  8505. + needed for actual computation, (package, version, status,
  8506. + essential, conffiles). The assumption is that all other fields
  8507. + can be found in th available file.
  8508. +
  8509. + But, someone proposed the idea to make it possible to
  8510. + reconstruct a .ipk from an installed package, (ie. for beaming
  8511. + from one handheld to another). So, maybe we actually want a few
  8512. + more fields here, (depends, suggests, etc.), so that that would
  8513. + be guaranteed to work even in the absence of more information
  8514. + from the available file.
  8515. +
  8516. + 28-MAR-03: kergoth and I discussed this yesterday. We think
  8517. + the essential info needs to be here for all installed packages
  8518. + because they may not appear in the Packages files on various
  8519. + feeds. Furthermore, one should be able to install from URL or
  8520. + local storage without requiring a Packages file from any feed.

  9369. + distinct. This has been the source of multiple bugs.
  9370. +
  9371. + The 3 state fields could possibly also go into their own struct.
  9372. +
  9373. + All fields which deal with lists of packages, (Depends,
  9374. + Pre-Depends, Provides, Suggests, Recommends, Enhances), should each
  9375. + be handled by a single struct in pkg_t
  9376. +
  9377. + All string fields for which there is a small set of possible
  9378. + values, (section, maintainer, architecture, maybe version?), that
  9379. + are reused among different packages -- for all such packages we
  9380. + should move from "char *"s to some atom datatype to share data
  9381. + storage and use less memory. We might even do reference counting,
  9382. + but probably not since most often we only create new pkg_t structs,
