Antoine Pelisse	ea02ffa385	mailmap: simplify map_user() interface Simplify map_user(), mostly to avoid copies of string buffers. It also simplifies caller functions. map_user() directly receive pointers and length from the commit buffer as mail and name. If mapping of the user and mail can be done, the pointer is updated to a new location. Lengths are also updated if necessary. The caller of map_user() can then copy the new email and name if necessary. Signed-off-by: Antoine Pelisse <apelisse@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Junio C Hamano	388c7f8a27	mailmap: remove email copy and length limitation In map_user(), we have email pointer that points at the beginning of an e-mail address, but the buffer is not terminated with a NUL after the e-mail address. It typically has ">" after the address, and it could have even more if it comes from author/committer line in a commit object. Or it may not have ">" after it. We used to copy the e-mail address proper into a temporary buffer before asking the string-list API to find the e-mail address in the mailmap, because string_list_lookup() function only takes a NUL terminated full string. Introduce a helper function lookup_prefix that takes the email pointer and the length, and finds a matching entry in the string list used for the mailmap, by doing the following: - First ask string_list_find_insert_index() where in its sorted list the e-mail address we have (including the possible trailing junk ">...") would be inserted. - It could find an exact match (e.g. we had a clean e-mail address without any trailing junk). We can return the item in that case. - Or it could return the index of an item that sorts after the e-mail address we have. - If we did not find an exact match against a clean e-mail address, then the record we are looking for in the mailmap has to exist before the index returned by the function (i.e. "email>junk" always sorts later than "email"). Iterate, starting from that index, down the map->items[] array until we find the exact record we are looking for, or we see a record with a key that definitely sorts earlier than the e-mail we are looking for (i.e. when we are looking for "email" in "email>junk", a record in the mailmap that begins with "emaik" strictly sorts before "email", if such a key existed in the mailmap). This, together with the earlier enhancement to support case-insensitive sorting, allow us to remove an extra copy of email buffer to downcase it. A part of this is based on Antoine Pelisse's previous work. Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Jeff King	8c473cecfd	mailmap: default mailmap.blob in bare repositories The motivation for mailmap.blob is to let users of bare repositories use the mailmap feature, as they would not have a checkout containing the .mailmap file. We can make it even easier for them by just looking in HEAD:.mailmap by default. We can't know for sure that this is where they would keep a mailmap, of course, but it is the best guess (and it matches the non-bare behavior, which reads from HEAD:.mailmap in the working tree). If it's missing, git will silently ignore the setting. We do not do the same magic in the non-bare case, because: 1. In the common case, HEAD:.mailmap will be the same as the .mailmap in the working tree, which is a no-op. 2. In the uncommon case, the user has modified .mailmap but not yet committed it, and would expect the working tree version to take precedence.

Jeff King	938a60d64f	mailmap: clean up read_mailmap error handling The error handling for the read_mailmap function is odd. It returns 1 on error, rather than -1. And it treats a non-existent mailmap as an error, even though there is no reason that one needs to exist. Unless some other mailmap source loads successfully, in which case the original error is completely masked. This does not cause any bugs, however, because no caller bothers to check the return value, anyway. Let's make this a little more robust to real errors and less surprising for future callers that do check the error code: 1. Return -1 on errors. 2. Treat a missing entry (e.g., no mailmap.file given), ENOENT, or a non-existent blob (for mailmap.blob) as "no error". 3. Complain loudly when a real error (e.g., a transient I/O error, no permission to open the mailmap file, missing or corrupted blob object, etc) occurs.

Jeff King	086109006f	mailmap: support reading mailmap from blobs In a bare repository, there isn't a simple way to respect an in-tree mailmap without extracting it to a temporary file.

Jeff King	7c8ce308d3	mailmap: refactor mailmap parsing for non-file sources The read_single_mailmap function opens a mailmap file and parses each line. In preparation for having non-file mailmaps, let's pull out the line-parsing logic into its own function (read_mailmap_line), and rename the file-parsing function to match (read_mailmap_file).

Romain Francoise	3174bc5ccf	mailmap: avoid out-of-bounds memory access AddressSanitizer (http://clang.llvm.org/docs/AddressSanitizer.html) complains of a one-byte buffer underflow in parse_name_and_email() while running the test suite. And indeed, if one of the lines in the mailmap begins with '<', we dereference the address just before the beginning of the buffer when looking for whitespace to remove, before checking that we aren't going too far. So reverse the order of the tests to make sure that we don't read outside the buffer. Signed-off-by: Romain Francoise <romain@orebokech.com> Signed-off-by: Jeff King <peff@peff.net>	12 years ago
Junio C Hamano	f026358ef2	mailmap: always return a plain mail address from map_user() 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>	13 years ago

Jim Meyering	d8d2eb7d6b	mailmap: fix use of freed memory 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.

Linus Torvalds	2af202be3d	Fix various sparse warnings in the git source code 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.
