From cc44c7655fe2dd0cfb46e841156634fe622df397 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 20 Feb 2007 01:53:29 -0800 Subject: Mechanical conversion to use prefixcmp() This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) { s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|; } if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) { s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|; } and running: $ git grep -l strncmp -- '*.c' | xargs perl px.perl Signed-off-by: Junio C Hamano --- builtin-show-ref.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'builtin-show-ref.c') diff --git a/builtin-show-ref.c b/builtin-show-ref.c index 853f13f6ae..ae0edddac1 100644 --- a/builtin-show-ref.c +++ b/builtin-show-ref.c @@ -28,8 +28,8 @@ static int show_ref(const char *refname, const unsigned char *sha1, int flag, vo if (tags_only || heads_only) { int match; - match = heads_only && !strncmp(refname, "refs/heads/", 11); - match |= tags_only && !strncmp(refname, "refs/tags/", 10); + match = heads_only && !prefixcmp(refname, "refs/heads/"); + match |= tags_only && !prefixcmp(refname, "refs/tags/"); if (!match) return 0; } @@ -178,8 +178,8 @@ int cmd_show_ref(int argc, const char **argv, const char *prefix) hash_only = 1; continue; } - if (!strncmp(arg, "--hash=", 7) || - (!strncmp(arg, "--abbrev", 8) && + if (!prefixcmp(arg, "--hash=") || + (!prefixcmp(arg, "--abbrev") && (arg[8] == '=' || arg[8] == '\0'))) { if (arg[2] != 'h' && !arg[8]) /* --abbrev only */ @@ -215,7 +215,7 @@ int cmd_show_ref(int argc, const char **argv, const char *prefix) } if (!strcmp(arg, "--exclude-existing")) return exclude_existing(NULL); - if (!strncmp(arg, "--exclude-existing=", 19)) + if (!prefixcmp(arg, "--exclude-existing=")) return exclude_existing(arg + 19); usage(show_ref_usage); } @@ -224,7 +224,7 @@ int cmd_show_ref(int argc, const char **argv, const char *prefix) unsigned char sha1[20]; while (*pattern) { - if (!strncmp(*pattern, "refs/", 5) && + if (!prefixcmp(*pattern, "refs/") && resolve_ref(*pattern, sha1, 1, NULL)) { if (!quiet) show_one(*pattern, sha1); -- cgit v1.2.3
