[Week 7] Porting Microsoft's CoreCLR, CoreFX, and PowerShell to FreeBSD

[Mateus Rodrigues de Morais]

During this past week I investigated the misbehaviors I encountered in PowerShell running on FreeBSD. I opened an issue [1] in the PowerShell GitHub repository, fixed all libpsl-native tests that were failing and submitted a PR [2] and went over some of the CoreFX tests that were failing.

It turns out it was a problem in the getmntinfo() function inside a CoreFX native function that was supposed to return all mount points in the system but wasn’t returning any. I fixed the code and, as a result, two out of three identified misbehaviors in PowerShell were fixed – now I’m able to navigate back and forth in the file system and the command prompt correctly shows the current working directory – and some of the CoreFX tests started passing. The PR for this fix should be up soon, the code is in my CoreFX fork [3].

The last misbehavior identified in PowerShell so far, which is the repeated characters being shown, is still under investigation.
