deepscan issue

[edodekel]

two similar jsonpath queries give different results:

data:=[]byte({ "apiVersion": "v1", "kind": "Pod", "spec": { "containers": [ { "name": "c1", "image": "busybox", "resources": { "limits": { "cpu": "2" } } }, { "name": "c2", "image": "busybox", "resources": { "limits": { "cpu": "2" } } } ] } })

jsonslice.Get(data, "$.spec.containers[:]")

gives the expected result:

[{
"name": "c1",
"image": "busybox",
"resources": {
"limits": {
"cpu": "2"
}
}
},{
"name": "c2",
"image": "busybox",
"resources": {
"limits": {
"cpu": "2"
}
}
}]

BUT:

jsonslice.Get(data, "$..spec.containers[:]")
gives:

[{
"containers": [
{
"name": "c1",
"image": "busybox",
"resources": {
"limits": {
"cpu": "2"
}
}
},
{
"name": "c2",
"image": "busybox",
"resources": {
"limits": {
"cpu": "2"
}
}
}
]
}]

jsonslice.Get(data, "$.spec.containers[:]")

gives the expected result:

[{
"name": "c1",
"image": "busybox",
"resources": {
"limits": {
"cpu": "2"
}
}
},{
"name": "c2",
"image": "busybox",
"resources": {
"limits": {
"cpu": "2"
}
}
}]

BUT:

jsonslice.Get(data, "$..spec.containers[:]")

gives double square brackets.

[[{
"name": "c1",
"image": "busybox",
"resources": {
"limits": {
"cpu": "2"
}
}
},{
"name": "c2",
"image": "busybox",
"resources": {
"limits": {
"cpu": "2"
}
}
}]]

is it the expected result for deep scan?

[bhmj]

It is, because $.spec.containers[:] gives you a single array of all elements of containers, but $..spec.containers[:] scans the input for all the spec.containers[:] entries (there can be many of them) and puts them all in array. Each entry happens to be an array as stated above. In this particular case there is only one entry found, thus [ [...] ].

[edodekel]

so it is as designed. thanks
