DESCRIPTION
-----------
visualizing the commit graph, showing information related to each commit, and
the files in the trees of each revision.
-Historically, gitk was the first repository browser. It's written in tcl/tk
-and started off in a separate repository but was later merged into the main
-Git repository.
-
OPTIONS
-------
-To control which revisions to show, the command takes options applicable to
-the 'git rev-list' command (see linkgit:git-rev-list[1]).
-This manual page describes only the most
-frequently used options.
--n <number>::
---max-count=<number>::
+To control which revisions to show, gitk supports most options
+applicable to the 'git rev-list' command. It also supports a few
+options applicable to the 'git diff-*' commands to control how the
+changes each commit introduces are shown. Finally, it supports some
+gitk-specific options.
+
+gitk generally only understands options with arguments in the
+'sticked' form (see linkgit:gitcli[7]) due to limitations in the
+command line parser.
+
+rev-list options and arguments
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This manual page describes only the most frequently used options. See
+linkgit:git-rev-list[1] for a complete list.
+
+--all::
+
+ Show all refs (branches, tags, etc.).
- Limits the number of commits to show.
+--branches[=<pattern>]::
+--tags[=<pattern>]::
+--remotes[=<pattern>]::
+
+ Pretend as if all the branches (tags, remote branches, resp.)
+ are listed on the command line as '<commit>'. If '<pattern>'
+ is given, limit refs to ones matching given shell glob. If
+ pattern lacks '?', '{asterisk}', or '[', '/{asterisk}' at the
+ end is implied.
--since=<date>::
Show commits older than a specific date.
---all::
+--date-order::
- Show all branches.
+ Sort commits by date when possible.
--merge::
that modify the conflicted files and do not exist on all the heads
being merged.
---argscmd=<command>::
- Command to be run each time gitk has to determine the list of
- <revs> to show. The command is expected to print on its standard
- output a list of additional revs to be shown, one per line.
- Use this instead of explicitly specifying <revs> if the set of
- commits to show may vary between refreshes.
+--left-right::
---select-commit=<ref>::
+ Mark which side of a symmetric diff a commit is reachable
+ from. Commits from the left side are prefixed with a `<`
+ symbol and those from the right with a `>` symbol.
- Automatically select the specified commit after loading the graph.
- Default behavior is equivalent to specifying '--select-commit=HEAD'.
+--full-history::
+
+ When filtering history with '<path>...', does not prune some
+ history. (See "History simplification" in linkgit:git-log[1]
+ for a more detailed explanation.)
+
+--simplify-merges::
-<revs>::
+ Additional option to '--full-history' to remove some needless
+ merges from the resulting history, as there are no selected
+ commits contributing to this merge. (See "History
+ simplification" in linkgit:git-log[1] for a more detailed
+ explanation.)
+
+--ancestry-path::
+
+ When given a range of commits to display
+ (e.g. 'commit1..commit2' or 'commit2 {caret}commit1'), only
+ display commits that exist directly on the ancestry chain
+ between the 'commit1' and 'commit2', i.e. commits that are
+ both descendants of 'commit1', and ancestors of 'commit2'.
+ (See "History simplification" in linkgit:git-log[1] for a more
+ detailed explanation.)
+
+<revision range>::
Limit the revisions to show. This can be either a single revision
meaning show from the given revision and back, or it can be a range in
avoid ambiguity with respect to revision names use "--" to separate the paths
from any preceding options.
+gitk-specific options
+~~~~~~~~~~~~~~~~~~~~~
+
+--argscmd=<command>::
+
+ Command to be run each time gitk has to determine the revision
+ range to show. The command is expected to print on its
+ standard output a list of additional revisions to be shown,
+ one per line. Use this instead of explicitly specifying a
+ '<revision range>' if the set of commits to show may vary

+Subject: pack corruption post-mortem
+Abstract: Recovering a corrupted object when no good copy is available.
