Why SQLSession 0.3.0 sometimes gets stuck
by Shai Berger 29 Jul '01

29 Jul '01

Dear Anthony and Zopers, At Aristocart, we had been using SQLSession until a few months ago, for our e-commerce web application. We kept having problems where those sessions would get stuck, and sometimes cause the whole Zope instance to become hosed. After a few weeks of fiddling with the details of the SQL Methods (in part to add expiration to the sessions), we dispared and moved to CoreSessionTracking. CST 0.8 solved our hangs, crashes and stickiness problems. But we still needed a SQL-based sessioning mechanism, because this was standing between us and eliminating Zope's single-point-of-failure problem (as we keep all the application data in the relational database, if we could just move the sessions there too, we could have multiple Zope servers with read-only identical ZODBs). I ended up solving the problem by developing special product for keeping CST sessions on an Oracle database, SqlSDC. However, in the last phases of the struggle to make it work, I found out what was the problem with SQLSession. It is easy enough to fix, but I don't have the time to do it myself. The problem is, essentially, with the order of commits. SQLSession assumes that commiting is done in the order of registration, and the documentation even mentions a patch to Transaction.py to make its registration look like it happened earlier -- to ensure it is committed before the relevant database connection. This is a sensible assumption, and is almost correct, but not correct enough. When a Zope transaction includes other transactions -- like a relational database transaction -- it uses two phase commit. This means that there are two rounds of messages: The first, "tpc_begin", says essentially, "prepare to commit"; the second, "tpc_finish", says "commit". Most database adapters, and other naive descendents of ZRDB.TM (including SQLSession 0.3.0), ignore the first, and call their _finish() method when they receive the second. However, while tpc_begin messages are sent according to the order of registration, the transaction mechanism uses the loop going over registered objects to put those objects in a dictionary, and the tpc_finish calls are done by looping on the values of this dictionary. Effectively, this means the tpc_finish messages are sent in _random_ order. From the transaction's point of view, this does not make awful nonsense: They have all been warned, and second-phase commits should be trivial operations that never fail -- like a commit on a database, or a flush on a file. If you think about it a bit longer, the first phase of a two-phase-commit is the most natural place for actions such as running update and insert SQL commands for keeping saving sessions into a database. It is a sort of preparation, to be finalized by the database commit. The solution, therefore, is simple: Modify SQLSession by overriding TM's tpc_begin, tpc_abort and tpc_finish so that the _finish method is called from tpc_begin, and tpc_finish does nothing. I do not remember the SQLSession source details so well, but if the registered object is in the ZODB, this will lead to a conflict error; to bypass this, you need a separate object to handle registration. To see a way of doing this, you are invited to look at the source of my SessionDataContainerBase. Both above-mentioned products are available from http://www.zope.org/Members/shai. Have fun, Shai.

I floated this very idea a few weeks ago, so I'm glad to see someone having a go at it. Eventually a mechanism will be needed to associate file extensions with metatypes; a couple of options spring to mind: each Product could be expected to specify its extension as it does for its icon and metatype; or else there could be a extension-mapper product that allowed for TTW configuration.

