Status Meeting (April 2018)

by Colin Finck

Hi all! Let me invite you to the April 2018 meeting, taking place this Thursday, April 26, 2018 at 19:00 UTC. There have been no requests for additional agenda points yet and I'm not aware of any developments of the outstanding points of last meeting, so right now the agenda only includes the Status Updates. If there is something you want discussed this month, please reply to this mail. As waiting for every developer's Status Report still wastes too much time each month, I'm asking everyone to prepare a short text in advance. Unlike previous meetings, let's all try to post our status updates simultaneously this time and let the IRC server handle the congestion. This may make some reports harder to read, but we should be able to move on much quicker. Best regards, Colin

It seems to only be used at low IRQLs, so it seems logical. However I see it allocated nonpaged everywhere else and can't seem to find definitive documentation on the subject. (And yes, most filesystem drivers use a static structure, but those drivers don't use MmPageEntireDriver) Thanks, Thomas

Re: [ros-dev] [ros-diffs] 01/01: [WINLOGON] Clean up part 2 - Replace the UNICODE_STRING usMessage by a PWSTR pszMessage. - Use the "%02d:%02d:%02d" time format and get rid of the safe string printf because the string will NEVER be longer than 8 characters. - Rename the timer id constant because it is NOT a resource id. - Rename variables according to the coding style.

Hey Eric, On 2018-04-02 12:58, Eric Kohl wrote: > - RtlStringCbPrintfW(strbuf, sizeof(strbuf), L"%d:%d:%d", hours, minutes, seconds); > + swprintf(szBuffer, L"%02d:%02d:%02d", iHours, iMinutes, iSeconds); Unfortunately I must disagree with this change. Buffer overflows are a big enough threat that code review and static analysis are not generally considered sufficient to protect against them. So it's best practice for new code to always verify sizes at run-time, and never to use s(w)print. Best regards, Thomas PS: from what I see, iHours can be as large as 1193046, which won't fit in 2 digits

Re: [ros-dev] [ros-diffs] 02/08: [NTOSKRNL] Forbid processes without the Tcb prvilege to perform a user-mode hard-error BSOD.

by Alex Ionescu

So to be clear, while the kernel still has tons of incompatible code and issues to barely run as a Win2003-compatible kernel, whenever there's an NT design decision you disagree with, you're going to be rewriting the little bit of code that _does work well_ to work contrary to how NT works? Did I get that right? Good luck.

If I remember correctly you can make shutdowns delayed of many days on Windows (using the InitiateSystemShutdown(Ex) function), in which case the 2-digit hour won't work at all.

d2d1 in ReactOS

by Giovanni Mascellani

Dear ReactOS developers, I am nosing inside Wine and ReactOS code to understand something of their inner workings. I wanted to compare the code of d2d1.dll, but apparently ReactOS does not have it. Is this intentional, is it just still to be implemented, or is there any other explanation? Thanks and all the best, Giovanni. -- Giovanni Mascellani <g.mascellani(a)gmail.com> Postdoc researcher - Université Libre de Bruxelles

GSoC 2018

by Abhishek Singh Bisht

Hi there, I am interested in a couple of projects under System enhancement, that I found on your projects list: 1) NT6 Recycle Bin Project 2) Search Shell extension 3) WebKit based MSHTML implementation Kindly help me choose one, if I could get some more information regarding the projects, it would be really helpful and I can go ahead with the proposal. Also, I have performed a complete build of ReactOS Live CD, and Boot CD and gave it a test run. I found it lacking a decent browser, tried to run iexplore.exe but it still couldn’t load any web pages. I might be able to create something to help improve on this. Looking forward to contribute to this reactOS. Thanks, Abhishek

Yet another GSoC proposal

by Victor Perevertkin

Hi all! I am a student and I want to try to participate in gsoc this year. I follow ReactOS news for 4 years, I think (and even reported a few bugs). I am a web developer but some time ago I started to study ASM and C (but no C++ yet) in my university and found it very interesting for me. I want to learn more about OSDev and maybe join your team finally :) There are some thoughts about what I want to do for ROS during this summer. 1. Make ReactOS boot from btrfs. As far as I understand, freeldr does not support btrfs and this code must be written. And boot sector ofc I prefer this task the most (as for now). But maybe you will dispel my dreams by saying that it requires too much effort for summer internship :) 2. I've already talked with Thomas Faber on IRC and he said that there are some drivers that are in need of being (re)written. NICs and bluetooth drivers may be interesting to me but I'm not sure if I can get through it. So I'm asking your advice. Are this things doable for a student? Maybe there are some other interesting low-level things for a GSoC'er? Do you have mentors for them? Basically, I want something low-level which doesn't require deep knowledge of NT internals. Thanks! Victor Perevertkin

Re: [ros-dev] [ros-diffs] 01/01: [NTOS:KE] Replace "Fatal System Error" with "BugCheck"

Re: [ros-dev] Chemnitz Linux Tage, who will come by and support the booth?

by Daniel Reimer

Hello once more. Thanks for the single answer I got asking to take part. But I need one more booth supporter, preferred are team members. You have time till today evening to answer, otherwise I am not sure if I should blindly reply with the yes aka we will take part in CLT the team behind it is waiting for. In the end I reply and no one shows up. It is up to you. I got my holidays accepted last year already for being able to take part. What about the rest of the team who did not reply with a good reason not to take part already?

RFC: Change Rapps 'Size' field

by Mark Jansen

Hello, I'd like to propose a change for the 'Size' field: Currently this is a localized, pre-formatted field. By changing this to the actual size in bytes: - We can use StrFormatByteSizeW to format it locale dependent (without the need to manually translate it) - We can use this value to display the progress bar, in case the download itself does not provide this value (for example, web.archive does not provide this). For backwards compatibility we should probably add this as another field, so that the 'old' rapps can still read the 'Size' field. Regards, Mark

Dynamic libxml2/zlib

by Thomas Faber

Hey Amine, seeing https://jira.reactos.org/browse/CORE-14288 just prompted me to look into static vs dynamic 3rd party libraries, zlib and libxml2 in particular. We use zlib in a bunch of modules these days, and libxml2 is large and used in two, so I'm thinking we should make them dynamic. I just did the experiment for libxml2 and it resulted in at least 0.5MB binary size reduction and 2MB build folder size reduction, so clearly seems worth it.[1] I'll do the test for zlib as well to make sure that's also an improvement. However I was thinking there might be a reason why we build those statically right now. Do you (or anyone else) recall anything that makes switching to dynamic a bad idea? Thanks! -Thomas [1] Raw results: Static libxml2 (MSVC debug with RTC): msxml3.dll - 1887 KB libxslt.dll - 1142 KB libxml2.lib - 4953 KB (build dir only) Dynamic libxml2 (MSVC debug with RTC): msxml3.dll - 799 KB libxslt.dll - 259 KB libxml2.dll - 1592 KB libxml2.lib - 371 KB (build dir only) Static libxml2 (GCC debug with -O1): msxml3.dll - 3856 KB libxslt.dll - 2776 KB liblibxml2.a - 48 KB (build dir only) Dynamic libxml2 (GCC debug with -O1): msxml3.dll - 1505 KB libxslt.dll - 429 KB libxml2.dll - 2553 KB

Making bluescreens more useful

by Thomas Faber

We often get bug reports with just a screenshot of a bluescreen; we then go ahead and tell people that bluescreens are basically useless, they should get a debug log and a backtrace, and also remember to tell us what version they're using. Since there's actually no reason why bluescreens need to be useless, I thought I'd try to change that. I've attached an example. The source for this quick PoC can be found at https://github.com/ThFabba/reactos/commit/6a9f172b76bd11f763598c16e5d47299e… Thoughts?

First NT6+ application support in ReactOS

by Colin Finck

Hi all! Starting with build 0.4.8-dev-655-g63a3a2c, ReactOS has first support for NT6+ applications (aka programs written for Windows Vista, Windows 7, etc.). Please retest such applications under ReactOS! As newer Windows APIs are still missing in ReactOS, I would be surprised if a high number of NT6+ applications suddenly works. However, many applications may just be compiled by a new Visual Studio without using any modern APIs. They could work now. My "Hello World" compiled by VS 2017 v141 toolchain printed many messages about missing apiset DLLs in the debug log, but otherwise works well. So the next step should obviously be finishing and integrating Mark's work on the apiset DLLs in https://github.com/learn-more/reactos/commits/apisets But interestingly, the build produced by the v141_xp toolchain also looks for these apiset DLLs. Therefore, it would be possible that an application expects a full NT6 system when finding them. Consequently, application compatibility could be compromised if we just dump all apiset DLLs into ReactOS, applications now expect NT6, but the OS continues to behave like NT5 by default. This is why I suggest detecting an NT6+ application in ntdll to have it auto-apply a shim that lets ReactOS behave like an NT6 OS. The apiset DLLs should only be available in this mode, but not for the NT5 personality of ReactOS. Let's not import the apisets before the ntdll shim work is done in order to preserve our existing application compatibility. Cheers, Colin

Someone's suggestion on IRC about adapting the PS4 linux loading to boot ReactOS

by David Quintana (gigaherz)

