In the course of recent refactorings I noticed a couple of cases where we were doing old-fashioned preallocation of a char array with some conservative maximum size, then writing into it via *p++ or similar and hoping we got the calculation right. Now we have strbuf and dupcat, so we shouldn't ever have to do that. Fixed as many cases as I could find by searching for allocations of the form 'snewn(foo, char)'. Particularly worth a mention was the Windows GSSAPI setup code, which was directly using the Win32 Registry API, and looks much more legible using the windows/utils/registry.c wrappers. (But that was why I had to enhance them in the previous commit so as to be able to open registry keys read-only: without that, the open operation would actually fail on this key, which is not user-writable.) Also unix/askpass.c, which was doing a careful reallocation of its buffer to avoid secrets being left behind in the vacated memory - which is now just a matter of ensuring we called strbuf_new_nm(). |
