2021-01-19do not try to download an empty db listAndrew Gregory1-0/+4
Starting the download process, even if there is nothing to actually download, causes an error when pacman is built without curl and has no XferCommand defined (like our test suite). Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2021-01-08libalpm: introduce get_sync_pkg_ops() helperEmil Velikov1-2/+17
Currently default_pkg_ops is accessed in two different ways. There is get_file_pkg_ops (in be_package.c) creating a local once-off 'tweaked' copy. As well as load_pkg_for_entry (be_sync.c) which modifies in-place and uses default_pkg_ops. This seems rather misleading and fragile approach. Introduce a helper for the second use-case so that default_pkg_ops is handled consistently and essentially remains unchanged throughout.

2020-07-07Move signature payload creation to download engineAnatol Pomozov1-28/+6
Until now callee of ALPM download functionality has been in charge of payload creation both for the main file (e.g. *.pkg) and for the accompanied *.sig file. One advantage of such solution is that all payloads are independent and can be fetched in parallel thus exploiting the maximum level of download parallelism. To build *.sig file url we've been using a simple string concatenation: $requested_url + ".sig". Unfortunately there are cases when it does not work. For example an archlinux.org "Download From Mirror" link looks like this https://www.archlinux.org/packages/core/x86_64/bash/download/ and it gets redirected to some mirror. But if we append ".sig" to the end of the link url and try to download it then archlinux.org returns 404 error. To overcome this issue we need to follow redirects for the main payload first, find the final url and only then append '.sig' suffix. This implies 2 things: - the signature payload initialization need to be moved to dload.c as it is the place where we have access to the resolved url - *.sig is downloaded serially with the main payload and this reduces level of parallelism Move *.sig payload creation to dload.c. Once the main payload is fetched successfully we check if the callee asked to download the accompanied signature. If yes - create a new payload and add it to mcurl. *.sig payload does not use server list of the main payload and thus does not support mirror failover. *.sig file comes from the same server as the main payload. Refactor event loop in curl_multi_download_internal() a bit. Instead of relying on curl_multi_check_finished_download() to return number of new payloads we simply rerun the loop iteration one more time to check if there are any active downloads left.

2020-06-26Cleanup the old sequential download codeAnatol Pomozov1-1/+1
All users of _alpm_download() have been refactored to the new API. It is time to remove the old _alpm_download() functionality now. This change also removes obsolete SIGPIPE signal handler functionality (this is a leftover from libfetch days). Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com>
2020-05-09Swap alpm_db_update() implementation to multiplexed versionAnatol Pomozov1-166/+1
Now when all callers of the old alpm_db_update() function are gone we can remove this implementation. And then rename alpm_dbs_update() function to alpm_db_update(). Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2020-05-09Implement multibar UIAnatol Pomozov1-0/+1
Multiplexed download requires ability to draw UI for multiple active progress bars. To implement it we use ANSI codes to move cursor up/down and then redraw the required progress bar. `pacman_multibar_ui.active_downloads` field represents the list of active downloads that correspond to progress bars. `struct pacman_progress_bar` is a data structure for a progress bar. In some cases (e.g. database downloads) we want to keep progress bars in order. In some other cases (package downloads) we want to move completed items to the top of the screen. Function `multibar_move_completed_up` allows to configure such behavior. Per discussion in the maillist we do not want to show download progress for signature files.

2020-05-09Introduce event types for start/end database list downloadAnatol Pomozov1-0/+7
Multiplexed database/files downloads will use multiple progress bars. The UI logic is quite complicated and printing error messages while handling multiple progress bars is going to be challenging. Instead we are going to save all ALPM error messages to a list and flush it at the end of the download process. Use on_progress variable that blocks error messages printing.

2020-05-09Introduce alpm_dbs_update() function for parallel db updatesAnatol Pomozov1-0/+132
This is an equivalent of alpm_db_update but for multiplexed (parallel) download. The difference is that this function accepts list of databases to update. And then ALPM internals download it in parallel if possible. Add a stub for _alpm_multi_download the function that will do parallel payloads downloads in the future. Introduce dload_payload->filepath field that contains url path to the file we download. It is like fileurl field but does not contain protocol/server part. The rationale for having this field is that with the curl multidownload the server retry logic is going to move to a curl callback. And the callback needs to be able to reconstruct the 'next' fileurl. One will be able to do it by getting the next server url from 'servers' list and then concat with filepath. Once the 'parallel download' refactoring is over 'fileurl' field will go away. Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2020-04-13Add REALLOC macro to simplify realloc error handlingRikard Falkeborn1-1/+1
realloc can fail just like the other memory allocation functions. Add a macro to simplify handling of realloc failures, similar to the already existing MALLOC, CALLOC, etc. Replace the existing realloc uses with the new macro, allowing us to move tedious error handling to the macro. Also, in be_package and be_sync, this fixes hypothetical memory leaks (and thereafter null pointer dereferences) in case realloc fails to shrink the allocated memory.

Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default).

2015-12-05db_update: always clear db flags after updateAndrew Gregory1-22/+23
Signature downloading and DB validation was being based on the most recent download status for the DB. If a DB successfully downloaded but a signature did not, db_update would move to the next server. If the next server tried does not have a more recent copy of the DB, db_update would not download the DB again and would forget that the DB had previously been updated. In this case it would skip validation entirely, leaving an updated DB with the original validation status.

2015-08-08libalpm: Force update when database is marked as corrupted.Sebastian Lackner1-0/+5
When a database and its signature is updated non-atomically on a server, there is a window where a user may update the database but grab the old signature. The database is marked as invalid by libalpm, which can be fixed by forcing a refresh (assuming the server has caught up and the user realizes what has happened) or with a future update of the repo. Work around this by forcing a repository refresh whenever a database is invalid. Signed-off-by: Sebastian Lackner <sebastian@fds-team.de> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-07-15Read file lists from databasesAllan McRae1-2/+36
If a sync database contains a "files" file, the file list will be read.
