Re: [ANNOUNCE] OpenFrame 2.05
Jonas Liljegren sent the following bits through the ether: I checked it out from CVS. But there is no INSTALL file. Right, there is however a lib/OpenFrame/Install.pod which I've just updated to clear things up. I guess we should copy the text to INSTALL to make things clear. The Apache stuff still hasn't been fleshed out. I guess I should do some Apache configuration or run a custom HTTP server. But I can't find anything about it in README or FAQ. You can run the examples (which use the standalone HTTP server) after making install which should give you a good idea of how things work. What will happen if I do a make install? The Perl modules get installed. Nothing else. It's just an application framework: you have to build the rest. However, it isn't hard. For example, go into examples/hangman2/ and run ./hangman2 for a full (fun!) example using sessions and TT2. But I'm still havenn't a general picture of the principle design. Right. I guess OpenFrame.pm should contain a top-level description of how it all works. I'm going to turn the examples into walk-throughs as that'll help too I imagine. It feels like too much module documentation to read before I have decided if I would liek to realy try it out. It's not *that* much work: % cvs update % perldoc lib/OpenFrame/Install.pod % make install % cd examples/hangman2/ % ./hangman.pl Try it out and tell us what you think ;-) Leon ps thanks for you comments -- .sig.at.home

too many files open
HiI usethe perl sub below to create
thumbs with image magick on my mod perl server andnever really had any
problems with it. I put it on another server and aftera short while it
froze up the server with this error.too many files open.
It is running under a mod-perl environment because
in doing so I am also able to rename images at the same time.
I know that because it is running under a mod perl
environment, the lifetime of the script is until roboot of server orrestart
of apache.
The freezehappend on one of the lines in
this sub so I'm thinking I'm not doingsomething right and leaving files
open.I don't think this is a result of the problem with the server.I
would appreciate if someone would look at it and tell me if it is ok or not or
give me some suggestions to prevent this problem in the future so that I can
continue to run it in mod-perl.
Perlmagick claims that it handles all of the file
handling.

This one mainly incorporates * support for HTTP Keep-Alive feature, * support for HTTP HEAD requests, * global and per-run time limits, * accurate tallying of sent, good, and failed requests (previously these were fudged) * a few small bug fixes. Please see the Changes file for complete details. Happy benchmarking! -Adi
Multiple Sites
Hello, I have the need to create 10 web sites off my Apache web server. I do not want to use 10 IP addresses. So I am doing to cheeze and do a URL/directory/index.html foreach site. Then I would give each customer a URL of URL/directory and I would like the index.html or the default.html to come up. But it does not. I edited my conf file to this IfModule mod_dir.c #DirectoryIndex index.html DirectoryIndex default.htm /IfModule But but it does not work. But if I put in URL/directory and a forward slash/ eg. http://URL/directory/ then it shows the default.htm page. But I know my customers, and they will not put in the directory forward slash. How do I get around this issue? Thanks Scott Purcell

Re: Multiple Sites
Try setting your directory index like this... DirectoryIndex default.htm index.htm default.html index.html this should catch any one of the four files as the index when you enter http://URL/directory. Also, make sure directory is in your http root path. See the httpd.conf file if you're not sure what your root directory is.

delayed file uploads...
i have a simple question. im not sure if there is a mod_perl directive or module for this but id like to perform this simple task: two web pages run in sequence. the first page, id like a user to select several files from his/her machine for uploading to the server using the input type file tag. when the user requests the next page, i DO NOT want the files to immediately transfer (many reasons for this, just a hard requirement). rather, id like to store the names of the files into a cookie or save it on the server with apache::session. this part I already have working, and am storing the file names into a tied hash using apache::session module. then the user moves onto the second web page and populates more form fields with additional information. upon submitting this second form, the files from the previous web page (names stored in the hash %session from apache::session) are then sent to the server. im not sure whether or not this can be done, anyone have any clues?

