Re: Amazon Linux 2023

[Jesse Tayler via Webobjects-dev]

I’ve been using containers which are helpful in controlling the administration 
without need of knowing much about the host environment.

Re: enumerating sessions?

[Jesse Tayler via Webobjects-dev]

Off the top of my head? I’d not use sessions for that — I’ve done some bank 
apps where only one session is allowed and some other stuff, but we avoided 
relying on or tracking sessions, rather we build a login scheme that tracked 
this concept specifically and we let session and cookies stuff be.

Keep us posted.

Oh? I figured nobody changed that adaptor since forever ago — 

Maybe I should download that first before updating?

Re: RDS [was: Re: WOLips Update]

[Jesse Tayler via Webobjects-dev]

I’m upgrading from a rather old MySQL, this is basically a button press and I 
suppose I should dump the data in case something goes awry but I cannot see why 
my boring EO Model would have any trouble using an updated version even if the 
jump is — well, at least like…I dunno - ten years? 

The database doesn’t get a lot of touching!

But this version is out of date, so I figure people would have reported if 
there were ever some trouble encountered.

Does anyone use RDS on AWS?

Re: AjaxAutoComplete

[Jesse Tayler via Webobjects-dev]

I have used Ajax quite easily on a couple of components and for some reason, 
implementing even the simplest test was failing on updating a component of a 
similar sort.

Before I make a wholly new component — are there flags or tests aside from 
jQuery which seems fine? I don’t readily see why this just isn’t seemingly 
observing and updating the way I expect?

Thoughts?

Re: WOLips bugfixes and new features planning

[Jesse Tayler via Webobjects-dev]

Nobody wants to fix that plugin, if I hadn’t tried to hire someone myself I’d 
not believe it.

I guess I don’t care about eclipse, but there doesn't seem to be any reason to 
leave it either.

I still hope we can fix these remaining issues in WOLips, it has been there for 
us for so long...

Re: WebObjects Docker Deployment

[Jesse Tayler via Webobjects-dev]

Um. The app is mostly session stuff, there’s a few routes but I’m not thrilled 
with the way it is handled and you still have those pages with the weird dot 
notation in the URL…

I use ERRest and it’s great, I’m not certain if session objects are created 
during requests, but it won’t have any need for sessions.

My WO stuff is a little old-school style I’m afraid.

That said, I’d like to improve that stuff!

No idea really — Did you make clean first? Do you have specific JAVA versions

Re: [Proposal] Drop Wonder's Ant Build

[Jesse Tayler via Webobjects-dev]

I admit I’m only half following this thread but I am still using Ant right now

from where I was at

Are we considering removal of ant as an option?

Re: owns destination + deny prohibited?

[Jesse Tayler via Webobjects-dev]

You are missing the code to do just that policy. The model rules are simplistic 
and so owning means it owns and removes so your rules don’t work together but 
you’d be needing and wanting to trigger that delete with your own policy and 
code

Re: WebObjects REST vs Node Multithreading

ERRest + ERXKeys is just plain solid stuff, I can tell you that I like it very 
much, the compiler is deeply involved in structure and so if you are looking 
for reliable infrastructure? It’s hard to beat ERRest in my book.

Re: Single thread creation queue?

[Jesse Tayler via Webobjects-dev]

Thanks Ted, actually I was looking to see how to make a compound constraint - 
one static string type=“twitter” and I guess a lowercase version of a 
user-entered display string keyStringToLowercase = username and the only way I 
saw to add that into migrations was to write SQL and inject it?

But I did NOT know how to adjust those error strings! I have several bothersome 
error reports so, you’ve opened my eyes! I’ll look into that .strings key stuff 
there and see if I can figure that out. I might ping you about it...

Re: Single thread creation queue?

[Jesse Tayler via Webobjects-dev]

A collation would also work, I don’t think there’s a need to preserve case but 
I guess I have thus far and perhaps that’s an easier route than attempting to 
alter data in place, I could simply add the function in a way it can blend in 
perhaps.

I tried to find a decent wiki page, but does anyone have good examples of 
migrations that add constraints or do fancy stuff? 

Do I have to stuff raw SQL into a migration or are there functions I can’t see 
in there--

Re: Single thread creation queue?

