gitweb.cgi history not shown This does: - add a "rev.simplify_history" flag which defaults to on - it turns it off for "git whatchanged" (which thus now has real semantics outside of "git log") - it adds a command line flag ("--full-history") to turn it off for others (ie you can make "git log" and "gitk" etc get the semantics if you want to. Now, just as an example of _why_ you really really really want to simplify history by default, apply this patch, install it, and try these two command lines: gitk --full-history -- git.c gitk -- git.c and compare the output. So with this, you can also now do git whatchanged -p -- gitweb.cgi git log -p --full-history -- gitweb.cgi and it will show the old history of gitweb.cgi, even though it's not relevant to the _current_ state of the name "gitweb.cgi" NOTE NOTE NOTE! It will still actually simplify away merges that didn't change anything at all into either child. That creates these bogus strange discontinuities if you look at it with "gitk" (look at the --full-history gitk output for git.c, and you'll see a few strange cases). So the whole "--parent" thing ends up somewhat bogus with --full-history because of this, but I'm not sure it's worth even worrying about. I don't think you'd ever want to really use "--full-history" with the graphical representation, I just give it as an example exactly to show _why_ doing so would be insane. I think this is trivial enough and useful enough to be worth merging into the stable branch. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

Allow non-developer to clone, checkout and fetch more easily. The code that uses committer_info() in reflog can barf and die whenever it is asked to update a ref. And I do not think calling ignore_missing_committer_name() upfront like recent receive-pack did in the aplication is a reasonable workaround. What the patch does. - git_committer_info() takes one parameter. It used to be "if this is true, then die() if the name is not available due to bad GECOS, otherwise issue a warning once but leave the name empty". The reason was because we wanted to prevent bad commits from being made by git-commit-tree (and its callers). The value 0 is only used by "git var -l". Now it takes -1, 0 or 1. When set to -1, it does not complain but uses the pw->pw_name when name is not available. Existing 0 and 1 values mean the same thing as they used to mean before. 0 means issue warnings and leave it empty, 1 means barf and die. - ignore_missing_committer_name() and its existing caller (receive-pack, to set the reflog) have been removed. - git-format-patch, to come up with the phoney message ID when asked to thread, now passes -1 to git_committer_info(). This codepath uses only the e-mail part, ignoring the name. It used to barf and die. The other call in the same program when asked to add signed-off-by line based on committer identity still passes 1 to make sure it barfs instead of adding a bogus s-o-b line. - log_ref_write in refs.c, to come up with the name to record who initiated the ref update in the reflog, passes -1. It used to barf and die. The last change means that git-update-ref, git-branch, and commit walker backends can now be used in a repository with reflog by somebody who does not have the user identity required to make a commit. They all used to barf and die. I've run tests and all of them seem to pass, and also tried "git clone" as a user whose GECOS is empty -- git clone works again now (it was broken when reflog was enabled by default). But this definitely needs extra sets of eyeballs. Signed-off-by: Junio C Hamano <junkio@cox.net>

Add "named object array" concept We've had this notion of a "object_list" for a long time, which eventually grew a "name" member because some users (notably git-rev-list) wanted to name each object as it is generated. That object_list is great for some things, but it isn't all that wonderful for others, and the "name" member is generally not used by everybody. This patch splits the users of the object_list array up into two: the traditional list users, who want the list-like format, and who don't actually use or want the name. And another class of users that really used the list as an extensible array, and generally wanted to name the objects. The patch is fairly straightforward, but it's also biggish. Most of it really just cleans things up: switching the revision parsing and listing over to the array makes things like the builtin-diff usage much simpler (we now see exactly how many members the array has, and we don't get the objects reversed from the order they were on the command line). One of the main reasons for doing this at all is that the malloc overhead of the simple object list was actually pretty high, and the array is just a lot denser. So this patch brings down memory usage by git-rev-list by just under 3% (on top of all the other memory use optimizations) on the mozilla archive. It does add more lines than it removes, and more importantly, it adds a whole new infrastructure for maintaining lists of objects, but on the other hand, the new dynamic array code is pretty obvious. The change to builtin-diff-tree.c shows a fairly good example of why an array interface is sometimes more natural, and just much simpler for everybody.
