Re: "Search References" Behavior Change
What version of 4D are you using? I don't recall seeing this problem in version 18. I just tested 19 and 19R2 - "Search References" only shows the method calls (same as "Search Callers" if the method is open).

In version 17 through 18R3 I have seen an intermittent bug where Locked returns true but LOCKED BY indicates there is no lock. Only one process uses the record, so it should not be locked.

form radio buttons broken in project mode
I just noticed that form radio buttons are no longer handled automatically when converting to version 18 project mode. For example, with radio button variables r1, r2, r3, the other two radio buttons are unselected when any one is clicked on. In version 18 project mode, they all stay highlighted. If this was a documented change, I missed it. Fortunately I don't have too many forms to fix, but something else to consider in upgrading to project mode.

Re: Object notation replacement for use of Self in a script — v18
Here is an idea which seems to work, but needs more evaluation. What if you named the form object with the property path in the form data? Even if periods are not allowed (they seem to be), another character could be used. I think the maximum length of an object name is 255 characters which should be plenty. Here is an example. I created a form with one in input and the object method below. The form object name is "some.property.path" and the expression is Form.some.property.path. Case of : (Form event code=On Load) Form.some:=New object Form.some.property:=New object Form.some.property.path:="TEST 123" : (Form event code=On Data Change) C_TEXT($name) C_COLLECTION($cPath) C_OBJECT($object) $name:=OBJECT Get name(Object current) $cPath:=Split string($name;".") $object:=Form For each ($name;$cPath.slice(0;-1)) //All except last element to get the object. $object:=$object[$name] End for each $name:=$cPath.pop() $object[$name]:=Uppercase($object[$name]) End case John DeSoi, Ph.D. > On Apr 30, 2020, at 7:53 PM, Peter Hay via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > What we really need is a way to access a Form Object's "Variable or > Expression".

Re: 4D Server v18.1LTS - Startup Takes 10-15 Minutes
Sorry if I missed it, but I still did not see in your messages that you reproduced the slow startup with conversion on a separate non-VM machine. Also wondering if there is any difference between 4D single user and 4D Server. I have not used 4D Server to convert structures to project mode. I regularly convert a 17.4 binary structure to 18 project mode for version control. It has over 5000 methods and many hundreds of forms. It only takes a few seconds to export to project mode (using 4D single user). A work-around might be to covert to project mode before moving the structure to the VM server.

Re: 4D Server v18.1LTS - Startup Takes 10-15 Minutes
Have you tried it using binary mode to see if there is any difference? Is there anything unusual about your project, e.g. a really large number of methods or forms? You get the same results on different computers? Is it a regular server or a merged server application? I assume your application is compiled; if so, have you tried to open it with 4D server interpreted?

Re: Display entity selection time fields in a list box?
No, that is a compatibility setting for older 4D versions where time values were converted to milliseconds instead of seconds.

Re: Worker and UI
I don't see why it would not work. I'm not aware of any real difference between a worker and a regular 4D process except that a worker has queue of requests and lives until killed whereas a regular process executes one request and exists. I tend to use the 4D progress component with some wrappers that allow it to be used by any process or worker including hidden and preemptive. It can also monitor and cancel jobs executing on the server. A lot of work to set up, but usable for almost anything once it is in place.

Display entity selection time fields in a list box?
I'm replacing some record based list boxes with entity selection list boxes. I want to see HH MM SS format which was easy and the default with selection list boxes. But since ORDA treats time as a number, the only way I see to do that is to wrap the field property path with the Time function, e.g. Time(This.time_field). Without that, any time format set with OBJECT SET FORMAT just displays the number of seconds. Is this really the only way to display time fields or have I missed something? Seems like a step backwards. I'm using 18.1 Mac.

Re: gitignore for projects
I ignore anything in the settings directory, but you could argue against that. For example, you might want to track changes in your build settings file. You can't ignore catalog.4DCatalog if you want to track table and field changes to your structure. I'm currently exporting structure changes in 4D 17 to a 4D 18 project mode branch in catalog.4DCatalog. One frustration is that just opening in 4D 18 project mode shows changes in catalog.4DCatalog without doing anything. I reported this as a bug, but it is apparently not reproducible by anyone else.

