Recursive grep crashing

[Guy Rouillier]

I've had this issue for awhile, but waited to report it until I tried the latest 4.43 release with SemWare Grep v2.05.  I'm still encountering it there.  I don't really know when this started, since it only happens under a particular condition.

In brief, the following use of the grep,exe shipped with TSE Pro: 

D:\Projects>grep -id terminal *.json

causes this crash:

However, if I switch one directory down, then grep succeeds:

D:\Projects\vscode>grep -id terminal *.json
SemWare Grep v2.05 for Win32 [Apr 14 2020]
Copyright 1996-2020 SemWare Corp. All rights reserved worldwide.

File: D:\Projects\vscode\.vscode\launch.json
    // "console": "integratedTerminal",
File: D:\Projects\vscode\GtkSharpApp\dot-vscode\launch.json
            // For more information about the 'console' field, see https://github.com/OmniSharp/omnisharp-vscode/blob/master/debugger-launchjson.md#console-terminal-window

And not all such uses of recursive grep crash.  For example, I just tried this, which succeeded, finding hundreds of occurrences many directories deep:

    D:\Projects>grep -id const *.java

Maybe it's encountering a .json file with a really long line length?

After sending, I discovered that by adding the verbose option -v, I could see exactly where grep was crashing:

=====

D:\Projects\kotlin\kotlin-eclipse\kotlin-eclipse-ui-test\common_testData\ide>grep -idv terminal *.json

SemWare Grep v2.05 for Win32 [Apr 14 2020]

Copyright 1996-2020 SemWare Corp. All rights reserved worldwide.

Searching D:\Projects\kotlin\kotlin-eclipse\kotlin-eclipse-ui-test\common_testData\ide\configuration\extractVersions\maven-central-response.json

--> Crashes here

=====

But if I descend one more directory down, grep does NOT crash:

=====

D:\Projects\kotlin\kotlin-eclipse\kotlin-eclipse-ui-test\common_testData\ide\configuration>grep -idv terminal *.json

SemWare Grep v2.05 for Win32 [Apr 14 2020]

Copyright 1996-2020 SemWare Corp. All rights reserved worldwide.

Searching D:\Projects\kotlin\kotlin-eclipse\kotlin-eclipse-ui-test\common_testData\ide\configuration\extractVersions\maven-central-response.json

--> Exits normally

=====

From this, I think grep must be encountering a path length issue.

This version did not crash when running several searches that have crashed for me previously.  So, looks great - thanks, Sammy!  I really prefer the simplified syntax compared to GNU grep, so didn't want to have to give it up.  Much appreciated.

Glad to hear it!
And glad to see that you're still around and kicking! :)

Thanks, and same to you. I genuinely appreciate that you've continued
to maintain the SemWare editors as long as you have. I started with
QEdit for DOS, then QEdit OS/2, and finally TSE. So, I've been on this
journey with you. :)

I started with QEdit for DOS, then QEdit OS/2, and finally TSE ...

Ditto.

Guy, methinks we're dating ourselves 😉

You are not alone. I started with Qedit v2.08 for DOS in the late 80's,
gifted from a work colleague at the time.
