searching a ZCatalog

Hello list, Happy New Year! Sorry if I already posted this msg, but I didn't see it so I think that was another malfunctioning of my mailer. I gave a ZCatalog and I perform searches on the PrincipiaSearchSource field. I modified the results table so that it shows links to the found occurrences, not just blackon white results Now what I'd like that when I click on one of those links, the file that opens has the occurrences highlighted somehow, say: blah bla blah occurrence blah bla blah Anyone would suggest me how? Thak you so much Bye Catonano __________________________________________________________________ Tiscali ADSL: abbonati entro il 31 gennaio. Non paghi l'attivazione.

AdaptableStorageProduct: RuntimeError
by Elena Schulz 03 Feb '03

03 Feb '03

Hi Shane, in my ZMI there are two folders: pathA and pathB and I use your AdaptableStorageProduct for FileSystemStorage with the two mount_paths=/pathA/zptTexte; /pathB/zptTexte so that the zptTexte get mounted to these Folders in the ZMI. It works initially but when I try to copy anything in the pathA-Folder in the ZMI , I get a RuntimeError. Same happens as soon as I try to enter the folder pathA in the ZMI afterwards. Is there any solution for that? Or can use only one mount_path? -- many thanks for your replies, Elena Error Type: RuntimeError Error Value: Shouldn't load state for '(\x01\x00\x00\x00s\x18\x00\x00\x00/project_health/zptTexte' when the connection is closed Error error_tb: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module App.special_dtml, line 174, in _exec Module DocumentTemplate.DT_In, line 705, in renderwob Module Products.AdaptableStorage.zodb.ASConnection, line 302, in setstate RuntimeError: Shouldn't load state for '(\x01\x00\x00\x00s\x18\x00\x00\x00/project_health/zptTexte' when the connection is closed

Hardware for Zope + ZEO
by Wankyu Choi 03 Feb '03

03 Feb '03

Dear all, I'm planning to rebuild one of my commercial portal sites using Zope with more than 300,000 users. The portal has been running on APM( apache + php + mysql ) without a glitch for three years. I've been worried about Zope's scalibility since I already have too many users with as much data. I came to a conclusion that ZEO might help with a bit more hardware thrown in. Here's my plan. (OS: Linux) 1. Get a rock-solid machine for ZEO server: Intel XEON dual cpus (SR2300 if you want to know this Intel server model) with 2G mem + six 73G segate SCA scsi hard disks + RAID5 for fault-tolerance (intel srcu32 dual channel raid controller) 2. Throw in at least three less-powerful machines for ZEO clients: 1 P3 tualatin + 1G mem + 1 36G hard disk with NO RAID. I plan to buy one No.1 machine plus one No.2 machine since I already have two machines, candidates for the other two ZEO clients. I came under the impression using Zope for the past year ( and from python/zope docs ) that python uses only one CPU no matter how many I have. One of the two machines I already have has four Xeon cpus but Zope on that machine runs way slower than one on my single P3 desktop with a bit more horsepower. Suppose you have 300,000 users with tons of data and expect they'd start adding tons more data once you open this portal based on Zope + heavily customized CMF/Plone. Would this setup seem reasonable? Or better still, how would you set your portal up if you got extra dough for hardware? Specifically I want to know... 1. Would the above setup seem reasonable? 2. Some say P3 tualatin is better for Python than P4 or even Xeon processors. Is that true? 3. I'm looking towards the Directory Storage over File Storate for tons of reasons, the reasons you might easily guess. I'll have six 73G disks with RAID5, which means I'd have to let go 73G for storing parity information. That leaves me about 365G. At least 300G will be allocated for ZODB. Would FileStorage maintain its integrity if the db grows to 300G? What I'm worried about most is that I can't make it versionless. Directory Storage has that option. Comments? 4. Would I really get no benefits from running Python on SMP machines? That is, would I better off with two 1 cpu machines than one dual cpu machine? If true, do I really have to buy Dual XEON intel server for ZEO central storage server? Why don't I just settle for a single CPU machine for that with more RAM? 5. Can I run a ZEO client on ZEO server? To sum up, I'd get a total of four machines: one ZEO server and three ZEO clients. I want to make it four clients. I assume I can also run a ZEO client on the ZEO server but I hunch that some would probably say no to that... . May I ask why? 6. You have the following machines. How would you set up your ZEO server and clients? Remember, you have 300,000 users eager to add data :-) Machine No.1 - 2 Xeon 2.0GHZ CPUs + 2G mem + six 73G disks + Intel high-end RAID controller Machine No.2 - 1 P3 tualatin CPU + 1G mem + 1 36G disk Machine No.3 - 2 Xeon CPUs (older model) + 1G mem + 3 36G disks (disks old, will be recycled for backup storage or something) Machine No.4 - 4 Xeon CPUs (older model) + 2G mem + 4 36G disks (disks old, will be recycled for backup storage or something) I'd appreciate any comments.

TAL: test() or condition Howto?
by Elena Schulz 31 Jan '03

31 Jan '03

Hi, I have the followong TAL-expression: <td tal:content="structure python:here.test(myImportantCondition and myExpensiveMethod(), myExpensiveMethod(), 'myDefaultString')">myDefaultString</td> To execute 'myExpensiveMethod()' 'myImportantCondition' must be 'true'. But I want to avoid to execute 'myExpensiveMethod()' two times. How can I achive that? As default-value myDefaultString should be served. I don't know a way with tal:condition 'cause on 'false' there is no way to get 'myDefaultString', isn't it? -- many thanks for your replies, Elena

RE: [Zope] Re: ZODB file size
by sean.upton＠uniontrib.com 31 Jan '03

I think I might also have seen a situation where dd worked to create a large file but tar didn't and ls output an incorrect file size (this was on Debian Potato / SPARC with a 64 bit 2.2 kernel and 32 bit user-space, likely becuase the C library didn't have LFS support and/or the apps I was running as compiled didn't use it). Making sure that your C library, kernel, and Python, and other tools have LFS support is a pain enough, but this is generally solved for you with any newer Linux distribution like Debian 3.0 (Debian python2.1 packages have LFS support - I have had 3-4 GB Data.fs files on a recent Debian box) and newer versions of RedHat.

Yes, but it won't be enough if your linux doesn't support it. In this case you can try to use external access products like LocalFs, AdaptableStorage (Not sure about the spelling), ExtFile-ExtImage, DirectoryStorage, etc.. Or enabling Large File Support in your linux by migrating to Reiserfs (from suse), XFS (from sgi), JFS (from IBM), Ext3fs, etc.. An easy way to know if your linux support large files is to type: dd if=/dev/zero of=big_file_test bs=1024 count=2600000 * Make sure you have at least 3Gb free space. It will try to create a file (big_file_test) bigger than 2Gb. If you see: "File too large" it means your system doesn't support large files. Then, with the file you just create, you can follow this instructions to check if your python support LFS: http://www.zope.org/Members/beacon/install_instructions > And maybe check the mailing list > archive > since this question has been asked and answered several times. This one helps too ;) and perhaps checking linux newsgroups.
