py3: use system strings in HTTP server code Previously the source transformer was converting some string literals to bytes and we were comparing a system native string to bytes and this was leading to sending the wrong HTTP response headers on Python 3. After this change, we now properly send Transfer-Encoding and Connection response headers on Python 3. Differential Revision: https://phab.mercurial-scm.org/D4833

py3: byteify test-storage.py The test now passed on Python 3. # skip-blame just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D4836

narrow: remove narrowpatch instead of narrowcopies 84092edd5c88 removed narrowpatch.py and wanted to drop narrowpatch from __init__.py but mistakenly removed narrowcopies. This will make buildbots green again. Differential Revision: https://phab.mercurial-scm.org/D4837

py3: suppress the output from .write() calls in more tests I missed these in 803b7569c9ea because I forgot about `...` lines.

py3: byteify test-lfs.t

lfs: explicitly name a key when sorting blob pointers This is needed to keep py3 happy. The other two instances of sorting already did this.

py3: byteify test-lock.py There's still a stacktrace about not being able to serialize _io.TextIOWrapper.

py3: byteify contrib/dumprevlog

py3: quote $PYTHON in test-merge-symlinks.t

copies: inline a variable that's used only once By inlining it, we also avoid calculating the value when "if of in seen" is false (probably not significant). Differential Revision: https://phab.mercurial-scm.org/D4831

bundlerepo: remove a variable alias "parentrepo" and "repo" were the same thing and I don't see much reason for it (unionrepo has similar structure and a similar alias but there are two repos there so at least it makes a little more sense there).

merge with stable

Added signature for changeset 5405cb1a7901

Added tag 4.7.2 for changeset 5405cb1a7901

manifest: fix out-of-bounds read of corrupted manifest entry Spotted by ASAN.

manifest: rewrite pathlen() to not cross entry boundary Even though the entire manifest data should be terminated by '\0', it seems not nice to scan '\0' over the entry terminator, '\n'.

narrow: move support for `hg verify` into core Differential Revision: https://phab.mercurial-scm.org/D4824

narrow: drop unnecessary overrides of patch The patch overrides became unnecessary when I made context.status() filter by the narrowspec in e411774a2e0f (narrow: move status-filtering to core and to ctx, 2018-08-02). Differential Revision: https://phab.mercurial-scm.org/D4823

tests: add test showing that paths outside narrowspec are not added We had a test that shows that trying to explicitly add a file outside the narrowspec results in an error, but we didn't have a test that shows that paths from subdirectories outside the narrowspec are not added (on e.g. `hg add .`) but silently ignored.

catapipe: fix bug introduced when switching to the timer api Differential Revision: https://phab.mercurial-scm.org/D4818

narrow: move the ellipses server capability to core This will be used in core logic to determining whether a server is ellipses enabled or not. And also this will ease moving narrow related things to core. Differential Revision: https://phab.mercurial-scm.org/D4809

narrow: move the wireprotocol narrow capability name to core We are trying to integrate the whole of narrow logic into core and it will be helpful for upcoming patches to have these capability names in core. The next patch will move the ellipses capability to core also. The exact motivation is to know whether we are cloning a ellipses repo or not and adding an ellipses repo requirement.

help: document about "files" template keywords

formatter: remove experimental marker from -T option I think it's good enough to stabilize the feature, at least for the core and non-experimental commands.

grep: rename {line_number} to {lineno} as well (BC)

annotate: rename {line_number} to {lineno} (BC) I think {lineno} looks more like a common template keyword. It isn't called a {line} to avoid conflicts with the element name of {lines} and the {_|splitlines} filter. https://www.mercurial-scm.org/wiki/GenericTemplatingPlan#Dictionary

resolve: rename {status} to {mergestatus} to not shadow change status (BC) This is a part of the name unification. I think it's somewhat useful to provide a combined view of change/merge statuses. https://www.mercurial-scm.org/wiki/GenericTemplatingPlan#Dictionary

py3: whitelist one additional test Differential Revision: https://phab.mercurial-scm.org/D4817

logtoprocess: connect all fds to /dev/null to avoid bad interaction with pager We detected that pager is waiting for log-to-process script to finish, which is annoying when adding a script on commandfinish that does an HTTP push. There seems to be no workaround on the script side and it will make the behavior on Linux/MacOS closer to the Windows behavior. The drawback is that it makes the related tests more flaky as log-to-process outputs are now really asynchronous. If it's considered a BC change, another option would be to add a config option for this new behavior. I personally think that the different behavior between Windows and Linux is confusing and that it's a bug I would be fine with a new config option.

logtoprocess: add a test to show pager and ltp bad interaction The next changeset will fix the bad interaction between the pager and log-to- process. Add a test first to make the next changeset easier to understand. Differential Revision: https://phab.mercurial-scm.org/D4815
