If ref is valid, 'n < N' was probably meant here.

This might be an indication that the font used is rendering the
symbol as an emoji. Most scissors in emoji fonts are vertical:

[PATCH v2 2/2] mailinfo: support Unicode scissors

2019-04-01 Thread Andrei Rybak
Thank you all for review.  Below is the second version of original patch,
addressing comments by Gábor and Peff.

While preparing v2 I found out that U+2702 was already suggested on the list
eight months before cutting at perforation lines was implemented:
https://public-inbox.org/git/200901181656.37813.markus.heidelb...@web.de/T/#m3856d2e5c5f3e1900210b74bf2be8851b92d2271

Subject: [PATCH v2 2/2] mailinfo: support Unicode scissors
Date: Mon, 1 Apr 2019 00:00:00 +

'git am --scissors' allows cutting a patch from an email at a scissors
line.  Such a line should contain perforation, i.e. hyphens, and a
scissors symbol.  Only ASCII graphics scissors '8<' '>8' '%<' '>%' are
recognized by 'git am --scissors' command at the moment.

Unicode character 'BLACK SCISSORS' (U+2702) has been a part of Unicode
since version 1.0.0 [1].  Since then 'BLACK SCISSORS' also became part
of character set Emoji 1.0, published in 2015 [2].  With its adoption as
an emoji, availability of this character on keyboards has increased.

Support UTF-8 encoding of '✂' in function is_scissors_line, for 'git am
--scissors' to be able to cut at Unicode perforation lines in emails.
Note, that Unicode character '✂' is three bytes in UTF-8 encoding and is
spelled out using hexadecimal escape sequence.

[PATCH v2 1/2] mailinfo: use starts_with() for clarity

2019-04-01 Thread Andrei Rybak
Existing checks using memcmp(3) never read past the end of the line,
because all substrings we are interested in are two characters long, and
the outer loop guarantees we have at least one character. So at most we
will look at the NUL.

However, this is too subtle and may lead to bugs in code which copies
this behavior without realizing substring length requirement.  So use
starts_with() instead, which will stop at NUL regardless of the length
of the prefix. Remove extra pair of parentheses while we are here.

With the start of the message being "switching to ..." this part could probably

[PATCH] t4150: remove unused variable

In commit 735285b403 ("am: fix signoff when other trailers are present",
2017-08-08) tests using variable $signoff were rewritten and it is no
longer used, so just remove it from the test setup.

Test description reads "from another branch". However "first", created by
test_commit invocation is a tag. Maybe description should read "from another
ref"? Same applies to other tests which utilize "first".

This would be very useful for people who use MUAs without

Robert, in this setup you might also want (just for convenience)
to sync files "platform1.gitconfig" and "platform2.gitconfig", so
that they are available everywhere for editing and can be copied
into local version of platform-specific.gitconfig at any time.

How about just using unconditional includes?

global.gitconfig (synced across machines):

  [include]
  path = platform-specific.gitconfig

And two version of file named "platform-specific.gitconfig", which
are not synced, and include only code.autocrlf setting.

No. Only when both "$1" and "$2" are empty files will the function above
report "bug in test script". From patch's commit message:

  ... both invocations produce empty 'pack{a,b}.objects' files, and the
  subsequent 'test_cmp' happily finds those two empty files identical.

That's what I meant by "will only catch cases exactly like the bogus
test in t5310".

However ...

... this is indeed a better solution. I written out the cases for
updated test_cmp to straighten out my thinking:

 * both $1 and $2 are empty:
 bogus test:
   needs either fixing generation of both expect and actual
   or switching to test_must_be_empty
   OR
 bogus helper function, as Gábor described above:
   needs to switch to test_cmp_allow_empty
 
 * $1 is non-empty && $2 is empty
   proceeding with test
   test failure from GIT_TEST_CMP
 
 * $1 is empty && $2 is non-empty
   bogus test - needs either switching to test_must_be_empty
   (and after that test_must_be_empty will report failure)
   or fixing generation of expect (and after that test result
   depends on contents).
 
