History

#2 Updated by Greg Shah about 3 years ago

Implement a variant of P2J-OPEN-URL (see #1815) called OPEN-MIME-RESOURCE. The idea is that where P2J-OPEN-URL is meant to allow the user's browser to load the URL directly, the OPEN-MIME-RESOURCE is meant to load a mime resource (text file, PDF, CSV, XLS, even html... that exists on the FWD client) down into the user's browser. If that resource can be rendered by the browser, we would want it to load in its own tab. As a fallback, any resource that cannot be rendered by the browser should prompt the user for download/open via helper app.

Please see #1795-61 (and later) for more details on the features needed. This should be used for both OUTPUT TO PRINTER as well as for the enhanced browse export feature.

Created 3474a for this task.

#5 Updated by Sergey Ivanovskiy about 3 years ago

Please clarify that OPEN-MIME-RESOURCE should be used in OUTPUT TO PRINTER statement as well as for the enhanced browse export feature. What does it mean?

This js framework http://mozilla.github.io/pdf.js/getting_started/ can be used by Swing and Web clients both to render pdf documents in browsers.

Also this java library http://cssbox.sourceforge.net/pdf2dom/ can be evaluated. It transforms pdf documents into html documents.

#6 Updated by Greg Shah about 3 years ago

There are many ways for converted 4GL code to generate some kind of output. Once that output is created, it needs to be provided to the end user in some way. In the original 4GL system, the output was already on the end user's desktop system. File resources were on the hard drive, other things might be directly output to printers, email or devices (including the screen).

In the web client the user is assumed to be running the browser on a different system than where the FWD client is executing. Although the local web client is possible, we cannot assume it is in use. Since the user has no direct access to the output, we must provide a facility for the output to be opened via the browser so that the user can view, interact, save and print any such output.

The idea of OPEN-MIME-RESOURCE is to provide a tool to do this which can be used in 4GL converted code (but only in FWD since there is no OpenEdge version). This is an enhancement of the 4GL syntax itself.

OUTPUT TO PRINTER sends the PDF down to the browser. It appears as a "download or open with" prompt. Just like with any other output that is generated by the FWD client, the PDF needs to get down to the user's browser BUT we don't want it to always prompt for the user to open or download it. We really want it to be loaded as a tab in the user's browser with no other interaction needed. This is the same thing we are already doing for OPEN-MIME-RESOURCE, so I don't want to duplicate work. The same solution for OPEN-MIME-RESOURCE should be used "under the covers" in OUTPUT TO PRINTER.

This js framework http://mozilla.github.io/pdf.js/getting_started/ can be used by Swing and Web clients both to render pdf documents in browsers.

The license is Apache 2, so it is OK. I'm open to this idea. Can you please describe how you envision this to be implemented?

Does this only work for PDF mime types? We must support a range of mime types (text, xls, pdf...). I was thinking we would use the browser's built-in support for mime types rather than build our own custom viewer for each one.

On the other hand, PDF will be a very common one and could be worth a custom implementation if we get a really good result (as compared with using the browser directly).

Also this java library http://cssbox.sourceforge.net/pdf2dom/ can be evaluated. It transforms pdf documents into html documents.

No, this won't work for our needs. The user must have the original file and be provided to the user so they can save it or interact with it using some native tool (e.g. xls file in Excel as the browser's application helper).

#7 Updated by Sergey Ivanovskiy about 3 years ago

Found that pdf.js supports only these browsers https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#what-browsers-are-supported It is reported that Safari and IE11/Edge have limited supports(?).
If it is fitted our case, then we can create the dedicated mime type servlet handler that sends html output rendered in a web page. Although the viewer web page design can be the issue, pdf.js provides this example for evaluations http://jsfiddle.net/pdfjs/wagvs9Lf/?utm_source=website&utm_medium=embed&utm_campaign=wagvs9Lf

#8 Updated by Sergey Ivanovskiy about 3 years ago

It seems that a servlet that implements OPEN-MIME-RESOURCE should only send a document with its correct mime type, then the target browser can display the target document if its document type is supported by this browser.

Note that using the embed HTML 5 tag can increase the chance for the browser to open the document in a new window/tab. This worked OK for Chrome, even when it was configured not to open pdf files in a tab.

#10 Updated by Sergey Ivanovskiy about 3 years ago

OK. I will try embed. What are operands of this OPEN-MIME-RESOURCE? Is it the same as for P2J-OPEN-URL?

#11 Updated by Greg Shah about 3 years ago

What are operands of this OPEN-MIME-RESOURCE? Is it the same as for P2J-OPEN-URL?

