Debbugs is a bugtracking system (BTS) that was initially written for the Debian project but currently used also by the GNU project. The main distinctive feature of Debbugs is that it’s mostly email-based. All actions on bug reports: opening, closing, changing the status, commenting, forwarding are performed via email by sending specially composed letters to the particular mail addresses. However, searching the bug reports, querying bug report status and viewing comments have been web-based for a long time. To overcome this inconvenience the Debbugs/SOAP service was introduced.
The Debbugs/SOAP service provides the means for developers to write client applications that can send the queries with certain search criteria to the Debbugs server and retrieve a set of bug reports that match them. The developer may also ask the Debbugs server for additional information about every bug report (e.g. subject, date, originator, tags and etc.) and get all comments and attachments.
debbugs
, described in this document, is the Emacs library that
exposes to developers the available functions provided by the Debbugs
server. debbugs
uses Emacs’ SOAP client library for
communication with the Debbugs server. In tandem with Emacs’ email
facilities, debbugs
provides a solution for building
applications that interact with the Debbugs BTS directly from Emacs
without addressing Debbugs’ web interface.
The user interface for accessing the Debbugs server for GNU projects is described in (debbugs-ug)Debbugs User Guide.
Next: Configuration, Previous: Debbugs Programmer’s Manual, Up: Debbugs Programmer’s Manual [Contents]
Install debbugs
from the (elisp)ELPA repository.
If you want to install debbugs
on Emacs 22/23, you will need to
install the soap-client
library first. It can be downloaded from
the Emacs SOAP client
project page.
Compile the library and add it into your load-path
:
(add-to-list 'load-path "/path/to/emacs-soap-client/")
debbugs
library can be downloaded from the
ELPA repository. Compile it and
set the load-path
:
(add-to-list 'load-path "/path/to/debbugs/")
We have not tried yet to install debbugs
on Emacs 21. We would
definitely say that the installation will require even more additional
libraries than needed for installation on Emacs 22/23.
Next: Requesting bug numbers, Previous: Installation, Up: Debbugs Programmer’s Manual [Contents]
debbugs
is already configured to work with two main ports of
Debbugs BTS: https://bugs.debian.org and
https://debbugs.gnu.org. So if you intend to use one of these
ports, you don’t need to configure debbugs
. If you want to
interact with a Debbugs port other than those listed, you have to
configure debbugs
by adding a new server specifier to the
debbugs-servers
user option. The actual port can be selected
by the debbugs-port
user option.
List of Debbugs server specifiers. Each entry is a list that contains a
string identifying the port name and the server parameters in
keyword-value form. The list initially contains two predefined and
configured Debbugs servers: "gnu.org"
and "debian.org"
.
Valid keywords are:
:wsdl
Location of WSDL. The value is a string with the URL that should return the WSDL specification of the Debbugs/SOAP service. This keyword is intended for future use, it is ignored currently.
:bugreport-url
The URL of the server script (bugreport.cgi
in the default
Debbugs installation) that provides the access to mboxes with messages
from bug reports.
Example. Add a new Debbugs port with name "foobars.net":
(add-to-list 'debbugs-servers '("foobars.net" :wsdl "https://bugs.foobars.net/cgi/soap.cgi?WSDL" :bugreport-url "https://bugs.foobars.net/cgi/bugreport.cgi"))
This user option holds the name of the currently used port. The value
of the user option corresponds to the Debbugs server to be accessed,
either "gnu.org"
or "debian.org"
, or a user defined port
name.
The function debbugs-get-status
(see Requesting bugs statuses) caches retrieved status entries in order to improve the
performance. This user option determines the number of seconds an
entry is cached, before it is retrieved again. A value of nil
disables cache expiration, and a value of t
disables caching.
Both values are not recommended for a usual workflow.
If this user option is non-nil
, there is a progress report when
retrieving bugs.
Next: Requesting bugs statuses, Previous: Configuration, Up: Debbugs Programmer’s Manual [Contents]
In Debbugs BTS, the bug number is the unique identifier of a bug report. The functions described in this section return from the Debbugs server the list of bug numbers that match a user’s query.
This function returns a list of bug numbers that match the query. query is a sequence of keyword-value pairs where the values are strings, i.e. :KEYWORD “VALUE” [:KEYWORD “VALUE”]*
The keyword-value pair is a subquery. The keywords are allowed to have multiple occurrence within the query at any place. The subqueries with the same keyword form the logical subquery, which returns the union of bugs of every subquery it contains.
The result of the query is an intersection of results of all subqueries.
Valid keywords are:
:package
The value is the name of the package a bug belongs to, like "emacs"
,
"coreutils"
, "gnus"
, or "tramp"
.
:src
This is used to retrieve bugs that belong to source with given name.
:severity
This is the severity of the bug. The exact set of available severities depends on the policy of a particular Debbugs port:
Debian port:
"critical"
, "grave"
, "serious"
,
"important"
, "normal"
, "minor"
, "wishlist"
,
and "fixed"
.
GNU port:
"serious"
, "important"
, "normal"
, "minor"
,
"wishlist"
.
:tag
An arbitrary string the bug is annotated with. Usually, this is used to mark the status of the bug. The list of possible tags depends on the Debbugs port.
Debian port: "patch"
, "wontfix"
, "moreinfo"
,
"unreproducible"
, "fixed"
, "potato"
,
"woody"
, "sid"
, "help"

