win32: use explicit path to "python.exe" only if it exists Before this patch, "hg.bat" for Windows environment always uses "%~dp0..\python" as explicit path to "python.exe". This path may not be valid in some cases. For example, on the environment using "virtualenv" python package, both "python.exe" and "hg.bat" are placed in the same directory. In this case, "python.exe" should be found on PATH, because virtualenv activation script puts "python.exe" on the PATH. This patch uses explicit path to "python.exe" only if it exists, and expects that "python.exe" can be found on PATH otherwise. 2013-04-25 20:12:03 +04:00			`rem Use a full path to Python (relative to this script) if it exists,`

hg.bat: return exit code explicitly for indirect invocation When "hg.bat" is invoked via interactive shell "cmd.exe" on Windows, it can store own exit code into ERRORLEVEL correctly, regardless of explicit "exit" statement in it: "cmd.exe" seems to hold ERRORLEVEL updated by the last command in the batch file (= "python hg", in "hg.bat" case). On the other hand, "hg.bat" is invoked indirectly via "subprocess.Popen" (e.g. shell alias, hooks, hgclient and so on), the parent process always receives exit code 0 from spawned "hg.bat": batch files on Windows seem not to be really spawned like as shell scripts on UNIX, but to be executed in the "cmd.exe" process. This patch returns exit code explicitly for indirect invocation. "/b" should be specified for "exit" to prevent "cmd.exe" from being terminated when "hg.bat" is invoked interactively from it. 2015-01-21 18:07:06 +03:00
