dyalog / miserver Goto Github PK

At Brian request I am reporting this as an issue rather than in the MiServer forum.

Having updated from MiServer 3.0 (mine was dated 16/11/2016) to 3.0.1539 I am having a lot of problems.

For a start HandleMSP on line 150 calls my function Compose, but then on line 179 call Render.
Under the old MiServer, HandleMSP called Compose only on line 170, and did not call Render at all.

Compose or Render, which should be being used?

In addition, under 3.0.1539, when attempting to read event information (when an option was selected on a drop down box),
what←_Request.GetData'_what'
selected←_Request.GetData what
"selected" is an empty string, while under the old MiServer it had the value of the item selected.
As a result, my code is failing to respond to items selected in the drop down boxes.

I am unsure if these two issues are related.

How upward compatible should MiServe be, or do I need to rewrite my (old code) every time MiServer is (or Dyalog) is updated?

If you have a folder with spaces in the path, then starting the sample MS3 site doesn't work.

When attempting to access a link that doesn't exist in a MiServer site, I get an endless wait with no response from my browser(s). I have tried this on the miserver.dyalog.com page as well as my own sites. Using the Logger extension, I see that the request is logged and that it indicates a 404 response was the correct one, but I don't see any response on the browsers that I have tried. What is going on here?

Some timeout values (e.g. HTTPCacheTime & IdleTimeout) are described as having default times of 0. But if they are removed from Server.xml the defaulting code (e.g. ConfigureServer[18-19]) blows up because it passes Dates.ParseTime a scalar '0' instead of a vector, and ParseTime can't handle a scalar.

This would probably best be fixed in Dates.ParseTime but just calling it with a vector would solve the problem.

After only a couple of minutes of looking around the MS3 sample site, my browser tabs are like this:

The only links that should open a new window are links that don't allow me to return back to the home page, E.G, PDF links or external links.

The "required" tests fail to work if the prompt of the select does not have an empty value.

start APL
)sh echo $PPID
start sample miserver application

while:
do
ps -hlp [pid from above]
sleep 2
done

repeatedly
curl "localhost:8080"
note how process grows. Eventually you'll get a WS FULL.

When querying MiServer with cURL the following is posted in to the session:
"HandleRequest" closed socket SRV00000000.CON00000000 due to error: 1001 ERR_LENGTH sending response

Our CI checks that the page works using curl before publishing anything, and this is causing the builds to fail.

To Reproduce (on linux):

• Run MiServer ( MiServer=${PWD}/MS3 dyalog ./miserver.dws )
• Run: curl http://localhost:8080

This ONLY applies to the development branch. master works fine.

On the above page, dragging fruit to the right column works, but there is always a blank item at the top which is confusing. Seems to be an issue with lm←'fruits'Add _.ListManager(fruits selected)

You need to add a path separator after line 44 of Start something like: dyalog,←('/'≠¯1↑dyalog)/'/'

"If you click on an APL expression it will be copied to the clipboard."
Just looks like plain text under "Expression"

Running MiServer with DrA on Linux I end up with a Directory named "DrA\" instead of "DrA", Crash files are then put in as a file named "DrA\xxx.dcf" (that's a filename, not a Directory/file - the \ should be /

After downloading miserver and )loading it into the interpreter, I get the following:

      )load /tmp/MiServer-3.1.1652/miserver.dws
/tmp/MiServer-3.1.1652/miserver.dws saved Wed Oct 24 06:44:13 2018

Could not load development environment due to: DOMAIN ERRORSetDelta[29] ref.SALT_Data←ref.⎕NS''
DOMAIN ERROR: Base class for Class "Page" has not been resolved

I am totally lost on what that means and how to solve it. Disclaimer: APL newbie here ;)

I am having trouble finding documentation on the supported interface for producing non-HTML MIME-types from a MiPage. Specifically, I am looking for a way to produce, say, a Text document, or something else, on certain inputs, but an HTML page on others. Is there a supported way to do this? Is this documented anywhere?

Rather than looking in a specific location for the conga workspace and if it's not there failing, we should also try ⎕cy'conga' and then fail .. something along the lines of

:Trap 0
⎕CY dyalog,'ws/conga'
:Else
:Trap 0
⎕CY'conga'
:Else
'Unable to find conga.dws'⎕SIGNAL 666
:EndTrap
:EndTrap

A couple of ideas to provide the user more information when something breaks during rendering.

1. When not in production mode (as defined by the setting of /Config/Server.xml:Production), attempt to identify the "user level" element that contains mis-rendering element. This would involve looking up the rendering hierarchy to try and identify the user element. The challenge is that many of our widgets build content under the covers...

2. When an element breaks during render, replace the content with something that would be visible on the page to indicate "this didn't render". This should be controlled by a new configuration setting.

When clicking the sample I get the following error in DrA:

VALUE ERROR
Compose[13] ac.Sections,←('p',n)New _.p(#.Files.GetText _Request.Server.Config.AppRoot,'Examples/Data/SampleText',n,'.txt')
                                       ∧

DrA file attached

I'm finding that my MiServer instance is going down roughly once a day. I'm trying to figure out what is the cause, but I'm not seeing a DrA file, though I think it might be generating an aplcore (testing again to be sure). The only thing anomalous in the Logs is a few entries that have "n" as their PeerAddr value, rather than the normal IPv6 address and port.

Is there a known standard way to debug this issue? I presume that if there were a crash or the like, that this should have been logged in the DrA system if I'm running in production mode with error trapping on?
