Raw Normal View History

Replaced last of old shell calls with their newer counterparts. This removed the need for p-string routines, so they were removed. Also removed alloc256/free256 and associated data structures. In removing calls, found instances in pwd & prefix commands and prompt handler where current directory name was assumed to be < 256 characters; recoded to use a flexible buffer size. Updated and expanded mmdebug.asm routines that perform error checking on memory management calls. Added macros ~NEW and ~DISPOSE that invoke either the real or debug routines. Fixed call to read $TERM variable's length to fix PR#81. Removed echo of data when setting value of $< in expandvars (expand.asm). The characters are echoed as they are typed and do not need to be reprinted on stdout after carriage-return is typed. Added error checking to the various flavors of prefix (just like cd): - Verify 2nd parameter is a valid directory before setting. - Verify 1st parameter < 32 before displaying or setting.

Changes for gsh version 2.0d8: Fixed several mutual exclusion problems, including a particularly nasty one that would cause gsh to loop forever inside the memory manager. (You could identify this one by the "BRA (-23)" at the bottom of the infinite loop.) Fixed the string vector print routine to properly handle all numbers of entries in the hash table. Previously, it would always print duplicate entries if there were < 6 commands hashed, and would sometimes print duplicates (depending on previous contents of an internal table) for other numbers of commands. gsh would wait on background processes started from an exec file (executed, not sourced). Now the exec file does not wait on the process, but the background process is not associated with the parent shell after the exec file terminates. Made gsh globbing work more like csh: if none of the requested patterns are found, print "No match" and exit. At startup, if /etc/glogin, $HOME/glogin, or $HOME/gshrc does not exist, don't report a "file not found" error message. (PR#100)

This checkin contains only enough changes that gsh is able to assemble and link. However, it does not work yet and thus still needs work. The *.asm files have had the following common changes: - 'keep' lines were eliminated - the 'mcopy' now takes the macro from the /obj/gno/bin/gsh directory. This is in anticipation of having the macro files generated from a single source file; there is a large amount of duplication. For the moment, the makefile merely copies the old macro files from the "M" directory to the /obj/gno/bin/gsh directory. - start each file with a dummy routine so that the source code winds up in the *.o rather than the *.root file. - added the 'setcom 60' directive; there were many source lines that were otherwise getting truncated. The makefile is a complete rewrite.

Major changes to gsh with this checkin: * When ~ is parsed and next character is a delimiter, make sure contents of expanded $HOME match the user's delimiter. * When wildcard patterns don't match, rather than terminating the command gsh now prints "No match: <pattern> ignored" and passes the command line minus the unmatched patterns on to be executed. * Modified echo command so it doesn't add a blank to the end. * Make "clear" and "source" built-ins non-forked commands. Unforking "source" allows prefixes to be set in files that are sourced. * Add loop to parse a single command (removing leading whitespace) before sending it off to be expanded and executed. Skip null lines and comments at this level. This allows later commands that depend upon variables set in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num" Also fixes problems seen when tab was first character of multiple lines. * Initialize environment variable flags at startup (for echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set flag when env var is set in upper or lower case (formerly, only worked with lower case). * Lots of places two-word addresses are incremented using inc, without checking for overflow into the high-order word. As these are discovered, they are changed to use adc on both words. See file UpdateLog for detailed list of changes.

doglob sta ptr ptr points to next
Replaced last of old shell calls with their newer counterparts. This removed the need for p-string routines, so they were removed. Also removed alloc256/free256 and associated data structures. In removing calls, found instances in pwd & prefix commands and prompt handler where current directory name was assumed to be < 256 characters; recoded to use a flexible buffer size. Updated and expanded mmdebug.asm routines that perform error checking on memory management calls. Added macros ~NEW and ~DISPOSE that invoke either the real or debug routines. Fixed call to read $TERM variable's length to fix PR#81. Removed echo of data when setting value of $< in expandvars (expand.asm). The characters are echoed as they are typed and do not need to be reprinted on stdout after carriage-return is typed. Added error checking to the various flavors of prefix (just like cd): - Verify 2nd parameter is a valid directory before setting. - Verify 1st parameter < 32 before displaying or setting.

