[jira] Created: (WAGON-264) compressed tarball download problems
compressed tarball download problems
------------------------------------
Key: WAGON-264
URL: http://jira.codehaus.org/browse/WAGON-264
Project: Maven Wagon
Issue Type: Bug
Components: wagon-http-lightweight
Affects Versions: 1.0-beta-5, 1.0-beta-4, 1.0-beta-3, 1.0-beta-2
Reporter: Lee Thompson
HTTP wagon will uncompress tarballs it downloads, sometimes badly. Downloading openssl results in an unpressed download
$ mvn -X wagon:download-single -Dwagon.fromFile=openssl-0.9.8k.tar.gz -Dwagon.url=http://www.openssl.org/source -Dwagon.toDir=./
$ tar tzf openssl-0.9.8k.tar.gz
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error exit delayed from previous errors
$ tar tf openssl-0.9.8k.tar.gz | more
openssl-0.9.8k/apps/
openssl-0.9.8k/apps/app_rand.c
Downloading expat results in a corrupted file
mvn -X wagon:download-single -Dwagon.fromFile=expat-1.98.8.tar.gz -Dwagon.url=http://prdownloads.sourceforge.net/expat -Dwagon.toDir=./
$ tar tf expat-1.98.8.tar.gz
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Read 1943 bytes from expat-1.98.8.tar.gz
tar: Error exit delayed from previous errors

John Casey commented on WAGON-264:
----------------------------------
The wagon-maven-plugin will have to adjust (and be re-released) to handle httpConfiguration, I would expect. That is, unless it deals with the WagonManager component from maven-artifact-manager, which in turn handles Wagon instances that are configured using <server> entries in the settings.xml...which IMO is probably a good practice for it to do...

[jira] Issue Comment Edited: (WAGON-264) compressed tarball
download problems
Posted by "John Casey (JIRA)" <ji...@codehaus.org>.

John Casey edited comment on WAGON-264 at 6/25/09 12:09 PM:
------------------------------------------------------------
The following headers are set by default in the latest trunk revisions of the httpclient-driven wagon (this is the http wagon that will be used in Maven 2.2.0):
{code}
method.addRequestHeader( "Cache-control", "no-cache" );
method.addRequestHeader( "Cache-store", "no-store" );
method.addRequestHeader( "Pragma", "no-cache" );
method.addRequestHeader( "Expires", "0" );
method.addRequestHeader( "Accept-Encoding", "gzip" );
{code}
To disable the Accept-Encoding header, you will have to disable all of these default headers, then re-add the ones you want to keep. As of the versions checked into trunk, you can do this by editing the settings.xml, like this:
{code:xml}
<server>
<id>myrepo</id>
<configuration>
<httpConfiguration>
<all>
<useDefaultHeaders>false</useDefaultHeaders>
<headers>
<header>
<name>Cache-control</name>
<value>no-cache</value>
</header>
<header>
<name>Cache-store</name>
<value>no-store</value>
</header>
<header>
<name>Pragma</name>
<value>no-cache</value>
</header>
<header>
<name>Expires</name>
<value>0</value>
</header>
</headers>
</all>
</httpConfiguration>
</configuration>
</server>
{code}
Note that the above configuration will work for wagons accessed through the WagonManager in maven-artifact-manager. If you're managing Wagon instances elsewhere, you may need to provide access to the new HttpConfiguration and HttpMethodConfiguration config classes in wagon-http-shared.

Lee Thompson commented on WAGON-264:
------------------------------------
I'm reading rfc2616 and indeed, I agree with you that the openssl webserver is misconfigured deviating from HTTP spec. The webserver in this case transmitted Content-Type of gzip with no Content-Encoding but declared in the reply Content-Encoding of gzip. Unfortunately, it looks to me like the openssl config is following the Apache documentation to the letter....
http://httpd.apache.org/docs/2.2/mod/mod_mime.html#addencoding
specifically --> To make this long story short, you should always use x-gzip and x-compress for these two specific encodings.
The Apache docs are probably incorrect (or confusing at best) leading to this issue. I'd have to go back to the point that wget, and curl (and I just tested firefox) will all download from these sites and get the correct file. I'd also go back to my point that performance is worse when you ask for GZIP encoding for filetypes that are already compressed. The only typical maven uncompressed file types are the pom XML files and the SHA1 and MD5SUM hash files and these artifacts are so small that the benefit is negligible. While wagon might not have a bug in regards to rfc2616, it does have an issue dealing with sites who read the Apache configuration documentation. Wagon is the only http client I know of that can't download tarballs from sourceforge and openssl. (Lots of sourceforge mirrors have this config problem). The internet is a cooperative media and strict compliance is often compromised when interoperability concerns are brought in.
Please make wagon defend itself from badly configured webservers.