 * both $1 and $2 are non-empty
   proceeding with test
   result depends on contents

I came up with two solutions for this issue:

  1. Check both files at the same time (combination with Gábor's
 function):

test_cmp () {
if test "$1" != - &&
   test "$2" != - &&
   ! test -s "$1" && 
   ! test -s "$2"
then
error "bug in test script: using test_cmp to check 
empty file; use test_must_be_empty instead"
fi
test_cmp_allow_empty "$@"
}

 This will still be reporting to the developer clearly, but
 will only catch cases exactly like the bogus test in t5310.

  2. Enable this check via variable, smth like EMPTY_CMP_LINT=1

I've only had time to look into this from t0001 up to t0008-ignores.sh, where
test_check_ignore does this. If these helper functions need to allow comparing
empty files -- how about adding special variation of cmp functions for cases
like this: test_cmp_allow_empty and test_i18ncmp_allow_empty?

I think it would be a good trade-off to allow these helper functions to skip
checking emptiness of arguments for test_cmp. Such patch will require only
s/test_cmp/&_allow_empty/ for these helper functions and it will help catch
cases as bogus test in t5310.

I'll try something like the following on the weekend:

test_cmp() {
if test "$1" != - && ! test -s "$1"
then
echo >&4 "error: trying to compare empty file '$1'"
return 1
fi
if test "$2" != - && ! test -s "$2"
then
echo >&4 "error: trying to compare empty file '$2'"
return 1
fi
test_cmp_allow_empty "$@"
}

test_cmp_allow_empty() {
$GIT_TEST_CMP "$@"
}

(I'm not sure about redirections in test lib functions. The two if's would
probably be in a separate function to be re-used by test_i18ncmp.)

Is test_cmp ever used for empty files? Would it make sense for
test_cmp to issue warning when an empty file is being compared?

[PATCH v2] line-log: clarify [a,b) notation for ranges

Applies on top of c0babbe69 (range-set: publish API for re-use by
git-blame -L, 2013-08-06). When applied on the original commit 12da1d1f6
(Implement line-history search (git log -L), 2013-03-28), the conflict
is in removal of "static" from some functions.

Changes since v1:

 - reword commit message a bit
 - sign-off
 - add [a,b) to comment of range_set_append_unsafe

I decided not to remove "_at the end_", as

  /* tack on a _new_ range [a,b) */

seems a bit less readable to me.

[RFC PATCH] line-log: clarify [a,b) notation for ranges

2018-08-07 Thread Andrei Rybak
line-log.[ch] use left-closed, right-open interval logic. Change comment
and debug output to square brackets+parentheses notation to help

Original idea for this change in recent thread about line-log changes:

  https://public-inbox.org/git/9776862d-18b2-43ec-cfeb-829418d4d...@gmail.com/

line-log.c also uses ASCII graphics |---| in some comments, like:

/*
 * a: |---
 * b: --|
 */

But I'm not sure if replacing them with

/*
 * a: [---
 * b: --)
 */

will be helpful.  Another possibility is to update comment for
range_set_append_unsafe to read

  /* tack on a _new_ range [a,b) _at the end_ */
  void range_set_append_unsafe(struct range_set *rs, long a, long b)

[PATCH v3] t4150: fix broken test for am --scissors

2018-08-06 Thread Andrei Rybak
Tests for "git am --[no-]scissors" [1] work in the following way:

 1. Create files with commit messages
 2. Use these files to create expected commits
 3. Generate eml file with patch from expected commits
 4. Create commits using git am with these eml files
 5. Compare these commits with expected

The test for "git am --scissors" is supposed to take an e-mail with a
scissors line and in-body "Subject:" header and demonstrate that the
subject line from the e-mail itself is overridden by the in-body header
and that only text below the scissors line is included in the commit
message of the commit created by the invocation of "git am --scissors".
However, the setup of the test incorrectly uses a commit without the
scissors line and without the in-body header in the commit message,
producing eml file not suitable for testing of "git am --scissors".

