First cut at libifying revlist generation This really just splits things up partially, and creates the interface to set things up by parsing the command line. No real code changes so far, although the parsing of filenames is a bit stricter. In particular, if there is a "--", then we do not accept any filenames before it, and if there isn't any "--", then we check that _all_ paths listed are valid, not just the first one. The new argument parsing automatically also gives us "--default" and "--not" handling as in git-rev-parse.

git-rev-list libification: rev-list walking This actually moves the "meat" of the revision walking from rev-list.c to the new library code in revision.h. It introduces the new functions void prepare_revision_walk(struct rev_info *revs); struct commit *get_revision(struct rev_info *revs); to prepare and then walk the revisions that we have.

#define TREECHANGE (1u<<2)
Rip out merge-order and make "git log <paths>..." work again. Well, assuming breaking --merge-order is fine, here's a patch (on top of the other ones) that makes git log <filename> actually work, as far as I can tell. I didn't add the logic for --before/--after flags, but that should be pretty trivial, and is independent of this anyway. Signed-off-by: Junio C Hamano <junkio@cox.net>

#define SHOWN (1u<<3)
git-log (internal): more options. This ports the following options from rev-list based git-log implementation: * -<n>, -n<n>, and -n <n>. I am still wondering if we want this natively supported by setup_revisions(), which already takes --max-count. We may want to move them in the next round. Also I am not sure if we can get away with not setting revs->limited when we set max-count. The latest rev-list.c and revision.c in this series do not, so I left them as they are. * --pretty and --pretty=<fmt>. * --abbrev=<n> and --no-abbrev. The previous commit already handles time-based limiters (--since, --until and friends). The remaining things that rev-list based git-log happens to do are not useful in a pure log-viewing purposes, and not ported: * --bisect (obviously). * --header. I am actually in favor of doing the NUL terminated record format, but rev-list based one always passed --pretty, which defeated this option. Maybe next round. * --parents. I do not think of a reason a log viewer wants this. The flag is primarily for feeding squashed history via pipe to downstream tools. Signed-off-by: Junio C Hamano <junkio@cox.net>

Splitting rev-list into revisions lib, end of beginning. This makes the rewrite easier to validate in that revision flag parsing and warlking part are now all in rev_info structure. Signed-off-by: Junio C Hamano <junkio@cox.net>
