Try adding REQUEST as a parameter to your method.

RE: [Zope] Image Upload detection

There may be an easier way, but here's how I'm doing it. In the DTML Method that is the target of the post, do something like this (untested):        This will determine the file size of the file and if non-zero, will add it to the current folder. The second seek might not be necessary (it depends on whether manage_addImage() or whatever you do with the file does it). PS: It's multipart _encoding_, not encryption. Basically the browser just base64 encodes the data and sends it as text. HTTP/MIME supports the "binary" content transfer encoding for a multipart value, which is roughly 12.5% more efficient compared to base64, although I have never checked whether modern browsers support this. -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin.

getting at vars from <form>'s in external methods

I'm sure this is obvious - but I can't find it anywhere. How can my external method get the value of a variable set from a <form> submit?

Image Upload detection
by Phil Grove 17 Jun '99

17 Jun '99

Hello all, second question of the day. Right, how do you detect if an image has been provided for upload when using the MULTIPART encryption method on a form? Basically, i have got a form that uploads three images to Zope and the user has the choice to upload between 1 and 3 pictures, so obviously, i need to check if the file boxes are empty or not. For example: <INPUT TYPE="file" NAME="newImg"> at the zope end:  image is here  nothing there matey boy  does not work.... any ideas on how to check??? Please help, i am losing my hair very quickily.... Cheers, P. --------------------------------------------------------------------- Phil Grove phil.grove(a)flg21.com Web Development 0113 2949494 flg21 http://www.flg21.com ---------------------------------------------------------------------

In that case, you can extend the external method to do it's own logging to a nice common format you can analyze externaly. In fact, you could even INSERT a record into an SQL database (this might be to heavy weight for you though). Note that I'll be thinking in the next couple of weeks about a 'virtual' like built in method to do outgoing HTTP GETs on URLs, this will probably not be seen until 2.0 if at all. > Is PCGI mutually exclusive with mod_perl?

So, Zope can at least hose a 10 Mb Ethernet (Note, a 70MB FTP between the two machines yielded 800 KB/s, I think the amount of request/response and tcp connect/disconnect overhead could account for the other 144 KB/s, at least to a 10% margin of error). When Rob buys me a 100MB card for my other machine, I'll rerun the benchmark to see if Zope can beat the 10Mb limit. Also not that the ~37 requests per second I got (this is the average between all benchmarks) equates to approx *3.2 million hits per day* on one moderately fast PII with no fancy hardware. > Otoh, if transfers really were fast (that is, faster than > 10-11KB/sec), > and the time taken to complete a request was low, the transfer time > should explode exponentially.

Note that load average and % of time spent in the CPU are not the same thing. The load average hit 1.5 but that just means the machine was busy, not swamped. To test a a vague theory here, I fired up X, Netscape, vmware (which is a massive CPU hog) and a bunch of shells and XEmacs, and ran a 10000 request benchmark. The machine ran smoothly, vmware didn't stutter or pause, X switched quickly between virtual screens, and XEmacs didn't even appear to feel it. Meanwhile Zope happily pushed 538 Kb/s out the ether card. > > I'm planning on putting together a simple httplib-built benchmark test > just to get some raw numbers, although I'd like to try putting the > timing logic inside Zope. > We would be interested in seeing what you come up with (code and numbers). -Michel

I'm not familiar enough to Linux to say this for sure, but my guess is that it _would_ be using a high-resolution system timer. Otoh, if transfers really were fast (that is, faster than 10-11KB/sec), and the time taken to complete a request was low, the transfer time should explode exponentially. (Eg., 10K transferred in 10ms should yield a transfer rate 1MB/sec.) I'd be very interested to hear about what the CPU load was during the test run. If it's anything above 5-8% (average), that's not promising at all. The fact that adding more concurrent sessions did not regrade performance seems to indicate that CPU load was not too bad. I'm planning on putting together a simple httplib-built benchmark test just to get some raw numbers, although I'd like to try putting the timing logic inside Zope. >> Yep, but ASP, PHP, Cold Fusion, etc. have proven to be very, >> very fast. >> > >I can see PHP being convincingly 'proven' to be fast, but I have doubts >about the validity *any* comercial company says about their closed >source program.
