[Corelinux-develop] Hello All

[Dale H. <da...@sb...>]

Hi all,

My name is Dale Hirt, and I have just become the newest member of CoreLinux.
I came across this library last week, and I'm looking forward to making some
good contributions.  

I am a systems admin in Washington state, with a bit of free time on my
hands.  I have mostly been hanging around the edges of Sourceforge for the
past 6 months, so I'm glad that I have a chance to do some actual coding.
I've already done a little bit, and am planning a bit more.  I was just
wondering what I can do to help get a next release out the door, and also
whatever cleanup needs doing.

Looking forward to working with you all.

[Corelinux-develop] Signing Off

[Hans D. <dul...@cs...>]

Frank and Christophe,
    Due to my current responsibilities and activities, I do not have
enough spare energy to contribute to the CoreLinux++ project anymore.
I'd like to sign off from this nice team, unfortunately with some
pending tasks assigned to me.

It has been a nice experience working together in this team with you
guys, I also learned a lot from this project.

Au revoir. I'm sure we will see each other again, perhaps at a
different  cyberplace.

I noticed this summer! For the first time in about 4 years I actually didnt 
do either work nor school in the whole of August!

ps. I did some work on the docs in september, but nothing worthy of 
submitting. Im off to go finish some math proofs at school... :)

Corelinux is in incoming for Debian
it is lintian error and almost warning free

I'll try to do the changes in one shot, 
actually I did them for 0.4.32 debian release 
and it is just updating some scripts: ltmain.sh config.*

Once Corelinux (libcorelinux) is fully in Debian, I'll work on 
libclfw and libclfll.

As you can see, I am truly engaged in maintaining corelinux in Debian :)
The good thing is that corelinux will receive,I hope,  more input.

[Corelinux-develop] some issues

[Christophe Prud'h. <pru...@MI...>]

Hi all,

I am, finally, putting corelinux into debian !
two days ago I uploaded my first one successfully (not rejected :) )
now it is time for corelinux and I am in trouble ;)

In Debian unstable, the last version of the autotools are used
automake, libtool and autoconf.
I am packaging 0.4.32 and I am in trouble with ltmain.sh
for libtool.


So I change this file in 0.4.32 but may be we should try to port
0.4.33 to the latest versions.

It seems that we have have trouble like other big projects.

comments?

Alright.  To make sure we're on the same page: I presume you mean that all
R/O operations involving the underlying pointer be re-entrant.  And the
write operations must be guarded.  Yes?

It is overkill, but I believe you get the idea of the semaphore (mutex)

Um... I don't follow.  I'm sure it's just my inexperience shining
through.

Each SP obviously needs a (dumb) pointer and a reference count.
Modifications to these need to be thread safe, right?  Now... it would be
pure evil to give each SP type a static locking mechanism.  I've done it
by giving each SP instance a mutex, but is this overkill?

You mention semaphores... are you talking about implementing
mutexes/critical sections (for pointer/ref. count mods) with semaphores?
If not, I'm lost.

As for semaphore pools... are you talking about something clever to avoid
my (wasteful?) "mutex for each instance" scheme?  Like I said, I don't
follow.  :(

Does this replace #7 or is it over and above it?  If the latter, then what
does #7 really mean?

Re: [Corelinux-develop] Smart Pointers

[Frank V. C. <fr...@co...>]

To answer your first question:

It is all to often we see the myopic view of the world where context 
often become part of a static type. For example, rather than take the 
time to create things like semaphore pools, a developer unilateraly 
decided that each SP type (A, B, Foo, etc.) has a single semaphore in a 
static variable. ugh.

And now that you brought it up (if you knew it or not with reference count):

8. Reference counts must be guarded
9. Object state must be guarded

Thoughts?

Just to clear up some terminology, when I think "re-entrent", I envision a
function that, using a context pointer or some other device, can be called
by more than one thread simultaneously with out further use of
synchronization objects like mutexes.  Something that requires extra
synchronization logic I just think of as being "thread-safe".  Is there
really a difference, or is it just me?

Anyway, I wouldn't ask if I wasn't curious how you planned to make things
like reference counting re-entrent.  Maybe it's just my definitions that
are screwy, or maybe you have some truly magical ideas. Or both! :)

[Corelinux-develop] Smart Pointers

[Frank V. C. <fr...@co...>]

Smart Pointers (in no order):

1. Should be able to be garbage collected
2. Should be able to release the object that it points to when asked
3. If needed (dirty object), the object being released should be 
persisted (paged out)
4. If requested again, with the object paged out, it should be paged in
5. Must have a reference counter, not just a single "in use" notion
6. Must be created and destroyed by a factory (this make caches and 
memory management much easier)
7. Must be re-entrent

For each one of these there is a lengthy discussion and I've yet to 
discuss the implications to the FrameworkEntity types.

Lets talk this one out as it is near and dear to my heart :). I have a 
tremendous experience with SP in large complex application work, and I 
don't want to take this lightly.

Yep.  The only thing it doesn't lend itself to is collections.  Without a
common base class, it's difficult (inconvenient, at least) to have a
collection of Smart Pointers whose policies aren't identical.  Obviously
no problem when the policies are the same, but...

Unless there's something I'm missing?

It is sophisticated from the Design point of view, but not so from the us=
age point of view
since you have the default behaviour already plugged in!
If you need something slightly different, just implement the policy chang=
e you need and=20
that's it! It is Reaaallly neat and lots of fun too.

Unfortunately no.
I  come from a background where it is heavily used(scientific/intensive c=
omputing)
In corelinux it is more "conventional". Templates are just showing there=20
full power. It started ~4 years ago with meta-computing, expression templ=
ate
and other new programming techniques using templates; and now design usin=
g C++ has a new face
which is very appealing!  I'll try, with Frank approval, to incorporate s=
ome of these
new design ideas in corelinux.

Some Design Patterns in CoreLinux could benefit from these new ideas: for=
 example the Factory
Pattern.

Ooo... I like that! :)  Much more sophisticated than I need, but very
nice.

Is the Policy pattern widely used in CoreLinux++?
