126 be mistaken for pkg_verson_str_alloc(pkg) although they are very
127 distinct. This has been the source of multiple bugs.
129 The 3 state fields could possibly also go into their own struct.
131 All fields which deal with lists of packages, (Depends,
132 Pre-Depends, Provides, Suggests, Recommends, Enhances), should each
133 be handled by a single struct in pkg_t
135 All string fields for which there is a small set of possible
136 values, (section, maintainer, architecture, maybe version?), that
137 are reused among different packages -- for all such packages we
138 should move from "char *"s to some atom datatype to share data
139 storage and use less memory. We might even do reference counting,
140 but probably not since most often we only create new pkg_t structs,
141 we don't often free them. */
