Xavier Del Campo Romero	2f1caebaae	README.md: Update according to thumbnail generation	2024-03-01 00:12:38 +01:00
Xavier Del Campo Romero	77327e7c2d	Display thumbnails, if available	2024-03-01 00:12:38 +01:00
Xavier Del Campo Romero	16ffb6848f	Add thumbnail generation tool This new application runs separately from slcl and communicates with it via a named pipe. When files are added/removed to/from the user directory, slcl shall write to the named pipe. Then, this new tool shall process incoming entries and generate or remove thumbnails accordingly. Such thumbnails are stored into a new directory inside the database directory, namely thumbnails/, which replicates the same structure as user/.	2024-03-01 00:12:38 +01:00
Xavier Del Campo Romero	917c689fd4	main.c: Add -m command line option to open a named pipe This write-only named pipe is meant to inform other processes about files that have been added/removed to/from the user/ directory. The syntax is line-oriented and is described below. For added files: +<space ...><path><LF> For removed files: -<space ...><path><LF> Paths shall always be absolute. Examples: + /home/test/db/user/alice/a picture.jpg - /home/test/db/user/bob/essay.txt As reported above, this feature has been made completely optional so as not to introduce breaking changes. A new command line option, namely -m, is required to enable this feature.	2024-03-01 00:12:38 +01:00
Xavier Del Campo Romero	a4c0a7f0e2	auth.c: Make use of crealpath crealpath already provides a mechanism to determine the current working directory from getcwd(3).	2024-03-01 00:12:37 +01:00
Xavier Del Campo Romero	523bc444ca	Introduce crealpath crealpath (for "custom realpath") is a custom implementation of realpath(3) that aims to work similarly to GNU's realpath(1). This implementation is provided due to the following reasons: - Future commits will require extracting an absolute path from a relative path, and/or process relative components from a path, such as ".." or ".". - realpath(3) is defined by POSIX.1-2008 as a XSI extension, and extensions are generally avoided in this repository whenever possible. - Additionally, realpath(3) requires the file or directory pointed to by the path to exist, which might not always be the case for slcl. - auth.c uses its own implementation to extract a dynamically allocated string by repeatedly calling getcwd(3). Future commits will also require this future, so it makes sense to keep it on a separate component.	2024-03-01 00:12:37 +01:00
Xavier Del Campo Romero	b4572c6217	page.c: Do not get filename on previews This change should provide the same behaviour, but would avoid unnecessary calls to dynstr_append and basename(3) when a preview is to be served.	2024-03-01 00:06:03 +01:00
Xavier Del Campo Romero	fb8896bccd	README.md: Update dependencies list - jq is required by usergen. - Despite being part of a POSIX.1-2008 environment, m4 is not provided by Debian or Ubuntu by default.	2024-02-24 08:39:25 +01:00
Xavier Del Campo Romero	dd29f9096a	usergen: Do not abort on existing directory Otherwise, it would not be possible to replace user credentials if the directory already exists.	2024-02-20 21:44:53 +01:00
