lfs: restore the local blob store after a repo upgrade This also ends up testing the local extension wrapping for dstrepo during upgrade, which was fixed in 06987c6971be.

lfs: override walk() in lfsvfs In order to fix the missing lfs store after an upgrade, I attempted to walk the store vfs to hardlink to the upgraded repo's store. But the custom join() clashes with the default walk() implementation. First, 'path=None' blew up in the regex matcher, because it wanted a string. But even if that is fixed, the join to walk the root of the vfs wouldn't match the required xx/xx...xx pattern. The first cut of this was a copy/paste/tweak of the base implementation, but this version of walk() hides the internal directories, and treats the vfs as a flat store. I think this makes sense because most vfs methods call join() on input paths, which wants the simple oid format. It also relieves the caller from having to deal with bogus files/directories in the store.

tests: add coverage for preserving 'lfs' requirement on repo upgrade The test also shows that the local blob store is erroneously lost.

py3: handle keyword arguments correctly in hgext/largefiles/ Keys of keyword arguments must be str(unicode) on Python 3. The transformer which we use on Python 3, appends b'' in front of each string literal, so this may lead in KeyError or None return even when the key is present by we are using bytes value and it's stored in unicodes. This patch and all the similar patches handle this by either converting the keys of kwargs to bytes using 'pycompat.byteskwargs()' or adding r'' so that the transformer won't append b''. This next 23 patches follows the above mentioned way to handle keyword arguments. Differential Revision: https://phab.mercurial-scm.org/D1624

remotenames: rename related file and storage dir to logexchange This patch renames remotenames.py to logexchange.py, test-remotenames.t to test-logexchange.t. Also this patch renames the directory in which the data is stored from remotenames to logexchange. After this patch, data about bookmarks and branches from a server we pull is stored in `.hg/logexchange/(bookmarks|branches)` files. Thanks to smf for the suggestion.

lfs: allow to run 'debugupgraderepo' on repo with largefiles The extensions wrap the necessary function to ensure the 'lfs' requirements won't be dropped. It is now possible to run `hg debugupgraderepo` on a repository with lfs.

upgrade: add a 'redeltafullall' mode We add a new mode for delta recomputation, when selected, each full text will go through the full "addrevision" mechanism again. This is slower than "redeltaall" but this gives the opportunity for extensions to trigger special logic. For example, the lfs extensions can decide to promote some revision to lfs storage during the upgrade.

upgrade: use actual filelog to convert filelog Extensions can add extra logic related to the config, so we must use the actual class. The path used needs minimal transformation for this to work.

upgrade: more standard creation of the temporary repository By using the standard path to create a repository we fill some hole in the current initialization process. The one who triggered this changeset was the lack of extensions initialization.

upgrade: use the repository 'ui' as the base for the new repository The `repo.baseui` contains all the configuration but the one specific to the repository (so it can be used when dealing with local peer and sub- repository). However, we need the repository config to be taken into account when doing the upgrade. Otherwise, the upgrade related config that exists in the repository config won't be taken into account when performing the update. A buggy and surprising behavior. We had to work around protection set around `repo.ui.copy` since we are an uncommon case.

upgrade: add a test to show the repository config being ignored The upgrade process ignores the config within the repository. The next changeset fixes it, but we introduce this test before to show it actually tests our target.

upgrade: register compression as a format variants Compression is a promising vector for speedup, let us make it easier to check the compression used and upgrade existing repository.

debugformat: handle non-boolean value for variant

debugformat: update label depending on value difference The new label highlight areas where the repo format differs from current config or default. This should help people spot area where a repository mismatch with the expected state.

debugformat: add data about the config when verbose In verbose mode, the command also displays the current configuration choice for the variant and the global Mercurial default for it.
