Bug fix and new features.
The source is in http://plan9.aichi-u.ac.jp/netlib/

This page describes only the new feature. Basic features are unchanged. Look Pegasus 2.2 documents for more detail.

More directories in $web

What was the problem?

Let's $web be httpd root for Pegasus.
We had restriction that only three directories "bin", "etc" and "doc" can be added in $web. Now the restriction has been removed.

Pegasus 2.3 internally executes (in rc notation)
bind -a $web /usr/web

Example

Now we can locate a private files such as users information for a web service as following

	$web/users

then the file "users" is outside of document root, and therefore only accessible via CGI.

CGI timeout for each CGI

What was the problem?

Some CGIs take much time to complete the task. The time is CGI dependent.
Therefore I enabled dynamical resetting of CGI timeout for each CGI.

A environment variable "hpid" is introduced for this purpose.
The "pid" is that of Pegasus in service.

Example 1

In starting service, execute

	echo -n timeout 180 > /proc/$hpid/note

which will reset CGI timeout to 180 seconds.

Example 2

The example below written in Python is extracted from a script on my server.

def settimeout(n):
        note="/proc/%d/note"%hpid
        f=open(note, "w")
        if f==None:
                print "unable to open %s"%note
                print "timeout is not set"
                return
        f.write("timeout %d"%n)
        f.close()
e=os.environ
hpid=0
if e.has_key("hpid"):
        hpid=int(e["hpid"])
if hpid:
        settimeout(180)
# continues heavy loaded tasks

New option for hfmt

New option "-x" is added to a CGI tool "hfmt" so that non-ascii runes in path name can be converted to %HH format.

What was the problem?

Microsoft IE sometimes fails to handle UTF-8 encoded path name in href value.

Example

The following code in rit scrit will produce local references to all files in the current directory.

<pre>${ ls | hfmt -x '<a href="%U">%H</a>' 1 1}</pre>
