As this developer has no access to MacOSX developer setups anymore,
Travis becomes the best bet to run performance tests on that OS.

However, on MacOSX /usr/bin/time is that good old BSD executable that
no Linux user cares about, as demonstrated by the perf-lib.sh's use
of GNU-ish extensions. And by the hard-coded path.

Let's just work around this issue by using gtime on MacOSX, the
Homebrew-provided GNU implementation onto which pretty much every
MacOSX power user falls back anyway.

To help other developers use Travis to run performance tests on
MacOSX, the .travis.yml file now sports a commented-out line that

local_tzoffset: detect errors from tm_to_time_tJeff King Mon, 20 Jun 2016 21:14:14 +0000 (17:14 -0400)

local_tzoffset: detect errors from tm_to_time_t

When we want to know the local timezone offset at a given
timestamp, we compute it by asking for localtime() at the
given time, and comparing the offset to GMT at that time.
However, there's some juggling between time_t and "struct
tm" which happens, which involves calling our own
tm_to_time_t().

If that function returns an error (e.g., because it only
handles dates up to the year 2099), it returns "-1", which
we treat as a time_t, and is clearly bogus, leading to
bizarre timestamps (that seem to always adjust the time back
to (time_t)(uint32_t)-1, in the year 2106).

It's not a good idea for local_tzoffset() to simply die
here; it would make it hard to run "git log" on a repository
with funny timestamps. Instead, let's just treat such cases
as "zero offset".

The iterator interface is modeled on that for references, though no

There are obviously a lot of features that could easily be added to this
class:

* Skip/include directory paths in the iteration
* Shallow/deep iteration
* Letting the caller decide which subdirectories to recurse into (e.g.,
via a dir_iterator_advance_into() function)
* Option to iterate in sorted order
* Option to iterate over directory paths before vs. after their contents

But these are not needed for the current patch series, so I refrain.

* None of the callers was checking the exit value

* The callers all want to find all legitimate reflogs (sometimes for the

a truncated iteration anyway.

So instead, emit an error message and skip the "broken" reflog, but
continue with the iteration.

do_for_each_ref(): reimplement using reference iterationMichael Haggerty Sat, 18 Jun 2016 04:15:16 +0000 (06:15 +0200)

do_for_each_ref(): reimplement using reference iteration

Use the reference iterator interface to implement do_for_each_ref().
Delete a bunch of code supporting the old for_each_ref() implementation.
And now that do_for_each_ref() is generic code (it is no longer tied to
the files backend), move it to refs.c.

The implementation is via a new function, do_for_each_ref_iterator(),
which takes a reference iterator as argument and calls a callback
function for each of the references in the iterator.

This change requires the current_ref performance hack for peel_ref() to
be implemented via ref_iterator_peel() rather than peel_entry() because
we don't have a ref_entry handy (it is hidden under three layers:
file_ref_iterator, merge_ref_iterator, and cache_ref_iterator). So:

* do_for_each_ref_iterator() records the active iterator in
current_ref_iter while it is running.

* peel_ref() checks whether current_ref_iter is pointing at the
requested reference. If so, it asks the iterator to peel the
reference (which it can do efficiently via its "peel" virtual
function). For extra safety, we do the optimization only if the
refname *addresses* are the same, not only if the refname *strings*
are the same, to forestall possible mixups between refnames that come
from different ref_iterators.

Please note that this optimization of peel_ref() is only available when
iterating via do_for_each_ref_iterator() (including all of the
for_each_ref() functions, which call it indirectly). It would be
complicated to implement a similar optimization when iterating directly
using a reference iterator, because multiple reference iterators can be
in use at the same time, with interleaved calls to
ref_iterator_advance(). (In fact we do exactly that in
merge_ref_iterator.)

But that is not necessary. peel_ref() is only called while iterating
over references. Callers who iterate using the for_each_ref() functions
benefit from the optimization described above. Callers who iterate using
reference iterators directly have access to the ref_iterator, so they
can call ref_iterator_peel() themselves to get an analogous optimization
in a more straightforward manner.

