From 4105ebb6ed85aaffec5e4469a939945fb9eea066 Mon Sep 17 00:00:00 2001 From: athenian200 Date: Tue, 1 Oct 2019 18:28:10 -0500 Subject: MoonchildProductions#1251 - Part 4: Core build system changes, lots of libevent/IPC junk. This is mostly ifdefs, but as you can see, Solaris is actually a lot like Linux. They're both more SysV than BSD at core, and most of the differences have more to do with Solaris not using glibc than anything else. I still need to audit a lot of these changes and understand why they're needed and what the alternative approaches are. After this patch, most of the core functionality needed to build Solaris is here. --- ipc/chromium/src/base/message_pump_glib.cc | 19 ++++++++++++++++++- 1 file changed, 18 insertions(+), 1 deletion(-) (limited to 'ipc/chromium/src/base/message_pump_glib.cc') diff --git a/ipc/chromium/src/base/message_pump_glib.cc b/ipc/chromium/src/base/message_pump_glib.cc index 36ebfdd69..a5e719c72 100644 --- a/ipc/chromium/src/base/message_pump_glib.cc +++ b/ipc/chromium/src/base/message_pump_glib.cc @@ -9,6 +9,9 @@ #include #include +#if defined(OS_SOLARIS) +#include +#endif #include #include @@ -131,6 +134,12 @@ MessagePumpForUI::MessagePumpForUI() // Create our wakeup pipe, which is used to flag when work was scheduled. int fds[2]; CHECK(pipe(fds) == 0); +#if defined(OS_SOLARIS) + int flags = fcntl(fds[0], F_GETFL,0); + if (flags == -1) + flags = 0; + fntl(fds[0], F_SETFL, flags | O_NDELAY); +#endif wakeup_pipe_read_ = fds[0]; wakeup_pipe_write_ = fds[1]; wakeup_gpollfd_->fd = wakeup_pipe_read_; @@ -238,11 +247,15 @@ bool MessagePumpForUI::HandleCheck() { // whether there was data, so this read shouldn't block. if (wakeup_gpollfd_->revents & G_IO_IN) { pipe_full_ = false; - +#ifndef OS_SOLARIS char msg; if (HANDLE_EINTR(read(wakeup_pipe_read_, &msg, 1)) != 1 || msg != '!') { NOTREACHED() << "Error reading from the wakeup pipe."; } +#else + char buf[32]; + while (HANDLE_EINTR(read(wakeup_pipe_read_, &buf, 32))); +#endif // Since we ate the message, we need to record that we have more work, // because HandleCheck() may be called without HandleDispatch being called // afterwards. @@ -311,6 +324,10 @@ void MessagePumpForUI::ScheduleWork() { // variables as we would then need locks all over.
