When trying to compile in modperl with the 10x patches I get the following 
error.:
----------------------------------------------
Connection.xs: In function `XS_Apache__Connection_remote_ip':
Connection.xs:102: incompatible types in assignment

make[1]: Leaving directory `/ext/install/apache_1.3.9'

-------------------------------------------
The 1.3.9 src was patched was the allin 10x patch and
compiling goes fine without modperl
How can I solve this?
TIA

Yup, looks like an incompatibility I introduced.  The first of several
I'm sure.

The offending bit of code in my mod_perl tree looks like this:
    if(items > 1)
         conn->remote_ip = pstrdup(conn->pool, (char *)SvPV(ST(1),na));

I changed the remote_ip member of struct conn_rec from a char* to a
char[] so assigning to it is no longer valid.  You can change it back or
you can change mod_perl's Connection.xs to copy to the string rather
than assign to it.  You will also need to update the new member
remote_ip_len.  The new bit of code looks like this and compiles for me:

    if(items > 1) {
         strcpy(conn->remote_ip, (char *)SvPV(ST(1),na));
         conn->remote_ip_len = strlen(conn->remote_ip);
    }

I found that it is easy to apply both mod_ssl and the SGI patches as
long as the SGI patches are applied first.  There are still conflicts
but they are straightforward to resolve.  I, and maybe others on the
Accelerating Apache mailing list, can help you with specific problems
you may encounter.

Hello,

I'm having trouble compiling the patched apache 1.3.9, and I was wondering
if you could supply a binary distro of it.  I downloaded and installed the
Bindist from apache's ftp server and its remarkably slower than netscape, so
i found these patches and tried to compile.  no luck.  I've compiled apache
successfully on linux many times, and I don't want to debug it for IRIX :)

Thank you,

Russ Mann

I'm sorry you're having trouble with my patches.  If you have specific
questions I will try to help.  Unfortunately the Apache license
prohibits me from distributing binary versions.

Hi,

Can anybody help me out with this? its probably a pretty dumb =
question...

I'm new to SGI machines, I've downloaded the apache 1.3.9 binary from =
the oss distribution site, and installed it using the software manager.=20

It seems to be configured correctly - I have setup about 20 virtual =
hosts.

The machine (an Indy) is standalone, so all the VHosts have entries in =
the HOSTS file with the IP address of the host.

Whenever I try to connect to a VHost I get the standard SGI webpage that =
says "<machine name> <user accounts>"

Is there a webserver already running that I need to disable?

I've commented out httpd in the inetd.conf, and also removed webface =
from the rc0.d

am I missing something here?

Thanks

This sounds like the Outbox web server.  Try running "chkconfig outbox
off" as root and either rebooting or killing the relevant processes.  If
that doesn't work, we'll try something else.

Mike:

I've been experimenting with your Apache 10xpatch-1.3.1
patchset and noticed that when running your patched
version, the Last-Modified: timestamp on static files
(e.g. .gif) seems to be the same as the request time,
e.g. if I keep pulling the file, the Last-Modified:
time seems to change along with that.
 
I tried with QSC disabled and stat cache disabled/enabled
(originally didn't even apply the 10xpatch-1.3.1-1 incremental
patch), any combination doesn't change the observed result,
Last-Modified: doesn't reflect the actual file's mtime.
This is a problem as it tends to defeat any caching :(

Also I tried not defining "SPEED_DAEMON" and not enabling
FAST_TIME or any of the log-related defines (really just
enabling QSC, NO_GRACEFUL, and STAT_CACHE). Still seeing
the behaviour described above.

Any ideas about this? Thanks in advance ...

RW

I found that by mmap'ing files, then the Last Modified:
timestamp for the files in mmap are correct (but wrong
for anything not explicitly mapped via mmapfile directive).

Sorry for the delayed response.  I've been having way too much fun
working on Apache/2.0a1.

You are correct, this is a bug I introduced.  I will post the fix as
10xpatch-1.3.12-2 right away.  Thank you.

You also wrote (under separate cover):

If httpd -L says "Ignored because !USE_QSC" that means USE_QSC is not
defined and the QSC is not compiled into your server.  Are you sure
you're defining it (or SPEED_DAEMON) the right way?  I use:
	$ CFLAGS="-DSPEED_DAEMON" configure
for sh and
	% env CFLAGS="-DSPEED_DAEMON" configure
for csh (among other flags and options).

Also, you need to pass ?qsc to the server-status page only when you are
setting a value, as in ?qsc=full or ?qsc=quick.  The status page always
includes some QSC info (as long as USE_QSC is defined).

I applied your incremental patch -2 and all is well.
About the QSC problem I was having, it was my fault
(was specifying OPTIM= string wrong in the RPM .spec,
when I fixed the configure line it works as you said).

