* see the CHANGES file |
|

|
|

Major changes in release 1.1.1: |
|
||||
* ares should now compile as C++ code (no longer uses reserved word |
|

"class"). |
|

|
|

Major changes in release 1.1.0: |
|

* Added ares_free_string() function so that memory can be freed in the |
|
||||
same layer as it is allocated, a desirable feature in some |
|
||||
environments. |
|
||||
* A few of the ares_dns.h macros are fixed to use the proper bitwise |
|
||||
operator. |
|

* Fixed a couple of fenceposts fixed in ares_expand_name()'s |
|
||||
bounds-checking. |
|
||||
* In process_timeouts(), extract query->next before calling |
|
||||
next_server() and possibly freeing the query structure. |
|
||||
* Casted arguments to ctype macros casted to unsigned char, since not |
|
||||
all char values are valid inputs to those macros according to ANSI. |

c-ares |
|
||||
====== |
|
||||
|
|
||||
This is c-ares, an asynchronous resolver library. It is intended for |
|
||||
applications which need to perform DNS queries without blocking, or need to |
|
||||
perform multiple DNS queries in parallel. The primary examples of such |
|
||||
applications are servers which communicate with multiple clients and programs |
|
||||
with graphical user interfaces. |
|
||||
|
|
||||
The full source code is available in the 'c-ares' release archives, and in a |
|
||||
git repository: http://github.com/bagder/c-ares |
|
||||
|
|
||||
If you find bugs, correct flaws, have questions or have comments in general in |
|
||||
regard to c-ares (or by all means the original ares too), get in touch with us |
|
||||
on the c-ares mailing list: http://cool.haxx.se/mailman/listinfo/c-ares |
|
||||
|
|
||||
c-ares is of course distributed under the same MIT-style license as the |
|
||||
original ares. |
|
||||
|
|
||||
You'll find all c-ares details and news here: |

|
||||
NOTES FOR C-ARES HACKERS |
|
||||
|
|
||||
The following notes apply to c-ares version 1.7.0 and later. |
|
||||
|
|
||||
* The distributed ares_build.h file is only intended to be used on systems |
|
||||
which can not run the also distributed configure script. |
|
||||
|
|
||||
* The distributed ares_build.h file is generated as a copy of ares_build.h.dist |
|
||||
when the c-ares source code distribution archive file is originally created. |
|
||||
|
|
||||
* If you check out from git on a non-configure platform, you must run the |
|
||||
appropriate buildconf* script to set up ares_build.h and other local files |
|
||||
before being able of compiling the library. |
|
||||
|
|
||||
* On systems capable of running the configure script, the configure process |
|
||||
will overwrite the distributed ares_build.h file with one that is suitable |
|
||||
and specific to the library being configured and built, this new file is |
|
||||
generated from the ares_build.h.in template file. |
|
||||
|
|
||||
* If you intend to distribute an already compiled c-ares library you _MUST_ |
|
||||
also distribute along with it the generated ares_build.h which has been |
|
||||
used to compile it. Otherwise the library will be of no use for the users of |
|
||||
the library that you have built. It is _your_ responsibility to provide this |
|
||||
file. No one at the c-ares project can know how you have built the library. |
|
||||
|
|
||||
* File ares_build.h includes platform and configuration dependent info, |
|
||||
and must not be modified by anyone. Configure script generates it for you. |
|
||||
|
|
||||
* We cannot assume anything else but very basic compiler features being |
|
||||
present. While c-ares requires an ANSI C compiler to build, some of the |
|
||||
earlier ANSI compilers clearly can't deal with some preprocessor operators. |
|
||||
|
|
||||
* Newlines must remain unix-style for older compilers' sake. |
|
||||
|
|
||||
* Comments must be written in the old-style /* unnested C-fashion */ |

c-ares |
|
||||
====== |
|
||||
|
|
||||
This package is based on ares 1.1.1 (written by Greg Hudson). I decided to |
|
||||
fork and release a separate project since the ares author didn't want the |
|
||||
improvements that were vital for our use of it. |
|
||||
|
|
||||
This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use |
|
||||
within the curl project (hence the letter C) and it makes a nice pun. Also, |
|
||||
c-ares is not API compatible with ares: a new name makes that more obvious to |
|
||||
the public. |
|
||||
|
|
||||
The original libares was distributed at athena-dist.mit.edu:pub/ATHENA/ares. |