If we rewrite all callers to use the reference iteration API, then we
can remove the current_ref_iter hack permanently.

refs: introduce an iterator interfaceMichael Haggerty Sat, 18 Jun 2016 04:15:15 +0000 (06:15 +0200)

refs: introduce an iterator interface

Currently, the API for iterating over references is via a family of
for_each_ref()-type functions that invoke a callback function for each
selected reference. All of these eventually call do_for_each_ref(),
which knows how to do one thing: iterate in parallel through two
ref_caches, one for loose and one for packed refs, giving loose
references precedence over packed refs. This is rather complicated code,
and is quite specialized to the files backend. It also requires callers
to encapsulate their work into a callback function, which often means
that they have to define and use a "cb_data" struct to manage their
context.

The current design is already bursting at the seams, and will become
even more awkward in the upcoming world of multiple reference storage
backends:

* Per-worktree vs. shared references are currently handled via a kludge
in git_path() rather than iterating over each part of the reference
namespace separately and merging the results. This kludge will cease
to work when we have multiple reference storage backends.

* The current scheme is inflexible. What if we sometimes want to bypass
the ref_cache, or use it only for packed or only for loose refs? What
if we want to store symbolic refs in one type of storage backend and
non-symbolic ones in another?

In the future, each reference backend will need to define its own way of
iterating over references. The crux of the problem with the current
design is that it is impossible to compose for_each_ref()-style
iterations, because the flow of control is owned by the for_each_ref()
function. There is nothing that a caller can do but iterate through all
references in a single burst, so there is no way for it to interleave
references from multiple backends and present the result to the rest of
the world as a single compound backend.

This commit introduces a new iteration primitive for references: a
ref_iterator. A ref_iterator is a polymorphic object that a reference
storage backend can be asked to instantiate. There are three functions
that can be applied to a ref_iterator:

* ref_iterator_advance(): move to the next reference in the iteration
* ref_iterator_abort(): end the iteration before it is exhausted
* ref_iterator_peel(): peel the reference currently being looked at

Iterating using a ref_iterator leaves the flow of control in the hands
of the caller, which means that ref_iterators from multiple
sources (e.g., loose and packed refs) can be composed and presented to
the world as a single compound ref_iterator.

It also means that the backend code for implementing reference iteration
will sometimes be more complicated. For example, the
cache_ref_iterator (which iterates over a ref_cache) can't use the C
stack to recurse; instead, it must manage its own stack internally as
explicit data structures. There is also a lot of boilerplate connected
with object-oriented programming in C.

Eventually, end-user callers will be able to be written in a more
natural way—managing their own flow of control rather than having to
work via callbacks. Since there will only be a few reference backends
but there are many consumers of this API, this is a good tradeoff.

More importantly, we gain composability, and especially the possibility
of writing interchangeable parts that can work with any ref_iterator.

For example, merge_ref_iterator implements a generic way of merging the
contents of any two ref_iterators. It is used to merge loose + packed
refs as part of the implementation of the files_ref_iterator. But it
will also be possible to use it to merge other pairs of reference
sources (e.g., per-worktree vs. shared refs).

Another example is prefix_ref_iterator, which can be used to trim a
prefix off the front of reference names before presenting them to the
caller (e.g., "refs/heads/master" -> "master").

In this patch, we introduce the iterator abstraction and many utilities,
and implement a reference iterator for the files ref storage backend.
(I've written several other obvious utilities, for example a generic way
to filter references being iterated over. These will probably be useful
in the future. But they are not needed for this patch series, so I am
not including them at this time.)

In a moment we will rewrite do_for_each_ref() to work via reference
iterators (allowing some special-purpose code to be discarded), and do
something similar for reflogs. In future patch series, we will expose
the ref_iterator abstraction in the public refs API so that callers can
use it directly.

Implementation note: I tried abstracting this a layer further to allow
generic iterators (over arbitrary types of objects) and generic
utilities like a generic merge_iterator. But the implementation in C was
very cumbersome, involving (in my opinion) too much boilerplate and too
much unsafe casting, some of which would have had to be done on the
caller side. However, I did put a few iterator-related constants in a
top-level header file, iterator.h, as they will be useful in a moment to
implement iteration over directory trees and possibly other types of
iterators in the future.

sh-setup: enclose setting of ${VAR=default} in double-quotes

We often make sure an environment variable is set to
something, either set by the user (in which case we do not
molest it) or set it to our default value (otherwise), with

: ${VAR=default value}

i.e. running the no-op command ":" with ${VAR} as its
parameters (or the default value we supply), relying on that
":" is a no-op.

