No, this isn't enough. I want an stable method which never leaves the system in an inconsistent state. When revdep-rebuild is required, there's normally a period of time where some installed packages are broken (okay, preserved-libs makes it better), exactly what I never want on a productive system. I personally wouldn't want to automate this. The problem is that different virtuals need different switching strategies. Converting from jpeg to jpeg-turbo is relatively straight-forward. Switching between httpd-basic implementations, on the other hand, needs manual work to carry over config files and such. I didn't intend to do this fully automatic, for all virtuals. Just a bunch of special ones which just handle the scenarios of exchanging libraries (also on different/incompatible ABIs). Maybe it would be a better idea to teach emerge to warn the user when a default virtual implementation is about to be installed and show the different alternatives. Similarly emerge --sync or eix-sync could inform the user when a new alternative package for an already installed virtual is available. Indeed, that would be a good feature. Isn't that problem resolved in portage-2.2 by keeping the old library file around until all packages have been re-emerged? The preserve-libs stuff ? I'm not sure how it actually works under the hood, but as far as I can see it, it's just done for certain critical libs yet (eg. openssl), and the package manager doesn't know much of it, just keeps certain files around. So manual revdep-rebuild runs and removals of old libs is still required. cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weig...@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --
[gentoo-user] eselect for managing virtuals
Hi folks, just an idea spinning around in my head: Is it possible to influence the dependency resolution (eg. on virtuals) ? For example, several weeks ago somebody here asked on how to switch from jpeg to jpeg-turbo. For such cases it IMHO would be fine if there was some eselect which controls the behaviour of the virtual/jpeg package. Once he switched over via eselect, it would trigger the other jpeg implementation and (if necessary) rebuild of all depending packages on next emerge world. Could the current eselect + portage system provide this ? The whole idea could also be extended to packages which frequently require revdep-rebuild (eg. poppler): those packages would be slotted for parallel installation and an new virtual is introduced where clients will depend on (instead of the actual package directly) When new versions come out, the user will be tolld (eg. via eselect news) that he can now switch his system. Once he does the switch, new builds will be made against the new version and remaining packages (still linking to the old library) will be triggered for update. cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weig...@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --

