[SOLVED] Re: mkisofs bug? creating cdrom image for bulk files with -old-root -> enter infinite loop?
Thank you for all your help. Now I have solved my problem. I identified two problems which are not directly related I guess. 1. when using -M /dev/hdd -> mkisofs would hang up in an infinite loop (consume CPU), this only happen to 2.0.1 version, the latest pre-alpha version don't have this problme (I succeeded in making the iso image 2. when using -M /tmp/first.iso -> mkisofs hangs, enter 'S' status, do not consume CPU, this happen to both versions of mkisofs. Currently not sure if this is a bug. I lost first.iso file by removed it accidentally, thus no longer able to reproduce this problem. Using -M /dev/hdd plus latest mkisofs now I can burn the CDR just fine. Thank you! signature.asc Description: 这是信件的数 字签名部分

I tried the 'lastest' one version 2.01.01a16-pre. Still fail with the same behavior. I am still trying to get a back trace.

mkisofs bug? creating cdrom image for bulk files with -old-root -> enter infinite loop?
Hello. I actually encounter this problem on SuSE linux, but I am pretty sure I can reach the mkisofs authors much easier on this list, as this could be a bug report, it's important to reach the authors/maintainers. I managed to learn to use -old-root to create CDR with only updated files, see my previous post (attached at the end of this email). Here is how to reproduce this 'bug': insert an empty CDR, do this [EMAIL PROTECTED]:~> mkisofs -r -iso-level 4 -m .beagle -V 20060922_zhangweiwu_backup \ -m Cache -m .Trash -m .thumbnails -m music -m '*.avi' -o /tmp/zhangweiwu.iso ~ The first session of multi-session disc is made. The next day, do this: [EMAIL PROTECTED]:~> mkisofs -C `cdrecord dev=/dev/hdd -msinfo` -M /dev/hdd -old-root / \ -m .beagle -m Cache -m .Trash -m .thumbnails -m music -m '*.avi' \ -r -iso-level 4 -V 20060923_zhangweiwu_backup -o /tmp/zhangweiwu.iso ~ Then mkisofs start working, reading CDR for 10 seconds, then hang there. top(1) shows mkisofs uses 100% CPU resource. First I thought it's simply making the image, I left the computer there for 10 hours and it's still computing, then I think probably it is a bug, mkisofs should not take so long time to make the image. mkisofs only read the CDR in the beginning, then in the following hours it doesn't seems to be reading the CDR; besides, both CDR and the DVD-RW driver are new, thus I guess it's not related to CDR performance. I added two '-v' parameter to the commandline and get the attached typescript (using script(1)) for you for debugging purpose. In that typescript I used Ctrl+C to break mkisofs after 10 hours. Total number of files recorded on CDR is some 1000 files. Please let me know what else should I provide to help you get the bug tracked/reproduced. for me it is always reproducible. 在 2006-09-17日的 15:19 +0800,张韡武写道: > Hello.