It is not the same.

1. MIME type as a string/character value (e.g. "text/plain").
2. Some way to reference the resource, usually a filename for the FWD client system is one example. I'm not sure what is needed for usage from OUTPUT TO PRINTER.

#12 Updated by Sergey Ivanovskiy about 3 years ago

Thank you. I will follow this design.

Working on OPEN-MIME-RESOURCE. According to P2J-OPEN-URL

/**
 * Matches the P2J-extension language statement P2J-OPEN-URL and a mandatory
 * following character expression.
*/
p2j_open_url_stmt
:
KW_OPEN_URL^ expr DOT!
;

the target statement requires to define a pair of strings or to define 2-tuple in order to state something like
open_mime_rsrc_stmt
   :
      KW_OPEN_MIME_RESOURCE^ pair DOT!
   ;

#15 Updated by Sergey Ivanovskiy about 3 years ago

Actually, there is a helpful example how to state 2 or 3 parameters

/**   
 * Matches the COLLATE keyword and the required following
 * 2 or 3 character expressions.  The tree is rooted on the 
 * COLLATE keyword and all parenthesis and commas are
 * dropped from the tree.  The resulting tree will have 2 or 3 children,
 * each an expression.
 * <p>
 * Used by {@link #preselect_phrase} and the subtree is rooted by the
 * keyword (which is the reason for using a separate rule for something so
 * simple).
*/
collate_clause
:
KW_COLLATE^ LPARENS! expr COMMA! expr (COMMA! expr)? RPARENS!
(KW_DESCEND)?
;

#16 Updated by Sergey Ivanovskiy about 3 years ago

Finally, this construction works properly

/**
 * Matches the FWD-extension language statement OPEN-MIME-RESOURCE and a mandatory
 * pair of resource mime type character and its url character expression.
*/
open_mime_resource_stmt
:
KW_OPEN_MIME_RESOURCE^ expr expr DOT!
;

#17 Updated by Sergey Ivanovskiy about 3 years ago

Working on OpenMimeResourceHandler that should handle print requests from js web clients by loading html document with the embedded content to the target resource, then PDFPrintOutputHandler loads this document to the browser.
It seems that if we consider the case when java web clients are under proxy server, then the following code shouldn't work

         case types.MSG_OPEN_PRINT_OUTPUT:
            var offset = 1;
            var textLength = message[offset];
            offset = offset + 1;

            var id  = me.readStringBinaryMessageByLength(message, offset, textLength);
            offset = offset + textLength * 2;

            window.open("/print/" + id, "_blank");
            break;

because JS clients are out of the proxy server network. According to our web client design we have webRoot path as a root for all available web resources.

Btw. why don't we reference the resources relative to the index file?

So instead of
<script type="text/javascript" src="${webRoot}/common/p2j.js"></script>
having this
<script type="text/javascript" src="common/p2j.js"></script>.

#19 Updated by Sergey Ivanovskiy about 3 years ago

Yes, it seems we can use relative path if there are no missed design features.
It seems that web socket requires absolute path in this template index.html

'url' : 'wss://' + window.location.host + '${webRoot}/ajax',

#22 Updated by Sergey Ivanovskiy about 3 years ago

It seems the idea applied in PDFPrintOutputHandler to use direct output on document.save(output) should not work because it should close output stream before the actual data was written into https channel.

Which output stream do you mean to be closed?

Btw. I think there is a bug in GUIPrinterStreamSupport.closeStream(). The document should be only closed from the finalizer, and not from the consumer.

#24 Updated by Sergey Ivanovskiy about 3 years ago

I mean https output stream. For an example, this code works properly

         ByteArrayOutputStream bout = new ByteArrayOutputStream();

         output.outputConsumer.accept(bout);

         ServletOutputStream out = httpServletResponse.getOutputStream();

         out.write(bout.toByteArray());
         out.flush();

The next finding is that embed tag in my environment doesn't help to display the target pdf. I can watch its content if looking at the source document. view-source:https://localhost:7449/print/8fd81ccd-2f4c-4668-8097-c79a3b510a06. I think we should send pdf output without wrapping it in html template.

#25 Updated by Sergey Ivanovskiy about 3 years ago

In my test the requested wrapped document has this url https://localhost:7449/open/resource/?path=8fd81ccd-2f4c-4668-8097-c79a3b510a06&mimeType=application/pdf and the target document has this https://localhost:7449/print/8fd81ccd-2f4c-4668-8097-c79a3b510a06. I got this document

<body>
<embed src="/print/8fd81ccd-2f4c-4668-8097-c79a3b510a06" type="application/pdf"/>

and got /print/8fd81ccd-2f4c-4668-8097-c79a3b510a06 but Firefox didn't show its look and feel.