Re: [gentoo-user] The CHOST variable
* Nils Holland n...@tisys.org wrote: 1) So a package using the GNU build system determines or is passed (via --host aka. CHOST) a target triplet specifying the system on which the resulting compiled code is supposed to run. What does the package do with that information? Does it only use it to determine what it has to compile (different / special code for different systems / architectures), or does this already have an influence on the optimization of the resulting code for a certain (sub-)architecture? Exactly. Some packages have arch- and subarch-specific optimizations. Those things IMHO should be primarily taken from the target triplet (instead of other ./configure options), as it quite exactly defines what cputype, platform and toolchain type you're using. It's very important for crosscompiling (even some toolchains, eg. gcc., could, and should, be explicitly asked for their target triplet). Forthermore: Does configuring a package with, say, --host=i686-pc-linux-gnu already automatically mean that said package would not be able to run on (for example) an i486-pc-linux-gnu host? Maybe. Or maybe it's just quite slow, eg. when it's using certain opcodes that are not supported by the older subarch and handled by the kernel via exceptions (back in i386 times, that was the case for fpops, when no fpu was present). It all depends on how the individual package is actually coded. 2) /etc/make.conf contains a note that one should not change the CHOST lightly (not that I'm planning to) and links to a nice document explaining how it can be done anyway (which, I have to admit, didn't make me any wiser, however). The question is, out of curiosity, why the CHOST should not be changed and what would happen if one did it anyway. I willingly believe that it would lead to problems, but would the actual cause of these problems actually be caused by the configuration of the machine being mixed up (for example, by the GNU build system / autoconf suddenly looking for a compiler or similiar tools / libraries under a path or by a name involving, for example, i486-pc-linux-gnu, which does not automatically exist of the appropriate tools have not been installed accordingly. Or would problems arise because code generated with the new CHOST does no longer fit to code generated with the previous / old CHOST? One of the most evil things that can happen (also w/ certain optimization flags) is a mismatching calling convention between certain libraries and executables. For example, code built for a newer subarch could put more call arguments into registers which the called functions dont expect - stack corruptions will happen. cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weig...@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --
Re: [gentoo-user] The CHOST variable
* Nils Holland n...@tisys.org wrote:
The question is, I guess, if the target host, when of the same arch (i.e.
i[3456]86) does actually have any influence on the code that gets
generated in terms of performance or ability to run on other sub-arches.
This is what I really couldn't find out so far and would find highly
interesting to know.
Yes, both. Passing arguments via register (instead of stack) can be
much faster in some cases, especially when you have a lot of calls
with small parameter sets, eg:
libfoo.c:
int foo(int a, int b)
{
... do-something ...
}
progbar.c:
int main()
{
...
for (int x=0; x1; x++)
foo(x, wurst);
...
}
On older subarchs, main() will have to push x and wurst on stack for
_each_ call, and foo() has to pop them down. With a newer subarch that
has more usable registers, the parameters a and b can directly sit in
registers (probably the counting of x might already happen in the same
one), so the parameters dont have to go through the stack. That all
heavily depends on the target ABI.
For example, why not just go (and stay) with CHOST=i386-pc-linux-gnu and
on an i686 machine, set march or mcpu = i686 via CFLAGS if you want to
optimize for the particular subarch at hand? Why should it be necessary /
what would the (dis)advantages be of of such a setup vs. also having CHOST
set to i686-pc-linux-gnu?
I'm not sure right now if/how -march and -mcpu affect calling convention,
variable alignments, etc (IMHO -march does, while -mcpu doesn't), but
as soon as you change these ABI elements, it can get really dangerous.
Concering the Gentoo doc about changing the CHOST that was mentioned: Yep,
I've read that. If I understood it correctly, problems when changing CHOST
mainly seem to arise because of the way GCC and related basic build utils
install themselves (using the host triplet as part of their path or
executable name), leaving wrong / messed up references when changing the
CHOST.
You're lucky if the compiler fails early this way, so you don't have
the unpleasant experience of sudden runtime breakages ;-p
For example, as I've said previously, the CHOST value gets passed to
./configure as --host for each package that gets build. That would make
configure try to select a compiler called CHOST-gcc in order to compile
... if the toolchain commands aren't passed explicitly ...
(which you *SHOULD* do in any crosscompiling scenario)
the package, i.e. when CHOST is i486-pc-linux-gnu, a compiler called
i486-pc-linux-gnu-gcc would be used. Include file directories for glibc
and / or glibc itself sems to be selected by a similiar mechanism.
AFAIK they're not selected by this parameter (even some illdesigned
configure script might do such crazy things on its own ;-o), but built
into the toolchain commands themselves. You can override/change them,
but then you really should know what you're doing ;-p
The Gentoo CHOST document that was mentioned says something about nptl not
being available on i386. If true, and if the host variable generally
influences the availability of features, things would slowly start to make
sens as to why the CHOST might be important.
Exactly. nptl vs. linuxthreads is exactly an good example for
incompatible ABIs (while API more or less stays the same).
On the other hand, I've read
through some documentation of the GNU C library (glibc) and didn't even
find anything about nptl not being available on i386, not to mention
anything else about different features on different subarches.
I don't know much about their internals, but I can easily imagine
that nptl makes heavy use of newer registers which linuxthreads didn't.
For those things you should ask the gcc and libc folks.

