About the recent USETUP improvements in the branch

[Hermès BÉLUSCA-MAÏTO]

Hi all,

 

I’m writing a short mail to explain the recent USETUP improvements I’m doing
in the
https://svn.reactos.org/svn/reactos/branches/setup_improvements/base/setup/
branch.

 

The aim is three-fold:

-          To improve multi-OSes / bootloaders detection and solve
https://jira.reactos.org/browse/CORE-4870 ,
https://jira.reactos.org/browse/CORE-12672 ,
https://jira.reactos.org/browse/CORE-13188 ,
https://jira.reactos.org/browse/CORE-13226 in a consistent & reliable way,
and possibly having a look at https://jira.reactos.org/browse/CORE-13205 and
https://jira.reactos.org/browse/CORE-10898 (low priority for me at the
moment).

-          A bit related to the previous point, have the possibility to
automatically detect existing installations of ReactOS (and of Windows) to
allow simple upgrade. For this latter part I have code that almost works: it
browses all the available partitions on all the disks, and for each,
attempts to see whether either freeldr or ntldr is installed, and if so,
open their respective configuration files, browse the latter, and from that,
deduce the candidate NT installations. On the following screenshot :
http://i.imgur.com/Nq67J1o.png , a Windows installation actually exists on
“partition(1)” but is not listed because it happens to be on an NTFS
partition. Then there is a ReactOS installation on a FAT “partition(2)”, and
finally a Windows installation on another FAT “partition(4)” (all on the
same disk). The installation detector has respectively parsed freeldr.ini,
and boot.ini, to deduce the installations, and have removed installations
having the same disk and partition numbers and SystemRoot (otherwise you
would have seen many “ReactOS (xxx)” entries).

-          To facilitate the future implementation of the 1st-stage GUI
setup by someone, all the code that can be made common between USETUP and
this future GUI setup, is placed into a library. At the time of writing,
this concerns the so-called “generic lists” functionality as well as the
partition lists & some file-system-related routines. It will certainly grow
up later.

 

Cheers,

Hermès

 

P.S.: Using a 8x8 font for the installer quickly hurts the eyes (and it has
been like that since ages). It would be great to use a more readable
resolution / font size

Hey Hermès,

Great work on the setup components! I especially like the library that
paves the way for a feature-rich graphical installer :)

Oh yes, I'm all for a good looking installer with nicely readable texts
in all languages. Which brings us to the GUI installer and to the
question what we would still need the text-mode installer for when the
GUI one is perfect?