Now the exec file does not wait on the process, but the background process is not associated with the parent shell after the exec file terminates. Made gsh globbing work more like csh: if none of the requested patterns are found, print "No match" and exit. At startup, if /etc/glogin, $HOME/glogin, or $HOME/gshrc does not exist, don't report a "file not found" error message. (PR#100)

Major changes to gsh with this checkin: * When ~ is parsed and next character is a delimiter, make sure contents of expanded $HOME match the user's delimiter. * When wildcard patterns don't match, rather than terminating the command gsh now prints "No match: <pattern> ignored" and passes the command line minus the unmatched patterns on to be executed. * Modified echo command so it doesn't add a blank to the end. * Make "clear" and "source" built-ins non-forked commands. Unforking "source" allows prefixes to be set in files that are sourced. * Add loop to parse a single command (removing leading whitespace) before sending it off to be expanded and executed. Skip null lines and comments at this level. This allows later commands that depend upon variables set in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num" Also fixes problems seen when tab was first character of multiple lines. * Initialize environment variable flags at startup (for echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set flag when env var is set in upper or lower case (formerly, only worked with lower case). * Lots of places two-word addresses are incremented using inc, without checking for overflow into the high-order word. As these are discovered, they are changed to use adc on both words. See file UpdateLog for detailed list of changes.

; Hello, boys and goils, velcome to Tim's Magik Shoppe
;
; Ok, here's the plan:
Replaced last of old shell calls with their newer counterparts. This removed the need for p-string routines, so they were removed. Also removed alloc256/free256 and associated data structures. In removing calls, found instances in pwd & prefix commands and prompt handler where current directory name was assumed to be < 256 characters; recoded to use a flexible buffer size. Updated and expanded mmdebug.asm routines that perform error checking on memory management calls. Added macros ~NEW and ~DISPOSE that invoke either the real or debug routines. Fixed call to read $TERM variable's length to fix PR#81. Removed echo of data when setting value of $< in expandvars (expand.asm). The characters are echoed as they are typed and do not need to be reprinted on stdout after carriage-return is typed. Added error checking to the various flavors of prefix (just like cd): - Verify 2nd parameter is a valid directory before setting. - Verify 1st parameter < 32 before displaying or setting.

Major changes to gsh with this checkin: * When ~ is parsed and next character is a delimiter, make sure contents of expanded $HOME match the user's delimiter. * When wildcard patterns don't match, rather than terminating the command gsh now prints "No match: <pattern> ignored" and passes the command line minus the unmatched patterns on to be executed. * Modified echo command so it doesn't add a blank to the end. * Make "clear" and "source" built-ins non-forked commands. Unforking "source" allows prefixes to be set in files that are sourced. * Add loop to parse a single command (removing leading whitespace) before sending it off to be expanded and executed. Skip null lines and comments at this level. This allows later commands that depend upon variables set in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num" Also fixes problems seen when tab was first character of multiple lines. * Initialize environment variable flags at startup (for echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set flag when env var is set in upper or lower case (formerly, only worked with lower case). * Lots of places two-word addresses are incremented using inc, without checking for overflow into the high-order word.

Replaced last of old shell calls with their newer counterparts. This removed the need for p-string routines, so they were removed. Also removed alloc256/free256 and associated data structures. In removing calls, found instances in pwd & prefix commands and prompt handler where current directory name was assumed to be < 256 characters; recoded to use a flexible buffer size. Updated and expanded mmdebug.asm routines that perform error checking on memory management calls. Added macros ~NEW and ~DISPOSE that invoke either the real or debug routines. Fixed call to read $TERM variable's length to fix PR#81. Removed echo of data when setting value of $< in expandvars (expand.asm). The characters are echoed as they are typed and do not need to be reprinted on stdout after carriage-return is typed.

Changes for gsh version 2.0d8: Fixed several mutual exclusion problems, including a particularly nasty one that would cause gsh to loop forever inside the memory manager. (You could identify this one by the "BRA (-23)" at the bottom of the infinite loop.) Fixed the string vector print routine to properly handle all numbers of entries in the hash table. Previously, it would always print duplicate entries if there were < 6 commands hashed, and would sometimes print duplicates (depending on previous contents of an internal table) for other numbers of commands. gsh would wait on background processes started from an exec file (executed, not sourced). Now the exec file does not wait on the process, but the background process is not associated with the parent shell after the exec file terminates. Made gsh globbing work more like csh: if none of the requested patterns are found, print "No match" and exit. At startup, if /etc/glogin, $HOME/glogin, or $HOME/gshrc does not exist, don't report a "file not found" error message. (PR#100)

