got: don't search through ignored paths and files on commit

use GOT_IGNORE_GITCONFIG in regress fixes test_rebase_no_author_info when a valid ~/.gitconfig is found. ok stsp@

got commit: add flag to specify the author This adds a new flag, `got commit -A', that allows to specify the commit author but retains the "committer" (which is obtained as usual via GOT_AUTHOR, got.conf or git config.) with lots of help from and ok stsp

fix email address parsing we were both too strict and too lose. To avoid breaking got object parser (and to some extent ours too) we need to ensure that there aren't any line feeds, extra < or > and no trailing gibberish. The '@' is not actually required in the email. various tweaks and ok stsp

regress: use bs=1M for dd, not bs=1m; fixes -portable test failure on ubuntu GNU dd only accepts upper-case letters for the size units.

always show commit or tree IDs in diff header, in order to help 'got patch' The idea is that got patch can simply look for a line such as: commit - abcde1234567... to find the merge base commit ID to show in diff3 conflict markers. got log -p now displays commit IDs in its diff header, instead ofl tree or blob IDs. ok op@

use test(1) -eq and -ne to compare integers, and reduce quoting This brings the rest of the regression test scripts in line with patch.sh.

improve error message due to malformed `author' in got.conf tweak and ok stsp@

compress delta data from delta_cache directly into pack file

regress: provide a sed wrapper In order to portably handle the difference in how 'sed -i' works between *BSD and Linux, provide a wrapper to invoke the underying system sed(1) based on which OSTYPE is in use.

regress: use gdate/gln if on *BSD To minimise the amount of churn between the difference in date(1) and ln(n) semantics, use gdate and gln from coreutils.

regress: fix test failures using ln(1) GNU ln uses -T instead of -h for no-target-directory. OK thomas.adam

regress: fix test failures using date(1) This patch fixes test failures related the date(1) utility. In the long term we could add a wrapper function to detect valid options for date(1) and use the variant which works on the current OS. For now, this makes some tests pass and shows us where the problems are. OK thomas.adam

make 'got update' display the worktree's branch name upon success ok tracey

use the POSIX-compliant "date -u" command to return UTC time; ok stsp

add missing "return 1" to failure handling in the regress scripts ok stsp@

fix hang in commit regress test. ok stsp

add 'got commit -F' option to commit with a log message stored in a file To avoid accidents commit -F opens the prepared log message in an editor so it can be reviewed before the commit is created. For non-interactive use the -N option is required in addition to -F. ok millert@

use POSIX [s1 = s2] syntax instead of [s1 == s2]; patch by Ryo ONODERA

expand arguments in shell script since brace expansion is not in POSIX ok stsp

switch function declarations from Korn shell to Bourne/POSIX shell syntax ok stsp

add per-worktree got.conf(5) file in the .got directory; ok millert

add got.conf(5) configuration file ok tracey

add a -q option to tests for quiet output and use it for 'make regress' Previous default output remains when test cases are run individually. ok tracey

fix committing file additions from a work tree with a path prefix New files were added under the wrong tree in the repository if the work tree has a path prefix. Fix this problem and catch it in the existing commit_with_path_prefix regression test.
