It's reasonable for a `WorkingCopy` implementation to want to return
an error. `LocalWorkingCopyFactory` doesn't because it loads all data
lazily. The VFS-based one at Google wants to be able to return an
error, however.
This one just tests with a larger value and a human-readable string (10KB).

For new users this results in a significantly better error output, that
actually shows them how to solve the problem, and why it happened.

Previously, this command would work:
jj --config-toml='snapshot.max-new-file-size="1"' st
And is equivalent to this:
jj --config-toml='snapshot.max-new-file-size="1B"' st
But this would not work, despite looking like it should:
jj --config-toml='snapshot.max-new-file-size=1' st
This is extremely confusing for users.
This config value is deserialized via serde; and while the `HumanByteSize`
struct allegedly implemented Serde's `visit_u64` method, it was not called by
the deserialize visitor. Strangely, adding an `visit_i64` method *did* work, but
then requires handling of overflow, etc. This is likely because TOML integers
are naturally specified in `i64`.
Instead, just don't bother with any of that; implement a `TryFrom<String>`
instance for `HumanByteSize` that uses `u64::from_str` to try parsing the string
immediately; *then* fall back to `parse_human_byte_size` if that doesn't work.
This not only fixes the behavior but, IMO, is much simpler to reason about; we
get our `Deserialize` instance for free from the `TryFrom` instance.
Finally, this adjusts the test for `max-new-file-size` to now use a raw integer
literal, to ensure it doesn't regress. (There are already in-crate tests for
parsing the human readable strings.)

This replaces `.map(|c| c.id().clone())` with `.ids().cloned()` to use nicer
syntax for getting `CommitId`s from an iterator of commits using the
`CommitIteratorExt` trait.
In one case we can actually call `.parent_ids()` directly. I also pluralized a
variable to make it clearer that it's a vec of IDs and not a single ID.
The rewritten code is already a no-op when there's a single input. I
don't think the case is common enough to warrant having a special case
for performance reasons either. Also, by not having the special case,
`jj parallelize <immutable commit>` fails consistently with the
non-singleton case.
I'm going to make some `jj parallelize` cases that currently error out
instead be successful. Some of the will result in ancestor merges with
the root commit. This patch updates those tests to avoid that.
`jj parallelize` was a good example of a command that can be
simplified by the new API, so I decided to rewrite it as an example.
The rewritten version is more flexible and doesn't actually need the
restrictions from the old version (such as checking that the commits
are connected). I still left the check for now to keep this patch
somewhat small. A subsequent commit will remove the restrictions.
`CommitRewriter` wraps 3 of the arguments, so I think it makes sense
to pass it instead. More importantly, I hope to continue refactoring
so many of the callers already have a `CommitRewriter`.
It was removed at 522025e091 "log: remove unused and inconsistent `log`
label", but obslog had the same inconsistency. Since it's now easy to label
the template output, let's re-add the "log" label.
The change in test_templater_upper_lower() is noop. Formatter no longer
emits reset sequence in the middle because the template is still labeled.
These labels could be renamed to "log_node"/"op_log_node" for consistency, but
I'm not sure if that's a good idea. A single "node" namespace is practically
more convenient.
It's not uncommon to label the whole template output with command or template
name. If the output doesn't have to be captured, we can simply push the label
to the formatter. cmd_config_list() is an example of such cases, but it's also
migrated for consistency.
Mercurial appears to resolve cwd-relative path first, so "glob:*.c" could be
parsed as "**/*.c" if cwd was literally "**". It wouldn't practically matter,
but isn't correct. Instead, jj's parser first splits glob into literal part
and pattern. That's mainly because we want to parse the user input texts into
type-safe objects, and (RepoPathBuf, glob::Pattern) pairs are the simplest
ones. The current parser can't handle patterns like "foo/*/.." (= "foo" ?),
and errors out. I believe this restriction is acceptable.
Unlike literal paths, the 'glob:' pattern anchors to the whole file path. I
don't think "prefix"-matching glob is useful, and making it the default would
be rather confusing.
It's cheap to look up commits again from the cache in `Store` but it
can be expensive to look up commits we didn't end up needing. This
will make it easier to refactor further and be able to cheaply set
preliminary parents for a rewritten commits and then let the caller
update them.
I'm going to add a helper struct to help with rewriting commits. I
want to make that struct own the old commit and the new parents to
simplify lifetimes. This patch prepares for that by passing the
commits by value to `rebase_commit()`.
Running `cargo publish` from a non-colocated repo (such as my usual
repo) is currently quite scary because it uploads all non-hidden
files, even if they're ignored by `.gitignore`
(https://github.com/rust-lang/cargo/issues/2063). I noticed this a
while ago and have always run the command from a fresh clone since
then. To avoid the need for that, let's use the workaround mentioned
on the bug, which is to explicitly list patterns we want to publish.
This fixes several issues that made working with empty files difficult using
the builtin diff editor.
1. The scm-record library used for the editor expects each file to have at
least one section. For new empty files this should be a file mode section. jj
wasn't rendering this mode section, which prevented empty files from being
selected at all.
2. The scm-record library returns `SelectedContents::Absent` if the file has no
contents after the diff editor is invoked. This can be because of several
reasons: 1) the file is new and empty; 2) the file was empty before and is
still empty; 3) the file has been deleted. Perhaps this is a bug in scm-record
and it should return `SelectedContents::Unchanged` or
`SelectedContents::Present` if the file hasn't been deleted. Until this is
patched upstream, we can work around it by disambiguating these cases.
See https://github.com/arxanas/scm-record/issues/26 for the upstream bug.
Fixes#3016
This is the last non-debug command that doesn't support file patterns. It
wouldn't make much sense to "cat" multiple files (despite the command name),
but doing that should be harmless.
Prepares for migrating to the matcher API. "Path exists but is not a file"
error is turned into a warning because the loop shouldn't terminate there.
"No such path" error message is also updated for consistency.
if `--use-destination-message/-u` is passed to `jj squash`, the resulting
revision will use the description of the destination revision and the
description(s) of the source revision(s) will be discarded.
If we ever implement some sort of ABI for dynamic extension loading, we'll need these underlying APIs to support multiple extensions, so we might as well do that first.
If this doesn't work out, maybe we can try one of these:
a. fall back to bare file name if expression doesn't contain any operator-like
characters (e.g. "f(x" is an error, but "f x" can be parsed as bare string)
b. introduce command-line flag to opt in (e.g. -e FILESET)
c. introduce pattern prefix to opt in (e.g. set:FILESET)
Closes#3239, #2915, #2286
This is the same as the `test_split_siblings_with_merge_child` added in
https://github.com/martinvonz/jj/pull/3485, but without the siblings flag. I
forgot to add the non-siblings version in that PR.

