Linus Torvalds 9a8e35e987 Relative timestamps in git log
I noticed that I was looking at the kernel gitweb output at some point
rather than just do "git log", simply because I liked seeing the
simplified date-format, ie the "5 days ago" rather than a full date.

This adds infrastructure to do that for "git log" too. It does NOT add the
actual flag to enable it, though, so right now this patch is a no-op, but
it should now be easy to add a command line flag (and possibly a config
file option) to just turn on the "relative" date format.

The exact cut-off points when it switches from days to weeks etc are
totally arbitrary, but are picked somewhat to avoid the "1 weeks ago"
thing (by making it show "10 days ago" rather than "1 week", or "70
minutes ago" rather than "1 hour ago").

[jc: with minor fix and tweak around "month" and "week" area.]

Shawn Pearce e702496e43 Convert memcpy(a,b,20) to hashcpy(a,b).
This abstracts away the size of the hash values when copying them
from memory location to memory location, much as the introduction
of hashcmp abstracted away hash value comparsion.

A few call sites were using char* rather than unsigned char* so
I added the cast rather than open hashcpy to be void*.  This is a
reasonable tradeoff as most call sites already use unsigned char*
and the existing hashcmp is also declared to be unsigned char*.

[jc: Splitted the patch to "master" part, to be followed by a
 patch for merge-recursive.c which is not in "master" yet.

 Fixed the cast in the latter hunk to combine-diff.c which was
 wrong in the original.

 Also converted ones left-over in combine-diff.c, diff-lib.c and
 upload-pack.c ]

Rene Scharfe 7230e6d042 Add write_or_die(), a helper function
The little helper write_or_die() won't come back with bad news about
full disks or broken pipes.  It either succeeds or terminates the
program, making additional error handling unnecessary.

This patch adds the new function and uses it to replace two similar
ones (the one in tar-tree originally has been copied from cat-file
btw.).  I chose to add the fd parameter which both lacked to make
write_or_die() just as flexible as write() and thus suitable for
lib-ification.

There is a regression: error messages emitted by this function don't
show the program name, while the replaced two functions did.  That's
acceptable, I think; a lot of other functions do the same.

Junio C Hamano 40aaae88ad Better error message when we are unable to lock the index file
Most of the callers except the one in refs.c use the function to
update the index file.  Among the index writers, everybody
except write-tree dies if they cannot open it for writing.

This gives the function an extra argument, to tell it to die
when it cannot create a new file as the lockfile.

The only caller that does not have to die is write-tree, because
updating the index for the cache-tree part is optional and not
being able to do so does not affect the correctness.  I think we
do not have to be so careful and make the failure into die() the
same way as other callers, but that would be a different patch.

Linus Torvalds 93821bd97a sha1_file: add the ability to parse objects in "pack file format"
The pack-file format is slightly different from the traditional git
object format, in that it has a much denser binary header encoding.
The traditional format uses an ASCII string with type and length
information, which is somewhat wasteful.

A new object format starts with uncompressed binary header
followed by compressed payload -- this will allow us later to
copy the payload straight to packfiles.

Obviously they cannot be read by older versions of git, so for
now new object files are created with the traditional format.
core.legacyheaders configuration item, when set to false makes
the code write in new format for people to experiment with.

Johannes Schindelin 6d297f8137 Status update on merge-recursive in C
This is just an update for people being interested. Alex and me were
busy with that project for a few days now. While it has progressed nicely,
there are quite a couple TODOs in merge-recursive.c, just search for "TODO".

For impatient people: yes, it passes all the tests, and yes, according
to the evil test Alex did, it is faster than the Python script.

But no, it is not yet finished. Biggest points are:

- there are still three external calls
- in the end, it should not be necessary to write the index more than once
  (just before exiting)
- a lot of things can be refactored to make the code easier and shorter

BTW we cannot just plug in git-merge-tree yet, because git-merge-tree
does not handle renames at all.

