…aho-mqtt-cpp The Nix environment provides paho-mqtt-cpp as a shared-only library and does not include libmeos. Four changes make the build pass: - flake.nix: add stock paho-mqtt-c + paho-mqtt-cpp to baseThirdPartyDeps; pass -DNES_ENABLE_MEOS=OFF in both defaultPackage and devShell cmakeFlags. - nes-plugins/CMakeLists.txt: introduce NES_ENABLE_MQTT and NES_ENABLE_MEOS options that gate the respective plugin subdirectories via activate_optional_plugin(). - nes-plugins/Sources/MQTTSource, nes-plugins/Sinks/MQTTSink: select PahoMqttCpp::paho-mqttpp3-static when available, fall back to the shared PahoMqttCpp::paho-mqttpp3 target (Nix only ships the shared variant). - nes-physical-operators: gate all MEOS-specific add_plugin calls and the nes-meos link behind if(NES_ENABLE_MEOS) in three CMakeLists files (top-level, Functions/Meos, Aggregation/Function/Meos). - CMakeLists.txt (root): declare option(NES_ENABLE_MEOS) and add_compile_definitions(NES_ENABLE_MEOS) before the nes-* subdirectory loop so the preprocessor symbol is visible to all sibling components. - nes-query-optimizer/LowerToPhysicalWindowedAggregation.cpp: guard the TemporalSequenceAggregationPhysicalFunction include and instantiation with #ifdef NES_ENABLE_MEOS so the translation unit compiles and links when MEOS is disabled.
Add TFLOAT_SIN, TFLOAT_COS, TFLOAT_TAN as per-event scalar operators following the extract-marshaler pattern from W25. Each takes (value:FLOAT64, ts:UINT64), constructs a MEOS single-instant temporal via tfloat_in, applies the trig C function, and extracts the FLOAT64 result via tfloat_start_value. Logical and physical function pairs registered as NES plugins; SQL parser extended with TFLOAT_SIN/COS/TAN tokens in the functionName rule and 2-arg case blocks.
Add TFLOAT_CEIL, TFLOAT_FLOOR, TFLOAT_RADIANS, TFLOAT_DEGREES as per-event scalar operators following the extract-marshaler pattern from W44. Each takes (value:FLOAT64, ts:UINT64), constructs a MEOS single-instant temporal via tfloat_in, applies the scalar C function, and extracts the FLOAT64 result via tfloat_start_value. TFLOAT_DEGREES hardcodes normalize=false. Logical and physical function pairs registered as NES plugins; SQL parser extended with TFLOAT_CEIL/FLOOR/RADIANS/DEGREES tokens in the functionName rule and 2-arg case blocks.
Add TFLOAT_SHIFT_VALUE and TFLOAT_SCALE_VALUE as per-event scalar operators following the extract-marshaler pattern. Each takes (value:FLOAT64, ts:UINT64, param:FLOAT64), constructs a MEOS single-instant temporal via tfloat_in, applies the shift or scale, and extracts the FLOAT64 result via tfloat_start_value. Logical and physical function pairs registered as NES plugins; SQL parser extended with TFLOAT_SHIFT_VALUE/SCALE_VALUE tokens in the functionName rule and 3-arg case blocks.
…s (W47) Adds per-event NES operators backed by `tnumber_abs` (2-arg: value, ts) and `tfloat_shift_scale_value` (4-arg: value, ts, shift, width). Each operator constructs a single-instant tfloat, applies the MEOS function, and returns the resulting double. Logical/physical function pairs, plugin registrations, grammar tokens, and parser case blocks are included.
Adds per-event NES operators backed by `add_tfloat_float`, `sub_tfloat_float`, `mul_tfloat_float`, and `div_tfloat_float` (3-arg each: value, ts, scalar). Each operator constructs a single-instant tfloat, applies the MEOS arithmetic function against a constant scalar, and returns the resulting double. Logical/physical function pairs, plugin registrations, grammar tokens, and parser case blocks are included.
Adds per-event NES operators backed by `add_tnumber_tnumber`, `sub_tnumber_tnumber`, `mul_tnumber_tnumber`, and `div_tnumber_tnumber` (3-arg each: value1, value2, shared-ts). Each operator constructs two co-instant tfloats, applies the MEOS element-wise arithmetic function, and returns the resulting double. Logical/physical function pairs, plugin registrations, grammar tokens, and parser case blocks are included.
…MBER_TNUMBER NES operators (W50) Adds per-event NES operators backed by temporal_round (3-arg: value, ts, maxdd), tdistance_tfloat_float (3-arg: value, ts, d), and tdistance_tnumber_tnumber (3-arg: value1, value2, ts). Each operator constructs one or two co-instant tfloats, applies the MEOS function, and returns the resulting double. Logical/physical function pairs, plugin registrations, grammar tokens, and parser case blocks are included.

Superseded by the generator-derived canonical surface: the Nix build fix (#171), the per-event operator generator (#185), and the 615-op generated surface — every operator this PR adds is regenerated from the MobilityDB master IDL and compile-verified there (generator==committed enforced by a drift-guard CI). Folding this wave into that deliverable; reopen if a specific operator needs attention. |