[Jesse Tayler via Webobjects-dev]

so, basically, you are suggesting that I store them flat lowercase and put a 
constraint on these two strings and just lose any case the user entered which 
is fine I think.

With the lowercase assured the constraint will prevent duplicates and I’d catch 
that exception during creation and handle it

So, I fetch first

EOQualifier qual = 
DataPoint.TYPE.eq("twitter").and(DataPoint.KEY_STRING.likeInsensitive(username));

If there’s no EO, I create and save right away but at high volumes this CREATE 
statement must create only unique entries and those entries must match this 
qualifier which uses insensitive case

I figure the pattern should be to create an object with a DB level constraint 
such that a duplicate raises an error, upon catching that error, I can simply 
fetch again and return the one, single EO representing that record

When I tried regular constraints I did not see a way to replicate the required 
logic, so I found some advise about triggers and some other things I didn’t 
fully understand.

I realize usernames generally have this kind of issue, so I figure this is a 
design pattern that is hardly unique to us and I should get advice!

Re: Single thread creation queue?

[Jesse Tayler via Webobjects-dev]

Ok wait — I have a question

I see my qualifier and the constraint needs to be equivalent 

The qualifier has one fixed string and the second string is — case-insensitive 
— constraints don’t seem to allow this notion?

I see a several suggestions on what is clearly the same, common issue - often 
usernames have this quality

https://stackoverflow.com/questions/637030/lowercase-constraint-sql-server

Anyone have insight?

Re: Single thread creation queue?

[Jesse Tayler via Webobjects-dev]

Oh? Thanks - I hadn’t heard of such a thing. This would be Amazon RDS which is 
basically MySQL and likely has similar.

Either way I guess I should delete any dups, they either cause an error 
somewhere or at least integrity problems I don’t need.

Is there a good wiki page on migration examples out there?

Re: Single thread creation queue?

[Jesse Tayler via Webobjects-dev]

It’s not a compound key so much as just policy — it’s a handle for social 
service and so there should just be one row with that value and don’t need to 
tie into the key

I guess I can create a unique index just for that one attribute and it would 
presumedly return an error upon save. I should re-write the EO to handle that 
error raise and respond by returning the existing object…

I guess that is not hard to figure if that approach sounds sane.

I do have dups and I’d guess the constraint will simply fail if the database 
has any dups in it.

I guess writing a migration to handle / remove dups is not practical so I’d 
likely remove them by hand, then add the constraint in a migration update that 
would gently fail until there are no more dups…

Re: Single thread creation queue?

[Jesse Tayler via Webobjects-dev]

It’s likely just a unique constraint perhaps.

It’s not UIDs or primary keys it’s a unique row type based on a couple strings 
where there should be only one, and that one should last forever.

There’s an API where calls can come in basically at the same time and instead 
of fetching first to see if the object exists, I should likely respond to an 
SQL error rejecting a new row and then fetch and return that existing object 
based on that error condition.

I’d suppose the database is the best place for that policy, but I don’t think 
I’ve implemented constraints quite like that before so I’d need to write some 
sort of Migrations for it if it’s to be reliable in all those situations where 
it might encounter duplicate data…hmmm…

Single thread creation queue?

I asked on slack but I figured I’d ping the list

Who has a good way to ensure a serial EO creation queue when the system could 
be hit really fast and you must avoid duplicate entries?

I’m a bit surprised I don’t recall EOF style solutions for such things and 
maybe the Amazon RDS database has a shared connection pattern the apps can use, 
I didn’t see anything so I figure this is application level stuff.

HA! Good, well then something good comes of it!

Monitor should not be in itself but should be run and left running, mine is 
only available via IP:port and not via domains.

I’d remove it from itself because that’s not needed and I guess if it ever goes 
down for some reason, I’d log into the instance and spark it up which is all I 
did for wotaskd

I noticed a startup script with basically two lines, one to start wotaskd and 
the other to start monitor, so I can always look there if it is not running.

One of my servers is running ok, but JavaMonitor isn’t getting any contact with 
what I guess must be wotaskd?

Any suggestions or seeing what might be down or how to get that back up most 
properly? I see some notes in the wiki but nothing seemed like a ringer and I 
can’t recall ever having this happen before? 

Maybe it’s no worry.

I notice I seem to have JavaMonitor running inside JavaMonitor which I guess is

Re: macOS deployment?

