  • Category set to PHP API
  • Status changed from New to In Progress
  • Found in version set to 12.4.1

I have added a note in the PHP API documentation for the SaxonProcessor class about the cwd default value and the 256 bytes length limit. It would be good to review 256 bytes length limit needs to be changed in a future release.

Reviewing the documentation changes, I'd like to understand this better.

  1. Does the length limit for cwd only apply on PHP?
  2. Have we imposed this limit for the cwd when creating a SaxonProcessor, or is it an inherited limit from the PHP getcwd() function (which is used as the default)?
  3. What about using the 2-arg constructor SaxonProcessor(boolean $license, string $cwd)? If you supply $cwd here does the length limit apply or not?
  4. In the documentation update, it says that the limit does not apply when using the SaxonProcessor.setcwd() method. What about setcwd() on Xslt30Processor and XsltExecutable?

Yes

We have rightly or wrongly imposed this limit.

This limit does not apply in this case

  1. In the documentation update, it says that the limit does not apply when using the SaxonProcessor.setcwd() method. What about setcwd() on Xslt30Processor and XsltExecutable?

Yes it does not apply on the other Processors.

I've committed an edit for the documentation update, to hopefully be a bit clearer.

I am marking this bug issue as closed.

The 256 string limit is only relevant for the PHP platform.

See: https://www.php.net/manual/en/language.types.string.php#:~:text=A%20string%20is%20a%20series,not%20offer%20native%20Unicode%20support.

A string is a series of characters, where a character is the same as a byte. This means that PHP only supports a 256-character set, and hence does not offer native Unicode support.
