2003-11-18Dont close original file handle, we may need it later.Glenn L McGrath
2003-11-18Make unlink old files default behaviour and add a new option -k toGlenn L McGrath

2003-11-15Move from read_gz to the pipe()+fork() method.Glenn L McGrath
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 ;-) --w vodz
2003-11-07This appears to be the correct fix to make CONFIG_FEATURE_DEB_TAR_BZ2Eric Andersen
support compile. Glenn, you may want to verify this. -Erik

2003-11-05Fix tar -j supportGlenn L McGrath
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.

new code returns 0 for success.
2003-10-28Conditionally compile some files.Glenn L McGrath
This hides a bug related to the new bunzip code in the tar and dpkg[-deb] applets. It will also reduce compile time a little as some unused files wont be compiled.

the busybox menuconfig triggered my "inacceptable number of spelling mistakes" upper level, so I decided to make a patch ;-) I also improved some wording to describe some things in a better way. Many thanks for an incredible piece of software! Andreas Mohr, random OSS developer

Hello Rob, Here's a patch to your bunzip-3.c file. Nice work btw. One minor bug fix... checking for error return when read()ing. Some size/performance optimizations as well. One instance of memset() seems unnecssary. You might want to take a look. Anyway, on my machine, decompressing linux-2.6.0-test7.tar.bz2 to /dev/null gave the following times: bunzip-3.c bzcat (system) bunzip-3.c (patched) real 0m24.420s 0m22.725s 0m20.701s user 0m23.930s 0m22.170s 0m20.180s sys 0m0.070s 0m0.080s 0m0.140s Size of the patched version is comparable (slightly larger or smaller depending on compiler flags).

2003-10-18Rob Landley's new micro-bunzip version 3. Rob writes:Eric Andersen
The API for using partial writes, as described in my last message, sucked. So here's a patch against my last patch that changes things so that write_bunzip_data calls read_bunzip_data itself behind the scenes whenever necessary. So usage is now just start_bunzip(), write_bunzip_data() until it returns a negative number, and then the cleanup at the end of uncompressStream. It adds 32 bytes to the executable, but it should allow the caller (tar) to be simplified enough to compensate. Total -Os stripped exe size now 6856 bytes. Rob P.S. I attached the whole C file so you don't have to keep incremental patches straight if you don't want to. :) P.S. In the version I'm banging on now, I've simplified the license to just LGPL. I read the OSL a bit more closely and the patent termination clause would have bit IBM in their counter-suit of SCO if the code in question had been OSL instead of GPL, and I've decided I just don't want to beta-test legal code right now.
2003-10-02Fix -C option when creating tar files.Glenn L McGrath
Need to chdir after the tar file is opened, so make common tar filename parsing and send the file descriptor rather than filename to writeTarFile. Modify the verboseFlag operation to determine wether to display on stderr or stdout at display time, simpler than doing it in tar_main.

modes, fixes a bug extracting hardlinks to symlinks.
2003-09-11Marc A. Lehmann writes:Eric Andersen
The tar -x command in busybox does not restore the file mode correctly. The reason is most probably this code in archival/libunarachive/data_extract_all.c: chmod(file_header->name, file_header->mode); chown(file_header->name, file_header->uid, file_header->gid); chown clears the set*id bits (on current versions of linux :). Flipping the order around fixes the problem. (tested with 1.00pre3 from cvs).
2003-09-09If a tar entry is a regualr file ending in a '/' then its really aGlenn L McGrath
directory. From http://www.gnu.org/manual/tar/html_node/tar_123.html REGTYPE AREGTYPE These flags represent a regular file. In order to be compatible with older versions of tar, a typeflag value of AREGTYPE should be silently recognized as a regular file. New archives should be created using REGTYPE. Also, for backward compatibility, tar treats a regular file whose name ends with a slash as a directory.

2003-07-31Fix bug when handling debian packages.Glenn L McGrath
If we read the contents of compressed files within the ar archive, e.g. control.tar.gz, then file position gets all out of whack, so it has to be reset before reading thenext header.

2003-07-14Patch from Thomas Cameron:Eric Andersen
Hello all, This patch adds more "Help" text to the config system. Almost all applets now have a help entry. Also, I cleaned up the spacing of the existing text so that things are consistent. This patch is against this morning's CVS. Thomas Cameron CEI Systems, Inc.
2003-07-05Be certain to not abort prematurely when reading stuff from pipes.Eric Andersen
2003-07-05As noted by Thomas Eckert:Eric Andersen
bb-tar "cjf" does not create a valid tbz2-archive -- if fact the result is a plain tar-file (no compression) -- but does not warn about the unrecognized parameter combination "cj" (bb does not have bzip2-compression yet, right?). to fix this I have added an error message stating this does not work. He also reported cosmetic: versose "-v" does not show any output when used with "create" which I have now fixed as well. -Erik
