Welcome to IIQTools’s documentation!¶
Contents:
Getting Started¶
Install and Upgrade¶
This section provides directions to install or upgrade the IIQTools package for your instance of InsightIQ.
Installing the RPM¶
This is by far the easiest way to install IIQTools.
Download the newest RPM here
Copy the RPM file onto the machine running InsightIQ
Install with this command, replacing
</path/to/rpm>
with the literal file path:$ sudo yum install --disablerepo=* <path/to/rpm>
Installing Python pip¶
Python pip is the preferred way to install Python packages. I f your instance of InsightIQ doesn’t have pip installed, there are some pretty simple directions at:
https://pip.pypa.io/en/stable/installing/
Note
The --upgrade
flag is automatically ignored if you’re performing an initial install
With Internet connection¶
To install or upgrade the IIQTools package to your instance of InsightIQ run:
$ sudo pip install --upgrade iiqtools
Setting up a development environment¶
This section is only for settings up a development environment. Only follow these directions if you intend to contribute source code to the project.
If you have the know-how to build and test IIQTools on MacOS or Windows, we’d love to get a Pull Request from you updating this section!
Linux¶
These are non-Python libraries required to build and test IIQTools. Use the builtin packagemanger (i.e. apt-get, yum, dnf) to install these packages.
RHEL/CentOS/Fedora:
- make
- python-devel
- postgresql-devel
- postgresql
- redhat-rpm-config
Ubuntu:
- make
- python-dev
- postgresql
- libpq-dev
Before installing the Python dependencies, it’s highly encouraged to configure a Python Virtualenv for working with IIQTools.
Once you’ve got your virtualenv configured and activated, run this command to install the dependencies for building and testing IIQTools:
$ pip install -r requirements-dev.txt
Once you’ve installed those dependencies, you can run all the unit tests like this:
$ make test
And generate the docs with:
$ make docs
Or clean up everything with:
$ make clean
Scripts & Tools¶
This section goes over the scripts and tools added to your InsightIQ instance when you install the IIQTools package. Each section should have some examples of what running the script looks like, or what the tool does.
iiqtools_gather_info¶
The point of this script is to provide a convenient way for users to collect logs and configuration information about InsightIQ so that remote support can investigate any issues that they are having.
Examples (assuming your running as the root
users)¶
Printing the help message:
[root@localhost ~]$ iiqtools_gather_info --help
usage: iiqtools_gather_info [-h] [--output-dir OUTPUT_DIR] --case-number
CASE_NUMBER
Generate a .tar file for debugging InsightIQ
optional arguments:
-h, --help show this help message and exit
--output-dir OUTPUT_DIR
The directory to write the .tgz file to (default:
/home/administrator)
--case-number CASE_NUMBER
The Service Request number. Used in naming tar file.
(default: None)
Generating a gather:
[root@localhost ~]$ iiqtools_gather_info --case-number 1234
2017-09-11 14:53:45,298 - INFO - Collecting config information
2017-09-11 14:53:46,123 - INFO - Collecting log files
2017-09-11 14:53:48,126 - INFO - Log gather complete
2017-09-11 14:53:48,126 - INFO - Created log file /home/administrator/IIQLogs-sr1234-1505166825.tgz
Forgetting to provide the --case-number
argument:
[root@localhost ~]$ iiqtools_gather_info
usage: iiqtools_gather_info [-h] [--output-dir OUTPUT_DIR] --case-number
CASE_NUMBER
iiqtools_gather_info: error: argument --case-number is required
Outputting the tar file to a different directory:
[root@localhost ~]$ iiqtools_gather_info --case-number 1234 --output-dir /datastore
2017-09-11 14:55:44,195 - INFO - Collecting config information
2017-09-11 14:55:44,451 - INFO - Collecting log files

2017-09-11 14:55:45,957 - INFO - Created log file /datastore/IIQLogs-sr1234-1505166944.tgz
iiqtools_tar_to_zip¶
Starting with InsightIQ 3.2, you could export a cluster’s database from one instance, then import it later or on another InsightIQ instance. Initially, the exported data was in tar file format, but in InsightIQ 4.1 we switched to using a zip file. The switch was to resolve a bug where importing large exports would time out. The data contained within the tar and the zip files is identical; only the compression format has changed. This means that if we convert an old tar export to zip, we can use that archive in newer versions of InsightIQ.
