These limits mainly concern data that is <a href="/wiki/Wikipedia:Transclusion" class="mw-redirect" title="Wikipedia:Transclusion">transcluded</a> or <a href="/wiki/Wikipedia:Substitution" title="Wikipedia:Substitution">substituted</a> during expansion of a page, as opposed to data directly in the source of the page itself. This page explains how and why these limits are applied, and how users can work within the limits. </p> <meta property="mw:PageProp/toc"/> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Background" data-mw-thread-id="h-Background"><span data-mw-comment-start="" id="h-Background"></span>Background<span data-mw-comment-end="h-Background"></span></h2></div> <div class="mw-heading mw-heading3"><h3 id="What_is_this_about?" data-mw-thread-id="h-What_is_this_about?-Background"><span id="What_is_this_about.3F"></span><span data-mw-comment-start="" id="h-What_is_this_about?-Background"></span>What is this about?<span data-mw-comment-end="h-What_is_this_about?-Background"></span></h3></div> <p>The <a href="/wiki/MediaWiki" title="MediaWiki">MediaWiki</a> software, which generates the <a href="/wiki/HTML" title="HTML">HTML</a> of a page from its wiki source, uses a <a href="/wiki/Parser" class="mw-redirect" title="Parser">parser</a> to deal with included data. This is done using a "preprocessor" which converts the wikitext into a data structure known as an XML tree, and then uses this tree to produce "<a href="https://meta.wikimedia.org/wiki/Help:Expansion" class="extiw" title="m:Help:Expansion">expanded</a>" wikitext, where double- and triple-braced structures are replaced by their result. </p><p>During the conversion process, the software uses several counters to track the complexity of the page that is being generated. When the <a href="/wiki/Parsing" title="Parsing">parsing</a> of a page begins, these counters are set to zero, but they are incremented during the parsing process, as described below. There are upper limits on these counters, and the parser does not allow these limits to be exceeded. </p> <div class="mw-heading mw-heading3"><h3 id="Why_are_there_limits?" data-mw-thread-id="h-Why_are_there_limits?-Background"><span id="Why_are_there_limits.3F"></span><span data-mw-comment-start="" id="h-Why_are_there_limits?-Background"></span>Why are there limits?<span data-mw-comment-end="h-Why_are_there_limits?-Background"></span></h3></div> <p>Very long or complicated pages are slow to <a href="/wiki/Parsing" title="Parsing">parse</a>. Not only is this an inconvenience for users, but it can also be used to mount a <a href="/wiki/Denial-of-service_attack" title="Denial-of-service attack">denial of service (DoS) attack</a> on the servers, in which a page request forces the MediaWiki software to parse an unreasonably large quantity of data. The limits help to prevent this kind of attack, and ensure that pages are rendered in a reasonable time. (Nevertheless, sometimes a complex page within the limits gives a time-out error; this depends on how busy the servers are.) </p> <div class="mw-heading mw-heading3"><h3 id="Working_within_the_limits" data-mw-thread-id="h-Working_within_the_limits-Background"><span data-mw-comment-start="" id="h-Working_within_the_limits-Background"></span>Working within the limits<span data-mw-comment-end="h-Working_within_the_limits-Background"></span></h3></div> <p>When a page reaches the template limits, the most common solution is to make the templates shorter, using methods described below. If this isn't possible, it may be necessary to include more data directly in the page source, rather than transcluding it from templates (e.g., formatting references by hand or using <code><references /></code> instead of <span class="nowrap">{{</span><a href="/wiki/Template:Reflist" title="Template:Reflist">Reflist</a><span class="nowrap">}}</span>). On the other hand, a template can help the server avoid doing duplicate work, see below. </p> <div class="mw-heading mw-heading3"><h3 id="When_do_problems_arise?" data-mw-thread-id="h-When_do_problems_arise?-Background"><span id="When_do_problems_arise.3F"></span><span data-mw-comment-start="" id="h-When_do_problems_arise?-Background"></span>When do problems arise?<span data-mw-comment-end="h-When_do_problems_arise?