* [JGIT PATCH 2/2] Add getPatchText functions to obtain the plain-text version of a patch
From: Shawn O. Pearce @ 2008-12-13 2:42 UTC (permalink / raw)
To: Robin Rosenberg; +Cc: git
In-Reply-To: <1229136146-15359-1-git-send-email-spearce@spearce.org>
The conversion from byte[] to String is performed one line at a time,
in case the patch is a character encoding conversion patch for the
file. For simplicity we currently assume UTF-8 still as the default
encoding for any content, but eventually we should support using the
.gitattributes encoding property when performing this conversion.

* [JGIT PATCH 1/2] Add raw buffer fetch methods to FileHeader, HunkHeader
From: Shawn O. Pearce @ 2008-12-13 2:42 UTC (permalink / raw)

These permit application level code to read back the patch
script, for example to slice it up and output parts into a

Two last-minute patches. While using this code in Gerrit 2 I
realized I forgot to add a way to get the script back after its
been parsed by the library. :-)

First, from the new description [^[:print:][:space:]], or even
[^[:print:]] (whichever we choose) you can see that those characters
we are showing using C (\r, \v, \b,...) + octal (in older gitweb) or
hex (in never gitweb) escapes would be invisible otherwise, or do
the strange things like \b aka backspace character.
Sidenote: There is probably one exception we want to add, namely not
escape '\r' at the end of line, to be able to deal better with DOS
line endings (\r\n).
Second, and that is I think reason we started to escape control
characters like \014 or ^L i.e. FORM FEED (FF) character (e.g. in
COPYING file), or \033 or ^[ i.e. ESCAPE (\e) character (e.g. commit
20a3847d) is that they are not allowed in XML, which means that they
are not allowed in XHTML, which means that if they are on the page,
and MIME-type is 'application/xml+html' forcing strict XML/XHTML mode
validating browsers would not display the page because it is not valid
XHTML. Mozilla 1.17.2 did this, and it would not show page; I don't
know how it works with more modern browsers.

Erm, branching is not ordinarily useful? I think you're Doing It Wrong
(TM) then, since branching is a Big Thing (also TM) in DVC, not using
branches would be a bit like only using the first 4 gears in a car;
sure, it's possible, but you're missing all that extra power!

I'll agree with you that the git-scm site is in fact, a site, and as
such cannot easily be accessed.

It was aimed at addition to Linux, but someone might think it goes better in
GIT instead, and the GIT list is more narrowly focused on the right people to
review it.

Okay. I do mention tags. How they're stored in the database is irrelevant.
As far as most users need be concerned, a tag is a symbolic representation of
a particular commit in the tree; a particular state of the source tree.
Think of symbolic links as an analogy. Most users just need to know that a
symlink represents the location of another part of the VFS tree; actually most
users will just think of them as a pointer to the name of a file, if even that
much. The fact that, say, ReiserFS tail packs them because they tend to be
small, or that AFS symlinks have weird properties that encode mountpoints is
irrelevant to most users. You don't need to know that to use them.
Yes, GIT's database has blob objects, tree objects, commit objects and tag
objects; but as far as the normal user is concerned, it stores files, lists of
files (directories or, more probably, folders), commits and tags. The
physical low-level stuff is completely irrelevant.
There is one exception to that: commit IDs. These are public-facing as it
were. GIT waves them in your face, and you have to use them occasionally, so
it's useful to say a bit about them.

I didn't see that when googling for stuff. I have four issues with what's on
this website, though I could perhaps, as you point out, fix three of them
myself:
(1) It really needs a pictorial representation of the virtual GIT tree. How
GIT actually stores its data is irrelevant to people trying to use GIT
rather than trying to modify GIT. It would help those trying to use GIT
if you can help them visualise what they're dealing with. It doesn't
have to be complex.
See the attached FIG file for examples. Try running it through:
fig2dev -L pdf <in.fig >out.pdf
(2) In my document I've tried to thread a worked example through, so that if
you go through all the steps, they'll work in order. I'm not sure I've
been entirely successful, though.
(3) You put some non-basic stuff in the basic section (branching - this isn't
ordinarily useful, IMHO), but you miss other stuff out ('git rm' for
example).
(4) It needs to be installed with GIT in a form that can easily be cut and
pasted from (maybe this is the case).
I like the videos, though not all of them work, and a number of sections say
things like:
github
repoorcz
whatever that means.

That looks good. But I'm wondering why do we need to filter at all?
Is it a security concern? It is just description.

But we can expect it to work someday when savannah updates their git
version, or we can bug them to upgrade if the fix is in official git
release.

