When query "_db_path", it returns nothing and causes segmentation fault. 32272 2 kai.kang 2013-04-17 09:17:52 +0000 Patch v2 has been sent to oe-core, and postpone it to 1.5 32602 3 n3npq 2013-04-24 16:51:13 +0000 The simplest fix of all is to use rpm2cpio.sh, an ~38 line shell script. 44881 4 jeff.polk 2014-07-31 15:05:36 +0000 Mark asked me to move this to future. The script works correctly but he'd like to keep the reminder to check whether it's fixed in future versions. 44900 5 n3npq 2014-07-31 18:11:15 +0000 Using rpm2cpio.sh is still the best fix for Yocto imho. The segfault comes from attempting to locate the pubkey needed to verify the header signature in the rpmdb Pubkeys index. The path to the rpmdb is stored in in the %_dbpath macro. The rpmdb pubkey lookup is now (rpm-5.4.15) skipped if %_dbpath isn't set (which fixes the segfault). Implicitly disabling package signature verification depending on macro (mis-)configuration may not be supportable when rpmlib needs to always verify signatures. 49052 6 ross.burton 2015-02-25 15:48:36 +0000 http://patchwork.openembedded.org/patch/59135/ is the patch that Kai sent, and Mark rejected it. Mark/Kai - presumably this is still a problem - can someone revisit this and prepare a correct patch? 49053 7 mark.hatle 2015-02-25 15:58:10 +0000 This is still a bug, but we moved to using the script version of rpm2cpio on the rpm-native side. Thus this is very low priority. It might be fixed at some point in the future, but it's really an issue on how the recent binary versions of rpm2cpio inteface w/ the rpmlib and rpmlib interfaces with external files. (None of that is actually needed for our usage case, thus the scripted version works fine.) The bug was left open, because well.. it is a bug. (very low priority) We're just going to continue to monitor the situation, and we'll fix it if/when the upstream design changes. Again, this only affects rpm-native, not the target rpm. --Mark 49056 8 n3npq 2015-02-25 16:35:29 +0000 There's a modest improvement to rpm2cpio.sh for Cygwin available here: http://stackoverflow.com/questions/18787375/how-do-i-extract-the-contents-of-an-rpm/25986787#25986787 75201 9 richard.purdie 2017-07-20 16:02:23 +0000 rpm2cpio works fine with rpm v4 so closing this a resolved.
