uri_escape has changed?

gzevin

I use URI::esacpe and its function uri_escape a lot, especially in CGI scripts, in particular in file browse callout, etc.

While porting the callout to 6.1 I've noticed that, apart from area_path containing server name (which is teamsite's annoyance), uri_escape encodes everything, including some characters that are required to pass CGI parameters (say, & and = and ?) . I used to pass the whole string and it was Ok, but this time I had to rework the string so special characters were not encoded

anybody noticed this as well? if not, this is a warning

I encountered a problem with a custom perl library after the TS 6.1 upgrade that caused a file mover routine of mine to fail. I simply passed a parameter containing a file path (obtained from DCR w/o URI:escap'ing it) and all forward slashes (/) were replaced with %2F. This was a behavior I didn't see before the upgrade. *sigh*

When dealing w/ this issue, I checked the URI::Escape library and there were some significant changes. It looked like more characters would be encoded.

Hmm - have you read the perldoc on the latest version of URI::Escape? Looks like you can specify characters you want escaped rather than taking the default set which apparently includes characters it didn't use to (or so it seems from your post)

it means, this has to be put somewhere for the 5.5.2 -> 6 upgrade guide....

Greg, do you have a fix for this ?
I am in the process for upgrading from 5.5.2 to 6.1, and this customer uses the image browser callout which breaks because of changes in uri_escape, etc.

BTW, I believe the script I am porting is originaly your creation Smiley Happy

Do they send you the royalty ?

Well, if I was getting royalties from every client that has that callout, I would not be sitting now here ... sometimes I am not getting even thankyou..

This is actually why I am not realeasing my Rich Text Editor callout - that does almost everything that Visual Format does, but does not need any installations and has a tiny memory footprint.... - only to my clients...

now - back to business.

I am going to fix this myself. but - if you are in a hurry, it's done pretty easy - what you do - instead of doing uri_escape on the whole string, do it on every value of the CGI query string , i.e. leaving ? and = and & as they are. Also, you'd need to filter out server name from area_path .... Will take you 5 minutes to do...
