Update since v14:

 * Add more testcases for relative_path. See patch 01/16.

 * Refactor: change arguments name for relative_path (in path.c),
   i.e. abc -> in, base -> prefix. This is because the first
   argument is not restricted to absolute path any more.
   See patch 02/16.

 * Move git-ls-files fix from patch 05/16 to patch 03/16.
   See patch 03/16.

 * Remove NO_MINGW and related functions from t0060 script.
   See patch 16/16.

Jiang Xin (16):
  test: add test cases for relative_path
  path.c: refactor relative_path(), not only strip prefix
  quote.c: substitute path_relative with relative_path
  Refactor quote_path_relative, remove unused params
  Refactor write_name_quoted_relative, remove unused params
  git-clean: refactor git-clean into two phases
  git-clean: add support for -i/--interactive
  git-clean: show items of del_list in columns
  git-clean: add colors to interactive git-clean
  git-clean: use a git-add-interactive compatible UI
  git-clean: add filter by pattern interactive action
  git-clean: add select by numbers interactive action
  git-clean: add ask each interactive action
  git-clean: add documentation for interactive git-clean
  test: add t7301 for git-clean--interactive
  test: run testcases with POSIX absolute paths on Windows

Add subcommand "relative_path" in test-path-utils, and add test cases
in t0060.

Johannes tested this commit on Windows, and found that some relative_path
tests should be skipped on Windows. This is because the bash on Windows
rewrites arguments of regular Windows programs, such as git and the
test helpers, if the arguments look like absolute POSIX paths. As a
consequence, the actual tests performed are not what the tests scripts
expect.

The tests that need *not* be skipped are those where the two paths passed
to 'test-path-utils relative_path' have the same prefix and the result is
expected to be a relative path. This is because the rewriting changes
"/a/b" to "D:/Src/MSysGit/a/b", and when both inputs are extended the same
way, this just cancels out in the relative path computation.

Original design of relative_path() is simple, just strip the prefix
(*base) from the absolute path (*abs). In most cases, we need a real
relative path, such as: ../foo, ../../bar. That's why there is another
reimplementation (path_relative()) in quote.c.

Borrowed some codes from path_relative() in quote.c to refactor
relative_path() in path.c, so that it could return real relative path,
and user can reuse this function without reimplement his/her own.
The function path_relative() in quote.c will be substituted, and I
would use the new relative_path() function when implement the
interactive git-clean later.

Different results for relative_path() before and after this refactor:

    abs path  base path  relative (original)  relative (refactor)

    (null)    /a/b       (segfault)           ./

You may notice that return value "." has been changed to "./".
It is because:

 * Function quote_path_relative() in quote.c will show the relative
   path as "./" if abs(in) and base(prefix) are the same.

 * Function relative_path() is called only once (in setup.c), and
   it will be OK for the return value as "./" instead of ".".

Substitute the function path_relative in quote.c with the function
relative_path. Function relative_path can be treated as an enhanced
and robust version of path_relative.

Outputs of path_relative and it's replacement (relative_path) are the
same for the following cases:

    path      prefix     output of path_relative  output of relative_path
    ========  =========  =======================  =======================
    /a/b/c/   /a/b/      c/                       c/
    /a/b/c    /a/b/      c                        c
    /a/       /a/b/      ../                      ../
    /         /a/b/      ../../                   ../../
    /a/c      /a/b/      ../c                     ../c
    /x/y      /a/b/      ../../x/y                ../../x/y
    a/b/c/    a/b/       c/                       c/
    a/        a/b/       ../                      ../
    x/y       a/b/      ../../x/y                 ../../x/y
    /a/b      (empty)    /a/b                     /a/b
    /a/b      (null)     /a/b                     /a/b
    a/b       (empty)    a/b                      a/b
    a/b       (null)     a/b                      a/b

But if both of the path and the prefix are the same, or the returned
relative path should be the current directory, the outputs of both
functions are different. Function relative_path returns "./", while
function path_relative returns empty string.

    path      prefix     output of path_relative  output of relative_path
    ========  =========  =======================  =======================
    /a/b/     /a/b/      (empty)                  ./
    a/b/      a/b/       (empty)                  ./
    (empty)   (null)     (empty)                  ./
    (empty)   (empty)    (empty)                  ./

But not panic, the callers of path_relative can handle such cases, or
never encounter this issue at all. E.g.

 * In function quote_path_relative, if the output of path_relative is
   empty, append "./" to it, like:

       if (!out->len)
           strbuf_addstr(out, "./");

 * Another caller is write_name_quoted_relative, which is only used by
   builtin/ls-files.c. git-ls-files only show files, so path of files
   will never be identical with the prefix of a directory.

