* linux (and some posix): multiprocess plugins compiling.evan@chromium.org2009-04-231-2/+2
| | | | | | | | | | | | | | | | | | | The goal of this change is to *not* make any behavioral change, but to instead just get all the plugin-related files linking on Linux with a bunch of NOTIMPLEMENTED()s in the appropriate places. It's enormous enough already without any refactorings or new features. Changes include: - Lots of gcc warning fixes. - Use portable replacements for Windows-specific functions (_strdup, etc.). - Use TransportDIB instead of just shared memory in the plugin messaging. Note that this is not fleshed out on Linux and on Windows it just hacks in the existing handles so there should be no functional change. - Fix --plugin-launcher to use cross-platform APIs.

* Remove histogram connection to base classes in stats_counterjar@chromium.org2009-04-101-0/+1
| | | | | | | | | | | | | | | | Now that histograms move data from renderer to browser, there is less reason to connect to stats counters. Stats counters were using shared memory, and now they may plausibly use the histogram's IPC mechanism instead to move data to the browser. The first step is remove the inheritance, and teh next (plausible/future) step would be to implement counters as histograms with only one bucket. r=mbelshe Review URL: http://codereview.chromium.org/66029 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@13544 0039d316-1c4b-4281-b951-d872f2087c98

* Use a dedicated command line flag for FIFO IPC channels on POSIX.phajdan.jr@chromium.org2009-02-271-1/+1
| | | | | | | | | | This fixes a problem I hit when porting startup_tests that the controlling startup_tests process didn't use FIFO, and the child chrome process did (and obviously they couldn't communicate).

* POSIX: Rename DescriptorSet to FileDescriptorSetagl@chromium.org2009-02-121-9/+10
| | | | | | | This is just following up on a code review promise. git-svn-id: svn://svn.chromium.org/chrome/trunk/src@9676 0039d316-1c4b-4281-b951-d872f2087c98
* POSIX: Clean up DescriptorSetagl@chromium.org2009-02-121-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | In general, the IPC Message objects are const and the iterator state is a void* kept by the code which is doing the deserialisation. However, now that we have an array of file descriptors, the index of the next file descriptor is part of the iteration state and is kept /inside/ the Message (in the DescriptorSet). This means that it's a mutable member, which is never too nice and also, since the logging functions want to parse a message multiple times, we've had to turn off returning an error when one runs off the end of the array. Also, the Message copy constructor and assignment function alters the /source/ Message, by stealing all of its descriptors This patch encodes the index of each file descriptor on the wire. So the state is moved from inside the DescriptorSet into the serialised data. Additionally, the DescriptorSet is made into a lazyily created scoped_refptr, solving the problems with copying messages.

* OSX: Workaround CMSG_FIRSTHDR bugagl@chromium.org2009-02-121-17/+41
| | | | | | | | | | | | | | | | | | | | | | | On OSX, CMSG_FIRSTHDR will return a pointer into the control buffer space when controllen == 0. We work around by testing for a non-zero controllen before trying to parse control messages. Test case: int main() { struct msghdr msg; msg.msg_control = &msg; msg.msg_controllen = 0; if (CMSG_FIRSTHDR(&msg)) printf("Bug found!\n"); } Review URL: http://codereview.chromium.org/21283 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@9640 0039d316-1c4b-4281-b951-d872f2087c98
* POSIX: Transfer network data using shared memoryagl@chromium.org2009-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch adds the long planned support for sharing memory on POSIX by transporting file descriptors. It largely builds on the shared memory cleanup work by jrg. We move FileDescriptor out of chrome/common/file_descriptor_posix.h and into base/file_descriptor_posix.h. Since all that's left in the chrome/common verion is the DescriptorSet, those files are renamed to descriptor_set.[h|cc]. The SharedMemoryHandle on POSIX then becomes a typedef to a FileDescriptor and thus can be serialised over IPC. After that, it's mostly a case of cleaning up those snippets of code which considered SharedMemoryHandles to be scaler values.

* POSIX: fix file descriptor passingagl@chromium.org2009-02-101-1/+2
| | | | | | | | | The kernel sets msghdr.msg_controllen to the length of the received control data on successful return. Thus, we need to reset this variable to the length of the buffer before each call. git-svn-id: svn://svn.chromium.org/chrome/trunk/src@9471 0039d316-1c4b-4281-b951-d872f2087c98

* FileDescriptor: passing fds over IPCagl@chromium.org2009-02-071-4/+117
| | | | | | | | | This patch introduces a FileDescriptor object which can be included in IPC messages and will perform the magic needed to pass file descriptors over IPC. After some consideration, Windows will continue to do the current DuplicateHandle tricks.

One explicit goal of this change is to *not* deal with the string/wstring issues at the API on POSIX; the functions are the same as before, which means they remain as broken as before.