[gentoo-user] Paper: Normalized source code repositories
Hi folks, some while ago I've already talked a bit about the OSS-QM project and it's source code repositories, which include upstreams together with downstream's (distros, etc) changes. Here's a paper describing it more in datail, from automated upstream imports down to also importing downstream/distro changes automatically. The latter works quite well for recent Debian packages (at least when following their own policies ;-o), as they tell quite exactly which patches have to be applied (and their order). For Gentoo it's more complicated, as I dont know a way to exact that information yet. http://www.metux.de/download/oss-qm/normalized_repository.pdf cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weig...@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --

OSS-QM makes sharing and automatic notification on new patches easier. In this sense they are the propriatary work and the capital of each distro. So I guess it will be difficult to convince them to store their patches into a common QM repository. That's why I'm working on automatic imports. For Debian packages (at least those complying the recent guidelines) it's almost done (for now just for a few packages as proof-of-concept, but can be made more generic). Gentoo is a bit trickier, since patching is called explicitly from each ebuild (sometimes even useflag-dependent). The Gentoo devs could help a great deal if they would set a policy like: * all patches have to be normalized (eg. *always* apply w/ -p1) * a easily machine-readable (eg. via grep+sed ;-o) list of patches to apply on a specific version (eg. in the ebuild or a separate file) * make the patches independent from useflags * do sourcetree changes _exclusively_ via patches (no file copy-in's or directly changing files w/ sed etc) That's true as far as we speak of unixoid environments. To port programs to other environments requires more efforts than just a proper build system. Yes. The individual package has to sit ontop of properly defined interfaces (eg. POSIX), and require the target to provide that (if it doesn't, fix the target's system libs, toolchain, etc). The original idea of Java was, to bring a standard layer into any environment, that would remove the need of ports. Yes, but that's a matter of the basic class libraries, not the language. The same can also be done in plain C. The interesting point in Java is that it is an (well, was) an very cleanly defined virtual machine (even virtual processor) One interesting point is, that it is was very successfull, but on completly different fields than origninally targeted. Most Java doesn't run platform independent programs, but runs servers, that don't need to be platform independent at all. Well, that's a quite strange effect. IMHO that doesnt have anything to do w/ the platform agnosticism, but the language concepts which might be better suited for those applications. Java was also designed to facilitate programming comparing C. Still Java itself isn't the last clue. Take the horrible way to copy a simple array. Yes, there're also other concepts I miss in Java, eg. native associative arrays, language constructs for parallelisms, etc. Briegel is strongly focused on the technolgical basics, without talking of all possible usecases.

Re: [gentoo-user] Re: Shared libraries in Gentoo
* Al oss.el...@googlemail.com wrote: While porting to cygwin I can be happy when they use it. For my first impression those libraries are more easy to port. They produce libraries with a *.dll.a suffix like the native libraries of Cygwin. Just a few years ago, autotools (especially w/ libtool) was totally unusable for any kind of isolated (not just crosscompiling), based on completely stupid assumptions and practically undebuggable. All the functionality could be easily done w/ shell functions instead of syntactically unstable m4 macros. I've started a little bit of hacking @ zlib (see oss-qm repo) how that could look like. The other example is libz. AFAIK it has a manually written configure script. It generates libz.so. bzip2 ends up in error messages until I build it statically. AFAIK zlib properly builds shared library as well as static one (at least on unixoid targets). Win32 targets are still a bit messy, but there's work ongoing on that. I still try to understand the relation of shared libraries and dynamic libraries. I read that dynamic libraries are linked at runtime. I also read, that you can dynamically link againgst a shared as well as against a normal library. But isn't a normal library also shared when multiple programs link it at runtime or does shared library mean it is shared in memory (PIC)? Well, static libraries are essentially an archive of plain object files (maybe with an additional symbol table for faster lookup). They essentially get linked in at build time just like plain objects. Shared libraries are different: they really get linked together, certain sections (especially symbol tables) are merged, local references resolved. An shared library actually is one big object file (that's why they're also called shared object). Now these objects are loaded and linked-in at the process startup phase (or later using dlopen()). At this point, shared means that multiple programs can use the very same code from one shared object file. Another level of sharing is at runtime, by using shared pages by the MMU. This is a bit more complex: you need to construct the binary code in a way that multiple processes can map it into separate address offsets (historical systems require the addresses to be defined at compile time, which obviously is impractical). At that point -fPIC comes into play: the code is generated in a way that it's position in process's address space doesnt matter anymore (at least on page-granularity). So calling processes can directly map the shared object's text segments into quite arbitraty offsets without touching the actual code pages, and the MMU only has to maintain one physical copy of them. PIC tends to be a little bit larger and slower than non-PIC (more indirect addressing), but on most today's machines the impact on real workloads is questionable. cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weig...@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --

