Most Git developers work on Linux and they have no way to know if their
changes would break the Git for Windows build. Let's fix that by adding
a job to TravisCI that builds and tests Git on Windows. Unfortunately,
TravisCI does not support Windows.
Therefore, we did the following:
* Johannes Schindelin set up a Visual Studio Team Services build
sponsored by Microsoft and made it accessible via an Azure Function
that speaks a super-simple API. We made TravisCI use this API to
trigger a build, wait until its completion, and print the build and
test results.
* A Windows build and test run takes up to 3h and TravisCI has a timeout
after 50min for Open Source projects. Since the TravisCI job does not
use heavy CPU/memory/etc. resources, the friendly TravisCI folks
extended the job timeout for git/git to 3h.
Things, that would need to be done:
* Someone with write access to https://travis-ci.org/git/git would need
to add the secret token as "GFW_CI_TOKEN" variable in the TravisCI
repository setting [1]. Afterwards the build should just work.
Things, that might need to be done:
* The Windows box can only process a single build at a time. A second
Windows build would need to wait until the first finishes. This
waiting time and the build time after the wait could exceed the 3h
threshold. If this is a problem, then it is likely to happen every day
as usually multiple branches are pushed at the same time (pu/next/
master/maint). I cannot test this as my TravisCI account has the 50min
timeout. One solution could be to limit the number of concurrent
TravisCI jobs [2].

To avoid needing to specify a constant, reject shallow lines with the

Note that in queue_command we are guaranteed to have a NUL-terminated
buffer or at least one byte of overflow that we can safely read, so the
linelen check can be elided. We would die in such a case, but not read

If we had already processed the last newline in a push certificate, we
would end up subtracting NULL from the end-of-certificate pointer when
computing the length of the line. This would have resulted in an
absurdly large length, and possibly a buffer overflow. Instead,
subtract the beginning-of-certificate pointer from the
end-of-certificate pointer, which is what's expected.
Note that this situation should never occur, since not only do we
require the certificate to be newline terminated, but the signature will
only be read from the beginning of a line. Nevertheless, it seems
prudent to correct it.

After a note is removed, note_tree_consolidate is called to eliminate
some useless nodes. The typical case is that if you had an int_node
with 2 PTR_TYPE_NOTEs in it, and remove one of them, then the
PTR_TYPE_INTERNAL pointer in the parent tree can be replaced with the
remaining PTR_TYPE_NOTE.
This works fine when PTR_TYPE_NOTEs are involved, but falls flat when
other types are involved.
To put things in more practical terms, let's say we start from an empty
notes tree, and add 3 notes:
- one for a sha1 that starts with 424
- one for a sha1 that starts with 428
- one for a sha1 that starts with 4c
To keep track of this, note_tree.root will have a PTR_TYPE_INTERNAL at
a[4], pointing to an int_node*.
In turn, that int_node* will have a PTR_TYPE_NOTE at a[0xc], pointing to
the leaf_node* with the key and value, and a PTR_TYPE_INTERNAL at a[2],
pointing to another int_node*.
That other int_node* will have 2 PTR_TYPE_NOTE, one at a[4] and the
other at a[8].
When looking for the note for the sha1 starting with 428, get_note() will
recurse through (simplified) root.a[4].a[2].a[8].
Now, if we remove the note for the sha1 that starts with 4c, we're left
with a int_node* with only one PTR_TYPE_INTERNAL entry in it. After
note_tree_consolidate runs, root.a[4] now points to what used to be
pointed at by root.a[4].a[2].
Which means looking up for the note for the sha1 starting with 428 now
fails because there is nothing at root.a[4].a[2] anymore: there is only
root.a[4].a[4] and root.a[4].a[8], which don't match the expected
structure for the lookup.
So if all there is left in an int_node* is a PTR_TYPE_INTERNAL pointer,
we can't safely remove it. I think the same applies for PTR_TYPE_SUBTREE
pointers. IOW, only PTR_TYPE_NOTEs are safe to be moved to the parent
int_node*.
This doesn't have a practical effect on git because all that happens
after a remove_note is a write_notes_tree, which just iterates the entire
note tree, but this affects anything using libgit.a that would try to do
lookups after removing notes.

The `reword` command used to call `git commit` in a manner that asks for
the prepare-commit-msg and commit-msg hooks to do their thing.
Converting that part of the interactive rebase to C code introduced the
regression where those hooks were no longer run.
Let's fix this.
Note: the flag is called `VERIFY_MSG` instead of the more intuitive
`RUN_COMMIT_MSG_HOOKS` to indicate that the flag suppresses the
`--no-verify` flag (which may do other things in the future in addition
to suppressing the commit message hooks, too).

So far every time we need to tweak the behaviour of run_git_commit()
we have been adding a "int" parameter to it. As the function gains
parameters and different callsites having different needs, this is
becoming a maintenance burden. When a new knob needs to be added to
address a specific need for a single callsite, all the other callsites
need to add a "no, I do not want anything special with respect to the
new knob" argument.
Consolidate the existing four parameters into a flag word to make it
more maintainable, as we will be adding a new one to the mix soon.

Change the revision parsing logic to match @{upstream}, @{u} & @{push}
case-insensitively.
Before this change supplying anything except the lower-case forms
emits an "unknown revision or path not in the working tree"
error. This change makes upper-case & mixed-case versions equivalent
to the lower-case versions.
The use-case for this is being able to hold the shift key down while
typing @{u} on certain keyboard layouts, which makes the sequence
easier to type, and reduces cases where git throws an error at the
user where it could do what he means instead.
These suffixes now join various other suffixes & special syntax
documented in gitrevisions(7) that matches case-insensitively. A table
showing the status of the various forms documented there before &
after this patch is shown below. The key for the table is:
- CI = Case Insensitive
- CIP = Case Insensitive Possible (without ambiguities)
- AG = Accepts Garbage (.e.g. @{./.4.minutes./.})
Before this change:
|----------------+-----+------+-----|
| What? | CI? | CIP? | AG? |
|----------------+-----+------+-----|
| @{<date>} | Y | Y | Y |
| @{upstream} | N | Y | N |
| @{push} | N | Y | N |
|----------------+-----+------+-----|
After it:
|----------------+-----+------+-----|
| What? | CI? | CIP? | AG? |
|----------------+-----+------+-----|
| @{<date>} | Y | Y | Y |
| @{upstream} | Y | Y | N |
| @{push} | Y | Y | N |
|----------------+-----+------+-----|
The ^{<type>} suffix is not made case-insensitive, because other
places that take <type> like "cat-file -t <type>" do want them case
sensitively (after all we never declared that type names are case
insensitive). Allowing case-insensitive typename only with this syntax
will make the resulting Git as a whole inconsistent.
This change was independently authored to scratch a longtime itch, but
when I was about to submit it I discovered that a similar patch had
been submitted unsuccessfully before by Conrad Irwin in August 2011 as
"rev-parse: Allow @{U} as a synonym for
@{u}" (<1313287071-7851-1-git-send-email-conrad.irwin@gmail.com>).
The tests for this patch are more exhaustive than in the 2011
submission. The starting point for them was to first change the code
to only support upper-case versions of the existing words, seeing what
broke, and amending the breaking tests to check upper case & mixed
case as appropriate, and where not redundant to other similar
tests. The implementation itself is equivalent.

path to where real submodule gitdir is located is done in get_ref_store().
