When a merge conflicts, there are often common lines that are not really
common, such as empty lines or lines containing a single curly bracket.
With XDL_MERGE_ZEALOUS_ALNUM, we use the following heuristics: when a
hunk does not contain any letters or digits, it is treated as conflicting.
In other words, a conflict which used to look like this:
<<<<<<<
a = 1;
=======
output();
>>>>>>>
}
}
}
<<<<<<<
output();
=======
b = 1;
>>>>>>>
will look like this with ZEALOUS_ALNUM:
<<<<<<<
a = 1;
}
}
}
output();
=======
output();
}
}
}
b = 1;
>>>>>>>
To demonstrate this, git-merge-file has been switched from
XDL_MERGE_ZEALOUS to XDL_MERGE_ZEALOUS_ALNUM.

When a merge conflicts, there are often less than three common lines
between two conflicting regions.
Since a conflict takes up as many lines as are conflicting, plus three
lines for the commit markers, the output will be shorter (and thus,
simpler) in this case, if the common lines will be merged into the
conflicting regions.
This patch merges up to three common lines into the conflicts.
For example, what looked like this before this patch:
<<<<<<<
if (a == 1)
=======
if (a != 0)
>>>>>>>
{
int i;
<<<<<<<
a = 0;
=======
a = !a;
>>>>>>>
will now look like this:
<<<<<<<
if (a == 1)
{
int i;
a = 0;
=======
if (a != 0)
{
int i;
a = !a;
>>>>>>>

Add support for new option -nohtml to quot_cec and quot_upr
subroutines, to have output not wrapped in HTML tags. This makes
those subroutines suitable to quoting attributes values, and for plain
text output quoting. Currently this API is not used yet.
While at it fix whitespace, and use ';' as delimiter, not separator.
The option to not wrap quot_cec output in HTML tag were proposed
originally in patch:
"Don't open a XML tag while another one is already open"
Message-ID: <20080216191628.GK30676@schiele.dyndns.org>
by Robert Schiele. Originally the parameter was named '-notag', was
also supportted by esc_html (but not esc_path) which passed it down to
quot_cec. Mentioned patch was meant to fix the bug Martin Koegler
reported in his mail
"Invalid html output repo.or.cz (alt-git.git)"
Message-ID: <20080216130037.GA14571@auto.tuwien.ac.at>
which was fixed in different way (do not use esc_html to escape and
quote HTML attributes).

Do not use esc_html to escape [title] _attribute_ of a HTML element,
and quote unprintable characters. Replace unprintable characters by
'?' and use CGI method to generate HTML element and do the escaping.
This caused bug noticed by Martin Koegler,
Message-ID: <20080216130037.GA14571@auto.tuwien.ac.at>
that for bad commit encoding in author name, the title attribute (here
to show full, not shortened name) had embedded HTML code in it, result
of quoting unprintable characters the gitweb/HTML way. This of course
broke the HTML, causing page being not displayed in XML validating web

When deciding if gitk or git-log should be used to visualize the current
state, the environment variable DISPLAY was checked. Now, we check
MSYSTEM (for MinGW32/MSys) and SECURITYSESSIONID (for MacOSX) in addition.
Note that there is currently no way to ssh into MinGW32, and that
SECURITYSESSIONID is not set automatically on MacOSX when ssh'ing into it.
So this patch should be safe.

you do not get any indication of error. If you are careful, you

displayed, but that is about it. If you run the "show" command
without pager, however, you will see the error:

Because we spawn the pager as the foreground process and feed
its input via pipe from the real command, we cannot affect the
exit status the shell sees from git command when the pager is in
use (I think there is not much gain we can have by working it
around, though). But at least it may make sense to show the
error message to the user sitting in front of the pager.

what I originally posted, which I took.]

Documentation/git-reset: Add an example of resetting selected paths
Documentation/git-reset: don't mention --mixed for selected-paths reset
Documentation/git-reset:
When you are switching to a branch that is marked to merge from
somewhere else, e.g. when you have:
[branch "next"]
remote = upstream
merge = refs/heads/next
[remote "upstream"]
url = ...
fetch = refs/heads/*:refs/remotes/linus/*
and you say "git checkout next", the branch you checked out
may be behind, and you may want to update from the upstream
before continuing to work.
This patch makes the command to check the upstream (in this
example, "refs/remotes/linus/next") and our branch "next", and:
(1) if they match, nothing happens;
(2) if you are ahead (i.e. the upstream is a strict ancestor
of you), one line message tells you so;
(3) otherwise, you are either behind or you and the upstream
have forked. One line message will tell you which and
then you will see a "log --pretty=oneline --left-right".
We could enhance this with an option that tells the command to
check if there is no local change, and automatically fast
forward when you are truly behind. But I ripped out that change
because I was unsure what the right way should be to allow users
to control it (issues include that checkout should not become
automatically interactive).

The only differences in behavior should be:
- git checkout -m with non-trivial merging won't print out
merge-recursive messages (see the change in t7201-co.sh)
- git checkout -- paths... will give a sensible error message if
HEAD is invalid as a commit.
- some intermediate states which were written to disk in the shell
version (in particular, index states) are only kept in memory in
this version, and therefore these can no longer be revealed by
later write operations becoming impossible.
- when we change branches, we discard MERGE_MSG, SQUASH_MSG, and
rr-cache/MERGE_RR, like reset always has.
I'm not 100% sure I got the merge recursive setup exactly right; the
base for a non-trivial merge in the shell code doesn't seem
theoretically justified to me, but I tried to match it anyway, and the
tests all pass this way.
Other than these items, the results should be identical to the shell
version, so far as I can tell.

There were several points where we looked at the HEAD
commit; for initial commits, this is meaningless. So instead
we:
- show staged status data as a diff against the empty tree
instead of HEAD
- show file diffs as creation events
- use "git rm --cached" to revert instead of going back to
the HEAD commit
We magically reference the empty tree to implement this.

If fast-import is in the middle of crashing due to a protocol error
or something like that then it can be very useful to have the mark
table and all objects up until that point be available for a new
import to resume from.
Currently we just close the active packfile, unkeep all of our
newly created packfiles (so they can be deleted), and dump the
marks table to a temporary file.
We don't attempt to update the refs/tags that the process has in
memory as much of that data can be found in the crash report and I'm
not sure it would be the right thing to do under every type of crash.

If annotated tags were created they exist in a different namespace
within the fast-import process' internal memory tables so we did
not export them in the inactive branch table. Now they are written
