gitblit
gitblit copied to clipboard
graph images are hard coded and do not view with mod_proxy
Originally reported on Google Code with ID 559
What steps will reproduce the problem?
1.Install war on Glassfish
2.mod_proxy reverse proxy
3.context_path -> gitblit
4. when viewing repository:summary the graph does not appear.
What is the expected output? What do you see instead?
I expect to see the commit graph
I see a broken image link
What version of the product are you using? On what operating system?
v1.6.2
Suse server : multiple browsers on multiple os
Please provide any additional information below.
Inspecting the image shows that the servlet has hard coded the url to the glassfish
server and does not use a relative path. Hence the reverse proxy can do nothing about
it beacause the web page is served up with a link which it can not access.

Sorry, should add, the url is hard coded with the glassfish host and ip address

Can't you use mod_rewrite here too?

When the page is written, the host is hard coded in the img url . mod_rewrite does
not see the content of the page being delivered, just the place where the file is going
to /coming from.
My suspicion is that BranchGraphServlet.java is hard coding the img url:
<code>
public static String asLink(String baseURL, String repository, String objectId, int
numberCommits) {
if (baseURL.length() > 0 && baseURL.charAt(baseURL.length() - 1) == '/') {
baseURL = baseURL.substring(0, baseURL.length() - 1);
}
return baseURL + Constants.BRANCH_GRAPH_PATH + "?r=" + repository
+ (objectId == null ? "" : ("&h=" + objectId))
+ (numberCommits > 0 ? ("&l=" + numberCommits) : "");
}
</code>

Your suspicions are confirmed, it does hard-code an url.

work around:
a2enmod mod_substitute
add the location tag which does the proxying
<location /gitblit>
ProxyPass http://127.0.0.1:8080/gitblit
ProxyPassReverse http://127.0.0.1:8080/gitblit
AddOutputFilterByType SUBSTITUTE text/html
Substitute "s|http://127.0.0.1:8080/|http://<YOUR SERVER HOST>/|i"
</location>
NB change <Your SERVER HOST> to the host name of the world facing server
AND restart apache
