Tcl Library Source Code

Under some circumstances (large LDAP entries, e.g. with a large jpegPhoto), the LDAP module returns the following error:

Protocol error: Error reading SEQUENCE response for handle ::ldap::ldapsock15a3700

The ReceiveBytes proc seems to return 0 bytes (partial read) instead of the SEQUENCE byte. The partial read is treated as an error in MessageReceiver.

Ok. I Have not heard back from the submitters of the other tickets, for about 2.5 months. No need to hold back anymore.

This fix is now merged into both `trunk` and `tcllib-1-19-rc` (Latter is where the 1.19 release is currently getting prepared). The relevant merge commits are

• [0826350f8d] = `trunk`
• [2f3369f04b] = `tcllib-1-19-rc`

Your fix is now applied in commit [8b8f10e2bb],
on branch [fix-ldap-partial].

It is not merged to trunk yet, as I would like to ping the reporters of the two tickets you referenced to see if their issues are solved by this too.

Make refs actual links.
