*{.sh,run}: use standard WARNING syntax for warning labels

*{.sh,run}: use standard WARNING syntax for warning labels

fix: lib/sh/util.sh: verbosity_compat(): documented that this should not be run until right before executing an external command, so that it doesn't mess up the logging mechanism

bugfix: lib/sh/util.sh: functions called by pst(): commented out/removed logging calls that would have caused infinite recursion when pst()'ing a logging function

lib/sh/util.sh: echo_func(): get call context before wrapper(s), which is more useful for debugging. this uses skip_stack_frames()'s lookahead=1 mode.

fix: lib/sh/util.sh: skip_stack_frames() callers: updated for new skip_stack_frames rather than get_stack_frame behavior

lib/sh/util.sh: skip_stack_frames(): added lookahead support, which looks at entry after current to deterine whether to skip current. this is useful for skipping wrappers, by looking at the calling function's name.

fix: lib/sh/util.sh: skip_stack_frames(): for new skip_stack_frames rather than get_stack_frame behavior, stack frames must be skipped in the caller to preserve the stack frame pointer

lib/sh/util.sh: get_stack_frame_after(): renamed to skip_stack_frames() for clarity

lib/sh/util.sh: added skip_stack_frame_in_caller, unskip_stack_frame_in_caller

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

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

lib/sh/util.sh: terminal: moved before errors so it can be used by it

lib/sh/util.sh: errors, debugging: moved after datatype sections so their functions can use these

bugfix: lib/sh/util.sh: canon_rel_path() stub: proper no-op requires passing through original path

lib/sh/util.sh: canon_rel_path(): fall back to original path if can't resolve, instead of errexiting

bugfix: lib/sh/util.sh: canon_rel_path(): don't re-localize $path because this clears it

lib/sh/util.sh: canon_rel_path(): import $1 to $path before function body, so that the function body can be moved to a nested function

lib/sh/util.sh: added canon_rel_path() stub for use by debugging functions

lib/sh/util.sh: moved func_loc() to before debugging section so it can be used by debugging functions

bugfix: lib/sh/util.sh: command__exec(): need to restore $verbosity before calling die_e

fix: lib/sh/local.sh: $sync_remote_url: need $USER so user can be overridden when running as root

lib/sh/util.sh: echo_vars(): merge repeated flags so there aren't flags in between the vars (which is also not valid declare syntax)

lib/sh/db.sh: pg_cmd(): log vars on same line to avoid clutter

lib/sh/util.sh: echo_vars(): put all the vars on the same line so they don't clutter up the call graph generated at the default verbosity

bugfix: lib/sh/archives.sh: compress(): don't include dir prefix in zip archive

lib/sh/util.sh: cd(): use echo_run instead of a manual echo_cmd call

fix: lib/sh/util.sh: cd(): indent after running cd rather than before

lib/sh/util.sh: cd(): support rebasing path vars for the new dir

bugfix: lib/sh/archives.sh: compress(): need to use zip's path syntax to avoid the file in the archive being named "-"

lib/sh/archives.sh: added compress(), expand(), which handle compression of individual files

bugfix: lib/sh/util.sh: str2varname(): need to lowercase str because on case-insensitive filesystems, paths sometimes canonicalize to a different capitalization than the original

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

bugfix: lib/sh/util.sh: die(): need stub since this is invoked before it's defined

bugfix: lib/sh/util.sh: setup_log_fd(): don't change $log_fd to stdlog until stdlog is set up, to avoid "Bad file descriptor" errors

lib/sh/util.sh: func_override(), copy_func(): added echo_func to facilitate debugging

bugfix: lib/sh/util.sh: stubs: log++ alias also needs to be moved to stub section

lib/sh/sync.sh: db_snapshot(): before backing up, trim bloated temp files (eg. from rolled back changes)

bugfix: lib/sh/db.sh: pg_dump(): need use_pg to import $pg_database before checking for existence of $database

lib/sh/util.sh: import_vars: documented that it's idempotent

bugfix: benign_does_not_exist_error(): removed ignore_e=3, because this exit status is also used for other errors

fix: lib/sh/db.sh: benign_does_not_exist_error(): use benign_error=1, which is now supported properly by stderr_matches()

bugfix: lib/sh/util.sh: stderr_matches(): support $benign_error properly, by handling exit status logging in this func instead

bugfix: lib/sh/db.sh: pg_schema_exists(): also need to benignify "does not exist" error if returns false

bugfix: lib/sh/util.sh: stderr_matches(): need to separately display errors that were incorrectly suppressed due to $benign_error

bugfix: lib/sh/util.sh: is_err(): rethrow must be inverted (rethrow->false if error)

