Introduce a tree map for all content This commit introduces a new data structure to store pages and their resources. This data structure is backed by radix trees. This simplies tree operations, makes all pages a bundle, and paves the way for #6310. It also solves a set of annoying issues (see list below). Not a motivation behind this, but this commit also makes Hugo in general a little bit faster and more memory effective (see benchmarks). Especially for partial rebuilds on content edits, but also when taxonomies is in use. ``` name old time/op new time/op delta SiteNew/Bundle_with_image/Edit-16 1.32ms ± 8% 1.00ms ± 9% -24.42% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file/Edit-16 1.28ms ± 0% 0.94ms ± 0% -26.26% (p=0.029 n=4+4) SiteNew/Tags_and_categories/Edit-16 33.9ms ± 2% 21.8ms ± 1% -35.67% (p=0.029 n=4+4) SiteNew/Canonify_URLs/Edit-16 40.6ms ± 1% 37.7ms ± 3% -7.20% (p=0.029 n=4+4) SiteNew/Deep_content_tree/Edit-16 56.7ms ± 0% 51.7ms ± 1% -8.82% (p=0.029 n=4+4) SiteNew/Many_HTML_templates/Edit-16 19.9ms ± 2% 18.3ms ± 3% -7.64% (p=0.029 n=4+4) SiteNew/Page_collections/Edit-16 37.9ms ± 4% 34.0ms ± 2% -10.28% (p=0.029 n=4+4) SiteNew/Bundle_with_image-16 10.7ms ± 0% 10.6ms ± 0% -1.15% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file-16 10.8ms ± 0% 10.7ms ± 0% -1.05% (p=0.029 n=4+4) SiteNew/Tags_and_categories-16 43.2ms ± 1% 39.6ms ± 1% -8.35% (p=0.029 n=4+4) SiteNew/Canonify_URLs-16 47.6ms ± 1% 47.3ms ± 0% ~ (p=0.057 n=4+4) SiteNew/Deep_content_tree-16 73.0ms ± 1% 74.2ms ± 1% ~ (p=0.114 n=4+4) SiteNew/Many_HTML_templates-16 37.9ms ± 0% 38.1ms ± 1% ~ (p=0.114 n=4+4) SiteNew/Page_collections-16 53.6ms ± 1% 54.7ms ± 1% +2.09% (p=0.029 n=4+4) name old alloc/op new alloc/op delta SiteNew/Bundle_with_image/Edit-16 486kB ± 0% 430kB ± 0% -11.47% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file/Edit-16 265kB ± 0% 209kB ± 0% -21.06% (p=0.029 n=4+4) SiteNew/Tags_and_categories/Edit-16 13.6MB ± 0% 8.8MB ± 0% -34.93% (p=0.029 n=4+4) SiteNew/Canonify_URLs/Edit-16 66.5MB ± 0% 63.9MB ± 0% -3.95% (p=0.029 n=4+4) SiteNew/Deep_content_tree/Edit-16 28.8MB ± 0% 25.8MB ± 0% -10.55% (p=0.029 n=4+4) SiteNew/Many_HTML_templates/Edit-16 6.16MB ± 0% 5.56MB ± 0% -9.86% (p=0.029 n=4+4) SiteNew/Page_collections/Edit-16 16.9MB ± 0% 16.0MB ± 0% -5.19% (p=0.029 n=4+4) SiteNew/Bundle_with_image-16 2.28MB ± 0% 2.29MB ± 0% +0.35% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file-16 2.07MB ± 0% 2.07MB ± 0% ~ (p=0.114 n=4+4) SiteNew/Tags_and_categories-16 14.3MB ± 0% 13.2MB ± 0% -7.30% (p=0.029 n=4+4) SiteNew/Canonify_URLs-16 69.1MB ± 0% 69.0MB ± 0% ~ (p=0.343 n=4+4) SiteNew/Deep_content_tree-16 31.3MB ± 0% 31.8MB ± 0% +1.49% (p=0.029 n=4+4) SiteNew/Many_HTML_templates-16 10.8MB ± 0% 10.9MB ± 0% +1.11% (p=0.029 n=4+4) SiteNew/Page_collections-16 21.4MB ± 0% 21.6MB ± 0% +1.15% (p=0.029 n=4+4) name old allocs/op new allocs/op delta SiteNew/Bundle_with_image/Edit-16 4.74k ± 0% 3.86k ± 0% -18.57% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file/Edit-16 4.73k ± 0% 3.85k ± 0% -18.58% (p=0.029 n=4+4) SiteNew/Tags_and_categories/Edit-16 301k ± 0% 198k ± 0% -34.14% (p=0.029 n=4+4) SiteNew/Canonify_URLs/Edit-16 389k ± 0% 373k ± 0% -4.07% (p=0.029 n=4+4) SiteNew/Deep_content_tree/Edit-16 338k ± 0% 262k ± 0% -22.63% (p=0.029 n=4+4) SiteNew/Many_HTML_templates/Edit-16 102k ± 0% 88k ± 0% -13.81% (p=0.029 n=4+4) SiteNew/Page_collections/Edit-16 176k ± 0% 152k ± 0% -13.32% (p=0.029 n=4+4) SiteNew/Bundle_with_image-16 26.8k ± 0% 26.8k ± 0% +0.05% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file-16 26.8k ± 0% 26.8k ± 0% +0.05% (p=0.029 n=4+4) SiteNew/Tags_and_categories-16 273k ± 0% 245k ± 0% -10.36% (p=0.029 n=4+4) SiteNew/Canonify_URLs-16 396k ± 0% 398k ± 0% +0.39% (p=0.029 n=4+4) SiteNew/Deep_content_tree-16 317k ± 0% 325k ± 0% +2.53% (p=0.029 n=4+4) SiteNew/Many_HTML_templates-16 146k ± 0% 147k ± 0% +0.98% (p=0.029 n=4+4) SiteNew/Page_collections-16 210k ± 0% 215k ± 0% +2.44% (p=0.029 n=4+4) ``` Fixes #6312 Fixes #6087 Fixes #6738 Fixes #6412 Fixes #6743 Fixes #6875 Fixes #6034 Fixes #6902 Fixes #6173 Fixes #6590
