Normally, the temporary URL is only used once to generate thumbnails ad-hoc. However, when cache is enabled, a reference to the asset may be used in a cached version of a formatted body text, skipping the normal thumbnail generation routine. When an asset is replaced, currently, all thumbnails are removed and references to them are removed from the database. In case the asset is still referenced in a cached formatted body text, this could lead to an error when requesting the thumbnail, as the thumbnail request is no longer present in the system. As we do not know what posts use particular assets at this point in the code, it is best to work around this issue by unsetting the thumbnail filenames rather than deleting the entries outright. This effectively generates them again on the next request. In the future, we should aim to keep track of what posts make use of assets, so cache may be invalidated in a more targeted way. --- models/Image.php | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/models/Image.php b/models/Image.php index 99a9fbe..212c1dc 100644 --- a/models/Image.php +++ b/models/Image.php @@ -158,7 +158,8 @@ class Image extends Asset } return Registry::get('db')->query(' - DELETE FROM assets_thumbs + UPDATE assets_thumbs + SET filename = NULL WHERE id_asset = {int:id_asset}', ['id_asset' => $this->id_asset]); } From d8858c78bb9c37b789a14a558e04c952b9c48831 Mon Sep 17 00:00:00 2001 From: Aaron van Geffen Date: Thu, 7 Jul 2022 14:54:00 +0200 Subject: [PATCH 09/13] Thumbnails: crop from original size if 2x is unavailable --- models/Image.php | 2 ++ 1 file changed, 2 insertions(+) diff --git a/models/Image.php b/models/Image.php index 212c1dc..73fa459 100644 --- a/models/Image.php +++ b/models/Image.php @@ -79,6 +79,8 @@ class Image extends Asset if ((!isset($width) || $this->image_width >= $width * 2) && (!isset($height) || $this->image_height >= $height * 2)) $image_urls[2] = $this->getThumbnailUrl($width * 2, $height * 2, false); + else + $image_urls[2] = $this->getThumbnailUrl($this->image_width, $this->image_height, true); } else $image_urls[1] = $this->getUrl(); From b3808144caf282190240f84027bcbab766cced23 Mon Sep 17 00:00:00 2001 From: Aaron van Geffen Date: Fri, 8 Jul 2022 23:52:03 +0200 Subject: [PATCH 10/13] Address deprecation notices for certain function signatures --- models/Database.php | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/models/Database.php b/models/Database.php index aaa0dfc..8507fa7 100644 --- a/models/Database.php +++ b/models/Database.php @@ -488,7 +488,7 @@ class Database /** * This function can be used to insert data into the database in a secure way. */ - public function insert($method = 'replace', $table, $columns, $data) + public function insert($method, $table, $columns, $data) { // With nothing to insert, simply return. if (empty($data)) From 6369187eb7c3a3e6b91a2ca6ad03a6f419d00018 Mon Sep 17 00:00:00 2001 From: Aaron van Geffen Date: Fri, 8 Jul 2022 23:53:28 +0200 Subject: [PATCH 11/13] Add double-density thumbnails to albums and photo pages --- templates/PhotoPage.php | 6 ++---- templates/PhotosIndex.php | 10 ++++++++-- 2 files changed, 10 insertions(+), 6 deletions(-) diff --git a/templates/PhotoPage.php b/templates/PhotoPage.php index 2fdfbaf..800c521 100644 --- a/templates/PhotoPage.php +++ b/templates/PhotoPage.php @@ -65,11 +65,9 @@ class PhotoPage extends SubTemplate '; if ($this->photo->isPortrait()) - echo ' - '; + echo $this->photo->getInlineImage(null, 960); else - echo ' - '; + echo $this->photo->getInlineImage(1280, null); echo ' diff --git a/templates/PhotosIndex.php b/templates/PhotosIndex.php index 2d91129..1e8c793 100644 --- a/templates/PhotosIndex.php +++ b/templates/PhotosIndex.php @@ -90,8 +90,14 @@ class PhotosIndex extends SubTemplate Edit'; echo ' - - '; + + width() >= $width * 2 && $image->height() >= $height * 2) + echo ' srcset="', $image->getThumbnailUrl($width * 2, $height * 2, $crop, $fit), ' 2x"'; + + echo ' alt="" title="', $image->getTitle(), '">'; if ($this->show_labels) echo ' From c763967463d70d8de5cc7b51e110f2683780ca7d Mon Sep 17 00:00:00 2001 From: Aaron van Geffen Date: Thu, 14 Jul 2022 16:45:17 +0200 Subject: [PATCH 12/13] Prevent current page from being 0 if no items are present --- models/GenericTable.php | 2 +- models/PageIndex.php | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/models/GenericTable.php b/models/GenericTable.php index df54bda..0da224c 100644 --- a/models/GenericTable.php +++ b/models/GenericTable.php @@ -43,7 +43,7 @@ class GenericTable $this->start = empty($options['start']) || !is_numeric($options['start']) || $options['start'] < 0 || $options['start'] > $this->recordCount ?