The problem is that PdfBox closes the provided stream when PDDocument.save() is called. Instead of creating new memory-backed stream, just create a simple stream wrapper that will provide a no-op override for its close() method and use it in GUIPrinterStreamSupport.closeStream(). GuiDriver.deliverPrintOutput() states "The consumer implementation must not close the provided stream.", so this change should satisfy the requirement.

#27 Updated by Sergey Ivanovskiy about 3 years ago

Yes, agree. About embed tag I can test this http://mozilla.github.io/pdf.js/getting_started/ with our own view pdf template open-resource.html if there are no objections.

Check the network monitor in the browser on the pdf resource (/print/...), what HTTP status code do you get in the response? Also do you see any errors in PDFPrintOutputHandler?

There are no exceptions and pdf document is on the client but it isn't displayed by Firefox. May be it is a template issue (open-resource.html). Please review committed revision 11246 with PDFPrintOutputHandler changes.

#30 Updated by Sergey Ivanovskiy about 3 years ago

Another questions follow. We have ReportOutputFormat and GuiDriver.this.deliverPrintOutput(Consumer<OutputStream> consumer, Runnable finalizer, ReportOutputFormat format) and reports of this type ReportOutputFormat.PDF are handled by PDFPrintOutputHandler. Are there handlers for CSV, XLS, XLSX reports? How to test these document types?

ReportOutputFormat, GuiDriver.deliverPrintOutput() and related were created to support delivery of print outputs to clients. They were created before I was aware of OPEN-MIME-RESOURCE.

But I think these can be generalized easily. Rename deliverPrintOutput to something like deliverMediaResource, PDFPrintOutputHandler to MediaResourceHandler and so on. Also ReportOutputFormat is probably redundant, it can be replaced with com.google.common.net.MediaType.

#33 Updated by Sergey Ivanovskiy about 3 years ago

Yes, it works for me too. The problem was "Content-disposition" value: attachment or inline. If attachment is specified in header "Content-disposition", then nothing is displayed and the content isn't downloaded.

Please review committed revision 11248. Now this construction is supported by web clients.

open-mime-resource string("application/pdf") string("file:/home/sbi/Documents/groups.pdf").

I didn't implement it for Swing clients.

#39 Updated by Greg Shah about 3 years ago

I didn't implement it for Swing clients.

It would be useful to launch a browser (we already support that) and then load the same way as in the web client.

Otherwise we have no solution for the Swing case, in printing or anything else like this.

#40 Updated by Sergey Ivanovskiy about 3 years ago

It needs to reuse the code that is responsible to fill html templates HtmlResourceHandler. Otherwise these functionality will be duplicated.

#41 Updated by Sergey Ivanovskiy about 3 years ago

The implemented method to wrap documents with help of open-resource.html template (embed) doesn't work for binary content types represented by application/octet-stream. It seems that in this case it is needed to request the target document directly from its handler.

Does this allow you to have something like open-mine-resource "text/plain" "a.txt". or is it always needed to have string("text/plain")?

I checked that plain string parameters can be used too. Committed rev 11252 added missed java docs.

Embedding the media (using embed tag for example) relies on the browser (or an installed plugin) being capable to handle it. Some media types can be embedded, some not. We should probably make this configurable. Greg, what do you think?

#46 Updated by Greg Shah about 3 years ago

We should probably make this configurable. Greg, what do you think?

Yes, this makes sense. We can embed by default and allow an optional boolean 3rd parameter (true means embed, false means don't embed).

#47 Updated by Sergey Ivanovskiy about 3 years ago

OK, planning to add this optional parameter. Committed revision 11254 changed SwingGuiDriver.this.deliverPrintOutput to open printed documents via SwingGuiDriver.this.openURL. I found that SwingGuiDriver.this.deliverPrintOutput is possibly changed in the future

      // this implementation is not expected to be deployed in production due to possible file name collisions

Currently all the url targets are first copied to the machine that runs the FWD client and then streamed to the end-user's browser. This holds true even for urls that are not local to the FWD client system. Do we really want this? Or do we want to directly open the global urls in the user's browser (i.e. http://example.com/example.pdf)?

Currently all the url targets are first copied to the machine that runs the FWD client and then streamed to the end-user's browser.

Or do we want to directly open the global urls in the user's browser (i.e. http://example.com/example.pdf)?

