tests: invoke printenv.py via sh -c for test portability
On Windows platform, invoking printenv.py directly via hook is
problematic, because:
- unless binding between *.py suffix and python runtime, application
selector dialog is displayed, and running test is blocked at each
printenv.py invocations
- it isn't safe to assume binding between *.py suffix and python
runtime, because application binding is easily broken
For example, installing IDE (VisualStudio with Python Tools, or
so) often requires binding between source files and IDE itself.
This patch invokes printenv.py via sh -c for test portability. This is
a kind of follow up for d19787db6fe0, which eliminated explicit
"python" for printenv.py. There are already other 'sh -c "printenv.py"'
in *.t files, and this fix should be reasonable.
This changes were confirmed in cases below:
- without any application binding for *.py suffix
- with binding between *.py suffix and VisualStudio
This patch also replaces "echo + redirection" style with "heredoc"
style, because:
- hook command line is parsed by cmd.exe as shell at first, and
- single quotation can't quote arguments on cmd.exe, therefore,
- "printenv.py foobar" should be quoted by double quotation, but
- nested quoting (or tricky escaping) isn't readable

# Helper script used for generating history and working copy files and content. # The file's name corresponds to its history. The number of changesets can # be specified on the command line. With 2 changesets, files with names like # content1_content2_content1-untracked are generated. The first two filename # segments describe the contents in the two changesets. The third segment # ("content1-untracked") describes the state in the working copy, i.e. # the file has content "content1" and is untracked (since it was previously # tracked, it has been forgotten). # # This script generates the filenames and their content, but it's up to the # caller to tell hg about the state. # # There are two subcommands: # filelist <numchangesets> # state <numchangesets> (<changeset>|wc) # # Typical usage: # # $ python $TESTDIR/generate-working-copy-states.py state 2 1 # $ hg addremove --similarity 0 # $ hg commit -m 'first' # # $ python $TESTDIR/generate-working-copy-states.py state 2 1 # $ hg addremove --similarity 0 # $ hg commit -m 'second' # # $ python $TESTDIR/generate-working-copy-states.py state 2 wc # $ hg addremove --similarity 0 # $ hg forget *_*_*-untracked # $ rm *_*_missing-* from __future__ import absolute_import, print_function import os import sys # Generates pairs of (filename, contents), where 'contents' is a list # describing the file's content at each revision (or in the working copy). # At each revision, it is either None or the file's actual content.
