substitution errors for variables that don't exist.
If a machine architecture dependent makefile exists, include it
to discover if libc or libc_r is being built with NetBSD syscalls
instead of FreeBSD ones.
Put a NO_QUAD thingy around the quad makefile so that 64-bit
architectures can ignore that sh*t.
In the test for MDSRCS being empty, add all MISRCS to SRCS, rather
than just ignoring them.
Define the HIDDEN_SYSCALLS macro as empty because libc doesn't have
renamed syscalls. This avoids an undefined macro error when
libc/sys/Makefile.inc goes to look though it. HIDDEN_SYSCALLS is
used by the equivalent makefile to this one in lib/libc_r to list
those syscalls that it needs to rename so that libc_r can provide
replacement functions.
Change MACHINE references to MACHINE_ARCH.
Declare the names of the syscalls that need to be renamed to allow
for the functions that libc_r provides replacements for. This list
used to be in lib/libc/sys/Makefile.inc, but has been moved here
to keep that makefile tidy and remove the temptation for people to
add things to the list without adding a libc_r replacement function.
prototypes for the spinlock functions that will be used for thread locks.
libc will have stubs declared with weak symbols. libpthread and libc_r
will have functions that really do something.
Changed MACHINE to MACHINE_ARCH with the expectation that pc98 will
use elf the same as i386.
Nuked tahoe and vax 'cause the files they reference aren't in the
tree. If you want vax goto NetBSD. If you want tahoe... tough.
Changes to support building with _POSIX_SOURCE set to 199309L:
1. Add sys/_posix.h to handle those preprocessor defs that POSIX
says have effects when defined before including any header files;
2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE
3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now
defined in POSIX. These show up when:
_POSIX_SOURCE and _POSIX_C_SOURCE are not set or
_POSIX_C_SOURCE is set >= 199309L
and vanish when:
_POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L.
4. Explain these in man 9 posix4;
5. Include _posix.h and conditionalize on new feature test.
- Completely recoded the ypmatch cache code. The old code could leak
memory: it would allow the cache to grow, but never
shrink. The new code imposes the following limits:
o The cache is capped at a limit of 5 entries.
o Each entry expires after five seconds, at which point
its slot is freed.
o If an insertion is to be done and all five slots
are filled, the oldest entry is forcibly expired
to release its slot.
Also, the cache is implemented on a per-binding basis rather than
having a global cache covering all bindings. This means that each
bound domain has its own 5 slot cache.
- Changed clntudp_create() to clntudp_bufcreate() so that the
xmit/recv message buffer sizes can be set explicitly. NIS transactions
are rarely much larger than 1024 bytes since YPMAXRECORD is 1024.
The defaults chosen by clntudb_create() are actually much larger
than needed. I set the xmit buffer to a little over 1024 and the
recv buffer to a little over 2048. This saves a few Kbytes for each
NIS binding.
- Add my name to the copyright. I think I've made enough changes to
this file to merit it. :)
Note: these changes should go into the 2.2.x branch, but I'm waiting
on feedback from a tester to see if the cache fixes solve the reported
memory leak problem.
changes to bsd.lib.mk can handle building it early enough. Don't
use the same rule for ss_err.h and ss_err.c, else `make -jN' would
run the rule twice concurrently. Don't put ss_err.c out of order
in SRCS; doing so was a kludge to get ss_err.h built early enough
for plain `make'.
Don't put a non-generated file in CLEANFILES.
since there might be permanent entries still left after
calls to DeleteLink (it will be nullified by DeleteLink
if all entries are deleted, won't it ?)
2) in PacketAliasSetAddress, set the aliasing address
even when PKT_ALIAS_RESET_ON_ADDR_CHANGE is in effect.
Just don't clean up links in this case.
