Abstract: Methods, systems, and computer programs are presented for a policy to enable customers to create and apply allowed items and restricted items provided by third-party managers. User code is received by a cloud data platform, the code for performing an operation. The cloud data platform receives a policy including allowed items and restricted items. The cloud data platform compares the allowed and restricted items to a specification, and determines a difference based on the comparison. The cloud data platform determines whether to permit the operation based at least in part on the differences.

Abstract: Methods, systems, and computer programs are presented for a packages policy object to enable customers to create and apply packages policies provided by third-party package managers. A user-defined function (UDF) is received by a cloud data platform. The UDF includes code related to at least one operation to be performed. The cloud data platform receives a package policy including at least one allowlist and at least one blocklist and compares the at least one allowlist and the at least one blocklist to the at least one package specification. The cloud data platform computes a difference set based on the comparison. The difference set includes metadata associated with one or more packages to remove. The cloud data platform determines whether the UDF is permitted based at least in part on the difference set.

Abstract: Non-toxin adhesiveless slipper includes an upper portion and a lower portion; wherein the upper portion and the lower portion are bonded with each other by an adhesive film. A processing method for bonding an upper portion and a lower portion together, including steps of: a. heat melting the EVA and the EAA to form a fluid compound, and blowing the fluid compound on a bottom surface of the upper portion to form an adhesive film; b. placing an isolated paper on the adhesive film; c. placing the upper portion into a heat-pressing machine to ensure the adhesive film and isolated paper securely attached on the bottom surface of the upper portion; d. placing a rubber sheet on a mold to process a heat pressing and then removing the remaining rubber on the contours of the mold to form the lower portion; e. placing the upper portion and the lower portion into a sectional die, and then processing the heat-pressing.
