 2004-03-17 pigi ( pigi@frumar.it)
         *  Added the implement for Essential in status file. This is needed to avoid the unintentional remove
            of essential packages. In effect the command "ipkg remove ipkg" worked without problems, but then
            it was difficult to reinstall. This fix the bug # 867

         *  Changes to correct the behaviour of verbosity. Now the "0" works, and the "1" is again

 2004-02-29 florian <florian.boor@kernelconcepts.de>
         pkg.c: Pigi and me poked around a little bit and located the cause of
                latest segfault. strncat is not used correctly in pkg_formatted_info
                    and pkg_formatted_field. I added a fix to the only section that
                    triggered the bug and increased a buffer size.
                    BUT: There are many similar bugs remaining!

         * configure.ac: updated to 0.99.115
         * ipkg_cmd.c: segv caught by pigi: buffer freed in loop but used on next iterations.  bug squashed.

         * ipkg_conf.c, ipkg_dest.c: Update status file atomically, keeping
         old copy of status file if cannot update new status file.  Applied
         patch from Jukka Santala for this fix.
         
 2002-03-16  Carl Worth  <cworth@east.isi.edu>
 
         * configure.ac: Incremented version number to 0.99.9-1.
 
         * RELEASE_NOTES: Added release notes for 0.99.9-1.
         
 2002-03-15  Carl Worth  <cworth@east.isi.edu>
 
         * configure.ac: Incremented version number to 0.99.9.
 
         * RELEASE_NOTES: Added release notes for 0.99.9.
 
         * Makefile.am (bin_PROGRAMS): Install update-alternatives as well.
 
         * familiar/rules (binary-arch): Mv all of /bin to /usr/bin
 
         * configure.ac: Incremented version number to 0.99.8.
 
         * RELEASE_NOTES: Added release notes for 0.99.8.
 
         * familiar/rules (binary-arch): Fixed to use "make install-strip"
         rather than "make install" and a strip command.
 
         * ipkg_cmd.c (ipkg_install_cmd): Moved an error message up from
         ipkg_install_by_name, (eventually all error messages should come
         up out of what will become libipkg, (pkg.c, ipkg_install.c, etc.)
         and into ipkg_cmd.c and friends).
         (ipkg_upgrade_pkg): Pushed downgrade check down into
         ipkg_install_by_name so that "ipkg install foo" will do the
         downgrade check.
 
         * ipkg.h: Rename some ipkg_error_t error codes to be more
         consistent.
 
         * ipkg_install.c (resolve_conffiles): Added missing removal of
         backed-up modified conffiles, (which led to bizarre, bogus
         conffile prompting the next time the package was upgraded).
         (user_prefers_old_conffile): Fixed reversed arguments to diff in
         interactive conffiles prompting.
         (ipkg_install_by_name): Fixed "ipkg install foo" to never
         downgrade foo, (just like "ipkg upgrade foo").
 
         * familiar/rules: Added installation of
         /usr/share/doc/ipkg/copyright file. Fixed so that ipkg.conf goes
         to /etc, not /usr/etc, (but still keep binary in /usr/bin not
         /bin). Changed name of installed binary from ipkg-unstable to
         ipkg.
 
         * familiar/control.in (Package): Changed package name from
         ipkg-unstable to ipkg.
 
         * pkg_parse.c (parseVersion): Fixed to ignore whitespace at
         beginning of version string.
         (pkg_parse_raw): Fixed segfault if a package record list ends with
         a package paragraph without a final blank line.
 
         * ipkg_install.c (check_data_file_clashes): Improved wording of
         file clash error message.
 
         * ipkg_download.c (ipkg_download_pkg): Fixed segfault if package
         has no src, (occurs if package had benn installed locally, then
         was removed (but not purged), then tried to reinstall eithout it
         existing in any /usr/lib/ipkg/lists/* file).
 
         * etc/ipkg.conf: Added a default ipkg.conf to the distribution.
 
 2002-03-13  Carl Worth  <cworth@east.isi.edu>
 
         * configure.ac: Incremented version to 0.99.7.
 
         * RELEASE_NOTES: Added release notes for 0.99.7.
 
         * pkg.c (pkg_run_script): Added support to export
         IPKG_OFFLINE_ROOT. This is really a nasty hack as it means scripts
         need to be modified to check IPKG_OFFLINE_ROOT. I'd really prefer
         coming up with a good, reliable chroot system. But for now this
         will let update-alternatives work, (which already does examine
         IPKG_OFFLINE_ROOT).
         (pkg_run_script): Added missing brace.
 
         * ipkg_conf.c (ipkg_conf_init): Reworked significantly to properly
         set up the pkg_dest_list stuff to account for offline_root.
 
