By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public 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. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

Such files also make also prefectly valid import candidates: + +```json +{ + "json1.example.com": { + "host": "json1.example.com", + "address": "127.0.0.1", + "location": "HQ", + "groups": [ "Linux Servers" ] + }, + "json2.example.com": { + "host": "json2.example.com", + "address": "127.0.0.2", + "location": "HQ", + "groups": [ "Windows Servers", "Lab" ] + } +} +``` + +Microsoft Excel +--------------- + +XSLX, the Microsoft Excel 2007+ format is supported since v1.1.0. + + +XML - Extensible Markup Language +-------------------------------- + +When working with [XML](https://en.wikipedia.org/wiki/XML) please try to ship +simple files as shown in the following example. We'd love to add more features +like better attribute support or [XPath](https://en.wikipedia.org/wiki/XPATH)- +based filters. In case you need such, please let us know and ship some exmple +data, helping us to better understand your requirements! + +### Simple XML example + +```xml +<?xml version="1.0" encoding="UTF-8" ?> +<hosts> + <host> + <name>xml1</name> + <address>127.0.0.1</address> + </host> + <host> + <name>xml2</name> + <address>127.0.0.2</address> + </host> +</hosts> +``` + + +YAML (Ain't Markup Language) +---------------------------- + +[YAML](https://en.wikipedia.org/wiki/YAML) is all but simple and well defined, +it allows you to write the same data in various ways. In case you opt for it +you might have your reasons and should already be familiar with how to generate +such files. + +### Simple YAML example + +So, let's start with a simple example: + +```yaml +--- +- host: "yaml1.example.com" + address: "127.0.0.1" + location: "HQ" +- host: "yaml2.example.com" + address: "127.0.0.2" + location: "HQ" +- host: "yaml3.example.com" + address: "127.0.0.3" + location: "HQ" +``` + +### Advanced YAML example + +People who think that NoSQL solves all there data problems tend to believe that +YAML solve all their config problems. So, YAML is pretty hip and widely used +among tools in hyped niches such as configuration management. I'll pick [Puppet](https://puppet.com/) +as an example, but this might work in a similar way for many other tools. + +Instead of a single YAML file I have to deal with a directory full of files in +this case. Our [Import Source documentation](03-ImportSource.md) already shows +how to configure such, here you can see part of such a file: + +```yaml +--- !ruby/object:Puppet::Node::Facts + name: foreman.localdomain + values: + architecture: x86_64 + timezone: CEST + kernel: Linux + system_uptime: "{\x22seconds\x22=>5415, \x22hours\x22=>1, \x22days\x22=>0, \x22uptime\x22=>\x221:30 hours\x22}" + domain: localdomain + virtual: kvm + is_virtual: "true" + hardwaremodel: x86_64 + operatingsystem: CentOS + facterversion: "2.4.6" + filesystems: xfs + fqdn: foreman.localdomain + hardwareisa: x86_64 + hostname: foreman +``` + +If this looks foreign to you don't worry, most similar constructs are handled in +a smooth way by the underlying YAML parser. + diff --git a/doc/screenshot/fileshipper/01_fileshipper-imports-overview.png b/doc/screenshot/fileshipper/01_fileshipper-imports-overview.png Binary files differnew file mode 100644 index 0000000..4a10487 --- /dev/null +++ b/doc/screenshot/fileshipper/01_fileshipper-imports-overview.png diff --git a/doc/screenshot/fileshipper/02_fileshipper-add-importsource.png b/doc/screenshot/fileshipper/02_fileshipper-add-importsource.png Binary files differnew file mode 100644 index 0000000..8bfbc15 --- /dev/null +++ b/doc/screenshot/fileshipper/02_fileshipper-add-importsource.png diff --git a/doc/screenshot/fileshipper/03_fileshipper-choose-format.png b/doc/screenshot/fileshipper/03_fileshipper-choose-format.png Binary files differnew file mode 100644 index 0000000..47fa9b6 --- /dev/null +++ b/doc/screenshot/fileshipper/03_fileshipper-choose-format.png diff --git a/doc/screenshot/fileshipper/04_fileshipper-choose-basedir.png b/doc/screenshot/fileshipper/04_fileshipper-choose-basedir.png Binary files differnew file mode 100644 index 0000000..a3258e3 --- /dev/null +++ b/doc/screenshot/fileshipper/04_fileshipper-choose-basedir.png diff --git a/doc/screenshot/fileshipper/05_fileshipper-csv-details.png b/doc/screenshot/fileshipper/05_fileshipper-csv-details.png Binary files differnew file mode 100644 index 0000000..9936e78 --- /dev/null +++ b/doc/screenshot/fileshipper/05_fileshipper-csv-details.png diff --git a/doc/screenshot/fileshipper/06_fileshipper-choose-file.png b/doc/screenshot/fileshipper/06_fileshipper-choose-file.png Binary files differnew file mode 100644 index 0000000..e20ba49 --- /dev/null +++ b/doc/screenshot/fileshipper/06_fileshipper-choose-file.png diff --git a/doc/screenshot/fileshipper/07_fileshipper-whole-directory.png b/doc/screenshot/fileshipper/07_fileshipper-whole-directory.png Binary files differnew file mode 100644 index 0000000..4f66c1c --- /dev/null +++ b/doc/screenshot/fileshipper/07_fileshipper-whole-directory.png diff --git a/library/Fileshipper/ProvidedHook/Director/ImportSource.php b/library/Fileshipper/ProvidedHook/Director/ImportSource.php new file mode 100644 index 0000000..c0d5ab5 --- /dev/null +++ b/library/Fileshipper/ProvidedHook/Director/ImportSource.php @@ -0,0 +1,613 @@ +<?php + +namespace Icinga\Module\Fileshipper\ProvidedHook\Director; + +use DirectoryIterator; +use Icinga\Application\Config; +use Icinga\Exception\ConfigurationError; +use Icinga\Exception\IcingaException; +use Icinga\Module\Director\Exception\JsonException; +use Icinga\Module\Director\Hook\ImportSourceHook; +use Icinga\Module\Director\Web\Form\QuickForm; +use Icinga\Module\Fileshipper\Xlsx\Workbook; +use RuntimeException; +use Symfony\Component\Yaml\Yaml; + +class ImportSource extends ImportSourceHook +{ + protected $db; + + protected $haveSymfonyYaml; + + public function getName() + { + return 'Import from files (fileshipper)'; + } + + /** + * @return object[] + * @throws ConfigurationError + * @throws IcingaException + */ + public function fetchData() + { + $basedir = $this->getSetting('basedir'); + $filename = $this->getSetting('file_name'); + $format = $this->getSetting('file_format'); + + if ($filename === '*') { + return $this->fetchFiles($basedir, $format); + } + + return (array) $this->fetchFile($basedir, $filename, $format); + } + + /** + * @return array + * @throws ConfigurationError + * @throws IcingaException + */ + public function listColumns() + { + return array_keys((array) current($this->fetchData())); + } + + /** + * @param QuickForm $form + * @return \Icinga\Module\Director\Forms\ImportSourceForm|QuickForm + * @throws \Zend_Form_Exception + */ + public static function addSettingsFormFields(QuickForm $form) + { + $form->addElement('select', 'file_format', array( + 'label' => $form->translate('File format'), + 'description' => $form->translate( + 'Available file formats, usually CSV, JSON, YAML and XML.