[Jesse Tayler via Webobjects-dev]

It’s not an ecosystem, it’s a container.

You contain your entire deployment and this makes it portable so that it acts 
the same on your desk as as it does on the cloud or anywhere else the container 
runs.

What is it you need for deployment specifically? Or, why is running the app at 
your desk insufficient?

Re: WOLips bugfixes and new features planning

[Jesse Tayler via Webobjects-dev]

I sure look forward to a refresh, not sure why but my current install often 
renders wrong, or basically you have to assume a file is what you expect and 
double-smack and then it draws the fresh name but mostly it is stale screen 
dirt leftover from whatever was there before…

Re: Licence for WebObjects

[Jesse Tayler via Webobjects-dev]

Ya, the answer is don’t worry about it.

Apple long since dropped support and that’s that. Don’t call it “WO” just say 
it is JAVA, there’s really very little “WO” but for the app server part

Re: Quick Q regarding D2W smartAttributes

[Jesse Tayler via Webobjects-dev]

Just as a thought, I look and noted I have a component rule for boolean in my 
app with much the same logic at 100 priority. This suggests you’ve just got 
some OTHER rule cranked up and don’t forget that rule could just be VERY strict 
with greater specificity vs. priority.


100 : (smartAttribute.className = 'java.lang.Boolean' and task != 'edit') => 
componentName = ERD2WCustomDisplayBoolean

Re: Quick Q regarding D2W smartAttributes

[Jesse Tayler via Webobjects-dev]

Did you make certain your className does indeed report as that form of boolean? 
These things resolve from your model and you can fish around those attributes 
for information.

Honestly, I’ve found that in these cases with D2W I resort to simply reporting 
things from the D2WContext right onto the display (since you are a list there, 
put a string reporting values into your html repetition there)

You should also generally open up the various D2Ws loading from frameworks to 
see where your last firing rule really is.

Although there are better tools for this, I never really learned to use them - 
more like avoid these things where I can and generally just interrogate at 
runtime to see what rules are firing and what values are in the context and 
when.

I’m sure others know how to use the rule firing tools in a more suitable manner.

Re: The secret WOCommunity Slack channel?

[Jesse Tayler via Webobjects-dev]

Even if we replace the footer of this email list with links to other resources 
— we don’t need to reflect all the conversations, but folks should have equal 
visible access to all the places information is.

I have also not found anything to really store new stuff in, WIKIs SUCK!! They 
are ugly and lame like we’re back in the 90’s

The new stuff I see, google docs — these are thoughtless ideas that are hard to 
give a place on the web— a domain or even a strong page somewhere.

Maybe we should use GITHub more?

I have all this container deployment stuff I can push he documentation and 
instructions for online, but we have to find a decent location people can 
access…

Suggestions?

Re: Webobjects-dev Digest, Vol 17, Issue 168

[Jesse Tayler via Webobjects-dev]

Is it not possible to make it public?

I think I tried to get in, but honestly, I have so much trouble logging into 
slack with their truly bizarre idea of how to find what channels you belong to 
and log them in on each device you use…a super pain in the butt.

Also, does slack integrate with emails lists such that we can bind these two 
tougher so we all communicate as one list?

Re: The secret WOCommunity Slack channel?

[Jesse Tayler via Webobjects-dev]

This Wiki is disgusting.

Firstly, it looks like ass. 

Secondly you have to edit in bare-knuckles wiki script which is arcane and 
silly.

The world can’t be like this!

Surely, there is some nice looking software you can easily cooperatively edit 
and add photos or whatever links…and don’t say google docs!

Maintaining stuff like this wiki thing is for the birds.

Re: The secret WOCommunity Slack channel?

Well I was able to get MediWiki up and running and I can post that and start 
off a new party with modern-only information.

I was not able to load the bootstrap framework and the look of these wikis are 
eye-watering.

https://www.mediawiki.org/wiki/Extension_talk:Bootstrap

Anyway, I can try that or if someone throws me a bone on some better idea I can 
try that as well.

Re: The secret WOCommunity Slack channel?

[Jesse Tayler via Webobjects-dev]

I think “wiki" itself works well for this, real-time chat and pages where we 
can use images and formatting and various linking and keep it simple. A little 
less ‘moderated’ and a bit more a shared scratch area people can post whatever 
they think is useful.

