cdrtools (formerly known as cdrecord) is a collection of independent projects of free software/open source computer programs for CD and DVD authoring.

The project was maintained for over two decades by Jörg Schilling, who died on October 10, 2021.{{cite web|title=RIP Jörg Schilling|url=https://minnie.tuhs.org/pipermail/tuhs/2021-October/024523.html|quote=I have received message from his family that Jörg Schilling has passed away|archive-url=https://web.archive.org/web/20211013052832/https://minnie.tuhs.org/pipermail/tuhs/2021-October/024523.html|archive-date=2021-10-13}}{{Cite web|title=Fraunhofer FOKUS {{!}} IT original Jörg Schilling has passed away|url=https://www.fokus.fraunhofer.de/en/news/fokus/joerg_schilling_2021_10|access-date=2022-01-01|website=www.fokus.fraunhofer.de|archive-date=1 January 2022|archive-url=https://web.archive.org/web/20220101100900/https://www.fokus.fraunhofer.de/en/news/fokus/joerg_schilling_2021_10|url-status=dead}}

Because of some licensing issues,{{cite web|url=https://lwn.net/Articles/195167/|title=cdrtools - a tale of two licenses|website=lwn.net}} there is also a Debian fork of an older version of cdrtools called cdrkit.

Features

The most important parts of the package are cdrecord, a console-based burning program; cdda2wav, a CD audio ripper that uses libparanoia; and mkisofs, a CD/DVD/BD/UDF/HFS filesystem image creator. As these tools do not include any GUI, many graphical front-ends have been created.

The collection includes many features for CD, DVD and Blu-ray disc writing such as:

History

= Origins and name change =

The first releases of cdrtools were called cdrecord because they only included the cdrecord tool and a few companion tools, but not mkisofs nor cdda2wav. A copy of mkisofs, created in 1993 by Eric Youngdale for Yggdrasil Linux, was incorporated in 1997.{{cite web |title=Announcing mkisofs 1.13 |url=https://savannah.gnu.org/news/?group_id=10425}}{{cite web |title=CDRTOOLS = cdrecord + cdda2wav + mkisofs |url=http://www.sco.com/skunkware/cdrecord/notes.html}} In 1998, a copy of an experimental version of cdda2wav, created by Heiko Eißfeldt,{{cite web |title=Cdda2wav |url=http://www.cdda2wav.de/}} was included in the cdrecord package.{{cite web |title=cdrecord-1.8a10 (cdrtools) ready |url=https://groups.google.com/g/linux.apps.cdwrite/c/UxtzUM8UqyQ/m/8CVps88BbHAJ }}{{cite web |title=NEW features of cdrecord-1.8a6 |url=https://ftp.gwdg.de/pub/misc/cdrecord/ALPHA/OLD/1.8aX/AN-1.8a6}}

In 1999 the project started to be called cdrtools{{cite web |title=cdrtools-1.8a19 ready (cdrecord+cdda2wav+mkisofs) |url=https://groups.google.com/g/linux.apps.cdwrite/c/FkjzVMWK1w4 }}{{cite web |title=Information for build cdrtools-2.01-11.fc7 |url=https://koji.fedoraproject.org/koji/buildinfo?buildID=2185}} to better reflect the fact that it had become a collection of tools.

= DVD and Blu-ray disc writing support =

DVD writing support (cdrecord-ProDVD) in cdrecord started in early 1998, at the request of the data archivists of the European Southern Observatory.{{cite web |title=Using DVD Technology for Archiving Astronomical Data |url=https://www.eso.org/sci/publications/messenger/archive/no.93-sep98/messenger-no93-22-23.pdf |publisher=European Southern Observatory}}{{cite web |title=The Prospects of DVD-R for Storing Astronomical Archive Data |url=http://adsabs.harvard.edu/pdf/1999ASPC..172..269P7 |publisher=Astronomical Society of the Pacific - Provided by NASA Astrophysics Data System}}{{cite web |title=Using DVD Technology for Archiving Astronomical Data (cont'd) |url=http://articles.adsabs.harvard.edu/pdf/2000ASPC..216..137P |publisher=Astronomical Society of the Pacific - Provided by NASA Astrophysics Data System}}{{discuss|ASP paper}} But since the relevant information required a non-disclosure agreement and DVD writers were not publicly available, it was not included in the source code.{{cn|date=October 2021}}

