hgweb: show a message when there are no more entries in the list

util.h: fix gcc version checking gcc doesn't have a predefined GCC_VERSION macro.

mq: remove unused repo._committingpatch-related code This was introduced in 20ad8f0512a2 but its usage was removed in 46cc3b74e1c5.

strip: set current bookmark to None if stripped

sslutil: backed out changeset 074bd02352c0 (issue4038) Python docs are a little unclear, but mpm reports reading the OpenSSL source code shows that PROTOCOL_SSLv23 allows TLS whereas PROTOCOL_SSLv3 does not.

httpclient: apply upstream revision da7579b034a4 to fix SSL problems (issue4038)

paper: call ajaxScrollInit in shortlog This just calls ajaxScrollInit at the shortlog page template with all needed agruments. So, infinite scrolling is working now there.

hgweb: add ajaxScrollInit function, which does the ajax requests and processing This function should be correctly called on a page, otherwise there is no effect. When called, it makes ajax requests for the next portion of changesets when the user scrolls to the end. Also, when the monitor is high so that the default amount of changesets isn't enough to fill it, multiple portions are loaded if needed after the page load.

check-code: add bracket style check

util.h: getbe32() and putbe32() use intrinsic function to improve performance Refer to https://bugzilla.mozilla.org/show_bug.cgi?id=351557. It can improve byte-swapping performance by intrinsic function.

hgweb: add appendFormatHTML javascript function This is a convenient helper function to append some formatted HTML markup to a DOM element.

hgweb: add removeByClassName javascript function It removes all elements with specified class name from the document.

hgweb: add docFromHTML javascript function It takes a string with HTML markup and creates DOM document from it. The implementation is a part of code from https://developer.mozilla.org/en-US/docs/Web/API/DOMParser#DOMParser_HTML_extension_for_other_browsers

hgweb: add makeRequest javascript function This function performs an asynchronous HTTP request and calls provided callbacks: - onstart: request is sent - onsuccess: response is received - onerror: some error occured - oncomplete: response is fully processed and all other callbacks finished

hgweb: add format javascript function It replaces placeholders like '%key%' with replacement values given.

hgweb: add nextentry variable for easy pagination in changelog nextentry always contains the first entry not shown on current page (if there is such entry)

hgweb: always compute all entries and latestentry in changelog Get the whole list of entries before rendering instead of using lazy evaluation. This doesn't affect the performance for usual case when the entries are shown anyway. When both entries and latestentry are used, this performs unnoticeably faster, and for pages which use only latestentry (quite uncommon case) it would be a bit slower. This change will make it possible to get the first entry of the next page easily without computing the list twice.

templatefilters: add short format for age formatting Implements a short output format for ages e.g. "1 second ago" is abbrevated as "1s ago".

hgweb: remove unused argument of changelist function in changelog This doesn't change the behavior as the argument isn't used anyway, and it's a preparation to the next patches,

context: move evolution functions from changectx to basectx This is just a code move and corrects an overlook from my previous patch series that assumed only a changectx would want this functionality.

context: use correct spelling of committable

check-code: check C patterns against .h files

check-code: make casting style check more precise

log: make file log slow path usable on large repos Running "hg log <pattern or directory>" on large repos took a very, very long time because it first read ctx.files() for every commit before even starting to process the results. This change makes the ctx.files() check lazy, which makes the command start producing results immediately.

plan9: update util.py for cpython 2.7 build

parse_manifest: rewrite to use memchr memchr is usually smarter than a simple for loop. With gcc 4.4.6 and glibc 2.12 on x86-64, for a 20 MB, 200,000 file manifest, parse_manifest goes from 0.116 seconds to 0.095 seconds.

parsers: correctly handle a failed allocation

parsers: use Py_INCREF safely

parsers: state is a char, not an int

setup: check if mercurial/util.h has been modified Before, if mercurial/util.h was modified but *.c wasn't, no extension was rebuilt.

util.h: add stdint basic type definitions MS C compiler v15 doesn't have stdint.h. Add basic int types those are defined in stdint.h.

hgweb: add revset syntax support to search This mode is used when all the conditions are met: - 'reverse(%s)' % query string can be parsed to a revset tree - this tree has depth more than two, i.e. the query has some part of revset syntax used - the repo can be actually matched against this tree, i.e. it has only existent function/operators and revisions/tags/bookmarks specified are correct - no revset regexes are used in the query (strings which start with 're:') - only functions explicitly marked as safe in revset.py are used in the query Add several new tests for different parsing conditions and exception handling.

revset: add a whitelist of DoS-safe symbols 'Safe' here means that they can't be used for a DoS attack for any given input.

revset: add helper function to get functions used in a revset parse tree Will be used to determine whether all functions used in a hgweb search query are allowed there.

revset: add helper function to get revset parse tree depth Will be used to determine if a hgweb search query actually uses any revset syntax.

parsers: use a lookup table to convert hex to binary This is a hotspot for parse_manifest. With this patch, for a 20 MB, 200,000 file manifest, parse_manifest goes down from 0.153 seconds to 0.116.

revlog: remove _chunkbase since it is no longer used This was introduced in 2011 for the lwcopy feature but never actually got used. A similar hook can easily be reintroduced if needed in the future.

revlog: move chunk cache preload from revision to _chunks In case we don't have a cached text already, add the base rev to the list passed to _chunks. In the cached case this also avoids unnecessarily preloading the chunk for the cached rev.

revlog._chunks: inline getchunk We do this in a somewhat hacky way, relying on the fact that our sole caller preloads the cache right before calling us. An upcoming patch will make this more sensible. For a 20 MB manifest with a delta chain of > 40k, perfmanifest goes from 0.49 seconds to 0.46.

revlog.revision: fix cache preload for inline revlogs Previously the length of data preloaded did not account for the interleaved io contents. This meant that we'd sometimes have cache misses in _chunks despite the preloading. Having a correctly filled out cache will become essential in an upcoming patch.

revlog: add a fast method for getting a list of chunks This moves _chunkraw into the loop. Doing that improves revlog decompression -- in particular, manifest decompression -- significantly. For a 20 MB manifest which is the result of a > 40k delta chain, hg perfmanifest improves from 0.55 seconds to 0.49 seconds.

perfmanifest: allow and require passing in a rev Previously perfmanifest would only test tip.

perfmanifest: fix cache invalidation The manifest cache is now stored in _mancache. The revlog cache is still stored in _cache.

lrucachedict: implement clear()

bundle: fix performance regression when bundling file changes (issue4031) Somewhere before 2.7, a change [ec896f9e8894] was committed that entailed a large performance regression when bundling (and therefore remote cloning) repositories. For each file in the repository, it would recompute the set of needed changesets even though it is the same for all files. This computation would dominate bundle runtimes according to profiler output (by 10x or more).

revset: fix wrong keyword() behaviour for strings with spaces Some changesets can be wrongly reported as matched by this predicate due to searching in a string joined with spaces and not individually. A test case added, which fails without this fix.

commitablectx: add a class that will be used as a parent of mutable contexts Currently, we have basectx that serves as a common ancestor of all contexts. We will now add a new class commitablectx that will inherit from basectx and will serve as a common place for code that will be shared between mutable contexts, e.g. workingctx and memctx.

workingfilectx: remove unneeded __repr__ since it is now inherited

workingfilectx: remove bogus comment

workingfilectx: remove __str__ manifest since it is now inherited

basefilectx: use basectx __str__ instead of duplicating logic This change allows us to only rely on one place to convert a context to a string which will help eliminate duplicate code in context.py

workingctx: remove unneeded manifest since it is now inherited
