Efficient detection of architecture related bugs during the porting process

A system, comprising:

• one or more processors;
• and
• a memory containing a program, which when executed by the one or more processors, performs an operation comprising:
• identifying a first commit of a plurality of commits for a software project, wherein a source code of the first commit is executable in a first system architecture;
• determining, based on a set of tests run against a built source code of the first commit for the first system architecture and a second system architecture, that the first commit is a latest working build for the first and second system architectures;
• computing a score for each commit in a first set of the plurality of commits, wherein each score reflects a likelihood of success in porting the source code of the respective commit from the first system architecture to the second system architecture, wherein a version of each commit in the first set of commits is between a version of the first commit and a current version of the software project;
• identifying a second commit of the first set of commits by determining the score of the second commit exceeds a rank threshold, wherein the score for the second commit is computed from a weighted sum of a number of occurrences of each of a plurality of attributes of source code of the second commit that are predicted to result in invalid architecture errors when porting the second commit to a platform of the second system architecture;
• building the source code of the second commit for execution on the second system architecture;
• and
• determining that the source code of the second commit did not build successfully for the second system architecture based on an error at a first line of the source code of the second commit.

A computer program product, comprising:

• a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to perform an operation comprising:
• identifying a first commit of a plurality of commits for a software project, wherein a source code of the first commit is executable in a first system architecture;
• determining, based on a set of tests run against a built source code of the first commit for the first system architecture and a second system architecture, that the first commit is a latest working build for the first and second system architectures;
• computing a score for each commit in a first set of the plurality of commits, wherein each score reflects a likelihood of success in porting the source code of the respective commit from the first system architecture to the second system architecture, wherein a version of each commit in the first set of commits is between a version of the first commit and a current version of the software project;
• identifying a second commit of the first set of commits by determining the score of the second commit exceeds a rank threshold, wherein the score for the second commit is computed from a weighted sum of a number of occurrences of each of a plurality of attributes of source code of the second commit that are predicted to result in invalid architecture errors when porting the second commit to a platform of the second system architecture;
• building the source code of the second commit for execution on the second system architecture;
• and
• determining that the source code of the second commit did not build successfully for the second system architecture based on an error at a first line of the source code of the second commit.
