Abstract

A computer-implemented method includes receiving a set of complete source instructions to process a source code entity, an incremental build part, and a set of file definitions. The method analyzes the set of complete source instructions. The method identifies, from the set of analyzed source instructions, a set of operations that reference the incremental build subset. The method repeats: (i) determining, for each operation, whether any additional files are affected by the operation, the additional files forming a set of affected files; (ii) creating a combined set of files, the combined set of files consisting of the set of affected files and the incremental build subset; and (iii) updating the set of operations to include those from the analyzed source instructions that reference the combined set of files; until no new files are added to the combined set of files. The method generates a set of incremental source instructions.

Claims

1. A computer-implemented method comprising:

receiving a set of complete source instructions, said set of complete source instructions being instructions to process a source code entity, said complete source instructions referencing a set of files;

receiving one or more incremental build parts;

receiving a set of file definitions, said set of file definitions identifying an incremental build subset, said incremental build subset being those of said set of files that comprise said one or more incremental build parts;

analyzing said set of complete source instructions to yield a set of analyzed source instructions, based on substituting all variables and expanding all procedures therein;

identifying, from said set of analyzed source instructions, a set of operations, said set of operations being those operations of said set of analyzed source instructions that reference said incremental build subset;

repeating;

determining, for each operation of said set of operations, whether any additional files are affected by said operation, said additional files forming a set of affected files;

responsive to said set of affected files having one or more elements, creating a combined set of files, said combined set of files consisting of said set of affected files and said incremental build subset; and

updating said set of operations to include those from said analyzed source instructions that reference said combined set of files;

until no new files are added to said combined set of files; and

generating a set of incremental source instructions, based on said set of operations in combination with said set of complete source instructions, organized according to dependencies.

2. The computer-implemented method of claim 1, wherein said set of complete source instructions is expressed in a job control language.

3. The computer-implemented method of claim 2, wherein creating a combined set of files comprises:

identifying, within said set of affected files, a set of output files;

pruning, within said set of affected files, said set of output files; and

creating said combined set of files, said combined set of files consisting of said set of affected files and said incremental build subset.

4. The computer-implemented method of claim 3, wherein pruning said set of output files comprises:

identifying, within said set of affected files, a set of standard library files for one or more computer languages in which said set of complete source instructions is expressed; and

removing said set of standard library files from said set of affected files.

5. The computer-implemented method of claim 1, wherein said set of complete source instructions includes a set of ordering instructions.

6. The computer-implemented method of claim 5:

further comprising organizing said set of operations based on said set of ordering instructions to generate a set of organized operations; and

wherein generating a set of incremental source instructions is based on said set of organized operations in combination with said set of complete source instructions, organized according to dependencies.