-Background"></span></h3></div> <style data-mw-deduplicate="TemplateStyles:r1236090951">.mw-parser-output .hatnote{font-style:italic}.mw-parser-output div.hatnote{padding-left:1.6em;margin-bottom:0.5em}.mw-parser-output .hatnote i{font-style:normal}.mw-parser-output .hatnote+link+.hatnote{margin-top:-0.5em}@media print{body.ns-0 .mw-parser-output .hatnote{display:none!important}}</style><div role="note" class="hatnote navigation-not-searchable">See also: <a href="/wiki/Help:Template#Expand_limits" title="Help:Template">Help:Template § Expand limits</a></div> <p>The inclusion limits are most commonly reached on pages that use the same template many times, for example using one transclusion per row of a long table. Even though the amount of data that the template adds to the final page may be small, it is counted each time the template is used, and so the limit may be encountered sooner than expected. Pages that only include a few dozen templates are unlikely to exceed the inclusion limits, unless these templates themselves include a lot of data. </p> <div class="mw-heading mw-heading3"><h3 id="How_can_you_find_out?" data-mw-thread-id="h-How_can_you_find_out?-Background"><span id="How_can_you_find_out.3F"></span><span data-mw-comment-start="" id="h-How_can_you_find_out?-Background"></span>How can you find out?<span data-mw-comment-end="h-How_can_you_find_out?-Background"></span></h3></div> <p>Once the page body is processed, an HTML comment is added towards the end of the HTML code of the page with the final values of the various counters. For example, the page <a href="/wiki/HIV/AIDS" title="HIV/AIDS">HIV/AIDS</a> (on January 1, 2024) contains the following comment in its generated HTML source: </p> <div class="mw-highlight mw-highlight-lang-html mw-content-ltr" dir="ltr"><pre><span></span><span class="cm"></span> </pre></div> <p>(Some items may not be present on other wikis, depending on which extensions they have installed; for example, the "Lua" items are added by <a href="https://www.mediawiki.org/wiki/Extension:Scribunto" class="extiw" title="mw:Extension:Scribunto">Extension:Scribunto</a>.) </p><p>Because of the way the counters are increased, the preprocessor visited node count, post-expand include size, and template argument size will usually be less than their limits. If any of these items are close to their limit, then it is likely that some of the templates have not been expanded. Each occurrence of an unexpanded template is identified in the page body by an HTML comment containing an error message. </p><p>Click "Parser profiling data" at the bottom of a preview to see similar data for the preview without saving it. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Expansion" data-mw-thread-id="h-Expansion"><span data-mw-comment-start="" id="h-Expansion"></span>Expansion<span data-mw-comment-end="h-Expansion"></span></h2></div> <p>Templates in non-executed branches of conditional parser functions are not expanded, and therefore not counted. For example, in the code <code>{{#if:yes|{{bar}}|{{foo}}}}</code>, the template <code>{{bar}}</code> is expanded, but the template <code>{{foo}}</code> is not expanded. Nevertheless, it is possible for a template argument to contribute to the counts even though it does not appear in the final output. For example, if the code <code>{{#if:{{foo}}|yes|no}}</code> is parsed, the length of the expanded version of template <code>{{foo}}</code> will be added to the post-expand counter, because that template must be expanded to decide which branch of the conditional should be selected. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Preprocessor_node_count" data-mw-thread-id="h-Preprocessor_node_count"><span data-mw-comment-start="" id="h-Preprocessor_node_count"></span>Preprocessor node count<span data-mw-comment-end="h-Preprocessor_node_count"></span></h2></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">See also: <a href="https://www.mediawiki.org/wiki/Manual:$wgMaxPPNodeCount" class="extiw" title="mw:Manual:$wgMaxPPNodeCount">mw:Manual:$wgMaxPPNodeCount</a></div> <p>The <b>preprocessor node count</b> measures the complexity of the page (not the volume of data). As the parser is expanding a page, it creates a data structure known as a tree that corresponds to the HTML structure of the page. Each node of the tree that is visited during expansion is counted towards the preprocessor node count. If this count