         * args.c (args_parse): Added support for -force_defaults in
         addition to -force-defaults, etc. as I kept mistyping these
         somehow.
 
 2002-03-12  Carl Worth  <cworth@east.isi.edu>
 
         * configure.ac: Incremented version to 0.99.6.
 
         * RELEASE_NOTES: Added release notes for 0.99.6.
 
         * ipkg_download.c (ipkg_download): Fixed bug in handling of
         "file://" URLs.
 
         * ipkg.c (main): Fixed to abort if ipkg_conf_init fails.
 
         * ipkg_conf.c (ipkg_conf_init): Fixed to complain if given an
         unknown dest.
 
         * pkg.c (pkg_print_field): Fixed several fields to not print if
         NULL, (Architecture. Maintainer, Size, Filename, Description)
 
         * args.c (args_parse): Fixed bug that was always setting
         force_removal_of_essentail_packages (yikes!).
 
         * configure.ac: Incremented version to 0.99.5.
 
         * RELEASE_NOTES: Added release notes for 0.99.5.
 
         * familiar/rules (binary-arch): Added strip back in in preparation
         of non-unstable release of ipkg.
 
         * str_util.c (str_starts_with): Added convenience function.
 
         * pkg_extract.c (pkg_extract_data_file_names_to_file): Fixed
         filenames in *.list files to be compatible with dpkg and the old
         ipkg, (no prefix of "." for example).
 
         * pkg.c (pkg_run_script): Added export of PKG_ROOT for the benefit
         of maintainer scripts.
 
         * ipkg_remove.c (ipkg_remove_pkg): Complain and abort if user
         attempts to remove an essential package, (also inform them of the
         force option if they insist).
 
         * ipkg_install.c (ipkg_install_pkg): Added message about whether
         installing or upgrading.
 
         * ipkg_download.c (ipkg_download): Added support for "file://"
         URLs, (untested).
         (ipkg_download): Added support for wget proxy options.
 
         * ipkg_conf.c (ipkg_conf_init): Added proxy support to ipkg_conf,
         (http_proxy, ftp_proxy, no_proxy, proxy_user, and proxy_passwd).
 
         * ipkg_cmd.c (ipkg_upgrade_pkg): Moved Upgrading message from
         ipkg_upgrade_cmd to ipkg_install_pkg.
 
         * args.c (args_parse): Added new option
         -force-removal-of-essential-packages, (which is intentionally
         painful to type and not listed in usage. It should not be used
         often).
 
 2002-03-11  Carl Worth  <cworth@east.isi.edu>
 
         * configure.ac: Incremented version to 0.99.3.
 
         * RELEASE_NOTES: Added release notes for 0.99.3.
 
         * pkg_depends.c (pkg_hash_fetch_unsatisfied_dependencies): Fixed
         to avoid infinite loop in the case of a circular dependency.
 
         * configure.ac: Incremented version to 0.99.2.
 
         * RELEASE_NOTES: Added release notes for 0.99.2.
 
         * familiar/rules: Commented out strip, (temporary until this beast
         is deemed more stable).
 
         * xsystem.c (xsystem): Cleaned up error message, (missing
         newline).
 
         * pkg.c (pkg_merge): Made pkg_merge a NOP if oldpkg == newpkg.
         (pkg_print_field): Don't print MD5sum field if NULL.
 
         * ipkg_install.c (satisfy_dependencies_for): Now returns error
         status if one or more of the dependencies fail to install cleanly.
         (unpack_pkg_control_files): Fixed to not tack on a bunch of
         NULL-valued conffiles entries if non-NULL conffiles already
         exist. This fixed the errant prompting for unmodified conffiles
         during -force-reinstall.
         (unpack_pkg_control_files): Cleaned up conffile filenames to not
         have ugly things like "///" inside them.
 
         * ipkg_download.c (ipkg_download): Cleaned up error message.
         (ipkg_download): Now uses new file_move function.
         (ipkg_download_pkg): Created new function, (from old code in ipkg_install).
 
         * ipkg_cmd.c (ipkg_download_cmd): Added new "ipkg download"
         command.
 
         * file_util.c (file_move): Created file_move, (from code that had
         been in ipkg_download).
         (file_copy): Added error message on failure.
 
         * conffile.c (conffile_has_been_modified): Eliminated crash if
         conffile_has_been_modified is called with conffile->value == NULL.
 
 2002-03-09  Carl Worth  <cworth@east.isi.edu>
 
         * RELEASE_NOTES: Added release notes for 0.99.1
 
         * configure.ac: Incremented version to 0.99.1
 
         * pkg_hash.c (pkg_hash_pkg_owning_file): Fixed to actually return
         NULL if no package owns a file.
 