I also agree the old stuff is more outdated or misinformation and really we 
should just start again.

Where can we put this sort of thing? A free wiki service or install one on a 
server? I guess I could set something up--

Re: The secret WOCommunity Slack channel?

[Jesse Tayler via Webobjects-dev]

I hate slack but we could use a channel like that, I worry about any form of 
divergence because we’re already few and far between

I have had great luck with Docker and WO and have a few modern frameworks that 
help keep our apps nicely modern and I’m actually really happy with the results 
so I still love WO and haven’t found anything I could wield that kind of power.

I should put the Docker stuff into a WIKI page, but I’m also wondering about 
the ‘old’ wiki and who’s maintaining any of that or if we should largely start 
again or something.

Ideas?

Re: Simplifying Wonder

[Jesse Tayler via Webobjects-dev]

Are we talking bifurcation of the root here?

I mean, as long as we’ve lic. code such that it allows us all to freely 
contribute, clearly open-source- we can work things out, but could this not 
make things more complicated for the community?

Also, what are you targeting? I have my own list of grievances but have a 
limited ability to address them because they are DEEP — So, I have a 
framework that my apps are based on to try to modernize and organize and it is 
effectively a ‘patch’ system to try and work around the problem I have and get 
me to a modern interface I can rely on.

Here’s my ‘modern’ look framework

https://github.com/jtayler/BootstrapModernLook

This approach patches on top what you suggest is of course a preferable 
solution, but one that I could not afford the resources to do.

Actually the Ajax.framework is totally cool but built on prototype and the 
internals are just so funky that I was unable to move to modern stuff and 
there’s actually a pinch of javascript in bootstrap modern that allows me to 
trigger menu actions and other things that generally don’t work on Wonder when 
you want to use jQuery based interfaces.

Your solutions may vary!

I’d love to get us all closer together on these central issues like updating 
the Ajax frameworks or WOLips progress because they benefit us all

Re: Headers and AJAX?

[Jesse Tayler via Webobjects-dev]

Right, so CORS is basically a browser thing and thus my command line or mobile 
app requests have all worked

So, I added in my virtual host apache configuration

Header set Access-Control-Allow-Origin "*"

But I’m not sure that’s allowing the headers through still?

Imagine a node.js server will just hit an API->JSON and I need to get a Key 
privately from that request

I realize I’m just using those javascript fiddle editor things like postman or 
whatever which I suppose isn’t entirely the same as a node.js request from a 
server since I guess the request is coming out of the web page/browser in those 
cases.

hmm…

Headers and AJAX?

[Jesse Tayler via Webobjects-dev]

I have relied on passing auth keys in headers from mobile apps and scripts.

I can even stuff a header into a curl statement

curl -H "Authorization: MY_PRIVATE_KEY"

In WO I can simply ask

request().headerForKey("Authorization”);

And I get that key,  always works as I’d expect

now I’m testing some AJAX and I see a few things

1. It makes my header lowercase?
2. I can print out all headers and all keys from WO and I can see my header 
listed but I’m never able to read it? Even if I use lowercase or change keys I 
never get a header in WO when I send it from AJAX

How could this be?

Is this some OTHER form of header or something?


I try a few ways to insert headers all to the same effect



beforeSend: function (xhr) {
xhr.setRequestHeader ("Authorization", "MY_PRIVATE_KEY”);
},




Or--



headers: {
 "Authorization": "MY_PRIVATE_KEY”,
"my-second-header": "second value”
},

Re: How to Manually edit SiteConfig.xml

[Jesse Tayler via Webobjects-dev]

I was thinking I could stub out the scripts I’m using, some are quite generic 
some just have some handy little parts to them.

Maybe there is a good wiki area I should use? 

What I think is best is if those of us interested can all basically call upon 
the same stuff and share best practices as we go,

Re: How to Manually edit SiteConfig.xml

[Jesse Tayler via Webobjects-dev]

I’ve picked up that very same docker and can’t quite edit that original it but 
I do have one based on top of it.

Adding Python3 and ImageMagic and a couple tools like S3 bucket stuff for AWS, 
this builds our entire environment.

https://hub.docker.com/r/truanon/server

I find this container to work great with WO— from load balancing to spinning up 
new instances it is testable and reliable.

