Before this patch, using ui.configint() prevents perf.py from measuring performance with Mercurial earlier than 1.9 (or 12e7e9fbf243), because ui.configint() isn't available in such Mercurial, even though there are some code paths for Mercurial earlier than 1.9 in perf.py. For example, setting "_prereadsize" attribute in perfindex() and perfnodelookup() is effective only with hg earlier than 1.8 (or 1299f0c14572). This patch replaces ui.configint() invocations by newly introduced getint(). This patch also adds check-perf-code.py an extra check entry to detect direct usage of ui.configint() in perf.py. BTW, this patch doesn't choose adding configint() method at runtime by replacing ui.__class__ like below, even though this is the recommended way to modern Mercurial extensions. def uisetup(ui): if not util.safehasattr(ui, 'configint'): class uiwrap(ui.__class__): def configint(self, section, name, ....): .... ui.__class__ = uiwrap Because changes to ui.__class__ by uisetup() of loaded extension have been propagated since 1.6.1 (or 07a6e7bd0cc1), the recommended way above doesn't work as expected with Mercurial earlier than it.
