2018-10-21handle EINTR while polling scripts/hooksAndrew Gregory
If poll() is interrupted by a signal, alpm was closing the socket it uses for listening to script/hook output. This would drop script output at the least and kill the script at the worst. Fixes FS#60396 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2018-10-21reset signal handlers before running scripts/hooksAndrew Gregory
Front-ends or libraries may set signals to be ignored, which gets inherited across fork and exec. This can cause scripts to malfunction if they expect the signal. To make matters worse, scripts written in bash can't reset signals that were ignored when bash was started.

2018-10-17alpm: Fix SIGINT handling re: aborting downloadOlivier Brunel
Upon receiving SIGINT a flag is set to abort the (curl) download. However, since it was never reset/initialized, if a front-end doesn't actually exit on SIGINT, and later tries any operation that needs to perform a new download, said download would always get aborted right away due to the flag not having been reset.
2018-10-17alpm: Do not raise SIGINT when filesize goes over limitOlivier Brunel
Variable dload_interrupted is used both to abort a download because SIGINT was caught, and when a file limit is reached. But raising SIGINT is only meant to happen in the first case. Signed-off-by: Olivier Brunel <jjk@jjacky.com>
2018-09-19User-visible log when validity check fails due to accessDavid Phillips
Currently, if checking the validity of packages fails due to an access error on one or more packages, the user must sift through debug output in order to find the culprit package(s). This patch adds a call to _alpm_log in such a case to make the culprits more easily visible. Signed-off-by: Allan McRae <allan@archlinux.org>

2018-07-27Handle root prefix in overwrite operationsAllan McRae
The pacman --overwrite operation currently expects a path without the root prefix specified. This is unexpected, particularly given our conflict error message reports the path with the root prefix included. This patch allows libalpm to overwrite files with the root prefix specified.

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>
2018-05-12Fix gcc8 warnings.Eli Schwartz
Attempting to compile pacman with gcc8 results in several warnings like: remove.c: In function ‘unlink_file.isra.4’: remove.c:407:34: warning: ‘.pacsave.’ directive output may be truncated writing 9 bytes into a region of size between 1 and 4096 [-Wformat-truncation=] Fix by adding checks to error out if snprintf tries to reserve a truncated filename. Because the return values are checked, gcc delegates the truncation response to our code instead of throwing warnings.

2018-01-11Support new OpenPGP format packets lengthsAllan McRae
RFC 4880 defines two packet formats for OpenPGP. Pacman aborted its key in keyring check with an error message if it encountered the new format. This was fine until some annoying Arch Trusted User generated a key using the new format! Implement the new format. This also required parsing the hashed sub packets. requiring the parsing code to moved to its own function. Signed-off-by: Allan McRae <allan@archlinux.org>

2018-01-10Do not continuously try to open an invalid databaseAllan McRae
If you manage to download a bad database (e.g. an html file when behind a proxy or with a badly configured webserver), pacman makes sure you know about it. Here is some example output: error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format I don't know how many times that gets printed because it goes beyond my scrollback buffer.

2018-01-06do not rely on name hashes for matchingAndrew Gregory
6cfc4757b98e813428d261dbc185e20618ca83a6 was overzealous in attempting to optimize away a call to strcmp based on a comparison of hashes. The call can be skipped if the hashes are different, but different strings could have the same hash.

2018-01-06dload: ensure callback is always initialized onceAndrew Gregory
Frontends rely on an initialization call for setup between downloads. Checking for intialization after checking for a completed download can skip initialization in cases where files are small enough to be downloaded all at once (FS#56408). Relying on previous download size can result in multiple initializations if there are multiple non-transfer events prior to the download starting (fS#56468). Introduce a new cb_initialized variable to the payload struct and use it to ensure that the callback is initialized exactly once prior to any actual events.

This is a rewrite of Tobias Stoeckmann’s patch from June 2016[1] using functions instead of macros. (Thanks to Tobias for explanations of his patch.) A short question on Freenode IRC showed that macros are generally discouraged and functions should be used. The patch introduces a static size_t length_check() in libalpm/signing.c.

2017-07-06alpm_list: abort on memory allocation failureAndrew Gregory
This makes it possible to detect a failure in several alpm_list functions. Previously these functions would continue after a failure, returning partial results and potentially leaking memory. Unfortunately, NULL is a valid return value for the affected functions if the input list is empty, so they still do not have a dedicated error value. Callers can at least detect an error by checking if the input list was empty. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2017-04-16use sockets for scriptlet/hook communicationAndrew Gregory
If a scriptlet/hook dies at the wrong moment it can trigger SIGPIPE, terminating the process. For pipes, there is no way to prevent SIGPIPE other than ignoring it process-wide. This can have unintended consequences in a multi-threaded process. Using send(2) with sockets, however, allows ignoring SIGPIPE on a per-call basis, leaving other threads able to make use of SIGPIPE.

If the user replaces a directory with a symlink, libalpm would get confused because the trailing slash causes system calls to resolve the symlink. This leads to errors and a misleading message during upgrades. Even though libalpm does not support this, it should not be giving misleading errors. Also adds an overflow check.
