Pike 8.1 type errors

When I try to start my SPike webserver daemon on a bleeding edge Pike I get this list the of errors and warnings below. The version of Pike I'm getting this with is: commit 8c6986783aead46ed2eac8fb90d5d300dc6a5f68 (HEAD -> master, origin/master) Author: Henrik Grubbstr<C3><B6>m (Grubba) <grubba(a)grubba.org> Date: Fri Apr 9 19:37:43 2021 +0200 Compiler [Typechecker]: Fix NULL-deref in even_lower_and_pike_types(). The last time I had a bleeding edge "standard" pike that actually worked for me was: commit 94a868dae24642de2e71e0a6079a27aabae32132 Author: Stephen R. van den Berg <srb(a)cuci.nl> Date: Tue Feb 2 23:07:53 2021 +0100 So, since then I've been maintaining a last-known-good version for private use, and did all further development on that. lib/modules/__builtin.pmod/Nettle.pmod/MAC.pike:82: Warning: An expression of type mapping(zero:zero) | mapping(string(7bit):int | string(7bit)) cannot be assigned to a variable of type void | mapping(string(7bit):int | string(7bit)). lib/modules/__builtin.pmod/Nettle.pmod/Hash.pike:250: Warning: Type mismatch in argument 1 to encode_base64url. lib/modules/__builtin.pmod/Nettle.pmod/Hash.pike:250: Warning: Expected: string. lib/modules/__builtin.pmod/Nettle.pmod/Hash.pike:250: Warning: Got : string(8bit) | mixed. lib/modules/__builtin.pmod/Nettle.pmod/Hash.pike:1143: Warning: An expression of type mapping(zero:zero) cannot be assigned to a variable of type mapping(string:string(8bit)). lib/modules/__builtin.pmod/Nettle.pmod/Hash.pike:1153: Warning: An expression of type mapping(zero:zero) cannot be assigned to a variable of type mapping(string:string(8bit)). lib/modules/__builtin.pmod/Nettle.pmod/Hash.pike:1153: Warning: An expression of type mapping(zero:zero) cannot be assigned to a variable of type mapping(string:string(8bit)). lib/modules/__builtin.pmod/Nettle.pmod/Hash.pike:1253: Warning: An expression of type zero | string cannot be assigned to a variable of type string. lib/modules/__builtin.pmod/Nettle.pmod/ECC_Curve.pike:131: Warning: An expression of type mapping(zero:zero) cannot be assigned to a variable of type mapping(string(7bit):int | string(8bit) | { mpz = object(implements _static_modules.Gmp()->mpz) }). lib/modules/Standards.pmod/ASN1.pmod/Types.pmod:70: Warning: Wrong return type. lib/modules/Standards.pmod/ASN1.pmod/Types.pmod:70: Warning: Expected: int(1..). lib/modules/Standards.pmod/ASN1.pmod/Types.pmod:70: Warning: Got : zero. lib/modules/Standards.pmod/ASN1.pmod/Types.pmod:200: Warning: An expression of type mapping(zero:zero) cannot be assigned to a variable of type void | mapping(string:int). lib/modules/Standards.pmod/ASN1.pmod/Types.pmod:936: Warning: Type mismatch in argument 2 to sprintf. lib/modules/Standards.pmod/ASN1.pmod/Types.pmod:936: Warning: Expected: int | object. lib/modules/Standards.pmod/ASN1.pmod/Types.pmod:936: Warning: Got : int(0..) | array() | string | mixed. lib/modules/Standards.pmod/ASN1.pmod/Types.pmod:1152: Warning: An expression of type void | mapping(int:program({ Object = object(implements object(/home/srb/81pike/lib/modules/Standards.pmod/ASN1.pmod/Types.pmod).Object) })) cannot be assigned to a variable of type mapping(int:program({ Object = object(implements object(/home/srb/81pike/lib/modules/Standards.pmod/ASN1.pmod/Types.pmod).Object) })). lib/modules/Val.pmod/module.pmod:440: Warning: Invalid type. lib/modules/Val.pmod/module.pmod:440: Warning: Expected: function(void | mixed ... : object) | object | program | type(mixed). lib/modules/Val.pmod/module.pmod:440: Warning: Got : zero. lib/modules/Val.pmod/module.pmod:685: Warning: Wrong return type. lib/modules/Val.pmod/module.pmod:685: Warning: Expected: mapping(string:int). lib/modules/Val.pmod/module.pmod:685: Warning: Got : mapping(zero:zero). lib/modules/Standards.pmod/ASN1.pmod/Decode.pmod:121: Warning: An expression of type zero | program({ Object = object(implements Standards.ASN1.Types.Object) }) cannot be assigned to a variable of type program({ Object = object(implements Standards.ASN1.Types.Object) }). lib/modules/Standards.pmod/X509.pmod:105: Warning: Illegal to redefine inherited variable tag with different type. lib/modules/Standards.pmod/X509.pmod:105: Warning: Expected: int(1..). lib/modules/Standards.pmod/X509.pmod:105: Warning: Got : int(1..) | zero. lib/modules/Standards.pmod/X509.pmod:114: Warning: Illegal to redefine inherited variable tag with different type. lib/modules/Standards.pmod/X509.pmod:114: Warning: Expected: int(1..). lib/modules/Standards.pmod/X509.pmod:114: Warning: Got : int(1..) | zero. lib/modules/Crypto.pmod/RSA.pmod:26: Warning: Type does not contain zero for variable without initializer n.

