2016-08-30Normalize alpm download callback's frontend cb argumentsIvy Foster
When curl calls alpm's dlcb, alpm calls the frontend's cb with the following (dlsize, totalsize) arguments: 0, -1: initialize 0, 0: no change since last call x {x>0, x<y}, y {y>0}: data downloaded, total size known x {x>0}, x: download finished If total size is not known, do not call frontend cb (no change to original behavior); alpm's callback shouldn't be called if there is a download error. See agregory's original spec here: https://wiki.archlinux.org/index.php/User:Apg#download_callback Signed-off-by: Allan McRae <allan@archlinux.org>

2016-08-30hook.c: replace fstatat with statAndrew Gregory
macOS < 10.10 do not provide fstatat. We were constructing the full path to the hook file for all other operations anyway, so there was no real benefit to using fstatat. Fixes FS#49771 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2016-08-30Reject files larger than 16384 bytes in read_sigfile.Tobias Stoeckmann
If signature files are larger than SIZE_MAX, not enough memory could be allocated for this file. The script repo-add rejects files which are larger than 16384 bytes, therefore handle these as errors here, too. While at it, I also rearranged the code to avoid a quite harmless TOCTOU race condition between stat() and fopen().

2016-08-30Always use proper error code in alpm_initialize.Tobias Stoeckmann
In out of memory conditions, an undefined error value is written into *err, because myerr is never explicitly set in these cases. I have also converted a calloc into a MALLOC call, because the memory will be properly filled by the snprintf call right after it.

2016-08-30recursedeps: include cyclic dependenciesAndrew Gregory
Cyclic dependencies (A depends on B, B depends on A) were not selected because neither package could be removed individually, so can_remove_package would always return false for both. By preselecting all dependencies then filtering back out any dependencies still required by any packages that will not be uninstalled, groups of unneeded cyclic dependencies can be found.

2016-05-05Avoid logical OR duplication warning from gcc-6Allan McRae
The value EAGAIN is allowed by POSIX to be the same as EWOULDBLOCK, but this is not guaranteed. Thus on some systems (e.g. glibc Linux), we get a warning that the logical OR is being performed on two expressions of the same type. We can not get rid of this test in case any system defines these as unique values. Suggested-by: Dave Reisner Signed-off-by: Allan McRae <allan@archlinux.org>
2016-05-05Prevent wrapping of enum itemsAllan McRae
GCC-6 points out that the value we use for the sentinal in enums is actually too large for the integer type. Reduce the bitshift by one to fix this. Signed-off-by: Allan McRae <allan@archlinux.org>

2016-02-23make alpm_unlock and trans_interrupt async safeAndrew Gregory
RET_ERR calls _alpm_log which includes calls that are not safe for use in asynchronous signal handlers (see signal(7)). Replace it in functions called from our signal handlers with a new macro RET_ERR_ASYNC_SAFE which is identical except that it lacks the call to _alpm_log.

2016-02-23alpm_run_chroot: always connect parent2child pipeAndrew Gregory
Commit e374e6829cea3512f0b4a4069c5a6168f0f8d8a0 closed stdin before running scripts/hooks. This left the exec'd process with no file descriptor 0. If the process subsequently opened a file it would be assigned fd 0, and could potentially be confused for stdin. Connecting and immediately closing the parent2child pipe ensures that the child has an fd 0 and that it is empty.

2016-02-23ensure gpgdir has a trailing slashAndrew Gregory
init_gpgme checks for various paths under gpgdir by concatenating them directly, giving warning messages incorrectly if gpgdir does not end with '/'. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2016-02-23do not rely on localdb for hook matchingAndrew Gregory
Relying on localdb to determine which trigger operations should match is completely broken for PostTransaction hooks because the localdb has already been updated.

2016-01-15add alpm_list_appendAndrew Gregory
alpm_list_add always returns the provided list making it impossible for callers to check whether or not the operation actually succeeded without manually comparing the list length before and after. alpm_list_append instead returns a pointer to the newly created list item so that success can be checked.

2016-01-04Make alpm_graph state signedness explicitRikard Falkeborn
The signedness of char is implementation defined. Since the alpm_graph state is clearly meant to be signed, make the signedness explicit. This fixes bugs on systems where char is unsigned, in comparissons of the following type: if(v.state == -1) which, if state is unsigned, will never be true due to integer promotion rules. Fixes failing test/pacman/tests/sync012.py when compiling with -funsigned-char. Fixes two warnings [-Wtype-limits] for comparissons with -1 when compiling with -funsigned-char.

The CheckSpace option checks the size of all files in a package being replaced and gives a warning when it can not read the file. However, files in NoExtract are expected to be missing and should not be warned about. Fixes FS#47470. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-15alpm: Abort ASAP on failure in pre-transaction hooksOlivier Brunel
There is no need to run any/remaining pre-transaction hooks as soon as a failure has occured, which will lead to aborting the transaction. So if an error occured during the first phase (reading directories/parsing files), or as soon as a hook flagged abort_on_fail does fail, we stop processing them and return. (For post-transaction hooks, all hooks are run regardless since there's no aborting.) Signed-off-by: Olivier Brunel <jjk@jjacky.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-15alpm-hooks: add Description fieldAllan McRae

2015-12-06alpm_initialize: Fix double slash in sys hook dir pathDavid Macek
The path of the default system hook directory was created by concatenating `myhandle->root` (usually "/"), and SYSHOOKDIR (usually "/usr/share/libalpm/hooks/"), resulting in "//usr/share/libalpm/hooks/". Fix this by skipping the initial slash from SYSHOOKDIR. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-06db_update: always clear db flags after updateAndrew Gregory
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.

2015-12-05skip conflicts resolved by file replacementAndrew Gregory
When replacing a file with a directory, any files inside the new directory cannot possibly exist on the filesystem and can be skipped. This allows cross-package symlink-to-directory transitions when there are files with the same name under both the symlinked directory and the new directory.

2015-12-05always unlink files before extractionAndrew Gregory
libarchive will not extract a directory over an existing directory symlink, making it impossible to replace a symlink with a directory across packages. Adding the ARCHIVE_EXTRACT_UNLINK and ARCHIVE_EXTRACT_SECURE_SYMLINKS causes libarchive to unlink the existing symlink and prevents it from extracting any paths that contain a symlink, which we should not be doing anyway.

2015-12-04Add large file support CFLAGS to pkgconfig fileAllan McRae
Large file support is enabled by our configure script as required. If anything linking to libalpm does not also define large file support, there will be differences in the size of off_t which are not caught until runtime.
