Collaborative maintenance | Emilio Pozuelo Monfort's blog

The Debian Python Modules Team is discussing which DVCS to switch to from SVN. Ondrej Certik asked how to generate a list of commiters to the team’s repository, so I looked at it and got this:

emilio@saturno:~/deb/python-modules$ svn log | egrep "^r[0-9]+ " | cut -f2 -d'|' | sed 's/-guest//' | sort | uniq -c | sort -n -r 865 piotr 609 morph 598 kov 532 bzed 388 pox 302 arnau 253 certik 216 shlomme 212 malex 175 hertzog 140 nslater 130 kobold 123 nijel 121 kitterma 106 bernat 99 kibi 87 varun 83 stratus 81 nobse 81 netzwurm 78 azatoth 76 mca 73 dottedmag 70 jluebbe 68 zack 68 cgalisteo 61 speijnik 61 odd_bloke 60 rganesan 55 kumanna 52 werner 50 haas 48 mejo 45 ucko 43 pabs 42 stew 42 luciano 41 mithrandi 40 wardi 36 gudjon 35 jandd 34 smcv 34 brettp 32 jenner 31 davidvilla 31 aurel32 30 rousseau 30 mtaylor 28 thomasbl 26 lool 25 gaspa 25 ffm 24 adn 22 jmalonzo 21 santiago 21 appaji 18 goedson 17 toadstool 17 sto 17 awen 16 mlizaur 16 akumar 15 nacho 14 smr 14 hanska 13 tviehmann 13 norsetto 13 mbaldessari 12 stone 12 sharky 11 rainct 11 fabrizio 10 lash 9 rodrigogc 9 pcc 9 miriam 9 madduck 9 ftlerror 8 pere 8 crschmidt 7 ncommander 7 myon 7 abuss 6 jwilk 6 bdrung 6 atehwa 5 kcoyner 5 catlee 5 andyp 4 vt 4 ross 4 osrevolution 4 lamby 4 baby 3 sez 3 joss 3 geole 2 rustybear 2 edmonds 2 astraw 2 ana 1 twerner 1 tincho 1 pochu 1 danderson

As it’s likely that the Python Applications Packaging Team will switch too to the same DVCS at the same time, here are the numbers for its repo:
emilio@saturno:~/deb/python-apps$ svn log | egrep "^r[0-9]+ " | cut -f2 -d'|' | sed 's/-guest//' | sort | uniq -c | sort -n -r 401 nijel 288 piotr 235 gothicx 159 pochu 76 nslater 69 kumanna 68 rainct 66 gilir 63 certik 52 vdanjean 52 bzed 46 dottedmag 41 stani 39 varun 37 kitterma 36 morph 35 odd_bloke 29 pcc 29 gudjon 28 appaji 25 thomasbl 24 arnau 20 sc 20 andyp 18 jalet 15 gerardo 14 eike 14 ana 13 dfiloni 11 tklauser 10 ryanakca 10 nxvl 10 akumar 8 sez 8 baby 6 catlee 4 osrevolution 4 cody-somerville 2 mithrandi 2 cjsmo 1 nenolod 1 ffm

Here I’m the 4th most committer 😀

And while I was on it, I thought I could do the same for the GNOME and GStreamer teams:

emilio@saturno:~/deb/pkg-gnome$ svn log | egrep "^r[0-9]+ " | cut -f2 -d'|' | sed 's/-guest//' | sort | uniq -c | sort -n -r 5357 lool 2701 joss 1633 slomo 1164 kov 825 seb128 622 jordi 621 jdassen 574 manphiz 335 sjoerd 298 mlang 296 netsnipe 291 grm 255 ross 236 ari 203 pochu 198 ondrej 190 he 180 kilian 176 alanbach 170 ftlerror 148 nobse 112 marco 87 jak 84 samm 78 rfrancoise 75 oysteigi 73 jsogo 65 svena 65 otavio 55 duck 54 jcurbo 53 zorglub 53 rtp 49 wasabi 49 giskard 42 tagoh 42 kartikm 40 gpastore 34 brad 32 robtaylor 31 xaiki 30 stratus 30 daf 26 johannes 24 sander-m 21 kk 19 bubulle 16 arnau 15 dodji 12 mbanck 11 ruoso 11 fpeters 11 dedu 11 christine 10 cpm 7 ember 7 drew 7 debotux 6 tico 6 emil 6 bradsmith 5 robster 5 carlosliu 4 rotty 4 diegoe 3 biebl 2 thibaut 2 ejad 1 naoliv 1 huats 1 gilir

Conclusions:
– Why do I have the full python-modules and pkg-gstreamer trees, if I have just one commit to DPMT, and don’t even have commit access to the GStreamer team?
– If you don’t want to seem like you have done less commits than you have actually done, don’t change your alioth name when you become a DD 😉 (hint: pox-guest and piotr in python-modules are the same person)
– If the switch to a new VCS was based on a vote where you have one vote per commit, the top 3 commiters in pkg-gnome could win the vote if they chosed the same! For python-apps it’s the 4 top commiters, and the 7 ones for python-modules. pkg-gstreamer is a bit special 🙂

The useless use of … awards teach you that awk can basicly do everything except win the girl. Here is a much more optimized version of your one-liner that has 5 less pipes! Out of curiosity, can you run the awk-ified version of the command on your repo? How long does it take? WP will likely bork the formatting so you might need to fix the ‘ and “.

svn log scripts/ | awk ‘/^r[0-9]+ /{counts[tolower($3)]++} END {for (name in counts) { printf “%7d %s\n”, counts[name], name; }}’

Example:
jeff@omniscience:~/svn/systems/scripts$ svn log | egrep “^r[0-9]+ ” | cut -f2 -d’|’ | sed ‘s/-guest//’ | sort | uniq -c | sort -n -r

Jeff,

Thanks for your suggestion. Your command isn’t the same though. I’m removing “-guest” from the commiters, because there’s people who have made commits from two different accounts (e.g. morph and morph-guest), and I want to count them all in ‘morph’. Also, your command doesn’t print the commiters sorted, so you’d need to pipe it to “sort -n -r” to be the same.

And here you have the time:

emilio@saturno:~/deb/python-apps$ time svn log | awk ‘/^r[0-9]+ /{counts[tolower($3)]++} END {for (name in counts) { printf “%7d %s\n”, counts[name], name; }}’
[snip]
real 0m8.648s
user 0m0.112s
sys 0m0.044s

emilio@saturno:~/deb/python-apps$ time svn log | egrep “^r[0-9]+ ” | cut -f2 -d’|’ | sed ‘s/-guest//’ | sort | uniq -c | sort -n -r
[snip]
real 0m8.110s
user 0m0.132s
sys 0m0.028s

but repeating it the time is quite variable. I blame svn 😀
