Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc., <http://fsf.org/>

Everyone is permitted to copy and distribute verbatim copies
|
| 7 |
+
of this license document, but changing it is not allowed.
|

+
Preamble
|
| 10 |
+
|
| 11 |
+
The licenses for most software are designed to take away your
|
| 12 |
+
freedom to share and change it. By contrast, the GNU General Public
|
| 13 |
+
License is intended to guarantee your freedom to share and change free
|
| 14 |
+
software--to make sure the software is free for all its users. This
|
| 15 |
+
General Public License applies to most of the Free Software
|
| 16 |
+
Foundation's software and to any other program whose authors commit to
|
| 17 |
+
using it. (Some other Free Software Foundation software is covered by
|
| 18 |
+
the GNU Lesser General Public License instead.) You can apply it to
|
| 19 |
+
your programs, too.
|
| 20 |
+
|
| 21 |
+
When we speak of free software, we are referring to freedom, not
|
| 22 |
+
price. Our General Public Licenses are designed to make sure that you
|
| 23 |
+
have the freedom to distribute copies of free software (and charge for
|
| 24 |
+
this service if you wish), that you receive source code or can get it
|
| 25 |
+
if you want it, that you can change the software or use pieces of it
|
| 26 |
+
in new free programs; and that you know you can do these things.
|
| 27 |
+
|
| 28 |
+
To protect your rights, we need to make restrictions that forbid
|
| 29 |
+
anyone to deny you these rights or to ask you to surrender the rights.
|
| 30 |
+
These restrictions translate to certain responsibilities for you if you
|
| 31 |
+
distribute copies of the software, or if you modify it.
|
| 32 |
+
|
| 33 |
+
For example, if you distribute copies of such a program, whether
|
| 34 |
+
gratis or for a fee, you must give the recipients all the rights that
|
| 35 |
+
you have. You must make sure that they, too, receive or can get the
|
| 36 |
+
source code. And you must show them these terms so they know their
|
| 37 |
+
rights.
|
| 38 |
+
|
| 39 |
+
We protect your rights with two steps: (1) copyright the software, and
|
| 40 |
+
(2) offer you this license which gives you legal permission to copy,
|
| 41 |
+
distribute and/or modify the software.
|
| 42 |
+
|
| 43 |
+
Also, for each author's protection and ours, we want to make certain
|
| 44 |
+
that everyone understands that there is no warranty for this free
|
| 45 |
+
software. If the software is modified by someone else and passed on, we
|
| 46 |
+
want its recipients to know that what they have is not the original, so
|
| 47 |
+
that any problems introduced by others will not reflect on the original
|
| 48 |
+
authors' reputations.
|
| 49 |
+
|
| 50 |
+
Finally, any free program is threatened constantly by software
|
| 51 |
+
patents. We wish to avoid the danger that redistributors of a free
|
| 52 |
+
program will individually obtain patent licenses, in effect making the
|
| 53 |
+
program proprietary. To prevent this, we have made it clear that any
|
| 54 |
+
patent must be licensed for everyone's free use or not licensed at all.
|
| 55 |
+
|
| 56 |
+
The precise terms and conditions for copying, distribution and
|
| 57 |
+
modification follow.
|
| 58 |
+
|
| 59 |
+
GNU GENERAL PUBLIC LICENSE
|
| 60 |
+
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
| 61 |
+
|
| 62 |
+
0. This License applies to any program or other work which contains
|
| 63 |
+
a notice placed by the copyright holder saying it may be distributed
|
| 64 |
+
under the terms of this General Public License. The "Program", below,
|
| 65 |
+
refers to any such program or work, and a "work based on the Program"
|
| 66 |
+
means either the Program or any derivative work under copyright law:
|
| 67 |
+
that is to say, a work containing the Program or a portion of it,
|
| 68 |
+
either verbatim or with modifications and/or translated into another
|
| 69 |
+
language. (Hereinafter, translation is included without limitation in
|
| 70 |
+
the term "modification".) Each licensee is addressed as "you".
|
| 71 |
+
|
| 72 |
+
Activities other than copying, distribution and modification are not
|
| 73 |
+
covered by this License; they are outside its scope. The act of
|
| 74 |
+
running the Program is not restricted, and the output from the Program
|
| 75 |
+
is covered only if its contents constitute a work based on the
|
| 76 |
+
Program (independent of having been made by running the Program).
|
| 77 |
+
Whether that is true depends on what the Program does.
|
| 78 |
+
|
| 79 |
+
