When DEFAULT_GIT_TEMPLATE_DIR is specified as a relative path,
init-db made it relative to exec_path using prefix_path(), which
is wrong. prefix_path() is about a file inside the work tree.
There was a similar misuse in config.c that takes relative
ETC_GITCONFIG path. Noticed by Junio C Hamano.
We concatenate the paths manually. (prefix_filename() won't do
because it expects a prefix with a trailing '/'.)

"git-help--browse" helper is to launch a browser of the user's choice
to view the HTML version of git documentation for a given command. It
used to take the name of a command, convert it to the path of the
documentation by prefixing the directory name and appending the
".html" suffix, and start the browser on the path.
This updates the division of labor between the caller in help.c and
git-help--browser helper. The helper is now responsible for launching
a browser of the user's choice on given URLs, and it is the caller's
responsibility to tell it the paths to documentation files.
This is in preparation to reuse the logic to choose user's preferred
browser in instaweb.
The helper had a provision for running it without any command name, in
which case it showed the toplevel "git(7)" documentation, but the
caller in help.c never makes such a call. The helper now exits with a
usage message when no path is given.

When we process "foo/" entries in gitignore files on a system
that does not have d_type member in "struct dirent", the earlier
implementation ran lstat(2) separately when matching with
entries that came from the command line, in-tree .gitignore
files, and $GIT_DIR/info/excludes file.
This optimizes it by delaying the lstat(2) call until it becomes
absolutely necessary.
The initial idea for this change was by Jeff King, but I
optimized it further to pass pointers to around.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
A pattern "foo/" in the exclude list did not match directory
"foo", but a pattern "foo" did. This attempts to extend the
exclude mechanism so that it would while not matching a regular
file or a symbolic link "foo". In order to differentiate a
directory and non directory, this passes down the type of path
being checked to excluded() function.
A downside is that the recursive directory walk may need to run
lstat(2) more often on systems whose "struct dirent" do not give
the type of the entry; earlier it did not have to do so for an
excluded path, but we now need to figure out if a path is a
directory before deciding to exclude it. This is especially bad
because an idea similar to the earlier CE_UPTODATE optimization
to reduce number of lstat(2) calls would by definition not apply
to the codepaths involved, as (1) directories will not be
registered in the index, and (2) excluded paths will not be in
the index anyway.

An incorrect command "git mv subdir /outer/space" threw the
subdirectory to outside of the repository and then noticed that
/outer/space/subdir/ would be outside of the repository. The
error checking is backwards.
This fixes the issue by being careful about use of the return
value of get_pathspec(). Since the implementation already has
handcrafted loop to munge each path on the command line, we use
prefix_path() instead.

We would need to notice and fail if command line had a nonsense pathspec.
Earlier get_pathspec() returned all the inputs including bad ones, but
the new one issues warnings and removes offending ones from its return
value, so the callers need to be adjusted to notice it.
Additional test scripts were initially from Robin Rosenberg, further fixed.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
The prefix_path() function called from get_pathspec() is
responsible for translating list of user-supplied pathspecs to
list of pathspecs that is relative to the root of the work
tree. When working inside a subdirectory, the user-supplied
pathspecs are taken to be relative to the current subdirectory.
Among special path components in pathspecs, we used to accept
and interpret only "." ("the directory", meaning a no-op) and
".." ("up one level") at the beginning. Everything else was
passed through as-is.
For example, if you are in Documentation/ directory of the
project, you can name Documentation/howto/maintain-git.txt as:
howto/maintain-git.txt
../Documentation/howto/maitain-git.txt
../././Documentation/howto/maitain-git.txt
but not as:
howto/./maintain-git.txt
$(pwd)/howto/maintain-git.txt
This patch updates prefix_path() in several ways:
- If the pathspec is not absolute, prefix (i.e. the current
subdirectory relative to the root of the work tree, with
terminating slash, if not empty) and the pathspec is
concatenated first and used in the next step. Otherwise,
that absolute pathspec is used in the next step.
- Then special path components "." (no-op) and ".." (up one
level) are interpreted to simplify the path. It is an error
to have too many ".." to cause the intermediate result to
step outside of the input to this step.
- If the original pathspec was not absolute, the result from
the previous step is the resulting "sanitized" pathspec.
Otherwise, the result from the previous step is still
absolute, and it is an error if it does not begin with the
directory that corresponds to the root of the work tree. The
directory is stripped away from the result and is returned.
- In any case, the resulting pathspec in the array
get_pathspec() returns omit the ones that caused errors.
With this patch, the last two examples also behave as expected.