Use cases for this script:
- Migration Upgrades
- Instead of upgrading an existing deployment, you export the data on your old instance, use this script to convert the format, and then import that data on a new deployment of InsightIQ. This approach is ideal for OVA deployments of InsightIQ because the newer OVAs for InsightIQ have the latest security patches applied, and the root partition is configured with LVM.
- Maintain Legacy Exports
- With the upgrade to 4.1, any datastore exports created on the older version of InsightIQ are no longer compatible. This script will update the format of those older datastore exports so you can continue to use them in newer versions of InsightIQ.
Usage Examples¶
Obtaining the help message:
[administrator@localhost ~]$ iiqtools_tar_to_zip --help
usage: iiqtools_tar_to_zip [-h] -s SOURCE_TAR [-o OUTPUT_DIR]
Convert .tar to .zip for IIQ datastore export files
optional arguments:
-h, --help show this help message and exit
-s SOURCE_TAR, --source-tar SOURCE_TAR
The source .tar file to convert to .zip (default:
None)
-o OUTPUT_DIR, --output-dir OUTPUT_DIR
The (default: /home/administrator)
Simple usage (this export was only about 20MB in size):
[administrator@localhost ~]$ iiqtools_tar_to_zip --source-tar /datastore/insightiq_export_1505412864.tar.gz

Example Usage:
[administrator@localhost ~]$ iiqtools_version
InsightIQ: 4.1.1.3
IIQTools: 0.1.0
iiqtools_patch¶
A tool for installing, uninstalling, and displaying patches to IsightIQ source code.
Note
Installing and uninstalling requires the InsightIQ application to be restarted.
Running the iiqtools_patch
tool with sudo
will automatically restart the application.
Display all installed patches:

iiqtools_cluster_backup¶
The point of this tool is to make automating backups of your cluster data easy; just setup a crontab!
InsightIQ supports exporting/importing cluster data, but it requires a user to click through the UI. This tool calls the same API as the UI, but instead does the API call from the CLI instead of a browser. The API that is called requires a user with elevated privileges for the backup to work. Attempting to use a read-only user will cause your backups to fail. To be clear, this tool needs an admin of InsightIQ, not the host Linux machine running the InsightIQ application.
Note
It’s highly recommend to setup a local user instead of using the default administrator
.
Setting up the iiq_backup
user account¶
The default administrator
account used by InsightIQ has sudo
power over the host
machine running the application. In other words, that account is root by a different name.
The iiqtools_cluster_backup tool requires a password to be supplied, either as a CLI argument
or interactively. When setting up a crontab, you must use the CLI argument option.
This means that the password will be in clear text in the crontab file. TODO link to stackoverflow This is the
main reason that setting up an alternate account is a great idea! All local users
on the host machine running InsightIQ are by default admin account in the application.
To create the iiq_backup
user account, run the following command:
[administrator@localhost ~]$ sudo useradd iiq_backup && sudo passwd iiq_backup
Once that user is created, you’ll have to give them access to the key file:
[administrator@localhost ~]$ sudo chmod 440 /etc/isilon/secret_key
[administrator@localhost ~]$ sudo chown :iiq_backup /etc/isilon/secret_key
Usage Examples¶
Here are some examples of using the iiqtools_backup_cluster tool.
Printing available clusters:
[administrator@localhost ~]$ iiqtools_cluster_backup --show-clusters
Clusters monitored by InsightIQ
-------------------------------
myCluster
myOtherCluster
isi-nas-01
Interactively supplying the password:
[administrator@localhost ~]$ iiqtools_cluster_backup --clusters myOtherCluster --location /mnt/backups --username iiq_backup
Please enter the password for iiq_backup :
Cluster archive underway.
To monitor status you can either follow /var/log/insightiq_export_import.log or
check the Settings page in the InsightIQ UI.
Backing up to an NFS export:
[administrator@localhost ~]$ iiqtools_cluster_backup --clusters myCluster --location 10.7.1.2:/ifs/data --username iiq_backup --password a
Cluster archive underway.
To monitor status you can either follow /var/log/insightiq_export_import.log or
check the Settings page in the InsightIQ UI.
Backing up multiple clusters:
[administrator@localhost ~]$ iiqtools_cluster_backup --clusters myCluster isi-nas-01 --location /mnt/backups --username iiq_backup --password a
Cluster archive underway.
To monitor status you can either follow /var/log/insightiq_export_import.log or
check the Settings page in the InsightIQ UI.
Trying to backup a cluster while the InsightIQ application is offline:
[administrator@localhost ~]$ iiqtools_cluster_backup --clusters myCluster --location 10.7.1.2:/ifs/data --username iiq_backup --password a
***Unable to communicate with the InsightIQ API***
Please verify that the insightiq service is running and try again
Limiting the number of historic backup files to 6:
[administrator@localhost ~]$ iiqtools_cluster_backup --max-backups 6--clusters myCluster isi-nas-01 --location /mnt/backups --username iiq_backup --password a
Note
The --max-backups
argument only deletes an old backup if the existing number
of backups before starting a new backup is larger than the supplied value.
For example, if you set --max-backups
to 4 and the directory you are backing
up to already has 4 previous backups, then (assuming the backup completes successfully)
you will have a grand total of 5 backups in that directory.
Crontab Examples¶
This section assumes you’ve created the iiq_backup
user account.
Note
Only one backup can happen at a time.
Backup every Monday at 1:00 AM
0 1 * * * mon iiqtools_cluster_backup --clusters myCluster myOtherCluster isi-nas-01 --location isi-nas.corp:/ifs/iiq/backups --username iiq_backup --password a
Backup only the cluster you care about, once a month at 2:00 AM
0 2 1 * * * iiqtools_cluster_backup --clusters myCluster --location /mnt/backups --username iiq_backup --password a
Contributing¶
We love contributions from anyone! What’s a contribution you ask, well just about anything.
Feature Requests¶
Got an idea for a script or tool to add to IIQTools, but need some help making it? File an issue on Github. Please keep in mind that we can’t alter InsightIQ source code, so there’s literal zero chance of adding something to the InsightIQ UI.
Bugs¶
What is a bug? Well, anything that impacts your ability to use IIQTools. This includes things like:
- “the script generated this traceback”
- “your docs are wrong”
- “that script didn’t do what I thought it would”
but it’s not limited to that. This package exist to make your life easier, so if part of it is confusing, even some part of the process, let us know by filing an issue on Github.
Note
If it’s some sort of code bug, please provide the version of InsightIQ, IIQTools, and any tracebacks that were generated. We need that information to fix the bug.
Source code¶
Wow! Thanks for wanting to add some source code to IIQTools. The process is pretty standard Github stuff:
- Fork the repo
- Add code to your fork
- Put up a Pull Request to our master branch
There are a few of rules to keep in mind:
- Write some unit tests. We’re not demanding 100% coverage, but the closer the better.
- Don’t incorporate any additional 3rd party libraries. Some of our users cannot access the internet, and adding 3rd party libs complicates the install process.
- Follow our docstring format (look at existing code), and update the docs directory as necessary.
Source code docs¶
This is all auto-generated documentation from the IIQTools source code. It defines the different modules, their APIs, and some examples.
iiqtools.exceptions¶
Centralized location for all custom Exceptions
-
exception
iiqtools.exceptions.
CliError
(command, stdout, stderr, exit_code, message='Command Failure')[source]¶ Raised when an CLI command has a non-zero exit code.
Parameters: - command (String) – The CLI command that was ran
- stdout (String) – The output from the standard out stream
- stderr (String) – The output from the standard error stream
- exit_code – The exit/return code from the command
-
exception
iiqtools.exceptions.
