Transformation of computer programs and eliminating errors

摘要

A method and system for transforming a first computer program having program statements to a second computer program. A parsed first computer program is translated to the second computer program. The first computer program includes a first program statement that includes a first error. The translating includes: (i) identifying a second program statement in the parsed first computer program that includes a second error and has thrown a translation exception with respect to the second error, (ii) rolling back the translating to a predefined check point prior to the second program statement in the parsed first computer program such that the predefined check point is associated with a statement in the parsed first computer program that was successfully translated, and (iii) generating an executable equivalent translation for the second statement. After the translating, a mapping of one or more statements is generated.

1. A method for transforming a first computer program having a plurality of program statements to a second computer program, said method comprising:
translating, by one or more processors, a parsed first computer program to the second computer program, wherein the first computer program was parsed without interruption, wherein the first computer program comprises a first program statement that includes a first error and has thrown a parsing exception with respect to the first error, wherein said translating comprises: (i) identifying a second program statement in the parsed first computer program that includes a second error and has thrown a translation exception with respect to the second error prior to said translating, (ii) rolling back said translating to a predefined check point prior to the second program statement in the parsed first computer program, wherein the predefined check point is associated with a statement in the parsed first computer program that was successfully translated during said translating, and (iii) generating an executable equivalent translation for the second statement that does not throw a translation exception; and
after said translating, generating, by the one or more processors, a mapping of one or more statements in the second computer program to one or more statements in the first computer program.
