However, starting with pip 1.5, we began to replace code that was +implemented inside of pip with reusable libraries from PyPI. This brought the +typical benefits of reusing libraries instead of reinventing the wheel like +higher quality and more battle tested code, centralization of bug fixes +(particularly security sensitive ones), and better/more features for less work. + +However, there are several issues with having dependencies in the traditional +way (via ``install_requires``) for pip. These issues are: + +* **Fragility.** When pip depends on another library to function then if for + whatever reason that library either isn't installed or an incompatible + version is installed then pip ceases to function. This is of course true for + all Python applications, however for every application *except* for pip the + way you fix it is by re-running pip. Obviously, when pip can't run, you can't + use pip to fix pip, so you're left having to manually resolve dependencies and + installing them by hand. + +* **Making other libraries uninstallable.** One of pip's current dependencies is + the ``requests`` library, for which pip requires a fairly recent version to run. + If pip depended on ``requests`` in the traditional manner, then we'd either + have to maintain compatibility with every ``requests`` version that has ever + existed (and ever will), OR allow pip to render certain versions of ``requests`` + uninstallable. (The second issue, although technically true for any Python + application, is magnified by pip's ubiquity; pip is installed by default in + Python, in ``pyvenv``, and in ``virtualenv``.) + +* **Security.** This might seem puzzling at first glance, since vendoring + has a tendency to complicate updating dependencies for security updates, + and that holds true for pip. However, given the *other* reasons for avoiding + dependencies, the alternative is for pip to reinvent the wheel itself. + This is what pip did historically. It forced pip to re-implement its own + HTTPS verification routines as a workaround for the Python standard library's + lack of SSL validation, which resulted in similar bugs in the validation routine + in ``requests`` and ``urllib3``, except that they had to be discovered and + fixed independently. Even though we're vendoring, reusing libraries keeps pip + more secure by relying on the great work of our dependencies, *and* allowing for + faster, easier security fixes by simply pulling in newer versions of dependencies. + +* **Bootstrapping.** Currently most popular methods of installing pip rely + on pip's self-contained nature to install pip itself. These tools work by bundling + a copy of pip, adding it to ``sys.path``, and then executing that copy of pip. + This is done instead of implementing a "mini installer" (to reduce duplication); + pip already knows how to install a Python package, and is far more battle-tested + than any "mini installer" could ever possibly be. + +Many downstream redistributors have policies against this kind of bundling, and +instead opt to patch the software they distribute to debundle it and make it +rely on the global versions of the software that they already have packaged +(which may have its own patches applied to it). We (the pip team) would prefer +it if pip was *not* debundled in this manner due to the above reasons and +instead we would prefer it if pip would be left intact as it is now. The one +exception to this, is it is acceptable to remove the +``pip/_vendor/requests/cacert.pem`` file provided you ensure that the +``ssl.get_default_verify_paths().cafile`` API returns the correct CA bundle for +your system. This will ensure that pip will use your system provided CA bundle +instead of the copy bundled with pip. + +In the longer term, if someone has a *portable* solution to the above problems, +other than the bundling method we currently use, that doesn't add additional +problems that are unreasonable then we would be happy to consider, and possibly +switch to said method. This solution must function correctly across all of the +situation that we expect pip to be used and not mandate some external mechanism +such as OS packages. + + +Modifications +============= + +* ``setuptools`` is completely stripped to only keep ``pkg_resources`` +* ``pkg_resources`` has been modified to import its dependencies from ``pip._vendor`` +* ``packaging`` has been modified to import its dependencies from ``pip._vendor`` +* ``html5lib`` has been modified to import six from ``pip._vendor`` and + to prefer importing from ``collections.abc`` instead of ``collections``. +* ``CacheControl`` has been modified to import its dependencies from ``pip._vendor`` +* ``requests`` has been modified to import its other dependencies from ``pip._vendor`` + and to *not* load ``simplejson`` (all platforms) and ``pyopenssl`` (Windows). + + +Automatic Vendoring +=================== + +Vendoring is automated via the ``vendoring`` tool from the content of +``pip/_vendor/vendor.txt`` and the different patches in +``tools/automation/vendoring/patches``. +Launch it via ``vendoring sync . -v`` (requires ``vendoring>=0.2.2``). + + +Debundling +========== + +As mentioned in the rationale, we, the pip team, would prefer it if pip was not +debundled (other than optionally ``pip/_vendor/requests/cacert.pem``) and that +pip was left intact. However, if you insist on doing so, we have a +semi-supported method (that we don't test in our CI) and requires a bit of +extra work on your end in order to solve the problems described above. + +1. Delete everything in ``pip/_vendor/`` **except** for + ``pip/_vendor/__init__.py``. + +2. Generate wheels for each of pip's dependencies (and any of their + dependencies) using your patched copies of these libraries. These must be + placed somewhere on the filesystem that pip can access (``pip/_vendor`` is + the