When chaining COMBOOT images, the old images now get freed correctly.
[comboot] Allow for tail recursion of COMBOOT images2009-02-17T00:47:35+00:00Michael Brown2009-02-17T00:47:35+00:00urn:sha1:8904cd55f128941d53d9a8beef71fb32a920a92d
Multi-level menus via COMBOOT rely on the COMBOOT program being able
to exit and invoke a new COMBOOT program (the next menu). This works,
but rapidly (within about five iterations) runs out of space in gPXE's
internal stack, since each new image is executed in a new function
context.
Fix by allowing tail recursion between images; an image can now
specify a replacement image for itself, and image_exec() will perform
the necessary tail recursion.
[image] Revert "clear LOADED flag" patch2008-07-08T02:15:02+00:00Michael Brown2008-07-08T02:15:02+00:00urn:sha1:4f2861a3767700f3acb6320b10a67ea983f9ba0c
Clearing the LOADED flag actually prevents users from doing clever things
such as loading an image, then loading a patch image, then executing the
first image. (image_exec() checks for IMAGE_LOADED, so this sequence of
operations will fail if the LOADED flag gets cleared.)
This reverts commit 14c080020fb37cb34fe74213393f47bd2ad8b9bc.
[image] Clear LOADED flag on all other images when loading a new image2008-07-08T02:03:48+00:00Michael Brown2008-07-08T02:03:48+00:00urn:sha1:14c080020fb37cb34fe74213393f47bd2ad8b9bc
Loading an image may overwrite part or all of any previously-loaded
images, so we should clear the LOADED flag for all images prior to
attempting to load a new image.
Set current working URI to be that of the executable image when2007-08-07T13:50:12+00:00Michael Brown2007-08-07T13:50:12+00:00urn:sha1:cfcc41d407e99968c23c2402a600263401ee41b8

use relative URIs, should it wish to.)
Allow images to hold references to the originating URI.2007-08-02T19:18:32+00:00Michael Brown2007-08-02T19:18:32+00:00urn:sha1:d4947c05b27449b4320179d57028a0542fd1394f
Some shuffling around of the image management code; this needs tidying up.
