hooks: add some test about HGPLAIN setting and hooks In Mercurial 5.7, hooks are now ran with HGPLAIN set, which is a behavior change in. I could not find explicit test about it so I am adding one. The next changesets will introduce more change to help user mitigate the behavior change when needed. Differential Revision: https://phab.mercurial-scm.org/D9979

hooks: forbid ':' in hook name The `:` character is a special separator in the config and it seems same do to the same for hooks. This is necessary to improve the experience around the HGPLAIN behavior change in 5.7. See next changesets for details. Differential Revision: https://phab.mercurial-scm.org/D9978

tweak-default: no longer enable the experimental return code The change is quite new and undocumented (since it is experimental) so it seems premature to make it available in tweak default. In addition, I am not sure the new return code are frozen yet (eg: some of the initial feedback have not been incorporated). Before the release I doubled check (probably with Martin) that they were not enabled by default and got replied that they were only enabled in the tests. Have I been aware that they have been also enabled in tweak default I would I have lobbied to delay that. I discovered they were in tweak default from users feedback. They found it an unpleasant and unexpected surprise of 5.7. So I suggest we no enable enable this experimental feature for Mercurial 5.7 and revisit this later, when the feature will be more mature.

cmdutil: add a missing byte prefix to string introduce in 976b26bdd0d8 The change is missing a the `b'foo'` prefix to make it a bytestring. This lead to a traceback in some third party extension. It is unclear to me why the Mercurial test pass without it. Differential Revision: https://phab.mercurial-scm.org/D9974

relnote: remove the reference to `debugstrip` The `debug` namespace is not intended for end user and advertising it is a path to confusion and trouble. I think we should wait for the `admin` namespace to exists and the command to be available as `admin--strip` before we advertise it. Differential Revision: https://phab.mercurial-scm.org/D9817

largefiles: properly pass kwargs into url.open The url.open function has acquired a lot of kwargs over the years. When running `hg import http://example.com/hg/diff/1`, since at least a708e1e4d7a8 in March, 2018, the calling sites for url.open try to pass a `sendaccept` parameter that largefiles' override doesn't accept. Currently that stack traces something like this: Traceback (most recent call last): File "/tmp/hgtests.sv744r5t/install/bin/hg", line 59, in <module> dispatch.run() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 143, in run status = dispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 245, in dispatch status = _rundispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 289, in _rundispatch ret = _runcatch(req) or 0 File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 465, in _runcatch return _callcatch(ui, _runcatchfunc) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 475, in _callcatch return scmutil.callcatch(ui, func) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/scmutil.py", line 155, in callcatch return func() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 455, in _runcatchfunc return _dispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1259, in _dispatch lui, repo, cmd, fullargs, ui, options, d, cmdpats, cmdoptions File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 913, in runcommand ret = _runcommand(ui, options, cmd, d) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1270, in _runcommand return cmdfunc() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1256, in <lambda> d = lambda: util.checksignature(func)(ui, *args, **strcmdopt) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/util.py", line 1867, in check return func(*args, **kwargs) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/commands.py", line 4184, in import_ patchfile = hg.openpath(ui, patchurl, sendaccept=False) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/hg.py", line 181, in openpath return url.open(ui, path, sendaccept=sendaccept) TypeError: openlargefile() got an unexpected keyword argument 'sendaccept' So, just accept and pass along any kwargs of the overridden function.

wix: tell ComponentSearch that it is finding a directory (not a file) This is to fix an issue we've noticed where fresh installations start at `C:\Program Files\Mercurial`, and then upgrades "walk up" the tree and end up in `C:\Program Files` and finally `C:\` (where they stay). ComponentSearch defaults to finding files, which I think means "it produces a string like `C:\Program Files\Mercurial`", whereas with the type being explicitly a directory, it would return `C:\Program Files\Mercurial\` (note the final trailing backslash). Presumably, a latter step then tries to turn that file name into a proper directory, by removing everything after the last `\`. This could likely also be fixed by actually searching for the component for hg.exe itself. That seemed a lot more complicated, as the GUID for hg.exe isn't known in this file (it's one of the "auto-derived" ones). We could also consider adding a Condition that I think could check the Property and ensure it's either empty or ends in a trailing slash, but that would be an installer runtime check and I'm not convinced it'd actually be useful. This will *not* cause existing installations that are in one of the bad directories to fix themselves. Doing that would require a fair amount more understanding of wix and windows installer than I have, and it *probably* wouldn't be possible to be 100% correct about it either (there's nothing preventing a user from intentionally installing it in C:\, though I don't know why they would do so). If someone wants to tackle fixing existing installations, I think that the first installation is actually the only one that shows up in "Add or Remove Programs", and that its registry keys still exist. You might be able to find something under HKEY_USERS that lists both the "good" and the "bad" InstallDirs. Mine was under `HKEY_USERS\S-1-5-18\Software\Mercurial\InstallDir` (C:\), and `HKEY_USERS\S-1-5-21-..numbers..\Software\Mercurial\InstallDir` (C:\Program Files\Mercurial). If you find exactly two, with one being the default path, and the other being a prefix of it, the user almost certainly hit this bug :D We had originally thought that this bug might be due to unattended installations/upgrades, but I no longer think that's the case. We were able to reproduce the issue by uninstalling all copies of Mercurial I could find, installing one version (it chose the correct location), and then starting the installer for a different version (higher or lower didn't matter). I did not need to deal with an unattended or headless installation/upgrade to trigger the issue, but it's possible that my system was "primed" for this bug to happen because of a previous unattended installation/upgrade.

