------------------------------
Summary: pn_data_t capacity does not grow above 32768 items
Key: PROTON-892
URL: https://issues.apache.org/jira/browse/PROTON-892
Project: Qpid Proton
Issue Type: Improvement
Components: proton-c
Affects Versions: 0.9, 0.9.1
Reporter: Michael
Priority: Minor
pn_data_grow() function looses half of the available data capacity.
The following happens: when data overflows, pn_data_grow is invoked. It
increases data capacity 2 times and reallocates nodes array. Data capacity is
represented as uint16_t type and so when capacity reaches 32768 items, the
result of multiplication by 2 becomes 0. This makes realloc return null and
crashes the program.
