init_archive_deb_data()
We want to filter for data.tar.* in the AR file not the TAR
file, else we get nothing.
all_control_list()
Make the 'extensions' array of control file names a global so it
can be used in unpack_package as well. Name the global
all_control_files. Don't hard code the length of
all_control_files but instead used sizeof.
unpack_package()
Only unpack the control files we are interested in (from
all_control_files). Extract the data.tar.gz into / rather than
the current directory.
dpkg_main()
Configure packages in a second pass so all the packages being
installed are unpacked before configuring.
Some purely cosmetic changes:
header
update list of differences since two of them are no longer true.
The .control file is no longer stored as a result of this patch
-- it was redundant since the info is in status. New packages
appear to be added to the end of the status file now rather than
the start.
remove_package()
Make message printing optional, so we can avoid a redundant
message when replacing/upgrading a package. When we do print
stuff then include the version number.
purge_package()
Print "Purging xxx (yyy) ..." message like the other actions.
configure_package()
Add "..." to "Setting up" message to be consistent with other
actions.
archive_xread can be replaced with bb_full_read, and archive_copy_file
with bb_copyfd*
bb_copyfd is split into two functions bb_copyfd_size and bb_copyfd_eof,
they share a common backend.
open_transformer(), common code for pipe+fork.
Function pointer for read() no longer needed.
Allow inflate to be initialised with a specified buffer size to avoid
over-reading.
Reset static variables in inflate_get_next_window to fix a bug where
only the first file in a .zip would be be extracted.
Hi Glenn.
I analysed BSS size gzip applet and found may be mistake:
updcrc() checking if (crc_table_empty) but not resetted this var.
This do make slow gzip applet ;-)

Use the old fork() method of tar compression support, rather than
read_bz2....
- (*uncompress)(int in, int out) seems like a more natural interface
for compression code.
- it might improve performance by seperating the work into one cpu
bound and one io bound process.
- There is extra code required to do read_[gz|bunzip] since (*uncompress)(int in,
int out) will normally be used by the standalone compression applet.
There have been problems with this method so if you see a "Short read"
error let me know.
