check-code: separate warnings to avoid repetitive str.startswith

atomictempfile: rewrite docstring to clarify rename() vs. close().

atomictempfile: avoid infinite recursion in __del__(). The problem is that a programmer using atomictempfile directly can make an innocent everyday mistake -- not enough args to the constructor -- which escalates badly. You would expect a simple TypeError crash in that case, but you actually get an infinite recursion that is surprisingly difficult to kill: it happens between __del__() and __getattr__(), and Python does not handle infinite recursion from __del__() well. The fix is to not implement __getattr__(), but instead assign instance attributes for the methods we wish to delegate to the builtin file type: write() and fileno(). I've audited mercurial.* and hgext.* and found no users of atomictempfile using methods other than write() and rename(). I audited third-party extensions and found one (snap) passing an atomictempfile to util.fstat(), so I also threw in fileno(). The last time I submitted a similar patch, Matt proposed that we make atomictempfile a subclass of file instead of wrapping it. Rejected on grounds of unnecessary complexity: for one thing, it would make the Windows implementation of posixfile quite a bit more complex. It would have to become a subclass of file rather than a simple function -- but since it's written in C, this is non-obvious and non-trivial. Furthermore, there's nothing wrong with wrapping objects and delegating methods: it's a well-established pattern that works just fine in many cases. Subclassing is not the answer to all of life's problems.

run-tests: display diff before prompting with --interactive

check-code: warn about naked except clauses

eliminate various naked except clauses

run-tests: fix some missing i/o locks

run-tests: add a lock for console I/O

run-tests: switch timeout handling from alarm to helper thread This should be slightly more portable than signals and be compatible with threaded dispatch.

run-tests: add locking on results struct

color: code simplification

test-status-color: fix terminfo code compatibility problem On a linux host in xterm mode, 'none' is translated to: \x1b[m\x1b(B While it is the following on osx: \x1b(B\x1b[m Take advantage of the new color.color.X option to force it to a common value.

run-tests: keep a list of passed tests

run-tests: move keyword checking into runone

run-tests: add ignores list

run-tests: move interactive handling into runone

color: add support for terminfo-based attributes and color Using terminfo instead of hard-coding ECMA-48 control sequences provides a greater assurance that the terminal codes are correct for the current terminal type; not everything supports the ANSI escape codes. It also allows us to use a wider range of colors when a terminal emulator supports it (such as 16- or 256-color xterm), and a few more non-color attributes, such as the ever-popular blink.