Robert Hannah and I have worked out a GREAT deployment using GIT where the 
files end up being right where wodocker mount points are, and with a 
"user-data" script to start off the EC2 instances -- I run a single script to 
configure the whole thing from keys to the app to the containers, 
configurations, javamonitor setup. Done and starts up on its own, reliably, 
from scratch.

I’m happy to share any or all of these config files, we’ve been delighted with 
the results so far!

I think we can all pool together our docker related configs and create a 
baseline everyone can benefit from

Re: Monitor problem

[Jesse Tayler via Webobjects-dev]

You do have to have some args I think to tell monitor and wotaskd to spin the 
instance and all that.

As to why it would not start? That doesn’t sound good and you should try to see 
what went down — RAM? Who knows…

Look for clues in logs or other

Re: Apps not showing in adaptor info but are in WOMonitor

[Jesse Tayler via Webobjects-dev]

Well, I don’t know but each app has a port assigned and you should see that in 
monitor and in ps -axww or whatever you should be able to see which instances 
are which.

You should be able to hit instances specifically using a URL with the woport 
somehow on the URL, perhaps someone recalls or you can look that up.

But from the sound of it, those tools should tell you what instances are in the 
load balance or not.

Interestingly, I was able to find these scripts on my production server still 
sitting there.

And they did indeed do a lot of fun and interesting stuff.

I can see there’s an Adaptor in Wonder for apache but I was totally unable to 
build the mod_WebObjects.so and get apache running and that’s where I’m at now.

I should just be able to download the binary from a build somewhere shouldn’t I?

Same

I hack a bit further and might get through but I still hope some’s got working

If not, we’ll make one!

Re: New installation fail?

[Jesse Tayler via Webobjects-dev]

Well, it seems I was able to find some decade old scripts that had a LOT of 
important things in them all working at one time.

This fails in several ways like not finding this public S3 bucket or 
dependencies and I figure other folks must rely on EC2/S3

I can make sure I script out whatever I eventually get working for it but me 
thinks other folks are using something else or maintaining their instances 
another way?

New installation fail?

I'm launching a new EC2 Instance and just installing from scratch and I found 
my way to this page

https://wiki.wocommunity.org/display/documentation/Installing+a+deployment+environment+on+RedHat%2C+CentOS+or+Amazon+Linux

These WO installs all have bad links or dead services?

sudo yum install wotaskd
sudo yum install womonitor
sudo yum install woadaptor


I notice there’s stuff here

https://packages.wocommunity.org/CentOS/latest/i386/

I'm not even certain I recall what CentOS is, I’m apparently on Amazon Linux 2

Ok, so what’s the latest working method for updating an EC2 instance?

Re: Apache rules and SSL

[Jesse Tayler via Webobjects-dev]

On the way I notice that some URLs don’t honor secure

String link = context().directActionURLForActionNamed("dash", 
null);

I should be using a Wonder API for a regular DA url? Odd I was using that…

Paul?

Redirect permanent / https://foo.example.com/

Sounds smart — but doesn’t that simply change the entrance vs force ssl/https 
version of all urls?

Apache rules and SSL

[Jesse Tayler via Webobjects-dev]

I use AWS+Route53 for SSL and I really just want to force all requests to HTTPS 
and I’m having trouble

I have a few common WO rewrites to shorten URLs


RewriteRule ^/signup /apps/WebObjects/MyAppName.woa/wa/signup 
[last,passthrough]
RewriteRule ^/default /apps/WebObjects/MyAppName.woa/wa/default 
[last,passthrough]

RewriteRule ^/myappname(.*)$ /apps/WebObjects/MyAppName.woa$1 [PT,L]


And I seem to have these SSL related:

RewriteCond %{HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]



And no matter how I try to program this, I get too many redirects because 
apparently my rules run a loop or something?

Basic redirects are not unique to WebObjects!

How are you guys programming apache to shorten URLs and also bounce to SSL if 
it is not already?

add an onClick to a CCSmartAjaxButton?

[Jesse Tayler via Webobjects-dev]

I notice that if I bind an onClick to a CCSmartAjaxButton I don’t see that tag 
in the DOM later

Leading me to think it was stripped

Leading me to wonder if you can use javascript in the href as the 
CCSmartAjaxButton does and still have an onclick behavior?