share: rename share-safe warning config Config introduced in previous patch was `share.source-safe-mismatch`. Let's rename the warn as `share.source-safe-mismatch.warn`. While we are here, made sure we have different configs for upgrade and downgrade. Differential Revision: https://phab.mercurial-scm.org/D9786

share: rework config options to be much clearer and easier Recently I implemented various boolean configs which control how to behave when there is a share-safe mismatch between source and share repository. Mismatch means that source supports share-safe where as share does not or vice versa. However, while discussion and documentation we realized that it's too complicated and there are some combinations of values which makes no sense. We decided to introduce a config option with 4 possible values which makes controlling and understanding things easier. The config option `share.safe-mismatch.source-{not-}safe` can have following 4 values: * abort (default): error out if there is mismatch * allow: allow to work with respecting share source configuration * {up|down}grade-abort: try to {up|down}grade, if it fails, abort * {up|down}grade-allow: try to {up|down}grade, if it fails, continue in allow mode I am not sure if I can explain 3 config options which I deleted right now in just 5 lines which is a sign of how complex they became. No test changes demonstrate that functionality is same, only names have changed. Differential Revision: https://phab.mercurial-scm.org/D9785

localrepo: disallow share if there is a version mismatch by default Earlier we used to allow shares which don't use share-safe mechanism to access repository which uses share-safe mechanism.

run-tests: catch a Windows specific error when testing for a free socket I'm not sure why this only happens with py3, but this error code doesn't map to any of the 3 currently being handled, and kills `run-tests.py` before it can run any tests when it happens: OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions The documentation[1] says this can happen if another process is bound to the address with exclusive access.

run-tests: work around the Windows firewall popup for server processes Windows doesn't have a `python3` executable, so cc0b332ab9fc attempted to work around the issue by copying the current python to `python3.exe`. That put it in `_tmpbindir` because of failures in `test-run-tests.t` when using `_bindir`, which looked like a process was trying to open it to write out a copy while it was in use. (Interestingly, I couldn't reproduce this running the test by itself in a loop for a couple of hours, but it happens constantly when running all tests.) The problem with using `_tmpbindir` is that it is the randomly generated path for the test run, and instead of Windows Firewall remembering the executable signature or image hash when allowing the process to open a server port, it apparently remembers the image path. That means every run will trigger a popup to allow it, which is bad for firing off a test run and walking away. I tried to symlink to the python executable, but that currently requires admin priviledges[1]. This will prompt the first time if the underlying python binary has never opened a server port, but appears to avoid it on subsequent runs.

hghave: split apart testing for the curses module and `tic` executable ef771d329961 skipped the check for the `tic` executable, because the curses module alone on Windows is enough to pass the `test-*-curses.t` tests. However, `test-status-color.t` uses this same check and explicitly invoked the executable, which fails on Windows. From the cursory searching I did, curses on unix requires `tic`, which I assume is why they were tied together in the first place. So this continues to require both to get past the curses guards on non Windows platforms. Differential Revision: https://phab.mercurial-scm.org/D9814

windows: wrap `os.getcwd()` in `os.path.realpath()` on py3 I noticed various `test-check-*` failures that were printing absolute paths when repo relative paths were expected. This was due to the drive letter in `repo.root` being uppercased as it is run through `os.path.realpath()`, and then the simple string comparison against the (lowercased) `_cwd` member of dirstate in `dirstate.getcwd()` causing an absolute path to be returned, instead of the expected `b''`.

clone: make sure we warm the cache after a clone This work around any deviciency/limitation of the clone process. In our case this ensure the persistent nodemap exist with valid content. Ideally, the cloning process would also do "the right thing". However since older server will never be able to do "the right thing". The local workaround will be necessary anyway. I am not worried by the performance impact of this as `hg clone` is non-instant on large repositories where is could matters. Warming the cache if they are already correct is very fast. And if they are not already warm, this seems like a good time to do so. This impact various test as more cache are now warmed sooner, all the change should be harmless.
