Rather than use libevent's own build system, we just build a Chrome
|
|
static library using GYP.
|
|
|
|
1) Run configure and "make event-config.h" on Linux, FreeBSD, Solaris,
|
|
and Mac and copy config.h and event-config.h to linux/, freebsd/,
|
|
solaris/, and mac/ respectively.
|
|
2) Add libevent.gyp.
|
|
3) chromium.patch is applied to make the following changes:
|
|
- Allow libevent to be used without being installed by changing <...>
|
|
#includes to "...".
|
|
- Fix a race condition in event_del.
|
|
- Optimistically assume CLOCK_MONOTONIC is available and fallback if it
|
|
fails, rather than explicitly testing for it.
|
|
- Remove an unneeded variable that causes a -Werror build failure.
|
|
- Add an #ifndef to fix a preprocessor redefined -Werror build failure.
|
|
- Revert the patch from http://sourceforge.net/p/levent/bugs/223/ that
|
|
introduces use-after-free memory corruption when an event callback frees
|
|
the struct event memory.
|
|
- Remove deprecated global variables, event_sigcb and event_gotsig
|
|
(essentially unused) that trigger tsan errors. (crbug/605894)
|
|
4) The directories WIN32-Code and WIN32-Prj are not included.
|
|
5) The configs for android were copied from Linux's which were very close to
|
|
android one with the exception of HAVE_FD_MASK and HAVE_STRLCPY.
|
|
6) Add files to support building with the PNaCl toolchain. Added
|
|
libevent_nacl_nonsfi.gyp for build rule. nacl_nonsfi/config.h and
|
|
nacl_nonsfi/event-config.h are derived from linux/ counterparts.
|
|
nacl_nonsfi/random.c is also added to provide the random() function,
|
|
which is missing in the newlib-based PNaCl toolchain.
|
|
7) Stub out signal.c for nacl_helper_nonsfi. socketpair() will be prohibited
|
|
by sandbox in nacl_helper_nonsfi.
|
|
8) Remove an unnecessary workaround for OS X 10.4 from kqueue.c. It was causing
|
|
problems on macOS Sierra.