Quoting directly from IRC: [18:22] (Figarocool): hi! [18:23] (Figarocool): is someone online? [18:23] (@gigaherz): yes [18:23] (Figarocool): you a developer? [18:24] (Figarocool): a loader was developed for a few days to load linux on ps4 [18:24] (Figarocool): https://github.com/fail0verflow/ps4-linux [18:25] (Figarocool): would it be possible to port this to start rectos? it would be something of great visibility for the reactos project [18:25] (Figarocool): loader [18:25] (Figarocool): https://github.com/valentinbreiz/PS4-Linux-Loader [18:25] (Figarocool): on firmware 4.05 [18:25] (Figarocool): ps4 runs on x86 [18:26] (Figarocool): would it be complicated to do this for you? [18:26] (@gigaherz): I don't own a ps4 and I'm not an expert in the reactos booting process, so I'm not the right person to ask [18:27] (Figarocool): could you open a discussion about this? [18:28] (@gigaherz): well this is IRC, just talking about it is already a discussion [18:28] (@gigaherz): but if you want something more "official" [18:28] (@gigaherz): you can post this information on an email to the ros-dev mailing list [18:28] (@gigaherz): (subscribe to the mailing list if you want to see the replies) [18:29] (Thedarkb1): You probably could. [18:33] (CatButts): hmmm [18:33] (CatButts): unlike PC, PS4 is single hardware configuration [18:33] (CatButts): getting ReactOS on a PS4? hmmm, that wouldn't hurt [18:34] (CatButts): [19:25] <Figarocool> it would be something of great visibility for the reactos project [18:34] (Figarocool): check: https://github.com/valentinbreiz/PS4-Linux-Loader [18:34] (Figarocool): loader to load linux (x86) and driver [18:35] (Figarocool): however, since reactos and open would be a great novelty for the knowledge of the os [18:35] (Figarocool): so it could give a lot of novelties in the media aspect [18:35] (Figarocool): you could think about it [18:36] (@gigaherz): the loading process of NT is very different from linux [18:36] (@gigaherz): but as I said, because I'm not the right person to ask [18:36] (@gigaherz): it would be best if you put the information on the mailing list [18:36] (@gigaherz): for all the people interested to read [18:36] (Figarocool): could you open the discussion on the mail? [18:37] (@gigaherz): I think it would be best if someone who is actually interested in it would do so [18:38] (Figarocool): I also say this because of the media aspect [18:39] (Figarocool): since they are now installing linux to use the console as a PC [18:39] (Figarocool): this would be great using reactos [18:39] (Figarocool): being x86 all windows games and more would be compatible

Project-tools repository converted to Git - Welcome our 18 new repos!

by Colin Finck

Hi all, I just finished converting our "project-tools" SVN repo to Git and splitting it up into individual repositories in the process. These repos have already been uploaded to GitHub (https://github.com/reactos), so you can have a look and comment easily. Welcome these 18 new repositories: * ahk_tests * buildbot_config * git-tools * irc * Message_Translator * monitoring * packmgr (Archived) * project-tools-archive (Archived) * Qemu_GUI * reactosdbg * Release_Engineering * RosBE * rosev_ircsystem * rosev_jameicaplugin * RosTE * sysreg2 * sysreg3 (Archived) * vmwaregateway I haven't given anyone write access yet. I think this is acceptable for the moment while we check if there are any outstanding issues with the conversion. Please let me know until January 7. If everything is okay by then, I will add write access again and officially move development away from the project-tools SVN repo. Have a good start into 2018! Colin

*PREVIEW* : ReactOS 1st-stage GUI installer testing on Windows

by Hermès BÉLUSCA-MAÏTO

Hello everyone, Lately I was continuing working on my setup_improvements branch: https://github.com/HBelusca/reactos/commits/setup_improvements (whose main purpose, I recall, is to share a maximum of installation code between our working 1st-stage text-mode usetup and our 1st-stage GUI-mode reactos.exe setup that needs to be implemented). The last results of this is that I am now able to install ReactOS files to a user-provided directory using the GUI-mode setup! As Im developing under Windows I tested the file-copying part of the installer (which is, at the time of writing, the latest part of installation code I has been able to share between the two installers) on Windows. You can see the demo here: https://i.imgur.com/xF97hv1.gifv The animated gif also demonstrates the capability of the installer to halt file copying if the user pops the installation-cancel confirmation dialog out; file-copying is resumed when the user does not want to cancel the installation, but it is stopped when the user really cancels the installation. And of course, the file-copying status is displayed with an animated progress-bar. I have worked out a bit the wizard transitions, but some work remains to be done, especially for the partitioning step (currently Im hardcoding in the GUI installer the disk & partition where I want the copy to take place). One can note in the animation that the preparation of the list of files to be copied seems to take a while: indeed, the shared installation code works exclusively with NT paths. However, when this shared code is used in the win32 GUI-mode installer, this code calls inside setupapi.dll functions to manage the installation file queue (in usetup on the contrary, it uses instead a file queue implementation that works directly with NT paths). As a consequence, I need to convert the NT paths back to Win32 ones before feeding them into the setupapi functions, and this is not trivial. I want to improve this conversion by caching some of the computed results. Enjoy! Best regards, Hermès P.S.: Please dont put that on Twitter since this is under heavy work-in-progress and this demo hasnt been done under ReactOS at all.

Postponing December Status Meeting

by Colin Finck

Hi all! If we follow our usual schedule, the December Status Meeting would be today. With such a late announcement and many people still on holidays, I suggest postponing it to next Thursday, January 4, 2018. Time will be 19:00 UTC as always. I already asked on #reactos-dev and got some approvals, so consider this the official meeting invitation :) This also gives you one week from now for agenda proposals. Additionally, we have got some new contributors in the recent months. If you think you should join the meeting or know somebody who should join, please let me know in advance. See you all next year!

Small suggestion for the abandoned SVN mirror on GitHub

by Dmitry D. Chernov

Good day everyone. I'm talking about this repo: https://github.com/reactos/reactos-deprecated-gitsvn-dont-use To prevent pull-requesting to it I suggest to use new GitHub feature "archive this repository". To enable it, just open the "Settings" page and go to the bottom. "Archived" repos are marked as read-only and could not be pull-requested. It's also would be nice to disable unused "Projects" tab in this repo for the great justice of perfectionism. ___ Dmitry D. Chernov

Re: [ros-dev] [ros-diffs] [reactos] 01/01: [NTOS:MM] Fix NtFreeVirtualMemory() FreeType parameter checks. CORE-13126

I'm unsure how reducing the two explicit checks into a single one is a better decision. This is much less scalable and much less clear of what the caller did wrong. I'd like to see the old checks (correctly) restored.

[ros-diffs] [reactos] 01/01: [SDK] pnp.idl: Add a reminder comment about removed Vista/+ functions. CORE-12580

by James Tabor

Hi, Let's try not removing (ZAPPING) API due to future use okay? Just #if it out with the correct __NTZYX__ thing. So if I wish to have VISTA or Server 201X, I can select it while running the configuration script. Do it this way so someone could select Server 2003 (Default now) later on. Same or better TEAM! Think about what will be needed later on. ZAPPING OUT! James

Merging our x86 HALs

by Colin Finck

Hi all, I have been looking into our HALs recently on the promise that it is a huge mess that needs fixing. Well, as a start I could imagine merging our 6 possible x86 HALs (Legacy, ACPI, APIC, ACPI+APIC, SMP, SMP+ACPI) into a single one, even if Windows ships individual ones. I see many advantages of that: * Less duplications and reduced mess: Right now, the APIC HAL hangs at HalpCalibrateStallExecution during boot, a function that has been fixed and universally implemented in all non-APIC HALs. The APIC HAL also duplicates HalpInitializePICs as HalpInitializeLegacyPIC. If you look at the SMP code, it didn't even receive the last build system changes and has conflicting implementations for APIC functions. A single x86 HAL would ensure that all possible configurations are maintained. * Future-proof: How is one going to implement newer features like x2APIC with a structure like that? Would it get another HAL, be integrated into the APIC HAL, or what? We wouldn't have such problems with a single x86 HAL. * Less setup work and testing: Currently, 1st stage setup detects the computer type and installs the appropriate HAL. As such, every additional HAL needs to be added to 1st stage setup code. The user is also able to select a custom HAL during setup, even if it wouldn't work on the machine. We should give neither the user nor the setup the ability to decide. The HAL itself knows best at boot-up what features to enable and what not. * Convenience: The same ReactOS installation could be used on several different x86 computers. So is this the way to go or do I miss something important? Best regards, Colin

Re: [ros-dev] Merging our x86 HALs

by Alex Ionescu

I would move to the Win8+ HAL Model -- a single HAL for APIC, ACPI with runtime support for UEFI (if present) and MP (if present). If people still want to run on a PIC VM (why???) or old computer, then we can also maintain the HAL PIC x86 for UP. Hence there would only be 2 HALs.

