Add 'git-rev-parse' helper script It's an incredibly cheesy helper that changes human-readable revision arguments into the git-rev-list argument format. You can use it to do something like this: git-rev-list --pretty $(git-rev-parse --default HEAD "$@") which is what git-log-script will become. Here git-rev-parse will then allow you to use arguments like "v2.6.12-rc5.." or similar human-readable ranges. It's really quite stupid: "a..b" will be converted into "a" and "^b" if "a" and "b" are valid object pointers. And the "--default" case will be used if nothing but flags have been seen, so that you can default to a certain argument if there are no other ranges.

#include "cache.h"
Make rev-parse understand "extended sha1" syntax You can say "HEAD.p" for the "parent of HEAD". It nests, so HEAD.p2.p means parent of second parent of HEAD (which obviously depends on HEAD being a merge).

#include "commit.h"
Add "--all" flag to rev-parse that shows all refs And make git-rev-list just silently ignore non-commit refs if we're not asking for all objects.

[PATCH] Help scripts that use git-rev-parse to grok args with SP/TAB/LF The git-rev-parse command uses LF to separate each argument it parses, so its users at least need to set IFS to LF to be able to handle filenames with embedded SPs and TABs. Some commands, however, can take and do expect arguments with embedded LF, notably, "-S" (pickaxe) of diff family, so even this workaround does not work for them. When --sq flag to git-rev-parse is given, instead of showing one argument per line, it outputs arguments quoted for consumption with "eval" by the caller, to remedy this situation. As an example, this patch converts git-whatchanged to use this new feature. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

git-rev-parse: add "--not" flag to mark subsequent heads negative If you have two lists of heads, and you want to see ones reachable from list $a but not from list $b, just do git-rev-list $(git-rev-parse $a --not $b) which is useful for both bisecting (where "b" would be the list of known good revisions, and "a" would be the latest found bad head) and for just seeing what the difference between two sets of heads are if you want to generate a pack-file for the difference.

Update rev-parse flags list. I haven't audited the rev-parse users, but I am having a feeling that many of them would choke when they expect a couple of SHA1 object names and malicious user feeds them "--max-count=6" or somesuch to shoot himself in the foot. Anyway, this adds a couple of missing parameters that affect the list of revs to be returned from rev-list, not the flags that affect how they are presented by rev-list. I think that is the intention, but I am not quite sure. Signed-off-by: Junio C Hamano <junkio@cox.net>

Add 'git-rev-parse' helper script It's an incredibly cheesy helper that changes human-readable revision arguments into the git-rev-list argument format. You can use it to do something like this: git-rev-list --pretty $(git-rev-parse --default HEAD "$@") which is what git-log-script will become. Here git-rev-parse will then allow you to use arguments like "v2.6.12-rc5.." or similar human-readable ranges. It's really quite stupid: "a..b" will be converted into "a" and "^b" if "a" and "b" are valid object pointers. And the "--default" case will be used if nothing but flags have been seen, so that you can default to a certain argument if there are no other ranges.
