open2() write doesn't go anywhere
Sorry if this is already somewhere in the faq or just plain stupid, but I
couldn't find any satisfying answer or workaround to this. When I do
something like:
--
use IPC::Open2;
...
if($state->{pid} = open2(my $rx,my $tx,'/usr/bin/ispell','-S', '-a')) {
$state->{header} = scalar <$rx>;
...
}
...

Under modperl, I can see the other progam sending data back (checked Ispell,
but also did some diagnostics with others), but the mod_perl program seems
not able to send *anything* over the $tx descriptor to the other end. Tried
this with 1 MB of junk and a 'tee -a /tmp/anything' to see if this is a
buffering issue. The file is created by tee, but no data present on STDIN.
Funny thing is that the whole thing *is* working under regular perl 5.6.0.
In the list archives, about a year ago there was a similar discussion
betweeen Richard Timuss and Doug. At some point it was said that this was
addressed and fixed in cvs
(http://www.mail-archive.com/modperl@apache.org/msg05632.html).
Current setup is perl 5.6.0, Apache 1.3.20, mod_perl 1.25, but also tried
downgrading to apache 1.3.19, mod_perl 1.24, 1.24_01 and todays snapshot
(20010612). All with the same problem.
Any ideas where to start searching?
Thanks,

mod_vhost_alias / ProxyPassReverse problem
Hi,
I have a mod_perl backend listening on *:81 and a proxy in front of it
listening on *:80, both using mod_vhost_alias configured with
VirtualDocumentRoot /www/site/%0
i.e. www.mydomain.com will have /www/site/www.mydomain.com as it's document
root. The frontend has
RewriteEngine On
...
RewriteRule \.(jpg|png|swf|css|html|txt|cgi)$ - [last]
RewriteRule ^/(.*)$ http://%{HTTP_HOST}:81/$1 [proxy]
Now this all works fine except when a client side redirect using meta
http-equiv tags occurs, in which case the hostname part in the url holds a
:81 suffix, effectively bypassing the proxy. Now, the problem is I cannot
use ProxyPassReverse because it doesn't eat hostnames as its first argument.
What's the advisable thing here? Should I consider hacking around in
src/main/util_uri.c? Can this be fixed by a fixup handler (maybe replacing
r->uri_components->port?) Or should I just drop mod_vhost_alias on the
backend and start using perl sections to do a directory scan on /www/site
and setup all my VirtualHosts that way? Has anybody done this before?

Consider changing your naming scheme to band.asp/134 and get your id from

Scheduling an Apache child for termination/influence MaxRequestsPerChild counter
Hi, I wonder if it's possible to somehow alter Apache's internal counter matched against MaxRequestPerChild or schedule the launching of a new child from withing mod_perl. The reason I want to do this, is that in the administrator section of my website, quite some stuff gets cached from the PostgreSQL backend on a per process basis and there is really no use to keep all those caches after the administrator hit the logout button. Plus, I want to be able to terminate a process if some kind cache inconsistency is detected. I know it's better to track the origin of that inconsistency and fix it there, but I'm using some modules which I did not create myself and I'm not planning to dig into 5000+ lines of code I did not wrote. What I really would like to do is to just finish the current page, dropping a line like "things are getting fishy here", wipe the administrator's session cookie and let the child die. Ime

Re: Apache::ASP rand, srand and fork...
| Yes, perl doesn't reset the 'random generator initialized' status on | fork, which it arguably should: For normal perl I can agree that fork() doesn't do something magic with the pseudo random generator and just makes an exact clone of everything. Most of us will only do expicit fork() with a good reason and concept in mind. But for mod_perl, things are different. It's not the perl fork() call, but Apache doing that. Using fork() is known to be a bad practise in mod_perl. As one can't control when Apache will fork() or kill a process, one can't tell which child will deal with a particular requests, I think rand() should line up and shouldn't be predictable also. To my opinion, it's up to the mod_perl wrapper to take care of that. Ime

