Glenn L McGrath ba49651de9 Check there are files to add the archive before removing a specified 
tar file.

Glenn L McGrath 3b9fc8fe2a Make unlink old files default behaviour and add a new option -k to 
prevent overwritting existing files

Glenn L McGrath eba86e2adb Catch unsupported features 2003-11-14 12:53:42 +00:00
Glenn L McGrath 91b3d460c7 Fix -C option when creating tar files. 
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.

Eric Andersen e3393513c5 Be certain to not abort prematurely when reading stuff from pipes. 2003-07-05 23:10:27 +00:00
Eric Andersen 3c5a83c567 As noted by Thomas Eckert: 
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.

Eric Andersen a21f4e018a Glenn McGrath (bug1) isaway from my email till the 17th, but caught me on IRC. 
He took a look into the recent reports of tar problems, and found an obvious
typo in last_patch91 from vodz which converted tar to use bb_getopt_ulflags.

Eric Andersen 18921bd00d A bugfix from Danny Lepage: 
It seems that under busybox unstable, "tar -c -f - blabla" create
    a tar file named "-" instead of writing to stdout.

    The included patch should fix this.

Eric Andersen 71ae64bdc6 last_patch61 from vodz: 
New complex patch for decrease size devel version. Requires previous patch.
    Also removed small problems from dutmp and tar applets.

    with libbb (very reduce size if used "cat" applet also).

Eric Andersen 02e6ba91e8 Vodz' last_patch57: 
Hi, Erik.

    my_getpw(uid/gid) and applets used it have problem:
    if username for uid not found, applets can`t detect it
    (but code pessent). Also "%8ld " format is bad:
    spaces not required (applets have self format
    or spec format (tar applet) and overflow for "id" applet...)
    This problem also pressent in stable version.
    Patch for unstable in attach.

Eric Andersen aff5e2eaef it turs out, there was a nasty tar bug where bb tar would create leading dirs 
with mode 0777 in all cases due to usask issues.  Thanks to Matt Kraai for
noticing and spotting the culprit.  This makes bb tar behave just like GNU
tar once again.

Eric Andersen cb2a372c9f Revert the patch from Konstantin Boldyshev <konst@linuxassembly.org> to never 
change permissions on existing directories.  This behavior is contrary to SUSv2
and contrary to GNU tar.  Thanks to Matt Kraai for pointing this out.  I should
have been much more careful about accepting such a patch.

readlink(2).

Glenn L McGrath af166e7ce0 Logic reversal for last_char_is 2001-04-29 00:50:33 +00:00
Eric Andersen c1bdffe99b Another nice cleanup from Larry. This adds a new last_char_is() function and 
uses it to avoid possible buffer underruns whn strlen is zero, and avoid the
possible space-hogging inline of strlen() in several cases.
 -Erik
 2001-04-26 15:56:47 +00:00
Eric Andersen 04095e58fb Move messages.c to libbb. Make each string in messages.c be its own .o file. 
This way, we can new get rid of all that tedious #define rubbish we used to
need to enable specific messages.  This way is enormously simpler, and as a
bonus also ends up saving us 96 bytes.

Eric Andersen 3e6ff9017f A cleanup patch from Jeff Garzik to static-ify a number of 
namespace polluting things that really should be static.
 2001-03-09 21:24:12 +00:00
Eric Andersen cbe31dace5 It turns out that DODMALLOC was broken when I reorganized busybox.h 
header file usage before the 0.49 release.  To fix it, I had to move
the '#include "busybox.h"' to the end of the list of #include files.

Eric Andersen 67991cf824 This patch, put together by Manuel Novoa III, is a merge of work

are displayed.

Eric Andersen ed3ef50c23 Fix header file usage -- there were many unnecessary header files included in 
busybox.h which slowed compiles.  I left only what was needed and then fixed up
all the apps to include their own header files.  I also fixed naming for pwd.h
and grp.h functions.  Tested to compile and run with libc5, glibc, and uClibc.
