From b66d2989e45605cf927fd0f2144696d320e08180 Mon Sep 17 00:00:00 2001 From: Roland Kammerer Date: Fri, 15 Jun 2018 16:16:45 +0200 Subject: [PATCH] build: check for strlcpy() Check for stlcpy() and if found, disable the internal compat code. This does not fix all cases, as we would also have to check for libbsd and link with "-lbsd". Still, this helps Alpine, as their favorite libc (musl) implements strlcpy(). --- configure.ac | 2 +- rsync.c | 2 ++ 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/configure.ac b/configure.ac index 741010f..f3ebff7 100644 --- a/configure.ac +++ b/configure.ac @@ -43,7 +43,7 @@ AM_CONDITIONAL([HAVE_PDFLATEX], test -n "$PDFLATEX") dnl inspired by rsync's configure.ac -AC_CHECK_FUNCS(fchmod setmode open64 mkstemp64) +AC_CHECK_FUNCS(fchmod setmode open64 mkstemp64 strlcpy) AC_CACHE_CHECK([for secure mkstemp],csync_cv_HAVE_SECURE_MKSTEMP,[ AC_TRY_RUN([#include #include diff --git a/rsync.c b/rsync.c index 3eb6b3e..667a227 100644 --- a/rsync.c +++ b/rsync.c @@ -49,6 +49,7 @@ * * @return index of the terminating byte. **/ +#ifndef HAVE_STRLCPY static size_t strlcpy(char *d, const char *s, size_t bufsize) { size_t len = strlen(s); @@ -61,6 +62,7 @@ static size_t strlcpy(char *d, const char *s, size_t bufsize) } return ret; } +#endif /* splits filepath at the last '/', if any, like so: * dirname basename filepath
