lib/sh/make.sh: added echo_target

*{.sh,run}: use new begin_target instead of `echo_func; set_make_vars`

lib/sh/make.sh: added make target template

lib/sh/make.sh: added begin_target alias

bugfix: lib/sh/util.sh: rethrow*: only `return` if $e is actually nonzero, because rethrow is now being used as a catch-all in situations where there might not be an error

lib/sh/util.sh: prep_try: initialize $e to 0 to simplify error-handling coding

stderr_matches(): wrapper caller usage: added alternative usage when using `||`

lib/sh/util.sh: stderr_matches(): wrapper caller usage: documented usage for a negated condition (ie. prefixed w/ !)

lib/sh/util.sh: stderr_matches(): usage: split into wrapper usage and wrapper caller usage for clarity

fix: *{.sh,run}: stderr_matches() wrappers: usage: added `rethrow`

fix: *{.sh,run}: stderr_matches() wrappers: usage: added `rethrow`

fix: lib/sh/util.sh: stderr_matches(): usage: `rethrow` must be called right after stderr_matches(), to avoid calling running other commands if there is an error

fix: lib/sh/util.sh: stderr_matches(): when using $ignore_e, also set benign_error=1 to suppress the highlighting of the error

bugfix: lib/sh/db.sh: pg_schema_exists(): need to ignore benign error exit status from the "cannot create temporary relation in non-temporary schema" error

lib/sh/util.sh: stderr_matches(): supporting ignoring any benign error exit status associated with the error message being tested for

lib/sh/util.sh: stderr_matches(): usage: documented where any ignore_e statement would go

bugfix: lib/sh/util.sh: stderr_matches(): can't use `try` because this clears the exit status, which is needed for @PIPESTATUS to work. to support this, also need to avoid errexiting since @PIPESTATUS will be used instead.

lib/sh/util.sh: added dp(), which debug-prints a message

lib/sh/db.sh: psql(): $verbose_ok: renamed to $bypass_ok for clarity, because this applies only to the `--output /dev/fd/41` bypass (which when not possible, requires turning off verbose output

fix: lib/sh/db.sh: psql(): added $output_data switch analogous to what mysql() has. this causes query results of eg. void-returning functions to be correctly filtered by the logging mechanism, rather than output to stdout.

fix: lib/sh/db.sh: psql(): verbosity=0 (errors only) mode: use `SET client_min_messages = WARNING;` instead of NOTICE to hide verbose messages within psql as well

lib/sh/db.sh: psql(): replaced `test "$verbose_ok" && can_log` with bool var $verbose_

fix: lib/sh/db.sh: psql(): $verbose_: renamed to $verbose_ok for clarity

fix: lib/sh/util.sh: stdout_contains(): add another pipe_delay because the `grep` statement was sometimes getting printed before its filtered output

bugfix: lib/sh/util.sh: die_error_hidden(): min verbosity to display error should not be hardcoded

lib/sh/db.sh: psql(): "to see error details" msg: use new die_error_hidden()

lib/sh/util.sh: added die_error_hidden()

lib/sh/db.sh: psql(): "to see error details" msg: use new log_hint()

lib/sh/util.sh: added log_hint(), whose msg is only displayed if not a benign error

bugfix: lib/sh/db.sh: psql(): "to see error details" msg: also don't print it for benign errors ($benign_error)

lib/sh/db.sh: psql(): on error, display message describing how to see error details (prepend `vb=2` to the command)

bugfix: lib/sh/util.sh: log_err(): don't override verbosity manually, as this will not set log_level or PS4. instead, use new log! , which sets these correctly.

lib/sh/util.sh: added log! , which force-displays next log message

lib/sh/util.sh: save_e: made it idempotent so that it also works if save_e was already called

lib/sh/util.sh: save_e: made it idempotent so that it also works if save_e was already called

lib/sh/util.sh: rethrow: documented why can't use `(exit "$e")` (bash bug that prevents errexit)

lib/sh/util.sh: added enter_top_dir and use it in in_top_dir

fix: lib/sh/util.sh: commands run inside $(...): need to run with log++ so that these aren't normally debug-printed

lib/sh/util.sh: added pv(), which debug-prints var(s)

lib/sh/util.sh: added wildcard.()

lib/sh/util.sh: added wildcard/()

lib/sh/util.sh: added esc_args()

lib/sh/util.sh: added is_callable()

lib/sh/util.sh: stderr_matches(): inline the stderr_matches alias to avoid needing to quote stderr_matches as "stderr_matches" in the most common use case (with pattern as a prefix env var)

bugfix: lib/sh/util.sh: stderr_matches(): when passing `pattern=...` as a prefix env var, must be invoked as `"stderr_matches"` to avoid the env var applying to the prep_try portion of the stderr_matches alias

lib/sh/util.sh: stderr_matches(): documented that the purpose of not redirecting fd 2 back to fd 2 is to allow log-filtering out an otherwise-confusing benign error

lib/sh/util.sh: ignore_err_msg(): documented that unlike `|| true`, this suppresses only errors caused by a particular error message, rather than all error exit statuses

lib/sh/util.sh: stdout_contains(): usage: documented that this requires a `{ ... } 41>&1` wrapper

lib/sh/util.sh: stderr2stdout(): clarified that fd 2 is not redirected back to fd 2

bugfix: lib/sh/util.sh: stderr_matches(): need to avoid redirecting stderr and stdout to the same place, because this prevents redirecting stdout back to the original stdout after stderr has been filtered using |

lib/sh/util.sh: local_export_array: renamed to just export_array because this was a replacement for export, not local_export

lib/sh/util.sh: local_*array: don't need -a because that it's an array is autodetected by the ()

lib/sh/util.sh: stderr_matches(): actually don't need to declare PIPESTATUS_ in a separate command, because local does support arrays

lib/sh/util.sh: added local_export_array

fix: lib/sh/util.sh: local_array: clarified that this is only needed for older versions of bash (the lack of support for arrays has apparently been fixed)

lib/sh/util.sh: added local_array

fix: lib/sh/util.sh: stderr_matches(): usage: documented that now need to manually rethrow any command error, if applicable

