[Bug 58813] New: Incoming requests hang after a website using the
ISAPI connector is restarted
https://bz.apache.org/bugzilla/show_bug.cgi?id=58813
Bug ID: 58813
Summary: Incoming requests hang after a website using the ISAPI
connector is restarted
Product: Tomcat Connectors
Version: 1.2.33
Hardware: PC
Status: NEW
Severity: regression
Priority: P2
Component: isapi
Assignee: dev@tomcat.apache.org
Reporter: matthewreiter@hotmail.com
OS: Windows Server 2012 R2 Standard
If isapi_redirect.dll is configured at the website level (rather than
globally), when the website is restarted using IIS Manager, the ISAPI
redirector is restarted, too. At this point any further HTTP requests will hang
until IIS is restarted.
I've traced the problem back to this commit:
commit 2f209a0d25e379b7cb29a9aad74dd71a95471ae5
Author: Mladen Turk <mt...@apache.org>
Date: Tue Mar 6 12:21:02 2012 +0000
Use global mutex instead critical section so that multiple instance don't
in
it at once in case IIS starts multiple processes

In TerminateFilter (in jk_isapi_plugin.c), ReleaseMutex is being called with
the address of the init_cs variable rather than its value, causing init_cs to
never be released. As a result, when GetExtensionVersion is subsequently
called, it is unable to acquire init_cs and so the plugin never finishes
initializing. I was able to confirm that removing the extra "&" fixes the
problem.

Thanks a lot for the quick conformation!
I meanwhile found my old Visual C++ 6.0 CD and will build a "custom" version as
well, because I can't put the official version into production with this bug!
@Source owner of jk_isapi_plugin.c:
Please, please, please fix this "typo" in the next official version!
Pretty please, with sugar on top?!

Hi!
I added your patch description to the following silimar bug:
https://bz.apache.org/bugzilla/show_bug.cgi?id=59334
It seems to be the same bug.
Here (again) the details of what should be done:
TerminateFilter (in jk_isapi_plugin.c)
version 1.2.41
Line 2424: ReleaseMutex(&init_cs);
should be: ReleaseMutex(init_cs);
That's the patch you have tested successfully, right?
kind regards
swobi

Good question. It has been over a year since the last release. I'll start a
discussion on the dev list.