I'm really just trying to make sure my form submit buttons generally do some 
fancy animation while loading…not a high priority

Anyone know what’s up with that?



SaveButton: CCSmartAjaxButton {
action = submitAction;
onClick = "setLoading()";
alt = "Saves your changes";

Re: Storing serialized object in MySql Database

[Jesse Tayler via Webobjects-dev]

hmmm…what’s your model look like? Or how are you setting up the storage of that 
data?

Sounds like you want a string and might watch the encoding of it before storage 
— 

It sounds perhaps like this error could occur because your data types are 
mismatched in a way that results in a validation error that doesn’t sound 
helpful or familiar…

Sometimes databases or models have fancy options when really you just need a 
string and it’s no big deal and so, you might look that over for sanity...

Re: Storing serialized object in MySql Database

[Jesse Tayler via Webobjects-dev]

Well, I’m sure there is validation for JSON since that has issues with format 
and encodings, so I’d expect some of that sort of thing here.

I don’t really see the value or whatever expected type, so I’d find that value 
that breaks it and test it —

One thing I wonder is about text encoding, are you certain you’ve got all your 
types correct?

I mean, it is gaging on a value somewhere, it could be a small as an invalid 
character or sequence.

Re: How often do you bounce your apps?

[Jesse Tayler via Webobjects-dev]

What do you use to keep an eye on memory? JAVA has such an old-school approach 
with the VM I use AWS and really don’t have any good automated visualizing 
report on how instances or JAVA is running under the hood.

My apps seem to run for a long time as a few times my scheduler has failed and 
they racked up 10X or even 100X normal sessions, but who knows what the user 
patterns were really — I have had to increase my JAVA VM and set memory stuff 
from JavaMonitor to keep things sane.

Re: Creating a EOModel in code

[Jesse Tayler via Webobjects-dev]

Nothing stops you from connecting to the database however you’d like. I can’t 
quite imagine what scenario a user would enter the full connection dictionary 
or how an app would then connect to a database that is somehow ‘unknown’ or 
introduced by the user, so maybe it’s just hard for folks to get an idea of why 
this would exist in the first place?

I'd elaborate on your goals rather than your chosen course of action because I 
don’t think it’s easy to imagine for folks to help you.

so, my simple EOF/ERXKey qualifiers and stuff would work, I’d use EOModeler?

 Hi Don,
 
 Have a look at EOEntity and friends: EOAttribute, EORelationship. 
 
 You can build them out and setup the “external” name for the column, etc. 
 I did it once as an exercise many moons ago. The only practical use I got 
 out of it was sometimes sanity checking keyPaths to see if they hit things 
 “in memory” or if they were completely traversable through EOEntity 
 relationships. Something that trips an in-memory method call is not 
 something you can use to build a complex SQL query. 
 
 Like other people have said, the “reverse engineering” of the original WO 
 tools is more likely what you want to use instead. You point Entity 
 Modeler at a database and it can make a surprisingly good model file from 
 it. Depending on how big the database is… it might be worth your trouble 
 of firing up MacOS Tiger and installing the NeXTStep GUI tools to do the 
 reverse engineering. I don’t think that the Eclipse java based 
 EntityModeler can reverse engineer. I don’t know if Cayenne can reverse 
 engineer.

Re: Strange null pointer error

[Jesse Tayler via Webobjects-dev]

Heh, ya, I figured you’d say that…and who does? I’m sure someone…

If you don’t have a clue, read your SQL and find those timestamps and see what 
transactions were going on.

If you can’t reproduce it, I’d guess you’ll want to turn up a bit of logging 
and just do a "hunt and peck” until you see where it comes from.

I'm not aware of any EOF type bugs relating to such things, but maybe others do.

Re: Creating a EOModel in code

[Jesse Tayler via Webobjects-dev]

You can generate your model based on your data-schema. I think that’s what you 
want, but you can also create entities in memory and relate them by hand but 
I’m not sure how that would result in a model file if that’s your goal.

Re: Entity/attribute/relationship terrible toString?

[Jesse Tayler via Webobjects-dev]

EOF uses this template system -- don’t think of it as generated code but rather 
boiler plates no different than using Wonder or even a library to do math.

