #6Mar 11, 2021 04:56AM

Oh, if the intention here is to simply report an issue for all non-stable versions (which will have a different string length) to avoid pulling in a full semver implementation, I think we just need to flip the comparison in else -> this < other here to fix this for stable versions.

jd...@gmail.com <jd...@gmail.com> #7Mar 11, 2021 05:44AM

Flipping it would work for a quick fix, but the length check may still end up returning incorrect data if the patch version of fragment ever reached 2 digits, 1.3.10.

We still get it with Activity 1.2.2 and Fragment 1.3.2.

Edit for https://issuetracker.google.com/issues/182388985#comment14

The issue is fixed.

I'm sorry for the previous message, the issue was caused by the dependency configuration of our project (some modules had a transitive dependency on previous activity/fragment versions).

lb...@gmail.com <lb...@gmail.com> #17Mar 31, 2021 05:52PM

@15 Is this the final answer? How do you know this one fixed it?

il...@google.com <il...@google.com> #18Mar 31, 2021 11:10PM

Upgrading to Activity 1.2.2 (or Activity 1.3.0-alpha05, which also includes the fix) is the only requirement.

Fragment 1.3.2 includes a dependency on Activity 1.2.2, so upgrading your version of Fragments will also pull in the fix via the transitive dependency.

lb...@gmail.com <lb...@gmail.com> #19Mar 31, 2021 11:34PM

@18 Meaning this is fine:

implementation "androidx.fragment:fragment-ktx:1.3.2"

?

But how do you guys know this fixed the issue?

il...@google.com <il...@google.com> #20Mar 31, 2021 11:37PM

Re comment#34 - then it is likely this is not a false positive - many other libraries (like AppCompat) depend on a very old version of Fragments. This Lint check works even in those cases to tell you that you need to upgrade your Fragment version manually.
