[Zope-dev] Redirecting from the manage interfaces.
Hi.
I've been browsing through the Zope and Zope-dev archives without finding
anything related to this, please stop me if it has already been dealt
with. :)
technical person = someone who doesn't mind fuzzing around with the
manage_main pages
non-technical person = someone who needs everything in bright nice colors
and would start crying if they saw the manage_main
page, or anything similar.
I have a Product that allows a customer of mine to add some nice pictures
(Image object) to a folder. The add-method is nice and doesn't display
any horrible technical information. I wasn't very keen on making a
add-method for both the technical person and the non-technical person, so
I hacked the source code a bit. I changed the the lib/python/OFS/Image.py
It used to look like this:
"""
def manage_addImage(self, id, file, title='', precondition='',
content_type='', REQUEST=None):
[...]
if REQUEST is not None:
try:url=self.DestinationURL()
except: url=REQUEST['URL1']
REQUEST.RESPONSE.redirect('%s/manage_main' % url)
return id
"""
Which I changed into:
"""
def manage_addImage(self, id, file, title='', precondition='',
content_type='', REQUEST=None, redir=None):
[...]
if redir is not None:
REQUEST.RESPONSE.redirect('%s' % redir)
elif REQUEST is not None:
try:url=self.DestinationURL()
except: url=REQUEST['URL1']
REQUEST.RESPONSE.redirect('%s/manage_main' % url)
"""
Now I can redirect the victim... erm.. customer to the method I want to,
and they are pleased that they don't have to see the management interface.
This saves me a lot of time, since I don't have to make several
add-methods, and maintainace is a more joyable happening. :)
This 'redir' thing is something I've stuck into a lot of .py files
(for example, I use it in the manage_delObjects and others). And
it is something I do every time a new Zope release comes out. Could this
be to any use for anybody besides me? And if it could, how about adding
it to the next release?

But I have to pass something with the REQUEST, or else it won't add the image, right? A convention I've seen that works just a little better is to redirect based on the existence of a RESPONSE object. You need RESPONSE to redirect, so if it isn't provided, you shouldn't redirect. Of course this needs to be documented and more reliable.

snip dicussion about large tables I take that back in the previous mail to Steve about the large table. We have one and I split the header from the rest as you suggested. But since it is not streaming the information, it will still pop up all at once. Any ideas? Steve just send me a file and a method but I do not understand what to get from it. I am checking the iste, whether I call RESPONSE.XXX somewhere in the middle of the page.

snip Method doc string
Looks like it's more that just a tweak, though :-(
So, how can I use this method? I do not understand the internals of the
ZServer completely.
You've got a RESPONSE object. For HTTP stuff, it will be a HTTPResponse
as defined in lib/python/ZPublisher/HTTPResponse.py.
You can use the write(self, data) method of this response object to
stream data directly to your client, independent (to a degree) of Zope's
transaction processing.
This is the method from HTTPResponse.
def write(self,data):
"""\
Return data as a stream
HTML data may be returned using a stream-oriented interface.
This allows the browser to display partial results while
computation of a response to proceed.
The published object should first set any output headers or
cookies on the response object.
Note that published objects must not generate any errors
after beginning stream-oriented output.
"""
if not self._wrote:
self.outputBody()
self._wrote=1
self.stdout.flush()
self.stdout.write(data)
So, you could set output headers and cookies as needed, then, before the
rest of the processing on your page, have a dtml-call
"RESPONSE.write('the top of the page')".
Then again, I've never tried this. YMMV and all that.

Re: [Zope-dev] Optimization and speed
It looks like the pages you are serving are mostly big tables. Both Netscape and IE won't reder anything unless they got everything in the table. I would try to time the 'wget' speed to verify if zope is slow or not. Well, I kinda did that using telnet. I telneted into port 80 and then asked for an HTML page. I took about 3 secs (that's okay) for Zope to render the HTML page and then it bursted it out all at once. As I read from the other E-mails, Zope does not stream HTML to the HTTP Server till it is done laying out the site. That is the real problem. But the problem is still not solved. I am still 50% slower than other sites, even though Zope does not stream the data out. I played with the SQL Method cache; maybe I have to increase it more.

