* mailmap: use higher level string list functionsStefan Beller2014-12-04
| | | | | | | | | | | | | No functional changes intended. This commit makes use of higher level and better documented functions of the string list API, so the code is more understandable. Note that also the required computational amount should not change in principal as we need to look up the item no matter if it is already part of the list or not. Once looked up, insertion comes for free. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | On some systems (e.g. MinGW 4.0), string.h has only inline definition of strcasecmp and no non-inline implementation is supplied anywhere, which is, eh, "unusual". We cannot take an address of such a function to store it in namemap.cmp. Work it around by introducing our own level of indirection. Signed-off-by: Junio C Hamano <gitster@pobox.com>

As a result, when we subtract the linelen from the total len, we end up with (unsigned long)-1 bytes left in the buffer, and we start reading random junk from memory. We could fix it with: unsigned long linelen = end - buf + !!*end; but let's take a step back for a moment. It's questionable in the first place for a function that takes a buffer and length to be using strchrnul. But it works because we only have one caller (and are only likely to ever have this one), which is handing us data from read_sha1_file. Which means that it's always NUL-terminated. Instead of tightening the assumptions to make the buffer/length pair work for a caller that doesn't actually exist, let's let loosen the assumptions to what the real caller has: a modifiable, NUL-terminated string. This makes the code simpler and shorter (because we don't have to correlate strchrnul with the length calculation), correct (because the code with the off-by-one just goes away), and more efficient (we can drop the extra allocation we needed to create NUL-terminated strings for each line, and just terminate in place).

Because we do use case insensitive version of string list to manage these entries, there is no need to do this, and worse yet, downcasing the rewritten/canonical e-mail read from the .mailmap file loses information. Stop doing that, and also make the string list used to keep multiple names for an mailmap entry case insensitive (the code that uses the list, lookup_prefix(), expects a case insensitive match).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>
* | mailmap: default mailmap.blob in bare repositoriesJeff King2012-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | mailmap: clean up read_mailmap error handlingJeff King2012-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.

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.
