For those still playing with this, some notes:
Taking numpy, for example:
| Code: |
$ qlop -t numpy

Note that the times vary (on the same machine) quite a bit because different amounts of parallelization are needed to get a working build (numpy is very sensitive to this). Also note that some unmerge times are included, because occasionally I had to unmerge numpy to make portage happy, and then merge it back in "carefully". (numpy is also very touchy like this.)
The '-t' option to qlop reports ALL emerge and unmerge times for a package. This is why some folks are getting huge numbers. Also note that the times are listed in field 4, not field 2. On my system, the OP script returns:
| Code: |
$ qlist -I | xargs qlop -t | awk '{secs += $2} END { printf("%dh:%dm:%ds\n", secs / 3600, (secs % 3600) / 60, secs % 60); }'
0h:0m:0s
|
If I change the awk field to 4:
| Code: |
$ qlist -I | xargs qlop -t | awk '{secs += $4} END { printf("%dh:%dm:%ds\n", secs / 3600, (secs % 3600) / 60, secs % 60); }'
211h:59m:59s
|
That explains why some folks are getting no times, while others are getting outrageous numbers. This is with qlop from app-portage/portage-utils-0.80.
With that version, the '-a' option for qlop reports an average:
| Code: |
$ qlop -a numpy
dev-python/numpy: 3′10″ average for 41 merges
dev-python/numpy: 4s average for 3 unmerges
|
Note that the time is now output in field two. There still two entries for emerges and unmerges, but the unmerges tend to be fast and don't effect the overall results too much. The average build time is quicker than my current build times, but not bad as a wag. Numpy is a worst-case package; most package build times don't show this much variation.
Using '-a' instead of '-t' and reverting back to field 2, the script produces:
| Code: |
$ qlist -I | xargs qlop -a | awk '{secs += $2} END { printf("%dh:%dm:%ds\n", secs / 3600, (secs % 3600) / 60, secs % 60); }'
15h:52m:43s
|
This estimate much more closely matches the average world build time that I see. Double that for the time spent resolving various build failures and filing the appropriate bug reports and patches. |

I know this is an old post but I figured I would show you guys/gals what I got for numbers too 
| Code: | | $ qlist -I | xargs qlop -t | cut -f4 -d" " | awk '{s+=$1} END {print "secs="s}' > /tmp/btime && eval $(cat /tmp/btime) && printf '%dh:%dm:%ds\n' $(($secs/3600)) $(($secs%3600/60)) $(($secs%60)) && rm /tmp/btime |
43h:26m:45s
| Code: | | $ qlist -I | xargs qlop -a | awk '{secs += $2} END { printf("%dh:%dm:%ds\n", secs / 3600, (secs % 3600) / 60, secs % 60); }' |

I realized that the number shown by this code is much too low (only ~20 hours).
Indeed:
| Code: | $ qlop -t gcc | cut -f4 -d" "
5:21:17
8:14:55
34s
$ qlop -t gcc | cut -f4 -d" "| awk '{s+=$1} END {print "secs="s}
secs=47 |
WTF? Aha:
| Code: | qlop -t gcc | cut -f4 -d" "| awk '{s+=$1;print s}'
5
13
47 |
The largest unit (typically hours or minutes) is just counted as a second and the rest discarded.
A fix is to pass the "-M" option to qlop -t:
| Code: | $ qlist -I | xargs qlop -tM | cut -f4 -d" " | awk '{s+=$1} END {print "secs="s}' > /tmp/btime && eval $(cat /tmp/btime) && printf '%dh:%dm:%ds\n' $(($secs/3600)) $(($secs%3600/60)) $(($secs%60)) && rm /tmp/btime

This looks more realistic. |

This show Compile Time with 'emerge -e @world
| Code: | | qlist -I | xargs qlop -a | awk '{secs += $2} END { printf("%dh:%dm:%ds\n", secs / 1800, (secs % 1800) / 60, secs % 60); }' |
Result: 19h:11m:28s
This show the amount of packages
| Code: | | find /var/db/pkg/ -mindepth 2 -maxdepth 2 -printf "%P\n" | wc -l |
Result: 1631
Regargs

My Gentoo VM running on a usb ssd attached to a new MacBook Pro.
I found this thread while I was looking about for a way to use qlop to predict update times like I used to do with genlop, "emerge -p command | genlop -p".
Any suggestions?
Thanks |

Slightly out of topic, but | list of packages which consumed the most time to build: | | qlop -mtM | awk '(pkg[$3] < $4) {pkg[$3] = $4} END {for (i in pkg) print i,pkg[i]}' | sort -nk 2 |
Takes the longest build for each package and sorts by time.
You can give -v to qlop to list all the versions of each package.
With | Code: | | qlist -Iv | xargs qlop -mtM |
...one could easily roughly estimate world compile time.
Maybe I should wrap up this in awk or in sh... Oh well...

| most time consuming builds ever plus total time compiling combined: | | qlop -mtM | sort -nk 4 | awk 'function hms(s) {h=int(s/3600); s=$4%3600; m=int(s/60); s=s%60; return h "h " m "m " s "s"} {total+=$4; print $3,hms($4)} END {print "Total: " hms(total)}' |
And adding qlist -Iv | xargs in front of that "oneliner" will limit to currently installed packages, with the possible caveat of including every build of the same package which version matches the installed one.
Curious ones can add pass -v for qlop to see what versions it really lists.
