[pacman-dev] [PATCH] Hide cursor while pacman is running
by Anatol Pomozov 05 Mar '20

05 Mar '20

Use ASCII control codes to hide cursor at the pacman start and then show the cursor when pacman finishes. It helps to avoid annoying blinking when progress bars are re-drawn. Cursor is reenabled if pacman expects user's input.

[pacman-dev] [PATCH] makepkg: Include more source files in debug packages.
by Austin Lund 01 Mar '20

01 Mar '20

Currently only the file pointed to by the DW_AT_name is included as a source file in debug packages. This means many files that are useful for debugging are not included. For example, no header files are included but yet these may by referenced in the .debug_line section. This sed script converts into shell variables the debug dump information from readelf about compilation units, directory tables and file tables. This can be used to get the full path of all the source files from within the package being compiled that are referenced in the debugging information. Also, placeholder symbols (e.g. <builtin>) and paths outside the current source (e.g. linked libraries) will be more consistently ignored from inclusion in the debug packages.
