Revision 1ca3d6ed01774eab37e96d9c88b840ea618f97af authored by Jay Soffian on 20 February 2008, 05:55:07 UTC, committed by Junio C Hamano on 20 February 2008, 10:47:54 UTC
The check to see if initial_reply_to is defined was also comparing $_ to "" for a reason I cannot ascertain (looking at the commit which made the change didn't provide enlightenment), but if $_ is undefined, perl generates a warning.

/*
* The first four bytes of index formats later than version 1 should
* start with this signature, as all older git binaries would find this
* value illegal and abort reading the file.
*
* This is the case because the number of objects in a packfile
* cannot exceed 1,431,660,000 as every object would need at least
* 3 bytes of data and the overall packfile cannot exceed 4 GiB with
* version 1 of the index file due to the offsets limited to 32 bits.
* Clearly the signature exceeds this maximum.
*
* Very old git binaries will also compare the first 4 bytes to the
* next 4 bytes in the index and abort with a "non-monotonic index"
* error if the second 4 byte word is smaller than the first 4
* byte word. This would be true in the proposed future index
* format as idx_signature would be greater than idx_version.
