* Lands http://codereview.chromium.org/99349 for Ryan.sky@chromium.org2009-05-041-0/+2
| | | | | | | | | | | | | | Comments from Ryan: Some small changes to get chromium building on ARM. I tested these using the standard Linux tool chain and crosstools-ng. BUG=none TEST=none Review URL: http://codereview.chromium.org/99365 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@15241 0039d316-1c4b-4281-b951-d872f2087c98
* POSIX: Add a macro for handling EINTR.agl@chromium.org2009-05-011-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On POSIX systems, system calls can be interrupted by signals. In this case, they'll return EINTR, indicating that the system call needs to be restarted. (The situation is a little more complicated than this with SA_RESTART, but you can read man 7 signal if you like.) The short of it is that you need to catch EINTR and restart the call for these system calls: * read, readv, write, writev, ioctl * open() when dealing with a fifo * wait* * Anything socket based (send*, recv*, connect, accept etc) * flock and lock control with fcntl * mq_ functions which can block * futex * sem_wait (and timed wait) * pause, sigsuspend, sigtimedwait, sigwaitinfo * poll, epoll_wait, select and 'p' versions of the same * msgrcv, msgsnd, semop, semtimedop * close (although, on Linux, EINTR won't happen here) * any sleep functions (careful, you need to handle this are restart with different arguments) We've been a little sloppy with this until now. This patch adds a macro for dealing with this and corrects every case of these system calls (that I found). The macro is HANDLE_EINTR in base/eintr_wrapper.h. It's safe to include on Windows and is a no-op there. On POSIX, it uses GCC magic to return the correct type based on the expression and restarts the system call if it throws EINTR. And you can use it like: HANDLE_EINTR(close(fd)); Or: ssize_t bytes_read = HANDLE_EINTR(read(fd, buffer, len)); *BEWARE* that it will evaluate the argument multiple times, so this is not safe: HANDLE_EINTR(close(FireMissiles())); http://groups.google.com/group/chromium-dev/browse_thread/thread/41a35b2a457d73a0 http://codereview.chromium.org/100225 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@15102 0039d316-1c4b-4281-b951-d872f2087c98
* Print backtraces on FATAL log messages in debug mode.ajwong@chromium.org2009-04-241-4/+34
| | | | | | | | This provides basic support for looking up backtrace information on GNU libc systems and in Windows. The code is only enabled for FATAL log messages in debug mode. In a release build, it is unlikely that symbols will be available making the backtrace less useful.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the moment, it only works on Linux, although it should be pretty easy to get it working on Mac with __builtin_return_address and __builtin_frame_address. It will mostly fail to resolve functions. Use this wrapper script: import os import sys import subprocess import re address = re.compile('.*\[(0x[0-9a-fA-F]{4,8})\].*') if __name__ == '__main__': p = subprocess.Popen(sys.argv[1:], stderr = subprocess.STDOUT, stdout = subprocess.PIPE) addr2line = subprocess.Popen(['addr2line', '-e', sys.argv[1], '-f', '-C', '-s'], stdout = subprocess.PIPE, stdin = subprocess.PIPE) for line in p.stdout.readlines(): m = address.match(line); if m is not None: addr2line.stdin.write(m.groups()[0] + '\n') function = addr2line.stdout.readline()[:-1] location = addr2line.stdout.readline()[:-1] sys.stdout.write('%s (%s)\n' % (function, location)) else: sys.stdout.write(line) Review URL: http://codereview.chromium.org/18303 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@8218 0039d316-1c4b-4281-b951-d872f2087c98
