WRT 1.7 I agree with Timo that the enhancements made so far do
validate a new release esp the new NonSequentialParser Timo created
has already proven to solve a number of issues raised. Maybe this
could be the default for the time being?
I wouldn't make it default since it will change which documents can be
processed and which throw an exception. While for most documents it
should be a big step forward there might be some strange/broken
documents for which the standard parser succeeded using workaround and
the new one will fail.
One possibility would be to write a wrapper (as was proposed in
PDFBOX-1199) which first uses the new parser and falls back to the old
one in case of an error.
Another issue is that the new parser needs a file as input for random
access while the old parser also accepts a stream. This could be tackled
by creating a temporary file from stream and use this as input.
I could add this in the next days.
Two further issues:
- need to add method/constructor parameter for specifying password for
encryption
- signed documents are not tested; I would suppose that the signature
string will also be decrypted which is wrong as far as I understand
the spec; there is an implementation for standard parsing
decryption to prevent this but it relies on all objects already loaded
and I need another way to detect which strings not to decrypt
Thus in order to release a stable 1.7 in a short time frame I would
propose keeping the old parser the default but proposing to use the new
parser if possible. If all issues are resolved we may release a 1.8 with
the new parser the default.
Best regards,
Timo
