From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-12 i686; Nav) Description of problem: If you use cpio to extract a multiply linked file from an archive, and you tell cpio to exclude the first link, the resulting linked files have 0 length. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Take an rpm that contains multiply-linked files. glibc-common is an example. 2. Using rpm2cpio, extract the cpio archive from the rpm, and then pass it through cpio, extracting all files. This will work properly, and all files will have the proper size. Now do the same but exclude the first listed link of some file. All other links to this file will be created, but with 0 length. 3. Actual Results: [admin@apphost-60 cpio_test]$ rpm2cpio ../glibc-common-2.2.4-13.i386.rpm | cpio -id --quiet '*usr/lib/locale/en_US/*' > /dev/null [admin@apphost-60 cpio_test]$ ls -l usr/lib/locale/en_US/ total 12 -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_ADDRESS -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_COLLATE -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_CTYPE -rw-r--r-- 1 admin admin 370 Nov 15 17:04 LC_IDENTIFICATION -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_MEASUREMENT drwxr-xr-x 2 admin admin 4096 Nov 15 17:04 LC_MESSAGES -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_MONETARY -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_NAME -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_NUMERIC -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_PAPER -rw-r--r-- 1 admin admin 0 Nov 15 17:04 LC_TELEPHONE -rw-r--r-- 1 admin admin 2456 Nov 15 17:04 LC_TIME Expected Results: [admin@apphost-60 cpio_test]$ rpm2cpio ../glibc-common-2.2.4-13.i386.rpm | cpio -id --quiet '*' > /dev/null [admin@apphost-60 cpio_test]$ ls -l usr/lib/locale/en_US/ total 240 -rw-r--r-- 2 admin admin 160 Nov 15 17:05 LC_ADDRESS -rw-r--r-- 37 admin admin 21499 Nov 15 17:05 LC_COLLATE -rw-r--r-- 61 admin admin 173408 Nov 15 17:05 LC_CTYPE -rw-r--r-- 1 admin admin 370 Nov 15 17:05 LC_IDENTIFICATION -rw-r--r-- 3 admin admin 28 Nov 15 17:05 LC_MEASUREMENT drwxr-xr-x 2 admin admin 4096 Nov 15 17:05 LC_MESSAGES -rw-r--r-- 2 admin admin 291 Nov 15 17:05 LC_MONETARY -rw-r--r-- 2 admin admin 82 Nov 15 17:05 LC_NAME -rw-r--r-- 15 admin admin 59 Nov 15 17:05 LC_NUMERIC -rw-r--r-- 5 admin admin 39 Nov 15 17:05 LC_PAPER -rw-r--r-- 2 admin admin 64 Nov 15 17:05 LC_TELEPHONE -rw-r--r-- 1 admin admin 2456 Nov 15 17:05 LC_TIME Additional info: [admin@apphost-60 cpio_test]$ rpm -q cpio cpio-2.4.2-23
Created attachment 37682 [details] patch against 2.4.2-20 to fix the problem, will likely apply against 2.4.2-23