+Content-type: text/asciidoc
+
+How to recover an object from scratch
+=====================================
+
+I was recently presented with a repository with a corrupted packfile,
+and was asked if the data was recoverable. This post-mortem describes
+the steps I took to investigate and fix the problem. I thought others
+might find the process interesting, and it might help somebody in the
+same situation.
+
+********************************
+Note: In this case, no good copy of the repository was available. For
+the much easier case where you can get the corrupted object from
+elsewhere, see link:recover-corrupted-blob-object.html[this howto].
+********************************
+
+I started with an fsck, which found a problem with exactly one object
+(I've used $pack and $obj below to keep the output readable, and also
+because I'll refer to them later):
+
+-----------
+ $ git fsck
+ error: $pack SHA1 checksum mismatch
+ error: index CRC mismatch for object $obj from $pack at offset 51653873
+ error: inflate: data stream error (incorrect data check)
+ error: cannot unpack $obj from $pack at offset 51653873
+-----------
+
+The pack checksum failing means a byte is munged somewhere, and it is
+presumably in the object mentioned (since both the index checksum and
+zlib were failing).
+
+Reading the zlib source code, I found that "incorrect data check" means
+that the adler-32 checksum at the end of the zlib data did not match the
+inflated data. So stepping the data through zlib would not help, as it
+did not fail until the very end, when we realize the crc does not match.
+The problematic bytes could be anywhere in the object data.
+
+The first thing I did was pull the broken data out of the packfile. I
+needed to know how big the object was, which I found out with:
+
+------------
+ $ git show-index <$idx | cut -d' ' -f1 | sort -n | grep -A1 51653873
+ 51653873
+ 51664736
+------------
+
+Show-index gives us the list of objects and their offsets. We throw away
+everything but the offsets, and then sort them so that our interesting
+offset (which we got from the fsck output above) is followed immediately
+by the offset of the next object. Now we know that the object data is
+10863 bytes long, and we can grab it with:
+
+------------
+ dd if=$pack of=object bs=1 skip=51653873 count=10863
+------------
+
+I inspected a hexdump of the data, looking for any obvious bogosity
+(e.g., a 4K run of zeroes would be a good sign of filesystem
+corruption). But everything looked pretty reasonable.
+
+Note that the "object" file isn't fit for feeding straight to zlib; it
+has the git packed object header, which is variable-length. We want to
+strip that off so we can start playing with the zlib data directly. You
+can either work your way through it manually (the format is described in
+link:../technical/pack-format.html[Documentation/technical/pack-format.txt]),
+or you can walk through it in a debugger. I did the latter, creating a
+valid pack like:
+
+------------
+ # pack magic and version
+ printf 'PACK\0\0\0\2' >tmp.pack
+ # pack has one object
+ printf '\0\0\0\1' >>tmp.pack
+ # now add our object data
+ cat object >>tmp.pack
+ # and then append the pack trailer
+ /path/to/git.git/test-sha1 -b <tmp.pack >trailer
+ cat trailer >>tmp.pack
+------------
+
+and then running "git index-pack tmp.pack" in the debugger (stop at
+unpack_raw_entry). Doing this, I found that there were 3 bytes of header
+(and the header itself had a sane type and size). So I stripped those
+off with:
+
+------------
+ dd if=object of=zlib bs=1 skip=3
+------------
+
+I ran the result through zlib's inflate using a custom C program. And
+while it did report the error, I did get the right number of output
+bytes (i.e., it matched git's size header that we decoded above). But
+feeding the result back to "git hash-object" didn't produce the same
+sha1. So there were some wrong bytes, but I didn't know which. The file
+happened to be C source code, so I hoped I could notice something
+obviously wrong with it, but I didn't. I even got it to compile!
+
+I also tried comparing it to other versions of the same path in the
+repository, hoping that there would be some part of the diff that didn't
+make sense. Unfortunately, this happened to be the only revision of this
+particular file in the repository, so I had nothing to compare against.
