were JSON. This replicates a long-standing bug in the JSON processing routines, and thereby avoids breaking legacy. FossilOrigin-Name: d79a37690ce7ebb91df203170d73511da44546328043c2b3fe1786b2f0087093

# Legacy JSON bug: If the input is a BLOB that when cast into TEXT looks
|
|
# like valid JSON, then treat it as valid JSON.
|
|
#
|
|
# The original intent of the JSON functions was to raise an error on any
|
|
# BLOB input. That intent was clearly documented, but the code failed to
|
|
# to implement it. Subsequently, many applications began to depend on the
|
|
# incorrect behavior, especially apps that used readfile() to read JSON
|
|
# content, since readfile() returns a BLOB. So we need to support the
|
|
# bug moving forward.
|
|
#
|
|
# The tests in this fail verify that the original buggy behavior is
|
|
# preserved.
