gentoo-perl / genlop Goto Github PK

Often, the merge time of some packages differs massively between versions. For example, on one of my machines, it took 9 minutes and 30 seconds to merge llvm-3 and 32 minutes to merge llvm-14. I think it would be useful to compute the merge time of packages using the last logged merge time as an estimate, rather than averaging all logged merge times. Possibly, one could have a flag to switch between the two behaviours.

Beside the ETA for the current package it would be helpful to also display a percentage or progress bar.

Please add the following powerful feature in genlop -c:
Beside the single ETA for the current package please add the ETA for all the pending packages.

As one one of the core features of genlop is the ETA calculation based on the emerge.log, another interesting calculation would be the total ETA for all the pending packages, which could also be easily possible.
However I guess that the calculation only based on emerge.log could be quite expensive and running a watch -n1 -cd genlop -c for some 50+ pending packages even more. Therefore a database replacing emerge.log could be required for such things.

Additionally I'm rotating and compressing my logs:

# cat /etc/logrotate.d/emerge
/var/log/emerge.log {
    create 660 portage portage
    rotate 2
    size 2M
    maxage 220
    nodateext
    compresscmd /bin/bzip2
    uncompresscmd /bin/bunzip2
    compressext .bz2
}

# type genlop
genlop is a function
genlop () 
{ 
    local opts args;
    for args in "$@";
    do
        opts+=("$args");
    done;
    for logfile in /var/log/emerge.log*;
    do
        if [[ -r "$logfile" ]]; then
            opts+=(-f "$logfile");
        fi;
    done;
    command genlop "${opts[@]}"
}

First:

$ genlop -c

 Currently merging 1 out of 1

 * sys-boot/grub-2.02_beta2-r3 

       current merge time: 7 minutes and 44 seconds.
       ETA: 1 minute and 23 seconds.

 Currently merging 473 out of 485

 * sys-devel/gcc-4.8.4 

       current merge time: 1 hour, 53 minutes and 5 seconds.
       ETA: any time now.

A little bit later:

$ genlop -c

 Currently merging 473 out of 485

 * sys-devel/gcc-4.8.4 

       current merge time: 1 hour, 56 minutes and 27 seconds.
       ETA: 1 hour, 36 minutes and 33 seconds.

 Currently merging 1 out of 1

 * sys-boot/grub-2.02_beta2-r3 

       current merge time: 11 minutes and 11 seconds.
       ETA: 1 hour, 39 minutes and 53 seconds.

If the project was adapted to gettext, I would take up Russian translation of it.

Instead of using watch -n1 -cd genlop -c it could be interesting to add a --monitor mode doing the same thing.
I guess that genlop -c always needs to parse the emerge.log, being an expensive call every 1s using watch.
Adding a --monitor mode could improve the calculation by only parsing once in a while.

This would make genlop be a real emerge monitor, adding ETA and progress calculations that emerge itself doesn't provide.
