| 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).

| 2003-10-18 | Rob 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. | |||

| 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). | |||
| 2003-09-09 | If a tar entry is a regualr file ending in a '/' then its really a | Glenn 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. | |||
