*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

"""This starts an SSH tunnel to a given host. If the SSH process ever dies then
|
|
this script will detect that and restart it. I use this under Cygwin to keep
|
|
open encrypted tunnels to port 25 (SMTP), port 143 (IMAP4), and port 110
|
|
(POP3). I set my mail client to talk to localhost and I keep this script
|
|
running in the background.
|
|
|
|
Note that this is a rather stupid script at the moment because it just looks to
|
|
see if any ssh process is running. It should really make sure that our specific
|
|
ssh process is running. The problem is that ssh is missing a very useful
|
|
feature. It has no way to report the process id of the background daemon that
|
|
it creates with the -f command. This would be a really useful script if I could
|
|
figure a way around this problem. """