------------------------------------
Looks like the client can not see the bypass behavior of mod_gzip. If you run this little groovy program, it will dump the request headers...
URL url = new URL ( "http://prdownloads.sourceforge.net/expat/expat-1.98.8.tar.gz" );
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestProperty( "Accept-Encoding", "gzip" );
int responseCode = urlConnection.getResponseCode();
println "Response code is " + responseCode
Map<String, List<String>> hdrFields = urlConnection.getHeaderFields()
println hdrFields
output...
Response code is 200

Suggest a "getCompressedFileExtension()" method to Resource.java which checks the file extenstion for common internet compressed file types like jar, zip, gz, tgz, bz2 and if getCompressedFileExtension() is true, don't as for the gzip encoding and don't check for it either. This check would be needed fro http and https.

----------------------------------
This looks like a configuration issue on the openssl.org website. The first, openssl, is using content-encoding 'x-gzip' and appears not to actually be re-compressing the file, while the other two websites use no content-encoding. I'm guessing they messed up something similar to this:
{noformat}
AddType x-gzip .gz
{noformat}
Here's the output from hitting three different servers with curl:

[jira] Commented: (WAGON-264) compressed tarball download problems
Posted by "Lee Thompson (JIRA)" <ji...@codehaus.org>.

Lee Thompson commented on WAGON-264:
------------------------------------
I believe the problem is the wagon-http-lightweight is ignoring the DECLINED:FEXT_GZ status code returned by mod_gzip. When this error code is seen, mod_gzip passed on dynamic compresson since the request is for an already compressed gzip file.
Wagon requesting mod_gzip on ZIP and JAR files doesn't seem to trigger this behavior. It would be an optimization to not ask for compression on JAR and ZIP files as these files are compressed but mod_gzip doesn't seem to know that. Double compressing consumes time on both the client and server with no decrease in download payload (download sometimes increases somewhat)

[jira] Closed: (WAGON-264) compressed tarball download problems
Posted by "John Casey (JIRA)" <ji...@codehaus.org>.
[ http://jira.codehaus.org/browse/WAGON-264?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
John Casey closed WAGON-264.
----------------------------
Resolution: Fixed
The following headers are set by default in the latest trunk revisions of the httpclient-driven wagon (this is the http wagon that will be used in Maven 2.2.0):
{code}
method.addRequestHeader( "Cache-control", "no-cache" );
method.addRequestHeader( "Cache-store", "no-store" );
method.addRequestHeader( "Pragma", "no-cache" );
method.addRequestHeader( "Expires", "0" );
method.addRequestHeader( "Accept-Encoding", "gzip" );
{code}
To disable the Accept-Encoding header, you will have to disable all of these default headers, then re-add the ones you want to keep. As of the versions checked into trunk, you can do this by editing the settings.xml, like this:
{code:xml}
<server>
<id>myrepo</id>
<configuration>
<httpConfiguration>
<all>
<useDefaultHeaders>false</useDefaultHeaders>
<headers>
<Cache-control>no-cache</Cache-control>
<Cache-store>no-store</Cache-store>
<Pragma>no-cache</Pragma>
<Expires>0</Expires>
</headers>
</all>
</httpConfiguration>
</configuration>
</server>
{code}
Note that the above configuration will work for wagons accessed through the WagonManager in maven-artifact-manager. If you're managing Wagon instances elsewhere, you may need to provide access to the new HttpConfiguration and HttpMethodConfiguration config classes in wagon-http-shared.

------------------------------------------------------------
Looks like the client can not see the bypass behavior of mod_gzip. If you run this little groovy program, it will dump the request headers...
URL url = new URL ( "http://prdownloads.sourceforge.net/expat/expat-1.98.8.tar.gz" );
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestProperty( "Accept-Encoding", "gzip" );
int responseCode = urlConnection.getResponseCode();
println "Response code is " + responseCode
Map<String, List<String>> hdrFields = urlConnection.getHeaderFields()
println hdrFields
output...
Response code is 200

Suggest a "getCompressedFileExtension()" method to Resource.java which checks the file extenstion for common internet compressed file types like jar, zip, gz, tgz, bz2, mp3, etc. If getCompressedFileExtension() is true, don't ask for the gzip encoding and don't check for it either. This check would be needed for http and https.
