Terry 2-Feb-2010 [7868x4] | LFReD ported to websockets using the TTS from the demo. Opens up a whole new world. |
I already have a paid gig for it as well :) | |
It's a company supplying the Olympics, and needs audio feedback as it scans product out of the warehouse... "Im sorry, but that pallet does not contain all of the necessary product to fulfill this order. Please add 3 more units of spam, and have a nice day" | |
:) | |
Dockimbel 2-Feb-2010 [7872] | That's very good Terry! |
Graham 6-Feb-2010 [7873x3] | Does Cheyenne's url-encode function correctly encode something like this "==" ? |
I tried the url-encode from the repository ... and it does nothing. It should do this >> url-encode "==" == "%3D%3D" | |
http://www.google.com/codesearch/p?hl=en#8-MruDvODLg/trunk/UniServe/libs/html.r&q=url-encodepackage:http://cheyenne-server%5C.googlecode%5C.com&sa=N&cd=2&ct=rc&d=2 | |
Oldes 6-Feb-2010 [7876x2] | >> url-encode/all "==" == "%3D%3D" |
the switch /all includes also url-reserved: charset "&/:;=?@" as you can see in the code you have linked here:) | |
Graham 6-Feb-2010 [7878x2] | ahh .... |
so what's the point of not doing /all as default? | |
BrianH 6-Feb-2010 [7880x2] | Because those characters are url syntax, and encoding them would break the syntax. |
Particularly = and & would break url-encoded name/value pairs. | |
Graham 6-Feb-2010 [7882x2] | I encode each part of the url and then rejoin |
I guess his url-encode encodes the whole url .... | |
BrianH 6-Feb-2010 [7884] | Under those circumstances it's safe to se url-encode/all. |
Oldes 6-Feb-2010 [7885x2] | I do this as well with my own url-encode function as Graham as I consider it as more safe |
ech.. too many "as" ... must go to sleep :) | |
Oldes 7-Feb-2010 [7887x2] | What's the correct way how to deal with uploaded files? I mean... if I for example upload a very large file, then I must move it to correct location after upload is finished. What is the best way how to move a large file in the Cheyenne context? What about a possibility to set the custom %incoming/ location before download starts so no need for move will be required and we can just rename the file? |
I think that under Windows for fast file movement I can use: set 'MoveFile make routine! [ "Moves file using OS" lpExistingFileName [string!] lpNewFileName [string!] ] kernel32.dll "MoveFileA" But what about under Linux? Just a simple call? | |
Gabriele 7-Feb-2010 [7889] | RENAME, on same file system. if you don't want to care, call "mv" |
Gregg 7-Feb-2010 [7890] | And move-file won't be fast all the time. e.g. if you're moving the file to another drive. |
Will 7-Feb-2010 [7891x3] | here is from the change-log: RSP: new method 'store added to Request object. It simplifies uploaded files management by abstracting file's location (memory or disk). Example: request/store request/content/file %attached/ will save the uploaded file passed as "file" query parameter in %attached/ folder using the original name (!!watch out for security issues!!). request/store request/content/file %attached/my-file.bin will save the uploaded file with a forced name (original name needs to be saved separatedly if needed). |
latest svn use rename instead of call "mv xx".. | |
code is in cheyenne/handlers/RSP.r | |
Dockimbel 8-Feb-2010 [7894] | I'm currently reworking the response/store function. I'm considering dropping in-memory uploaded files mode, it was supposed to help processing uploaded data files (think CSV files for example) avoiding the disk write/read part, but it just adds complexity for a marginal gain. If anyone found that mode useful, please say so now. |
Oldes 8-Feb-2010 [7895x2] | I think the in-memory mode is not much needed for me. I was a little bit suprised why some files are in memory and other on disk. And usualy you would like to store the original file (for example the csv) before processing anyway. |
With the request/store - does it means that the rsp processing starts before the upload is finished = stops where the /store is called waiting on upload finish? | |
Graham 8-Feb-2010 [7897] | well, I have routines to check for in memory or on disk receipt .. |
Oldes 8-Feb-2010 [7898] | And do you save the in memory content? |
Graham 8-Feb-2010 [7899] | Usually do save it to disc ... |
Dockimbel 9-Feb-2010 [7900] | When uploading a file, the RSP script is called when the upload is completed. |
Terry 11-Feb-2010 [7901] | speaking of uploads.. try it with this.. http://www.plupload.com/example_queuewidget.php |
jrichards 12-Feb-2010 [7902] | In the config file is worker-libs contained within globals or should it be preceding globals. Trying to get mysql working. |
james_nak 12-Feb-2010 [7903] | If you're referring to the httpd.cfg file, I don't have any references to mysql except for those referring to actual databases. What I did to test mysql was use the rebol mysql driver (in a normal rebol shell) outside of the Cheyenne environment to make sure it worked. Hope that helps. |
Dockimbel 12-Feb-2010 [7904x2] | Jim: 'worker-libs have to be declared inside 'globals section of config file. |
I usually load mysql driver from a local Cheyenne libs/ sub-folder : globals [ ... worker-libs [ %libs/mysql-protocol.r ] ... ] | |
jrichards 12-Feb-2010 [7906] | Thanks Doc, I did get it running with some simple selects and updates now I just need to learn how to format the returned data. This is good stuff. By the way I am using the do-sql method and works great. |
james_nak 12-Feb-2010 [7907] | Doc, I wonder if that is my problem. I don't have worker-libs my httpd.cfg file. |
Dockimbel 13-Feb-2010 [7908] | James: it's not mandatory, you can load mysql driver from 'on-application-start event for example (but you'll need to do that for all your webapps). It's just simplier to declare it in config file once for all. |
james_nak 13-Feb-2010 [7909] | Got it. |
Carl 13-Feb-2010 [7910x2] | I want to move DevBase (R3 Chat) to Cheyenne, but I must admit that I am a newbie with Cheyenne. Currently the code runs as a process, and we tunnel packets thru HTTP via Apache. However, I could run it as a persistent process in Cheyenne, or via some method that would simply put the http input and output into a socket. Anyone here know how this is done? |
(BTW, I'm doing this to move DevBase to the new Linnode server... to offload it to a faster location.) | |
Graham 13-Feb-2010 [7912] | Is this why chat is down now? |
Carl 13-Feb-2010 [7913] | I've not shut it down yet. But, I've been having difficulty connecting to that server all day. It's probably under 10 feet of snow. |
Graham 13-Feb-2010 [7914x2] | If it's running as a single process .. that won't scale very well will it? |
Wonder how much slower it would be if you ran it as rsp scripts | |
Carl 13-Feb-2010 [7916] | It scales very well... as long as it has a web server sitting in front of it. |
Henrik 13-Feb-2010 [7917] | as a cheyenne app it probably would run faster |
