Unlike iconv or the internal converters, ICU consumes truncated multi-
byte sequences at the end of an input buffer. We currently check for a
non-empty raw input buffer to detect truncated sequences, so this fails
with ICU.
It might be possible to inspect the pivot buffer pointers, but it seems
cleaner to implement a `flush` flag for some encoding and I/O functions.
After flushing, we can check for U_TRUNCATED_CHAR_FOUND with ICU, or
detect remaining input with other converters.
Also fix detection of truncated sequences for HTML, XML content and
DTDs with iconv.
Support for RELAX NG used to be enabled together with XML Schema support
(--with-schemas). Now there's a separate option and a new feature macro
LIBXML_RELAXNG_ENABLED.
Long text content can generate multiple "characters" callbacks which can
lead to NOBLANKS removing whitespace in non-whitespace text nodes. So
the NOBLANKS option doesn't even work reliably with the pull parser.
This would be extremely hard to fix.
Unfortunately, `xmllint --format` relies on this option which is another
reason why this feature never really worked.
This implements xmlCtxtParseContent, a better alternative to
xmlParseInNodeContext or xmlParseBalancedChunkMemory. It accepts a
parser context and a parser input, making it a lot more versatile.
xmlParseInNodeContext is now implemented in terms of
xmlCtxtParseContent. This makes sure that xmlParseInNodeContext never
modifies the target document, improving thread safety.
xmlParseInNodeContext is also more lenient now with regard to undeclared
entities.
Fixes#727.
Move source code for xmllint shell to shell.c and move it from the
libxml2 library to the xmllint executable.
Also allow shell to run without XPath and debug modules.
Add stubs for old shell API functions in legacy build mode.
This option would allow for a smaller, but mostly useless minimal build.
But it complicates the symbol availability logic in an insane way and
requires specialized tools like our custom C parser in doc/apibuild.py.
See #717.