[Zope-dev] Optimization and speed
Hello everyone, I write this mail, because I could not find anything useful in the archives: I have a pretty big site with quiet a big database (PostGreSQL) in the background. When a site loads I can tell that after about 5 seconds the site is ready to download. The site downloads quickly thereafter if I am on a T1, DSL or Cable Modem connection. But since most of our users have 28.8k and 56k modem connection, we have to optimize for them too. When accessing the site over a modem, it takes a long time to load the site and then it pops up all at once (in IE (AOL) and Netscape). Is there a way that I can send parts of the HTML as it is generated, so that the customer starts seeing information before the entire site is loaded. Our site is about 50% slower than our competitors sites (we are serving 62kB and the competitor has up to 203kB and is 50% faster!!!) which use PHP and ColdFusion. I know that Zope is not slower. I strongly believe it is the HTML output which is not optimized (we are going to speed up the DB connection very soon by dedicating a NIC only for the DB communication). Technical Facts: - Zope 2.1.6+PCGI+Apache - Virtual Hosts for HTTP and HTTPS - PostGreSQL 7.0 (DB size: 50MB), ZPyGreSQLDA, UserDB - ZODB threads: 4 - Web Server: Pentium 500, RH 6.1, 322MB RAM (not all used), 100 MBit NIC - DB Server: Pentium 500, RH 6.1, 322MB RAM (plenty left to use), 100 MBit NIC - dedicated subnet If someone could give me some tips where I should start looking for speed holes, please let me know. Do you think it is the DB which could be so slow and I should cache search results more, are there ZServer/Apache options I can set or anything else in Zope I should have a look at?

Hi Stephan, This sounds like more of a HTML problem than a Zope problem, especially since the fast links have no trouble with the server. Zope obviously is fast enough to serve them. I bet your site heavily uses tables and images This will cause the browser to not display anything until it knows how to lay out the table. If your whole page is contained in one table, this means that your page won't pop up until the browser has seen the table end tag and knows the sizes of all images. You can help the browser a bit by making sure all IMG tags have a width and height attribute so the browser won't have to wait for the images to start to load. IIRC, Internet Explorer will even show the table without that information, and reflow the table if needed. It still will wait until it has the whole table. Only Mozilla reflows all incoming HTML on the fly, even before the end of the table is seen. When they the optimisations come in for Netscape 6 preview 3, it'll beat the hell out of Internet Explorer with this. So, if you want to make sure that your clients see something before all HTML is in, split up the table into a header and the rest, if possible. Then the browser has something to show while loading the rest of the page. This is what sites like www.cnet.com do; they show you a banner while waiting. -- Martijn Pieters | Software Engineermailto:[EMAIL PROTECTED] | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ | ZopeStudio: http://www.zope.org/Products/ZopeStudio - ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope] Optimization and speed
Hello everyone, I write this mail, because I could not find anything useful in the archives: I have a pretty big site with quiet a big database (PostGreSQL) in the background. When a site loads I can tell that after about 5 seconds the site is ready to download. The site downloads quickly thereafter if I am on a T1, DSL or Cable Modem connection. But since most of our users have 28.8k and 56k modem connection, we have to optimize for them too. When accessing the site over a modem, it takes a long time to load the site and then it pops up all at once (in IE (AOL) and Netscape). Is there a way that I can send parts of the HTML as it is generated, so that the customer starts seeing information before the entire site is loaded. Our site is about 50% slower than our competitors sites (we are serving 62kB and the competitor has up to 203kB and is 50% faster!!!) which use PHP and ColdFusion. I know that Zope is not slower. I strongly believe it is the HTML output which is not optimized (we are going to speed up the DB connection very soon by dedicating a NIC only for the DB communication). Technical Facts: - Zope 2.1.6+PCGI+Apache - Virtual Hosts for HTTP and HTTPS - PostGreSQL 7.0 (DB size: 50MB), ZPyGreSQLDA, UserDB - ZODB threads: 4 - Web Server: Pentium 500, RH 6.1, 322MB RAM (not all used), 100 MBit NIC - DB Server: Pentium 500, RH 6.1, 322MB RAM (plenty left to use), 100 MBit NIC - dedicated subnet If someone could give me some tips where I should start looking for speed holes, please let me know. Do you think it is the DB which could be so slow and I should cache search results more, are there ZServer/Apache options I can set or anything else in Zope I should have a look at?

Hi Stephan, This sounds like more of a HTML problem than a Zope problem, especially since the fast links have no trouble with the server. Zope obviously is fast enough to serve them. I bet your site heavily uses tables and images This will cause the browser to not display anything until it knows how to lay out the table. If your whole page is contained in one table, this means that your page won't pop up until the browser has seen the table end tag and knows the sizes of all images. You can help the browser a bit by making sure all IMG tags have a width and height attribute so the browser won't have to wait for the images to start to load. IIRC, Internet Explorer will even show the table without that information, and reflow the table if needed. It still will wait until it has the whole table. Only Mozilla reflows all incoming HTML on the fly, even before the end of the table is seen. When they the optimisations come in for Netscape 6 preview 3, it'll beat the hell out of Internet Explorer with this. So, if you want to make sure that your clients see something before all HTML is in, split up the table into a header and the rest, if possible. Then the browser has something to show while loading the rest of the page. This is what sites like www.cnet.com do; they show you a banner while waiting. -- Martijn Pieters | Software Engineermailto:[EMAIL PROTECTED] | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ | ZopeStudio: http://www.zope.org/Products/ZopeStudio - ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
