When there's a single parent, we can determine if a commit is empty by
just comparing the tree ids. Also, when using tree-level conflicts, we
don't need to read the trees to determine if there's a conflict. This
patch adds both of those fast paths, speeding up `jj log -r ::main`
from 317 ms to 227 ms (-28.4%). It has much larger impact with our
cloud-based backend at Google (~5x faster).
I made the same fix in the revset engine and the Git push code (thanks
to Yuya for the suggestion).
I made it simply fail on explicit fetch/import, and ignored on implicit import.
Since the error mode is predictable and less likely to occur. I don't think it
makes sense to implement warning propagation just for this.
Closes#1690.
The way `jj git push` without arguments chooses branches pointing to
either `@` or `@-` is unusual and difficult to explain. Now that we
have `-r`, we could instead default it to `-r '@-::@'`. However, I
think it seems likely that users will want to push all local branches
leading up to `@` from the closest remote branch. That's typically
what I want. This patch changes the default to do that.
If there are branches in the revset that don't need to be pushed
because they already match the destination, we currently just print
`Nothing changed.` It seems consistent with that to also treat it as
success if there are no branches in the specified set to start
with. This patch makes the command print a warning in that case
instead.
This commit replaces the functions `UserSettings::user_name_placeholder()`` and
`UserSettings::user_email_placeholder()` with `const` `&str`s to emphasize that
the placeholder strings must not be changed to support commits without
names or email addresses made before this change.
AFAIK, we can't make HEAD detached in an empty Git repository, so we need
to temporarily switch to the new default branch before checking out.
Fixes#2047
This makes it possible to use ed25519 and ed25519-sk keys by trying
them one at a time. However, it still fails if one of them is
password-protected; we don't try the next key in that case.
Summary: In preparation for unifying all workspace dependencies across all
crates, let's go ahead and move the jj-cli crate into its own new directory.
This will also be a nicer and more uniform layout as we add new `jj-*` crates.
