4 There are two ways for you to make a bug report. One uses a simple perl
5 script, and is recommended if you don't want to spend a lot of time
6 producing the report. It is designed for use by just about anyone, from
7 the newest of newbies to advanced developers. You can also make a bug
8 report the hard way -- advanced developers will probably prefer this.
11 1) Your computer *must* have perl on it for this method to work. To
12 find out if you have perl, run:
14 If it returns something like "/usr/bin/perl", you're in business.
15 Otherwise, skip on down to "The Hard Way".
16 If you aren't sure, just keep on going. When you try to run the script, it
17 will become *very* apparent if you don't have perl.
19 2) Change directory to <dirs to wine>/tools
21 3) Type in "./bug_report.pl" and follow the directions.
23 4) Post a message to the comp.emulators.ms-windows.wine newsgroup with the
24 "Nice Formatted Report" attatched. If possible, upload the full debug
25 output to a web/ftp server and provide the address in your message.
30 Some simple advice on making your bug report more useful (and thus more
31 likely to get answered and fixed):
33 1) Post as much information as possible.
35 This means we need more information than a simple
36 "MS Word crashes whenever I run it. Do you know why?"
37 Include at least the following information:
39 - Version of Wine you're using (run 'wine -v')
40 - Operating system you're using, what distribution (if any), and what
42 - Compiler and version (run 'gcc -v')
43 - Windows version, if installed
44 - Program you're trying to run, its version number, and a URL for
45 where the program can be obtained (if available)
46 - Command line you used to start wine
47 - Any other information you think may be relevant or helpful, such as
48 X server version in case of X problems, libc version etc.
50 2) Re-run the program with the -debugmsg +relay option
51 (i.e., 'wine -debugmsg +relay sol.exe').
53 If Wine crashes while running your program, it is important that we
54 have this information to have a chance at figuring out what is causing
55 the crash. This can put out quite a lot (several MB) of information,
56 though, so it's best to output it to a file. When the Wine-dbg> prompt
59 You might want to try +relay,+snoop instead of +relay, but please note
60 that +snoop is pretty unstable and often will crash earlier than a
62 If this is the case, then please use *only* +relay !!
63 A bug report with a crash in +snoop code is useless in most cases !
65 To get the trace output, use the following commands:
68 echo quit|wine -debugmsg +relay [other_options] program_name >& filename.out; tail -n 100 filename.out > report_file
69 (This will print wine's debug msgs only to the file and then
70 auto-quit. It's probably a good idea to use this command, since wine
71 prints out so many debug msgs that they flood the terminal, eating CPU.)
73 tcsh and other csh-like shells:
75 wine -debugmsg +relay [other_options] program_name |& tee filename.out
76 tail -100 filename.out > report_file
78 bash and other sh-like shells:
80 wine -debugmsg +relay [other_options] program_name 2>&1 | tee filename.out
81 tail -100 filename.out > report_file
83 'report_file' will now contain the last hundred lines of the debugging
84 output, including the register dump and backtrace, which are the most
85 important pieces of information. Please do not delete this part, even
86 if you don't understand what it means.
88 3) Post your report to the newsgroup comp.emulators.ms-windows.wine
90 In your post, include all of the information from part 1), and insert
91 the text from the output file in part 2). If you do this, your chances
92 of receiving some sort of helpful response should be very good.
94 4) Questions and comments
96 If after reading this document there is something you couldn't figure
97 out, or think could be explained better, or that should have been
98 included, please post to comp.emulators.ms-windows.wine to let us know
99 how this document can be improved.
103 How to do regression testing using Cvs
104 -------------------------------------
106 A problem that can happen sometimes is 'it used to work before,
107 now it doesn't anymore...'. Here is a step by step procedure to
108 try to pinpoint when the problem occured. This is *NOT* for casual
111 1) get the 'full cvs' archive from winehq.
112 This archive is the cvs tree but with the tags controling the versioning
113 system. It's a big file (> 15 meg) with a name like full-cvs-<last update date>
114 (it's more than 100mb when uncompressed, you can't very well do this
115 with small, old computers or slow Internet connections)
117 2) untar it into a repository directory :
120 tar -zxffull-cvs-2000-05-20.tar.gz
123 3) extract a new destination directory
124 This directory must not be in a subdirectory of the repository else
125 cvs will think it's part of the repository and deny you an extraction
129 mv wine wine_current (-> this protects your current wine sandbox, if any)
130 export CVSROOT=/home/gerard/repository
132 cvs -d $CVSROOT checkout wine
134 Note that it's not possible to do a checkout at a given date; you
135 always do the checkout for the last date where the full-cvs-xxx snapshot
138 4) you will have now in the ~/wine directory an image of the cvs tree,
140 Now update this image to the date you want :
143 cvs -d $CVSROOT update -D "1999-06-01"
145 The date format is YYYY-MM-DD.
147 Many messages will inform you that more recent files have been
148 deleted to set back the client cvs tree to the date you asked,
151 cvs update: tsx11/ts_xf86dga2.c is no longer in the repository
153 Cvs update is not limited to upgrade to a *newer* version as
154 I have believed for far too long :-(
156 5) Now proceed as for a normal update :
161 When you have found the exact date when a bug was
162 added to Cvs, use something like :
164 cvs -d $CVSROOT diff -D "1999-07-10" -D "1999-07-12"
166 to get all the differences between the last cvs version
167 known to work and code that first displayed the misbehavior.
169 [ I did not include flags for diff since they are in my .cvsrc file :
175 From this diff file, particularly the file names, and the
176 ChangeLog, it's usually possible to find the different individual
177 patches that were done at this time.
179 If any non-programmer reads this, the fasted method to get
180 at the point where the problem occured is to use a binary
181 search, that is, if the problem occured in 1999, start at mid-year,
182 then is the problem is already here, back to 1st avril, if not,
183 to 1st october, and so on.
185 6) The next step is to start from the last working version
186 and to dig the individual contributions from
187 http://www.integrita.com/cgi-local/lwgate.pl/WINE-PATCHES/
188 (where the Wine patches mailing list is archived)
190 If the patch was done by the Wine maintainer or if it was
191 sent directly to his mail address without going first through
192 wine-patches, you are out of luck as you will never find the
193 patch in the archive.
194 If it is, it's often possible to apply the patches one by
195 one to last working Cvs, compile and test. If you have saved
196 the next candidate as /home/gerard/buggedpatch1.txt :
199 patch -p 0 </home/gerard/buggedpatch1.txt
201 Beware that the committed patch is not always identical to
202 the patch that the author sent to wine-patches, as sometimes
203 the Wine maintainer changes things a bit.
205 If you find one patch that is getting the Cvs to reproduce the problem,
206 you have almost won; post the problem on
207 comp.emulators.windows.wine
208 and there is a chance that the author will jump in to suggest a fix;
209 or there is always the possibility to look hard at the patch until it
210 is coerced to reveal where is the bug :-)
