2016-07-13pack-objects: do not truncate result in-pack object size on 32-bit systemsLibravatar Nguyễn Thái Ngọc Duy1-7/+8
A typical diff will not show what's going on and you need to see full functions. The core code is like this, at the end of of write_one() e->idx.offset = *offset; size = write_object(f, e, *offset); if (!size) { e->idx.offset = recursing; return WRITE_ONE_BREAK; } written_list[nr_written++] = &e->idx; /* make sure off_t is sufficiently large not to wrap */ if (signed_add_overflows(*offset, size)) die("pack too large for current definition of off_t"); *offset += size; Here we can see that the in-pack object size is returned by write_object (or indirectly by write_reuse_object). And it's used to calculate object offsets, which end up in the pack index file, generated at the end. If "size" overflows (on 32-bit sytems, unsigned long is 32-bit while off_t can be 64-bit), we got wrong offsets and produce incorrect .idx file, which may make it look like the .pack file is corrupted.

2016-07-13index-pack: correct "offset" type in unpack_entry_data()Libravatar Nguyễn Thái Ngọc Duy1-1/+1
unpack_entry_data() receives an off_t value from unpack_raw_entry(), which could be larger than unsigned long on 32-bit systems with large file support. Correct the type so truncation does not happen. This only affects bad object reporting though.

2016-07-13index-pack: report correct bad object offsets even if they are largeLibravatar Nguyễn Thái Ngọc Duy1-3/+4
Use the right type for offsets in this case, off_t, which makes a difference on 32-bit systems with large file support, and change formatting code accordingly. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-07-13index-pack: correct "len" type in unpack_data()Libravatar Nguyễn Thái Ngọc Duy1-7/+7
On 32-bit systems with large file support, one entry could be larger than 4GB and overflow "len". Correct it so we can unpack a full entry. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-07-13sha1_file.c: use type off_t* for object_info->disk_sizepLibravatar Nguyễn Thái Ngọc Duy2-3/+3
This field, filled by sha1_object_info() contains the on-disk size of an object, which could go over 4GB limit of unsigned long on 32-bit systems. Use off_t for it instead and update all callers.

2016-07-12pack-objects: pass length to check_pack_crc() without truncationLibravatar Nguyễn Thái Ngọc Duy2-2/+2
On 32 bit systems with large file support, unsigned long is 32-bit while the two offsets in the subtraction expression (pack-objects has the exact same expression as in sha1_file.c but not shown in diff) are in 64-bit. If an in-pack object is larger than 2^32 len/datalen is truncated and we get a misleading "error: bad packed object CRC for ..." as a result. Use off_t for len and datalen. check_pack_crc() already accepts this argument as off_t and can deal with 4+ GB.

Running tests with '-x' option to trace the individual command executions is a useful way to debug test scripts, but some tests that capture the standard error stream and check what the command said can be broken with the trace output mixed in. When running our tests under "bash", however, we can redirect the trace output to another file descriptor to keep the standard error of programs being tested intact. * jk/test-send-sh-x-trace-elsewhere: test-lib: set BASH_XTRACEFD automatically
2016-05-31Merge branch 'js/name-rev-use-oldest-ref' into maintLibravatar Junio C Hamano2-7/+14
"git describe --contains" often made a hard-to-justify choice of tag to give name to a given commit, because it tried to come up with a name with smallest number of hops from a tag, causing an old commit whose close descendant that is recently tagged were not described with respect to an old tag but with a newer tag. It did not help that its computation of "hop" count was further tweaked to penalize being on a side branch of a merge. The logic has been updated to favor using the tag with the oldest tagger date, which is a lot easier to explain to the end users: "We describe a commit in terms of the (chronologically) oldest tag that contains the commit." * js/name-rev-use-oldest-ref: name-rev: include taggerdate in considering the best name

2016-05-26mingw: make isatty() recognize MSYS2's pseudo terminals (/dev/pty*)Libravatar Karsten Blees2-5/+56
MSYS2 emulates pseudo terminals via named pipes, and isatty() returns 0 for such file descriptors. Therefore, some interactive functionality (such as launching a pager, asking if a failed unlink should be repeated etc.) doesn't work when run in a terminal emulator that uses MSYS2's ptys (such as mintty). However, MSYS2 uses special names for its pty pipes ('msys-*-pty*'), which allows us to distinguish them from normal piped input / output. On startup, check if stdin / stdout / stderr are connected to such pipes using the NtQueryObject API from NTDll.dll. If the names match, adjust the flags in MSVCRT's ioinfo structure accordingly.

2016-05-26archive-tar: convert snprintf to xsnprintfLibravatar Jeff King1-1/+1
Commit f2f0267 (archive-tar: use xsnprintf for trivial formatting, 2015-09-24) converted cases of "sprintf" to "xsnprintf", but accidentally left one as just "snprintf". This meant that we could silently truncate the resulting buffer instead of flagging an error. In practice, this is impossible to achieve, as we are formatting a ustar checksum, which can be at most 7 characters. But the point of xsnprintf is to document and check for "should be impossible" conditions; this site was just accidentally mis-converted during f2f0267.
