bundlerepo: assign bundle attributes in bundle type blocks It is a bit wonky to assign the same object to multiple attributes and then possibly overwrite them later. Refactor the code to use a local variable and defer attribute assignment until the final values are ready. This required passing the bundle instance to _handlebundle2part(). The only use of this method I could find is Facebook's treemanifest extension. Since it is a private method, I don't think it warrants an API callout.

bundlerepo: make bundle and bundlefile attributes private These attributes are implementation details and shouldn't be exposed outside the class. .. api:: bundlerepo.bundlerepository.bundle and bundlerepo.bundlerepository.bundlefile are now prefixed with an underscore.

bundlerepo: don't assume there are only two bundle classes exchange.readbundle() can return a type that represents a stream clone bundle. Explicitly handle the bundle1 type and raise a reasonable error message for unhandled bundle types. Differential Revision: https://phab.mercurial-scm.org/D1376

bundlerepo: rename arguments to bundlerepository.__init__ To reflect what they actually are. Differential Revision: https://phab.mercurial-scm.org/D1374

bundlerepo: use suffix variable It looks like the refactor in 702a26fec3e2 attempted to establish this method argument but failed to use it. My editor caught it. Differential Revision: https://phab.mercurial-scm.org/D1373

bundlerepo: make methods agree with base class My editor was complaining about mismatches between method signatures. For methods that are implemented, we change arguments to match the base. For those that aren't, we use variable arguments because it shouldn't matter. Differential Revision: https://phab.mercurial-scm.org/D1372

bundle2: use os.SEEK_* constants Constants make code easier to read than magic numbers. I also threw in an explicit argument in a caller to further increase code comprehension. Differential Revision: https://phab.mercurial-scm.org/D1370

help: adding a topic on flags This is a short topic to explain how command-line flags can be specified. Some users have been confused by hg offerring different flag syntax than some other libraries, so it'd be nice to point them to this rather than explaining it every time.

py3: handle keyword arguments correctly in hgext/patchbomb.py The keys of keyword arguments must be str on Python 3 which is unicode. This patch make sure we pass keyword arguments with keys are str everywhere in this file and access the keys depending on whether they are bytes or str. This patch uses pycompat.{byteskwargs|strkwargs} and somewhere it also added r'' to prevent transformer from adding a b'' over there. Differential Revision: https://phab.mercurial-scm.org/D974

tests: use jshint when available to check .js files

hgweb: fix jshint issues in mercurial.js Everything is pretty self-explanatory except the last hunk, where jshint complains: "Misleading line break before '||'; readers may interpret this as an expression boundary." There is a tweakable called "laxbreak" that allows line breaks before operators, but I think it's fine to simply join this one line and avoid extra config for now (we can cook up and add a sensible .jshintrc later).

exchange: drop unused '_getbookmarks' function The function was introduced in 8491845a75b2 in mid-November 2016 but is never used anywhere in core.

bookmark: use bundle2 debug output in one push tests Having more details about the push process will help to track changes made to the actual exchange.

pull: store binary node in pullop.remotebookmarks The internal representation of bookmark value is binary. The fact we stored 'hex' was an implementation detail from using pushkey. We move the values in 'pullop.remotebookmarks' to binary before adding a way to exchange bookmarks not based on pushkey.

convert: avoid wrong lfconvert defaults by moving configitems to core The `hg lfconvert --to-normal` command uses the convert extension internally to work its magic, but that produced devel-warn messages if the convert extension wasn't loaded by the user. The test in fcd2f9b06629 (modified here) wasn't showing the warnings because the convert extension was loaded via $HGRCPATH. Most of the config options default to None/False, but 'hg.usebranchnames' and 'hg.tagsbranch' are supposed to default to True and 'default' respectively. The first iteration of this was to ui.setconfig() inside lfconvert, to force the convert extension to load. But there really is no precedent for doing this, and check-config complained that 'extensions.convert' isn't documented. Yuya suggested this alternative. This partially backs out 0d5a1175d0f9.

tr-summary: keep a weakref to the unfiltered repository Repoview can have a different life cycle, causing issue in some corner cases. The particular instance that revealed this comes from localpeer. The localpeer hold a reference to the unfiltered repository, but calling 'local()' will create an on-demand 'visible' repoview. That repoview can be garbaged collected any time. Here is a simplified step by step reproduction:: 1) tr = peer.local().transaction('foo') 2) tr.close() After (1), the repoview object is garbage collected, so weakref used in (2) point to nothing. Thanks to Sean Farley for helping raising and debugging this issue.

dispatch: verify result of early command parsing Before, early options were stripped from args, and because of this, some kind of parsing errors weren't reported. For example, $ hg ci -m -Ra file would execute "hg ci -m file" in repository "a". This patch fixes the issue by parsing early options again by real getopt-based parser, and verifying the results. If the early parsing appears wrong, hg just aborts. The current error message seems not nice, and should be improved, maybe in V2 or follow-up. Note that this isn't a security feature because we can still do anything by using shell aliases.

dispatch: convert non-list option parsed by _earlygetopt() to string So we can easily compare it with the corresponding getopt() result. There's a minor behavior change. Before, "hg --cwd ''" failed with ENOENT. But with this patch, an empty cwd is silently ignored. "hg -R ''" has always worked as such, so -R has no BC.

dispatch: add option to not strip command args parsed by _earlygetopt() This allows us to parse the original args later by full-blown getopt() in order to verify the result of the faulty early parsing. Still we need the 'strip=True' behavior for shell aliases. Note that this series is RFC because it seems to change too much to be included in stable release.

dispatch: fix early parsing of short option with value like -R=foo Before, -R=foo was parsed as '-R' 'foo', which disagrees with the standard getopt behavior.

dispatch: abort if early boolean options can't be parsed Perhaps we'll need to restrict the parsing rules of --debugger and --profile, where this patch will help us know why the --debugger option doesn't work. I have another series to extend this feature to --config/--cwd/-R, but even with that, shell aliases can be used to get around the restriction.

dispatch: stop parsing of early boolean option at "--"

dispatch: extract stub function to peek boolean command option We should at least stop parsing at "--". The 'name' argument is passed for future extension.

dispatch: do not drop unpaired argument at _earlygetopt() Before, "hg log -R" just worked.

amend: update .hgsubstate before committing a memctx (issue5677) This is a minimal copy of localrepo.commit(). As the current amend() function heavily depends on the wctx API, it wasn't easy to port it to use a separate status tuple. So for now, wctx._status is updated in-place.

subrepo: extract preprocess of repo.commit() to free function No code change other than extracting a function. Maybe we should stop mutating the status argument, but that's out of the scope of stable changes.

tests: demonstrate that .hgsubstate isn't updated on amend Loosely based on test-amend.t and test-subrepo.t

amend: do not drop missing files (issue5732) samefile() can be wrong since wctx.manifest() does not include missing files, whereas missing files should be preserved on commit.

amend: do not take untracked files as modified or clean (issue5732) fctx.exists() shouldn't be used here as it checks if a file physically exists, which may disagree with the dirstate.
