The select command was fixed to check the validity of the user's + input more strenuously. + +b. A bug was fixed that prevented `time' from timing commands correctly + when supplied as an argument to `bash -c'. + +c. A fix was made to the mail checking code to keep from adding the same + mail file to the list of files to check multiple times when parsing + $MAILPATH. + +d. Fixed an off-by-one error in the tilde expansion library. + +e. When using the compound array assignment syntax, the old value of + the array is cleared before assigning the new value. + +f. Fixed a bug that could cause a core dump when a trap handler was reset + to the default in the trap command associated with that signal. + +g. Fixed a bug in the locale code that occurred when assigning a value + to LC_ALL. + +h. A change was made to the parser so that words of the form xxx=(...) + are not considered compound assignment statements unless there are + characters before the `='. + +i. A fix was made to the command tracing code to correctly quote each + word of output. + +j. Some changes were made to the bash-specific autoconf tests to make them + more portable. + +k. Completion of words with globbing characters now correctly quotes the + result. + +l. The directory /var/spool/mail is now preferred to /usr/spool/mail when + configure is deciding on the default mail directory. + +m. The brace completion code was fixed to not quote the `{' and `}'. + +n. Some fixes were made to make $RANDOM more random in subshells. + +o. System-specific changes were made to configure for: SVR4.2 + +p. Changes were made so that completion of words containing globbing chars + substitutes the result only if a single filename was matched. + +q. The window size is now recomputed after a job is stopped with SIGTSTP if + the user has set `checkwinsize' with `shopt'. + +r. When doing substring expansion, out-of-range substring specifiers now + cause nothing to be substituted rather than an expansion error. + +s. A fix was made so that you can no longer trap `SIGEXIT' or `SIGDEBUG' -- + only `EXIT' and `DEBUG' are accepted. + +t. The display of trapped signals now uses the signal number if signals + for which bash does not know the name are trapped. + +u. A fix was made so that `bash -r' does not turn on restricted mode until + after the startup files are executed. + +v. A bug was fixed that occasionally caused a core dump when a variable + found in the temporary environment of export/declare/readonly had a + null value. + +w. A bug that occasionally caused unallocated memory to be passed to free() + when doing arithmetic substitution was fixed. + +x. A bug that caused a buffer overrun when expanding a prompt string + containing `\w' and ${#PWD} exceeded PATH_MAX was fixed. + +y. A problem with the completion code that occasionally caused it to + refer to a character before the beginning of the readline line buffer + was fixed. + +z. A bug was fixed so that the `read' builtin restarts reads when + interrupted by signals other than SIGINT. + +aa. Fixed a bug that caused a command to be freed twice when there was + an evaluation error in the `eval' command. + +2. Changes to Readline + +a. Added a missing `extern' to a declaration in readline.h that kept + readline from compiling cleanly on some systems. + +b. The history file is now opened with mode 0600 when it is written for + better security. + +c. Changes were made to the SIGWINCH handling code so that prompt redisplay + is done better. + +d. ^G now interrupts incremental searches correctly. + +e. A bug that caused a core dump when the set of characters to be quoted + when completing words was empty was fixed. + +------------------------------------------------------------------------------ This document details the changes between this version, bash-2.01-release, and the previous version, bash-2.01-beta2. |
