james-willis opened a new issue, #3137:
URL: https://github.com/apache/sedona/issues/3137
Sedona's `RS_MapAlgebra` is backed by jt-jiffle 1.1.24 (jai-ext). Seven
releases have shipped since. The bump brings three things that matter to Sedona:
1. **Loop iteration guard (1.1.31)** — on 1.1.24, a Jiffle script with a
runaway loop (`while (x >= 0) { x = x + 1; }`) hangs the Spark executor
indefinitely. 1.1.31 generates a per-pixel iteration guard (default 200,
configurable/disable-able via the `it.geosolutions.jaiext.jiffle.maxIterations`
system property), so such scripts fail fast instead.
2. **New math functions (1.1.28)** — notably `atan2`, previously missing
from the script language.
3. **Janino 3.1.12** (from 3.0.8 upstream) — aligned with the version Sedona
already shades for Spark compatibility.
The antlr upgrade attempted upstream was reverted (stays 4.7.1), so Sedona's
shading configuration is unaffected.
**Compatibility note:** the new default 200-iterations-per-pixel cap can
affect user scripts with legitimately heavy per-pixel loops; the escape hatch
is the system property above (negative disables). Worth a release-note and docs
mention.