Re: [off-ish] v17 or 18 - Exported forms
Yes, forms are exported in JSON format. In project mode, CSS files are used for some of the style information.

Re: atom/st indent/lex file
I'm working on something for TextMate and/or BBEdit. I'll post it, hopefully in the next week or two. Note 4D is a lot more difficult to syntax color than other languages because you can't disambiguate many tokens without the structure file information. Having "code with tokens" helps somewhat, but is harder to read. Even with tokens, you have things like $value:=Some_Token. Some_Token could be a process variable, method call, or component call. No way to know without the 4D structure information. I don't know what "ST" is.

Re: Printing Excel Document to PDF from 4D - Windows
The best PDF generation I have found is using Chrome headless via Puppeteer (https://developers.google.com/web/tools/puppeteer). For most reports, I generate a single source document in HTML that works with web browsers, Excel, and PDF. Since you are already generating Excel documents, perhaps Excel -> HTML -> Puppeteer/PDF might be an option. I guess it all depends on Excel automation options. I have not done much on that end other than asking Excel to open HTML documents. Side note: 4D 18 includes some nice Zip commands. If you are willing to slog through a lot of details, 4D 18 can create Excel files using the XML and Zip commands without any plugins.

SCAN INDEX broken 18.0 client/server?
Just started 18.0 client/server testing and was hoping to deploy sooner rather than later. But SCAN INDEX seems to be broken returning zero records in client/server mode. The other thing I'm not seeing is what I need to do with the users and groups directory.json for built client/server applications. It works with 4D Server from the default location but not a built server (my default user is missing). Does it have to be copied somewhere during the build process? Anyone care to share their experience with 18.0 deployments? I'm especially interested in client/server developed with project (source) mode.

Re: Dates and 4 digit years.
Does your query look like this QUERY([Table];[Table]Date_Field<=!1919-12-31!) or this QUERY([Table];[Table]Date_Field<="12/31/19") Using a string can cause issues with date interpretation.

I don't see how the pivot year could have anything to do with it - that just controls data entry when two digit years are entered. I don't have 17R5, but I don't see any problems with 17.3 or 18.0.

Re: problems with SSL cert/SOLVED
Glad to hear you solved it. The initial setup can be a bit complex, but I highly recommend automating the whole SSL certificate thing with Let's Encrypt. The certificate cost goes to zero and you never have to worry about it again unless your logging script says you have an issue. It automatically renews every few months and I have seen zero issues since setting it up about a year and a half ago. There is a 4D tech note about it in the link below.

Compare the file permissions on the old key to the new key and make sure they are the same. Not sure about Windows, but with Linux things sometimes fail if file access is too permissive.

Re: HTTP Upload file size too low
This is what I was trying to get at a few messages ago. Maybe WEB GET BODY PART does support chunked encoding, but that is irrelevant if the client side does not support it. As best I can tell from Jim's description is he is using a standard HTML multipart form with a file input. Javascript is not involved, so having this work depends on the browser's support for switching to chunked encoding. I don't know if web browsers directly support it or if there is some magic you can add to the form to request it. If not, there seem to be plenty of Javascript libraries that can do it. So then the task becomes redoing the form with the Javascript library instead of relying on the standard HTML form implementation. I found this Javascript example, which looks simple to implement. https://gist.github.com/shiawuen/1534477 John DeSoi, Ph.D. > On Jan 9, 2020, at 3:38 AM, Epperlein, Lutz (agendo) via 4D_Tech > <4d_tech@lists.4d.com> wrote: > > I'm not sure if I understand your environment in which you would do that file > upload.

The client and the server have to agree on sending with the chunked protocol. This is obviously not supported by WEB GET BODY PART. That means you would have to code the transfer yourself using WEB GET HTTP BODY (using chunked encoding) and then you will have to parse the multi-part form yourself because you can't use WEB GET BODY PART. I did something like this aeons ago using ITK before 4D's web server was implemented. Even if I could find the code, I don't think it would be much help.

