It's up. Check out http://home.earthlink.net/~noodlez84/rpm_packages.html . It's working, but I have some problems / questions (I couldn't find a star mailing list, so I hope I don't get beaten down for this post): 1. On my machine, star is SLOW... More than 7x slower on average than GNU tar... That can't be right. linux:~ # time star -z -x -f star-1.4a08.tar.gz -C=/tmp/ star: 234 blocks + 9216 bytes (total of 2405376 bytes = 2349.00k). real 0m17.925s user 0m0.420s sys 0m1.550s linux:~ # rm -rf /tmp/star-1.4/ linux:~ # time tar --gzip -xf star-1.4a08.tar.gz -C /tmp/ real 0m1.620s user 0m0.460s sys 0m0.650s linux:~ # rm -rf /tmp/star-1.4/ linux:~ # time gzip -dc star-1.4a08.tar.gz | star -x -f - - C=/tmp/ star: 234 blocks + 9216 bytes (total of 2405376 bytes = 2349.00k). real 0m15.408s user 0m0.420s sys 0m1.570s linux:~ # rm -rf /tmp/star-1.4/ linux:~ # time bzip2 -dc fubar.tar.bz2 | star -x -f - -C=/tmp/ star: 262 blocks + 0 bytes (total of 2682880 bytes = 2620.00k). real 0m10.099s user 0m2.320s sys 0m0.970s linux:/tmp # time star -x -f fubar.tar star: 262 blocks + 0 bytes (total of 2682880 bytes = 2620.00k). real 0m10.515s user 0m0.060s sys 0m0.860s linux:/tmp # rm -rf fubar linux:/tmp # time tar -xf fubar.tar real 0m0.676s user 0m0.040s sys 0m0.440s linux:/tmp # In the last operation, star used ~15.7% of my RAM (total :32MB). GNU tar only ~2.7%. I would have no qualms about using star over GNU tar if it was faster even if it used more RAM. 2. There are several cool things in GNU tar that don't work in star. Here's a list: options :: star equivalent o -cf :: -c -f o -xf :: -x -f o -C /fubar :: -C=/fubar IMO, these options should be added if not for user convenience, then for GNU tar compatibility. 3. Is there a way to remove files from tar archives using star? 4. I noticed the following files are installed when 'make install'ing Schilling programs: /usr/include/align.h /usr/include/avoffset.h /usr/lib/libdeflt.a /usr/lib/libfile.a /usr/lib/libhfs.a /usr/lib/librscg.a /usr/lib/libscg.a /usr/lib/libschily.a /usr/lib/libunls.a What are they used for? Should I include them in my RPMs? If you take a peek at http://home.earthlink.net/~noodlez84/rpm_packages.html , I have a devel RPM for every Schilling package I compile. Is this the "right" way? 5. Joerg Schilling: I read your GNU tar rant in the rather lengthy README.otherbugs, and I must say, I agree with you. Even the folks at 'file' know that GNU tar != POSIX tar: linux:~ # file some_gnu_tar_file.tar some_gnu_tar_file.tar: GNU tar archive linux:~ # file some_star_archive.tar some_star_archive.tar: POSIX tar archive BTW, I apologize for the length of this message. -- Karol Pietrzak PGP KeyID: 3A1446A0 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