How to build c-ares using MSVC or Visual Studio |
|
||||
================================================= |
|
||||
|
|
||||
|
|
||||
|
|
||||
How to build using MSVC from the command line |
|
||||
--------------------------------------------- |
|
||||
|
|
||||
Open a command prompt window and ensure that the environment is properly |
|
||||
set up in order to use MSVC or Visual Studio compiler tools. |
|
||||
|
|
||||
Change to c-ares source folder where Makefile.msvc file is located and run: |
|
||||
|
|
||||
> nmake -f Makefile.msvc |
|
||||
|
|
||||
This will build all c-ares libraries as well as three sample programs. |
|
||||
|
|
||||
Once the above command has finished a new folder named MSVCXX will exist |
|
||||
below the folder where makefile.msvc is found. The name of the folder |
|
||||
depends on the MSVC compiler version being used to build c-ares. |
|
||||
|
|
||||
Below the MSVCXX folder there will exist four folders named 'cares', |
|
||||
'ahost', 'acountry', and 'adig'. The 'cares' folder is the one that |
|
||||
holds the c-ares libraries you have just generated, the other three |
|
||||
hold sample programs that use the libraries. |
|
||||
|
|
||||
The above command builds four versions of the c-ares library, dynamic |
|
||||
and static versions and each one in release and debug flavours. Each |
|
||||
of these is found in folders named dll-release, dll-debug, lib-release, |
|
||||
and lib-debug, which hang from the 'cares' folder mentioned above. Each |
|
||||
sample program also has folders with the same names to reflect which |
|
||||
library version it is using. |
|
||||
|
|
||||
|
|
||||
How to install using MSVC from the command line |
|
||||
----------------------------------------------- |
|
||||
|
|
||||
In order to allow easy usage of c-ares libraries it may be convenient to |
|
||||
install c-ares libraries and header files to a common subdirectory tree. |
|
||||
|
|
||||
Once that c-ares libraries have been built using procedure described above, |
|
||||
use same command prompt window to define environment variable INSTALL_DIR |
|
||||
to designate the top subdirectory where installation of c-ares libraries and |
|
||||
header files will be done. |
|
||||
|
|
||||
> set INSTALL_DIR=c:\c-ares |
|
||||
|
|
||||
Afterwards, run following command to actually perform the installation: |
|
||||
|
|
||||
> nmake -f Makefile.msvc install |
|
||||
|
|
||||
Installation procedure will copy c-ares libraries to subdirectory 'lib' and |
|
||||
c-ares header files to subdirectory 'include' below the INSTALL_DIR subdir. |
|
||||
|
|
||||
When environment variable INSTALL_DIR is not defined, installation is done |
|
||||
to c-ares source folder where Makefile.msvc file is located. |
|
||||
|
|
||||
|
|
||||
How to build using Visual Studio 6 IDE |
|
||||
-------------------------------------- |
|
||||
|
|
||||
A VC++ 6.0 reference workspace (vc6aws.dsw) is available within the 'vc' |
|
||||
folder to allow proper building of the library and sample programs. |
|
||||
|
|
||||
1) Open the vc6aws.dsw workspace with MSVC6's IDE. |
|
||||
2) Select 'Build' from top menu. |
|
||||
3) Select 'Batch Build' from dropdown menu. |
|
||||
4) Make sure that the sixteen project configurations are 'checked'. |
|
||||
5) Click on the 'Build' button. |
|
||||
6) Once the sixteen project configurations are built you are done. |
|
||||
|
|
||||
Dynamic and static c-ares libraries are built in debug and release flavours, |
|
||||
and can be located each one in its own subdirectory, dll-debug, dll-release, |
|
||||
lib-debug and lib-release, all of them below the 'vc\cares' subdirectory. |
|
||||
|
|
||||
In the same way four executable versions of each sample program are built, |
|
||||
each using its respective library. The resulting sample executables are |
|
||||
located in its own subdirectory, dll-debug, dll-release, lib-debug and |
|
||||
lib-release, below the 'vc\acountry', 'vc\adig' and 'vc\ahost'folders. |
|
||||
|
|
||||
These reference VC++ 6.0 configurations are generated using the dynamic CRT. |
|
||||
|
|
||||
|
|
||||
How to build using Visual Studio 2003 or newer IDE |
|
||||
-------------------------------------------------- |
|
||||
|
|
||||
First you have to convert the VC++ 6.0 reference workspace and project files |
|
||||
to the Visual Studio IDE version you are using, following next steps: |
|
||||
|
|
||||
1) Open vc\vc6aws.dsw with VS20XX. |
|
||||
2) Allow VS20XX to update all projects and workspaces. |
|
||||
3) Save ALL and close VS20XX. |
|
||||
4) Open vc\vc6aws.sln with VS20XX. |
|
||||
5) Select batch build, check 'all' projects and click 'build' button. |
|
||||
|
|
||||
Same comments relative to generated files and folders as done above for |
|
||||
Visual Studio 6 IDE apply here. |
|
||||

