Bug Maintainence with GNATS
This page consists primarily of instructions for the
SLD maintainers
describing how to query and edit records in the GNATS datadase.
When a maitainer recieves notification of a bug from a user, via email,
the basic steps to follow are:
- Collect all information regarding fixes to the problem or if
none are available possible work arounds.
- login to unixhub.slac.stanford.edu and invoke the program
/usr/local/gnats/bin/edit-pr ( sticking /usr/local/gnats/bin in
your path would be conveniant ) with the number of the problem
record as an argument ( this number was specified in the email
message notifying the maintainer of the problem ) The use of
edit-pr is described in detail below.
- use the information collected in step 1 to update the
problem record and notify the problem submitter of the changes.
Maintainers may
query
the Gnats database directly via WWW
or they may use the program /usr/local/gnats/bin/query-pr
described below
to query the database and generate reports on problems in various
states (e.g open, analyzed, closed etc.)
Using edit-pr to edit existing Problem Reports
Use edit-pr to make changes to existing PRs in the database.
edit-pr is both a shell script and a Lisp program for gnu
Emacs. Both implementations are essentially identical, though the Emacs
interface provides interactive prompting for some of the fields.
edit-pr first examines the PR you wish to edit and locks it if it
is not already locked. This is to prevent you from editing a PR at the
same time as another user. If the PR you wish to edit is already in the
process of being edited, edit-pr tells you the name of the person
who owns the lock.
You may edit any field in the database that you wish. We recommend that
you avoid deleting any information in the Text and MultiText
fields (such as `>Description:' and `>How-To-Repeat:')
. We also recommend that you
record the final solution to the problem in the `>Fix:' field for
future reference.
If you change the `>Responsible:' field, edit-pr prompts you
to supply a reason for the change. edit-pr then mails copies of
the change message to the previous responsible party, and to the new
responsible party. The change is then recorded in the
`>Audit-Trail:' section of the PR as follows:
- Responsible-Changed-From-To: The value change, supplied
- automatically by edit-pr.
- Responsible-Changed-By: Your name here, supplied
- automatically by edit-pr.
- Responsible-Changed-When: The current date, supplied
- automatically by edit-pr.
- Responsible-Changed-Why: Your reason for the change; you
- are prompted for this.
If you change the `>State:' field, you are prompted to supply a
reason for the change. Copies of the change message are then mailed to
the responsible party, and to the original submitter of the Problem
Report. The change is then recorded in the `Audit-Trail' section
of the PR as follows:
- State-Changed-From-To: The value change, supplied
- automatically by edit-pr.
- State-Changed-By: Your name here, supplied
- automatically by edit-pr.
- State-Changed-When: The current date, supplied
- automatically by edit-pr.
- State-Changed-Why: Your reason for the change; you are
- prompted for this.
The PR is then resubmitted to the database, and the index is updated.
IMPORTANT NOTE FOR SLD MAINTAINERS: Due to the buggy version of the
Unix mail program Sendmail currently in use on the Unix mail server
unixhub, you are required to DELETE THE LINE
Reply-To: Mwww@unixhub.slac.stanford.edu
from the problem record the first time you edit it. After having deleted
this line, replace it with the line that occurs later in the record and
looks like:
Reply-To: email_adress@some_site.some_domain.edu
where email_adress@some_site.some_domain.edu is the proper email
adress of the submitter of the bug report. This will insure that the submitter
is notified of any progress that is made in solving the problem. This step
will hopefully be eliminated when the new version of Sendmail is installed on
unixhub
Invoking edit-pr
The usage for edit-pr is:
edit-pr gnats-id [ -V | --version ] [ -h | --help ]
To invoke edit-pr at SLAC, on a Sun use /usr/local/gnats/bin/edit-pr
and on an RS/6000 use /usr/local/gnats/aix/bin/edit-pr.
You must first determine which PR you want to edit. The options are:
- -V or --version
- Prints the version number edit-pr.
- -h or --help
- Prints the usage for edit-pr.
edit-pr calls the editor specified in your environment
variable EDITOR on a temporary copy of that PR. (If you don't
have the variable EDITOR defined in your environment, the default
editor vi is used. To set the EDITOR environment variable from
the shell issue the command: setenv EDITOR editor e.g. if
you wanted to use xedit as your editor on unixhub you would issue the
command setenv EDITOR /usr/local/X11R5/bin/xedit)
Edit the PR, changing any relevant fields or adding to existing
information. When you exit the editor, edit-pr prompts you on
standard input for a reason if you've changed either the
`>Responsible:' field or the '>State:' field. edit-pr
tracks the information you provide when changing either of these two
fields, along with the change that occurred, your name, and the time of
change in the `>Audit-Trail:' field.
