I also find OneShot.cgi to be too slow for testing, perhaps because I have a
relatively slow machine. In any case, I modified WebKit.cgi (which is run on
every request) to first look for changes in my source tree, and
restart the appserver if there were any changes made. That way I have a delay
on the first request after making a change, but for subsequent pages it's
almost as fast as WebKit.
I had to allow the www-data user (under which cgi runs on my machine) write
permissions to my app directory, so that it can create a timestamp and write
to the log file.
Here's the source, hope it's useful:
#!/usr/bin/env python
# If the Webware installation is located somewhere else,
# then set the WebwareDir variable to point to it.
# For example, WebwareDir = '/Servers/Webware'
WebwareDir = '/home/jdhildeb/projects/Webware'
# If you used the MakeAppWorkDir.py script to make a separate
# application working directory, specify it here.
AppWorkDir = '/home/jdhildeb/projects/mobile/app'
try:
import os, sys
# mod starts here
file = os.popen("cd %s ; find . -name '*.py' -newer timestamp" % ( AppWorkDir
) , "r" )
output = file.readlines()
file.close()
if len(output) > 0:
os.system("cd %s; kill `cat appserverpid.txt` ; touch timestamp; sleep
1 ; ./AppServer &>appserver.log &" % AppWorkDir )
# mod ends here
if WebwareDir:
sys.path.insert(1, WebwareDir)
else:
WebwareDir = os.path.dirname(os.getcwd())
webKitDir = os.path.join(WebwareDir, 'WebKit')
if AppWorkDir is None:
AppWorkDir = webKitDir
else:
sys.path.insert(1, AppWorkDir)
import WebKit.CGIAdapter
WebKit.CGIAdapter.main(AppWorkDir)
except:
import string, sys, traceback
from time import asctime, localtime, time
sys.stderr.write('[%s] [error] WebKit: Error in adapter\n' %
asctime(localtime(time())))
sys.stderr.write('Error while executing script\n')
traceback.print_exc(file=sys.stderr)
output = apply(traceback.format_exception, sys.exc_info())
output = string.join(output, '')
output = string.replace(output, '&', '&')
output = string.replace(output, '<', '<')
output = string.replace(output, '>', '>')
output = string.replace(output, '"', '"')
sys.stdout.write('''Content-type: text/html
<html><body>
<p>ERROR
<p><pre>%s</pre>
</body></html>\n''' % output)