         * pkg.c (pkg_get_installed_files): Added installed_files_ref_cnt
         to pkg_t to prevent pkg->installed_files from being freed from an
         inner loop while still being used by an outer loop, (which was
         happening).
 
         * pkg_hash.c (pkg_hash_pkg_owning_file): Moved this function in
         from pkg_dest.c. Also, updated it to use pkg_get_installed rather
         than mucking around inside /usr/lib/ipkg and globbing for *.list
         files.
         (pkg_hash_fetch_best_installation_candidate): Fixed to only return
         a package that actually could be installed, (ie. it must have
         either a local_filename or a non-NULL src from which it could be
         downloaded). This prevents a segfault during "ipkg upgrade".
 
         * pkg.c (pkg_get_installed_files): Fixed to not do strange things
         to filenames such as: "//./bin/sh"
 
         * ipkg_cmd.c (ipkg_files_cmd): Added pkg_free_installed_files to
         conserve a bit of memory.
         (ipkg_search_cmd): Updated to use pkg_get_installed rather than
         mucking around inside /usr/lib/ipkg and globbing for *.list files.
 
         * pkg.c (pkg_free_installed_files): Added this function to free up
         memory from pkg_get_installed_files.
 
         * ipkg_conf.c (ipkg_conf_set_option): Added force_reinstall option
         to allow reinstallation of an installed package.
 
         * args.c (args_parse): Added -force-reinstall option to enable
         reinstallation of an installed package.
 
         * busybox-0.60.2/ar.c (ar_main): Updated unarchive call to track
         prototype change.
 
         * busybox-0.60.2/libbb/unarchive.c (free_header_ar): Added
         function to plug memory leak.
 
         * ipkg_install.c (check_data_file_clashes): Fixed crash if no
         package can be found owning the pre-existing file.
 
         * pkg_dest.c (pkg_dest_deinit): Fixed bug that pkg_dest was
         holding on to freed data rather than making a local copy.
 
         * pkg_depends.c (freeDepends): Fixed crash when pkg->depends is NULL.
 
         * RELEASE_NOTES: Added release notes for 0.98.0 and 0.99.0.
 
         * busybox-0.60.2/libbb/unarchive.c (extract_archive): Fixed
         bug. Always alloc memory for full_name so we don't free data that
         we shouldn't.
         (unarchive): Updated to accept a free_headers function pointer as
         a counterpart to get_headers, to eliminate memory leaks.
         (free_header_tar): Implemented cleanup function as counterpart to
         get_header_tar, to eliminate memory leaks.
         (deb_extract): Added several calls to free_header_tar to eliminate
         memory leaks.
 
         * str_util.c (str_dup_safe): Added convenience function. Like
         strdup, but safe to use on a NULL pointer.
 
         * pkg_vec.c (pkg_vec_insert): Updated to use new pkg.c:pkg_merge
         rather than marry_two_packages. With this change the free(pkg) is
         now here rather than one level deeper. Eventually, I want to get
         this free(pkg) up and out of pkg_hash_insert.
 
         * pkg_parse.c (parseDependsString): Fixed bug walking off the end
         of the raw buffer looking for a character that isspace().
         (parseConffiles): Fixed big bug parsing Conffiles field where all
         conffiles appear on the same line.
 
         * pkg_hash.c (pkg_hash_add_from_file): Plugged memory leak of data
         allocated deep down in read_raw_pkgs_from_file.
 
         * pkg_depends.c (pkg_hash_fetch_unsatisfied_dependencies): Plugged
         memory leak, (missing pkg_vec_deinit).
         (freeDepends): Added this function as the counterpart to
         buildDepends. Getting closer to chasing down all memory leaks.
         (depend_deinit): Added this function as the counterpart to
         depend_init. Getting closer to chasing down all memory leaks.
         (parseDepends): plugged memory leak of pkg_name.
 
         * pkg.c (pkg_deinit): Added pkg_deinit to take care of freeing any
         memory owned by a pkg_t.
         (pkg_init_from_file): This function was 100% broken, (missing
         rewind).
         (pkg_merge): Moved pkg_merge here from
         pkg_vec.c:marry_two_packages. Started work to make it
         non-destructive, (not finished).
         (pkg_print_info): Added Status and Essential fields to
         pkg_print_info.
         (pkg_print_status): Fixed pkg_print_status to work whether or not
         the package is installed.
 
         * ipkg_utils.c (read_raw_pkgs_from_file): Moved fclose out of
         read_raw_pkgs_from_stream and into this function where it belongs,
         (since the fopen occurs here).
         (trim_alloc): Fixed trim to not free data passed in. Changed the
         name to make it obvious that it is allocating memory.
 
