bww bitwise works GmbH progress update August 2016

August 19, 2016 by silvan.scherrer@bitwiseworks.com

*bww bitwise works GmbH progress update August 19, 2016*


In the last couple of week/month we have been working on the tasks below (among a lot more).


* LIBCx
* Samba Server 3.6
* Binutils
* Coreutils
* Bison
* DASH
* GNU gettext
* HPLip
* kLIBC


*
LIBCx - kLIBC Extension Library*
The kLIBC Extension Library extends the functionality of the kLIBC library<trac.netlabs.org/libc> by adding a number of high demand features required by modern applications.


Currently, LIBCx provides the following extensions:


* Improved advisory file locking using the |fcntl()| API. The
implementation provided by kLIBC uses |DosSetFileLocks| and is
broken as it does not guarantee atomicity of lock/unlock operations
in many cases (like overlapping lock regions etc.) and does not have
deadlock detection.
* Improved positional read/write operations provided by |pread()| and
|pwrite()| APIs that guarantee atomic behavior. kLIBC emulates these
functions using a pair of |lseek| and |read()/write()| calls in
non-atomic manner which leads to data corruption when accessing the
same file from multiple threads or processes.
* Improved |select()| that now supports regular file descriptors
instead of returning EINVAL (22) on them as kLIBC does. Regular
files are always reported ready for writing/reading/exceptions (as
per POSIX requirements).
* Implementation of |poll()| using |select()|. kLIBC does not provide
the |poll()| call at all.


*
Samba Server 3.6*
**Samba is a free implementation of the CIFS/SMB protocol for Unix, which allows LAN-Server style file and printer sharing among machines running Windows, Mac OS, Unix or OS/2 and OS/2-based systems. The goal of this project is to port the Samba server and create Samba clients for OS/2 and OS/2-based systems in order to replace the functionality of the outdated IBM-LAN-Requester/Peer/Server components.


We fixed a whole lot of longstanding issues in Samba Server 3.6 like:


* Max logfile size does not work (Ticket #36)
* Adding exceptQ support (Ticket #236)
* SIGABRT on some situations (Ticket #189)
* TDBBackup does not work (Ticket #225)
* All remaining TDB Problems (Ticket #208)



*Binutils*
We updated the Binutils port to version 2.25.
Binutils is a collection of binary utilities, mostly needed to develop applications.
*


Coreutils*
We updated the Coreutils port to version 8.25.
These are the GNU core utilities. This package is the combination of the old GNU fileutils, sh-utils, and textutils packages.



*Bison
*We updated the Bison port to version 3.0.4.
Bison is a general purpose parser generator that converts a grammar description for an LALR(1) context-free grammar into a C program to parse that grammar.**Bison can be used to develop a wide range of language parsers, from ones used in simple desk calculators to complex programming languages.


*
DASH
*Because our ASH shell shows it's age we have been in the need of a more modern one. So we decided to use DASH as our new shell and ported version 0.5.9.
DASH is a POSIX-compliant implementation of /bin/sh that aims to be as small as possible. It does this without sacrificing speed where possible. In fact, it is significantly faster than bash (the GNU Bourne-Again SHell) for most tasks.


*
GNU gettext*
We updated the GNU gettext port to version 0.19.8.
The GNU gettext package provides a set of tools and documentation for producing multi-lingual messages in programs.



*HPLip
*We portet HPLip version 3.16.3
The Hewlett-Packard Linux Imaging and Printing Project provides drivers for HP printers and multi-function peripherals. It is used in our case as a addon to the CUPS printing subsystem.



*kLIBC
*We released a new version of kLIBC as RPM with an important fix. The fix prevents a possible crash when a app uses fork().
See Ticket #363 for more details. We now hope Knut will integrate this fix soon in his main branch.



*Sponsoring
*
If you want to support us or a specific project then please check out our online shop <www.bitwiseworks.com/shop>.
You are one of the people making the future possible!


*Partners*
We at bww bitwise works GmbH would like to thank our development partners, Arca Noae and Netlabs.org for their continued contribution to the OS/2 platform.
Especially without Arca Noae the Firefox port would not be possible. They help us out when we are short on sponsorship.
