transaction-summary: show the range of new revisions upon pull/unbundle (BC) Upon pull or unbundle, we display a message with the range of new revisions fetched. This revision range could readily be used after a pull to look out what's new with 'hg log'. The algorithm takes care of filtering "obsolete" revisions that might be present in transaction's "changes" but should not be displayed to the end user.

i18n: cache translated messages per encoding This is a simpler workaround alternative to D958, "i18n: clean msgcache when encoding changes." The cache won't be bloated unless you run tons of commands with different --encoding options on command server, or serve many repositories of different web.encoding options on hgweb. The test was originally written by Jun Wu. Differential Revision: https://phab.mercurial-scm.org/D1053

templater: fix ifcontains() to handle type mismatch gracefully This was unintentionally changed in ee0d74083a22. Since ifcontains() takes needle of any types, it shouldn't abort depending on the given container type.

help: use single quotes in ``template example`` It was hard to read because ``""`` was rendered as """".

help: hide template keywords of obsolescence as they are still experimental

help: fix formatting of template keywords Our minirst formatter can't render multi-paragraph definition lists well. Also added periods where appropriate.

chg: remove outdated rule to start test server This rule is no longer useful because chg daemon may be killed and respawned per config/environment hash. We can't reliably run a daemon in foreground.

configitems: drop redundant default of web.allow<archtype> Otherwise develwarn would be sent to stderr. I've added blackbox logging to capture warnings.

configitems: correct default values of web.allow<archtype> and web.hidden The default of ui.configbool() is False unless explicitly specified.

bdiff: include compat.h in header to define ssize_t Before ff4c9c6263de, compat.h was included first so it happened to work. But we shouldn't rely on the include order.

test: add an extra case for obsolescence distributed case This changeset introduces a new documented test case for a distributed obsolescence scenario. The scenario involves a simple case where some obsolescence markers are retrieved before the changeset they affect. See the test case documentation for details. We also test variants where the changesets are added from a bundle.

test: add a test file dedicated to an important distributed case This test file introduces documented test case for obsolescence markers usage that are important to distributed workflow cases. In the distributed case, new changesets, markers, and phases can be added in orders that would not happen during the local only usage. Documenting these scenarios and test them is important as we make progress with various obsolescence aspects.

repoview: remove incorrect documentation of the function In repoview.py, computeunserved() and computemutable() functions had the same documentation. The documentation of computemutable() is wrong. I was unable to write documentation for the function but it's better to not having the documentation than having it wrong. Differential Revision: https://phab.mercurial-scm.org/D1016

check-code: suggest pycompat.is(posix|windows|darwin) Differential Revision: https://phab.mercurial-scm.org/D1037

codemod: use pycompat.isdarwin This is done by: sed -i "s/pycompat\.sysplatform == 'darwin'/pycompat.isdarwin/" **/*.py Plus a manual change to `sslutil.py` which involves indentation change that cannot be done by `sed`. Differential Revision: https://phab.mercurial-scm.org/D1035

codemod: use pycompat.isposix This is done by: sed -i "s/pycompat\.osname == 'posix'/pycompat.isposix/" **/*.py Differential Revision: https://phab.mercurial-scm.org/D1036

codemod: use pycompat.iswindows This is done by: sed -i "s/pycompat\.osname == 'nt'/pycompat.iswindows/" **/*.py sed -i "s/pycompat\.osname != 'nt'/not pycompat.iswindows/" **/*.py sed -i 's/pycompat.osname == "nt"/pycompat.iswindows/' **/*.py Differential Revision: https://phab.mercurial-scm.org/D1034

pycompat: define operating system constants As suggested by Ryan in D1019, it's cleaner if we use defined constants instead of `osname == 'nt'` everywhere. Differential Revision: https://phab.mercurial-scm.org/D1033

hgweb: do not import uuid immediately to avoid its side effect With hgdemandimport disabled (chg's case), `import uuid` has an immediate side effect calling `ctypes.util.find_library` trying to locate the `libuuid` library. This happens at `import` time before `dispatch.run()`. The call trace is like: File "hg/hg", line 54, in <module> from mercurial import ( File "hg/mercurial/dispatch.py", line 24, in <module> from . import ( File "hg/mercurial/commands.py", line 23, in <module> from . import ( File "hg/mercurial/help.py", line 33, in <module> from .hgweb import ( File "hg/mercurial/hgweb/__init__.py", line 20, in <module> from . import ( File "hg/mercurial/hgweb/hgweb_mod.py", line 14, in <module> from .common import ( File "hg/mercurial/hgweb/common.py", line 15, in <module> import uuid File "/usr/lib64/python2.7/uuid.py", line 404, in <module> lib = ctypes.CDLL(ctypes.util.find_library(libname)) The problem is, `ctypes.util.find_library` will execute `sh -c '/sbin/ldconfig -p 2>/dev/null'` on Python <= 2.7.12. The output of `sh` may pollute the terminal: shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory This patch moves `import uuid` so its side-effect can only happen after the cwd check in `dispatch._getlocal`. Therefore the terminal won't be polluted by importing `uuid`. Differential Revision: https://phab.mercurial-scm.org/D1024

selectors2: do not use platform.system() `platform.system()` may have a side effect spawning a shell executing `uname -p`, which may print a warning when the current directory is removed: shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory This patch changes selectors2 to test the `sys.platform` string, which is a much safer way to detect Jython. Jython's `sys.platform` looks like this: Jython 2.7.1 (default:0df7adb1b397, Jun 30 2017, 19:02:43) [OpenJDK 64-Bit Server VM (Oracle Corporation)] on java1.8.0_144 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.platform 'java1.8.0_144 ( ==linux2 for targets )' Differential Revision: https://phab.mercurial-scm.org/D1018

dispatch: when --pager=no is passed, also disable pager on req.repo.ui With a future chg change, `req.repo` could be set and currently it is unaffected by `--pager=on`. This patch makes it so. This could make one of the test cases in `test-pager.t` pass with future chg changes. Differential Revision: https://phab.mercurial-scm.org/D990
