Abstract: A method for searching for multiple sub-strings of an original text is provided. A search query is received, wherein the search query includes a plurality of sub-strings. A hash array is allocated. The hash array has a size based, at least in part, on the plurality of sub-strings and an original text. The hash array is populated with a plurality of hash values, wherein the plurality of hash values are generated using a rolling hash function, and wherein each of the plurality of hash values corresponds to a portion of the original text. A plurality of sub-string values are computed based on the plurality of sub-strings. Each of the plurality of sub-strings are determined to occur in the original text based, at least in part, on searching the hash array for the plurality of sub-string values.

Abstract: Methods and systems for cross-language program execution include setting a signature of a second programming language in a first program that is written in a first programming language. A second program that is written in the second programming language is called from the first program, such that the second program omits checks to verify a runtime environment for the second programming language based on the presence of the signature.

Abstract: Techniques are described for parsing a software program using parallel processing. In one example, a method includes tokenizing input source text to form a token stream having a plurality of tokens, partitioning the token stream into partitions by division and by statement, parsing two or more of the partitions in parallel, and traversing the common symbol dictionary to detect semantic errors. Partitioning includes storing an entry representing each partition in a partition table, including scanning the token stream in reverse starting at the end of each division. Parsing the partitions in parallel includes building, for each statement partition, an annotated syntax tree (AST) to represent the statement, storing, for each symbol, an entry in a common symbol dictionary, and generating error messages corresponding to syntax errors detected while parsing the partitions.
