'RELENG_3_1_0_RELEASE'. This commit was manufactured to restore the state of the 3.1-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Rename "source" as "include". Make it capable of including forth source, while stripping #@- functionality (in the BOOT_FORTH case). Add builtin "more". (This is already in help.common -- must got into one of Mike's MFC). Make bf_run return ficlExec() result code. Push "interpret" on the execution stack before calling ficlExec() (not doing this was a bug, if we want ficlExec() to recurse). Add EXCEPTION and MEMORY-ALLOC word sets. Fix "evaluate" to respect buffer size. Make builtins "throw" errors instead of pushing them on the stack. Move error message printing from bf_command() to bf_run(). Make builtins state-aware. Fix "type" not to use fixed sized buffers. Add version words to ficl. Add trace facility to ficl. Add words $ and % to replace @ and - in "include". Approved by: jhk

Replace duplicated "old" linker set definitions with an include of

. Note, this isn't used on the i386.

Fall back to /boot/boot.conf, if /boot/loader.rc was not fount. This is

Implement a simple LRU block cache. By default this is initialised to 16k,

1998-11-02T23:28:11Z

and will bypass transfers for more than 8k. Blocks are invalidated after 2 seconds, so removable media should not confuse the cache. The 8k threshold is a compromise; all UFS transfers performed by libstand are 8k or less, so large file reads thrash the cache. However many filesystem metadata operations are also performed using 8k blocks, so using a lower threshold gives poor performance. Those of you with an eye for cache algorithms are welcome to tell me how badly this one sucks; you can start with the 'bcachestats' command which will print the contents of the cache and access statistics.

Export an interface for presetting the ISA PnP read port address.

Make the EISA ID formatter generally available

Make ISA PnP work. This successfully enumerates as many ISA devices as I

can fit into my test machine. - Move to using STAILQs rather than ad-hoc singly-linked lists. - Use a mostly procedural interface to the PnP information. This improves data-hiding. Implement a new linker-set technique (currently on i386 only but should work on Alpha as well). This is a good candidate for replacing the current gensetdefs cruft completely.

loader <-> kernel preload module interface constants moved to common file.

Remove Mike's explicit data structures for dependency info. This is done via DT_NEEDED etc in the dynamic section for now. This may need to be revisited later on.

Sync the MODINFO constants with

Remove debugging in command_read(). Correctly strip leading controls on script commands. Make 'ls' more DWIM in regard to pathnames. We can still do better.

- VERBOSE_LS is obsolete, as the heap is much better behaved now.

- Don't whine about nodes we can't stat(); these are usually symlinks that lead out of the filesystem. - Autoboot is now controlled by $autoboot_delay, which is a value in seconds or NO to disable autoboot. - Don't autoboot at the end of boot.conf if we have already tried. - Add a 'read' command to complement 'echo'. Both are still hidden. - Improve the 'source' command/function so that it is possible to source scripts off removable media. The entire script is read and saved before beginning execution. Script lines beginning with '@' will not be echoed when being executed. Script execution will normally terminate at the first error, however if the script line begins with '-' this behaviour is overriden for that command.
