Jim,

This happened on Fedora 18 from Chen Xu at Brandeis. I don't know the details.

Jim and Anchi,

Here is the screen output.

[xuchen@localhost ~]$ redux --filename=images.jpg --oformat=PNG > images.png
no wisdom found
NOT IN MEMORY: Format(30988112,oformat=PNG,rgb=False)
IN FILE: Format(30988112,oformat=PNG,rgb=False)

There are two lines
"*** Using custom copy of fftw3 wrapper
PNG"

which are not in the stderr but somehow written into image.

I am using Fedora18 64-bit. Let me know how I can give more info about this.

-Chen

to summarize from the recent email trail:

The text added to the PNG is due to the older version of calc_fftw3.py which printed this message to stdout. In the more recent revision, the messages are directed to stderr. The solution is to merge the recent changes into the branch.

The next problem encountered is that the php redux client code will not connect to the redux server.

Chen,

Can you look in /var/log/httpd/error_log to see if any errors are generated when you try to view an image.
A similar problem recently was due to the socket extension for php not being installed.

If there is nothing useful in the log, the first thing to check is how the redux server and/or client is configured with a host name and port number. Make sure it is what you expect.

Check the client side configuration (php). The redux server host and port number are configured in your myamiweb/config.php:

define('SERVER_HOST', "localhost");
define('SERVER_PORT', "55123");

reduxd is configured by the redux.cfg file. You can check the content of that config file, and also verify that this config file will be read properly by starting python and entering these commands:

>>>  import redux.reduxconfig
>>>  redux.reduxconfig.config
{'log file': 'redux.log', 'server host': 'localhost', 'server port': 55123, 'cache on': False}

Now test reduxd. Start reduxd in one terminal, then from another terminal make a simple connection to it using telnet:

telnet localhost 55123

If the telnet test is already working with your original config, then the problem is in the php client side, and you would expect to see some errors in your web log. In that case, you may have to try some different configurations of host name in config.php. Instead of localhost, you could try "127.0.0.1" or the IP number of the host as seen from your local network.

Please post your results here and we will continue to solve this.

Jim

Chen,

I merged all the recent redux and pyami/fft changes in trunk to 2.2-redux branch. It should fix the printing problem this issue is originally for. Please update. This way we know we are all working on the same version. The recent changes have more places catching odd configurations and correct them. It might help in this situation.

Anchi

Dear Jim and Anchi,

thanks your help!!!

Here is what I found:

1) from /var/log/httpd/error_log, it generates lines including
[Thu Jul 11 17:26:08.308653 2013] [:error] [pid 7068] [client ::1:35554] PHP Warning: socket_connect(): unable to connect [13]: Permission denied in /var/www/html/myamiweb/inc/redux.inc on line 357, referer: http://localhost/myamiweb/viewerxml.php

2)from /var/www/http/myamiweb/config.php

define('SERVER_HOST',"localhost");
define('SERVER_PORT',"55123");
[root@localhost ~]# python
Python 2.7.3 (default, Aug 9 2012, 17:23:57)
[GCC 4.7.1 20120720 (Red Hat 4.7.1-5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import redux.reduxconfig
redux.reduxconfig.config

{'server host': 'localhost', 'server port': 55123, 'cache on': True, 'log file': '/tmp/redux.log', 'cache path': '/var/cache/myami/redux', 'cache mem size': 500, 'cache disk size': 500}

3) while reduxd is started from one terminal, from other terminal
[xuchen@localhost log]$ telnet localhost 55123
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

-Chen

It looks like telnet was successful on the second attempt when it used the local IP number directly: 127.0.0.1. The first attempt was trying "::1" (IPV6, maybe?)

This could mean the the php client is also trying "::1" and failing. You can try to configure your myamiweb/config.php to set the redux host name to 127.0.0.1 directly and maybe that will work.

Let us know.
Jim

Hi Jim,

change the line to use 127.0.0.1 in config.php

//define('SERVER_HOST',"localhost");
define('SERVER_HOST',"127.0.0.1");
define('SERVER_PORT',"55123");

and fired up reduxd from on terminal, while the telnet went through
[xuchen@localhost log]$ telnet 127.0.0.1 55123
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

However, the MRC still doesn't display, after restart httpd.

-Chen

Chen, is there anything new in /var/log/httpd/error_log?
Or the same error message as before?

Jim,

1) if I start reduxd via service, telnet doesn't connect at all, including 127.0.0.1

2) Here are some line from error_log, I tried both localhost/myamiweb and 127.0.0.1/myamiweb,
still socket communication permission issue?

===================

Hi Jim and Anchi,

I got the same error_log line for httpd, even without reduxd started at all.

-Chen

Hi, Chen,

Please run reduxd directly, don't use service until we get the simpler case working.

I also just found that the viewerxml.php in myami-2.2-redux does not work even here.
Go to troubleshooting page to see if you get those images displayed.

Anchi

Hi Anchi,

troubleshooting page never displays the two images. I am kind of glad
you also have this issue, in the sense you can debug it easier there.

-Chen

Sorry to get your hope up. It was my problem. I was switching versions of myami and the browser still remembers the javascript of the trunk version so that it didn't match the php instruction (2.2-redux) with the loaded javascript (trunk). Once I restarted the web browser, it worked.

Try if this help. It came up from google search
