6. Appendixes

6.1. ChangeLog

6.1.1. Version 0.6.1

Release Date: May 12, 2010


  • QualityFITS plugin: added support for “single chip flat normalization”, which allows to compute a new normalisation based on independant chips. This is required to select the bad pixels from each chip in a consistant way. Important: please note that this feature requires to use QualityFITS 1.13.12 or higher.
  • QualityFITS results: displays grade’s comment next to grade letter
  • Added support for FITS keyword copying (+KEYWORD) in ingestion translation tables (ITTs)
  • Added support for automatic .head file generation to allow FITS image header keywords overriding
  • Added a can_change_custom_condor_req global permission to prevent users modifying their custom Condor requirement string
  • New report “List of all QualityFITS grades, with comments (HTML)”
  • New report “Advanced image report”
  • Added report description and thumbnail preview to reporting module
  • New MAINTENANCE mode for maintenance operations
  • Various performance improvements in production environment (by combining static Javascript and CSS files into single files and minifying their content)
  • New command line tool script/changeseeing.py to compute and store images pixel scale and reprocess all QualityFITS XML output results. Please see the Release Notes for more information
  • Clicking on your username (top-left corner) will popup information related to your active permission attributes
  • Data output directory: plugins append a random 8-chars string at the end of the data path to prevent results to be overridden by mistake
  • Post-processing: remote files not needed anymore at the end of processings are deleted

Bug fixes:

  • Processings will not fail anymore when working with re-ingested images
  • Ingestion: fixed bug during target hostname resolution
  • Image selector: stops loading and displays a user-friendly message when no images available (no ingestions at all)
  • QualityFITS results: hide “Image tags” block when image has no tags
  • QualityFITS results: fixed permission issue. Non-authorized users cannot access restricted results anymore
  • QualityFITS results: fixed counter value for already graded images
  • QualityFITS: fixed “list of all non graded images” report
  • QualityFITS: fixed broken “reprocess” button on the results page
  • QualityFITS: fixed psfex’s XML output parsing
  • Grading script: fixed custom comment issue
  • Processing history results: fixed a Server Error issue when resetting the search form
  • Path selector widget: fixed automatic path selection
  • Minor fixes


Please note that QualityFITS 1.13.12 or higher is required for this release to work properly.

Release Notes:

In order to upgrade from 0.6, please do the following:

  1. Make a backup of your database.

  2. A third file private_conf.py is now taken into account for Youpi’s configuration. Most of the content of the settings.py-dist that comes with the distribution has been moved to the new configuration file. The best (not the fastest) way to upgrade your settings.py file for this new release is to make a backup of it and copy the content of the latest settings.py-dist:

    $ cp settings.py settings.py.orig
    $ cp settings.py-dist settings.py

    Now, just replace the FIXME directives in your newly created settings.py with the working values available in your settings.py.orig.


    Although this can be a tedious task, it is the more secure way to ensure your settings.py file is up-to-date with the latest settings.py-dist file provided in the source distribution. Future upgrades will be easier since all core parts of the configuration have moved to the private_conf.py file. Any new change will be directly committed to the file without requiring anymore admin action on application upgrade.

  1. The database structure has changed. Just tell Youpi to inspect your installation and upgrade the database if needed:

    $ python manage.py checksetup

    Everytime the database structure has to be updated, you will be prompted for confirmation:

    Are you sure you want to execute the evolutions?
    Type 'yes' to continue, or 'no' to cancel:

    If you have made a database backup, you can safely answer: yes.

  2. CSS and Javascript file minification is accomplished using Yahoo’s YUI Java compressor. In order to use it with Youpi, make sure that Java is installed on your system and download the YUI compressor tool. Then, add the following line to your settings.py file or (preferred) local_conf.py, replacing the absolute path to the JAR archive accordingly:

    COMPRESS_YUI_BINARY = "java -jar /path/to/yuicompressor-2.x.x.jar"


    If, for any reason, you don’t want to use the YUI compressor or Java at all, you can safely disable the terapix.compress application by adding a COMPRESS = False line in your settings file. This setting will disable minification.


    We recommand using minification techniques when deploying the application in a production environment. Although the included django-compress module works without using the YUI compressor (using its own internal tools), the YUI compressor will generally give better results.

  3. (This step is optional) Now that everything is set up, you can generate the minified static files from the command line (otherwise they get generated automatically on-the-fly):

    $ python manage.py synccompress
  1. (This step is optional) The database structure has been altered for this release. You may want to compute images pixel scale values or reprocess all QualityFITS XML results using the script/changeseeing.py script. Try a:

    $ python script/changeseeing.py -p -v

    to compute all images pixel scale, then:

    $ python script/changeseeing.py -q -v

    to reingest all successful QualityFITS XML results. Other options are available through the changeseeing.py -h command.


    Those two commands may take a long time to complete depending on the amount of information stored in your database.

