Remove NSInputStream used in HTTPTransportMac and use a CFReadStream instead.

Browse Source 
NSInputStream requires overriding and implementing private methods in order to
use it with NSURLConnection [1]. It is cleaner to use the private but stable
and open source CFStreamAbstract.h header from CF-Lite to implement a
CFReadStream. Since CFReadStream is toll-free bridged to NSInputStream, the
remainder of the HTTPTransport code can remain unchanged.

APPLE PUBLIC SOURCE LICENSE
Version 2.0 - August 6, 2003
Please read this License carefully before downloading this software. By
downloading or using this software, you are agreeing to be bound by the terms
of this License. If you do not or cannot agree to the terms of this License,
please do not download or use the software.
Apple Note: In January 2007, Apple changed its corporate name from "Apple
Computer, Inc." to "Apple Inc." This change has been reflected below and
copyright years updated, but no other changes have been made to the APSL 2.0.
1. General; Definitions. This License applies to any program or other
work which Apple Inc. ("Apple") makes publicly available and which contains a
notice placed by Apple identifying such program or work as "Original Code" and
stating that it is subject to the terms of this Apple Public Source License
version 2.0 ("License"). As used in this License:
1.1 "Applicable Patent Rights" mean: (a) in the case where Apple is the
grantor of rights, (i) claims of patents that are now or hereafter acquired,
owned by or assigned to Apple and (ii) that cover subject matter contained in
the Original Code, but only to the extent necessary to use, reproduce and/or
distribute the Original Code without infringement; and (b) in the case where
You are the grantor of rights, (i) claims of patents that are now or hereafter
acquired, owned by or assigned to You and (ii) that cover subject matter in
Your Modifications, taken alone or in combination with Original Code.
1.2 "Contributor" means any person or entity that creates or contributes to
the creation of Modifications.
1.3 "Covered Code" means the Original Code, Modifications, the combination
of Original Code and any Modifications, and/or any respective portions thereof.
1.4 "Externally Deploy" means: (a) to sublicense, distribute or otherwise
make Covered Code available, directly or indirectly, to anyone other than You;
and/or (b) to use Covered Code, alone or as part of a Larger Work, in any way
to provide a service, including but not limited to delivery of content, through
electronic communication with a client other than You.
1.5 "Larger Work" means a work which combines Covered Code or portions
thereof with code not governed by the terms of this License.
1.6 "Modifications" mean any addition to, deletion from, and/or change to,
the substance and/or structure of the Original Code, any previous
Modifications, the combination of Original Code and any previous Modifications,
and/or any respective portions thereof. When code is released as a series of
files, a Modification is: (a) any addition to or deletion from the contents of
a file containing Covered Code; and/or (b) any new file or other representation
of computer program statements that contains any part of Covered Code.
1.7 "Original Code" means (a) the Source Code of a program or other work as
originally made available by Apple under this License, including the Source
Code of any updates or upgrades to such programs or works made available by
Apple under this License, and that has been expressly identified by Apple as
such in the header file(s) of such work; and (b) the object code compiled from
such Source Code and originally made available by Apple under this License
1.8 "Source Code" means the human readable form of a program or other work
that is suitable for making modifications to it, including all modules it
contains, plus any associated interface definition files, scripts used to
control compilation and installation of an executable (object code).
1.9 "You" or "Your" means an individual or a legal entity exercising rights
under this License. For legal entities, "You" or "Your" includes any entity
which controls, is controlled by, or is under common control with, You, where
"control" means (a) the power, direct or indirect, to cause the direction or
management of such entity, whether by contract or otherwise, or (b) ownership
of fifty percent (50%) or more of the outstanding shares or beneficial
ownership of such entity.
2. Permitted Uses; Conditions & Restrictions. Subject to the terms and
conditions of this License, Apple hereby grants You, effective on the date You
accept this License and download the Original Code, a world-wide, royalty-free,
non-exclusive license, to the extent of Apple's Applicable Patent Rights and
copyrights covering the Original Code, to do the following:
2.1 Unmodified Code. You may use, reproduce, display, perform, internally
distribute within Your organization, and Externally Deploy verbatim, unmodified
copies of the Original Code, for commercial or non-commercial purposes,
provided that in each instance:
(a) You must retain and reproduce in all copies of Original Code the
copyright and other proprietary notices and disclaimers of Apple as they appear
in the Original Code, and keep intact all notices in the Original Code that
refer to this License; and
(b) You must include a copy of this License with every copy of Source Code
of Covered Code and documentation You distribute or Externally Deploy, and You
may not offer or impose any terms on such Source Code that alter or restrict
this License or the recipients' rights hereunder, except as permitted under
Section 6.
