I am not really sure why that happened but it should be there now

[Matthias Brantner (matthias-brantner)]

I'm not entirely sure but the diff now only shows whitespace differences in generated files. I didn't find any change which adds one of the new functions.

The diff below just show the diff for the errors in which the error codes FOUT1170 and FOUT1190 where added the diffs for the implementation should be on
sequence_impl.cpp for unparsed-text(), unparsed-text-available(), environment-variable(), available-environments-variables()
and in collections_impl.cpp there is uri-collection()

[Matthias Brantner (matthias-brantner)]

- dynamic_context::get_environment_variable(const zstring varname)

should be

dynamic_context::get_environment_variable(const zstring& varname)

- spaces before "(". for example "if (...) instead of if(...)"

- all new functions in sequences_impl.cpp are indented with two spaces. the other functions are not

- if(result)
{
  STACK_PUSH(true, state);
}
STACK_PUSH(false, state);

could be written as STACK_PUSH(result!=NULL, state);

- In FnEnvironmentVariableIterator::nextImpl, the check if(consumeNext(item, theChildren[0].getp(),planState)) is not necessary. consumeNext always returns true because the functions is defined to accept xs:string (not xs:string?)

- item->getString() returns a const zstring&. This should be the type of the variable.

- store::Item_t item2 is not used in the function

- In FnAvailableEnvironmentVariablesIterator::nextImpl, the line a = result->getStringValue().c_str(); and the variable a don't seem to be necessary

- The environment-related functions should be specified using

<zorba:methods>
  <zorba:accessesDynCtx returnValue="true"/>
</zorba:methods>

- All the lines after 14.8.5 fn:unparsed-text have windows line endings

- you can check using transcode::is_necessary if a encoding is supported

- It's unclear when the original stream for unparsed-text is released. This seems to be a memory leak.

- The unparsed-text related functions should be specified as

<zorba:methods>
  <zorba:accessesDynCtx returnValue="true"/>
  <zorba:isSource returnValue="true"/>
</zorba:methods>

- What's the default encoding for unparsed-text?

[Juan Zacarias (juan457)]

I will make all those changes, Thanks.

and answering your questions

> - you can check using transcode::is_necessary if a encoding is supported
If I am not wrong I am using it that way.

> - What's the default encoding for unparsed-text?
UTF-8

The thing with the encoding is that the encoding is defined in the call of the function unparsed-text and unparsed-text-available being initialized with UTF-8 as a default, should I change the default definition to be inside readDocument function so that you don't have to defined in each function?

My bad, I meant transcode::is_supported should be used.

OK, got it. It's fine as it is.

for the original stream of unparsed-text which variable you mean?

[Matthias Brantner (matthias-brantner)]

> > - It's unclear when the original stream for unparsed-text is released. This

> for the original stream of unparsed-text which variable you mean?
Yes, the stream you receive from the StreamResource contains a stream which is wrapped into a streamable string. The stream in the streamable string is released but the original one isn't. I think you need to remember it in a map and release it when the stream you created is released.

One more doubt regarding this, I got a little bit confused while trying to fix this, the one you mean is the stream that is inside the StreamResource, is the one that needs to be released right? since I had to set the StreamReleaser of it to a nullptr

[Sorin Marian Nasoi (sorin.marian.nasoi)]

I ran
ctest -R xquery_3_0
on this branch, and:

- the following functions from F&O 3.0 spec are still not implemented:
filter#2 fold-left#3 fold-right#3 function-lookup#2 map#2 map-pairs#3 parse-xml-fragment#1 unparsed-text-lines#1 unparsed-text-lines#2 has-children#0 nilled#0 path#0 path#1

- the following functions are in the fn namespace (according to the introspection module) and the F&O 3.0 spec state that they should not be there:
parse-xml#2 partial-apply#2 partial-apply#3

So it seems that all functions linked to this commit are implemented.

[Juan Zacarias (juan457)]

the errors mentioned should be solved now.
let me know if there is any other thing to be changed before merging.

[Matthias Brantner (matthias-brantner)]

- the unparsed-text-lines function doesn't really stream because it materializes all the lines in a vector before returning them. Instead, the iterator should keep the istream in it's state and return the lines as they are parsed from the stream.
- the two readDocument functions share a lot of code which should be factorized
- please add spaces after keywords like if and while to be consistent with the other conventions in the sequences_impl.cpp file
- Normilize => Normalize
- wrong comment for the FnUnparsedTextLinesIterator::nextImpl function (14.8.6 fn:unparsed-text-lines)
- I think the unparsed-text-lines function returns an eventually empty last line. However, the spec says that it shouldn't return such an empty string.
- unparsed-text-lines should return the empty sequence if there are no lines in the input. However, it seems to raise FOUT1170.

Just one question about this, the Item returned by the function for each line should be a Stream then?

No, I don't think that's necessary. A line should be relatively short. It would probably be overhead to stream a single line.

[Juan Zacarias (juan457)]

Errors are Fixed

[Matthias Brantner (matthias-brantner)]

- There seems to be a merge conflict.
- The stream stored in the state must be deleted using the streamReleaser
- The lErrorMessage stream is passed as parameter but the errors only take one parameter.
- The LoadProperties are not used anywhere
- The following can be simplified
  if(getline(*state->theStream, streamLine))
  {
    do
    {
      STACK_PUSH(GENV_ITEMFACTORY->createString(result, streamLine), state);
    }
    while (getline(*state->theStream, streamLine));
  }
  else
    STACK_PUSH(false, state);

=>
    while (getline(*state->theStream, streamLine))
    {
      STACK_PUSH(GENV_ITEMFACTORY->createString(result, streamLine), state);
    }

review: Needs Fixing

[Chris Hillery (ceejatec)]

Regarding point 2: Remember that the StreamReleaser and the istream must always be kept together as a pair, and the StreamReleaser must be the only way that you clean up the istream. Here, you are deleting the istream directly (bad), and by setting the StreamReleaser on theStreamResource to nullptr, you're breaking up the pair (also bad).

In this case, the StreamResource is already maintaining the pair, and so you can actually make your life easier by just maintaining ownership of the StreamResource and making sure that IT is deleted when you're done. In that case you never have to look at StreamReleaser at all. To do this:

 - In FnUnparsedTextLinesIterator::nextImpl(), change lResource.get() to lResource.release(). By doing this, you take ownership of the StreamResource (so that the auto_ptr<> won't delete it).

 - Later in the same function, don't call state->theStreamResource->setStreamReleaser(nullptr);.

 - In FnUnparsedTextLinesIteratorState::reset(), just delete theStreamResource, and then set theStream and theStreamResource to 0. Deleting the StreamResource will correctly clean up the stream by calling the StreamReleaser.

If I understand Matthias, you will also need to delete theStreamResource in the state's destructor, in case of exceptions. (That's why you set theStreamResource to 0 in reset(), so you can't accidentally delete it twice.)

-      We have not bothered to insert the licensing arrangement into the text of