This command checks not only whether Watchman works, but also whether
it's enabled in the config. Also, the output is easier to understand
than that of the other `jj debug watchman` commands.
It would be nice if `jj debug watchman` called `jj debug watchman
status`, but it's not trivial in `clap` to have a default subcommand.
Ilya reported this in https://github.com/martinvonz/jj/issues/3483.
The bug was introduced in 976320726d.
Before this fix, `jj split` dropped any parents what weren't involved in the
split when it rebased the children of the commit being split. This meant that
any children which were merge commits lost their other parents unintentionally.
Fixes#3483
Maybe we can optimize it to check paths during diffing, but I think it's okay
to add extra lookup cost at the end. The size of the path arguments is usually
small.
Closes#505
Path parsing will be migrated to parse_union_filesets(), but I haven't decided
how we'll go forward:
a. migrate everything to fileset
b. require flag like "-e FILESET" (note -p conflicts with log -p)
c. require flag like "-e FILESET" and deprecate positional PATHs #2554
d. require prefix like "set:FILESET" (not consistent with -r REVSET)
I'm currently dogfooding (a). It works for me, but I don't use exotic file
names that would require quoting in zsh.
#3239
Before this commit `jj prev` fails if the current working copy commit is a
merge commit. After this commit it will prompt the user to choose the ancestor
they want to select.
#2126
This commit adds commit graphs to most of the tests for `jj prev` to make it
clearer where `@` points before and after `prev` is run.
In addition, there were a couple of tests where the comments suggested the test
meant to have `@` pointing to a specific commit, but it actually pointed to an
empty child of that commit.
This sort of issue also exists in `test_prev_editing`. The test is supposed to
check that `--edit` is implied if you run `jj prev` on an interior commit, but
it actually caused a new empty commit to be created since `@` was sitting on a
tip commit.
Expose the information we now record, to allow changing the default "snapshot
working copy" message or to make snapshots more compact/less distracting in
the log
This will hopefully make it clear that `jj prev` does not
move by [OFFSET] relative to `@`, which is a misconception
that I had and I think others may also have.
I am suggesting this change as a result of the vigorous discussion in
these two issues:
- https://github.com/martinvonz/jj/issues/3426
- https://github.com/martinvonz/jj/pull/3445
We should make similar changes to `jj next` as well since
it follows similar rules.
