c - warning for not using free() malloc -

are there safeguards built gcc check memory leaks? if how can utilize them? when compile "gcc -wall -o run run.c", compiler not seem care if allocated heap-space beingness freed @ end of code. not find simple fixes on google.

thanks much time.

edit: google searches did point valgrind among other tools. curious why compiler cant deal issue. newbie, seemed simple plenty task check if every "malloc" has "free" associated it.

there 2 ways analyze code problems - static analysis , run-time analysis. static analysis reads code - compilers well. run-time analysis code problems happens when code linked against set of libraries see code runs under surveillance. finding memory leaks hard static analysis not run-time analysis package.

other run-time analyses things code coverage - parts of code run? gcov this, valgrind , electrical fence memory problems leaks.

so, no, there no compiler safeguards testing memory leaks.

python - How to add an model instance to a django queryset? - it seems django queryset behaves somehow python list. but doesn't back upwards list's .append() method know. what want like: from my_django_app.models import mymodel queryset = mymodel.objects.none() queryset.append(mymodel.objects.first()) ## no list's .append() method! is there way add together model instance existing queryset? no. queryset representation of query - hence name - not arbitrary collection of instances. if need actual queryset rather list, seek accumulating ids of objects need , getting objects via __in query: list_of_ids = [] list_of_ids.append(my_id) ... queryset = mymodel.objects.filter(id__in=list_of_ids) this isn't efficient, though. python django
