Git does not support the ability to replace a token with a version string during check-in. While it does have support for replacing a token on clone, this is somewhat sub-optimal: the token is replaced with the object hash, which is not particularly easy for human consumption. What's more, in practice, the source file version was often not terribly useful. Generally, when triaging bugs, the overall version of Asterisk is far more useful than an individual SVN version of a file. As a result, this patch removes Asterisk's support for showing source file versions. Specifically, it does the following: * Rename ASTERISK_FILE_VERSION macro to ASTERISK_REGISTER_FILE, and remove passing the version in with the macro. Other facilities than 'core show file version' make use of the file names, such as setting a debug level only on a specific file. As such, the act of registering source files with the Asterisk core still has use. The macro rename now reflects the new macro purpose. * main/asterisk: - Refactor the file_version structure to reflect that it no longer tracks a version field. - Remove the "core show file version" CLI command. Without the file version, it is no longer useful. - Remove the ast_file_version_find function. The file version is no longer tracked. - Rename ast_register_file_version/ast_unregister_file_version to ast_register_file/ast_unregister_file, respectively. * main/manager: Remove value from the Version key of the ModuleCheck Action. The actual key itself has not been removed, as doing so would absolutely constitute a backwards incompatible change. However, since the file version is no longer tracked, there is no need to attempt to include it in the Version key. * UPGRADE: Add notes for: - Modification to the ModuleCheck AMI Action - Removal of the "core show file version" CLI command Change-Id: I6cf0ff280e1668bf4957dc21f32a5ff43444a40e

<para>The calling extension, context, and priority are stored in <variable>MACRO_EXTEN</variable>,
|
|
<variable>MACRO_CONTEXT</variable> and <variable>MACRO_PRIORITY</variable> respectively. Arguments
|

become <variable>ARG1</variable>, <variable>ARG2</variable>, etc in the macro context.</para>

<para>If you Goto out of the Macro context, the Macro will terminate and control will be returned

at priority MACRO_OFFSET + N + 1 if such a step exists, and N + 1 otherwise.</para>
|
|
<warning><para>Because of the way Macro is implemented (it executes the priorities contained within
|
|
it via sub-engine), and a fixed per-thread memory stack allowance, macros are limited to 7 levels
|
|
of nesting (macro calling macro calling macro, etc.); It may be possible that stack-intensive
|
|
applications in deeply nested macros could cause asterisk to crash earlier than this limit.
|
|
It is advised that if you need to deeply nest macro calls, that you use the Gosub application
|
|
(now allows arguments like a Macro) with explict Return() calls instead.</para></warning>
|
|
<warning><para>Use of the application <literal>WaitExten</literal> within a macro will not function
|
|
as expected. Please use the <literal>Read</literal> application in order to read DTMF from a channel
|
|
currently executing a macro.</para></warning>
