Requesting https://commons.wikimedia.org/wiki/User:CommonsDelinker/commands?action=edit often returns HTTP 504: Gateway Timeout. This does not happen when requesting the page with a high frequence but if you do it e.g. once an hour. Just look at https://commons.wikimedia.org/w/index.php?title=User:Rillke/CDC_mystery&action=history where I dump the profiling report of this page using https://commons.wikimedia.org/wiki/User:Rillke/profile.js -- about every third request fails. Other users experience this issue as well: https://commons.wikimedia.org/w/index.php?title=Commons:Administrators%27_noticeboard&oldid=104206956#Extremely_slow_performance_to_open_edit_interface_of_COM:CDC If I remember correctly, this is an issue for a long time. Updating the page via API often works without any issues (but is slow). The page is regularly queried and updated by a bot: http://toolserver.org/~delinker/helper.txt
Isn't this just the "standard" timeout for (uncached/just edited) pages with a lot of templates, like [[m:User:Cbrown1023/Logos]]?
(In reply to comment #1) The issue is that there were not a lot of templates on the page at the time the requests failed: Exmaple: 17:40, 14 September 2013 ( https://commons.wikimedia.org/w/index.php?title=User:Rillke/CDC_mystery&oldid=104315333 ) https://commons.wikimedia.org/w/index.php?title=User:CommonsDelinker/commands&oldid=104314668 ( https://commons.wikimedia.org/w/index.php?title=User:CommonsDelinker/commands&action=edit&oldid=104314668 ) CPU time usage 0.656 seconds Real time usage 0.767 seconds Preprocessor visited node count 1285/1000000 Preprocessor generated node count 4672/1500000 Post-expand include size 60326/2048000 bytes Template argument size 29773/2048000 bytes Highest expansion depth 12/40 Expensive parser function count 33/500
So here is the complete message: <head><title>504 Gateway Time-out</title></head> <body bgcolor="white"> <center><h1>504 Gateway Time-out</h1></center> <hr><center>nginx/1.1.19</center> </body> </html> ---- https://commons.wikimedia.org/w/index.php?title=User:Rillke/CDC_mystery&oldid=104491400 22:37, 16 September 2013 ---- If you need a special response header for debugging, please let me know.
And I found something interesting: * https://commons.wikimedia.org/w/index.php?title=User:Rillke/CDC_mystery&oldid=104442630 * https://commons.wikimedia.org/w/index.php?title=User:Rillke/CDC_mystery&oldid=104401867 The following took ~50s! query: SELECT log_id,log_type,log_action,log_timestamp,log_user,log_user_text,log_namespace,log_title,log_comment,log_params,log_deleted,user_id,user_name,user_editcount,ts_tags FROM `logging` FORCE INDEX (page_time,user_time,log_user_type_time) LEFT JOIN `user`

Can a tech please confirm this is an instance of Bug 53577 ?
Sean: Could you answer comment 6, please? Thanks in advance!
The truncated query in comment #6 comes from the same class as bug 53577 but forces different indexes. So, possibly it's the same type of problem, but need to see a complete example.
(In reply to comment #8) Is there anything I could help with?
This error is not in the tool's code though, adding keyword
There is nothing the maintainers of the tool can do here, so it shouldn't be a bug of the tool, IMHO.
I see. Thanks for correcting me!
Is that still an issue experienced?
(In reply to Andre Klapper from comment #14) > Is that still an issue experienced? Sorry for the late reply.. Nope. Worked fine in the last months. (Maybe a other software change fixed this, closing now as RES - FIX)
