|
INTRODUCTION
|
|
|
|
<a id="intro" name="intro">.intro</a>: This describes the design of a mechanism to be used to determine the
|
|
version (that is, product, version, and release) of an MPS library.
|
|
|
|
|
|
READERSHIP
|
|
|
|
<a id="readership" name="readership">.readership</a>: Any MPS developer.
|
|
|
|
|
|
SOURCE
|
|
|
|
<a id="source" name="source">.source</a>: Various requirements demand such a mechanism. See
|
|
request<a id="epcore.160021" name="epcore.160021">.epcore.160021</a>: There is no way to tell which version and release of the
|
|
MM one is using.
|
|
|
|
|
|
OVERVIEW
|
|
|
|
<a id="overview" name="overview">.overview</a>: See design.mps.version for discussion and design of versions of
|
|
other aspects of the software. This document concentrates on a design for
|
|
determining which version of the library one has linked with. There are two
|
|
aspects to the design, allowing humans to determine the version of an MPS
|
|
library, and allowing programs to determine the version of an MPS library.
|
|
Only the former is currently designed (a method for humans to determine which
|
|
version of an MPS library is being used).
|
|
|
|
<a id="overview.impl" name="overview.impl">.overview.impl</a>: The overall design is to have a distinctive string compiled
|
|
into the library binary. Various programs and tools will be able to extract
|
|
the string and display it. The string will identify the version of the MPS
|
|
begin used.
|
|
|
|
|
|
ARCHITECTURE
|
|
|
|
<a id="arch.structure" name="arch.structure">.arch.structure</a>: The design consists of 3 components:
|
|
|
|
<a id="arch.string" name="arch.string">.arch.string</a>: A string embedded into any delivered library binaries (which will
|
|
encode the necessary information).
|
|
|
|
<a id="arch.proc" name="arch.proc">.arch.proc</a>: A process by which the string is modified appropriately whenever
|
|
releases are made.
|
|
|
|
<a id="arch.tool" name="arch.tool">.arch.tool</a>: A tool and its documentation (it is expected that standard tools
|
|
can be used). The tool will be used to extract the version string from a
|
|
delivered library or an executable linked with the library.
|
|
|
|
<a id="arch.not-here" name="arch.not-here">.arch.not-here</a>: Only the string component (:arch.string) is directly described
|
|
here. The other components are described elsewhere. (where?)
|
|
|
|
The string will contain information to identify the following items:
|
|
<a id="arch.string.platform" name="arch.string.platform">.arch.string.platform</a>: the platform being used.
|
|
<a id="arch.string.product" name="arch.string.product">.arch.string.product</a>: the name of the product.
|
|
<a id="arch.string.variety" name="arch.string.variety">.arch.string.variety</a>: the variety of the product.
|
|
<a id="arch.string.version" name="arch.string.version">.arch.string.version</a>: the version and release of the product.
|
|
|
|
|
|
IMPLEMENTATION
|
|
|
|
<a id="impl.file" name="impl.file">.impl.file</a>: The string itself is a declared C object in the file version.c
|
|
(impl.c.version). It consists of a concatenation of various strings which are
|
|
defined in other modules.
|
|
|
|
<a id="impl.variety" name="impl.variety">.impl.variety</a>: The string containing the name of the variety is the expansion
|
|
of the macro MPS_VARIETY_STRING defined by config.h (impl.h.config).
|
|
|
|
<a id="impl.product" name="impl.product">.impl.product</a>: The string containing the name of the product is the expansion
|
|
of the macro MPS_PROD_STRING defined by config.h (impl.h.config).
|
|
|
|
<a id="impl.platform" name="impl.platform">.impl.platform</a>: The string containing the name of the platform is the expansion
|
|
of the macro MPS_PF_STRING defined by mpstd.h (impl.h.mpstd).
|
|
|
|
<a id="impl.date" name="impl.date">.impl.date</a>: The string contains the date and time of compilation by using the
|
|
__DATE__ and __TIME__ macros defined by ISO C (ISO C clause 6.8.8).
|
|
|
|
<a id="impl.version" name="impl.version">.impl.version</a>: The string contains the version and release of the product.
|
|
This is by the expansion of the macro MPS_RELEASE which is defined in this
|
|
module (version.c).
|
|
|
|
<a id="impl.usage" name="impl.usage">.impl.usage</a>: To make a release, the MPS_RELEASE macro (see
|
|
impl.c.version.release) is edited to contain the release name (e.g.,
|
|
"release.epcore.brisling"), and then changed back immediately after the release
|
|
checkpoint is made.
