* Why do some commits not appear in "git log"?

I'm having a problem understanding why "git log file" does not show some of the commits where file is changed. Consider the following commit history: > git log --pretty=oneline --abbrev-commit | head -20 e86d3b1 Merge remote-tracking branch 'git-svn' into MultiDataPath 05e7103 Made the system convert DP geometric info to MultiDP info and load it at machine start. 2de7375 Fixed compilation under Linux. b520873 Error handling!! 73110bd New Group manager for multi data processor dce3ae9 Merge branch 'MultiDataPath' of ssh://swteam/home/machine/git/SolarJet into MultiDataPath 25dff3c Merge branch 'MultiDataPath' of ssh://swteam/home/machine/git/SolarJet into MultiDataPath 247f418 Rewrite of the Finger heightmap nozzle selection algorithm for better load balancing. 026fec8 Stop all the jobs on async stop or on exception Choice nozzles using max nozzles number 84a60b7 avoid CarouselSimulationParams c40df74 git-svn-id: svn://swteam/SolarJet/trunk@4684 d8e1dcc2-e5e0-4eb0-83da-8cedbf775ddd : Now let's limit this to the history of a single file: > git log --pretty=oneline --abbrev-commit Apps/SolarJet/Project/qt/SysScripts/init.py | head 84a60b7 avoid CarouselSimulationParams c40df74 git-svn-id: svn://swteam/SolarJet/trunk@4684 d8e1dcc2-e5e0-4eb0-83da-8cedbf775ddd : As can be see above there were lots of commits omitted now. E.g. 05e7103 (the second commit above). But if I list the changes in 05e7103 I then get: > git show 05e7103 --name-only | grep init.py Apps/SolarJet/Project/qt/SysScripts/init.py Running without --name-only show that there is a substantial change in init.py So why does this commit not show up in in "git log file"? One interesting observation is that the only commits that appear in the "git log file" command are the commits that were imported from svn. All other commits are filtered out. So is this a bug, or am I doing something wrong? Thanks in advance! Dov ^ permalink raw reply [flat|nested] 5+ messages in thread

Also, rather than `head -20', you can limit the output directly with `-20': git log --pretty=oneline --abbrev-commit --full-history -20 It's hard to know what's going on in your particular example; perhaps give us the output of `git log' when using the `--graph' option. ^ permalink raw reply [flat|nested] 5+ messages in thread

Finally, a few more questions. Is it possible to make gitk use the --full-history option when running 'gitk file'? Is there any configuration flag that always turns on "full history"? Thanks!

Indeed these "substantial changes" by mistake undid another large change. So the net result was zero, which git was smart enough to figure out, and therefore these two changes +D and -D cancelled one another and none of them were shown. Thanks a lot!