Read the code and you’ll see it’s quite intelligently surrounding your object 
model with useful, reliable foundations that are valuable.

Your model is text, this needs to reflect as an object in memory and this 
template bridge starts off that process for you in a way that makes sense and 
you’ll find useful for sure.

This means the user has to invoke a new session by getting a link in email each 
time they access? 

I suppose that link cannot be shared since it expires?

I mean it sounds interesting, I am interested in what is going on with your 
suggestion.

Just seems like sending around links that allow people to enter directly has 
various dangers and complexities itself, and I wonder what the resulting 
experience is and what the level of security is. 

Isn’t this technically pushing the password back to your email login and isn’t 
that really no different than the O-Auth or Apple sign in? 

Apple sign in is preferable to users because it is easy and doesn’t offer 
private information to the site, Facebook login seems the same but is reversed. 
Facebook login is there to let Facebook see where you login and when so it can 
sell that data to advertisers.

The idea of not using passwords at all is interesting, but I’m not sure this 
would be what I’m thinking about.

I’m going to guess this is not a bank, but what sort of service uses this email 
authentication and why was it implemented?

Re: EC locking/shared snapshots/old data saved

[Jesse Tayler via Webobjects-dev]

Well, I don’t know but I think the fact you’d be having this problem points to 
another problem.

I don’t know your traffic or architecture, but you really should not have that 
problem at all, I wonder if perhaps you are creating too many separate ECs?

I find myself generally putting the bulk of operations into one EC and 
sometimes creating others for one-off stuff or just because it is a linear 
process with clear results.

Recently I did a lot of invalidating objects based on flags that were likely to 
require updating from a remote thread, this isn’t a conflict but I did need to 
ensure those objects were fetched and their contents written over what is in 
memory.

In that case, the user operating the session was really the only part that 
needed instant updates and only in certain circumstances.

Anyway, I’d think about the problem more broadly since I’m personally confident 
WO/Wonder has the most logical locking and EC handling that has been honed and 
crafter over decades and used in all kinds of situations.

That confidence would lead me to at least try and solve your issues in another 
way perhaps

Re: [ERRest] - Manually generating rest URL

[Jesse Tayler via Webobjects-dev]

What I think you want is a DA to return JSON, perhaps like this:


public WOResponse responseForPoint(DataPoint point) {
ERXKeyFilter filter = DataPointController.showFilter();
String json = ERXRestFormat.json().toString(point, filter);
WOResponse aResponse = new WOResponse();
aResponse.appendContentString(json);
return aResponse;
}

Re: [ERRest] - Manually generating rest URL

[Jesse Tayler via Webobjects-dev]

I might be confused

Not sure this is the right API for what you want since this API is for a 
specific page or object ID?

ra/Vote/2343.html

or

ra/User/jtayler.html

Is what I might expect

Those routes are HTML and either need default HTML or a static view page for 
that entity that accepts an object to inspect.

Are you looking to invoke a list page?

This is a list with params and basically an apache rule redirects the URL into 
the longer version and my app intercepts link URL requests and exchanges links 
on production that are shorter.

http://planaby.com/event/nearby.html?distance=30.0=40.7450127906344=-73.9771424224899

or

http://planaby.com/person/1.html

Is just a simple ERRest route url translated by apache so it looks shorter in 
production

Maybe that helps

Re: [ERRest] - Manually generating rest URL

[Jesse Tayler via Webobjects-dev]

If you want to generate an action URL, I think you’ll want this API

String link = ERXRouteUrlUtils.actionUrlForEntity(context, entityName, 
entityID, action, format, queryParameters, secure, includeSessionID);

Re: Help with Apache... stuck

[Jesse Tayler via Webobjects-dev]

Let’s see…

RewriteRule ^/signup /apps/WebObjects/WOMan.woa/wa/signup 
[last,passthrough]

I notice my configuration shows /apps/

DocumentRoot "/var/www/html/planaby"
ServerName ec.planaby.com:80
ServerAlias planaby.com
ServerAlias 10.150.65.203


Not much there…

Then I have a variety of convenience rules to redirect.

Like the rewrite above, I can hardly even read them myself…

Maybe that helps give a clue

Re: Help with Apache... stuck

[Jesse Tayler via Webobjects-dev]

You’ve tested to the ip:port directly and your app runs ok?

