QUESTION
There is a commit in my hg repository with hash 123abc. This is the last commit I made in the repo. When I run hg diff --from 123abc, I see no output. When I run hg log --graph, I see an @ next to 123abc.
In Git this commit would be called "HEAD". I'm not sure what it's called in Mercurial. It is not the "tip", because I pulled other changes after the last time I committed (and hg log -r tip shows commit 456def).
What is this commit/head called?
...ANSWER
Answered 2022-Feb-14 at 17:23If 123abc has no children, then it is a "head".
A head is a changeset with no child changesets. The tip is the most recently changed head. Other heads are recent pulls into a repository that have not yet been merged.
(https://www.mercurial-scm.org/wiki/Head)
Regardless whether the current working directory derives from a head or a non-head, I would refer to the commit that precedes it as the "working directory parent" changeset or commit. (That may just be the term my team uses - not sure it is "official".)
The parent may be visible in a GUI tool (like Tortoise) or you can get it using hg parent.
Based on the statements about 456def I'm a little confused whether it has no children, or not? (Maybe update the question to clarify / add more detail)

I have generic mergeArrays which does not depend on order of parameters.

QUESTION
Some years ago, Mercurial | TortoiseHG could exchange data bidirectionally easy with at least 2 Big Brothers:
- Subversion, using HGSubversion
- Git, using HG-Git
Current (6.0 versions of family) state - the ordinary users have none:
- hg-subversion is broken (extension can't be loaded), bundled with THG (Mercurial ???) extension not updated since 2019
hgsubversion: 6a6ce9d9da35 2019-04-19(extraction from myTortoiseHg\extension-versions.txt), external SVN-bindings exist only for Python 2.7 (while py3-movement inside Mercurial is live and active) - hg-git got some big troubles, starting from THG 4.9 (manual patching of library.zip was required), on 6 version the situation has gotten better (no patching), but still unsatisfactory for the common user - installing Python 2.7 (for single-user) and using
pipisn't The Right Way (tm)
Are there any comments, additions, clarifications, recommendations on how to do it (if what I am doing is wrong)?
Addition after some testing: special verson tortoisehg-6.0hggit-x64.msi from Matt Harbison at least allow using hg-git with ssh-transport (not http yet) and can be recommended for every-day usage by ordinary user.
...ANSWER
Answered 2022-Mar-04 at 18:12So, as a current maintainer of hg-git and former contributor to hgsubversion, I think I can provide some context here.
Regarding hgsubversion, the short answer that it is either dead or — at best — extremely dormant. Personally, I have not interacted with a Subversion repository in years, and that's a common experience. No-one has been sufficiently motivated to fix bugs, keep it working, and — last, but not least — make it work with Python 3.
For hg-git, a period of semi-dormant state meant that the TortoiseHg maintainers stopped bundling it. We now keep up with Mercurial releases, and I've requested that they reverse that decision. I believe they bundle Dulwich, but as I don't use Windows, I can't say for sure. That said, it's quite reasonable to want to use hg-git with TortoiseHg, and if you run into any specific issues, I'd suggest you file a bug with them — or perhaps add a comment to the bug I linked earlier.
Generally speaking, you should be able to use 0.10.x version of hg-git with most versions of TortoiseHg, as I believe they bundle Dulwich. In that case, enabling the extension should be as simple as:

I'm trying to make get requested with .Q.hg (HTTP get), but I need to edit the request headers to provide API keys. How can I do this?
ANSWER
Answered 2021-Dec-29 at 02:34You can try this function I wrote a few years back for a POC (similar reason - I needed to supply multiple headers). It's based on .Q.hmb which underpins .Q.hp/hg. Please note - it was never extensively tested & there are likely better alternatives out there, but it will perhaps work as a quick solution.

FIXED: While upgrading Ubuntu 21.04 to 21.10 firefox (previously installed with apt) got removed and installed with the snap-version. Reversing (uninstalling the snap version & reinstalling with apt) this fixed my issue.

QUESTION
In the "computing minrun" section of the TimRun document, it gave a good and a bad example of selecting the minrun for N=2112 array. It states using minrun = 32 is inefficient because
runs of lengths 2048 and 64 to merge at the end The adaptive gimmicks can do that with fewer than 2048+64 compares, but it's still more compares than necessary, and-- mergesort's bugaboo relative to samplesort --a lot more data movement (O(N) copies just to get 64 elements into place).
it also described the minrun = 32 algo as:
then we've got a case similar to "2112", again leaving too little work for the last merge to do
It then stated that choosing minrun = 33 will end up with a perfectly balanced merge which is better.
If we take minrun=33 in this case, then we're very likely to end up with 64 runs each of length 33, and then all merges are perfectly balanced. Better!
My questions are why is merging perfectly balanced sorted arrays better than imbalanced arrays if the total element count is the same(2112 in the example)?
why is minrun=32 "doing more compares than necessary" when the total element is also 2112 for minrun=33?
why is there "more data movement"?
why does the last merge have "too little work to do"?
My understanding is, merging sorted arrays of size A & size B will take O(A+B). Why is it more efficient when A & B are the same size?
I drew diagrams of how the 2 minrun scenarios are executed but I'm still confused.
...ANSWER
Answered 2021-Aug-25 at 18:34For 2112 elements if all runs are size 33, then it will take 6 steps to merge from 33 to 2112: 33 -> 66 -> 132 -> 264 -> 528 -> 1056 -> 2112. If all runs are size 32, it will take 7 steps to merge from 32 to 2112: 32 -> 64 -> 128 -> 256 -> 512 -> 1024 -> 2048 -> 2112.
If you do the math, with minrun = 33, the entire array is processed in 6 steps, with minrun = 32, nearly the entire array (2048 elements) is processed in 6 steps, then the entire array is processed in the 7th step.
QUESTION
Recently, I'm reading Java Source Code, e.g. ArrayList, ArrayDeque, LinkedList, etc. I found when they want to use some class field in class method, they will always declare a final local variable which equals to the field. However, if I haven't read the source code, I will never consider doing this thing. Is it a good practice to do so? Or why does Java Source Code choose to do so? What's the advantage, like the performance?
Reference:
Example: getFirst() in LinkedList
...ANSWER
Answered 2021-Jun-19 at 22:48This is a micro-optimisation which probably makes sense for standard library code which is going to be used by lots and lots of people and read by significantly fewer people. I wouldn't recommend doing this in your own code unless performance is a real concern and you've profiled your application to determine which parts of the code are the real bottlenecks, since otherwise the performance gain is likely to be negligible, so the main effect will be to make your code more verbose.
Using local variables should have some very minor performance benefits, because:
- Local variables will be allocated either on the stack or in registers, which are faster to access than other memory, so doing only a single field access from the heap definitely minimises the number of slower accesses (at best, accessing memory on the heap can only be as fast as accessing a local variable, but at worst it can be slower).
- The bytecode instructions for accessing local variables are shorter. The first four local variables can be loaded using
aload0,aload1,aload2andaload3, which are a single byte each, andaloadis two bytes including an index to the local variable to be loaded. In comparison,getfieldtakes three bytes, two of which are used to reference the field being accessed.
There is also potentially a semantic difference in non-synchronised methods, since the local variable will hold the same value even if the field is changed by another thread during the method execution. However, most of the standard library classes you'll see this pattern in are not meant to be thread-safe, and even if the class is meant for concurrency, doing this doesn't necessarily make the method thread-safe anyway.

Install hg
You can use hg like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
