cgd 981d496969 Change file system file-open semantics slightly: if file system returns
EINVAL, that error code is ignored, leaving whatever other meaningful
error code that might have previously been returned intact.  Stand-alone
file system implementations return EINVAL typically when the file system
is not recognized (i.e. cd9660_open on a UFS file system, ufs_open on a
cd9660 file system, etc.).  This meant that if you had multiple file
systems in a file system switch, the first returned ENOENT (because
it recognized the file system type, but the file wasn't there) and
the second returned EINVAL (because it didn't recognize the file system
type), errno would be set to EINVAL.  Now it'll be set to ENOENT.

It would probably make sense to have file systems return a special
error code to indicate "this file system is unrecognized," which
could then be special-cased, but that's a fair bit more invasive.

cgd da4932bff2 add EINVAL and ENOTDIR, as suggested by Matthias Drochner 1997-01-25 00:37:50 +00:00
cgd 192e22f5b7 isonum_722 and isonum_732 are now back in iso.h 1997-01-24 00:53:40 +00:00
cgd 6f0de181b1 update for iso.h changes which remove the need for the nastiness that was here 1997-01-24 00:29:19 +00:00
cgd 3ca5f41d59 clean up substantially. Transform clean, depend, cleandir targets from ::
to :, so they can be used e.g. with <bsd.prog.mk>.  Standardize variable
names used to configure kernel libraries.

Variables used by these Makefile.inc's are:

S		must be set to the top of the 'sys' tree.
${LIB}DST	may be set to the location of the directory where library
		objects are to be built.  Defaults to ${.OBJDIR}/lib/${lib}.
${LIB}_AS	may be set to 'obj' to build a object from the library's
		object files.  (Otherwise, a library will be built.)
		Defaults to 'library'.
${LIB}MISCMAKEFLAGS
		Miscellaneous flags to be passed to the library's Makefile when
		building.  See library's Makefile for more details about
		supported flags and their default values.

(where LIB is KERN, SA, or Z, and lib is kern, sa, or z, depending on which
library's Makefile.inc is being discussed.)
1997-01-23 22:29:07 +00:00
cgd 2ce4559663 clean up variable use, standardize with other kernel library Makefiles.
rename 'NO_NET' variable to SA_INCLUDE_NET, which defaults to 'yes' but can
be set differently.  kill EXTRACFLAGS, add SACPPFLAGS (generated from
CPPFLAGS by Makefile.inc) to CFLAGS.  Add support for including gzipped-file
read support, enabled by setting SA_USE_CREAD to yes (defaults to no).
1997-01-23 22:19:56 +00:00
cgd 25bd886ba9 fix a typo (ZPPFLAGS should have been ZCPPFLAGS) 1997-01-22 01:36:30 +00:00
cgd ea27b7aa31 Add a whole bunch of features, from Matthias Drochner:
best-fit, rather than first-fit, algorithm.
	ability to handle free()s with zero size (needed for gzip read
	    support).
	ability to start the heap someplace else (defined by HEAP_START).
	ability to limit growth of the heap (via HEAP_LIMIT).
	debugging sanity checks (ifdef DEBUG).
	allocation tracing support, to help debugging (ifdef ALLOC_TRACE).
and from me:
	ability to pick a (smaller) first-fit algorithm (via ALLOC_FIRST_FIT).
	lots of comments.

If heap limits and all of the debugging features are disabled (the default),
and ALLOC_FIRST_FIT is defined (not the default), compiled with -O on the
alpha the new version is the same (object) size as the old version.

cgd 862c1d585c code to open/close/read/lseek gzipped files, from Matthias Drochner. 1997-01-22 00:40:07 +00:00
cgd 21979e8d6b define these functions with an 'o' prepended to their names if
__INTERNAL_LIBSA_CREAD is defined (so that they can be used by the
compressed-read code).
1997-01-22 00:38:09 +00:00
cgd b581a80665 prototype lseek(). also, prototype oopen(), oclose(), oread(), and olseek()
if __INTERNAL_LIBSA_CREAD is defined.
1997-01-22 00:37:23 +00:00
cgd d867ed50cc add strchr() to libkern. strchr.c copied from libc's "index.c", but with
appropriate definitions so that it'll build strchr(), and so that it builds
correctly in libkern (needed to #define NULL).
1997-01-18 02:33:38 +00:00
cgd 493bd9e110 fix file system buffer leak that occurs if an error occurs (e.g. file not
found) during the file system open function after having read some data
from the disk.  From  Matthias Drochner (PR 3120).
1997-01-17 20:17:58 +00:00
cgd 9596fd8a77 only call the device close routine on a (fall-through) error if
F_NODEV isn't set in the file flags for the file being opened.
Pointed out by Matthias Drochner in PR 3122.  (fix equivalent to
the one he included, but stylistically different.)

fix suggested by Jason Thorpe.

cgd b1f42c3a13 add memcmp, implemented as a wrapper around bcmp() (like memcpy() is
implemented as a wrapper around bcopy()).

cgd f515ce7937 add sources, all copied verbatim from src/lib/libz 1997-01-16 00:21:43 +00:00
cgd e18d476d7c add Makefiles to build kernel 'libz' library, expected to be used by
boot blocks to load compressed images.  Sources and headers are copied
from src/lib (src/lib/libz, in particular) by making the 'update-sources'
target in this directory.  This library builds in a manner similar to
libkern; much of the Makefile hackery was taken from there.
