I replaced `sysutils/cdrtools` (ver 3.01) with `sysutils/cdrtools-devel` (ver 3.02 alpha7) and it works just fine now. This could be a bug that appears in 3.01 but got fixed in the newest devel version. More investigation is needed. It's interesting that since cdrtools 3.02 stays alpha, cdrtools-devel stays devel (for years, long overdue). And by default, FreeBSD comes with the older stable version. https://sourceforge.net/projects/cdrtools/files/alpha/ http://www.freshports.org/sysutils/cdrtools-devel/ Created attachment 184636 [details]
Patch for sysutils/cdrtools integrating official isoinfo and mkisofs fixes
(In reply to Guangyuan (Charlie) Yang from comment #1) Well, FreeBSD ports just mirror the upstream release policy and sysutils/cdrtools in fact is at the current stable version 3.01. I've noticed that an official patch was released for isoinfo and mkisofs in cdtrools 3.01 which adds directory loop recognition in order to prevent from an endless loops that in turn may consume all available memory, though. Please give the patch in Bugzilla attachment #184636 [details] a try, which integrates said fix into the sysutils/cdrtools port. However, I can't tell whether that will solve your problem as your test1.iso from attachment #184520 [details] doesn't cause the isoinfo of the sock cdrtools 3.01 to segfault here. If that patch doesn't make a difference, I'll just close this PR, though, as this problem isn't really specific to FreeBSD or FreeBSD ports and sysutils/py-diffoscope should just consider using sysutils/cdrtools-devel for testing then. (In reply to Marius Strobl from comment #3) Thanks! So the image I uploaded works fine on your system with cdrtools 3.01? Anyway, will try the patch and let you know. (In reply to Marius Strobl from comment #3) Probably a newbie question, but how do I apply the patch? It seems to be a diff of Makefile and diskinfo, but not the actual code. As a point of reference a number of OS distributions ship cdrtools 3.02 alpha 7 as their cdrtools package -- https://repology.org/metapackage/cdrtools/versions Of course this doesn't necessarily mean that FreeBSD should also do this; I point it out only to demonstrate that others have apparently had to find ways around upstream's lethargic release schedule. (In reply to Marius Strobl from comment #3) Applying the patch you provided fixes the problem. However, I found something interesting in the patched version of cdrtools 3.01: # isoinfo --version isoinfo 3.02a02 (amd64-unknown-freebsd12.0) Copyright (C) 1993-1999 Eric Youngdale (C) 1999-2015 Joerg Schilling (In reply to Guangyuan (Charlie) Yang from comment #7) Yes, that's more or less expected; apparently, the patch for 3.01 was generated based on a 3.02 alpha version, but only the version string of mkisofs adjusted accordingly and that of isoinfo forgotten. (In reply to Marius Strobl from comment #8) If that's just a version number issue, do you think we can apply this patch to sysutils/cdrtools then? (Or it's already been applied?) I am working on solving sysutils/py-diffoscope test cases (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220870) and some of the errors come from this bug. A commit references this bug: Author: marius Date: Tue Jul 25 20:11:28 UTC 2017 New revision: 446622 URL: https://svnweb.freebsd.org/changeset/ports/446622 Log: Integrate an official patch for isoinfo and mkisofs which adds directory loop recognition in order to prevent from an endless loops that in turn may consume all available memory. PR: 220868 Changes: head/sysutils/cdrtools/Makefile head/sysutils/cdrtools/distinfo (In reply to Guangyuan (Charlie) Yang from comment #9) The cdrtools source regularly suffers from issues such as fuckups in version numbers, unexpanded license boiler plates etc. so I saw no reason for not integrating that patch. (In reply to Marius Strobl from comment #11) Haha, thanks! |
Created attachment 184520 [details] The image that fails isoinfo isoinfo works fine on other images but fails on this particular image (from the diffoscope test suite). Can confirm that it works fine with this image on Arch Linux. # isoinfo -l -i test1.iso Setting input-charset to 'UTF-8' from locale.