[OT] mod_gzip configuration
Hey gang, I have just installed mod_gzip on my mod_perl server and am very impressed with its performance. However, I've noticed that it is only compressing mod_perl output when parameters are passed to the script in the URL. E.g: http://www.mysite.com/test.cgi?test=1 will be compressed, but http://www.mysite.com/test.cgi will not! :-( My mod_gzip config follows: ## BEGIN MOD_GZIP CONFIGURATION LoadModule gzip_module modules/ApacheModuleGzip.dll mod_gzip_on Yes mod_gzip_minimum_file_size 300 mod_gzip_maximum_file_size 0 mod_gzip_maximum_inmem_size 10 mod_gzip_keep_workfiles No mod_gzip_temp_dir E:/Apache/temp mod_gzip_item_include file \.html$ mod_gzip_item_include file \.pl$ mod_gzip_item_include file \.cgi mod_gzip_item_include mime ^text/.* mod_gzip_item_include mime ^httpd/unix-directory$ mod_gzip_item_include handler ^perl-script$ mod_gzip_item_include handler ^server-status$ mod_gzip_item_include handler ^server-info$ mod_gzip_item_exclude file \.css$ mod_gzip_item_exclude file \.js$ mod_gzip_item_exclude mime ^image/.* mod_gzip_dechunkYes ## END MOD_GZIP CONFIGURATION Can anyone advise me as to how to change this configuration so that compression will work with or without parameters?

Then let the user select the files, click submit on the parent window, then on the subsequent page, have the parent window issue a child.form.submit or something similar with javascript...

Here is a hackish option: place the input type=FILE field in a separate frame using IFRAME or FRAME. then: a.Use Javascript to set the onSubmit action to send the filename. b.Use Javasciprt to set client side cookie

?!
Yet, there is no obvious error in your code that should drive you system
crazy. So, there are some suggestions (in addition to the questioned one
above :) that could make your code behave nicer:
- - do check error codes returned by PerlMagick!
- - globing? use it just at home ;-] in fact enhance your program using some
MIME module to detect properly the file type + check out for files like
'foo.jpg' that in fact is an animated GIF file so you will get an entire
group of output files instead of one etc...
- - you will surely gain lots of cpu time if avoiding that rotation stuff***
- - use File::Spec for constructing file paths in a portable way
- - you may wanna use some thumbmakeronly module :)) : Image::GD::Thumbnail
if that gaussian blur it's not so important ;-]
*** as I see it you need some thumbnails size normalization so: how to avoid
image rotation and re-rotation?
example:
my ($w,$h) = calcGeometry($image-Get('width','height'), 50, 50);
$ret = $image-Scale( width = $w, height = $h);
warn $ret if $ret;
sub calcGeometry {
my ($w,$h,$stdW,$stdH) = @_;
if($w$h) {
$h = $h/($w/$stdW);
$w = $stdW;
} else {
$w = $w/($h/$stdH);
$h = $stdH;
}
return int($w), int($h);
}

RE: Multiple Sites
From the start o' the thread: But if I put in URL/directory and a forward slash/ eg. http://URL/directory/ then it shows the default.htm page. But I know my customers, and they will not put in the directory forward slash. How do I get around this issue? This isn't really a mod_perl issue, it's common to all of apache. Even though this isn't in the scope of the list, here's your problem and answer. When you request a file from the apache web server. URL/something and something doesn't exist AND a directory exists under the same name, httpd sends the client a redirect to SERVER_NAME/something/ thus removing the need for people to type the trailing slash. (the server figured out if you need it, and adds it if neccesary, magic eh?) What you need to do is ensure that the ServerName directive in httpd.conf is indeed resolvable, because that's what the client's going to be looking for whenever httpd needs to redirect the client to itself. Sometimes people use the IP address (ugy imho), typically I use the domainname without the www, just because I hate typing. As others have aluded to, if you're trying to serve multiple domains (or hostnames) off one IP, you use a system called software virtual hosting. HTTP/1.1 Supports the Host: field in the http header to resolve to the site domain. Here's the config for the truly lazy (at least it worked for me) NameVirtualHost IP.address.goes.here VirtualHost IP.address.goes.here ServerAdmin DocumentRoot ServerName This is the part that's causing the redirect problem above ErrorLog CustomLog ... ErrorDocument ... ... Aliases ... ProxyPasses ... Any other config oddities ... /VirtualHost Of course all of this is in the httpd guide http://httpd.apache.org/docs/ Search @ http://search.apache.org/docs/ -A -Original Message- If you only have one IP and want to have many web sites (ie URLs) for your customers, then why don't you use VirtualHost.
