From: levill_r <levill_r@4aad255d-cdde-0310-9447-f3009e2ae8c0> * src/function_loader.cc (dyn::function_loader_t::cache_type): Use C++ string as keys so as to solve some memory management issues. (dyn::function_loader_t::ruby_load) (dyn::function_loader_t::cxx_load): Adjust. (dyn::ltstr): Remove functor class. git-svn-id: https://svn.lrde.epita.fr/svn/oln/trunk@4669 4aad255d-cdde-0310-9447-f3009e2ae8c0 --- dynamic-use-of-static-c++/ChangeLog | 11 +++++++++++ dynamic-use-of-static-c++/src/function_loader.cc | 20 +++++++++----------- 2 files changed, 20 insertions(+), 11 deletions(-) diff --git a/dynamic-use-of-static-c++/ChangeLog b/dynamic-use-of-static-c++/ChangeLog index 5b9e6e1..9a6d4bc 100644 --- a/dynamic-use-of-static-c++/ChangeLog +++ b/dynamic-use-of-static-c++/ChangeLog @@ -1,5 +1,16 @@ 2009-10-26 Roland Levillain &lt;roland(a)lrde.epita.fr&gt; + Fix the caching system. + + * src/function_loader.cc (dyn::function_loader_t::cache_type): Use + C++ string as keys so as to solve some memory management issues. + (dyn::function_loader_t::ruby_load) + (dyn::function_loader_t::cxx_load): + Adjust. + (dyn::ltstr): Remove functor class. + +2009-10-26 Roland Levillain &lt;roland(a)lrde.epita.fr&gt; + Clean the test repository during general cleaning. * test/Makefile.am (repository_clean): Rename target as... diff --git a/dynamic-use-of-static-c++/src/function_loader.cc b/dynamic-use-of-static-c++/src/function_loader.cc index cc25268..e1b0329 100644 --- a/dynamic-use-of-static-c++/src/function_loader.cc +++ b/dynamic-use-of-static-c++/src/function_loader.cc @@ -49,14 +49,6 @@ namespace dyn { ruby::environment ruby_environment; - struct ltstr - { - bool operator()(const char* s1, const char* s2) const - { - return strcmp(s1, s2) < 0; - } - }; - std::list<std::string> includes_; template <typename Fun> @@ -376,7 +368,7 @@ namespace dyn { std::string prototype = ostr.str(); ruby << "MD5.new(%q{" << prototype.c_str() << "}).to_s" << ruby::eval; - const char* identifier = STR2CSTR(ruby.last_value()); + std::string identifier = STR2CSTR(ruby.last_value()); cache_type::iterator ptr_it = cache.find(identifier); @@ -446,7 +438,7 @@ namespace dyn { // the interface of libmd5. std::string identifier(MD5((unsigned char*)prototype.c_str()).hex_digest()); - cache_type::iterator ptr_it = cache.find(identifier.c_str()); + cache_type::iterator ptr_it = cache.find(identifier); // FIXME: It seems the cache doesn't work at all (we almost // never hit).