         * ipkg_install.c (ipkg_install_from_file): Fixed to be more robust
         to the fact that hash_insert_pkg sometimes frees the data that I
         pass into it (!).
         (satisfy_dependencies_for): Cosmetic change to messages.
         (satisfy_dependencies_for): Now sets the dest on to-be-installed
         packages, so that the state_want flag can be written to a status
         file if necessary.
         (satisfy_dependencies_for): Added pkg_vec_deinit to plug memory
         leak.
         (ipkg_install_pkg): Added "run ipkg update?" hint to error
         message.
         (backup_modified_conffiles): Made more robust to the case that a
         conffile has disappeared.
         (install_maintainer_scripts): Fixed bug that was installing
         maintainer scripts as libFoopostinst rather than
         libFoo.postinst. This was preventing postinst scripts from being
         executed.
         (cleanup_temporary_files): Added missing closedir to plug a memory
         leak.
 
         * ipkg_download.c (ipkg_download): Cosmetic change to error
         messages.
 
         * ipkg_conf.c (ipkg_conf_parse_file): Plugged some small memory
         leaks.
         (ipkg_conf_set_option): Changed configuration options from
         force-depends, force-defaults to force_depdends, force_defaults to
         be compatible with old ipkg.conf files.
         (ipkg_conf_set_option): Fixed bug in parsing options.
         (ipkg_conf_write_status_files): Fixed to list all interesting
         packages, (any with non-default state), in status file rather than
         just installed files.
         (ipkg_conf_write_status_files): Plugged a memory leak.
 
         * ipkg_cmd.c (ipkg_status_cmd): Changed "ipkg status" to use
         pkg_print_info so it is much more verbose, (includes fields such
         as Maintainer, etc. that are merged in from the lists files).
 
         * ipkg.h (IPKG_DEBUG_NO_TMP_CLEANUP): Added compile-time option to
         preserve temporary files for easier debugging.
 
         * file_util.c (file_md5sum_alloc): cosmetic changes to variable
         names.
         
         * ipkg_conf.c (ipkg_conf_init): Added support for offline_root
         configuration file option.
 
         * args.c (args_init): Added support for -o, -offline,
         -offline-root command-line arguments. (Although they don't really
         have any effect yet).
 
         * ipkg_install.c (ipkg_install_pkg): Changed back to marking
         package as installed before postinst, (the pkg_run_script wanted
         to find the scripts in /usr/lib/ipkg/info). Actually, it could
         probably find the script in either place at this point so maybe it
         doesn't really matter.
 
 2002-03-07  Carl Worth  <cworth@east.isi.edu>
 
         * ipkg_install.c (ipkg_install_pkg): Changed to only mark package
         as installed after running ipkg_configure, (to run the postinst
         script).
 
         * RELEASED ipkg-unstable 0.99.0
 
         * Updated all instances of "XXX" in the code to indicate one of
         the following categories:
         XXX: BUG: This is a bug that needs to be fixed.
         XXX: QUESTION: Implementation approach is uncertain here.
         XXX: CLEANUP: Suggestion on how the code could be cleaned up.
         XXX: FEATURE: Comment describes a useful feature request.
         
         * pkg.c (pkg_print_status): Added the Depends field to package
         paragraphs in the status file, ("ipkg remove" will need this).
 
         * ipkg_install.c (satisfy_dependencies_for): Fixed "ipkg install"
         to not complain several times about "Package foo already
         installed" when doing large recursive installs.
         (ipkg_install_pkg): "ipkg install foo" for an installed package
         will now check and install any missing dependencies before exiting
         with "Package foo is alrady installed."
 
 2002-03-06  Carl Worth  <cworth@east.isi.edu>
 
         * pkg_dest.c (pkg_dest_pkg_owning_file_alloc): Moved this function
         here from ipkg_install.c. Also plugged a memory leak in it with
         globfree.
 
         * pkg.c (pkg_remove_installed_files_list): Fixed bug that
         prevented package.list file from ever being removed during "ipkg
         remove".
 
         * ipkg_remove.c (remove_data_files_and_list): Fixed noisy and
         spurious warnings about non-empty directories. "ipkg remove"
         should now only say anything if a directory that was solely
         provided by that package is non-empty.
 
         * ipkg_cmd.c (ipkg_install_pending_cmd): Plugged memory leak with
         globfree.
 
         * ipkg_install.c: *Many* fixes to enable "ipkg upgrade" to more or
         less work. Primarily fixing file clash identification and conffile
         handling/resolution. "ipkg upgrade" has now worked correctly on
         several test cases!
 
