Abstract:
1. A method for version conflict checking of installable units (IUs), the method comprising: receiving, by a processor, a request for version conflict checking of a specified IU, the request comprising a version dependency relationship between IUs that are in a dependency relationship with the specified IU; obtaining the version dependency relationship between installed IUs, the version dependency relationship represented using a version dependency matrix, wherein: an element [IUn, IUc] in row n and column c of the version dependency matrix represents a dependency relationship value of an IU in the nth row and the 1st column on an IU in the 1st row and the cth column, wherein each of n and c is an integer greater than 1 and n is not equal to c; updating the version dependency relationship between the installed IUs based on the version dependency relationship between the IUs that are in the dependency relationship with the specified IU; and checking whether the specified IU has a version conflict with the updated version dependency relationship between the installed IUs.
