Hi,

Well, I'm currently testing last version of reiser4 and it seems to be fast
and reliable.

namesys website seems to be off now ... I wondering where this fs will  go
now ?

It's in curse of import in kernel or totally abandonned ?

Any idea ?

Thanks

That's no wonder, Namesys is currently out of business due to Mr. Reiser's 
ongoing court trial.

 ... I wondering where this fs will  
 go now ?

It's in the -mm tree since a long time now and AFAIK one or two former 
namesys employees are still working on it.

 It's in curse of import in kernel or totally abandonned ?

Don't know.

Reiser4 will probably die a quiet death now. Without Hans' vision 
driving it, it will probably do what it's been doing for 18 months - 
going nowhere.

And it's highly unlikely that Linus will ever pull it into mainline. The 
reiser coding style is somewhat ... problematic for kernel devs

Hans is accused of murdering his Russian bride and is on trial right

Legal attack on Hans Reiser? Oh, you don't know the story?

Okay, short version: Hans is a weird person. And now, his wife
disappeared and the police found indications (alot) that he murdered
her. And now all of Namesys' money is spend on defending him.

What do you mean by Hans is a weird person.? Do you know him

lecture with him talking about namespaces and filesystems (he seemed
perfectly normal there at least). And I use his filesystem (reiser3.6),
which has worked perfectly for over 3 years on my laptop. How likely is
it that he would have committed such a crime? What motive would he have?

That sounds like the perfect way to harm the free software community.

With all due respect to Hans Reiser, and I use his filesystem myself, I
don't think his incarceration would significantly harm the OSS community.
It's a filesystem, there are plenty of others of comparable quality.

Nor does it have anything to do with the Russian legal system, as
everything is taking place in the US, where everybody gets as much
justice as they can afford.

read the lkml archives. read the current blogs about how Hans is 
conducting himself in a court of law. Read his statements to the police 
when questioned about his wife's disappearance. Read his defense. Read 
his website.

What comes out of that? Hans Reiser is a typical geek who has a problem 
seeing the same reality as the rest of the world. It's very common 
amongst geeks, and we can mostly spot it a mile off. It's not rocket 
science.

I also use ReiserFS-3.6 and it is a very good filesystem. That is one 
thing. There is this other thing, which is the ability to musrder 
someone, and that is totally unrelated to the ability to write 
self-balancing filesystem metadata trees.

Any associated opinion between his skill as a coder and the likelyhood 
of his having murdered or not murdered his wife is an illogical opinion

You must be new here.

Hans Reiser? Important? I don't think so. In the general scheme of 
things he's about as important as ESR.

If you wanted to bring free software into disrepute there are many much 
more likely targets:

Linus, Alan Cox, Ingo, RMS, drobbins, Theo, Andrew M, Patrick V, Miguel, 
David R.

 Is there any

Look at the case itself.

Hans has a distorted view of reality as seen by the rest of the world. 
His wife is apparently a bitch of note. That's motive #1.

You want a likely suspect for who could have framed him? Try the 
disappeared wife's current boyfriend. Tons of suspicious actions 
there - read the court records, it's all in there.

This whole court case is entirely explained by human greed and emotion 
in marital affairs. It is not necessary to involve free software to 
come to an entirely reasonable explanation, in much the same way that 
the Enron CEO's hobbies do not feature in the explanation of the

Patches are more difficult to find but not that much.

It's been languishing in -mm for ages, never mind any progress that 
namesys itself might make with their own code.

In a nutshell, Hans tries to swim upstream with the linux kernel devs. 
That doesn't work in life, it doesn't work with one's spuse and it 
won;t work with Linus and the other devs. Just because code is involved 
doesn't mean that normal human interaction doesn't apply

  And it's highly unlikely that Linus will ever pull it into
  mainline. The reiser coding style is somewhat ... problematic for
  kernel devs

 the problematic coding style was not a problem for XFS. But hey, one
 of the biggest reiser4 critics is also XFS dev 

Reiserfs is designed to fit into the linux kernel, it's the whole total 
reason for it's existence.

XFS on the other hand, was a pre-existing body of code written by SGI 
for Irix. SGI essentially said to lkml Look, here's this stuff that 
works on Irix. We think it's cool and we're willing to let you have it. 
Want it? The kernel devs accepted it knowing full well that the 
circumstances were entirely different from say ext2/3 and it had to be 
accepted and used under fundamentally different viewpoints from most of 
the other stuff in the kernel. Linus was especially sane on this point 
and refused to be a pedantic git when he said Under no theory of 
copyright can this ever possibly be considered a derivative work of 
Linux.

