fix: highlight the required configuration and behavior of the fixer tools
The problem is that `hg help fix` didn't mention *how* to configure the tools,
and while I knew that `{rootpath}` existed in the configuration, I missed that
the tools require reading content from stdin. (I configured `gofmt` to use
`{rootpath}`, and that had the effect of squashing all changes in a file at `.`
into the first commit and emptying that content from its descendants.)
Basically all this does is put a pointer in the default (command level) help to
the extension level help that mentions the configuration, and moves the
extension level help that documents reading from stdin and writing to stdout to
the top to give it more prominence. The last sentence is adjusted a bit to
reflect the new location.
debug-delta: add minimal documentation for `devel.bundle-delta` option
So the next person won't have to grep the code to know what it is doing.
delta-find: simply code that is now never invoqued without general delta
Finish early in on-general delta case mean a lot of code can assume that general delta is not enabled.
delta-find: add a simple safeguard to prevent bad non-general-delta
This make it easier to catch request to build delta that does not make sense in
the general delta world.
It seems better to raise a programming error than to corrupt the repository.
delta-find: never do anything fancy when general delta is off
Without general delta, the only option is to do a delta against the previous
revision in the revlog, or to do a full snapshot. So no need to dive into the
more complicated logic.
This prevent Mercurial to misbehave when applying remote deltas when
`pulled-delta-reuse-policy` was set to "try-base" or "forced" and would produce
and store invalid deltas.
We add an associated tests to make sure this scenario is covered by tests.
There are more code to cleanup after this, but I what to keep the fixing patch
simple.
delta-find: assume the target-rev if not specified
This will be useful in the next patch, but I am putting it in its own commit to
make sure we can easily bisect any subtle side effect. (none are expected, but
still)
chg: set CHGHG before connecting to command server
cf4d2f31 (!523) changed chg to set `CHGHG` itself when spawning a new command
server, in order to ensure that the path to the `hg` executable would be checked
during server validation. (This is useful when chg is built with `HGPATHREL`).
However, that change broke chg because it failed to set `CHGHG` before trying
to connect to an existing command server. This means that if `CHGHG` is not
present in the environment, chg will always spawn a new command server, entirely
negating the point of chg.
This breakage wasn't initially caught because of the difficulty of writing
automated tests with the `HGPATHREL` feature enabled, which meant the change
was only tested manually to make sure that it fixed the problem with `HGPATHREL`
that prompted the change.
In practice, this functionality is only really useful when chg is built with
`HGPATHREL`, so I considered wrapping it in an `#ifdef` to preserve the old
behavior by default. However, this makes it hard to write tests since one would
have to explicitly set `HGPATHREL=1` when running `run-tests.py` (which is why
the original change lacked tests). It would be great if there were a way of
testing features that are gated behind conditional compilation.

revlog-split: make sure the self._indexfile attribut is reset (
issue6811)
Before this change, after a transaction committing a file split, a revlog
object would have its `self._indexfile` attribute desynchronised from the
actual file storing the data. If that same object is reused (as we do for the
manifest during clone bundles), this lead to the data being writting in the
wrong location and the repository to go corrupt.
We not properly reset the attribut when applicable and everything is back in
working order.
