journal: use fm.hexfunc() to get full hash in JSON/template output (BC) We generally do that.

py3: update test-check-py3-compat.t output The lower part of test-check-py3-compat.t runs only on py3 and hence its remain unchanged. Hence this patch updates the output so that change in output in the next patches will be only related to the change in the patch.

deprecation: enforce thew 'tr' argument of 'dirstate.write' (API) Compatibility was meant to be drop after 3.9 is released.

tests: remove initial bundle2 enabling in various bundle2 tests Bundle 2 is enable by default since 3.6 so we don't need this anymore. The remaining use of 'experimental.bundle2-exp' are there to test legacy behavior with bundle 1. Future patches will introduce a way outside of experimental to test that.

tests: remove bundle2 activation from test-largefiles.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

tests: remove bundle2 activation from test-tags.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

templatekw: change joinfmt to a mandatory argument of _hybrid object We've fixed several bugs caused by the misuse of the default joinfmt. Make it more explicit to prevent future bugs. dict.values()[0] is replaced by dict[element] as showlist() knows what the key is.

url: drop compatibility wrapper of socket.create_connection() It should be available on Python 2.6+.

doc: remove double imports of inspect from hgmanpage.py

merge: concatenate default conflict marker at parsing phase of .py "+" operations are unnecessary.

tests: remove bundle2 activation from test-push-warn.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

tests: remove bundle2 activation from test-phases-exchanges.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

tests: remove bundle2 activation from test-obsolete.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

tests: remove bundle2 activation from test-http-proxy.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

tests: remove bundle2 activation from test-hook.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

tests: remove bundle2 activation from test-acl.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

crecord: properly handle files with No newline at eof (issue5268) Yes, this bug was a single character with the wrong case...

annotate: pre-calculate the "needed" dictionary (issue5360) The "needed" dict is used as a reference counter to free items in the giant "hist" dict. However, currently it is not very accurate and can lead to dropping "hist" items unnecessarily, for example, with the following DAG, -3- / \ 0--1--2--4-- The current algorithm will visit and calculate rev 1 twice, undesired. And it tries to be smart by clearing rev 1's parents: "pcache[1] = []" at the time hist[1] being accessed (note: hist[1] needs to be used twice, by rev 2 and rev 3). It can result in incorrect results if p1 of rev 4 deletes chunks belonging to rev 0. However, simply removing "needed" is not okay, because it will consume 10x memory: # without any change % HGRCPATH= lrun ./hg annotate mercurial/commands.py -r d130a38 3>&2 [1] MEMORY 49074176 CPUTIME 9.213 REALTIME 9.270 # with "needed" removed MEMORY 637673472 CPUTIME 8.164 REALTIME 8.249 This patch moves "needed" (and "pcache") calculation to a separate DFS to address the issue. It improves perf and fixes issue5360 by correctly reusing hist, while maintaining low memory usage. Some additional attempt has been made to further reduce memory usage, like changing "pcache[f] = []" to "del pcache[f]". Therefore the result can be both faster and lower memory usage: # with this patch applied MEMORY 47575040 CPUTIME 7.870 REALTIME 7.926 [1]: lrun is a lightweight sandbox built on Linux cgroup and namespace.

bundle2: localize handleoutput remote prompts Code archaeology suggests that there was no good reason for this not to be localized. 'remote: ' is already localized elsewhere.

bundle2: fail faster when interrupted Before this patch, bundle2 application attempted to consume remaining bundle2 part data when the process is interrupted (SIGINT) or when sys.exit is called (translated into a SystemExit exception). This meant that if one of these occurred when applying a say 1 GB changegroup bundle2 part being downloaded over a network, it may take Mercurial *several minutes* to terminate after a SIGINT because the process is waiting on the network to stream megabytes of data. This is not a great user experience and a regression from bundle1. Furthermore, many process supervisors tend to only give processes a finite amount of time to exit after delivering SIGINT: if processes take too long to self-terminate, a SIGKILL is issued and Mercurial has no opportunity to clean up. This would mean orphaned locks and transactions. Not good. This patch changes the bundle2 application behavior to fail faster when an interrupt or system exit is requested. It does so by not catching BaseException (which includes KeyboardInterrupt and SystemExit) and by explicitly checking for these conditions in yet another handler which would also seek to the end of the current bundle2 part on failure. The end result of this patch is that SIGINT is now reacted to significantly faster: the active transaction is rolled back immediately without waiting for incoming bundle2 data to be consumed. This restores the pre-bundle2 behavior and makes Mercurial treat signals with the urgency they deserve.

revset: fix keyword arguments to go through optimization process Before, a keyvalue node was processed by the last catch-all condition of _optimize(). Therefore, topo.firstbranch=expr would bypass tree rewriting and would crash if an expr wasn't trivial.

help: add example of '[templates]' usage V2: - move from shortest() with minlength 8 to minlength 4 - mention [templates] in config.txt - better describe the difference between [templatealias] and [templates] V3: - choose a better example template
