"""a small (hacky) context to deal with lazy opening of context
This is to be used in the `commit` function right below. This deals with
lazily open a `changing_files` context inside a `transaction` that span the
full commit operation.
We need :
- a `changing_files` context to wrap the dirstate change within the
"addremove" operation,
- a transaction to make sure these change are not written right after the
addremove, but when the commit operation succeed.
However it get complicated because:
- opening a transaction "this early" shuffle hooks order, especially the
`precommit` one happening after the `pretxtopen` one which I am not too
enthusiastic about.
- the `mq` extensions + the `record` extension stacks many layers of call
to implement `qrefresh --interactive` and this result with `mq` calling a
`strip` in the middle of this function. Which prevent the existence of
transaction wrapping all of its function code. (however, `qrefresh` never
call the `addremove` bits.
- the largefile extensions (and maybe other extensions?) wraps `addremove`
so slicing `addremove` in smaller bits is a complex endeavour.
So I eventually took a this shortcut that open the transaction if we
actually needs it, not disturbing much of the rest of the code.
It will result in some hooks order change for `hg commit --addremove`,
however it seems a corner case enough to ignore that for now (hopefully).
Notes that None of the above problems seems insurmountable, however I have
been fighting with this specific piece of code for a couple of day already
and I need a solution to keep moving forward on the bigger work around
`changing_files` context that is being introduced at the same time as this
hack.
Each problem seems to have a solution:
- the hook order issue could be solved by refactoring the many-layer stack
that currently composes a commit and calling them earlier,
- the mq issue could be solved by refactoring `mq` so that the final strip
is done after transaction closure. Be warned that the mq code is quite
antic however.
- large-file could be reworked in parallel of the `addremove` to be
friendlier to this.
However each of these tasks are too much a diversion right now. In addition
they will be much easier to undertake when the `changing_files` dust has
settled."""
