CvsGraph 1.5.1, 23-Oct-2004
|
| 2 |
===========================
|
| 3 |
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.

New in this version
|
| 12 |
-------------------
|
| 13 |
|
| 14 |
- Add patch from Henrik Carlqvist <henca@users.SourceForge.net>
|
| 15 |
* add option rev_hidenumber for disabling revision number display.
|
| 16 |
* add option tag_ignore_merge for disabling merge_from/merge_to display
|
| 17 |
if matched with tag_ignore.
|
| 18 |
* add resorting of branches on how many revisions they have. This saves
|
| 19 |
space under circumstances.
|
| 20 |
|
| 21 |
- Add option merge_findall so that merge_from/merge_to tags can have multiple
|
| 22 |
matches.
|
| 23 |
|
| 24 |
- Add the patches supplied by Ville Skytta <ville.skytta@iki.fi>
|
| 25 |
* fix spelling in the manpages and config file
|
| 26 |
* fix & -> & problem in config
|
| 27 |
* fix generics in wrapper example
|
| 28 |
|
| 29 |
- Add a fix for the zimezone problem as suggested by Henrik Carlqvist
|
| 30 |
<henca@users.SourceForge.net> by using the environment.
|
| 31 |
|
| 32 |
- Fix a bug in the detection of branch-numbers in the logical ,v file structure
|
| 33 |
(reported by Daniel Dumitrache <ddumitrache@bitdefender.com>). The branch was
|
| 34 |
deduced from the revision, but that would fail for revision numbers that are
|
| 35 |
like magic branch-numbers (x.x.0.x) because they were interpreted. These
|
| 36 |
revision numbers are now correctly handled.
|
| 37 |
|
| 38 |
- Added patch from Gordon Hollingworth <Gordon.Hollingworth@TTP.com> to use
|
| 39 |
mergepoints as implemented by CVSNT. Adapted the patch to enable both
|
| 40 |
tag-detected merges and mergepoints to be shows at the same time.
|
| 41 |
|
| 42 |
- Implement selection of png compression level with image_compress and enable
|
| 43 |
interlacing (progressive load) for both png and jpeg images with
|
| 44 |
image_interlace.

Compiling
|
| 49 |
---------
|
| 50 |
|
| 51 |
create directory:
|
| 52 |
$ cd /where/ever/you/want
|
| 53 |
$ tar xzf cvsgraph-1.5.1.tar.gz
|
| 54 |
$ cd cvsgraph-1.5.1
|
| 55 |
$ ./configure
|
| 56 |
$ make
|
| 57 |
|
| 58 |
This should do the trick and you have an executable file 'cvsgraph' in the
|
| 59 |
current directory.
|
| 60 |
|
| 61 |
NOTE: The GD library is required for CvsGraph to function. Get it from
|
| 62 |
http://www.boutell.com, compile it and use either --with-gd-lib=DIR
|
| 63 |
and --with-gd-inc=DIR to specify its location. You might also have
|
| 64 |
to use --with-z-inc, --with-z-lib and --with-png-inc, --with-png-lib
|
| 65 |
for gd versions 1.6 and higher.
|
| 66 |
If you build with static libgd (i.e. libgd.a) and already have
|
| 67 |
libpng.so and/or libjpeg6b.so (i.e. dynamic), then you might want to
|
| 68 |
try to trick configure into adding these libs to the tests by adding
|
| 69 |
commandline options '--with-png-lib=.' and '--with-jpeg-lib=.'.
|
| 70 |
If you have linked libgd with freetype, then you might also need
|
| 71 |
either --with-freetype-lib or --with-freetype2-lib.
|
| 72 |
|
| 73 |
There are often precompiled binaries for Linux, FreeBSD, NetBSD and Windows
|
| 74 |
(and probably other OSes too). Check your local mirror for details. I also have
|
| 75 |
some links on the homepage for precompiled binaries. Please do not complain to
|
| 76 |
me about these binaries.
|
| 77 |
|
| 78 |
|
| 79 |
|
| 80 |
Installing
|
| 81 |
----------
|
| 82 |
Put the executable file 'cvsgraph' somewhere where you think it should go.
|
| 83 |
Normally this would be "/usr/local/bin" or "/usr/bin". The configuration file
|
| 84 |
ought to be put in "/usr/local/etc" or "/etc". The exact position can be
|
| 85 |
overriden on the commandline anyway. Edit the configuration file to your liking
|
| 86 |
and you should be all set.
|
| 87 |
|

Running CvsGraph
|
| 91 |
----------------
|
| 92 |
Do *NOT* execute the program directly from a webserver. Direct execution would
|
| 93 |
be very insecure. Make a wrapper cgi-script in php, perl, or whatever you
|
| 94 |
normally use. There are several web-based viewers with CvsGraph support:
|
| 95 |
|
| 96 |
- ViewCVS http://viewcvs.sourceforge.net
|
| 97 |
- CVSweb http://www.freebsd.org/projects/cvsweb.html
|
| 98 |
- Chora http://www.horde.org/chora/
|
| 99 |
|
| 100 |
|
| 101 |
To generate an image do something like:
|
| 102 |
$ cvsgraph -r /home/to/repository -m module -o mygraph.png myfile.c,v
|
| 103 |
|
| 104 |
This generates a revison/branch image of the rcs file 'myfile.c,v' and puts it
|
| 105 |
into 'mygraph.png'. The '-r' option is the path to the repository *located and
|
| 106 |
accessible* on your filesystem. The '-m' is the module in the repository. Note
|
| 107 |
that the extension of the file ends with ",v".
|
| 108 |
|
| 109 |
Just to make it clear: You cannot make images from a cvs-repository over the
|
| 110 |
internet as if you were using cvs. The repository files
|
| 111 |
must be on a locally mounted filesystem. However, you
|
| 112 |
can use cvsup or rsync to get a repository to your
|
| 113 |
local filesystem and make then images from there.
|
| 114 |
|
| 115 |
Type 'cvsgraph -h' to get a full list of options. If the output is not given
|
| 116 |
(no '-o'), then the output is written to standard output.
|
| 117 |
|
| 118 |
Please read the manual pages cvsgraph(1) and cvsgraph.conf(5) for more
|
| 119 |
information on execution and configuration.

Contributed code
|
| 124 |
----------------
|
| 125 |
- contrib/automatic_documentation:
|
| 126 |
If you are interested in tag-management with respect to the correct branch
|
| 127 |
information, then I suggest that you take a look at the contribution from
|
| 128 |
Henrik Carlqvist. He submitted some server-side scripts that can manage tags
|
| 129 |
in a better fashion than cvs on its own.

Todo
|
| 134 |
----
|
| 135 |
- do a better job in making a layout (auto moving branches and rubber banding
|
| 136 |
revision-connectors to make place). A start is made, but this is not very
|
| 137 |
functional yet.
