Description
I've a problem with nginx with long URI, the few last characters of the "http filename" are replaced by first characters of the "http filename".
I've the following configuration :
server {
listen 80;
listen 443 ssl;
...
server_name srv-web.domain;
root /path/to/root/directory
rewrite ([.]*[/])$ $1/ permanent;
## cut some useless locations ##
location ~ /phpmyadmin/(.*\.php)$ {
try_files $1 $1/ $1/index.php =404;
alias /srv/www/phpMyAdmin/;
fastcgi_index index.php;
## Cut some FastCGI parameters ##
fastcgi_pass unix:/path/to/php-fpm/socket;
}
location ~ /phpmyadmin/ {
try_files $uri $uri/ $uri/index.php =404;
alias /srv/www/phpMyAdmin/;
index index.php;
}
The problem :
I can't access some files cause the http filename was rewrited strangely during process. See the error_log below :

As you can see, nginx have replaced the 4 last characters of the URI with the 4 first characters of the alias directory

I've found in the source code (in 1.1.18), the place where the string was corrupted.
In src/http/ngx_http_script.c we have this small piece of code (line 547->550) :
while (*(uintptr_t *) e.ip) { code = *(ngx_http_script_code_pt *) e.ip; code((ngx_http_script_engine_t *) &e); }
Before this piece of code :
e.request->uri.data contain : js/jquery/jquery.qtip-1.0.0.min.js (nice !!)
e.pos contain : n.js (??)
After this piece of code :
e.pos contain : themes/pmahomme/img/b_import.p/s (the previous file loaded)
e.request->uri.data contain : js/jquery/jquery.qtip-1.0.0.mi/srv/www/phpMyAdmin/themes/pmahomme/img/b_import.p/s (wouahouh !! It's a little bulk)
If you take the n-th first characters of e.request->uri.data (where n is equal to r->uri.len) you've got js/jquery/jquery.qtip-1.0.0.mi/srv exactly like in my error_log !!!
Another strange clue is that e.pos contain before the code the four overwritten letters of the string !!

I've found a (strange) workaround :
If I replace this part of my conf :
location ~ /phpmyadmin/ { try_files $uri $uri/ $uri/index.php =404; alias /srv/www/phpMyAdmin/; index index.php; }
By :
location ~ /phpmyadmin/(.*)?$ { if (!-e /srv/www/phpMyAdmin/$1) { rewrite ^ 404; } alias /srv/phpMyAdmin/$1; index index.php; }
All work nice (but it is not normal that the first conf bugs) !!

I've just tested the dev version (1.1.18) and the same bug exists.
