Previous address : http://thread.gmane.org/gmane.comp.version-control.git/243919. I do not use positional initializer because it is not allowed to use variable in it. I don't know if it's ok to use this redundant way to initialize "list". Thanks for the resubmission. A few comments below, but I don't think you need to resubmit. What is important is that you have had a taste of the review process on this project, and the GSoC mentors have had a chance to observe your abilities and reviewer interaction. A better use of your time now would be to make your GSoC proposal and converse with the mentors. > I cannot find -v flag in documentation you indicated in last email so I use set-prefix to add it into prefix. Sorry for the confusion. As Junio pointed out [1], I meant the -v option of "git format-patch", not "git format-email" (which doesn't exist).

I know it's important to get known about git_config first and have read documentation about it. But I am really confused about how to understand code of git_config. When user type in git config in terminal, what is the execute order of functions? How git config influence other git command? Does program read config file every time when they execuate config-related command? You will get a better response if you ask these questions in a new email thread rather than re-using this one. Choose a subject for your email which indicates clearly that you have questions about that particular GSoC project, address it to the git mailing list, and cc: the mentors of that project. > Thank you, > > Yao > > diff --git a/branch.c b/branch.c > index 723a36b..1df30c7 100644 > --- a/branch.c > +++ b/branch.c > @@ -53,7 +53,33 @@ void install_branch_config(int flag, const char *local, const char *origin, cons > int remote_is_branch = starts_with(remote, "refs/heads/"); > struct strbuf key = STRBUF_INIT; > int rebasing = should_setup_rebase(origin); > - > + struct print_list { > + const char *print_str; > + const char *arg2; > + const char *arg3; > + } ; > + struct print_list target; This should be 'const struct print_list *target'.

It disturbs me to see that .arg3 does not get initialized in most of these cases, yet it is accessed below by printf_ln(). Code analysis tools are likely to complain about accessing an uninitialized value. One way you could put this into the initializer would be to use a constant expression to indicate which variable to pass to printf_ln(). Something like this: struct print_list { const char *print_str; int use_shortname; int use_origin; } print_list[][2][2] = { N_("Branch %s ..."), 0, 0, ... N_("Branch %s ..."), 1, 0, ... } printf_ln(_(target->print_str), local, target->use_shortname ? shortname : remote, target->use_origin ? origin : NULL); To make it clearer, use named constants rather than 0 and 1. NOTE: I am *not* suggesting that you resubmit with this change. It's getting ugly and bordering on being too complex and difficult to read. As noted above, your time is probably better spent working on your GSoC proposal. > if (remote_is_branch > && !strcmp(local, shortname) > && !origin) { > @@ -77,29 +103,8 @@ void install_branch_config(int flag, const char *local, const char *origin, cons > strbuf_release(&key); > > if (flag & BRANCH_CONFIG_VERBOSE) { > - if (remote_is_branch && origin) > - printf_ln(rebasing ? > - _("Branch %s set up to track remote branch %s from %s by rebasing.") : > - _("Branch %s set up to track remote branch %s from %s."), > - local, shortname, origin); > - else if (remote_is_branch && !origin) > - printf_ln(rebasing ? > - _("Branch %s set up to track local branch %s by rebasing.") : > - _("Branch %s set up to track local branch %s."), > - local, shortname); > - else if (!remote_is_branch && origin) > - printf_ln(rebasing ? > - _("Branch %s set up to track remote ref %s by rebasing.") : > - _("Branch %s set up to track remote ref %s."), > - local, remote); > - else if (!remote_is_branch && !origin) > - printf_ln(rebasing ? > - _("Branch %s set up to track local ref %s by rebasing.") : > - _("Branch %s set up to track local ref %s."), > - local, remote); > - else > - die("BUG: impossible combination of %d and %p", > - remote_is_branch, origin); > + target = list[!!remote_is_branch][!!origin][!!rebasing]; With the suggestion above of making 'target' a pointer to the struct, this would become: target = &list[...][...][...]; > + printf_ln (_(target.print_str), local, target.arg2, target.arg3); Style: whitespace: printf_ln(...)
