* mailmap: always return a plain mail address from map_user()Junio C Hamano2012-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | The callers of map_user() give email and name to it, and expect to get the up-to-date email and/or name to be used in their output. The function rewrites the given buffers in place. To optimize the majority of cases, the function returns 0 when it did not do anything, and it returns 1 when the caller should use the updated contents. The 'email' input to the function is terminated by '>' or a NUL (whichever comes first) for historical reasons, but when a rewrite happens, the value is replaced with the mailbox inside the <> pair. However, it failed to meet this expectation when it only rewrote the name part without rewriting the email part, and the email in the input was terminated by '>'. This causes an extra '>' to appear in the output of "blame -e", because the caller does send in '>'-terminated email, and when the function returned 1 to tell it that rewriting happened, it appends '>' that is necessary when the email part was rewritten. The patch looks bigger than it actually is, because this change makes a variable that points at the end of the email part in the input 'p' live much longer than it used to, deserving a more descriptive name. Noticed and diagnosed by Felipe Contreras and Jeff King. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | mailmap: fix use of freed memoryJim Meyering2010-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On an x86_64 system (F13-based), I ran these commands in an empty directory: git init printf '%s\n' \ '<jdoe@example.com> <jdoe@example.COM>' \ 'John <jdoe@example.com>' > .mailmap git shortlog < /dev/null Here's the result: (reading log message from standard input) *** glibc detected *** git: free(): invalid pointer: 0x0000000000f53730 *** ======= Backtrace: ========= /lib64/libc.so.6[0x31ba875676] git[0x48c2a5] git[0x4b9858] ... zsh: abort (core dumped) git shortlog What happened? Some .mailmap entry is of the <email1> <email2> form, while a subsequent one looks like "User Name <Email2>, and the two email addresses on the right are not identical but are "equal" when using a case-insensitive comparator. Then, when add_mapping is processing the latter line, new_email is NULL and we free me->email, yet do not replace it with a new strdup'd string. Thus, when later we attempt to use the buffer behind that ->email pointer, we reference freed memory. The solution is to free ->email and ->name only if we're about to replace them.

* | Fix various sparse warnings in the git source codeLinus Torvalds2009-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few remaining ones, but this fixes the trivial ones. It boils down to two main issues that sparse complains about: - warning: Using plain integer as NULL pointer Sparse doesn't like you using '0' instead of 'NULL'. For various good reasons, not the least of which is just the visual confusion. A NULL pointer is not an integer, and that whole "0 works as NULL" is a historical accident and not very pretty. A few of these remain: zlib is a total mess, and Z_NULL is just a 0. I didn't touch those. - warning: symbol 'xyz' was not declared. Should it be static? Sparse wants to see declarations for any functions you export. A lack of a declaration tends to mean that you should either add one, or you should mark the function 'static' to show that it's in file scope. A few of these remain: I only did the ones that should obviously just be made static. That 'wt_status_submodule_summary' one is debatable. It has a few related flags (like 'wt_status_use_color') which _are_ declared, and are used by builtin-commit.c. So maybe we'd like to export it at some point, but it's not declared now, and not used outside of that file, so 'static' it is in this patch.

|/ | | | | | | | | | While it makes no sense to map some email address to an empty one, doing things the other way around can be useful.

* Add map_user() and clear_mailmap() to mailmapMarius Storm-Olsen2009-02-08
| | | | | | | | | | | | | | | | | | | | | | map_user() allows to lookup and replace both email and name of a user, based on a new style mailmap file. The possible mailmap definitions are now: proper_name <commit_email> # Old style <proper_email> <commit_email> # New style proper_name <proper_email> <commit_email> # New style proper_name <proper_email> commit_name <commit_email> # New style map_email() operates the same as before, with the exception that it also will to try to match on a name passed in through the name return buffer. clear_mailmap() is needed to now clear the more complex mailmap structure.
