I would like to announce three git documents I have written which
others (primarily on #git) have thought to be very useful, and so I
would like to share them with the wider community.
Commit Often, Perfect Later, Publish Once: Git Best Practices
----------------------------------------------------------------------
http://sethrobertson.github.com/GitBestPractices
This first document covers a variety of topics, providing references
and recommendations for using git. These best practices have been
built up through decades of professional software management and
development, years of git usage, and countless hours helping people on
#git.
Table of Contents:
Do read about git On Sausage Making
Do commit early and often Do keep up to date
Don't panic Do periodic maintenance
Do backups Do enforce Standards
Don't change published history Do use useful tools
Do choose a workflow Do integrate with external tools
Do divide work into repositories Miscellaneous "Do"s
Do make useful commit messages Miscellaneous "Don't"s
On undoing, fixing, or removing commits or mistakes in git
----------------------------------------------------------------------
http://sethrobertson.github.com/GitFixUm
This next document covers the process of recovering from mistakes made
either while or when using git. It is a choose-your-own-adventure(1)
style document which asks a series of questions to try and understand
exactly what you did and what you want to do. Currently it provides
twenty different solutions to various problems I have seen people
have. This was primarily developed to stop answering the same
questions over and over again in #git, and worse, providing the wrong
answers when questioners either failed to provide critical information
or totally misunderstood what was going on.
Post-Production Editing using Git
----------------------------------------------------------------------
http://sethrobertson.github.com/GitPostProduction
This most recent document covers the topic of how to use git to make
your commits appear like they were made perfectly to the outside
world. Doing so is something which is required by some projects, is
recommended in gitworkflows(7) and the best practices document (On
Sausage Making), and is a major feature of git. However, I have not
found good documentation on exactly how to use git to accomplish this.
The git-rebase man page is quite extensive, but also fairly confusing
to the uninitiated.
I would appreciate comments, suggestions, or contributions for all
three documents.

I have only read the first of the three so far, but it looks very nice.
I did notice a few things which were worth commenting on (I'll quote
directly from the page in question below).

Resets and rebases record the commits in the reflog (at the very least
in the HEAD reflog), and should generally not be the cause of dangling
commits (the objects should usually expire in the same "git gc" that
expires the reflog entries). I suspect a more common cause is deleting
branches, which leaves no reflog (the commits may be in the HEAD reflog
if they were ever checked out, though).
It's somewhat minor; the overall advice ("do not worry about dangling
commits") holds. But it might be worth pointing out that the method for
recovering an accidentally deleted branch is usually:
1. look in the HEAD reflog
2. if you can't find it there, try dangling commits
> [section Do make useful commit messages]
This talks about formatting, but not about content. I have long wanted
to write a nice essay on what should go into a good commit message, but
when I've tried it ends up very specific to the project, the type of
commit, and the individual change. I wonder if anybody knows of
something good you could link to.

This is a nice overview of the motivation, but I think it misses one
of the main reasons we clean up patches in git.git: code review. When
you publish patches, you have several audiences. One of those audiences
is the end user who will compile release v1.5. They only care about the
end result of the patches. Another is people bisecting, who care that
everything intermediate builds and is reasonable; you can satisfy that
by checking each commit against a test suite. Another is people reading
the logs later to find out what happened; it's OK for them to see that a
bug was in the initial version, and then fixed 5 minutes later.
But yet another audience is reviewers who will read your changes and
decide they should be applied, rejected, or re-worked. For those people,
it is much harder to review a series that introduces a bug in patch 1,
but fixes it in patch 5. The reviewer may also notice the bug, take time
thinking about and writing an analysis, and then get frustrated to find
that their work was wasted when they get to patch 5.
The alternative is that they stop thinking about individual patches and
consider the whole series (e.g., when they see patch 1 has a bug, stop
reading and look through the other patches for a fix). But that makes
review much harder, because you have to think about a much larger series
of changes.
By cleaning up patches into single, logical changes that build on one
another, and which don't individually regress (i.e., they are always
moving towards some desirable common endpoint), the author is writing a
chronological story not of what happened, but what _should_ happen, with
the intent that the audience (i.e., reviewers) are convinced that the
change is the right thing to do.
I really liked your movie analogy. Patch series are really just
documentaries about a change, arranged for greatest impact on the
viewer. :)

