14 @cindex troubleshooting
16 Occasionally you may encounter a bug in @pspp{}.
18 If you believe you have found a bug, please
19 make sure that it really is a bug. Sometimes, what may appear
20 to be a bug, turns out to be a misunderstanding of how to use the program.
21 If you are unsure, ask for advice on the pspp-users mailing list.
22 Information about the mailing list is at @uref{http://lists.gnu.org/mailman/listinfo/pspp-users}.
24 It is also valuable to try the newest version of @pspp{}, since the
25 problem may have already been fixed. You can always find the newest
26 version of PSPP by visiting @url{https://www.gnu.org/s/pspp, the PSPP
27 website}. You might have obtained PSPP from a downstream packager,
28 such as a GNU/Linux distribution; if your downstream package is not
29 up-to-date, please ask the distributor to update to the newest
32 If the problem persists in the up-to-date version, check to see if it
33 has already been reported. Reported issues are listed at
34 @uref{http://savannah.gnu.org/bugs/?group=pspp}. If it has already
35 been reported, you might consider adding a comment with additional
36 information or even just to mention that you are also experiencing the
37 problem, since the PSPP developers are often inclined to work on
38 issues that are important to a large number of users.
40 For known issues in individual language features, see the relevant section in @pxref{Language}.
42 If the problem exists in a recent version and it has not already
43 been reported, then please report it.
46 @section How to report bugs
48 The best way to send a bug report is using the web page at
49 @uref{http://savannah.gnu.org/bugs/?group=pspp}.
50 Alternatively, bug reports may be sent by email
51 to @email{bug-gnu-pspp@@gnu.org}.
53 A high-quality bug report allows the developers to understand,
54 reproduce, and ultimately fix the problem. We recommend
55 including the following:
57 @item The version of @pspp{} in which you encountered the problem
58 That means the precise version number. ``The latest version''
59 is often too ambiguous because
60 releases happen quickly, and bug reports are archived indefinitely.
61 @item The operating system and type of computer on which it is running.
62 @item A sample of the syntax which causes the problem or, if it is a user
63 interface problem, the sequence of steps required to reproduce it.
64 Screenshots can be helpful for reporting bugs in the graphical user
65 interface, especially since GUI bugs can arise on some systems but
66 not others, but they do not usually help fixing other kinds of bugs.
67 @item A description of what you think is wrong: What happened that you
68 didn't expect, and what did you expect to happen?
71 Here is one example of a bug report that includes all of the elements above:
75 When I run PSPP 0.8.4 on my GNU/Linux system, executing the following
90 but I think the output should be:
98 The following bug report, on the other hand, does not provide enough
99 information for PSPP developers to understand the problem. This means
100 that the developers cannot identify or fix the problem without
101 additional rounds of questions, which is more work for both the
102 reporter and the developer:
106 I downloaded the latest version of PSPP and entered a sequence of numbers,
107 but when I analyse them it gives the wrong output.
111 @pspp{} developers value all users' feedback, but cannot promise
112 an immediate response. The bug reporting is not a consultancy or
113 support service, although you can make private arrangements for such
114 services. Since @pspp{} is free software, consultants have access to
115 the information they need to provide such support.
117 For general enquiries or help, please use the
118 @uref{http://lists.gnu.org/mailman/listinfo/pspp-users, pspp-users
119 mailing list} instead of the bug mailing list or bug tracker.
121 The PSPP bug tracker and bug reporting mailing list are public. To
122 privately report a security vulnerability in GNU PSPP, please send
123 your report to the closed mailing list @email{pspp-security@@gnu.org}.
124 The PSPP developers will help you assess your report and fix problems
125 prior to public disclosure.
