| This chapter lists any compatibility issues with prior versions of
| |
| the <var class="product">Sirius Mods</var> and any bugs which have been fixed in this version of
| |
| the <var class="product">Sirius Mods</var> but had not, as of the date of this release, been fixed
| |
| in the previous generally available version (7.7).
| |
|
| |
| In general, backward incompatibility means that an operation which was
| |
| previously performed without any indication of error, now operates, given
| |
| the same inputs and conditions, in a different manner.
| |
| We may not list as backwards incompatibilities those cases in which the
| |
| previous behaviour, although not indicating an error, was “clearly and
| |
| obviously” incorrect, and which are introduced as normal bug fixes
| |
| (whether or not they had been fixed with previous maintenance).
| |
|
| |
| ==Backwards incompatibilities==
| |
| Backwards incompatibilities are described per product in the following sections.
| |
| ===Janus SOAP XmlDoc API===
| |
| The following backwards compatibility issues have been introduced in the
| |
| <var class="product">Janus SOAP</var> [[XmlDoc API]].
| |
| ====AddToRecord constraint on "number" attribute====
| |
| As described in [[Janus SOAP XmlDoc API V7.8 changes#Structure of XmlDoc for AddToRecord|"Structure of XmlDoc for AddToRecord"]], if the "number" attribute of the "Record" element in the input <var>XmlDoc</var> of the <var>AddToRecord</var> subroutine is present, it must be an integer greater than or equal to -1.
| |
|
| |
| Previously, this attribute was ignored.
| |
| ====DefaultURI argument of AddSubtree====
| |
| In some cases, an Element in a default namespace, which was
| |
| added to the <var>XmlDoc</var> by a deserialization method, will not get the
| |
| correct namespace URI when it is copied using the <var>DefaultURI</var>
| |
| argument of the <var>AddNamespace</var> subroutine.
| |
|
| |
| Note that this problem was also fixed (with the resulting
| |
| incompatibility) in the version 7.7 <var class="product">Sirius Mods</var> by maintenance
| |
| supplied by ZAP77A4 on 17 August, 2010.
| |
|
| |
| For example:
| |
| <p class="code"><nowiki>Text To %sl
| |
| <a:a xmlns:a="http://aaa" xmlns="http://ddd">
| |
| <b:b xmlns:b="http://bbb">
| |
| <c>123</c>
| |
| </b:b>
| |
| </a:a>
| |
| End Text
| |
| %in:LoadXml(%sl)
| |
| %n Object XmlNode
| |
| %n = %in:SelectSingleNode('/*/*')
| |
| %out:AddSubtree(%n, DefaultURI='u:who')
| |
| </nowiki></p>
| |
| Prior to fixing this problem, the above results in:
| |
| <p class="output"><nowiki><b:b xmlns:b="http://bbb">
| |
| <c xmlns="http://ddd">
| |
| 123
| |
| </c>
| |
| </b:b>
| |
| </nowiki></p>
| |
| The correct result, as produced by version 7.8 of the <var class="product">Sirius Mods</var> or
| |
| version 7.7 with with ZAP77A4 applied,
| |
| is as follows (note the namespace for element <code>c</code>):
| |
| <p class="output"><nowiki><b:b xmlns:b="http://bbb">
| |
| <c xmlns="u:who">
| |
| 123
| |
| </c>
| |
| </b:b>
| |
| </nowiki></p>
| |
| ====Deserialization prohibits default namespace declaration with Namespace=None====
| |
| With the <var>XmlDoc</var> <var>[[Namespace (XmlDoc property)|Namespace]]</var> property set to <var>None</var>, namespace declarations that bind a
| |
| prefix are not allowed. For example:
| |
| <p class="code"><nowiki><foo xmlns:p="http://p.com/>
| |
| </nowiki></p>
| |
| The above has never been allowed, due to the prohibition against colons in XML
| |
| names when <var>Namespace</var> is <var>None</var>.