It's a classic example of the point where geeks need to realize that 
humans get involved with stuff like this, and human needs, wants, 
desires and feelings will always override strict pedantic rules more 
suitable to cpu code execution.

We geeks are very fond of saying that we will accept kernel code based 
purely on it's merits as code. That frankly, is bullshit. We are LESS 
susceptible to this than most other occupations but the human element 
is always present and still has to be accounted for and confronted.

Want another example? Jeorg Schilling. The man writes excellent code, 
but he's an infuriating git that no-one can work with. The hassle of 
putting up with him is less than the hassle of simply forking his last 
code where the license is uncontested. Guess which happened.

  Current status of Reiser4 (Jan 31, 2008).


  I. Todo for inclusion:


This is an update of the following version:
http://209.85.129.104/search?q=cache:tzvFNZjSsNYJ:pub.namesys.com/Reiser4/ToDo

#10,11: Cleanups. There are 74 pending patches prepared by Dushan:
http://marc.info/?l=reiserfs-develr=1b=200710w=2
which are supposed to be reviewed by another person and pushed to
the current -mm as a big single patch _before_ the next portion of
cleanups.

#3 There is a pending patch to review/merge:
http://marc.info/?l=reiserfs-develm=119316601418489w=2

#9: I don't see any leaked jref there. Perhaps we need to rewrite this
portion of code to make it more clear.

#1,2,4: Here we need to explain why the pair igrab/iput (igrab in
reiser4_writepage, iput in entd()) won't hummer inode_lock. Actually
we need to pin inode for entd, as inode can be reused, or evicted from
memory at the moment when entd starts to process the request. Entd is
a kernel thread, which performs an active response to every memory
pressure notification (writepage). IMHO this is not a good design.
Getting rid of entd would address #1,2,4 automatically (currently I am
working on this).

#5: Here should go detailed comments how do reiser4 respond to memory
pressure notification (writepage, see above). If mainline vm experts
will be unhappy with this, then, I guess, we'll need eflush back, plus
a eflush port for cryptcompress file plugin. Eflush (emergency flush)
is a passive response to writepage(), which pushes dirty pages to
temporary location on disk. Eflush code for default (unix-file) plugin
has been dropped ~1.5 years ago in accordance with Hans' direction in
order to stimulate better solutions.

#14 Should be marked as not done and needs to be addressed.


II. Longterm todo


Here are some technical details for the items listed in this document:
http://lwn.net/Articles/226251  (see Appendix D, 11.2-11.4).

Xattrs support (listed as #12 in the previous todo, but not necessary
for inclusion) would be a serious project which requires only
knowledges of VFS/Reiser4/Reiser4progs internals. I think that xattrs
should be implemented via special reiser4 stat-data extensions.
However, currently reiser4 supports only solid stat-data items (an
item is solid, if it consists of exactly one unit, i.e. can not be
split into two or more mergeable items). It means that amount of
information contained in file's xattrs will be restricted by ~4000
bytes (blocksize - size-of-node-header - size-of-item-header -
size-of-standard-stat-data-extensions (for i_size, i_mtime, i_ctime,
i_mode, etc..)). I don't know if it is enough to integrate reiser4
with Selinux. If not, then we'll need one more stat-data item plugin
to support not solid stat-data items.

As per encryption support: current reiser4 kernel module and
reiser4progs are pretty aware about this, so IMHO we just need an
integration with some existing key manager (I would take a look how
things are going in eCryptFS). Also we need a fast IV generator for
chaining cipher modes. I have proposed a simple one based on iv-seed,
which is calculated as object's id (i_ino), but not sure if it is
stable against watermark attack.

ECC-signatures support should be implemented via a new node41 plugin
(i.e. we need to define proper node format and plugin methods that
take into account space for per-node signature storage (for example,
if we use an adler32 checksum as ECC-signature, then we need 4 bytes
per node). Supporting such signatures allows to increase robustness.
Currently reiser4 performs data (not metadata) checksumming for files
managed by cryptcompress file plugin. However, metadata protection is
not a less important feature. I think, that we need something like
Reed-Solomon signatures rather then checksums, because all modern hard
drives already perform checksumming. I believe there are reasonable
GPL's libraries that implement RS-arithmetic which can be interesting
for us.

All reiser4 documentation has been performed as comments in the source
code. Also there are links to some useful stuff:

Hans was never one of the programmers. He had the vision and paid them.

The vision is not needed anymore and at least two of them still continue 
improving it.


  


I would assume tho that the people programming have lost their funds and 
has slowed down their writing.  After all, we all have bills to pay.
