Subject: [PATCH 3/3] sequencer: reencode to utf-8 before arrange rebase's todo list
Date: Thu, 31 Oct 2019 16:26:18 +0700 [thread overview]
Message-ID: <20191031092618.29073-4-congdanhqx@gmail.com> (raw)
In-Reply-To: <20191031092618.29073-1-congdanhqx@gmail.com>
On musl libc, ISO-2022-JP encoder is too eager to switch back to
1 byte encoding, musl's iconv always switch back after every combining
character. Comparing glibc and musl's output for this command
$ sed q t/t3900/ISO-2022-JP.txt| iconv -f ISO-2022-JP -t utf-8 |
iconv -f utf-8 -t ISO-2022-JP | xxd
glibc:
00000000: 1b24 4224 4f24 6c24 5224 5b24 551b 2842 .$B$O$l$R$[$U.(B
00000010: 0a .
musl:
00000000: 1b24 4224 4f1b 2842 1b24 4224 6c1b 2842 .$B$O.(B.$B$l.(B
00000010: 1b24 4224 521b 2842 1b24 4224 5b1b 2842 .$B$R.(B.$B$[.(B
00000020: 1b24 4224 551b 2842 0a .$B$U.(B.
Although musl iconv's output isn't optimal, it's still correct.
From commit 7d509878b8, ("pretty.c: format string with truncate respects
logOutputEncoding", 2014-05-21), we're encoding the message to utf-8
first, then format it and convert the message to the actual output
encoding on git commit --squash.
Thus, t3900 is failing on Linux with musl libc.
Reencode to utf-8 before arranging rebase's todo list.

Notes:
The todo list shown to user has already been reencoded by sequencer_make_script,
without this patch it looks like this:
