1. ABOUT THIS RELEASE
   ==================
Thank you for downloading the eleventh packaged release of iTop.
This version is mostly a maintenance release that fixes a few bugs of iTop 1.2.

A wiki is available: https://sourceforge.net/apps/mediawiki/itop/index.php?title=ITop_Documentation
Additional documentation can be downloaded from there:
 - User guide
 - Administrator guide
 - Customization guide
 - Implementation guide
Wiki articles complete the documentation for advanced/specific concerns.


iTop is released under the GPL (v3) license. (Check license.txt in this directory).
The source code of iTop can be found on SourceForge: http://itop.sourceforge.net

1.1 What's new?
    ---------------------------
This version mostly consists in bug fixes for iTop 1.2, however there are a few new features:

- Better display of the impact analysis view: Allows to filter the classes of objects displayed in the
  graphical view. The view now resizes to fit the window of your browser.

- Query phrase book: create, test and store your OQL queries in the "Query Phrasebook" for an easy export
  via the "Export" menu, without the limitation of the URL length in Excel web queries ! A new export format
  "spreadsheet" has been added, specifically for running as Excel web queries (dates are split between date and time)

- Enhanced data synchronization:
  - For performing huge synchronizations with little memory (despite PHP's memory leaks), the execution of the data
    synchronization (in CLI mode only) can be run by chunk of x elements by specifying --max_chunk_size=x on the
    command line to synchro_import.php or synchro_exec.php. Try to set this value to 1000 to run with 128 MB of memory.
    As of now, there is no easy mean to check wether the execution has been split or not, and to evaluate the real benefit of this feature.
	 To do this, you will have to look into the database, in table priv_sync_log. The column memory_usage_peak gives you the maximum amount of memory used throughout the whole execution.  
  - When an (optional) external key cannot be reconciled, log a warning on the replica. the replicas containing a
    warning are then processed everytime in case the ext key changes.
  - Also improved the search/display of replicas for an easier troubleshooting of the synchronization.


1.2 Should I upgrade to 1.2.1?
    ---------------------------
Considering that there more than 20 bug fixes and very few new features we recommended you to upgrade
to this new version. Especially if you are using the data synchronization with big sets of data, you can benefit
from the new "chunk" mode by just adding a parameter to the command line !

2. INSTALLATION
   ============

2.1. Requirements
     ------------
Server configuration:
iTop is based on the AMP (Apache / MySQL / PHP) platform and requires PHP 5.2 and
MySQL 5. The installation of iTop does not require any command line access to the
server. The only operations required to install iTop are: copying the files to the
server and browsing web pages. iTop can be installed on Apache and IIS.

End-user configuration:
Although iTop should work with most modern web browsers, the application has been
tested mostly with Firefox 3, IE8, IE9, Safari 5 and Chrome. iTop was designed for
at least a 1024x768 screen resolution. For the graphical view of the impact analysis,
Flash version 8 or higher is required.

2.2. Install procedure
     -----------------
1) Make sure that you have a properly configured instance of Apache/PHP running
2) Unpack the files contained in the zipped package, and copy the content of the "web"
directory in a directory served by your web server.
3) Point your web browser to the URL corresponding to the directory where the files
have been unpackaged and follow the indications on the screen.

Note:
iTop uses MySQL with the InnoDB engine. If you are running on Linux and if the setup is
very slow with the hard drive spinning a lot, try to set the following value in the my.cnf
configuration file (usually located at /etc/mysql/my.cnf):

innodb_flush_method = O_DSYNC

On some systems you'll see a 5 to 10 times performance boost for writing data into
the MySQL database !

2.3. CRON.PHP
     --------
The following features will require the activation of CRON.PHP:
 - asynchronous emails. By default, this option is disabled. To enable it, set 'email_asynchronous' to 1 in the configuration file.
 - check ticket SLA. Tickets reaching the limits will be passed into Escalation TTO/TTR states.

