Christian Couder 663a8566be replace info: rename 'full' to 'long' and clarify in-code symbols
Enum names SHORT/MEDIUM/FULL were too broad to be descriptive.  And
they clashed with built-in symbols on platforms like Windows.
Clarify by giving them REPLACE_FORMAT_ prefix.

Rename 'full' format in "git replace --format=<name>" to 'long', to
match others (i.e. 'short' and 'medium').

Christian Couder 769a4fa463 builtin/replace: unset read_replace_refs
When checking to see if some objects are of the same type
and when displaying the type of objects, git replace uses
the sha1_object_info() function.

Unfortunately this function by default respects replace
refs, so instead of the type of a replaced object, it
gives the type of the replacement object which might
be different.

To fix this bug, and because git replace should work at a
level before replacement takes place, let's unset the
read_replace_refs global variable at the beginning of
cmd_replace().

Christian Couder bbbb4afc26 t6050: add tests for listing with --format
This patch adds tests for "git replace -l --format=<fmt>".

'short', 'medium' and 'full' are the only allowed values
for <fmt>.

'short' is the same as with no --format option.
Tests for 'medium' and 'full' are the most needed.

Christian Couder 1f7117ef7a sha1_file: perform object replacement in sha1_object_info_extended()
sha1_object_info_extended() should perform object replacement
if it is needed.

The simplest way to do that is to make it call
lookup_replace_object_extended().

And now its "unsigned flags" parameter is used as it is passed
to lookup_replace_object_extended().

Christian Couder 303c5d65c9 t6050: show that git cat-file --batch fails with replace objects
When --batch is passed to git cat-file, the sha1_object_info_extended()
function is used to get information about the objects passed to
git cat-file.

Unfortunately sha1_object_info_extended() doesn't take care of
object replacement properly, so it will often fail with a
message like this:

$ echo a3fb2e1845a1aaf129b7975048973414dc172173 | git cat-file --batch
a3fb2e1845a1aaf129b7975048973414dc172173 commit 231
fatal: object a3fb2e1845a1aaf129b7975048973414dc172173 change size!?

Breaks in a test assertion's && chain can potentially hide

Commands intended to fail should be marked with !, test_must_fail, or

Christian Couder d212cef936 t6050 (replace): fix bogus "fetch branch with replacement" test
The test was missing some "&&" at the end of some lines and it
was wrong because, as the replacement refs were not fetched,
the commits from the parallel branch should not show up. This
was found by Elijah Newren.

This is fixed by checking that after the branch from HASH6 is
fetched, the commits from the parallel branch don't show up,
and then by fetching the replacement refs and checking that
they do show up afterwards.

Jonathan Nieder 18a8269242 tests: subshell indentation stylefix
Format the subshells introduced by the previous patch (Several tests:
cd inside subshell instead of around, 2010-09-06) like so:

	(
		cd subdir &&
		...
	) &&

This is generally easier to read and has the nice side-effect that
this patch will show what commands are used in the subshell, making
it easier to check for lost environment variables and similar
behavior changes.

  parse_object: pass on the original sha1, not the replaced one

Nguyễn Thái Ngọc Duy 2e3400c052 parse_object: pass on the original sha1, not the replaced one
Commit 0e87c36 (object: call "check_sha1_signature" with the
replacement sha1) changed the first argument passed to
parse_object_buffer() from "sha1" to "repl". With that change,
the returned obj pointer has the replacement SHA1 in obj->sha1,
not the original one.

But when using lookup_commit() and then parse_commit() on a
commit, we get an object pointer with the original sha1, but
the commit content comes from the replacement commit.

So the result we get from using parse_object() is different
from the we get from using lookup_commit() followed by
parse_commit().

It looks much simpler and safer to fix this inconsistency by
passing "sha1" to parse_object_bufer() instead of "repl".

The commit comment should be used to tell the the replacement
commit is replacing another commit and why. So it should be
easy to see that we have a replacement commit instead of an
original one.

And it is not a problem if the content of the commit is not
consistent with the sha1 as cat-file piped to hash-object can
be used to see the difference.

Christian Couder 6476b38b1f replace: use a GIT_NO_REPLACE_OBJECTS env variable
This has the same effect as --no-replace-objects option; git ignores the
replace refs.  When --no-replace-objects option is passed to git, this
environment variable is set to "1" and exported to subprocesses in order
to propagate the same setting.

It is useful for example for scripts, as the git commands used in them can
now be aware that they must not read replace refs.

Christian Couder b0fa7ab51b git: add --no-replace-objects option to disable replacing
Commit dae556b (environment: add global variable to disable replacement)
adds a variable to enable/disable replacement, and it is enabled by
default for most commands.

So there is no way to disable it for some commands, which is annoying
when we want to get information about a commit that has been replaced.

For example:

$ git cat-file -p N

would output information about the replacement commit if commit N is
replaced.

With the "--no-replace-objects" option that this patch adds it is
possible to get information about the original commit using:

$ git --no-replace-objects cat-file -p N

While at it, let's add some documentation about this new option in the
"git replace" man page too.

Christian Couder 4e65b538ac t6050: check pushing something based on a replaced commit
When using something like:

$ git push $there 04a8c^2:master

we need to parse 04a8c to find its second parent and then start
discussing what object to send with the other end.  "04a8c^2" is a direct
user input and should mean the same commit as git show "04a8c^2" would
give the user, so it obviously needs to obey the replace rules (making
04a8c parsed), but the object transfer should not look at replace at all.

This patch adds some tests to check that the above is working well.

This command can only be used now to list replace refs in
"refs/replace/" and to delete them.

The option to list replace refs is "-l".
The option to delete replace refs is "-d".

are working.

The code has been copied from "builtin-tag.c" by Kristian Høgsberg

It may be that we should just refuse to tag a replaced object. But
in this case we should probably give a meaningfull error message