2.2 Modified Code. You may modify Covered Code and use, reproduce,
display, perform, internally distribute within Your organization, and
Externally Deploy Your Modifications and Covered Code, for commercial or
non-commercial purposes, provided that in each instance You also meet all of
these conditions:
(a) You must satisfy all the conditions of Section 2.1 with respect to the
Source Code of the Covered Code;
(b) You must duplicate, to the extent it does not already exist, the notice
in Exhibit A in each file of the Source Code of all Your Modifications, and
cause the modified files to carry prominent notices stating that You changed
the files and the date of any change; and
(c) If You Externally Deploy Your Modifications, You must make Source Code
of all Your Externally Deployed Modifications either available to those to whom
You have Externally Deployed Your Modifications, or publicly available. Source
Code of Your Externally Deployed Modifications must be released under the terms
set forth in this License, including the license grants set forth in Section 3
below, for as long as you Externally Deploy the Covered Code or twelve (12)
months from the date of initial External Deployment, whichever is longer. You
should preferably distribute the Source Code of Your Externally Deployed
Modifications electronically (e.g. download from a web site).
2.3 Distribution of Executable Versions. In addition, if You Externally
Deploy Covered Code (Original Code and/or Modifications) in object code,
executable form only, You must include a prominent notice, in the code itself
as well as in related documentation, stating that Source Code of the Covered
Code is available under the terms of this License with information on how and
where to obtain such Source Code.
2.4 Third Party Rights. You expressly acknowledge and agree that although
Apple and each Contributor grants the licenses to their respective portions of
the Covered Code set forth herein, no assurances are provided by Apple or any
Contributor that the Covered Code does not infringe the patent or other
intellectual property rights of any other entity. Apple and each Contributor
disclaim any liability to You for claims brought by any other entity based on
infringement of intellectual property rights or otherwise. As a condition to
exercising the rights and licenses granted hereunder, You hereby assume sole
responsibility to secure any other intellectual property rights needed, if any.
For example, if a third party patent license is required to allow You to
distribute the Covered Code, it is Your responsibility to acquire that license
before distributing the Covered Code.
3. Your Grants. In consideration of, and as a condition to, the licenses
granted to You under this License, You hereby grant to any person or entity
receiving or distributing Covered Code under this License a non-exclusive,
royalty-free, perpetual, irrevocable license, under Your Applicable Patent
Rights and other intellectual property rights (other than patent) owned or
controlled by You, to use, reproduce, display, perform, modify, sublicense,
distribute and Externally Deploy Your Modifications of the same scope and
extent as Apple's licenses under Sections 2.1 and 2.2 above.
4. Larger Works. You may create a Larger Work by combining Covered Code
with other code not governed by the terms of this License and distribute the
Larger Work as a single product. In each such instance, You must make sure the
requirements of this License are fulfilled for the Covered Code or any portion
thereof.
5. Limitations on Patent License. Except as expressly stated in Section
2, no other patent rights, express or implied, are granted by Apple herein.
Modifications and/or Larger Works may require additional patent licenses from
Apple which Apple may grant in its sole discretion.
6. Additional Terms. You may choose to offer, and to charge a fee for,
warranty, support, indemnity or liability obligations and/or other rights
consistent with the scope of the license granted herein ("Additional Terms") to
one or more recipients of Covered Code. However, You may do so only on Your own
behalf and as Your sole responsibility, and not on behalf of Apple or any
Contributor. You must obtain the recipient's agreement that any such Additional
Terms are offered by You alone, and You hereby agree to indemnify, defend and
hold Apple and every Contributor harmless for any liability incurred by or
claims asserted against Apple or such Contributor by reason of any such
Additional Terms.
7. Versions of the License. Apple may publish revised and/or new versions
of this License from time to time. Each version will be given a distinguishing
version number. Once Original Code has been published under a particular
version of this License, You may continue to use it under the terms of that
version. You may also choose to use such Original Code under the terms of any
subsequent version of this License published by Apple. No one other than Apple
has the right to modify the terms applicable to Covered Code created under this
License.
