incubator-pagespeed-mod's Introduction

mod_pagespeed

CI	Status
Travis

mod_pagespeed is an open-source Apache module created by Google to help Make the Web Faster by rewriting web pages to reduce latency and bandwidth.

mod_pagespeed releases are available as precompiled linux packages or as source. (See Release Notes for information about bugs fixed)

mod_pagespeed is an open-source Apache module which automatically applies web performance best practices to pages, and associated assets (CSS, JavaScript, images) without requiring that you modify your existing content or workflow.

mod_pagespeed is built on PageSpeed Optimization Libraries, deployed across 100,000+ web-sites, and provided by popular hosting and CDN providers such as DreamHost, GoDaddy, EdgeCast, and others. There are 40+ available optimizations filters, which include:

Image optimization, compression, and resizing
CSS & JavaScript concatenation, minification, and inlining
Cache extension, domain sharding, and domain rewriting
Deferred loading of JavaScript and image resources
and many others...

incubator-pagespeed-mod's Issues

Do not warn on 'Failed to create or read input resource'

E.g.

 [Sat Nov 06 22:25:48 2010] [warn] Failed to create or read input resource /j15/templates/system/css/system.css

This is at best an "info" severity and probably could be eliminated entirely.  
It occurs in the combine_css filter whenever an input CSS file is not in the 
cache, either because this is the first time it's been seen, or because the 
input CSS file was not cacheable in the first place.

Original issue reported on code.google.com by [email protected] on 8 Nov 2010 at 12:07

Do not warn on "Invalid url relative to..."

This happens whenever a resource is loaded from another domain that the site 
owner has not authorized for rewriting.  The warnings clutter the logs and 
possibly reduce performance due to disk pressure.

We can, however, increment a statistic so we know the weight of the resources 
served from external sources.

Support Windows Apache

not really a problem, more of a feature request, but would love to see this mod 
running on WAMP systems as well.

insert_img_dimensions not detecting existing dimensions

What steps will reproduce the problem?
1. use default config with core filters insert_img_dimensions is enabled in the 
core filters

What is the expected output? What do you see instead?
added width and height for images when those attributes are missing.
instead width and height are added even when they already exist.

What version of the product are you using? On what operating system?
ubuntu 10.04.1 LTS 32bit

Please provide any additional information below.

wrong file name in the download page

I found that in the page 
http://code.google.com/intl/zh-CN/speed/page-speed/download.html all file names 
start with "mod_pagespeed", but the name of file to download starts with 
"mod-pagespeed", for example 
https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-beta_current_i386.rpm

So, all "mod_pagespeed" in the download page should be replaced with 
"mod-pagespeed" or the name of files to download should be replaced with 
"mod_pagespeed".

rewrite_css filter incompatible with CSS3 media queries

CSS3 media queries get destroyed with the rewrite_css filter using 0.9.0.0-128.

For instance, this CSS:

@media screen and (max-width: 290px), screen and (max-device-width: 290px) {
    .selector {
        display: none;
    }
    .otherselector {
        display: block;
    }
}


turns into this after passing through the rewrite_css filter:

@media screen,and,screen,and{.selector{display:none}}@media 
screen,and,screen,and{.otherselector{display:block}}


Instead, it should be written like this I believe:

@media screen and (max-width:290px),screen and 
(max-device-width:290px){.selector{display:none};.otherselector{display:block}}


These media queries are very important for developing pages that render nicely 
on a wide range of devices (e.g. phones), so I hope that this gets fixed soon! 
In the meantime, I have disabled the rewrite_css filter.

>> I'm sure some of these could be fixed with some tweaking to the
configuration, but I thought I'd still put these in case it can be
helpful to the developers working on the module.

> Are you saying that you requested an image and it gave you this error 
message? That's good to know. It means that it was parsing that image as an 
html doc! I believe we choose which files to rewrite based on MIME type 
reported by Apache, do you think there would be any reason that this would have 
been reported as text/html or anything like that?

Thanks for your explanation of the error messages. The images are
generated in PHP and are loaded using a url ending in .php, but I set
the content-type HTTP header to image/png, so it shouldn't be an
issue.
Here are the response headers for one of the images that resulted in
the above error:

Support for CSS @import

A feature request: Currently mod_pagespeed rewrites css that is pulled in with 
the <link> tag just fine, e.g.:

<link rel="stylesheet" type="text/css" 
href="http://www.mysite.com/mystylesheet.css" />

However, it could be nice it it would work with @import as well, e.g. 

<style type="text/css" media="screen">@import 
url(http://www.mysite.com/mystylesheet.css) ;</style>

We have a lot of sites that are using that pattern.

mod_pagespeed does not rewrite that in my end. If the current mod_pagespeed 
version is supposed to pick up @import I can provide some debug info.

Pagespeed version: 0.9.0.0-128

Need conf file directive to blacklist a subdirectory or wildcard syntax

When a site has large volumes of already-optimized images, it makes no sense to 
add cache and CPU pressure to attempt to optimize them further.

We should add conf file directive

  ModPagespeedExcludeDirectory [wildcarded_spec]

This directive should be able to appear multiple times.

Original issue reported on code.google.com by [email protected] on 8 Nov 2010 at 12:16

Add Example config files

We should add example configurations for various situations (single domain, 
multiple domains, conservative rewriter set, liberal set, ...)

This is running on the latest mod_pagespeed, under Centos 5.5 - apache 2.2.3, 
with Zend Engine v2.2 and eAccelerator installed.

I did originally have php_speedy also installed and in use, but found that 
mod_pagespeed was struggling to access php_speedy's own cached files.

How do we deal with non-standard ports?

Do we allow domain names to have port numbers? Do we restrict domain rewriting 
based on port?

Ex: is

ModPagespeedDomain www.example.com:81

allowed?

If we have

ModPagespeedDomain www.example.com

will we rewrite resources at http://www.example.com:81/...?

Internal Server Error - Not actually an error

We have seen this as well during testing. I'm pretty sure is not actually a 
server error, but a bad header serialization. We currently use the same class 
for both Request and Response headers, and so the status code is initialized to 
0 for Request headers and never changed or used (only printed). This should 
have no actual affect on your server, but we'll try to get this fixed anyway so 
it's not so disconcerting/confusing :)

mod_pagespeed does not handle application/xhtml+xml

I serve pages with the mime-type application/xhtml+xml (for xhtml 1.1). This 
should be optimized the same as html, but it does not work. xhtml can also be

when the server provides an Expires header, our cache extension may not work everywhere

In some configurations, Apache will add an Expires header to resources.

This can conflict with our cache extension headers, which use Cache-Control: 
max-age.

In most cases this is a non-issue since CC max-age is preferred to Expires per 
the HTTP/1.1 RFC.

However Firefox (through v4?) and HTTP/1.0 proxies will use Expires when both 
are present.

When an Expires header is present, we should overwrite it with a date that 
matches the value in the CC max-age header.

should not add 'public' to Cache-Control

We currently add 'public' to the Cache-Control header. This is unnecessary. See 
http://code.google.com/p/page-speed/issues/detail?id=9 for some background.

We should only add the max-age directive when extending cache lifetimes.

I ensured that I added a wildcard value for ModPagespeedDomain that will match 
the domain I am testing on.  I left the default CoreFilters.  By looking at the 
source as well as the mod_pagespeed_statistics, I can see that it does not 
appear to be doing any processing on files served from Passenger.

These are all internal sites, however I'm hoping someone else with Passenger 
can provide a better example.

Very slow memory leak

mod_pagespeed appears to have a very slow memory leak, even with "ModPagespeed