6.1.2. Version 0.6

Release Date: January 28, 2010


  • Added support for Generic FITS image ingestion using translation tables (ITTs)
  • Added several global permissions in order to be able to define more restrictive user accounts
  • QualityFITS plugin: added an option to force exiting a QFits job immediately if the flat image is missing
  • Current user permissions are available on the “Preferences” page
  • Results page: added more search criteria; processing results can be searched by tags
  • Added new self-designed icon set (GUI)
  • Added a keyboard shortcut (Alt+Shift+g) for accessing the image grading page from the results page
  • New path tool script useful to display/alter important data paths stored in the database

Bug fixes:

  • Results page: fixed the “already graded images” counter’s value
  • Minor fixes

Release Notes:

In order to upgrade from 0.5.2, please do the following:

  1. Make a backup of your database.

  2. The database structure has changed. Just tell Youpi to inspect your installation and upgrade the database:

    $ python manage.py checksetup

Everytime the database structure has to be updated, you will be prompted for confirmation:

Are you sure you want to execute the evolutions?
Type 'yes' to continue, or 'no' to cancel:

If you have made a database backup, you can safely answer: yes.

6.1.3. Version 0.5.2

Release Date: November 28, 2009


  • Check setup script: handles database schema updates automatically; now handles default condor setup parameters
  • Core API related to Condor cluster management greatly improved
  • Monitoring Condor jobs from the “Active Monitoring” page is much faster
  • Plugin manager OOP design improved
  • Removed all parts related to preingestion step (no more needed)

Bug fixes:

  • Fixed processing cart issues (session related)
  • Fixed the “Software version check” feature
  • Swarp plugin: fixed final stack ingestion issues; fixed bug preventing swarp item cluster submission
  • Sextractor plugin: fixed bad weight image name in dual image mode; fixed a data path issue
  • All plugins: fixed bad XSL stylesheet URI handling

Release Notes:

In order to upgrade from 0.5.1, please do the following:


Following these steps in order is important. Please do not issue a checksetup command before step 4. The database structure has to be manually altered first (step 1).

  1. Make a backup of your database.

  2. Connect to your MySQL databsase and issue the following statements:

    $ python manage.py dbshell
    mysql> alter table youpi_image drop `QSOstatus`;
    mysql> alter table youpi_image add `is_validated` bool;
    mysql> update youpi_image set is_validated=1;
    mysql> alter table youpi_ingestion drop `check_QSO_status`;
    mysql> alter table youpi_ingestion add `is_validated` bool;
    mysql> update youpi_ingestion set is_validated=1;


    you have to do this upgrade manually when updating from version 0.5.1 to 0.5.2. Future database upgrades will be performed automatically using the “Django evolution” application activated at step 3.

  3. From the settings.py-dist file, copy the YOUPI_ACTIVE_PLUGINS variable into your settings.py or local_conf.py file:

    YOUPI_ACTIVE_PLUGINS = ('qualityfitsin', 'scamp', 'swarp', 'sextractor')
  4. Edit your settings.py file and add the line terapix.django_evolution to your INSTALLED_APPS variable so it looks like the following:

  5. Finally, let Youpi inspect your installation setup and tell the django-evolution application to make an initial snapshot of the database structure:

    $ python manage.py checksetup

6.1.4. Version 0.5.1

Release Date: September 30, 2009

First public release.

6.2. GNU Free Documentation License

Version:Version 1.3
Date:3 November 2008
Copyright:(C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

The purpose of this License is to make a manual, textbook, or other functional and useful document “free” in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.

This License is a kind of “copyleft”, which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.

We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.


This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The “Document”, below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as “you”. You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.

A “Modified Version” of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.

A “Secondary Section” is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document’s overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.

The “Invariant Sections” are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.

The “Cover Texts” are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.

A “Transparent” copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not “Transparent” is called “Opaque”.

Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.

The “Title Page” means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, “Title Page” means the text near the most prominent appearance of the work’s title, preceding the beginning of the body of the text.

The “publisher” means any person or entity that distributes copies of the Document to the public.

A section “Entitled XYZ” means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” of such a section when you modify the Document means that it remains a section “Entitled XYZ” according to this definition.

The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.


You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

You may also lend copies, under the same conditions stated above, and you may publicly display copies.


If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document’s license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.

If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.


You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

  1. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission.
  2. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement.
  3. State on the Title page the name of the publisher of the Modified Version, as the publisher.
  4. Preserve all the copyright notices of the Document.
  5. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.
  6. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.
  7. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document’s license notice.
  8. Include an unaltered copy of this License.
  9. Preserve the section Entitled “History”, Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.
  10. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the “History” section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission.
  11. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein.
  12. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles.
  13. Delete any section Entitled “Endorsements”. Such a section may not be included in the Modified Version.
  14. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in title with any Invariant Section.
  15. Preserve any Warranty Disclaimers.

If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version’s license notice. These titles must be distinct from any other section titles.

You may add a section Entitled “Endorsements”, provided it contains nothing but endorsements of your Modified Version by various parties–for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.


You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.

The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.

In the combination, you must combine any sections Entitled “History” in the various original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements”, and any sections Entitled “Dedications”. You must delete all sections Entitled “Endorsements”.


You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.


A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an “aggregate” if the copyright resulting from the compilation is not used to limit the legal rights of the compilation’s users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.

If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document’s Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.


Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.

If a section in the Document is Entitled “Acknowledgements”, “Dedications”, or “History”, the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.


You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License.

However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it.


The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.

Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License “or any later version” applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy’s public statement of acceptance of a version permanently authorizes you to choose that version for the Document.


“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site.

“CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization.

“Incorporate” means to publish or republish a Document, in whole or in part, as part of another Document.

An MMC is “eligible for relicensing” if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008.

The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing.

ADDENDUM: How to use this License for your documents

To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:

Copyright (c) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled “GNU Free Documentation License”.

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the “with...Texts.” line with this:

with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.

If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.

If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
