[Bug 65402] EventSources get stuck with H2 but working in http/1.1

--- Comment #43 from Stefan Eissing  ---
If you don't know what is going on, write a helper. Today I wrote
 to look at your logs.

My analysis now is that your webapp runs into the h2 DoS protection. mod_http2
does not really like it when the client starts and then kills requests. But it
likes when the client reads requests completely and without stalling.

There is a "mood" counter and when mood drops, the number of active requests
that a client may perform is reduced. When mod_http2 is happy, this limit is
increased.

The stream with the late starts happen at a time, when the limit has been
exhausted. E.g. in the latest log, the limit was reduced to 16 and 16 request
were ongoing when a new one came in. This means there will be no worker
assigned to that request until another of the 16 returns.

Since there are requests hanging, waiting on the next SSE chunk to then abort,
this may take some time. In the last log the 16 seconds.

So, I understand what is happening. That is something.

I do not have a good idea how to improve this. Have to think a bit on that.

Patch for both bug 65419 and bug 65429.

it ASAP.

I've just tested your patch and it works. Thanks.

Is there a repository where all those patches are collected?

Don't confuse/merge matchable and non-matchable proxy workers at loading

Could you please try this patch?

The issue is a change in 2.4.48 (r1880772) to allow for parameters
(enablereuse, ttl..) in /ProxyPassMatch workers with '$n'
substitution in the URL, like /ProxyPass workers.

This patch should fix the regression that makes matchable and non-matchable
workers be confused/merged at loading, which is why when the worker
http://localhost:8081 (non-matchable) is defined first it blinds the second
worker http://localhost:8081/wmts/$1/webmercator/$2 (matchable), thus no worker
exists to handle "/tiles/osm/19/272348/174392.png" which ends up being not
found in the DocumentRoot.

Note that there is another issue reported in bug 65419 about this change,
another patch is available there for a full fix (the two patches can be applied
with no conflict).

[Bug 65429] New: order of ProxyPass and ProxyPassMatch seems to matter

2021-07-03 Thread bugzilla 
https://bz.apache.org/bugzilla/show_bug.cgi?id=65429

Bug ID: 65429
   Summary: order of ProxyPass and ProxyPassMatch seems to matter
   Product: Apache httpd-2
   Version: 2.4.48
  Hardware: PC
OS: Linux
Status: NEW
  Severity: normal
  Priority: P2
 Component: mod_proxy
  Assignee: bugs@httpd.apache.org
  Reporter: tob...@gmx.de
  Target Milestone: ---

# summary
After upgrading from apache2 v2.4.46 to v2.4.48, the order of ProxyPass and
ProxyPatchMatch seems to matter.

# test requests
1. GET http://demo.tobwen.local/internal/
2. GET http://demo.tobwen.local/tiles/osm/19/272348/174392.png

# config (1)

ServerName demo.tobwen.local
DocumentRoot /var/www/html/

ProxyPass "/internal" "http://localhost:8081;
ProxyPassMatch "^/tiles/([^/\.]+)/(\d+/\d+/\d+.png)$"  
"http://localhost:8081/wmts/$1/webmercator/$2;


# results (1)
On v2.4.46 (and earlier), both test requests worked as expected.
On v2.4.48, the second request suddenly throws an ERROR 404.

# observation
Let's change the order of ProxyPass and ProxyPassMatch.

# config (2)

ServerName demo.tobwen.local
DocumentRoot /var/www/html/

ProxyPassMatch "^/tiles/([^/\.]+)/(\d+/\d+/\d+.png)$"  
"http://localhost:8081/wmts/$1/webmercator/$2;
ProxyPass "/internal" "http://localhost:8081;


# results (2)
Crazy, now the requests work without a problem.

# conclusion
This seems to be a regression since it worked in earlier versions.