I have some other compile questions about your patch.
I'm trying to use "SINGLE_LISTEN_UNSERIALIZED_ACCEPT"
as I'm running a dual-processor (2xPIII-500 Xeon) box
and want to avoid the performance hit that serialization
incurs. Also I read somewhere that not using the above
define hurts latency to some degree (latency is important
to my application)?.

The problem comes in when I try to compile with this
define, the build fails complaining about dynamic linker
functions not defined or something. When I add "-ldl"
to the build options (EXTRA_CFLAGS) then the compilation
complains that dl isn't used for most objects, except
now httpd finally builds clean (this appears to use dl).
I think that Apache has it's own DL functions, so maybe
this isn't the proper fix? (to link in the Linux -ldl).

Here are the relevant sections from `httpd -V' output:

Server compiled with....
 -D HAVE_MMAP
 -D HAVE_SHMGET
 -D USE_SHMGET_SCOREBOARD
 -D USE_MMAP_FILES
 -D MMAP_SEGMENT_SIZE=32768
 -D USE_FCNTL_SERIALIZED_ACCEPT
 -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
 -D USE_QSC
 -D QSC_HASH_SIZE=32768
 -D QSC_MAX_SIZE=4194304
 -D QSC_HEADER_GRAIN=32
 -D FAST_TIME
 -D BUFFERED_LOGS
 -D LOG_BUFSIZE=65500
 -D PIPE_BUF=4096
 -D NO_GRACEFUL
 -D USE_QUICK_LOG
 -D USE_STAT_CACHE
 -D STAT_CACHE_SIZE=32768
 -D STAT_CACHE_TIME=300
 -D STAT_CACHE_PATHLEN=128

Is having the "UNSERIALIZED" and "FNCTL" stuff together
a bad combination? Not sure where the FNCTL is defined.

My webserver has 2GByte memory (Linux 2.2.13+bigmem)
so I'm not sure whether the above QSC/STAT_CACHE
settings are appropriate? I have ~40k active objects
that average ~10k (.gif files) (according to Squid
which I tested -- and decided against due to latency
issues -- previously on the same servers).

Another idea I wanted to bring up is the possiblity
for an automatic or auto-adapting MMAP function aka boa
seems to have, in that you don't need to explicitly
mmapfile (which is a major pain with >40k objects,
and the object pool changing quite often.)

I really wanted to use something like Squid cache
in reverse (httpd accellerator mode) to front-end
apache but the latency was like 1 second when I tested
and it was quite a bit slower than Apache even.

Finally is there a way to run 10x-patched Apache
with the mod_ssl add-ons? Someone on this list
mentioned they'd had "limited" success on this?

Anyway glad to see someone's taken Dean Gaudet's
original work and brought it to the "next level";
seems many people have 'given up' on Apache performance
and push boa, phttpd, etc as "the solution" to Apache
when I find I still need to features Apache provides.

'twas me ...  not looked at it since my initial attempt.

There are certainly conflicts between mod_ssl and 10x.

SINGLE_LISTEN_UNSERIALIZED_ACCEPT and USE_FCNTL_SERIALIZED_ACCEPT can
coexist.  The former means it's safe for different Apache child
processes to accept() simultaneously from the same socket at the same
time if there is only one socket (e.g., zero or one Listen directives).
The latter means, if there is more than one socket, Apache must
serialize accept() calls and fcntl() is the way to do it.  See
	htdocs/manual/misc/perf-tuning.html#acceptserialization
in your patched Apache tree for an explanation of all this.

Try moving the "-ldl" from the compiler flags (EXTRA_CFLAGS) to the list
of libraries the linker needs (EXTRA_LIBS).  It's really a linker
option.

With that much memory and that many files to cache you could stand to
increase QSC_MAX_SIZE.  Watch the "Memory use / total" line on the
server-status page.  You should probably double QSC_HASH_SIZE too,
although for diminishing returns -- but again only if you're using the
QSC for all of them.  Read
	htdocs/manual/qsc.html
(especially at #status) in your patched Apache tree for what all the
stats mean, how to see them, and how to tune your server to make the QSC
run smoother.

Your STAT_CACHE_SIZE seems big.  The stat cache is really meant to be
small, and if most of the files are in the QSC the stat cache isn't
doing much anyway.  See
	htdocs/manual/misc/perf-mja.html#statcache

The rest look OK.

You're not the only one.  There is a tradeoff though, as always:
Maintaining the cache in software slows things down.  An adaptive
mod_cache is available in
	ftp://ftp.apache.org/dist/contrib/modules/1.3/apache-contrib-1.0.8.tar.gz
but I have not used it and I'm told it's buggy.

A few people, including myself, have applied both the 10x patches and
the mod_ssl patches.  Apply 10x first, then mod_ssl.  There are
conflicts you must resolve manually.  I don't know of a good way to help
everyone who wants to use both:  I don't want to distribute a combined
patch because that might ruffle feathers over in mod_ssl land, but there
are a couple of places in the combined tree that need special attention.
Anyone have any ideas?

