-----------------------------------------
Summary: Use malloc for buffer allocation in uriparser2
Key: HDFS-16667
URL: https://issues.apache.org/jira/browse/HDFS-16667
Project: Hadoop HDFS
Issue Type: Bug
Components: libhdfs++
Affects Versions: 3.4.0
Environment: Windows 10
Reporter: Gautham Banasandra
Assignee: Gautham Banasandra
Currently, a variable is used to specify the array size in *uriparser2* -
{code:cpp}
static int parse_int(const char *first, const char *after_last) {
const int size = after_last - first;
if (size) {
char buffer[size + 1];
memcpyz(buffer, first, size);
return atoi(buffer);
}
return 0;
}
{code}
https://github.com/apache/hadoop/blob/34e548cb62ed21c5bba7a82f5f1489ca6bdfb8c4/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfspp/third_party/uriparser2/uriparser2/uriparser2.c#L71-L79
This results in the following error on Windows -
{code}
H:\hadoop-hdfs-project\hadoop-hdfs-native-client\src\out\build\x64-Debug\cl :
command line warning D9025: overriding '/W4' with '/w'
uriparser2.c
H:\hadoop-hdfs-project\hadoop-hdfs-native-client\src\main\native\libhdfspp\third_party\uriparser2\uriparser2\uriparser2.c(74,23):
error C2057: expected constant expression
H:\hadoop-hdfs-project\hadoop-hdfs-native-client\src\main\native\libhdfspp\third_party\uriparser2\uriparser2\uriparser2.c(74,23):
error C2466: cannot allocate an array of constant size 0
H:\hadoop-hdfs-project\hadoop-hdfs-native-client\src\main\native\libhdfspp\third_party\uriparser2\uriparser2\uriparser2.c(74,24):
error C2133: 'buffer': unknown size
{code}
Thus, we need to use malloc to fix this.
