Programming / Re: A little help with OS/2 Warp Architecture Components
« on: March 06, 2013, 11:32:23 pm »
I don't think anything uses ring 2 in any OS. OS/2 is unique in using ring 1, namely for DOS device drivers, and even the OS/2 device drivers don't all run completely in ring 0 IIRC.  Used to have an ATI video driver which during boot advertised that it had a ring 0 component and IIRC IBM and MS had a falling out over whether the video system should be in ring 0 or not with MS pushing for ring 0 for speed and IBM more interested in stability back in the OS/2 1.x days.
Perhaps someone more knowledgeable can verify my memory.

and start to use the same font support that the Mozilla derivatives are using. At least the source is available, so problems should be fixable (I don't know if that would actually work either).

Easier said then done as it would probably take a lot of rewriting. Mozilla uses Cairo http://cairographics.org. Actually following the examples link does show that work has been done on adding Cairo to OO. Nothing recent though, see https://www.google.com/search?domains=www.openoffice.org&sitesearch=www.openoffice.org&resultsPerPage=40&q=cairo&Button=search.

Doodles Screen Saver has some Cairo based modules and WPS-Wizard ftp://ftp.netlabs.org/pub/wps-wizard/ adds some classes to the WPS that adds Cairo support. Unluckily it is not the most stable and source is unavailable. Screen shots at http://svn.netlabs.org/wps-wizard

I use a RAMFS volume with 1 GB, seems to work fine. Also with 1 GB, my swap hardly ever grows to over 300 MB so 1.5 GB should be ideal. I did have Thunderbird run away one day and the system crashed with a swapfile full error. Seems that it was actually a 2 GB limit on the swapfile.

What impressed me about installing Warp V3 was after the first 5 floppies IIRC, the system rebooted to the desktop and it was functional enough to start reading the documentation while loading the other 8 or so floppies.

Applications / Re: Qpdf
« on: February 06, 2013, 10:08:12 pm »

In order to try and see what the problem is I attempted to start my browser. No go, Seamonkey will not start with any established Profiles or with the Profile Manager.

I closed qpdf and retried Seamonkey - which started without problems.

So, qpdf can print once and does not allow Seamonkey to start while qpdf is running. No problem starting qpdf with Seamonkey already running though.


The problem is that the fntcfg2.dll shipped with qpdf is incompatible with SeaMonkey and probably Firefox and Thunderbird 10.12. Fix is to replace it with the one meant for Mozilla,
or remove it and have the Mozilla versions in your libpath.
The freetyp2.dll for Mozilla is probably newer as well.

There's still activity on usenet.

Setup & Installation / Re: eCS 2.2 YUM/RPM question
« on: February 01, 2013, 05:28:02 am »

At the moment, I do not have a second boot system on that machine, so I cannot comment on what will happen if I try to share the RPM/YUM installation between two boot systems.


I'm sharing a RPM/YUM install between 2 boot partitions, works fine. In my case I never did let it write to config.sys due to conflicts with my existing %UNIXROOT% volume which has EMX stuff on it. Just use a script to enable it.
All the RPM/YUM stuff is self-contained on the volume that %UNIXROOT% points to except what usually goes in config.sys, PATH, LIBPATH, various Python and probably Perl settings so they can find themselves etc.
I can't imagine the installer insisting on using the boot volume for RPM/YUM and really it needs to be installed to the root of whatever volume it is installed to. Ideally %HOME% should probably be on the same volume as some programs are likely to not understand drive letters.

Setup & Installation / Re: Can't use Facebook and Twitter in Firefox
« on: January 29, 2013, 07:10:28 am »
Make sure you have set
Quote
gfx.downloadable_fonts.enabled=false
You may set that by using about:config

This definitely fixes non-flash related Facebook crashes. The same applies for several other sites - don't know for Twitter at the moment.

That should be set automatically now, especially on the latest ESR releases though doesn't hurt to double check.
Einar needs to do a couple of tests. Start Firefox in safe-mode, easiest by going to help --> restart with addons disabled. And try a new profile by starting firefox -profilemanager and creating a new profile.
From the sounds of it he has separate profiles on 2.0 and 2.1 with the 2.1 one broken but until he returns and tests more...

I had assumed it was because our versions are following the commercial ESR line which makes it up to date.

That was as much luck as anything though I did have the goal of getting 10 out for the reason that it would be supported for over a year.
The rapid release cycle made it very hard for a couple of people to keep up. Perhaps one person working on it full time would have but after Peter moved on and Mozilla switched to the release every 6 week schedule...
Mozilla has a lot of people employed developing Firefox and we've never had more then 3 or 4 since IBM moved on. And it can be tedious.

What was the technical limitation because the Firefox ports didn't went from version 10 to 11 and follow on?


Short story, by FF10 I was the only one left building and halfway through 11 it broke and I didn't have the skills to fix it.
Long story, after FF4 they dropped support for non-ipc (interprocess-communication allowing tabs to run in their own process so when Flash crashes it would only take out the tab it was running in, Flash crashing is a problem on all platforms) and mostly Walter kept the ipc patch alive. This was a very tedious process as the patch grew to 280KBs (980+ lines) + supporting patches of about 75kb which had large amounts that needed to be applied by hand. Walter did an excellent job of keeping the patches up to date but had personal problems and got tired of rebasing the patches and moved on.
The other problem was development moved on under the assumption of IPC existing so more things didn't work. I had to remove various things like battery status that were aimed at mobile devices anyways. Eventually most of the HTTP code was rewritten in such a way that I didn't have the skills to fix it.
Also I go through phases of working on it, then getting sick of hours of typing #ifdef MOZ_IPC #endif, then trying to figure out the remaining unresolved symbols.
At this point I feel that without IPC support which Rich estimated at a man-month of work for a skilled developer we won't go on. It is being worked on though not by me.

Try going to C:\home\default\mozilla and search for and rename all copies of pluginreg.dat with the browser closed then restart the browser.

Hi Paul, what is your recipe for compiling odinized cairo? Which freetype, fontconfig etc are you using and how do you run configure?

Get the feeling this is for uniaud and I don't use that.

Not just for uniaud - libkai is used by mplayer too for all cards afaik
There is only a uniaud.dll, the rest of the files are for compiling. Download everything and compile (trying  :o) myself, but then?

It falls back on DART if uniaud isn't available. See kai_dart.c and kai_dart.h. DART is part of MMOS2 so there won't be any DLLs

Recent wget doesn't build cleanly. Might I suggest xz as a starting point. Seems to be very portable, is being used quite a bit, often with tar giving tar.xz archives and at least here DLLs also built fine.