DatabaseError
(message, pgcode)[source]¶ Raised when an error occurs when interacting with the InsightIQ database
Attribute pgcode: The error code used by PostgreSQL. https://www.postgresql.org/docs/9.3/static/errcodes-appendix.html Attribute message: The error message
iiqtools.utils¶
The utils module for the IIQTools package. These are common-need/generic functions for making scripts/tools for use with InsightIQ.
cli_parsers¶
This module contains functions that parse stdout of a CLI command into a usable Python data structure.
-
iiqtools.utils.cli_parsers.
df_to_dict
(output)[source]¶ Parse the output from the command df into a dictionary
Returns: Dictionary Parameters: output (String) – Required The pile of stuff outputted by running df
database¶
Utilities for interacting with the InsightIQ database
-
class
iiqtools.utils.database.
Column
[source]¶ A database column consiting of the column’s name, and it’s type
Type: namedtuple
Parameters: - name – The column’s name
- type – The database type for the given column (i.e. int, float, double)
-
class
iiqtools.utils.database.
Database
(user='postgres', dbname='insightiq')[source]¶ Simplifies communication with the database.
The goal of this object is to make basic interactions with the database simpler than directly using the psycopg2 library. It does this by reducing the number of API methods, providing handy built-in methods for common needs (like listing tables of a database), auto-commit of transactions, and auto-rollback of bad SQL transactions. This object is not indented for power users, or long lived processes (like the InsightIQ application); it’s designed for shorter lived “scripts”.
Parameters: - user (String, default postgres) – The username when connection to the databse
- dbname (String, default insightiq) – The specific database to connection to. InsightIQ utilizes a different database for every monitored cluster, plus one generic database for the application (named “insightiq”).
-
execute
(sql, params=None)[source]¶ Run a single SQL command
Returns: Generator
Parameters: - sql (String) – Required The SQL syntax to execute
- params (Iterable) – The values to use in a parameterized SQL query
This method is implemented as a Python Generator: https://wiki.python.org/moin/Generators This means you are suppose to iterate over the results:
db = Database() for row in db.execute("select * from some_table;"): print row
If you want all the rows as a single thing, just use
list
:db = Database() data = list(db.execute("select * from some_table;")
But WARNING that might cause your program to run out of memory and crash! That reason is why this method is a generator by default ;)
To perform a parameterized query (i.e. avoid SQL injection), provided the parameters as an iterable:
db = Database() # passing in "foo_column" alone would try and string format every # character of "foo_column" into your SQL statement. # Instead, make "foo_column" a tuple by wrapping it like ("foo_column",) # Note: the trailing comma is required. data = list(db.execute("select %s from some_table", ("foo_column",)))
-
executemany
(sql, params)[source]¶ Run the SQL for every iteration of the supplied params
This method behaves exactly like execute, except that it can perform multiple SQL commands in a single transaction. The point of this method is so you can retain Atomicity when you must execute the same SQL with different parameters. This method isn’t intended to be faster than looping over the normal execute method with the different parameters.
Returns: Generator
Parameters: - sql (String) – Required The SQL syntax to execute
- params (Iterable) – Required The parameterized values to iterate
-
isolation_level
¶ Set the isolation level of your connnection to the database
-
primary_key
(table)[source]¶ Given a table, return the primary key
Note
If you supply a timeseries table that DOES NOT have an EPOC timestamp in the name, you will get zero results. For timeseries tables, supply a table that contains the EPOC timestamps to see the primary key.
Returns: Tuple of namedtuples -> (Column(name, type), Column(name, type)) Parameters: table (String) – Required The table to obtain the primary key from
generic¶
This module contains miscellaneous utility functions
-
iiqtools.utils.generic.
check_path
(cli_value)[source]¶ Validate that the supplied path is an actual file system directory.
This function is intended to be used with the argparse lib as an argument type.
Raises: argparse.ArgumentTypeError Returns: String Parameters: cli_value (String) – The value supplied by the end user
logger¶
-
iiqtools.utils.logger.
get_logger
(log_path=None, stream_lvl=0, file_lvl=20)[source]¶ Factory for making logging objects
The verbosity of the logs are configurable as defined by the official Python documentation: https://docs.python.org/2/library/logging.html#logging-levels
Returns: logging.Logger
Raises: AssertionError on bad parameter input
Parameters: - log_path (String) – Required The absolute file path to write logs to
- stream_lvl (Integer, default 20) – Set to print log messages to the terminal.
