Re: NIS and libc6/hamm?
Hi! Can someone tell me if NIS is working in the current hamm release? (Someone here mentioned that it is not, so I want to know for sure before I upgrade my system.) Note, that the NIS server is still running Debian 1.2. The clients will be eventually upgraded. It works for me, but I haven't got any reply on my questions what was wrong for others. Important is to use compat as sole method for passwd, group and shadow in /etc/nsswitch.conf. The nis package still uses libc5 and has to be changed a little to compile with libc6.

to be thread-safe. This is, however, not practical or feasible for every library package. Making a library thread-safe involves quite a lot of work, much of it nontivial. Thread-safe means that the following changes must be made to the library packages: - compile the library using -D_RENTRANT or -D_THREAD_SAFE - there may be no permanent data residing in the library memory that can be different for different threads. this means in the first place no static or global variables that are not in some way protected from access by a different threads via mutexes. - all write access to files from a library must be both protected using some file locking mechanism in addition to using mutexes. - at least some library functions must be protected from being used at the same time by two threads sharing the same memory space. This is done using mutexes.

If a library has a thread-safe version, the debian package should use this. The performance deficits usually are very small when not linking to libpthreads so only if there are serious reasons, the debian package may include the non-thread-safe version.

Conflicts Dependencies for hamm packages The libfoog package _has_ to conflict with all versions of the libfoo package before it was made to use the libc5-compat directory. Furthemore it should depend on libc6. The libfoog-dev package must depend on libc6-dev and the libfoog package of the same release. It has to conflict with the libfoo-dev package. The hamm libfoo package has to depend on libc5 and has to conflict with libfoo-dev. The libfoo-altdev package has to depend on the libfoo package of the same release and on libc5-altdev. 6. Handling bugfixes for Debian 1.3 (bo) Using the dependencies from Section 5. there will be problems with making bugfix releases for bo. These have to be handled carefully as otherwise there may be tremendous problems for people using hamm systems. As there is one package name used for both hamm and bo that stays the same (libfoo), we have to very careful. The following steps should be followed: i) when making a bo bugfix release, be sure to make a hamm release at the same time, using a higher release number for the hamm release. Update the hamm package's conflicts according to section 5. ii) Any newly uploaded bo package for libfoo _has_ to conflict with libc6, libfoo-altdev and libfoog. [3] iii)Any newly uploaded libfoo-dev package for bo has to depend on libc5-dev. As libc5-altdev conflicts with libc5-dev this will automatically make sure this apckage is not used on a hamm system. 7. Requirements on compiler packages The compiler and binutils packages have to provide working development environments for both C libraries. Basically (that is from the compiler standpoint) there is no real difference between the two environments, only some paths and automatic definitions have to be changed. All this can be done (and is in fact done) by supplying a different specs file in a different location. The gcc packages do this as follows: The gcc package uses libc6 by default and is installed in /usr/bin. The alt-gcc package uses libc5 by default and is located in /usr/i486-linuxlibc1/bin. By prepending this to the path this can be made the default. These requirements are fulfilled by the current gcc packages. Remarks: [1] the name of a library package often includes the major version number of the library. If so, the 'g' should come before this number, e.g. libgdbmg1 as package name for the libc6 based runtime package for libgdbm. [2] The location ../libc5-compat was introduced in the ldso package. As ldso is a package on all Linux distributions we'll keep it for compatibility with other distributons even though /usr/i486-linuxlibc1/lib would be more consistent. [3] The point is that a package submitted to bo which has a higher revision number may not be used in hamm. So any package that has a hamm release with a smaller release number has to conflict with libc6 and the rest mentioned.

More locale problems for libc5 libc6
Well, there really are some strange problems with the locales 2.0.4-1
package. Strangely some of the compiled locale files use the old
format, some the new one. I really cannot understand how this
happened, but it did.
All people having problems with locales should run the included
script. This will make some problems disappear. The libc5 I will
release tomorrow for hamm will understand these locale files (though
the current 5.4.33-4 doesn't). This should, however, fix some problems
with libc6 and locales. Anyone who had problems with libc6 programs
and locale settings, please try this and get back to me whether this
helped.

