* Fix hang in waitpid, exposed by r310. Patch from Enrico Scholzgraham.gower2009-11-191-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <enrico.scholz@informatik.tu-chemnitz.de>, his analysis follows. libbb/unarchive.c: prevent opkg hang when subprocess is stuck in a write() call on a filled pipe and main process (which assumes that end of data from pipe has been reached) waits for this died subprocess. This patch swaps the original wait(pid) + close(pipe) sequencse so that pipe is closed first. The 'ar' code path has been fixed too by breaking the loop when requested data have been found. Previously, the loop continued at the (wrongly calculated) next position in the stream. The patch moves the stream cleanup at a better place. Variable declarations were moved to inner scopes too to ease detection of broken deallocation. NOTE: the | f = fdopen(...); | while (... /* do fread(f) */ ...) { /* ==1== */ | /* this is done in gz_open() */ | pid = fork(); | if (pid == 0) { | fread(f); /* ==2== */ | _exit(0); | } | } code looks problematic because '==2==' might update f's internal buffer. As ==2== is done in an own process, these changes are not seen by ==1==. It works only because gz_open() is called not more than one time and the loops break (after the patch). git-svn-id: http://opkg.googlecode.com/svn/trunk@340 e8e0d7a0-c8d9-11dd-a880-a1081c7ac358

| | | | | | | | | | | | | | | | | | Frans Meulenbroeks http://groups.google.com/group/opkg-devel/browse_thread/thread/23c3557277de0f2e If a file name in a tar archive is exactly 100 bytes long the name field is completely filled and there is no terminating null byte; so extraction of the file will yield a name that is extended with the mode (e.g. 000644). The attached patch cures it although there might be better solutions. The problem is also in busybox tar and reported there too.

| | | | | | | | | | | | | | | | | | | | | | ---------- This patchset updates the libbb stuff to use a vfork() version of gz_open, called gzvopen. This is done because a standard fork will duplicate the entire address space. This will invoke the OOM (out of memory) killer on small-memory machines, because most often by the time we unzip any package, we've read the entire package database into memory already. By using vfork() and immediatly execing the external gunzip utility, we avoid the need to clone the entire address space. Yes, this is actually **LESS** efficient than the original way! But there is no way to (currently) dodge the OOM killer on a per-process basis, so the alternatives are to either change the OOM killer behavior system-wide, or to use this workaround.
