Bug 746902 – sys-apps/portage: option to show starting datetime in emerge output

• Product: Portage Development
• Status: UNCONFIRMED ---

[Description Erik Quaeghebeur 2020-10-06 10:26:38 UTC]

I would be convenient to have an option for emerge that makes it show the starting datetime of performed and current actions. Because this datetime info is available to emerge directly, it would be a light but convenient alternative to commands like qlop -t and genlop -c that need to be run in a separate shell.

For an illustration of what the output could look like, see the forum post <https://forums.gentoo.org/viewtopic-p-8509777.html>.

Reproducible: Always

I use the following patch.
--------------------------------

$ cat /etc/portage/patches/sys-apps/portage/timestamp.patch
diff --git a/lib/_emerge/JobStatusDisplay.py b/lib/_emerge/JobStatusDisplay.py
index 33e9551..33bb983 100644
--- a/lib/_emerge/JobStatusDisplay.py
+++ b/lib/_emerge/JobStatusDisplay.py
@@ -127,7 +127,7 @@ class JobStatusDisplay:
         return True
 
     def _format_msg(self, msg):
-        return f">>> {msg}"
+        return f">>> {time.strftime('%H:%M:%S',time.localtime())} {msg}"
 
     def _erase(self):
         self._write(self._term_codes["carriage_return"] + self._term_codes["clr_eol"])

--------------------------------
Then running emerge with the -q option I get output as follows :
