[armedbear-ticket] [armedbear] #56: Eliminate use of temporary files in COMPILE and COMPILE-FILE
#56: Eliminate use of temporary files in COMPILE and COMPILE-FILE -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: ehuelsmann Type: enhancement | Status: new Priority: major | Milestone: Component: compiler | Version: Keywords: | -------------------------+-------------------------------------------------- The functions COMPILE and COMPILE-FILE use temporary files for the class files generated by the compiler.
However, COMPILE directly loads them back into memory and deletes the temp file, while COMPILE-FILE deletes the temp file after adding it to a ZIP archive.
This ticket exists to indicate that infrastructure is required to better manage where output goes to, abstracting from the temp files.

Comment(by trittweiler):
When working on this, I think it makes sense to base COMPILE-FILE on a COMPILE-FROM-STREAM. The latter function could then find use in ABCL's SWANK backend (for implementing C-c C-c.) ECL, and CMUCL both provide such a COMPILE-FROM-STREAM function.

Changing ticket title: temp files are no longer used with COMPILE; only with COMPILE-FILE now.

Comment(by ehuelsmann):
An intermediate step could be to store the temp files in the location indicated by java.io.tmpdir property. This property should point to a location on local disk, eliminating any network turn-arounds required to stat(), read and delete the files during compilation.
That should at least speed up compilation by a lot in case the target is non-locally stored.

Comment:
The suggestion in the previous comment should be doable relatively short term.

I think has been addressed by Alessio long ago.

Comment:
I don't recall ever fixing it, and Erik confirms COMPILE-FILE is still using temporary files.