, "fixed-upstream"
,
"l10n"
, "etch"
, "etch-ignore"
, "lenny"

"wheezy"
, "wheezy-ignore"
, "jessie"
,
"jessie-ignore"
, "stretch"
, "stretch-ignore"
,

, "moreinfo"
, "patch"
,
"pending"
, "help"
, "security"
,
"confirmed"
, "easy"
. See
https://debbugs.gnu.org/Developer.html#tags for the actual list
of tags.
:owner
This is used to identify bugs by the owner’s email address. The
special email address "me"
is used as pattern, replaced with
the variable user-mail-address
(see (elisp)User
Identification).
:submitter
With this keyword it is possible to filter bugs by the submitter’s
email address. The special email address "me"
is used as
pattern, replaced with the variable user-mail-address
.
:maint
This is used to find bugs of the packages which are maintained by the
person with the given email address. The special email address
"me"
is used as pattern, replaced with user-mail-address
.
:correspondent
This allows to find bug reports where the person with the given email
address has participated. The special email address "me"
is used
as pattern, replaced with user-mail-address
.
:affects
With this keyword it is possible to find bugs which affect the package
with the given name. The bugs are chosen by the value of field
affects
in bug’s status. The returned bugs do not necessary
belong to this package.
:status
Status of bug. Valid values are "open"
, "forwarded"
and
"done"
.
:archive
A keyword to filter for bugs which are already archived, or not. Valid
values are "0"
(not archived), "1"
(archived) or
"both"
. If this keyword is not given in the query,
:archive "0"
is assumed by default.
Example. Get all opened and forwarded release critical bugs for the
packages which are maintained by "me"
and which have a patch:
(let ((debbugs-port "debian.org")) (debbugs-get-bugs :maint "me" :tag "patch" :severity "critical" :status "open" :severity "grave" :status "forwarded" :severity "serious"))
This function returns a list of bug numbers, according to amount (a number) of latest bugs.
Example. Get the latest six bug report numbers from Debian BTS:
(let ((debbugs-port "debian.org")) (debbugs-newest-bugs 6)) ⇒ (633152 633153 633154 633155 633156 633157)

