Re: SIGSEGV trying to conver html entities to theiractual printable codes

Eli Zaretskii — 2013-05-17T18:49:23

Your program doesn't segfault for me, neither with Gawk 3.1.6 nor with
the latest Gawk 4.1.0, also on Windows XP SP3.  I suspect that your
Gawk is broken (there are quite a few broken ports to Windows floating
around).  I suggest to switch to using this port:

  http://sourceforge.net/projects/ezwinports/files/gawk-4.1.0-w32-bin.zip/download

The above is the Windows port recommended by the Gawk maintainers.

SIGSEGV trying to conver html entities to their actual printable codes

Luna Rodríguez, Raúl — 2013-05-17T12:16:36

Hello:

I found that when I run the awk I've send to you and execute "awk -f fail.awk failhtml" the program just gets and Segmentation Fault.

What's wrong with it?

I am using gawk version 3.1.6 for windows under Windows XP 32 bit. Version of XP: 5.1 (Build 2600.xpsp_sp3_gdr.120411-1615).

Thanks in advance

Putting the answer above the question ;-)

Re: zerofile

david ward — 2013-05-17T11:30:49

correction:
zerofilef.awk should be
#!/usr/bin/gawk -f
function zerofile(ARGV[Argind, Argind )
{
   print ARGIND,Argind, ARGV[Argind]

}
Output is
nonempty empty2
gawk: zerofilef.awk:2: function zerofile(ARGV[Argind, Argind )
gawk: zerofilef.awk:2:                       ^ syntax error
gawk: zerofilef.awk:2: error: function `zerofile': can't use special
variable `ARGV' as a function parameter
This my last email on this function; I don't want to become a nuisance
rather than a help

First af all, some advice:

- Please don't top-post.
- Please respond to the bug-gawk list instead of or in addition to my 
personal e-mail address.
- Please post just plain text and not HTML.
- Please quote the relevant parts of the original message, and not the 
whole stuff.

(Disclaimer: I'm quoting the full thread so others can see the whole stuff 
you sent just to my personal address)

Short answer: Your original code (at the end of this long post) is correct. 
Don't spoil it.

And now, look below to see my responses to some specific parts of your 
messages.

Don't worry. We are always willing to help interested people.

But, your original code is correct, so don't try to amend it. Doing so just 
makes things worse.


ARGC is a scalar variable (the number or arguments), ARGV is the array of 
arguments. So ARGV[x]is correct, but ARGC[x] doesn't makes sense.

In addition, ARGC is a special variable, so you can't use this name for a 
formal argument of a functio

Aharon Robbins — 2013-05-17T07:21:05

Hi. Can you please send your program and your data as attachments, so
that I don't have to worry about mail mangling them?  Also, please let
me know what locale you are using.

And, can you try the just-released gawk 4.1.0, available from the
GNU distribution site?

Thanks,

Arnold

gawk bug

Steven Daniels — 2013-05-16T07:50:45

I'm getting an Assertion failed when I try the following:





The point of failure seems to be "[地]", when brackets aren't used, the command works as expected.

$ echo '很?pos=ad 宽广?pos=va ， 更?pos=ad 是?pos=vc1' | gawk '{match($0, /(([^ \?.]*\?pos=ad |([^ \?.]*\?pos=(jj|va) )地\?pos=dev ){0,2})/ , arr)}  { if(arr[0]) print arr[1], arr[4], $6} '

I don't know if this a bug or not but I get a syntax error when when trying
to pass ARGC[Argind] to zerofile. gawk version: 4.0.2 OS: Ubuntu 12.4

#!/usr/bin/gawk -f
# All known awk implementations silently skip over zero-length files. This
is a by-product of awk's implicit
# read-a-record-and-match-against-the-rules loop:
#  when awk tries to read a record from an empty file, it immediately
receives an end of file
# indication, closes the file, and proceeds on to the next command-line
data file, WITHOUT executing any
# user-level awk program code.
# Using gawk's ARGIND variable , it is possible to detect when an empty
data file
# has been skipped.

     # zerofile.awk --- library file to process empty input files


     BEGIN { Argind = 0 }

     ARGIND > Argind + 1 {
           v = ARGV[Argind]
         for (Argind++; Argind < ARGIND; Argind++)
             zerofile(a, Argind) # get syntax error for ARGV[Argind]

     }

     ARGIND != Argind { Argind = ARGIND }

     END {
         d = ARGV[Argind]

Re: Documentation, section: 16.8 The gawkextlib Project

Hermann Peifer — 2013-05-16T10:05:23


Thanks for taking care.

After looking twice, I noted that Annex B.2 (Compiling and Installing 
gawk on Unix-like Systems) does not mention any "make install", whereas 
annex B.3 (Installation on Other Operating Systems) does mention the 
installation step.

So I suggest to mention "make install" in Annex B.2, in particular as 
its title promises that this section is also about installing gawk.

Hi.  On further review, I've concluded that you are correct and it's a bug.

Hi.  Can you please send me the full script you are using? (wc.ack)

A quick glance makes it look like you are correct but I would like to
see the full code and review this more carefully.

It would help if you would send both your program and your data files
as attachments, to avoid any mangling by mail programs.
