Why is Boost being downgraded from Version 1.42 to the older 1.41?

ejmarkow · 2010-03-19 13:14:25

Just ran pacman -Syu and noticed the package Boost Version 1.41 is going to replace the newer Boost 1.42. Why the downgrade, does anyone know what happened? I personally didn't have any conflicting issues with Boost 1.42, perhaps others have? By downgrading versions, many new features such as library improvements in Asio, Circular Buffer, Fusion, Graph, Integer, Iostreams, Program Options, Property Map, Regex, Spirit, Unordered, and Xpressive are being lost.

It's not an answer, but I see the older version is in Testing:

[stijn@hermes ~]$ pacman -Ss boost
testing/boost 1.41.0-1
    Free peer-reviewed portable C++ source libraries
extra/boost 1.42.0-1
    Free peer-reviewed portable C++ source libraries

A bit bizarre...

I guess because of this:

Hi,
http://bugs.archlinux.org/task/18470#comment59302
there is a serious issue with boost 1.42 and upstream doesn't have a fix yet. An user suggested that is better to downgrade boost to 1.41.
What do you think about this? Wait upstream to fix this and backport it or downgrade? If downgrade, who want to help on rebuilding?

I am against the downgrade of boost.
We have to find a solution for encfs, and we cannot downgrade and rebuild all of the packages just for encfs.

maybe i wasn't clear. encfs is a special case and is broken because of a bug in boost. pasting the comment here:
> What distribution are you using? A ticket needs to be filed with that > distribution that they should *not* upgrade to boost-1.42, as it can > cause silent data lose for programs using boost serialization.

so what i'm understanding from here is that upstream doesn't want us to ship boost 1.42

This is not "just for encfs", but for serious datacorruption. Encfs is
an example of something that breaks, but if serialization and
deserialization doesn't return the same data as the input data, then
things can go seriously wrong.

Damn...we must proceed with the downgrade.
I can rebuild mine and some others packages tomorrow.

Go for it. It is a small rebuild list and can be moved from [testing] as soon as the build is finished (we know 1.41 works...).
I'd appreciate if this was done quickly. I have a toolchain update and the start of the gmp rebuild sitting on my here waiting to upload.

Hi,

I'm just rebuilding mkvtoolnix and source-highlight against testing/boost.
