Optimised map
by Martin Karlgren 09 Jan '17

09 Jan '17

Hi, Having realised the benefits of functional programming, I’ve been quite annoyed by the rumour of how expensive function calls are in Pike. I decided to look into f_map and could see how much seemingly unnecessary work it does when it calls apply_svalue once for each entry in the array – it should be possible to reuse the pike_frame if it’s about to be thrown away after the function call (if it has other refs on the other hand, it can’t be reused – it’s probably used as a scope in some … [View More]

Promises in Pike vs other languages
by Marcus Agehall (nu med K-m�rkt fastighet och ny elcentral) ＠ Pike (-) developers forum 09 Nov '16

09 Nov '16

I have spent some time looking at the new stuff in Concurrent.pmod that Grubba has added to 8.1. Mostly it is code relating to the concept of Promises and Futures which are very popular amongst JavaScript people these days. I have noted that there seems to be some rather striking differences between how JavaScript treats promises and how Pike does it. I'm not sure this is a good thing(tm) and therefore I'd like to bring this up before 8.1 stabilizes. In Pike, we have two methods that register … [View More]

Re: Promises in Pike vs other languages

Something I would recommend, from having written heaps of asynchronous object based systems, with or without remote computers involved, is to treat all references to the promise object going away as an error, and avoid un-needed circular references. This makes it easy to detect when you accidentally forget the object. Also, having the object be callable is rather convenient, it can then be put as a normal callback in all the various function based API:s we already have. >From the MiniRPC … [View More]

Documentation breakage

Just to make sure we're talking about the same thing, the patch I posted has been applied, but the patch I didn't post hasn't. 5c6616146a1f1cdb18a8ed6f973a63ee73df9278 is the current version of Sign.pike on the 8.0 branch, isn't it?

Documentation breakage

When preparing a new Debian package of 8.0.240, I noticed that some documentation disappeared, apparently due to the following. The error in Nettle.Sign is already corrected but not the others, AFAICT, and I'm guessing that @exp should be @expr. Patch below, which I home someone can apply right away.

Notes from the impromptu developer meetup 2016-07-07
by Peter Bortas 21 Jul '16

21 Jul '16

We had that impromptu Pike dev meetup on the 7th, and I took notes on some of the things we discussed. Dumping them here before we all forget about it. In attendence: Zino, Nilsson, Grubba, Marcus, Tobi, Arne Status report ------------- Per tradition grubba made a short status report about what has changed since the last meeting: - Some non-enabled new SSL server stuff is not yet compatible with Chrome - We enforce C89 now - GMP is required and always loaded in 8.1 - Threads are allowed … [View More]while compiling in 8.0 - pragma #dissasemble/#dissassemble (new in 8.1) 8.2 TODO -------- We went though what everyone wants in before we split branch 8.2. In no particular order: - Compiles on Windows For now and until he protests this is zino's problem. - Something about Mpz. Don't remember the details. - Something about lfuns proxy-requested by Per. Don't remember the details. - Add MPI support zinos project. Not really a blocker. - Stop using declarations on the top of the function in C? Debatable - Get the fastcall, fast frames improvements in - glob("C:\*.gif") alt 1: Add Future.glob() depricate glob() import Future alt 2: Consider this a Windows problem and call up the 3 Windows users by phone. alt 3: //Never do this Add heuristics. alt 4: add 8.2::glob dspecial depricate glob constant glob=8.2::glob alt 5: Add String.glob() or similar depricate glob() Maybe reintroduce glob() in a later release We where leaning towards 5. - Stop dumping modules - Move/Remove the Markdown non-module Random notes ------------ - Make a list of all modules and make a note about why each of them are included. Remove the ones with no motivation for them. Nilsson is responsible for the list-making. - Check if anything runs on eureka, otherwise, kill it - Check if we have anything on pelix, otherwise kill it - TravisCI / Coverage - Opera Critic (https://github.com/jensl/critic) Someone said they would have a look att setting that up for Pike last meeting. No one could remember who. - Xenofarm Dates are broken somewhere on the buildmachine which prevents some of the clients from building. - _Roxen module, move the useful stuff somewhere and kill it Make one canonical HTTP module. - Rewrite dirnodes to make them have fewer confusing edge-cases nilsson, grubba - dot-operator is confusing as hell - Use merges to make it easier to track that bugfixes has been merged in which branch Arne will check. - Remove configurability of Calendar Nisson - Make Calendar discoverable for users - Take a look at Image.Orient - Take a look at Image.Graph - Documentation for stuff that inherits ::this_program - Ticket support?

f_hash() and endianess
by Arne Goedeke 06 Jul '16

06 Jul '16

The documentation of the new f_hash() claims that its return value is architecture independent. SipHash reads its input as a series of little-endian 64 integers, which means that the hash value depends on endianess for wide strings. I have at some point written byte order independent versions of siphash for both 16 and 32 bit strings. Those can be found in commit 21f218e51d55d8c07aff9db0cf45e4ac83050a5e as part of the bloom filter branch. If nobody objects, I will merge that commit into pike 8.… [View More]
