2006-10-01g[un]zip: add support for -v (verbose).Denis Vlasenko
Add CONFIG_DESKTOP, almost all bloat from this change is hidden under that.
2006-09-30vconfig: fix bug 701 (I be damned if I understand it)Denis Vlasenko
2006-09-17whitespace cleanupDenis Vlasenko
2006-09-06removed a lot of trailing \n in bb_msg() calls. It is addedDenis Vlasenko
automatically by function itself.
2006-08-03Remove bb_ prefixes from xfuncs.c (and a few other places), consolidateRob Landley
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only had one user), clean up lots of #includes... General cleanup pass. What I've been doing for the last couple days. And it conflicts! I've removed httpd.c from this checkin due to somebody else touching that file. It builds for me. I have to catch a bus. (Now you know why I'm looking forward to Mercurial.)
2006-07-16Cleaup read() and write() variants, plus a couple of new functions likeRob Landley
xlseek and fdlength() for the new mkswap.
2006-07-01Remove all usage of the "register" storage class specifier."Robert P. J. Day"
2006-06-25Various cleanups I made while going through Erik Hovland's patch submissions,Rob Landley
some of which are even from him. :)
2006-04-10Patch from Rob Sullivan to consolidate crc32 table generation.Rob Landley
2006-04-02- janitorial: huft_build is never used outside of decompress_unzip.c and has noBernhard Reutner-Fischer
prototype (which suggests that it's of no general use) so make it static for now.
2006-03-10Patch from Denis Vlasenko turning static const int (which gets emitted intoRob Landley
the busybox binary) into enums (which don't).
2006-03-06Robert P. Day removed 8 gazillion occurrences of "extern" on functionRob Landley
definitions. (That should only be on prototypes.)
2006-02-20The gentoo security guys found another way to segfault busybox's decompressionRob Landley
code: we can do a null dereference if one of our huffman tables has all zero length codes. This fixes it. (Thanks solar.)
2006-01-30fixup a few types to prevent gcc (rightfully) whining about mixingEric Andersen
signed and unsigned, unmatches pointer target types, etc
2006-01-10Don't return 0 when there's an error.Rob Landley
2005-10-07- remove superfluous C statements ";;" in decompress_unzip.c, dpkg_deb.c ↵Bernhard Reutner-Fischer
ifconfig.c - gzip.c: see if O_NOFOLLOW is defined before using it, else take alternate path closes bug #221 (partially; The rest will follow later).