1. You may copy and distribute verbatim copies of the Program's
|
| 80 |
+
source code as you receive it, in any medium, provided that you
|
| 81 |
+
conspicuously and appropriately publish on each copy an appropriate
|
| 82 |
+
copyright notice and disclaimer of warranty; keep intact all the
|
| 83 |
+
notices that refer to this License and to the absence of any warranty;
|
| 84 |
+
and give any other recipients of the Program a copy of this License
|
| 85 |
+
along with the Program.
|
| 86 |
+
|
| 87 |
+
You may charge a fee for the physical act of transferring a copy, and
|
| 88 |
+
you may at your option offer warranty protection in exchange for a fee.
|
| 89 |
+
|
| 90 |
+
2. You may modify your copy or copies of the Program or any portion
|
| 91 |
+
of it, thus forming a work based on the Program, and copy and
|
| 92 |
+
distribute such modifications or work under the terms of Section 1
|
| 93 |
+
above, provided that you also meet all of these conditions:
|
| 94 |
+
|
| 95 |
+
a) You must cause the modified files to carry prominent notices
|
| 96 |
+
stating that you changed the files and the date of any change.
|
| 97 |
+
|
| 98 |
+
b) You must cause any work that you distribute or publish, that in
|
| 99 |
+
whole or in part contains or is derived from the Program or any
|
| 100 |
+
part thereof, to be licensed as a whole at no charge to all third
|
| 101 |
+
parties under the terms of this License.
|
| 102 |
+
|
| 103 |
+
c) If the modified program normally reads commands interactively
|
| 104 |
+
when run, you must cause it, when started running for such
|
| 105 |
+
interactive use in the most ordinary way, to print or display an
|
| 106 |
+
announcement including an appropriate copyright notice and a
|
| 107 |
+
notice that there is no warranty (or else, saying that you provide
|
| 108 |
+
a warranty) and that users may redistribute the program under
|
| 109 |
+
these conditions, and telling the user how to view a copy of this
|
| 110 |
+
License. (Exception: if the Program itself is interactive but
|
| 111 |
+
does not normally print such an announcement, your work based on
|
| 112 |
+
the Program is not required to print an announcement.)
|
| 113 |
+
|
| 114 |
+
These requirements apply to the modified work as a whole. If
|
| 115 |
+
identifiable sections of that work are not derived from the Program,
|
| 116 |
+
and can be reasonably considered independent and separate works in
|
| 117 |
+
themselves, then this License, and its terms, do not apply to those
|
| 118 |
+
sections when you distribute them as separate works. But when you
|
| 119 |
+
distribute the same sections as part of a whole which is a work based
|
| 120 |
+
on the Program, the distribution of the whole must be on the terms of
|
| 121 |
+
this License, whose permissions for other licensees extend to the
|
| 122 |
+
entire whole, and thus to each and every part regardless of who wrote it.
|
| 123 |
+
|
| 124 |
+
Thus, it is not the intent of this section to claim rights or contest
|
| 125 |
+
your rights to work written entirely by you; rather, the intent is to
|
| 126 |
+
exercise the right to control the distribution of derivative or
|
| 127 |
+
collective works based on the Program.
|
| 128 |
+
|
| 129 |
+
In addition, mere aggregation of another work not based on the Program
|
| 130 |
+
with the Program (or with a work based on the Program) on a volume of
|
| 131 |
+
a storage or distribution medium does not bring the other work under
|
| 132 |
+
the scope of this License.
|
| 133 |
+
|
| 134 |
+
3. You may copy and distribute the Program (or a work based on it,
|
| 135 |
+
under Section 2) in object code or executable form under the terms of
|
| 136 |
+
Sections 1 and 2 above provided that you also do one of the following:
|
| 137 |
+
|
| 138 |
+
a) Accompany it with the complete corresponding machine-readable
|
| 139 |
+
source code, which must be distributed under the terms of Sections
|
| 140 |
+
1 and 2 above on a medium customarily used for software interchange; or,
|
| 141 |
+
|
| 142 |
+
b) Accompany it with a written offer, valid for at least three
|
| 143 |
+
years, to give any third party, for a charge no more than your
|
| 144 |
+
cost of physically performing source distribution, a complete
|
| 145 |
+
machine-readable copy of the corresponding source code, to be
|
| 146 |
+
distributed under the terms of Sections 1 and 2 above on a medium
|
| 147 |
+
customarily used for software interchange; or,
|
| 148 |
+
|
| 149 |
+
c) Accompany it with the information you received as to the offer
|
| 150 |