RosTests/RosApps in GitHub CI

by Thomas Faber

IIUC we currently always build rostests, but never rosapps in CI. Would it be possible to analyze the changed paths instead and * enable rostests iff modules/rostests/ or sdk/ was changed * enable rosapps iff modules/rosapps/ or sdk/ was changed? That should speed up builds that don't change rostests, while also making sure that changes to rosapps aren't let into master if they break build. If this is nontrivial I may have a look at it myself but someone would need to point me to the right configuration/scripts please. Thanks! -Thomas

Status Meeting (October 2017)

by Giannis Adamopoulos

Hi all! Let me invite you to the monthly status meeting taking place today, October 26, 19:00 UTC. As of now we know that both Colin and Pierre will not be able to attend, or be able to control our IRC server so unless we get any further notice from either of them, the meeting will take place in #reactos-meeting in freenode. No agenda proposals have been submitted to me so far. You are welcome to suggest some points to discuss. One that I would like to propose is about the upcoming release that should be branched soon. Of course we will have our status reports. So please have them ready, so we get it done quickly! Giannis

JIRA up again - Do we still need FishEye?

by Colin Finck

Hi all! Our two Atlassian tools JIRA and FishEye have been unavailable for some hours again. I have brought JIRA back up, but FishEye has been eating RAM and CPU like crazy again. In my opinion, this is unacceptable for a tool that is just a simple commit browser to us. Also I don't have any time to constantly monitor it this weekend, so I'm leaving it shut down for now. With us having https://github.com/reactos/reactos/commits/master and https://git.reactos.org/?p=reactos.git;a=summary now, do we still need FishEye at all? If so, please tell me what features of it you would miss if it stays down. Maybe there are other alternatives. My last FishEye "performance" bug report took 3 months to resolve, and I'm reluctant to go the same route again for another such bug.. Cheers, Colin

Question about commits with no commit log, or commits with no files but just the log, on Git.

by Hermès BÉLUSCA - MAÏTO

‌Hello all,<br> <br> After having noticed https://github.com/reactos/reactos/commit/50ae5e7c5268222718174221366169e2b…<br> I am wondering whether it is possible to add mechanisms (like git pre-commit hooks) that check for, and<br> prevent potential problematic commits like, commits without commit log, or commits with no files (but with a log).<br> <br> Any ideas?<br> <br> Cheers,<br> Hermes

Testing Pull Requests

by Colin Finck

Hi all! Apart from basic build testing through AppVeyor and Travis-CI, you can now also run all regression tests for the code belonging to a Pull Request. Just log in to our BuildBot at https://build.reactos.org with your development account credentials (formerly "SVN credentials"), select a builder in the waterfall view and fill the field "Branch" in the "Force a Build" section. You have two options here: * "refs/pull/<ID>/head" Builds your branch, unmodified. That means, if you haven't kept your branch up to date with the main ReactOS repo, latest changes won't be included. * "refs/pull/<ID>/merge" Builds the changes of your branch merged to the main ReactOS repo. That means, latest changes in the main ReactOS repo will be included. Replace <ID> by the number of your Pull Request. As the resulting hash may be hard to predict, the "prepare source" step will now give detailed information about the latest commit included in your build: https://build.reactos.org/builders/Build%20GCCLin_x86/builds/19201/steps/pr… Have fun!

Sorry for the huge diff E-Mail to ros-diffs! I have just configured git_multimail.py to a maximum of 5000 lines to not let that happen again. We can again reduce the limit later on if it turns out to be still too much. Best regards, Colin Finck

Re: [ros-dev] ReactOS Repository migrated to GitHub

by Can Tasan

Congrats for switching into Github! Just a little question. Is there any way to return using revision numbers? Current hash-based commit tagging might be confusing, hard to find, not reflecting at-the-time state of development since we have relied on SVN for a long time. Also for bug reporting, revision numbers is more helpful. Secondly, for example, Wine don't (and probably won't) care for hashes as everyone out there uses release builds, and release period is just 2 weeks. That's not the case for ReactOS. In just a few commits big changes might occur, and everyone retests. 3 months? Avalanche! If it isn't viable, could we seek for another solution? (e.g timestamp...) Lastly, git.reactos.org is quite simple for watching the stream, and perfect! Best regards, Can

ReactOS Repository migrated to GitHub

by Colin Finck

Today, the ReactOS Source Code has been migrated from a central Subversion instance to a decentralized Git repository. Together with that, ReactOS joins the list of projects using the popular GitHub service for developing software: https://github.com/reactos/reactos We expect that this move greatly improves the way we collaborate on ReactOS development and reduces the barriers for newcomers. Just fork our repository on GitHub, commit your changes and send us a Pull Request! Migrating a source code history of more than 20 years that had seen multiple version control systems was not a straightforward task. Deciding on a decentralized version control system has not been either. First discussions already started back in 2009, when neither Git nor Mercurial were able to fully convert a large SVN repository like ours and Git’s Windows support was still neglected. Things improved massively over the years, with GitHub and Git for Windows emerging as reliable tools for software development. But the ReactOS Project still took advantage of some Subversion features, so only a smooth migration using a two-way SVN-Git mirror was attempted in 2016. This failed miserably, however important lessons were learned for a future complete migration to Git. The tipping point was reached in early 2017 when a majority of ReactOS developers spoke out in favor of moving to Git. Finally, the ReactOS Hackfest in August offered a forum to try out things and discuss every little detail of the planned migration. And this is what got us here today! The development documentation is still in the process of being rewritten to account for the Git migration. You may currently find outdated information here and there. However, most of that is on the Wiki, so you are more than welcome to help us! The SVN Repository has been turned read-only and will be kept online for a while at the last revision r76032. Our Git mirror now mirrors the GitHub repository. If you have already been using our old Git mirror, please note that you have to do a fresh clone of our new repository (from either GitHub or the mirror) as the old and new ones are incompatible. JIRA continues to be used for bug tracking, BuildBot for continuous integration, and FishEye as a code browser. I would like to thank all the people who have helped with this migration, be it on IRC, the mailing lists or at the Hackfest! Special thanks also go to the KDE Project for their excellent svn-all-fast-export tool that was used for the conversion. If you are ever in a similar situation, have a look at my conversion scripts as well as the Git helpers for our infrastructure. Colin Finck

Regression in r75772 broke multiple disk drive support

by Dimitrij Klingbeil

Hi all, It looks like revision 75772 (removed a "DeviceExt->OpenHandleCount--;") has introduced some significant unintended consequences. Ever since I can't get ReactOS to recognize a second hard drive. My configuration is like this: - ReactOS in a VirtualBox VM, VirtualBox version 5.11.18 - VM configured for Windows 2003 32-bit, with 1 CPU - Emulated Chipset: PIIX3, no USB, no Audio, no Serial - AMD-V active, Nested Paging active, - No paravirtualization interface, no guest additions - Emulated Storage: SATA controller with 4 ports - Port 0: First Hard disk (has partition C) - Port 1: Second Hard disk (has partition D) - Port 3: CDROM (to install ReactOS from, E) - Each hard disk has one single primary partition (FAT formatted by an older ReactOS setup) - On C I install ReactOS (re-formatting the partition in the process) - On D there is some data (a small collection of program installers to try out) Now, inside ReactOS I cannot see the contents of D. The drive itself shows up, but unformatted and of a zero size. In the revisions before 75772 there were no problems, I could see the drive and use the data on it. Re-installing r75771 shows that the drive image is OK and the data is still there, so it's not the data that was corrupted. If I insert a CDROM image (with ReactOS already running), the CDROM drive (E) suddently disappears and D now has the CDROM in it (so happened just now with r75872). When I eject the CDROM, D becomes empty but still shows the icon for a CDROM. E does not re-appear. 75772 looks like a very small change, but something must have gone really off the rails... Regards, Dimitrij P.S. This was at first sent from the wrong (not subscribed to the list) address by mistake. I think the first one was rejected by the list SW, but sorry if the message appears twice.

Status Meeting (September 2017)

by Colin Finck

Hi all! Let me invite you to the monthly status meeting taking place today, September 28, 19:00 UTC. As always, you will get credentials for our private IRC server shortly before the meeting. No agenda proposals have been submitted to me so far. If that doesn't change, we will have a meeting just for the status reports. Please have them ready, so we get it done quickly! A lot of tasks from our long last meeting are also still in progress (not just the Git migration), so I wouldn't mind having a short meeting this time. See you in a few hours! Colin

Git Migration on October 3!

by Colin Finck

Hi all! With our infra/toolchain now being fully prepared for the Git migration, I can finally say that there are no more blockers holding us back. Therefore I'm announcing that the migration from SVN to Git will take place on TUESDAY, OCTOBER 3, 2017 During that day (European time) SVN will be turned read-only forever and some of our services may expect temporary downtime. Let's see who will get the last commit ever to SVN :) The new repository will then be available at https://github.com/reactos/reactos, with https://git.reactos.org providing a mirror. The following things are still on the To-Do list, but I don't consider them blockers. We can work on them iteratively after the migration: * Writing a new .gitignore file. * Writing a .gitattributes file to enforce EOL style. * Writing Git guides on our Wiki for beginners and SVN users. Best regards, Colin

Re: [ros-dev] Regression in r75772 broke multiple disk drive support - format also does not work

by Dimitrij Klingbeil

Something else seems to be off the rails too... It does't seem possible to format the drive from within ReactOS either. Here's what happens when I try the command-line format utility: - Fill drive D with enough stuff (to see a clear size difference) - Start cmd.exe, then "Format D: /Q" - Format appears to run, writing a new FS - At the end, Format will display a drive size summary - The "used" size is wrong, the drive is still as full as before (!) - When going there with Explorer, the contents have not disappeared (!) - The FS structure seems to be messed up however, as - after a reboot the drive is no longer there (not raw but missing) It looks like Format does not properly unmount the drive before formatting and / or it does not re-mount it after formatting either, or at least that these steps somehow fail to work. The result seems to be a corrupted FS. However I'm not sure if formatting has ever worked - never tried before.

