Fraser Adams resolved PROTON-774.
---------------------------------
Resolution: Fixed
> Fix warnings in log.c and url.c and re-enable -Werror
> -----------------------------------------------------
>
> Key: PROTON-774
> URL: https://issues.apache.org/jira/browse/PROTON-774
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Reporter: Fraser Adams
> Priority: Trivial
>
> The files log.c and url.c generate warnings when compiled with
> CLang/emscripten this prevents -Werror being used.
> The warnings were:
> [ 56%] Building C object
> proton-c/bindings/javascript/CMakeFiles/qpid-proton-bitcode.dir/__/__/src/log.c.o
> /home/fadams/qpid/git/qpid-proton/proton-c/src/log.c:38:13: warning:
> explicitly
> assigning a variable of type 'bool' to itself [-Wself-assign]
> enabled = enabled;
> and
> [ 58%] Building C object
> proton-c/bindings/javascript/CMakeFiles/qpid-proton-bitcode.dir/__/__/src/url.c.o
> /home/fadams/qpid/git/qpid-proton/proton-c/src/url.c:133:19: warning: unused
> function 'len' [-Wunused-function]
> static inline int len(const char *str) { return str ? strlen(str) : 0; }
> The trivial fixes were to remove the spurious function in url.c and rename
> the formal parameter to pn_log_enable in log.c