No, only ids are copied.

In GuiWebDriver.openMimeResource() method body:

   public void openMimeResource(String mimeType, String path, boolean embedded)
   throws MalformedURLException
   {
      final URL url = new URL(path);

When you supply an absolute URL with a domain, the openStream() and the ByteStreams.copy() calls will effectively fetch the target resource to FWD client.

Now I understand your question. Yes, now it is possible to load documents by their URLs. it depends on requirements for OPEN-MIME-RESOURCE.

#55 Updated by Greg Shah about 3 years ago

Yes, now it is possible to load documents by their URLs. it depends on requirements for OPEN-MIME-RESOURCE.

I should have specified this.

Only resources that are already on the FWD systems should be streamed. Any directly accessible URLS should be sent only as a URL, without copying to the FWD client.

#56 Updated by Greg Shah about 3 years ago

Please remove this comment and code:

      // this implementation is not expected to be deployed in production due to possible file name collisions
      // in multi-user environments and unresolved security concerns

      UnimplementedFeature.experimental("Swing GUI PDF print output is an experimental feature not meant " +
                                        "to be used in production environments.");

At this time, I don't think we need to treat this as experimental.

The same issues exist for both Swing and Web clients. Actually, the Swing client is more likely to be run on a single client system, reducing the possible security issues. The primary problem is that we do no checking of the URL and this certainly exposes the user to some level of danger depending on how the URL is obtained.

Regardless, I don't want to suggest in the code that the feature doesn't work or cannot be relied upon.

#57 Updated by Sergey Ivanovskiy about 3 years ago

Greg, please clarify this case. There are server's resources and client's resources. Should P2j-OPEN-URL url. satisfy the same requirement that resources are loaded only if they are on the FWD system?

#58 Updated by Greg Shah about 3 years ago

There are server's resources and client's resources.

As far as I know, at this point all the resources we need to stream are already on the FWD client. Those resources would be accessed via a file:// URL.

Does anyone know of a case where we need to load from the FWD server?

Any URL that addresses a resource located outside of the FWD client, should still be sent to the client but it will not be streamed from the FWD client. Instead, the browser can load that resource directly from the URL.

#59 Updated by Sergey Ivanovskiy about 3 years ago

We don't specify the case if this command is failed. What should be done in this case? Now if resources are failed to load or specified urls are malformed, then exceptions on the client side are thrown. If resources are external, then only urls will be sent to the client side. Does it need to have a feedback in this case?

Code Review Task Branch 3474a Revision 11256

This is really good. I think it is almost finished.

1. Please change kw_open_mime_resource to be kw_openmime. We always limit the KW_* constants to a maximum length of 11 characters including the KW_ prefix.

2. On the new Keyword("open-mime-resource"... line, please add a comment // FWD extension, not real 4GL!.

3. Please change the keyword text for "p2j-open-url" to "open-url". It is more consistent with our current approach which does not use a p2j-/fwd- prefix.

4. Do we need to have both MSG_OPEN_PRINT_OUTPUT and MSG_OPEN_MIME_RESOURCE messages? Doesn't MSG_OPEN_MIME_RESOURCE handle both needs?

5. It seems that our MSG_OPEN_PRINT_OUTPUT and MSG_OPEN_MIME_RESOURCE message is limited to 255 bytes in size and the URL is also limited to 255 characters (if the entire URL could be fit). I say this because it seems that the size of the message and URL are both limited to a number tat can be fit into a single byte. This seems to be too small and it also might be a kind of buffer overflow problem if the input is larger.

6. Please check if we have other web socket cases where our strings are limited to 255 characters without any checking of actual lengths.

7. PDFPrintOutput is not always a PDF, right? Shouldn't we name this class differently to be more clear?

8. Is TC.openMimeResource() a superset of TC.openURL()? It seems like the server side can just call TC.openMimeResource() with the right parameters to get the same result.

9. For SwingGuiDriver.openMimeResource() can't we honor the mimeType and embedded parameters?

10. build.xml, PDFPrintOutput, GUIPrinterStreamSupport are missing history entries.

Yes, it seems that MSG_OPEN_URL can be delegated to MSG_OPEN_MIME_RESOURCE too.

Yes, the id field in MSG_OPEN_PRINT_OUTPUT holds UUID and has 16 byte length, but MSG_OPEN_MIME_RESOURCE can hold URL and the mime type field can be a long string. I missed all these facts.

8. Is TC.openMimeResource() a superset of TC.openURL()? It seems like the server side can just call TC.openMimeResource() with the right parameters to get the same result.