Added startup protocol as requested by Devin Reed (PR#78) and Steve Reeves (PR#85, PR#86): For login shells (command line starts with '-'), If $PATH doesn't start with ':' or contain a space, change all ":" to " ". source /etc/glogin source $HOME/glogin $HOME/gshrc is sourced afterward for both login and non-login shells. Don't the print number of hashed commands (from "rehash") until all initialization is completed. Only pass exported environment variables to child processes, and prevent child processes from changing parent's environment. A null command followed by a redirection of stdout, for example > /tmp/list would cause an error message "<garbage> not found" due to incorrect setting of command buffer pointer. Filename completion did not work following ">&" or ">" without a trailing space. Entabbed all the asm files, saving more than 36,000 bytes.

Major changes to gsh with this checkin: * When ~ is parsed and next character is a delimiter, make sure contents of expanded $HOME match the user's delimiter. * When wildcard patterns don't match, rather than terminating the command gsh now prints "No match: <pattern> ignored" and passes the command line minus the unmatched patterns on to be executed. * Modified echo command so it doesn't add a blank to the end. * Make "clear" and "source" built-ins non-forked commands. Unforking "source" allows prefixes to be set in files that are sourced. * Add loop to parse a single command (removing leading whitespace) before sending it off to be expanded and executed. Skip null lines and comments at this level. This allows later commands that depend upon variables set in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num" Also fixes problems seen when tab was first character of multiple lines. * Initialize environment variable flags at startup (for echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set flag when env var is set in upper or lower case (formerly, only worked with lower case). * Lots of places two-word addresses are incremented using inc, without checking for overflow into the high-order word. As these are discovered, they are changed to use adc on both words. See file UpdateLog for detailed list of changes.

Changed many invocations from old shell interface routines (Read_Variable, Set_Variable, Export, etc.) to new ones (ReadVariableGS, SetGS, ExportGS, etc.) in many places; there are still a few more to change. This change removed the 256-character limit on strings retrieved by these routines, such as the value of environment variables. (PR # 9). At startup do not set $TERM to gnocon if it is already set. Removed the df command (from builtin.asm). Defined macro incad to increment a 4-byte address, checking for overflow; replaced instances of "inc ptr" with "incad ptr". Changed column offset table to use a 1-word rather than 1-byte entry. This resolves PR#14 (hash wouldn't print beyond first 256 filenames). Fixed defect in unalias (alias.asm) where the double quote portion of the scanner would look for a terminating single quote. This resolves PR#69. Changed default order for copying files in $PATH dirs into executable list, so earlier paths files are found first. Added environment variable flag $OLDPATHMODE to make gsh behave in the old (backwards order) way when necessary. Discard duplicate filenames when hashing. Fix PR#73: directory in $PATH with escaped space (\ ) is not searched.

In removing calls, found instances in pwd & prefix commands and prompt handler where current directory name was assumed to be < 256 characters; recoded to use a flexible buffer size. Updated and expanded mmdebug.asm routines that perform error checking on memory management calls. Added macros ~NEW and ~DISPOSE that invoke either the real or debug routines. Fixed call to read $TERM variable's length to fix PR#81. Removed echo of data when setting value of $< in expandvars (expand.asm). The characters are echoed as they are typed and do not need to be reprinted on stdout after carriage-return is typed. Added error checking to the various flavors of prefix (just like cd): - Verify 2nd parameter is a valid directory before setting. - Verify 1st parameter < 32 before displaying or setting.

Changes for gsh version 2.0d8: Fixed several mutual exclusion problems, including a particularly nasty one that would cause gsh to loop forever inside the memory manager. (You could identify this one by the "BRA (-23)" at the bottom of the infinite loop.) Fixed the string vector print routine to properly handle all numbers of entries in the hash table. Previously, it would always print duplicate entries if there were < 6 commands hashed, and would sometimes print duplicates (depending on previous contents of an internal table) for other numbers of commands. gsh would wait on background processes started from an exec file (executed, not sourced). Now the exec file does not wait on the process, but the background process is not associated with the parent shell after the exec file terminates. Made gsh globbing work more like csh: if none of the requested patterns are found, print "No match" and exit. At startup, if /etc/glogin, $HOME/glogin, or $HOME/gshrc does not exist, don't report a "file not found" error message. (PR#100)