Re: Debian target audience
Alex Yukhimets [EMAIL PROTECTED] writes: The problem of having both libc5 and libc6 run-time libraries is minor, the main one is that those stuck with libc5-dev cannot use other newly-available versions of *libraries* from hamm. How do you mean? You can install the *libraries* just fine, it's just the development versions that fail to install. That's exactly what I meant, sorry if it wasn't clear. And even then, why not install lib5-altdev? Then there is no problem whatsoever. I am sorry to say, but you are wrong. Even on this list there were several postings regarding this matter. There are several known problems and who knows how many unknown. You just can't afford to experiment with production system this way. Anyway, I could take some burden on myself to compile libc5 counterparts, but on my 486DX2/66 with 2k/sec connection it would take years. Nearly all of the problems mentioned here are _not_ problems with the -altdev packages but with the transition period while not all packages use this standard. There is a single problem with utmp, that will cause buggy (!) programs to have problems, i.e. programs that do _not_ use the C library functions to access utmp. Other than that there was the locale problem that has been fixed (at least for me) using libc 5.4.33 and glibc 2.0.4. For me these are not enough reasons to support a stable tree for libc5-only when we have fixed our transition problems fro hamm. Furthermore it is _far_ too early to talk about what we'll be doing when hamm is released as we first have to see how many problems there will be with a hamm system (currently there are next to no packages using the hamm conventions).

locale errors found fixed
Well, open mouth extract foot,.. When doing a complete reinstall of all involved packages, I finally found out that I had a messed up locale directory. So everything would work for me, but not for anyone else :( So here's the problem: libc6 and libc5 use different magic numbers for their locale files. These are defined in locale/localeinfo.h in the libc source tree: in libc5: #define LIMAGIC(category) (0x960316de ^ (category)) in libc6: #define LIMAGIC(category) (0x960617de ^ (category)) So of course it couldn't work.

According to the linuxthreads FAQ no distribution currently supports reentrant libraries ( Xlib is very critical about that ) The linuxthreads package is part of the libc6 packages, as it is an add-on to glibc 2. As the new libraray handles threads much better than libc5, you should base all work intended to do threading on libc6. Our aim for Debian 2.0 is to provide all libs as reentrant. It usually isn't enough just to compile it with -D_REENTRANT. You have to avoid static and global variables and do some mutex locking. XFree86 3.3. supports reentrant libraries when based on libc6.

