From 8f309aeb8225a9c26f20c0dbc031f1ea8df75d49 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 13 Jan 2016 15:31:17 -0800 Subject: [PATCH] strbuf: introduce strbuf_getline_{lf,nul}() The strbuf_getline() interface allows a byte other than LF or NUL as the line terminator, but this is only because I wrote these codepaths anticipating that there might be a value other than NUL and LF that could be useful when I introduced line_termination long time ago. No useful caller that uses other value has emerged. By now, it is clear that the interface is overly broad without a good reason. Many codepaths have hardcoded preference to read either LF terminated or NUL terminated records from their input, and then call strbuf_getline() with LF or NUL as the third parameter. This step introduces two thin wrappers around strbuf_getline(), namely, strbuf_getline_lf() and strbuf_getline_nul(), and mechanically rewrites these call sites to call either one of them. The changes contained in this patch are: * introduction of these two functions in strbuf.[ch] * mechanical conversion of all callers to strbuf_getline() with either '\n' or '\0' as the third parameter to instead call the respective thin wrapper. After this step, output from "git grep 'strbuf_getline('" would become a lot smaller. An interim goal of this series is to make this an empty set, so that we can have strbuf_getline_crlf() take over the shorter name strbuf_getline().