The Debbugs servers include an hyperestraier search engine, which allows to search inside the bug database. This is enabled only for the GNU port of the BTS, and also only the GNU port offers a Debbugs/SOAP interface for access.
The search engine uses an index over the bug database. This index is refreshed once a day only; search hits do not include recent changes of the same day.
Return the result of a full text search according to query.
query is a sequence of lists of keyword-value pairs where the values are strings or numbers, i.e. :keyword value [:keyword value]*
Every sublist of the query forms a hyperestraier condition. A detailed description of hyperestraier conditions can be found at https://dbmx.net/hyperestraier/uguide-en.html#searchcond.
The following conditions are possible:
The string search-phrase forms the search on the database. It contains words to be searched for, combined by operators like AND, ANDNOT and OR. If there is no operator between the words, AND is used by default. The phrase keyword and value can also be omitted, this is useful in combination with other conditions.
:skip
and :max
are optional. They specify, how many
hits are skipped, and how many maximal hits are returned. This can be
used for paged results. Per default, :skip is 0 and all possible hits
are returned according to the default maximum of the debbugs server.
There is also an absolute maximum how many hits are returned by the
debbugs server, which cannot be overwritten my any larger :max
number.
There must be exactly one such condition.
attribute is one of the following keywords:
:subject
:@title
The subject of a message or the title of the bug, a string.
:date
:@cdate
The submission date of the bug or the modification date of a message, a number.
:@author
The email address of the author of a message belonging to this bug, a
string. It may be different than the email of the person submitting
the bug. The special email address "me"
is used as pattern,
replaced with user-mail-address
.
:package
The value is the name of the package a bug belongs to, like
"emacs"
, "coreutils"
, "gnus"
, or "tramp"
.
:tags
An arbitrary string the bug is annotated with.
:severity
This is the severity of the bug. The exact set of allowed values
depends on the Debbugs port. Examples are "normal"
,
"minor"
, "wishlist"
etc.
:operator
defines the comparison operator to be applied to
attribute. For string attributes this could be "STREQ"
(is equal to the string), "STRNE"
(is not equal to the string),
"STRINC"
(includes the string), "STRBW"
(begins with the
string), "STREW"
(ends with the string), "STRAND"
(includes all tokens in the string), "STROR"
(includes at least
one token in the string), "STROREQ"
(is equal to at least one
token in the string) or "STRRX"
(matches regular expressions of
the string). For operators with tokens, several values for
attribute shall be used.
Numbers can be compared by the operators "NUMEQ"
(is equal to
the number), "NUMNE"
(is not equal to the number),
"NUMGT"
(is greater than the number), "NUMGE"
(is
greater than or equal to the number), "NUMLT"
(is less than the
number), "NUMLE"
(is less than or equal to the number) or
"NUMBT"
(is between the two numbers). In the last case, there
must be two values for attribute.
If an operator is led by "!"
, the meaning is inverted. If a
string operator is led by "I"
, the case of the value is
ignored.
The optional :order
can be specified only in one condition. It
means, that attribute is used for sorting the results. The
following order operators exist: "STRA"
(ascending by string),
"STRD"
(descending by string), "NUMA"
(ascending by
number) or "NUMD"
(descending by number).
A special case is an :order
, where there is no corresponding
attribute value and no operator. In this case, attribute is
not used for the search.
The result of the query is a list of association lists with the same attributes as in the conditions. Additional attributes are
id
The bug number.
msg_num
The number of the message inside the bug log.
snippet
The surrounding text found by the search. For the syntax of the snippet, consult the hyperestraier user guide.
Example. Get two messages containing words "armstrong" and "debbugs" from GNU BTS. Skip the first 10 hits:
(let ((debbugs-port "gnu.org")) (debbugs-search-est '(:phrase "armstrong AND debbugs" :skip 10 :max 2) '(:severity "normal" :operator "STRINC") '(:date :order "NUMA"))) ⇒ ((("msg_num" . 21) ("date" . 1229208302) ("@author" . "Glenn Morris <*****@gnu.org>") ("@title" . "Re: bug#1567: Mailing an archived bug") ("id" . 1567) ("severity" . "normal") ("@cdate" . "Wed, 17 Dec 2008 14:34:50 -0500") ("snippet" . "…") ("subject" . "Mailing an archived bug") ("package" . "debbugs.gnu.org")) …)
Example. Show all messages for package "emacs" on GNU BTS between 2011-08-21 and 2011-08-31.
(let ((debbugs-port "gnu.org")) (debbugs-search-est '(:max 500) '(:package "emacs" :operator "STREQ") `(:@cdate ,(floor (float-time (encode-time 0 0 0 21 8 2011))) ,(floor (float-time (encode-time 0 0 0 31 8 2011))) :operator "NUMBT")))
Next: Requesting user tags, Previous: Searching bugs, Up: Debbugs Programmer’s Manual [Contents]
Returns a list of messages related to bug-number. Every message is an association list with the following attributes:
msg_num
The number of the message inside the bug log. The numbers are ascending, newer messages have a higher number.
header
The header lines from the E-mail messages, as arrived at the bug tracker.
body
The message body.
attachments
A list of possible attachments, or nil
. Not implemented yet server
side.
Returns the message numbers of messages. messages must be
the result of a debbugs-get-bug-log
call.
Example. Get message numbers from bug report #456789 log from Debian BTS:
(let ((debbugs-port "debian.org")) (debbugs-get-message-numbers (debbugs-get-bug-log 456789))) ⇒ (5 10 12)
Returns the message message-number of
messages. messages must be the result of a
debbugs-get-bug-log
call. The returned message is a list of
strings. The first element are the header lines of the message, the
second element is the body of the message. Further elements of the list,
if any, are attachments of the message. If there is no message with
message-number, the function returns nil
.
Example: Return the first message of the last submitted bug report to GNU BTS:
(let* ((debbugs-port "gnu.org") (messages (apply 'debbugs-get-bug-log (debbugs-newest-bugs 1)))) (debbugs-get-message messages (car (debbugs-get-message-numbers messages))))
Download mbox with all messages from bug report bug-number. mbox-type specifies a type of mbox and can be one of the following symbols:
mboxfolder
Download mbox folder, i.e. mbox with messages as they arrived at the Debbugs server.
mboxmaint
Download maintainer’s mbox, i.e. mbox with messages as they are resent from the Debbugs server.
mboxstat
mboxstatus
Download status mbox. The use of either symbol depends on the actual
Debbugs server configuration. For "gnu.org"
, use the former;
for "debian.org"
- the latter.
filename, if non-nil
, is the name of the file to store
mbox. If filename is nil
, the downloaded mbox is
inserted into the current buffer.
Note, that mbox downloading will work only if the
:bugreport-url
field of the debbugs-servers
user option
is specified (see Configuration).

A user tag is a string, a user has assigned to one or several bugs.
The user is identified by an email address. The port "gnu.org"
uses also package names as user identification.
Return a list of bug numbers which match query.
query is a sequence of keyword-value pairs where the values are strings, i.e. :KEYWORD “VALUE” [:KEYWORD “VALUE”]*
Valid keywords are:
:user
The value is the name of the package a bug belongs to, like
"emacs"
, "coreutils"
, or "tramp"
. It can also be
an email address of a user who has applied a user tag. The special
email address "me"
is used as pattern, replaced with
user-mail-address
. There must be at least one such entry; it
is recommended to have exactly one.
:tag
A string applied as user tag. Often, it is a subproduct
identification, like "cedet"
or "tramp"
for the package
"emacs"
.
If there is no :tag
entry, no bug numbers will be returned but
a list of existing user tags for :user
.
Example. Get all user tags for the package "emacs"
