Portage 2.0.51-r2 fails when a file named "tee" is in the directory emerge is run.

Upgrade portage to latest (2.0.51-r2) 2. Create a file in the working directory named "tee" (touch tee) 3.

I got the same error on my box. Please note that it not just fails, but tries to execute the file with root-permissions. I think this bug is also a security-issue. PS: Shouldn't the "Hardware"-field of this bug be changed from x86 to all?
Do either of you have PATH="." ?
No, '.' is not in PATH.
With portage-2.0.51.22-r2 I have to "chmod +x tee" in order to reproduce this error. There must be a subtle bug in portage_exec.find_binary().
Created attachment 64810 [details, diff] portage-2.0.51.22-spawn-path_lookup.patch This patch adds a test to see if myc is an absolute path or not. The problem is in this section at the beginning of portage_exec.spawn() where it can skip the path lookup if there is an executable file with the same name in the current directory. if not os.access(myc, os.X_OK): if not path_lookup: return None myc = find_binary(myc) if myc == None: return None
Fixed in 2.0.53
