Robert Guetzkow (rjg) added a comment to D4597: Better state indication for muted nodes.

Deactivating buttons makes sense. I'll have to check how to identify nodes that don't allow muting. I have an exam next Tuesday, so the update may have to wait for a bit. Perhaps we have a consensus on how the improvement should look like till then.

Currently the checkbox icon is displayed at all time, which may be distracting. Should it only be display when the node gets selected?

Robert Guetzkow (rjg) added a comment to T61412: Blender file explorer hard deletes data.

@Brecht Van Lommel (brecht) You're right I was oversimplifying. What I meant was if $XDG_DATA_HOME is set we know where to move the files to (+handle metadata for restoring). The bigger challenge may be that some distributions don't follow the spec and $XDG_DATA_HOME isn't set. For instance on my Ubuntu VMs 16.04 and 18.04 both don't have $XDG_DATA_HOME set. Your linked code from Electron probably already solves this by using the cli tools, which will default to gio trash for Ubuntu with Gnome as far as I can tell.

Robert Guetzkow (rjg) added a comment to T61412: Blender file explorer hard deletes data.

@William Reynish (billreynish) I guess this should be addressed for Linux and MacOS as well. Currently remove() and rmdir() are used for Linux and MacOS which are equally destructive.

Robert Guetzkow (rjg) added a comment to T61412: Blender file explorer hard deletes data.

@Kris (Metricity) I agree, the separate function makes sense. It's a good idea to have this functionality for Linux and MacOS, too. I'm not sure if Linux has a unified way of handling the trash directory. If Linux and MacOS have the path set in an environment variable it should be a simple mv operation.

Robert Guetzkow (rjg) updated the diff for D4585: Windows move files to recycling bin when deleted in file explorer.

Robert Guetzkow (rjg) updated the diff for D4585: Windows move files to recycling bin when deleted in file explorer.
  • Only use backward compatible FOF_* flags
  • Make progress silent, but show system dialogs when an error occurs, especially when a file would be permanently deleted because it can't be moved to the bin
  • Removed legacy interface, since code should work for Windows Vista and newer versions

Robert Guetzkow (rjg) added a comment to D4585: Windows move files to recycling bin when deleted in file explorer.

@LazyDodo (LazyDodo) That's what I thought. I wish they would properly document their API and give reason as to why certain recommendation are made (or even whether that is mandatory or a recommendation). I'll do some tests with the backwards compatible flags and if some others should be included as well, like FOF_WANTNUKEWARNING. It would be great if someone could test this on Vista, just in case something behaves differently.

Robert Guetzkow (rjg) added a comment to D4585: Windows move files to recycling bin when deleted in file explorer.

I've tested multiple subsequent file deletions and there was no problem, even with how CoUninitialize() is currently used. Not sure how sound this solution is, but it's working in my test environment.

Mon, Mar 25, 5:20 PM · Platform: Windows
Robert Guetzkow (rjg) added a comment to D4585: Windows move files to recycling bin when deleted in file explorer.

The COM handling seems to be a bit difficult with the CoInitializeEx() CoUninitialize(). As per the documentation I'm not exactly sure what they do on CoUnitialize that requires it to be called before closing the application (and not sooner). I'm not sure how we could satisfy this besides moving them to Blender's startup/exit code. Perhaps using the old interface is the better solution for now, if that causes too much of an headache.

Robert Guetzkow (rjg) added a comment to T61412: Blender file explorer hard deletes data.

Perhaps we could do the following: We could implement BLI_delete_recycle, but use #ifdef WIN32 in file_delete_exec to call this function only if it's Windows. This would avoid confusion about the Linux function call, which in your patch is just a wrapper for the regular BLI_delete.

Mon, Mar 25, 11:31 AM · BF Blender
Robert Guetzkow (rjg) added a comment to T61412: Blender file explorer hard deletes data.

@Kris (Metricity) I'm not sure that the BLI_delete_recycle is a good idea, since the Linux version does not recycle. Is there any particular reason why you'd want a new function?

Robert Guetzkow (rjg) added a comment to T61412: Blender file explorer hard deletes data.

@Kris (Metricity) I have implemented a first version that works, but I'll have to do more testing. The API's documentation is C++ only, which made it a bit difficult. I'm also not sure whether the choice between COINIT_APARTMENTTHREADED vs COINIT_MULTITHREADED makes a big difference. For simplicity I chose COINIT_APARTMENTTHREADED which is what the official examples use and by the [[ URL | https://docs.microsoft.com/de-de/windows/desktop/api/objbase/ne-objbase-tagcoinit ]] won't cause us any headaches with concurrency.

Robert Guetzkow (rjg) added a comment to T61412: Blender file explorer hard deletes data.

Looks like Windows made this one a bit more difficult. The FOFX_RECYCLEONDELETE was introduced for Windows 8, so I'm not sure how that functionality could be achieved on Vista using the new API. Perhaps we should use SHFileOperation for Vista and IFileOperation for newer versions?

Sun, Mar 24, 12:15 PM · BF Blender
Robert Guetzkow (rjg) updated subscribers of T61412: Blender file explorer hard deletes data.

@Kris (Metricity) SHFileOperation is the legacy API which doesn't support paths longer than 255 characters. If XP support is required we could use the VersionHelper to determine the OS version running an use IFileOperation if it's Vista or later. Otherwise I'd go with IFileOperation , because that is the the current API.

It seems you have some trouble with the process so let me try to explain it to you. The reason this is done with git even for two lines of code is to have a consistent and predictable end result when you've got several people working on the project.

@Bastien Montagne (mont29) thanks for taking care of this. I would suggest using a venv for building the docs though, that makes it far easier to have the same versions as the main docs and perform upgrades as needed.

The sphinx build shouldn't be a problem, everything down to the font-face definition in the css is correct. I think it's either a weird bug on @Jean Da Costa (jeacom256)'s system or the font file has some obscure error. The easiest way is to replace the Lato .woff2 files with a current version.

Robert Guetzkow (rjg) added a comment to T52258: bpy.ops.render.render('INVOKE_DEFAULT') returns 'CANCELLED' during UI interaction.

Yes that is what I was doing already. ‘EXEC_DEFAULT’ is used when no arguments are given. So the solution is to have no responsive/interactive UI and no preview.
I will take a look at the code. Perhaps this can be changed in future versions. It is very counter intuitive that the callback claims everything is done, but it isn't.

What you described as root issue was pretty much what I imagined. Unfortunately the re-try idea doesn't work well, once it has returned 'CANCELLED' it's pretty much guaranteed to fail at subsequent attempts.
