[Bang Pham Huu]

This comes from rasdaman-user group with thread title ​WMS problem rendering with time interval .

Use this ingredients file to import two tiff files in ​https://drive.google.com/drive/folders/1eMbLcfNmg6bmC4_WasDfDDBLRYncdqqs?usp=sharing.

• First download two tiff files from the URL
• Then, rename them to 20230418.tif and 20230422.tif and import with the ingredient below:

{
  "config": {
    "service_url": "http://localhost:8080/rasdaman/ows",
    "tmp_directory": "/tmp/",
    "mock": false,
    "track_files": false,
    "automated": true
  },
  "input": {
    "coverage_id": "SSM_2_days_s",
    "paths": [
      "*.tif"
    ]
  },
  "recipe": {
    "name": "time_series_irregular",
    "options": {
      "wms_import": true,
      "scale_levels": [2, 4, 8, 16, 32, 64],
      "time_parameter": {
        "filename": {
          "regex": "(.*)\\.(.*)",
          "group": "1"
        },
        "datetime_format": "YYYYMMDD"
      },
      "time_crs": "http://localhost:8080/rasdaman/def/crs/OGC/0/AnsiDate?axis-label=\"date\"",
      "tiling": "ALIGNED [0:0, 0:999, 0:999]"
    }
  }
}

The rasql query caused segfault is:

Request: 'SELECT ENCODE((  ( scale( scale( ( ( c0[0,0:1708,0:1055] OVERLAY c0[1,0:1708,0:1055] ) ), [0:1012, 0:624] )  [0:1012, 80:624], [0:1012, 0:545] ) )  ), "png", "{\"nodata\":[0.0]}") FROM SSM_2_days_s_16 AS c0
