There are situations where squashing commits is not favourable and is an anti-pattern.

Squashing is necessary when a series of commits represents an atomic unit of work, where an atomic unit of work is any work which if broken into two or more independent commits would render either or both of them functionally incomplete. as an extreme example, changing a single global variable name across two commits would likely break the first commit and so the two commits should be squashed. They should also be squashed because the two commits are thematically one (although thematic unity can be relative), but I view this as a less important reason. At any point, one should be able to go back to a given commit on master and ensure all tests pass.

Squashing should be avoided in situations where each commit in a given series is atomic, even if the commits deliver a feature in combination (unless, as alluded to above, some commits break the codebase in isolation). Incremental commits often represent the logical sequence o

I recently came across the need to spawn multiple threads, each of which needs to write to the same file. Since the file will experience contention from multiple resources, we need to guarantee thread-safety.

NOTE: The following examples work with Python 3.x. To execute the following programs using Python 2.7, please replace threading.get_ident() with thread.get_ident(). As a result, you would need to import thread and not threading.

1. (The following example will take a very long time). It will create 200 threads, each of which will wait until a global lock is available for acquisition.
