Dear git developers:
Allow me to describe the testing situation more detail:
First the testing repository is in
https://github.com/gawel/pyquery
my git version is 1.9.2 running on Archlinux 3.14.2
I try to track issue #74(which is closed now)
It give result False/True in version 1.2.8(good), and result False/False in
version 1.2.9(bad).
The testing script are manualscript.py and autoscript.py
Both of them implement the test case describe in issue #74.
Th only difference is that autoscript.py call sys.exit() to return the
testing value.
First we test with git-bisect manually with manualscript.py:
The testing result is shown in 'bisectmanual_manualscript'
Then we test with git-bisect manually with autoscript.py
This time we echo $? every time we execute autoscript.py, and the testing
result is shown in 'bisectmanual_autoscript'
In both situation the script give the same result, and the return value of
autoscript.py is correct, too.
However, if we use git-bisect-run with autoscript.py, it will show a
different result. The testing result is shown in 'bisectrun'.
The log shows that autoscript.py output False/False all the way.
As Mr. Couder said, there is some checkout commit that autoscript.py and
manualscript.py give different result, for example commit
d22159bb32510e9eacf6c5c2408a79792e99fe76.
If I checkout this commit outside bisect state and run manualscript.py and
autoscript.py, they both give False/True result.
So, I guess there is some problem in the checkout procedure in bisect-run, so
the commit didn't successfully checkout.
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

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
