color: respect HGPLAINEXCEPT=color to allow colors while scripting (issue5749) I'd also like --color=always on the command-line to override HGPLAIN=1 et al, but that's more work, and this seems like a better fix. We've got a fair number of programs that actually want to automate hg and get colored output to users, so they should set HGPLAINEXCEPT=alias (what we usually recommend), but this has been breaking them because they then lose color. .. feature:: The ``HGPLAINEXCEPT`` environment variable can now include ``color`` to allow automatic output colorization in otherwise automated environments.

test-ssh: do not actually look up "brokenrepository" by DNS

largefiles: explicitly set the source and sink types to 'hg' for lfconvert I stumbled into this prior to adding the type indicator on the source and sink, but there's no reason to try to infer the types for this conversion.

lfs: add a repo requirement for this extension when converting to lfs This covers both the vanilla repo -> lfs repo and largefiles -> lfs conversions. The largefiles extension adds the requirement directly, because it has a dedicated command to convert. Using the convert extension is better, because it supports more features. I'd like ideas about how to ensure that converting away from lfs works on all files. (See comments in test-lfs.t)

convert: allow the sink object to be wrapped when the extension isn't loaded The next patch will wrap the conversion code, in order to write out a requirement for 'lfs' when appropriate. Wrapping convcmd.convertsink() in an afterloaded callback works fine when the convert extension is enabled by the user. The problem here is that lfconvert uses the convert extension, whether or not it was formally enabled by the user. My first attempt was to have lfs install an afterloaded callback that would wrap the convert sink if convert was loaded, or wrap lfconvert if it wasn't. Then the lfconvert override could install an afterloaded callback to try wrapping the convert sink again, before calling the original lfconvert. But that breaks down if largefiles can't load the convert extension on the fly. [1] Further, some tests were failing with an error indicating that the size of the afterloaded list changed while iterating it. Yuya mentioned that maybe some bits of convert could be moved into core, but I'm not sure where to draw that line. The convertsink() method depends on the list of sinks, which in turn depends on the sink classes. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-November/108038.html

convert: save an indicator of the repo type for sources and sinks This seems like basic info to have, and will be used shortly when deciding whether or not to wrap the class for lfs conversions. The other option is to just add a function to each class. But this seems better in that the strings aren't duplicated, and the constructor for most of these will run even if the VCS isn't installed, so it's easier to catch errors.

lfs: add a repo requirement for this extension once an lfs file is committed Largefiles does the same thing (also delayed until the first largefile commit), to prevent access to the repo without the extension. In the case of this extension, not having the extension loaded while accessing an lfs file results in cryptic errors about "missing processor for flag '0x2000'". If enabled locally but not remotely, the cryptic error message is about no common changegroup version. (It wants '03', which is currently experimental.) The largefiles extension looks for any tracked file that starts with '.hglf/'. Unfortunately, that doesn't work here. I didn't see any way to get the files that were just committed, without doing a full status. But since there's no secondary check on adding an lfs file once the extension is loaded and a threshold set, the best practice is to only enable this locally on a repo that needs it. That should minimize the unnecessary overhead for repos without an lfs file.

merge: check created file dirs for path conflicts only once (issue5716) In large repositories, updates involving the creation of many files check the same directories repeatedly in the wctx manifest. Move these checks out to a separate loop to avoid repeated checks hitting the manifest. Differential Revision: https://phab.mercurial-scm.org/D1226
