The Protobuf team at Google decided to let us use Protobufs internally
after all. That will make things a little easier for us with the
Google-internal adapations, and the `protobuf` crate is noticeably
faster than the `thrift` crate.
This effectively rolls back commit 5b10c9aa0a. I resolved some
conflicts caused by the rename from `NormalFile` to `File`. I also
kept the changelog entry, but I changed it to say that the hashing
scheme has changed (not the format), but since the hashes are just
used for identity, existing repos should still work.
It should be more reliable than parsing a command string into array.
Also updated some of the doc example to use array syntax. I don't think
"C:/Program Files" was parsed properly, but might work thanks to Windows
magic.
It implements Deserialize because config.get() requires that. We could instead
add TryFrom<config::Value>, but we'll need Deserialize anyway if we want to
parse a struct containing FullCommandArgs.
I don't know if src/config.rs is the right place, but I feel it's slightly
better than messing up ui.rs.
It seems that we didn't have a test for this simple case. I wrote this
test case while working on #111 but I don't know why I didn't push it
back then.
A new FileType, GitSubmodule is added which is ignored. Files or
directories having this type are not added to the work queue and
are ignored in snapshot. Submodules are not created by jujutsu
when resetting or checking out a tree, they should be currently
managed using git.
The example for the `-b` flag was completely incorrect. It looks like
I have copied the example from `-r` and then forgotten to update
it. This fixes that, and also adds some more commits to the example to
hopefully clarify.
Teach Ui's writing functions to write to a pager without touching the
process's file descriptors. This is done by introducing UiOutput::Paged,
which spawns a pager that Ui's functions can write to.
The pager program can be chosen via `ui.pager`. (defaults to Defaults to
$PAGER, and 'less' if that is unset (falling back to 'less' also makes
the tests pass).
Currently, commands are paginated if:
- they have "long" output (as defined by jj developers)
- jj is invoked in a terminal
The next commit will allow pagination to be turned off via a CLI option.
More complex pagination toggling (e.g. showing a pager even if the
output doesn't look like a terminal, using a pager for shorter ouput) is
left for a future PR.
We'll add a variant that isn't a pair. Also add a function to create a
new UiOutput::Terminal, we will create this variant in a few places
because we want to fall back to it.
Writing double negates is silly, but it might be hidden by revset alias
if we added such feature.
I made fold_redundant_expression() a separate step from fold_difference()
since I'll probably want to apply the cleanup step before rewriting filter
expressions.
Because a unary negation node '~y' is more primitive than the corresponding
difference node 'x~y', '~y' is easier to deal with while rewriting the tree.
That's the main reason to add RevsetExpression::NotIn node.
As we have a NotIn node, it makes sense to add an operator for that. This
patch reuses '~' token, which I feel intuitive since the other set operators
looks like bitwise ops. Another option is '!'.
The unary '~' operator has the highest precedence among the set operators,
but they are lower than the ranges. This might be counter intuitive, but
useful because a prefix range ':x' can be negated without parens.
Maybe we can remove the redundant infix operator 'x ~ y', but it isn't
decided yet.
Thanks, everyone! :) I'm happy to rephrase the text. I included people
in order of their first contribution in the release. I included their
full name and the GitHub username.
I can't see any reason the user would want to specify revisions
matching the empty string, so let's disallow it. I created a custom
type for revision arguments instead of repeating `value_parser =
NonEmptyStringValueParser::new()`.
If the user creates a branch with an empty name, it seems very likely
to be an accident. Let's help them realize that by erroring out.
I didn't add the same checks to `jj branch delete`, since that would
make it hard to delete a branch with an empty name from existing
repos.
Function parameters are processed as local symbols while substituting
alias expression. This isn't as efficient as Mercurial which caches
a tree of fully-expanded function template, but that wouldn't matter in
practice.
Let's acknowledge everyone's contributions by replacing "Google LLC"
in the copyright header by "The Jujutsu Authors". If I understand
correctly, it won't have any legal effect, but maybe it still helps
reduce concerns from contributors (though I haven't heard any
concerns).
Google employees can read about Google's policy at
go/releasing/contributions#copyright.
Follows up c5ed3e1477. Now change/commit ids are resolved at the same
precedence, which means there are at least three types of ambiguity.
I don't think we would need to discriminate these.
Because the use of the change id is recommended, any operation should abort
if a valid change id happens to match a commit id. We still try the commit
id lookup first as the change id lookup is more costly.
Ambiguous change/commit id is reported as AmbiguousCommitIdPrefix for now.
Maybe we can merge AmbiguousCommit/ChangeIdPrefix errors into one?
Closes#799
84b924946f switched to requiring both
SSH_AUTH_SOCK and SSH_AGENT_PID for an agent to be used. This doesn't
seem to be a typical situation, so perhaps it was not intended.
Aliases are loaded at WorkspaceCommandHelper::new() as it's easier to warn
invalid declarations there. Not all commands use revsets, but many do, so
I think it's okay to always pay the loading cost. Parsing the declaration
part (i.e. a symbol) should be fast anyway.
The nested error message isn't super readable, but seems good enough.
Config syntax to bikeshed:
- naming: [revset-alias] vs [revset-aliases] ?
- function alias will need quotes: 'f(x)' = 'x'
Since syntactic information like symbol or function name is lost after
parse(), alias substitution is inserted to the middle of the post-parsing
stage, not after the whole RevsetExpression tree is built. This is the main
difference from Mercurial. Mercurial also caches parsed aliases, but I don't
think that would have a measurable impact.
The CLI will load aliases from config, insert them one by one, and warn if
declaration part is invalid. That's why RevsetAliasesMap is a public struct
and needs to be instantiated by the caller.
I'll add aliases map, substitution stack (to detect recursion), and locals
(for function aliases) there. Fortunately, we can avoid shared mutables
so a copyable struct should be good.
parse_function_argument_to_string() doesn't need a workspace_ctx, but there
should be no reason to explicitly nullify it either.