Re: gitignore for projects
Hi Jeremy, One I used to use (GitX, I think) would sometimes take forever or spin the beach ball of death for large commits. I'm now using Fork (which I really like). Sometimes I get various commit or other operation errors. No problems from the command line. Here is another issue to watch out for with 4D/Git. In 4D you can globally rename a method changing only the case and not the spelling. Even if 4D changes the method name on disk, git remembers the case of first commit. It is not seen as a change because by default on Mac and Windows file names are not case sensitive. So if you switch branches, git checks out the file name using whatever case you used initially. This cases 4D to tokenize the name incorrectly in method callers. To solve this, you need to use git mv to tell git to use to updated name case when you rename methods without changing the spelling.

Yes, there are a number of differences not only between 17.3 and 18 project mode, but between 18.4db and 18 project mode. For example, the picture library does not exist in project mode. Method comments are gone in project mode. I minimally use users/groups, but that is different also.

Roughly 150,000 lines of source code and probably about 300 or so forms. A lot has happened between 17r5 and 18, so it might be worth trying again.

Conceptually, that is the best way to think about it. After the first conversion you have a "master" branch which is the 4D 17 version converted to 18. Initially, the "18" branch is exactly the same. Then I can switch to the 18 branch and work on new features that use new commands and functions added in 4D 18. >> >> When I want to commit a new version I have a 4D method that copies the >> structure, opens it in 4D 18, and then exports the structure in project mode >> format. > > Are you doing this workflow to continue development in v17? Yes. Switch back to the 17 "master" branch. Verify there are no uncommitted changes in the Project folder (git status called from 4D). Move the Project folder to the trash. Run the 17 to 18 script again and generate a new Project folder with the current source. Commit as the new "master" branch. Merge (or fast forward) the master branch into the 18 branch to keep it up to date with the changes in 4D 17. In this model, I'm only making structure and form changes in the 17 master branch. Methods can be changed in both branches.

Re: gitignore for projects
You can keep your project in binary mode (even keep it in version 17) and still take advantage of version 18, project mode, and git. Here is what I'm doing. "Master" branch is version 17. When I want to commit a new version I have a 4D method that copies the structure, opens it in 4D 18, and then exports the structure in project mode format. This can be completely automated and only takes a few seconds. Now that you have a master branch, you can create a version 18 branch for implementing next version features that take advantage of new 4D 18 capabilities. Just open your source directly in version 18 project mode. You can test the conversion and have both 17 and 18 versions open at the same time as long as you have separate data files. You can continue to make version 17 changes, export, and then merge into your 18 branch. At some point in the future, all your conversion issues will be resolved and you can promote the 18 branch as master and deploy with 4D 18.

Re: Object from row in selection listbox
By "selection based listbox" I assume you mean traditional record selection
listbox and not an entity selection/collection listbox. I have not tested this,
but I think it will work without changing the highlighted records or scroll
position.
COPY SET("UserSet";"MySet")
CUT NAMED SELECTION([Table];"CurrentSelection")
USE SET("MySet")
$entitySelection:=Create entity selection([Table])
USE NAMED SELECTION("CurrentSelection")
COPY SET("MySet";"UserSet")
Since it is not possible to pass an entity selection from one process to
another, it would be really nice if 4D provided direct commands to convert sets
and named selections into entity selections.

I'm pretty sure that it is. It looks like this; You might also look at the private key.

You can't determine the type of the array. I think you can load any type into a text array, but then you would have to convert it.

If so, I suspect the error is happening in the "additional request". If you provide that, then HTTP Get should return the right HTTP error code. Hopefully you know ahead of time what method to use and this is better because you omit the extra request and should get any error code directly from the site.