- file_lvl – How verbose the log file messages are. This value cannot be zero.
shell¶
This module reduces boilerplate when interacting with the command shell, i.e. BASH.
Example A:
>>> result = shell.run_cmd('ls')
>>> print result.stdout
README.txt
someOtherFile.txt
>>> print result.stderr
>>> result.exit_code
0
Example B:
>>> # run_cmd does not support the Unix Pipeline
>>> result = shell.run_cmd('cat foo.txt | grep "not supported"')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
raise CliError(cli_syntax, stdout, stderr, exit_code)
iiqtools.exceptions.CliError: Command Failure: cat foo.txt | grep "not supported"
-
class
iiqtools.utils.shell.
CliResult
[source]¶ The outcome from running a CLI command
Type: collections.namedtuple
Parameters: - command (String) – The CLI command that was ran
- stdout (String) – The output from the standard out stream
- stderr (String) – The output from the standard error stream
- exit_code – The exit/return code from the command
-
iiqtools.utils.shell.
run_cmd
(cli_syntax)[source]¶ Execute a simple CLI command.
This function blocks until the CLI command returns and does not support the Unix pipeline.
Returns: CliResult - namedtuple Raises: CliError (when exit code is not zero) Parameters: cli_syntax (String) – The CLI command to run.
versions¶
This module make obtaining and comparing version strings easy!
-
class
iiqtools.utils.versions.
PatchInfo
[source]¶ Describes the state of patches for InsightIQ
Parameters: - iiq_dir (String) – The file system path where InsightIQ source is located.
- patches_dir (String) – The file system path where patches for InsightIQ are stored.
- specific_patch (String) – Only populated when a patch is being installed/removed/read.
- is_installed – If
specific_patch
is installed or not. - readme (String) – The README.txt for
specific_patch
if applicable. - all_patches (Tuple) – All currently installed patches.
Type is_installed: Boolean
-
class
iiqtools.utils.versions.
Version
(version, name)[source]¶ Implements comparison operators for common version strings
Only versions strings upwards of 4 digits and consisting only of numbers is supported. Version strings breakdown into
major
,minor
,patch
, andbuild
.Example:
>>> version_as_string = '1.2.3' >>> version = Version(name='myPackage', version=version_as_string) >>> version.major 1 >>> version.patch 3 >>> type(version.minor) <type 'int'> >>> type(version.build) <type 'NoneType'>
Comparing Versions:
>>> v1 = Version(name='myPackage', version='1.2.3') >>> v2 = Version(name='newPackage', version='1.4.0') >>> v1 < v2 True >>> v2 >= v1 True >>> v2 == v1 False
The Version object also support comparison of string versions:
>>> v1 = Version(name='foo', version='4.5') >>> v1 > '5.0' False
It’s worth noting, more specific versions (that would otherwise be equal), are considered greater:
>>> v1 = Version(name='bar', version='1.2.0') >>> v1 > '1.2' True
This is because a version without a value is None, and zero is greater than None in Python:
>>> 0 > None True
-
iiqtools.utils.versions.
get_iiq_version
()[source]¶ Obtain the version of InsightIQ installed
Returns: iiqtools.utils.versions.Version
-
iiqtools.utils.versions.
get_iiqtools_version
()[source]¶ Obtain the version of iiqtools installed
Returns: iiqtools.utils.versions.Version
-
iiqtools.utils.versions.
get_patch_info
(specific_patch, log)[source]¶ Obtain the current state of patches for InsightIQ
Returns: PatchInfo (namedtuple)
Parameters: - specific_patch (String) – Required The name of a patch that’s being installed/removed/read.
- log (logging.Logger) – Required The logging object. This param is really here to make unit testing easier -> https://en.wikipedia.org/wiki/Dependency_injection
insightiq_api¶
This module is for performing privileged API calls to InsightIQ.
-
exception
iiqtools.utils.insightiq_api.
