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. 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. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library 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.

The string + can also be modified in the post-extract call back. + **Bugs correction : + - PCLZIP_OPT_REMOVE_ALL_PATH was not working correctly + - Remove use of eval() and do direct call to callback functions + - Correct support of 64bits systems (Thanks to WordPress team) + + Version 2.8.1 : + - Move option PCLZIP_OPT_BY_EREG to PCLZIP_OPT_BY_PREG because ereg() is + deprecated in PHP 5.3. When using option PCLZIP_OPT_BY_EREG, PclZip will + automatically replace it by PCLZIP_OPT_BY_PREG. + + Version 2.8 : + - Improve extraction of zip archive for large files by using temporary files + This feature is working like the one defined in r2.7. + Options are renamed : PCLZIP_OPT_TEMP_FILE_ON, PCLZIP_OPT_TEMP_FILE_OFF, + PCLZIP_OPT_TEMP_FILE_THRESHOLD + - Add a ratio constant PCLZIP_TEMPORARY_FILE_RATIO to configure the auto + sense of temporary file use. + - Bug correction : Reduce filepath in returned file list to remove ennoying + './/' preambule in file path. + + Version 2.7 : + - Improve creation of zip archive for large files : + PclZip will now autosense the configured memory and use temporary files + when large file is suspected. + This feature can also ne triggered by manual options in create() and add() + methods. 'PCLZIP_OPT_ADD_TEMP_FILE_ON' force the use of temporary files, + 'PCLZIP_OPT_ADD_TEMP_FILE_OFF' disable the autosense technic, + 'PCLZIP_OPT_ADD_TEMP_FILE_THRESHOLD' allow for configuration of a size + threshold to use temporary files. + Using "temporary files" rather than "memory" might take more time, but + might give the ability to zip very large files : + Tested on my win laptop with a 88Mo file : + Zip "in-memory" : 18sec (max_execution_time=30, memory_limit=180Mo) + Zip "tmporary-files" : 23sec (max_execution_time=30, memory_limit=30Mo) + - Replace use of mktime() by time() to limit the E_STRICT error messages. + - Bug correction : When adding files with full windows path (drive letter) + PclZip is now working. Before, if the drive letter is not the default + path, PclZip was not able to add the file. + + Version 2.6 : + - Code optimisation + - New attributes PCLZIP_ATT_FILE_COMMENT gives the ability to + add a comment for a specific file. (Don't really know if this is usefull) + - New attribute PCLZIP_ATT_FILE_CONTENT gives the ability to add a string + as a file. + - New attribute PCLZIP_ATT_FILE_MTIME modify the timestamp associated with + a file. + - Correct a bug. Files archived with a timestamp with 0h0m0s were extracted + with current time + - Add CRC value in the informations returned back for each file after an + action. + - Add missing closedir() statement. + - When adding a folder, and removing the path of this folder, files were + incorrectly added with a '/' at the beginning. Which means files are + related to root in unix systems. Corrected. + - Add conditional if before constant definition. This will allow users + to redefine constants without changing the file, and then improve + upgrade of pclzip code for new versions. + + Version 2.5 : + - Introduce the ability to add file/folder with individual properties (file descriptor). + This gives for example the ability to change the filename of a zipped file. + . Able to add files individually + . Able to change full name + . Able to change short name + . Compatible with global options + - New attributes : PCLZIP_ATT_FILE_NAME, PCLZIP_ATT_FILE_NEW_SHORT_NAME, PCLZIP_ATT_FILE_NEW_FULL_NAME + - New error code : PCLZIP_ERR_INVALID_ATTRIBUTE_VALUE + - Add a security control feature. PclZip can extract any file in any folder + of a system. People may use this to upload a zip file and try to override + a system file. The PCLZIP_OPT_EXTRACT_DIR_RESTRICTION will give the + ability to forgive any directory transversal behavior. + - New PCLZIP_OPT_EXTRACT_DIR_RESTRICTION : check extraction path + - New error code : PCLZIP_ERR_DIRECTORY_RESTRICTION + - Modification in PclZipUtilPathInclusion() : dir and path beginning with ./ will be prepend + by current path (getcwd()) + + Version 2.4 : + - Code improvment : try to speed up the code by removing unusefull call to pack() + - Correct bug in delete() : delete() should be called with no argument. This was not + the case in 2.3. This is corrected in 2.4. + - Correct a bug in path_inclusion function. When the path has several '../../', the + result was bad. + - Add a check for magic_quotes_runtime configuration. If enabled, PclZip will + disable it while working and det it back to its original value. + This resolve a lots of bad formated archive errors. + - Bug correction : PclZip now correctly unzip file in some specific situation, + when compressed content has same size as uncompressed content. + - Bug correction : When selecting option 'PCLZIP_OPT_REMOVE_ALL_PATH', + directories are not any more created. + - Code improvment : correct unclosed opendir(), better handling of . and .. in + loops. + + + Version 2.3 : + - Correct a bug with PHP5 : affecting the value 0xFE49FFE0 to a variable does not + give the same result in PHP4 and PHP5 .... + + Version 2.2 : + - Try development of PCLZIP_OPT_CRYPT ..... + However this becomes to a stop. To crypt/decrypt I need to multiply 2 long integers, + the result (greater than a long) is not supported by PHP. Even the use of bcmath + functions does not help. I did not find yet a solution ...; + - Add missing '/' at end of directory entries + - Check is a file is encrypted or not. Returns status 'unsupported_encryption' and/or + error code PCLZIP_ERR_UNSUPPORTED_ENCRYPTION. + - Corrected : Bad "version need to extract" field in local file header + - Add private method privCheckFileHeaders() in order to check local and central + file headers. PclZip is now supporting purpose bit flag bit 3. Purpose bit flag bit 3 gives + the ability to have a local file header without size, compressed size and crc filled. + - Add a generic status 'error' for file status + - Add control of compression type. PclZip only support deflate compression method. + Before v2.2, PclZip does not check the compression method used in an archive while + extracting. With v2.2 PclZip returns a new error status for a file using an unsupported + compression method. New status is "unsupported_compression". New error code is + PCLZIP_ERR_UNSUPPORTED_COMPRESSION. + - Add optional attribute PCLZIP_OPT_STOP_ON_ERROR. This will stop the extract of files + when errors like 'a folder with same name exists' or 'a newer file exists' or + 'a write protected file' exists, rather than set a status for the concerning file + and resume the extract of the zip. + - Add optional attribute PCLZIP_OPT_REPLACE_NEWER. This will force, during an extract' the + replacement of the file, even if a newer version of the file exists. + Note that today if a file with the same name already exists but is older it will be + replaced by the extracted one. + - Improve PclZipUtilOption() + - Support of zip archive with trailing bytes. Before 2.2, PclZip checks that the central + directory structure is the last data in the archive. Crypt encryption/decryption of + zip archive put trailing 0 bytes after decryption. PclZip is now supporting this. + + Version 2.1 : + - Add the ability to abort the extraction by using a user callback function. + The user can now return the value '2' in its callback which indicates to stop the + extraction. For a pre call-back extract is stopped before the extration of the current + file. For a post call back, the extraction is stopped after. + - Add the ability to extract a file (or several files) directly in the standard output. + This is done by the new parameter PCLZIP_OPT_EXTRACT_IN_OUTPUT with method extract(). + - Add support for parameters PCLZIP_OPT_COMMENT, PCLZIP_OPT_ADD_COMMENT, + PCLZIP_OPT_PREPEND_COMMENT. This will create, replace, add, or prepend comments + in the zip archive. + - When merging two archives, the comments are not any more lost, but merged, with a + blank space separator. + - Corrected bug : Files are not deleted when all files are asked to be deleted. + - Corrected bug : Folders with name '0' made PclZip to abort the create or add feature. + + + Version 2.0 : + ***** Warning : Some new features may break the backward compatibility for your scripts. + Please carefully read the readme file. + - Add the ability to delete by Index, name and regular expression. This feature is + performed by the method delete(), which uses the optional parameters + PCLZIP_OPT_BY_INDEX, PCLZIP_OPT_BY_NAME, PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG. + - Add the ability to extract by regular expression. To extract by regexp you must use the method + extract(), with the option PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG + (depending if you want to use ereg() or preg_match() syntax) followed by the + regular expression pattern. + - Add the ability to extract by index, directly with the extract() method. This is a + code improvment of the extractByIndex() method. + - Add the ability to extract by name. To extract by name you must use the method + extract(), with the option PCLZIP_OPT_BY_NAME followed by the filename to + extract or an array of filenames to extract. To extract all a folder, use the folder + name rather than the filename with a '/' at the end. + - Add the ability to add files without compression. This is done with a new attribute + which is PCLZIP_OPT_NO_COMPRESSION. + - Add the attribute PCLZIP_OPT_EXTRACT_AS_STRING, which allow to extract a file directly + in a string without using any file (or temporary file). + - Add constant PCLZIP_SEPARATOR for static configuration of filename separators in a single string. + The default separator is now a comma (,) and not any more a blank space. + THIS BREAK THE BACKWARD COMPATIBILITY : Please check if this may have an impact with + your script. + - Improve algorythm performance by removing the use of temporary files when adding or + extracting files in an archive. + - Add (correct) detection of empty filename zipping. This can occurs when the removed + path is the same + as a zipped dir. The dir is not zipped (['status'] = filtered), only its content. + - Add better support for windows paths (thanks for help from manus@manusfreedom.com). + - Corrected bug : When the archive file already exists with size=0, the add() method + fails. Corrected in 2.0. + - Remove the use of OS_WINDOWS constant. Use php_uname() function rather. + - Control the order of index ranges in extract by index feature. + - Change the internal management of folders (better handling of internal flag). + + + Version 1.3 : + - Removing the double include check. This is now done by include_once() and require_once() + PHP directives. + - Changing the error handling mecanism : Remove the use of an external error library. + The former PclError...() functions are replaced by internal equivalent methods. + By changing the environment variable PCLZIP_ERROR_EXTERNAL you can still use the former library. + Introducing the use of constants for error codes rather than integer values. This will help + in futur improvment. + Introduction of error handling functions like errorCode(), errorName() and errorInfo(). + - Remove the deprecated use of calling function with arguments passed by reference. + - Add the calling of extract(), extractByIndex(), create() and add() functions + with variable options rather than fixed arguments. + - Add the ability to remove all the file path while extracting or adding, + without any need to specify the path to remove. + This is available for extract(), extractByIndex(), create() and add() functionS by using + the new variable options parameters : + - PCLZIP_OPT_REMOVE_ALL_PATH : by indicating this option while calling the fct. + - Ability to change the mode of a file after the extraction (chmod()). + This is available for extract() and extractByIndex() functionS by using + the new variable options parameters. + - PCLZIP_OPT_SET_CHMOD : by setting the value of this option. + - Ability to definition call-back options. These call-back will be called during the adding, + or the extracting of file (extract(), extractByIndex(), create() and add() functions) : + - PCLZIP_CB_PRE_EXTRACT : will be called before each extraction of a file. The user + can trigerred the change the filename of the extracted file. The user can triggered the + skip of the extraction. This is adding a 'skipped' status in the file list result value. + - PCLZIP_CB_POST_EXTRACT : will be called after each extraction of a file. + Nothing can be triggered from that point. + - PCLZIP_CB_PRE_ADD : will be called before each add of a file. The user + can trigerred the change the stored filename of the added file. The user can triggered the + skip of the add. This is adding a 'skipped' status in the file list result value. + - PCLZIP_CB_POST_ADD : will be called after each add of a file. + Nothing can be triggered from that point. + - Two status are added in the file list returned as function result : skipped & filename_too_long + 'skipped' is used when a call-back function ask for skipping the file. + 'filename_too_long' is used while adding a file with a too long filename to archive (the file is + not added) + - Adding the function PclZipUtilPathInclusion(), that check the inclusion of a path into + a directory. + - Add a check of the presence of the archive file before some actions (like list, ...) + - Add the initialisation of field "index" in header array. This means that by + default index will be -1 when not explicitly set by the methods. + + Version 1.2 : + - Adding a duplicate function. + - Adding a merge function. The merge function is a "quick merge" function, + it just append the content of an archive at the end of the first one. There + is no check for duplicate files or more recent files. + - Improve the search of the central directory end. + + Version 1.1.2 : + + - Changing the license of PclZip. PclZip is now released under the GNU / LGPL license + (see License section). + - Adding the optional support of a static temporary directory. You will need to configure + the constant PCLZIP_TEMPORARY_DIR if you want to use this