This pattern, even though it is no-op from correctness point
of view, still can be expensive if the existing value in VAR
has shell glob (because they will be expanded against
filesystem entities) and IFS whitespaces (because the value
need to be split into multiple parameters). Our invocation
of ":" command does not care if the parameter given to it is
after the value in VAR goes through these processing.

Enclosing the whole thing in double-quote, i.e.

: "${VAR=default value}"

avoids paying the unnecessary cost, so let's do so.

When we create a signature, it may happen that gpg returns with
"success" but not with an actual detached signature on stdout.

Check for the correct signature creation status to catch these cases
better. Really, --status-fd parsing is the only way to check gpg status
reliably. We do the same for verify already.

sign_buffer: use pipe_commandJeff King Fri, 17 Jun 2016 23:38:55 +0000 (19:38 -0400)

sign_buffer: use pipe_command

Similar to the prior commit for verify_signed_buffer, the
motivation here is both to make the code simpler, and to
avoid any possible deadlocks with gpg.

In this case we have the same "write to stdin, then read
from stdout" that the verify case had. This is unlikely to
be a problem in practice, since stdout has the detached
signature, which it cannot compute until it has read all of
stdin (if it were a non-detached signature, that would be a
problem, though).

We don't read from stderr at all currently. However, we will
want to in a future patch, so this also prepares us there
(and in that case gpg _does_ write before reading all of the
input, though again, it is unlikely that a key uid will fill
up a pipe buffer).

verify_signed_buffer: use pipe_commandJeff King Fri, 17 Jun 2016 23:38:52 +0000 (19:38 -0400)

verify_signed_buffer: use pipe_command

This is shorter and should make the function easier to
follow. But more importantly, it removes the possibility of
any deadlocks based on reading or writing to gpg.

It's not clear if such a deadlock is possible in practice.

We do write the whole payload before reading anything, so we
could deadlock there. However, in practice gpg will need to
read our whole input to verify the signature, so it will
drain our payload first. It could write an error to stderr
before reading, but it's unlikely that such an error
wouldn't be followed by it immediately exiting, or that the
error would actually be larger than a pipe buffer.

On the writing side, we drain stderr (with the
human-readable output) in its entirety before reading stdout
(with the status-fd data). Running strace on "gpg --verify"
does show interleaved output on the two descriptors:

write(2, "gpg: ", 5) = 5
write(2, "Signature made Thu 16 Jun 2016 0"..., 73) = 73
write(1, "[GNUPG:] SIG_ID tQw8KGcs9rBfLvAj"..., 66) = 66
write(1, "[GNUPG:] GOODSIG 69808639F9430ED"..., 60) = 60
write(2, "gpg: ", 5) = 5
write(2, "Good signature from \"Jeff King <"..., 47) = 47
write(2, "\n", 1) = 1
write(2, "gpg: ", 5) = 5
write(2, " aka \"Jeff King <"..., 49) = 49
write(2, "\n", 1) = 1
write(1, "[GNUPG:] VALIDSIG C49CE24156AF08"..., 135) = 135
write(1, "[GNUPG:] TRUST_ULTIMATE\n", 24) = 24

The second line written to stdout there contains the
signer's UID, which can be arbitrarily long. If it fills the
pipe buffer, then gpg would block writing to its stdout,
while we are blocked trying to read its stderr.

In practice, GPG seems to limit UIDs to 2048 bytes, so
unless your pipe buffer size is quite small, or unless gpg
does not enforce the limit under some conditions, this seems
unlikely in practice.

Still, it is not hard for us to be cautious and just use
pipe_command.

run-command: add pipe_command helperJeff King Fri, 17 Jun 2016 23:38:47 +0000 (19:38 -0400)

run-command: add pipe_command helper

We already have capture_command(), which captures the stdout
of a command in a way that avoids deadlocks. But sometimes
we need to do more I/O, like capturing stderr as well, or
sending data to stdin. It's easy to write code that
deadlocks racily in these situations depending on how fast
the command reads its input, or in which order it writes its
output.

Let's give callers an easy interface for doing this the
right way, similar to what capture_command() did for the
simple case.