I don't know the answer.  The only major problem should be porting
qsc_cas().  If you get the patches working on FreeBSD please contribute
your modifications to the project so others may benefit.

How to make redirect in apache ?
When apache (httpd) is called from the browser, it's read index.html.
How can i make it read my script or another file ?
Thank You

John, just change the line in your Apache configuration file that reads:
 
  DirectoryIndex index.html index.htm

And just tack on whatever filename you want to be the default.  Later.

Hi Robert, hi SGI-Apache list,

I'm browsing the archives of the SGI Apache mailinglist and found the
question about the patches and FreeBSD.

Yes, these patches can be applied to "Apache for FreeBSD" (I've tried
only 10xpatch-1.3.12-0 a while ago). It's the same Apache as for every
other OS.
If you build Apache from the FreeBSD ports collection cd into the
apropriate(sp?) directory and type "make patch" to apply a few FreeBSD
patches (non FreeBSD users interested in the patches should look into
http://www.FreeBSD.org/cgi/cvsweb.cgi/ports/www/, just click at the
apache port you are interested in and have a look into the patches
subdir). After this cd into the "work" directory and apply the patches
from SGI (as described by SGI), cd back into the main Apache port
directory and continue with the make process.

The qsc_cas function needs only porting if you decide to use qsc
(compile it) AND you are using FreeBSD-alpha, qsc and FreeBSD-x86 works
(read: compiles and didn't seqfault if you are not using the qsc
functionality. I haven't tested qsc, but I would be surprised if it
didn't work).

Bye,
Alexander.

P.S.: mja: I'm the one who send in a patch for "#ifdef LINUX" -> "#ifdef
x86" (paraphrased) in the qsc_cas code (10xpatch-1.3.9?). I thought I've
noted the fact I compiled it with FreeBSD, but I don't remember if I
really sayd it.

Hi,

I tried again to use 10xpatch-1.3.12-[0-2] with the FreeBSD port (as
described in my last mail). I had to add "|| defined(__i386__)" into the
conditional in src/main/qsc.c at line 185 (the conditional just before
the qsc_cas function):

This is incorrect.  The cmpxchg instruction exists only on i486 and
later processors.  Using this instruction on an i386 will cause an
illegal instruction trap.  Perhaps you need to define __i486__ or
__i586__ or __i686__ etc. during your build.  I did, on Linux.

It seems gcc has a bug regarding the definition of those defines.

A litte test program:
---snip--(t.c)-
#include <stdio.h>

int main(void)
{
#ifdef __i386__
  printf("i386: %d\n", __i386__);
#endif
#ifdef __i486__
  printf("i486: %d\n", __i486__);
#endif
#ifdef __i586__
  printf("i586: %d\n", __i586__);
#endif
#ifdef __i686__
  printf("i686: %d\n", __i686__);
#endif
#ifdef __pentium__
  printf("pentium: %d\n", __pentium__);
#endif
#ifdef __pentiumpro__
  printf("pentiumpro: %d\n" __pentiumpro__);
#endif
}
---snip---

The tests (the first CFLAGS setting is a subset of the CFLAGS setting
I've used to compile apache+10xpatch):
---snip---
(23) netchild@ttyp1% CFLAGS=-march=pentiumpro gmake t
cc -march=pentiumpro    t.c   -o t

(24) netchild@ttyp1% ./t
i386: 1

(27) netchild@ttyp1% CFLAGS=-m486 gmake t            
cc -m486    t.c   -o t

(28) netchild@ttyp1% ./t                 
i386: 1
i486: 1

(31) netchild@ttyp1% CFLAGS=-mpentium gmake t
cc -mpentium    t.c   -o t

(32) netchild@ttyp1% ./t                     
i386: 1
i586: 1
pentium: 1

(34) netchild@ttyp1% CFLAGS=-march=pentium gmake t 
cc -march=pentium    t.c   -o t

(35) netchild@ttyp1% ./t                          
i386: 1

>From the info page of gcc (order rearranged to explain the above tests):
---snip---
`-march=CPU TYPE'
     Generate instructions for the machine type CPU TYPE.  The choices
     for CPU TYPE are the same as for `-mcpu'.  Moreover, specifying
     `-march=CPU TYPE' implies `-mcpu=CPU TYPE'.

`-m386'
`-m486'
`-mpentium'
`-mpentiumpro'
     Synonyms for -mcpu=i386, -mcpu=i486, -mcpu=pentium, and
     -mcpu=pentiumpro respectively.  These synonyms are deprecated.
   