Most people shouldn't be using "--aggressive". Unless you have an
existing pack that is poorly packed (e.g., because you did a
fast-import that did not do much delta searching), you are not going to
see much benefit, and it will take a lot longer. Basically the three
levels of "gc" are:
1. git gc --auto; if there are too many loose objects, they will all
go into a new incremental pack. If there are already too many
packs, all of the existing packs will get re-packed together.
If we are making an incremental pack, this is by far the fastest,
because the speed is independent of the existing history. If we
pack everything together, it should be more or less the same as (2)
below.
2. git gc; this packs everything into a single pack. It does not use
high window and depth parameters, but more importantly, it reuses
existing deltas. That makes the delta compression phase _much_
faster, and it often makes the writing phase faster (because for
older objects, we are primarily streaming them right out of the
existing pack). On a big repo, though, it does do a lot of I/O,
because it has to rewrite the whole pack.
3. git gc --aggressive; this is often way slower than the above
because we throw out all of the existing deltas and recompute them
from scratch. The higher window parameter means it will spend a bit
more time computing, and it may end up with a smaller pack.
In practical applications, I would expect (2) to achieve similar results to (3). If
that isn't the case, then I think we should be tuning up the default
window and depth parameters for non-aggressive "git gc" a bit.

It might help to qualify "big" here. To some people, 10,000 files,
50,000 commits, and a 200M packfile is big. But that's a fraction of
linux-2.6, which most people use. I think big here is probably getting
into 100K-200K files (where the time to stat() files becomes noticeable,
commits are probably not relevant (because git is usually good at only
looking at recent bits of history for most operations), and packfiles
above 1G or so start to get cumbersome (mostly because of the I/O on a
full repack; but then you should consider marking a pack as .keep).
But those numbers are just pulled out of a hat based on the last few
years. Your OS, your hardware, and your expectations make a huge
difference in what seems reasonable.
Your config recommendations seem mostly related to relieving memory
pressure for packing (at the expense of making the pack a lot slower).
Dropping --aggressive from your gc might help a lot with that, too. It
might be worth noting that you should only start twiddling these options
if you are running out of memory during a repack. They will not affect
git performance for day-to-day commands.
I don't think you should need to adjust core.packedGitWindowSize or
core.packedGitLimit at all. Those files are mmap'd, so it is up to the
OS to be reasonable about faulting in or releasing the memory. The main
motivation of pack windows is not memory _usage_, but rather getting a
large contiguous chunk of the address space. mmap-ing a 4G packfile on a
32-bit system just doesn't work. But the defaults are set to reasonable
values for each architecture.

To: Seth Robertson; +Cc: git
Just a few I noticed that are dubious to be in a document that is meant to
describe "best practices".
"Do commit early and often"
---------------------------
* "Personally ... history of this repository!". That looks somewhat out
of place when you are trying to document "best practices".
"Don't panic"
-------------
* As we never "auto-stash", anything that is on stash is by definition
what the user deliberately placed, just like a commit on a branch that
the user may have forgotten. So it is strange to count it as one of the
three places that "lost" commit may be hiding. If you make it four and
add "a branch you might have forgotten" to the mix, it would make a bit
more sense, though.
* The example command line for gitk passes --all and also everything from
"log -g" output, which should be OK for toy history, but wouldn't be
such a good idea when you can expect tons of data from "log -g".
Doesn't "gitk" itself accept -g these days?
* Lost and found
Why "git ls-tree -r"? Doesn't "git show" work eqully well?
Also, the name of the hash we happen to use to produce the "object name"
is "SHA-1", so either of these two are fine, but do not say "SHA"
(throughout the document).
"On Sausage Making"
-------------------
* The desription of "downside" shows a bias against efforts to strive for
useful history, and also shows ignorance of the true motivation behind
such discipline. It is _not_ blame or ego. It is all about leaving a
history others can later use to understand _why_ the code became the way
it is now, to make it less likely for others to break it.
If I were writing this, I would either remove that one paragraph
altogether, or tone it down dramatically. There is a short-term
downside that you would be spending time on perfecting the history
instead of advancing the tip of the branch, especially when you know the
tree at the tip of the perfected history will be identical to the tip of
the messy history you currently have. If you plan to leave the project
in a month or so and will never look back, that is totally wasted effort
as maintaining the result will be other people's problem. But if you
are planning to be involved in the project for a longer haul, the time
and effort is worth spending to make less-than-useful history into
useful one.
"Do keep up to date"
--------------------
* You explained in "Do choose a workflow" section that different workflows
suite different projects. It would read better to rephrase this
paragraph in which you are admitting that not everybody agrees with your
"pull --rebase". Instead of saying "but they should agree with me", it
would be more useful to say in what workflow and the workflow elements
such as "pull --rebase" you advocate in this section are suited (you do
not have to say in what other workflow they are inappropriate).
I stopped reading at this point, but will look at the rest some other day.
Thanks for a fun reading.

improved the document and made me think and experiment.

My understanding is that if a commit gets packed, it sticks around for
a few weeks longer than the reflog since the clock gets reset when it
gets evicted from a pack.

I'd certainly like to see such a thing. I did touch on the subject
further when I started talking about integration with bug tracking
systems.