+
to distribute corresponding source code. (This alternative is
|
| 151 |
+
allowed only for noncommercial distribution and only if you
|
| 152 |
+
received the program in object code or executable form with such
|
| 153 |
+
an offer, in accord with Subsection b above.)
|
| 154 |
+
|
| 155 |
+
The source code for a work means the preferred form of the work for
|
| 156 |
+
making modifications to it. For an executable work, complete source
|
| 157 |
+
code means all the source code for all modules it contains, plus any
|
| 158 |
+
associated interface definition files, plus the scripts used to
|
| 159 |
+
control compilation and installation of the executable. However, as a
|
| 160 |
+
special exception, the source code distributed need not include
|
| 161 |
+
anything that is normally distributed (in either source or binary
|
| 162 |
+
form) with the major components (compiler, kernel, and so on) of the
|
| 163 |
+
operating system on which the executable runs, unless that component
|
| 164 |
+
itself accompanies the executable.
|
| 165 |
+
|
| 166 |
+
If distribution of executable or object code is made by offering
|
| 167 |
+
access to copy from a designated place, then offering equivalent
|
| 168 |
+
access to copy the source code from the same place counts as
|
| 169 |
+
distribution of the source code, even though third parties are not
|
| 170 |
+
compelled to copy the source along with the object code.
|
| 171 |
+
|
| 172 |
+
4. You may not copy, modify, sublicense, or distribute the Program
|
| 173 |
+
except as expressly provided under this License. Any attempt
|
| 174 |
+
otherwise to copy, modify, sublicense or distribute the Program is
|
| 175 |
+
void, and will automatically terminate your rights under this License.
|
| 176 |
+
However, parties who have received copies, or rights, from you under
|
| 177 |
+
this License will not have their licenses terminated so long as such
|
| 178 |
+
parties remain in full compliance.
|
| 179 |
+
|
| 180 |
+
5. You are not required to accept this License, since you have not
|
| 181 |
+
signed it. However, nothing else grants you permission to modify or
|
| 182 |
+
distribute the Program or its derivative works. These actions are
|
| 183 |
+
prohibited by law if you do not accept this License. Therefore, by
|
| 184 |
+
modifying or distributing the Program (or any work based on the
|
| 185 |
+
Program), you indicate your acceptance of this License to do so, and
|
| 186 |
+
all its terms and conditions for copying, distributing or modifying
|
| 187 |
+
the Program or works based on it.
|
| 188 |
+
|
| 189 |
+
6. Each time you redistribute the Program (or any work based on the
|
| 190 |
+
Program), the recipient automatically receives a license from the
|
| 191 |
+
original licensor to copy, distribute or modify the Program subject to
|
| 192 |
+
these terms and conditions. You may not impose any further
|
| 193 |
+
restrictions on the recipients' exercise of the rights granted herein.
|
| 194 |
+
You are not responsible for enforcing compliance by third parties to
|
| 195 |
+
this License.
|
| 196 |
+
|
| 197 |
+
7. If, as a consequence of a court judgment or allegation of patent
|
| 198 |
+
infringement or for any other reason (not limited to patent issues),
|
| 199 |
+
conditions are imposed on you (whether by court order, agreement or
|
| 200 |
+
otherwise) that contradict the conditions of this License, they do not
|
| 201 |
+
excuse you from the conditions of this License. If you cannot
|
| 202 |
+
distribute so as to satisfy simultaneously your obligations under this
|
| 203 |
+
License and any other pertinent obligations, then as a consequence you
|
| 204 |
+
may not distribute the Program at all. For example, if a patent
|
| 205 |
+
license would not permit royalty-free redistribution of the Program by
|
| 206 |
+
all those who receive copies directly or indirectly through you, then
|
| 207 |
+
the only way you could satisfy both it and this License would be to
|
| 208 |
+
refrain entirely from distribution of the Program.
|
| 209 |
+
|
| 210 |
+
If any portion of this section is held invalid or unenforceable under
|
| 211 |
+
any particular circumstance, the balance of the section is intended to
|
| 212 |
+
apply and the section as a whole is intended to apply in other
|
| 213 |
+
circumstances.
|
| 214 |
+
|
| 215 |
+
It is not the purpose of this section to induce you to infringe any
|
| 216 |
+
patents or other property right claims or to contest validity of any
|
| 217 |
+
such claims; this section has the sole purpose of protecting the