Pike 8.1 segfault compiling unknown name

02 Apr '21

int main() { //compile("void x(int id) {boom = ({id});}"); compile("void x(int id) {boom += ({id});}"); } The first (commented-out) line will raise a standard exception regarding the unknown name "boom". The second will segfault the interpreter. The crash appears to happen deep inside grammar handling, possibly involving some type handling? Not sure. Any ideas? ChrisA

Shuffler revisited (2)
by Stephen R. van den Berg 18 Mar '21

18 Mar '21

In an attempt to prepare the Shuffler for use on the database connection in the pgsql module, I delved back into the Shuffler code again. This time I achieved 99.9% comprehension of the code. The result is a considerable rewrite of the inner loop. The rewrite was necessary because: a. The shuffle-source-management still had memory leaks. b. The size of the buffer writes was arbitrarily large (depending on the input block size). c. The way wrap_callback results were stored resulted in (only) mostly-correct data. d. The data of sources were used ever so briefly *after* getting freed. -- Stephen.

debugger-wip merge

Hello all- I’m planning on merging the work in progress debugger into master in the coming days. A prior version of this code has been reviewed and it is my understanding from Mateusz that there were 1 or 2 unaddressed items. I’ve addressed one (handling of multiple offsets for a given line) and don’t think the other item (in what file a particular set of functions belongs) makes sense at the moment, based on my read of the code. I wouldn’t however, be opposed to someone who feels more strongly about relocating it. I’ve made a few other minor enhancements to the C-level code that I don’t think negatively impact the outcome of that review. The first thing to know is that the debugger actually works[1]. My plan is to split the code into 2 or 3 parts: the C-level bits, the debugger itself which lives in lib/modules/Debug/Debugger.pmod and the bootstrap code in master.pike. When it lands, I’ll also have some instructions for how to try it out. My base assumptions (hopefully obvious but I’ll state them nonetheless): 1. When not enabled at runtime, it is intended that the code is not in the path of execution. 2. When enabled, the code should not cause aborts. 3. "Surprise" behavior is possible, some of which is known[2] and some not. 4. Performance is assumed to be impacted while debugging. Attempts to minimize the negative impact are obviously of interest. 5. Everything here is private/uncommitted and subject to change should something better rear its head. Some caveats: 0. This is very much work in progress, but I commit to minimize impact to others and get things to a point where that’s no longer the case as quickly as possible. I felt it important to get this code out in front of more people to look at and try. Specifically: 1. I’ve made a good faith effort to not commit known bugs, but I’m sure there are some and will investigate any problems identified. 2. There is vestigial code that I’ve left in place to ease the inevitable troubleshooting and confidence building that are coming. The plan is to remove them when they are no longer needed. 3. There is behavior that might be pared back (specifically related to breakpoints across a range of offsets, which may not be needed). 4. The Pike level code is where most of the action currently is, and is most likely to see major change. 5. Semi-related: there /seems/ to be a problem in LiveBacktraceFrame in that argument names aren’t available, and it appears they’re not making it out of the compiler intact. I haven’t been able to track down the source of that problem. Assistance would be welcome. If anyone sees a major problem in any of this, please let me know.