is exceeded, the parser will abort parsing with the error "Node-count limit exceeded" visible in the generated HTML. </p><p>The count starts with 1 for plain text. A pair of nowiki tags counts for 3, a header for 2, etc. A link does not contribute to the count. For the expansion of <code>#switch</code> every checked condition adds 2 to the count. In the case of multiple expansions of the same template the content of a template without arguments counts only once, but that of a template with arguments (even if constant) counts multiple times. In contrast to this, the result of an expansion can be used multiple times while counting only once if it is assigned to a template parameter, and that template has multiple uses of this parameter. </p><p>Pages exceeding this limit are automatically categorized into <a href="/wiki/Category:Pages_where_node_count_is_exceeded" title="Category:Pages where node count is exceeded">Category:Pages where node count is exceeded</a> (<a class="external text" href="https://en.wikipedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Category%3APages%20where%20node%20count%20is%20exceeded&cmprop=title%7Ctimestamp&cmlimit=500&cmsort=timestamp&cmdir=desc&format=xml">recent additions</a>). </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Post-expand_include_size" data-mw-thread-id="h-Post-expand_include_size"><span data-mw-comment-start="" id="h-Post-expand_include_size"></span>Post-expand include size<span data-mw-comment-end="h-Post-expand_include_size"></span></h2></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1252059228"><div class="module-shortcutanchordiv"><span id="WP:PEIS"></span></div><div class="module-shortcutboxplain noprint" role="note"><div class="module-shortcutlist"><a href="/wiki/Wikipedia:Shortcut" title="Wikipedia:Shortcut">Shortcut</a></div><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1126788409"><div class="plainlist"><ul><li><span class="plainlinks"><a class="external text" href="https://en.wikipedia.org/w/index.php?title=Wikipedia:PEIS&redirect=no">WP:PEIS</a></span></li></ul></div></div> <p>The <b>post-expand include size</b> is the sum of the lengths of the expanded wikitexts generated by templates, parser functions and variables. Whenever the parser is instructed by the source code of a page to expand a template etc. (that is, to replace it by transclusion or substitution), the parser adds together the length of the expanded wikitext generated by the template etc. and the current counter value of the page. If this sum is more than the <b>post-expand limit</b> (same as the <a href="/wiki/Wikipedia:CHOKING" class="mw-redirect" title="Wikipedia:CHOKING">max article size limit</a>), the initial template etc. is not replaced and an error message is added as a comment in the output HTML. Otherwise the post-expand counter is increased to the new value, and parsing continues. A template that is expanded more than once in the page contributes more than once to its post-expand include size. </p><p>Template invocations with no arguments have an expanded text cache. So if <code>{{foo}}</code> includes the second-level meta-template <code>{{bar}}</code>, then multiple invocations of <code>{{foo}}</code> will only increment the post-expand include size for the fully-expanded <code>{{foo}}</code>; the secondary include <code>{{bar}}</code> is only counted once. But if you included the same template multiple times with <code>{{foo|arg}}</code>, then the secondary templates are counted each time, even if the argument is the same. </p><p>Pages exceeding the post-expand include size limit are automatically added to <a href="/wiki/Category:Pages_where_post-expand_include_size_is_exceeded" title="Category:Pages where post-expand include size is exceeded">Category:Pages where post-expand include size is exceeded</a> (<a class="external text" href="https://en.wikipedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Category%3APages+where+post-expand+include+size+is+exceeded&cmprop=title%7Ctimestamp&cmlimit=500&cmsort=timestamp&cmdir=desc&format=xml">recent additions</a>). <a href="/wiki/Template:Citations_broken_from_PEIS_limit" title="Template:Citations broken from PEIS limit">Template:Citations broken from PEIS limit</a> may be manually added to the page when citations or templates are broken as a result of the issue.
