Re: Web aficionados - Not allow user to access file directly

[Dani Beaubien via 4D_Tech]

Hi Randy, the setup you are looking for is what I have done for all my projects.

I have two folders: “WEB_Public” and “WEB_Private”.

WEB_Public contains all my static assets like images, javascript, css, etc. 
There are no 4D tags in any of these files.

WEB_Private contains all my application specific code. When a URL comes in, if 
it is for a static file, 4D servers it directly. If it is not then the On Web 
Connection method is triggered and my application log runs. From there I can 
ensure that the session is loaded and I process the request and eventually send 
one of the files out of the WEB_Private folder.

It works very nicely and I have my static and dynamic files separated into 
different folders.

Feel free to reach out directly if you want some more information on my 
approach.

Re: [repost - desperate]What runs before ON STARTUP?

[Tom Benedict via 4D_Tech]

I don’t know whether this has been mentioned yet, but have you run MSC on the 
component? Also, it’s a long shot, but have you deleted the .4DIndy file? I 
only mention that because I’ve seen it cause strange behavior.

Difference between loading a compiled and interpreted component

Re: v15 - what code runs before On Startup?

[Chip Scheide via 4D_Tech]

This is stand alone...
I cleaned up the 4D folder in application support.

I placed a TRACE into a method which is called in every trigger in case 
a trigger was being called for some reason... no trace occurred

still getting stack space error - this occurs almost immediately after 
the 4D logo/splash screen opens.

Chip,

Component compiled (built): the alert is displayed, and the host starts normally

That is strange is it a component Cache issue?  Are you running client server

between compiled and uncompiled components that were solved by clearing the 
component cache from the server.

Re: [repost - desperate]What runs before ON STARTUP?

[Chip Scheide via 4D_Tech]

there was 1 plugin - 
I removed it from both the component and the host.
I also removed a cache folder from the host plugins folder.

Still no joy. I am still getting the out of stack space error, and 
having to force quit 4D.

This was NOT on.
I turned it on, and added TRACE and an Alert, in the component.

Component interpreted: the alert is never encountered before the Out of 
stack space issue.
Component compiled (built): the alert is displayed, and the host starts

Re: 4D v17 Property List Issues - is this only me?

I think the fastest way to a resolution would be to verify you have the same

R5. If it is not fixed, you can file a bug report directly on the forum.

Re: v15 - what code runs before On Startup?

[Douglas Cryer via 4D_Tech]

Chip,

Do you have anything in the "On Host Database Event" method in the component?

If you have the database setting on the host as: 'Execute "On Host Database 
Event" method of the components' set then any component might be running 
something.

Re: The ON STARTUP of the component is empty (no code).
As far as I know this method would not run anyway in a component.  I never use 
it so I am not sure.

Hi Kirk,

They think that we should be handling all of it.

Subject: Re: Web aficionados - Not allow user to access file directly

Hey Randy,
The optimal way to achieve this is to set up the website with a different web 
server functioning as the node publicly exposed to the internet. That server 
deals with all the authentication and heavy protection stuff 4D isn't very good 
at and communicates with your 4D server via API calls. Your 4D server can be 
locked down to only talk with something coming from a specific IP address (the 
front facing server) on a specific port.

If you can't do that the 4D server will statically serve any pages in the web 
folder with the one you identify as the index page being the default.
If you set the default page to a non-existent page, xxx.html for instance.
In this case

"The On Web Authentication Database Method is automatically called, regardless 
of the mode, when a request or processing requires the execution of a 4D 
method. It is also called when the Web server receives an invalid static URL 
(for example, if the static page requested does not exist)."
https://doc.4d.com/4Dv17R5/4D/17-R5/On-Web-Authentication-Database-Method.300-4127485.en.html


So you can intercept and validate using On web auth. If you do nothing in On 
web auth the request flows to On web connect. I generally deal with the 
requests there.

You can use the scheme of serving web pages stored elsewhere and/or construct 
the response in code. At this point you are really building and API more than a 
web server - which I think is a good thing.