Rethinking our Git merge workflow

by Colin Finck

Hi all! After playing around with GitHub's features in https://github.com/colinfinck/sandbox for the last few days, it turns out that its server-side settings hardly prevent repository mess. Although I have set master to be a "protected branch" and enabled the option "Require branches to be up to date before merging", it allows me to push just everything that doesn't rewrite history. This includes any kind of merge commits, even the nasty automatic merges that occur when you commit to your outdated local master and then do the requested "git pull" before pushing. GitHub Staff confirmed to me that GitHub has no way of enforcing a rebase-only workflow. For a self-hosted Git, a simple pre-receive hook like https://stackoverflow.com/a/5493549 would do the trick. The only other option GitHub offers is requiring each commit to go to a branch. Changes to master can only happen through an approved Pull Request then. This would drastically change our workflow though, and I don't think we want this additional burden for every minor change. Before we now reverse our decision for a GitHub master repo, let's verify that a self-hosted Git repo with an enforced rebase-only workflow is really what we want: - It would ensure a linear history in the "master" branch, just like WINE has. If you sort by "Commit Date" instead of "Author Date", the history would even be chronological. - When contributing changes from a branch back to "master" using "git rebase", every single commit is reapplied with a new hash. Except for the author dates, these commits have no link to the original branch. - Without GitHub as the master repo, we would lose the ability to merge Pull Requests directly from the website. That would sooner or later turn the entire Pull Request feature of GitHub useless for us. Contrary to what people told me, GitHub doesn't detect when you merge the Pull Request locally and push these changes back to GitHub. On the other hand, what would an unrestricted GitHub provide us: - Discussing, improving, and later merging Pull Requests directly on the website. Merging, squash merging, and rebase merging is supported. Not just for our own branches, but also for forks of the ReactOS repo. - Our history graph in the "master" branch will inevitably become a stream of parallel lines, making it harder to follow the history chronologically. Worst-case example is the Linux kernel: http://fs5.directupload.net/images/170914/h5pddxx7.png (ok, admittedly gitk renders this graph a bit nicer) Allowing merges used to be an even bigger problem when we still wanted a linear history to replicate SVN revision numbers. But we now replaced revision numbers by the output of "git describe". So maybe merge commits are ok now? At least, we should be able to prevent automatic merge commits by instructing every committer to use "git fetch && git rebase origin" instead of "git pull" when syncing with the server. A nicely written and illustrated (Tortoise)Git guide on the Wiki should do the job :) I tend to favor the second option right now and allow merges, but I definitely need more input on this from you. Best regards, Colin

Git Migration Newsletter #2

by Colin Finck

Hi all! Let me give a short update on the Git Migration: * The data from the committer table has been converted into an identity map for the SVN->Git conversion tool: https://github.com/ColinFinck/reactos-git-conversion-scripts/blob/master/re… Together with my hacked version of svn-all-fast-export (https://github.com/ColinFinck/svn2git), this results in a really nice and clean Git repo :) Further changes to your names or E-Mail addresses in that committer table won't be taken into account. Please add your GitHub usernames to that table though! * As you can imagine, our tree and tools need several changes to deal with the change from SVN revision numbers to Git commit hashes. My first patch for reporting the "Git revision" in our codebase is ready and open for discussion: https://github.com/ColinFinck/reactos-git-conversion-scripts/commit/0aaa6ff… More to follow! Cheers, Colin

Git Migration Newsletter

by Colin Finck

Hi all! Let me give a public update about our Git Migration Decisions after the last meeting: * The migration of our SVN repository "reactos" is going to happen in September/October. * https://github.com/reactos/reactos will become our master repository as we want to take advantage of GitHub's Pull Request features. This means, all developers must register for GitHub accounts now. * git.reactos.org will remain as a replication slave. If we ever have severe problems with GitHub, we can switch back to a self-hosted Git in no time. * We will enforce a linear history in the "master" branch through server-side GitHub settings. You may create and push as many branches as you want and do whatever you want there, but when you want to commit the changes back to "master", you can only do so over a "git rebase". * BuildBot builds will get a naming scheme like: reactos-bootcd-0.4.7-dev+344-5f3c53e2a-gcc.7z That means 344 commits after the tag "0.4.7-dev" has been created, with this particular commit having the short hash "5f3c53e2a". Whenever we branch for a release like "0.4.6", we will now not just create the branch, but also tag "master" with "0.4.7-dev" to make this naming scheme possible. More newsletters like this may follow when I have more information to share or get the impression that some decisions haven't reached all developers yet. Best regards, Colin

Git Migration: The documentation, rossubsys and wallpapers directories

by Colin Finck

Hi all! As you know, we have to give up our "modules" directory concept when switching to Git, because Git doesn't support checking out an arbitrary directory into a subdirectory of a Git clone. Therefore, the first commit to the migrated repository will make the "reactos" directory the new root and move "rosapps" and "rostests" permanently into "modules". We can then introduce an environment variable/CMake variable/something else to enable or disable building of them on demand (suggestions are welcome!) But what will happen to the remaining directories in /trunk, namely "documentation", "rossubsys", and "wallpapers"? * Commits to "documentation" never had a relation to "reactos" commits, so nothing is lost if we put that directory into a separate repo "documentation.git" and remove all traces to it from the history of "reactos.git". I'd go this way if there are no objections. * I don't get the idea of that "rossubsys" directory created in 2014.. These subsystems are all stubs, never built with modern ReactOS, and no work has happened since "reviving" them. I would just go and remove them again. You can always find them in our repository history. * The "wallpapers" directory is a harder candidate. On the one hand, we don't want to bloat our ReactOS builds by including wallpapers in every build. Also the number of wallpapers may increase in the future, which could bloat the "reactos.git" repo even more. On the other hand, the wallpapers have always accompanied our release branches, so there is a value of having them tracked next to our code. I could put them in a separate repository "wallpapers.git" now and remove all traces to them in the "reactos.git" repo. But then again, how are they picked up by the build process in the future if we can't check them out into a subdirectory of "modules"? Another alternative is moving them to "modules/wallpapers_disabled". Then they are not picked up by the build process until they are renamed to "modules/wallpapers" for releases. What are your opinions on this? Cheers, Colin

Re: [ros-dev] [ros-diffs] [cfinck] 75630: [FS_REC] - Add a detection routine for CDFS (ISO-9660) volumes that verifies the Primary Volume Descriptor. - Use this to also detect CDFS on disks and load the CDFS driver if it ha...

by Pierre Schweitzer

Hi Colin, Thanks for your work. This commit is likely breaking UDFS recognition when media has a protective CDFS partition with UDFS afterwards, while both FSD are unloaded. You'll first match the CDFS recognizer and not the UDFS recognizer. I would suggest you modify FsRecRegisterFs() so that you can register low priority FS.

Re: [ros-dev] [ros-diffs] [cfinck] 75586: - Add 0x96 as ISO9660 partition type to ntdddisk.h (from https://en.wikipedia.org/wiki/Partition_type) and detect it using IsRecognizedPartition. - Make our isohybrid create an MBR ...

by Alex Ionescu

This is cool work but you do realize that adding non-Windows partition types and changing Windows headers (and Windows macros) to work with them, as well as forking our CDFS from the Windows CDFS... doesn't really help compatibility move forward... It would be nice to discuss about how these changes can be done to keep our 'special' USB livecd boot and CDFS changes, without twisting the system away from its NT roots. My suggestion would be a filter driver on top of CDFS, and a re-definition of this macro to be used by the filter (or whatever code relies on it). This sounds like it would give you the best of both worlds...

Licensing - Make ReactOS conform again!

by Colin Finck

Hi all! I've held a presentation at Hackfest today regarding Licensing Best Practices, different positions about the GPL and its influence, and ways to improve ReactOS' conformance with all involved licenses. I think we should treat this subject even more seriously than others, given that we are an Open-Source project trying to provide an alternative to a proprietary product. Also licensing questions arise from time to time, which is why we should collect some answers. Please watch the video at https://youtu.be/OTVVz9VLisU or see the slides at https://svn.reactos.org/press-media/trunk/Events/2017%20-%20Hackfest/Licens… Discussions are open now! :) But if there are no objections, let's introduce SPDX license headers, .ABOUT files, and a complete license list as soon as possible. Cheers, Colin

Summer of Code ends next week, so you are welcome to join the Code Review at https://code.reactos.org. I guess CR-122 will be shortly updated with the latest changes there. Let's try to not duplicate efforts here ;) Best regards, Colin

ReactOS now listed in AppDB

by Erkin Alp Güney

I have recently added ReactOS as a distribution into Wine Application Compatibility database as ReactOS uses most of Wine components. ReactOS-Windows incompatibilities can now be tracked like Wine-Windows incompatibilies.

Re: [ros-dev] Modularizing the ReactOS repo in Git

by Alex Ionescu

I would strongly suggest using one master repo. Multi-repo projects and their brethren are a mess.

Re: [ros-dev] Modularizing the ReactOS repo in Git

Modularizing the ReactOS repo in Git

Enabling themes in 3rd stage

by Giannis Adamopoulos

Hello, After recent changes in explorer, comctl32 and uxtheme the state of themes in reactos was improved a lot. I would like to ask your opinions about enabling themes in 3rd stage. It is also possible to have an option in 2nd stage to select if we want 3rd stage to have themes enabled. Do you think this should be enabled by default or not? All ideas are welcome. My intention is to complete it ASAP so that it can make in the release. Thanks, Giannis Adamopoulos

Another Hackfest update

by Colin Finck

Hi all! With the Hackfest less than 3 weeks away, let me give you another status update: * It is important that you now add yourself to https://reactos.org/wiki/ReactOS_Hackfest_2017/Lists or fix up your information there. Further E-Mails will only go to the people listed there. * As many of us also attend FrOSCon on Saturday and Sunday (19-20), I'm also going to book the loft for this night. There may be options closer to FrOSCon, but I think not having to hastily check out early on Saturday with the entire equipment outweighs the 1 hour trip between the loft and FrOSCon. * The Ideas list looks very promising. In order to make the most out of the Hackfest, preparations should begin now. For example, I really want the Git move to happen in October, so let's not hesitate with all necessary source tree restructuring and testing. There has been no meeting announced for tomorrow, so I'm unsure whether we will have one. In case we do, let's handle any outstanding questions tomorrow. Cheers, Colin

About ATL wrappers - atlex

by Alexander Sh.

