a4c2098502 malloc_sysv used before initialized, reported in PR4002 by
Dmitrij Tejblum <dima@tejblum.dnttm.rssi.ru>

Various cleanup from Keith Bostic

Reinstate calloc() as a separate funtion, in its own source/object file.
leave the manpage integrated with malloc.3 and friends.  Too many things
were broken in this respect.

898607164b srandomdev: use stack junk value in the fallback code too 1997-06-15 18:23:19 +00:00
ache
98ddc15c28 Instead of copying fallback code over and over in each program,
implement (better) falback code inside srandomdev() itself.
Change return type from int to void (binary compatibility surprisely
achieved). Userland code will be changed soon.

5158253c97 Fix mutex initialization.
Malloc cannot use pthread_mutex_init() to initialize a mutex because
the mutex initialization process does a malloc!

libc_r internals skip the malloc and assign an initializer to a static
structure and point the opaque type (pthread_mutex_t in this case) to
that structure. This is done on the assumption that the mutex will never
be destroyed. This style of initialization is only valid inside libc_r
because the structure that is assigned is opaque to the user.

This fix allows a simple program to get to main() again. 8-)

a1337bb0ae Changed all paths to be relative to src/lib instead of src/lib/libc
so that all these makefiles can be used to build libc_r too.

Added .if ${LIB} == "c" tests to restrict man page builds to libc
to avoid needlessly building them with libc_r too.

Split libc Makefile into Makefile and Makefile.inc to allow the
libc_r Makefile to include Makefile.inc too.

5f73b5e6c7 Part 2 of a failed commit (cvs broke). Original message:
Back out a dubious Lite2 change to "optimise" getcwd() to look at $PWD
because it's potentially dangerous (think: symlink races).  Move
realpath() back to it's original location, and remove getcwd_physical()
by renaming it back to getcwd() and zapping the original getcwd wrapper.

Don't call imalloc until we're done initializing.
Zap contents on free() if we have "Junk" set. [*]
Various nitpicking.

[*] As a sideeffect of this change, if you are worried about
sensitive data lingering in memory, you can use the 'Junk' option
now to make sure phkmalloc zaps memory when it is returned.  add
	char * malloc_options = "J";
to your source.  Obviously there is a performance impact.
