* Changes needed for MacOS X 10.4 support.maf@google.com2009-09-151-20/+28
| | | | | | | | Add "support_macosx_10_4" option to common.gypi that causes it to change deployment target, and define a new preprocessor symbol on the Mac build. Setting this flag to true is harmless on non Mac builds and has no effect. Make various changes to source files where they modify their behavior in the presence of the new preprocessor symbol to become 10.4 compatible.

* 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