RFC: libc6 policy supplement 2nd try
Here is a reworked proposal:
-=-=-=-=-=-=-=-=-=-=-= SNIP -=-=-=-=-=-=-=-=-=-=-=-=-=-
Debian library policy supplement draft for libc5-libc6 migration
This document is meant to tell what a Debian package providing a
library should do to support both libc6 (glibc2) and libc5.
Note that these requirements are for Debian 2.0 (codename hamm).
Contents
1. Run time packages
2. Development packages
3. Requirements on libraries for Debian 2.0
4. Requirements on compiler packages
1. Run time packages
A package providing a shared library has to support both C library
packages, libc5 and libc6 based libraries. This must be done using
two Debian packages, each depending on the correct C library
package.
The package naming convention currently suggests to name these
packages as follows [1]. Some packages (mostly from base) may use
locations in /lib.
based on | package name | library location
libc6 | libfoo | /usr/lib/libfoo.so.ver
libc5 | libfoo-g | /usr/lib/libc5-compat/libfoo.so.ver [2]
If a library runtime package contains files that are needed by
both versions of the library, a new package should be made for
just these files that both other packages depend on.
This package naming convention does _not_ apply if a package uses
different sonames for libc5 and libc6 based packages
There are two exceptions from this rule. The shared linker
ld-linux.so.1 and the C library files libc.so.5 and libm.so.5
should still be located in /lib, not in /lib/libc5-compat.
Packages based on X have to use /usr/X11R6 as prefix, not /usr.
Note that the X libraries are designed to work with both C libraries.
2. Development packages
The Debian policy requires that all files needed for compiling/linking
other packages with the library are in a separate package, the
development package. Up to now this package simply was called
libfoo-dev. As packages based on libc5 and libc6 usually cannot
use the same development files there has to be a clear statement
how to separate these. So for now the following packages are
required:
based on | package name| hierarchy locations
---
libc6 | libfoo-dev | /usr/{lib,include}
libc5 | libfoo-g-altdev | /usr/i486-linuxlibc1/{lib,include}
Note that the choice to base Debian 2.0 on libc6 fixed the fact
that the main locations will be used for libc6 packages. The
alternate locations are used for libc5 based packages.
This decision does not necessarily mean that by default the
compiler uses the libc6 packages, please read section 4 for more
information. Using a four-way approach for library locations
(standard and alternate locations for libc6 and libc5 based
packages) will make Debian systems inconsistent with each other,
something we should avoid at (nearly) all costs.
3. Requirements on libraries for Debian 2.0
Libraries (regardless of which library they're compiled against) need
to have runtime dependencies on one of libc, libdl or libm to enable
the shared linker to determin which library to use for a binary.
In general we want libraries compiled for libc6 to be thread-safe.
This means that the following changes must be made to the library
packages:
- compile the library using -D_RENTRANT or -D_THREAD_SAFE
- there may be no permanent data residing in the library memory that
can be different for different threads.
this means in the first place no static or global variables that
are not in some way protected from access by a different threads.
- all write access to files from a library must be both protected
using some file locking mechanism in addition to using mutexes.
- library functions must be protected from being used at the same
time by two threads sharing the same memory space. This is done
using mutexes.
As these usually are all nontrivial changes to a library if it isn't
thread-safe already (in which case just using -D_RENTRANT should
be used in addition to whatever the library uses to support threads),
I suggest that noone starts doing this without getting in contact with
the upstream maintainer(s).
There will be a list available that lists all libraries part of
Debian and their current status regarding compliance with these
standard requirements. This list will be posted regularly to
debian-devel by Helmut Geyer [EMAIL PROTECTED].
4. Requirements on compiler packages
The compiler and binutils packages have to provide working
development environments for both C libraries. Basically (that is
from the compiler standpoint) there is no real difference between
the two environments, only some paths

This file is read by all libc5 programs before /etc/localtime. removing it should make 822-date work again. I'll check for this file in the next package and remove it, if present.

Re: libc6
On Jun 11, Guy Maor wrote I'm working on the xdaliclock package, and I will take it to libc6. I have merely recompiled it, and all has worked fine, except perhaps some warning (perhaps present with libc5: I have not installed alt-libc5 as yet). This is suspect to me, because my X libs are compiled with libc5, and in this list I've read that ncurses (simpler than X libs) give problems with libc6 in compile time. Perhaps I'dont have understand well the problem: can you explain it to me? Maybe I misunderstand, but it sounds like you're trying to compile a binary against libc5 versions of some libraries and libc6 versions of others. That will never work. No. The surprising thing is that it _does_ work. (e.g. take the DDD source in a libc6 environment, with libc6 libg++272, libc5 ncurses, X etc. It compiles and works). The problem is that there could be subtle problems from the interaction between libc5 and libc6 libraries, which may be very difficult to track. This means that maintainers who work in a libc6 environment must check very carefully that all the libraries they link against are really for use with libc6. H.J. Lu and the XFree86 team did a lot of work to make this work. whether it works perfectly, I don't know but as X uses its own datatypes for most things one of the main problems of incompatibility between libc5 and libc6 is not present.

Re: problem with /proc info
I'm sorry this wasn't meant to go to the list. The main point was that MemShared is counting the amount of memory spared by the use of shared pages, not the number of pages with a reference count greater than 1 (which corresponds to the physical memory/swap occupied by shared pages).