feature. + - Improving the rename() function. In some cases rename() does not work (different + Filesystems), so it will be replaced by a copy() + unlink() functions. + + Version 1.1.1 : + + - Maintenance release, no new feature. + + Version 1.1 : + + - New method Add() : adding files in the archive + - New method ExtractByIndex() : partial extract of the archive, files are identified by + their index in the archive + - New method DeleteByIndex() : delete some files/folder entries from the archive, + files are identified by their index in the archive. + - Adding a test of the zlib extension presence. If not present abort the script. + + Version 1.0.1 : + + - No new feature + + +3 - Corrected bugs +================== + + Corrected in Version 2.0 : + - Corrected : During an extraction, if a call-back fucntion is used and try to skip + a file, all the extraction process is stopped. + + Corrected in Version 1.3 : + - Corrected : Support of static synopsis for method extract() is broken. + - Corrected : invalid size of archive content field (0xFF) should be (0xFFFF). + - Corrected : When an extract is done with a remove_path parameter, the entry for + the directory with exactly the same path is not skipped/filtered. + - Corrected : extractByIndex() and deleteByIndex() were not managing index in the + right way. For example indexes '1,3-5,11' will only extract files 1 and 11. This + is due to a sort of the index resulting table that puts 11 before 3-5 (sort on + string and not interger). The sort is temporarilly removed, this means that + you must provide a sorted list of index ranges. + + Corrected in Version 1.2 : + + - Nothing. + + Corrected in Version 1.1.2 : + + - Corrected : Winzip is unable to delete or add new files in a PclZip created archives. + + Corrected in Version 1.1.1 : + + - Corrected : When archived file is not compressed (0% compression), the + extract method fails. + + Corrected in Version 1.1 : + + - Corrected : Adding a complete tree of folder may result in a bad archive + creation. + + Corrected in Version 1.0.1 : + + - Corrected : Error while compressing files greater than PCLZIP_READ_BLOCK_SIZE (default=1024). + + +4 - Known bugs or limitations +============================= + + Please publish bugs reports in SourceForge : + http://sourceforge.net/tracker/?group_id=40254&atid=427564 + + In Version 2.x : + - PclZip does only support file uncompressed or compressed with deflate (compression method 8) + - PclZip does not support password protected zip archive + - Some concern were seen when changing mtime of a file while archiving. + Seems to be linked to Daylight Saving Time (PclTest_changing_mtime). + + In Version 1.2 : + + - merge() methods does not check for duplicate files or last date of modifications. + + In Version 1.1 : + + - Limitation : Using 'extract' fields in the file header in the zip archive is not supported. + - WinZip is unable to delete a single file in a PclZip created archive. It is also unable to + add a file in a PclZip created archive. (Corrected in v.1.2) + + In Version 1.0.1 : + + - Adding a complete tree of folder may result in a bad archive + creation. (Corrected in V.1.1). + - Path given to methods must be in the unix format (/) and not the Windows format (\). + Workaround : Use only / directory separators. + - PclZip is using temporary files that are sometime the name of the file with a .tmp or .gz + added suffix. Files with these names may already exist and may be overwritten. + Workaround : none. + - PclZip does not check if the zlib extension is present. If it is absent, the zip + file is not created and the lib abort without warning. + Workaround : enable the zlib extension on the php install + + In Version 1.0 : + + - Error while compressing files greater than PCLZIP_READ_BLOCK_SIZE (default=1024). + (Corrected in v.1.0.1) + - Limitation : Multi-disk zip archive are not supported. + + +5 - License +=========== + + Since version 1.1.2, PclZip Library is released under GNU/LGPL license. + This library is free, so you can use it at no cost. + + HOWEVER, if you release a script, an application, a library or any kind of + code using PclZip library (or a part of it), YOU MUST : + - Indicate in the documentation (or a readme file), that your work + uses PclZip Library, and make a reference to the author and the web site + http://www.phpconcept.net + - Gives the ability to the final user to update the PclZip libary. + + I will also appreciate that you send me a mail (vincent@phpconcept.net), just to + be aware that someone is using PclZip. + + For more information about GNU/LGPL license : http://www.gnu.org + +6 - Warning +================= + + This library and the associated files are non commercial, non professional work. + It should not have unexpected results.
