v2.6.2 - Device-accurate Collections, Numbers and Task Fan-out

This release is a round of device-verified accuracy and performance fixes, each checked against a real Roku with a probe app now committed under test/simulator/probes/. Collections can be indexed with any numeric type (Double, LongInteger, boxed numbers) without the whole container being copied on each read, writes with a negative or out-of-capacity index are ignored with the device's warning, and built-in methods read their Integer arguments like the device (a LongInteger index no longer loses its low 32 bits). What type() reports for a container member now depends on how it was stored, as on the device, and storing a value no longer changes the type() of the variable it came from. Numbers print nan/-nan/inf/-inf/-0 like the device, and Val() reads the longest numeric prefix like C's strtod/strtol. roByteArray for each no longer skips the first byte, and CreateObject("roRegex", ...) with a pattern JavaScript can't compile prints the device's error and returns invalid instead of crashing the app. In the SceneGraph extension, render→Task fan-out is now batched — fixing Rooibos code-coverage runs that hung or ran out of memory — and a Task's XML onChange runs only on the render thread, as on the device. Boxed values are also lighter, since components now create their method maps on first use. Read the full release notes below for more details.

Release Changes

Core Engine

• (brs) Fixed storing a value in an array or AA changing the original variable's type() by @quan7794 in #1259
• (brs) Matched the device's type() for container members by how they are stored, and fixed roXMLList.AddHead appending at the tail by @lvcabral in #1265
• (brs) Components now create their method and interface maps on first use, so boxed values take about a third of the memory by @lvcabral in #1266
• (brs) Fixed roByteArray indexed reads copying the whole array by @jay23606 in #1267
• (brs) Collections can be indexed by any numeric type without copying, built-in methods read Integer arguments like the device, and nan/inf/-0 formatting and Val() parsing now match the device by @lvcabral in #1270
• (brs) Fixed roByteArray for each skipping the first byte, and Next() past the end now returns invalid by @rahul05ranjan in #1273
• (brs) Fixed roRegex creation crashing the app on PCRE-only patterns: (?-)/(?) are accepted, and an invalid pattern returns invalid as on the device by @rahul05ranjan in #1274
• (node) Fixed a Task worker's first print being dropped on a slow host, by starting the output drain only once the worker is running by @lvcabral in #1269

SceneGraph Extension (brs-scenegraph release v0.6.2)

• (rsg) Batched render→Task fan-out and stopped leaking port events for a running Task, fixing Rooibos code-coverage runs hanging or running out of memory by @markwpearce in #1264
• (rsg) A Task's XML onChange now runs only on the render thread, and its message ports are kept out of render's m by @lvcabral in #1268

Chores, Build and Dependencies

• Enabled ESLint no-unused-vars to flag unused imports and locals before SonarCloud does by @lvcabral in #1268
• Fixed the roAppManager getUpTime test flaking on slow runners by @lvcabral in #1278
• build(deps): bump compression from 1.8.1 to 1.8.2 by @dependabot in #1244
• build(deps): bump shell-quote from 1.10.0 to 1.12.0 by @dependabot in #1245
• build(deps-dev): bump brace-expansion from 5.0.9 to 5.0.12 by @dependabot in #1246
• build(deps): bump proxy-addr from 2.0.7 to 2.0.8 by @dependabot in #1247
• build(deps-dev): bump source-map-js from 1.2.1 to 1.2.2 by @dependabot in #1248