The following differences show that path_relative can not handle
extra slashes properly.

    path      prefix     output of path_relative  output of relative_path
    ========  =========  =======================  =======================
    /a//b//c/ //a/b//    ../../../../a//b//c/     c/
    a/b//c    a//b       ../b//c                  c

And if prefix has no trailing slash, path_relative can not work properly
either. But since prefix always has a trailing slash, so it's not a
problem.

    path      prefix     output of path_relative  output of relative_path
    ========  =========  =======================  =======================
    /a/b/c/   /a/b       b/c/                     c/
    /a/b      /a/b       b                        ./
    /a/b/     /a/b       b/                       ./
    /a        /a/b/      ../../a                  ../
    a/b/c/    a/b        b/c/                     c/
    a/b/      a/b        b/                       ./
    a         a/b        ../a                     ../
    x/y       a/b/       ../x/y                   ../../x/y
    a/c       a/b        c                        ../c
    /a/       /a/b       (empty)                  ../

After substitute path_relative() in quote.c with relative_path() from
path.c, parameters (such as len and prefix_len) are obsolete in function
quote_path_relative(). Remove unused parameters and change the order of
parameters for quote_path_relative() function.

After substitute path_relative() in quote.c with relative_path() from
path.c, parameters (such as len and prefix_len) are obsolete in function
write_name_quoted_relative(). Remove unused parameters from
write_name_quoted_relative() and related functions.

Before introducing interactive git-clean, refactor git-clean operations
into two phases:

 * hold cleaning items in del_list,
 * and remove them in a separate loop at the end.

We will introduce interactive git-clean between the two phases. The
interactive git-clean will show what would be done and must confirm
before do real cleaning.

Show what would be done and the user must confirm before actually
cleaning.

    Would remove ...
    Would remove ...
    Would remove ...

    Remove [y/n]?

Press "y" to start cleaning, and press "n" if you want to abort.

When there are lots of items to be cleaned, it is hard to see them all
in one screen. Show them in columns will solve this problem.

From: Jiang Xin @ 2013-06-25 15:53 UTC (permalink / raw)
  To: Junio C Hamano, Johannes Sixt; +Cc: Git List, Jiang Xin

Rewrite menu using a new method `list_and_choose`, which is borrowed
from `git-add--interactive.perl`. We will use this framework to add
new actions for interactive git-clean later.

Please NOTE:

 * Method `list_and_choose` return an array of integers, and
 * it is up to you to free the allocated memory of the array.
 * The array ends with EOF.
 * If user pressed CTRL-D (i.e. EOF), no selection returned.

Add a new action for interactive git-clean: filter by pattern. When the
user chooses this action, user can input space-separated patterns (the
same syntax as gitignore), and each clean candidate that matches with
one of the patterns will be excluded from cleaning. When the user feels
it's OK, presses ENTER and backs to the confirmation dialog.

Draw a multiple choice menu using `list_and_choose` to select items
to be deleted by numbers.

User can input:

 *  1,5-7 : select 1,5,6,7 items to be deleted
 *  *     : select all items to be deleted
 *  -*    : unselect all, nothing will be deleted
 *        : (empty) finish selecting, and return back to main menu

Add a new action for interactive git-clean: ask each. It's just like
the "rm -i" command, that the user must confirm one by one for each
file or directory to be cleaned.

+Interactive mode
+----------------
+When the command enters the interactive mode, it shows the
+files and directories to be cleaned, and goes into its
+interactive command loop.
+
+The command loop shows the list of subcommands available, and
+gives a prompt "What now> ".  In general, when the prompt ends
+with a single '>', you can pick only one of the choices given
+and type return, like this:
+
+------------
+    *** Commands ***
+        1: clean                2: filter by pattern    3: select by numbers
+        4: ask each             5: quit                 6: help
+    What now> 1
+------------
+
+You also could say `c` or `clean` above as long as the choice is unique.
+
+The main command loop has 6 subcommands.
+
+clean::
+
+   Start cleaning files and directories, and then quit.
+
+filter by pattern::
+
+   This shows the files and directories to be deleted and issues an
+   "Input ignore patterns>>" prompt. You can input space-seperated
+   patterns to exclude files and directories from deletion.
+   E.g. "*.c *.h" will excludes files end with ".c" and ".h" from
+   deletion. When you are satisfied with the filtered result, press
+   ENTER (empty) back to the main menu.
+
+select by numbers::
+
+   This shows the files and directories to be deleted and issues an
+   "Select items to delete>>" prompt. When the prompt ends with double
+   '>>' like this, you can make more than one selection, concatenated
+   with whitespace or comma.  Also you can say ranges.  E.g. "2-5 7,9"
+   to choose 2,3,4,5,7,9 from the list.  If the second number in a
+   range is omitted, all remaining patches are taken.  E.g. "7-" to
+   choose 7,8,9 from the list.  You can say '*' to choose everything.
+   Also when you are satisfied with the filtered result, press ENTER
+   (empty) back to the main menu.
+
+ask each::
+
+  This will start to clean, and you must confirm one by one in order
+  to delete items. Please note that this action is not as efficient
+  as the above two actions.
+
+quit::
+
+  This lets you quit without do cleaning.
+
+help::
+
+  Show brief usage of interactive git-clean.