PIL, StringIO, manage_delObject and thumbnails
by Tom Cameron 29 Jul '01

29 Jul '01

I have been trying for several days now to create thumbnails in Zope. I ended up looking at the example code at: http://www.zope.org/Members/michel/ZB/ScriptingZope.html I am not sure how current this document is, but I tried to use the thumbnail script with no success. After many frustrating hours I found the following changes worked: def makeThumbnail(self, original_id, size=128): """ Makes a thumbnail image given an image Id when called on a Zope folder. The thumbnail is a Zope image object that is a small JPG representation of the original image. The thumbnail has a 'original_id' property set to the id of the full size image object. """ from PIL import Image -- from cStringIO import StringIO ++ from StringIO import StringIO <=I cant seem to get cStringIO to work import os.path # create a thumbnail image file original_image=getattr(self, original_id) -- original_file=StringIO(original_image.data) ++ original_file=StringIO(str(original_image.data)) <=needed to ensure string image=Image.open(original_file) image=image.convert('RGB') image.thumbnail((size,size)) thumbnail_file=StringIO() image.save(thumbnail_file, "JPEG") thumbnail_file.seek(0) # create an id for the thumbnail path, ext=os.path.splitext(original_id) thumbnail_id=path + '.thumb.jpg' # if there's and old thumbnail, delete it if thumbnail_id in self.objectIds(): -- self.manage_delObject(thumbnail_id) <= this does not work ++ self.manage_delObjects([thumbnail_id]) # create the Zope image object self.manage_addProduct['OFSP'].manage_addImage(thumbnail_id, thumbnail_file, 'thumbnail image') thumbnail_image=getattr(self, thumbnail_id) # set the 'originial_id' property thumbnail_image.manage_addProperty('original_id', original_id, 'string') I have no idea if these are errors or if things have changed. I am using Zope 2.3.2 and Python 1.5.2 on FreeBSD 4.0. I just thought I should report what I have found and hopefully save someone else the pain Tom

