2021-05-09libalpm: fix download rates becoming negativemorganamilo1-0/+7
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. Signed-off-by: Allan McRae <allan@archlinux.org>
2021-05-09libalpm: clone data on alpm_db_set_serversmorganamilo1-4/+3
Every alpm_option_set function clones the input so lets be more consistent. Also this fixes servers not being sanatized. Signed-off-by: Allan McRae <allan@archlinux.org>
2021-05-01alpm_db_update: indicate if dbs were up to dateAndrew Gregory1-1/+2
Restore the prior indicator whether or not databases were up to date. 0 is used to indicate if *any* db was actually updated as callers are more likely to care about that than if *all* dbs were updated. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2021-05-01add front-end provided context to callbacksAndrew Gregory1-13/+60
Our callbacks require front-ends to maintain state in order to provide reasonable output. The new download callback in particular requires much more complex state information to be saved. Without the ability to provide context, state must be saved globally, which may not be possible for all front-ends. Scripting language bindings in particular have no way to register per-handle callbacks without some form of context. Implements: FS#12721 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2021-04-21Add support for multiple 'Architecture' valuesDan McGee1-9/+21
This allows architecture to be multivalued. On x86-64 machines, this could be something like: Architecture = x86-64-v3 x86-64 We use the first specified Architecture value in mirrorlist $arch variable replacement, as this is backwards-compatible and sane.

2021-03-25Remove "total download" callback in favor of generic event callbackAnatol Pomozov1-20/+12
Total download callback called right before packages start downloaded. But we already have an event for such event (ALPM_EVENT_PKG_RETRIEVE_START) and it is naturally to use the event to pass information about expected download size.

2020-07-07Fallback to detached signatures during keyring checkAnatol Pomozov1-0/+11
Pacman has a 'key in keyring' verification step that makes sure the signatures have a valid keyid. Currently pacman parses embedded package signatures only. Add a fallback to detached signatures. If embedded signature is missing then it tries to read corresponding *.sig file and get keyid from there. Verification: debug: found cached pkg: /var/cache/pacman/pkg/glib-networking-2.64.3-1-x86_64.pkg.tar.zst debug: found detached signature /var/cache/pacman/pkg/glib-networking-2.64.3-1-x86_64.pkg.tar.zst.sig with size 310 debug: found signature key: A5E9288C4FA415FA debug: looking up key A5E9288C4FA415FA locally debug: key lookup success, key exists Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2020-06-26Convert '-U pkg1 pkg2' codepath to parallel downloadAnatol Pomozov1-5/+10
Installing remote packages using its URL is an interesting case for ALPM API. Unlike package sync ('pacman -S pkg1 pkg2') '-U' does not deal with server mirror list. Thus _alpm_multi_download() should be able to handle file download for payloads that either have 'fileurl' field or pair of fields ('servers' and 'filepath') set. Signature for alpm_fetch_pkgurl() has changed and it accepts an output list that is populated with filepaths to fetched packages. Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com>
2020-05-09Swap alpm_db_update() implementation to multiplexed versionAnatol Pomozov1-38/+2
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>

2020-05-09Extend download callback interface with start/complete eventsAnatol Pomozov1-3/+32
With the previous download interface the callback uses the first progress event as 'download has started' signal. Unfortunately it does not work with up-to-date files that never receive 'download progress' events. Up-to-date database messages are currently handled in sync_syncdbs() after the sequential download is completed and a result from ALPM is received. But this is not going to work with multiplexed download interface that returns the result only after all files are completed. Another problem with 'first progress event is the beginning of the download' is that such events time are unpredictable. Thus the UI progress bar order might differ from what has been passed by client to alpm_dbs_update() function. We actually want to keep the dbs progress bars in a strict order. To help to solve the given problems extend the download callback to allow 2 more events - download started and completed. 'Download started' events appear in the same order as in the list given by a client. Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2020-05-09Introduce event types for start/end database list downloadAnatol Pomozov1-6/+12
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/+29
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>
2020-05-09Add config option to specify amount of parallel download streamsAnatol Pomozov1-0/+9

The documentation of the return types of alpm_mtree_next was incorrect. This extended into the relevant function in be_local.c. Also, return explicit integer values, rather than the ARCHIVE_xxx values, to avoid unnecessarily exposing frontends to libarchive internals (even though it makes no functional difference).

2019-01-10libalpm/sync.c: change alpm_sync_newversion() to alpm_sync_get_new_version()Allan McRae1-1/+1
The behaviour of "pacman -Qu" was very strange... It would only consider packages from repos with Usage = Search (or All), and ignore those with Usage = Sync, Install or Upgrade. This is because the function alpm_sync_newversion() used ALPM_DB_USAGE_SEARCH for its filtering. Given this function is documented (at least in the source) to "Check for new version of pkg in sync repos", I would expect that to look at all repos. However, just changing this parameter, would result in a fairly silent change in behaviour of this function. Instead, rename the function and remove this filtering altogether. Users of this function can filter the dbs passed to this function to achieve their desired output. Signed-off-by: Allan McRae <allan@archlinux.org>
