As per IRC discussion and suggestion by Augie, we should not allow bare `hg
uncommit` on dirty working directory.

Valid part names are restricted to [a-zA-Z0-9_:-]+, so I'm not worried
about having quoting present in places where we should have
predominantly valid part names. This will significantly ease the
Python 3 transition, and simultaneously isn't a BC because this is
only in error messages that should never be shown.
`lastui` decides where (where is the `.hg`) to use if the current `ui`
object does not have a `_bbrepo` associated. Previously it only gets set in
`ui.log`, which means unless a `ui` with repo associated calls `log` with
tracked event, blackbox does not know where to write its log. This patch
makes `reposetup` set `lastui` so it so we could log some more events (see
test changes).

It seems cleaner to just remove `_partialinit`, `copy`, `__init__`. This
patch makes it so by using `getattr` in `log` so those fields do not need to
be existed.

Previously revset weight is hardcoded and cannot be modified. This patch
moves it to predicate so newly registered revsets could define their weight
to properly give static optimization some hint.
Differential Revision: https://phab.mercurial-scm.org/D657
`_optimize` calculates weights of subtrees. "small" affects some weight
calculation (either 1 or 0.5). The weights are now only useful in `and`
optimization where we might swap two arguments and use `andsmally`.
In the real world, it seems unlikely that revsets with weight of 0.5 or 1
matters the `and` order optimization. I think the important thing is to get
weights of expensive revsets right (ex. `contains`).
This patch removes the `small` argument to simplify the interface.
As for choosing between 0.5 vs 1, things returning a single revision
(`ancestor`, `string`) has a weight of 0.5. Things returning multiple
revisions returns 1. This could be sometimes useful in the `andsmally`
optimization, ex.
(((:)-2) & expensive()) & ((1-2) & expensive())
^^^ ^
^^^^^^^ ^^^^^
^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^
weight=1 weight=0.5
would have an `andsmally` optimization so `1-2` gets executed first, which
seems to be desirable.

As far as I can tell, default values are evaluated far earlier on
Python 3.6 than 2.7, meaning we've got to be more careful about when
we read the defaults dictionary for the kwarg defaults. Sigh.
With this change, test-run-tests.t is significantly less of a mess
under 3.6.
I've poked at this on and off several times, and I can't figure out
what regressed. Let's kick this out of the whitelist for now so that
we can get the *rest* of our progress covered by the buildbots.
Now that the part processing loop is tiny, let's move it to a separate function.
This will allow extensions to completely replace the part processing logic,
without having to replace the overall bundle processing logic or the stream
maintenance logic.
This will be useful for the infinitepush extension, so it can completely take
over receiving a bundle and rerouting it to a side store. This will also make it
easier to upstream the infinitepush functionality later.

As part of refactoring bundle part processing let's move handler validation to
its own function.
Differential Revision: https://phab.mercurial-scm.org/D707
The processpart function also did some stream maintenance, so let's move it to
the part iterator as well, as part of moving all part iteration logic into the
class.
There is one place processpart is called outside of the normal loop, so we
manually handle the seek there.
The now-empty try/finally will be removed in a later patch, for ease of review.

This is a trivial backport of 9f516a26a962 performed by
augie@google.com, but the change is still really Durham's not mine, so
I [augie] am leaving him as the author.
It seems like we used to pick the oldest possible version of the
changegroup to use for bundles created by the repair module (used
e.g. by "hg strip" and for temporary bundles by "hg rebase"). I tried
to preserve that behavior when I created the changegroup.safeversion()
method in 77f74106b264 (changegroup: introduce safeversion(),
2016-01-19).
However, we have recently chagned our minds and decided that these
commands are only used locally and downgrades are unlikely. That
decicion allowed us to start adding obsmarker and phase information to
these bundles. However, as the bug report shows, it means we get
different behavior e.g. when generaldelta is not enabled (because when
it was enabled, it forced us to use bundle2). The commit that actually
caused the reported bug was 26d535788092 (strip: include phases in
bundle (BC), 2017-06-15).
So, since we now depend on having more information in the bundles,
let's make sure we instead pick the newest possible changegroup
version.

In addition to a test case for the direct problem described in the bug
report, this also adds a test case showing how obsmarkers can also get
lost when not using generaldelta.

Users with custom [diff] configuration most certainly didn't intend it to make
mq lose changes. It could:
* git is handled perfectly fine.
* nobinary could make mq leave some files out from the patches.
* noprefix could make mq itself (and probably also other tools) fail to apply
patches without the usual a/b prefix.
* ignorews, ignorewsamount, or ignoreblanklines could create patches with
missing whitespace that could fail to apply correctly.
Thus, when refreshing patches, use patch.difffeatureopts, optionally with git
as before, but without the config options for whitespace and format changing
that most likely will cause loss or problems.
(patch.diffopts is just patch.difffeatureopts with all options enabled and can
be replaced with that.)
It can be useful for extensions to be able to produce the shortest
unambiguous hash (including the in-tree "show" extension). That logic
is currently inside the shortest() template function. Let's move it
out of the templater. I've put it on revlog since it's closely related
to revlog._partialmatch. We may also want a convenience method on
context, but I'll leave that for a later patch.

I've tripped on this several times now, and am tired of debugging. Now
the header parts are part of the error message when the ''.join()
fails, which makes debugging obvious.
This was the original intent, but I bungled the logic. Otherwise if there is a
certificate chain issue, the repository can't be cloned in order for there to be
a repo object. I think I missed this case because I was inside of a Mercurial
clone as I was originally developing and testing this.
This is a regression caused by 10c1efcbeb1e. Code prior to 10c1efcbeb1e
seems to miss the "\ No newline at end of file" line.

As Augie reported in the bug, the current heuristic of choosing the
best tag of a merge commit by taking the one with newest tag (in terms
of tagging date) currently fails in the Mercurial repo itself. Copying
the example from Yuya:
$ hg glog -T '{node|short} {latesttag}+{latesttagdistance}\n' \
-r '4.2.3: & (merge() + parents(merge()) + tag())'
o cc59efae4cc0 4.2.3+5
|\
| o 06f60e88fc3a 4.2.3+4
| |\
| | o c191a9eb0b10 4.3-rc+109
| | |
| | ~
o | 49ada93fdc10 4.3.1+2

o | 229937197835 4.3.1+0

o 6a83ad94c0f2 4.2.3+3
|\
| ~
o 8e9dcdd1de74 4.2.3+2
:
o 525f2b18248f 4.2.3+0

It seems to me like the best choice is the tag with the smallest
number of changes since it (across all paths, not the longest single
path). So that's what this patch does, even though it's
costly. Best-of-5 timings for Yuya's command above shows a slowdown
from 1.293s to 1.610s. We can optimize it later.

45345e9870c3 and b30126fa95bc refactored ui methods to no longer
silently swallow some IOError instances. This is arguably the
correct thing to do. However, it had the unfortunate side-effect
of causing StdioError to bubble up to sensitive code like
transaction aborts, leading to an uncaught exceptions and failures
to e.g. roll back a transaction. This could occur when a remote
HTTP or SSH client connection dropped. The new behavior is
resulting in semi-frequent "abandonded transaction" errors on
multiple high-volume repositories at Mozilla.
This commit effectively reverts 45345e9870c3 and b30126fa95bc to
restore the old behavior.
I agree with the principle that I/O errors shouldn't be ignored.
That makes this change... unfortunate. However, our hands are tied
for what to do on stable. I think the proper solution is for the
ui's behavior to be configurable (possibly via a context manager).
During critical sections like transaction rollback and abort, it
should be possible to suppress errors. But this feature would not
be appropriate on stable.