In 2002, Jörg Schilling started offering free license keys to the closed-source variant cdrecord-ProDVD for educational, and research use, shortly thereafter also for private use.{{cite web |title=Re: cdrecord floating point exception |url=https://www.mail-archive.com/cdwrite@other.debian.org/msg12603.html}} Unregistered free licenses were initially limited to single-speed writing and would expire every year.{{cite web |title=cdrecord will not burn DVD ISO's |url=https://www.suse.com/support/kb/doc/?id=000016968}} On 15 May 2006, support for DVD writing was added to the open-source version 2.01.01a09 after switching the license to CDDL, thereby removing the need to get a license key.{{cite web |title=README |url=https://ftp.gwdg.de/pub/misc/cdrecord/ProDVD/README}} Blu-ray disc support was added starting 2007.{{cite web |title=Changelog |url=https://ftp.gwdg.de/pub/misc/cdrecord/ALPHA/Changelog |language=German}}

The lack of open-source DVD writing support in 2001 led to heated discussions on the mailing lists, and to a number of unofficial patches for supporting the Pioneer DVD-R A03, the first DVD writer to reach mass market, and forks of cdrecord: Mandrake shipped a version called cdrecord-dvdhack,{{cite web | url=http://www.mandriva.com/de/support/security/advisories/8.2/MDKA-2002:011-1/ | title=Support / Security / Advisories / Mandrakelinux 8.2 / MDKA-2002:011-1 / Mandriva | publisher=Mandriva | accessdate=2014-10-16 | quote=cdrecord-dvdhack-1.11-0.a31.1.1mdk.ppc.rpm}} shows that Mandrake maintained a "cdrecord-dvdhack" version. whereas Redhat had dvdrecord.{{cite web|url=http://www.nongnu.org/dvdrtools/ |title=dvdrtools - dvdrecord |accessdate=2014-04-12 |url-status=dead |archiveurl=https://web.archive.org/web/20021201160106/http://www.nongnu.org/dvdrtools/ |archivedate=1 December 2002 |df=dmy }}

= Hardware access controversy =

Unlike cdrkit and libburnia, which use device files to access the hardware, cdrtools uses a different method known as CAM (for Common Access Method),{{cite web |url=http://standards.incits.org/apps/group_public/project/details.php?project_id=260 |title=Common Access Method Transport and SCSI Interface Module |date=29 December 2011 |publisher=International Committee for Information Technology Standards |accessdate=2016-01-24 }} which is available on many operating systems, including some which lack device files or only allow the kernel to access them.

This difference has turned into a controversy: some Linux users claim that the method used by cdrtools is not appropriate, while some Linux users claim that the users of cdrtools do not need to know which method is used.{{citation needed|date=April 2018}}

In cdrtools, burning optical media (such as CDs, DVDs and Blu-rays discs) is done through the SCSI interface. Users of systems with more than one burning device need to provide a SCSI device (which is identified by a triplet of numbers, scsibus,target,lun). Users of systems with only one burning device, however, do not need to specify the SCSI device since cdrtools is able to find it. By 2002 more and more burners were using the ATAPI interface. Linux 2.6 allowed the users to detect the SCSI ID of a device from its UNIX device path (/dev/hdX) and a patch was published that made identifying the burner device for cdrecord simpler by allowing the user to specify the /dev/hdX device name (or even default to a udev managed link such as /dev/cdrw). Schilling, however, rejected this approach as well as other modifications used by Linux distributions, with the rationale that it would make the software more complex and less portable as this function was not available on other UNIX systems. Linus Torvalds states that SCSI LUNs should not be used for addressing devices on Linux,{{cite web |url=https://lkml.org/lkml/2006/3/27/129 |title=Re: [PATCH] Move SG_GET_SCSI_ID from sg to scsi |last1=Torvalds |first1=Linus |authorlink1=Linus Torvalds |date=2006-03-27 |website=LKML |access-date=2015-10-22 |quote=the SCSI ID simply doesn't make sense to [Many (most) Linux devices] and they have none. So it's _not_ a unique ID.}} because these numbers are not unique, and do not make sense for many devices anymore (many devices will report 0:0:0 fake numbers). Instead Torvalds recommends that devices be addressed via their UUID, physical connection, or an alias symlink{{cite web | url=https://lkml.org/lkml/2006/3/27/117 |title=Re: [PATCH] Move SG_GET_SCSI_ID from sg to scsi |last1=Torvalds |first1=Linus |authorlink1=Linus Torvalds |date=2006-03-27 |website=LKML |access-date=2015-10-22}} as managed by udev on Linux.