         * ipkg_install.c (unpack_pkg_control_files): Now initializes
         conffiles list from the contents of conffiles control file,
         (leaves md5sum calculation until the actual conffiles are
         extracted later).
         (ipkg_install_pkg): Separated backup_modified_conffiles and
         check_data_file_clashes into separate functions.
         (preinst_configure): Simplified this function pushing its old
         logic into pkg.c:pkg_run_script.
         (backup_modified_conffiles): Added backup of any conffiles that
         are new as of this upgrade.
         (check_data_file_clashes): First real implementation of
         check_data_file_clashes.
         (resolve_conffiles): First real implementation of
         resolve_conffiles.
         (backup_make_backup): Added this and a few other functions to
         abstract backup creation/removal.
         (find_pkg_owning_file): Added this function.
         
         * pkg_extract.c (pkg_extract_data_files_to_dir): Fixed args to
         deb_extract so that existing files will be overwritten, (and any
         other error messages will no longer be suppressed).
 
         * pkg.c (pkg_print_status): Added Conffiles field to
         pkg_print_status.
         (pkg_print_field): Fixed crash when printing NULL Conffiles
         values.
         (pkg_get_conffile): Fixed crash if pkg_get_conffile called with a
         NULL pkg.
         (pkg_run_script): Made pkg_run_script smart enough to run scripts
         for uninstalled packages, (from
         <pkg_tmp_unpack_dir>/<script_name>), as well as for isntalled
         packages, (from <dest_info_dir>/<pkg_name>.<script_name>
 
         * str_util.c (str_tolower): Added convenience function.
         (str_toupper): Added convenience function.
 
         * nv_pair.c (nv_pair_init): Fixed crash from calling nv_pair_init
         with NULL value.
 
         * pkg.c (pkg_init_from_file): Fixed bug -- forgot to close file.
 
         * file_util.c (file_md5sum_alloc): Convenience wrapper around
         md5_stream as ripped out of busybox. This function takes care of
         file open/close and does the bin2hex conversion of the md5sum.
 
         * conffile.c (conffile_has_been_modified): Implemented this
         function for real now that we have md5sum capability.
 
         * md5.c (md5_stream): Sucked in md5sum calculation code from
         busybox, (it wasn't part of libbb, so I just copied the files
         straight in and ripped out uninteresting functions such as
         md5sum_main, etc.)
 
 2002-03-05  Carl Worth  <cworth@east.isi.edu>
 
         * pkg.c (pkg_print_field): Added support for printing Conffiles
         field.
 
         * ipkg_install.c (remove_obsolesced_files): With the fixed
         pkg_get_installed_files_list from below, this function now seems
         to work!
         (ipkg_install_pkg): Fixed to mark old package as uninstalled after
         upgrading.
 
         * pkg.c (pkg_get_installed_files_list): Fixed so that it's
         possible to get an "installed_files" list even from an uninstalled
         package, (it pulls the list of data files straight out of the
         package).
 
         * ipkg_cmd.c (ipkg_upgrade_cmd): Fixed ipkg_upgrade to not choke
         if asked to upgrade an un-installed package.
         (ipkg_upgrade_pkg): Fixed printing of version numbers.
 
         * file_util.c (file_mkdir_hier): Abstracted call to libbb
         make_directory into new file_mkdir_hier. At this point, the only
         calls into libbb are isolated in file_util and pkg_extract. This
         will make it easier if we ever decide to directly incorporate that
         code or rewrite it.
 
         * pkg_extract.c (pkg_extract_data_files_to_dir): Abstracted all
         calls to deb_extract in several new pkg_extract functions.
 
 2002-03-04  Carl Worth  <cworth@east.isi.edu>
 
         * ipkg_conf.c (ipkg_conf_init): Added support to ipkg_conf to
         pickup command-line arguments for "force-defaults" and
         "force-depends". Things set on the command-line should take
         precedence over things found in the configuration file.
 
         * ipkg_cmd.c (ipkg_search_cmd): Fixed formatting of "ipkg search"
         output.
 
         * pkg_depends.c (pkg_hash_fetch_unsatisfied_dependencies):
         Re-added fix to set *unresolved to NULL if depends is NULL.
 
         * xregex.c (xregexec): Removed useless error messages from NOMATCH
         calls to regexec.
 
         * ipkg_install.c (satisfy_dependencies_for): Added support for new
         "unresolved" argument in
         pkg_hash_fetch_unsatisfied_dependencies. Cleaned up warning/error
         messages.
 
         * ipkg_cmd.c (ipkg_search_cmd): Implemented first-cut of "ipkg search".
 
