revlog: extract first byte of revlog with a slice so it's portable

revsetlang: slice out single bytes instead of indexing For portability with Python 3.

lock: use %d to format integer into a bytestring

parser: use %d instead of %s for interpolating error position Error position is an int, so we should use %d instead of %s. Fixes failures on Python 3.

manifest: unbreak pure-python manifest parsing on Python 3

context: use portable construction to verify int parsing

ui: portably bytestring-ify url object

scmutil: fix key generation to portably bytestringify integer

branchmap: stringify int in a portable way We actually need a bytes in Python 3, and thanks to our nasty source loader this will portably do the right thing.

branchmap: don't use buffer() on Python 3 This is certainly slower than the Python 2 code, but it works, and we can revisit it later if it's a problem.

py3: use bytearray() instead of array('c', ...) constructions Portable from 2.6-3.6.

summary: don't explicitly str() something we're about to %s str() is wrong on Python 3 here, and %s implicitly calls str() anyway, so this was just extra dancing for no reason.

context: implement both __bytes__ and __str__ for Python 3 They're very similar, for obvious reasons.

context: work around `long` not existing on Python 3 I can't figure out what this branch is even trying to accomplish, and it was introduced in ac89a23ca814 which doesn't really shed any insight into why longs are treated differently from ints.

phases: explicitly evaluate list returned by map On Python 3 map() returns a generator, which bool()s to true even if it had an empty input set. Work around this by using list() on the map() result.

ui: check for --debugger in sys.argv using r-string to avoid bytes on py3 Our source loader was errantly turning this --debugger into a bytes, which was then causing me to still get a pager when I was using the debugger on py3. That made life hard.

minirst: use bytes.strip instead of str.strip bytes.strip exists in Python 2.6 and Python 2.7 also.

smcposix: pass unicode as first argument to array.array This is an instance where we can safely convert the first argument, rest are the cases except one where we are using 'c' which is not there in Python 3. So that needs to be handled differently. This will help in making `hg help` run on Python 3.

util: pass encoding.[encoding|encodingmode] as unicodes We need to pass str to encode() and decode().

minirst: make encoding.encoding unicodes to pass into encode() and decode()

minirst: make regular expressions bytes

setup: convert setupversion to unicode Something deep in the bowels of distutils expects "version" passed to setup() to be a str/unicode. So, convert the type. This still works on Python 2 because the string is ascii and an implicit coercion back to str/bytes should work without issue. If it does cause problems, we can always make the unicode conversion dependent on running Python 3. This change makes `python3.5 setup.py install` work.

util: add debugstacktrace depth limit Useful when you don't care about the start of the stack, but only want to see the last entries.

util: strip trailing newline from debugstacktrace message This makes the function more convenient to use as drop-in replacement for ui.write & co.

tests: rework util.debugstacktrace tests Prepare for adding another test.

vfs: use repo.vfs.rename

vfs: use repo.vfs.unlinkpath

merge: use repo.wvfs.unlinkpath

vfs: use repo.wvfs.unlinkpath

policy: try and always have a bytes for module policy debuginstall now runs cleanly in Python 3.

init: zstd is already python3-ready, so don't run it through our importer

config: guard against setconfig specifying unicode values on py3 This was leading to some difficult to trace problems because the values were set in one place, but then blew up much later in the program. Exploding violently with an assertion seems reasonable here.

dispatch: enforce bytes when converting boolean flags to config items This fixes --verbose on Python 3.

py3: add a test that proves %include and missing-extension code works

extensions: tapdance to get reasonable import error formatting I'm not thrilled with this, but it seems to work.

rebase: abort if *any* commit in rebase set is public

merge with stable

httpconnection: rename config to groups Because that is what it is.

httpconnection: don't use dict() Not sure the history here. But we don't do this elsewhere.

formatter: set _first on formatter, not ui The _first field is used for tracking when to emit a separator between items. It seems like it's clearly formatter state, not ui state, so let's move it there.

rebase: unhide original working directory node as well (issue5219) By including the working directory revision at the start of rebase in the repo._rebaseset, we make sure it's not hidden when we update back to it at the end of the rebase. This feels like abusing the set a bit given its name (_rebaseset), but I couldn't think of another name that's clearly better.

rebase: pass in a regular set to _setrebasesetvisibility() Trivial refactoring to simplify the next patch.

tests: demonstrate broken rebase from obsolete commit This shows the bug I reported in issue 5219.

treemanifest: make node reuse match flat manifest behavior In a flat manifest, a node with the same content but different parents is still considered a new node. In the current tree manifests however, if the content is the same, we ignore the parents entirely and just reuse the existing node. In our external treemanifest extension, we want to allow having one treemanifest for every flat manifests, as a way of easeing the migration to treemanifests. To make this possible, let's change the root node treemanifest behavior to match the behavior for flat manifests, so we can have a 1:1 relationship. While this sounds like a BC breakage, it's not actually a state users can normally get in because: A) you can't make empty commits, and B) even if you try to make an empty commit (by making a commit then amending it's changes away), the higher level commit logic in localrepo.commitctx() forces the commit to use the original p1 manifest node if no files were changed. So this would only affect extensions and automation that reached passed the normal localrepo.commit() logic straight into the manifest logic.

help: update help.internalstable for new censor docs