Hello, I am sanchaez (Alexander Shaposhnikov) - a GSoC student working on RAPPS. I've found a set of useful wrappers for ATL on Github - https://github.com/Amebis/atlex. I have some questions: 1. It is GPLv3. Is it compatible with ROS license? Can I use them? 2. If I can, where to place it in the source folders? P.S. I've rushed a little by committing it to my branch. "It lies in reactos\sdk\include\reactos" for now. Thanks in advance, Alexander

Ethereum for fundraiser

As the first flight to the Hackfest has been booked today, I have clarified the dates on https://reactos.org/wiki/ReactOS_Hackfest_2017 I will book the loft also for the night from Sunday to Monday (August 13 to 14), so you have the option to arrive earlier and the Hackfest can definitely begin on Monday.

About the bootcd and livecd, and the 1st-stage GUI setup

by Hermès BÉLUSCA-MAÏTO

Hello everyone, One of the long-term plan for ReactOS was to have a graphical user-mode interface for the 1st-stage setup, similar to e.g. what may be found in newer versions of Windows (Vista+), as an alternative to our current 1st-stage setup in text-mode (note that I say alternative, not replacement, because both of them can live together without fundamental changes to either ReactOS or our ISO images, both of them can share core functionality, and finally because some people may prefer the text-mode either for unattended installations or for low-memory conditions). You can find some information about the 1st-stage GUI setup here: https://reactos.org/wiki/First_Stage_GUI_Setup . In our source code, it can be found in base/setup/reactos/ . Currently only most of the screens have been implemented, while the core functionality is not present. However this functionality can somehow be taken by reusing the source code of USETUP (see my branch https://svn.reactos.org/svn/reactos/branches/setup_improvements/base/setup/ ). Abstract (aka. TL;DR): I explain below the needed changes introduced experimentally in the setup-improvements branch, revision 75273, to generate an all-in-one ReactOS bootcd, that includes both the 1st-stage text-mode setup + 1st-stage GUI setup alternative + live-demo functionality. This is meant to replace our currently separated bootcd / livecd ISOs, where the latter currently do not offer the possibility to install ReactOS. Some currently known potential problems are evoked. Images: Proposed BootCD contents : http://i.imgur.com/EBA6JHd.png ; Proposed Boot Menu : http://i.imgur.com/14n5Ryi.png . Having a 1st-stage GUI setup also means that itll also use the already-existing functionality that we offer in our Live-CD ISOs. Currently, the Live-CD ISOs we provide only allow for demonstration purposes, while the ReactOS installation proper is found in our so-called Boot-CD ISOs (which currently only contain text-mode setup). Thus, the 1st-stage GUI setup, as an alternative to the 1st-stage setup in text-mode, means that both ISOs can be merged all in one, and we wont have to make a distinction between both: they will be able to offer both the 1st-stage in text mode AND a graphical mode (à la Live-CD) where it is possible to choose whether to test ReactOS in demo mode, or to install it via the GUI setup. Such an all-in-one ISO capability was already present in the trunk under the name hybridcd, but was used only when we built ISO images for the public events where ReactOS participated (FOSDEM, CLT, ). But now, having the setup process both in text mode and in graphics mode, in addition to the Live-CD demonstration capability, really suggests just using the all-in-one ISO and stop doing the Boot-CD (aka. only setup) vs. Live-CD (aka. only demo) separation. We would just generate only one type of ISO that contains everything. With that in mind, I have committed in my branch setup_improvements, in revision 75273 : https://svn.reactos.org/svn/reactos?view=revision <https://svn.reactos.org/svn/reactos?view=revision&revision=75273> &revision=75273 such changes to be able to only build an ISO that contains everything. These changes are minimal, in the sense that I havent purposelessly changed the names of the build targets just to be fancy. Such changes may be done later, but not now. The needed changes are the following: First, the build target that will generate the all-in-one CD is called bootcd, because this also was the main build target for ISOs before the change. Second, I completely remove the hybridcd build target, because its functionality are now absorbed by bootcd. Third, the build target livecd is reduced to its strict minimum. For the sake of building a RAMDISK boot drive (see comments after), I continue to generate an ISO for livecd. But Ive changed the generated name to liveimage.iso, to emphasize the point that it has to be understood as a (virtual) disk image for RAMDISK purposes, not just as a ISO image. Note that I havent renamed the build target livecd to, say, liveimage to reduce my commit changes (such a renaming may be done later). The livecd target builds a list of files that need to be present in the image. The generated liveimage.iso is no-more a bootable ISO, Ive removed inclusion of freeloader + El-Torito boot-sector + the USB-ISO-Hybrid functionality for it. The bootcd target has been slightly changed in order to include the liveimage.iso as a file (for RAMDISK), and to also add the contents of this image in a flattened tree within the bootcd iso: the two directories Profiles and reactos. The 1st-stage text-mode setup is kept, as said before, but its corresponding files + the installation CAB source + the 1st-stage GUI setup application proper goes into a (renamed) directory called i386, corresponding to installation files for an i386 installation (technically, 1 per architecture when well have a ReactOS ported to other archs). These files cannot be present in the same reactos directory as the ones from the flattened LiveImage, because some of the files are different (smss.exe, registry, etc) Our FreeLdr knows from where to boot the 1st-stage text-mode (from i386), as well as the Live-demo in graphics mode (from reactos). I need to adjust the code of few setup components for them to stop relying on hardcoded reactos/ path, and instead use a more dynamic (determined at runtime) path. NOTE FOR DEVS/SYSADMINS: The bootcdregtest build target, generating the special ISO that is fed to our test bots, remains exactly the same, and the files contained in the generated ISO have not changed. NOTE about the RAMDISK feature: I enabled it so that a user can remove the demo media (CD, ) and reuse the drive for other purposes, while still being able to use ReactOS. Of course this requires a large amount of RAM available. And thats also why I include the flattened liveimage files so that one can use the demo without the RAMDISK (when few memory is available). As is currently implemented, this makes the ReactOS all-in-one bootcd large (it gains a good 100 MB) due to duplicated space (the flattened files, plus the same inside liveimage.iso). I cannot do better (unless ditching either the RAMDISK, or keeping it but not include the flattened files) because ReactOS currently doesnt have a way to boot from disk images *that are not meant to be a RAMDISK*. The day when this difficulty is removed, a single disk image could be used either as the RAMDISK or the (non-removable) installation. A second remark is that I dont plan to have the 1st-stage GUI setup available when booting ReactOS in RAMDISK mode because, as a consequence of its current implementation, I would otherwise need to duplicate the installation CAB source in the RAMDISK image too, making it again larger. NOTE about the FreeLdr Boot Menu: Since ReactOS is not that stable currently, we like to boot it in debug mode, and redirect the output to a serial port (usually COM1). However some people dont have serial ports on real hardware, so we propose to boot with debug output redirected to screen. However this may slow ReactOS down, so we also like to boot ReactOS with debug mode disabled. Thats why I proposed the declination of these boot modes for each ReactOS installation contained in the BootCD (Live+Setup, with or without RAMDISK, and with debug enabled or not). The problem is that it clutters a lot the boot menu. A remedy would be to implement in FreeLdr the functionality of editing *existing* boot entries to change their associated boot options, so that one could add by hand the options to enable (or disable) debugging. This is currently unimplemented. The only implemented feature is to set up a new boot entry on the fly to boot ReactOS afterwards. NOTE for regress-testers: Possible remark that I may hear: I only care about installing ReactOS (perhaps just in unattended mode) and I dont care at all about the GUI setup nor about the Live-demo thingie, and your new BootCD is too large. I want to be able to download & use the good-old bootcd for regress-testing. . So what to do? Since we currently build and store the bootcdregtest ISOs, but are not publicly available through our www.reactos.org/getbuilds interface, I would suggest here to make them available to people, so that those who want to quickly DL and/or install/regress-test ReactOS could use these ISOs instead (which are really just the good old BootCDs, but with unattended installation enabled *and* with our test-suite included). They are not that much large, just a bit more than the old regular bootcd. Please let me know whether you have other remarks/comments/questions/suggestions/etc to make the new BootCDs better. Best, Hermès

Status Meeting (June 2017)

by Aleksey Bragin

Hello, Let me invite you to the monthly status meeting taking place 29th of June, 19:00 UTC. We do it either in #reactos-meeting on Freenode, or on a very own standalone IRC server. In that case your participation passwords and server address will be emailed to you shortly before the meeting starts, and they are going to be different once again as they are not stored in any database. And everyone is fine with that. Please send agenda proposals to me before the meeting so we don't waste time trying to setup the agenda directly during the meeting. Regards, Aleksey Bragin

SVN url change?

