[PATCH v3 00/27] Builtin FSMonitor Part 3

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Here is V3 of Part 3 of my builtin FSMonitor series.

I have addressed all of the feedback from Part 3 V2 and the mess that was
Part 2.5 (now obsolete). This version builds upon the new V7 of Part 2
(which includes 2.5).

This version includes: (1) fixup a few more "_()" calls in die() and error()
messages. (2) refactor how fsmonitor incompatibility error messages are
formatted (3) make use of new "start_daemon()" function t7527 to reduce
duplicated code. (4) improve documentation around Unicode/UTF8 testing on
MacOS.

Here is the range-diff from V2 to V3:
