Linux debug build slave relocated
by Pierre Schweitzer 02 Nov '11

02 Nov '11

Hi, the Linux build slave will be relocated (changing data center & country) starting tomorrow. It will, obviously, be offline during the meantime. So, you will not have any Linux builds nor KVM tests. We will do our best to get it back online as soon as possible. Regards, The ReactOS Sysadmins.

Minutes from 10.27.2011
by Claudiu Mihail 30 Oct '11

30 Oct '11

Hello all, Here are the minutes from the last ReactOS meeting on the 27th of October 2011: 20:20 Aleksey Bragin called the meeting to order - Aleksey Bragin shared a video interview about ReactOS at http://alenapopova.ru/egov/react-os-kraudsorsing-pri-sozdanii-operacionnoj-… - Aleksey Bragin stated the meeting agenda as being: 1. Website revamp status 2. CMake adoption 3. Release status 1. Website Revamp ----------------- - Amine Khaldi started on the Website revamp status and stated that unfortunately nothing has progressed since the last meeting because of aross, superdog and nisky being extremely busy. - He also stated that Aleksey has yet to commit the bridges needed and that the actual milestone is the theme (ie design/layout that matches the current website), after which devs will need to investigate phpbb issue. - Aleksey Bragin added that almost the only thing left is the theme and with it progress could be made fast to the website engine and have a test run with real data. - He also stated that all details could be provided to anyone motivated enough with HTML/CSS. - Matthias Kupfer said he could support HTML/CSS around Christmas, but not earlier. - Aleksey Bragin asked Maciej Bialas if he could assist in theming. - Maciej Bialas said he could, and added that he tried to create a simple theme first resembling the current one, and that aross said he could have done better by using some Drupal modules Maciej was not aware of. - Aleksey Bragin stated that a simple theme would suffice for now and a better one can always be done later. - Ziliang Guo asked about user and forum transfer status. - Aleksey Bragin replied that the forum is phpbb and therefore easily transferable - Ziliang Guo asked about the reason for sticking with phpbb. - Amine Khaldi and Aleksey Bragin stated that it was for the sake of easier migration (ie migrate one thing at a time not everything at once) - Maciej Bialas stated that one downside to this was tedious integration with phpbb. - Aleksey Bragin pointed out that playground.reactos.org (with its intact database) will be what the new main site looks like when the switch is made. - Ziliang Guo said he can start trying to add content the coming weekend. - Amine Khaldi asked Ziliang Guo to keep everything minimalistic. - Aleksey Bragin moved the meeting on to the CMake adoption topic on the agenda. 2. CMake adoption -------------------- - Aleksey Bragin took this chance to welcome Alex Ionescu back to the ReactOS project. - Amine Khaldi stated that Alex Ionescu stumbled upon a way to separate debug info from binaries, in a pdb similar way, using objcopy. He also mentioned that Alex helped by fixing two bugs in windmc and windres. - He went on to say that Alex suggested that we go back to using dwarf-2, only this time with pdb style debug, and with an improved, out of the kernel, symbols handling. He mentioned that Thomas Faber was kind enough to sketch a batch script that takes a debug log and translates the addresses inside it. - Amine Khaldi further stated that with the script + the CMake changes to take account of windres and objcopy, we'll be able to reduce the iso size, reduce the memory footprint, reduce the disk space needed to compile, use windres alone and get rid of handling symbols in the kernel (something "no other OS does" as Alex describes it). - He then explained that, on the RosBE level, this will only require updating binutils (gcc will stay at 4.4.3) with the patched windres and windmc, and it will also require the translating script to be part of RosBE. A discussion ensued about testing the new RosBE and the following conclusions where reached: - Have a new Build Environment Release Candidate (2.0) which is an update to binutils (ld, windres, windmc, addr2line... etc) until the next meeting. - Keep the 4.4.3 version of gcc until the next meeting. - Alex Ionescu suggested having the new RosBE ready by the time of the next release. He also noted that this does not mean the new BE will be released along with the next version of ReactOS, but that it must be ready by then. - Cameron Gutman then brought up the issue of switching to gcc 4.6, but it was decided to keep gcc 4.4.3 until after the next release. - Thomas Faber then suggested an outlined step by step plan: 1) Update BE 2) Release new version of ReactOS (0.3.14) 3) Get rid of wrc 4) Get rid of rbuild 5) Switch to dwarf 6) Adopt new compiler (gcc 4.6) After some deliberating it was agreed upon that Thomas Faber's proposed course of action is the best way to go, and his proposal was accepted. - Amine Khaldi then moved the meeting to the next topic 3. Release status -------------------- - Cameron Gutman inquired about the progress on the heap regression issue. - Thomas Faber stated that although he himself hasn't made much progress because he is very busy during the week, Jerome has been tracking it down pretty well and that it is apparently caused by resource loading. - Amine Khaldi took this chance too thank everyone for the awesome bugfixing phase, and stated that a lot of bugs has been fixed and a lot of regression has been addressed. He also went on to thank testers, and outlined the importance they have, and stated that he hopes this will be the mentality of the ReactOS project team, as thanks to it ReactOS is improving a lot. - He went on to say that as far as the remaining blockers are concerned, more team work on fixing them is needed, as this has proved very effective in the past. He also added that Jim Tabor did a good one man job on the jre issue, but that the other issues could use some teaming up. - Aleksey Bragin further added to this that ReactOS is on the way to possibly one of the best releases, and that after years have passed everyone is working towards the same goal, which, he added, is fantastic. - Cameron Gutman agreed that ReactOS is indeed very stable now, especially in kernel mode. - Olaf Siejka went on to sum up that entering the release stage would require at the very least fixing mshtml bug and fixing ldr regressions. - Aleksey Bragin agreed with Olaf Siejka on that point. - Kamil Hornicek inquired about the official stance about hackfixing certain bugs. - Aleksey Bragin and Amine Khaldi both explained that while hackfixing should be avoided, there are some bugs which cannot be resolved in a timely fashion. But hackfixing these should clearly be reflected in the commit message and comments in the code. - Amine Khaldi went on to ask for a more visible teaming up, for example on IRC and through bug reports, and to also request marking bugs as assigned when devs take them. He mentioned that since the release blockers remained unassigned for a while, it was difficult at times to keep track of who is working on what. - Cameron Gutman inquired if anybody objects to modifying the default color depth from 16-bit to 32-bit. - Olaf Siejka raised some concerns about this as it will affect QEMU since it does not support 32bpp. - Cameron Cutman further inquired about the possibility of falling back more gracefully as far as color depth is concerned when a video card does not support a certain resolution (right now it falls back directly to 8bpp). He went further to ask Timo Kreuzer if this is standard windows behavior. - Timo Kreuzer said he would need to investigate this issue. - Aleksey Bragin formally ended the meeting, thanking everyone for their time and information.