`-mcpu=CPU TYPE'
     Assume the defaults for the machine type CPU TYPE when scheduling
     instructions.  The choices for CPU TYPE are:

     `i386'        `i486'        `i586'        `i686'
     `pentium'     `pentiumpro'  `k6'          

     While picking a specific CPU TYPE will schedule things
     appropriately for that particular chip, the compiler will not
     generate any code that does not run on the i386 without the
     `-march=CPU TYPE' option being used.  `i586' is equivalent to
     `pentium' and `i686' is equivalent to `pentiumpro'.  `k6' is the
     AMD chip as opposed to the Intel ones.
---snip---

It seems the conditional upon which the i386 qsc_cas function is build
isn't a good solution because gcc (2.95.2 19991024) seems to have bugs
regarding the definition of the i?86 defines. IMHO it isn't good
practice to define a __i?86__ define by myself, they are reserved
defines of the compiler, so I propose the following patches:

Hello,

I am interested in using this patch, however I have never used a patch
before so I am not 100% sure what to do.

I downloaded the patches into the apache_1.3.11/src and ran 
patch < 10xpatch-1.3.11-0

then it asked me what file to patch, and I have not a clue so I told it
httpd and then got errors.. and then it asked me again what file to
patch..

So what file(s) do I need to apply the patch to?

Thanks in advance...  :)

..rick

Lets asume your apache_1.3.11 directory resides in /tmp. You have to cd
copy 10xpatch-1.3.11-0 into /tmp, cd into /tmp and then to patch from
there.

Your know apache is already at 1.3.12? And you know there exists some
Bugfixes for 10xpatch (I've 10xpatch-1.3.12-0, 10xpatch-1.3.12-1 and
10xpatch-1.3.12-2)?

Bye,
Alexander.

I've downloaded all the patches and even redownloaded
the apache-1.3.12.tar.gz and I'm still unable to apply the patches.
Here are my steps on a RH 6.0 2.2.14 system:

cd /usr/src
tar -xzvf /tmp/apache_1.3.12.tar.gz
cd apache_1.3.12
cp /tmp/10* .
patch < 10xpatch-1.3.12-0

and this yields:
[root@couloir apache_1.3.12]# patch < 10xpatch-1.3.12-0
patching file `10xpatchlevel'
patching file `ABOUT_APACHE'
can't find file to patch at input line 26
Perhaps you should have used the -p or --strip option?

There's a hint in the error message:

Some versions of patch work this way:

% gzcat apache_1.3.12.tar.gz | tar xf -
% patch < 10xpatch-1.3.12-0

Some work this way:

% gzcat apache_1.3.12.tar.gz | tar xf -
% cd apache_1.3.12
% patch -p1 < 10xpatch-1.3.12-0

I'll add this to the FAQ.  Thanks.

yay, it's the hybrid threading model.  i'm stoked that 2.0 made this easy
for you -- it's exactly one of the applications i envisioned with the mpm
architecture.

oh and it's based on NSPR.  heh.  i love how things come full circle.

thanks mike (and sgi)!

Subject: accelerating apache/QSC.


Mike,
today i stumbled upon sgi's accelerating apache project and found it
rather intriguing.  i've tried sgi's patches with apache 1.3.12
successfully and notice slightly better returns on some simple benchmarks
with apache's "ab" than with apache 1.3.12 alone.  is there a document
anywhere that documents what changes sgi has made in the patches as an
overview, or should i continue reading through the actual patch?

also, i have a question about QSC.  i have it compiled in, and it's
enabled, but for some reason every page appears to be "uncachable".
static html, static images...everything i've tried.  i've looked over the
rules in the qsc documentation about the no-cache pragma and all the steps
in order for a page to be cached, but i'm still baffled.  is there
anything i could be easily missing here?  i'm basically using all of the
apache/sgi defaults.

this is on a linux/intel system.  redhat 6.2 operating system.  i've
configured with:
CFLAGS='-DUSE_QSC -D__i686__' ./configure --prefix=/home/tcl/aptest/apache-sgi --enable-module=most --enable-module=mmap_static

the -D__i686__ is because gcc only seems to define __i386__, yet
src/main/qsc.c checks for 486, 586, 686, or pentiumpro.  so that's my hack
way of getting around that for now.  the rest should look familiar.

my server-status is showing things like:

Quick Shortcut Cache (QSC) Status:

I haven't found one last time I checked oss.sgi.com. If there's one, it
must be an SGI internal document.

It seems that's the only way... perhaps you can document what you get
out of the patch? :-)

If you use gcc v 2.95.2 you can use -mpentium or -mpentiumpro instead
(-march=... should include -m..., but it didn't), it defines it for you.

[server-status]
You haven't included relevant parts of your apache.conf (I didn't use
the QSC, so I can't comment further).

haha.  that thing is large.  seems heavily composed of (long) and other
casts for 64 bit / irix64 portability i assume, but i haven't found much
beyond that...yet...

hmm, there's not much to it.  i basically use sgi's defaults:

<IfModule mod_mmap_static.c>
    QSC on
</IfModule>

and my configure did include --enable-module=mmap_static

i've seen the mmapfile directive with mmap_static, but i was under the
assumption that QSC handles caching much more automatically and
dynamically.  if not, what are its benefits?

still baffled as to what i'm missing.