|
| 218 |
+
integrity of the free software distribution system, which is
|
| 219 |
+
implemented by public license practices. Many people have made
|
| 220 |
+
generous contributions to the wide range of software distributed
|
| 221 |
+
through that system in reliance on consistent application of that
|
| 222 |
+
system; it is up to the author/donor to decide if he or she is willing
|
| 223 |
+
to distribute software through any other system and a licensee cannot
|
| 224 |
+
impose that choice.
|
| 225 |
+
|
| 226 |
+
This section is intended to make thoroughly clear what is believed to
|
| 227 |
+
be a consequence of the rest of this License.
|
| 228 |
+
|
| 229 |
+
8. If the distribution and/or use of the Program is restricted in
|
| 230 |
+
certain countries either by patents or by copyrighted interfaces, the
|
| 231 |
+
original copyright holder who places the Program under this License
|
| 232 |
+
may add an explicit geographical distribution limitation excluding
|
| 233 |
+
those countries, so that distribution is permitted only in or among
|
| 234 |
+
countries not thus excluded. In such case, this License incorporates
|
| 235 |
+
the limitation as if written in the body of this License.
|
| 236 |
+
|
| 237 |
+
9. The Free Software Foundation may publish revised and/or new versions
|
| 238 |
+
of the General Public License from time to time. Such new versions will
|
| 239 |
+
be similar in spirit to the present version, but may differ in detail to
|
| 240 |
+
address new problems or concerns.
|
| 241 |
+
|
| 242 |
+
Each version is given a distinguishing version number. If the Program
|
| 243 |
+
specifies a version number of this License which applies to it and "any
|
| 244 |
+
later version", you have the option of following the terms and conditions
|
| 245 |
+
either of that version or of any later version published by the Free
|
| 246 |
+
Software Foundation. If the Program does not specify a version number of
|
| 247 |
+
this License, you may choose any version ever published by the Free Software
|
| 248 |
+
Foundation.
|
| 249 |
+
|
| 250 |
+
10. If you wish to incorporate parts of the Program into other free
|
| 251 |
+
programs whose distribution conditions are different, write to the author
|
| 252 |
+
to ask for permission. For software which is copyrighted by the Free
|
| 253 |
+
Software Foundation, write to the Free Software Foundation; we sometimes
|
| 254 |
+
make exceptions for this. Our decision will be guided by the two goals
|
| 255 |
+
of preserving the free status of all derivatives of our free software and
|
| 256 |
+
of promoting the sharing and reuse of software generally.
|
| 257 |
+
|
| 258 |
+
NO WARRANTY
|
| 259 |
+
|
| 260 |
+
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
| 261 |
+
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
| 262 |
+
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
| 263 |
+
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
| 264 |
+
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
| 265 |
+
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
| 266 |
+
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
| 267 |
+
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
| 268 |
+
REPAIR OR CORRECTION.
|
| 269 |
+
|
| 270 |
+
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
| 271 |
+
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
| 272 |
+
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
| 273 |
+
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
| 274 |
+
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
| 275 |
+
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
| 276 |
+
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
| 277 |
+
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
| 278 |
+
POSSIBILITY OF SUCH DAMAGES.
|
| 279 |
+
|
| 280 |
+
END OF TERMS AND CONDITIONS
|
| 281 |
+
|
| 282 |
+
How to Apply These Terms to Your New Programs
|
| 283 |
+
|
| 284 |
+
If you develop a new program, and you want it to be of the greatest
|
| 285 |
+
possible use to the public, the best way to achieve this is to make it
|
| 286 |
+
free software which everyone can redistribute and change under these terms.
|
| 287 |
+
|
| 288 |
+
To do so, attach the following notices to the program. It is safest
|
| 289 |
+
to attach them to the start of each source file to most effectively
|
| 290 |
+
convey the exclusion of warranty; and each file should have at least
|
| 291 |
+
the "copyright" line and a pointer to where the full notice is found.
|
| 292 |
+
|
| 293 |
+