Regressions / release status
by Aleksey Bragin 27 Oct '11

27 Oct '11

Hello! Time flies fast, and soon we are going to face the deadline (next status meeting) by which we decided to create a RC of the upcoming release. And, there are some problems. I will start from good stuff. Since the last meeting took place, quite a few regressions were fixed, and interesting bugs have also been closed. This is very good and I appreciate your efforts. However some problems remains, and here is where your help is urgently needed! For the current milestone (0.3.14), there are 3 blocker regressions and 2 big buckets of issues - ldr rewrite regressions and shell32 rewrite regressions. From blocker stuff, the most important is the heap-related one. Mephisto provided a good explanation here (http://www.reactos.org/bugzilla/show_bug.cgi?id=5857), and we need someone with a fresh eye to look into this problem. N.B. Please don't go into "let's fix some unrelated stuff in the heap code just to make it better". Look strictly into the specified bug and try to spot the place where the heap lists are getting corrupted. Anyone volunteers to have a look? LDR regressions: there are relatively many of them, but all are more-or-less nicely fixable because of the new, good LDR code. Alex - maybe you could please devote a bit of your time to check the code and see if that fixes some of the regressions? shell32 regressions: I already see some improvements being committed, please continue this way. We can make a good 0.3.14 release only if we act as a team now. It's not someone, it's YOUR help which matters. Testers are already doing as much as they can, retesting issues, providing newer debug logs, and other other things. Now it's time to act and fix regressions before moving further. It's just stupid to move further, if a rewrite introduces new bugs instead of fixing existing. I know how hard it is, but let's finish smaller steps and hence move forward. There is no way forward at all if old bugs are stacked and new regressions are introduced all the time. We can't bring in new good changes (wine syncs, 3rd party code syncs, arwinss, whatever else) until 0.3.14 is ready, and 0.3.14 is not ready until blocking regressions are fixed. As simple as it is. Thanks for reading and I hope you understand. With the best regards, Aleksey Bragin.

