last xcalloc replaced by xzalloc
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.
2006-08-03Remove 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.)

2006-04-02- include proper prototypes in libunarchive.Bernhard Reutner-Fischer
2006-03-06Robert P. Day removed 8 gazillion occurrences of "extern" on functionRob Landley
definitions. (That should only be on prototypes.)
2006-03-01Cleanup patch from Denis Vlasenko. Mostly variants of removing the if(x)Rob Landley
from before "if(x) free(x)".
2006-02-17Fix for an integer overflow bug that could cause a segfault on certainRob Landley
pathological archives. (Unlikely to have security implications, the only way to trigger it basically wound up doing memset(dbuf,x,2^31) and triggering an immediate segfault. The test basically gives us a more polite error message.) Thanks to Ned Ludd and the Gentoo security guys for finding this.
2006-02-17The tendency of vi to auto-indent can be really annoying at times.Rob Landley

2004-04-14Larry Doolittle writes:Eric Andersen
This is a bulk spelling fix patch against busybox-1.00-pre10. If anyone gets a corrupted copy (and cares), let me know and I will make alternate arrangements. Erik - please apply. Authors - please check that I didn't corrupt any meaning. Package importers - see if any of these changes should be passed to the upstream authors. I glossed over lots of sloppy capitalizations, missing apostrophes, mixed American/British spellings, and German-style compound words. What is "pretect redefined for test" in cmdedit.c? Good luck on the 1.00 release! - Larry
2004-03-15Remove trailing whitespace. Update copyright to include 2004.Eric Andersen
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.
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.
2003-10-31Put back the tar support stubs (and warnings) for now.Eric Andersen
