Apache HTTP Server configuration inconsistencies on Solaris

Guys, there are several trivial, major and even critical inconsistencies and shortcomings concerning Solaris Apache HTTP Server configuration. I would like to use this JIRA as an umbrella covering them all. The main point I am trying to make is that there is no reason for majority of the directives to differ at all. Differences in help text and auxiliary examples are especially screaming for a unification.

run, logs and cache directories

At the moment, the Solaris Apache HTTP Server stuffs shared memory files, pid file, logs and everything in weird, semi-random locations. I don't like it at all. For instance:

• authdigest_shm in logs instead of cache directory
• mod_proxy balancer's shared mem files (slotmem-shm-peacddc71_mycluster, etc...) in logs instead of cache directory
• PID file in logs directory instead of run directory

Everything slotmem* (shm) must go into cache, logs must go into logs and pid must appear in run. In the following text, note missing PidFile and DefaultRuntimeDir directives.

Notes regarding conf/httpd.conf

• RHEL contains PidFile directive, Solaris does not.
• RHEL listens by default on Listen 127.0.0.1:80, Solaris on all interfaces.
• RHEL contains Timeout 120, KeepAlive Off, MaxKeepAliveRequests 100 and KeepAliveTimeout 15 directives with adjoining help and comments. Solaris does not.
• RHEL contains ExtendedStatus On directive with help and comments, Solaris does not.
• RHEL ServerAdmin is ServerAdmin Administrator@localhost, Solaris is root@localhost.
• RHEL contains default ServerName, ServerName localhost:80, Solaris has it commented out: #ServerName www.example.com:80. It causes warnings on vanilla startup after postinstall.
• RHEL contains and Solaris does not: UseCanonicalName Off with adjoining help and comments.
• Solaris contains and RHEL does not:

  <Directory "/opt/del/jws-3.0/var/www">
          AllowOverride None
          # Allow open access:
          Require all granted
      </Directory>
  

• Solaris contains:

  <IfModule dir_module>
          DirectoryIndex index.html
      </IfModule>
  

  while RHEL has: DirectoryIndex index.html index.html.var

• RHEL contains AccessFileName .htaccess and Solaris does not.
• RHEL

  <Files ~ "^\.ht">
      Require all denied
  </Files>

  and Solaris

  <Files ".ht*">
      Require all denied
  </Files>

• RHEL has HostnameLookups Off, Solaris does not.
• RHEL

  <IfModule reqtimeout_module>
    RequestReadTimeout header=20-40,MinRate=500 body=20,MinRate=500
  </IfModule>

  Solaris does not have anything like it.

• Solaris: EnableSendfile on, RHEL: #EnableSendfile off
• RHEL Logging:

  LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
  LogFormat "%h %l %u %t \"%r\" %>s %b" common
  LogFormat "%{Referer}i -> %U" referer
  LogFormat "%{User-agent}i" agent

  Solaris Logging:

  LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
  LogFormat "%h %l %u %t \"%r\" %>s %b" common

• RHEL ServerSignature On, Solaris does not have the directive set.
• RHEL

  Alias /icons/ "/home/mbabacek/JWS/rhel64/jws-3.0/httpd/www/icons/"
  <Directory "/home/mbabacek/JWS/rhel64/jws-3.0/httpd/www/icons">
      Options Indexes MultiViews
      AllowOverride None
      Require all granted
  </Directory>

  Solaris nothing regarding icons, no AddIconByEncoding, no AddIcon, no DefaultIcon.

• RHEL

  <IfModule mod_dav_fs.c>
      # Location of the WebDAV lock database.
      DAVLockDB /var/lib/dav24/lockdb
  </IfModule>

  . Solaris nothing, no WebDav section.

• RHEL IndexOptions FancyIndexing VersionSort NameWidth=* HTMLTable, Solaris does not have any such directive.
• RHEL has ReadmeName README.html, HeaderName HEADER.html and IndexIgnore .??* ~ *# HEADER README* RCS CVS *,v *,t, Solaris nothing like that.
• RHEL Language settings and internationalization, Solaris none.
• RHEL internationalizes error responses, Solaris nothing.
• RHEL BrowserMatch directive, Solaris nothing.
• RHEL offers examples on SetHandler server-status and SetHandler server-info, Solaris nothing like that.
• RHEL describes proxy and caching examples for mod_proxy and mod_disk_cache, Solaris does not offer anything like that in any of its config files.
• RHEL presents VirtualHosts examples, Solaris does nothing like that.

  conf.modules.d/00-base.conf

  RHEL contains DefaultRuntimeDir /home/mbabacek/JWS/rhel64/jws-3.0/httpd/run Solaris does not.

  conf.modules.d/00-mpm.conf

  RHEL contains default MPM directives, Solaris does not.

  <IfModule prefork.c>
  StartServers       8
  MinSpareServers    5
  MaxSpareServers   20
  ServerLimit      256
  MaxRequestWorkers       256
  MaxConnectionsPerChild  4000
  </IfModule>
  <IfModule worker.c>
  StartServers         2
  MaxRequestWorkers         150
  MinSpareThreads     25
  MaxSpareThreads     75
  ThreadsPerChild     25
  MaxConnectionsPerChild  0
  </IfModule>

  conf.modules.d/00-proxy.conf

  RHEL loads LoadModule proxy_fdpass_module modules/mod_proxy_fdpass.so. Solaris does not. See JWS-135.

  conf.modules.d/01-cgi.conf

  Solaris contains a superfluous directive:

  <IfModule mpm_winnt_module>
     LoadModule cgi_module modules/mod_cgi.so
  </IfModule>

  UserDir

  Solaris contains conf.modules.d/userdir.conf whereas RHEL contains conf.d/userdir.conf. Content is the same though.

  conf.d/ssl.conf

• RHEL contains Listen localhost:443, Solaris Listen 443 https
• Different help comment and auxiliary examples.
• RHEL has AddType application/x-x509-ca-cert .crt,AddType application/x-pkcs7-crl .crl. Solaris does no such thing.
• RHEL sets SSLPassPhraseDialog exec:/home/mbabacek/JWS/rhel64/jws-3.0/httpd/sbin/httpd-ssl-pass-dialog, whereas Solaris SSLPassPhraseDialog builtin.
• Note that postinstall didn't change the privileged directory on Soalris: RHEL SSLSessionCache shmcb:/home/mbabacek/JWS/rhel64/jws-3.0/httpd/run/sslcache(512000), Solaris SSLSessionCache shmcb:/run/httpd/sslcache(512000).
• RHEL contains:

  #   Semaphore:
  #   Configure the path to the mutual exclusion semaphore the
  #   SSL engine uses internally for inter-process synchronization. 
  Mutex default

  . Solaris has nothing like that.

  conf.d/welcome.conf

  RHEL

  <LocationMatch "^/+$">
      Options -Indexes
      ErrorDocument 403 /.noindex.html
  </LocationMatch>
  <Directory /home/mbabacek/JWS/rhel64/jws-3.0/httpd/www/error>
      AllowOverride None
      Require all granted
  </Directory>
  Alias /.noindex.html /home/mbabacek/JWS/rhel64/jws-3.0/httpd/www/error/noindex.html

  and Solaris just

  <LocationMatch "^/+$">
      Options -Indexes
      ErrorDocument 403 /error/noindex.html
  </LocationMatch>

Note that both installations had their postinstall scripts executed. The RHEL one in /home/mbabacek/JWS/rhel64/jws-3.0/httpd and the Solaris one in /opt/del/jws-3.0/etc.

WDYT?