This new error mode allows a line to have a carriage return at the

Some people like to keep CRLF line ending recorded in the repository,

When you have more than one patch series, an earlier one of which
tries to introduce whitespace breakages and a later one of which
has such a new line in its context, "git-apply --whitespace=fix"
will apply and fix the whitespace breakages in the earlier one,
making the resulting file not to match the context of the later
patch.
A short demonstration is in the new test, t4125.
For example, suppose the first patch is:
diff a/hello.txt b/hello.txt
--- a/hello.txt
+++ b/hello.txt
@@ -20,3 +20,3 @@
Hello world.$
-How Are you$
-Today?$
+How are you $
+today? $
to fix broken case in the string, but it introduces unwanted
trailing whitespaces to the result (pretend you are looking at
"cat -e" output of the patch --- '$' signs are not in the patch
but are shown to make the EOL stand out). And the second patch
is to change the wording of the greeting further:
diff a/hello.txt b/hello.txt
--- a/hello.txt
+++ b/hello.txt
@@ -18,5 +18,5 @@
Greetings $
-Hello world.$
+Hello, everybody. $
How are you $
-today? $
+these days? $
If you apply the first one with --whitespace=fix, you will get
this as the result:
Hello world.$
How are you$
today?$
and this does not match the preimage of the second patch, which
demands extra whitespace after "How are you" and "today?".
This series is about teaching "git apply --whitespace=fix" to
cope with this situation better. If the patch does not apply,
it rewrites the second patch like this and retries:
diff a/hello.txt b/hello.txt
--- a/hello.txt
+++ b/hello.txt
@@ -18,5 +18,5 @@
Greetings$
-Hello world.$
+Hello, everybody.$

This is done by rewriting the preimage lines in the hunk
(i.e. the lines that begin with ' ' or '-'), using the same
whitespace fixing rules as it is using to apply the patches, so
that it can notice what it did to the previous ones in the
series.
A careful reader may notice that the first patch in the example
did not touch the "Greetings" line, so the trailing whitespace
that is in the original preimage of the second patch is not from
the series. Is rewriting this context line a problem?
If you think about it, you will realize that the reason for the
difference is because the submitter's tree was based on an
earlier version of the file that had whitespaces wrong on that
"Greetings" line, and the change that introduced the "Greetings"
line was added independently of this two-patch series to our
tree already with an earlier "git apply --whitespace=fix".
So it may appear this logic is rewriting too much, it is not
so. It is just rewriting what we would have rewritten in the
past.

We had two pointer variables pointing to the same buffer and an
integer variable used to index into its tail part that was
active (old, oldlines and oldsize for the preimage, and their
'new' counterparts for the postimage).
To help readability, use 'oldlines' as the allocated pointer,
and use 'old' as the pointer to the tail that advances while the
code builds up the contents in the buffer. The size 'oldsize'
can be computed as (old-oldines).

This updates the way preimage and postimage in a patch hunk is
parsed and prepared for applying. By looking at image->line[n].flag,
the code can tell if it is a common context line that is the
same between the preimage and the postimage.
This matters when we actually start applying a patch with
contexts that have whitespace breakages that have already been
fixed in the target file.
Wnen the caller knows the hunk needs to match at the beginning
or at the end, there is no point starting from the line number
that is found in the patch and trying match with increasing
offset. The logic to find matching lines was made more line
oriented with the previous patch and this optimization is now
trivial.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
This changes the way git-apply internally works to be more line
oriented. The logic to find where the patch applies with offset
used to count line numbers by always counting LF from the
beginning of the buffer, but it is simplified because we count
the line length of the target file and the preimage snippet
upfront now.
The ultimate motivation is to allow applying patches
whose preimage context has whitespace corruption that has
already been corrected in the local copy. For that purpose, we
introduce a table of line-hash that allows us to match lines
that differ only in whitespaces.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
This moves the logic to force match at the beginning and/or at
the end of the buffer to the actual function that finds the
match from its caller. This is a necessary preparation for the
next step to allow matching disregarding certain differences,
such as whitespace changes.
We probably could optimize this even more by taking advantage of
the fact that match_beginning and match_end forces the match to
be at an exact location (anchored at the beginning and/or the
end), but that's for another commit.

I was able to solve this problem with this patch, which adds a XSL file
used specifically for DOCBOOK_XSL_172=YesPlease and where dots and
backslashes are escaped properly so they won't be substituted to the
wrong thing further down the "DocBook XSL pipeline". Doing the escaping
