            <title>[GODRIVER-2687] Deprecate &quot;NewTagSetFromMap&quot; and &quot;NewTagSetsFromMaps&quot; in tags package</title>
                <link>https://jira.mongodb.org/browse/GODRIVER-2687</link>
                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;p&gt;The &lt;tt&gt;NewTagSetFromMap&lt;/tt&gt; and &lt;tt&gt;NewTagSetsFromMaps&lt;/tt&gt; functions may mislead users into expecting that the ordered &lt;tt&gt;tag.Set&lt;/tt&gt; type can be created from a Go &lt;tt&gt;map&lt;/tt&gt;, when in fact the resulting &lt;tt&gt;tag.Set&lt;/tt&gt; has a non-deterministic order. Deprecate those functions in preparation for them to be removed with v2.0.&lt;/p&gt;

&lt;p&gt;Note that users can safely define ordered tag sets using a syntax like&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;set := tag.Set{{Name: &quot;name&quot;, Value: &quot;value&quot;}, ...}&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;However, that&apos;s a bit verbose for longer tag sets, so we should consider adding a convenience function that takes in a list of tag tuples and creates a &lt;tt&gt;Set&lt;/tt&gt;, returning an error if the list length is odd.&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;func ToSet(tags ...string) (Set, error)&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;Since that requires users to handle errors, and we typically expect users to define this statically in code, we should also consider adding a shorter convenience function that panics on any errors (inspired by Go&apos;s &lt;a href=&quot;https://pkg.go.dev/html/template#Must&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;template.Must&lt;/a&gt;).&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;func Must(Set, error) Set&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Definition of done:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Deprecate &lt;tt&gt;NewTagSetFromMap&lt;/tt&gt; and &lt;tt&gt;NewTagSetsFromMaps&lt;/tt&gt;&lt;/li&gt;
	&lt;li&gt;Consider adding convenience functions for creating a &lt;tt&gt;Set&lt;/tt&gt;&lt;/li&gt;
&lt;/ul&gt;

                            <comment id="5383024" author="JIRAUSER1259527" created="Thu, 27 Apr 2023 22:08:54 +0000"  >&lt;p&gt;Actually, there&apos;s nothing to fix here! Tag sets, which are sets of key/value pairs, are not order-dependent. Tag set &lt;em&gt;lists&lt;/em&gt; are order dependent, but the Go Driver tags APIs always use ordered types, so there shouldn&apos;t be issues.&lt;/p&gt;

&lt;p&gt;The tag filtering documentation, both in the &lt;tt&gt;readpref&lt;/tt&gt; and &lt;tt&gt;tag&lt;/tt&gt; packages, could be better. However, I&apos;m closing this ticket as there&apos;s nothing we need to deprecate.&lt;/p&gt;</comment>
