[squid-users] Squid BUG: assurance failed: tok.skip(WellKnownUrlPathPrefix())

[Loučanský Lukáš]

Ok - thanks for your reply. But this does not clarify it fully. You said cachemgr.cgi auto-detects the existence of MGR_INDEX template. But what is it supposed to do if none is found? Just displaying the message about missing MGR_INDEX? Or doing the old style "Cache Manager menu"? I have applied Alex's  patch to re-enable cache_object URI and now it obviously works - both cache_object and squid-internal-mgr. I mean - squidclient from debian packages (v4.6) works and the one compiled with squid v6.3 works too. Because of my old network NOC system a use a very old cachemgr (in fact version index.cgi/3.1.16) to ask the current v6.3 squid for its data and now it works too. 
But as I said previously - the current cachemgr.cgi displays "Internal Error: Missing Template MGR_INDEX" without MGR_INDEX file and the content of the MGR_INDEX file while it is present. As I found out - it does not like files with content with some tags or javascript references etc. Have not ruled it out - but the MGR_INDEX file provided in the https://github.com/yadij/cachemgr.js/  project just makes the mentioned assert fail in the membuf.cc.

Note - I do not like the fact it's looking for the MGR_INDEX file upon start or reconfigure - as it makes the changes more stressful while I have to call reconfigure on the working squid.

FYI, the cachemgr.cgi provided by current Squid tries to auto-detect the 
existence of a working MGR_INDEX and simply provides a URL to that 
instead of doing the "old" CGI interface things.

The reasons to use it are:
  1) when managing very outdated Squid versions, or
  2) managing Squid which have not yet had a tool providing MGR_INDEX 
installed yet.


The recent changes to squidclient "mgr:" support and the cache_object:// 
  URL scheme have had a few issues. I am currently setting up a test 
environment to analyze and re-document the new/current situation. 
Hopefully some detailed info can be added to the wiki in the coming days.