The whole thing is backed by a generic poll() loop that can
feed an arbitrary number of buffers to descriptors, and fill
an arbitrary number of strbufs from other descriptors. This
seems like overkill, but the resulting code is actually a
bit cleaner than just handling the three descriptors
(because the output code for stdout/stderr is effectively
duplicated, so being able to loop is a benefit).

verify_signed_buffer: use tempfile objectJeff King Fri, 17 Jun 2016 23:38:43 +0000 (19:38 -0400)

verify_signed_buffer: use tempfile object

We use git_mkstemp to create a temporary file, and try to
clean it up in all exit paths from the function. But that
misses any cases where we die by signal, or by calling die()
in a sub-function. In addition, we missed one of the exit
paths.

Let's convert to using a tempfile object, which handles the
hard cases for us, and add the missing cleanup call. Note
that we would not simply want to rely on program exit to
catch our missed cleanup, as this function may be called
many times in a single program (for the same reason, we use
a static tempfile instead of heap-allocating a new one; that
gives an upper bound on our memory usage).

verify_signed_buffer: drop pbuf variable

If our caller gave us a non-NULL gpg_status parameter, we
write the gpg status into their strbuf. If they didn't, then
we write it to a temporary local strbuf (since we still need
to look at it). The variable "pbuf" adds an extra layer of
indirection so that the rest of the function can just access
whichever is appropriate.

However, the name "pbuf" isn't very descriptive, and it's
easy to get confused about what is supposed to be in it
(especially because we are reading both "status" and
"output" from gpg).

Rather than give it a more descriptive name, we can just use
gpg_status as our indirection pointer. Either it points to
the caller's input, or we can point it directly to our
temporary buffer.

i18n: git-sh-setup.sh: mark strings for translation

Positional arguments, such as $0, $1, etc, need to be stored on shell
variables for use in translatable strings, according to gettext manual
[1].

Add git-sh-setup.sh to LOCALIZED_SH variable in Makefile to enable
extraction of string marked for translation by xgettext.

Source git-sh-i18n in git-sh-setup.sh for gettext support.
git-sh-setup.sh is a shell library to be sourced by other shell scripts.
In order to avoid other scripts from sourcing git-sh-i18n twice, remove
line that sources it from them. Not sourcing git-sh-i18n in any script
that uses gettext would lead to failure due to, for instance, gettextln
not being found.

i18n: bisect: simplify error message for i18n

The message was not being extracted by xgettext, although it was marked
for translation, seemingly because it contained a command substitution.
Moreover, eval_gettext should be used instead of gettext for strings
with substitution.

See step 4. of section 15.5.2.1 Preparing Shell Scripts for
Internationalization from gettext manual [1]:
"Simplify translatable strings so that they don't contain command
substitution ("`...`" or "$(...)") [...]"

Commit 9f50d32 introduced a fix for FreeBSD /bin/sh misbehaviour
when dot-sourcing a file containing "return" statements outside of
any function, from a function in another shell script. That issue
affects FreeBSD 9.x, and is not present in the /bin/sh in FreeBSD
10.3 and later. Update the comment to clarify this.

The example from 9f50d32's commit message produces the expected output

bisect: always call setup_revisions after init_revisionsJeff King Thu, 16 Jun 2016 23:37:20 +0000 (19:37 -0400)

bisect: always call setup_revisions after init_revisions

init_revisions() initializes the rev_info struct to default
values, and setup_revisions() parses any command-line
arguments and finalizes the struct.

In e22278c (bisect: display first bad commit without forking
a new process, 2009-05-28), a show_diff_tree() was added
that calls the former but not the latter. It doesn't have
any arguments to parse, but it still should do the
finalizing step.

This may have caused other minor bugs over the years, but it
became much more prominent after fe37a9c (pretty: allow
tweaking tabwidth in --expand-tabs, 2016-03-29). That leaves
the expected tab width as "-1", rather than the true default
of "8". When we see a commit with tabs to be expanded, we
end up trying to add (size_t)-1 spaces to a strbuf, which
complains about the integer overflow.

The fix is easy: just call setup_revisions() with no
arguments.

pretty.c: support <direction>|(<negative number>) forms

%>|(num), %><|(num) and %<|(num), where num is a positive number, sets a
fixed column from the screen's left border. There is no way for us to
specifiy a column relative to the right border, which is useful when you
want to make use of all terminal space (on big screens). Use negative
num for that. Inspired by Go's array syntax (*).

didn't occur to me until I learned Go.