*{.sh,run}: stderr_matches calls: don't need to wrap the command in `"try"` because stderr_matches now does this

fix: lib/sh/util.sh: `shopt -s lastpipe`: suppress error message if not supported

lib/sh/util.sh: ignore_err_msg(): use new stderr_matches alias, which includes prep_try (requires loading new aliases)

bugfix: lib/sh/util.sh: stderr_matches(): need to save PIPESTATUS and then use the saved var because it's reset after each cmd

lib/sh/util.sh: stderr_matches(): place exit status of cmd in $e for use with exception handling

lib/sh/util.sh: set `shopt -s lastpipe`, to allow setting vars in the last command of a pipeline

bugfix: lib/sh/util.sh: ignore_err_msg(): use `try` properly with prep_try and `"try"`

lib/sh/util.sh: added prep_try and use it in try alias. try: documented how to run it with a wrapper command.

lib/sh/db.sh: pg_dump(): ignore "No matching tables were found" error, using new ignore_err_msg()

lib/sh/util.sh: added ignore_err_msg()

lib/sh/db.sh: pg_schema_exists(): documented that `try` is used to suppress the error exit status

lib/sh/util.sh: stderr_matches(): usage: surrounded command in if statement to indicate what context it would usually be used in

lib/sh/make.sh: remaking alias: documented that you MUST use set_make_vars at the beginning of any function that uses this, so that $_remake is properly set to $remake and not left at its previous value

moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

fix: lib/sh/util.sh: verbosity_min(): usage: clarified that '' is a special value that causes $verbosity to be overwritten to ''

lib/sh/local.sh: public_schema_exists(): use a higher log_level for pg_schema_exists, to avoid all the verbose output involved in running the query

bugfix: lib/sh/local.sh: public_schema_exists(): can no longer use psql_script_vegbien for this, because using `SET search_path` (called by psql_script_vegbien) with a schema that does not exist no longer produces an error. instead, use new pg_schema_exists(), which uses a different command that does produce an error if the schema does not exist.

lib/sh/db.sh: added pg_require_schema()

lib/sh/util.sh: stderr2stdout(): documented that this redirects fd 2->1 and log_fd (but not back to 2)

bugfix: lib/sh/util.sh: stderr2stdout() use `command` before tee, which re-filters log_fd so that stderr itself is also filtered. this allows log-filtering out an otherwise-confusing benign error when using e.g. stderr_matches().

lib/sh/util.sh: added not(), for use in prefixing wrapped commands

lib/sh/db.sh: added pg_schema_exists()

lib/sh/util.sh: added stderr_matches()

lib/sh/util.sh: documented that fds 2x/3x should not be used because we use these, as opposed to 1x which is used by the shell internally

lib/sh/util.sh: added stdout_contains()

lib/sh/util.sh: added stderr2stdout()

fix: lib/sh/db.sh: pg_table_exists(): usage: documented that $table is actually required for this function

lib/sh/util.sh: import_vars: don't overwrite vars that are already defined, to allow the caller to specify their own values for the vars to create. this requires callers that rely on the overwriting functionality to reverse the order in which they run use_* commands, so that the higher-precedence use_* is applied first and the other one as the default values for the first.

lib/sh/db.sh: pg_table_exists(): use `SELECT NULL` instead of `SELECT *` to avoid a long column list cluttering up the log output

lib/sh/db.sh: added pg_table_exists()

lib/sh/util.sh: already_exists_msg(): added instructions on how to force-remake when the file already exists (prepend `rm=1` to the command)

bugfix: lib/sh/make.sh: $remake: need to explicitly propagate this to invoked commands if it was set from $rm

lib/sh/db.sh: mk_select(): usage: documented that this also takes a $limit/$n param

lib/sh/db.sh: limit(): also support using $n as the limit param, since this var name is used by other parts of the import process

lib/sh/db.sh: limit(): usage: documented that this also need a $limit param

lib/sh/local.sh: psql(): also accept $public as the $schema param, since this is used by a lot of import scripts

lib/sh/util.sh: added require_dot_script()

bugfix: lib/sh/util.sh: $top_script: use @BASH_SOURCE instead of $0, because this is also defined for .-scripts

bugfix: lib/sh/util.sh: is_dot_script(): need to subtract 1 from ${#BASH_LINENO[@]}, because this is the array length rather than the index of the last element as in Perl

lib/sh/util.sh: added is_dot_script()

bugfix: lib/sh/util.sh: alias_append(): need to enclose $(alias) call in "" because its result may contain separator chars (i.e. whitespace) that will be parsed incorrectly. this appears to only be a bug when runscripts are run as shell-includes, with a leading ".".

bugfix: lib/sh/local.sh: psql(): $is_root: use `` around case statement instead of $(), because it contains an embedded unbalanced )

bugfix: lib/sh/local.sh: psql(): don't default the connection vars using use_local if running as the postgres user. in that case, connection must happen via a socket, with server="", and as the user running the command (postgres), with user="".