| |
|
| |
| However, previous versions of the <var class="product">Sirius Mods</var> allowed deserialization of a
| |
| default namespace declaration. For example:
| |
| <p class="code"><nowiki><foo xmlns="http://p.com/>
| |
| </nowiki></p>
| |
| The above was erroneously treated as if <code>xmlns</code> were an attribute.
| |
|
| |
| Deserialization of default namespace declarations is no longer allowed.
| |
|
| |
| This fix was also introduced in version 7.7 of the <var class="product">Sirius Mods</var>, via ZAP77B2.
| |
|
| |
| ===Janus SOAP ULI===
| |
|
| |
| ====Unspace method now converts all-whitespace string to null====
| |
| Prior to Version 7.8 of the <var class="product">Sirius Mods</var>, the intrinsic <var>String</var> <var>[[Unspace (String function)|Unspace]]</var> method compressed a string consisting entirely of whitespace characters to a single whitespace character.
| |
| For example, note the single blank in the result of <code>PrintText {~} = X{' ':unspace}X</code>:
| |
| <p class="output"><nowiki>' ':unspace = X X
| |
| </nowiki></p>
| |
| In version 7.8 (and also in <var class="product">Sirius Mods</var> version 7.7 via ZAP7761), <var>Unspace</var> converts a string of whitespace characters to the null string. After this fix is in effect, the <var>[[Targeted Text statements|PrintText]]</var> statement above produces a null string:
| |
| <p class="output"><nowiki>' ':unspace = XX
| |
| </nowiki></p>
| |
| ==Fixes in <var class="product">Sirius Mods</var> 7.8 but not in 7.7==
| |
| This section lists fixes to functionality
| |
| existing in the <var class="product">Sirius Mods</var> version
| |
| 7.7 but which, due to the absence of customer problems, have not, as of the date
| |
| of the release, been fixed in that version.
| |
|
| |
| ===LoadSystemMethodInfo returning Unicode methods===
| |
| The <var>[[LoadSystemMethodInfo (XmlDoc subroutine)|LoadSystemMethodInfo]]</var> now returns information for <var>Unicode</var> intrinsic methods.
| |
| ===Fast/Reload LAI with various UAI SORT cases===
| |
| The following two bugs have been fixed:
| |
| <ul>
| |
| <li>Possible use of <var>UAI SORT</var> key as hashed file sort key.
| |
| <p>
| |
| For example, the following code (incorrectly) completes without any indication of error in <var class="product">Sirius Mods</var> 7.7, but in 7.8 it is flagged as an error:</p>
| |
| <p class="code"><nowiki>* Fast/Unload step:
| |
| UAI SORT FOO LENGTH 3 TRUNC
| |
| ...
| |
| * Fast/Reload step:
| |
| CREATE FILE (NOFORMAT) QAWORK
| |
| PARAMETER FILEORG 8
| |
| END
| |
| OPEN QAWORK
| |
| *UPDATE
| |
| IN QAWORK INITIALIZE
| |
| HASH FOO
| |
| FILELOAD -1,-1,0,3000000,10000,10000,10000,32
| |
| LAI
| |
| </nowiki></p>
| |
|
| |
| <li>A spurious error ("TAPEI format error" or unkown field) is issued
| |
| if the first <var>UAI SORT</var> item is a <var class="product">FUEL</var> %variable, and the subsequent <var>LAI</var>
| |
| is loaded into a non-sort, non-hash file.
| |
| Note that the <var class="product">[[Fast/Unload]]</var> <var>UAI</var> output file must also contain the correct value
| |
| to fix this bug; with version 4.4 of <var class="product">Fast/Unload</var>, ZAP4414 is required, with
| |
| version 4.5, ZAP4518 is required.
| |
| </ul>
| |
| | |
| ==Version corequisites==
| |
| This section lists any restrictions on usage of various products
| |
| (including <var class="product">Sirius Mods</var> itself) that will be imposed by use of version 7.8
| |
| of <var class="product">Sirius Mods</var>.
| |
|
| |
| <ul>
| |
| <li>There are no corequisites associated with <var class="product">Sirius Mods</var> 7.8.
| |
| </ul>
