| * rerere: never renormalizeJonathan Nieder2010-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | plain rerere performs three tasks; let us consider how the new merge.renormalize option should apply to each. After an unsuccessful merge, rerere records conflict hunks from the work tree under .git/rr-cache. If the merge was performed with merge.renormalize enabled, both sides of the conflict hunk use the current work tree’s end-of-line and smudge rules; there is not really much of a choice. After a successful manual resolution, rerere records the postimage. Here, also, the file will be in the current work tree’s canonical format and there is not much to do about it. When encountering that conflict again, merge looks up the preimage and postimage using the conflict hunk as a key and runs a three-way merge to apply that resolution to the work tree. Since the conflict hunk used the current work tree’s canonical format, chances are the version in the work tree, the preimage, and the postimage will, too. In fact using the merge.renormalize machinery is exactly the wrong thing to do, since its result has been run through convert_to_git and therefore is not suitable for writing to the work tree. The only affected caller is "git merge".

| * ll-merge: let caller decide whether to renormalizeJonathan Nieder2010-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a “renormalize” bit to the ll-merge options word so callers can decide on a case-by-case basis whether the merge is likely to have overlapped with a change in smudge/clean rules. This reveals a few commands that have not been taking that situation into account, though it does not fix them. No functional change intended.

| * | rerere: fix overeager gcSZEDER Gábor2010-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'rerere gc' prunes resolutions of conflicted merges that occurred long time ago, and when doing so it takes the creation time of the conflicted automerge results into account. This can cause the loss of frequently used conflict resolutions (e.g. long-living topic branches are merged into a regularly rebuilt integration branch (think of git's pu)) when they become old enough to exceed 'rerere gc's threshold. To prevent the loss of valuable merge resolutions 'rerere' will (1) update the timestamp of the recorded conflict resolution (i.e. 'postimage') each time when encountering and resolving the same merge conflict, and (2) take this timestamp, i.e. the time of the last usage into account when gc'ing.

|/ | | | | | | | | | | | | | | | | | | Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.

* ll_merge(): add ancestor label parameter for diff3-style outputJonathan Nieder2010-03-20
| | | | | | | | | | | | | | | | Commands using the ll_merge() function will present conflict hunks imitating ‘diff3 -m’ output if the merge.conflictstyle configuration option is set appropriately. Unlike ‘diff3 -m’, the output does not include a label for the merge base on the ||||||| line of the output, and some tools misparse the conflict hunks without that. Add a new ancestor_label parameter to ll_merge() to give callers the power to rectify this situation. If ancestor_label is NULL, the output format is unchanged. All callers pass NULL for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 2d14d65 (Use a clearer style to issue commands to remote helpers, 2009-09-03) I happened to notice two changes like this: - write_in_full(helper->in, "list\n", 5); + + strbuf_addstr(&buf, "list\n"); + write_in_full(helper->in, buf.buf, buf.len); + strbuf_reset(&buf); IMHO, it would be better to define a new function, static inline ssize_t write_str_in_full(int fd, const char *str) { return write_in_full(fd, str, strlen(str)); } and then use it like this: - strbuf_addstr(&buf, "list\n"); - write_in_full(helper->in, buf.buf, buf.len); - strbuf_reset(&buf); + write_str_in_full(helper->in, "list\n"); Thus not requiring the added allocation, and still avoiding the maintenance risk of literal string lengths. These days, compilers are good enough that strlen("literal") imposes no run-time cost.

I used the following criteria when selecting the code for replacement: - it was already printing a warning for the unlink failures - it is in a function which already printing something or is called from such a function - it is in a static function, returning void and the function is only called from a builtin main function (cmd_) - it is in a function which handles emergency exit (signal handlers) - it is in a function which is obvously cleaning up the lockfiles Signed-off-by: Alex Riesen <raa.lkml@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Also, since this puts these two functions into the global namespace, rename them to rerere_path() and has_rerere_resolution(), respectively, and rename their "name" parameter to "hex", because it better reflects what that parameter actually is.

Compilation of git is probably broken on PPC too for the same reason. Turns out that the only file requiring openssl/ssl.h and openssl/err.h is imap-send.c. But only moving those problematic includes there doesn't solve the issue as it also includes cache.h which brings in the conflicting local SHA1 header file. As suggested by Jeff King, the best solution is to rename our references to SHA1 functions and structure to something git specific, and define those according to the implementation used.