Having different levels of abstraction is fine, but they should do it in clean way without mixing levels at least. Yes. And truely, some ebuilds do things they IMHO shouldnt do. For example, ebuilds should _never_ change source trees arbitrarily, instead just have a defined set of patches (independent from useflags) against the original sourcetree. But that's a problem of some individual ebuilds, not emerge in general. It's clear that the overall package management is a different layer from program building. However the question of portablility for example is mixed into all levels, is it libtool or is it eclasses. It will be similar for things like internationalization. Most of these issues should _not_ be mixed onto several layers, that's one of the major problems, upstream's misdesign, tolerated by downstreams/distros ;-P Ideally it can. In praxis the stack can't always be coped layer-by-layer by different teams. In the moment the bug is there, you have to search them all. You just need access to all layers and test from buttom up. For my target of a port I have to understand them all, up to a certain degree. I have to apply patches at different layers. There should only be exactly _one_ place for applying patches: a QM layer in the middle between upstream release and distro's package management. And now we're at the OSS-QM project again ;-p For my case that would be of help. I currently have to mix patches from cygwin with patches from Gentoo. Sure that leads to conflicts. The problem here is that there's now common QM layer of Gentoo *and* Cygwin (and other distros), between upstream and distros. And here we see a typical problem: individual distros tend to do only distro-specific patches, which often are not upstream-capable, instead of _generic_ fixes. Again: OSS-QM ;-p However it is always problematic to depend on another team and have to wait for bugfixes. You must be able to bugfix yourself. Is that addressed by the oss-qm?

