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.