ConnectionError
[source]¶ Unable to establish an connection to the OneFS API
-
class
iiqtools.utils.insightiq_api.
InsightiqApi
(username, password, verify=False)[source]¶ An authenticated connection to the InsightIQ API
This object is a simple wrapper around a requests Session. The point of wrapping the requests Session object is to remove boiler plate code in making API calls to InsightIQ, and to auto-handle authenticating to the API. The most noteworthy changes to this object and how you use the requests Session object is that you must provide the username and password when instantiating the object, and when you make a request, you only supply the URI end point (i.e. not the http://my-host.org:8080 part).
Supports use of
with
statements, which will automatically handle creating and closing the HTTP session with InsightIQ.Example:
>>> with InsightiApi(username='administrator', password='foo') as iiq: response = iiq.get('/api/clusters')
Parameters: - username (String) – Required The name of the administrative account for InsightIQ
- password (String) – Required The password for the administrative account being used.
- verify (Boolean) – Perform SSL/TLS cert validation using system certs. Setting to True will likely cause issues when using a self-signed SSL/TLS cert. Default is False.
-
delete
(endpoint, params=None, data=None, headers=None, **kwargs)[source]¶ Perform an HTTP DELETE request
Returns: PyObject
Parameters: - endpoint (String) – Required The URI end point of the InsightIQ API to call
- params (Dictionary) – The HTTP parameters to send in the HTTP request
- data (PyObject) – The HTTP body content to send in the request. The Python object supplied (i.e. list, dict, etc) will be auto-converted to JSON string.
- headers (Dictionary) – Any additional HTTP headers to send in the request
-
get
(endpoint, params=None, data=None, headers=None, **kwargs)[source]¶ Perform an HTTP GET request
Returns: PyObject
Parameters: - endpoint (String) – Required The URI end point of the InsightIQ API to call
- params (Dictionary) – The HTTP parameters to send in the HTTP request
- data (PyObject) – The HTTP body content to send in the request. The Python object supplied (i.e. list, dict, etc) will be auto-converted to JSON string.

class
iiqtools.utils.insightiq_api.
Parameters
(*args, **kwargs)[source]¶ Object for working with HTTP query parameters
This object supports the Python dictionary API, and lets you define the same HTTP query parameter more than once. Additional definitions for the same query parameter creates a new entry in the underlying list. This decision makes it simple to iterate Parameters to build up the HTTP query string because you do not have to iterate parameter values. Because you can define the same parameter more than once, using the standard dictionary API will only impact the first occurrence of that parameter. To modify a specific parameter, you must use the methods in this class which extend the dictionary API.
This documentation is specific to how Parameters extends the normal Python dictionary API. For documentation about the Python dictionary API, please checkout their official page here.
Example creating duplicate parameters:
>>> params = Parameters() >>> for value in range(3): ... params.add('myParam', value) ... Parameters([['myParam', 0], ['myParam', 1], ['myParam', 2]])
What NOT to do:
>>> params = Parameters() >>> for doh in range(3): ... params['homer'] = doh ... >>> params Parameters([['homer', 2], ['homer', 2], ['homer', 2]])
Iterating Parameters to build a query string:
>>> query = [] >>> params = Parameters(one=1, two=2) >>> for name, value in params.items(): ... query.append('%s=%s' % (name, value)) ... >>> query_str = '&'.join(query) >>> query_str 'one=1&two=2'
Parameters: - args (List, Tuple, or Dictionary) – Data to initialize the Parameters object with.
- kwargs (Dictionary) – Data to initialize the Parameters object with.

iiqtools.iiqtools_tar_to_zip¶
This script converts the format of datastore exports (not the CSV exports) from tar to zip. In InsightIQ 4.1, the format was changed to fix bug 162840, in which an attempt to import a large datastore export would time out. The only change to the exported data is the format. So to use an export from an older instance (before 4.1) all you have to convert the format. In other words, the data is still the same, it’s just a different compression format in InsightIQ 4.1.

Patching InsightIQ¶
This section explains how the patching mechanism works and how to create new patches for InsightIQ. This section is indented for source code contributors.
If you’re looking for documentation about install/uninstall patches, please checkout the Scripts section.
