* dload: dont forget to initialize open_modeXavier Chantry2011-04-02
| | | | | | | | | | | That's a funny one, building with optimization levels (with both gcc and clang) caused open_mode to always be set to "ab", which worked. This was spotted both with clang-analyzer, and by Jakob who reported a segfault as he was using an un-optimized build.

* lib/dload: code simplificationDave Reisner2011-03-27
| | | | | | | | | Based on the fact that localf always points to the same file, there's no need to code in multiple fopen calls with varying results. Instead, track the desired file open mode and make a single call to fopen. Signed-off-by: Dave Reisner <d@falconindy.com> Signed-off-by: Dan McGee <dan@archlinux.org>

* Style change: return(x) --> return xDan McGee2011-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was discussed and more or less agreed upon on the mailing list. A huge checkin, but if we just do it and let people adjust the pain will end soon enough. Rebasing should be relatively straighforward for anyone that sees conflicts; just be sure you use the new return style if possible. The following semantic patch was used to do the change, along with some hand-massaging in order to preserve parenthesis where appropriate: The semantic match that finds this problem is as follows, although some hand-massaging was done in order to keep parenthesis where appropriate: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a; @@ - return(a); + return a; // </smpl> A macros_file was also provided with the following content: Additional steps taken, mainly for ASSERT() macros: $ sed -i -e 's#return(NULL)#return NULL#' lib/libalpm/*.c $ sed -i -e 's#return(-1)#return -1#' lib/libalpm/*.c Signed-off-by: Dan McGee <dan@archlinux.org>

* Use limits.h for PATH_MAXAllan McRae2010-12-29
| | | | | | | | | | | | We use PATH_MAX everywhere by including limits.h so there is no point in doing a check for it in a different header when dealing with FreeBSD's libfetch.

* Detect undefined PATH_MAXAllan McRae2010-12-29
| | | | | | | | | | | | | POSIX does not require PATH_MAX be defined when there is not actual limit to its value. This affects HURD based systems. Work around this by defining PATH_MAX to 4096 (as on Linux) when this is not defined. Also, clean up inclusions of limits.h and remove autoconf check for this header as we do not use macro shields for its inclusion anyway.

* improve download_internal error messagesXavier Chantry2009-12-13
| | | | | | | | | | | | | | | download_internal is supposed to always set pm_errno but did not in many cases. The most important (and tested) change is the one concerning fetchStat. This is typically where the code will fail when the network is down for example. Before commit d2dbb04a9af7a18da, this fetchStat call did not exist and the same kind of errors would be encountered in the fetchXGet call that follows. I just copied the error printing to restore the old behavior. Signed-off-by: Xavier Chantry <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
* download: major refactor to address lingering issuesDan McGee2009-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sorry for this being such a huge patch, but I believe it is necessary for quite a few reasons which I will attempt to explain herein. I've been mulling this over for a while, but wasn't super happy with making the download interface more complex. Instead, if we carefully order things in the internal download code, we can actually make the interface simpler. 1. FS#15657 - This involves `name.db.tar.gz.part` files being left around the filesystem, and then causing all sorts of issues when someone attempts to rerun the operation they canceled. We need to ensure that if we resume a download, we are resuming it on exactly the same file; if we cannot be almost postive of that then we need to start over. 2. http://www.mail-archive.com/pacman-dev@archlinux.org/msg03536.html - Here we have a lighttpd bug to ruin the day. If we send both a Range: header and If-Modified-Since: header across the wire in a GET request, lighttpd doesn't do what we want in several cases. If the file hadn't been modified, it returns a '304 Not Modified' instead of a '206 Partial Content'. We need to do a stat (e.g. HEAD in HTTP terms) operation here, and the proceed accordingly based off the values we get back from it. 3. The mtime stuff was rather ugly, and relied on the called function to write back to a passed in reference, which isn't the greatest. Instead, use the power of the filesystem to contain this info. Every file downloaded internally is now carefully timestamped with the remote file time. This should allow the resume logic to work. In order to guarantee this, we need to implement a signal handler that catches interrupts, notifies the running code, and causes it to set the mtimes on the file. It then rethrows the signal so the pacman signal handler (or any frontend) works as expected. 4. We did a lot of funky stuff in trying to track the DB last modified time. It is a lot easier to just keep the downloaded DB file around and track the time on that rather than in a funky dot file. It also kills a lot of code. 5. For GPG verification of the databases down the road, we are going to need the DB file around for at least a short bit of time anyway, so this gets us closer to that.