+
+So I took a different approach. Working under the guess that the
+corruption was limited to a single byte, I wrote a program to munge each
+byte individually, and try inflating the result. Since the object was
+only 10K compressed, that worked out to about 2.5M attempts, which took
+a few minutes.
+
+The program I used is here:
+
+----------------------------------------------
+#include <stdio.h>
+#include <unistd.h>
+#include <string.h>
+#include <signal.h>
+#include <zlib.h>
+
+static int try_zlib(unsigned char *buf, int len)
+{
+ /* make this absurdly large so we don't have to loop */
+ static unsigned char out[1024*1024];
+ z_stream z;
+ int ret;
+
+ memset(&z, 0, sizeof(z));
+ inflateInit(&z);
+
+ z.next_in = buf;
+ z.avail_in = len;
+ z.next_out = out;
+ z.avail_out = sizeof(out);
+
+ ret = inflate(&z, 0);
+ inflateEnd(&z);
+ return ret >= 0;
+}
+
+/* eye candy */
+static int counter = 0;
+static void progress(int sig)
+{
+ fprintf(stderr, "\r%d", counter);
+ alarm(1);
+}
+
+int main(void)
+{
+ /* oversized so we can read the whole buffer in */
+ unsigned char buf[1024*1024];
+ int len;
+ unsigned i, j;
+
+ signal(SIGALRM, progress);
+ alarm(1);
+
+ len = read(0, buf, sizeof(buf));
+ for (i = 0; i < len; i++) {
+ unsigned char c = buf[i];
+ for (j = 0; j <= 0xff; j++) {
+ buf[i] = j;
+
+ counter++;
+ if (try_zlib(buf, len))
+ printf("i=%d, j=%x\n", i, j);
+ }
+ buf[i] = c;
+ }
+
+ alarm(0);
+ fprintf(stderr, "\n");
+ return 0;
+}
+----------------------------------------------
+
+I compiled and ran with:
+
+-------
+ gcc -Wall -Werror -O3 munge.c -o munge -lz
+ ./munge <zlib
+-------
+
+
+There were a few false positives early on (if you write "no data" in the
+zlib header, zlib thinks it's just fine :) ). But I got a hit about
+halfway through:
+
+-------
+ i=5642, j=c7
+-------
+
+I let it run to completion, and got a few more hits at the end (where it
+was munging the crc to match our broken data). So there was a good
+chance this middle hit was the source of the problem.
+
+I confirmed by tweaking the byte in a hex editor, zlib inflating the
+result (no errors!), and then piping the output into "git hash-object",
+which reported the sha1 of the broken object. Success!
+
+I fixed the packfile itself with:
+
+-------
+ chmod +w $pack
+ printf '\xc7' | dd of=$pack bs=1 seek=51659518 conv=notrunc
+ chmod -w $pack
+-------
+
+The `\xc7` comes from the replacement byte our "munge" program found.
+The offset 51659518 is derived by taking the original object offset
+(51653873), adding the replacement offset found by "munge" (5642), and
+then adding back in the 3 bytes of git header we stripped.
+
+After that, "git fsck" ran clean.
+
+As for the corruption itself, I was lucky that it was indeed a single
+byte. In fact, it turned out to be a single bit. The byte 0xc7 was
+corrupted to 0xc5. So presumably it was caused by faulty hardware, or a
+cosmic ray.
+
+And the aborted attempt to look at the inflated output to see what was
+wrong? I could have looked forever and never found it. Here's the diff
+between what the corrupted data inflates to, versus the real data:
+
+--------------
+ - cp = strtok (arg, "+");
+ + cp = strtok (arg, ".");
+--------------
+
+It tweaked one byte and still ended up as valid, readable C that just
+happened to do something totally different! One takeaway is that on a
+less unlucky day, looking at the zlib output might have actually been
+helpful, as most random changes would actually break the C code.
+
+But more importantly, git's hashing and checksumming noticed a problem
+that easily could have gone undetected in another system. The result
+still compiled, but would have caused an interesting bug (that would
+have been blamed on some random commit).
