Issue and metric API examples

These examples are written in Python, but should be simple enough to understand even without an in-depth knowledge of that language.

All of the examples below use demosthenes, a C/C++ sample project installed with the Klocwork Server package at <server_install>/samples/demosthenes. The demosthenes sample project is only available when the entire Klocwork Server package is installed; it is not included with the Validate Server package. See the README file in that directory for instructions on how to set up the sample project.

You can try out the example scripts on the sample project, or on your own project. If you use them on your own project, you need to change the value for project. You may also need to change the value for host from localhost to your own Klocwork Server host.

For additional information on request parameters, you can visit http(s)://<klocwork_server_host>:<klocwork_server_port>/review/api.

For most of the examples below, with the exception of printing the project list, you can specify a stream by including the full path in the project field. For example: project = "myProj/myStream1/subVariant"

About error handling in these examples

When curl calls are made using the Web API, any errors that are encountered are printed to the console automatically. Note that the Python examples in this topic provide simplified error handling, for example:

Copy
builds = report(url, project, user, action)
print("Existing builds:")
for build in builds:
    print(build)

To better handle errors in your own Python scripts, use a try block:

Copy
try:
    builds = report(url, project, user, action)
except urllib.error.HTTPError as e:
    print("Request failed:", e.reason, ":", e.read())
else:
    print("Existing builds:")
    for build in builds:
        print(build)

About the following examples

This module (kwutil), which is used by the examples below, handles reading ltokens from your system. It has been made into a separate module for readability. Be sure to copy and paste the code below to create the kwutil module.

Copy
import os.path


def get_token(host, port, user):
    ltoken = os.path.normpath(os.path.expanduser("~/.klocwork/ltoken"))
    ltoken_file = open(ltoken, 'r')
    for r in ltoken_file:
        rd = r.strip().split(';')
        if rd[0] == host and rd[1] == str(port) and rd[2] == user:
            ltoken_file.close()
            return rd[3]
    ltoken_file.close()

Example: Search for all critical issues

This example script searches for all critical issues (with severities 1, 2 and 3) in the latest build of the Demosthenes sample project.

Example: Print the project list

This example shows how to print the list of projects.

By default, the query returns a list of base projects only. You can also have the query show all base projects and streams by specifying the include_streams flag with a value of true (default is false). For example, include a query with the following values:

  • action=projects

  • user=someone

  • include_streams=true

...returns the following aggregate results:

{"id":"project1","name":"project1","creator":"someone","description":""}

{"id":"project1_sub1","name":"project1/sub1","creator":"someone","description":"","tags":["s"]}

{"id":"project1_sub2","name":"project1/sub1/sub2","creator":"someone","description":""}

Aggregated search results

By default, the metrics API generates results on a per file basis. To generate aggregated search results for all files in a given query, specify the aggregate flag with a value of true (default is false). The following example shows aggregated search results:

A query with the following values:

  • action=metrics
  • user=someone
  • query=metric:+LOC_FILE
  • project=demosthenes
  • aggregate=true

...returns the following aggregate results:

{"tag":"LOC_FILE","sum":8113.0,"min":3.0,"max":966.0,"entries":47}

The aggregate flag is only really useful for data that has relative meaning. In other words, if a metric can be summed, or if max and min values can be determined.

Excluding system files from search results

By default, the metrics API generates results based on all files. You can have the query omit system files by specifying the exclude_system_files flag with a value of true (default is false), for example:

A query with the following values:

  • action=metrics
  • user=someone
  • project=demosthenes
  • aggregate=true
  • exclude_system_files=true
  • query=metric:+LOC_FILE

Example curl request:

curl --data "action=metrics&user=someone&project=demosthenes&exclude_system_files=true&query=metric:%2bLOC_FILE&aggregate=true" http://localhost:8080/review/api

...returns the following results:

{"tag":"LOC_FILE","sum":322.0,"min":3.0,"max":68.0,"entries":13}

Importing server settings, projects and code review

You can also use the API to import server settings, projects or code reviews via the command line. This can be done for each of these methods as follows:

To import server settings

The following example imports authentication configuration, permissions, custom metrics, reports definitions and e-mail subscription settings.

Copy
import getpass
import urllib.error
import urllib.parse
import urllib.request

import kwutil


def import_server_configuration(url, user, sourceURL, sourceAdmin, sourcePassword):
    values = {"action": "import_server_configuration",
              "user": user,
              "sourceURL": sourceURL,
              "sourceAdmin": sourceAdmin}
    if sourcePassword is not None:
        values["sourcePassword"] = sourcePassword
    login_token = kwutil.get_token(host, port, user)
    if login_token is not None:
        values["ltoken"] = login_token
    data = urllib.parse.urlencode(values)
    data = data.encode('utf-8')
    req = urllib.request.Request(url, data)
    urllib.request.urlopen(req)


host = "localhost"
port = 8080
user = getpass.getuser()

sourceURL = "http://oldhost:8080"
sourceAdmin = "old admin user name"
sourcePassword = None

url = "http://%s:%d/review/api" % (host, port)

try:
    import_server_configuration(url, user, sourceURL, sourceAdmin, sourcePassword)
    print("Imported server configuration!")
except urllib.error.HTTPError as e:
    print("Request failed:", e.reason, ":", e.read())

To import a project

The following example imports data collected by Klocwork for the specified project.