Re: [gentoo-user] Re: emerge 32bits on 64bits platform
* Nikos Chantziaras rea...@arcor.de wrote: Welcome to hell. No, that's possible, as others pointed out. There was an initiative to bring true multilib to Gentoo a year or so back (maybe more) but it seems it died and no one's working on it. For your browser this is probably not so problematic. But imagine someone running the latest graphics stack (libdrm, mesa, etc.) on his 64bit machine, but its totally useless because proprietary Linux games are 32bit and thus won't run. The problem here is that this essentially means having two systems in one, 32bit and a 64bit one. To make it really clean, we'd actually need two separate installations (eg. using jails). But that makes administration quite complex. Perhaps portage could be extended to support a concept of subsystems, which are fully self-conftained for the runtime stuff only (but no portage, toolchains, etc). Everything that's not required for booting and building (so, the essential base-packages) is now sitting within a subsystem (maybe that's even a jail). Each subsystem of course also has its own /var/db/pkg etc (maybe even own /etc/portage stuff). Portage would now compute an internal portage tree for all subsystems using namespaces. The actual build then runs in an sysroot environment for the actual subsystem. Let's take an example: mc On an fresh system, `emerge -peqt app-misc/mc` looks like this: [ebuild N] app-misc/mc-4.7.0.3 USE=edit gpm -X -nls -samba -slang [ebuild N] sys-libs/gpm-1.20.5 USE=(-selinux) [ebuild N] app-arch/xz-utils-4.999.9_beta USE=threads -nls -static-libs [ebuild N] dev-libs/glib-2.24.1-r1 USE=-debug -doc -fam -hardened (-selinux) -xattr [ebuild N] sys-devel/gettext-0.17-r1 USE=-acl -doc -emacs -nls -nocxx -openmp [ebuild N] dev-util/gtk-doc-am-1.15 [ebuild N]app-text/docbook-xml-dtd-4.3-r1 [ebuild N]dev-libs/libxslt-1.1.26 USE=-crypt -debug -python [ebuild N] dev-libs/libxml2-2.7.7 USE=-debug -doc -examples -ipv6 -python -readline -test [nomerge ] app-text/docbook-xml-dtd-4.3-r1 [ebuild N] app-text/sgml-common-0.6.3-r5 [ebuild N] app-arch/unzip-6.0-r1 USE=bzip2 -unicode [nomerge ] app-misc/mc-4.7.0.3 USE=edit gpm -X -nls -samba -slang [ebuild N] dev-util/pkgconfig-0.25-r2 USE=-hardened [nomerge ] app-text/docbook-xml-dtd-4.3-r1 [ebuild N] app-text/docbook-xsl-stylesheets-1.75.2 [ebuild N] app-text/build-docbook-catalog-1.4 Now on the new model it would be: `emerge -peqt x86_32::app-misc/mc` [ebuild N] x86_32::app-misc/mc-4.7.0.3 USE=edit gpm -X -nls -samba -slang [ebuild N] x86_32::sys-libs/gpm-1.20.5 USE=(-selinux) [ebuild N] main::app-arch/xz-utils-4.999.9_beta USE=threads -nls -static-libs [ebuild N] x86_32::dev-libs/glib-2.24.1-r1 USE=-debug -doc -fam -hardened (-selinux) -xattr [ebuild N] main::sys-devel/gettext-0.17-r1 USE=-acl -doc -emacs -nls -nocxx -openmp [ebuild N] x86_32::sys-devel/gettext-0.17-r1 USE=-acl -doc -emacs -nls -nocxx -openmp [ebuild N] x86_32::dev-util/gtk-doc-am-1.15 [ebuild N]main::app-text/docbook-xml-dtd-4.3-r1 [ebuild N]x86_32::dev-libs/libxslt-1.1.26 USE=-crypt -debug -python [ebuild N] x86_32::dev-libs/libxml2-2.7.7 USE=-debug -doc -examples -ipv6 -python -readline -test [nomerge ] main::app-text/docbook-xml-dtd-4.3-r1 [ebuild N] main::app-text/sgml-common-0.6.3-r5 [ebuild N] main::app-arch/unzip-6.0-r1 USE=bzip2 -unicode [nomerge ] x86_32::app-misc/mc-4.7.0.3 USE=edit gpm -X -nls -samba -slang [ebuild N] main::dev-util/pkgconfig-0.25-r2 USE=-hardened [nomerge ] main::app-text/docbook-xml-dtd-4.3-r1 [ebuild N] main::app-text/docbook-xsl-stylesheets-1.75.2 [ebuild N] main::app-text/build-docbook-catalog-1.4 Note that here portage into which subsystem a package has to go in.

Now I have two main questions in mind: what to and how to back up on gentoo most efficiently. I'm using a little script like that: #!/bin/bash cd /var/backup/blackwidow || exit 1 DATE=`date +%F-%H-%M-%S` rsync --exclude-from /scr/etc/backup-blackwidow.exclude \ -avz blackwidow:/ /var/backup/blackwidow/ROOT \ --backup \ --backup-dir=/var/backup/blackwidow/BACKUP-$DATE\ --delete \ --delete-excluded \ --delay-updates \ --progress\ (of course with a carefully maintained exclude file ;-p) This doesnt make a real rotating backup, but stores all files that get overwritten into their own directory (named by the current date). And from time to time, I'm cleaning up the backup volume and look for things that I still might need. For things I'd like to keep an history (eg. /etc) I'm using git, and pushing the repo to a remote server (denying non-fastfoward updates there, so an theorectical highjacker cannot destroy my history) For really long-term backups with bigger content (that might be too big for git), you could also give venti+vac (from plan9port) a try. I'm using it for storing larger media files (videos, etc) in my MediaCloud platform. 1. Apart from users' home directories and the followings, what should be backed up on a gentoo machine? /etc/portage/ /root /var/lib/portage ...? Depends on how long the recovery may take. For example, if you can afford recompiling world (or have another compatible image somewhere else), you can exclude everything where packages are installed (bindirs, libdirs, /usr/share, etc, etc) - assuming everything's installed by portage. Though I can find enough space on the external drives, I don't trust them any more. See above..sigh..(No I recovered about one third of it with testdisk/photorec which names them as file01 file2.. and half them are zero sized.. which quite justifies my agony) Make multiple copies on different media (eg. different servers). cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weig...@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --

