Package: lzma
Version: 9.22-2
Severity: important
Dear Maintainer,
I tried to compress a large file using lzma. But lzma failed to open the file.
The command line was
lzma -v9 filtermail.log
lzma failed with an error message 'Cannot open input file filtermail.log'.
The file in question is 23GB:
: nr@labrador 12746 ; ls -lh filtermail.log
-rw-r--r-- 1 nr nr 23G Oct 15 13:17 filtermail.log
: nr@labrador 12747 ; ls -l filtermail.log
-rw-r--r-- 1 nr nr 23732206014 Oct 15 13:17 filtermail.log
: nr@labrador 12748 ;
Here is some information from strace:
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =

mprotect(0xb7739000, 16384, PROT_READ) = 0

open("filtermail.log", O_RDONLY) = -1 EOVERFLOW (Value too large for
defined data type)
write(2, "lzma", 4lzma) = 4
write(2, ": ", 2: ) = 2
write(2, "Cannot open input file filtermai"..., 37Cannot open input file
filtermail.log) = 37
write(2, "\n", 1
) = 1
exit_group(1)
I expected lzma to compress the file.
N.B. gzip -v9 is compressing the file now.
