#422: SYSTEM:RUN-PROGRAM does not work on Java 5/6 --------------------------+------------------------------------------------ Reporter: | Owner: mevenson | Type: defect | Status: new Priority: major | Milestone: 1.5.0 Component: | Version: 1.4.0 interpreter | Resolution: | Keywords: cffi sys:run-progrom java-5 java-6 Parent Tickets: | --------------------------+------------------------------------------------
Comment (by mevenson):
After further analysis, the new plan of attack:
1. Continue to deprecate SYS:RUN-SHELL-COMMAND, as the JVM-[56] actually seem to provide all the behavior we need.
2. Fully support the current signature of the abcl-1.5.0-dev SYS:RUN- PROGRAM as extended by Pipping and Olof. The environment clearing/setting will work without alterations. "All that is needed" is to create an {{{org.abcl.util.AsyncIOManager}}} using the non-blocking file descriptor framework in {{{java.jnio}}} (introduced in JVM5) to drain/fill input/output {{{org.armedbear.lisp.Stream}}} instances. Pipping has collected a thorough test suite for the SYS:RUN-PROGRAM behavior, which will be of great use in implementation.
The use of {{{SYS:RUN-PROGRAM}}} as invoked by {{{UIOP/RUN-PROGRAM}}} as the implementation interface
TODO: transcribe details of SYS:RUN-PROGAM test suite invocation; implement {{{ASyncIOManager}}}.
