WIP: Fluffos 3.0 Alpha 9.0
« on: September 28, 2015, 01:15:16 PM »
Hi all,

It's been a while, and now I present fluffos 3.0-alpha-9.0 to you all.

Major changes:
1. Bundle jemalloc 4.0.3 , build process will build and link to it automatically. Jemalloc will solve memory fragmentation issue.
2. Better formatted  startup logging.
3. new RC(runtime config) system that provides a default value for every option, and output overridden ones on startup.
4. Fixed '\r' translation issue introduced since 7.4
5. Deal with CRLF in both RC configs and read_file, restore_* ,  no more translation needed.

Note:
CYGWIN build is broken for now, as jemalloc is having some trouble compiling under it.

As usual, the code is avaiable at https://github.com/fluffos/fluffos , I havn't tagged a release yet due to CYGWIN issue.

Cheers.

Great!!!
I'll test later with my mudlib.

Thank you very very much!

I was trying to test the latest alpha driver under debian against the latest fluffos release but ran into a problem when it came to understanding some of the new options in the new local options. Is there still a way to make array a reserved word since ds and nightmare libs use this keyword quite a bit.

Thanks in advance

You need to modify  https://github.com/fluffos/fluffos/blob/next-3.0/src/base/internal/options_internal.h  now to enable that.

I don't think array keyword actually give you anything, I recommend you use some global define / grep to get rid of it for the future.

Actually, array makes more sense for LPC than the old C pointer notation.

LPC doesn't allow you to (directly) use pointers as a variable type.  As such, using a cryptic pointer notation to mean an array only makes sense to people who first learned C or C++ programming.  If it weren't for trying to support legacy code, I'd actually get rid of the * notation and force the use of the array keyword as the ONLY way to declare an array.

I  guess the difficulty of removing either of them is that it now breaks compatibility with a number of existing mudlibs. Has the malloc memory allocator simplification happened? Can we still use multiple different mallocs or are we down to one?

Hello!
Since Monday, driver 9.0 is up and works ok.

In that days, only fails one time.

I could see this trace in syslog:

I understand this info is not sufficient, but i didn't see the error until ten minutes later :(

What info do yo need if that error happen again?

Except for that crash, all is ok!

Thank you very much.

You need to post whole startup-log  , and possibly put your driver binary somewhere for me to download and analyse.

For now is ok, but i'm sure that will crash again.

I'm thinking about it.

The error is in:
Code: [Select]
telnet_recv(ip->telnet, reinterpret_cast<const char *>(&buf[0]), num_bytes);

Is possible that ip->telnet was incorrect or NULL for some telnet client? (i doubt it...)

I could not reproduce the error.

I saw exactly the same crash happened on another MUD. I sent in some fixes yesterday, can you update it and see if it happens again?