If you check out the mod page for mmap_static, you'll see a little `find`
line they note to include a lot of files within your mmapfile
directive.  It just makes me believe that this is what they want you to do
to have things cached, which seems super kludgy if that's the case for
large sites.  I can't run a huge find on all my accounts when the web
server comes up.  That's lame.  It can't be troo.

yeah but that's just for mmap_static.
qsc must have features beyond mmap_static.

Ok, but then I don't understand why I get entries in the qsc table *only*
when using mmapfile directive.

It seems to be designed for static content (which, per definition,
didn't change very often). You can do the "find" once and only add new
stuff as needed (you know when you change something, right?). You also
have to restart the webserver after a change, so you can't allow
customers to use it without notifying you (you didn't have to find
static content yourself, they have to provide a list which should be in
a format which can be processed by a script which does sanity checks and
generates config rules to be included in the config).

There's more, belive me (I ported it to 1.3.12 on my own, but I wasn't
fast enough to submit it, it was already done... and no, I didn't

Because the QSC is an extension to mmap_static.

I'm back from vacation.  Are you able to use the QSC now or may I still
help?

There's some documentation about some important functional parts of the
patches:
	http://oss.sgi.com/projects/apache/patchinfo.html#documentation
which unfortunately looks right only when viewed as part of the Apache
server documentation (in other words it would look bad standalone on
oss.sgi.com).  I won't write docs this way again; in the future all the
docs will work both ways.

There is no overview document, although I have been sitting on an
unfinished one for a year.  You can craft your own history and overview
by chasing links from
	http://oss.sgi.com/projects/apache/news.html
and/or reading each version's patchinfo page and seeing how things
progress over time:
	http://oss.sgi.com/projects/apache/patchinfo-1.3.6.html
	http://oss.sgi.com/projects/apache/patchinfo-1.3.9.html
etc.

> also, i have a question about QSC.  i have it compiled in, and it's

The other responders were correct.  The QSC is tightly integrated with
the mmap_static module.  The QSC responds only to pages that are
mmapfile'd.  See the #using and #primer sections of
htdocs/manual/qsc.html in your patched source tree.

See http://oss.sgi.com/projects/apache/faq.html#Q17

The QSC caches only responses generated by mmap_static which requires an
explicit list of files to map.  Yes this is a clunky interface, but you
don't have to mmapfile every file, just the popular ones will do.  You
don't need to use the find command every time the server starts:  mine
the logs for the most-requested static files and map just those.  Adjust
the list occasionally as part of routine maintenance.

Its benefit is about 30% faster response.

> qsc must have features beyond mmap_static.

The QSC exists only to make Apache serve HTTP GET requests for static
content faster.  For a more dynamic, self-balancing, easier to
configure, reputedly buggy, and much slower cache try mod_cache in
apache-contrib-1.0.8 from http://www.apache.org/dist/contrib/modules/1.3/ .

Please let me know if you have any other questions.

Mike,
thanks a lot for your responses.  i was just under the assumption that qsc
did something different, but now i understand it's mainly just a
performance boost to mmap_static.

ah now i even see this in the qsc docs:
You must also configure the mmap_static module by adding an mmapfile directive for each file you want cached.

missed that the first time.

thanks!

-tcl.

Two more patches for Apache/2.0a6 are available from the Accelerating
Apache Project.

Patch #1 better identifies the server as using AAP patches and the STM,
and also adds some reporting information.  Patch #2 optimizes
time-of-day queries and conversions, increasing performance 7% on my
test rig.  Patch #1 and part of patch #2 are useful only for STM users,
but the rest of patch #2 could help a wider audience.

Apache developers, as with all of the AAP's patches, please consider
adopting the time optimizations into a future release of Apache.

More information and the patches themselves are available from
	http://oss.sgi.com/projects/apache/

Two more patches for Apache/2.0a6 are available from the Accelerating
Apache Project.

Patch #3
  - Adds some features to and fixes some minor bugs in the STM,
    including a fix for bug 6531 for the STM.  It does not fix the bug
    for other MPMs since there was some doubt about whether it actually
    is a bug at all.
  - Changes the 10xpatchlevel version identification.
  - Optimizes mod_mmap_static slightly.

Patch #4
  - Optimizes logging in Common Log Format (CLF), similar to original
    AAP patch #3.
  - Fixes bugs 6519 and 6550 related to buffered logs.
  - Fixes documentation bug 6556.
  - Ports %m, %H, and %q format options from 1.3.
  - Adds --enable-speed-daemon option to configure.

Apache developers:  As with all of the AAP's patches, please consider
adopting any or all of this work into a future release of Apache.

Oh what the heck, why not.  Here's another patch for Apache/2.0a6 from
the Accelerating Apache Project.

Patch #5 adds apr_inet_ntoa(), a fast implementation of inet_ntoa(),
similar to the one from original AAP patch #3.

I'm curious if Solaris 8's NCA (Network Cache Accelerator) can work /with/
the patches.

