  1. Support Oracle Berkeley DB and lmdb

    Both Oracle Berkeley DB and lmdb fail on WSL as of build 18204. This is due to an issue with mmap described at https://github.com/Microsoft/WSL/issues/658 and https://github.com/Microsoft/WSL/issues/902

    Please fix the mmap issue so that lmdb and Oracle Berkeley DB, and projects relying on them, work in WSL.

    • Backup/Restore/Share/Snapshot a WSL installation

      Backup / Restore / Snapshot a WSL installation.

      For development puproses it would be very nice to ba able to backup a WSL installtion and to resore it on the same or another(!) PC.

      Provide a means of 'going back' (like a VMware snapshot) when a WSL installation became unstable, bloated, corrupt.

      BTW is there a way to have more than one Ubuntu installations at the same time?

      Best regards.

      • Add support for 32-bit ELF executables

        A lot of tools written for Linux can be downloaded as 64-bit, but there are still a few that only 32-bit downloads are available for. I've tried using virtual machines, but that tends to not be feasibly in some projects.

        • Support for sparse files in LxFS (flow type checker fails) WSL#1732

          This issue says it better than I can:

          https://github.com/Microsoft/WSL/issues/1732

          Real Linux:

          $ truncate -s 27927781376 foo
          $ ls -l foo
          -rw-r--r-- 1 ken ken 27927781376 Feb 27 21:00 foo
          $ du --block-size=1 foo
          0 foo

          WSL 15042:

          $ truncate -s 27927781376 foo
          $ ls -l foo
          -rw-r--r-- 1 ken ken 27927781376 Feb 27 21:00 foo

          • Add libusb support to WSL

            Since previous one(https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/16759696-add-usb-device-support) was marked "complete", this one more clearly states support for libusb as in any usb device raw, rather than just storage mounting and serial pass-through.
            My example need is Yubikey gpg-card.

            • Add support for FAT "Function not implemented"

              Add support for FAT drives mounted in windows to be accessible under WSL.

              Currently, you receive "Function not implemented"

              This would allow Google Drive to be accessible under WSL.

              • Recursive file case sensitivity?

                Can we get folder recursive case sensitivity? You've very recently added it with:
                fsutil.exe file SetCaseSensitiveInfo C:\folder\path enable
                what do we have to do to get full directory case sensitivity?

                It's really confusing as to why this isn't implemented yet when NTFS has supported it forever and windows 10 has no more kernel excuse...

                Is something like this necessary?

                [string] $PathRoot = 'folder here'

                [bool] $EnableCaseSensitivity = $true

                @(Get-ChildItem -Path $PathRoot -Recurse -Directory | Select-Object -ExpandProperty 'FullName') | ForEach-Object {
                cmd /c ('fsutil.exe file SetCaseSensitiveInfo "{0}" {1}' -f ($_,$(if($EnableCaseSensitivity){'enable'}else{'disable'})))
                }

                • Enable/Install WSL within a Docker Windows container

                  Hi everyone,

                  I am wanting to enable and install the Windows Subsystem for Linux (WSL) feature from within a Docker windowsservrecore container.
                  However, due to the fact that Docker containers are more like full-environment-processes than VMs,
                  and because WSL feature installation requires a 'system reboot'; this has proven troublesome.

                  I have seen solutions that other people have figured out for installing features that normally 'require reboot' in a Docker windows container:
                  - e.g. Active Directory support: https://blogs.msdn.microsoft.com/containerstuff/2017/01/30/create-a-container-with-active-directory-support/
                  - e.g. Server Media Foundation: https://www.impostorprogrammer.com/articles/docker/media_foundation_windows_containers.html

                  So I was wondering if anyone had any thoughts or has managed something similar for getting WSL…

                  • Add libgl support to WSL

                    There are many development tools unable to be ported to Windows due to their proprietary nature and others that though not proprietary have no interest in porting to Windows. For me specifically, it's being able to utilize dev tools such as VSCode, Sublime Text, Draft, Javalin, Bootsnap, OSQuery, and/or FSQL without downloading a third party X server that only does partial implementation. Libgl is specifically required to get GUI apps to run and doesn't currently exist. Please implement libgl and create an API for driver makers to use to enable use of these and other GUI dev tools.

                    • Combined Process List Between WSL and Windows

                      I'd love to see the process list that's available from CMD's "tasklist" added to WSL's "ps" command. I understand that'll take some process ID juggling, but I think it's doable. If I'm in a bash shell and I do a "ps auxww" I'd love to see *every* process running on the box, not just what's in WSL.

                      That would also allow me to kill them from within the bash shell vs doing it via cmd. Yes, I know I can "cmd /c tasklist" and "cmd /c taskkill" from bash. I'd rather see it done via the built in "ps" and…

                        • Add framebuffer support (/dev/fb0)

                          First of all, WSL is great! Thanks for this amazing feature!

                          Now, please support frame-buffer device implementation, we develop many C/C++ apps that draws its graphs directly by open fb like this:

                          int open_framebuffer(void)
                          {
                          const char *fbname;
                          int ret;

                          fbname = getenv("FB");
                          if (fbname == 0)
                          fbname = "/dev/fb0";

                          ret = open(fbname, O_RDWR);
                          if (ret == -1)
                          ret = open("/dev/fb/0", O_RDWR);

                          return ret;
                          }

                          WSL has no framebuffer device yet, so please bring us a complete fb0 device!

                          • WSL add ability to scroll up

                            In the WSL you should be able to scroll up and see your previous sessions commands/output (much like you can with cmd). Currently you only get what you can see on the screen, forcing you remember to pipe everything to less.

                            • To be able to open tabs would be great.

                              I am stuck using a MAC at work because the terminal is far superior. with Linux/MAC I can open multiple tabs in the terminal, with windows WSL I have to open a bunch of windows. Sometimes I will has 7 or 8 tabs open at once... Adding tabs to the command terminal would be an excellent upgrade. I work with a bunch of DevOps and TechOps people and the vast majority would rather be using windows, but because of the lack of features with the command box they are stuck using MAC's

                              • Acting on Windows 10 Network Adapters

                                I don't seem to be able to modify Windows network settings from inside the Ubuntu WSL shell.
                                Doing "ifconfig wlan0 off" doesn't turn the wifi off, neither other commands or softwares I tried.
                                Is there any way to turn off network adapters from inside the shell?

                                  One of the things that are in muscle-memory is
                                  - select text with mouse
                                  - change to other window
                                  - middle-button to paste

                                  Middle-button or Right-button is one thing, but I always forget to right-click to copy after selecting so I end up pasting something quite unintended .....

                                  Can we please have auto-copy-on-select when using QuickEdit? It's even quicker that way :-)

                                  Regards,
                                  Bent

                                  • Copied selection should include newlines instead of spaces

                                    When copying multiple lines, WSL doesn't detect newlines, and simply includes ~hundred spaces depending on the line length.

                                    Example: if I copy the output of `echo -e "hi\nhi\nhi"`, WSL will actually capture "hi hi hi" instead of "hi
                                    hi
                                    hi"

                                    • Add suppor to Bluetooth on WSL

                                      Exposing bluetooth to the WSL is necessary to develop IoT without having ot fire up a Viertual Machine.

                                        • Allow WSL root folder location to be in a separate EXT4 partition recognized by windows

                                          The idea is basically allowing the user to actually play with the files in a GUI environment with all the added perks of an explorer window.