Torvalds pointed out that the ioctl's have been kept to ensure cdrecord compatibility{{cite web | url=https://lkml.org/lkml/2006/3/27/129 |title=Re: [PATCH] Move SG_GET_SCSI_ID from sg to scsi|last1=Torvalds |first1=Linus |authorlink1=Linus Torvalds |date=2006-03-27 |website=LKML |access-date=2015-10-22 | quote=it does a few ioctl's that cdrecord wanted [...] does NOT try to claim that those numbers "mean" anything [...] BUS/ID/LUN crap really doesn't make sense for the majority of devices out there.

= License compatibility controversy =

By 2004, Linux distributions were maintaining a number of unofficial changes{{snd}} such as allowing the use of /dev/hdX device names and (limited) DVD writing support{{snd}} that were rejected by Schilling,{{cite web | url = https://lwn.net/Articles/97469/ | first = Jonathan | last = Corbet | title = The value of middlemen | publisher=LWN.net | date=2004-08-11 | accessdate = 2014-04-07}} who repeatedly demanded that distributions stop shipping "bastardized and defective" versions of his "legal original software".{{cite web |url=https://lwn.net/Articles/346540/ |title=The unending story of cdrtools |last1=Corbet |first1=Jonathan |date=2009-08-12 |publisher=LWN.net |accessdate=26 February 2014}}

Starting with version 2.01.01a09 in May 2006, most code from cdrtools has been relicensed under the CDDL, while mkisofs remains licensed under the GPL.The license change took place on 15 May 2006, when cdrtools-2.01.01a09 was released. (Source: [//sourceforge.net/projects/cdrtools/files/alpha/OLD/3.00aX/AN-2.01.01a09/view AN-2.01.01a09]) This change led to an ongoing disagreement about whether distribution or use of precompiled cdrtools binaries is legally possible (the GPL permits collective works, but not derivative works; and the Makefiles used to build mkisofs are CDDL licensed). The following are one-sentence summaries of the different positions:

  • Jonathan Corbet, founder of the LWN.net news source, argued that this change makes it impossible to legally distribute cdrtools binaries, because the build system used is CDDL licensed (interpreting cdrtools as derivative work of GPL and – GPL-incompatible – CDDL code) and the GPL requires "build tools and scripts also be released under the GPL".{{cite web |url=https://lwn.net/Articles/195167/ |first=Jonathan |last=Corbet |title=cdrtools - a tale of two licenses |publisher=LWN.net |accessdate=2007-08-04}}
  • Jörg Schilling denied there was a license problem in cdrtools. In his interpretation, it consisted of independent works and thus has not mixed incompatible licenses (i.e. it is a collective work, not a derivative work). According to his interpretation, binary versions may be distributed.{{cite web | url=https://bugs.launchpad.net/ubuntu/+source/cdrtools/+bug/213215/comments/17 | date=2011-06-27 | title=Comment 17 for bug 213215 | publisher=Ubuntu bug tracking | first=Joerg | last=Schilling | quote=Nobody is violating a license for distributing cdrtools either in source or in binary form.}}
  • Fedora says the cdrtools is a "incompatible mix of the GPL and the CDDL"{{cite web|url=https://fedoraproject.org/wiki/Forbidden_items|title=Forbidden items - FedoraProject|website=fedoraproject.org}} and Schilling's opinion is a "set of unorthodox opinions on licensing which are not shared by the FSF or Red Hat Legal" and thus cdrtools is forbidden on Fedora.
  • Fedora's legals also proposed three solutions to solve license incompatibility (adding some sort of GPL linking exception, replace CDDL with GPL-compatible license, or dual-licensing CDDL/GPL{{Cite web|url=https://www.redhat.com/archives/fedora-legal-list/2009-July/msg00000.html|title=Re: [Fedora-legal-list] Legal CD/DVD/BD writing software for RedHat and Fedora|website=www.redhat.com}}) and consequently available to re-open discussion about including cdrtools.
  • As is common with the GPL and other open source licenses, very little case law exists to provide guidance to users and provide a definitive answer on whether binary versions are distributable.

