* all: Rework page store, add a dynacache, improve partial rebuilds, and some ↵develop2024Bjørn Erik Pedersen2024-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | general spring cleaning There are some breaking changes in this commit, see #11455. Closes #11455 Closes #11549 This fixes a set of bugs (see issue list) and it is also paying some technical debt accumulated over the years. We now build with Staticcheck enabled in the CI build. The performance should be about the same as before for regular sized Hugo sites, but it should perform and scale much better to larger data sets, as objects that uses lots of memory (e.g. rendered Markdown, big JSON files read into maps with transform.Unmarshal etc.) will now get automatically garbage collected if needed. Performance on partial rebuilds when running the server in fast render mode should be the same, but the change detection should be much more accurate. A list of the notable new features: * A new dependency tracker that covers (almost) all of Hugo's API and is used to do fine grained partial rebuilds when running the server. * A new and simpler tree document store which allows fast lookups and prefix-walking in all dimensions (e.g. language) concurrently. * You can now configure an upper memory limit allowing for much larger data sets and/or running on lower specced PCs. We have lifted the "no resources in sub folders" restriction for branch bundles (e.g. sections). Memory Limit * Hugos will, by default, set aside a quarter of the total system memory, but you can set this via the OS environment variable HUGO_MEMORYLIMIT (in gigabytes). This is backed by a partitioned LRU cache used throughout Hugo. A cache that gets dynamically resized in low memory situations, allowing Go's Garbage Collector to free the memory. New Dependency Tracker: Hugo has had a rule based coarse grained approach to server rebuilds that has worked mostly pretty well, but there have been some surprises (e.g. stale content). This is now revamped with a new dependency tracker that can quickly calculate the delta given a changed resource (e.g. a content file, template, JS file etc.). This handles transitive relations, e.g. $page -> js.Build -> JS import, or $page1.Content -> render hook -> site.GetPage -> $page2.Title, or $page1.Content -> shortcode -> partial -> site.RegularPages -> $page2.Content -> shortcode ..., and should also handle changes to aggregated values (e.g. site.Lastmod) effectively. This covers all of Hugo's API with 2 known exceptions (a list that may not be fully exhaustive): Changes to files loaded with template func os.ReadFile may not be handled correctly. We recommend loading resources with resources.Get Changes to Hugo objects (e.g. Page) passed in the template context to lang.Translate may not be detected correctly. We recommend having simple i18n templates without too much data context passed in other than simple types such as strings and numbers. Note that the cachebuster configuration (when A changes then rebuild B) works well with the above, but we recommend that you revise that configuration, as it in most situations should not be needed. One example where it is still needed is with TailwindCSS and using changes to hugo_stats.json to trigger new CSS rebuilds. Document Store: Previously, a little simplified, we split the document store (where we store pages and resources) in a tree per language. This worked pretty well, but the structure made some operations harder than they needed to be. We have now restructured it into one Radix tree for all languages. Internally the language is considered to be a dimension of that tree, and the tree can be viewed in all dimensions concurrently. This makes some operations re. language simpler (e.g. finding translations is just a slice range), but the idea is that it should also be relatively inexpensive to add more dimensions if needed (e.g. role).

* parser/pageparser: Don't store the byte slicesBjørn Erik Pedersen2022-07-09
| | | | | On its own this change doesn't do any magic, but this is part of a bigger picture about making Hugo leaner in the memory usage department.

* Fix handling of HTML files without front matterBjørn Erik Pedersen2020-03-09
| | | | | | | | | | | | | | | | | This means that any HTML file inside /content will be treated as a regular file. If you want it processes with shortcodes and a layout, add front matter. The defintion of an HTML file here is: * File with extension .htm or .html * With first non-whitespace character "<" that isn't a HTML comment. This is in line with the documentation. Fixes #7030 Fixes #7028 See #6789
* Support typed bool, int and float in shortcode paramsBjørn Erik Pedersen2019-09-29
| | | | | | | | | | | | | | This means that you now can do: {{< vidur 9KvBeKu false true 32 3.14 >}} And the boolean and numeric values will be converted to `bool`, `int` and `float64`. If you want these to be strings, they must be quoted: {{< vidur 9KvBeKu "false" "true" "32" "3.14" >}} Fixes #6371
* Move the emoji parsing to pageparserBjørn Erik Pedersen2018-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids double parsing the page content when `enableEmoji=true`. This commit also adds some general improvements to the parser, making it in general much faster: ```bash benchmark old ns/op new ns/op delta BenchmarkShortcodeLexer-4 90258 101730 +12.71% BenchmarkParse-4 148940 15037 -89.90% benchmark old allocs new allocs delta BenchmarkShortcodeLexer-4 456 700 +53.51% BenchmarkParse-4 28 33 +17.86% benchmark old bytes new bytes delta BenchmarkShortcodeLexer-4 69875 81014 +15.94% BenchmarkParse-4 8128 8304 +2.17% ``` Running some site benchmarks with Emoji support turned on: ```bash benchmark old ns/op new ns/op delta BenchmarkSiteBuilding/TOML,num_langs=3,num_pages=5000,tags_per_page=5,shortcodes,render-4 924556797 818115620 -11.51% benchmark old allocs new allocs delta BenchmarkSiteBuilding/TOML,num_langs=3,num_pages=5000,tags_per_page=5,shortcodes,render-4 4112613 4133787 +0.51% benchmark old bytes new bytes delta BenchmarkSiteBuilding/TOML,num_langs=3,num_pages=5000,tags_per_page=5,shortcodes,render-4 426982864 424363832 -0.61% ``` Fixes #5534
* parser/pageparser: Fix handling of commented out front matterBjørn Erik Pedersen2018-11-28
| | | | | | | | | | | | | | When the page parser was rewritten in 0.51, this was interpreted literally, but commented out front matter is used in the wild to "hide it from GitHub", e.g: ``` <!-- +++ title = "hello" +++ --> ``` Fixes #5478