Hi,

I'm trying to build a version of apache 2.0a6 with the state threads
patches.

I've applied the patches, run "buildconf", and tried to run "configure",
which fails because it says I don't have... state threads.

I thought they were part of the package?  Well, it seems not, since the
configure script goes on to look for "st.h" and that doesn't appear in
my patched source tree.

I downloaded the state threads code, and unpacked and built it, and sure
enough it's got the st.h header...

My question is, has anyone already figured out how to point the apache
configure/make files at the location where the state threads package is
installed?

  best regards,
     nick caruso

You must download the state threads library separately.  I'll make that
more explicit on the web site.

You need either to install st.h and libst.so into your system's default
locations (for example, /usr/include and /usr/lib, respectively) or to
set some environment variables to point to where those files are.  I
just updated the STM's user's guide to answer this in more detail.  See
	http://oss.sgi.com/projects/apache/stm.html#guide

Thanks for bringing this to my attention.  Please let me know if these
instructions help, how I may improve them, and if I can help you in any
other way.

Mr. System Administrator Man frowns disapprovingly and does not give me the

I managed, by sticking "-L" and "-I" options in everywhere I could, to
finally bludgeon the thing into compiling.  I may have had to set
LD_LIBRARY_PATH in the environment as well.  I was hoping someone knew a way
to trick "configure" into doing all this for me...

I'm trying to do a rough benchmark comparison of Apache 2.0 with your patches
and "Proprietary Web Server X", both running on an 8-processor SGI box.

Any suggestions?  I've been running a bunch of perl scripts on people's
desktop boxes, each doing a fetch of a 40k page of static HTML.  The two
servers look comparable, but 1) the times are all over the place, seeming to
imply that I'm actually measuring overhead from the desktop machines and not
the server response time, and 2) the cpu utilization on the server never
breaks 2 or 3 percent, for either web server.

   thanks and best regards,
       ncc

I don't know how to share my years of experience benchmarking web
servers in an e-mail message, but I can sum up a few shiny bits of lore
and some starting points.  First, if your server's CPUs aren't 100%
utilized you're benchmarking your clients or the network not the web
server and your comparisons are meaningless.  When I run benchmarks I
need two to four load generating clients per server CPU over a fast
network like a private 100BaseT or gigabit ethernet.  For instance, to
max out a 4 CPU Origin2000 I use 16 2-CPU Origin200s connected via 4
private GbE networks.  Double all that for 8 server CPUs.  Anything less
just won't place enough load on the server.

Requesting a single web page over and over does not accurately model
real-world loads on web servers.  The SPECweb96 benchmark requested a
large number of static files over and over and is now obsolete due to
its limited capabilities.  SPECweb99 issues both static and dynamic
requests.  Read more about them at http://www.spec.org .

There are lots of performance analysis tools available for your
unidentified SGI box.  Check out SpeedShop, osview, perfex, sar, par,
Performance Co-Pilot, xbstat, and WindView for starters.  Information
about all of these tools is available from http://techpubs.sgi.com .
Remember to tune all parts of your system:  the web server application,
the kernel, device drivers, the hardware.

Read SGI's Web Performance Tuning Guide at http://www.sgi.com/tech/web/
and SGI's SPECweb96 disclosures from www.spec.org, such as
http://www.spec.org/osg/web96/results/res2000q1/web96-20000124-03351.html
for descriptions of how to tune your system for high performance web
serving.

Since you decline to identify your "Proprietary Web Server X" I can't
quote a specific performance comparison, but I can say that the
Accelerating Apache Project's patches make a properly tuned
Apache/1.3.12 run faster than every other web server I tested on Irix
and Linux, including the latest from Zeus and Netscape/iPlanet, on the
SPECweb96 benchmark.  I'm tuning Apache/2.0 now, focusing on SPECweb99,
and I expect it to perform similarly by the time I finish.

Finally, since you're measuring the performance of an SGI machine, SGI
may be able to help you.  Contact your local SGI service representative
or SGI Managed Services and tell them I sent you.

i just saw that in 1.3.13 (unreleased), some of those sgi patches were
worked in:

  *) Merged in a small subset of SGI's latest `10x' patchkit for Apache
     1.3.11. The extracted and merged in parts are entirely cleanup and
     non-performance related changes only. SGI's remaining changes are
     not taken over, because they are either cluttering the Apache 1.3
     sources too much (e.g. the lint(1) related changes) or cause too
     much internal changes (e.g. the ap_int32 types, etc.) which are not
     reasonable to do any longer for Apache 1.3 (they should be done for
     Apache 2.0 instead).

I have just installed Apache on my server and would like to configure the
server for CGI. I have setup the httpd.conf file such that ScriptAlias
/cgi-bin/ /home/www/cgi-bin The cgi-bin directory has also been configured
for Option Includes ExecCGI. The Server Side Includes work fine, however, my
counter.cgi in that directory does not work. Apache error log shows that
"(2)No such file or directory exist".