If you are going to use 4D code to actually construct html pages I really 
encourage building the html as templates (stored outside the web folder).
Use Process 4D tags to populate them with data you develop in code. I find 
attempting to construct anything more than the most trivial html in 4D code the 
path to long hours and great unhappiness.

Use the so-called "Web decoy" technique. Basically you put your html files in 
another folder outside your html root. Then redirect all requests using ON WEB 
CONNECTION. For every http request 4D cannot serve directly, it uses ON WEB 
CONNECTION.

This is more elaborated e.g. here:

I don't want the web users to access html files directly, without going through 
ON WEB CONNECTION.

e.g.

http://myweb/foobar.html

If "foobar.html" exists in the web folder, Users can put in this in the address 
and it will pull up the web page, but will not process the 4D Tags, etc.
Very, very funky.

So, I'm probably being a dope, but does anyone know what I can do to prevent 
accessing html files directly?

Gracious thanks

Randy Engle

4D v17 Property List Issues - is this only me?

[Daniel Solenthaler via 4D_Tech]

Hi everyone,

Working in Design mode on a form, I find the following behaviour of 4D v17 a 
nuisance:

In 4D v16 I can click onto a cell of the property list and the cell content is 
immediately highlighted and modifiable.

In 4D v17R5 I click onto a cell of the property list and nothing happens. It 
takes 3 seconds and a „slow double click“ to highlight the cell content.

Is it only me, or does anyone else have this problem? Anything that can be done 
about it?

Using macOS 10.13.6.

Thanks,

Daniel

More info:
I created a new empty database, I added the interpreted component

The new database opens...

Re: [repost - desperate]What runs before ON STARTUP?

[Chip Scheide via 4D_Tech]

Thanks John,
no luck.

This was disabled, and there was no code in the component.
I enabled, and inserted 2 lines of code in the component in the 
database method:
Trace
alert("On Before Host Startup")

neither of these executed, and I still get a stack space error...

- I have repaired, and compacted the component, 
- checked (repeatedly) that there is no self referential calls in the 
startup routines of neither host nor component.
- checked (repeatedly) that there is not self referencing 
link/alias/shortcut, or copy of the component in the component's 
package -- anywhere.
- inserted an On Err Call method which writes to a log file, as the 
(new) first line of the host On Startup -- nothing written
- commented out all code in On Startup -- no difference
- repaired the structure of the host

I rebuilt the component (saving the previous build) and used it to 
start the host. The host starts, and I get the Alert telling me that 
the On before Host startup is/has run.

I am at a loss.

Chip

More Errors With RECEIVE BUFFER In v17

[Cannon Smith via 4D_Tech]

I’m wondering if anyone else has noticed an uptick in errors when using the 
RECEIVE BUFFER command to read from a serial port? Our application does a lot 
of serial port communication. We also log all errors. There has been a 
_significant_ uptick in errors that occur on the following line of code since 
we moved to v17:

RECEIVE BUFFER($tBuffer)

The error number reported is always -1. But if I look in the extra information 
the error is always one of these:

Error #: 995
Resource: WI32
Message: The I/O operation has been aborted because of either a thread exit or 
an application request.

Error #: 22
Resource: WI32
Message: The device does not recognize the command.

Users simply reconnect to the port and all is fine for awhile

Anyone know what might be going on?

Thanks.

On Host Database Event database method? See the Security tab in the database 
settings to disable it.

[Maurice Inzirillo - AJAR via 4D_Tech]

Hi Chip,

You can try to put in place an ON ERROR CALL and logs the errors on your 
component. Did you already try this ?

[repost - desperate]What runs before ON STARTUP?

[Chip Scheide via 4D_Tech]

I have a component which I am trying to debug. The host is interpreted, 
stand alone.

When the component is compiled and built the host starts, but of course 
I can not trace the code in the component - from which I am getting an 
error message.

When I swap in the interpreted version of the component, during 
database startup I get an error not enough memory (obviously stuck in a 
loop). 

However, currently the very first line of code in the host ON STARTUP 
is TRACE.
The not enough memory error is presented BEFORE the trace is hit.

The ON STARTUP of the component is empty (no code).

What code could be running?

Thanks
Chip