Some test cases are skipped on Windows by marking with POSIX prereq.
This is because arguments look like absolute paths (such as /a/b)
for regular Windows programs (*.exe executables, no bash scripts)
are changed to Windows paths (like C:/msysgit/a/b).

There is no cygpath nor equivalent on msysGit, but it is easy to
write one. New subcommand "mingw_path" is added in test-path-utils,
so that we can get the expected absolute paths on Windows. E.g.

    COMMAND LINE                        Linux output  Windows output
    ==================================  ============  ===============
    test-path-utils mingw_path /        /             C:/msysgit
    test-path-utils mingw_path /a/b/    /a/b/         C:/msysgit/a/b/

With this utility, most skipped test cases in t0060 can be turned on
to be tested correctly on Windows.

Nicely explained.

I'd tweak this function and write_naem_quoted_relative(), and
explain the reason for doing so in the log message.  Please check
what I'll push out on 'pu' later today.

Subject: [PATCH] fix write_name() and write_name_quoted_relative() signature

The write_name_quoted_relative() function used to accept its two
parameters as counted strings.  Since it now uses relative_path(),
which requires both input strings to be NUL-terminated, the API of
this function need to be audited carefully.

Luckily, the only one caller is write_name() in builtin/ls-files.c,
and it in turn has only three callers.  They pass the string to be
made relative at this function and all of these strings happen to be
NUL terminated.  We can safely lose "len" parameter of write_name(),
and write_name_quoted_relative() can safely lose the length of its
name parameter as well.

The "prefix_len" parameter of write_name_quoted_relative() is either
0 (when "ls-files --full-name" is used), or the length of the prefix
string (i.e. the path to the current subdirectory).  By checking the
"--full-name" case in the caller, i.e. write_name(), we can make
write_name_quoted_relative() not to require the prefix as a counted
string.

I somehow lost track, but does the above list of sign-offs reflect
the origins of the changes contained in this patch, or is the second
one meant to be helped-by or something (if so, I can easily amend
locally without a need for rerolling)?

> +relative_path /		/a/b/		/	POSIX

(mental note, not a complaint): These are notable, as some may
expect to see "..", "../.."  and "../c" for these cases, but the
rule is "ignore base and return it if it is absolute", so they are
understandable.

> +relative_path a		a/b		a	# TODO: should be: ..
> +relative_path x/y	a/b		x/y	# TODO: should be: ../../x/y

(mental note): OK.  Let's see how they evolve in later patches.

Thanks.

These i++/j++ are not checked for lengths of strings, but it is OK
because is_dir_sep() will never return true for NUL.

(mental note) *_off keeps track of the last directory separator of
the common part, i.e. where the difference begins.

So shouldn't this be "i == prefix_len"?

Again, "j == in_len", isn't it?  Or can i and j overrun in_len and
prefix_len?

(mental note) Now in points at the part after stripping common

(mental note) it turns out that "in" covered the entire prefix, so
there is no need for "../" in this case.

(mental note) otherwise count '/' in the remainder of the prefix and
prepend as many "../" as necessary.

> +	if (!is_dir_sep(prefix[prefix_len - 1]))

(mental note) ... and one more?  E.g. for prefix="/a/b/c" in="/a/x",
we stripped the common "/a/" and the above loop started counting
from 'b' in the prefix, which counted one slash between b and c, but
we need to go two levels up.  If prefix were "/a/b/c/", we would
already have counted the slash after c, so we do not need to do so.

OK.

OK.  I'll amend the log message a bit to say that we verified that
this conversion is safe.

You seem to be using unusually short abbrev length.

Please don't, at least in format-patch output.

"ebb8" may be unique within your repository, but may not be unique
in repositories of other people who attempt to apply your patches.

Offtopic.  Fixing this, without forcing you to use the default
abbrev length everywhere, _might_ require a bit of changes to the
configuration mechanism, or "git format-patch", or both.  I've also
seen in some other thread that --numstat was used in addition to the
usual --stat, which should not be added to format-patch output only
because the user configured it for other "diff/log" uses, which may
also need to be fixed in the same way.

People may have comments and improvements on the actual
"interactive" UI part, but I think the earlier parts up to "into two
phases" is ready for 'next'.  Let's queue them and have them
advance.

Sorry, my English. I should say: Johannes helped to test these test cases on

Johannes offered a nice patch based on the last one of this
patch series. I move his patch right after the first patch
(patch 01: test: add test cases for relative_path). But I think
as a cooking topic, it should not has a commit to fix another.
So I squash Johannes' commit to the previous commit, and
add his signed-off-by.

Thank you for your notice. I find that I have a setting: core.abbrev=4,
which overrides the default. Maybe I set it two years ago, when I wrote
my book on Git in Chinese.

Yes, better write as ==. But both will pass the test cases.
Since this commit has been merged to next, so let it be?
