Great info, I added a sort to see which packages might be taking up more time:
qlist -I | xargs qlop -t |sort -t" " -rnk2 |

Thanks for pointing out my mistake krinn, there was really an error. Since the format of the output from this command is d:h:m:s hours should be always less than 24 (remainder from 86400 seconds division), like minutes (remainder from 3600 seconds division) and seconds (remainder from 60 seconds division) are less than 60. $2 / 3600 should be ($2 % 86400) / 3600
I updated again the first post.

I think it would be suitable for qlop from q applets.
I can open a bug report asking for this feature if people want to.

Hi there,
have you tried genlop?
| Code: |
$ emerge --pretend --emptytree @world | genlop --pretend
[...]
Estimated update time: 5 hours, 39 minutes.

Your tip worked, but it has some caveats:
1) It took a big while to complete (maybe 1 minute?);
2) The output is very verbose because of emerge (using --quiet hasn't effect to minimize this);
3) Emerge will look into new packages to satisfy dependencies, not only the already installed, maybe increasing the time in the answer.
Other than these problems, the final answer was Estimated update time: 1 day, 2 hours, 4 minutes., which is pretty close to my script answer of 25h:1m:32s

qlop seems unreliable for some cases. My script (see my signature) provides an estimated time | Code: | quietemerge -pe1 @world
...
Total ETA: 1d 16h 24m 10s |
The command in the main post provides an estimated time of over 10 days | Code: | ~» qlist -I | xargs qlop -t | awk '{secs += $2} END { printf("%dh:%dm:%ds\n", secs / 3600, (secs % 3600) / 60, secs % 60); }'
290h:22m:38s |
It seems that some of the estimates made by qlop are incorrect: | Code: | » qlop -v -g -H qtcurve
qtcurve-1.8.17-r1: Sat Mar 22 11:19:38 2014: 1 minute, 19 seconds
qtcurve-1.8.17-r1: Thu Apr 24 04:27:08 2014: 39 seconds
qtcurve-1.8.17-r1: Sun Oct 19 22:44:02 2014: 51 seconds
qtcurve-1.8.18-r1: Sat Feb 20 19:07:04 2016: 2 minutes, 16 seconds
qtcurve-1.8.18-r1: Sun May 8 14:10:10 2016: 2 minutes, 8 seconds
qtcurve-1.8.18-r1: Sun May 7 22:41:07 2017: 104 days, 13 hours, 34 minutes, 53 seconds
qtcurve-1.9.0_rc1-r1: Sun Oct 1 16:37:44 2017: 2 minutes, 20 seconds
qtcurve-1.9.0_rc1-r1: Sat Nov 11 17:14:05 2017: 1 minute, 32 seconds
qtcurve-1.9.0_rc1-r1: Mon Jul 2 19:38:20 2018: 1 minute, 7 seconds
qtcurve-1.9.0_rc1-r2: Sun Jul 15 19:13:07 2018: 1 minute, 50 seconds
qtcurve-1.9.0: Sun Oct 21 20:23:40 2018: 2 minutes, 20 seconds
qtcurve: 11 times |
On the other hand, the estimates provided by the internal computations in the quietemerge script gives the following (in reverse order to above): | Code: | ~ » mygenlop qtcurve
* Printing the times in reverse order (recent emerge appears first)
Run no. Time Taken
1 2m 20s
2 1m 50s
3 1m 7s
4 1m 32s
5 2m 20s
6 1m 2s
7 2m 8s
8 2m 16s
9 51s
10 39s
11 1m 19s
* Average time taken over 11 runs: 1m 34s |

I don't know if some else has already mentioned this, but the estimation the command gives is almost always larger than the actual world compile time, unless one disallows parallel merging of packages (emerge --jobs <n>).

I was thinking the same thing. Though, you may be able to get a sensible estimate by dividing the result by the number of cores you have (assuming they are all the same spec). Won't be precise, but would probably be close enough to be informative as a real world estimate. |

Any bigger package that can run make -j<N> effectively at compile phase would normally limit emerge --jobs mto just one.
For example I have --jobs 8 --load-average 10.00 on my EMERGE_DEFAULT_OPTS.
So maximum of 8 concurrent package installs/compiles, but only is load average is under 10.00.
So sometimes for example Firefox and libreoffice both get to be compiled at the same time, effectively lenghtening the compile time of both on my 8-core CPU (would result around load average of 16). In this case compile times recorded for these packages are 2x at worst.
On the other hand some small packages that really can't fully utilize make -j8 (on my system), are almost always being run at 1x speed, but those can be "emerged" parallel (at most of 8 packages being compiled/installed at the same time).
In this case it's the opposite to the previous one. Since on average all those smaller packages are "emerged" in "time * 1/8". But the method counting the world compile time gives each 1x time instead of 1/8.
So you can't just divide the time by the cores on your system... unfortunately.

For what is worth, with portage-utils-0.80_pre*:
| Code: |
% qlop --summary
...
sync: 1′56″ average for 1 sync

The other issue when genlop is you have to still have all the logs for the last build you did of every single package that's installed or the time is off. It must read the log files to get the time. Because it will warn you if there are log files missing |

I run several systems that are fully ~amd64 keyworded. Have never had what I'd call serious problems. Sometimes something will fail or an issue will arise so I have to mask something. But it doesnt happen too often. My package.mask is maybe 15 lines. Of those half of them were by choice. And I could probably get rid of half of the rest as they are older packages. |

Do you have color forced on? Like in emerge_default_opts or something? I know having --color=y will totally confuse genlop -p |

Worked for me.

These are the pretended packages: (this may take a while; wait...)

It did indeed take a while.

I've been on the ~ -side. The problem isn't so much the "unstabliness" of the packages, but rather the update frequency. And of course it's nice to have the feeling of stable system on a home server.

I can certainly agree with that. I do run stable on my media server simply because that box is lower specs and would take forever to update if it was on ~arch. Still runs an old amd phenom 955.
Although unstable is currently a little "hairy" too. The switch fro. Cblas blas and lapack reference packages to a single lapack package that includes all three blas cblas and lapack reference libraries has tons of stuff failing with undefined references to various cblas_* (cant remember the exact error) functions or whatever. That revdep-rebuild wont catch. Something just wasnt rebuilt right I just don't know what yet. I'll prob just end up emerge -e @world to fix it if I cant figure out exactly what package it is. So it does get crazy sometimes too but I expected this since moving to that single package and allowing it to be selected and picked up by ld.so was a very radical change. |
