tests: add support for inline doctests in test files This adds doctest like syntax to .t files, that can be interleaved with regular shell code: $ echo -n a > file >>> print open('file').read() a >>> open('file', 'a').write('b') $ cat file ab The syntax is exactly the same as regular doctests, so multiline statements look like this: >>> for i in range(3): ... print i 0 1 2 Each block has its own context, i.e.: >>> x = 0 >>> print x 0 $ echo 'foo' foo >>> print x will result in a NameError. Errors are displayed in standard doctest format: >>> print 'foo' bar --- /home/idan/dev/hg/default/tests/test-test.t +++ /home/idan/dev/hg/default/tests/test-test.t.err @@ -2,3 +2,16 @@ > >>> print 'foo' > bar > EOF + ********************************************************************** + File "/tmp/tmps8X_0ohg-tst", line 1, in tmps8X_0ohg-tst + Failed example: + print 'foo' + Expected: + bar + Got: + foo + ********************************************************************** + 1 items had failures: + 1 of 1 in tmps8X_0ohg-tst + ***Test Failed*** 1 failures. + [1] As for the implementation, it's quite simple: when the test runner sees a line starting with '>>>' it converts it, and all subsequent lines until the next line that begins with '$' to a 'python -m heredoctest <<EOF' call with the proper heredoc to follow. So if we have this test file: >>> for c in 'abcd': ... print c a b c d $ echo foo foo It gets converted to: $ python -m heredoctest <<EOF > >>> for c in 'abcd': > ... print c > a > b > c > d > EOF $ echo foo foo And then processed like every other test file by converting it to a sh script.

import: wrap a transaction around the whole command Now 'rollback' after 'import' is less surprising: it rolls back all of the imported changesets, not just the last one. As an extra added benefit, you don't need 'rollback -f' after 'import --bypass', which was an undesired side effect of fixing issue2998 (59e8bc22506e).. Note that this is a different take on issue963, which complained that rollback after importing multiple patches returned the working dir parent to the starting point, not to the second-last patch applied. Since we now rollback the entire import, returning the working dir to the starting point is entirely logical. So this change also undoes a732eebf1958, the fix to issue963, and updates its tests accordingly. Bottom line: rollback after import was weird before issue963, understandable since the fix for issue963, and even better now. [ original upstream message ]