Changed many invocations from old shell interface routines (Read_Variable, Set_Variable, Export, etc.) to new ones (ReadVariableGS, SetGS, ExportGS, etc.) in many places; there are still a few more to change. This change removed the 256-character limit on strings retrieved by these routines, such as the value of environment variables. (PR # 9). At startup do not set $TERM to gnocon if it is already set. Removed the df command (from builtin.asm). Defined macro incad to increment a 4-byte address, checking for overflow; replaced instances of "inc ptr" with "incad ptr". Changed column offset table to use a 1-word rather than 1-byte entry. This resolves PR#14 (hash wouldn't print beyond first 256 filenames). Fixed defect in unalias (alias.asm) where the double quote portion of the scanner would look for a terminating single quote. This resolves PR#69. Changed default order for copying files in $PATH dirs into executable list, so earlier paths files are found first. Added environment variable flag $OLDPATHMODE to make gsh behave in the old (backwards order) way when necessary. Discard duplicate filenames when hashing. Fix PR#73: directory in $PATH with escaped space (\ ) is not searched.

Don't the print number of hashed commands (from "rehash") until all initialization is completed.

A null command followed by a redirection of stdout, for example > /tmp/list would cause an error message "<garbage> not found" due to incorrect setting of command buffer pointer.

Unforking "source" allows prefixes to be set in files that are sourced. * Add loop to parse a single command (removing leading whitespace) before sending it off to be expanded and executed. Skip null lines and comments at this level. This allows later commands that depend upon variables set in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num" Also fixes problems seen when tab was first character of multiple lines. * Initialize environment variable flags at startup (for echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set flag when env var is set in upper or lower case (formerly, only worked with lower case). * Lots of places two-word addresses are incremented using inc, without checking for overflow into the high-order word. As these are discovered, they are changed to use adc on both words. See file UpdateLog for detailed list of changes.

Unforking "source" allows prefixes to be set in files that are sourced. * Add loop to parse a single command (removing leading whitespace) before sending it off to be expanded and executed. Skip null lines and comments at this level. This allows later commands that depend upon variables set in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num" Also fixes problems seen when tab was first character of multiple lines. * Initialize environment variable flags at startup (for echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set flag when env var is set in upper or lower case (formerly, only worked with lower case). * Lots of places two-word addresses are incremented using inc, without checking for overflow into the high-order word. As these are discovered, they are changed to use adc on both words. See file UpdateLog for detailed list of changes.

Changed many invocations from old shell interface routines (Read_Variable, Set_Variable, Export, etc.) to new ones (ReadVariableGS, SetGS, ExportGS, etc.) in many places; there are still a few more to change. This change removed the 256-character limit on strings retrieved by these routines, such as the value of environment variables. (PR # 9). At startup do not set $TERM to gnocon if it is already set. Removed the df command (from builtin.asm). Defined macro incad to increment a 4-byte address, checking for overflow; replaced instances of "inc ptr" with "incad ptr". Changed column offset table to use a 1-word rather than 1-byte entry. This resolves PR#14 (hash wouldn't print beyond first 256 filenames). Fixed defect in unalias (alias.asm) where the double quote portion of the scanner would look for a terminating single quote. This resolves PR#69. Changed default order for copying files in $PATH dirs into executable list, so earlier paths files are found first. Added environment variable flag $OLDPATHMODE to make gsh behave in the old (backwards order) way when necessary. Discard duplicate filenames when hashing. Fix PR#73: directory in $PATH with escaped space (\ ) is not searched.

Added startup protocol as requested by Devin Reed (PR#78) and Steve Reeves (PR#85, PR#86): For login shells (command line starts with '-'), If $PATH doesn't start with ':' or contain a space, change all ":" to " ". source /etc/glogin source $HOME/glogin $HOME/gshrc is sourced afterward for both login and non-login shells. Don't the print number of hashed commands (from "rehash") until all initialization is completed. Only pass exported environment variables to child processes, and prevent child processes from changing parent's environment. A null command followed by a redirection of stdout, for example > /tmp/list would cause an error message "<garbage> not found" due to incorrect setting of command buffer pointer. Filename completion did not work following ">&" or ">" without a trailing space. Entabbed all the asm files, saving more than 36,000 bytes.