         * pkg_depends.c (pkg_hash_fetch_unsatisfied_dependencies): Fixed
         to set *unresolved to NULL if depends is NULL.
 
 2002-03-01  Carl Worth  <cworth@east.isi.edu>
 
         * RELEASED ipkg-unstable 0.98.0
 
         * ipkg_configure.c (ipkg_configure): Added flushing of stdout,
         (here and in a few other modules).
 
         * file_util.c (file_copy): Implemented this function here as one
         step toward isolating the calls into libbb functions. Updated old
         copy_file calls to file_copy in both ipkg_download.c and
         ipkg_install.c.
 
         * ipkg_install.c, ipkg_remove.c: Demoted several "XXX" comments to
         DPKG_INCOMPATIBILITY as I really don't intend on addressing them
         any time soon, (if ever).
 
         * ipkg_cmd.c (ipkg_files_cmd): Fixed "ipkg files" from crashing on
         uninstalled packages.
 
         * familiar/rules: Added support for easy building of an
         ipkg.ipk. The version number and the architecture are
         automatically sucked in correctly from autoconf magic, (even when
         cross-compiling). Maybe autoconf will start paying off with
         benefits rather than pain, (finally!).
 
         * configure.ac: Removed MEMCMP and STAT checks which were breaking
         cross-compilation.
 
         * ipkg_cmd.c (ipkg_upgrade_pkg): BIG bugfix: Package version
         comparison was sign-reversed, (hence it would never upgrade).
 
 2002-02-28  Carl Worth  <cworth@east.isi.edu>
 
         * ipkg_download.c (ipkg_download): Changed from
         system("/bin/cp",...) to copy_file(...)
 
         * replace/strndup.c: Implemented an (untested) replacement for
         strndup.
 
         * configure.ac: Added AC_CANONICAL_HOST to automatically set the
         correct architecture type in the ipkg control file.
 
         * configure.ac: Changed version number to 0.98.0 in preparation
         for alpha release.
 
         * familiar/rules: Added support for easy building of an ipkg.ipk.
 
 2002-02-27  Carl Worth  <cworth@east.isi.edu>
 
         * ipkg_install.c (ipkg_install_pkg): Fixed to abort on failed
         download.
 
         * pkg.c (pkg_run_script): Fixed bug that was preventing any
         package maintainer scripts from running, (hence, they run now so
         running non-native offline no longer works until I figure out the
         chroot plans).
 
         * TODO: Added rough outline of remaining features with a release
         schedule.
 
         * pkg_parse.c (pkg_parse_raw): Added parsing of "MD5Sum" in
         addition to "MD5sum" to accomodate bug in old ipkg.
 
         * void_list.c (void_list_remove): Added new remove function, (also
         adjusts a forward iterator). Required new list->pre_head member
         which was added to all sub-list types.
 
         * pkg.c (pkg_init): Changed pkg->conffiles to be of the new
         conffile_list_t datatype.
         (pkg_remove_installed_files_list): Pulled this function into
         pkg.c, (from ipkg_remove.c), so the mallocs and frees would be in
         the same C file.
         (pkg_get_conffile): Added this convenience function.
 
         * ipkg_remove.c: Fixed several bugs. ipkg_remove now actually
         works for simple packages!
 
         * ipkg_install.c (ipkg_install_pkg): Don't re-install if a package
         is already installed.
         (ipkg_install_pkg): Fixed major bug that all of ipkg_install's
         work was always being unwound even when successful.
 
         * ipkg_cmd.c (ipkg_files_cmd): Fixed to use
         pkg_get_installed_files_list rather than a private implementation
         that sifted through the file lists on disk.
 
         * str_util.c (str_ends_with): Added this convenient function.
         (str_chomp): Another convenience.
 
         * ipkg_conf.c: Moved chomp to str_util.c (str_chomp), since
         someone else wanted it too.
 
 2002-02-26  Carl Worth  <cworth@east.isi.edu>
 
         * pkg_parse.c (pkg_parse_raw): Added XXX requesting parsing of
         Conffiles: field along with a hint about how to store the data.
 
         * conffile_list.c:  Added a little wrapper around nv_pair_list
 
         * conffile.c: Added a little wrapper around nv_pair
 
         * str_util.c (str_ends_with): New convenience function.
 
         * str_list.c (str_list_remove): Plugged in remove function.
 
         * void_list.c (void_list_remove): Added remove function, (handles
         updating of forward iterator).
 
         * pkg.c (pkg_run_script): Changed to return return value of
         script.
 
         * ipkg_remove.c: Fleshed out initial version of all ipkg_remove.c
         functions.
 
