Miscellaneous const changes and utilities

The list of remote refs in struct transport should be const, because
builtin-fetch will get confused if it changes.

The url in git_connect should be const (and work on a copy) instead of
requiring the caller to copy it.

match_refs doesn't modify the refspecs it gets.

get_fetch_map and get_remote_ref don't change the list they get.

Allow transport get_refs_list methods to modify the struct transport.

Add a function to copy a list of refs, when a function needs a mutable
copy of a const list.

Add a function to check the type of a ref, as per the code in connect.c

Show total transferred as part of throughput progress

Right now it is infeasible to offer to the user a reasonable concept
of when a clone will be complete as we aren't able to come up with
the final pack size until after we have actually transferred the
entire thing to the client.  However in many cases users can work
with a rough rule-of-thumb; for example it is somewhat well known
that git.git is about 16 MiB today and that linux-2.6.git is over
120 MiB.

We now show the total amount of data we have transferred over
the network as part of the throughput meter, organizing it in
"human friendly" terms like `ls -h` would do.  Users can glance at
this, see that the total transferred size is about 3 MiB, see the
throughput of X KiB/sec, and determine a reasonable figure of about
when the clone will be complete, assuming they know the rough size
of the source repository or are able to obtain it.

This is also a helpful indicator that there is progress being made
even if we stall on a very large object.  The thoughput meter may
remain relatively constant and the percentage complete and object
count won't be changing, but the total transferred will be increasing
as additional data is received for this object.

17 years agogitweb: Fix and simplify "split patch" detection
Jakub Narebski [Tue, 30 Oct 2007 00:35:05 +0000 (01:35 +0100)]
gitweb: Fix and simplify "split patch" detection

There are some cases when one line from "raw" git-diff output (raw
format) corresponds to more than one patch in the patchset git-diff
output; we call this situation "split patch". Old code misdetected
subsequent patches (for different files) with the same pre-image and
post-image as fragments of "split patch", leading to mislabeled
from-file/to-file diff header etc.

Old code used pre-image and post-image SHA-1 identifier ('from_id' and
'to_id') to check if current patch corresponds to old raw diff format
line, to find if one difftree raw line coresponds to more than one
patch in the patch format.  Now we use post-image filename for that.
This assumes that post-image filename alone can be used to identify
difftree raw line.  In the case this changes (which is unlikely
considering current diff engine) we can add 'from_id' and 'to_id'
to detect "patch splitting" together with 'to_file'.

Because old code got pre-image and post-image SHA-1 identifier for the
patch from the "index" line in extended diff header, diff header had
to be buffered.  New code takes post-image filename from "git diff"
header, which is first line of a patch; this allows to simplify
git_patchset_body code.  A side effect of resigning diff header
buffering is that there is always "diff extended_header" div, even
if extended diff header is empty.

Alternate solution would be to check when git splits patches, and do
not check if parsed info from current patch corresponds to current or
next raw diff format output line.  Git splits patches only for 'T'
(typechange) status filepair, and there always two patches
corresponding to one raw diff line.  It was not used because it would
tie gitweb code to minute details of git diff output.

While at it, use newly introduced parsed_difftree_line wrapper
subroutine in git_difftree_body.

17 years agoAdd a simple option parser.
Pierre Habouzit [Sun, 14 Oct 2007 23:35:37 +0000 (01:35 +0200)]
Add a simple option parser.

The option parser takes argc, argv, an array of struct option
and a usage string.  Each of the struct option elements in the array
describes a valid option, its type and a pointer to the location where the
value is written.  The entry point is parse_options(), which scans through
the given argv, and matches each option there against the list of valid
options.  During the scan, argv is rewritten to only contain the
non-option command line arguments and the number of these is returned.

Aggregation of single switches is allowed:
  -rC0 is the same as -r -C 0 (supposing that -C wants an arg).

Every long option automatically support the option with the same name,
prefixed with 'no-' to unset the switch. It assumes that initial value for
strings are "NULL" and for integers is "0".

Long options are supported either with '=' or without:
  --some-option=foo is the same as --some-option foo

17 years agouse only the $PATH for exec'ing git commands
Scott R Parish [Sun, 28 Oct 2007 11:17:20 +0000 (04:17 -0700)]
use only the $PATH for exec'ing git commands

We need to correctly set up $PATH for non-c based git commands.
Since we already do this, we can just use that $PATH and execvp,
instead of looping over the paths with execve.

This patch adds a setup_path() function to exec_cmd.c, which sets
the $PATH order correctly for our search order. execv_git_cmd() is
stripped down to setting up argv and calling execvp(). git.c's