[gentoo-user] automatic wlan restart
Hi folks, I'm regularily loosing wlan link (not sure if its a driver problem or disortion in the local air) and so have to restart the wland interface quite often. As the box is also doing several automatic things (backups, etc), it's really ugly (eg. when I'm not on keys, at some point no backups can be made, etc). So I'm looking for a way to fully-automatically restart the interface when the link goes down. Of course, I could hack up some syslog parsing, which calls '/etc/init.d/net.wlan0 restart', but that implies the interface going down (iow: ipstack will report no route to destination network back to applications) for several seconds.

[gentoo-user] zlib ebuild from OSS-QM
Hi folks,
here's an ebuild for zlib, which takes a fixed source from the
oss-qm project. it contains several fixes and cleans up ugly
hacks in the current ebuild (eg. directly sed'ing sources ;-o).
please refer my recent postings on details what the oss-qm
project is all about. just a few words: the main idea is to
solve problems at the source, provide generic downstream
branches (which get rebased onto upstream) instead of single
(often unncessarily distro-bound) patches.

Re: [gentoo-user] Safe to install libpng-1.2.44?
Hi folks, big_snip / I think the libpng issue shows up a more generic problem: we IMHO dont have a way for recording, which version / interface of some version a package is built against. The need for things like revdep-rebuild also comes from that. I'm currently working on an generic design for that, some ideas: (of course, yet limited to C and similar languages ;-o) * libraries with (incompatible) interface changes should install their headers under some own versioned prefix * library imports should _always_ happen via pkg-config (dont use .la files) * pkg-config descriptors are extended to declare the API and ABI version and generation, so interface breaks can be determined automatically * the package management records which version of some imported library a package was built against (some kind of revdep-scan between compile and merge) * with that information the package management can do an smooth upgrade (w/o temporary breaks until revdep-rebuild finished) cu -- - Enrico Weigelt== metux IT service - http://www.metux.de/ - Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ -

In case of some depenency exists in different slots, the installed binary package record also contains a dependency to the lib's slot the package was actually built against. This way, old versions/slots still in use should never be uninstalled.

[gentoo-user] Rethinking binfmts [WAS: How the HAL are you supposed to use these files?]
Alan McKinnon wrote: Why is ELF so prone to bloat (or more accurately why do so many compilers generate such large libs?) Yes, that's an really good question. ELF has many things, that are IMHO not really necessary or shouldn't even be used. For example, debugging information doesnt need to exist within the binary itself. An external file would be fine, too, and allows removing them by standard file operations. Another redundant thing is exec()'ing the dynamic linker from userland: the kernel could load it along with the usual segments. There could even be a default kernel-land dynamic linker (for the 99.9% cases where no special linker is needed), it could cache a lot of stuff. If I were to design a new binfmt, it would look like this: * Magic + file size + file hash * userland linker filename (may be empty) * 4x segment descriptor: - packed-size, real-size, offset, encoding (compression,etc) - #0: code, #1: data, #2: symbol table, #3: unused * imports-list: virtual library name + namespace-id * entry point (relative to code segment) * symbol table (possibly compressed) * [.. segment data ..] ...