Please help. Thank you.

This mailing list is for information and support regarding the
Accelerating Apache Project, not Apache in general.  However, I wonder
if your counter.cgi program runs standalone -- does it run successfully
from the shell as the same user and group that Apache uses?

In a story I read to my kids, only Horton the elephant (with his large
ears) hears the tiny Whos inhabiting a dust mote.  The other jungle
animals threaten to boil the mote in oil unless the Whos shout loud
enough for them to hear.  Only when all the Whos, including the very
smallest, yell together do the other animals hear and believe.  [Horton
Hears a Who, by Dr. Seuss.]

Now is the time for all you Accelerating Apache Project supporters, no
matter how small, to voice your support for this project to the ASF.  As
I announced a month ago on the project site I can't keep porting the
patches to new versions of Apache.  If the ASF adopts them into the main

(Note: I know next to nothing about the accelerating Apache patches, so what
I suggest may not be possible)

What about breaking up the patch into smaller chunks so that at least some
parts make it into the main branch?  Has anything been accepted at all to
the main tree?

At the very least, getting things like the 64-bit compatibility patches
would be useful.

I've attempted to contribute simple patches to other Apache projects in the
past (Tomcat), and found it very difficult to make any progress even when
submitting obviously correct patches.  No-one would apply the patches!  It
really requires you to get the attention a committer in the group, and only
then can you make some progress.  It seems that there is much politics and
in-fighting going on in the various Apache developer groups which is
unfortunate and scares developers away.

-Dave

I was browsing Apache 1.3.14 source tree and noticed
that it includes the expat library source (fast XML
parser).  From the src/lib/expat-lite/expat.html file:

   Copyright (c) 1998, 1999 James Clark. Expat is subject
   to the Mozilla Public License Version 1.1. Alternatively
   you may use expat under the GNU General Public License
   instead.

So much for ST's "inappropriate license" argument.
Jim Jagielski from ASF wrote on slashdot

   The Apache Web Server Group believes very strongly in the

   We just won't accept any patches to our code that are
   contributed as MPL 1.1. So the State Threads MPM must be left
   out of the tree.

Oh well, it's all moot now anyway.

Hi - I am running FreeBSD 4.3, and have a clean Apache 1.3.14 source tree,
patched with the full SGI Accelerator patch. I have set the following
compiler flags, after reading all the documentation:

  CFLAGS=-DUSE_QSC -DSPEED_DAEMON -DUSE_DIRECT_IO -O2

I then run "./configure --enable-module=mmap_static --enable-rule=IRIX64"
to add the options I need. Then I run "make" of course, and the
compilation fails at this point:

Given that I'm not a C coder, can anyone help me with this? I'd like to
get this working as soon as possible, to experiment with it.

Thanks for your help

I compiled it a long time ago on FreeBSD, and I can't remember every
step, but I definitivly didn't used "--enable-rule=IRIX64".

I also didn't configured it myself, I used the ports framework (make
patch in the ports directory, applied the SGI patch, modified the
port-makefile (CFLAGS+=-DUSE_QSC ..., added --enable-module=mmap_static
to CONFIGURE_ARGS), make)). This also enables the use of the accept
filter (you want to add it to the kernel or to load the kernel module).

Bye,
Alexander.

FWIW, I tried it this way, going via the ports system, but I got exactly
the same compile failure, in the same place. I'm really not sure what else
to do, other than hacking some code, but that's beyond my realm!

Thanks anyway

Subject: 10x patch breaks modules in 1.3.20
X-Mailer: VM 6.89 under 21.1 (patch 14) "Cuyahoga Valley" XEmacs Lucid
Sender: owner-apache@oss.sgi.com
Precedence: bulk

I have a couple of Apache modules that are content handlers, running
under Apache 1.3.20 on Solaris 2.8 (sun4u sparc SUNW,UltraAX-i2).  The
modules are dynamically loaded.

However, installing the 10x patch breaks the modules. This is the
sysmptom: in the handler,

static int foobar_handler(request_rec *r)
{
    const char* uri;
    const char* args;

    ...

    uri = r->unparsed_uri;
    args = r->args;

    ...
}

I get a NULL pointer for r->unparsed_uri, and an empty string for
r->args. The unpatched 1.3.20 works fine. What was it that broke this?

I have a suggestion: break up the patch into smaller pieces. In my case,
for instance, I'd like to use QUICK_LOG and the stat cache; but I'm not
serving any static content, so QSC is of no interest to me. And I'm not
on Irix, so Direct I/O is similarly superfluous. There seems to be no
reason these can't all be different patches, they seem quite orthogonal.

(Some of the things I've tried, in desperation: turning off all the
extra features; as well as editing the patch file by hand - very
tedious! - to not include the QSC and Direct I/O bits. So far no luck.)

Something must have changed between 1.3.14 and 1.3.20 in the way these
fields are initialized.  Since I have no direct experience with 1.3.20 I
can't help you.  Anyone else?  If you have the same problem with 1.3.14
I'll help you.

