24 deb-changes - Debian changes file format
28 I<filename>B<.changes>
32 Each Debian upload is composed of a .changes control file, which
33 contains a number of fields in L<deb822(5)> format.
35 Each field begins with a tag, such as
39 (case insensitive), followed by a colon, and the body of the field
40 (case sensitive unless stated otherwise).
41 Fields are delimited only by field tags.
42 In other words, field text may be multiple lines in length, but the
43 installation tools will generally join lines when processing the body
44 of the field (except in case of the multiline fields
45 B<Description>, B<Changes>, B<Files>, B<Checksums-Sha1>
50 The control data might be enclosed in an OpenPGP ASCII Armored signature,
51 as specified in RFC4880.
57 =item B<Format:> I<format-version> (required)
59 The value of this field declares the format version of the file.
60 The syntax of the field value is a version number with a major and minor
62 Backward incompatible changes to the format will bump the major version,
63 and backward compatible changes (such as field additions) will bump the
65 The current format version is B<1.8>.
67 =item B<Date:> I<release-date> (required)
69 The date the package was built or last edited.
70 It must be in the same format as the date in a B<deb-changelog>(5)
73 The value of this field is usually extracted from the I<debian/changelog>
76 =item B<Source:> I<source-name> [B<(>I<source-version>B<)>] (required)
78 The name of the source package.
79 If the source version differs from the binary version, then the
80 I<source-name> will be followed by a I<source-version> in parenthesis.
81 This can happen when the upload is a binary-only non-maintainer upload.
83 =item B<Binary:> I<binary-package-list> (required in context)
85 This folded field is a space-separated list of binary packages to upload.
86 If the upload is source-only, then the field is omitted (since dpkg 1.19.3).
88 =item B<Architecture:> I<arch-list>
90 Lists the architectures of the files currently being uploaded.
91 Common architectures are B<amd64>, B<armel>, B<i386>, etc.
92 Note that the B<all> value is meant for packages that are architecture
94 If the source for the package is also being uploaded, the special entry
95 B<source> is also present.
96 Architecture wildcards must never be present in the list.
98 =item B<Version:> I<version-string> (required)
100 Typically, this is the original package's version number in whatever form
101 the program's author uses.
102 It may also include a Debian revision number (for non-native packages).
103 The exact format and sorting algorithm are described in
106 =item B<Distribution:> I<distribution>s (required)
108 Lists one or more space-separated distributions where this version should
109 be installed when it is uploaded to the archive.
111 =item B<Urgency:> I<urgency> (recommended)
113 The urgency of the upload.
114 The currently known values, in increasing order of urgency, are:
115 B<low>, B<medium>, B<high>, B<critical> and B<emergency>.
117 =item B<Maintainer:> I<fullname-email> (required)
119 Should be in the format “Joe Bloggs E<lt>jbloggs@example.orgE<gt>”, and is
120 typically the person who created the package, as opposed to the author of
121 the software that was packaged.
123 =item B<Changed-By:> I<fullname-email>
125 Should be in the format “Joe Bloggs E<lt>jbloggs@example.orgE<gt>”, and is
126 typically the person who prepared the package changes for this release.
128 =item B<Description:> (recommended)
130 =item S< >I<binary-package-name> B<-> I<binary-package-summary>
132 This multiline field contains a list of binary package names followed by
133 a space, a dash (‘B<->’) and their possibly truncated short
135 If the upload is source-only, then the field is omitted (since dpkg 1.19.3).
137 =item B<Closes:> I<bug-number-list>
139 A space-separated list of bug report numbers for bug reports that have been
140 resolved with this upload.
141 The distribution archive software might use this field to automatically
142 close the referred bug numbers in the distribution bug tracking system.
144 =item B<Binary-Only: yes>
146 This field denotes that the upload is a binary-only non-maintainer build.
147 It originates from the B<binary-only=yes> key/value from the changelog
150 =item B<Built-For-Profiles:> I<profile-list>
152 This field specifies a whitespace separated list of build profiles that
153 this upload was built with.
155 =item B<Changes:> (required)
157 =item S< >I<changelog-entries>
159 This multiline field contains the concatenated text of all changelog
160 entries that are part of the upload.
161 To make this a valid multiline field empty lines are replaced with a
162 single full stop (‘.’) and all lines are indented by one space
164 The exact content depends on the changelog format.
166 =item B<Files:> (required)
168 =item S< >I<md5sum> I<size> I<section> I<priority> I<filename>
170 This multiline field contains a list of files with an md5sum, size, section
171 and priority for each one.
173 The first line of the field value (the part on the same line as the field
174 name followed by a colon) is always empty.
175 The content of the field is expressed as continuation lines, one line per file.
176 Each line consists of space-separated entries describing the file:
177 the md5sum, the file size, the file section, the file priority, and
180 This field lists all files that make up the upload.
181 The list of files in this field must match the list of files in the
182 other related B<Checksums> fields.
184 =item B<Checksums-Sha1:> (required)
186 =item B<Checksums-Sha256:> (required)
188 =item S< >I<checksum> I<size> I<filename>
190 These multiline fields contain a list of files with a checksum and size
192 These fields have the same syntax and differ only in the checksum algorithm
193 used: SHA-1 for B<Checksums-Sha1> and SHA-256 for B<Checksums-Sha256>.
195 The first line of the field value (the part on the same line as the field
196 name followed by a colon) is always empty.
197 The content of the field is expressed as continuation lines, one line per file.
198 Each line consists of space-separated entries describing the file:
199 the checksum, the file size, and the file name.
201 These fields list all files that make up the upload.
202 The list of files in these fields must match the list of files in the
203 B<Files> field and the other related B<Checksums> fields.
209 The B<Files> field is inconsistent with the other B<Checksums> fields.
210 The B<Changed-By> and B<Maintainer> fields have confusing names.
211 The B<Distribution> field contains information about what is commonly
212 referred to as a suite.
