line with BSD/OS and Linux's username limits, making transitioning from
either operating system a lot easier than it is now. I'm currently
running with this change on my system, as are several others, and have
experienced no ill effects.
This is not for 2.2! This needs to get shaken out longer term in 3.0.
Previously-approved-by: davidg
we use it in the uthreads implementation.
Moved enum pthread_mutextype here from libc_r/uthread/pthread_private.h.
Change prototype for pthread_getspecific().
support LD_HINTS_VERSION_2 that has the ldconfig pathname stored in the
ld.so.hints file (ie: a new library can be installed and used without
needing to run ldconfig -m first)
Reviewed by: nate, jdp
Obtained from: NetBSD (mostly)
for gcc >= 2.5 and no-ops for gcc >= 2.6. Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.
- use .for loops instead of shell for loops. This means we can be
shown what is happening while it's going, rather than some pacifier
"echo" statement.
- use "${INSTALL} -C", nuke the "cmp -s" hack
- for "copies" mode, the include files are no longer touched each time
the world is built. (ie: no rm -rf. symlinks are removed, mtree builds
the new dirs or confirms the existing ones)
- osreldate.h is build in the local dir and conditionally installed,
rather than built in /usr/include and either renamed or deleted.
Here are the diffs for libc_r to get it one step closer to P1003.1c
These make most of the thread/mutex/condvar structures opaque to the
user. There are three functions which have been renamed with _np
suffixes because they are extensions to P1003.1c (I did them for JAVA,
which needs to suspend/resume threads and also start threads suspended).
I've created a new header (pthread_np.h) for the non-POSIX stuff.
The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented
doesn't work. I think its best to delete it. I don't think libc_r needs
tags anyway, 'cause most of the source is in libc which does have tags.
also:
Here's the first batch of man pages for the thread functions.
The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was
inherited from /usr/src/lib/libc/Makefile that should only be done with
libc.
also:
I should have sent this diff with the pthread(3) man page.
It allows people to type
make -DWANT_LIBC_R world
to get libc_r built with the rest of the world. I put this in the
pthread(3) man page. The default is still not to build libc_r.
also:
The diff attached adds a pthread(3) man page to /usr/src/share/man/man3.
The idea is that without libc_r installed, this man page will give people
enough info to know that they have to build libc_r.
in the POSIX section for a log time. The non-POSIX getgrouplist() and
setgroups() were recently added to the POSIX section although setgroups()
was already in the non-POSIX section.
easier to use in mixed environments:
- Add three new members to the request structure:
- a filename specification
- a database type specification
- a system byte prder specification
These allow the client to ask the server for a particular type of
database (Berkeley DB hash/btree/recno, GNU GDBM, dbm, ndbm, etc...)
and get back a meaningful error if the server doesn't support it.
The byte order spec is needed if the database type is byte order
sensntive. You don't, for example, want to read an ndbm database
from a big endian machine on a little endian machine (the ndbm code
will explode). The filename spec lets the client handle things like
ndbm which uses two seperate files per database (foo.dir and foo.pag).
The client can ask for each half, one at a time.
- Add a list of database types and byte order values. Each list has
a wildcard 'ANY' entry which lets the client ask for whatever the
server supports. (XFR_ENDIAN_ANY is useful with the Berkeley DB hash
method for instance, since it isn't byte order sensitive.)
- Add two newserver failure codes: XFR_DB_TYPE_MISMATCH and
XFR_DB_ENDIAN_MISMATCH. The server uses these to tell the client
that it doesn't support the requested type/byte order.
These changes were made at the suggestion of Thorsten Kukuk, the
current maintainer of the Linux ypserv distribution. This allows
Linux and FreeBSD NIS servers to use the same ypxfrd protocol and
avoid accidentally exchanging incompatible map files.
not based on gpl'ed code, just prototype and usage. I'm not 100% certain
they behave the same while the system is in trouble (eg: malloc() failing)
but in those circumstances all bets would be off anyway.
These routines work like sprintf() and vsprintf(), except that instead of
using a fixed buffer, they allocate memory and return it to the user
and it's the user's responsibility to free() it. They have allocate as
much memory as they need (and can get), so the size of strings it can deal
with is limited only by the amount of memory it can malloc() on your
behalf.
There are a few gpl'ed programs starting to use this interface, and it's
becoming more common with the scares about security risks with sprintf().
I dont like the look of the code that the various programs (including
cvs, gdb, libg++, etc) provide if configure can't find it on the system.
It should be possible to modify the stdio core code to provide this
interface more efficiently, I was more worried about having something
that worked and was secure. :-) (I noticed that there was once intended
to be a smprintf() routine when our stdio was written for 4.4BSD, but it
looks pretty stillborn, and it's intended interface is not clear). Since
Linux and gnu libc have this interface, it seemed silly to bring yet
another one onto the scene.
If _ANSI_SOURCE or _POSIX_SOURCE is defined, then <ctype.h> had to
be included before <stddef.h> or <stdlib.h> to get rune_t declared.
Now rune_t is declared perfectly bogusly in all cases when <ctype.h>
is included.
This change breaks similar (but more convoluted) convolutions in the
stddef.h in gcc distributions. Ports of gcc should avoid using the
gcc headers.
getnetgrent.c:
- Catch one bogon that snuck by: in _listmatch(), check for '\0'
rather than '\n'; strings returned from yp_match() are terminated
with a nul, not a newline.
getpwent.c:
- Rip out all of the +inclusion/-exclusion stuff from before and
replace it with something a little less grotty. The main problem
with the old mechanism was that it wasted many cycles processing
NIS entries even after it already knew they were to be exlcuded
(or not included, depending on your pointof view). The highlights
of these changes include:
o Uses an in-memory hash database table to keep track of all the
-@netgroup, -user, and -@group exclusions.
o Tries harder to duplicate the behavior normally obtained when using
NIS inclusions/exclusions on a flat /etc/passwd file (meaning things
come out in much the same order).
o Uses seperate methods for handling getpwent() and getpwnam()/getpwuid()
operations instead of trying to do everything with one general
function, which didn't work as well as I thought it would.
o Uses both getnetgrent() and innetgr() to try to save time where
possible.
o Use only one special token in the local password database
(_PW_KEYYPBYNUM) instead of seperate tokens to mark + and -
entries (and stop using the counter tokens too). If this new
token doesn't exist, the code will make due with the standard
_PW_KEYBYNUM token in order to support older databases that
won't have the new token in them.
All this is an attempt to make this stuff work better in environments
with large NIS passwd databases.