stdinexpand jsr e_getbyte
Replaced last of old shell calls with their newer counterparts. This removed the need for p-string routines, so they were removed. Also removed alloc256/free256 and associated data structures. In removing calls, found instances in pwd & prefix commands and prompt handler where current directory name was assumed to be < 256 characters; recoded to use a flexible buffer size. Updated and expanded mmdebug.asm routines that perform error checking on memory management calls. Added macros ~NEW and ~DISPOSE that invoke either the real or debug routines. Fixed call to read $TERM variable's length to fix PR#81. Removed echo of data when setting value of $< in expandvars (expand.asm). The characters are echoed as they are typed and do not need to be reprinted on stdout after carriage-return is typed. Added error checking to the various flavors of prefix (just like cd): - Verify 2nd parameter is a valid directory before setting. - Verify 1st parameter < 32 before displaying or setting.

Major changes to gsh with this checkin: * When ~ is parsed and next character is a delimiter, make sure contents of expanded $HOME match the user's delimiter. * When wildcard patterns don't match, rather than terminating the command gsh now prints "No match: <pattern> ignored" and passes the command line minus the unmatched patterns on to be executed. * Modified echo command so it doesn't add a blank to the end. * Make "clear" and "source" built-ins non-forked commands. Unforking "source" allows prefixes to be set in files that are sourced. * Add loop to parse a single command (removing leading whitespace) before sending it off to be expanded and executed. Skip null lines and comments at this level. This allows later commands that depend upon variables set in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num" Also fixes problems seen when tab was first character of multiple lines. * Initialize environment variable flags at startup (for echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set flag when env var is set in upper or lower case (formerly, only worked with lower case). * Lots of places two-word addresses are incremented using inc, without checking for overflow into the high-order word. As these are discovered, they are changed to use adc on both words. See file UpdateLog for detailed list of changes.

Changed many invocations from old shell interface routines (Read_Variable, Set_Variable, Export, etc.) to new ones (ReadVariableGS, SetGS, ExportGS, etc.) in many places; there are still a few more to change. This change removed the 256-character limit on strings retrieved by these routines, such as the value of environment variables. (PR # 9). At startup do not set $TERM to gnocon if it is already set. Removed the df command (from builtin.asm). Defined macro incad to increment a 4-byte address, checking for overflow; replaced instances of "inc ptr" with "incad ptr". Changed column offset table to use a 1-word rather than 1-byte entry. This resolves PR#14 (hash wouldn't print beyond first 256 filenames). Fixed defect in unalias (alias.asm) where the double quote portion of the scanner would look for a terminating single quote. This resolves PR#69.

Changed many invocations from old shell interface routines (Read_Variable, Set_Variable, Export, etc.) to new ones (ReadVariableGS, SetGS, ExportGS, etc.) in many places; there are still a few more to change. This change removed the 256-character limit on strings retrieved by these routines, such as the value of environment variables. (PR # 9). At startup do not set $TERM to gnocon if it is already set. Removed the df command (from builtin.asm). Defined macro incad to increment a 4-byte address, checking for overflow; replaced instances of "inc ptr" with "incad ptr". Changed column offset table to use a 1-word rather than 1-byte entry. This resolves PR#14 (hash wouldn't print beyond first 256 filenames). Fixed defect in unalias (alias.asm) where the double quote portion of the scanner would look for a terminating single quote. This resolves PR#69. Changed default order for copying files in $PATH dirs into executable list, so earlier paths files are found first. Added environment variable flag $OLDPATHMODE to make gsh behave in the old (backwards order) way when necessary. Discard duplicate filenames when hashing. Fix PR#73: directory in $PATH with escaped space (\ ) is not searched.

Added startup protocol as requested by Devin Reed (PR#78) and Steve Reeves (PR#85, PR#86): For login shells (command line starts with '-'), If $PATH doesn't start with ':' or contain a space, change all ":" to " ". source /etc/glogin source $HOME/glogin $HOME/gshrc is sourced afterward for both login and non-login shells. Don't the print number of hashed commands (from "rehash") until all initialization is completed. Only pass exported environment variables to child processes, and prevent child processes from changing parent's environment. A null command followed by a redirection of stdout, for example > /tmp/list would cause an error message "<garbage> not found" due to incorrect setting of command buffer pointer. Filename completion did not work following ">&" or ">" without a trailing space. Entabbed all the asm files, saving more than 36,000 bytes.