by Hermès BÉLUSCA-MAÏTO

Hello all, Today I noticed that our buildbots couldnt connect to SVN to upload the commit changes, and therefore failed to build. Also I noticed that the usual SVN ViewVC address (which was previously https://svn.reactos.org/svn/reactos , for example) changed to https://svn.reactos.org/viewcvs/reactos/ (granted, there appear to be an automatic redirection to this new address). Is it an intentional change, or an unintentional one? We didnt seem to be warned prior to this on the mailing list! Cheers, Hermès

ReactOS Hackfest 2017 - Are you in?

by Colin Finck

Hi all! I'm currently planning the ReactOS Hackfest 2017 in the Cologne/Bonn area in Germany. Currently, the plan is to book a meeting room from Monday, August 14 to Friday, August 18. We can then use the weekend before to get to Cologne and explore the city a bit. After the Hackfest, everybody interested can join us at FrOSCon in Bonn the weekend after. As booking a room there involves significant costs, I'd like to know who of you can definitely make it for the Hackfest and who of you is definitely out. Please reply now to prevent me from bugging you on IRC all the time! ;) Cheers, Colin

I have implemented short and simple WineTest-compatible client/server code in localspl_apitest. The server is the application that is tested through rosautotest. For every test, it starts the client, sends the test name over a pipe and outputs the received testing output. The client simply has stdout redirected to a pipe and can then use usual WineTest ok() functions for testing. Check out rostests/apitests/localspl (server) and rostests/apitests/localspl/dll (client). Hope that helps! - Colin

GPU testing machine is ready!

by Colin Finck

Hi all! A picture says more than a thousand words: http://fs5.directupload.net/images/170613/u4d8a59a.png As promised in the last meeting, I have brought to life a machine for testing GPU drivers with real GPUs under ReactOS. It combines a QEMU virtual machine with PCIe GPU Passthrough together with a KVM-over-IP card for feeding the real video signal back to a window. What you see in the screenshot is a real NVIDIA GeForce 9300 GPU attached to a ReactOS VM. We can now test the NVIDIA driver installation while enjoying the easy debuggability of a VM. My first report is already out: https://jira.reactos.org/browse/CORE-13423 Every developer interested in working on this can drop me a line and I will send you credentials for the server. Soon I will also add an AMD Graphics Card along with another KVM-over-IP card to let us debug the other big driver package. Thanks go out to Mr. Kromdijk for the generous server donation, Christoph for the KVM-over-IP card, and Hervé for the QEMU hints! Let's all get some flashy 3D acceleration into ReactOS!! :) Cheers, Colin

I understand not making the change to how 1st stage deals with the registry in trunk. Why not the tool change though? Can't you have the new mkhive do the exact same thing it does now, and do it in trunk? The smaller your branch merge commit the easier it will be to avoid/pinpoint/fix regressions.

What is that supposed to even mean? "I was too lazy to test this"? "All the other code depends on this leak"? "I think it would look prettier here"?

mplayer -- branded name?

by Javier Agustìn Fernàndez Arroyo

Hey guys, An idea has just come to my mind, mplayer is an application that already exists for Linux: https://www.mplayerhq.hu/design7/news.html maybe we should change ReactOS´ player name so that we avoid possible future demands? what do u think?

I have visited a seminar by our friend Nuno Brito last week, who has founded a company that deals with such topics (www.triplecheck.tech). There are some simple best practices we can apply here to get consistent and useful headers once and for all. The first would be using the established SPDX license identifiers from https://spdx.org/licenses (here: "GPL-2.0+"). This would also make our source files easily scannable by tools to get an overview of all licenses involved in our code and imported third-party components. If you or someone else is interested in working on this, let's draft a universal header for our files that is compatible with SPDX. Otherwise, I will have a look when there's more time..

A surprising epic win: Wolfram Mathematica on ReactOS

by Hermès BÉLUSCA-MAÏTO

Hi all, I was pleasantly surprised to notice that the symbolic computation program « Wolfram Mathematica », in its version 8.0.4 (later versions are for Vista+ only), actually works quite pretty well on ReactOS (as of r74550): see the screen-capture at http://i.imgur.com/KegyW79.png . This software is broadly used in many scientific, engineering, mathematical, and computing fields. This is for example used intensively in theoretical physics (in high-energy physics, statistical physics etc.) due to the existence of numerous packages that have been developed for it. The only problem of this software resides in its price On the screen-capture I demonstrate an infinitesimal portion of what Mathematica can do: for the non-connoisseurs :) the picture shows the computation of the integral (area under the curve) of the 1-dimensional Gaussian function over the whole real axis (the result is square-root of pi), and then I plot in 3 dimensions the map of a 2-D Gaussian function, where on the horizontal plane there are the x and y axes, and the vertical axis is the z axis. The 3-D graph can be rotated, zoomed-in and out with the mouse, it can be edited, etc The software also proposes an extensive and interactive help documentation. Finally I show the fancy text-mode only interface of Mathematica, that nobody actually uses (it is only used when computing stuff in batch-mode). There are almost no graphical glitches. Few font problems can be seen (see the about-box, and the minus signs on the graph replaced by boxes). There are few keyboard shortcut problems such as pressing (on French keyboards) AltGr-5 to enter [ doesnt work, but anyways Enjoy! Best, Hermès

About the recent USETUP improvements in the branch

by Hermès BÉLUSCA-MAÏTO

Hi all, Im writing a short mail to explain the recent USETUP improvements Im 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

We have a bin2c tool that would make including the boot logo much nicer. You'll want to use something like the attached patch, and add the bmp file as app/rosload/logo.bmp. Then just include "logo.h" instead of the g_Logo array in rosload.c.

Hey Hermès, I'm fixing how the BCD hive is generated and this just showed up in an svn blame for me. Can you explain why this bcd_hive dependency is needed? I don't see the command depending on the hive file.

Re: [ros-dev] Microsoft switched to Git

by Alex Ionescu

Sounds like a bug in their migration/etc tool. MS has history going back to 1984 and migrated everything to Git with zero problems. At some point you should apply Ionescu's Razor: "Hmmm, a company of 150,000 developers and the most complicated and oldest series of repositories in the world, was able to move to Git, including while employing people who have been there for 30 years and used to other, older systems.... but 30 open source developers can't make that change because X". It follows from this that X is bullshit. On the polluting history, again, just read commits that have [FOOBAR] in them, and ignore others. Write a post-commit hook to rewrite/squash them.

ReactOS is the MOST VOTED project in the "Best IT Community" category in the #OpenAwards

by victor martinez

Congrats Community! You did it!! Thanks to your votes casted, ReactOS is finalist in the "Best IT Community" category. Even more! ReactOS was the MOST VOTED project in such category! https://a.cstmapp.com/p/18092?fromgroup=1 ReactOS: 229 votes 2nd. KeepCoding: 190 votes As you may know, ReactOS was also trying to be finalist as the "Best Innovative project". We were literally just ONE vote away to be one of the five finalists. 202 casted, 203 needed. https://a.cstmapp.com/entries/18085/sort:votes/direction:desc So even if we weren't finalist it in this category I want to thank in name of the ReactOS project all your help, votes, and support to make it possible. Our strategy of waiting until last minute helped us to overtake and surprise really big and amazing projects as the Drupal Association, Geo developers or gvSig, but also projects supported/created by well stablished companies and public governments. Thanks Community! We'll keep you updated! More info soon as a blogpost! Víctor Martinez Calvo ReactOS PR & Product strategy coordinator

Re: [ros-dev] [ros-diffs] [gadamopoulos] 74457: [UXTHEME] -Use GdiDrawStream in UXTHEME_DrawImageGlyph and UXTHEME_DrawImageBackground.

