From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020311 Description of problem: -x exclude options in lftp's mirror subcommand seem to match more loosly than would be expected. Using lftp to mirror redhat's updates (ftp.redhat.com/pub/redhat/linux/updates/) the -x option matched too loosely and cause some packages to be missed during the mirror. I had -x .nfs* as one of my exclude options and it cause at least 7 files to be skipped as a result. (* is used below to omit version numbers not be inclusive of packages) The packages skipped were: printconf-*src.rpm redhat-config-network-*-src.rpm Xconfigurator*.i386.rpm nfs-utils-*.i386.rpm printconf-*.i386.rpm printconf-gui.i386.rpm xemacs-info-*.i386.rpm printconf-*.ia64.rpm printconf-gui-*.ia64.rpm redhat-config-network-*.noarch.rpm lftp script is as follows: /usr/bin/lftp <<CONF open ftp.redhat.com lcd /app/mirrors/redhat/7.2/updates/os cd /pub/redhat/linux/updates/7.2/en/os mirror -e -x .nfs* CONF I found this problem with lftp on a 6.2 box, but it was verified by someone else on a 7.2 box as well. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. create appropriate directories referenced in above script 2. create and run the above shell script 3. check for existance of the above listed packages (Xconfigurator, etc) Actual Results: it will mirror 90% of the data there, but it will leave out the listed packages and possible others. Expected Results: should have mirrored all the packages in that directory including the listed ones. Additional info: lftp version: 2.1.5 it appears that it's match is too loose, like it's matching the n or the f or s. Or something similar. it is worked around by quoting the arguement to the mirror comamnd ... mirror -e -x '.nfs*' ...
behavior confirmed in 7.2 x86 (lftp-2.4.0-2).
Just clearing out old bugs here . The latest version of lftp is 3.0.6 and I have confirmed that its mirror -x RE and mirror -X GLOB commands work OK. This bug could have resulted from some confusion about -x option: The -x option expects an extented regular expression as in egrep(1), so .nfs* matches any character followed by 'nf' followed by a (perhaps empty) sequence of 's' chars, so the following all match: onf inf etc. lftp now provides the mirror -X glob option so '-X *.nfs*' would do what I think you were expecting here.
