largefiles: drop partial support for not having a user cache
971c55ce03b8 introduced support for not having a "global" user cache.
In the rare cases where the environment didn't provide the location of the
current home directory, the usercachepath function could return None.
That functionality has since bitrotten and several code paths did not correctly
check for usercachepath returning None:
$ HOME= XDG_CACHE_HOME= hg up --config extensions.largefiles=
getting changed largefiles
abort: unknown largefiles usercache location
Dropping the partial support for it is thus not really a backward compatibility
breaking change.
Thus: consistently fail early if the usercache location is unknown.
It is relevant to be able to control where the largefiles are stored and how
they propagate, but that should probably be done differently. The dysfunctional
code just gets in the way.
largefiles: refactor usercachepath - extract user cache path function
It is convenient to have the user cache location explicitly.
shelve: adds restoring newly created branch (
issue5048) (BC)
Before this patch shelve never preserved branch information,
so after applying unshelve branch was the same as it was
on working copy no matter in which branch shelve took place.
This patch makes bare shelving(with no files specified, without
interactive,include and exclude option) remembers information if
the working directory was on newly created branch ,in other words
working directory was on different branch than its first parent.
In this situation unshelving restores branch information to the working
directory.
shelve: make non bare shelve not saving branch information in bundle
This patch prepares for restoring newly created branch only on
bare shelve later because information about new-branch will be
preserved only when shelve was bare and working copy branch
was different than branch of its parent. In other case information
about new-branch will be gone, so unshelve will not recognise that
shelve was made on new-branch and it will not restore branch
information from the bundle to the working directory.
shelve: preserve newly created branch on non-bare shelve in wctx (BC)
Before this patch current branch in working context wasnt preserved
after shelve, this patch makes it restore after update.
crecord: rewrite a comment about filtering patches
I couldn't parse the previous version. I think the rewrite better
expresses the intent of that comment.
run-tests: teach _processoutput to handle multiple lines of churn
Instead of treating expected output as happening in a precise order,
and assuming that if a line is missing it will never happen,
assume that expected output is a prioritized list of likely matching
lines.
This means that if:
foo/bar (glob)
baz/bad (glob)
changes to:
baz/bad
foo/bar
instead of generating:
baz/bad
foo/bar
For which we've lost both (glob) markers,
we will match both lines and generate:
baz/bad (glob)
foo/bar (glob)
This retains any special annotations we have for lines.
run-tests: indent _processoutput to aid readability for next patch
The next commit will loop over the expected[pos] list, this change
makes that change easier to review.
