System and method for providing a java code release infrastructure with granular code patching

A method for providing a JAVA code release infrastructure with granular code patching, comprising:

• providing one or more JAVA code patches, each comprising at least one resource unit, each resource unit comprising metadata and file components;
• patching one or more to-be-patched JAVA code libraries, each comprising at least one such resource unit;
• comparing the metadata for each such resource unit in the JAVA code patches to the metadata for each such corresponding resource unit in the to-be-patched JAVA code libraries;
• and
• merging each such resource unit in the JAVA code patches into the to-be-patched JAVA code libraries for each such corresponding resource unit that is out-of-date.

A system for patching staged code in a staged JAVA code release infrastructure, comprising:

• a staged code repository maintaining one or more staged to-be-patched JAVA code libraries, each staged to-be-patched JAVA code library comprising at least one resource unit, each resource unit comprising metadata and file components;
• a staged patch repository storing one or more JAVA code patches, each JAVA code patch comprising at least one resource unit corresponding to one such resource unit specified in a JAVA code patch definition;
• and
• a patch tool accessing one or more JAVA code patches in the staged patch repository, comprising:
• a compare module comparing the metadata for each resource unit in the JAVA code patches to the metadata in the staged to-be-patched JAVA code libraries for each such corresponding resource unit;
• and
• a merge module merging each resource unit in the JAVA code patches into the staged to-be-patched JAVA code libraries for each such corresponding resource unit that is out-of-date.

A method for patching staged code in a JAVA code release infrastructure, comprising:

• maintaining one or more staged to-be-patched JAVA code libraries in a staged code repository, each staged to-be-patched JAVA code library comprising at least one resource unit, each resource unit comprising metadata and file components;
• accessing one or more JAVA code patches in a staged patch repository, each JAVA code patch comprising at least one resource unit corresponding to one such resource unit specified in a JAVA code patch definition;
• comparing the metadata for each resource unit in the JAVA code patches to the metadata in the staged to-be-patched JAVA code libraries for each such corresponding resource unit;
• and
• merging each resource unit in the JAVA code patches into the staged to-be-patched JAVA code libraries for each such corresponding resource unit that is out-of-date.

A computer-implemented method for patching code, the method comprising:

• downloading, to a client machine, from a server machine that is separate from the client machine, one or more patches that were generated on the server machine;
• comparing, at the client machine, (a) contents of the one or more patches to (b) code that is not resident on the server machine;
• based on the comparing, determining one or more out-of-date portions within the code;
• and
• applying at least a part of the one or more patches to the out-of-date portions without applying any part of the one or more patches to parts of the code other than the out-of-date portions.
