[pacman-dev] [PATCH v3] libalpm: fix download rates becoming negative
by morganamilo 09 May '21

09 May '21

When a download fails on one mirror a new download is started on the next mirror. This causes the ammount downloaded to reset, confusing the rate math and making it display a negative rate. This is further complicated by the fact that a download may be resumed from where it is or started over. To account for this we alert the frontend that the download was restarted. Pacman then starts the progress bar over. --- v2: stat tempfile to get initial_size v3: review fixes --- lib/libalpm/alpm.h | 7 +++++++ lib/libalpm/dload.c | 33 +++++++++++++++++++++++++-------- src/pacman/callback.c | 30 ++++++++++++++++++++++++++++++ 3 files changed, 62 insertions(+), 8 deletions(-) diff --git a/lib/libalpm/alpm.h b/lib/libalpm/alpm.h index 101d686b..226fd953 100644 --- a/lib/libalpm/alpm.h +++ b/lib/libalpm/alpm.h @@ -1172,6 +1172,8 @@ typedef enum _alpm_download_event_type_t { ALPM_DOWNLOAD_INIT, /** A download made progress */ ALPM_DOWNLOAD_PROGRESS, + /** Download will be retried */ + ALPM_DOWNLOAD_RETRY, /** A download completed */ ALPM_DOWNLOAD_COMPLETED } alpm_download_event_type_t;

When a download fails on one mirror a new download is started on the next mirror. This new download will have the initial size of whatever has been downloaded so far, as well as the ammount downloaded reset to 0.

Hello, eveyone! I'am a newbie, because of the experience of using pacman downloading with the `Ctrl +\` exit was not very good,it leave the database lock, so I am thinking can we just deal with SIGQUIT rather than doing nothing. Hopefully this will improve the experience of users. Thanks. ZheNing Hu (1): signhandler: add SIGQUIT soft_interrupt_handler src/pacman/sighandler.c | 3 +++ 1 file changed, 3 insertions(+) -- 2.31.0