This is a nice overview of the motivation, but I think it misses one
of the main reasons we clean up patches in git.git: code review.
Well, I said "change review" instead of "code review". I added the
word "code" specifically, but I'll stick some wording on why it is
important to code review. I already touched on people who wanted to
bisect.
By cleaning up patches into single, logical changes that build on one
another, and which don't individually regress (i.e., they are always
moving towards some desirable common endpoint), the author is writing a
chronological story not of what happened, but what _should_ happen, with
the intent that the audience (i.e., reviewers) are convinced that the
change is the right thing to do.
I'll add this paragraph as well.

Most people shouldn't be using "--aggressive".
I'll add `git gc` as an intermediate stage and take wording from the
manual to run `git gc --aggressive` every few hundred changesets.
I suppose it all depends on your definition of the period in periodic
maintenance.

It might help to qualify "big" here. ... I think big here is
probably getting into 100K-200K files (where the time to stat()

But those numbers are just pulled out of a hat based on the last few
years. Your OS, your hardware, and your expectations make a huge
difference in what seems reasonable.
That was why I didn't mention any specific limits. However, since you
were kind enough to do provide some, I will include them. I will also
add that my suggested configuration values are only needed if you are
experiencing memory pressure on packing.
Your config recommendations seem mostly related to relieving memory
pressure for packing (at the expense of making the pack a lot slower).
Very true, that was the problem I was running into. I will
specifically make that comment. I'll make a wild recommendation
about sizing these variables, which I'd certainly accept corrections
to or advice on. Specifically the next sentence:
----------------------------------------------------------------------
My gut tells me that sizing ("deltaCacheSize" + "windowMemory" +
min("core.bigFileThreshold[512m]", TheSizeOfTheLargestObject)) *
"threads" to be around *half* the amount of RAM you can dedicate to
running `git gc` will optimize your packing experience, but I will be
the first to admit that made up that formula based on a very few
samples and it could be drastically wrong.
------------------------------------------------------------------
I don't think you should need to adjust core.packedGitWindowSize or
core.packedGitLimit at all.
Well, certainly git takes up a ton (specifically double or just over
1GB additional) more RAM during gc with them unset, and caused some
limited swapping of other processes (but no thrashing). However, the
real question is, did it take more time? It did, but the amount of
added time was about 3% and thus probably well under my test accuracy.

I do. That was the next bullet "misplaced". I also expand on this a
bit during the second document about finding and fixing mistakes.
* The example command line for gitk passes --all and also everything from
"log -g" output, which should be OK for toy history, but wouldn't be
such a good idea when you can expect tons of data from "log -g".
My reasoning is that the live/referenced history provides context.
Seeing a series of commits going back in time is nice and all, but
knowing that at some point it branched from some particular
still-referenced branch allows you to concentrate only on the commits
that were "lost" (abandoned/replaced/etc), lets you have a better idea
on whether those commits are relevant, and perhaps you will even see
similar commits nearby on a still referenced branch.
Yes, for projects with dozens of simultaneously active branches it may
cause information overload. Ideally there would be an easy way to
only have gitk show relevant branches without a lot of work. Right
now, the only way I can think of is to find the --contains of the
first referenced parent of the unreferenced commits and then pick the
closest named branch to display using some algorithm. I'll also
suggest using `git log -Sfoo -g` in addition to my current alternate
suggestion of looking at the reflog directly.
Anyway, someone managing dozens of branches should know what --all
does and that they can remove it.
Doesn't "gitk" itself accept -g these days?
My gitk (1.7.9.2) accepts -g but doesn't show the reflog.
* Lost and found
Why "git ls-tree -r"? Doesn't "git show" work eqully well?
I find the added information of ls-tree more useful since you can more
easily examine the contents/blobs of the tree.
git show | git ls-tree -r

I have included that last sentence in the argument for creating a
perfected history. I personally believe that there are many contexts
in which a perfected history is critical, but I also feel there are
many cases where it is entirely overkill, which is why I talk about
both sides of the issue. But I think it important enough that I made
it one of the three things I mention in the title of the document
(perfect later) *and* I wrote the third document describing how
someone might actually go about the process.

In the pull --rebase section, I spend one short paragraph talking
about why I think it is a good idea and four providing arguments
against it. In my opinion, it rebase should always be used when it is
possible, and I did specifically mark it as my opinion and that people
disagree with me. I think I did about as good as I can presenting the
negative side, but if you have more specific arguments against rebase,
I'll be happy to include them. Perhaps it will even change my stance
about using rebase.

You don't. You say "There are THREE places where "last" changes can be

I do not know if you have updated the version seen on the web since the
review comments, but I was merely suggesting that "what I recommend here
may not be desirable for some workflows" without spelling out what these
workflows are would be less helpful to readers than being more explicit,
i.e. "these suggestions are good for this and that workflows".
This section by nature of what is discussed is bound to be incomplete and
