grub_print_error() instead. This will let user know why we're entering
rescue mode.
Based on suggestions from Sam Morris.
A new machine-specific function "grub_machine_set_prefix" is
defined. This is called after loading modules, so that a prefix
initialization can use modules. Also, this change adds an
intensive debugging feature for the memory manager via the
configure option "--enable-mm-debug".

PART.LEN.

the message.

(grub_set_root_dev): Register grub_env_write_hook for "root". Use
grub_env_set instead of grub_device_set_root.
* kern/env.c (HASHSZ): Reduced to 13, because GRUB does not need
many variables.
(grub_env_set): Set ENV->VALUE to the result of ENV->WRITE_HOOK
rather than calling ENV->WRITE_HOOK afterwards.
(grub_env_get): Return the result of ENV->READ_HOOK rather than
passing a pointer of a pointer.
(grub_register_variable_hook): Change the types of "read_hook" and
"write_hook" to grub_env_read_hook_t and grub_env_write_hook_t,
respectively.
Allocate the default empty string on the heap, because this string
may be freed later.

(grub_device_set_root): Likewise.

make sure that DIRNAME terminates with '/', so that
grub_fat_find_dir will fail if PATH is not a directory.

from DIRNAME.
Use the qualifier auto for print_files and print_files_long.
If FS->DIR sets GRUB_ERRNO to GRUB_ERR_BAD_FILE_TYPE, try DIRNAME
as a regular file.
Put a newline only if there is no error.
(grub_cmd_ls): Remove grub_ls_print_files, because this is not
used.
All symbols prefixed with PUPA_ and pupa_ are renamed to GRUB_
and grub_, respectively. Because the conversion is trivial and
mechanical, I omit the details here. Please refer to the CVS
if you need more information.

(pupa_tab_complete): Added prototypes for print_simple_completion,
print_partition_completion, add_completion, iterate_commands,

* kern/rescue.c (pupa_rescue_cmd_rmmod): Call pupa_dl_unload, if
possible.
* kern/dl.c (pupa_dl_ref): Refer dependending modules

Don't call pupa_dl_unload implicitly, because PUPA can crash if
a module is unloaded before one depending on that module is
unloaded.

(compact_mem_regions): Likewise.
(pupa_machine_init): Set PUPA_LOWER_MEM and PUPA_UPPER_MEM to
the size of the conventional memory and that of so-called upper
memory (before the first memory hole).
Instead of adding each found region to free memory, use
add_mem_region and add them after removing overlaps.
Also, add only 1/4 of the upper memory to free memory. The rest
is used for loading OS images. Maybe this is ad hoc, but this
makes it much easier to relocate OS images when booting.
* kern/rescue.c (pupa_rescue_cmd_module): Removed.

Use ioctl only if the OS file is a block device.

Don't follow symbolic links.
Fix the path-constructing code.
* util/i386/pc/biosdisk.c [__linux__] (BLKFLSBUF): New macro.
(pupa_util_biosdisk_open) [__linux__]: Get the size of a device
by a BLKGETSIZE ioctl first, because block devices don't fill
the member st_mode of the structure stat on Linux.
[__linux__] (linux_find_partition): Use a temporary buffer
REAL_DEV for the working space. Copy it to DEV before returning.
(open_device) [__linux__]: Call ioctl with BLKFLSBUF to make the
buffer cache consistent.
(get_os_disk) [__linux__]: Use the length 5 instead of 4 for
strncmp. The previous value was merely wrong.
(pupa_util_biosdisk_get_pupa_dev): Use stat instead of lstat.
* fs/fat.c (pupa_fat_read_data): Shift 4 instead of 12 when the
FAT size is 12. The previous value was merely wrong.
* kern/main.c (pupa_main): Don't split the starting message from
newlines.
