README.mozilla (1763B)
1 This is a clean copy of libevent-2.1.12-stable with the following modifications. 2 3 1. Add the following files: 4 5 - android/event2/event-config.h 6 - bsd/event2/event-config.h 7 - linux/event2/event-config.h 8 - mac/event2/event-config.h 9 - solaris/event2/event-config.h 10 - evconfig-private.h 11 12 These files are taken from libevent-2.1.12-stable built on the development 13 environment indicated by the first path component. You have to run 14 "./configure" and "make" to get all of the pre-processing done. The 15 event-config.h header can then be found in include/event2/ sub-directory and 16 evconfig-private.h can be found in the root source directory. 17 18 You then need to modify the EVENT__SIZEOF_* constants in the generated Linux, 19 Android, and BSD headers to be appropriate for both 32-bit and 64-bit platforms. 20 Mac doesn't need this since only 64-bit is supported. Use __LP64__ to 21 distinguish the two cases. If you get something wrong, the CHECK_EVENT_SIZEOF 22 static assertions in message_pump_libevent.cc will fail. If a new constant is 23 added, also add a static assertion for it to message_pump_libevent.cc. 24 25 You also need to modify the EVENT__HAVE_ARC4RANDOM and EVENT__HAVE_ARC4RANDOM_BUF 26 constants in the generated Linux header to account for the results of the arc4random 27 and arc4random_buf configure checks. 28 29 2. Apply the following patch from ipc/chromium/src/third_party/libevent/patches/: 30 31 - "prevent-use-of-evsig.patch". Prevents using (via intentional crash) any 32 of libevent's signal handling code; see bug 1616462. This isn't strictly 33 required for functionality but it's a local patch we'd like to retain. 34 35 Additionally, be careful to avoid clobbering changes to the various 36 event-config.h files which have been customized over time to avoid 37 various build bustages.