More information into the Wiki: https://sourceforge.net/apps/mediawiki/itop/index.php?title=Cron.php

2.4. Migrating from 1.0, 1.0.1, 1.0.2, 1.1 or 1.2
     --------------------------------------------
You can simply overwrite the files from the previous version with the new ones but we recommend that you copy the files of the new version to new directory.
After installing the files, you MUST run the setup by
1) Marking the file config-itop.php as read-write for the web server
2) Poiting you web browser to http://<your_itop>/setup
The updgrade will modify the database schema. Be aware that this new schema is not compatible with the previous versions of iTop.

If you are executing the upgrade on a production instance of iTop, it is a good practice to make a backup of the database and the configuration file (config-itop.php) prior to running the upgrade.

Step by step instructions:
1) Unpack the files contained in the zipped package, and copy the content of the "web"
directory in a directory served by your web server.
2) Point your web browser to the URL corresponding to the directory where the files
have been unpackaged.
3) Select "Upgrade an existing iTop instance"
4) Follow the instructions.

5) If you were using tickets: CheckSLAForTickets.php (from 1.0 up to 1.0.2) has been deprecated in favour of cron.php - see section 2.3.


2.5. Migrating from 0.9
     ------------------
Depending on your current situation, there are several possible migration paths.
Please refer to the migration guide available at http://www.combodo.com/itopdocumentation.

Localization
------------
No big changes in localization for this release.

More information on the localization (completion progress, how to contribute) here:
http://www.combodo.com/itop-localization/

Minor changes
-------------
Automatic synchro of CAS/LDAP users: it is possible to have iTop automatically create the user record when an authorized user connects through CAS
 - Use the default language when creating a new user from CAS
 - Support patterns for casMemberof

Better error handling in case of OQL error in the audit page, now the error is properly trapped and indicates which query is the cuase of the error.

Added a link to a favicon (icon in the browser's bar and tab)

Allow a module to restrict the access to a given menu/group by redeclaring the menu with restricted rights. All rights are combined with the AND operator.

Bugs fixed
----------
The complete list of active tickets can be reviewed at http://sourceforge.net/apps/trac/itop/report/1

#494 It seems that PHPSoap does not understand the <wsdl:documentation> tag, let's put them as comments
#493 Incorrect display of Users' Grant Matrix
#487 Resizable text areas disappeared when located on the second tab !
#486 Fixed SQL dashboards limitations
#485 Export.php improved for integration into Excel / web queries (bug with IIS/HTTPS, limitation on the size of the OQL)
     Export for MS Excel web queries: format=spreadsheet Improved the end-user experience with Excel and the web queries (added a phrasebook)
     + link to test the OQL attributes (query phrasebook or email actions, etc.) including the handlink of query arguments)
     + fixed wrong prototypes for a few implementations of GetBareProperties()
#484 Fixed issue with IIS ("Wrong password" at first prompt)
#482 OpenSearch (integration with your browser's search bar) was broken.
#482 The setting 'min_autocomplete_chars' was not taken into account
#480 The 'min_autocomplete_chars' settings was not taken into account.
#478 Fixed issue in the audit: the results are wrong whenever an organization is selected
#477 Could not specify more than one reconciliation key (regression) + took the opportunity to enhance protection against XSS injection (using column names in the data)
#473 Could not load NW interfaces (reconciliation issue) - merged from trunk

Other bugs not listed in Trac:
Security issue: the attachments were visible by anybody (by forming URLs manually), whatever the allowed organizations. The change requires the execution of the setup/migration procedure.
Apply the AllowedValues constraints(as default values)  when selecting elements via the "magnifier" button or creating an new element via the "plus" button.
Paginated lists were broken in the Impact Analysis "List" tab
Incorrectly appending a parameter ?version= to linked scripts already containing a parameter in their URL, also changed the parameter name to 'itopversion' to avoid collisions
Always apply the AllowedValues constraints(as default values)  when selecting elements via the "magnifier" button or creating an new element via the "plus" button... also make sure that allowed values is enforced
When searching objects to add to the current object (when managing n:n relationships), set the default search params in order to stay in the current silo.
Fixed issue: nobody in the list of persons to notify for portal users (security takes precedence)
In the setup: increased Suhosin minimum value for get_max_value to 2048 due to a bug seen on some installations
