The script then calls 'eval' and sets 'is_completed' to 1 thinking it is setting its own variable, completely unaware of how the chord works behind the scenes. This leads to the chord never actually executing because it sees 'is_completed' as true and thinks it has already completed. Avoid the potential collision by creating a separate namespace for the script that is a child of the chord's namespace. Signed-off-by: Pratyush Yadav <me@yadavpratyush.com>	5 years ago

git-gui: create a new namespace for chord script evaluation

Evaluating the script in the same namespace as the chord itself creates
potential for variable name collision. And in that case the script would
unknowingly use the chord's variables.

For example, say the script has a variable called 'is_completed', which
also exists in the chord's namespace. The script then calls 'eval' and
sets 'is_completed' to 1 thinking it is setting its own variable,
completely unaware of how the chord works behind the scenes. This leads
to the chord never actually executing because it sees 'is_completed' as
true and thinks it has already completed.

Avoid the potential collision by creating a separate namespace for the
script that is a child of the chord's namespace.

git-gui: reduce Tcl version requirement from 8.6 to 8.5

On some MacOS distributions like High Sierra, Tcl 8.5 is shipped by
default. This makes git-gui error out at startup because of the version
mismatch.

The only part that requires Tcl 8.6 is SimpleChord, which depends on
TclOO. So, don't use it and use our homegrown class.tcl instead.

This means some slight syntax changes. Since class.tcl doesn't have an
"unknown" method like TclOO does, we can't just call '$note', but have
to use '$note activate' instead. The constructor now needs a proper
namespace qualifier. Update the documentation to reflect the new syntax.

As of now, the only part of git-gui that needs Tcl 8.5 is a call to
'apply' in lib/index.tcl::lambda. Keep using it until someone shows up

git-gui: revert untracked files by deleting them

Update the revert_helper proc to check for untracked files as well as
changes, and then handle changes to be reverted and untracked files with
independent blocks of code. Prompt the user independently for untracked
files, since the underlying action is fundamentally different (rm -f).
If after deleting untracked files, the directory containing them becomes
empty, then remove the directory as well. Migrate unlocking of the index
out of _close_updateindex to a responsibility of the caller, to permit
paths that don't directly unlock the index, and refactor the error
handling added in d4e890e5 so that callers can make flow control
decisions in the event of errors. Update Tcl/Tk dependency from 8.4 to
8.6 in git-gui.sh.

A new proc delete_files takes care of actually deleting the files in
batches, using the Tcler's Wiki recommended approach for keeping the UI
responsive.

Since the checkout_index and delete_files calls are both asynchronous
and could potentially complete in any order, a "chord" is used to
coordinate unlocking the index and returning the UI to a usable state
only after both operations are complete. The `SimpleChord` class,
based on TclOO (Tcl/Tk 8.6), is added in this commit.