with this program; if not, write to the Free Software Foundation, Inc.,

+
|
| 310 |
+
Also add information on how to contact you by electronic and paper mail.
|
| 311 |
+
|
| 312 |
+
If the program is interactive, make it output a short notice like this
|
| 313 |
+
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
|
| 318 |

under certain conditions; type `show c' for details.
|
| 319 |
+
|
| 320 |
+
The hypothetical commands `show w' and `show c' should show the appropriate
|
| 321 |
+
parts of the General Public License. Of course, the commands you use may
|
| 322 |
+
be called something other than `show w' and `show c'; they could even be
|
| 323 |
+
mouse-clicks or menu items--whatever suits your program.
|
| 324 |
+
|
| 325 |
+
You should also get your employer (if you work as a programmer) or your
|
| 326 |
+
school, if any, to sign a "copyright disclaimer" for the program, if
|
| 327 |
+
necessary. Here is a sample; alter the names:

This General Public License does not permit incorporating your program into
|
| 336 |
+
proprietary programs. If your program is a subroutine library, you may
|
| 337 |
+
consider it more useful to permit linking proprietary applications with the
|
| 338 |
+
library. If this is what you want to do, use the GNU Lesser General
|
| 339 |
+
Public License instead of this License.

Optimize pages for faster load and render in the browser.
|
| 12 |
+
|
| 13 |
+
== Description ==
|
| 14 |
+
|
| 15 |
+
This plugin supports a few features that may improve the performance of page loading and rendering in the browser:
|
| 16 |
+
|
| 17 |
+
* Concatenate CSS
|
| 18 |
+
* Concatenate JavaScript
|
| 19 |
+
* Execution timing of non-critical scripts
|
| 20 |
+
|
| 21 |
+
Notes:
|
| 22 |
+
* Changing script execution timing can be risky and will not work well for all sites.
|
| 23 |
+
|
| 24 |
+
== Installation ==
|
| 25 |
+
|
| 26 |
+
This plugin uses sensible defaults so it can operate without configuration, but there are a number of constants you may use for a custom configuration.
|
| 27 |
+
|
| 28 |
+
= PAGE_OPTIMIZE_CACHE_DIR =
|
| 29 |
+
|
| 30 |
+
Page Optimize caches concatenated scripts and styles by default, and this constant controls where the cache files are stored. The default directory is `cache/page_optimize` under your site's `wp-content` folder.
|
| 31 |
+
|
| 32 |
+
To change the cache location, set this constant to the absolute filesystem path of that location.
|
| 33 |
+
|
| 34 |
+
To disable caching, set this constant to `false`. Please note that disabling Page Optimize caching may negatively impact performance unless you are caching elsewhere.
|
| 35 |
+
|
| 36 |
+
== Testing ==
|
| 37 |
+
|
| 38 |
+
To test features without enabling them for the entire site, you may append query params to a WordPress post or page URL. For example, to test enabling JavaScript concatenation for `https://example.com/blog/`, you can use the URL `https://example.com/blog/?concat-js=1`.
|
| 39 |
+
|
| 40 |
+
Supported query params:
|
| 41 |
+
|
| 42 |
+
* `concat-css` controls CSS concatenation. Values: `1` for ON and `0` for OFF.
|
| 43 |
+
* `concat-js` controls JavaScript concatenation. Values: `1` for ON and `0` for OFF.
|
| 44 |
+
* `load-mode-js` controls how non-critical JavaScript are loaded. Values: 'defer' for [deferred](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#attr-defer), 'async' for [async loading](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#attr-async), any other value indicates the feature should be disabled.
|

|

+
Initial release. No changes yet. :)