         * ipkg_configure.c (ipkg_configure): Added check on return value
         of pkg_run script. Added comments about dpkg compliance.
 
         * ipkg_cmd.c (ipkg_purge_cmd): Added ipkg_purge_cmd
 
 2002-02-20  Carl Worth  <cworth@east.isi.edu>
 
         * Added USC copyright statements, (and Compaq stubs as necessary)
 
         * ipkg_install.c: At this point "ipkg install" on a simple
         package, (no scripts and no dependencies), works just fine. It
         might even do some of the script and dependency handling correctly
         too, but I haven't tested that yet. "ipkg install libc6" is a nice
         little test that should complete without any errors or
         warnings. Follow that up with "ipkg status" to see that it worked.
 
         * pkg.c (pkg_run_script): Added convenience method for running
         package scripts.
 
         * ipkg_install.c: Fixed several bugs:
         (unpack_pkg_control_files): control files now extract to the
         correct temporary directory.
         (ipkg_install_pkg): pkg->state_want is now properly set to SW_INSTALL
         (ipkg_install_pkg): status file now gets written after installation
         (cleanup_temporary_files): All temporary files are cleaned up.
 
         * ipkg_configure.c (ipkg_configure): Fleshed out a very simple
         ipkg_configure, (simply runs "postinst configure"). Maybe it will
         need to be smarter at some point. Moved unwritten conffiles stuff
         back to ipkg_install.c.
 
         * ipkg_conf.c (ipkg_conf_write_status_files): Moved this function
         from ipkg_utils to ipkg_conf since it needs access to the
         pkg_dest_list.
 
         * pkg_vec.c (marry_two_packages): Added several missing fields,
         (state_want, state_flag, filename, local_filename, tmp_unpack_dir,
         md5sum, size, installed_size, priority, source, conffiles,
         isntalled_files, essential)
 
 2002-02-19  Carl Worth  <cworth@east.isi.edu>
 
         * ipkg_install.c: several little bug fixes. "ipkg install" will
         now actually install files from a package! There are still some
         bugs, (eg. postinst scripts are not called -- probably other
         things as well). But, it's coming together now.
 
         * pkg_dest.c (pkg_dest_init): now creates all necessary directories
 
         * ipkg_download.c (ipkg_download): Fixed misleading parameter name.
 
         * ipkg_conf.c (ipkg_conf_deinit): Now cleans up tmd_dir on deinit
         ipkg.c: now calls ipkg_conf_deinit before exiting.
         (ipkg_conf_add_nv): Fixed to set default_dest when parsing first
         dest in ipkg.conf
 
         * ipkg_cmd.c (ipkg_list_cmd): Fixed ugly bug in ipkg_list that led
         to infinite loops, segfaults, string corruption, and other bizarre
         behavior.
 
         * Added many files as we are approaching the first functional ipkg
         implementation in C:
         file_util.c: convenience for testing if file_exists, reading files, etc.
         ipkg_configure.c: mostly just a stub so far
         ipkg_download.c: convenient function to download a file
         nv_pair.c: data structure to hold a name-value pair
         nv_pair_list.c: data structure to hold a list of nv_pair_t
         pkg_dest.c: data structure for everything a pkg destination wants
         pkg_dest_list.c: data structure to hold a list of pkg_dest_t
         pkg_extract.c: convenience functions for package extraction,
         (these function should encapsulate any libbb borrowings we perform
         -- although some slipped into other files already)
         pkg_src.c: everything you might need for a pkg src.
         pkg_src_list.c: data structure to hold a list of pkg_src_t
         str_list.c: data structure to hold a list of char *
         void_list.c: generic linked-list data structure and functions
         xsystem.c: wrapper around system() with error checking
 
         * ipkg_remove.c: Just added some stubs. Nothing really works at
         all yet.
 
         * ipkg_install.c: Large rework of ipkg_install. It's now close to
         actually being usable, (but it's not quite there yet). Revamped to
         match dpkg install order more closely, (with all the stubs in case
         we ever want to call all the scripts that dpkg does). Also updated
         to use a more recent deb_extract from libbb.
 
         * ipkg_extract_test.c (main): Added support for a third arg, (the
         filename to extract to the buffer).
 
         * ipkg_conf.c (ipkg_conf_init): Added several fields to
         ipkg_conf_t: pkg_src_list, pkg_dest_list ,
         restrict_to_default_dest, default_dest, tmp_dir, lists_dir,
         pending_dir, force_depends, and pkg_hash. There's still a bit of
         tension between options stored in the config file, (ipkg_conf_t),
         and command-line arguments, (args_t).
 
