test-basic: make test compatible with chg The error codes returned when writing to /dev/full are different after the first failure with and without '--chg' option. Therefore, this commit conditionally handles the error codes as appropriate. Test Plan: Ran the test 'test-basic.t' with and without '--chg' option.

zeroconf: do not crash if socket being read is closed by another thread In zeroconf/__init__.py, there is: server = Zeroconf.Zeroconf(ip) l = listener() Zeroconf.ServiceBrowser(server, "_hg._tcp.local.", l) time.sleep(1) server.close() `server.close()` closes the underlying socket while the `ServiceBrowser` may still have a background thread reading the socket. There could be a race condition where the reading thread reads the closed socket, resulting in EBADF crash. This patch catches the exception. This makes test-paths.t pass with chg.

test-revlog-mmapindex: make it compatible with chg The test misses an explicit flush(). Differential Revision: https://phab.mercurial-scm.org/D918

test-profile: gate chg-incompatible part with '#if chg' chg has a different extension loading logic, which affects the profiler extension test case. Gate the block with '#if chg' so the test passes with chg. Differential Revision: https://phab.mercurial-scm.org/D916

test-logtoprocess: make it compatible with chg chg runs more commands and outputs more lines. This patch matches them. Differential Revision: https://phab.mercurial-scm.org/D914

test-globalopts: make the test compatible with chg The test fails when run with the '--chg' option. Therefore, this commit modifies the test to make it compatible with chg. Test Plan: Ran 'test-globalopts.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D913