default assumption). + +3. Modify ``pip/_vendor/__init__.py`` so that the ``DEBUNDLED`` variable is + ``True``. + +4. Upon installation, the ``INSTALLER`` file in pip's own ``dist-info`` + directory should be set to something other than ``pip``, so that pip + can detect that it wasn't installed using itself. + +5. *(optional)* If you've placed the wheels in a location other than + ``pip/_vendor/``, then modify ``pip/_vendor/__init__.py`` so that the + ``WHEEL_DIR`` variable points to the location you've placed them. + +6. *(optional)* Update the ``pip_self_version_check`` logic to use the + appropriate logic for determining the latest available version of pip and + prompt the user with the correct upgrade message. + +Note that partial debundling is **NOT** supported. You need to prepare wheels +for all dependencies for successful debundling. diff --git a/fetchcode/vcs/pip/_vendor/__init__.py b/fetchcode/vcs/pip/_vendor/__init__.py new file mode 100644 index 00000000..8a3471b6 --- /dev/null +++ b/fetchcode/vcs/pip/_vendor/__init__.py @@ -0,0 +1,114 @@ +""" +pip._vendor is for vendoring dependencies of pip to prevent needing pip to +depend on something external. + +Files inside of pip._vendor should be considered immutable and should only be +updated to versions from upstream. +""" +from __future__ import absolute_import + +import glob +import os.path +import sys + +# Downstream redistributors which have debundled our dependencies should also +# patch this value to be true.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +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 and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, 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 library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete 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 distribute a copy of this License along with the +Library. + + 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 Library or any portion +of it, thus forming a work based on the Library, 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) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +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 Library, 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 Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you 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. + + If distribution of 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 satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be 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. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library 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. + + 9. 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 Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +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 with +this License. + + 11. 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 Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library 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 Library. + +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. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library 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. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser 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 Library +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 Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +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 + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "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 +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. 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 LIBRARY 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 +LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library.

Logical Hebrew ?? +# +# Both "ISO" charsets use a completely identical set of code points, whereas +# "windows-1255" and "x-mac-hebrew" are two different proper supersets of +# these code points. windows-1255 defines additional characters in the range +# 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific +# diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6. +# x-mac-hebrew defines similar additional code points but with a different +# mapping. +# +# As far as an average Hebrew text with no diacritics is concerned, all four +# charsets are identical with respect to code points. Meaning that for the +# main Hebrew alphabet, all four map the same values to all 27 Hebrew letters +# (including final letters). +# +# The dominant difference between these charsets is their directionality. +# "Visual" directionality means that the text is ordered as if the renderer is +# not aware of a BIDI rendering algorithm. The renderer sees the text and +# draws it from left to right. The text itself when ordered naturally is read +# backwards. A buffer of Visual Hebrew generally looks like so: +# "[last word of first line spelled backwards] [whole line ordered backwards +# and spelled backwards] [first word of first line spelled backwards] +# [end of line] [last word of second line] ... etc' " +# adding punctuation marks, numbers and English text to visual text is +# naturally also "visual" and from left to right. +# +# "Logical" directionality means the text is ordered "naturally" according to +# the order it is read. It is the responsibility of the renderer to display +# the text from right to left. A BIDI algorithm is used to place general +# punctuation marks, numbers and English text in the text. +# +# Texts in x-mac-hebrew are almost impossible to find on the Internet. From +# what little evidence I could find, it seems that its general directionality +# is Logical. +# +# To sum up all of the above, the Hebrew probing mechanism knows about two +# charsets: +# Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are +# backwards while line order is natural. For charset recognition purposes +# the line order is unimportant (In fact, for this implementation, even +# word order is unimportant). +# Logical Hebrew - "windows-1255" - normal, naturally ordered text. +# +# "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be +# specifically identified. +# "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew +# that contain special punctuation marks or diacritics is displayed with +# some unconverted characters showing as question marks. This problem might +# be corrected using another model prober for x-mac-hebrew. Due to the fact +# that x-mac-hebrew texts are so rare, writing another model prober isn't +# worth the effort and performance hit. +# +#### The Prober #### +# +# The prober is divided between two SBCharSetProbers and a HebrewProber, +# all of which are managed, created, fed data, inquired and deleted by the +# SBCSGroupProber. The two SBCharSetProbers identify that the text is in +# fact some kind of Hebrew, Logical or Visual. The final decision about which +# one is it is made by the HebrewProber by combining final-letter scores +# with the scores of the two SBCharSetProbers to produce a final answer. +# +# The SBCSGroupProber is responsible for stripping the original text of HTML +# tags, English characters, numbers, low-ASCII punctuation characters, spaces +# and new lines. It reduces any sequence of such characters to a single space. +# The buffer fed to each prober in the SBCS group prober is pure text in +# high-ASCII. +# The two SBCharSetProbers (model probers) share the same language model: +# Win1255Model. +# The first SBCharSetProber uses the model normally as any other +# SBCharSetProber does, to recognize windows-1255, upon which this model was +# built. The second SBCharSetProber is told to make the pair-of-letter +# lookup in the language model backwards. This in practice exactly simulates +# a visual Hebrew model using the windows-1255 logical Hebrew model. +# +# The HebrewProber is not using any language model. All it does is look for +# final-letter evidence suggesting the text is either logical Hebrew or visual +# Hebrew. Disjointed from the model probers, the results of the HebrewProber +# alone are meaningless. HebrewProber always returns 0.00 as confidence +# since it never identifies a charset by itself. Instead, the pointer to the +# HebrewProber is passed to the model probers as a helper "Name Prober". +# When the Group prober receives a positive identification from any prober, +# it asks for the name of the charset identified. If the prober queried is a +# Hebrew model prober, the model prober forwards the call to the +# HebrewProber to make the final decision. In the HebrewProber, the +# decision is made according to the final-letters scores maintained and Both +# model probers scores.

HISTORY OF THE SOFTWARE +========================== + +contextlib2 is a derivative of the contextlib module distributed by the PSF +as part of the Python standard library. According, it is itself redistributed +under the PSF license (reproduced in full below). As the contextlib module +was added only in Python 2.5, the licenses for earlier Python versions are +not applicable and have not been included. + +Python was created in the early 1990s by Guido van Rossum at Stichting +Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands +as a successor of a language called ABC. Guido remains Python's +principal author, although it includes many contributions from others. + +In 1995, Guido continued his work on Python at the Corporation for +National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) +in Reston, Virginia where he released several versions of the +software. + +In May 2000, Guido and the Python core development team moved to +BeOpen.com to form the BeOpen PythonLabs team. In October of the same +year, the PythonLabs team moved to Digital Creations (now Zope +Corporation, see http://www.zope.com). In 2001, the Python Software +Foundation (PSF, see http://www.python.org/psf/) was formed, a +non-profit organization created specifically to own Python-related +Intellectual Property. Zope Corporation is a sponsoring member of +the PSF. + +All Python releases are Open Source (see http://www.opensource.org for +the Open Source Definition). Historically, most, but not all, Python +releases have also been GPL-compatible; the table below summarizes +the various releases that included the contextlib module. + + Release Derived Year Owner GPL- + from compatible?

HISTORY OF THE SOFTWARE +========================== + +Python was created in the early 1990s by Guido van Rossum at Stichting +Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands +as a successor of a language called ABC. Guido remains Python's +principal author, although it includes many contributions from others. + +In 1995, Guido continued his work on Python at the Corporation for +National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) +in Reston, Virginia where he released several versions of the +software. + +In May 2000, Guido and the Python core development team moved to +BeOpen.com to form the BeOpen PythonLabs team. In October of the same +year, the PythonLabs team moved to Digital Creations (now Zope +Corporation, see http://www.zope.com). In 2001, the Python Software +Foundation (PSF, see http://www.python.org/psf/) was formed, a +non-profit organization created specifically to own Python-related +Intellectual Property. Zope Corporation is a sponsoring member of +the PSF. + +All Python releases are Open Source (see http://www.opensource.org for +the Open Source Definition). Historically, most, but not all, Python +releases have also been GPL-compatible; the table below summarizes +the various releases. + + Release Derived Year Owner GPL- + from compatible?