Apache::ASP rand, srand and fork...
Hi,
OK, I have nailed down a second major headache I suffered from last week:
authentication keys for server generated emails which did appear to be not
as random as I hoped.
It seems that within Apache::ASP (probably mod_perl) the pseudo random
number generator (rand) is not reinitialized (srand) when Apache forks a new
process, so each child generates the same sequence of numbers using rand. In
Apache::ASP 2.03, I can see
/usr/lib/perl5/site_perl/5.6.0/Apache/ASP.pm 510:
# Ken said no need for seed ;)
#unless($Apache::ASP::RandSeed) {
# my $seed = $$.time;
# $self->Debug("seed srand with $seed");
# srand($seed);
# $Apache::ASP::RandSeed = 1;
#}
commented out. It's not the first time I hear that playing around with srand
is bad, even perlfunc mentions that. Can anybody explain to me the reason?
Shouldn't this srand thing actually be done somewhere in mod_perl?
Test page is at http://194.109.252.12/test/random.asp , running
Apache/1.3.12 (Unix) mod_perl/1.24 on Linux 2.4.0-test8, perl5.6.0.
MaxRequestPerChild is set to 10, so it won't take too long.

Re: [slightly OT] cache refusal problem with IE, http headers
| > 8 Content-Length: 294 | > 8 Content-Length: 327 | How come that the sizes are different?

Ime
Re: [slightly OT] cache refusal problem with IE, http headers
OK, did it the hardway: after a lot of tcpdump -i -s 500, grepping and stringing, I tackled it. Halfway. IMHO, it boils down to both a IE bug and a somehow 'hidden' feature of Apache. It seems that on script execution an extra header "Vary: Host" is sent to the browser. This is what the RFC's say: "A Vary field value consisting of a list of field-names signals that the representation selected for the response is based on a selection algorithm which considers ONLY the listed request-header field values in selecting the most appropriate representation." http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.44 So a "Vary: Host" would tell the browser that it can assume the content to bee static as long as the 'Host' header in a HTTP request doesn't change. Appearantly, this header is misinterpreted by IE, causing it to get everything fresh from the server causing the onmouseover delays. I suspect Microsoft of being just too lazy to even evaluate the right hand side of the Vary header. Apache docs mention about "CacheNegotiatedDocs", but that doesn't seem to get rid of the Vary header. I did a quick and dirty fix for the moment by compiling Apache with --enable-module=headers and a "Headers unset Vary" in httpd.conf, but there should be a better way. Suggestions are welcome. Ime

Re: [slightly OT] cache refusal problem with IE, http headers
| In your Apache::ASP version, try setting Expires to tell IE

I did that. And and also tried
$r->add_header('Expires',HTTP::Date::time2str(time+86400)); in a normal .pl
file. In fact, the first header dump in my previous message shows the header
doing it that way.
Other things I tried:
* "Cache-Control: public" (defaults to 'private' in Apache::ASP)
* Killing the Cache-Control header all together
* "Last-Modified:", tried in 5 minutes, in a month, in a year (the maximum
according to HTTP/1.1 standards), somewhere in 2038.
* "Expires:", idem dito
* Minimal header (just content-type and length)
* Telling IE (both 4.01 and 5.5) to *Never check*
IMHO, that last one is the weirdest of all.

[slightly OT] cache refusal problem with IE, http headers
Hi,
I tried to nail this problem down for over 6 hours now. I use GD.pm to
dynamically generate images used in a dynamically generated Apache::ASP
page. Each image is given a name which is unique (in fact: a md5 on the
original name, width, height, color depth). Some of these images are used in
a javascript onMouseOver. The images are send out to the browser via a
script, with the unique id as $ENV{PATH_INFO}.
Now the odd thing is, both IE's I tried (4.01 and 5.5) seem to /refuse/ to
cache the image oppsed to all Netscape versions, which handle things like
expected. After searching deja, I found out that more people had this
problem, but I only read about javascript preloading and stuff. That's
already been taken care off. If I take a copy of those images and let Apache
handle the request directly from disk, everything is ok.
So I started to get suspicious about headers. I thought maybe IE was choking
on the session-id cookie from Apache::ASP, so I rewrote the Apache::ASP
gateway to plain mod_perl. I messed around with headers, even read
http://perl.apache.org/guide/correct_headers.html three times, but nothing
fixed my problem so far.
I know the problem is not really mod_perl related. I agree on the fact that
this is probably a typical Microsoft inconsistancy. Maybe some of you have
had the same problem.
Below is a sample of the headers it returns. Any ideas? Anything that is
communicated without me seeing it?
Thanks,

