To my market zero seconds

Code:
elover # qlist -I | xargs qlop -t | awk '{secs += $2} END { printf("%dh:%dm:%ds\n", secs / 3600, (secs % 3600) / 60, secs % 60); }'

For those still playing with this, some notes:

Taking numpy, for example:
Code:

$ qlop -t numpy
2012-03-12T17:16:12 >>> dev-python/numpy: 2′56″
2012-06-02T12:34:59 >>> dev-python/numpy: 2′59″
2012-12-07T10:41:48 >>> dev-python/numpy: 3′00″
2013-02-27T08:25:16 >>> dev-python/numpy: 2′17″
2013-05-24T09:00:28 >>> dev-python/numpy: 2′45″

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.
