2016-02-23make alpm_unlock and trans_interrupt async safeAndrew Gregory1-3/+5
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.

This is necessary in order to be able to run PreTransaction hooks as close to the actual commit as possible so that we don't prematurely run hooks for a transaction that ultimately never happens.

2015-02-01trans_commit: restore pm_errno after updating logAndrew Gregory1-0/+4
If the call to alpm_logaction failed it would overwrite pm_errno, leading to error messages unrelated to the actual reason the transaction failed. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2014-10-13sync.c: download packages before starting commitAndrew Gregory1-0/+10
download_files sets the transaction state to STATE_DOWNLOADING. Modifying the state after it has already been set to STATE_COMMITTING created a brief window where SIGINT would fail to interrupt the process and caused interrupted downloads to result in a 'transaction started' message in the log with no matching transaction end. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2014-09-23wrap fgets to retry on EINTRAndrew Gregory1-1/+1
The read() underlying fgets() can be interrupted by a signal handler causing fgets() to return NULL. Before we started handling SIGWINCH, the odds of interrupting a read were low and typically resulted in termination anyway. Replace all fgets calls with a wrapper that retries in EINTR.

2014-01-28Remove ts and sw from vim modeline when noet is setFlorian Pritz1-1/+1
Forcing vim users to view files with a tabstop of 2 seems really unnecessary when noet is set. I find it much easier to read code with ts=4 and I dislike having to override the modeline by hand.

This fixes a bunch of small issues in order to enable a clean successful build with a crazy number of GCC warning flags. A lot of these changes are covered by -Wshadow, -Wformat-security, and -Wstrict-overflow=5. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-04-07Make selecting scriptlet shell workAllan McRae1-1/+1
The initial patch to implement this achieved nothing apart from adding a configure option. This patch makes that configure option do what it advertises. Note that specifing any shell apart from /bin/sh causes testsuite failures as /bin/sh is the only shell in the testing environment.

2012-02-13Allow specifying shell for running scriptletsAllan McRae1-1/+1
Some distributions insist on using bash specific commands in their install scripts under the assumption that "sh" is a symlink to bash. This can causes issues if (e.g.) their users what to change sh to point at another shell, such as dash, that does not support these features. Add a configure option to explicitly set the shell being used to run install scripts. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-22include config.h via MakefilesDave Reisner1-2/+0
Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.

2011-09-30Refactor _alpm_runscriptlet()Dan McGee1-18/+35
Add an is_archive parameter to reduce the amount of black magic going on. Rework to use fewer PATH_MAX sized local variables, and simplify some of the logic where appropriate in both this function and in the callers where duplicate calls can be replaced by some conditional parameter code. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-28Track unresolvable transaction packagesDan McGee1-0/+3
Rather than free them right away, keep the list on the transaction as we already do with add and remove lists. This is necessary because we may be manipulating pointers the frontend needs to refer to packages, and we are breaking our contract as stated in the alpm_add_pkg() documentation of only freeing packages at the end of a transaction. This fixes an issue found when refactoring the package list display code. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-20_alpm_runscriptlet(): remove clean_tmpdir variableDan McGee1-7/+4
This is always true at the end since we return early if we couldn't create the tmpdir, so it is totally unnecessary. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-19Be smarter about running ldconfig during removal transactionsDan McGee1-1/+1
1. Don't run it if something failed in package removal- this mirrors what we already do in sync transactions. 2. Don't run it if we are invoking it for the replaces removal bit of a sync transaction- it doesn't make sense to run ldconfig halfway through a sync install; we should only run it once at the end. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-03Move all callbacks up to the handle levelDan McGee1-6/+1
This was just disgusting before, unnecessary to limit these to only usage in a transaction. Still a lot of more room for cleanup but we'll start by attaching them to the handle rather than the transaction we may or may not even want to use these callbacks.

2011-08-18Remove use of no-op accessor functions in libraryDan McGee1-2/+2
The functions alpm_db_get_name(), alpm_pkg_get_name(), and alpm_pkg_get_version() are not necessary at all, so remove the calling and indirection when used in the backend, which makes things slightly more efficient and reduces code size. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-07-05Allow invalid sync DBs to be returned by the libraryDan McGee1-8/+0
They are placeholders, but important for things like trying to re-sync a database missing a signature. By using the alpm_db_validity() method at the right time, a client can take the appropriate action with these invalid databases as necessary. In pacman's case, we disallow just about anything that involves looking at a sync database outside of an '-Sy' operation (although we do check the validity immediately after). A few operations are still permitted- '-Q' ops that don't touch sync databases as well as '-R'. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-24Move locking functions to handleDan McGee1-50/+2
These operate on the handle, and the state is stored on the handle, so move them where they belong. Up until now only the transaction stuff calls them, but this will soon change and alpm_db_update() will handle locking all on its own. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-24Add a 'valid' flag to the database objectDan McGee1-0/+8
Start by converting all of our flags to a 'status' bitmask (pkgcache status, grpcache status). Add a new 'valid' flag as well. This will let us keep track if the database itself has been marked valid in whatever fashion. For local databases at the moment we ensure there are no depends files; for sync databases we ensure the PGP signature is valid if required/requested. The loading of the pkgcache is prohibited if the database is invalid. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-24Move database 'version' check to registration timeDan McGee1-12/+0
This is another step toward doing both local database validation (ensuring we don't have depends files) and sync database validation (via signatures if present) when the database is registered. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee1-8/+8
We didn't do due diligence before and ensure prior pm_errno values weren't influencing what happened in further ALPM calls. I observed one case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that flag persisting the entire time we were calling library code. Add a new CHECK_HANDLE() macro that does two things: 1) ensures the handle variable passed to it is non-NULL and 2) clears any existing pm_errno flag set on the handle. This macro can replace many places we used the ASSERT(handle != NULL, ...) pattern before. Several other other places only need a simple 'set to zero' of the pm_errno field.