Re: Silent Failure when Constructing an Object
Yes, for a certain class of errors, 4D sends a HTTP 500 error response and a HTML body with the error information. You should try your test locally to verify. Of course, you should have a error handler and be able to capture any error and log it if you are using the HTTP server. Unfortunately, there are several types of pointer errors that 4D's error handler won't capture even if you have an error handler. Instead 4D shows a dialog with "Continue" and "Abort" buttons on the web server or to the end user if not a web process. I'm not sure which is worse. But with the web server, the process is stuck until someone comes along and presses the button.

Re: Prevent Client from Sleeping
On the Mac you can use "caffeinate" via LEP. NAME caffeinate -- prevent the system from sleeping on behalf of a utility SYNOPSIS caffeinate [-disu] [-t timeout] [-w pid] [utility arguments...] DESCRIPTION caffeinate creates assertions to alter system sleep behavior. If no assertion flags are specified, caffeinate creates an assertion to prevent idle sleep. If a utility is specified, caffeinate creates the assertions on the utility's behalf, and those assertions will persist for the duration of the utility's execution. Otherwise, caffeinate creates the assertions directly, and those assertions will persist until caffeinate exits. Available options: -d Create an assertion to prevent the display from sleeping. -i Create an assertion to prevent the system from idle sleeping. -m Create an assertion to prevent the disk from idle sleeping. -s Create an assertion to prevent the system from sleeping. This assertion is valid only when system is running on AC power. -u Create an assertion to declare that user is active. If the display is off, this option turns the display on and prevents the display from going into idle sleep. If a timeout is not specified with '-t' option, then this assertion is taken with a default of 5 second timeout. -t Specifies the timeout value in seconds for which this assertion has to be valid. The assertion is dropped after the specified timeout. Timeout value is not used when an utility is invoked with this command. -w Waits for the process with the specified pid to exit. Once the the process exits, the assertion is also released. This option is ignored when used with utility option.

Re: The set does not exist
There is the answer: "the data source is arrays". The highlight set only applies to selection (table) based list boxes. To get the highlighted rows of an array listbox, you use the True/False value of the boolean array representing the listbox.

Re: 4D 17.1 network issues
I set the WiFi to "Inactive" using the small popup at the bottom of the list and rebooted the computer. That removed it from the ifconfig list and the server no longer shows the self assigned IP. I suspect the 4D 17 networking issues are related to computer sleep and/or the new network layer implementation of putting connections to sleep on the server after an inactivity timeout (the default is 20 seconds). I tested two changes over the past week: - Prevent the computer from sleeping when 4D Client is running. - Disable the connection inactivity timeout - SET DATABASE PARAMETER(Idle connections timeout;0). The logs showed only one client session that was aborted. I also ran a client test for over a week that implemented delays on both the client and server side ranging from a minute to 2 hours. No issues. I had previously tried setting Idle connections timeout to 5 minutes. That did not help, there were still aborted connections. If this is not a 4D Server problem, I'm not sure what else could be done to fix it. There were no issues like this with 4D 16.4. This is a single switch network, no routers are involved. The switch is about 6 months old and has no configurable settings.

Maybe all you need is to uncheck this. I switched to 64 bit only with version 16, so only the new network layer is in use. I received a response off-line that stated similar problems and the issues were solved by upgrading to 17R3 or later. I hope there is a better solution.

4D 17.1 network issues
Since I upgraded from 16.4 to 17.1 (all Mac), users have been complaining about 4D Client disconnects. Messages like: "The current connection to the database has been disrupted. Connection error with the server. Please restart the application." "Unknown Error. Connection error with the server. Please restart the application." It is an all local single switch network with default timeouts. I experimented with changing timeouts, but it did not help. The server hardware also changed (new 2018 Mac Mini), so I'm looking into that. One curious thing I noticed is the "Application Server" tab shows it to be listening on two IP addresses: 192.168.X.X and 169.254.X.X. The 192 address is expected and the only active network connection on the computer. Why would the server be listening on a 169 link-local address and where did that come from? I don't see that when I run the server on my laptop under the same operating system (10.14 Mojave). Digging into it with Wireshark is next, but hoping someone might suggest an easier path.
