Subject: [PATCH v2 2/8] config: report correct line number upon error
Date: Thu, 8 Jun 2017 21:53:35 +0200 (CEST) [thread overview]
Message-ID: <291e8b643990aee04654b34c6f953387c3c030d4.1496951503.git.johannes.schindelin@gmx.de> (raw)
In-Reply-To: <cover.1496951503.git.johannes.schindelin@gmx.de>
When get_value() parses a key/value pair, it is possible that the line
number is decreased (because the \n has been consumed already) before the
key/value pair is passed to the callback function, to allow for the
correct line to be attributed in case of an error.
However, when git_parse_source() asks get_value() to parse the key/value
pair, the error reporting is performed *after* get_value() returns.
Which means that we have to be careful not to increase the line number
in get_value() after the callback function returned an error.