This patch is meant for testing, and as such,

- it compile the program to git-merge-recur
- it adjusts the scripts and tests to use git-merge-recur instead of
  git-merge-recursive
- it provides "TEST", a script to execute the tests regarding -recursive
- it inlines the changes to read-cache.c (read_cache_from(), discard_cache()
  and refresh_cache_entry())

Linus Torvalds 2718ff098a Improve git-peek-remote
This makes git-peek-remote able to basically do everything that
git-ls-remote does (but obviously just for the native protocol, so no
http[s]: or rsync: support).

The default behaviour is the same, but you can now give a mixture of
"--refs", "--tags" and "--heads" flags, where "--refs" forces
git-peek-remote to only show real refs (ie none of the fakey tag lookups,
but also not the special pseudo-refs like HEAD and MERGE_HEAD).

The "--tags" and "--heads" flags respectively limit the output to just
regular tags and heads, of course.

You can still also ask to limit them by name too.

You can combine the flags, so

	git peek-remote --refs --tags .

will show all local _true_ tags, without the generated tag lookups
(compare the output without the "--refs" flag).

And "--tags --heads" will show both tags and heads, but will avoid (for
example) any special refs outside of the standard locations.

I'm also planning on adding a "--ignore-local" flag that allows us to ask
it to ignore any refs that we already have in the local tree, but that's
an independent thing.

All this is obviously gearing up to making "git fetch" cheaper.

Joachim B Haga 12f6c308d5 Make zlib compression level configurable, and change default.
With the change in default, "git add ." on kernel dir is about
twice as fast as before, with only minimal (0.5%) change in
object size. The speed difference is even more noticeable
when committing large files, which is now up to 8 times faster.

The configurability is through setting core.compression = [-1..9]
which maps to the zlib constants; -1 is the default, 0 is no
compression, and 1..9 are various speed/size tradeoffs, 9
being slowest.

	plain	- lines that appear in both old and new file (context)
	meta	- diff --git header and extended git diff headers
	frag	- @@ -n,m +l,k @@ lines (hunk header)
	old	- lines deleted from old file
	new	- lines added to new file

Linus Torvalds 855419f764 Add specialized object allocator
This creates a simple specialized object allocator for basic
objects.

This avoids wasting space with malloc overhead (metadata and
extra alignment), since the specialized allocator knows the
alignment, and that objects, once allocated, are never freed.

It also allows us to track some basic statistics about object
allocations. For example, for the mozilla import, it shows
object usage as follows:

     blobs:   627629 (14710 kB)
     trees:  1119035 (34969 kB)
   commits:   196423  (8440 kB)
      tags:     1336    (46 kB)

and the simpler allocator shaves off about 2.5% off the memory
footprint off a "git-rev-list --all --objects", and is a bit
faster too.

[ Side note: this concludes the series of "save memory in object storage".
  The thing is, there simply isn't much more to be saved on the objects.

  Doing "git-rev-list --all --objects" on the mozilla archive has a final
  total RSS of 131498 pages for me: that's about 513MB. Of that, the
  object overhead is now just 56MB, the rest is going somewhere else (put
  another way: the fact that this patch shaves off 2.5% of the total
  memory overhead, considering that objects are now not much more than 10%
  of the total shows how big the wasted space really was: this makes
  object allocations much more memory- and time-efficient).

  I haven't looked at where the rest is, but I suspect the bulk of it is
  just the pack-file loading. It may be that we should pack the tree
  objects separately from the blob objects: for git-rev-list --objects, we
  don't actually ever need to even look at the blobs, but since trees and
  blobs are interspersed in the pack-file, we end up not being dense in
  the tree accesses, so we end up looking at more pages than we strictly
  need to.

  So with a 535MB pack-file, it's entirely possible - even likely - that
  most of the remaining RSS is just the mmap of the pack-file itself. We
  don't need to map in _all_ of it, but we do end up mapping a fair
  amount. ]

Linus Torvalds 405e5b2fe0 Libify the index refresh logic
This cleans up and libifies the "git update-index --[really-]refresh"
functionality. This will be eventually required for eventually doing the
"commit" and "status" commands as built-ins.

