Heredocs are usually fed to other commands and
shouldn't follow the standard conventions of shell
commands.
This restores the old behaviour of how heredocs
were handled in old-style test files.
Merely creating and using a generator has a measurable impact,
particularly since the common case for stream_out is generators that
yield just once. Avoiding generators improves stream_out performance
by about 7%.
brendan mentioned on IRC that b64decode raises a TypeError too, but while the
previous exception type may be better in general, it is much easier to make it
behave like the related C code and changes nothing for mercurial itself.
When the contents of .hgsubstate are stale (either because they've
manually been tweaked or partial updates have confused it), we get
confused about whether it actually needs committing.
So instead, we actively consult the parent's substate and compare it
the actual current state when deciding whether it needs committing.
Side effect: lots of "committing subrepo" messages that didn't
correspond with real commits disappear.
This change is fairly invasive for a fairly obscure condition, so it's
kept on the default branch.
The ``discovery.prepush`` function was doing multiple things not related to
discovery. This changeset move some code into the ``localrepo.push`` method. The
old ``discovery.prepush`` function jobs is now restricted to checking for
multple head creation. It was then renamed ``discovery.checkheads``.
This new ``discovery.checkheads`` function may receive several other changes in
the future but we are a bit too much near the freeze for a wider refactoring.
It wasn't obvious from the code how qsave mocked around with .hg/patches and
.hg/patches.? and what was going on.
This makes it more explicit so it will survive future refactorings.
The outgoing object gains an "excluded" members holding all changesets which
were excluded because there where secret.
The core discovery code now remove secret changeset from discovery by default.
This means that any command relying on discovery will exclude secret changeset.
Most notable one are outgoing and bundle. (But bundle with and explicit
``--base`` still allow to bundle outgoing changeset.
check-code has fine warning checks, but they are a bit noisy and nobody used
them.
Now the warnings will be run in the test suite, where a list of accepted
warnings will be maintained.
Those who introduce or touch a line with a warning will now have to update the
whitelist ... or fix the warning.
