# All library objects contain FreeBSD revision strings by default; they may be
# excluded as a space-saving measure.  To produce a library that does
# not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
# below.  Note, there are no IDs for syscall stubs whose sources are generated.
# To included legacy CSRG sccsid strings, add -DLIBC_SCCS and -DSYSLIBC_SCCS
# (for system call stubs) to CFLAGS below.  -DSYSLIBC_SCCS affects just the
# system call stubs.

Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it. Warning, after symbol versioning is enabled, going back is not easy (use WITHOUT_SYMVER at your own risk). Change the default thread library to libthr. There most likely still needs to be a version bump for at least the thread libraries. If necessary, this will happen later. 2007-05-13 14:12:40 +00:00

Add a commented out CFLAGS entry that can be uncommented to compile thread lock debug into libc_r. I don't know if this is the best place to document this, but at least it is recorded somewhere. 8-) 1998-06-09 23:25:13 +00:00

Use growable stacks for thread stacks that are the default stack size. Cache discarded default thread stacks for use in subsequent thread creations. Create a red zone at the end of each stack (including the initial thread stack), with the hope of causing a segfault if a stack overflows. To activate these modifications, add -D_PTHREAD_GSTACK to CFLAGS in src/lib/libc_r/Makefile. Since the modifications depend on the VM_STACK kernel option, I'm not sure how to safely use growable stacks by default. Testing, as well as algorithmic and stylistic comments are welcome. 1999-07-05 00:35:19 +00:00			`CFLAGS+=-D_LOCK_DEBUG`

add pthread_cancel, obtained from OpenBSD. eischen (Daniel Eischen) added wrappers to protect against cancled threads orphaning internal resources. the cancelability code is still a bit fuzzy but works for test programs of my own, OpenBSD's and some examples from ORA's books. add readdir_r to both libc and libc_r add some 'const' attributes to function parameters Reviewed by: eischen, jasone 1999-11-28 05:38:13 +00:00			`# enable extra internal consistancy checks`
