I don't think so. I tried to run the following command many times in a row: for rev in bc1b16509cec70de7a32354026443fca777f4d7d b81a9e8a2b0d48ec0c64d6de14293dd4a680a20b d22159bb32510e9eacf6c5c2408a79792e99fe76; do git checkout $rev; python -m pyquery.autoscript; done And here is the log: $ for rev in bc1b16509cec70de7a32354026443fca777f4d7d b81a9e8a2b0d48ec0c64d6de14293dd4a680a20b d22159bb32510e9eacf6c5c2408a79792e99fe76; do git checkout $rev; python -m pyquery.autoscript; done Note: checking out 'bc1b16509cec70de7a32354026443fca777f4d7d'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b new_branch_name HEAD is now at bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) False False Previous HEAD position was bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) HEAD is now at b81a9e8... fixed issue #9 False False Previous HEAD position was b81a9e8... fixed issue #9 HEAD is now at d22159b... test pseudo classes; documentation effort False True $ for rev in bc1b16509cec70de7a32354026443fca777f4d7d b81a9e8a2b0d48ec0c64d6de14293dd4a680a20b d22159bb32510e9eacf6c5c2408a79792e99fe76; do git checkout $rev; python -m pyquery.autoscript; done Previous HEAD position was d22159b... test pseudo classes; documentation effort HEAD is now at bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) False False Previous HEAD position was bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) HEAD is now at b81a9e8... fixed issue #9 False False Previous HEAD position was b81a9e8... fixed issue #9 HEAD is now at d22159b... test pseudo classes; documentation effort False True $ for rev in bc1b16509cec70de7a32354026443fca777f4d7d b81a9e8a2b0d48ec0c64d6de14293dd4a680a20b d22159bb32510e9eacf6c5c2408a79792e99fe76; do git checkout $rev; python -m pyquery.autoscript; done Previous HEAD position was d22159b... test pseudo classes; documentation effort HEAD is now at bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) False False Previous HEAD position was bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) HEAD is now at b81a9e8... fixed issue #9 False False Previous HEAD position was b81a9e8... fixed issue #9 HEAD is now at d22159b... test pseudo classes; documentation effort False False $ for rev in bc1b16509cec70de7a32354026443fca777f4d7d b81a9e8a2b0d48ec0c64d6de14293dd4a680a20b d22159bb32510e9eacf6c5c2408a79792e99fe76; do git checkout $rev; python -m pyquery.autoscript; done Previous HEAD position was d22159b... test pseudo classes; documentation effort HEAD is now at bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) False False Previous HEAD position was bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) HEAD is now at b81a9e8... fixed issue #9 False False Previous HEAD position was b81a9e8... fixed issue #9 HEAD is now at d22159b... test pseudo classes; documentation effort False True $ for rev in bc1b16509cec70de7a32354026443fca777f4d7d b81a9e8a2b0d48ec0c64d6de14293dd4a680a20b d22159bb32510e9eacf6c5c2408a79792e99fe76; do git checkout $rev; python -m pyquery.autoscript; done Previous HEAD position was d22159b... test pseudo classes; documentation effort HEAD is now at bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) False False Previous HEAD position was bc1b165... created a .gitignore file(which is almost a copy of .hgignore with some minor changes and comments) HEAD is now at b81a9e8... fixed issue #9 False False Previous HEAD position was b81a9e8... fixed issue #9 HEAD is now at d22159b... test pseudo classes; documentation effort False False As you can see the result of running the autoscript.py on commit d22159b is sometimes "False False" and sometimes "False True".

That is weird. Yeah but I doubt it is a git bisect problem or a git checkout problem. It looks like it is a cleanup problem, because it looks much more stable with: for rev in bc1b16509cec70de7a32354026443fca777f4d7d b81a9e8a2b0d48ec0c64d6de14293dd4a680a20b d22159bb32510e9eacf6c5c2408a79792e99fe76; do git checkout $rev; git clean -dfx; cp ../testresult/autoscript.py pyquery/; python -m pyquery.autoscript; done Best, Christian. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
