while setting up a child process. This prevents the major sources of
list inconsistencies that may result from doing list manipulations
from a signal handler.
XXX - all Lst_*() operations are at risk; look for ways to avoid touching
so much global state from the signal handlers.
- don't block the signal we're about to send to ourselves to
take the default action for
- restore the signal handler for the current signal
- remove duplicate sigprocmask() call
As a result, restoring the SIGTSTP handler in JobContinueSig() is no longer
necessary.
uvm_swap_stats(). This is done in order to allow COMPAT_* swapctl()
emulation to use it directly without going through sys_swapctl().
The problem with using sys_swapctl() there is that it involves
copying the swapent array to the stackgap, and this array's size
is not known at build time. Hence it would not be possible to
ensure it would fit in the stackgap in any case.
- add libc/citrus directory.
this directory contains the common stuffs not only for locale
but also other facilities relating to i18n (e.g. iconv).
- To keep the binary compatibility for the ctype modules easily,
the interface between libc and the modules is simplified.
- For the future integrated extension, module pool is renamed
from "/usr/lib/runemodule" to "/usr/lib/i18n".
In the future, this directory will contain the modules for "iconv",
"collation", etc.
- some cosmetic changes.
- Bug fix for runetype.h; __attribute__((__packed__)) is placed at
the wrong position and it is invalid unintentionally.
But, the all members of the structures seem well-aligned. Thus,
this bug causes no problem, hopefully.
HEADS UP:
- /usr/lib/rumemodule is obsoleted. If you use the multibyte locales,
you need to install /usr/lib/i18n/* from sys/lib/i18n_module .
- The binary compatibility of /usr/share/locale/*/LC_CTYPE is probably kept.
Perhaps, the bug fix about __packed__ mentioned above breaks the
compatibility... Be careful especially on 64bit platforms.