8. NO WARRANTY OR SUPPORT. The Covered Code may contain in whole or in
part pre-release, untested, or not fully tested works. The Covered Code may
contain errors that could cause failures or loss of data, and may be incomplete
or contain inaccuracies. You expressly acknowledge and agree that use of the
Covered Code, or any portion thereof, is at Your sole and entire risk. THE
COVERED CODE IS PROVIDED "AS IS" AND WITHOUT WARRANTY, UPGRADES OR SUPPORT OF
ANY KIND AND APPLE AND APPLE'S LICENSOR(S) (COLLECTIVELY REFERRED TO AS "APPLE"
FOR THE PURPOSES OF SECTIONS 8 AND 9) AND ALL CONTRIBUTORS EXPRESSLY DISCLAIM
ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT
LIMITED TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF MERCHANTABILITY, OF
SATISFACTORY QUALITY, OF FITNESS FOR A PARTICULAR PURPOSE, OF ACCURACY, OF
QUIET ENJOYMENT, AND NONINFRINGEMENT OF THIRD PARTY RIGHTS. APPLE AND EACH
CONTRIBUTOR DOES NOT WARRANT AGAINST INTERFERENCE WITH YOUR ENJOYMENT OF THE
COVERED CODE, THAT THE FUNCTIONS CONTAINED IN THE COVERED CODE WILL MEET YOUR
REQUIREMENTS, THAT THE OPERATION OF THE COVERED CODE WILL BE UNINTERRUPTED OR
ERROR-FREE, OR THAT DEFECTS IN THE COVERED CODE WILL BE CORRECTED. NO ORAL OR
WRITTEN INFORMATION OR ADVICE GIVEN BY APPLE, AN APPLE AUTHORIZED
REPRESENTATIVE OR ANY CONTRIBUTOR SHALL CREATE A WARRANTY. You acknowledge
that the Covered Code is not intended for use in the operation of nuclear
facilities, aircraft navigation, communication systems, or air traffic control
machines in which case the failure of the Covered Code could lead to death,
personal injury, or severe physical or environmental damage.
9. LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO
EVENT SHALL APPLE OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL, SPECIAL,
INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE OR
YOUR USE OR INABILITY TO USE THE COVERED CODE, OR ANY PORTION THEREOF, WHETHER
UNDER A THEORY OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE), PRODUCTS
LIABILITY OR OTHERWISE, EVEN IF APPLE OR SUCH CONTRIBUTOR HAS BEEN ADVISED OF
THE POSSIBILITY OF SUCH DAMAGES AND NOTWITHSTANDING THE FAILURE OF ESSENTIAL
PURPOSE OF ANY REMEDY. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF
LIABILITY OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT
APPLY TO YOU. In no event shall Apple's total liability to You for all damages
(other than as may be required by applicable law) under this License exceed the
amount of fifty dollars ($50.00).
10. Trademarks. This License does not grant any rights to use the
trademarks or trade names "Apple", "Mac", "Mac OS", "QuickTime", "QuickTime
Streaming Server" or any other trademarks, service marks, logos or trade names
belonging to Apple (collectively "Apple Marks") or to any trademark, service
mark, logo or trade name belonging to any Contributor. You agree not to use
any Apple Marks in or as part of the name of products derived from the Original
Code or to endorse or promote products derived from the Original Code other
than as expressly permitted by and in strict compliance at all times with
Apple's third party trademark usage guidelines which are posted at
http://www.apple.com/legal/guidelinesfor3rdparties.html.
11. Ownership. Subject to the licenses granted under this License, each
Contributor retains all rights, title and interest in and to any Modifications
made by such Contributor. Apple retains all rights, title and interest in and
to the Original Code and any Modifications made by or on behalf of Apple
("Apple Modifications"), and such Apple Modifications will not be automatically
subject to this License. Apple may, at its sole discretion, choose to license
such Apple Modifications under this License, or on different terms from those
contained in this License or may choose not to license them at all.
12. Termination.
12.1 Termination. This License and the rights granted hereunder will
terminate:
(a) automatically without notice from Apple if You fail to comply with any
term(s) of this License and fail to cure such breach within 30 days of becoming
aware of such breach;
(b) immediately in the event of the circumstances described in Section
13.5(b); or
(c) automatically without notice from Apple if You, at any time during the
term of this License, commence an action for patent infringement against Apple;
provided that Apple did not first commence an action for patent infringement
against You in that instance.
12.2 Effect of Termination. Upon termination, You agree to immediately stop
any further use, reproduction, modification, sublicensing and distribution of
the Covered Code. All sublicenses to the Covered Code which have been properly
granted prior to termination shall survive any termination of this License.
Provisions which, by their nature, should remain in effect beyond the
termination of this License shall survive, including but not limited to
Sections 3, 5, 8, 9, 10, 11, 12.2 and 13. No party will be liable to any other
for compensation, indemnity or damages of any sort solely as a result of
terminating this License in accordance with its terms, and termination of this
License will be without prejudice to any other right or remedy of any party.
13. Miscellaneous.
13.1 Government End Users. The Covered Code is a "commercial item" as
defined in FAR 2.101. Government software and technical data rights in the
Covered Code include only those rights customarily provided to the public as
defined in this License. This customary commercial license in technical data
and software is provided in accordance with FAR 12.211 (Technical Data) and
12.212 (Computer Software) and, for Department of Defense purchases, DFAR
252.227-7015 (Technical Data -- Commercial Items) and 227.7202-3 (Rights in
Commercial Computer Software or Computer Software Documentation). Accordingly,
all U.S. Government End Users acquire Covered Code with only those rights set
forth herein.