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

lib/sh/local.sh: public_schema_exists(): moved to lib/sh/db.sh since this no longer depends on BIEN-specific configurations

bugfix: lib/sh/db.sh: public_schema_exists(): don't hide the function call tree so it's clear which function is running the psql commands

bugfix: lib/sh/db.sh: public_schema_exists(): don't hide the function call tree so it's clear which function is running the psql commands

fix: *{.sh,run}: stderr_matches() callers: usage: documented that they may require benign_error=1

fix: lib/sh/util.sh: stderr_matches(): usage: documented that this may require benign_error=1

bugfix: lib/sh/db.sh: pg_cmd(): updated for new echo_vars log_level

fix: lib/sh/db.sh: pg_schema_exists(): display the function name so it's clear which function is running the psql commands

fix: lib/sh/db.sh: pg_schema_exists(): don't use log++ because it hides the command that produces the benign error

bugfix: lib/sh/util.sh: highlight_log_msg(): when not can_highlight_log_msg, need to remove any surrounding formatting

fix: lib/sh/util.sh: die_error_hidden(): always log local vars at same log_level as echo_func

fix: *{.sh,run}: always log kw_params at same log_level as echo_func

lib/sh/util.sh: split_lines(): usage: matched up and synced different syntaxes

bugfix: lib/sh/util.sh: log_msg!(): split_lines does not support being invoked by wrapper; need to use `declare lines; wrapper "split_lines" str` instead

fix: lib/sh/util.sh: split_lines(): usage: documented different syntax for when using wrapper

bugfix: lib/sh/util.sh: die_error_hidden(): echo_func to assist debugging

bugfix: lib/sh/util.sh: split(): need to limit the effects of IFS to just the splitting, so it doesn't cause strange errors in other functions

bugfix: stderr2stdout(): fd 2 must be redirected back to fd 2, not log-filtered, in case there are other errors in addition to the benign error. this fixes a bug in pg_schema_exists(), where errors about the DB being down were not displayed because they were log-filtered out.

lib/sh/make.sh: set_make_vars: don't display make vars at verbosity 2 to avoid clutter

bugfix: lib/sh/make.sh: begin_target: don't echo_func twice

lib/sh/db.sh: pg_snapshot(): perform online backup if possible, to avoid needing to restart the server

lib/sh/db.sh: added pg_start_backup(), pg_stop_backup()

lib/sh/db.sh: psql(): only set redirs if can redirect

bugfix: psql(): when as_root is on, need to avoid redirections as these are not passed through by sudo

bugfix: lib/sh/db.sh: psql(): don't use `--file /dev/fd/40` when can't redirect

fix: lib/sh/db.sh: psql(): when using sudo with custom $stdin, raise error that this is not supported

lib/sh/db.sh: psql(): $data_bypasses_filter: renamed to $data2stdout for clarity

lib/sh/db.sh: psql(): $bypass_ok: renamed to $can_redir for clarity

lib/sh/util.sh: cmd2rel_path: use is_extern()

lib/sh/sync.sh: db_snapshot(): use `end_try` as specified in `try` usage

lib/sh/util.sh: try: usage: added location of finally block

lib/sh/sync.sh: upload(): always print the function and kw_params

bugfix: lib/sh/util.sh: type(): need to handle options before command name

lib/sh/util.sh: added 1st_non_opt()

lib/sh/util.sh: unalias(): use self_builtin, which is now defined before it

lib/sh/util.sh: unalias(): use self_builtin, which is now defined before it

bugfix: lib/sh/util.sh: commands: `type` calls: need to account for the fact that any alias is already expanded

lib/sh/util.sh: functions: moved before commands since commands are more complex

lib/sh/sync.sh: db_copy() and callers: pass args as rsync options

fix: lib/sh/sync.sh: db_copy(): need to exclude files which prevent tape backup

lib/sh/db.sh: added pg_ctl(), pg_snapshot()
