Description: When compiling the C++ bridge code, you will see several warnings about the use of uninitialized variables. Linux / OSX ../src/config.cc:376:2: warning: variable 'from_tx' is uninitialized when used here [-Wuninitialized] *from_tx = Nan::ObjectWrap::Unwrap(info[0]->ToObject())->GetValue(); ^~~~~~~ ../src/config.cc:375:29: note: initialize the variable 'from_tx' to silence this warning git_transaction ** from_tx; ^ = nullptr Windows nodegit\src\tree.cc(588): warning C4700: uninitialized local variable 'from_dest' used [nodegit\build\nodegit.vcxproj] nodegit\src\rebase.cc(486): warning C4700: uninitialized local variable 'from_index' used [nodegit\build\nodegit.vcxproj] nodegit\src\libgit2.cc(164): warning C4700: uninitialized local variable 'from_major' used [nodegit\build\nodegit.vcxproj] nodegit\src\libgit2.cc(168): warning C4700: uninitialized local variable 'from_minor' used [nodegit\build\nodegit.vcxproj] nodegit\src\libgit2.cc(172): warning C4700: uninitialized local variable 'from_rev' used [nodegit\build\nodegit.vcxproj] nodegit\src\config.cc(362): warning C4700: uninitialized local variable 'from_tx' used [nodegit\build\nodegit.vcxproj] nodegit\src\index.cc(1511): warning C4700: uninitialized local variable 'from_at_pos' used [nodegit\build\nodegit.vcxproj] nodegit\src\tree_entry.cc(219): warning C4700: uninitialized local variable 'from_object_out' used [nodegit\build\nodegit.vcxproj] nodegit\src\commit.cc(2364): warning C4700: uninitialized local variable 'from_tree_out' used [nodegit\build\nodegit.vcxproj] nodegit\src\tag.cc(1767): warning C4700: uninitialized local variable 'from_tag_target_out' used [nodegit\build\nodegit.vcxproj] nodegit\src\status.cc(665): warning C4700: uninitialized local variable 'from_ignored' used [nodegit\build\nodegit.vcxproj] nodegit\src\revparse.cc(67): warning C4700: uninitialized local variable 'from_object_out' used [nodegit\build\nodegit.vcxproj] nodegit\src\revparse.cc(71): warning C4700: uninitialized local variable 'from_reference_out' used [nodegit\build\nodegit.vcxproj] The warnings above can easily be fixed by initializing these pointer variables to NULL. We should strive to have as few warnings as possible in the code (if not zero) to make the compilation logs more readable by improving the signal to noise ratio wherever possible.
