@dtalcott Try this:
- Ensure swig, python-devel and gcc is installed
- create
pbs_ifl.i file with below content in it (let’s say file is /tmp/pbsapi/pbs_ifl.i)
%module pbs_ifl
%typemap(out) char ** {
int len,i;
len = 0;
while ($1[len]) len++;
$result = PyList_New(len);
for (i = 0; i < len; i++) {
PyList_SetItem($result,i,PyString_FromString($1[i]));
}
}
%typemap(in) char ** {
if (PyList_Check($input)) {
int size = PyList_Size($input);
int i = 0;
$1 = (char **) malloc((size+1)*sizeof(char *));
for (i = 0; i < size; i++) {
PyObject *o = PyList_GetItem($input,i);
if (PyString_Check(o))
$1[i] = PyString_AsString(PyList_GetItem($input,i));
else {
PyErr_SetString(PyExc_TypeError,"list must contain strings");
free($1);
return NULL;
}
}
$1[i] = 0;
} else {
PyErr_SetString(PyExc_TypeError,"not a list");
return NULL;
}
}
%typemap(out) struct batch_status * {
struct batch_status *head_bs, *bs;
struct attrl *attribs;
char *resource;
char *str;
int i, j;
int len;
char buf[4096];
static char *id = "id";
head_bs = $1;
bs = $1;
for (len=0; bs != NULL; len++)
bs = bs->next;
$result = PyList_New(len);
bs = head_bs;
for (i=0; i < len; i++) {
PyObject *dict;
PyObject *a, *v, *tmpv;
dict = PyDict_New();
PyList_SetItem($result, i, dict);
a = PyString_FromString(id);
v = PyString_FromString(bs->name);
PyDict_SetItem(dict, a, v);
attribs = bs->attribs;
while (attribs) {
resource = attribs->resource;
if (resource != NULL) {
str = malloc(strlen(attribs->name) + strlen(resource) + 2);
sprintf(str, "%s.%s", attribs->name, attribs->resource);
a = PyString_FromString(str);
}
else {
a = PyString_FromString(attribs->name);
}
tmpv = PyDict_GetItem(dict, a);
if (tmpv != NULL) {
char *s = PyString_AsString(tmpv);
str = malloc(strlen(attribs->value) + strlen(s) + 4);
sprintf(str, "%s,%s", attribs->value, s);
v = PyString_FromString(str);
}
else {
v = PyString_FromString(attribs->value);
}
PyDict_SetItem(dict, a, v);
attribs = attribs->next;
}
bs = bs->next;
}
}
%{
#include "pbs_ifl.h"
%}
%include "pbs_ifl.h"
cd /tmp/pbsapi-
source /etc/pbs.conf (Change /etc/pbs.conf according to location of pbs.conf in your system)
-
swig -python -I${PBS_EXEC}/include ./pbs_ifl.i (This command should generate pbs_ifl.py and pbs_ifl_wrap.c in current directory)
-
gcc -Wall -Wno-unused-variable -fPIC -shared -I${PBS_EXEC}/include -I/usr/include/python2.7 -L${PBS_EXEC}/lib -lpbs -o _pbs_ifl.so ./pbs_ifl_wrap.c (This should generate _pbs_ifl.so in current directory)
export LD_LIBRARY_PATH=${PBS_EXEC}/lib:${LD_LIBRARY_PATH}-
export PYTHONPATH=/tmp/pbsapi:${PYTHONPATH} (This is required only when PWD is not /tmp/pbsapi)
- (Optional) Run
ldd /tmp/pbsapi/_pbs_ifl.so and check output and ensure that no missing lib is reported
Now you can use PBS IFL API from python
for example:
python -c "from pbs_ifl import *;import json;c=pbs_connect(None);print json.dumps(pbs_statserver(c, None, None), indent=2)"