Then it would indeed sound like apache, since wotaskd or monitor would show 
other error types I’d think.

I think you could test wotaskd / monitor using a url with a port number like 
-2001 on the URL, but I don’t think that will reveal anything for you here.

Are you mixing html website with your app? I’m no good with apache rules 
myself, but your setup is different than what I typically do.

I’d fuss with apache first-there’s output logs listed in the config somewhere 
you might make sure there’s nothing printed there.

Re: Multiple timezones

[Jesse Tayler via Webobjects-dev]

Just to complain about how hard this can be?

Our events service let’s you post events at certain times and locations. Great.

But those locations could be outside your timezone, or that date of the event 
might pass daylight savings…

So, first — we had to identify the location, venue and lat/lon to know the 
specific location.

From there, we called a google query to turn a lat/lon and time/date into a 
timezone offset!

Then we needed the fully qualified date in GMT or the local TZ of the user but 
then you’d need to translate that time into that specific place and time — so, 
the date might cross and boundary or the location etc. etc.

We also had web pages with TZ dates and times on them which could be the first 
thing you see as a public users, so a session timezone has to be set and the 
page gets refreshed before drawing anything and then comes back down again but 
with the local timezone as reported by javascript query on the client browser.

WHEW!

What a drag!

Re: Multiple timezones

[Jesse Tayler via Webobjects-dev]

I do a lot of timezone stuff, even had serious troubles with deciding how to 
handle certain problems like not already knowing a public user’s timezone until 
basically submitting and returning a page at least once to set the session TZ 
correctly.

Even then weird things like a timezone listing in ancient UNIX used by some ISP 
in Mexico had alternate names that we had to sort of fuss with to get into 
modern zone names

So, naturally the whole thing is…complicated…sigh.

I’m happy to help impart anything I know if you need help with something 
specific

Ok, well here’s where you are having trouble

Firstly, are you sure you have the WOLipse plugin working? Eclipse should have 
a specific look, eomodeler and layout options we like to use

And I’m thinking you can install your frameworks there, but I wonder if you 
know to specifically add each ER framework and whatever else you need in 
eclipse?

Re: SQL Error on fetch

[Jesse Tayler via Webobjects-dev]

Isn’t that just when the adaptor needs to reconnect after a period of rest?

Re: REDIRECTED to non-refusing instance

[Jesse Tayler via Webobjects-dev]

Well, I don’t know the place where that log is made, but I’d guess there’s a 
TON of odd things that could cause an instance to pass on a session request 
like threads or memory

Have you got a handle on various measures of these instances you can compare to 
historical data?

Might reveal a chance in performance rather than seemingly related code.

 If there are multiple ways in which you would like to use the failsafe 
 plugin, you can always add multiple executions and put them in their own 
 build profiles 
 (https://maven.apache.org/guides/introduction/introduction-to-profiles.html
  
 ).
  Then you can fire failsafe every time you check in new code without 
 selenium and you can do something like this if your want selenium tests to 
 be run: 'mvn clean verify -P with-selenium'. There are a bunch of ways to 
 configure profiles to do something like that.

Re: Standalone D2W RuleModeler update?

I’m on Catalina?

Did I miss?

Version 1.6.0 (4)

Is what I’m running and it seems fine, but I’m not sure about bits

Re: WebObjects and Javascript Response Rewriter

[Jesse Tayler via Webobjects-dev]

I see.

Well, that’s a bit of a trick but of course, you can decide what you’d like to 
do.

I once realized that my UI elements often needed settings, defaults and 
configurations to exist in javascript — it seemed a waste and trouble to create 
new components of course, in my case, I use a lot of D2W and did not need 
programming outside the regular dev tools — but I did move the css and 
javascript additions into D2W rules, which made the component reliable and the 
programming of details often a matter of copying configurations you know work 
and writing the rule to determine when that script should be placed into the 
component.

In your case, it sounds like you might want a way they can write HTML / 
javascript components that are pulled from your app and then vended from the 
server.

Or better yet, a stub of your page with only the HTML required to jump off a 
few queries to render the rest of the page using largely website type tools 
with html segments deployed somewhere.

My sense is this would not be clean and likely won’t work out the way you’d 
really like it to, but who knows! Your situation might lend itself to some 
design choice like these and maybe that works for you.
