add the capability for index-pack to read from a stream

This patch only adds the streaming capability to index-pack.  Although
the code is different it has the exact same functionality as before to
make sure nothing broke.

This is in preparation for receiving packs over the net, parse them on
the fly, fix them up if they are "thin" packs, and keep the resulting
pack instead of exploding it into loose objects.  But such functionality
should come separately.

One immediate advantage of this patch is that index-pack can now deal
with packs up to 4GB in size even on 32-bit architectures since the pack
is not entirely mmap()'d all at once anymore.

18 years agoindex-pack: compare only the first 20-bytes of the key.
Nicolas Pitre [Tue, 17 Oct 2006 20:23:26 +0000 (16:23 -0400)]
index-pack: compare only the first 20-bytes of the key.

The "union delta_base" is a strange beast.  It is a 20-byte
binary blob key to search a binary searchable deltas[] array,
each element of which uses it to represent its base object with
either a full 20-byte SHA-1 or an offset in the pack.  Which
representation is used is determined by another field of the
deltas[] array element, obj->type, so there is no room for
confusion, as long as we make sure we compare the keys for the
same type only with appropriate length.  The code compared the
full union with memcmp().

When storing the in-pack offset, the union was first cleared
before storing an unsigned long, so comparison worked fine.

On 64-bit architectures, however, the union typically is 24-byte
long; the code did not clear the remaining 4-byte alignment
padding when storing a full 20-byte SHA-1 representation.  Using
memcmp() to compare the whole union was wrong.

This fixes the comparison to look at the first 20-bytes of the
union, regardless of the architecture.  As long as ulong is
smaller than 20-bytes this works fine.

introduce delta objects with offset to base

This adds a new object, namely OBJ_OFS_DELTA, renames OBJ_DELTA to
OBJ_REF_DELTA to better make the distinction between those two delta
objects, and adds support for the handling of those new delta objects
in sha1_file.c only.

The OBJ_OFS_DELTA contains a relative offset from the delta object's
position in a pack instead of the 20-byte SHA1 reference to identify
the base object.  Since the base is likely to be not so far away, the
relative offset is more likely to have a smaller encoding on average
than an absolute offset.  And for those delta objects the base must
always be stored first because there is no way to know the distance of
later objects when streaming a pack.  Hence this relative offset is
always meant to be negative.

The offset encoding is slightly denser than the one used for object
size -- credits to <linux@horizon.com> (whoever this is) for bringing
it to my attention.

This allows for pack size reduction between 3.2% (Linux-2.6) to over 5%
(linux-historic).  Runtime pack access should be faster too since delta
replay does skip a search in the pack index for each delta in a chain.

many cleanups to sha1_file.c

Those cleanups are mainly to set the table for the support of deltas
with base objects referenced by offsets instead of sha1.  This means
that many pack lookup functions are converted to take a pack/offset
tuple instead of a sha1.

This eliminates many struct pack_entry usages since this structure
carried redundent information in many cases, and it increased stack
footprint needlessly for a couple recursively called functions that used

In the process, packed_object_info_detail() has been reorganized as well
so to look much saner and more amenable to deltas with offset support.

Finally the appropriate adjustments have been made to functions that

* project/branch       shortlog of branch
* project/branch:file  file in branch, blob_plain view
* project/branch:dir/  directory listing of dir in branch, tree view

The following shortcuts works (see explanation below):

* project/branch:      directory listing of branch, main tree view
* project/:file        file in HEAD (raw)
* project/:dir/        directory listing of dir in HEAD
* project/:            directory listing of project's HEAD

We use ':' as separator between branch (ref) name and file name
(pathname) because valid branch (ref) name cannot have ':' inside.
This limit applies to branch name only. This allow for hierarchical
branches e.g. topic branch 'topic/subtopic', separate remotes
tracking branches e.g. 'refs/remotes/origin/HEAD', and discriminate
between head (branch) and tag with the same name.

Empty branch should be interpreted as HEAD.

If pathname (the part after ':') ends with '/', we assume that pathname
is name of directory, and we want to show contents of said directory
using "tree" view. If pathname is empty, it is equivalent to '/' (top
directory).

If pathname (the part after ':') does not end with '/', we assume that
pathname is name of file, and we show contents of said file using
"blob_plain" view.

Pathname is stripped of leading '/', so we can use ':/' to separate
branch from pathname. The rationale behind support for PATH_INFO based
URLs was to support project web pages for small projects: just create
an html branch and then use an URL like
  http://nowhere.com/gitweb.cgi/project.git/html:/index.html
The ':/' syntax allow for working links between .html files served
in such way, e.g. <a href="main.html"> link inside "index.html"
would get

upload-archive: monitor child communication even more carefully.

The current code works like this: if others flags than POLLIN is
raised we assume that (a) something bad happened and the child died or
(b) the child has closed the pipe because it had no more data to send.

For the latter case, we assume wrongly that one call to
process_input() will empty the pipe. Indeed it reads only 16Ko of data
by call and the the pipe capacity can be larger than that (on current
Linux kernel, it is 65536 bytes). Therefore the child can write 32ko
of data, for example, and close the pipe. After that poll will return
POLLIN _and_ POLLHUP and the parent will read only 16ko of data.

This patch forces the parent to empty the pipe as soon as POLLIN is
raised and even if POLLHUP or something else is raised too.

Moreover, some implementations of poll might return POLLRDNORM flag
even if it is non standard.

apply --unidiff-zero: loosen sanity checks for --unidiff=0 patches

In "git-apply", we have a few sanity checks and heuristics that
expects that the patch fed to us is a unified diff with at least
one line of context.

 * When there is no leading context line in a hunk, the hunk
   must apply at the beginning of the preimage.  Similarly, no
   trailing context means that the hunk is anchored at the end.

 * We learn a patch deletes the file from a hunk that has no
   resulting line (i.e. all lines are prefixed with '-') if it
   has not otherwise been known if the patch deletes the file.
   Similarly, no old line means the file is being created.

And we declare an error condition when the file created by a
creation patch already exists, and/or when a deletion patch
still leaves content in the file.

These sanity checks are good safety measures, but breaks down
when people feed a diff generated with --unified=0.  This was
recently noticed first by Matthew Wilcox and Gerrit Pape.

This adds a new flag, --unified-zero, to allow bypassing these
checks.  If you are in control of the patch generation process,
you should not use --unified=0 patch and fix it up with this
flag; rather you should try work with a patch with context.  But
if all you have to work with is a patch without context, this
flag may come handy as the last resort.

Fix git-am safety checks

An earlier commit cbd64af added a check that prevents "git-am"
to run without its standard input connected to a terminal while
resuming operation.  This was to catch a user error to try
feeding a new patch from its standard input while recovery.

The assumption of the check was that it is an indication that a
new patch is being fed if the standard input is not connected to
a terminal.  It is however not quite correct (the standard input
can be /dev/null if the user knows the operation does not need
any input, for example).  This broke t3403 when the test was run
with its standard input connected to /dev/null.

When git-am is given an explicit command such as --skip, there
is no reason to insist that the standard input is a terminal; we
are not going to read a new patch anyway.

problem with t3403-rebase-skip test.
