Bug ID: 63834
Summary: "a" , "i" command get error on mod_sed
Product: Apache httpd-2
Version: 2.4.41
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_sed
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Hello.
I want to add some new line to output HTML by using mod_sed.
I worte configuration file following,
---
OutputSed '/^HOGEHOGE$/aFUGAFUGA'
---
but this configuration get error on syntax check.
---
$ sudo /usr/local/apache2/bin/apachectl -t
AH00526: Syntax error on line 81 of /usr/local/apache2/conf/httpd.conf:
Failed to compile sed expression. command garbled: /^HOGEHOGE$/aFUGAFUGA
---
I read the source cord causing this error. In modules/filters/sed0.c
,l365〜l376,
there is following check.
---
case 'a':
commands->rep->command = ACOM;
if (commands->rep->ad2) {
command_errf(commands, SEDERR_AD1MES, commands->linebuf);
return -1;
}
if (*commands->cp == '\\')
commands->cp++;
if (*commands->cp++ != '\n') {
command_errf(commands, SEDERR_CGMES, commands->linebuf);
return -1;
}
---
It seems to require a backslash and a newline after "a" command.
In the "native" sed, this command works perfectly.
---
# sed -e '/^HOGEHOGE/aFUGAFUGA' textfile
---
Actually, sed man page says as following.
---
a \
text
---
I think this error check is unnecessary.
There is a similar check for the c and i commands.
Could you consider removing it?
Thanks.