by quickcash＠eudoramail.com 28 Jul '01

28 Jul '01

Dear Friends & Future Millionaire: AS SEEN ON NATIONAL TV: Making over half million dollars every 4 to 5 months from your home for an investment of only $25 U.S. Dollars expense one time THANK'S TO THE COMPUTER AGE AND THE INTERNET ! ================================================== BE A MILLIONAIRE LIKE OTHERS WITHIN A YEAR!!! Before you say ''Bull'', please read the following. This is the letter you have been hearing about on the news lately. Due to the popularity of this letter on the Internet, a national weekly news program recently devoted an entire show to the investigation of this program described below, to see if it really can make people money. The show also investigated whether or not the program was legal. Their findings proved once and for all that there are ''absolutely NO Laws prohibiting the participation in the program and if people can - follow the simple instructions, they are bound to make some mega bucks with only $25 out of pocket cost''. DUE TO THE RECENT INCREASE OF POPULARITY & RESPECT THIS PROGRAM HAS ATTAINED, IT IS CURRENTLY WORKING BETTER THAN EVER. This is what one had to say: ''Thanks to this profitable opportunity. I was approached many times before but each time I passed on it. I am so glad I finally joined just to see what one could expect in return for the minimal effort and money required. To my astonishment, I received total $ 610,470.00 in 21 weeks, with money still coming in." Pam Hedland, Fort Lee, New Jersey. =================================================== Here is another testimonial: "This program has been around for a long time but I never believed in it. But one day when I received this again in the mail I decided to gamble my $25 on it. I followed the simple instructions and walaa ..... 3 weeks later the money started to come in. First month I only made $240.00 but the next 2 months after that I made a total of $290,000.00. So far, in the past 8 months by re-entering the program, I have made over $710,000.00 and I am doing it again. The key to success in this program is to follow the simple steps and NOT change anything.'' More testimonials later but first, ===== PRINT THIS NOW FOR YOUR FUTURE REFERENCE ====== $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ If you would like to make at least $500,000 every 4 to 5 months easily and comfortably, please read the following...THEN READ IT AGAIN and AGAIN!!! $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ FOLLOW THE SIMPLE INSTRUCTION BELOW AND YOUR FINANCIAL DREAMS WILL COME TRUE, GUARANTEED! INSTRUCTIONS: =====Order all 5 reports shown on the list below ===== For each report, send $5 CASH, THE NAME & NUMBER OF THE REPORT YOU ARE ORDERING and YOUR E-MAIL ADDRESS to the person whose name appears ON THAT LIST next to the report. MAKE SURE YOUR RETURN ADDRESS IS ON YOUR ENVELOPE TOP LEFT CORNER in case of any mail problems. === When you place your order, make sure you order each of the 5 reports. You will need all 5 reports so that you can save them on your computer and resell them. YOUR TOTAL COST $5 X 5=$25.00. Within a few days you will receive, vie e-mail, each of the 5 reports from these 5 different individuals. Save them on your computer so they will be accessible for you to send to the 1,000's of people who will order them from you. Also make a floppy of these reports and keep it on your desk in case something happen to your computer. IMPORTANT - DO NOT alter the names of the people who are listed next to each report, or their sequence on the list, in any way other than what is instructed below in step '' 1 through 6 '' or you will loose out on majority of your profits. Once you understand the way this works, you will also see how it does not work if you change it. Remember, this method has been tested, and if you alter, it will NOT work !!! People have tried to put their friends/relatives names on all five thinking they could get all the money. But it does not work this way. Believe us, we all have tried to be greedy and then nothing happened. So Do Not try to change anything other than what is instructed. Because if you do, it will not work for you. Remember, honesty reaps the reward!!! 1.... After you have ordered all 5 reports, take this advertisement and REMOVE the name & address of the person in REPORT # 5. This person has made it through the cycle and is no doubt counting their fortune. 2.... Move the name & address in REPORT # 4 down TO REPORT # 5. 3.... Move the name & address in REPORT # 3 down TO REPORT # 4. 4.... Move the name & address in REPORT # 2 down TO REPORT # 3. 5.... Move the name & address in REPORT # 1 down TO REPORT # 2 6.... Insert YOUR name & address in the REPORT # 1 Position. PLEASE MAKE SURE you copy every name & address ACCURATELY! ========================================================== **** Take this entire letter, with the modified list of names, and save it on your computer. DO NOT MAKE ANY OTHER CHANGES. Save this on a disk as well just in case if you loose any data. To assist you with marketing your business on the Internet, the 5 reports you purchase will provide you with invaluable marketing information which includes how to send bulk e-mails legally, where to find thousands of free classified ads and much more. There are 2 Primary methods to get this venture going: METHOD # 1: BY SENDING BULK E-MAIL LEGALLY ========================================================== Let's say that you decide to start small, just to see how it goes, and we will assume You and those involved send out only 5,000 e-mails each. Let's also assume that the mailing receive only a 0.2% response (the response could be much better but lets just say it is only 0.2%. Also many people will send out hundreds of thousands e-mails instead of only 5,000 each). Continuing with this example, you send out only 5,000 e-mails. With a 0.2% response, that is only 10 orders for report # 1. Those 10 people responded by sending out 5,000 e-mail each for a total of 50,000. Out of those 50,000 e-mails only 0.2% responded with orders. That's=100 people responded and ordered Report # 2. Those 100 people mail out 5,000 e-mails each for a total of 500,000 e- mails. The 0.2% response to that is 1000 orders for Report # 3. Those 1000 people send out 5,000 e-mails each for a total of 5 million e-mails sent out. The 0.2% response to that is 10,000 orders for Report # 4. Those 10,000 people send out 5,000 e-mails each for a total of 50,000,000 (50 million) e-mails. The 0.2% response to that is 100,000 orders for Report # 5 THAT'S 100,000 ORDERS TIMES $5 EACH=$500,000.00 (half million). Your total income in this example is: 1..... $50 + 2..... $500 + 3..... $5,000 + 4 .. $50,000 + 5..... $500,000 ........ Grand Total=$555,550.00 NUMBERS DO NOT LIE. GET A PENCIL & PAPER AND FIGURE OUT THE WORST POSSIBLE RESPONSES AND NO MATTER HOW YOU CALCULATE IT, YOU WILL STILL MAKE A LOT OF MONEY ! ========================================================= REMEMBER FRIEND, THIS IS ASSUMING ONLY 10 PEOPLE ORDERING OUT OF 5,000 YOU MAILED TO. Dare to think for a moment what would happen if everyone or half or even one 4th of those people mailed 100,000e-mails each or more? There are over 150 million people on the Internet worldwide and counting. Believe me, many people will do just that, and more! METHOD # 2 : BY PLACING FREE ADS ON THE INTERNET ======================================================= Advertising on the net is very inexpensive and there are hundreds of FREE places to advertise. Placing a lot of free ads on the Internet will easily get a larger response. We strongly suggest you start with Method # 1 and add METHOD # 2 as you go along. For every $5 you receive, all you must do is e-mail them the Report they ordered. That's it. Always provide same day service on all orders. This will guarantee that the e-mail they send out, with your name and address on it, will be prompt because they can not advertise until they receive the report. =========== AVAILABLE REPORTS ==================== ORDER EACH REPORT BY ITS NUMBER & NAME ONLY. Notes: Always send $5 cash (U.S. CURRENCY) for each Report. Checks NOT accepted. Make sure the cash is concealed by wrapping it in at least 2 sheets of paper. On one of those sheets of paper, Write the NUMBER & the NAME of the Report you are ordering, YOUR E-MAIL ADDRESS and your name and postal address. PLACE YOUR ORDER FOR THESE REPORTS NOW : ==================================================== REPORT # 1: "The Insider's Guide to Advertising for Free on the Net" Order Report #1 from: Mauricio V�lez SHIPNET 1-1158 PO Box 02 - 5210 Miami, FL 33102-5210 USA ___________________________________________________________ REPORT # 2: "The Insider's Guide to Sending Bulk e-mail on the Net" Order Report # 2 from: Oscar Bol�var SHIPNET8 1143 PO Box 02-5210 Miami, FL 33102-5210 USA ___________________________________________________________ REPORT # 3: "Secret to Multilevel Marketing on the Net" Order Report # 3 from: Monty Porter PO Box 1104 American Fork, Utah 84003 USA ____________________________________________________________ REPORT # 4: "How to Become a Millionaire Utilizing MLM & the Net" Order Report # 4 from: Melvin Manigault 104 Miller Ave. Lindenwold, N. J. 08021 USA ____________________________________________________________ REPORT #5: "How to Send Out 0ne Million e-mails for Free" Order Report # 5 from: Aaron Joseph PO Box 21155 Columbia Heights, MN 55421 USA ____________________________________________________________ $$$$$$$$$ YOUR SUCCESS GUIDELINES $$$$$$$$$$$ Follow these guidelines to guarantee your success: === If you do not receive at least 10 orders for Report #1 within 2 weeks, continue sending e-mails until you do. === After you have received 10 orders, 2 to 3 weeks after that you should receive 100 orders or more for REPORT # 2. If you did not, continue advertising or sending e-mails until you do. === Once you have received 100 or more orders for Report # 2, YOU CAN RELAX, because the system is already working for you, and the cash will continue to roll in ! THIS IS IMPORTANT TO REMEMBER: Every time your name is moved down on the list, you are placed in front of a Different report. You can KEEP TRACK of your PROGRESS by watching which report people are ordering from you. IF YOU WANT TO GENERATE MORE INCOME SEND ANOTHER BATCH OF E-MAILS AND START THE WHOLE PROCESS AGAIN. There is NO LIMIT to the income you can generate from this business !!! ====================================================== FOLLOWING IS A NOTE FROM THE ORIGINATOR OF THIS PROGRAM: You have just received information that can give you financial freedom for the rest of your life, with NO RISK and JUST A LITTLE BIT OF EFFORT. You can make more money in the next few weeks and months than you have ever imagined. Follow the program EXACTLY AS INSTRUCTED. Do Not change it in any way. It works exceedingly well as it is now. Remember to e-mail a copy of this exciting report after you have put your name and address in Report #1 and moved others to #2 ............# 5 as instructed above. One of the people you send this to may send out 100,000 or more e-mails and your name will be on every one of them. Remember though, the more you send out the more potential customers you will reach. So my friend, I have given you the ideas, information, materials and opportunity to become financially independent. IT IS UP TO YOU NOW ! ============ MORE TESTIMONIALS ================ "My name is Mitchell. My wife, Jody and I live in Chicago. I am an accountant with a major U.S. Corporation and I make pretty good money. When I received this program I grumbled to Jody about receiving ''junk mail''. I made fun of the whole thing, spouting my knowledge of the population and percentages involved. I ''knew'' it wouldn't work. Jody totally ignored my supposed intelligence and few days later she jumped in with both feet. I made merciless fun of her, and was ready to lay the old ''I told you so'' on her when the thing didn't work. Well, the laugh was on me! Within 3 weeks she had received 50 responses. Within the next 45 days she had received total $ 147,200.00 ........... all cash! I was shocked. I have joined Jody in her ''hobby''. Mitchell Wolf M.D., Chicago, Illinois ====================================================== ''Not being the gambling type, it took me several weeks to make up my mind to participate in this plan. But conservative that I am, I decided that the initial investment was so little that there was just no way that I wouldn't get enough orders to at least get my money back''. '' I was surprised when I found my medium size post office box crammed with orders. I made $319,210.00 in the first 12 weeks. The nice thing about this deal is that it does not matter where people live. There simply isn't a better investment with a faster return and so big." Dan Sondstrom, Alberta, Canada ======================================================= ''I had received this program before. I deleted it, but later I wondered if I should have given it a try. Of course, I had no idea who to contact to get another copy, so I had to wait until I was e-mailed again by someone else.........11 months passed then it luckily came again...... I did not delete this one! I made more than $490,000 on my first try and all the money came within 22 weeks." Susan De Suza, New York, N.Y. ======================================================= ''It really is a great opportunity to make relatively easy money with little cost to you. I followed the simple instructions carefully and within 10 days the money started to come in. My first month I made $20,560.00 and by the end of third month my total cash count was $362,840.00. Life is beautiful, Thanx to Internet.". Fred Dellaca, Westport, New Zealand ======================================================= ORDER YOUR REPORTS TODAY AND GET STARTED ON 'YOUR' ROAD TO FINANCIAL FREEDOM ! ======================================================= If you have any questions of the legality of this program, contact the Office of Associate Director for Marketing Practices, Federal Trade Commission, Bureau of Consumer Protection, Washington, D.C. ***************************************************************** This message is sent in compliance of the new email bill section 301.

