Subject: [PATCH v5 06/15] git-p4: remove p4_write_pipe() and write_pipe() return values
Date: Sat, 07 Dec 2019 17:47:34 +0000	[thread overview]
Message-ID: <e28fe095b41753ecf57c21984913bc2a26f7aa53.1575740863.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.463.v5.git.1575740863.gitgitgadget@gmail.com>

From: Ben Keene <seraphire@gmail.com>

The git-p4 functions write_pipe() and p4_write_pipe() originally
return the number of bytes returned from the system call. However,
this is a misleading value when this function is run by Python 3.

Modify the functions write_pipe() and p4_write_pipe() to remove the
return value.  The return value for both functions is the number of
bytes, but the meaning is lost under python3 since the count does not
match the number of characters that may have been encoded.
Additionally, the return value was never used, so this is removed to
avoid future ambiguity.
