Hello!<br /><br />We want to use mod_glusterfs, but it has bugs. We use
glusterfs on our production servers (version glusterfs-1.4.0pre5 ). Our web
server is lighttpd 1.5 rev. 1992. <br /><br />We decided to test
mod_glusterfs, but we discovered that it killed lighty (SEGFAULT). With valgrind
I discovered that the problem is near line 1453 of mod_glusterfs.c. I looked it
and I decided to change the code:<br /><br />FROM:<br
/>URIHANDLER_FUNC(mod_glusterfs_response_done) {<br /> plugin_data
*p = p_d;<br /> UNUSED (srv);<br /> mod_glusterfs_ctx_t
*ctx = con->plugin_ctx[p->id];<br /><br />
con->plugin_ctx[p->id] = NULL;<br /> if (ctx) {<br />
if (ctx->glusterfs_path) {<br /> free
(ctx->glusterfs_path);<br /> }<br /> }<br /><br
/> free (ctx);<br /> return HANDLER_GO_ON;<br />}<br
/><br />TO:<br />URIHANDLER_FUNC(mod_glusterfs_response_done) {<br />
plugin_data *p = p_d;<br /> UNUSED (srv);<br />
mod_glusterfs_ctx_t *ctx = con->plugin_ctx[p->id];<br /><br />
if (ctx) {<br /> if (ctx->buf) {<br />
free (ctx->buf);<br /> ctx->buf = NULL;<br />
}<br /> if (ctx->glusterfs_path) {<br />//
free (ctx->glusterfs_path);<br /> buffer_free
(ctx->glusterfs_path);<br /> ctx->glusterfs_path =
NULL;<br /> }<br /> }<br />
con->plugin_ctx[p->id] = NULL;<br /> free (ctx);<br /><br
/> return HANDLER_GO_ON;<br />}<br /><br />Now It works, but when I
stop downloading proces lighty kills itself (server.c.847: (trace) [note]
graceful shutdown started by UID=0, PID=0). Now I don`t know what to do.<br
/><br />I updated glusterfs to the latest version, but when I started lighty, it
showed:<br /><br />## lighttpd error glusterfs version 2.0.1 and above<br
/>Starting web server: lighttpd2009-07-08 12:54:55: (plugin.c.266) dlopen()

/>2009-07-08 12:54:55: (server.c.1185) loading plugins finally failed<br /><br
/>It looks like this method doesn`t exist any more.<br /><br />I will be very
thankful if you fix these bugs and people can use mod_glusterfs freely. I hope
that you send me some information about the problems I described above.<br /><br