Using query-pr to query the database
Obtain information from the database by using the program
query-pr. query-pr uses search parameters you provide
to find matching Problem Reports in the database. You can invoke
query-pr from the Unix shell or from within Emacs. query-pr
uses the same arguments whether it is invoked from the shell or from
Emacs.
All arguments and options to query-pr are optional. If you do
not specify a PR identification number and do not give any search
parameters, query-pr displays the entire database. All arguments
are considered identification numbers of Problem Reports to display.
Any number of options can be given (though some make no sense when
specified on the same command line); all are connected with a logical
AND.
Invoking query-pr
From the Unix shell, simply type query-pr (or if
you have not set your path variable /usr/local/gnats/bin/query-pr)
, followed by any search
parameters you wish to exercise. From Emacs type M-x query-pr.
query-pr prompts you for search parameters in the
minibuffer.
query-pr can also be accessed by electronic mail.
To use this feature, simply send
mail to the address `query-pr@unixhub.slac.stanford.edu' with command
line arguments or options in the 'Subject:' line of the mail
header. GNATS replies to your mail with the results of your query.
The default settings for the query-pr mail server are
- --restricted --state="open|analyzed|feedback|suspended"
To override the `--state' parameter, specify
`--state=state' in the Subject: line of the mail
header.
The usage for query-pr is:
- query-pr [ gnats-id ]
- [ -c category | --category=category ]
- [ -s state | --state=state ]
- [ -r responsible | --responsible=responsible ]
- [ -S submitter | --submitter=submitter ]
- [ -e severity | --severity=severity ]
- [ -p priority | --priority=priority} ]
- [ -O originator | --originator=originator ]
- [ -t text} | --text=text ]
- [ -m text | --multitext=text ]
- [ -R | --restricted ]
- [ -F | --full ] [ -q | --summary ] [ -i | --sql ]
- [ -P | --print-path ]
- [ -d directory | --directorydirectory ]
- [ -o outfile | --outputoutfile ]
- [ -V | --version ] [ -h | --help ]
If you run query-pr from within Emacs, you can use
C-x or, M-x next-error
to scroll through Problem Reports one by one after the search is
finished.
Search criteria
The following arguments and options specify search criteria. The lack
of a criterion indicates that all values for the corresponding field are
valid for the search.
Using an argument to query-pr specifies the most stringent search
criteria, that of a single PR.
- gnats-id
- The identification number of the PR you wish to view, as shown in the
`>Number:' field. Any number of gnats-id arguments may be
given.
- -c category
- --category=category
- Search only for PRs with a `>Category:' value of category.
For a list of valid categories, type `send-pr -L' from the
shell.
- -s state
- --state=state
- Search only for PRs with a `>State:' value of state.
state must be one of: `open', `analyzed',
`feedback', `closed', or `suspended'.
- -rresponsible
- --responsibleresponsible
- Search only for PRs with a `>Responsible:' value of responsible.
- -Ssubmitter
- --submittersubmitter
- Search only for PRs with a `>Submitter:' value of submitter.
- -e severity
- --severity=severity
- Search only for PRs with a `>Severity:' value of severity.
severity must be one of: `critical', `serious', or
'non-critical'.
- -ppriority
- --priority=priority
- Search only for PRs with a `>Priority:' value of priority.
priority must be one of: `high', `medium', or
`low'.
- -Ooriginator
- --originator=originator
- Search only for PRs with an `>Originator:' value of originator.
Since this option does not reference the index, queries using it finish
much faster if you also use another search criterion that is part
of the index.
- -t text
- --text=text
- Search the `Text' fields in the database for the regular expression
text. Text fields include the following (the
`>' and `:' Problem Report fieldname delimiters have been
removed for the sake of brevity and readability):
- Submitter-Id Originator Synopsis
- Category Release Responsible
- Arrival-Date
- Queries using this option can be slow. Since this option does not
reference the index, queries using it finish much faster if you also use
another search criterion that is part of the index.
- -m text
- --multitext=text
- Search the MultiText fields in the database for the regular
expression text. MultiText fields include the following
(again, the fieldname delimiters `>' and `:' have been
omitted):
- Organization Environment Description
- How-To-Repeat Fix Audit-Trail
- Unformatted