Quite a lot. Most notably the section I have on publishing changes by GIT
tree. It's taken a lot of experimentation to work out how to do it, and I'm
sure it can be done better. I hadn't managed to find anywhere on the web
describing how to do it that I could follow, and no-one that I asked was really
willing to help me set it up.
I have a number of crib sheets that I've cobbled together to note how to do
things that I can cut and paste from, so I turned them into a document.

* [JGIT PATCH 12/12 v2] Add support for parsing "diff --cc" style patches
From: Shawn O. Pearce @ 2008-12-12 23:19 UTC (permalink / raw)
To: Robin Rosenberg; +Cc: git
In-Reply-To: <1229119558-1293-13-git-send-email-spearce@spearce.org>
Even though the diff --cc format used by Git is only meant to be
read by humans, JGit needs to be able to parse these to get the
patch metadata so it can be shown in a user interface to facilitate
code review processes.
Patches are parsed into the specialized CombinedFileHeader and
CombinedHunkHeader classes, where the old image information is
augmented with additional fields for the arbitrary number of parents
that can appear in such patches. These cost more in terms of memory,
but "diff --cc" style patches tend to occur very infrequently as
they only occur during a merge conflict resolution.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

v2 is necessary because of the CombinedFileHeader glitch
in an earlier series.

* [JGIT PATCH 15/15 v2] Treat "diff --combined" the same as "diff --cc"

According to the git diff manual page these two formats
share the same file structure, so we can parse them with
the same function.

Dammit, that wasn't added until 12/12 of the final series.
A new 12/12 v2 will be sent in a minute.

I didn't consider using find_unique_abbrev(). I used the same format
that 'git stash drop' uses. There is enough room for a 20-char branch
name without overflowing an 80-char line (unless you're deleting a
remote branch). I kind of like the exactness of the full sha1 in this
case.

Actually, I'm more worried about line wrapping with a long branch name
than a short branch name being dominated by the 40-char sha1. I'd even
consider dropping the the word "branch " from the "Deleted branch ..."
message since the user already knows that a branch is being deleted.
So, this word-wrapping argument holds weight with me.
We read left to right and the sha1 is delimited by parenthesis, so I'm
not sure if the sha1 is dominating the line to the extent that it would
cause confusion.
For comparison:
$ git stash drop
Dropped refs/stash@{0} (a8381dd3d3ea4e7bc83c2bfe7d1c27fa180632ee)
compared to:
$ git branch -d my_branch_name
Deleted branch my_branch_name (ca26e31d5442f3d1ef8ae1cb69970fb31ed4b841).
or
$ git branch -d my_branch_name
Deleted branch my_branch_name (ca26e31d).
or
$ git branch -d my_branch_name
Deleted my_branch_name (ca26e31d5442f3d1ef8ae1cb69970fb31ed4b841).
But since the longest branch that has been merged in the git history
was 40 characters, maybe it does make sense to abbreviate the sha1.

Deleted branch my_branch_name (was ca26e31d).
I don't find it confusing (obviously) without the addition of "was ", but
I too haven't been a new user in a while.

* [PATCH] "git svn clone" fails when tags have illegal url characters in them.
From: Jerry Seutter @ 2008-12-12 22:46 UTC (permalink / raw)
To: git
Found a repository with a tag that had a hash (#) mark in the tag name.
The svn repository was available via WebDAV. "git svn clone <url>" would
generate an invalid url when trying to fetch the tag, causing a server
400 result on the other end of the connection.
The fix is to escape the url correctly. This is a quick and dirty
hack that copies two functions from earlier in the file - only the last
line modified in the commit is important.

A full summary of all of the commits appears below, along with the
final diffstat relative to the current master branch. 41 commits
and 6,151 lines of code in 3 days. Yikes.

I checked this, via this simple Perl script:
#!/usr/bin/perl
use charnames ":full";
my $c = ord("\N{ZWNJ}");
printf "oct=%o dec=%d hex=%x\n", $c, $c, $c;
"\N{ZWNJ}" =~ /[[:cntrl:]]/ and print "is [:cntrl:]";
And the answer was:
oct=20014 dex=8204 hex=200c
is [:cntrl:]
'ZERO WIDTH NON-JOINER' _is_ control character... We probably should
use [^[:print:][:space:]] instead of [[:cntrl:]] here.

Which can be seen from the fact that gitweb uses octal escapes,
instead of hex escapes...

* [JGIT PATCH 11/12] Add a test for delta binary patch parsing and fix a bug in it

To: Robin Rosenberg; +Cc: git
In-Reply-To: <1229119558-1293-11-git-send-email-spearce@spearce.org>
We had the wrong header code in this case, so we didn't parse
the length correctly for delta style binary hunks. Without a
test case for it we never noticed the problem.