Two petitions
by caemyr＠myopera.com 23 Oct '11

23 Oct '11

Hiya Its still at least two weeks until next meeting, hence i suppose ros-dev could be used in decision making even before that. I have two things i would like to push, things that i discussed a bit with varioius team memebers on IRC and got positive feedback. I would like you guys to comment on those and if you feel that one of both of them are wrong/unnecessary/not needed, please voice it out here. If there is no opposition for them, i`ll consider those two accepted and push for them to be finialised. Here we go: 1. Adding a default theme to ReactOS. We need at least one to test Themes service in trunk ootb and avoid copying it to ros install each time, which is really important in regression testing. Also, a theme is a must for our upcoming release. Since its not a big file usually, it should be present in trunk, not only in release ISO. 2. Moving Starfield screensaver from rosapps to trunk. Rosapps, no matter how much cheered, is a wasteland, a museum, a forgotten place. It will not be even buildable when we move away from rbuild. Old and unneeded code should land there, but not a new creation Carlo has been working on. Apart from that, Starfield is using OpenGL, which is also a handy ootb test tool for 3d acceleration, also important in regression testing. If you think that two screensavers are the top amount you can accept, then lets replace one of the trunk screensavers with Starfield. -- With best regards Caemyr

Livecd video regression
by Timo Kreuzer 19 Oct '11

19 Oct '11

Hi, Since one of my recent video driver loading changes, livecd video is vga mode. The reson is: When installing bootcd, there will be only 1 video driver installed: based on 1st stage selection, either vbe or vga will be installed the other one is deactivated (start mode = manual). When installing a 3rd party driver, that one used to be installed and loaded prior to VBE and thus became Device/Video0, which win32k happily used as primary adapter. This behaviour changed with ACPI hal and VBE is loaded first, resulting is non functional VBox driver. I fixed this, by having win32k decide which driver to use, by looking if its a vga compatible driver and use that one only as fallback, if no other is present. additionally the VBE was marked as VgaCompatible. Now livecd behaves differently and simply installs both VGA and VBE. and since both are now marked as VgaCompatible, win32k doesn't know which one to use and currently uses VGA. Now how does this work in Windows? Windows has only one Adapter installed for VGA and VBE (vga.sys + vga.dll/vga256.dll/vga64k.dll/framebuf.dll) This service is always loaded and marked as "VgaCompatible". It is also used when a 3rd party driver is installed, when you switch to fullscreen console mode. This adapter is only replaced by a 3rd party adapter if that one is also vga compatible. This way its easy for win32k to decide which one to use: based on whether /BASEVIDEO is passed, either the vga compatible one or the other one can be selected. Possible solutions: 1) Add another workaround to win32k, checking if 2 VGA adapters are installed and then using the first one, instead of the second one as currently (because 1st is VGA, simply the second is used), but thats not a real solution. 2) Fix whatever is neccessary to have VBE be replaced by a 3rd party driver that is installed. (Cameron said it was related to VBE not being PNP ready.) This way we can stop marking it as VgaCompatible. 3) Combine VGA and VBE miniport into one vga compatible driver, like it's in windows. Alex mentioned that eVb has more or less finished that. Question is: whats missing to have the code comitted? Comments and feedback appreciated, Timo

Re: [ros-dev] [ros-diffs] [jgardou] 54179: [WinMM] - avoid buffer overrun. - do not try to unload uninitialized driver. See issue #6343 for more details.
by Timo Kreuzer 17 Oct '11

17 Oct '11

I think that will not unload the last driver. Looking at MMDRV_Install, MMDrvsHi is the index of the first free array field and its incremented each time MMDRV_Install is called. The assert in line 465 is wrong. It should be "<". The for () loop in line 432 is also wrong Your change starts with MMDrvsHi - 1, the last used index, then decrements i by one before doing anything else.

CMake migration of Trunk_x86_GCCLin Debug Buildslave
by Colin Finck 16 Oct '11

16 Oct '11

Hello all, The "Trunk_x86_GCCLin Debug" Buildslave has been migrated to RosBE-Unix 2.0-RC1. All builds starting with r53983 are now created using a CMake environment. Unfortunately, the CMake builds don't boot under KVM on the same machine, but apparently for everybody else. To give you an idea what I mean by "don't boot": http://img830.imageshack.us/img830/5145/image1iz.png If nobody has an idea how to debug or fix this, I'm afraid I have to revert everything back to the rbuild scripts until a proper solution is found. - Colin
