e13f37f7b7 sequencer: lib'ify save_todo()
Instead of dying there, let the caller high up in the callchain notice
the error and handle it (by dying, still).

The only caller of save_todo(), pick_commits() can already return
errors, so its caller must be already prepared to handle error
returns, and with this step, we make it notice an error return from
this function.

So this is a safe conversion to make save_todo() callable
from new callers that want it not to die, without changing the
external behaviour of anything existing.

70b059f1f6 sequencer: lib'ify read_populate_opts()
Instead of dying there, let the caller high up in the callchain notice
the error and handle it (by dying, still).

The only caller of read_populate_opts(), sequencer_continue() can
already return errors, so its caller must be already prepared to
handle error returns, and with this step, we make it notice an error
return from this function.

So this is a safe conversion to make read_populate_opts() callable
from new callers that want it not to die, without changing the
external behaviour of anything existing.

Note that the function git_config_from_file(), called from
read_populate_opts(), can currently still die() (in git_parse_source(),
because the do_config_from_file() function sets die_on_error = 1). We do
not try to fix that here, as it would have larger ramifications on the
config code, and we also assume that we write the opts file
programmatically, hence any parse errors would be bugs.

1fa21d077b sequencer: lib'ify read_and_refresh_cache()
Instead of dying there, let the caller high up in the callchain
notice the error and handle it (by dying, still).

There are two call sites of read_and_refresh_cache(), one of which is
pick_commits(), whose callers were already prepared to do the right
thing given an "error" return from it by an earlier patch, so the
conversion is safe.

The other one, sequencer_pick_revisions() was also prepared to relay
an error return back to its caller in all remaining cases in an
earlier patch.

sha1: use openssl sha1 routines on mingw
2016-10-13 10:43:30 +02:00

8d16184360 sha1: Use OpenSSL SHA1 routines on MINGW
Use OpenSSL SHA1 routines rather than builtin block-sha1 routines.
This improves performance on SHA1 operations on Intel processors.

OpenSSL 1.0.2 has made considerable performance improvements and
support the Intel hardware acceleration features.  See:
https://software.intel.com/en-us/articles/improving-openssl-performance
https://software.intel.com/en-us/articles/intel-sha-extensions

To test this I added/staged a single file in a gigantic
repository having a 450MB index file.  The code in read-cache.c
verifies the header SHA as it reads the index and computes a new
header SHA as it writes out the new index.  Therefore, in this test
the SHA code must process 900MB of data.  Testing was done on an
Intel I7-4770 CPU @ 3.40GHz (Intel64, Family 6, Model 60) CPU.

The block-sha1 version averaged 5.27 seconds.
The OpenSSL    version averaged 4.50 seconds.

953b03ca99 Unbreak interactive GPG prompt upon signing
With the recent update in efee955 (gpg-interface: check gpg signature
creation status, 2016-06-17), we ask GPG to send all status updates to
stderr, and then catch the stderr in an strbuf.

But GPG might fail, and send error messages to stderr. And we simply
do not show them to the user.

Even worse: this swallows any interactive prompt for a passphrase. And
detaches stderr from the tty so that the passphrase cannot be read.

So while the first problem could be fixed (by printing the captured
stderr upon error), the second problem cannot be easily fixed, and
presents a major regression.

So let's just revert commit efee9553a4.

65c9476035 git-gui (Windows): use git-gui.exe in Create Desktop Shortcut
When calling `Repository>Create Desktop Shortcut`, Git GUI assumes
that it is okay to call `wish.exe` directly on Windows. However, in
Git for Windows 2.x' context, that leaves several crucial environment
variables uninitialized, resulting in a shortcut that does not work.

To fix those environment variable woes, Git for Windows comes with a
convenient `git-gui.exe`, so let's just use it when it is available.

6112fa2ac4 mingw: abort on invalid strftime formats
On Windows, strftime() does not silently ignore invalid formats, but
warns about them and then returns 0 and sets errno to EINVAL.

Unfortunately, Git does not expect such a behavior, as it disagrees
with strftime()'s semantics on Linux. As a consequence, Git
misinterprets the return value 0 as "I need more space" and grows the
buffer. As the larger buffer does not fix the format, the buffer grows
and grows and grows until we are out of memory and abort.

Ideally, we would switch off the parameter validation just for
strftime(), but we cannot even override the invalid parameter handler
via _set_thread_local_invalid_parameter_handler() using MINGW because
that function is not declared. Even _set_invalid_parameter_handler(),
which *is* declared, does not help, as it simply does... nothing.

So let's just bite the bullet and override strftime() for MINGW and
abort on an invalid format string. While this does not provide the
best user experience, it is the best we can do.

See https://msdn.microsoft.com/en-us/library/fe06s4ak.aspx for more
details.

4e7bc96f7b Preliminary support for reporting build platform
Add preliminary support for detection of the build plaform, and reporting
of same with the `git version --build-options' command. This can be useful
for bug reporting, to distinguish between 32 and 64-bit builds for
example.

The current implementation can only distinguish between x86 and x86_64.
This will be extended in future patches. In addition, all 32-bit variants
(i686, i586, etc.) are collapsed into `x86'. An example of the output is:

   $ git version --build-options
   git version 2.9.3.windows.2.826.g06c0f2f
   sizeof-long: 4
   machine: x86_64

The label of `machine' was chosen so the new information will approximate
the output of `uname -m'.

272fe0b414 rebase -i: rearrange fixup/squash lines using the rebase--helper
This operation has quadratic complexity, which is especially painful
on Windows, where shell scripts are *already* slow (mainly due to the
overhead of the POSIX emulation layer).

Let's reimplement this with linear complexity (using a hash map to
match the commits' subject lines) for the common case; Sadly, the
fixup/squash feature's design neglected performance considerations,
allowing arbitrary prefixes (read: `fixup! hell` will match the
commit subject `hello world`), which means that we are stuck with
quadratic performance in the worst case.

The reimplemented logic also happens to fix a bug where commented-out
lines (representing empty patches) were dropped by the previous code.

9795897f40 t3415: test fixup with wrapped oneline
The `git commit --fixup` command unwraps wrapped onelines when
constructing the commit message, without wrapping the result.

We need to make sure that `git rebase --autosquash` keeps handling such
cases correctly, in particular since we are about to move the autosquash
handling into the rebase--helper.