Copy
import getpass
import urllib.error
import urllib.parse
import urllib.request

import kwutil


def import_project(url, user, project, sourceURL, sourceAdmin, sourcePassword):
    values = {"action": "import_project",
              "user": user,
              "project": project,
              "sourceURL": sourceURL,
              "sourceAdmin": sourceAdmin}
    if sourcePassword is not None:
        values["sourcePassword"] = sourcePassword
    login_token = kwutil.get_token(host, port, user)
    if login_token is not None:
        values["ltoken"] = login_token
    data = urllib.parse.urlencode(values)
    data = data.encode('utf-8')
    req = urllib.request.Request(url, data)
    urllib.request.urlopen(req)


host = "localhost"
port = 8080
user = getpass.getuser()

project = "projectA"
sourceURL = "http://oldhost:8080"
sourceAdmin = "old admin user name"
sourcePassword = None

url = "http://%s:%d/review/api" % (host, port)

try:
    import_project(url, user, project, sourceURL, sourceAdmin, sourcePassword)
    print("Imported project!")
except urllib.error.HTTPError as e:
    print("Request failed:", e.reason, ":", e.read())

To check import status

You can use this API method to check the status of importing your server settings, project or code review.

Copy
import getpass
import json
import sys
import time
import urllib.error
import urllib.parse
import urllib.request

import kwutil


class ImportStatus(object):
    def __init__(self, project, attrs):
        self.project = project
        self.stage = attrs["stage"]
        self.progress = attrs["progress"]
        self.failed = attrs["failed"]
        self.hasWarnings = attrs["hasWarnings"]
        self.projectReady = attrs["projectReady"]
        self.complete = attrs["complete"]

    def __str__(self):
        return "Project: %s\n\tStage: %s | Progress: %s%% | Failed: %s | Warnings: %s | Project Ready: %s | Complete: %s" % (
            self.project, self.stage, self.progress, self.failed, self.hasWarnings, self.projectReady, self.complete)


def import_status(url, user):
    values = {"action": "import_status", "user": user}
    login_token = kwutil.get_token(host, port, user)
    if login_token is not None:
        values["ltoken"] = login_token
    data = urllib.parse.urlencode(values)
    data = data.encode('utf-8')
    req = urllib.request.Request(url, data)
    response = urllib.request.urlopen(req)
    importStatus = []
    for record in response:
        attrs = json.loads(record)
        for key in attrs.keys():
            importStatus.append(ImportStatus(key, attrs[key]))
    return importStatus


def import_project(url, user, project, sourceURL, sourceAdmin, sourcePassword=None, ):
    values = {"action": "import_project",
              "user": user,
              "project": project,
              "sourceURL": sourceURL,
              "sourceAdmin": sourceAdmin}
    if sourcePassword:
        values["sourcePassword"] = sourcePassword
    login_token = kwutil.get_token(host, port, user)
    if login_token is not None:
        values["ltoken"] = login_token
    data = urllib.parse.urlencode(values)
    data = data.encode('utf-8')
    req = urllib.request.Request(url, data)
    urllib.request.urlopen(req)


def wait_for_import(url, user, project):
    is_timeout = False
    TIME_OUT = time.time() + 60 * 20
    incomplete = [project]

    if len(incomplete) == 0:
        return

    while True:
        for status in import_status(url, user):
            if status.project != project:
                continue

            # If all operations are complete then exit the loop
            if len(incomplete) == 0:
                break

            if status.project in incomplete:
                is_timeout = time.time() > TIME_OUT

            if status.complete or status.failed:
                print(status.stage)
                incomplete.pop(incomplete.index(status.project))
                break
            elif is_timeout:
                print("Import of project '%s' took longer than expected." % status.project)
                print("Check if import is still progressing.")
                sys.exit(-1)

        # If all projects are complete then exit the loop
        if len(incomplete) == 0:
            break

        time.sleep(10)


host = "localhost"
port = 8080
user = getpass.getuser()

url = "http://%s:%d/review/api" % (host, port)

project = "demosthenes"
sourceURL = "http://oldhost:8080"
sourceAdmin = "old admin user name"

try:
    import_project(url, user, project, sourceURL, sourceAdmin)
    print("Import started")
    wait_for_import(url, user, project)
except urllib.error.HTTPError as e:
    print("Request failed:", e.reason, ":", e.read())
