2020-11-26Move cursor to the end of the screen at the SIGINTAnatol Pomozov3-13/+15
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.

2020-11-26Go to the end of screen if 'printonly' mode enabledAnatol Pomozov1-0/+1
At the end of download operation our code makes sure the cursor is moved to the end of the drawing area. But 'printonly' mode has its own if() branch that skips this cursor alignment. Add cursor_goto_end() to the 'printonly' codepath to make sure it does not clobber previous output.

For printf in C, width is counted as bytes rather than Unicode width. [1] > If the precision is specified, no more than that many bytes are written.

2020-06-26Convert '-U pkg1 pkg2' codepath to parallel downloadAnatol Pomozov1-54/+48
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>
2020-06-01Avoid depending on side effects in assert(...) expressionsDave Reisner1-2/+6
When building with -DNDEBUG, assert statements are compiled out to no-ops. Thus, we can't depend on assignments or other computations occurring inside the assert(). Signed-off-by: Allan McRae <allan@archlinux.org>

This removes support for autotools in favour of meson.
2020-05-11Log invalid conf settings as an errorEli Schwartz1-4/+4
This is not a warning, _parse_options() returns failure without even parsing further lines and the attempted pacman/pacman-conf program execution immediately aborts. Warnings are for when e.g. later on if we don't recognize a setting at all, we skip over it and have enough confidence in this to continue executing the program. The current implementation results in pacman-conf aborting with: warning: config file /etc/pacman.conf, line 60: invalid value for 'ParallelDownloads' : '2.5' error parsing '/etc/pacman.conf' or pacman -Syu aborting with the entirely more cryptic: warning: config file /etc/pacman.conf, line 59: invalid value for 'ParallelDownloads' : '2.5' and this isn't just a problem for the newly added ParallelDownloads setting, either, you could get the same problem if you specified a broken XferCommand, but that's harder as it's more accepting of input and you probably don't hit this except with unbalanced quotes.

2020-05-11pacman-conf: fix incomplete support for ILoveCandyEli Schwartz1-0/+2

2020-05-09Implement multibar UIAnatol Pomozov5-129/+286
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.

2020-05-09Extend download callback interface with start/complete eventsAnatol Pomozov3-3/+12
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 Pomozov1-3/+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.

2020-03-13Hide cursor while pacman is runningAnatol Pomozov4-5/+38

The documentation of the return types of alpm_mtree_next was incorrect. This extended into the relevant function in be_local.c.

2019-11-08pacman+libalpm: handle search errorsmorganamilo3-4/+23

system() runs the provided command via a shell, which is subject to command injection. Even though pacman already provides a mechanism to sign and verify the databases containing the urls, certain distributions have yet to get their act together and start signing databases, leaving them vulnerable to MITM attacks. Replacing the system call with an almost equivalent exec call removes the possibility of a shell-injection attack for those users. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>

2019-10-07signing: move key import confirmation before key_searchJonas Witschel1-11/+2
Ask the user whether they want to import a missing key before even doing a search on the keyserver. This will be useful for getting Web Key Directory support in place: for a WKD, looking up and importing a key are a single action, so the current key_search -> QUESTION -> key_import workflow does not apply. Since only the ID of the package signing key is available before key_search, we display the packager variable in addition to the key ID for user convenience.

Also distribute all src/common/ files. We never strictly needed any of them to be distributed with autotools, because the dist tarball dereferences the symlinks (???), but only some of them were being distributed, and meson needs them to be in the right location as we only build libcommon from the primary files.