It really just moves "refresh_index()" from update-index.c to
read-cache.c, but it also has to change the calling convention so that the
function uses a "unsigned int flags" argument instead of various static
flags variables for passing down the information about whether to be quiet
or not, and allow unmerged entries etc.

That actually cleans up update-index.c too, since it turns out that all
those flags were really specific to that one function of the index update,
so they shouldn't have had file-scope visibility even before.

Junio C Hamano 6858d49492 Merge part of 'js/fmt-patch' for RFC2822 dates into 'sp/reflog'
An earlier patch from Shawn Pearce dependes on a change that is
only in "next".  I do not want to make this series hostage to
the yet-to-graduate js/fmt-patch branch, but let's try fixing it
by merging the early parts of the branch to see what happens.

Right now, 'sp/reflog' will not be in "next" for now, so I won't
have to regret this -- if this merge causes problem down the road
merging I can always rebuild the topic branch ;-).

Linus Torvalds 8dcf39c46e Prevent bogus paths from being added to the index.
With this one, it's now a fatal error to try to add a pathname
that cannot be added with "git add", i.e.

	[torvalds@g5 git]$ git add .git/config
	fatal: unable to add .git/config to index

and

	[torvalds@g5 git]$ git add foo/../bar
	fatal: unable to add foo/../bar to index

instead of the old "Ignoring path xyz" warning that would end up
silently succeeding on any other paths.

Shawn Pearce 6de08ae688 Log ref updates to logs/refs/<ref>
If config parameter core.logAllRefUpdates is true or the log
file already exists then append a line to ".git/logs/refs/<ref>"
whenever git-update-ref <ref> is executed.  Each log line contains
the following information:

  oldsha1 <SP> newsha1 <SP> committer <LF>

where committer is the current user, date, time and timezone in
the standard GIT ident format.  If the caller is unable to append
to the log file then git-update-ref will fail without updating <ref>.

An optional message may be included in the log line with the -m flag.

Junio C Hamano 0660626caf binary diff: further updates.
This updates the user interface and generated diff data format.

 * "diff --binary" is used to signal that we want an e-mailable
   binary patch.  It implies --full-index and -p.

 * "apply --allow-binary-replacement" acquired a short synonym
   "apply --binary".

 * After the "GIT binary patch\n" header line there is a token
   to record which binary patch mechanism was used, so that we
   can extend it later.  Currently there are two mechanisms
   defined: "literal" and "delta".  The former records the
   deflated postimage and the latter records the deflated delta
   from the preimage to postimage.

   For purely implementation convenience, I added the deflated
   length after these "literal/delta" tokens (otherwise the
   decoding side needs to guess and reallocate the buffer while
   inflating).  Improvement patches are very welcomed.

Junio C Hamano 051308f6e9 binary patch.
This adds "binary patch" to the diff output and teaches apply
what to do with them.

On the diff generation side, traditionally, we said "Binary
files differ\n" without giving anything other than the preimage
and postimage object name on the index line.  This was good
enough for applying a patch generated from your own repository
(very useful while rebasing), because the postimage would be
available in such a case.  However, this was not useful when the
recipient of such a patch via e-mail were to apply it, even if
the preimage was available.

This patch allows the diff to generate "binary" patch when
operating under --full-index option.  The binary patch follows
the usual extended git diff headers, and looks like this:

	"GIT binary patch\n"
	<length byte><data>"\n"
	...
	"\n"

Each line is prefixed with a "length-byte", whose value is upper
or lowercase alphabet that encodes number of bytes that the data
on the line decodes to (1..52 -- 'A' means 1, 'B' means 2, ...,
'Z' means 26, 'a' means 27, ...).  <data> is 1 or more groups of
5-byte sequence, each of which encodes up to 4 bytes in base85
encoding.  Because 52 / 4 * 5 = 65 and we have the length byte,
an output line is capped to 66 characters.  The payload is the
same diff-delta as we use in the packfiles.

On the consumption side, git-apply now can decode and apply the
binary patch when --allow-binary-replacement is given, the diff
was generated with --full-index, and the receiving repository
has the preimage blob, which is the same condition as it always
required when accepting an "Binary files differ\n" patch.