This can be checked by intentionally breaking is_scissors_line function
in mailinfo.c, for example, by changing string ">8", which is used by
the test. With such change the test should fail, but does not.

Fix broken test by generating eml file with scissors line and in-body
header "Subject:". Since the two tests for --scissors and --no-scissors
options are there to test cutting or keeping the commit message, update
both tests to change the test file in the same way, which allows us to
generate only one eml file to be passed to git am. To clarify the
intention of the test, give files and tags more explicit names.

How about "expected-for-scissors" and "expected-for-no-scissors"?
Junio, I'll send out v3 with updated tag names, if that's OK.
Also, squash-able patch below.

I don't know line-log.c at all, but here are my comments on the more
abstract range and range_set changes:

As I understand it, this patch attempts to make range_set_append extend
the last range in the range set to include [a,b), if [a,b) "touches" the
last range in rs.

Definition of range from line-log.h reads:

  /* A range [start,end].  Lines are numbered starting at 0, and the
   * ranges include start but exclude end. */
  struct range {
  long start, end;
  };

So the optimization described in commit message should take care of
following case, with zero lines between last range in rs and [a,b):

  rs before : [---) ... [---)
  [a,b) :   [---)
  rs after  : [---) ... [---)
  
It seems that the first condition in range_set_append should be:

if (rs->nr > 0 && rs->ranges[rs->nr-1].end == a) {
// extend the last range to include [a, b)
}

I think that the comments around struct range could be improved by
switching from using "[]", as in the comment from line-log.h quoted
above, and "|---|" as in various comments in line-log.c to "left-closed,
right-open" interval notation like "[start,end)" and "[---)".

>   assert(rs->nr == 0 || rs->ranges[rs->nr-1].end <= a);
>   range_set_append_unsafe(rs, a, b);
>  }

With these consideration in mind the assert should become

assert(rs->nr == 0 || rs->ranges[rs->nr-1].end < a);
  
to cover cases starting from one line between last range in rs and [a,b)

  rs before : [---) ... [---)
  [a,b) :[---)
  rs after  : [---) ... [---)[---)
^
|
this line still not part of the range set.
  


[PATCH v2] t4150: fix broken test for am --scissors

2018-08-04 Thread Andrei Rybak
Tests for "git am --[no-]scissors" [1] work in the following way:

 1. Create files with commit messages
 2. Use these files to create expected commits
 3. Generate eml file with patch from expected commits
 4. Create commits using git am with these eml files
 5. Compare these commits with expected

The test for "git am --scissors" is supposed to take a message with a
scissors line and demonstrate that the subject line from the e-mail
itself is overridden by the in-body "Subject:" header and that only text
below the scissors line is included in the commit message of the commit
created by the invocation of "git am --scissors". However, the setup of
the test incorrectly uses a commit without the scissors line and in-body
"Subject:" header in the commit message, and thus, creates eml file not
suitable for testing of "git am --scissors".

This can be checked by intentionally breaking is_scissors_line function
in mailinfo.c, for example, by changing string ">8", which is used by
the test. With such change the test should fail, but does not.

Fix broken test by generating eml file with scissors line and in-body
header "Subject:". Since the two tests for --scissors and --no-scissors
options are there to test cutting or keeping the commit message, update
both tests to change the test file in the same way, which allows us to
generate only one eml file to be passed to git am. To clarify the
intention of the test, give files and tags more explicit names.

Just swapping eml files wouldn't be enough, because in old tests the
prepared commits touch different files: scissors-file and
no-scissors-file. And since tests are about cutting/keeping commit
message, it doesn't make much sense to keep two eml files which differ
only in contents of their diffs. I'll try to reword the commit message
to also include this bit.

