Subject: [PATCH 0/6] Use time_t
Date: Mon, 27 Feb 2017 22:30:20 +0100 (CET) [thread overview]
Message-ID: <cover.1488231002.git.johannes.schindelin@gmx.de> (raw)
Git v2.9.2 was released in a hurry to accomodate for platforms like
Windows, where the `unsigned long` data type is 32-bit even for 64-bit
setups.
The quick fix was to simply disable all the testing with "absurd" future
dates.
However, we can do much better than that, as `time_t` exists, and at
least on 64-bit Windows it is 64-bit. Meaning: we *can* support these
absurd future dates on those platforms.
So let's do this.
One notable fallout of this patch series is that on 64-bit Linux (and
other platforms where `unsigned long` is 64-bit), we now limit the range
of dates to LONG_MAX (i.e. the *signed* maximum value). This needs to be
done as `time_t` can be signed (and indeed is at least on my Ubuntu
setup).
Obviously, I think that we can live with that, and I hope that all
interested parties agree.
Johannes Schindelin (6):
t0006 & t5000: prepare for 64-bit time_t
Specify explicitly where we parse timestamps
Introduce a new "printf format" for timestamps
Prepare for timestamps to use 64-bit signed types
ref-filter: avoid using `unsigned long` for catch-all data type
Use time_t where appropriate