Re: VBScript::Parser

VBScript::Parser
| Well you still have to implement a VBScript parser (Damian, of course, | implemented a latin parser), and the problem is that ASP is parsed by | Apache::ASP, not by perl, so you'd have to make use of the VB parser at | that point. Hi, just wanted to let you know, I'm going to pick this up in about one or two weeks from now, as soon as I tackled some deadlines. In short, I have the following in mind and partially worked out in actual code. A package VBScript::Parser which offers: $parser=new VBScript::Parser; $evalable_perl_code = $parser->parse($complete_asp_page); The evalable_perl_code will start with a "$VB=new VBScript::Core;". All VBScript statements will have to get a perl method in the VBScript::Core package, so a=mids(x,y) could be translated to $a = $VB->mid($x,$y). I could definitely need some help in creating methods for all statements in VBScript. All Server, Request, Response and Application objects will inherited from Joshua's Apache::ASP. After that, we could create other objects like VBScript::adodb::connection to implement things like "server.createobject(adodb.connection)" and the like. Let me know if you're interested to help me out with this. Ime

Re: VBScript parser (was Re: Apache::ASP Question)

Re: mod_perl, mod_rewrite, package namespace
Hi, I just wanted to let you know that (once again) re-RTFM the manual *twice* solved my muliple compilation problem. The solution is adding [PT] to the RewriteRule. RewriteRule ^/query/(.*) /query.pl?$1 [PT] -- http://www.apache.org/docs/mod/mod_rewrite.html: 'passthrough|PT' (pass through to next handler) This flag forces the rewriting engine to set the uri field of the internal request_rec structure to the value of the filename field. This flag is just a hack to be able to post-process the output of RewriteRule directives by Alias, ScriptAlias, Redirect, etc. directives from other URI-to-filename translators. A trivial example to show the semantics: If you want to rewrite /abc to /def via the rewriting engine of mod_rewrite and then /def to /ghi with mod_alias: RewriteRule ^/abc(.*) /def$1 [PT] Alias /def /ghi If you omit the PT flag then mod_rewrite will do its job fine, i.e., it rewrites uri=/abc/... to filename=/def/... as a full API-compliant URI-to-filename translator should do. Then mod_alias comes and tries to do a URI-to-filename transition which will not work. Note: You have to use this flag if you want to intermix directives of different modules which contain URL-to-filename translators. The typical example is the use of mod_alias and mod_rewrite..
mod_perl, mod_rewrite, package namespace
Hi,
I have a script which takes some input variables in the QUERY_STRING, let's
say:
http://localhost/query.pl?archive=1&chapter=2§ion=3&subsection=4
This is working fine from the user perspective. But, I found out that most
search engines just discard the querystring, so my site won't get indexed.
Besides of that, urls are quite ugly this way. So what I want to do is do
some mapping between canonical urls and actual scripts on my server, so from
the users perspective, there would be:
http://localhost/query/archive/chapter/section/subsection
To achieve this, I tried both
AliasMatch ^/query/ /path/to/query.pl (and let query.pl do a
split(/\//,$ENV{REQUEST_URI}))
and
RewriteRule ^/query/(.*) /query.pl?$1(and let query.pl do a
split(/\//,$ENV{QUERY_STRING}))
These both seemed to work fine, untill I was facing a ps with some 90MB
httpd processes laughing at me. After reviewing /localhost/perl-status it
got clear to me. mod_perl obviously compiles scripts in a namespace derived
from the original REQUEST_URI, so query.pl gets compiled for each and every
combination of arguments.
Does anybody has some pointers on how to get mod_perl to compile query.pl
only once? Maybe by specifying the package namespace manually from within
httpd.conf instead of letting mod_perl do the job based on REQUEST_URI?

Re: Error in running apache::asp, part 3
| [error] Undefined subroutine &Apache::ASP::handler called. | what does it mean? | How to fix it? Considering the errors you posted the past hour, I think something went wrong during the Apache::ASP installation. Consider installing Apache::ASP once again with the cpan installer (possibly use force install) and examine the output very carefully for missing dependencies. My experience is that most of the time a single "install Apache::ASP" in cpan isn't sufficient and the installer doesn't seem te resolve all dependencies right automatically, so you have to do some things manually on a really clean system. And... don't forget to restart your mod_perl enhanced Apache after that. Ime
Re: Apache::ASP #include virtual loses variables
| Well, I would like to suggest that you consider including in the Apache::ASP distribution, so that included files use the | same namespace. It doesn't make sense logically that include virtual | behaves differently from include file (other than the way the | filename/pathname is interpreted, of course). It does make sense to me, though. Consider one having very big (say 50k) include files being included from several other (say 100) scripts. Just sucking them in each script doing the include would cause *every* script growing by at least the size of the include. Now as Apache::ASP caches all compiled scripts, this would result in each httpd process growing by 50kB x 100 scripts = 5 MB, holding 98% redundant data. Giving each include a different namespace (or more accurate: compile it as a unique sub(), and thus having it's own lexical scope), will cause the include file being compiled and cached only once.

| There are two reasons why I don't like doing it this way:
|
| (1) The URL is no longer human readable.
Consider putting this dirty hack in your httpd.conf:
AliasMatch ^/database/.* /path/on/your/server/to/database.asp
And then have your script database.asp do
my @whereami = $ENV{REQUEST_URI} =~ /^database\/(.*)/o ? split(/\//,$1) :
();
This way, you can request http://yourserver/database/a/b/c/d and have
everything handled by one Apache::ASP script and @whereami will hold
("a","b","c","d")

So if your DocumentRoot is '/usr/local/etc/apache/htdocs' and your eg directory with examples from Apache:::ASP resides there, save this file to '/usr/local/etc/apache/htdocs/eg/.htaccess .

I think you have a point if you're writing stuff which is going to get a million or so pageviews a day. In that case, you'll probably have a pretty good insight in how things are going to be in advance and you can spent some valuable time into thinking out every aspect of your application before you actually start coding. I think the big bonus of Apache::ASP (or one of the other embedded perl implemententations) is that one can start working on a project with a very ugly looking functional implementation of what you want and later add (or let other people add) layout to it with their very nice HTML design tools out there, like DreamWeaver and other kick-ass Macromedia products even I like to work with. With Apache::ASP, I can work together with people who have great skills in using visual HTML editors but think they see line-noise when they actually see perl - as long as they leave the asp tags alone. Before this, we had to develop the complete design of a website and then in the end wrap the HTML in perl scripts. In case of any change in design or restyle, everything had to be done all over and there I was cut/copy/pasting everything all over. In my opinion, using Apache::ASP instead of doing old fashioned scripts, greatly reduces the time taken to complete a project, especially in those cases where you have to work on something with a lot of people and you don't know exactly what the finished project is going to be like until it's actually finished. This indeed has some drawbacks in performance. But hey, processor time is getting cheaper each day. If you're really aiming for speed and performance, there's always the option of rewriting and optimizing when your product is finished using non-embedded perl, C or, if you're a real die hard, even ASM. I would prefer buying another Pentium box, though. Except for some very busy sites, you'll probably don't care about a few extra milliseconds. Selects on databases which have grown out of proportion or have a bad structure were a far bigger slowdown than the use of Apache::ASP in most things I've seen so far. Now for the non rational part, consider this: just because Apache::ASP was out there I was able to convince some of the most nasty M$ IIS-addicted people I work with that Apache+Perl is a very good alternative for IIS. It isn't that much of a change if people won't have to change their way of thinking and can continue using their existing skills and tools to develop a website. For most website developers switching from VBScript ASP to PerlScript ASP is just a matter of learning some basic rules and grammar. Consider this - rather unethical - issue too: The main problem I had with people who are more into marketing then into technical stuff (say: managers) is that every time I tried to convince them in using someting non-M$ for a new project, I would have a terrible hard time. Thanks to Apache::ASP, I can make them dream on while they see *.asp floating around all over the place, but don't know what's really going on. Until the complete product has proofed to work - and then suddenly they don't care anymore if they find out there is no M$ box at the other end of the wire ;P Bottomline: Apache::ASP made me really happy because now don't have to develop for IIS anymore and I can stick to my Linux environment. I can concentrate on real scripting and let other people without any scripting knowledge focus on creating the HTML and layout. Ime