Relationship between c-ares library file names and versions |
|
||||
----------------------------------------------------------- |
|
||||
|
|
||||
c-ares static release library version files: |
|
||||
|
|
||||
libcares.lib -> static release library |
|
||||
|
|
||||
c-ares static debug library version files: |
|
||||
|
|
||||
libcaresd.lib -> static debug library |
|
||||
|
|
||||
c-ares dynamic release library version files: |
|
||||
|
|
||||
cares.dll -> dynamic release library |
|
||||
cares.lib -> import library for the dynamic release library |
|
||||
cares.exp -> export file for the dynamic release library |
|
||||
|
|
||||
c-ares dynamic debug library version files: |
|
||||
|
|
||||
caresd.dll -> dynamic debug library |
|
||||
caresd.lib -> import library for the dynamic debug library |
|
||||
caresd.exp -> export file for the dynamic debug library |
|
||||
caresd.pdb -> debug symbol file for the dynamic debug library |
|
||||
|
|
||||
|
|
||||
How to use c-ares static libraries |
|
||||
---------------------------------- |
|
||||
|
|
||||
When using the c-ares static library in your program, you will have to |
|
||||
define preprocessor symbol CARES_STATICLIB while building your program, |
|
||||
otherwise you will get errors at linkage stage. |
|
||||

|
||||

||||
Have Fun! |

|
|

ares_reinit() |
|
||||
|
|
||||
- To allow an app to force a re-read of /etc/resolv.conf etc, pretty much |
|
||||
like the res_init() resolver function offers |
|
||||
|
|
||||
ares_gethostbyname |
|
||||
|
|
||||
- When built to support IPv6, it needs to also support PF_UNSPEC or similar, |
|
||||
so that an application can ask for any protocol and then c-ares would return |
|
||||
all known resolves and not just explicitly IPv4 _or_ IPv6 resolves. |
|
||||
|
|
||||
ares_process |
|
||||
|
|
||||
- Upon next ABI breakage ares_process() should be changed to return 'int' |
|
||||
and return ARES_ENOTINITIALIZED if ares_library_init() has not been called. |
|
||||
|
|
||||
ares_process_fd |
|
||||
|
|
||||
- Upon next ABI breakage ares_process_fd() should be changed to return |
|
||||
'int' and return ARES_ENOTINITIALIZED if library has not been initialized. |

* problem is elsewhere. It could be a problem in the ares_build.h |
|
||||
* header file, or simply that you are using different compilation |
|
||||
* settings than those used to build the library. |
|
||||
* |
|
||||
* Nothing in this file is intended to be modified or adjusted by the |
|
||||
* c-ares library user nor by the c-ares library builder. |
|
||||
* |
|
||||
* Do not deactivate any check, these are done to make sure that the |
|
||||
* library is properly built and used. |
|
||||
* |
|
||||
* You can find further help on the c-ares development mailing list: |

|
||||
* NOTE 2 |
|
||||
* ------ |
|
||||
* |
|
||||
* Some of the following compile time checks are based on the fact |
|
||||
* that the dimension of a constant array can not be a negative one. |
|
||||
* In this way if the compile time verification fails, the compilation |
|
||||
* will fail issuing an error. The error description wording is compiler |
|
||||
* dependent but it will be quite similar to one of the following: |
|
||||
* |
|
||||
* "negative subscript or subscript is too large" |
|
||||
* "array must have at least one element" |
|
||||
* "-1 is an illegal array size" |
|
||||
* "size of array is negative" |
|
||||
* |
|
||||
* If you are building an application which tries to use an already |
|
||||
* built c-ares library and you are getting this kind of errors on |
|
||||
* this file, it is a clear indication that there is a mismatch between |
|
||||
* how the library was built and how you are trying to use it for your |
|
||||
* application. Your already compiled or binary library provider is the |
|
||||
* only one who can give you the details you need to properly use it. |