Yes, the adding of "Subject: " prefix is completely overlooked in the
commit message. I'll add explanation in re-send.

I'll double check this and restore the blank line in v2, if the
removal is not needed. IIRC, I removed it by accident and didn't
think too much of it.

Thank you for review.

[RFC] broken test for git am --scissors

2018-08-03 Thread Andrei Rybak
I was tweaking is_scissors_line function in mailinfo.c and tried writing
some tests for it.  And discovered that existing test for git am option
--scissors is broken.  I then confirmed that by intentionally breaking
is_scissors_line, like this:

--- 8< ---
Subject: [PATCH 1/2] mailinfo.c: intentionally break is_scissors_line

It seems that tests for "git am" don't actually test the --scissor
option logic.  Break is_scissors_line function by using bogus symbols to
be able to check the tests.

Note that test suite does not pass with this patch applied.  The
expected failure does not happen.

Here's a proof-of-concept patch for the test, to make it actually fail
when is_scissors_line is broken.  It is the easiest way to do so, that I
could come up with, it is not ready to be applied.  I think the two
tests for --scissors should be rewritten pretty much from scratch, with
more obvious naming of files used.

(I made the changes to files in both tests the same just to be able to
re-use file "no-scissors-patch.eml", it's not relevant to the scissor
line in the commit messages.)

Subject: [PATCH 2/2] t4150-am.sh: fix test for --scissors

Test for option --scissors should check that the eml file with a scissor
line inside will be cut up and only the part under the cut will be
turned into commit.

However, the test for --scissors generates eml file without such line.
Fix the test for --scissors option.

Is -1 an OK initial value for timezone if local_time_tzoffset returns
negative values as well? It looks like it doesn't matter for from functional

[BUG] git cherry-pick does not complain about unknown options

2018-07-09 Thread Andrei Rybak
Hi,

I was trying to cherry pick commits, while simultaneously changing the
author.  Unfortunately, cherry-pick doesn't have the same --author
option as git-commit.  However, instead of complaining about unknown
option:

- when trying to cherry-pick one commit, it reported a BUG
- when trying to cherry-pick several commits, cherry-pick silently
  did nothing

All commits in tests existed in repository:

$ git cherry-pick --author='TEST'  # case 1
error: BUG: expected exactly one commit from walk
fatal: cherry-pick failed
$ echo $?
128
$ git cherry-pick --author='TEST'# case 2
$ echo $?
0
$ git --version
git version 2.18.0.windows.1

I've encountered this issue in Windows version, and  Johannes Schindelin
has confirmed that the issue is also present in Linux version.

Does strbuf out leak on return here?

This text after @@ is usually a function name in a programming language or
some other relevant part of hunk context, to help user navigate the diff more
easily.  What you are getting is the default version of it, as it is just
comparing txt files.  You can read more about it in the documentation of 
gitattributes:

Does that mean that the integration of a series is easier, when there is
a re-send?


Obsolete instruction in SubmittingPatches?

2018-02-28 Thread Andrei Rybak
Hello,

It seems to me that this part of Documentation/SubmittingPatches is
not actual nowadays:

  After the list reached a consensus that it is a good idea to apply the
  patch, re-send it with "To:" set to the maintainer{1} and "cc:" the
  list{2} for inclusion.

>From what I observe in the mailing list, most patches are sent with
"To:" set to mailing list (or re-sent with increasing version) , as per
previous paragraph in the guidelines [1].  Then, after the topic is
reviewed and the [PATCH v] series receives a thumbs up from a
number of people, the maintainer--Junio C Hamano--replies with an email
containing something along the lines of "This change is in good
shape.  Thanks, will queue.", which makes me think that the re-send
is not actually needed.

Is this part of guidelines obsolete, or am I not understanding this
correctly?

[1] "Send your patch with "To:" set to the mailing list, with "cc:"
listing people who are involved in the area you are touching"
