* | Revert some refcount changes on I/O structs.dgp2015-07-021-2/+2
| | | | | | | | | | | | | | These are refcounts on structs, not Tcl_Obj's. Their scheme doesn't suffer the same difficulties and histories as Tcl_Obj's, and they need not copy every detail, appropriate or not, from Tcl_Obj refcount management. The "significant value" -- as dkf puts it -- for the struct refcounting scheme is 0 not 1.

|/ / / | | | | | | | | | | | | | | | | | | Perhaps this is a welcome convenience for some callers, but not for Tcl's I/O system, which has no need for that. Added a new flag value TCL_ENCODING_NO_TERMINATE that callers can use to suppress this behavior. This means buffers don't require so much padding, and a tiny bit of processing is saved. Update I/O callers to use the feature.

Failure to do this locks up the channel - catastrophic FAIL. 2) After any driver call reports BLOCKED, don't call again. This is less serious, but FAILs to respect the non-blocking setting. Code corrections and tests included, to restore 8.5.15 compat.

| | | | | | | | | | | | | | | | | | | | | | | | | | | In a DoRead() revision, it came to favor making every effort to fill buffers, in preference to a more sensible goal of favoring avoiding calls out to the driver if there's already enough data in the buffers to satisfy the read operation. Result is many more calls out to recv() than are a good idea. Ought to show up most glaringly when many Tcl_Read() calls asking for small numbers of bytes (compared to buffer size) each, and that matches the reported case.

"Mask is an integer mask indicating which of the requested conditions actually exists for the channel; it will contain ***a subset of the bits from the mask argument*** to Tcl_CreateChannelHandler when the handler was created." (emhpasis added). Tcl_NotifyChannel is not honoring this. It passes a mask value that may contain bits not in common with the mask argument to T_CCH(). This commit is a one-liner patch adding in the masking step to make things behave as documented. Thanks to apn for digging this out. (In combination with other questionable code, this led to a hang in test http-4.6 on Windows) Tcl_NotifyChannel() has had this error in all of recorded Tcl history. It's hard to imagine any code dependent on it though. If any exists, it can be revised to pass the mask value it truly needs to T_CCH() and end up with code suitable both before and after this change. If you concur, please merge to core-8-5-branch, and I'll take it from there.