One way or the other, you are not going to get the security you want. And then again: if you just think how easily badly coded perl scripts (which will work perfectly fine as a strict CGI) can become a major pain in the ass (memory leakage, resource exhaustion) in a mod_perl environment, I wouldn't trust anybody without prior verification of their coding abilities in such a virtual hosting environment in the first place. | So, does anyone have suggestions on how to do suid for ASP scripts?

Otherwise, rethink your concept and see what can be put in a real database. | Wouldn't this require running one web server process for each user? I may | be wrong, but it seems to be simpler to just suid their scripts. Yep. But that's the only way you are going to have a real secure setup. Ime
Re: cgiwrap for Apache::ASP?
| I also have ASP installed, and I'd like to be able to transparently suid | the .asp scripts too. Do you know how I could go about doing this? I think this is a general bad idea. The only purpose of running scripts via a suexec or setuid mechanism I can think of is to stop different users & websites running an the same httpd digging and interfering in each other's data and files. As Apache::ASP is built on top of mod_perl which takes advantage of *internally sharing & caching* as much as possible between httpd processes, doing setuid scripts would not fix the problem. I'm not into the gory details, but I guess what you have then is the same access to the same data as before, you just have another uid. So for disk i/o this is ok, but to shield users from messing up each others mod_perl namespace in case they have a bad coding style, this is useless. If you're not trusting the people making websites and you're looking for a virtual hosting solution, I think some postings earlier this week about proxying requests to a user-dedicated apache listening on localhost is the best solution.

Re: Apache::ASP problem running the example.

Apache::ASP and gzip/inflate compression
Hi,
I would like to apply gzip or inflate compression on the response from
Apache::ASP, because my application generates a lot low-entropy
table-structures which can be compressed down to 90-95%. On a normal CGI
script I would do something like:
print "Content-type: text/html\n";
print "Pragma: no-cache\n";
if($ENV{HTTP_ACCEPT_ENCODING} =~ /gzip/) {
print "Content-Encoding: gzip\n\n";
print Compress::Zlib::memGzip($out);
} else {
print "\n";
print $out;
}
where $out sucks up all the output during execution. I can't get it to work
with Apache::ASP, though. As Apache::ASP internally buffers all the output,
my first (bad) guess was to put a kind of wrapper on the $Response->{Buffer}
object in Script_OnEnd in global.asa, which failed. So I guess there should
be a better way...
Anybody has some pointers?

Hi,
There is a HTML tag for it, but as far is I know it isn't really part of the
W3 standard:
Put this in your document just between and and for MSIE 4+
and some of the newer
Netscapes, this will set the global font, even within tables.
I think implementing something like a $Response->{FontFace} tag or the like
which automagically inserts tags after each
tag is a general bad idea, because it can easily break things and it
won't produce good HTML, because then you also should make Apache::Asp to
also insert closing tags, meaning it should have at least some sense what is
going on, causing everything to slow down. If some browsers (especially
Netscape) already give very unpredictable results if one messes a bit with
the closing order of tags (try to do a BoldItalicPlain and see for yourself), I
think you would agree on me.
