If a file is removed from the index and then modified in the working
tree then stash will discard the working tree file with no way to
recover the changes.
This can might be done in one of a number of ways.
git rm file
vi file # edit a new version
git stash
or with git mv
git mv file newfile
vi file # make a new file with the old name
git stash

When pushing to a remote repo the sending side filters out aliased
updates (e.g., foo:baz bar:baz). However, it is not possible for the
sender to know if two refs are aliased on the receiving side via
symrefs. Here is one such scenario:
$ git init origin
$ (cd origin && touch file && git add file && git commit -a -m intial)
$ git clone --bare origin origin.git
$ rm -rf origin
$ git clone origin.git client
$ git clone --mirror client backup.git &&
$ (cd backup.git && git remote set-head origin --auto)
$ (cd client &&
git remote add --mirror backup ../backup.git &&
echo change1 > file && git commit -a -m change1 &&
git push origin &&
git push backup
)
The push to backup fails with:
Counting objects: 5, done.
Writing objects: 100% (3/3), 244 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
error: Ref refs/remotes/origin/master is at ef3... but expected 262...
remote: error: failed to lock refs/remotes/origin/master
To ../backup.git
262cd57..ef307ff master -> master
262cd57..ef307ff origin/HEAD -> origin/HEAD
! [remote rejected] origin/master -> origin/master (failed to lock)
error: failed to push some refs to '../backup.git'
The reason is that refs/remotes/origin/HEAD is a symref to
refs/remotes/origin/master, but it is not possible for the sending side
to unambiguously know this.
This commit fixes the issue by having receive-pack ignore any update to
a symref whose target is being identically updated. If a symref and its
target are being updated inconsistently, then the update for both fails
with an error message ("refusing inconsistent update...") to help
diagnose the situation.

Receive-pack is inconsistent in its usage of the 'commands'
variable; though it is setup as a global and accessed that way by
execute_commands(), report(), and run_receive_hook(), it is also
passed as a parameter to delete_only() and run_update_post_hook().
For consistency, make it local to cmd_receive_pack and pass it as a
parameter. As long as we're cleaning up, also make our use of the
names 'commands' and 'cmd' consistent.

When passed an empty list, objects_array_remove_duplicates() corrupts it
by changing the number of entries from 0 to 1.
The problem lies in the condition of its main loop:
for (ref = 0; ref < array->nr - 1; ref++) {
The loop body manipulates the supplied object array. In the case of an
empty array, it should not be doing anything at all. But array->nr is an
unsigned quantity, so the code enters the loop, in particular increasing
array->nr. Fix this by comparing (ref + 1 < array->nr) instead.
This bug can be triggered by git bundle --stdin:
$ echo HEAD | git bundle create some.bundle --stdin’
Segmentation fault (core dumped)
The list of commits to bundle appears to be empty because of another bug:
by the time the revision-walking machinery gets to look at it, standard
input has already been consumed by rev-list, so this function gets an
empty list of revisions.
After this patch, git bundle --stdin still does not work; it just doesn’t
segfault any more.

Verify that a downloaded pack-*.idx file is consistent and valid
as an index file before we rename it into its final destination.
This prevents a corrupt index file from later being treated as a
usable file, confusing readers.
Check that we do not have the pack index file before invoking
fetch_pack_index(); that way, we can do without the has_pack_index()
check in fetch_pack_index().

To ensure we don't leave a corrupt pack file positioned as though
it were a valid pack file, run index-pack on the temporary pack
before we rename it to its final name. If index-pack crashes out
when it discovers file corruption (e.g. GitHub's error HTML at the
end of the file), simply delete the temporary files to cleanup.
By waiting until the pack has been validated before we move it
to its final name, we eliminate a race condition where another
concurrent reader might try to access the pack at the same time
that we are still trying to verify its not corrupt.
Switching from verify-pack to index-pack is a change in behavior,
but it should turn out better for users. The index-pack algorithm
tries to minimize disk seeks, as well as the number of times any
given object is inflated, by organizing its work along delta chains.
The verify-pack logic does not attempt to do this, thrashing the
delta base cache and the filesystem cache.
By recreating the index file locally, we also can automatically
upgrade from a v1 pack table of contents to v2. This makes the
CRC32 data available for use during later repacks, even if the
server didn't have them on hand.

The easiest way to verify a pack index is to open it through the
standard parse_pack_index function, permitting the header check
to happen when the file is mapped. However, the dumb HTTP client
needs to verify a pack index before its moved into its proper file
name within the objects/pack directory, to prevent a corrupt index
from being made available. So permit the caller to specify the
exact path of the index file.
For now we're still using the final destination name within the
sole call site in http.c, but eventually we will start to parse
the temporary path instead.

The dumb HTTP transport should verify an index is completely valid
before trying to use it. That requires checking the header/footer
but also checking the complete content SHA-1. All of this logic is
already in the front half of verify_pack, so pull it out into a new
function that can be reused.

By closing the pack index, a caller can later overwrite the index
with an updated index file, possibly after converting from v1 to
the v2 format. Because p->index_data is NULL after close, on the
next access the index will be opened again and the other members
will be updated with new data.

Most of the time the dumb HTTP transport is run without the verbose
flag set, so we only need the result of sha1_to_hex(sha1) once, to
construct the pack URL. Don't bother with an unnecessary malloc,
copy, free chain of this buffer.
If verbose is set, we'll format the SHA-1 twice now. But this
tiny extra CPU time spent is nothing compared to the slowdown that
is usually imposed by the verbose messages being sent to the tty,
and is entirely trivial compared to the latency involved with the
remote HTTP server sending something as big as a pack file.

I have an alias that takes two arguments and compares their patch IDs.
I would like to use to make sure I've tested exactly what I submit
(patch by patch), like
git patch-cmp origin/master.. file-being-sent
However, I cannot do that because git patch-id is fooled by the "-- "
trailer that git format-patch puts, or likely by the MIME boundary.
This patch adds hunk parsing logic to git patch-id in order to detect an
out of place "-" line and split the patch when it comes. In addition,
commit ids in the "From " lines are considered and printed in the output.