Hi, Why not use constant for 0x44727753 and rename unknown1 and unknown2 to srcImageType and dstImageType (or something similar) and use defines for these types also 1 = OriginalImage, 9 = NineGridImage (or similar). This will make code a little bit less magical :) IMHO BR, Peter > On May 3, 2017, at 14:13, gadamopoulos(a)svn.reactos.org wrote: > > Author: gadamopoulos > Date: Wed May 3 11:13:23 2017 > New Revision: 74457 > > URL: http://svn.reactos.org/svn/reactos?rev=74457&view=rev > Log: > [UXTHEME] -Use GdiDrawStream in UXTHEME_DrawImageGlyph and UXTHEME_DrawImageBackground. > > Modified: > trunk/reactos/dll/win32/uxtheme/draw.c > trunk/reactos/dll/win32/uxtheme/uxthemep.h > > Modified: trunk/reactos/dll/win32/uxtheme/draw.c > URL: http://svn.reactos.org/svn/reactos/trunk/reactos/dll/win32/uxtheme/draw.c?r… > ============================================================================== > --- trunk/reactos/dll/win32/uxtheme/draw.c [iso-8859-1] (original) > +++ trunk/reactos/dll/win32/uxtheme/draw.c [iso-8859-1] Wed May 3 11:13:23 2017 > @@ -269,163 +269,6 @@ > return S_OK; > } > > -/*********************************************************************** > - * UXTHEME_StretchBlt > - * > - * Pseudo TransparentBlt/StretchBlt > - */ > -static inline BOOL UXTHEME_StretchBlt(HDC hdcDst, int nXOriginDst, int nYOriginDst, int nWidthDst, int nHeightDst, > - HDC hdcSrc, int nXOriginSrc, int nYOriginSrc, int nWidthSrc, int nHeightSrc, > - INT transparent, COLORREF transcolor) > -{ > - static const BLENDFUNCTION blendFunc = > - { > - AC_SRC_OVER, /* BlendOp */ > - 0, /* BlendFlag */ > - 255, /* SourceConstantAlpha */ > - AC_SRC_ALPHA /* AlphaFormat */ > - }; > - > - BOOL ret = TRUE; > - int old_stretch_mode; > - POINT old_brush_org; > - > - old_stretch_mode = SetStretchBltMode(hdcDst, HALFTONE); > - SetBrushOrgEx(hdcDst, nXOriginDst, nYOriginDst, &old_brush_org); > - > - if (transparent == ALPHABLEND_BINARY) { > - /* Ensure we don't pass any negative values to TransparentBlt */ > - ret = TransparentBlt(hdcDst, nXOriginDst, nYOriginDst, abs(nWidthDst), abs(nHeightDst), > - hdcSrc, nXOriginSrc, nYOriginSrc, abs(nWidthSrc), abs(nHeightSrc), > - transcolor); > - } else if ((transparent == ALPHABLEND_NONE) || > - !AlphaBlend(hdcDst, nXOriginDst, nYOriginDst, nWidthDst, nHeightDst, > - hdcSrc, nXOriginSrc, nYOriginSrc, nWidthSrc, nHeightSrc, > - blendFunc)) > - { > - ret = StretchBlt(hdcDst, nXOriginDst, nYOriginDst, nWidthDst, nHeightDst, > - hdcSrc, nXOriginSrc, nYOriginSrc, nWidthSrc, nHeightSrc, > - SRCCOPY); > - } > - > - SetBrushOrgEx(hdcDst, old_brush_org.x, old_brush_org.y, NULL); > - SetStretchBltMode(hdcDst, old_stretch_mode); > - > - return ret; > -} > - > -/*********************************************************************** > - * UXTHEME_Blt > - * > - * Simplify sending same width/height for both source and dest > - */ > -static inline BOOL UXTHEME_Blt(HDC hdcDest, int nXOriginDest, int nYOriginDest, int nWidthDest, int nHeightDest, > - HDC hdcSrc, int nXOriginSrc, int nYOriginSrc, > - INT transparent, COLORREF transcolor) > -{ > - return UXTHEME_StretchBlt(hdcDest, nXOriginDest, nYOriginDest, nWidthDest, nHeightDest, > - hdcSrc, nXOriginSrc, nYOriginSrc, nWidthDest, nHeightDest, > - transparent, transcolor); > -} > - > -/*********************************************************************** > - * UXTHEME_SizedBlt > - * > - * Stretches or tiles, depending on sizingtype. > - */ > -static inline BOOL UXTHEME_SizedBlt (HDC hdcDst, int nXOriginDst, int nYOriginDst, > - int nWidthDst, int nHeightDst, > - HDC hdcSrc, int nXOriginSrc, int nYOriginSrc, > - int nWidthSrc, int nHeightSrc, > - int sizingtype, > - INT transparent, COLORREF transcolor) > -{ > - if (sizingtype == ST_TILE) > - { > - HDC hdcTemp; > - BOOL result = FALSE; > - > - if (!nWidthSrc || !nHeightSrc) return TRUE; > - > - /* For destination width/height less than or equal to source > - width/height, do not bother with memory bitmap optimization */ > - if (nWidthSrc >= nWidthDst && nHeightSrc >= nHeightDst) > - { > - int bltWidth = min (nWidthDst, nWidthSrc); > - int bltHeight = min (nHeightDst, nHeightSrc); > - > - return UXTHEME_Blt (hdcDst, nXOriginDst, nYOriginDst, bltWidth, bltHeight, > - hdcSrc, nXOriginSrc, nYOriginSrc, > - transparent, transcolor); > - } > - > - /* Create a DC with a bitmap consisting of a tiling of the source > - bitmap, with standard GDI functions.

New ideas added to GSoC Ideas list

by Colin Finck

Hi all! Daniel and me collected some additional ideas for GSoC today, which I've added to our Wiki Ideas list: https://reactos.org/wiki/Google_Summer_of_Code_2017_Ideas In particular: * Fundamental WiFi components * USBXHCI driver for supporting USB 3.x controllers * Bluetooth Stack * WebKit-based MSHTML implementation I'm open for comments and suggestions! We can still add ideas until March 20, so let's give students a large pool to draw from. Cheers, Colin

Status Meeting (April 2017)

by Aleksey Bragin

Hello, Let me invite you to the monthly status meeting taking place 27th of April, 19:00 UTC. We do it either in #reactos-meeting on Freenode, or on a very own standalone IRC server. In that case your participation passwords and server address will be emailed to you shortly before the meeting starts, and they are going to be different once again as they are not stored in any database. And everyone is fine with that. Please send agenda proposals to me before the meeting so we don't waste time trying to setup the agenda directly during the meeting. Regards, Aleksey Bragin

retiring 'shellext/slayer'

by Mark Jansen

The shell extension 'slayer' will soon be removed. It has been surpassed by the shell extension 'acppage'. Since neither of the modules is yet active, this should not pose a problem. Related issues: CORE-10375 and CORE-13111 Regards, Mark.

Test KVM AHK Bot Upgrade

by Sylvain Petreolle

Hello all, I'm currently upgrading my AHK Testbot to Fedora 25, 24 only receives backports and Fedora 26 is already on the way. I never upgraded it before, so I don't know if it will take one or several hours to be back online. Kind regards, Sylvain Petreolle

That's a good idea and makes sense for the bootcd-dbg ISOs.

Building/Testing infrastructure back on steroids!

by Colin Finck

Hi all! As of today, our high-performance servers Carrier, Mothership and Testee are finally back in service for building and testing! They take over many tasks from HotelLux, the generously provided server from Aleksey, which had to bear the load of previously 3 separate machines for over a year. You should notice faster builds on the Windows buildslaves, a returned VBox testslave, and more reliable ISO downloads. The VMware testslave is not back yet, but I'll be reinstalling this one as well. In June, we also plan to upgrade our best-performing server even more, using the donated 64GB of RAM and CPU upgrades that are cheaply available these days. This should decrease build times even more! Cheers, Colin

GSoC Mentor

by Muhammad abdul Rehman

Hello everyone, I am a Masters student and want to do the GSoC with this organization this summer. I have gone through the list and found some projects domain interesting but I couldn't research in the depth of the project due to resource and time constraint at the moment. I have some professional background in working with embedded software development (mostly C programming), networking stacks and an RTOS porting. Did some work in Linux development as well. I will be thankful if someone can guide me chose the best suitable project that is beneficial for myself and the organization at the same time. Currently, I have a look at following projects: Bluetooth Stack Integrating SMB into ReactOS Kernel mode test suite WebKit-based MSHTML implementation Support for the GPT Partitioning Scheme Taskbar Shell extensions If someone is interested in mentoring anyone of the above project, I will be happy to talk more on that and submit a timely proposal. Thanks a lot and best regards, -- M Abdul Rehman

Opening up #reactos-dev to the public

by Colin Finck

Hi all! As you all know, our #reactos-dev IRC channel has been a moderated IRC channel for decades, and only operators (devs) and voiced people can talk. While we always tried to keep discussions dev-related there, no topic has ever been enforced on #reactos. The result is that I see a notable number of developers only on #reactos-dev these days. This is a pretty bad situation! Emerging developers hardly have a way to interact with all existing devs on IRC. Often enough, legitimate questions from them remain unanswered on #reactos. Moreover, we don't maintain the list of voiced people thoroughly, so even some contributors have to ask for temporary voice on #reactos-dev. Keep in mind that we're currently in the GSoC phase where students shall submit their proposals and get in touch with the developers. How are they going to do this on IRC if #reactos-dev continues to be an exclusive club? Because of these reasons, I'm proposing to remove the moderation bit on #reactos-dev and let everybody talk there. Its development topic should be enforced though! As soon as people get too off-topic, they should be directed to #reactos and kicked if nothing else helps. Given that all devs are already operators on #reactos-dev, it's fully in their hands. Cheers, Colin

If someone requests something other than SID_SShellBrowser, we'll just return them a different object without any indication that something is wrong. Shouldn't we either pass guidService down or fail somehow if it's not asking for ShellBrowser?

New dev doubts/questions

by Pranay Pratyush

Hi there, I feel extremely enthusiastic about contributing to reactos through gsoc. I looked into the idea list for 2017 and "Audio Mixer" looks the most interesting to me. But I have absolutely no experience writing windows services, let alone kernel streaming. I have experience with linux internals and I have used Windows APIs in the past. I am really interested in this. How do I get a mental map of what all things I need to do to achieve this? What all stuff do I learn for this and how? Also suggest me if I should drop this entirely and conribute through coding something less "ambitious". -- *Pranay Pratyush,* 3rd year undergraduate , Computer Science and Engineering Department Indian Institute Of Technology, Kharagpur --

Legal advice concerning contribution to ReactOS

by tobias.k＠posteo.de

Hi, I've a question concerning legal restrictions. As mentioned on this page https://reactos.org/wiki/Subversion#Prerequisites I'm not allowed to contribute to ReactOS when I'm an employee of Microsoft or of any subsidiary of Microsoft. In the past, I worked for a German company which was a Certified Partner of Microsoft. As far as I know, it was not a subsidiary of Microsoft. It's not even listed here https://en.wikipedia.org/wiki/List_of_mergers_and_acquisitions_by_Microsoft (but I don't know if this list is complete). Since a Certified Partner is not automatically a MS subsidiary or equivalent to it in a sense (as I think), there shouldn't be a problem for me contributing to ReactOS. Is there anybody who can confirm that? Tobias