That's the job of the distro buildsystem. Ah, and that dramatically minimizes the chance that things break apart (i still remember the old times when libc updates tended to be dangerous). and even better - just introduce a single patch/updated package and everything is fine. What you are describing is maybe nice with gentoo. But a nightmare if you want something stable. Recompiling everything is not an option. hmm, you consider Gentoo unstable ? ;-o Why do you think the whole industry went away from static - except for tiny embedded devices? Is that so ? Then, why are so many closed-source applications statically linked ? no, under the axiom of sharable code. The size of a lib is not really important - except if you use everything. But if you compile in everything the lib does on a static basis, all your binaries are huge and bloated. Yes, lazy page-loading, any maybe even lazy evaluation (uuh, tricky!), but this also comes with costs. Rethink the idea of tiny libraries: there's much more that can be reused. There're always not just reasons for choosing some particular library, but also ones for NOT choosing it. For example, imagine some app where a few of glib's functions would be useful, but there're other big arguments against it (eg. resource consumption, unstable API, etc). So we have to find that stuff we could have used somewhere else, or write it on our own. The major problem w/ these big libraries is that they're highly redundant from a function viewpoint. Why do we need dozens of libraries which all define such common ADTs like linked-lists, polygons, etc, etc, etc on their own ? Why can't they just all reuse other, small libraries ? At this point, I'm very much a Prof.Wirth's side: have one module per ADT, which only does that thing right, but nothing more. Don't forget that this is far beyond runtime memory consumtion. Memory is quite cheap today. But developer's manpower is not. When I review all the OSS projects (yes, commercial ones tend to be even worse) I've been involved in the last 15 years, I'd count at least 30% is completely redundant, completely useless spent resources. Just because bad design decisions. Just ask around the gentoo-devs how much time they spent into things like slotting, complex dependencies (conflicts, circular deps, ...), etc, etc. that's all caused by reallybad design decisions coming from the upstream.

Re: [gentoo-user] How the HAL are you supposed to use these files?
Mike Edenfield wrote: Just for reference, 9p is not Plan 9, it's only the Plan 9 network protocol/distributed file system, which you can use on Linux with the appropriate file system modules. Right. Either you use the kernel module (which now is in mainline for quite a long time), or 9pfuse, or one of the userland libraries around (eg. libmvfs). The basic idea behind this all is to use a filesystem as a primary IPC interface. Files dont necessarily mean things stored on-disk, but streams/communication-channels in an hierachical namespace. (eg. /proc or /sys). This way you have a very simple IPC mechanism using the very same semantics as filesystems do traditionally. That's just consequently using the everything's a file-metaphor. As everything's a file, all an OS or an distributed environment has to provide is dispatching filesystem operations from client to server, whereever they may actually reside. For example, you can simply mount any Plan9 device via 9P, from anywhere, as long as you get some 9P path there. (BTW: 9P doesnt have the concept of ioctl()s. If some object has more than just a single IO stream, it's modeled as an directory, eg. containing some ctl file accepting additional commands, etc). cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ cellphone: +49 174 7066481 email: i...@metux.de skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --
Re: [gentoo-user] How the HAL are you supposed to use these files?
Mike Edenfield wrote: I'm kinda stunned that your arguments against D-Bus seems to boil down to just use 9p instead No, we're talking about very different concepts. D-Bus is essentially an generic RPC mechanism (with an asychronous signalling facility). So it allows calling procedures on remote objects sending signals to listeners. IOW: fundamental concept behind GObject, QObject, etc put onto distributed level (but much simpler than CORBA, etc). On the other hand, 9P is essentially just a filesystem protocol which is very well suited for synthetic filesystems. The latter is the key point: synthetic filesystem. Instead of calling procedures, you model objects into directories and files and simply work with common filesystem operations. This is the same idea as behind procfs or sysfs, but on an distributed level. Hopefully, we agree that procfs and sysfs are a simple and easy approach for accessing many many kernel-internal data using very standard filesystem operations. Now imagine we hadn't them, but needed to use separate syscalls or netlink operations. Wouldn't it be ugly ? given that plumber is a basic element of 9p and does essentially the same job D-Bus does. No, plumber is an 9P-based service which does the message broadcasting/routing to listeners (easily programmable by an special-purpose language). Since it's based on 9P, it can be used anywhere 9P is available, fully platform independent and network agnostic. http://plan9.bell-labs.com/sys/doc/plumb.html cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ cellphone: +49 174 7066481 email: i...@metux.de skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --

Let me suggest another idea: Put a venti on the remote machine and push the tree to be backed up with vac. Never think about maintaining incremental backups anymore - just pull in the stuff, and venti will store equal data blocks only once. All you now have to do is to put the root score (printed out by vac) into some safe place. You can even directly mount the backup via vacfs :) cu -- - Enrico Weigelt== metux IT service - http://www.metux.de/ - Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ -
