Allow propagation of errors and retry through StreamDataProvider
StreamDataProvider::provideStreamData now has a rich enough API for it to effectively proxy to pipeStreamData.

2020-04-04 Jay Berkenbilt <ejb@ql.org>
|
||||
|
||||
* Add a new provideStreamData method for StreamDataProvider that
|
||||
allows a success code to be returned and that accepts the
|
||||
suppress_warnings and will_retry methods. This makes it possible
|
||||
to have a StreamDataProvider call pipeStreamData and propagate its
|
||||
results back. This change allows better error handling and
|
||||
recovery when objects are copied from other files and when
|
||||
"immediate copy from" is enabled.
|
||||
|
||||
* Add a new version of QPDFObjectHandle::pipeStreamData whose
|
||||
return value indicates overall success or failure rather than
|
||||
whether nor not filtering was attempted. It should have always
|
||||
been this way. This change was done in a backward-compatible
|
||||
fashion. Previously existing pipeStreamData methods' return values
|
||||
mean the same as always.
|
||||
|
||||
* Add "objectinfo" section to json output. In this release,
|
||||
information about whether each object is a stream or not is
|
||||
provided. There's otherwise no way to tell conclusively from the

This is a list of changes to make next time there is an ABI change.

Comments appear in the code prefixed by "ABI"
|
||||
|
||||
* (Source compatibility) As somewhat discussed in issue 219, the
|
||||
original pipeStreamData in QPDF_Stream has various logic for
|
||||
reporting warnings and letting the caller retry. This logic is not
|
||||
implemented for stream data providers. When copying foreign streams,
|
||||
qpdf uses a stream data provider (QPDF::CopiedStreamDataProvider) to
|
||||
read the stream data from the original file. While a warning is
|
||||
issued for that case, there is no way to actually propagate failure
|
||||
information back through because
|
||||
StreamDataProvider::provideStreamData doesn't take the
|
||||
suppress_warnings or will_retry options, and adding them would break
|
||||
source compatibility.
