* alpm_list: abort on memory allocation failureAndrew Gregory2017-07-06
| | | | | | | | | | | | | 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>

* use sockets for scriptlet/hook communicationAndrew Gregory2017-04-16
| | | | | | | | | | | 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.

* unlink_file: strip trailing slashesAndrew Gregory2017-04-16
| | | | | | | | | | | | | | 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.

* libalpm: Use archive_read_extract2Armin K2017-04-12
| | | | | | | | | | | | | | archive_read_extract() forces resolution of uid/gid to names when extracting the tarball. This can lead to wrong file ownership when using pacman with -r option and when uid/gid differ in the host and in the chroot. archive_read_extract2() uses uid's and gid's only.

| | | | | | | | | | | | If a comment in an INSTALL file contains the name of a valid INSTALL file function but the function itself is not present, pacman tries to execute that function.

* conflict: skip dir children when replacing a fileAndrew Gregory2017-01-04
| | | | | | | | | | | | | When replacing a file with a directory, any files under that directory do not need to be checked for conflicts. This prevents possible false-positive conflicts where the file being replaced is a symlink. We were already skipping the directory children when the file was owned by the previous version of a package being upgraded. This extends that to other packages being removed.

* Parametrise the different ways in which the payload is resetMartin Kühne2016-12-05
| | | | | | | | | | | | | | | | | | | In FS#43434, Downloads which fail and are restarted on a different server will resume and may display a negative download speed. The payload's progress in libalpm was not properly reset which ultimately caused terminal noise because the line width calculation assumes positive download speeds. This patch fixes the incomplete reset of the payload by mimicing what be_sync.c:alpm_db_update() does over in sync.c:download_single_file(). The new dload.c:_alpm_dload_payload_reset_for_retry() extends beyond the current behavior by updating initial_size and prevprogress for this case. This makes pacman reset the progress properly in the next invocation of the callback and display positive download speeds. Fixes FS#43434.

* Represent bitfields as ints, not enumsIvy Foster2016-10-22
| | | | | | | | | | Many bitfield variables are declared to be enums, because they are generated using bitwise operations on enums such. However, their actual values aren't necessary members of their parent enum, so declaring them 'int' is more accurate.

* Add ALPM_ERR_OK to _alpm_errno_tIvy Foster2016-10-22
| | | | | | | | | | This allows functions which return an _alpm_errno_t to always return a genuine _alpm_errno_t for consistency, even in cases where there are no errors. Since ALPM_ERR_OK = 0, their callers can still simply check 'err = some_fn(); if (!err) { ... }'. Signed-off-by: Ivy Foster <ivy.foster@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* Allow replacing libcrypto with libnettle in pacmanFlorian Weigelt2016-10-22

* Remove SHA224 supportAllan McRae2016-10-10
| | | | | | | | This was included due to use of PolarSSL's implementation for our internal SHA2 support. As our internal checksum calculations are now removed, we can also remove this unused code path. Signed-off-by: Allan McRae <allan@archlinux.org>
* Remove internal md5 and sha2 implementationsAllan McRae2016-10-10
| | | | | | | | | | | | | | | The internal implementations for md5 and sha256 checksums have not been merged from upstream sources for a long time. Instead of us carrying copies of code from other projects, we should just support building against multiple libraries that provide such functionality. This patch removes the md5 and sha2 code (originally obtained from PolarSSL) from our repository. The configure script will now error unless at least one library supporting checksum generation is present, with the only library currently supported being openssl. It will be relatively simple for other such libraries (e.g. nettle) to be supported if anyone wishes to add them. Signed-off-by: Allan McRae <allan@archlinux.org>
