Prepared new release 1.3.0
1 bertho 1.15 CvsGraph 1.3.0, 20-Jul-2002
2 bertho 1.5 ===========================
3 bertho 1.1 CvsGraph creates a graphic representation of the revisions and branches in a
4     cvs/rcs repository. CvsGraph is inspired on the 'graph'-option from WinCVS. I
5     could not find something right away on the web and decided that it was time to
6     write a stand-alone version. I might have been doing some double work, but hey,
7     I like a hack.
11 bertho 1.5 New in this version
12     -------------------
13 bertho 1.14 - Implement a workaround for browsers that do not understand unordered
14     y-coordinates in the imagemap when generated upside down.
16     - Fix the slowness of CvsGraph when parsing very large (typically -kb files)
17     by bypassing the parsing of the actual deltatext. On my machine (K6-2/500/256M
18     it makes a difference of 7.5s vs 0.04s on a 93MByte file, without counting
19     disk-overhead; with disk-overhead it takes 12.5s).
20     Downside is that the logentry cannot be expanded if the file is not parsed in
21     full (see below). Use option parse_logs to enable log-expansions.
23     - Implemented logentry expansions using %l and %L. You must enable full parsing
24     (option parse_logs) for this to work.
25 bertho 1.12
26 bertho 1.15 - Fixed a possible buffer overflow in the string expansion. However, this is a
27     very low-risk overflow, since it will trash the heap and _not_ the stack.
28     Furthermore, you need to pass strings from CGI directly to cvsgraph without
29     any checks to come even close to trash the heap.
31     - Fixed a segfault on IRIX in the bsearch calls. These lookups could be called
32     with a NULL pointer and IRIX's libc doesn't like that.
34     - Implement left to right and right to left images. The entire tree can now be
35     drawn horizontally when option left_right is set. Using both left_right and
36     upside_down results in right to left images.

40     Compiling
41     ---------
42 bertho 1.9
43 bertho 1.1 create directory:
44     $ cd /where/ever/you/want
45 bertho 1.15 $ tar xzf cvsgraph-1.3.0.tar.gz
46     $ cd cvsgraph-1.3.0
47 bertho 1.3 $ ./configure
48 bertho 1.1 $ make
50     This should do the trick and you have an executable file 'cvsgraph' in the
51     current directory.
53 bertho 1.9 NOTE: The GD library is required for CvsGraph to function. Get it from
54     http://www.boutell.com, compile it and use either --with-gd-lib=DIR
55     and --with-gd-inc=DIR to specify its location. You might also have
56     to use --with-z-inc, --with-z-lib and --with-png-inc, --with-png-lib
57     for gd versions 1.6 and higher.
58     If you build with static libgd (i.e. libgd.a) and already have
59     libpng.so and/or libjpeg6b.so (i.e. dynamic), then you might want to
60     try to trick configure into adding these libs to the tests by adding
61     commandline options '--with-png-lib=.' and '--with-jpeg-lib=.'.
62 bertho 1.11 If you have linked libgd with freetype, then you might also need
63     either --with-freetype-lib or --with-freetype2-lib.
64 bertho 1.1
66 bertho 1.12
67 bertho 1.1 Installing
68     ----------
69     Put the executable file 'cvsgraph' somewhere where you think it should go.
70     Normally this would be "/usr/local/bin" or "/usr/bin". The configuration file
71     ought to be put in "/usr/local/etc" or "/etc". The exact position can be
72     overriden on the commandline anyway. Edit the configuration file to your liking
73     and you should be all set.
77     Running CvsGraph
78     ----------------
79     Do *NOT* execute the program directly from a webserver. Direct execution would
80     be very insecure. Make a wrapper cgi-script in php, perl, or whatever you
81 bertho 1.10 normally use. The easiest way is to get the ViewCVS package from their website
82     at http://viewcvs.sourceforge.net and follow the instructions.
84     Alternately, you can hack the 'cvsweb' package to call CvsGraph. There are
85     several scripts and patches available from the CvsGraph homepage (see below for
86     address). However, the scripts are no longer maintained because ViewCVS has
87     native support now.
88 bertho 1.1
89 bertho 1.2 To generate an image do something like:
90 bertho 1.5 $ cvsgraph -r /home/to/repository -m module -o mygraph.png myfile.c,v
91 bertho 1.1
92     This generates a revison/branch image of the rcs file 'myfile.c,v' and puts it
93 bertho 1.5 into 'mygraph.png'. The '-r' option is the path to the repository *located and
94 bertho 1.1 accessible* on your filesystem. The '-m' is the module in the repository. Note
95     that the extension of the file ends with ",v".
97 bertho 1.9 Just to make it clear: You cannot make images from a cvs-repository over the
98     internet as if you were using cvs. The repository files
99     must be on a locally mounted filesystem. However, you
100     can use cvsup or rsync to get a repository to your
101     local filesystem and make then image from there.
103 bertho 1.1 Type 'cvsgraph -h' to get a full list of options. If the output is not given
104     (no '-o'), then the output is written to standard output.
106 bertho 1.5 Please read the manual pages cvsgraph(1) and cvsgraph.conf(5) for more
107     information on execution and configuration.
109 bertho 1.1
111     Todo
112     ----
113     - do a better job in making a layout (auto moving branches and rubber banding
114 bertho 1.12 revision-connectors to make place). A start is made, but this is not very
115     functional yet.
116 bertho 1.1
117 bertho 1.11 - draw only a part or parts of the tree.