Re: libc6 utmp and wtmp [Was: Re: official C library]
Miquel van Smoorenburg: In article [EMAIL PROTECTED], Johnie Ingram [EMAIL PROTECTED] wrote: Am I correct in thinking the major players to be synchronized here are shellutils (who), sysvinit (last), netstd (rsh), login, ppp, procps, wu-ftpd, and ssh? Well, if the program that uses utmp is wellbehaved and uses getutent() and friends, we could put a libc6-utmp emulation in libc5. Then you just let libc6 conflict with libc5 = 5.4.23-6 so that installing libc6 forces an install of a libc5 with the emulation layer. There are some programs though that read/write utmp not using the library interface. Usually you can find them by running strings on the program and checking for /var/run/utmp. I don't know what to do about those, but they should be fixed for libc6 anyway so maybe we can fix them, recompile for libc5 and put them in Debian-1.3.x. The programs that write to utmp are the worst, those are probably just getty, in.rlogind, in.telnetd, pppd, sshd, rxvt, sessreg [..] Well I have done a utmp wrapper for libc5 and am currently testing it. I was very reluctant to release it without heavy testing to unstable but it should appear this weekend on master. This changes the libc utmp functions. glibc 2.1.x will have a utmp daemon that monitors accesses to utmp and serves both old and new utmp formats. Until then we have to be careful of those bad behaved programs that access utmp directly. BTW, the same is true for lastlog but wihtout the benefit of existing libc functinos to access it. Please take a look at my release notice when they're available.

top and window resizing

Re: ncurses libc6
I was thinking about building ncurses 4.1 with libc6 when I saw this file : README.glibc To compile this as an add-on for glibc, unpack it in the glibc source tree and put ncurses on the add-on list when you do configure. [EMAIL PROTECTED] 03/21/1997 So it seems possible to compile libc6 and ncurses as a whole. As libncurses is outdated and needs to be recompiled for libc6 why not use this possibility ? David what do you think about this ? Note : please CC mails about this to me, I'm not subscribed to the list. Hello, I'm the new libc5 libc6 maintainer. It is possible to include ncurses in the libc6 packages, but it is not much easier to compile using the glibc source tree than doing without. I contacted the ncurses maintainer, Michael Alan Dorman, last weekend and he promised to have a new package out RSN.

RFC: policy supplement for library packages
Hi Folks!
The late discussion here on migration to libc6 indicates that a
statement on the requirements of library run time and development
packages is to be included in the policy manual. This is how I recall
the discussion we had about this topic some weeks ago. It might be
that I am a little biased, so feel free to correct me if you recall it
differently. Neither is this meant to be a fixed thing but we
definitely _need_ something so I started writing.
As I am taking over libc5 and libc6 from David Engel I will be heavily
involved in this anyway.
Helmut