JIRA/FishEye upgrade on March 8

by Colin Finck

Hi all! Let me announce a definite date for our JIRA/FishEye upgrade: Wednesday, March 8, around 9:00 UTC Expect downtimes of several hours at https://code.reactos.org and https://jira.reactos.org around this time. I can say for sure that I will have enough time on this day and the following to deal with all possible incidents that could happen during the complex upgrade. This also allows me to get direct in-person feedback from all the devs attending CLT on the weekend after that :) The upgrade to JIRA 7.x is a major one, and Atlassian recommends everyone to have a look at the new features: https://confluence.atlassian.com/migration/jira-7/server_jira_product-chang… Best regards, Colin

YNT: New ideas added to GSoC Ideas list

by Can Tasan

Dear Ricardo, Firstly, Win16 application support doesn't interrupt our project. It strengthens us. On technical view, supporting them doesn't make any design change to NT architecture, apps won't be able to access hardware directly. Like any app, they'll obey the rules. Secondly, there are a number of reasons to support Win16: 1) Many people and corporations still use DOS and Win16 apps today, thus their system can't be upgraded easily. Most of the cases, DOSBOX will do the job but what if any problem occurs, or integration with system is needed? With Win16 support out of the box, people will get much more technical support and security updates. 2) Many apps released in 90s have 16 bit setups, even they are actually 32-bit. In this case, compatibility and usability of ReactOS greatly decreases. 3) Sometimes emulation may be not enough for special cases. 4) There are many games from 16 bit age which is still played today. Supporting them makes a bonus. In my opinion, this cases makes WoW16 support viable. Apologizes if I forget something and sending this twice, accidentally pressed the send button. Best regards, Can

Re: [ros-dev] New ideas added to GSoC Ideas list

by Can Tasan

I also have some ideas here, not fully sure about their feasibility. Tried to be wise as much as I can. -Continuing USB work that vardanm started. Yes, I know a developer is working on that. Another joining student would be great and speed up things. -Continuing TCP/IP stack work if noone is working on rewrite. -Working on DirectX support: bringing new features, fixing bugs, optimising, if possible fixing some driver issues... -Fixing driver unloading/fallback problem (CORE-8294) I think it's a hurdle on our hardware compatibility, but not sure its priority. -Would some kind of Win32 subsystem work be too hard? -Implementing some missing things in shell. -Implementing more user mode stuff, or is it enough for now? -Extending printing support. -Fixing current audio support, if our devs don't want to tinker with it. -Implementing WoW16 support. I suppose that'll draw attention. And as said before, proper application compatibility database. :) By the way, I'm too pleased to join and see you here all! With my best regards, Can Taşan

Definite Decision about ISO lifetimes at iso.reactos.org

by Colin Finck

Hi all! We used to remove any ISOs at https://iso.reactos.org that were older than 2 years. Then some devs wanted access for a little longer and we stopped deleting any. Now we recently ran out of space on that server... Even though we are about to double our storage capacity, I want a definite decision about the lifetime of ISOs at iso.reactos.org. Something that serves us well over the next few years. Otherwise, we will just run into the same problem again in the near future. My proposal =========== bootcd-dbg: 5 years bootcd-dbg-msvc: 5 years bootcd-rel: 0.5 years bootcdregtest: 1 week livecd-dbg: 0.5 years livecd-dbg-msvc: 0.5 years livecd-rel: 0.5 years Having the DBG Boot-CDs up for 5 years should cover all reasonable regression testing in my opinion. I'm not that much into testing as you though, so if any of these lifetimes are too short for you, please speak up now. Otherwise, I'm going to implement this by next Wednesday, March 22.

Regarding Smart Commits

by Colin Finck

Hi all! Some people have noticed that Smart Commits (#resolve, #comment, etc.) have stopped working after the JIRA/FishEye upgrade. This is due to the new per-user OAuth authentication between both systems, which means that every committer needs to authorize FishEye once to impersonate as your JIRA account. FishEye only tells you this and the URL to fix it after the first failed Smart Commit, but here it is: https://code.reactos.org/plugins/servlet/applinks/oauth/login-dance/authori… Click that, confirm and all subsequent Smart Commits should work. Make sure you are logged into JIRA and FishEye before. Cheers, Colin

Work on dxg.sys

by Sebastian Gąsiorek

Hi, Couple of days ago I have started dxg.sys functions implementation. There is some progress but it would be good to write tests for this api. Dxg mostly is just wrapper between driver and win32k, so win32k api tests should be enough. I saw some tests in rostests\dxtest\win32kdxtest but can't figure out how to enable them in build. Could some help me with this and add proper cmake files? :) Best regards, Sebastian

CLT, one seat left

by Daniel Reimer

After some strike related problems we lost one of our supporters @ Chemnitzer Linux Tage (https://chemnitzer.linux-tage.de/2017/de) SO if someone wants to join. Here we are, waiting for ya. Start is on THIS saturday and ending is THIS sunday evening. Yes, quite a bit early I ask here, but... sadly the problems showed up today. We might even have a hotel room left if our hotel does not cancel it that close to booking date. Otherwise we find a way, too. So, first come first served. Sell your soul/come to us ^^

Buildslave disk space problems fixed

by Colin Finck

Hi all! We have run out of space on our temporary universal Build and ISO machine HotelLux today. This is why TestCD creation has been failing. I'm currently moving files away from the main disk to a temporary storage. You should already be able to redo the failed builds. Within this month, Aleksey and me will move the ISO storage back to our actual storage server, upgraded with larger disks. This one should be sufficient for quite some time. Sorry for the inconveniences! Cheers, Colin

Status Meeting (February 2017)

by Aleksey Bragin

Hello, Let me invite you to the monthly status meeting taking place tomorrow, 23rd of February, 19:00 UTC. IRC service will only be started shortly before the meeting. Your participation passwords and server address will be emailed to you shortly before the meeting starts, and they are going to be different once again as they are not stored in any database. Hopefully it's not much of inconvenience. Alternatively we'll do it in #reactos-meeting on Freenode, depending on our admins mood. Please send agenda proposals to me before the meeting so we don't waste time trying to setup the agenda directly during the meeting. Regards, Aleksey Bragin

Office (Excel, Word...) 2010 on ReactOS

by Hermès BÉLUSCA-MAÏTO

Hello everyone, Today I was finally able to finish the installation of Office 2010 in ReactOS, using as a temporary measure the Wines NTLM layer that calls into the ntlm_auth utility of Samba. This was done while Samuel is completing his NTLM implementation. As this wine layer is here running on ReactOS, few modifications were needed, and I also needed to find a Windows build of Samba. Ive found one, by chance, at http://smithii.com/samba . Then, using ReactOS revision 73868 (or later), and using this version of Samba, the Office installation finishes (reminder: the problem was due to the fact the installer needed NTLM to communicate with the Office Software Platform Service, OSPPSVC.EXE). We are now able to use Excel, Word, on ReactOS, as shown in this picture: http://i.imgur.com/fLEwoVI.png There are now 2 main problems: - NTLM should be correctly implemented; - There are an awful lot of drawing problems with Office 2010 applications (similar to those of Office 2007 apps): for example, dragging the graph downwards shows his frame going upwards; there are many black regions that show up, etc...: It seems we have problems in coordinate frames. And other problems too. Also, we have some mouse capture problems: if you try to redimension the windows the normal way (bring mouse cursor on top of the border, left-click-maintained, move mouse, release left button), and then move the mouse inside the window, it continues to be redimensioned... As a result, I took ~=15 minutes to make this simple trivial picture above, almost all the time taken to fight against window dimensioning & the drawing problems. But anyways, enjoy ! This will be part of my next blog report. Cheers, Hermès

JIRA/FishEye upgrade this weekend

by Colin Finck

Hi all! Due to the current unstable situation with FishEye, which also badly affects JIRA, I will attempt an upgrade of both applications on a new server this weekend. As always I will do my best to keep the downtime low. But keep in mind that this involves migrating databases from one machine to another, so downtime may be longer than for a usual upgrade. In the end, you can expect/hope for a much better performing setup with all the new features that got added to JIRA and FishEye over time :) Cheers, Colin

Re: [ros-dev] Microsoft switched to Git

by Alex Ionescu

I too have no idea where this "history limit" comes into play. I work on and have repos spaning 50-100 developers working on dozens of thousands of branches over two dozen repos with almost 8 years of history. Some people rebase, but most people don't. It is extremely easy to have a clean history due to the fact we enforce the "[COMPONENT] Description" commit message (and can use a git hook to make sure it looks this way). It is then trivial to write a script that only looks for those commits. Heck you can even auto-squash/rebase anything that doesn't match. That being said, that type of "dirty history" only happens if you heavily work with branches. That's not how reactos developers work -- we don't open PRs and separate branches for every checkin. These ALL sound like manufactured problems or poor/strange use of git.

Re: [ros-dev] Microsoft switched to Git

Sure, I didn't count git add because you can do it with git commit -a. git status/log are the same as the svn equivalents. just like git diff/svn diff. I was mainly referring to regular workflow. In fact, I think outside of stash (which is an optional, but awesome, feature) fetch and rebase (which I refuse to learn), all commands map 1:1 with svn. That's why I don't get this whole "it takes way more commands/steps in git". git commit -a -m "[BOOTLIB] Fix yet another bug]" git push Done.

I've never used any other git command other than those (except git checkout). Oh, that's lie, I've also used "git branch", just like on svn, to create a branch. Sounds like you've never actually used git? I've never rebased in my life, and I don't know what other commands even exist. Best regards, Alex Ionescu