         * ipkg_cmd.c: First version that is approaching usability. The
         following commands are more-or-less in place: "ipkg update", "ipkg
         list", "ipkg info", "ipkg status". While the rest are in various
         states of being partiallyy written or written but untested.
         (ipkg_upgrade_cmd): Added support for restricting to a dest.  Many
         other changes, largely involving plugging into the pkg_hash for
         real for the first time, and adding multiple dest support.
 
         * ipkg.c: Added support for setting the dest on the command-line.
 
         * args.c: Added support for IPKG_CONF_DIR environment variable and
         -f, -conf, and -conf-file options.
 
         * configure.ac: Added lots of little bits suggested by autoscan.
 
 2002-02-18  Carl Worth  <cworth@east.isi.edu>
 
         * pkg_parse.c (pkg_parse_raw): Added parsing, (kinda ugly), for
         essential field.
         * pkg.c (pkg_print_field): Added the essential flag.
 
         * pkg_vec.c (pkg_vec_insert): Fixed to use pkg_compare_versions to
         determine matching versions instead of a strcmp on the version
         string.
 
 2002-02-15  Carl Worth  <cworth@east.isi.edu>
 
         * pkg_parse.c (pkg_parse_raw): Updated to accept a pkg_src_t
 
         * pkg.c (pkg_init): Added field to pkg_t: "pkg_src_t *src"
 
         * pkg_hash.c (pkg_hash_add_from_file): Updated to accept a pkg_src_t
 
         * pkg_parse.c (parseStatus): Modified to accept a pkg_t *
         (parseVersion): Added this function
         (pkg_parse_raw): Updated to accept a pkg_dest_t
         (pkg_parse_raw): Reworked the parsing to use a pkg_t rather than a
         slew of local variables.
         (pkg_parse_raw): Added support for about a dozen new pkg_t fields
 
         * pkg.h: Updated for all pkg.c changes.
 
         * pkg.c (pkg_new): Added pkg_new for convenient alloc'ing of a pkg_t.
         (pkg_init): Added several fields to pkg_t: dest, section,
         suggests, filename, local_filename, tmp_unpack_dir, md5sum, size,
         installed_size, priority, source, and conffiles.
         (): Moved buildPkg this function to pkg_parse
         (pkg_init_from_file): Added convenience function for filling a
         pkg_t from an actual package file.
         (pkg_print_info): Split print_pkg into both pkg_print_info and
         pkg_print_status.
         (pkg_print_field): Added pkg_print_field, (extremely ugly)
         (): Moved parseversion to pkg_parse where it belongs
         (pkg_version_str_alloc): Added, (complement of parse_version)
 
         * pkg_depends.h: Added GPL blurb
         (PKG_DEPENDS_H): Added multiple include protection
 
         * pkg_depends.c: Moved non-static prototypes to header file.
         Changed several locl-only functions to be static.
         Added function prototypes for static functions.
         (buildDepends): Removed unecessary cast of malloc return value.
 
         * pkg_hash.h: Moved hash-related struct declarations to this file
         Rename pkg_fetch* to have consistent pkg_hash_fetch prefix.
         Added missing prototype for pkg_vec_fetch_by_name
 
         * pkg_hash.c: (pkg_hash_add_from_file): Added support for setting
         the pkg_dest
         (pkg_hash_add_from_file): Moved buildDepends call to
         hash_insert_pkg
         (pkg_hash_fetch_installed_by_name_dest): Added this function to
         support pkg_dest
 
         * ipkg_utils.h: Added GPL blurb
         (IPKG_UTILS_H): Added multiple include protection
 
         * ipkg_utils.c:
         (read_raw_pkgs_from_file): broke read_raw_pkgs into
         read_raw_pkgs_from_file and read_raw-pkgs_from_stream
         (ipkg_write_status_file): Fixed return value
         (print_pkg_status): Moved this function to pkg.c:pkg_print_status
         (line_is_blank): Fixed const char handling
 
 2002-02-08  Carl Worth  <cworth@east.isi.edu>
 
         * pkg_parse.c: Fixed a bug in parsing the 3 state fields.
 
 2002-02-06  Carl Worth  <cworth@east.isi.edu>
 
         * pkg.c: Expanded pkg_status field to the full 3 fields: state_want,
         state_flag, and state_status.
 
 2001-12-11  Carl Worth  <cworth@east.isi.edu>
 
         * ipkg_conf.c: Now parses /etc/ipkg.conf, (and doesn't do anything
         with it).
 
         * ipkg.c: Started work on ipkg main, (not much here yet).
 
         * ipkg_cmd.h: Added a tiny thing to abstract top-level ipkg
         commands, (not finished).
 
         * Set up autoconf and friends