Yes.

9. For SwingGuiDriver.openMimeResource() can't we honor the mimeType and embedded parameters?

I didn't implement a special code because this command should open a browser with a file resource. It seems that the embedded value, false or true, doesn't have an affect on this case. And the mimeType value looks unimportant in this case.

I don't understand this part. If we have generated a PDF and are displaying it, the user will want the PDF to appear as a browser tab in the browser launched for the Swing client, just as they would see in the web client. The only difference between these cases is the fact that we must launch a browser in the Swing case. Otherwise, it should act the same.

open-resource.html:
"https://" + window.location.host + "${webRoot}/${documentHandler}/${documentPath}";
The expression misses location.port.

lang_stmts.rules
OPEN_MIME-RESOURCE -> OPEN-MIME-RESOURCE

Why do we need both keywords OPEN-MIME-RESOURCE and OPEN-URL? Is there any use case that OPEN-URL couldn't
handle? A file local to FWD client can be expressed with a url such as file:///path/filename.

The doc for the method openMimeResource in several classes mentions path as the second param. But this can
be a full URL according to all the implementations. Please rename the parameter and fix the documentation for
it.

GuiWebDriver.openMimeResource()
The opened input stream should be closed in a finalizer. Also the consumer can be called multiple times and so
it must reset the stream before it reads it.
The method should validate the input url in all the cases, not only the for the file scheme.

SwingGuiDriver.openMimeResource()
There is a standard class Desktop. I think it performs exactly those operations we need for opening media
files and urls. It declares two methods, open() and browse(). The former launches the application
associated with the provided file type. The latter opens the desktop default browser and navigates to the
provided url. Currently SwingGuiDriver.openMimeResource() always opens the preconfigured browser, so even if
the user has Open Office installed, and thus capable to open the open office files directly, the current
implementation will anyway launch a browser and download the file to a dir. Not very useful I think.

MSG_OPEN_MIME_RESOURCE message handler in p2j.socket.js doesn't handle absolute urls,
buildOpenResourceUrl always prepends p2j.webRoot to the provided path.

SwingGuiDriver.deliverDocumentOutput() still refers to PDF in its javadoc.

DocumentOutputHandler still matches the "print" path.

Please move the PRINT OUTPUT related javadoc from DocumentOutputStorage to GUIPrinterStreamSupport.

Plus I renamed ReportOutputFormat to MediaType and moved it in com.goldencode.p2j.util.

Having a different behavior is OK, if it is a better approach for the user. But we tried using Desktop and it caused a hang in Swing. See #1815-25.

Also, there is the case where isDesktopSupported() is false in which case the Desktop class cannot be used.

If the Desktop class will work properly, then I am OK with using it in the Swing client. But we must have a standard fall-back approach that always works.

MSG_OPEN_MIME_RESOURCE message handler in p2j.socket.js doesn't handle absolute urls,

If the resource is streamed, then it is downloaded from the web client. If it is not streamed, then the template document with absolute url is downloaded
from the web client. Don't understand what is incorrect. Please explain.

If I interpret the program logic correctly, the variable id in case types.MSG_OPEN_MIME_RESOURCE: in p2j.socket.js can be an absolute URL (http://example.com).

It is GET request to the application servlet and the servlet responds with the wrapped document with this url = "http://example.com". The request is built according to the web client design, thus it starts from webRoot in this GET request.

The requirement was to use such url directly: window.location = "https://example.com".

What do you propose? I see two variants:
  1. The servlet responds with redirect responses.
  2. The document loaded from this servlet makes this redirect via jscript on load.
    <script type="text/javascript">
    function onLoad()
    {
       var config = {'isStreamed' : ${isStreamed} };

toASCIIString() only escapes non-ascii characters, but it doesn't produce valid application/x-www-form-urlencoded content. Consider unsafe characters such as '&' or '?'. These will break the resulting uri when put in a query parameter.

Please wait for task branch 3434a to be merged to trunk, then rebase and merge 3474a to trunk. Please confirm that 3474a builds cleanly after the rebase, but it is not necessary to re-run regression testing.

#109 Updated by Sergey Ivanovskiy about 3 years ago

Rev 11268 was rebased over current trunc rev 11246. Committed revision 11269 fixed related to this branch javadoc warnings. The task branch was built successfully.
Now OpenJDK can help to detect only 2 javadoc warnings in these files src/com/goldencode/graphdb/GraphDB.java and src/com/goldencode/p2j/util/EnvironmentOps.java.
Can rev 11269 be merged to trunc?
