2020-11-26Move cursor to the end of the screen at the SIGINTAnatol Pomozov
It requires exposing 'move cursor to the end' function in a pacman header file. We use it as a chance to make naming of the cursor management functions more consistent. Note that there is still possibility of a race condition in the cursor update logic. 'update cursor index variable' and 'send ASCII control symbols to console' is not an atomic operation. So if an SIGINT is received between these two action then cursor position is going to be screwed. Fixes FS#67973 Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2020-03-13Hide cursor while pacman is runningAnatol Pomozov
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. Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2019-08-05create coredump on segfaultAndrew Gregory
Overriding the segfault handler prevents the creation of core dumps by the default handler, which makes debugging segfaults difficult. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2019-08-05sighandler: block signals while handling SIGSEGVAndrew Gregory
If we get SIGSEGV we need to bail out quickly, leaving other signals unblocked could lead to other signal handlers getting triggered. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2018-05-14Remove all modelines from the projectEli Schwartz
Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default). The only useful modelines are the ones enforcing the project coding standards for indentation style (and "maybe" filetype/syntax, but everything except the asciidoc manpages and makepkg.conf is already autodetected), and indent style can be applied more easily with .editorconfig Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-12-05remove soft interrupt handler before cleanupAndrew Gregory
The soft interrupt handler dereferences config, causing a segfault if it is called during cleanup. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

Delays handler setup until after config is set to a valid value to avoid a segmentation fault. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-12-05move signal handlers to sighandler.[ch]Andrew Gregory
Signals are special because they run asynchronously, making them non-trivial to handle correctly. Move the handlers a separate file to offset them from the normal code and make them easier to separate into individual functions without further cluttering pacman.c Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
