| 33 | This is the Boost 1.33 Serialization Library. |
|---|
| 34 | There are currently no known bugs. However, due to compiler/library quirks and or |
|---|
| 35 | bugs, some tests fail with some combinations of compilers and libraries. |
|---|
| 36 | <h2><a name="requirements"></a>Requirements</h2> |
|---|
| 37 | This library requires Boost version 1.33 or later. |
|---|
| 38 | <p> |
|---|
| 39 | The serialization library uses the boost spirit package to load XML archives. |
|---|
| 40 | We have found that all tests pass using spirit 1.6x. Spirit 1.8 and higher does not work with |
|---|
| 41 | older compilers - specificallly MSVC 6, Borland and GCC < 3.0. |
|---|
| 42 | If you are using one of these compilers, you may download a version |
|---|
| 43 | of spirit 1.6 <a href="http://spirit.sourceforge.net/index.php?doc=download/index.html">here</a>. |
|---|
| 44 | To use this downloaded version rather than the one included with boost, |
|---|
| 45 | set an environmental variable SPIRIT_ROOT to be equal to the root |
|---|
| 46 | directory where the downloaded copy of spirit has been placed. E. G. |
|---|
| 47 | <pre><code> |
|---|
| 48 | set SPIRIT_ROOT=c:/spirit16 |
|---|
| 49 | </code></pre> |
|---|
| 50 | If you're not using bjam and the Jamfile to build the library, be sure that |
|---|
| 51 | the directory which contains the version of spirit you plan to use is placed |
|---|
| 52 | at the front of the list of include paths. |
|---|
| 53 | |
|---|
| 54 | <h2><a name="recent_improvements"></a>Differences from Boost 1.32</h2> |
|---|
| 55 | <ul> |
|---|
| 56 | <li>Dynamic Linking Library (DLLs and shared libraries) for platforms which support them. See |
|---|
| 57 | <a href="../../../more/getting_started.html#auto-link">Automatic Linking on Windows</a>. |
|---|
| 58 | <li>Implementation of auto-link for compilers which can support this. |
|---|
| 59 | <li>Better support for <em>Argument Dependent Lookup</em> and two-phase lookup. |
|---|
| 60 | This results in simpler rules regarding the placing of serialization specializations |
|---|
| 61 | namespaces. |
|---|
| 62 | <li>Enhanced documentation to help explain usage of the above. |
|---|
| 63 | <li>Adjustments to improve support for less conformant compilers. |
|---|
| 64 | <li>Improved <code>const</code> correctness for save/load operators. Note that this may |
|---|
| 65 | produce compile time errors in code which compiled without problem in earlier boost releases. |
|---|
| 66 | In most cases the fix is trivial. In other cases, code should be scrutinized to be |
|---|
| 67 | sure that it doesn't use the serializaton system in a way which may introduce subtle bugs in |
|---|
| 68 | to the program. A fuller explanation of this issue can be found |
|---|
| 69 | <a target="detail" href="traits.html#tracking">here</a>. |
|---|
| 70 | <li>A new implementation of serialization for <code style="white-space: normal">shared_ptr<T></code>. This |
|---|
| 71 | is compatible with public interface of <code style="white-space: normal">shared_ptr<T></code> |
|---|
| 72 | so it should be more robust and not have to change in the future. The implementation optionally |
|---|
| 73 | includes code to load <code style="white-space: normal">shared_ptr<T></code> stored in |
|---|
| 74 | archives created with boost 1.32. This code is stored in the header: |
|---|
| 75 | <code style="white-space: normal">boost/serialization/shared_ptr_132.hpp</code>. If your application |
|---|
| 76 | needs to load archives created with boost 1.32 libraries, include the above header |
|---|
| 77 | before each inclusion of <code style="white-space: normal">boost/serialization/shared_ptr.hpp</code>. |
|---|
| 78 | <li>More compilers tested and supported. |
|---|
| 79 | <li>Miscelleanous bug fixes. |
|---|
| 80 | </ul> |
|---|
| 81 | |
|---|
| 82 | <h2><a name="todo"></a>Pending issues</h2> |
|---|
| 83 | <ul> |
|---|
| 84 | <li>Compile, and test on more platforms |
|---|
| 85 | <li>implement <code>is_virtual_base<T></code> to automatically |
|---|
| 86 | eliminate redundancy in virtual base class serialization. |
|---|
| 87 | <li>currently can't serialize through a pointer an object a of class |
|---|
| 88 | that implements its own <code style="white-space: normal">new/delete</code> operators. |
|---|
| 89 | <li>Its possible that <code style="white-space: normal">std::string</code> |
|---|
| 90 | and <code style="white-space: normal">std::wstring</code> contain characters such as |
|---|
| 91 | '\0' which cannot be rendered in XML without an escape mechanism. Currently there is |
|---|
| 92 | no such escape mechanism implemented. |
|---|
| 93 | <li>A subtle error in the implementation of serialiaton of <code style="white-space: normal">std::map</code> |
|---|
| 94 | is fixed in this version. Unfortunately, the fix breaks serialization of |
|---|
| 95 | <code style="white-space: normal">std::map</code> for those compilers which do not support |
|---|
| 96 | partial template specialization. |
|---|
| 97 | </ul> |
|---|
| 98 | <p> |
|---|
| 99 | Aside from the above, there are a number of issus related to specific platforms. |
|---|
| 100 | These are listed in <a href="implementation.html#othercompilerissues">Specific Compiler/Library Issues</a>. |
