[jira] [Updated] (PROTON-892) pn_data_t capacity does not grow above 32768 items
[ https://issues.apache.org/jira/browse/PROTON-892?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Alan Conway updated PROTON-892: --- Fix Version/s: (was: 0.10.1) 0.11 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: Bug Components: proton-c Affects Versions: 0.9, 0.9.1, 0.10 Reporter: Michael Assignee: Alan Conway Fix For: 0.11 Attachments: 0003-data-capacity.patch 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
