Rowe, Jr. -Date: June 7th '00 -Subject: service monitoring in Apache 1.3.13 - -The concept for a taskbar monitor has been thrown around -for a very long while. 1.3.13 introduced Win9x services, -and that added fuel to the mix. Here are some sideband -observations I've made for other developers... - -About Apache as a console, don't start Apache hidden without -any command line arguments if you want to launch it yourself -in a hidden window (it will do the classic test for -AllocConsole/FreeConsole)... drop in some arguments such as -the -f or -r option and it will fly without thinking it is a -service under 9x and NT. - -Rule two, don't use --ntservice as an argument, ever. Only -the Windows NT Service Control Manager is allowed to pass that -flag, and only that flag, when it runs Apache.exe. Do use ---ntservice as the sole argument to the executable name if -you are installing an Apache NT service yourself. - -Rule three, use -k start and -n name when maintaining the -HKLM/Software/Microsoft/Windows/CurrentVersion/RunServices -list, since there is no other way for Apache to know what -the service is named :) And look at any 9x installed service's -RunServices entry in the registry for the start service semantic. - -Rule four, use the WinNT Service Control Manager exclusively -for starting, stopping and restarting Apache as an NT service. -The restart signal is the value 128, as documented in service.h -and service.c - this will continue to work in Apache 2.0. If -it fails, you are handling an older version (pre 1.3.13) of -Apache, and need to stop and then start the service instead. - -Rule five, use the legacy pid-named events to signal Win9x -service Apache to restart and stop the service. But don't -bother looking for httpd.pid files... you can get the pid -right from the hidden service control window. Apache 1.3.13 -and 2.x create a hidden window named for the name of the -service (without the spaces), with a window class of -"ApacheWin95ServiceMonitor", so can use FindWindow to track -down running Win9x services. See the service.c code for how -I accomplished this pretty simply in the -k stop/-k restart -handler. - -Taskbar Monitor App -------------------- - -Basic requirements: a C code application using strictly the -Win32 API, and not MFC or other Win32 frameworks. Could use -the service.c module to share some basic functions. That -module could be extended in Apache 2.0 to make this all easier. - -I think we are looking for an external app that simply acts -as a monitor or allows a stopped service to be started. If -the user logs off, we loose the monitor app, but installed as -a shortcut in the Start group or in the registry key -HKLM/Software/Microsoft/Windows/CurrentVersion/Run -we will be just fine. I'd like to see the monitor run only -one instance to monitor all running services, for memory -and resource conservation. - -I was thinking that the hover/iconbar title would tell them -"Test service is running", or "Test service is stopped". -If they left click, they could stop or restart, or simply -start if it is stopped. There could be a preference that -each service doesn't get it's own individual task icon unless -it is running, if it is a manual start service (or missing -from the RunServices list, which is the equivilant under 9x). - -If a specific service is set to Auto start or is in the -RunServices Win9x registry key, we must show them the stopped -icon, of course. We might also keep the icon for any running -service that stops abruptly. But there could be a 'single -icon' option for the taskbar icon monitor that says show only -a single status icon, for simplicity if the administrator runs -many Apache services. - -But I was hoping that any right click would provide a menu -of all Apache services with their status. e.g. - Test service is stopped - Apache_2 service is running - MyWeb service is running -and each would do the logical submenu, same as if that -specific taskbar icon were left clicked, offering to start or -offering to stop or restart the server, as appropriate. - -Finally, to identify all installed Apache services, just query -the registry key HKLM\SYSTEM\CurrentControlSet\Services for any -key that has the ImagePath value of "...\Apache.exe"... (quotes -are significant here, if the leading quote is ommitted the -entire string ends with the text \Apache.exe - based on Apache's -own service installer in every released version.) diff --git a/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/Makefile.in b/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/Makefile.in deleted file mode 100644 index 38e598ed..00000000 --- a/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/Makefile.in +++ /dev/null @@ -1,5 +0,0 @@ - -LTLIBRARY_NAME = libmpmt_os2.la -LTLIBRARY_SOURCES = mpmt_os2.c mpmt_os2_child.c - -include $(top_srcdir)/build/ltlib.mk diff --git a/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/config5.m4 b/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/config5.m4 deleted file mode 100644 index b27c296d..00000000 --- a/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/config5.m4 +++ /dev/null @@ -1,5 +0,0 @@ -if test "$MPM_NAME" = "mpmt_os2" ; then - AC_CACHE_SAVE - APACHE_FAST_OUTPUT(server/mpm/$MPM_NAME/Makefile) - APR_ADDTO(CFLAGS,-Zmt) -fi diff --git a/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/mpm.h b/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/mpm.h deleted file mode 100644 index 15f341dd..00000000 --- a/rubbos/app/httpd-2.0.64/server/mpm/mpmt_os2/mpm.h +++ /dev/null @@ -1,34 +0,0 @@ -/* Licensed to the Apache Software Foundation (ASF) under one or more - * contributor license agreements.