ColdFusion - I want to remain a Zopista, please help
by Mojo Clark 28 Jul '01

28 Jul '01

This email I received from the head of our IS dept. explains my situation (posted with sender's permission after anonymizing it). ======================================================== As you are all well aware there has been a recent surge in the amount of web design work that staff has been seeking. This has brought to light the fact that we need to have a standard in web design software. I am referring to design software that takes us beyond the level of what programs like Dreamweaver and Front Page can do. I believe the two options we have here are Zope and ColdFusion. Please put together a list of pros and cons regarding what you would like to use to accomplish some of our more intensive web design tasks. Send your lists to me via e-mail by the 26th of July and I will compile them into something that we can sit down and work through and come up with a decision on what our standard should be. I have checked to see if [the parent company] has a standard and it appears that they do not as they do not have a true web design group. Due to the increasing amount of work, I would like to make a decision on this rather quickly so as not to delay the production of any projects. ============================================================ I've been a Zopista for about a year so I can address the benefits of Zope, but I am not knowledgeable regarding ColdFusion. What is driving the pro-ColdFusion push is our graphics department whose main web tool is Dreamweaver. They don't do dynamic web programming or database integration and it took some explaining to move the choice from Zope vs. Dreamweaver to Zope vs. ColdFusion. I am looking for reasons why Zope is a better choice than ColdFusion. Any knowledgeable responses greatly appreciated. I sense that using Zope would be a non-issue if the graphics dept. was assured that they wouldn't have to abandon their GUI-based design tools. Does anyone have experience collaborating with Zope where the non-programming graphics people are sharing the Zope interface? Have you been able to find a mutually agreeable arrangement? There has been plenty of discussion regarding "Zopeweaver" but it sounds like integration is limited. -mojo clark _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