As a result of this controversy:

  • Jörg Schilling continued to develop his version of cdrtools under the CDDL and GPL (mkisofs) licenses until he died in 2021, whereas the cdrkit fork has received next to no updates since Cdrkit 1.1.11, which was released in 2010.
  • Independent development efforts happen in libburnia which does not contain cdrtools source code, but includes a wrapper "cdrskin" to offer some command line compatibility with cdrecord and is available in many Linux distributions.
  • Gentoo Linux is unaffected, as the potential licensing issue only affects the distribution of precompiled binaries and this distribution compile from source code. It initially offers both versions, as well as libburnia, dropping cdrkit in 2017.{{Cite web|url=https://bugs.gentoo.org/show_bug.cgi?id=591778|title=591778 – app-cdr/cdrkit removal request|website=bugs.gentoo.org}}
  • Slackware only provided cdrtools (build script for cdrkit is available from SlackBuild.org,{{Cite web|url=https://slackbuilds.org/repository/14.2/system/cdrkit/|title=SlackBuilds.org - cdrkit|website=slackbuilds.org}} but the two packages could not co-exists); libburnia was introduced in November 2020 as needed by KDE Plasma 5.{{Cite web |url=https://mirrors.slackware.com/slackware/slackware64-current/ChangeLog.txt |title=Welcome to vtown, volkerdi's friendly takeover of alienBOB's ktown Plasma 5 packages - testing/packages/vtown/deps/libburn-1.5.2.pl01-x86_64-1_vtown_1.txz: Added.}}

= Inclusion into toolset Schily-Tools =

Cdrtools are part of Jörg Schilling's toolset Schily-Tools, which was originally distributed on SourceForge."The official Shily-Tools project website:" http://schilytools.sourceforge.net/

Schilling stopped updating the cdrtools-only alpha and stable branch in 2017 with version 3.02a9;{{Cite web|url=https://sourceforge.net/projects/cdrtools/files/alpha/README/view|title=cdrecord | Release notes for cdrecord at SourceForge.net|website=sourceforge.net}} version 3.02a10 and higher are only included in the source package schilytools.

The "Schily" Tool Box is a set of tools written or managed by Jörg Schilling. It includes the programs cdrecord, cdda2wav, readcd, mkisofs, smake, bsh, btcflash, calc, calltree, change, compare, count, devdump, dmake based on SunPro Make, hdump, isodebug, isodump, isoinfo, isovfy, label, mt, obosh, od, p, POSIX patch, pbosh, sccs, scgcheck, scpio, sdd, sfind, sformat, smake, sh/bosh (Bourne sh), star, star_sym, strar, suntar, gnutar, tartest, termcap, and ved.

The final version of Schily-Tools published by Jörg Schilling himself is the 2021-09-18 release.{{cite web|url=https://sourceforge.net/projects/schilytools/files/|title=Schily Tools: Browse files}}

After his death, development of Schily-Tools has been taken up by a group of volunteers. Instead of hosting it on SourceForge, it is hosted on a-not-for-profit platform, Codeberg. To mark his passing, his cdrtools final version, 3.02a10 (where the a indicates the software is semantically alpha) was declared to be the new stable version 3.02 with no substantial changes.{{cite web |url=https://codeberg.org/schilytools/schilytools/commit/e44f804bf0d3c932a8f99de54cb06370655ff913 |title=cdrecord: bump version to 3.02 |last=Clausecker |first=Robert |date=2022-08-18 |website=codeberg.org|publisher=The schilytools project |access-date=2022-10-16}}