13.2 Relationship of Parties. This License will not be construed as
creating an agency, partnership, joint venture or any other form of legal
association between or among You, Apple or any Contributor, and You will not
represent to the contrary, whether expressly, by implication, appearance or
otherwise.
13.3 Independent Development. Nothing in this License will impair Apple's
right to acquire, license, develop, have others develop for it, market and/or
distribute technology or products that perform the same or similar functions
as, or otherwise compete with, Modifications, Larger Works, technology or
products that You may develop, produce, market or distribute.
13.4 Waiver; Construction. Failure by Apple or any Contributor to enforce
any provision of this License will not be deemed a waiver of future enforcement
of that or any other provision. Any law or regulation which provides that the
language of a contract shall be construed against the drafter will not apply to
this License.
13.5 Severability. (a) If for any reason a court of competent jurisdiction
finds any provision of this License, or portion thereof, to be unenforceable,
that provision of the License will be enforced to the maximum extent
permissible so as to effect the economic benefits and intent of the parties,
and the remainder of this License will continue in full force and effect. (b)
Notwithstanding the foregoing, if applicable law prohibits or restricts You
from fully and/or specifically complying with Sections 2 and/or 3 or prevents
the enforceability of either of those Sections, this License will immediately
terminate and You must immediately discontinue any use of the Covered Code and
destroy all copies of it that are in your possession or control.
13.6 Dispute Resolution. Any litigation or other dispute resolution between
You and Apple relating to this License shall take place in the Northern
District of California, and You and Apple hereby consent to the personal
jurisdiction of, and venue in, the state and federal courts within that
District with respect to this License. The application of the United Nations
Convention on Contracts for the International Sale of Goods is expressly
excluded.
13.7 Entire Agreement; Governing Law. This License constitutes the entire
agreement between the parties with respect to the subject matter hereof. This
License shall be governed by the laws of the United States and the State of
California, except that body of California law concerning conflicts of law.
Where You are located in the province of Quebec, Canada, the following clause
applies: The parties hereby confirm that they have requested that this License
and all related documents be drafted in English. Les parties ont exigé que le
présent contrat et tous les documents connexes soient rédigés en anglais.

CF_EXTERN_C_BEGIN
/* During a stream's lifetime, the open callback will be called once, followed by any number of openCompleted calls (until openCompleted returns TRUE). Then any number of read/canRead or write/canWrite calls, then a single close call. copyProperty can be called at any time. prepareAsynch will be called exactly once when the stream's client is first configured.
Expected semantics:
- open reserves any system resources that are needed. The stream may start the process of opening, returning TRUE immediately and setting openComplete to FALSE. When the open completes, _CFStreamSignalEvent should be called passing kCFStreamOpenCompletedEvent. openComplete should be set to TRUE only if the open operation completed in its entirety.
- openCompleted will only be called after open has been called, but before any kCFStreamOpenCompletedEvent has been received. Return TRUE, setting error.code to 0, if the open operation has completed. Return TRUE, setting error to the correct error code and domain if the open operation completed, but failed. Return FALSE if the open operation is still in-progress. If your open ever fails to complete (i.e. sets openComplete to FALSE), you must be implement the openCompleted callback.
- read should read into the given buffer, returning the number of bytes successfully read. read must block until at least one byte is available, but should not block until the entire buffer is filled; zero should only be returned if end-of-stream is encountered. atEOF should be set to true if the EOF is encountered, false otherwise. error.code should be set to zero if no error occurs; otherwise, error should be set to the appropriate values.
- getBuffer is an optimization to return an internal buffer of bytes read from the stream, and may return NULL. getBuffer itself may be NULL if the concrete implementation does not wish to provide an internal buffer. If implemented, it should set numBytesRead to the number of bytes available in the internal buffer (but should not exceed maxBytesToRead) and return a pointer to the base of the bytes.
- canRead will only be called once openCompleted reports that the stream has been successfully opened (or the initial open call succeeded). It should return whether there are bytes that can be read without blocking.
- write should write the bytes in the given buffer to the device, returning the number of bytes successfully written. write must block until at least one byte is written. error.code should be set to zero if no error occurs; otherwise, error should be set to the appropriate values.
- close should close the device, releasing any reserved system resources. close cannot fail (it may be called to abort the stream), and may be called at any time after open has been called. It will only be called once.
- copyProperty should return the value for the given property, or NULL if none exists. Composite streams (streams built on top of other streams) should take care to call CFStreamCopyProperty on the base stream if they do not recognize the property given, to give the underlying stream a chance to respond.
In all cases, errors returned by reference will be initialized to NULL by the caller, and if they are set to non-NULL, will
be released by the caller