Debian library policy supplement draft for libc5-libc6 migration
This document is meant to tell what a Debian package providing a
library should do to support both libc6 (glibc2) and libc5.
Note that these requirements are for Debian 2.0 (codename hamm).
Contents
1. Run time packages
2. Development packages
3. Requirements on libraries for Debian 2.0
4. Requirements on compiler packages
1. Run time packages
A package providing a shared library has to support both C library
packages, libc5 and libc6 based libraries. This must be done using
two Debian packages, each depending on the correct C library
package.
The package naming convention currently suggests to name these
packages as follows. Some packages (mostly from base) may use
locations in /lib.
based on | package name | library location
libc6 | libfoo | /usr/lib/libfoo.so.ver
libc5 | libfoo-libc5 | /usr/lib/libc5-compat/libfoo.so.ver
If a library runtime package contains files that are needed by
both versions of the library, a new package should be made for
just these files that both other packages depend on.
There are two exceptions from this rule. The shared linker
ld-linux.so.1 and the C library files libc.so.5 and libm.so.5
should still be located in /lib, not in /lib/libc5-compat.
Packages based on X have to use /usr/X11R6 as prefix, not /usr.
2. Development packages
The Debian policy requires that all files needed for compiling/linking
other packages with the library are in a separate package, the
development package. Up to now this package simply was called
libfoo-dev. As packages based on libc5 and libc6 usually cannot
use the same development files there has to be a clear statement
how to separate these. So for now the following packages are
required:
based on | package name| hierarchy locations
---
libc6 | libfoo-dev | /usr/{lib,include}
libc5 | libfoo-libc5-altdev | /usr/i486-linuxlibc1/{lib,include}
For the transition time there may be packages based on libc5 which
use the standard location. These have to conflict with libc6-dev,
however.
libc5 | libfoo-libc5-dev| /usr/{lib,include}
No such packages may be part of Debian 2.0.
Note that the choice to base Debian 2.0 on libc6 fixed the fact
that the main locations will be used for libc6 packages. The
alternate locations are used for libc5 based packages.
This decision does not necessarily mean that by default the
compiler uses the libc6 packages, please read section 4 for more
information. Using a four-way approach for library locations
(standard and alternate locations for libc6 and libc5 based
packages) will make Debian systems inconsistent with each other,
something we should avoid at (nearly) all costs.
3. Requirements on libraries for Debian 2.0
this needs work still, here some keywords make libraries
thread-safe,
There will be a list available that lists all libraries part of
Debian and their current status regarding compliance with these
standard requirements. This list will be posted regularly to
debian-devel by Helmut Geyer [EMAIL PROTECTED].
4. Requirements on compiler packages
The compiler and binutil packages have to provide working
development environments for both C libraries. Basically (that is
from the compiler standpoint) there is no real difference between
the two environments, only some paths and automatic definitions
have to be changed. All this can be done (and is in fact done) by
supplying a different specs file in a different location.
The compiler package has to supply a way to make one of the two
environments the default one.
Two ways this can be done are:
- using /usr/i486-linuxlibc1/bin for the libc5 based gcc. Just by
prepending this to the path this can be made the default.
This is the standard way such things are handled for
cross-compilers but has the disadvantage that each user has to
do this in order to make this change. As this has better
flexibility
Re: Bug#4261: Ghostview and virtual package postscript_viewer
Package: ghostview Version: 1.5-8 Ghostview should install itself into the /etc/mailcap entry so mime compatible programs can use it to view postscript documents. I suggest making ghostview Recommends: mime-support and adding the following to the install scripts: debian.postinst ~~~ if [ -x /usr/sbin/install-mime ] then install-mime--install --package=ghostview --content=application/postscript \ --description=Postscript Formatted Output --nametemplate=%s.ps \ --test='test $DISPLAY != ' \ --view='/usr/bin/X11/ghostview %s' \ --comment=Ghostview is a fairly good front-end for viewing postscript \ and should probably be given a reasonably high priority. fi debian.prerm if [ -x /usr/sbin/install-mime ] then install-mime --remove --package=ghostview fi No, that isn't what should be done, or at least not the only thing. I'm on my way to produce a second posctscript-viewer (front-end to gs) called gv, that is in some ways much better than ghostview, though there are too many differences in the user interface to drop ghostview instead. I propose to have a virtual package postscript_viewer installing a /etc/alternatives - managed binary /usr/bin/X11/ps_view and handling the stuff via update-alternatives. mime-support should either put/usr/bin/X11/ps_view into mailcap by default (which is what I propose), or we install it from ghostview and gv using install-mime.

beware sysvinit 2.58 installation
Hi! There is a small problem with the new sysvinit (2.58-1) suite. Once you have installed it, you can't shutdown/reboot/halt the system as these use a different way of communicating than the 2.57* init (a FIFO, no longer a file). So please make copies of the old init,shutdown, halt and reboot programs and reboot right after installing sysvinit 2.58. After rebooting, you can delete the old files.
