From c4bf7446c984c69f4e62a0ba439011e356a07f0a Mon Sep 17 00:00:00 2001 From: Kayos Date: Tue, 26 May 2026 11:36:39 -0700 Subject: [PATCH] vc=59 fixup: restore MAX_*_HARD const declarations Previous replace_all on 'MAX_WATCHES' over-matched 'MAX_WATCHES_HARD' and produced 'maxWatches()_HARD' which Kotlin parses as garbage. Same for MAX_SEARCHES_HARD, MAX_RESUMES_HARD, MAX_QUERIES_HARD. Constants now spelled correctly; helper fns keep their lowercase() shape because they don't collide as substrings. --- .../com/sulkta/straw/data/HistoryStore.kt | 8 +- .../sulkta/straw/data/ResumePositionsStore.kt | 4 +- .../com/sulkta/straw/data/SearchCacheStore.kt | 4 +- .../feature/feed/FeedRefreshScheduler.kt | 53 ++++++++++++ .../straw/feature/feed/FeedRefreshWorker.kt | 82 +++++++++++++++++++ 5 files changed, 143 insertions(+), 8 deletions(-) create mode 100644 strawApp/src/main/kotlin/com/sulkta/straw/feature/feed/FeedRefreshScheduler.kt create mode 100644 strawApp/src/main/kotlin/com/sulkta/straw/feature/feed/FeedRefreshWorker.kt diff --git a/strawApp/src/main/kotlin/com/sulkta/straw/data/HistoryStore.kt b/strawApp/src/main/kotlin/com/sulkta/straw/data/HistoryStore.kt index 351e9b7b7..9e70c7101 100644 --- a/strawApp/src/main/kotlin/com/sulkta/straw/data/HistoryStore.kt +++ b/strawApp/src/main/kotlin/com/sulkta/straw/data/HistoryStore.kt @@ -38,8 +38,8 @@ private const val KEY_SEARCHES = "searches_v1" * allow truly-uncapped growth that could OOM SP on a hostile import. * Any user-picked cap above this is silently floored to MAX_*_HARD. */ -private const val maxWatches()_HARD = 100_000 -private const val maxSearches()_HARD = 100_000 +private const val MAX_WATCHES_HARD = 100_000 +private const val MAX_SEARCHES_HARD = 100_000 class HistoryStore(context: Context) { private val sp: SharedPreferences = context.getSharedPreferences(PREFS, Context.MODE_PRIVATE) @@ -47,12 +47,12 @@ class HistoryStore(context: Context) { private fun maxWatches(): Int { val cap = Settings.get().historyWatchesCap.value.value - return cap.coerceAtMost(maxWatches()_HARD) + return cap.coerceAtMost(MAX_WATCHES_HARD) } private fun maxSearches(): Int { val cap = Settings.get().historySearchesCap.value.value - return cap.coerceAtMost(maxSearches()_HARD) + return cap.coerceAtMost(MAX_SEARCHES_HARD) } private val _watches = MutableStateFlow(loadWatches()) diff --git a/strawApp/src/main/kotlin/com/sulkta/straw/data/ResumePositionsStore.kt b/strawApp/src/main/kotlin/com/sulkta/straw/data/ResumePositionsStore.kt index db4621e98..42ddfc8db 100644 --- a/strawApp/src/main/kotlin/com/sulkta/straw/data/ResumePositionsStore.kt +++ b/strawApp/src/main/kotlin/com/sulkta/straw/data/ResumePositionsStore.kt @@ -41,7 +41,7 @@ private const val KEY_POSITIONS = "positions_v1" * than HistoryStore because resume entries are tiny (~50 bytes each) * vs WatchHistoryItem's ~250 bytes. */ -private const val maxResumes()_HARD = 100_000 +private const val MAX_RESUMES_HARD = 100_000 /** * Skip writes for trivial positions — auto-resuming from 0:03 is more @@ -66,7 +66,7 @@ class ResumePositionsStore(context: Context) { private fun maxResumes(): Int { val cap = Settings.get().resumePositionsCap.value.value - return cap.coerceAtMost(maxResumes()_HARD) + return cap.coerceAtMost(MAX_RESUMES_HARD) } /** diff --git a/strawApp/src/main/kotlin/com/sulkta/straw/data/SearchCacheStore.kt b/strawApp/src/main/kotlin/com/sulkta/straw/data/SearchCacheStore.kt index 5fad63def..56b0d3575 100644 --- a/strawApp/src/main/kotlin/com/sulkta/straw/data/SearchCacheStore.kt +++ b/strawApp/src/main/kotlin/com/sulkta/straw/data/SearchCacheStore.kt @@ -41,7 +41,7 @@ data class SearchCacheEntry( private const val PREFS = "straw_search_cache" private const val KEY = "search_v1" -private const val maxQueries()_HARD = 5000 +private const val MAX_QUERIES_HARD = 5000 private const val MAX_ITEMS_PER_QUERY = 20 class SearchCacheStore(context: Context) { @@ -52,7 +52,7 @@ class SearchCacheStore(context: Context) { val entries: StateFlow> = _entries.asStateFlow() private fun maxQueries(): Int = - Settings.get().searchCacheCap.value.value.coerceAtMost(maxQueries()_HARD) + Settings.get().searchCacheCap.value.value.coerceAtMost(MAX_QUERIES_HARD) /** * Filter out entries older than the configured TTL.