How patching works¶
Where patches are stored¶
The patching mechanism creates a directory under the installation path of the
InsightIQ source code. For example, if you deploy a new OVA
of InsightIQ 4.1.1, the installation path is
/usr/share/isilon/lib/python2.7/site-packages/insightiq
. The directory created
is named patches
, for obvious reasons. The patches
directory contains subdirectories;
one for each patch currently installed.
The reason for putting the patches
directory under the InsightIQ source code
is it simplifies upgrades. When you ask the patching mechanism “what patches are
currently installed” after an upgrade, it’ll always report that no patches are
installed. In otherwords, upgrading InsightIQ removes all patches. There’s no way
to avoid this; Python will overwrite the installation directory when upgrading
the InsightIQ package.
Example file structure before InsightIQ upgrade:
insightiq
\patches
\patch-1234
\patch-598
\config
\core
features.py
Example file structure after InsightIQ upgrade:
insightiq
\config
\core
features.py
This simplifies upgrades because we A) don’t have to try an “re-apply” a patch after an upgrade, or B) update our list of installed patches after an upgrade.
Specific patch directory contents¶
Lets say we have patch-1234 installed. The directory created (which is used to reference the patch) contains the following:
\patch-1234
meta.ini
README.txt
\originals
The meta.ini
and README.txt
are defined in the next section, and come from the
tar patch file. The directory originals
contains backup copies of the original
source files. When you install a patch, the patching tool creates these backups
to enable us to uninstall the patch. Within that directory, you’ll see some rather
long file names:
\originals
insightiq___controllers___security.py
The triple-underbars ___
are used to replace the forward slash normally associated
with a file system path. A triple-underbar is used instead of a single-underbar
because it’s common for a Python source file to contain a single-underbar.
What’s in a patch¶
A patch for InsightIQ is a tar file consisting of the following files:
- README.txt
- A description of the patch. This must always include the bug number for the issue that requires patching.
- meta.ini
- A config file that defines what source files are getting patched, and what versions of InsightIQ the patch works with.
- PATCHED_FILE
- The patched source file, where PATCHED_FILE is actually the name of the source file. There can be as many as these files as needed for the patch.
Within the tar file, these files must be stored in a directory that names the patch following the convention of patch-PATCH_NUMBER, where PATCH_NUMBER is the actual number used to identify the patch for Isilon. In other words, if you unfurl the patch tar file, a directory with the patch files is written to your file system.
Example of patch file contents:
README.txt
meta.ini
insightiq/controllers/security.py
The meta.ini¶
The format is your standard INI file,
with the headings info
, version
and files
.
The info
heading has two keys, name
which is the name of the patch, and
bug
which is the number for the associated bug that is being patched.
The versions
heading has two keys, minimum
and maximum
, and as you’ve
likely guessed, define the oldest and newest versions of InsightIQ that the patch
applies to.
The files
heading defines what files are being patched, and can have as many
keys as necessary. The key names should be the location of the original source
file (relative to the installation directory), and the key values are the md5
hash of that original source file. Why are we including md5 hashes? To avoid
installing patches that clobber (i.e. patch B overwrites the same file as patch A).
Example meta.ini:
[info]
name = patch-1234
bug = 156986
[version]
minimum = 4.1.0
maximum = 4.1.1
[files]
insightiq/controllers/security.py = 56266031a30cab220f56ee43b4159ded
Note
Version values are inclusive. If your patch only applies to one specific
release, both minimum
and maximum
should have the same value.
Making a patch¶
There are the steps to create a patch for a single source file. In this example, we are patching insightiq/controllers/security.py
Create a directory for the patch:
$ mkdir patch-1234
Copy your README.txt and meta.ini files into the directory made in step 1:
$ cp README.txt meta.ini patch-1234
Create all subdirectories for the source file paths:
$ mkdir -p patch-1234/insightiq/controllers
# Copy the patched files unto their respective locations::
$ cp security.py patch-1234/insightiq/controllers/
Create the tgz file:
$ cd patch-1234 && tar -zcvf insightiq-patch-1234.tgz *
