System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce 920M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 416.81

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-05 16:36, hash: 699193713f
Worked: 2.79b

Short description of error
If not set "orient_matrix" value in operator bpy.ops.transform.rotate, object will be rotate in anoter side. This works for GLOBAL and LOCAL orientations.

For Example:

bpy.ops.transform.rotate(value=0.349066, orient_axis='Y', orient_type='GLOBAL', orient_matrix_type='GLOBAL', constraint_axis=(False, True, False)) must rotate global Y axis 20 degrees.
In fact: Rotate global Y axis -20 degrees.

or

bpy.ops.transform.rotate(value=0.349066, orient_axis='X', orient_type='LOCAL', orient_matrix_type='LOCAL', constraint_axis=(True, False, False)) must rotate local X axis 20 degrees.
In fact: Rotate local X axis -20 degrees.

Exact steps for others to reproduce the error

Create New File and select Default Cube
Open Python Console
Run: bpy.ops.transform.rotate(value=0.349066, orient_axis='Y', orient_type='GLOBAL', orient_matrix_type='GLOBAL', constraint_axis=(False, True, False)) or bpy.ops.transform.rotate(value=0.349066, orient_axis='X', orient_type='LOCAL', orient_matrix_type='LOCAL', constraint_axis=(True, False, False))
Check result cube's rotation

Confirmed.

@ideasman42 : just guessing: not sure why we are inverting spacemtx in initTransformOrientation here (if skipped for for the non-modal case, issue seems to be gone...)?

Also If you set the orientation type to VIEW and dont set the orient_matrix, it will use the global orientation.

This bug was gone in 2.90.1 but has now reappeared in 2.91 and is even worse as setting orient_matrix no longer prevents the bug. As far as I can tell there is now no way to get transform.rotate to output a none reversed rotation without inverting a value.

Since this is a bit of a new situation in 2.91, could you make a new report for this?
(you can also reference this report in the new one, but overall, this will make it easier to track progress, thx)

Done https://developer.blender.org/T83092
Now effects Mesh edit and pose mode as well. Ouch

Can not replicate the issue. Checked with 2.93 LTS and 3.0.0 (d1e1d6c491). Issue was there in 2.92 release.

Hi @lichtwerk , are you able to reproduce the problem with 2.93LTS?

Output:

2.92	2.93LTS

This was fixed by 92743cc895, so bug is not in 2.93 nor 3.0.
Will close as resolved (but of course feel free to comment again if issues persist)