> I have a suggestion: break up the patch into smaller pieces.

First of all, the patches were originally split into smaller pieces.
The smaller ones went over about as well as the monolithic ones so there
was no point in continuing them.

Second, even if split the patches depend on one another.  More
accurately, they all depend on the 64-bit and warning-free changes.
This makes them hard to maintain separately from one release to another.
The changes are easier to port as a group.

Third, all the major pieces are #ifdef'd already.  If you don't want a
particular enhancement, just undefine its token.

Fourth, the project is terminated so it ain't never gonna happen.
Sorry.

After a lot of exploration with gdb I found that I was compiling the
modules against the unpatched 1.3.20 - D'oh!

So scratch the problem report; modules seem to work fine with the 10x
patches.

Any results of this combination/process documented somehwere?

I've had great success not including mod_ssl.  I've also tried my best
to incorporate all the mod_ssl patches by hand after 10x, but still
ran into a few problems -- especially with the way the 10x patches
modified buff.c.

~750 requests per second (ssl, no 10x - ab) compared to 3000+ requests per
second (non-ssl, x10 - ab) is a performance gap I'd like to close a
bit it at all possible.

All suggestions welcome and appreciated.

Apply the 10x patch first, then the mod_ssl patch.  Identify the
conflicts.  For each conflict, examine the corresponding parts of the
10x patch and mod_ssl patches individually to determine the reason each
changed that code.  Then merge the conflicts by hand.

For example, the 10x patches rewrite sections of buff.c to make better
use of writev.  The mod_ssl patches modify the same sections to
redirect network I/O system calls through ssl wrappers.  These conflict,
and the answer is to edit the code yourself to honor the intent of both
patches.  Where 10x changes write to writev, you must change the mod_ssl
modification similarly.

I recall there being only one or two places requiring any thought.  The
rest should be fairly straightforward.

Not being a Linux programmer, I can only go on bits and pieces I pick
here and there.  The 10x buff.c changes really threw me for a loop.  I
couldn't / still can't figure out where to put the relevant mod_ssl
changes (listed below) after the 10x patch got through with it.

+ #ifdef EAPI
+           if (!ap_hook_call("ap::buff::writev", &rv, fb, &vec[i], nvec -i))
+ #endif /* EAPI */

The function these lines were supposed to be placed in was completely
changed to all of one line by 10x.

These are the problems I'm trying to overcome at the moment:

buff.c: In function `writev_it_all':
buff.c:1113: `rv' undeclared (first use in this function)
buff.c:1113: (Each undeclared identifier is reported only once
buff.c:1113: for each function it appears in.)
buff.c:1113: `i' undeclared (first use in this function)
buff.c:1116: warning: control reaches end of non-void function

Totally lost here.  Tried moving the three mod_ssl lines around w/o
success.  Also tried renaming &rv to &rval which didn't help.
Obviously I haven't found the magic position and/or modifications for
these lines.

Yes, I had figured the same.  By comparing the original sources and
both 10x and mod_ssl patches, everything seemed pretty simple to fold
in -- except the mod_ssl buff.c related modifications.

Thanks for the response.

A merge of accelerated Apache/1.3.20 and mod_ssl 2.8.4 is now available
for your reference.  You still need to download all the components and
follow mod_ssl's instructions.  The merge is simply to help resolve the
patch conflicts.  Hope this helps.

Hello Mike,

The effort is very much appreciated!

However, the patched version compiles fine, but is very unstable for
me on a RHL 7.1 x86 box (all updates).  The logs show "successful"
negotiation and content serving to the client.  No error messages, no
segfaults, no core dumps.

The problem I'm seeing seems to be some sort of an unexpected / early
disconnection of the browser from the webserver.  I've tried IE & NS 6
(SSLv3) on WIN2k and Mozilla (TLSv1) & Konqueror 2.1.1 (SSLv3) under
X11  (same box the webserver resides on).

For example, the initial "You succeeded in installing the software"
screen loads fine on all browsers that I've tried.  Going beyond that
is pot-luck.

NS6 can't get beyond that page (no errors, just doesn't move when you
click on a link).  IE 6 can only get to chapter 3 of the mod_ssl
manual and bits of the apache manual (rest produce the infamous MS
"DNS Error".  Mozilla can't get beyond the initial page (same as NS6).
Neither can Konqueror (which reports "connection to host is broken"
when trying to proceed beyond initial page).

All browsers are properly served a 404 or 400 error page.

I've tried compiling against the pre-installed RH OpenSSL libraries,
and also against freshly downloaded / configured v0.9.6b sources.
Doesn't seem to make a difference.

Compiling w/o the 10x patches produces a fully working mod_ssl enabled
server, and the exact same logfile content (!).

I'm following the mod_ssl instructions exactly, including mm-1.1.3.
Any ideas where I'm going wrong?
